FORWARD LOOKING STATEMENTS

The discussion of forward looking statements in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operation, is incorporated herein by reference.

PART I

Item 1. BUSINESS

SIERRA PACIFIC RESOURCES

Sierra Pacific Resources, hereafter known as SPR, was incorporated under Nevada law on December 12, 1983. SPR's mailing address is P.O. Box 30150 (6100 Neil Road), Reno, Nevada 89520-3150 (89511).

SPR has eight primary, wholly owned subsidiaries: Nevada Power Company (NPC), Sierra Pacific Power Company (SPPC), Tuscarora Gas Pipeline Company (TGPC), Sierra Pacific Communications (SPC), Sierra Energy Company, dba e. three (e. three), Sierra Pacific Energy Company (SPE), Lands of Sierra (LOS) and Nevada Electric Investment Company (NEICO). NPC and SPPC are referred to together in this report as the "Utilities".

AN EXPLANATION OF THE REPORTING FORMAT

The merger between SPR and NPC on July 28, 1999 was treated for accounting purposes as a reverse acquisition and deemed to have occurred on August 1, 1999. As a result, for financial reporting and accounting purposes, NPC was considered the acquiring entity under Accounting Principles Board Opinion No. 16, Business Combinations, even though SPR became the legal parent of NPC. Because of this accounting treatment, the financial information for the year ended December 31, 1999 reflects the acquisition of SPR by NPC on August 1, 1999. Therefore, the results of operations for that year reflect twelve months of information for NPC and five months of information for SPR and its pre-merger subsidiaries. This presentation is carried forward to the notes to the financial statements.

The discussion in this report has been divided wherever possible to highlight the activities of the major subsidiaries of SPR. Parenthetical references are included after each major section title to identify the specific entity addressed in the section. References to SPR refer to the consolidated entity, except for the section related to debt financing in which SPR debt is discussed separately from that of its subsidiaries.

INDUSTRY AND REGIONAL PROBLEMS AFFECTING The Utilities (NPC and SPPC)

Electric Utility Trends

The year 2001 was challenging and unpredictable for the electric utility industry, marked by volatile and uncharacteristic power prices, deterioration in the credit quality of a number of utilities and power merchants, bankruptcy of a major California utility and a major Houston based energy trading company, and increased involvement and oversight by government and regulators.

Dramatic increases in wholesale power prices that began in 2000 continued into the first half of 2001, particularly in the West. Rolling blackouts occurred in California. Wholesale energy prices in the West peaked in the spring at levels up to four times what they were in the prior year. While continuing blackouts and high power prices were predicted in the second half of the year, they did not materialize. Instead, power prices moderated largely because of mild weather across the United States, lower natural gas prices, conservation in California, and the imposition by the FERC of federal price caps in California and eleven western states,

including Nevada (see Regulation and Rate Proceedings, FERC Matters in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations). Remaining as a result of this energy price volatility is a long list of policy, regulatory, business and financial issues, many of which are being addressed at both state and federal levels.

California continues to influence the region. In California, continued high prices during the first half of the year and the lack of adequate rate relief led to an inability to purchase energy, and credit problems and defaults for the state's three largest utilities. In April 2001, Pacific Gas & Electric Company filed for bankruptcy. The State of California took on the role of energy buyer through its Department of Water Resources and funded billions of dollars for short and long-term energy purchases which it plans to fund through the issuance of bonds. While California's regulatory and policy issues are specific to California, the state's problems exacerbated western energy problems and left a mark throughout the region as western states continue to struggle with the question of who should pay large fuel and purchased power balances.

Like other utilities in the West, the Utilities, which operate principally in Nevada, have been significantly impacted by increased wholesale prices. High fuel and power costs have led to large financing requirements, liquidity constraints and depressed earnings. In Nevada, emergency legislation, Assembly Bill (AB) 369, was enacted in April 2001 to control volatility in the price of retail electricity in Nevada and to ensure the Utilities the financial resources to provide adequate and reliable electric service. To achieve these purposes, AB 369 allows the Utilities to recover in future periods their costs for wholesale power and fuel, subject to regulatory review for prudency. NPC filed for recovery of deferred energy balances on December 1, 2001 and SPPC filed for recovery of deferred energy balances on February 1, 2002. The businesses of SPR, NPC, and SPPC are substantially dependent upon the outcomes of these proceedings. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations for further legislative and regulatory discussions. Also in December, the Utilities filed an action under Section 206 of the Federal Power Act seeking a rollback of wholesale power prices and refunds.

High energy prices, power shortages, and a push at state and federal levels for increased supply resulted in an unprecedented number of new power plant project announcements nationally and in Nevada - mostly unregulated and mostly natural gas-fired. Some power plants have been built or are under construction. NPC is constructing transmission facilities to interconnect new merchant plants being built in southern Nevada (see Nevada Power Company, Transmission, for a discussion of the Centennial Plan). Towards year-end, a weakening economy, lower demand, and a decline in energy prices have caused power plant builders to reconsider planned projects. Some have announced downsizings or cancellations. In addition, falling energy prices and pressure from the major credit rating agencies have caused the announcement of a number of asset sales.

In Nevada, the Utilities' divestiture of generation assets, which the PUCN had previously ordered, was halted by the provisions of AB 369 that prohibit the sale of generation assets until July 2003. Additionally, in April 2001, SPR and Enron Corporation (Enron) mutually agreed to the termination of their agreement for SPR's purchase of Enron's wholly owned subsidiary, Portland General Electric (PGE), headquartered in Portland, Oregon.

National energy policy is also undergoing change due to the events of 2000 and 2001. The President's National Energy Policy Report was issued in May 2001. Recently, Senate Bill (SB) 517 addressed the Public Utility Holding Company Act (PUHCA) repeal and the Public Utility Regulatory Policies Act (PURPA) reform, some FERC provisions, reliability, utility mergers, open access transmission, net metering and interconnection. Senate action on the bill is pending.

Regulation and Electric Restructuring

The transition to retail competition continues to be highly uncertain, driven by the development of a relatively young wholesale market and the different approaches to retail competition taken by state regulators and legislators. Rising wholesale prices, the western energy crisis, and the recent bankruptcy filings of Pacific Gas & Electric Company and Enron have led many states to review or revise restructuring plans.

While deregulation has been suspended in some states, in other states, the process has slowed. In Nevada, AB 369, which became law in April 2001, repealed all statutes authorizing retail competition in Nevada's electric utility industry and voided any license issued to alternative sellers in connection with retail competition. AB 661, passed in July 2001, enables large customers with demand of one megawatt (MW) or more to choose a new energy supplier beginning mid-2002 with permission from the PUCN upon meeting public interest tests.

Remaining committed to regional transmission organization development and power competition, FERC plans to propose electric market design rules and issue a final ruling by year-end 2002. Also, FERC recently approved the nation's first regional transmission organization in the Midwest.

NEVADA POWER COMPANY

NPC is a Nevada corporation organized in 1921. NPC became a wholly owned subsidiary of SPR on July 28, 1999. Its mailing address is 6226 West Sahara Avenue, Las Vegas, Nevada 89146.

NPC is a public utility engaged in the distribution, transmission, generation, purchase and sale of electric energy in Clark County in southern Nevada. It provides electricity to approximately 639,000 customers in the communities of Las Vegas, North Las Vegas, Henderson, Searchlight, Laughlin and adjoining areas. Service is also provided to Nellis Air Force Base and the Department of Energy at Mercury and Jackass Flats at the Nevada Test Site.

Business and Competitive Environment

NPC's electric business contributed 100% of its 2001 operating revenues of $3.025 billion. The system has an annual load factor of approximately 49.0%, which is slightly lower than the industry norm of 50% to 55%.

Summer peak loads are driven by air conditioning demand. NPC's peak load increased an average of 5.8% annually over the past five years, reaching 4,412 MW on July 2, 2001. NPC's total electric megawatt-hour (MWh) sales have increased an average of 5.8% annually over the past five years. Winter peak loads are low relative to the summer peak. Winter load above the base amount is driven by air handling in forced air furnaces.

NPC's service territory continues to be one of the fastest growing areas in the nation. A significant part of the growth in NPC's electric sales has resulted from new residential, industrial, and gaming customers.

NPC's electric customers by class contributed the following toward 2001 and 2000 MWh sales:

Tourism and gaming remain southern Nevada's premier industries. Over 35 million tourists visited Las Vegas in 2001, infusing approximately $19.8 billion into the local economy during the year. Currently, Las Vegas is the home of 18 of the world's 20 largest hotels. No mega-resort properties are scheduled to open during 2002. Hotel room growth is expected to be just 0.8% during 2002.

The Las Vegas Convention Center has recently completed a $150 million expansion project, adding 918,000 square feet of exhibit space and 90,000 square feet of meeting space. The Las Vegas Convention Center now has more than 3.2 million square feet of total space, and features approximately 2 million square feet of net exhibit space, and 380,000 square feet of net meeting room space, accommodating 170 meeting rooms with seating capacities from 20 to 7,500. In 2001, more than 4.0 million convention and trade show delegates traveled to Las Vegas, generating more than $4.8 billion in non-gaming revenue.

Shortly after the terrorist attacks of September 11, 2001, an estimated 12,000-15,000 gaming industry employees were laid off due to an expected decrease in tourism revenue. In October 2001, many of these employees were recalled, although some of them only on a part-time or on-call basis. Although tourist traffic is not back to its previous levels, an upward trend has been realized since early October 2001.

During 2001, firm and non-firm sales to wholesale customers comprised 39.1% of total energy sales, an increase of 310.0% over the prior year. Wholesale customers consist of other utilities or municipalities that sell power to end users, marketing entities and others that exchange power with NPC.

                                ==========      ======      =========      ======

NPC's increase in wholesale MWh sales from last year was a result of market conditions and NPC's power procurement activities. See Purchased Power Procurement in Item 7, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, for a discussion of the Utilities' purchased power procurement strategies.

Construction Program

NPC's construction program and estimated expenditures are subject to continuing review, and are revised from time to time due to various factors, including the rate of load growth, escalation of construction

costs, availability of fuel types, the number and status of proposed independent generation projects, the need for additional transmission capacity in southern Nevada, changes in environmental regulations, adequacy of rate relief, and NPC's ability to raise necessary capital.

Gross construction expenditures for 2001, including allowance for funds used during construction (AFUDC) and contributions in aid of construction, were 200.9 million, and for the period 1997 through 2001, were $1,155.6 million. Estimated construction expenditures for 2002 and the period from 2003 to 2006 are as follows (dollars in thousands):

The River Mountain Project is a 230kV (kilovolt) joint transmission project with the Colorado River Commission. Total project costs incurred through December 31, 2001, were approximately $34.0 million. Actual costs for 2001 were $7.7 million. This project was completed in 2001 and was in service in June of 2001.

The Centennial Plan was approved in NPC's 2001 Refiled Resource Plan. This plan, consistent with its tariff and FERC pricing policies, involves the following 500 kV lines (1) the Harry Allen substation to Crystal substation 500 kV lines, (2) the Harry Allen substation to Northwest substation 500 kV line, and (3) the Harry Allen substation to Mead substation 500 kV line. Additional facilities include a new 500 kV substation at Harry Allen, 500/230 kV transformer at Mead and Northwest substation, phase shifting transformer at Crystal substation, and several other sub-transmission upgrades and additions. Total estimated cost of the project is $296.2 million. Total project actual costs incurred through December 31, 2001, were $20.1 million. Estimated costs for 2002 are $131.1 million, which may be financed utilizing internally generated cash and/or the proceeds from various forms of debt. See Transmission, later, for additional information about the Centennial Plan.

Facilities and Operations

Total System

NPC maintains a wide variety of resources in its generation system. The availability of alternate resources allows NPC to dispatch its electric generation system in a more cost-effective manner under varying operating and fuel market conditions, while maintaining system integrity. NPC also supplies its customers' electric power needs using a combination of firm and interruptible resources to maximize operating flexibility, while minimizing cost. During 2001, NPC generated 33.9% of its total electric energy requirements in its own plants, purchasing the remaining 66.1% as shown below:

NPC's decision to purchase short-term and spot energy in lieu of its own generation is based on the economics of purchasing "as-available" energy when it is less expensive than its own generation.

NPC's 2001 company generation of 9,899,195 MWh is down 7.9% from NPC's 2000 company generation of 10,744,466 MWh due to decreased generation late in 2001 when the cost of purchased power was more economical than generation. NPC's 2001 purchased power of 19,268,305 MWh is up 99.5% from NPC's 2000 purchased power of 9,659,118 MWh.

Load and Resources Forecast

NPC's electric customer growth rate was 4.5% in 2001, 5.1% in 2000, and 5.9% in 1999. Retail electricity sales were 17.2 million MWh in 2001, which represents an increase of 2.4% over 2000 retail electricity sales of 16.8 million MWh. Wholesale electricity sales reached 11.1 million MWh in 2001, which represents an increase of 313% over 2000 wholesale electricity sales of 2.7 million MWh. Overall, annual system electricity sales reached 28.3 million MWh in 2001, which represents an increase of 45% over 2000 system electricity sales of 19.5 million MWh. The bulk of the 45% increase is attributed to wholesale sales. Changes in the wholesale market have dramatically increased the amount of purchases and sales of wholesale

power. See Purchased Power Procurement in Item 7, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, for a discussion of the Utilities' purchased power procurement strategies. NPC's peak electric demand rose to 4,412 MW in 2001 from 4,325 MW in 2000.

The forecasted peak energy demand for 2002 and 2003 below reflects, among others, five key assumptions:

. Southern Nevada experiences normal weather conditions, based on historical 20-year averages.

. No adjustments have been made to incorporate the potential loss of customers leaving for alternative providers under the provisions of AB 661 or Senate Bill 211, which allows the Colorado River Commission to sell electricity to its purveyors of water for water pumping electric-related loads only. However, four large commercial customers of NPC have filed an application under the provisions of AB 661 to procure energy from an alternative source other than the Utility and one large commercial customer has filed a letter of intent to file an application to procure energy from an alternative source. The combined peak load of AB 661 notice of intent customers and SB 211 eligible customers is less than 10% of NPC's retail load.

. Retail electric rates are set at the levels requested in NPC's most recent general and deferred energy rate case filings.

. The southern Nevada economy recovers from the effects of the September 11, 2001, terrorist attacks by the fourth quarter of 2002.

. Concerns over power outages in California subside by summer 2002 resulting in reduced conservation efforts by NPC's customers.

Sales and peak energy demand will vary from forecasted levels to the extent that actual experience varies from the above assumptions and to the extent that other factors affect sales and demand.

NPC's actual total system capability and peak loads for 2001, and as estimated for summer peak demand for 2002 and 2003 are shown below:

(1) The combined cycles at Clark Station each consist of one steam turbine and two combustion turbines for a total of six generating units.

(2) Reid Gardner Unit No. 4 is jointly owned by the California Department of Water Resources ("CDWR") (67.8%) and NPC (32.2%). NPC is the operating agent. Contractually, NPC is entitled to receive 24 MW of base load capacity and 226 MW of peaking capacity. NPC is entitled to use 100% of the unit's peaking capacity for 1,500 hours each year and is entitled to 9.6% of the first 250 MW of capacity and associated energy.

(3) This represents NPC's 11.3% undivided interest in the Navajo Generating Station as tenant in common without right of partition with five other non-affiliated utilities.

(4) This represents NPC's 14% undivided interest in the Mohave Generating Station as tenant in common without right of partition with three other non-affiliated utilities, less operating restrictions.

Purchased Power

NPC utilizes and maintains a diverse portfolio of resources with the objective of minimizing its net average system operating costs while providing reliable service. This portfolio consists of contracted and spot market supplies, as well as its own generation. During the past several years, including the first half of 2001, NPC experienced a dramatic increase in the market price of energy. Some of this increase reflects an overall increase in electricity costs throughout the country, the changing of regulatory environments, and the opening of new and/or deregulated markets. However, costs for contracted and spot market energy supplies fell dramatically in the second half of 2001 and limited NPC's ability to mitigate previous purchase power costs by selling any short-term excess energy because it limited the price at which NPC could sell surplus energy during market shortages. Some of NPC's purchased power contracts are also at price levels above which NPC is permitted to recover in current rates. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, for a discussion of deferred energy accounting and legislation.

NPC is a member of the Western Systems Power Pool and the Southwest Reserve Sharing Group (SRSG). NPC's membership in the SRSG has allowed it to network with other utilities in an effort to use its resources more efficiently in the sharing of responsibilities for reserves.

NPC purchases both forward firm energy (typically in blocks) and spot market energy based on economics, operating reserve margins and unit availability. NPC seeks to manage its growing loads efficiently by utilizing its generation resources in conjunction with buying and selling opportunities in the market.

NPC purchases Hoover Dam power pursuant to a contract with the State of Nevada which became effective June 1, 1987, and will continue through September 30, 2017. NPC's allocation of hydro-electric capacity is 235 MW.

NPC has a contract to purchase 222 MW from Nevada Sunpeak Limited Partnership, an independent power producer. The contract became effective June 8, 1991 and will continue through May 31, 2016.

According to the regulations of the PURPA, NPC is obligated, under certain conditions, to purchase the generation produced by small power producers and cogeneration facilities at costs determined by the appropriate state utility commission. Generation facilities that meet the specifications of the regulations are known as qualifying facilities (QFs). As of December 31, 2001, NPC had a total of 305 MW of contractual firm capacity under contract with four QFs. All QF contracts currently delivering power to NPC at long-term rates have been approved by the PUCN and have QF status as approved by the FERC. The QFs are as follows:

                                                         Net

Energy purchased by NPC from the QFs constituted 29.1% of the net purchased power requirements (excluding wholesale purchases), and 13.2% of the net system requirements during 2001. All of the QFs are cogenerators providing steam for various products and businesses.

Transmission

NPC's existing transmission lines are primarily confined within Clark County, Nevada. Four 230kV transmission lines connect NPC to the Western Area Power Administration's transmission facilities at Henderson and Mead Substations. Three 230 kV lines connect NPC to the Los Angeles Department of Water and Power's transmission facilities at McCullough Substation. A 345 kV line connects NPC to PacifiCorp at the Utah-Nevada state line. Also, NPC has two 500/230 kV transformers that connect NPC to the Navajo Transmission System at the Crystal Substation. Finally, NPC also has ownership rights in two 500 kV transmission lines that allow for the transmittal of NPC's share of power from its interests in the Mohave and Navajo Generating Stations to NPC's systems.

The River Mountain Project is a transmission project developed in partnership with the Colorado River Commission of Nevada that was placed in service in June 2001. NPC's portion of the project consists of two 230 kV transmission lines built along separate transmission corridors between the Mead Substation and NPC's new Equestrian Substation. In addition, to facilitate the ability to deliver power scheduled between Mead Substation and Equestrian Substation, NPC built a 230 kV transmission line between the Equestrian Substation and the Faulkner Substation. The project increased import capability by 350 MW. The completed project costs were approximately $34.0 million.

12

NPC received approval from the PUCN to construct two transmission projects proposed in NPC's 2001 Refiled Resource Plan. The Faulkner Substation to Tolson Substation 230 kV project and the Tolson Substation to Arden Substation 230 kV upgrade project are both internal, NPC reinforcements with 2003 and 2004 in-service dates, respectively. Due to independent power producer (IPP) transmission service requests, the Arden-Tolson 230 kV upgrade project will be advanced one year for an in-service date of June 2003. The Faulkner-Tolson 230 kV project will increase NPC's import capability by 300 MW. The total estimated project costs are $8.29 million.

Due to the supply shortage in the western United States, several IPP's have proposed the construction of new generating plants in southern Nevada, and have requested transmission service from NPC. NPC has committed to construct this transmission infrastructure in furtherance of its on-going business plan. NPC has proposed the Centennial Plan to address transmission service requests from these IPP's. The Centennial Plan was approved in NPC's 2001 Refiled Resource Plan. This plan, consistent with its tariff and FERC pricing policies, involves the following lines (1) the Harry Allen substation to Crystal substation 500 kV line, (2) the Harry Allen substation to Northwest substation 500 kV line, (3) the Harry Allen substation to Mead substation 500 kV line and (4) Two Bighorn-Arden 230 kV lines. Additional facilities include a new 500 kV substation at Harry Allen, 500/230 kV transformers at Mead and Northwest substation, a phase shifting transformer at Crystal substation, and several other sub-transmission upgrades and additions.

For a discussion of the change in fuel costs, see Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

Coal delivered to the Reid Gardner Station originates from various mines in the Utah coalfields and is delivered to the station via the Union Pacific Railroad. Partial requirements for coal supplies are under contract for various terms up to 2007, with the remainder of 2001's requirements purchased from the spot market under four one-year contracts. NPC's long-term coal supply agreement with RAG Coal Sales of America, Inc. is supplied from its Willow Creek Mine in Carbon County, Utah, which experienced an explosion and fire on July 31, 2000, and is currently under an ongoing force majeure. No deliveries under this agreement were scheduled for 2001 and NPC replaced these volumes with spot market purchases.

13

The mine remains sealed and NPC does not anticipate that deliveries will resume before the contract terminates.

The Union Pacific Rail Transportation contract provides for deliveries from the Provo, Utah interchange as well as various mines in the Price, Utah area to the Reid Gardner Station in Moapa, Nevada. This contract was effective January 1, 1996 and has been extended through December 31, 2004. The Utah Railway contract originates the remainder of NPC's Price, Utah area supplies. This contract has been extended through December 31, 2002. All of NPC's rail transportation contracts contain certain tonnage requirements and railroad service criteria.

Coal for both the Mohave and Navajo Stations is obtained from surface mining operations conducted by Peabody Coal Company on portions of the Black Mesa in Arizona within the Navajo and Hopi Indian reservations. The supply contracts with Peabody extend to December 31, 2005 for Mohave and to June 1, 2011 for Navajo, each contract having an option to extend for an additional 15 years.

NPC purchases natural gas on a firm, fixed and indexed price basis from the Rocky Mountain, San Juan or Permian Supply Basins.

Natural gas is transported to the Clark and Sunrise stations via El Paso Natural Gas Company from the San Juan and Permian Basins and by Kern River Gas Transmission Company from the Rocky Mountain Basin. NPC has entered into a summer seasonal transportation contract for 50,000 decatherms (Dth)/day and an annual contract for 75,000 Dth/day of Kern River Pipeline capacity. This service is scheduled for delivery in May 2003 and will run for a period of 15 years. NPC also responded to an open season for shorter term service in the Kern River California Emergency Expansion and was awarded 29,600 Dth/day for the period July 2001 to April 2002 and 5,600 Dth/day for the period May 2002 to April 2003. The Emergency Expansion service does not carry any renewal rights.

Local natural gas transportation service to Clark and Sunrise Stations is provided under a 32-year transportation services contract with Southwest Gas Company signed in 1995. This contact provides firm service and contains certain operating and nominating provisions. The Harry Allen Station is directly connected to Kern River Pipeline.

Oil provides a secondary fuel for Clark, Sunrise and Harry Allen Stations and is used in the igniters at Reid Gardner.

SIERRA PACIFIC POWER COMPANY

SPPC is a Nevada corporation organized in 1965 as a successor to a Maine corporation organized in 1912. SPPC became a wholly owned subsidiary of Sierra Pacific Resources on May 31, 1984. Its mailing address is Post Office Box 10100 (6100 Neil Road), Reno, Nevada 89520-0024.

SPPC is a public utility primarily engaged in the distribution, transmission, generation, purchase and sale of electric energy. It provides electricity to approximately 315,000 customers in a 50,000 square mile service area in western, central and northeastern Nevada, including the cities of Reno, Sparks, Carson City, Elko, and a portion of eastern California, including the Lake Tahoe area. In 2001, electric revenues were 90.6% of SPPC's revenue.

14

SPPC also provides natural gas service in Nevada to approximately 119,500 customers in an area of about 600 square miles in Reno/Sparks and environs. In 2001, natural gas revenues were 9.4% of SPPC's revenues.

On June 11, 2001, SPPC completed the sale of its water business to the Truckee Meadows Water Authority (TMWA) for $341 million. SPPC recorded a $25.8 million gain on the sale, net of income taxes of $18.2 million. Transfer of the hydroelectric facilities included in the contract of sale for an additional $8 million will require action by the California Public Utility Commission (CPUC). The sale agreement contemplates a second closing for the hydroelectric facilities to accommodate the CPUC's review of the transaction. See "Sale of Water Business," later, for further discussion.

SPPC has three primary, wholly owned subsidiaries: GPSF-B, Pinon Pine Corp. (PPC) and Pinon Pine Investment Co. (PPIC). GPSF-B, PPC and PPIC, collectively, own Pinon Pine Company, L.L.C., which was formed to take advantage of federal income tax credits available under (S)29 of the Internal Revenue Code associated with the alternative fuel (syngas) produced by the coal gasifier located at the Pinon Pine facility. (See Note 5 to the Financial Statements.)

Business and Competitive Environment

In 2001, SPPC's electric business contributed $1,399 million (90.6%) in revenues from continuing operations. The electric system peak typically occurs in the summer, while the winter peak runs nearly as high. The system has an annual load factor of approximately 71%, which is higher than the industry norm of 50% to 55%.

Winter peak loads are primarily driven by increased demand for space heating, demand for air movement (with forced air gas and oil furnaces), and ski resort demands (hotels, lifts, etc.). Summer peak loads are primarily driven by cooling equipment demand (including air conditioning demand) and irrigation pumping. SPPC's peak load increased an average of 4.6% annually over the past five years, reaching 1,529 MW on August 7, 2001. SPPC's total electric MWh sales have increased an average of 10.3% annually over the past five years. The mining and wholesale sectors comprise the majority of this growth.

SPPC's electric customers by class contributed the following toward 2001 and 2000 MWh sales:

                                                                           MWh Sales

According to the Nevada Division of Minerals, the State led the nation in the production of gold in 2001, as it has for many years. Nevada's gold production in 2001 reached 8.1 million ounces. However, in 2001 the industry continued to be challenged by low gold prices and numerous financial, environmental, and regulatory hurdles. It responded to these pressures by continuing to pursue mergers and consolidations, streamlining

15

operations, cutting overhead costs, and closing down less efficient and uneconomic properties. These actions led to SPPC seeing a small decrease in total MWh sales to the mining industry during 2001.

SPPC has long-term power sales agreements with seven of its major mining customers for terms ranging from 5 to 15 years. The final contract expires in 2011. These agreements secure over 265 MW of present and future mining load, or approximately $96 million in annual revenues, which is 6.9% of 2001 electric operating revenues. The agreements require that customers maintain minimum demand and load factor levels, and include termination charge provisions to recover all of SPPC's customer-specific facilities investment.

The resorts and recreation customer segment consists of hotels, casinos and ski resorts which comprise 5.4% of the total electric system retail MWh sales. Overall MWh sales are slightly down from 2000 due to implementation of energy conservation efforts at most of the large casino hotels and a winter that has provided an increase in precipitation. The snowfall has decreased the need for the ski resorts to use their snowmaking equipment which is a large component of their energy consumption.

Tourism and gaming were affected by the decrease in flight schedules and the economy downturn last September. Northern Nevada casinos have also seen some impact from Indian gaming in northern California. Though the tourism and gaming segment faced challenges in 2001, northern Nevada continues to be a strong player in the entertainment industry. Northern Nevada casino hotels are continuously focusing on competitive strategies by packaging entertainment value, customer comfort and reasonable pricing with the natural attraction of the Sierra Nevada geographical location which has proven to be a successful model. Many of the larger casinos have also remodeled their facilities to provide for an increased demand for conventions.

The manufacturing and warehousing customer segment overall continues to grow at a steady pace. Several manufacturing customers have suffered large order reductions and production losses due to the economic slowdown, which has had an impact on the rapid growth projections. At the same time, there has been growth in the sector as the result of manufacturers relocating out of the California market and expanding their Nevada presence. Northern Nevada continues to show promise as a destination of choice for the high-technology industry, which should result in a continued increase in sales to the manufacturing and warehousing customer segment. In 2001, SPPC solidified working relationships within the business community recruiting industries in targeted sectors such as plastic manufacturers and hi-technology companies.

The 2001 session of the Nevada State legislature saw the passage of AB 661. One provision of this bill allows commercial customers with an average annual load of one megawatt or more to file a letter of intent and application with the PUCN to buy electricity from another provider beginning in mid-2002. This provision was part of a package of legislation passed by the 2001 Legislature to ensure the continued creditworthiness of the Utilities and protect consumers from unexpected rate hikes. During 2001, a number of SPPC's large commercial customers indicated they would be filing applications to pursue alternative supplier options. See Regulation and Rate Proceedings in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations for further discussion.

SPPC's MWh sales to wholesale customers have increased 14.1% over the past year. During 2001, firm and non-firm sales to wholesale customers comprised 32.1% of total energy sales. Wholesale customers consist of other utilities or municipalities that sell power to end users, marketing entities and others that exchange power with SPPC.

SPPC's increase in wholesale MWh sales from last year was a result of market conditions and SPPC's power procurement activities. See Purchased Power Procurement in Item 7, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, for a discussion of the Utilities' purchased power procurement strategies.

Construction Program

SPPC's construction program and estimated expenditures are subject to continuing review, and are revised from time to time due to various factors, including the rate of load growth, escalation of construction costs, availability of fuel types, the number and status of proposed independent generation projects, the need for additional transmission capacity in northern Nevada, changes in environmental regulations, adequacy of rate relief, and SPPC's ability to raise necessary capital.

Gross construction expenditures for 2001, including AFUDC and contributions in aid of construction, were $133.6 million, and for the period 1997 through 2001, were $762.4 million. Estimated construction expenditures for 2002 and the period 2003-2006 are as follows (dollars in thousands):

As a supplement to its own internal generation, SPPC purchases both firm and non-firm energy to meet its customer demand requirements. See Purchased Power Procurement in Item 7, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, for a discussion of the Utilities' purchased power procurement strategies. In 2001, most of SPPC's non-utility generation came from QFs, except for 21,730 MWh, which came from two small power producers.

Load and Resources Forecast

SPPC's electric customer growth rate was 1.9% in 2001, 2.6% in 2000, and 2.6% in 1999. Annual retail electricity sales were 8.7 million MWh in 2001, which represents a decrease of 1% compared to 2000 retail electricity sales of 8.8 million MWh. Annual wholesale electricity sales reached 4.1 million MWh in 2001, which represents an increase of 14% over 2000 wholesale electricity sales of 3.6 million MWh. Overall, annual system electricity sales reached 12.9 million MWh in 2001, which represents an increase of 3.5% over 2000 system electricity sales of 12.4 million MWh. The 2001 peak electric demand was 1,529 MW compared to a weather-adjusted peak of 1,531 MW for 2000. The lack of growth in the peak is mainly attributable to demand-reduction efforts by customers due to the power issues in the West.

The forecasted peak energy demand for 2002 and 2003 below reflects, among others, five key assumptions:

. Northern Nevada experiences normal weather conditions, based on historical 20-year averages.
. No adjustments have been made to incorporate the potential loss of customers leaving for alternative providers under the provisions of AB661. However, one large commercial customer of SPPC has filed an application under the provisions of AB 661 to procure energy from an alternative source other than the Utility. The customer, SPPC, and PUCN staff are negotiating a stipulation regarding settlement of the terms and conditions under which this customer will be permitted to procure energy from an alternative source other than SPPC. The terms and conditions of the stipulation are expected to comply with the provisions of AB 661 in that SPPC and

19

its remaining customers will not be negatively impacted by the customer's departure. A hearing on the stipulation has been set for March 20, 2002.
. Retail electric rates are set at the levels requested in SPPC's most recent general and deferred energy rate case filings.
. SPPC continues to be a summer peaking utility.
. Concerns over power outages in California subside by summer 2002 resulting in reduced conservation efforts by SPPC's customers.

Sales and peak energy demand will vary from forecasted levels to the extent that actual experience varies from the above assumptions and to the extent that other factors affect sales and demand.

SPPC's actual total system capability and peak loads for 2001, and as estimated for summer peak demand for 2002 and 2003 are shown below:

SPPC plans its system capacity needs in accordance with the WSCC reliability criteria, which recommends planning reserves in excess of required operating reserves. "Additional Required" represents the additional, uncommitted capacity needed in order to maintain adequate reserve margin consistent with the WSCC planning reserve criteria. These additional reserves will be met, if needed, with short-term purchases through 2003 to the extent available. At the time of the 2001 system peak, SPPC had purchased firm capacity

20

under long-term contracts with other utilities and qualifying facilities equal to 10% of total peak hour capacity. Short-term firm block purchases comprised 26% of the peak, with no economy (non-firm) purchases transacted (only firm power purchases).

(1) SPPC is the operator and owns an undivided 50 percent interest in the Valmy plant. Idaho Power Company owns the remainder. The capacities shown above for the Valmy plant represent SPPC's share only. SPPC owns 100 percent of all of its remaining electric generation plants.

(2) Pinon is part of the Pinon Pine Integrated Coal Gasification Combined Cycle power plant. This project was part of the Department of Energy's Clean Coal Demonstration Program. Although the coal gasification portion of the facility is in the start-up phase, the unit has been operating on natural gas since 1996.

(3) The combined cycle at Pinon consists of one combustion turbine and one steam turbine.

(4) The 4 hydro generating units were to be included in the sale of SPPC's water business in June 2001. However, the California Legislature has mandated that the sale of these units (as well as any other units serving California markets) be postponed until 2006 due to uncertainty in the California power markets. See sale of Water Business, later.

Purchased Power

SPPC continues to manage a diverse portfolio of contracted and spot market supplies, as well as its own generation, with the objective of minimizing its net average system operating costs. During 2001, SPPC experienced a dramatic increase in the price of market energy compared to previous years. Some of this increase is reflective of the overall increase in electricity costs throughout the western United States. See Industry and Regional Problems Affecting the Utilities, earlier. Some of SPPC's purchased power contracts are at price levels above which SPPC is permitted to recover in current rates. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, for a discussion of deferred energy accounting and legislation.

SPPC is a member of the Northwest Power Pool and Western Systems Power Pool. These pools have provided SPPC further access to spot market power in the Pacific Northwest and the Southwest. In turn, SPPC's generation facilities provide a backup source for other pool members who rely heavily on hydroelectric systems.

SPPC purchases hydroelectric and thermal generation spot market energy, by the hour, based upon economics and system import limits. Also purchased during peak load periods is firm energy as required to supply load and maintain adequate operating reserve margins. As off-system energy costs increase, SPPC

21

supplies a higher percentage of its native load utilizing its fossil fuel generation but is still required to buy peaking energy from the market.

Currently, SPPC has contracted for a total of 75 MW of long-term firm purchased power from the utility supplier listed below. SPPC's firm purchase power contract contains minimum purchase obligations. Meeting these minimums has not been a problem for SPPC in the past, and is not expected to be a problem in the future.

                               Contract     Operation     Termination      Minimum

 PacifiCorp                      75 MW      June 1989    Feb 28, 2009        70%

According to PURPA, SPPC is obligated, under certain conditions, to purchase the generation produced by small power producers and co-generation facilities at costs determined by the appropriate state utility commission. Generation facilities that meet the specifications of the regulations are known as qualifying facilities. As of December 31, 2001, SPPC had a total of 109 MW of maximum contractual firm capacity under 15 contracts with QFs. SPPC also had contracts with three projects at variable short-term avoided cost rates. All QF contracts currently delivering power to SPPC at long-term rates have been approved by either the PUCN or the California Public Utility Commission (CPUC), and have QF status as approved by the FERC. One long-term QF contract terminates in 2006, one terminates in 2039, and the rest terminate between 2014 and 2022.

Energy purchased by SPPC from QFs constituted 8.8% of the net system requirements (excluding wholesale purchases) during 2001. These contracts continue to provide useful diversity for SPPC in meeting its peak load. All the QFs from which SPPC makes firm purchases are either geothermal (87%), hydroelectric or biomass.

The actual QF firm capacity output under contract was 64 MW during the summer of 2001. The actual QF output for all non-utility generator deliveries during the summer 2001 peak was 93 MW

Transmission

SPPC's existing transmission lines extend some 300 miles from the crest of the Sierra Nevada in eastern California, northeast to the Nevada-Idaho border at Jackpot, Nevada, about 160 miles from Reno northwest to Alturas, California, and 250 miles from the Reno area south to Tonopah, Nevada. A 230 kV transmission line connects SPPC to facilities near the Utah-Nevada state line, which in turn interconnects SPPC to Utah Power facilities. A 345 kV transmission line connects SPPC to Idaho Power facilities at the Idaho-Nevada state line. A 345 kV line connects SPPC to the Bonneville Power Administration's facilities near Alturas, California.

SPPC also has two 120 kV lines and one 60 kV line that interconnect with Pacific Gas & Electric on the west side of SPPC's system at Donner Summit, California. Two 60 kV transmission ties allow wheeling of up to 14 MW of power from the Beowawe Geothermal Project, which is located within SPPC's service area, to Southern California Edison. These two minor interties are available for use during emergency conditions affecting either party. The transmission intertie system provides access to regional energy sources.

The Falcon to Gonder Project is a 185-mile 345 kV line connecting SPPC's Falcon Substation to Mt. Wheeler Power's Gonder Substation. The Falcon to Gonder Project improves system import and export capabilities and enables SPPC to provide transmission service between Idaho, Utah, and the northwest. The Final Environmental Impact Statement was released in December 2001. Federal permitting is expected to be completed by the end of March 2002, with construction starting in May 2002. SPPC has ordered long lead material like towers and transformers, and is preparing to start the construction bid process. The project in-

22

service date is June 2003. Total project costs incurred through December 31, 2001, were $11.5 million. Actual costs incurred in 2001 were $5.9 million. Estimated costs for 2002 are $54.5 million.

See Regulation and Rate Proceedings, FERC Matters in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations for a discussion of regional transmission issues.

Fuel Availability

SPPC's 2001 fuel requirements for electric generation were provided by natural gas, coal, and oil. The average costs of coal, gas and oil for energy generation per MMBtu for the years 1997-2001, along with the percentage contribution to total fuel requirements, are as follows:

SPPC's long-term contract with Black Butte Coal Company for coal shipments to Valmy from the mine near Rock Springs, Wyoming, remains in effect until June 30, 2007, or until all volume requirements under the contract are delivered and/or cancelled. Due to previous accelerated purchases and cancellations, and continuing cancellations of minimum monthly volume obligations, SPPC fully satisfied all volume requirements and termination of the contract occurred in February 2002.

SPPC's long-term coal contract with Canyon Fuel Company, LLC (Canyon), which provides coal for Valmy from Canyon's SUFCO mine in Central Utah, expires on June 30, 2003. This contract also contains minimum volume requirements that SPPC expects to meet each year until termination. The current owner of the SUFCO mine is Arch Coal, Inc., which acquired ARCO Coal (the previous owner of the Canyon properties, including SUFCO) on June 1, 1998.

During 2001, two short-term agreements for the purchase of spot market coal were in place. The source of this coal is the Uinta Basin of Utah. These spot market purchases supplement base volume requirements under SPPC's long-term coal contracts at a cost approximately one-half that of contract coal.

As of December 31, 2001, Valmy's coal inventory level was 378,011 tons, or approximately 65 days of consumption at 100% capacity. Inventory levels were increased to allow for economically priced supplies under contract to be delivered prior to the expiration of those supply arrangements.

During 2001, transportation of coal to Valmy was provided by the Union Pacific Railroad (UP) under a 3-year agreement effective June 1, 1998. The agreement was extended an additional 3.5 years and will now expire December 31, 2004.

During 2001, SPPC operated the Pinon Pine facility exclusively on natural gas. No coal was purchased in 2001 for synthetic gas production in the plant's coal gasification facility.

23

SPPC meets its needs for residual oil for generation through purchases on the spot market. During portions of 2001, oil prices were significantly lower than natural gas prices. Additional oil supply was ordered for consumption and to ensure the ability of the electric division to make gas available to SPPC's natural gas business on peak days. The actual residual oil inventory level at these two sites was 318,000 barrels as of December 31, 2001, which is equal to a 14-day supply at full load operation.

Natural Gas Business

SPPC's natural gas business consists of operating the local distribution company (LDC) for the Reno/Sparks metropolitan area and procuring gas for electrical power generation at the Tracy and Ft. Churchill plants. The LDC accounted for $145.7 million in 2001 operating revenues or 9.4% of SPPC's revenues from continuing operations. Growth in SPPC's LDC service territory continues to be strong. Customer meter count growth during 2001 was 4.7%. SPPC's total customer meter count increased by 5,446 to 121,862 meters by the end of 2001.

Growth in all sectors is expected to continue as new developments in SPPC's distribution service area are planned. SPPC's forecast for growth in the number of LDC customers in 2002 is: residential 4.8%, small commercial 2.5%, and large commercial 5.5%.

SPPC's natural gas LDC business is subject to competition from other suppliers and other forms of energy available to its customers. Large customers with fuel switching capability compare natural gas prices on an interruptible basis to alternative energy source prices. Additionally, large customers have the ability to secure their own gas supplies; however, through 2000 and 2001, large customers that were securing their own supplies generally found that receiving gas from SPPC's LDC was more reliable and more economical than securing their own supplies. At the end of 2001, only two large customers were still securing their own supplies.

To secure gas supplies for power generation and the LDC, SPPC contracted for firm winter-only and annual gas supplies with 10 Canadian and domestic suppliers to meet the firm requirements of its LDC and electric operations. The winter period contracts totaled 160,000 Dth per day through March 2001, and the summer period contracts totaled 115,000 Dth per day for April through October 2001.

SPPC's firm natural gas supply is supplemented with natural gas storage services and supplies from a Northwest Pipeline Co. facility located at Jackson Prairie in southern Washington and liquefied natural gas (LNG) storage from a facility located near Lovelock, Nevada. The LNG facility is operated by Paiute Pipeline Company and is used for meeting peak demand. The Jackson Prairie and LNG facilities can contribute a total of approximately 48,000 Dth per day of peaking supplies.

In November 1996, SPPC entered an agreement to sell winter seasonal peaking capacity supplies to another company over a seven-year period. The contract provides for the payment to SPPC of a monthly reservation charge, reimbursement of pipeline capacity charges during the winter, and a volumetric commodity charge based on the market price for natural gas. SPPC was able to enter into this agreement due to the ability of its power plants to utilize alternative fuels and its power importation option.

Following is a summary of the transportation and approximate storage capacity of SPPC's current gas supply program for 2001 (for the twelve months period ending October 31, 2002). Firm transportation capacity on the Northwest/Paiute system exists to serve primarily the LDC. Firm transportation capacity on the PGT/Tuscarora system exists primarily to serve SPPC's electric generating plants. Storage capacity is generally used for the peaking requirements of the LDC.

Total LDC Dth supply requirements in 2000 and 2001 were 13.2 million Dth and 14.26 million Dth, respectively. Electric generating fuel requirements for 2001 and 2000 were 28.96 million Dth and 38.6 million Dth, respectively.

In January 2001, the PUCN approved a Purchase Gas Adjustment filing from the previous year and the new rates became effective February 1, 2001. An average residential customer had an increase in their rates of approximately 35%. In November 2001, the PUCN approved another Purchase Gas Adjustment filing. An average residential customer had an increase in their rate of approximately 25%. Each of these approvals reflects complete recovery of the LDC's gas purchases.

As of December 31, 2001, SPPC owned and operated 1,601 miles of three-inch equivalent natural gas distribution piping, 108 miles of which were added in 2001. Also during 2001, Tuscarora Gas completed construction of a lateral gas transmission line to a new SPPC high-pressure regulator station (completed in 2000). The lateral transmission line connected Tuscarora's primary transmission line to SPPC's LDC north of Reno in the Stead, Nevada area. The line provided the LDC the ability to receive more supply and exercise more operating flexibility. In 2001, SPPC completed several smaller system improvement projects. A small propane system that SPPC owns and operates was connected to the new Tuscarora Gas lateral line and converted to a natural gas system. Over 4 miles of 12" diameter main was added to the system, which improved the capacity and reliability in the southwest Reno area.

Sale of Water Business

On June 11, 2001, SPPC closed the sale of its water business to the Truckee Meadows Water Authority (TMWA) for $341 million. SPPC recorded a $25.8 million gain on the sale, net of income taxes of $18.2 million. Pursuant to a stipulation entered into in connection with the sale and approved by the PUCN, SPPC is required to refund to customers $21.5 million of the proceeds from the sale. The refund is being credited on the electric bills of SPPC's former water customers over a period not to exceed fifteen months from June 11, 2001.

Under a service contract with TMWA, SPPC will provide, on an interim basis, customer service, billing, and meter reading services to TMWA. Transfer of the hydroelectric facilities included in the contract of sale for an additional $8 million will require action by the CPUC. The sale agreement contemplates a second

25

closing for the hydroelectric facilities to accommodate the CPUC's review of the transaction. Not included in the sale were certain properties along the Truckee River related to the hydroelectric facilities and in California at Independence Lake. SPPC will continue to own this property with the intent of a possible future sale.

Regulation and Rate Proceedings

See Regulation and Rate Proceedings in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

GENERATION DIVESTITURE (NPC AND SPPC)

As a condition to its approval of the merger between SPR and NPC, the PUCN required the Utilities to file a Divestiture Plan for the sale of their electric generation assets. The PUCN approved a revised Divestiture Plan stipulation in February 2000. In May 2000 an agreement was announced for the sale of NPC's 14% undivided interest in the Mohave Generating Station ("Mohave"). In the fourth quarter of 2000 the Utilities announced agreements to sell six additional bundles of generation assets described in the approved Divestiture Plan. The sales were subject to approval and review by various regulatory agencies.

AB 369, which was signed into law on April 18, 2001, prohibits until July 2003 the sale of generation assets and directs the PUCN to vacate any of its orders that had previously approved generation divestiture transactions. In January 2001, California enacted a law that prohibits until 2006 any further divestiture of generation properties by California utilities, including SPPC, and could also affect any sale of NPC's interest in Mohave after July 2003 since the majority owner of that project is Southern California Edison. In addition, SPPC's request for an exemption from the requirements of a separate California law requiring approval of the CPUC to divest its plants was denied, subject to future refiling.

The sales agreements for the six bundles provide that they terminate eighteen months after their execution unless the parties agree to an earlier termination. The parties may extend the termination another six months to obtain additional regulatory approvals. As a result of the legislative and regulatory developments which have rendered the contracts impossible to perform, the Utilities are engaged in discussions with the buyers of the generation assets regarding the formal termination of the sales agreements and the related energy buyback contracts and interconnection agreements. As of December 31, 2001, the Utilities had incurred costs of approximately $12.3 million and $15.5 million, respectively, in order to prepare for the sale of generation assets. The Utilities have requested recovery of these costs in each Utility's respective general rate case filing with the PUCN, discussed in Regulation and Rate Proceedings, in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operation.

PORTLAND GENERAL ELECTRIC ACQUISITION

On April 26, 2001, SPR and Enron Corp. announced that they had mutually agreed to terminate their agreement for SPR's purchase of Enron's wholly owned subsidiary, Portland General Electric (PGE). In negotiating the mutual termination, SPR agreed to share certain expenses that Enron Corp and PGE had incurred for the proposed transaction. The Consolidated Statement of Income of SPR for the year ended December 31, 2001, reflects a charge in connection with the planned purchase of PGE of $22 million, including approximately $7.5 million representing a termination payment for shared expenses.

ENVIRONMENT (SPR, NPC AND SPPC)

As with other utilities, NPC and SPPC are subject to federal, state and local regulations governing air, water quality, hazardous and solid waste, land use and other environmental considerations. Nevada's Utility Environmental Protection Act requires approval of the PUCN prior to construction of major utility, generation

26

or transmission facilities. The United States Environmental Protection Agency (EPA), Nevada Division of Environmental Protection (NDEP), and Clark County Health District (CCHD) administer regulations involving air quality, water pollution, solid, hazardous and toxic waste. SPR's Board of Directors has a comprehensive environmental policy and separate board committee that oversees NPC, SPPC, and SPR's corporate performance and achievements related to the environment.

Nevada Power Company

The Grand Canyon Trust and Sierra Club filed a lawsuit in the U.S. District Court, District of Nevada, in February 1998, against the owners (including NPC) of the Mohave Generation Station ("Mohave"), alleging violations of the Clean Air Act regarding emissions of sulfur dioxide and particulates. An additional plaintiff, National Parks and Conservation Association, later joined the suit. The plant owners and plaintiffs have had numerous settlement discussions and filed a proposed settlement with the court in October 1999. The consent decree, approved by the court in November 1999, established emission limits for sulfur dioxide and opacity and required installation of air pollution controls for sulfur dioxide, nitrogen oxides and particulate matter. The new emission limits must be met by January 1, 2006 and April 1, 2006 for the first and second units respectively. However, if the owners sell their entire ownership interest with a closing date prior to December 30, 2002, the new emission limits become effective 36 months and 39 months from the date of last closing for the two respective units. The estimated cost of new controls is $395 million. As a 14% owner in the Mohave Station, NPC's cost could be $55 million.

Also, the United States Congress authorized the EPA to study the potential impact Mohave may have on visibility in the Grand Canyon area. A final report of the study results was released in March 1999. The study acknowledges that sulfur dioxide emissions from Mohave are transported to the Grand Canyon. The EPA has solicited information to determine whether visibility impairment in the Grand Canyon can be reasonably attributed to Mohave. The EPA determined that significant visibility impairment to the Grand Canyon cannot be reasonably attributable to the station provided controls are installed as agreed to in the consent order. Therefore, the EPA will not require a Best Available Retrofit Technology Review. Provisions that were agreed to in the settlement will be reflected in the state Implementation Plan for Nevada.

In May 1997, NDEP ordered NPC to submit a plan to eliminate the discharge of Reid Gardner Station wastewater to groundwater. The NDEP order also required a hydrological assessment of groundwater impacts in the area. In June 1999, NDEP determined that wastewater ponds had degraded groundwater quality. In August 1999, NDEP issued a discharge permit to Reid Gardner Station and an order that requires all wastewater ponds to be closed or lined with impermeable liners over the next 10 years. This order also required NPC to submit a Site Characterization Plan to NDEP to ascertain impacts. This plan is under review by NDEP. After approval, an estimate of remediation costs will be determined by NPC. New pond construction and lining costs are estimated at $15 million.

Also, at the Reid Gardner Station, the NDEP has determined that there is additional groundwater contamination that resulted from oil spills at the facility. NDEP has required submitting a corrective action plan. The extent of contamination has been determined and remediation is occurring at a modest rate. An engineering evaluation of the current remediation technology will occur in 2002 to verify efficiency and to expedite remediation. Remediation modifications are not expected to materially affect the financial position of SPR or NPC.

In May 1999, NDEP issued an order to eliminate the discharge of NPC's Clark Station wastewater to groundwater. The order also required a hydrological assessment of groundwater impacts in the area. This assessment, submitted to NDEP in February 2001, warranted a Corrective Action Plan which was submitted to NDEP in November and is pending review. Remediation costs are expected to be in the $500,000 - $750,000

27

range. In addition to remediation, NPC will spend $789,000 to line existing ponds. After review and approval of the Corrective Action Plan by NDEP, NPC will implement remediation.

In July 2000, NPC received a request from the EPA for information to determine the compliance of certain generation facilities at the Clark Station with the applicable State Implementation Plan. In November 2000, NPC and the Clark County Health District entered into a Corrective Action Order requiring, among other steps, capital expenditures at the Clark Station totaling approximately $3 million. In March 2001, the EPA issued an additional request for information that could result in remediation beyond that specified in the November 2000 Corrective Action Order. If the EPA prevails, capital expenditures and temporary outages of four of Clark Station's generation units could be required. Additionally, depending on the time of year that the compliance activity and corresponding generation outage would occur, the incremental cost to purchase replacement energy could be substantial.

Sierra Pacific Power Company

In September 1994, Region VII of EPA notified SPPC that it was being named as a potentially responsible party (PRP) regarding the past improper handling of Polychlorinated Biphenyls (PCBs) by PCB Treatment, Inc., located in Kansas City, Kansas, and Kansas City, Missouri (the Sites). The EPA is requesting that SPPC voluntarily pay an undefined, pro rata share of the ultimate clean-up costs at the Sites. A number of the largest PRP's formed a steering committee, which is chaired by SPPC. The responsibility of the Committee is to direct clean-up activities, determine appropriate cost allocation, and pursue actions against recalcitrant parties, if necessary. The EPA issued an administrative order on consent requiring signatories to perform certain investigative work at the Sites. The steering committee retained a consultant to prepare an analysis regarding the Sites. The Site evaluations have been completed. EPA is developing an allocation formula to allocate the remediation costs. SPPC has recorded a preliminary liability for the Sites of $650,000 of which approximately $136,000 has been spent through December 31, 2001. Once evaluations are completed, SPPC will be in a better position to estimate and record the ultimate liabilities for the Sites.

Other Subsidiaries of SPR

LOS, a wholly owned subsidiary of SPR, owns property in North Lake Tahoe, California, which is leased to independent condominium owners. The property has both soil and groundwater petroleum contaminate resulting from an underground fuel tank that has been removed from the property. Additional contaminate from a third party fuel tank on the property has also been identified and is undergoing remediation. Estimated future remediation costs are not expected to be significant.

NEICO, a wholly owned subsidiary of SPR, owns property in Wellington, Utah, which was the site of a coal washing and load out facility. The site now has a reclamation estimate supported by a bond of $4 million with the Utah Division of Oil and Gas Mining. The property was under contract for sale and the contract required the purchaser to provide $1.3 million in escrow towards reclamation. However, the sales contract was terminated and NEICO took title to the escrow funds. In September 2000, NEICO leased the property together with an option to purchase. It is NEICO's intention to either lease or sell the property.

OTHER SUBSIDIARIES OF SIERRA PACIFIC RESOURCES

Tuscarora Gas Pipeline Company

TGPC was formed as a wholly owned subsidiary in 1993 for the purpose of entering into a partnership (Tuscarora Gas Transmission Company or TGTC) with a subsidiary of TransCanada to develop, construct and operate a natural gas pipeline to serve an expanding gas market in Reno, northern Nevada, and northeastern California. In December 1995, TGTC completed construction and began service on its 229-mile pipeline

28

extending from Malin, Oregon to Reno, Nevada. TGTC interconnects with PG&E Gas Transmission - Northwest (GT-NW) at Malin, Oregon. GT-NW is a major interstate natural gas pipeline extending from the U.S./Canadian border, at a point near Bonners Ferry, Idaho to the Oregon/California border. The GT-NW system provides TGTC customers access to natural gas reserves in the Western Canadian Sedimentary basin, one of the largest natural gas reserve basins in North America. As of December 31, 2001, SPR had an investment of approximately $14.6 million in this subsidiary.

As an interstate pipeline, TGTC provides only transportation service. SPPC was the largest customer of TGTC during 2001, contributing 80% of revenues. Malin, Oregon began taking service from TGTC during October 1996. The Sierra Army Depot at Herlong, California began taking service from TGTC in October 1997. In 1998, TGTC began serving two new customers, the United States Gypsum Company located north of Empire, Nevada, and HL Power Company located northwest of Wendel, California.

In 2000, TGTC began construction on a 14.2-mile lateral, creating a new city gate connection into the SPPC distribution system. The lateral was completed and placed in service January 29, 2001, providing SPPC with an additional 10,000 Dth per day of firm transportation capacity in January 2001 and 5,661 Dth in November 2001. Also in 2000, TGTC surveyed shipper interest in the feasibility of an expansion of transportation capacity. This survey established that 95,912 Dth per day of new capacity would be required to meet the needs of existing and new shippers for the 2002-2003 winter heating season. Facilities required in Nevada would be approximately 14.2 miles of 20" diameter pipe and one 600 HP booster unit, and in California, three compressor stations each with a 6,000 HP turbine and related facilities. On January 30, 2002, the FERC approved the plans to expand the interstate gas pipeline owned by the Tuscarora Gas Transmission Company. The project will increase the pipeline's capacity by 74% and will improve reliability of the natural gas transmission systems that serve northern Nevada. Final permitting for the project is pending before the U.S. Bureau of Land Management and other state and local agencies.

In May 2001, TGTC completed construction of approximately 3,520-feet of pipeline with meter and flow control to serve a 360 MW plant, a new interruptible transportation customer east of Reno, Nevada near SPPC's Tracy Power Plant, and in September, 2001, TGTC completed construction of a 10.8-mile pipeline to serve two new customers: the City of Susanville and the Department of Correction both in California.

GENERAL - EMPLOYEES (ALL)

SPR and its subsidiaries had 3,333 employees as of December 31, 2001, of which 1,787 were employed by NPC and 1,415 were employed by SPPC.

NPC's current contract with the International Brotherhood of Electrical Workers (IBEW) Local No. 396, which covers 55% of NPC's workforce, was renegotiated in February 2002 and is in effect until February 1, 2005. The contract provides for a 3% general wage increase for bargaining unit employees effective February 2, 2002, with 3% increases in 2003 and 2004.

SPPC's current contract with the IBEW Local No. 1245, which represents 62% of SPPC's workforce, was renegotiated in March 2000 and is in effect until December 31, 2002. The two-year contract provided for 3% general wage increases for bargaining unit employees beginning January 1, 2001, and January 1, 2002. In addition, the contract provides for participation by bargaining unit employees in the incentive compensation program.

GENERAL - FRANCHISES (NPC AND SPPC)

The Utilities have nonexclusive local franchises or revocable permits to carry on their business in the localities in which their respective operations are conducted in Nevada and California. The franchise and other governmental requirements of some of the cities and counties in which the Utilities operate provide for payments based on gross revenues. During 2001, the state also passed a law requiring public utilities to collect from their customers a fee based on consumption. This universal energy charge is to help those customers who need assistance in paying their utility bills or need help in paying for ways to reduce energy consumption. During 2001, the Utilities collected $58.3 million in franchise or other fees based on gross revenues. They collected $3.9 million in universal energy charges based on consumption. They also paid and recorded as expense $0.5 million of fees based on net profits.

Item 3. Legal Proceedings

Sierra Touch America LLC (STA), a partnership between SPC and Touch America, a subsidiary of Montana Power Company, is constructing a fiber optic line between Salt Lake City, Utah and Sacramento, CA. The conduits included in the line are under contract to be sold to AT&T, PF Net corporations, and STA. SPC is responsible for 50% of the partnership's operating expenses and shares in the construction cost of the fiber network. Construction activity between Sacramento and Reno commenced in July 2000, and the estimated completion date has been moved to early 2003. Williams Communications, LLC ("Williams") has filed a complaint in United States District Court alleging that STA has failed to make timely payment on invoices in connection with a construction agreement between Williams and STA. TI Energy Services ("TI") has filed a complaint in the District Court of Harris County, Texas, alleging that STA has failed to make timely payment on invoices in connection with a services agreement between TI and STA, whereby TI is to provide services for certain segments of the fiber optic line. Although SPC's ultimate liability, if any, cannot be estimated, Management believes the final outcome of the litigation is not likely to have a material adverse effect on SPR's financial position or results of operations.

SPPC owns a 345 kV transmission line that connects SPPC to the facilities of the Bonneville Power Administration ("BPA") near Alturas, California. The Transmission Agency of Northern California ("TANC") initiated proceedings in the United States District Court for the Eastern District of California and the United States Court of Appeals for the Ninth Circuit, in each case alleging that BPA's construction of a small portion of the Alturas Intertie violated the Northwest Power Preference Act and requesting an injunction prohibiting operation of the Alturas Intertie. The case before the Eastern District was dismissed for lack of jurisdiction. The case before the Ninth Circuit was dismissed for TANC's failure to prosecute. In December 1999, TANC filed suit in the Superior Court of the State of California, Sacramento County, seeking an injunction against operation of the Alturas Intertie based on numerous allegations under state law, including inverse condemnation, trespass, private nuisance, and conversion. That case was removed to Federal Court and dismissed by the trial court, and is now on appeal in the Ninth Circuit. Although SPPC's ultimate liability, if any, cannot be estimated at this time, Management believes the final outcome of the appeal and any subsequent litigation is not likely to have a material adverse effect on SPR's financial position or results of operation.

See Environment in Item 1, Business, for information on environmental proceedings.

SPR and its subsidiaries, through the course of their normal business operations, are currently involved in a number of other legal actions, none of which has had or, in the opinion of management, is expected to have a significant impact on their financial positions or results of operations.

Common Stock:     $1.00 Par Value                As of March 15, 2002: 25,019

Dividends are considered periodically by SPR's Board of Directors and are subject to factors that ordinarily affect dividend policy, such as current and prospective earnings, current and prospective business conditions, regulatory factors, SPR's financial condition and other matters within the discretion of the Board. As a result of the unprecedented conditions in the wholesale energy markets that negatively affected SPR's earnings prior to the restoration of deferred energy accounting in Nevada, the Board of Directors decided on April 13, 2001 not to pay the Common Stock dividend that, if it had followed historical practices, would have been paid in May 2001. Following the passage of legislation in Nevada which reinstated deferred energy accounting for electric utilities, the Board re-examined the factors described previously and on July 20, 2001 declared a dividend of $.20 per share on SPR's Common Stock, payable September 15, 2001. The Board of Directors also established the following schedule for when future dividends would normally be paid, if declared: December 15, March 15, June 15 and September 15. The Board subsequently voted on November 6, 2001 to declare a dividend of $.20 per share, payable December 15, 2001. The Board will continue to review these factors on a periodic basis to determine if and when it would be prudent to declare a dividend on SPR's Common Stock. There is no guarantee that dividends will be paid in the future, or that, if paid, the dividends will be paid at the same amount or with the same frequency as in the past.

34

On February 6, 2002, the SPR Board of Directors declared a quarterly common dividend of $.20 per share. This dividend of approximately $20.4 million will be paid on March 15, 2002, to holders of record as of February 22, 2002.

The primary source of funds for the payment of dividends to SPR's stockholders is dividends paid to SPR by NPC and SPPC on their common stock, all of which is owned by SPR. These two subsidiaries are public utilities and are subject to regulation by state utility commissions which may impose limits on investment returns or otherwise impact the amount of dividends which may be paid by those companies. Moreover, the Articles of Incorporation of SPPC contain restrictions on the payment of dividends on SPPC's common stock in the event of a default in the payment of dividends on SPPC's preferred stock. Similarly, the bank credit facilities of NPC and SPPC prohibit the payment of dividends on each company's common stock if that company is in default under the terms of the relevant credit facility. Finally, the terms of certain outstanding series of first mortgage bonds of both NPC and SPPC contain certain quantitative limits on the amount of dividends that may be paid on each company's common stock.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information in this Form 10-K includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements relate to anticipated financial performance, management's plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters. Words such as "anticipate," "believe," "estimate," "expect," "intend," "plan" and "objective" and other similar expressions identify those statements that are forward-looking. These statements are based on management's beliefs and assumptions and on information currently available to management. Actual results could differ materially from those contemplated by the forward-looking statements. In addition to any assumptions and other factors referred to specifically in connection with such statements, factors that could cause the actual results of Sierra Pacific Resources (SPR), Nevada Power Company (NPC), or Sierra Pacific Power Company (SPPC) to differ materially from those contemplated in any forward-looking statement include, among others, the following:

(1) unfavorable rulings in rate cases previously filed and to be filed by NPC and SPPC (the "Utilities") with the Public Utilities Commission of Nevada (PUCN), including the periodic applications authorized by recent Nevada legislation to permit the Utilities to recover costs for fuel and purchased power that have been recorded by the Utilities in their deferred energy accounts and deferred natural gas recorded by SPPC for its gas distribution business;

(2) the ability of SPR, NPC and SPPC to access the capital markets to support their requirements for working capital, including amounts necessary to finance deferred energy costs, construction costs and the repayment of maturing debt, particularly in the event of unfavorable rulings by the PUCN and/or a downgrade of the existing debt ratings of SPR, NPC or SPPC;

(3) whether the PUCN will issue favorable orders in a timely manner to permit the Utilities to borrow money and issue additional securities to finance the Utilities' operations and to purchase power and fuel necessary to serve their respective customers;

(4) the extent to which volatile energy prices and the financial difficulties of electric utilities and power exchanges in the western United States cause any counterparties to the Utilities' purchased power contracts to default on their obligations, thus requiring the Utilities to seek to replace the power on the spot market;

(5) the effect of price controls promulgated in June 2001 by the Federal Energy Regulatory Commission ("FERC") on the price at which the Utilities can sell excess power in the wholesale markets;

(6) the effect that any future terrorist attacks may have on the tourism and gaming industries in Nevada, particularly in Las Vegas, as well as on the economy in general;

(7) the effect of existing or future Nevada, California or federal legislation or regulations affecting electric industry restructuring, including laws or regulations which could allow certain customers to choose new electricity suppliers;

(8) unseasonable weather and other natural phenomena, which can have potentially serious impacts on the Utilities' ability to procure adequate supplies of fuel or purchased power to serve their respective customers and on the cost of procuring such supplies;

38

(9) industrial, commercial and residential growth in the service territories of the Utilities;

(10) the loss of any significant customers;

(11) changes in the business of major customers, including those engaged in gold mining or gaming, which may result in changes in the demand for services of the Utilities;

(12) changes in environmental regulations, tax or accounting matters or other laws and regulations to which the Utilities are subject;

(13) future economic conditions, including inflation rates and monetary policy;

(14) financial market conditions, including changes in availability of capital or interest rate fluctuations;

(15) unusual or unanticipated changes in normal business operations, including unusual maintenance or repairs; and

(16) employee workforce factors, including changes in collective bargaining unit agreements, strikes or work stoppages.

Other factors and assumptions not identified above may also have been involved in deriving these forward-looking statements, and the failure of those other assumptions to be realized, as well as other factors, may also cause actual results to differ materially from those projected. SPR, NPC and SPPC assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking statements.

CRITICAL ACCOUNTING POLICIES

The following items represent critical accounting policies that under different conditions or using different assumptions could have a material effect on the financial condition, liquidity and capital resources of SPR and the Utilities.

Regulatory Accounting

The Utilities' rates are currently subject to the approval of the PUCN and are designed to recover the cost of providing generation, transmission and distribution services. As a result, the Utilities qualify for the application of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation", issued by the Financial Accounting Standards Board (FASB). This statement recognizes that the rate actions of a regulator can provide reasonable assurance of the existence of an asset and requires the capitalization of incurred costs that would otherwise be charged to expense where it is probable that future revenue will be provided to recover these costs. SFAS No. 71 prescribes the method to be used to record the financial transactions of a regulated entity. The criteria for applying SFAS No. 71 include the following: (i) rates are set by an independent third party regulator, (ii) approved rates are intended to recover the specific costs of the regulated products or services, and (iii) rates that are set at levels that will recover costs can be charged to and collected from customers.

39

Deferred Energy Accounting

On April 18, 2001, the Governor of Nevada signed into law Assembly Bill (AB) 369. The provisions of AB 369, which are described in greater detail in "Regulation and Rate Proceedings," later, include, among others, a reinstatement of deferred energy accounting for fuel and purchased power costs incurred by electric utilities. In accordance with the provisions of SFAS No. 71, the Utilities began utilizing deferred energy accounting on March 1, 2001, for their respective electric operations. Under deferred energy accounting, to the extent actual fuel and purchased power costs exceed fuel and purchased power costs recoverable through current rates, that excess is not recorded as a current expense on the income statement but rather is deferred and recorded as an asset on the balance sheet. Conversely, a liability is recorded to the extent fuel and purchased power costs recoverable through current rates exceed actual fuel and purchased power costs. These excess amounts are reflected in adjustments to rates and recorded as revenue or expense in future time periods, subject to PUCN review. AB 369 provides that the PUCN may not allow the recovery of any costs for purchased fuel or purchased power "that were the result of any practice or transaction that was undertaken, managed or performed imprudently by the electric utility." In reference to deferred energy accounting, AB 369 specifies that fuel and purchased power costs include all costs incurred to purchase fuel, to purchase capacity, and to purchase energy. The Utilities also record, and are eligible to recover, a carrying charge on such deferred balances.

If not for deferred energy accounting during 2001, SPR's, NPC's and SPPC's results of operations, financial condition, liquidity and capital resources would have been materially adversely affected. For example, without the deferred energy accounting provisions of AB 369, the 2001 reported net income of SPR, NPC and SPPC of $56.7 million, $63.4 million/1/ and $45.9 million would have been (net of income tax) reported as net losses of ($715.4) million, ($573.6) million/1/ and ($89.1) million, respectively. In addition, a significant disallowance by the PUCN of costs currently deferred would have a material adverse affect on the future results of operations of SPR, NPC and SPPC. See "Regulation and Rate Proceedings," later, for a more detailed discussion of deferred energy accounting, including the regulatory process underway to recover these deferred costs.

Derivatives and Hedging Activities

Effective January 1, 2001, SPR, SPPC, and NPC adopted SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS No. 138. As amended, SFAS No. 133 requires that an entity recognize all derivative instruments as either assets or liabilities in the statement of financial position and measure the instruments at fair value.

In order to manage loads, resources and energy price risk, the Utilities buy fuel and power under forward contracts. In addition to forward fuel and power purchase contracts, the Utilities also use options and swaps to manage price risk. All of these instruments are considered to be derivatives under SFAS No. 133. The risk management assets and liabilities recorded in the balance sheets of the Utilities and SPR are primarily comprised of the fair value of these forward fuel and power purchase contracts and other energy related derivative instruments.

With the reinstatement of deferred energy accounting pursuant to AB 369, prudently incurred fuel and purchased power costs are expected to be recoverable through future rates. Accordingly, the energy related risk management assets and liabilities and the corresponding unrealized gains and losses (changes in fair value) are offset with a regulatory asset or liability rather than recognized in the statements of income and comprehensive income. Upon settlement of the derivative instrument, actual fuel and purchased power costs are recognized or deferred to the extent they are recoverable or payable through future rates.

The fair values of the forward contracts and swaps are determined based on quotes obtained from independent brokers and exchanges. The fair values of options are determined using a pricing model which incorporates assumptions such as the underlying commodity's forward price curve, time to expiration, strike price, interest rates, and volatility. The use of different assumptions and variables in the model could have a significant impact on the valuation of the instruments.

SPR and the Utilities have other non-energy related derivative instruments such as interest rate swaps. The transition adjustment resulting from the adoption of SFAS No. 133 related to these types of derivative instruments was reported as the cumulative effect of a change in accounting principle in Other Comprehensive Income. Additionally, the changes in fair values of these non-energy related derivatives are also reported in the statements of comprehensive income until the related transactions are settled or terminate, at which time the amounts will be reclassified into earnings. No amounts were reclassified into earnings during 2001.

See Note 22 of "Notes to Financial Statements" for additional information regarding derivatives and hedging activities.

Provision for Uncollectible Accounts

The Utilities reserve for doubtful accounts based on past experience writing off uncollectible customer accounts. The collapse of the energy markets in California, and the subsequent bankruptcy of the California Power Exchange and the financial difficulties of the Independent System Operator, resulted in the Utilities reserving for outstanding receivables for power purchases by these two entities of $19.9 million and $1.5 million (before taxes) for NPC and SPPC, respectively. The weakening economy and the disruption to the leisure travel industry after September 11th also impacted the Utilities' customer delinquencies in 2001. Additional amounts of $14.8 million and $6.1 million were reserved for delinquent retail customer accounts of NPC and SPPC, respectively. The adequacy of these reserves will vary to the extent that future collections differ from past experience. Uncollectible retail customer accounts amounting to $5.6 million and $2.5 million respectively, for NPC and SPPC, were written off against this provision in 2001. Significant collection efforts are underway to recover portions of the rest of the delinquent accounts.

MAJOR FACTORS AFFECTING RESULTS OF OPERATIONS

As discussed in the results of operations sections that follow, operating results for 2001 were affected by the high and extremely volatile fuel and purchased power costs that developed in the western United States in 2000 and continued into 2001, and by several responsive legislative and regulatory actions.

In an effort to mitigate the effects of higher fuel and purchased power costs, in July 2000, the Utilities entered into the Global Settlement with the PUCN, which established a mechanism that initiated incremental rate increases for each Utility. Cumulative electric rate increases under the Global Settlement were $127 million and $65 million per year, respectively, for the Utilities.

However, because the rate adjustment mechanism of the Global Settlement was subject to certain caps and could not keep pace with the continued escalation of fuel and purchased power prices, on January 29, 2001, the Utilities filed a Comprehensive Energy Plan (CEP) with the PUCN. The CEP included a request for emergency rate increases (CEP Riders). On March 1, 2001, the PUCN permitted the requested CEP Riders to go into effect subject to later review. The CEP Riders provided further rate increases of $210 million and $104 million per year, respectively, for NPC and SPPC.

41

Notwithstanding the increases under the Global Settlement and the CEP Riders, the Utilities' revenues for fuel and purchased power recovery continued to be less than the related expenses. Accordingly, the Utilities sought additional relief pursuant to legislation.

On April 18, 2001, the Governor of Nevada signed into law AB 369. The provisions of AB 369, which are described later in greater detail in "Regulation and Rate Proceedings," include a moratorium on the sale of generation assets by electric utilities until 2003, the repeal of electric industry restructuring, and, beginning March 1, 2001, a reinstatement of deferred energy accounting for fuel and purchased power costs incurred by electric utilities. The stated purposes of this emergency legislation included, among others, to control volatility in the price of electricity in the retail market in Nevada and to ensure that the Utilities have the necessary financial resources to provide adequate and reliable electric service under present market conditions.

As discussed above in "Critical Accounting Policies," deferred energy accounting allows the Utilities an opportunity to recover in future periods that portion of their costs for fuel and purchased power not covered by current rates and defers to future periods the expense associated with the amounts by which fuel and purchased power costs exceed the costs to be recovered in current rates. Recovery is subject to PUCN review as to prudency and other matters.

AB 369 requires each Utility to file general rate applications and deferred energy applications with the PUCN by specific dates. NPC's deferred energy application, filed on November 30, 2001, seeks to establish a Deferred Energy Accounting Adjustment ("DEAA") rate to clear accumulated purchased fuel and power costs of $922 million and spread the cost recovery over a not more than three-year period resulting in a net increase of 21%. The decision of the PUCN on NPC's deferred energy application is to take effect on April 1, 2002. SPPC's deferred energy application, filed on February 1, 2002, seeks to establish a DEAA rate to clear accumulated purchased fuel and power costs of $205 million and spread the cost recovery over a not more than three-year period resulting in a net increase of 9.8%. The PUCN decision on SPPC's deferred energy application is to take effect on June 1, 2002. See "Regulation and Rate Proceedings," later, for a discussion of the Utilities' general rate case filings.

The decisions of the PUCN on the Utilities' deferred energy applications are expected to have a significant effect on the results of operations of SPR, NPC, and SPPC in 2002 and subsequent periods, and may have a material effect on the financial condition, liquidity, and capital resources of SPR, NPC, and SPPC. In particular, to the extent that the PUCN finds that any amount included in either Utility's deferred account was imprudently incurred, the PUCN will not permit that amount to be recovered through higher rates, and an equivalent amount of the Utility's deferred energy costs asset will be required to be written off. Such a write-off could cause a substantial loss to be incurred by the Utility, could cause its securities to be downgraded by the rating agencies and could make it significantly more difficult to finance the operations of the Utility and to buy fuel and purchased power from third parties. In the event that a significant amount of the Utilities' deferred energy costs are disallowed by the PUCN, there can be no assurance that SPR, NPC, or SPPC will be able to remain solvent.

As discussed in greater detail in "Regulation and Rate Proceedings," on June 19, 2001, the FERC adopted a price mitigation plan applicable to spot market wholesale power sales in California and throughout the western United States during the period June 20, 2001 through September 30, 2002. The price mitigation plan established a mechanism with which to determine the maximum amount that may be charged for power sold during this period. Although the Utilities are not able to predict at this time the long-term effect that the FERC price mitigation plan and other market developments may have on their results of operations, management believes that, under certain market conditions, the FERC plan adversely affects the availability of spot market power to the Utilities and reduces the price at which the Utilities can sell power on the wholesale market. Another potential result from these price mitigation measures could be the delay and/or cancellation of proposed power plants throughout the western United States. If these results occur, the long-term supply of energy could be reduced. Numerous parties, including NPC and several northwest utilities, appealed the FERC order to the District of Columbia Court of Appeals on the basis that the price caps are unfair to electric customers who reside outside of California. The parties to the appeal await action by the Court.

Results of Operations

SPR earned $56.7 million for the year ended December 31, 2001, compared to a net loss of ($39.8) million in 2000, and net income of $51.8 million in 1999. NPC and SPPC, SPR's principal subsidiaries, declared common stock dividends to their parent, SPR, of $33 million and $63 million, respectively. SPPC also declared $3.9 million in dividends to holders of its preferred stock.

Liquidity and Capital Resources (SPR Consolidated)

SPR's net cash flows during 2001 were comparable to 2000. An increase in net cash flows used for operating activities was offset by a decrease in cash used for investing activities and an increase in cash provided from financing activities. The increase in cash used in operating activities resulted substantially from the payment of higher energy and natural gas costs. The decrease in cash used for investing activities resulted from the sale of SPPC's water business. The increase in cash provided from financing activities resulted from a reduction in net retirements of short-term debt and proceeds from the sale of common stock. Cash provided by financing activities was substantially utilized for the payment of higher energy costs in 2001. See Notes 7 (Common Stock and Other Paid-in Capital) and 12 (Short-Term Borrowings) for detailed financing information.

SPR's net cash flows increased in 2000 compared to 1999. The net increase in cash resulted from less cash used in investing activities offset substantially by decreases in cash from operating and financing activities. The decrease in cash flows used in investing activities is due to the merger cash requirements included in the 1999 amounts. Cash flows from operating activities were less in 2000 due primarily to a decrease in operating income and an increase in accounts receivable, offset, in part, by increases in accounts payable and depreciation and amortization. Cash flows from financing activities decreased in 2000 compared to 1999 because most of the cash provided by long-term debt issued in 2000 was utilized to retire short-term borrowings and other long-term debt. See Notes 9 (Long Term-Debt) and 12 (Short-Term Borrowings) for detailed financing information.

Since SPR is a holding company, substantially all of its cash flow is provided by dividends paid to SPR by NPC and SPPC on their common stock, all of which is owned by SPR. Since these two subsidiaries are public utilities, they are subject to regulation by state utility commissions which may impose limits on investment returns or otherwise impact the amount of dividends which may be paid by those companies. Moreover, the Articles of Incorporation of SPPC contain restrictions on the payment of dividends on SPPC's common stock in the event of a default in the payment of dividends on SPPC's preferred stock. Similarly, the Credit Agreements of NPC and SPPC prohibit the payment of dividends on each company's common stock if that company is in default under the terms of the relevant credit facility. Finally, the terms of certain outstanding series of first mortgage bonds of both NPC and SPPC limit the cumulative amount of dividends that may be paid on each company's common stock to the cumulative net earnings of that company over an extended period of time. Any of these provisions which potentially restrict dividends payable by NPC or SPPC could adversely affect liquidity at the SPR level.

In addition to the liquidity provided by dividends from its subsidiaries, SPR maintains $75 million of short-term liquidity capacity at the holding company level in the form of a Credit Agreement with the same bank group that has entered into Credit Agreements with NPC and SPPC. This facility matures on November 28, 2002 and may be used to provide liquidity for general corporate purposes including to back up a commercial paper program, although SPR does not currently maintain a commercial paper program. The Credit Agreement contains a number of restrictive covenants including restrictions on liens, sales of assets and mergers or sale and leaseback transactions by SPR or its subsidiaries. The Credit Agreement also contains financial covenants requiring that SPR maintain:

43

. a ratio of (i) Total Indebtedness to (ii) the sum of Total Indebtedness and Shareholders Equity that does not exceed 0.65:1 as of the last day of each fiscal quarter.
. a Consolidated Interest Coverage Ratio of not less than 1.5 to 1 calculated as of the last day of each fiscal quarter for the preceding four consecutive fiscal quarters.

As of December 31, 2001, SPR was in compliance with these financial covenants.

The borrowing costs under the Credit Agreement are at a variable interest rate consisting of a spread over LIBOR or an alternate base rate that is based upon a pricing grid tied to the credit rating on SPR's senior unsecured long-term debt. SPR had no borrowings outstanding under the Credit Agreement as of December 31, 2001. On or before the maturity date of the Credit Agreement, SPPC currently intends to either renew or replace the Credit Agreement.

Like the Credit Agreements for NPC and SPPC, SPR's Credit Agreement is unsecured. However, SPR's Credit Agreement does not require the issuance of collateral to the banks in the event that the credit rating on SPR's long-term unsecured debt is downgraded.

* 1999 cash construction expenditures include $448.3 million of merger related costs.

SPR's estimated cash construction expenditures for 2002 through 2006 are $1.7 billion. Construction expenditures for 2002 (approximately $470 million) will be financed through debt issuance and internally generated funds, including recovery of deferred energy. It is anticipated that the Utilities will pay all of their net income in dividends to SPR. SPR anticipates capital contributions of $16 million to NPC and $60 million to SPPC in 2002. SPPC will utilize proceeds from the issuance of short-term debt and parent contributions to fund construction.

Cash provided by internally generated funds during 2002 assumes full recovery of deferred energy costs over three years for NPC and SPPC. SPR also assumes general rate increases approved as filed effective at the beginning of the second quarter and mid-year for NPC and SPPC, respectively. To the extent that the PUCN finds that any of the Utilities' deferred energy costs resulted from imprudent purchases, the PUCN will not permit that amount to be recovered through higher rates, and an equivalent amount of the Utilities' deferred energy cost asset will be required to be written off. A material write-off of deferred energy costs would have a material adverse affect on the future results of operations of SPR and the Utilities and could cause their securities to be downgraded by the rating agencies and make it significantly more difficult to finance operations, and buy fuel and purchased power from third parties.

44

If SPR does not receive substantial recovery of deferred energy costs for the Utilities, depending upon the extent of the disallowance, the rating agencies might downgrade SPR and its subsidiaries. A downgrade by one or more of the national rating agencies of the credit rating for the debt of SPR, NPC or SPPC would affect the companies' liquidity primarily in two principal areas: (1) their respective financing arrangements and (2) NPC's and SPPC's contracts for fuel, for purchase and sale of electricity and for transportation of natural gas.

With respect to the financing arrangements, in the event that either NPC's or SPPC's commercial paper programs are downgraded, the downgraded issuer would no longer be able to issue commercial paper, thereby requiring the issuer to draw upon its back-up credit facility to pay off outstanding commercial paper balances. With respect to other financing arrangements, a downgrade in and of itself would not trigger an event of default or otherwise accelerate the payment obligations under any of SPR's, NPC's or SPPC's financing agreements. However, the bank Credit Agreements of NPC and SPPC include a "springing lien" feature, pursuant to which NPC or SPPC would be required, in the event that the company's senior unsecured debt is downgraded, to issue General and Refunding Mortgage bonds to the banks in an amount equal to the aggregate principal amount of the commitments under the facilities. If the springing lien were triggered for NPC, NPC would likely be obligated, under a negative pledge clause applicable to its senior unsecured notes, to issue an additional $130 million of General and Refunding Bonds as collateral for those securities.

With respect to NPC's and SPPC's contracts for purchased power, NPC and SPPC purchase and sell electricity with their counterparties under the Western Systems Power Pool ("WSPP") agreement, which is an industry standard contract. The WSPP contract is posted on the WSPP website. These contracts provide that a material adverse change may trigger a request for collateral, which, if not provided within 3 business days, may trigger a default. A request for collateral must be exercised within 30 days of the event becoming known. A default will result in a termination payment equal to the present value of the net gains and losses aggregated to a single liquidated amount due within 3 business days following the date the notice of termination is received. The mark to market value can be used to roughly approximate the termination payment at any point in time.

With respect to the purchase and sale of natural gas, NPC and SPPC use several types of contracts. Standard industry sponsored agreements include: (1) the Gas Industry Standards Board ("GSIB") agreement which is used for physical gas transactions, (2) the GasEDI Base Contract for Short Term Sale and Purchase of Natural Gas which is also used for physical gas transactions, or (3) the International Swap Dealers Association (ISDA) agreement which is used for financial gas transactions. Alternatively, the gas transactions might be governed by a non-standard bilateral master agreement negotiated between the parties, or by the confirmation associated with the transaction. The natural gas contract terms and conditions are more varied than the electric contracts. Consequently, some of the contracts do not contain rating downgrade triggers and some contain language similar to that found in the WSPP agreement.

Gas transmission services are provided under the FERC Gas Tariff or a custom agreement. These contracts require the entities to establish and maintain creditworthiness to obtain service.

Contractual Obligations (SPR Consolidated)

The table below provides SPR's consolidated contractual obligations, not including estimated construction expenditures described above, as of December 31, 2001, that SPR expects to satisfy through a combination of internally generated cash and, as necessary, through the issuance of short-term and long-term debt (dollars in thousands):

The merger between SPR and NPC was accounted for as a reverse purchase under generally accepted accounting principles, with NPC considered the acquiring entity, even though SPR became the legal parent of NPC. For accounting purposes, the merger was deemed to have occurred on August 1, 1999. As a result of this reverse purchase accounting treatment: (i) the historical financial statements of SPR for periods prior to the date of the merger are no longer the financial statements of SPR, and therefore, are no longer presented; (ii) the historical financial statements of SPR for periods prior to the date of the merger are those of NPC; (iii) based on a merger date of August 1, 1999, the Consolidating Statements of Income for the twelve months ended December 31, 1999, include five months (August through December 1999) of operating activity for SPR and its subsidiaries other than NPC and include the operating results of NPC for the entire periods presented; and (iv) each of the Consolidating Statements of Income for the twelve months periods ended December 31, 2001 and 2000, include twelve months of operating activity for SPR and its subsidiaries.

NPC's retail revenues increased in 2001 due to a combination of customer growth, and rate increases resulting from the Global Settlement and Comprehensive Energy Plan (CEP) (see Major Factors Affecting Results Of Operations, earlier). The number of residential, commercial, and industrial customers increased over the prior year by 4.8%, 4.4% and 6.5%, respectively. As a result of the CEP, a rate increase of 17% for retail customers became effective March 1, 2001. Substantially all of the increase in Other electric revenues was due to the sale of wholesale electric power to other utilities. NPC's increase in wholesale sales compared to 2000 was a result of market conditions and NPC's power procurement activities. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

NPC's retail revenues increased in 2000 due to a combination of customer growth, warmer than normal weather, and rate increases resulting from the Global Settlement. The number of residential, commercial, and industrial customers increased over the prior year by 5.6%, 4.6% and 7.4%, respectively. As a result of the Global Settlement, NPC implemented monthly rate increases starting August 1, 2000. Other electric revenues were higher in 2000 compared to 1999 due to increased sales of wholesale electric power to other utilities. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

NPC's purchased power costs were significantly higher in 2001 due to substantial increases in prices and volumes. Per unit costs of power increased 126% primarily due to higher Short-Term Firm energy prices. These price increases were the result of much higher fuel costs, combined with increased demand and limited power supplies. Volumes purchased rose 100% to accommodate increases in system load of approximately 2.7% and increases in wholesale sales of approximately 310%. Purchases associated with risk management activities, which include transactions entered into for hedging purposes and to optimize purchased power costs, are included in the purchased power amounts. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

Purchased power costs were higher in 2000 as compared to 1999 due to a 23% increase in the volume purchased and an increase in the per unit cost of power of 61%.

NPC's 2001 fuel expense increased over 50% compared to 2000 primarily due to a substantial increase in natural gas prices, offset in part, by decreased generation late in 2001 when the cost of purchased power was more economical than generation. In 2000, NPC's fuel expense increased 89% compared to 1999 primarily due to a substantial increase in natural gas prices.

NPC recorded a significant Deferral of energy costs-net in 2001 due to the implementation of deferred energy accounting beginning March 1, 2001. The current year amounts reflect the extent to which actual fuel and purchased power costs exceeded the fuel and purchased power costs recovered through current rates. Deferral of energy costs-net for 2000 represents energy costs that had been deferred in prior periods and were then recovered in 2000, as a result of deferred energy rate increases granted in 1999.

Deferral of energy costs-net decreased in 2000 compared to 1999 because NPC discontinued deferred energy cost accounting effective August 1, 2000, pursuant to the July 2000 Global Settlement with the PUCN, and because of decisions, described below, by the PUCN affecting 1999's Deferral of energy costs-net. For more information on the Global Settlement, see Major Factors Affecting Results Of Operations, earlier.

In February and March 2000, the PUCN issued orders that rejected NPC's requested rate relief in its 1999 deferred energy filings. As a result of these decisions, a pre-tax charge of $80 million to Deferral of energy costs-net was made in 1999 to write-off deferred energy and imputed capacity costs.

See "Critical Accounting Policies," earlier, and Note 1 of "Notes to Financial Statements" for more information regarding deferred energy accounting.

NPC AFUDC is lower in 2001 because of adjustments to amounts assigned to specific components of facilities that were completed in different periods. In 2000, there was a small decrease in the AFUDC rate compared to 1999 because of an increase in short-term debt.

Other operating expense increased in 2001 compared to 2000 due to a $16.6 million larger addition to the provision for uncollectible customer accounts than in 2000, reflecting the impact of the weakening economy and disruption to the leisure travel industry after September 11, 2001. Other operating expense also increased due to the addition of $12.6 million to the uncollectible provision related to receivables from the California Power Exchange (PX) and California's Independent System Operator (ISO). NPC's other operating expense for 2000 was $8.8 million lower than 1999 due to reduced labor and benefit costs as a result of merger efficiencies and unfilled vacancies. These savings were offset, in part, by an increase in the provision for uncollectible accounts that included a provision of $7.3 million related to the PX and ISO.

The level of NPC's maintenance and repair expenses depends primarily upon the scheduling, magnitude and number of generation unit overhauls at NPC's generating stations. Maintenance expense for 2001 increased from the prior year as a result of increased outage work at Reid-Gardner, additional expenditures for repairs and outages at Clark Station and increased work at Mohave. In 2000 maintenance expense decreased from the prior year primarily as a result of fewer planned plant maintenance activities at NPC's coal generation facilities. In addition, in 2000 crews performed required activities of a capital nature, thereby reducing the amount of maintenance expense.

An increase in plant-in-service was the cause of NPC's increase in depreciation and amortization expense in 2001 compared to 2000. Depreciation and amortization was also higher in 2000 than 1999 due to an increase in plant-in-service.

As a result of net income for 2001, NPC incurred income tax expense. Due to a net loss in 2000, NPC recorded an income tax benefit for the year. See Note 10 of "Notes to Financial Statements" for additional information regarding the computation of income taxes.

NPC's interest charges on long-term debt increased in 2001 compared to 2000, following a net increase in associated debt of $450 million (new issuances of $700 million and redemptions of $250 million during 2001). Interest charges on long-term debt for 2000 were comparable to 1999s. See Note 9 of "Notes to Financial Statements" for additional information regarding long-term debt.

NPC's interest charges-other in 2001 were comparable to 2000. Interest charges-other increased in 2000 compared to 1999 due to increased debt through the issuance of commercial paper in 2000 and due to interest costs associated with the issuance of floating rate notes in October 1999 and June, August, and December 2000.

NPC's other income (expense) - net improved in 2001 due primarily to the recognition in the current year of carrying charges on deferred fuel and purchased power balances pursuant to AB 369. Other income

53

(expense)-net improved in 2000 over the prior year as a result of greater increases in life insurance cash surrender values and reductions in contributions and membership dues.

Liquidity and Capital Resources

NPC's net cash flows decreased in 2001 compared to 2000. The net decrease in cash resulted from a significant increase in cash flows used in operating activities combined with cash used in investing activities both partially offset by an increase in cash provided by external financing sources. The increase in cash flows used in operating activities resulted substantially from the payment of significantly higher energy costs during 2001. Net cash used in investing activities was comparable between 2001 and 2000. Net cash provided by financing activities was higher in 2001 as a result of cash provided by the issuance of short-term and long-term debt, as described in Notes 12 and 9 to the Financial Statements, and additional capital contributions from SPR. Cash provided by financing activities was substantially utilized for the payment of higher energy costs in 2001.

NPC's net cash flows increased in 2000 compared to 1999. The net increase in cash resulted from less cash used in investing activities and more cash provided by financing activities. A reduction in the net cash used for utility plant was the main cause for the decrease in cash used for investing activities. The increase in cash flows from financing activities was due to an increase in funding received from SPR (less dividends paid) offset, in part, by less cash provided by the net issuance of long and short-term debt. The overall net increase in cash was also partially offset by a reduction in cash received from operating activities that was mainly due to a decrease in operating income.

As discussed in "Construction Expenditures and Financing" and "Capital Structure" that follow, NPC anticipates external capital requirements for construction costs and for the repayment of maturing short-term and long-term debt during 2002 totaling approximately $403 million, which NPC will fund through a combination of (i) internally generated funds, (ii) the issuance of short-term debt and preferred stock, and (iii) capital contributions from SPR.

NPC's primary source of short-term liquidity has been its commercial paper program, pursuant to which it sells commercial paper of varying maturities through dealers to institutional purchasers of commercial paper. NPC's current program permits the sale of up to $200 million of commercial paper on a revolving basis. As of December 31, 2001, NPC had $130.5 million of commercial paper outstanding, representing all of NPC's short-term debt as of that date. As is customary for an A2/P2 commercial paper issuer, NPC's commercial paper program requires that NPC maintain a back-up credit facility in the event that NPC is unable to sell additional commercial paper to pay off outstanding commercial paper due to conditions within the commercial paper market or due to a downgrade in the credit rating of NPC's commercial paper. Accordingly, if there ever were an event of default under or cancellation or termination of the back-up credit facility, NPC would not be able to issue commercial paper until NPC obtained another back-up credit facility or until the default were waived or cured.

As discussed in "Capital Structure" below, NPC has a Credit Agreement with a number of banks which matures on November 28, 2002. Although this facility may be used to provide liquidity for general corporate purposes, it has been used primarily by NPC to back up its commercial paper program. The Credit Agreement contains a number of restrictive covenants including restrictions on liens, sales of assets, mergers, and sale and leaseback transactions. The Credit Agreement also contains financial covenants requiring that NPC maintain:

. a ratio of (i) Total Indebtedness to (ii) the sum of Total Indebtedness and Shareholders Equity that does not exceed 0.60:1 as of the last day of each fiscal quarter.
. a Consolidated Interest Coverage Ratio of not less than 2.0:1 calculated as of the last day of each fiscal quarter for the preceding four consecutive fiscal quarters.

54

As of December 31, 2001, NPC was in compliance with these financial covenants.

The borrowing costs under the Credit Agreement are at a variable interest rate consisting of a spread over LIBOR or an alternate base rate that is based upon a pricing grid tied to the credit rating on NPC's senior unsecured long-term debt. NPC had no borrowings outstanding under the Credit Agreement as of December 31, 2001. On or before the maturity date of the Credit Agreement, NPC currently intends to either renew or replace the Credit Agreement.

The Credit Agreement is currently unsecured. However, NPC will be required to secure the Credit Agreement through the issuance of General and Refunding Mortgage bonds to the lenders in the event that the credit rating on NPC's senior unsecured long-term debt is downgraded (i) by Moody's Investors Service, Inc. to Baa3 or lower or (ii) by Standard & Poor's Ratings Group to BB+ or lower. The Credit Agreement requires NPC to maintain sufficient capacity under its General and Refunding Mortgage Indenture to satisfy this collateral requirement.

NPC and SPPC are currently negotiating receivables purchase facilities, in an aggregate principal amount not to exceed $200 million, that are expected to be finalized by the end of first quarter 2002. Under the proposed facilities, NPC and SPPC would each sell receivables in a true sale to special purpose entities that would in-turn sell those assets to a commercial paper conduit that would pay for the purchase of the assets by issuing commercial paper. These facilities will be used to provide additional liquidity for working capital and general corporate purposes in addition to NPC's existing commercial paper program. NPC expects the facility to be accounted for in compliance with SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." The special purpose entities will be wholly owned subsidiaries and their financial positions and results of operations will be reflected in the consolidated financial statements of SPR, NPC, and SPPC.

NPC's first mortgage indenture creates a first priority lien on substantially all of NPC's properties. As of December 31, 2001, $387.5 million of NPC's first mortgage bonds were outstanding. Although the first mortgage indenture allows NPC to issue additional mortgage bonds on the basis of (i) 60 percent of net utility property additions and/or (ii) the principal amount of retired mortgage bonds, NPC agreed in its General and Refunding Mortgage Indenture that it would limit the issuance of additional first mortgage bonds to not more than $80 million.

NPC's General and Refunding Mortgage Indenture creates a lien on substantially all of NPC's properties in Nevada that is junior to the lien of the first mortgage indenture. As of December 31, 2001, $490 million of NPC's General and Refunding Mortgage securities were outstanding. Additional securities may be issued under the General and Refunding Mortgage Indenture on the basis of (i) 70 percent of net utility property additions, (ii) the principal amount of retired General and Refunding Mortgage bonds and/or (iii) the principal amount of first mortgage bonds retired after delivery to the indenture trustee of the initial expert's certificate under the General and Refunding Mortgage Indenture. At December 31, 2001, NPC had the capacity to issue approximately $1.2 billion of additional General and Refunding Mortgage bonds. However, the financial covenants contained in the Credit Agreement described above may limit NPC's ability to issue additional general and refunding bonds or other debt.

NPC also has the ability to release property from the liens of the two mortgage indentures on the basis of net property additions, cash and/or retired bonds. To the extent NPC releases property from the lien of its General and Refunding Mortgage Indenture, it will reduce the amount of bonds issuable under that indenture. Under the terms of NPC's $130 million of 6.20% Senior Unsecured Notes due 2004, NPC may be required, upon the issuance of additional General and Refunding Mortgage bonds, to secure the Senior Unsecured Notes through the issuance of an equal principal amount of General and Refunding Mortgage bonds.

NPC's estimated cash construction expenditures for 2002 through 2006 are $1.118 billion. Construction expenditures for 2002 (approximately $311 million) will be financed through debt issuance and internally generated funds, including recovery of deferred energy. In 2002, NPC expects to pay all of its net income in dividends to SPR and to receive $16 million of capital contribution from SPR.

Cash provided by internally generated funds during 2002 assumes full recovery of deferred energy over three years and general rate increases approved as filed effective at the beginning of the second quarter. To the extent that the PUCN finds that any of NPC's deferred energy costs resulted from imprudent purchases, the PUCN will not permit that amount to be recovered through higher rates, and an equivalent amount of NPC's deferred energy cost asset will be required to be written off. A material write-off of deferred energy costs would have a material adverse affect on the future results of operations of NPC and could cause NPC's securities to be downgraded by the rating agencies and make it significantly more difficult to finance operations, and buy fuel and purchased power from third parties.

Contractual Obligations

Capital Structure

As of December 31, 2001, NPC had short-term debt outstanding of $130.5 miion comprised entirely of commercial paper.

On November 29, 2001, NPC put into place a $200 million unsecured revolving credit facility replacing an existing $250 million credit facility, which may be used for working capital and general corporate purposes, including commercial paper backup. This new credit facility requires NPC to issue general and refunding mortgage bonds to secure this credit facility in the event of a decline in NPC's senior unsecured debt rating. This facility will expire on November 28, 2002.

NPC's actual consolidated capital structure at December 31, 2001, and 2000 was as follows (dollars in thousands):

SIERRA PACIFIC POWER COMPANY

Results of Operations

SPPC's operating results that follow are based upon the Sierra Pacific Power Company Consolidated Statements of Income included in Item 8 of this report. SPPC's 2001 net income from continuing operations before dividend requirements on preferred stock was $22.7 million, compared to a net loss in 2000 of ($4.1) million and net income of $64.6 million in 1999.

As described in Note 17, Discontinued Operations, SPPC closed the sale of its water utility business on June 11, 2001. Accordingly, the water business is reported as a discontinued operation and the continuing operating results have been reclassified to report separately the net results of operations from the water business.

The increase in SPPC's 2001 retail revenues was primarily due to rate increases resulting from the Global Settlement and CEP - see Major Factors Affecting Results Of Operations, earlier. These rate increases partially offset the increases in fuel and purchased power costs that SPPC had incurred. Also contributing to the higher revenues was an increase in the number of residential, commercial and industrial customers of 2.8%, 3.3% and 9.3%, respectively. Substantially all of the increase in Other electric revenues was due to the sale of wholesale electric power to other utilities. SPPC's increase in wholesale sales compared to 2000 was a result of market conditions and SPPC's power procurement activities. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

58

In 2000, as a result of the Global Settlement, retail revenues were $2.9 million higher than 1999 because the PUCN allowed SPPC to begin recovering its increases in fuel and purchased power costs. The increases in residential and commercial electric revenues in 2000 were also due to warmer weather during the cooling-season than in 1999 and, to a lesser extent, by increases in the number of customers. Industrial revenues increased because of significant increases in usage per customer, primarily by mining customers. Other electric revenues were higher due to an increase in wholesale electric sales. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

Gas revenues rose in 2001, primarily due to the fact that the PUCN allowed SPPC to implement two gas rate increases (see Regulation and Rate Proceedings). These increases were the result of higher gas costs that SPPC incurred. Revenues were also higher due to increases of 5.0%, 3.1% and 10.6%, respectively, in residential, commercial and industrial customers, and an increase in wholesale revenues.

Residential, commercial and industrial gas revenues in 2000 were comparable to 1999. Increases from customer growth were largely offset by lower usage as a result of milder temperatures during the heating seasons. Overall, wholesale gas sales declined slightly in 2000 compared to 1999. A decline in wholesale volume was the result of less gas available for wholesale sales because of significant increases in the usage of gas supplies for electricity generation. This decline was nearly offset by an increase in wholesale unit prices.

Purchased power costs increased dramatically in 2001 due to Short-Term Firm purchase power prices doubling. Purchased power costs also reflect a 14% increase in wholesale sales. Purchases associated with risk management activities, which include transactions entered into for hedging purposes and to optimize purchased power costs, are included in the purchased power amounts. See Purchased Power Procurement, later, for a discussion of the Utilities' purchased power procurement strategies.

59

Purchased power costs were higher in 2000 than 1999 primarily because prices per MWh were double that of the prior year and purchased power was relied on to accommodate increased system load. Purchased power costs were also higher during 2000 due to hedging activities in response to higher purchased power prices.

Fuel for power generation costs increased 22.7% in 2001 due mainly to increased natural gas prices, and, to a lesser extent, because volumes purchased were higher to accommodate greater system load.

Fuel for generation costs in 2000 were higher than 1999 due to higher gas prices and an increase in volumes purchased.

The cost of gas purchased for resale increased in 2001 because a decrease in the quantities of gas purchased was more than offset by large increases in unit prices. The decrease in quantities purchased was the result of increased plant consumption of gas, thereby decreasing the availability of gas for wholesale activities. The significant gas price increases are consistent with the regional growth in demand for limited supplies of natural gas.

The cost of gas purchased for resale increased in 2000 because the decrease in quantities of gas purchased was again more than offset by large increases in unit prices. The decrease in quantities purchased corresponded to reduced demand by SPPC's retail customers and reduced availability of gas for wholesale sales as a result of increased power plant consumption of gas. The higher unit prices were attributable to increased demand for gas in the Pacific Northwest and additional transportation fees.

For 2001, SPPC recorded significant Deferral of energy costs electric-net (for purchased power and fuel for generation) due to the implementation of deferred energy accounting beginning March 1, 2001. The current year amounts reflect the extent to which actual fuel and purchased power costs exceeded the fuel and purchased power costs recovered through current rates. SPPC did not utilize deferred energy accounting for its electric operations in 2000 or 1999.

Recovery of fuel expenses is administered under Nevada's deferred energy cost accounting procedures. Under the deferred energy procedure, changes in the costs of fuel and purchased power are reflected in customer rates through annual rate adjustments and do not affect income. See "Critical Accounting Policies," earlier, and Note 1 of "Notes to Financial Statements" for more information regarding deferred energy accounting.

In January 2000, after the expiration of a rate freeze that was in effect from 1997 through 1999, SPPC began deferring natural gas costs in excess of that allowed in the tariff for its gas LDC. The deferral increased significantly in 2001 due to higher gas costs incurred by SPPC, as discussed in "Gas Purchased for Resale," above.

SPPC's AFUDC is lower in 2001 because of adjustments to amounts assigned to specific components of facilities that were completed in different periods offset by an increase in the AFUDC rate. AFUDC for 2000 is higher than 1999 because of an AFUDC rate increase in 2000 and a $2.3 million adjustment in 1999 to reverse amounts previously charged to AFUDC.

Other operating expense increased in 2001 compared to 2000 due to a $7 million larger addition to the provision for uncollectible customer accounts than in 2000, and a $3.5 million reserve provision established as a result of AB
369. Additionally, there were increased expenses related to the start-up of the Pinon Gasifier in 2001. Other operating expense for 2000 was higher due to an increase in the provision for uncollectible accounts offset, in part, by reduced labor and benefit costs as a result of merger efficiencies and unfilled vacancies.

Maintenance costs in 2001 were higher due to additional turbine repairs and no major overhauls in 2000 at Valmy. There was also a shift from divestiture in 2000 to maintenance activities in 2001 at Tracy as well as unplanned maintenance on the diesel generators. Maintenance expense for 2000 decreased from 1999 as a result of fewer outages and lower plant maintenance expenses.

Depreciation and amortization was higher in 2001 than 2000 due to an increase in plant-in-service. Depreciation and amortization decreased in 2000 from 1999 because of computer software that was fully amortized in 1999.

As a result of recorded income for continuing operations for 2001, SPPC incurred income tax expense. Due to a net loss from continuing operations, SPPC recorded an income tax benefit for 2000. See Note 10 of "Notes to Financial Statements" for additional information regarding the computation of income taxes.

SPPC'S interest charges on long-term debt were higher in 2001 than 2000, primarily due to the issuance of $320 million of its General and Refunding Mortgage bonds in May 2001. Interest charges on long-term debt were higher in 2000, as a result of increased average long-term debt balances compared to 1999, including the June 2000 issuance of $200 million of variable rate notes.

SPPC'S interest charges-other decreased in 2001 compared to 2000 due to a decrease in commercial paper balances in 2001. For the year 2000, these interest charges-other were comparable to 1999.

SPPC's other income (expense) - net improved in 2001 due primarily to the recognition in the current year of carrying charges on deferred fuel and purchased power balances pursuant to AB 369. SPPC's other income (expense)-net declined in 2000 mainly due to the reclassification of lease expenses for SPPC's main offices.

Income from operations of the water business decreased in 2001 as a result of the sale of the water business on June 11, 2001, prior to the seasonal increase in revenues resulting from higher water send-out. Income from operations of the water business increased in 2000 due primarily to higher revenues, which resulted from both customer growth and to a lesser extent higher usage per customer.

Liquidity and Capital Resources

SPPC's net cash flows during 2001 were comparable to 2000. For 2001, an increase in net cash flows from investing activities was substantially offset by a decrease in net cash flows from operating activities. The increase in net cash flows from investing activities resulted from the sale of the assets of SPPC's water business. The decrease in cash flows from operating activities resulted substantially from the payment of significantly higher energy and resale natural gas costs. These uses of cash flows were partially offset by a decrease in accounts payable in 2001. The decrease in cash flows from financing activities was due to reduced reliance on commercial paper in 2001 and the retirement of preferred stock as described in Note 8 to the Financial Statements offset, in part, by capital contributions from SPR.

SPPC's net cash flows increased in 2000 compared to 1999. The net increase in cash resulted from less cash used in investing activities and more cash provided by financing activities. The decrease in cash used for investing activities was primarily due to SPPC's 1999 acquisition of General Electric Capital Corporation's interest in Pinon Pine Company L.L.C. Cash flows from financing activities increased slightly compared to the prior year due to the retirement of preferred stock in 1999. See Note 8 (Preferred Stock and Preferred Trust Securities) for information concerning the preferred stock retirement.

As discussed in "Construction Expenditures and Financing" and "Capital Structure" below, SPPC will have capital requirements for construction costs and for the repayment of maturing short-term and long-term debt during 2002 totaling approximately $189 million, which SPPC will need to fund through a combination of (i) internally generated funds, (ii) the issuance of short-term debt, and
(iii) capital contributions from SPR.

SPPC's primary source of short-term liquidity has been its commercial paper program, pursuant to which it sells commercial paper of varying maturities through dealers to institutional purchasers of commercial paper. SPPC's current program permits the sale of up to $150 million of commercial paper on a revolving basis. As of December 31, 2001, SPPC had $46.5 million of commercial paper outstanding, representing all of SPPC's short-term debt as of that date. As is customary for an A2/P2 commercial paper issuer, SPPC's commercial paper program requires that SPPC maintain a back-up credit facility in the event that SPPC is unable to sell additional commercial paper to pay off outstanding commercial paper due to conditions within the commercial paper market or due to a downgrade in the credit rating of SPPC's commercial paper. Accordingly, if there ever were an event of default under or cancellation or termination of the back-up credit facility, SPPC would not be able to issue commercial paper until SPPC obtained another back-up credit facility or until the default were waived or cured.

As discussed in "Capital Structure" below, SPPC has a Credit Agreement with a number of banks which matures on November 28, 2002. Although this facility may be used to provide liquidity for general corporate purposes, it has been used primarily by SPPC to back up its commercial paper program. The Credit Agreement

63

contains a number of restrictive covenants including restrictions on liens, sales of assets, mergers, and sale and leaseback transactions. The Credit Agreement also contains financial covenants requiring that SPPC maintain:

. a ratio of (i) Total Indebtedness to (ii) the sum of Total Indebtedness and Shareholders Equity that does not exceed 0.60:1 as of the last day of each fiscal quarter.
. a Consolidated Interest Coverage Ratio of not less than 2.0:1 calculated as of the last day of each fiscal quarter for the preceding four consecutive fiscal quarters.

As of December 31, 2001, SPPC was in compliance with these financial covenants.

The borrowing costs under the Credit Agreement are at a variable interest rate consisting of a spread over LIBOR or an alternate base rate that is based upon a pricing grid tied to the credit rating on SPPC's senior unsecured long-term debt. SPPC had no borrowings outstanding under the Credit Agreement as of December 31, 2001. On or before the maturity date of the Credit Agreement, SPPC currently intends to either renew or replace the Credit Agreement.

The Credit Agreement is currently unsecured. However, SPPC will be required to secure the Credit Agreement through the issuance of General and Refunding Mortgage bonds to the lenders in the event that the credit rating on SPPC's senior unsecured long-term debt is downgraded (i) by Moody's Investors Service, Inc. to Baa3 or lower or (ii) by Standard & Poor's Ratings Group to BB+ or lower. The Credit Agreement requires SPPC to maintain sufficient capacity under its General and Refunding Mortgage Indenture to satisfy this collateral requirement.

SPPC and NPC are currently negotiating receivables purchase facilities, in an aggregate principal amount not to exceed $200 million, that are expected to be finalized by the end of first quarter 2002. Under the proposed facilities, SPPC and NPC would each sell receivables in a true sale to special purpose entities that would in-turn sell those assets to a commercial paper conduit that would pay for the purchase of the assets by issuing commercial paper. These facilities will be used to provide additional liquidity for working capital and general corporate purposes in addition to SPPC's existing commercial paper program. SPPC expects the facility to be accounted for in compliance with SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." The special purpose entities will be wholly owned subsidiaries and their financial positions and results of operations will be reflected in the consolidated financial statements of SPR, NPC, and SPPC.

SPPC's first mortgage indenture creates a first priority lien on substantially all of SPPC's properties in Nevada and California. As of December 31, 2001, $509.7 million of SPPC's first mortgage bonds were outstanding. Although the first mortgage indenture allows SPPC to issue additional mortgage bonds on the basis of (i) 60 percent of net utility property additions and/or
(ii) the principal amount of retired mortgage bonds, SPPC agreed in its General and Refunding Mortgage Indenture that it would not issue any additional first mortgage bonds.

SPPC's General and Refunding Mortgage Indenture creates a lien on substantially all of SPPC's properties in Nevada that is junior to the lien of the first mortgage indenture. As of December 31, 2001, $320 million of SPPC's General and Refunding Mortgage bonds were outstanding. Additional securities may be issued under the General and Refunding Mortgage Indenture on the basis of (i) 70 percent of net utility property additions, (ii) the principal amount of retired General and Refunding Mortgage bonds and/or (iii) the principal amount of first mortgage bonds retired after delivery to the indenture trustee of the initial expert's certificate under the General and Refunding Mortgage Indenture. At December 31, 2001, SPPC had the capacity to issue approximately $416 million of additional General and Refunding Mortgage bonds. However, the financial covenants contained in the Credit Agreement described above may limit SPPC's ability to issue additional General and Refunding bonds or other debt.

64

SPPC also has the ability to release property from the liens of the two mortgage indentures on the basis of net property additions, cash and/or retired bonds. To the extent SPPC releases property from the lien of its General and Refunding Mortgage Indenture, it will reduce the amount of bonds issuable under that indenture.

SPPC's estimated cash construction expenditures for 2002 through 2006 are $556 million. SPPC estimates that 29% of its 2002 cash expenditures (approximately $40 million) will be provided by the issuance of short-term debt and parent contributions. In 2002, SPPC expects to pay all of its net income in dividends to SPR and to receive $60 million of capital contribution from SPR.

Cash provided by internally generated funds during 2002 assumes full recovery of deferred energy over three years; and assumes general rate increases approved as filed and effective mid-year. To the extent that the PUCN finds that any of SPPC's deferred energy costs resulted from imprudent purchases, the PUCN will not permit that amount to be recovered through higher rates, and an equivalent amount of SPPC's deferred energy cost asset will be required to be written off. A material write-off of deferred energy costs would have a material adverse affect on the future results of operations of SPPC and could cause SPPC's securities to be downgraded by the rating agencies and make it significantly more difficult to finance operations, and buy fuel and purchased power from third parties. Also see Construction Expenditures and Financing (SPR Consolidated) earlier.

Capital Structure

As of December 31, 2001, SPPC had short-term debt outstanding of $46.5 million comprised entirely of commercial paper.

On November 29, 2001, SPPC put into place a $150 million unsecured revolving credit facility replacing an existing $250 million credit facility, which may be used for working capital and general corporate purposes, including commercial paper backup. This new credit facility requires SPPC to issue general and refunding mortgage bonds to secure this credit facility in the event of a decline in SPPC's senior unsecured debt rating. This facility will expire on November 28, 2002.

SPPC's actual capital structure at December 31, 2001, and 2000 was as follows (dollars in thousands):

PURCHASED POWER PROCUREMENT (NPC and SPPC)

Traditionally, the Utilities obtained purchased power through annual and monthly Requests for Proposals ("RFPs") to electric suppliers. Over the past few years, structural and competitive changes in the energy markets have decreased the responsiveness of potential suppliers to the Utilities' RFPs. As a result of the market conditions in late 1999, the Utilities modified their procurement practices to rely less on the formal RFP process and more on the broker market. Brokers connect buyers and sellers in order to obtain optimal pricing for both sides. In October 1999, the Utilities established and utilized a timed procurement strategy in order to obtain a targeted percentage of their calculated purchased power requirement for procurement in the forward markets each month, following an overall trend of procuring power closer to the time of delivery. The timed procurement strategy was implemented at a time when the PUCN had ordered the Utilities to sell their generation plants in anticipation of retail competition and when it was still unclear what role the Utilities would play as a provider of last resort.

As the price of purchased power escalated in the late Spring of 2000 and serious concerns developed regarding the availability of purchased power in California and throughout the western United States, the

66

Utilities began accelerating and extending their timed procurement strategies to fill summer peak requirements for 2001 and 2002. In an effort to mitigate the higher costs for 2001 energy procurement at the height of the crisis and to insure availability of electricity to the Utilities' customers, the Utilities entered into forward agreements covering 2001 and 2002 in order to take advantage of the then lower pricing for 2002 purchases. The Utilities are currently working with major regional suppliers seeking bids to blend some of their existing forward contract prices (for deliveries in 2002 through 2005) to smooth out recent spikes in forward contract prices and to reduce overall purchased power costs for deliveries in 2002. At this time the Utilities cannot predict the likelihood of success of these efforts.

The Utilities continued to use the monthly RFP process in 2001, with the exception of the months of March through September for NPC. During the months of March through September, NPC had already secured purchased power resources such that it could rely on the spot market for its remaining power requirements.

In NPC's Refiled 2000 Resource Plan (PUCN Docket No. 01-7016) and SPPC's 2001 Resource Plan (PUCN Docket No. 01-7004), the Utilities set forth their base long-term procurement strategy which has since been modified to include obtaining up to 300 MW for NPC and 250 MW for SPPC of firm, baseload energy (seven days a week, twenty four hours a day) beginning January 1, 2004, with up to 500 MW of intermediate and peaking power purchases for delivery in the second and third quarter of each year.

The Utilities' purchased power procurement strategy involves an analysis of the Utilities' energy requirements to meet the needs of their retail and FERC jurisdictional loads. Net energy requirements are determined by subtracting already secured resources, including power plant generation, cogeneration facilities and previously purchased power contracts, from the Utilities' forecasted energy requirements. Once the net energy requirements are established, future energy prices are analyzed, using the forward market as the best predictor of future prices.

The net energy requirements and applicable pricing data are presented to the Utilities' Risk Management Committee ("RMC") which analyzes these requirements, reviews alternative purchasing strategies and provides guidance on the timing and quantity of purchases. See Item 7A, Quantitative and Qualitative Disclosures About Market Risk for additional discussion regarding the RMC's role and the application of risk management policies. The RMC regularly reviews updated transaction information, available secured energy resources and power requirements in order to determine secured resources requirements as well as total power requirements.

Short Term Power Procurement Strategy

The Utilities' short term power procurement strategy involves both day-ahead (next day through the end of the current month) and real-time (next hour through the end of the current day) activities that require buying, selling and scheduling power resources to determine the most economical way to produce or procure the power resources needed to meet the retail customer load. After connecting generation units to the system, the Utilities dispatch the generation output based on the comparative economics of generation versus spot-market purchase opportunities and determine the amount of excess capacity, which is then sold on the wholesale market, or the amount of deficiency capacity, which must be procured on an hourly basis.

The day-ahead resource coordination begins with an analysis of projected loads and existing resources. Firm forward take-or-pay contracts are scheduled and counted towards meeting the capacity needs of the day being pre-scheduled. Any deficiency in the projected operating reserve for the next day, after consideration of available internal generation resources is met by additional firm purchased power resources. The day-of resource coordination involves minimizing system production costs each hour by either changing the generation output or buying needed power/selling excess power in the wholesale market. Any sale of excess power priced above the incremental cost of producing such power reduces the net production cost of operating the electrical

67

system and thereby benefits the end use customer. The Utilities endeavor to reduce the electrical systems' net production cost by selling the available excess power resources.

Real-time resource coordination requires an hourly determination of whether to run generation or purchase power in order to achieve the lowest production costs by calculating the projected incremental or decremental cost of generation required to meet the forecast load in comparison to obtaining power in the wholesale power market. In the event that committed generators suffer a forced outage that is expected to last through the remaining monthly period, the operating cost of the next available generation resource is compared to purchase power options to determine the lowest cost option.

Term Power Procurement Strategy

The majority of the Utilities' purchased power resources are secured through term transactions (transactions of greater than one month). To coordinate fuel and purchase power resources, the Utilities analyze their existing portfolios of fuel and purchased power and the projected electrical system loads for the period under consideration. Existing contracts for natural gas and purchased power are compared to the projected load profile to determine if there are adequate resources to cover the peak loads plus reasonable reserves.

If monthly resources are insufficient to cover the average daily peak plus 7%, the cost of generating additional electrical energy is compared to the available purchase power cost to determine the lowest cost option for securing additional power resources. If the monthly resources exceed the requirements of the average daily peak plus 7%, the Utilities analyze whether it is more cost-efficient to sell off power and power resources or to keep the excess power to cover generation contingencies and deal with the excesses on a daily or hourly basis.

Hedging Transactions

Over the last two years the Utilities have used hedges to reduce price and commodity risk for future purchases by executing contracts at so-called "liquid" trading points. A liquid trading point is a hub where significant volumes of energy are freely purchased and sold amongst many parties at a heavy volume so that one particular transaction has no discernable effect on the market price of energy at that trading point. The hedged purchases are either delivered to the Utilities' service territories to service their customers or, if the hedged purchase is not needed to fulfill power requirements, resold in the liquid market depending upon the size of the load, the status of internal generation, and the market price at time of delivery.

A typical hedge transaction involves the purchase or sale of power at one of the major trading hubs where prices are highly correlated to the ultimate point of delivery. The following is an illustration of a typical hedging transaction for NPC. NPC's main point of interconnection with the Western System Coordinating Council grid is at Mead Substation, Nevada. If NPC seeks to purchase 25 MW of power for delivery on a specified future date, NPC can purchase energy from other major trading hubs that are highly correlated to Mead, such as Palo Verde, Arizona, thereby assuring the availability of 25 MW electricity on that date to meet anticipated loads. By purchasing power at Palo Verde, NPC is also protected from the risk of market participants knowing that NPC must make a purchase and the resultant increase in prices at NPC's primary point of delivery. Once it makes the purchase at Palo Verde, NPC will continually monitor whether other power might be available at a lower total cost, including the cost of transmitting the electricity to NPC's system. If NPC finds an opportunity to purchase the same amount of power at delivery hubs closer to Mead, such as Pinnacle Peak Substation in Arizona, for a lower total cost than taking delivery of the original purchase at Palo Verde, NPC will sell its 25 MW position at Palo Verde and purchase the 25 MW position for delivery at Pinnacle Peak. Shortly before the date of delivery, NPC may have an opportunity to procure yet another source of power that will deliver 25 MW more cheaply, on a total cost basis, directly to Mead Substation. NPC would

68

therefore sell the 25 MW position at Pinnacle Peak and purchase the 25 MW position for delivery at Mead Substation.

In the above example, NPC will record a total of 75 MW of purchased power expense, 50 MW of wholesale power sales and 25 MW of retail sales, all of which are related to meeting the same 25 MW load requirement. This series of transactions is designed to acquire power at the lowest feasible total cost while at the same time ensuring that the basic commodity will be available on the date needed. At no time are the Utilities trading power on a speculative basis. Any savings in costs achieved by such a series of transactions will lower the Utility's overall costs for purchased power and therefore reduce the Utility's deferred energy account balance.

REGULATION AND RATE PROCEEDINGS

Nevada Matters (NPC and SPPC)

The Utilities are subject to the jurisdiction of the PUCN and, in the case of SPPC, the California Public Utility Commission (CPUC) with respect to rates, standards of service, siting of and necessity for, generation and certain transmission facilities, accounting, issuance of securities and other matters with respect to electric distribution and transmission operations. NPC and SPPC submit integrated resource plans to the PUCN for approval.

Under federal law, the Utilities are subject to certain jurisdictional regulation, primarily by the FERC. The FERC has jurisdiction under the Federal Power Act with respect to rates, service, interconnection, accounting, and other matters in connection with the Utilities' sale of electricity for resale and interstate transmission. The FERC also has jurisdiction over the natural gas pipeline companies from which the Utilities take service.

As a result of regulation, many of the fundamental business decisions of the Utilities, as well as the rate of return they are permitted to earn on their utility assets, are subject to the approval of governmental agencies.

As with other utilities, NPC and SPPC are subject to federal, state and local regulations governing air, water quality, hazardous and solid waste, land use and other environmental considerations. Nevada's Utility Environmental Protection Act requires approval of the PUCN prior to construction of major utility, generation or transmission facilities. The United States Environmental Protection Agency (EPA), Nevada Division of Environmental Protection (NDEP), and Clark County Health District (CCHD) administer regulations involving air quality, water pollution, solid, hazardous and toxic waste. SPR's Board of Directors has a comprehensive environmental policy and separate board committee that oversees NPC, SPPC, and SPR's corporate performance and achievements related to the environment.

Nevada Legislation

On April 18, 2001, the Governor of Nevada signed into law AB 369. The provisions of AB 369 include a moratorium on the sale of generation assets by electric utilities, the repeal of electric industry restructuring, and a reinstatement of deferred energy accounting for fuel and purchased power costs incurred by electric utilities. The stated purposes of this emergency legislation were, among others, to control volatility in the price of electricity in the retail market in Nevada, and to ensure that the Utilities have the necessary financial resources to provide adequate and reliable electric service under present market conditions. To achieve these purposes, AB 369 allows the Utilities to recover in future periods their current costs for wholesale power and fuel, which have risen dramatically over the past year. Deferred energy accounting will have the effect of delaying additional rate increases to consumers until the second quarter of 2002 while, at the same time, providing a method for the Utilities to recover their increased costs for fuel and purchased power. Set forth below is a summary of key provisions of AB 369.

Generation Divestiture Moratorium

AB 369 prohibits all divestiture of generation assets by electric utilities until July 2003. After January 1, 2003, NPC or SPPC may seek PUCN permission to sell one or more generation assets with the sale to be effective on or after July 1, 2003. The PUCN may approve the request to divest only if it finds the transaction to be in the public interest. The PUCN may base its approval of the request upon such terms, conditions, or modifications as it deems appropriate.

AB 369 directs the PUCN to take all steps necessary to obtain federal approval for the prohibition on divestiture and to vacate any of its own orders that had previously approved generation divestiture transactions.

Deferred Energy Accounting

AB 369 required the Utilities to use deferred energy accounting for their respective electric operations beginning on March 1, 2001. The intent of deferred energy accounting is to ease the effect of fluctuations in the cost of purchased power and fuel. See Note 3 to the Financial Statements for a discussion of the deferred energy accounting provisions of AB 369.

Transition of Rates to Deferred Energy Accounting

All rates in effect on April 1, 2001, including the cumulative increases under the Global Settlement and the CEP Riders, remain in effect until the PUCN issues final orders on future general and initial deferred energy rate applications. (See "Required Filings," below). No further applications can be made for the Fuel and Purchased Power (F&PP) riders that were part of the July 2000 Global Settlement described in SPR's Annual Report on Form 10-K for the year ended December 31, 2000.

The Utilities are not permitted to recover any shortfall incurred before March 1, 2001, resulting from the difference between actual fuel and purchased power costs and the rates permitted by the Global Settlement. Although the F&PP riders were in effect during this period, the riders were based on trailing 12-month average costs and were subject to caps and, therefore, did not allow the Utilities full recovery for fuel and purchased power costs due to the rapid rise in energy prices.

AB 369 prohibits the PUCN from taking any further action on the CEP, and provides that, except for the CEP Rider rate increases put in effect on April 1, 2001, the CEP will be deemed to have been withdrawn by the Utilities. Additionally, approximately $20 million of revenue collected by the Utilities based on the CEP before

71

April 1, 2001 was credited to the deferred energy accounts, which caused the accounts to start in an over-collected position.

Required Filings

The Utilities have both filed a general rate application and a deferred energy application on the dates listed below:

                                            General Rate Case                      Deferred Energy Filing
                                            -----------------                      ----------------------
                                       File Date         Effective Date         File Date          Effective Date
Nevada Power Company                 Oct. 1, 2001         April 1, 2002        Dec. 1, 2001         April 1, 2002
Sierra Pacific Power Company         Dec. 1, 2001          June 1, 2002        Feb. 1, 2002          June 1, 2002

In connection with clearing the Utilities' deferred energy accounts, the PUCN must investigate and determine whether the Utilities' rates that went into effect on March 1, 2001, pursuant to the CEP, are just and reasonable and reflect prudent business practices. The rates in effect on April 1, 2001, remain in effect until the PUCN issues final orders on the general and initial deferred energy rate applications referred to above. The PUCN is prohibited from adjusting rates during this time period unless an adjustment is absolutely necessary to avoid a finding that the rates are confiscatory and, therefore, in violation of the United States or Nevada Constitutions. If adjustments are necessary, they may only be made to the extent necessary to avoid an unconstitutional result.

After the initial general rate applications described above, each Utility will be required to file future general rate applications at least every 24 months.

See "Nevada Power Company General Rate Case," later, for a discussion of NPC's general rate application filed on October 1, 2001 and "Nevada Power Company Deferred Energy Case," later, for a discussion of NPC's deferred rate application filed on November 30, 2001.

See "Sierra Pacific Power Company General Rate Case," later, for a discussion of SPPC's general rate application filed on November 30, 2001 and "Sierra Pacific Power Company Deferred Energy Case," later, for a discussion of SPPC's deferred rate application filed on February 1, 2002.

Restrictions on Mergers and Acquisitions

AB 369 imposes certain restrictions on mergers and acquisitions involving Nevada electric utilities. In particular, the PUCN may not approve a merger or acquisition involving an electric utility unless the utility complies with the generation divestiture provisions of AB 369.

In addition, AB 369 includes provisions that would have significantly affected the required regulatory approvals for the proposed acquisition of PGE from Enron. On April 26, 2001, Enron and SPR terminated, by mutual agreement, the proposed purchase and sale of PGE.

AB 369 also provides that if an electric utility holding company acquires an interest in an out-of-state public utility prior to July 1, 2003, each electric utility in which the holding company holds a controlling interest shall not be entitled to the benefit of deferred energy accounting. Thus, in the event that SPR acquires an out-of-state public utility, NPC and SPPC would lose the ability to utilize deferred energy accounting.

72

Repeal of Electric Industry Restructuring

AB 369 repeals all statutes authorizing retail competition in Nevada's electric utility industry and voids any license issued to an alternative seller in connection with retail electric competition.

Other Legislation

SB 372, which increased renewable energy portfolio requirements, was enacted in the 2001 Nevada legislative session. Renewable resources include biomass, wind, solar, and geothermal projects. In 2003, the Utilities will be required to purchase five percent of their energy from renewable resources. These requirements increase to 15% by 2013. Prior law capped renewable energy requirements at one percent. Currently, SPPC obtains approximately nine percent of its energy from renewable resources, while NPC obtains less than one percent from renewables. SB 372 requires the PUCN to establish standards for renewable energy contracts, including prices and other terms and conditions. If sufficient renewable energy contracts that meet PUCN standards are not available, the Utilities will not be required to meet the portfolio requirements. All renewable energy contracts meeting PUCN standards will be recoverable in the deferred energy accounts.

The 2001 Nevada legislature passed another key piece of legislation for the Nevada energy industry, AB 661. AB 661 allows commercial and governmental customers with an average demand greater than 1 MW to select new energy suppliers. The Utilities would continue to provide transmission, distribution, metering and billing services to such customers. AB 661 requires customers wishing to choose a new supplier to receive the approval of the PUCN and meet public interest standards. In particular, departing customers must secure new energy resources that are not under contract to the Utilities, remaining customers or the utility cannot be negatively impacted by the departure, and the departing customers must pay any deferred energy balances. The PUCN has adopted regulations prescribing the criteria that will be used to determine if there will be negative impacts to remaining customers or the utility. Certain limits are placed upon the departure of NPC customers until 2003; most significantly, the amount of load departing is limited to approximately 1100 MW in peak conditions. AB 661 permits customers to file applications with the PUCN beginning in the fourth quarter of 2001. Customers must provide 180-day notice to the Utilities and could begin to receive service from new suppliers by mid-2002. On January 10, 2002, an approximately 130 MW SPPC customer submitted an application to the PUCN under AB 661. The customer, SPPC, and PUCN staff are negotiating a stipulation regarding settlement of the terms and conditions under which this customer will be permitted to procure energy from an alternative source other than SPPC. The terms and conditions of the stipulation are expected to comply with the provisions of AB 661 in that SPPC and its remaining customers will not be negatively impacted by the customer's departure. A hearing on the stipulation has been set for March 20, 2002.

AB 661 also contains new electric and gas energy surcharges for low-income assistance and weatherization programs. These surcharges are recoverable directly from customers as separate line items on their bills with the Utilities remitting collected surcharges to the PUCN. Various state agencies will administer the disposition of the funds.

Nevada Power Company General Rate Case (NPC)

On October 1, 2001, NPC filed an application with the PUCN seeking an electric general rate increase. This application was mandated by AB 369, which was enacted by the Nevada legislature in April 2001. On December 21, 2001, NPC filed a Certification to its general rate filing updating costs and revenues pursuant to Nevada regulations. In the certification filing, NPC requested an increase in its general rates charged to all classes of electric customers designed to produce an increase in annual electric revenues of $22.7 million, which is an overall 1.7% rate increase. The application also seeks a return on common equity ("ROE") for Nevada Power's total electric operations of 12.25% (a reduction from NPC's last-authorized ROE for bundled electric

73

operations of 12.50%) and an overall rate of return ("ROR") of 9.30% (a reduction from NPC's last-authorized ROR for bundled electric operations of 10.02%). Public hearings on NPC's general rate case began on February 4, 2002. Various parties have intervened in NPC's general rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, MGM/Mirage, and the Nevada Coalition Of Commercial Energy Consumers. The reduction of NPC's revenue requirements proposed by the intervenors ranges from $50 million to $107 million.

Nevada Power Company Deferred Energy Case (NPC)

On November 30, 2001, NPC filed an application with the PUCN seeking to clear deferred balances for purchased fuel and power costs accumulated between March 1, 2001 through September 30, 2001. This application was mandated by AB 369, which was enacted by the Nevada Legislature in April 2001. The application seeks to establish a Deferred Energy Accounting Adjustment ("DEAA") rate to clear accumulated purchased fuel and power costs of $922 million and spread the cost recovery over a not more than three-year period. It also seeks to recalculate the Base Tariff Energy Rate to reflect anticipated ongoing purchased fuel and power costs. The total rate increase resulting from the DEAA would amount to 21%. NPC has proposed an alternate plan in which full recovery of the deferred balance would be amortized over a period greater than three years, but not to exceed six years. Public hearings began March 4, 2002. Various parties have intervened in NPC's deferred energy rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, MGM/Mirage, the Southern Nevada Water Authority, the Nevada Energy Buyers Group, and the Nevada Coalition Of Commercial Energy Consumers. The disallowance of NPC's deferred energy balance that is proposed by the intervenors ranges from $85 million to $980 million. The disallowance of a significant amount of NPC's deferred energy costs could result in NPC becoming insolvent. Some intervenors have argued that disallowance of NPC's deferred energy costs would be in the best interests of ratepayers based on speculation that some of the deferred energy costs could be avoided under bankruptcy laws if NPC were to become subject to bankruptcy proceedings.

Sierra Pacific Power Company General Rate Case (SPPC)

On November 30, 2001, SPPC filed an application with the PUCN seeking an electric general rate increase. This application was mandated by AB 369, which was enacted by the Nevada Legislature in April 2001. On February 28, 2002, SPPC filed a certification to its general rate filing, updating costs and revenues pursuant to Nevada regulations. In the certification filing, SPPC requested an increase in its general rates charged to all classes of electric customers, which were designed to produce an increase in annual electric revenues of $15.9 million representing an overall 2.4% rate increase. The application also seeks an ROE for SPPC's total electric operations of 12.25% (an increase from SPPC's last authorized ROE for bundled electric operations of 12.0%) and an overall ROR of 9.42% (a reduction from SPPC's last authorized ROR for bundled electric operations of 10%). Public hearings for SPPC's general rate case are scheduled to begin on April 8, 2002. Various parties have intervened in SPPC's general rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, and Barrick Goldstrike Mines, among others. Intervenor testimony will not be filed until March 22, 2002.

Sierra Pacific Power Company Deferred Energy Case (SPPC)

On February 1, 2002, SPPC filed an application with the PUCN seeking to clear deferred balances for purchased fuel and power costs accumulated between March 1, 2001 and November 30, 2001. This application was mandated by AB 369. The application seeks to establish a DEAA rate to clear accumulated purchased fuel and power costs of $205 million and spread the cost recovery over a not more than three-year period. It also seeks to recalculate the Base Tariff Energy Rate to reflect anticipated ongoing purchased fuel and power costs. The total rate increase resulting from the DEAA would amount to 9.8%. SPPC has proposed an alternate plan in which full recovery of the deferred balance would be amortized over a period greater than three years, but not to exceed six years. Public hearings are scheduled to begin in April 2002. Various parties have intervened in SPPC's deferred energy rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, and Barrick Goldstrike Mines, among others. Intervenor testimony will not be filed until April 22, 2002. The disallowance of a significant amount of SPPC's deferred energy costs could result in SPPC becoming insolvent.

74

Resource Plans (SPPC, NPC)

On July 2, 2001, SPPC filed its electric resource plan for the period of 2001-2020. On July 9, 2001, NPC filed its amended electric resource plan for the period of 2000-2019. The plans include scenarios to meet the electric needs of customers while sustaining reliable electric systems. The integrated resource plans evaluate resources to be used to meet forecasted loads. Resource options considered include new transmission lines to access energy markets, construction of generation facilities, power purchases from IPP's under short- and long-term agreements, and conservation programs. On October 18, 2001, the PUCN approved NPC's amended resource plan. On August 2, 2001, a pre-hearing conference was held on SPPC's resource plan and procedural orders were established. Public hearings on SPPC's plan were held in late October, and on November 1, 2001, the PUCN issued an order approving and adopting SPPC's plan.

PUCN Rulemaking for Assembly Bill 661 (SPPC, NPC)

The PUCN opened an investigatory and rulemaking docket to implement the provisions of AB 661. The PUCN has scheduled a workshop to receive comments regarding proposed regulations. These regulations concern eligible customers purchasing new electric resources from suppliers other than SPPC or NPC. A public hearing regarding the regulation was held on October 30, 2001. On November 26, 2001, the PUCN approved the regulations.

Optional Conservation Service (NPC, SPPC)

On April 19, 2001, the PUCN approved new NPC and SPPC electric rates for Optional Conservation Service (Schedule OC). Schedule OC allows the Utilities to request customers with demand greater than 1 MW to voluntarily curtail their load when there is an economic or system need for capacity and energy. Customers who curtail load will receive a billing credit.

Parallel Generation Tariffs (NPC, SPPC)

On May 11, 2001, the Utilities filed with the PUCN revisions to existing tariffs that will allow customers to interconnect standby generators in parallel with the Utilities' facilities. These changes will allow customers meeting specific requirements to utilize their standby generators in support of the Optional Conservation Service tariffs during times of power shortages or higher prices. On August 3, 2001, the PUCN approved the revisions.

Finance Authority (NPC, SPPC)

On September 20, 2001, the PUCN approved the June 19, 2001 applications by the Utilities for authority to issue long or short-term debt on either a secured or unsecured basis in an aggregate amount not to exceed $200 million for NPC and $100 million for SPPC through the end of 2002. NPC has issued all of its $200 million of authorized debt. SPPC has not issued any debt under this authority and has the full amount of the $100 million of authorized debt available for future issuances. On September 20, 2001, the PUCN also approved the Utilities' June 19, 2001 applications to amend an order issued by the PUCN allowing each of the Utilities to issue unsecured short-term promissory notes in an amount not to exceed $250 million through the period ending December 31, 2001. In the applications, the Utilities requested that the PUCN amend its previous order to provide the Utilities with the flexibility to issue secured promissory notes in addition to, or in lieu of, the authorized unsecured promissory notes.

On October 1, 2001, NPC and SPPC each filed an application with the PUCN requesting authority to issue secured or unsecured promissory notes in aggregate amounts not to exceed $250 million through December 31, 2004. On October 9, 2001, the Utilities filed amended applications reducing the time period to

75

December 31, 2003. On November 29, 2001, the PUCN issued a compliance order approving the requests. Currently, NPC has $50 million and SPPC has $100 million of short-term debt authority remaining from these PUCN authorizations.

Natural Gas Rate Increase (SPPC)

On June 29, 2001, SPPC filed with the PUCN a Purchase Gas Adjustment (PGA) seeking recovery of $41.4 million in accumulated, unrecovered purchased gas expenses, and an increase in the going-forward rate to $.71 per therm. Public hearings were held on October 22 and 23, 2001. On November 5, 2001, the PUCN granted SPPC's application and approved recovery of the entire $41.4 million accumulated deferred balance over a three-year period and an increase in the going-forward rate to $.6648 per therm. Any over or under-recovery of future energy costs will be the subject of a future PGA application. SPPC will file its next PGA on July 1, 2002.

SPR and NPC Merger (NPC and SPPC)

The merger between SPR and NPC was finalized on July 28, 1999. As part of the conditions for the merger, the Utilities were each required to divest all generation assets and file a general rate case unbundling costs. In May 1999, the Nevada Legislature passed SB 438, which modified the electric restructuring statutes. The Utilities filed general rate cases, unbundling costs and filed distribution rates for an unregulated market. However, in April of 2001 the Nevada Legislature passed AB 369, discussed earlier, which repealed the condition that the Utilities divest their generation assets and placed a moratorium on the sale of any generation assets until July 2003. AB 369 also repealed electric restructuring (deregulation).

FERC Matters (NPC and SPPC)

Price Mitigation Plan

On June 19, 2001, the FERC adopted a price mitigation plan applicable to spot market wholesale power sales in California and throughout the western United States during the period June 20, 2001 through September 30, 2002. The price mitigation plan establishes a mechanism with which to determine the maximum amount that may be charged for power sold during this period. The intent of the mitigation plan is to simulate the price that might be charged for electricity sold under competitive market conditions. Sellers that do not wish to establish rates on the basis of this price mitigation plan may propose cost-of-service rates covering all of their generating units in the WSCC for the duration of the mitigation plan. Although the Utilities are not able to predict at this time the long-term effect that the FERC price mitigation plan and other market developments may have on their results of operations, management believes that, under certain market conditions, the FERC plan adversely affects the availability of spot market power to the Utilities and reduces the price at which the Utilities can sell power on the wholesale market. Another potential result from these price mitigation measures could be the delay and/or cancellation of proposed power plants throughout the western United States. If these results occur, the long-term supply of energy could be reduced. Numerous parties, including NPC and several northwest utilities, appealed the June 19 and July 25, 2001 orders from the FERC to the District of Columbia Court of Appeals on the basis that the price caps are unfair to electric customers who reside outside of California. In a report to Congress on January 31, 2002, the FERC said the price mitigation plan had little if any influence on prices at which Western utilities were able to resell power. SPR is not persuaded by the FERC's report and continues to believe that the FERC's price caps have negatively impacted electric customers outside California. The parties to the appeal await action by the Court.

76

Regional Transmission Organization and Independent Transmission Company

NPC and SPPC are members of the utility groups that are forming a proposed regional transmission organization (RTO West) and a proposed independent transmission company (TransConnect).

In October 2000, RTO West submitted to the FERC a compliance filing and supplemental material, which provided details of the formation of the RTO. RTO West, as proposed, would be a non-profit independent system operator of the regional transmission grid, governed by an independent board of directors. This filing was made in compliance with FERC Order 2000, which required all investor-owned utilities in the United States who own interstate transmission to file a proposal to participate in an RTO or an explanation of efforts and plans to participate in an RTO. Also in October 2000, TransConnect submitted to the FERC a proposal to form a for-profit Independent Transmission Company which would become a member of RTO West.

On April 25, 2001, FERC gave preliminary approval for both RTO West and TransConnect. On November 13, 2001, TransConnect submitted a filing to FERC asking for preliminary approval of its proposed transmission rate structure, modified governance proposal, and transmission planning and expansion protocol. On December 1, 2001, RTO West submitted a status report on its development efforts to FERC in compliance with FERC's April 2001 order. Both organizations remain subject to approvals from state regulators and the board of directors of each member company.

The current filing utility members of RTO West are NPC, SPPC, Avista Corporation, British Columbia Hydro & Power Authority, Bonneville Power Administration (BPA), Idaho Power Company, The Montana Power Company, PacifiCorp, Portland General Electric, and Puget Sound Energy, Inc. The current filing utility members of TransConnect are NPC, SPPC, Avista Corporation, and Portland General Electric.

Wholesale Sales Tariffs

On March 13, 2001, the Utilities each filed an application for an order approving market-based rates. The market-based authority would apply to sales of electric energy and capacity outside of the Utilities' control areas. On May 11, 2001, SPPC and NPC received approval for market-based rates subject to a compliance order. SPPC's and NPC's compliance filing was accepted on August 10, 2001.

Alturas Intertie

Certain Northern California public power groups have challenged SPPC's filing with the FERC of the interconnection and operating agreements related to the Alturas Intertie in December 1998 and January 1999. The California groups alleged that the potential reduction in imports into California constitutes an impairment of reliability and therefore seek to force reductions in use of the Alturas Intertie during peak periods. SPPC (supported by Bonneville Power Administration and PacifiCorp) has filed testimony before the FERC that the Alturas Intertie does not adversely affect reliability and that, under the FERC's Order No. 888, customers in Nevada are entitled to compete with customers in California for transmission capacity in the Pacific Northwest on a first-come, first-served basis. The FERC staff has agreed with SPPC's position on this matter. The matter was tried to an Administrative Law Judge (ALJ) in April and May 2000. In 2001, the ALJ agreed with SPPC's position, but imposed a limitation on additional transfer capacity created by future upgrades to the system. The ALJ stated allocation of additional transfer capacity would require agreement among the parties. Both sides have appealed this decision to the full FERC.

77

California Matters (SPPC)

Rate Stabilization Plan

SPPC serves approximately 44,500 customers in California. On June 29, 2001, SPPC filed with the CPUC a Rate Stabilization Plan, which includes two phases. Phase One, which was also filed June 29, 2001, is an emergency electric rate increase of $10.2 million annually or 26%. If granted, the typical residential monthly electric bill for a customer using 650 kilowatt-hours would increase from approximately $47.12 to $60.12. On August 14, 2001, a pre-hearing conference was held, and a procedural order was established. On September 27, 2001, the Administrative Law Judge issued an order stating that no interim or emergency relief could be granted until the end of the "rate freeze" period mandated by the California restructuring law for recovery of stranded costs. In accordance with the judge's request, on October 26, 2001, SPPC filed an amendment to its application declaring the rate freeze period to be over.

Phase Two, which is scheduled to be filed with the CPUC in April 2002, will be a general rate case to recover costs for expenses other than fuel and purchased power. SPPC will also ask the CPUC to reinstate the Energy Cost Adjustment Clause, which would allow SPPC to file for periodic rate adjustments to reflect its actual costs for fuel and purchased power. Phase Two will also include a proposal pertaining to the termination of the 10% rate reduction mandated by AB 1890. On December 5 and 11, 2001 hearings on Phase One were held and on January 11, 2002, opening briefs were filed. Reply briefs were filed on January 25, 2002. A proposed draft decision is expected by the end of March 2002. SPPC will file Phase Two on April 1, 2002.

Distribution Performance-based Rate-making

Hearings on SPPC's distribution performance -based rate-making (PBR) proposal were held on April 2, 2001. An outline of the settlement reached by SPPC, the CPUC Office of Ratepayer Advocates, and The Utility Reform Network resolving all issues was presented during the hearing. On May 11, 2001, a formal joint settlement was submitted to the Administrative Law Judge. To date there has been no formal action on the filed joint settlement. On December 11, 2001, the Commission approved an order dismissing the application because of the pending emergency rate increase request and SPPC's plans to file a GRC. This decision approved parts of the joint settlement agreement and the record of the proceeding will be available for use in future proceedings before the Commission.

California Assembly Bill 6X

On January 18, 2001, the California Legislature passed Assembly Bill (AB) 6X. AB 6X modified Section 377 of California law restricting the sale of generation assets. AB 6X states that no facility for the generation of electricity owned by a public utility may be disposed of prior to January 1, 2006. Since SPPC is a public utility serving California customers, the sale of SPPC's generation assets was halted. The sale of the Mohave Generating Station, in which NPC has a 14% undivided interest, was also stopped because Southern California Edison is an operating partner of that facility.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SPR has evaluated its risk related to financial instruments whose values are subject to market sensitivity. Such instruments are fixed and variable rate debt, and preferred trust securities obligations, which were as follows on December 31, 2001, and 2000. Fair market value was determined using quoted market price for the same or similar issues or on the current rates offered for debt of the same remaining maturities.

Long-term debt (dollars in thousands):

COMMODITY PRICE RISK

SPR is exposed to commodity price risk primarily related to changes in the market price of electricity as well as changes in fuel costs incurred to generate electricity. See Purchased Power Procurement in Item 7, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, for a discussion of the Utilities' purchased power procurement strategies.

The Utilities' efforts to manage energy commodity (electricity, natural gas, coal and oil) price risk are governed by a Board of Directors approved Energy Risk Management Policy. That policy is augmented by an IT system to track any commodity price exposure. The Energy Risk Management Policy sets forth business objectives, organizational structure, performance metrics and operating requirements. The policy also establishes guidelines for the Risk Management Committee ("RMC"), which is responsible for providing management advice and recommendations on energy risk management related issues. The RMC met periodically throughout 2001.

The Utilities' commodity risk management program establishes a control framework based on existing commercial practices. The program creates common predefined risk parameters and delineates management responsibilities and organizational relationships. The program requires that transaction accounting systems and procedures be maintained for systematically identifying, measuring, evaluating and responding to the variety of risks inherent in the Utilities' commercial activities. The program's control framework consists of a disclosure and reporting mechanism designed to keep management fully informed of the operation's compliance with performance parameters.

The objective of the Utilities' energy risk management program is to help management exercise informed judgments on risk assessment and management. Supporting activities are designed:

80

. To provide management with a quantification of the Utilities' cash flow requirements for fuel and purchased power;

. To provide management with a quantification of the Utilities' cash flow sensitivity to movements in energy markets;

. To provide management with a quantification of the expected retail rate impact attributable to expenditures for fuel and purchased power;

. To provide management with estimates of the sensitivity of retail rates to movements in energy markets;

. To extract market pricing information that can be used in future decisions; and

. To help to optimize the output from the Utilities' generation assets.

On March 1, 2001, deferred energy accounting procedures were applied to the Utilities' electric operations. Such procedures had been in place for SPPC's gas distribution company. Deferred energy accounting facilitates the recovery of costs incurred while procuring fuel and purchased power for SPPC and NPC.

The Utilities also monitor and manage credit risk with their trading counterparties. As of December 31, 2001, the Utilities have outstanding transactions with over 40 energy and financial services companies. The Utilities had net credit risk with only eleven of their trading counterparties totaling approximately $2 million as of December 31, 2001.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of Sierra Pacific Resources
Reno, Nevada

We have audited the accompanying consolidated balance sheets and consolidated statements of capitalization of Sierra Pacific Resources and subsidiaries (the Company) and the separate unconsolidated balance sheets and statements of capitalization of Nevada Power Company (NPC) as of December 31, 2001 and 2000, and the related statements of income, comprehensive income, common shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2001. Our audit also included the consolidated and unconsolidated financial statement schedules listed in the Index at Item 14. These financial statements and financial statement schedules are the responsibility of the Company's and NPC's management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. 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, such financial statements present fairly, in all material respects, the consolidated financial position of the Company and the financial position of NPC as of December 31, 2001 and 2000, and the respective results of their operations and their 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 of America. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly in all material respects the information set forth therein.

NOTES TO FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies for both utility and non-utility operations are as follows:

General

The consolidated financial statements include the accounts of Sierra Pacific Resources (SPR) and its wholly-owned subsidiaries, Nevada Power Company (NPC), Sierra Pacific Power Company (SPPC), Tuscarora Gas Pipeline Company (TGPC), Sierra Pacific Communications (SPC), Lands of Sierra, Inc. (LOS), Sierra Energy Company dba e.three (e.three), Nevada Electric Investment Company (NEICO), Sierra Pacific Energy Company (SPE), Sierra Water Development Company (SWDC) and, Sierra Gas Holding Company (SGHC). All significant intercompany balances and intercompany transactions have been eliminated in consolidation. See Note 2 for additional information regarding the presentation of consolidated financial results pursuant to the 1999 merger of SPR and NPC.

NPC is an operating public utility that provides electric service in Clark County in southern Nevada. The assets of NPC represent 60% of the consolidated assets of SPR at December 31, 2001. NPC provides electricity to approximately 639,000 customers in the communities of Las Vegas, North Las Vegas, Henderson, Searchlight, Laughlin and adjoining areas. Service is also provided to Nellis Air Force Base and the Department of Energy at Mercury and Jackass Flats at the Nevada Test Site. The consolidated financial statements of SPR include the accounts of NPC's wholly owned subsidiaries, NVP Capital I and NVP Capital III.

SPPC is an operating public utility that provides electric service in northern Nevada and northeastern California. SPPC also provides natural gas service in the Reno/Sparks area of Nevada. The assets of SPPC represent 33% of the consolidated assets of SPR at December 31, 2001. SPPC provides electricity to approximately 315,000 customers in a 50,000 square mile service area including western, central and northeastern Nevada, including the cities of Reno, Sparks, Carson City, Elko, and a portion of eastern California, including the Lake Tahoe area. The consolidated financial statements of SPR include the accounts of SPPC's wholly owned subsidiaries, Pinon Pine Corporation, Pinon Pine Investment Company, GPSF-B, SPPC Funding LLC, and Sierra Pacific Power Capital I.

The Utilities' accounts for electric operations and SPPC's accounts for gas operations are maintained in accordance with the Uniform System of Accounts prescribed by the Federal Energy Regulatory Commission ("FERC").

TGPC is a partner in a joint venture that developed, constructed, and operates a natural gas pipeline serving the expanding gas market in the Reno area and certain northeastern California markets. TGPC accounts for its joint venture interest under the equity method. e.three provides comprehensive energy services in commercial and industrial markets on a regional basis. SPE markets a package of telecommunication products and services. SPC was formed in 1999 to provide telecommunications services using fiber optic cable technology in both northern and southern Nevada. Also, SPC and a subsidiary of Montana Power Company are in a partnership that is constructing a fiber optic line between Salt Lake City, Utah and Sacramento, CA.

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

100

of contingent assets and liabilities at the date of the financial statements and the reported amounts of certain revenues and expenses during the reporting period. Actual results could differ from these estimates.

Certain reclassifications of prior year information have been made for comparative purposes but have not affected previously reported net income or common shareholders' equity.

Deferral of Energy Costs

Nevada and California statutes permit regulated utilities to, from time-to-time, adopt deferred energy accounting procedures. The intent of these procedures is to ease the effect of fluctuations in the cost of purchased gas, fuel and purchased power. Under deferred energy accounting, to the extent actual fuel and purchased power costs exceed fuel and purchased power costs recoverable through current rates, that excess is not recorded as a current expense on the income statement but rather is deferred and recorded as an asset on the balance sheet. Conversely, a liability is recorded to the extent fuel and purchased power costs recoverable through current rates exceed actual fuel and purchased power costs. These excess amounts are reflected in adjustments to rates and recorded as revenue or expense in future time periods. AB 369 requires the Utilities to use deferred energy accounting for their respective electric operations beginning on March 1, 2001, and to file applications to clear their respective deferred energy account balances at least every 12 months. See Note 3 for additional information on the deferred energy accounting provisions of AB 369.

NPC utilized deferred energy accounting procedures in 1999, and part of 2000. NPC ceased utilizing deferred energy accounting effective August 1, 2000, and resumed those procedures on March 1, 2001. During 1999, SPPC did not employ deferred energy accounting procedures, but resumed those procedures for natural gas operations as of January 1, 2000, and for its electric operations on March 1, 2001.

Utility Plant

In addition to direct labor and material costs, the Utilities also charge the following to the cost of constructing utility plant: the cost of time spent by administrative employees in planning and directing construction work; property taxes; employee benefits (including such costs as pensions, postretirement and postemployment benefits, vacations and payroll taxes); and an allowance for funds used during construction (AFUDC).

The original cost of plant retired or otherwise disposed of and the cost of removal less salvage is generally charged to the accumulated provision for depreciation. The cost of current repairs and minor replacements is charged to operating expenses when incurred. The cost of renewals and betterments is capitalized.

Allowance For Funds Used During Construction and Capitalized Interest

As part of the cost of constructing utility plant, the Utilities capitalize AFUDC. AFUDC represents the cost of borrowed funds and, where appropriate, the cost of equity funds used for construction purposes in accordance with rules prescribed by the FERC and the Public Utility Commission of Nevada ("PUCN"). AFUDC is capitalized in the same manner as construction labor and material costs, with an offsetting credit to "other income" for the portion representing the cost of equity funds and as a reduction of interest charges for the portion representing borrowed funds. Recognition of this item as a cost of utility plant is in accordance with established regulatory ratemaking practices. Such practices permit the utility to earn a fair return on, and recover in rates charged for utility services, all capital costs. This is accomplished by including such costs in the rate base and in the provision for depreciation. NPC's AFUDC rates used during 2001, 2000, and 1999 were 8.32%, 8.34%, and 8.55%, respectively. SPPC's AFUDC rates used during 2001, 2000, and 1999 were 7.94%,

101

7.17%, and 6.09%, respectively. As specified by the PUCN, certain projects were assigned a lower AFUDC rate due to specific low-interest-rate financings directly associated with those projects.

Depreciation

Depreciation is calculated using the straight-line composite method over the estimated remaining service lives of the related properties. NPC's depreciation provision for 2001, 2000, and 1999, as authorized by the PUCN and stated as a percentage of the original cost of depreciable property, was approximately 2.9%. SPPC's depreciation provision for 2001, 2000, and 1999, as authorized by the PUCN and stated as a percentage of the original cost of depreciable property, was approximately 3.21%, 3.21%, and 3.14%, respectively.

Cash and Cash Equivalents

Cash is comprised of cash on hand and working funds. Cash equivalents consist of high quality investments in money market funds.

Regulatory Accounting and Other Regulatory Assets

The Utilities' rates are currently subject to the approval of the PUCN and are designed to recover the cost of providing generation, transmission and distribution services. As a result, the Utilities qualify for the application of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation", issued by the Financial Accounting Standards Board (FASB). This statement recognizes that the rate actions of a regulator can provide reasonable assurance of the existence of an asset and requires the capitalization of incurred costs that would otherwise be charged to expense where it is probable that future revenue will be provided to recover these costs. SFAS No. 71 prescribes the method to be used to record the financial transactions of a regulated entity. The criteria for applying SFAS No. 71 include the following: (i) rates are set by an independent third party regulator, (ii) approved rates are intended to recover the specific costs of the regulated products or services, and (iii) rates that are set at levels that will recover costs can be charged to and collected from customers. SFAS No. 101, "Regulated Enterprises-Accounting for the Discontinuation of Application of FASB Statement No. 71", requires that an enterprise whose operations cease to meet the qualifying criteria of SFAS No. 71 discontinue the application of that statement by eliminating the effects of any actions of regulators that had been previously recognized.

In conformity with SFAS No. 71, the accounting for the Utilities conforms to generally accepted accounting principles as applied to regulated public utilities and as prescribed by the agencies and commissions of the jurisdictions in which they operate. In accordance with these principles, certain costs that would otherwise be charged to expense or capitalized as plant costs are deferred as regulatory assets based on expected recovery from customers in future rates. Management's expected recovery of deferred costs is based upon specific ratemaking decisions or precedent for each item. The following other regulatory assets were included in the consolidated balance sheets of SPR as of December 31 (dollars in thousands):

Currently, the electric utility industry is predominantly regulated on a basis designed to recover the cost of providing electric power to its retail and wholesale customers. If cost-based regulation were to be discontinued in the industry for any reason, including competitive pressure on the cost-based prices of electricity, profits could be reduced, and utilities might be required to reduce their asset balances to reflect a market basis less than cost. Discontinuance of cost-based regulation would also require affected utilities to write off their associated regulatory assets. Management cannot predict the potential impact, if any, of these competitive forces on the Utilities' future financial position and results of operations.

Management periodically assesses whether the requirements for application of SFAS 71 are satisfied. The provisions of AB 369, signed into law in April 2001, include the repeal of all statutes authorizing retail competition in Nevada's electric utility industry. Accordingly, the Utilities continue to apply regulatory accounting to the generation, transmission and distribution portions of their businesses.

Federal Income Taxes and Investment Tax Credits

SPR and its subsidiaries file a consolidated federal income tax return. Current income taxes are allocated based on SPR's and each subsidiary's respective taxable income or loss and investment tax credits as if each subsidiary filed a separate return. Deferred taxes are provided on temporary differences at the statutory income tax rate in effect as of the most recent balance sheet date.

SPR accounts for income taxes in accordance with SFAS No. 109, "Accounting for Income Taxes." SFAS No. 109 requires recognition of deferred tax liabilities and assets for the future tax consequences of events that have been included in the consolidated financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.

For regulatory purposes, the Utilities are authorized to provide for deferred taxes on the difference between straight-line and accelerated tax depreciation on post-1969 utility plant expansion property, deferred energy, and certain other differences between financial reporting and taxable income, including those added by the Tax Reform Act of 1986 (TRA). In 1981, the Utilities began providing for deferred taxes on the benefits of using the Accelerated Cost Recovery System for all post-1980 property. In 1987, the TRA required the Utilities to begin providing deferred taxes on the benefits derived from using the Modified Accelerated Cost Recovery System.

Investment tax credits are no longer available to the Utilities. The deferred investment tax credits are being amortized over the estimated service lives of the related properties.

103

Revenues

Operating revenues include billed and unbilled utility revenues. The accrual for unbilled revenues represents amounts owed to the Utilities for service provided to customers for which the customers have not yet been billed. These unbilled amounts are also included in accounts receivable.

Recent Pronouncements

Financial Accounting Standards Board

In June 2001, the FASB issued three new pronouncements, SFAS No. 141, "Business Combinations," SFAS No. 142, "Goodwill and Other Intangible Assets," and SFAS No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001. SFAS No. 142, adopted January 1, 2002, changes the accounting for goodwill from an amortization method to one requiring at least an annual review for impairment. Due to the regulatory treatment anticipated for most of SPR's goodwill, Management does not expect SFAS No. 142 to have a material effect on the financial position or results of operations of SPR, NPC, and SPPC. SFAS No. 143, effective for fiscal years beginning after June 15, 2002, requires an entity to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Management does not expect the adoption of SFAS No. 143 to have a material effect on the financial position or results of operations of SPR, NPC, and SPPC.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This standard provides guidance on the impairment of long-lived assets and for long-lived assets to be disposed of. The standard supersedes the current authoritative literature on impairments as well as disposal of a segment of a business and was adopted January 1, 2002.

Note 1A. FINANCIAL STATEMENTS OF NEVADA POWER COMPANY

As described in Note 2 that follows, NPC was deemed to be the acquirer of SPR for accounting purposes as reflected in the SPR Consolidated Financial Statements. However, after the merger with SPR and as a result of the structure of the transactions, NPC is a separate legal entity, which is a wholly owned subsidiary of SPR. As a legal matter, NPC does not own any equity interest in SPR. The audited NPC Financial Statements accommodate the presentation of financial information of NPC on a stand-alone basis by summarizing all non-NPC financial information into a few items on each of the Financial Statements. These summarized items are repeated below (in 000's):

Non-NPC financial items on the NPC Financial Statements

NOTE 2. SIERRA PACIFIC RESOURCES AND NEVADA POWER MERGER

On July 28, 1999, the merger between SPR and NPC was consummated. The merger was accounted for as a reverse purchase under generally accepted accounting principles, with NPC considered the acquiring entity even though SPR is the surviving legal entity. In addition, for accounting purposes the merger was deemed to have occurred on August 1, 1999. As a result of this reverse purchase accounting treatment: (i) the historical financial statements of SPR for periods prior to the date of the merger are no longer the financial statements of SPR, and therefore, are no longer presented; (ii) the historical financial statements of SPR for periods prior to the date of the merger are those of NPC; and (iii) based on a merger date of August 1, 1999, the Consolidated Statements of Income for the twelve months ended December 31, 1999, include five months (August through

105

December 1999) of operating activity for SPR and its subsidiaries other than NPC. The same statements include the operating results of NPC for the entire periods presented

Through December 31, 2001, SPR incurred a total of $60.2 million in capitalized costs since merger work began. The capitalized merger amounts consist of $38.4 million of transaction and transition costs and $21.8 million of employee separation costs.

Employee severance, relocation, and related costs for SPR were $17.3 million, of which $.4 million remains unpaid as of December 31, 2001. Other costs incurred in connection with employee separations included pension and postretirement benefits net of plan curtailment gains of $4.5 million.

In accordance with the terms of the merger, each outstanding share of SPR's common stock was converted into the right to receive either $37.55 in cash or 1.44 shares of newly issued SPR common stock. Each outstanding share of NPC common stock was converted to the right to receive either $26.00 in cash or 1.00 share of newly issued SPR common stock. 4,037,000 shares of SPR and 11,716,611 shares of NPC common stock were exchanged for $151.6 million and $304.6 million, respectively. The remaining shares of each company were converted to newly issued shares of SPR common stock. SPR stockholders and NPC stockholders received 38,866,054 and 39,548,506 shares, respectively, of newly issued SPR common stock, resulting in 78,414,560 outstanding shares of SPR on August 1, 1999.

The total consideration paid to SPR common stockholders was equal to cash of $151.6 million and 38,866,054 shares of newly issued SPR common stock at a price of $24.18 per share based on the average closing price of NPC common stock between April 22, 1998 and May 6, 1998. The eleven-day average price of NPC common stock used in determining the total stock consideration represents the market price over a reasonable period of time before and after the transaction was announced on April 29, 1998. Goodwill of $331.2 million was recorded in connection with the merger. The order of the PUCN approving the merger allowed SPR to defer merger costs (including goodwill) allocable to the regulated Utilities for a three-year period. Accordingly, goodwill amortization through December 31, 2001, associated with the regulated Utilities has been reclassified to a regulatory asset.

On October 1, 2001, and November 30, 2001, NPC and SPPC, respectively, filed applications with the PUCN for general rate increases that included, among other items, a request to recover deferred merger costs, including goodwill. The Utilities have proposed to recover merger transition and transaction costs over ten years and goodwill over forty years. Decisions on the NPC and SPPC cases are expected no later than April 1, 2002, and June 1, 2002, respectively. See Note 3 "Regulatory Actions" for additional information about these rate cases.

NOTE 3. REGULATORY ACTIONS

Nevada Matters (NPC and SPPC)

The Utilities are subject to the jurisdiction of the PUCN and, in the case of SPPC, the California Public Utility Commission (CPUC) with respect to rates, standards of service, siting of and necessity for, generation and certain transmission facilities, accounting, issuance of securities and other matters with respect to electric distribution and transmission operations. NPC and SPPC submit integrated resource plans to the PUCN for approval.

Under federal law, the Utilities are subject to certain jurisdictional regulation, primarily by the FERC. The FERC has jurisdiction under the Federal Power Act with respect to rates, service, interconnection, accounting, and other matters in connection with the Utilities' sale of electricity for resale and interstate

106

transmission. The FERC also has jurisdiction over the natural gas pipeline companies from which the Utilities take service.

As a result of regulation, many of the fundamental business decisions of the Utilities, as well as the rate of return they are permitted to earn on their utility assets, are subject to the approval of governmental agencies.

Nevada Legislation

On April 18, 2001, the Governor of Nevada signed into law AB 369. The provisions of AB 369 include a moratorium on the sale of generation assets by electric utilities, the repeal of electric industry restructuring, and a reinstatement of deferred energy accounting for fuel and purchased power costs incurred by electric utilities. Set forth below is a summary of key provisions of AB 369.

Generation Divestiture Moratorium

AB 369 prohibits all divestiture of generation assets by electric utilities until July 2003. After January 1, 2003, NPC or SPPC may seek PUCN permission to sell one or more generation assets with the sale to be effective on or after July 1, 2003. The PUCN may approve the request to divest only if it finds the transaction to be in the public interest. The PUCN may base its approval of the request upon such terms, conditions, or modifications as it deems appropriate.

AB 369 directs the PUCN to take all steps necessary to obtain federal approval for the prohibition on divestiture and to vacate any of its own orders that had previously approved generation divestiture transactions.

Deferred Energy Accounting

AB 369 required the Utilities to use deferred energy accounting for their respective electric operations beginning on March 1, 2001. The intent of deferred energy accounting is to ease the effect of fluctuations in the cost of purchased power and fuel. Under deferred energy accounting, to the extent actual fuel and purchased power costs exceed fuel and purchased power costs recoverable through current rates, that excess is not recorded as a current expense on the income statement but rather is deferred and recorded as an asset on the balance sheet. Conversely, a liability is recorded to the extent fuel and purchased power costs recoverable through current rates exceed actual fuel and purchased power costs. These excess amounts are reflected in adjustments to rates and recorded as revenue or expense in future time periods, subject to PUCN review. AB 369 provides that the PUCN may not allow the recovery of any costs for purchased fuel or purchased power "that were the result of any practice or transaction that was undertaken, managed or performed imprudently by the electric utility." In reference to deferred energy accounting, AB 369 specifies that fuel and purchased power costs include all costs incurred to purchase fuel, to purchase capacity, and to purchase energy. The Utilities also record, and are eligible to recover, a carrying charge on such deferred balances.

AB 369 requires that each Utility file an application to clear its deferred energy account balances after the end of each 12-month period, but allows the balances from each 12-month period to be recovered over an adjustment period of up to three years in order to reduce the volatility of rate changes. In addition, after the initial deferred energy case, each utility is allowed to file an application to clear its deferred energy account balances after the end of a six-month period if the proposed net increase or decrease in fuel and purchased power revenues for the six-month period is more than 5%. If a utility using deferred energy accounting realizes a rate of return greater than the rate authorized by the PUCN, the portion that exceeds the authorized rate of return will be transferred to the next deferred energy adjustment period.

Before an electric utility may clear its deferred accounts, AB 369 requires the PUCN to determine whether the costs for purchased fuel and purchased power that the electric utility recorded in its deferred

107

accounts are recoverable and whether the revenues that the electric utility collected from customers in Nevada for purchased fuel and purchased power are properly recorded and credited in its deferred accounts. AB 369 prohibits the PUCN from allowing an electric utility to recover any costs for purchased fuel and purchased power that were the result of any practice or transaction that was undertaken, managed or performed imprudently by the electric utility. To the extent that the PUCN finds that any amount included in either Utility's deferred account was imprudently incurred, the PUCN will not permit that amount to be recovered through higher rates, and an equivalent amount of the Utility's deferred energy costs asset will be required to be written off. Such a write-off could cause a substantial loss to be incurred by the Utility, could cause its securities to be downgraded by the rating agencies, and could make it significantly more difficult to finance the operations of the Utility and to buy fuel and purchased power from third parties.

In addition, as discussed under "Required Filings" below, the PUCN must determine whether the rates that went into effect on March 1, 2001, pursuant to the CEP as filed by the Utilities with the PUCN on January 29, 2001, are just and reasonable and reflect prudent business practices.

Transition of Rates to Deferred Energy Accounting

All rates in effect on April 1, 2001, including the cumulative increases under the Global Settlement and the CEP Riders, remain in effect until the PUCN issues final orders on future general and initial deferred energy rate applications. (See "Required Filings," below). No further applications can be made for the Fuel and Purchased Power (F&PP) riders that were part of the July 2000 Global Settlement described in SPR's Annual Report on Form 10-K for the year ended December 31, 2000.

The Utilities are not permitted to recover any shortfall incurred before March 1, 2001, resulting from the difference between actual fuel and purchased power costs and the rates permitted by the Global Settlement. Although the F&PP riders were in effect during this period, the riders were based on trailing 12-month average costs and were subject to caps and, therefore, did not allow the Utilities full recovery for fuel and purchased power costs due to the rapid rise in energy prices.

AB 369 prohibits the PUCN from taking any further action on the CEP, and provides that, except for the CEP Rider rate increases put in effect on April 1, 2001, the CEP will be deemed to have been withdrawn by the Utilities. Additionally, approximately $20 million of revenue collected by the Utilities based on the CEP before April 1, 2001 was credited to the deferred energy accounts, which caused the accounts to start in an over-collected position.

Required Filings

The Utilities have both filed a general rate application and a deferred energy application on the dates listed below:

                                        General Rate Case              Deferred Energy Filing
                                        -----------------              ----------------------
                                  File Date      Effective Date     File Date      Effective Date
Nevada Power Company             Oct. 1, 2001     April 1, 2002    Dec. 1, 2001     April 1, 2002
Sierra Pacific Power Company     Dec. 1, 2001     June 1, 2002     Feb. 1, 2002     June 1, 2002

In connection with clearing the Utilities' deferred energy accounts, the PUCN must investigate and determine whether the Utilities' rates that went into effect on March 1, 2001, pursuant to the CEP, are just and reasonable and reflect prudent business practices. The rates in effect on April 1, 2001, remain in effect until the PUCN issues final orders on the general and initial deferred energy rate applications referred to above. The PUCN is prohibited from adjusting rates during this time period unless an adjustment is absolutely necessary to avoid a finding that the rates are confiscatory and, therefore, in violation of the United States or Nevada

108

Constitutions. If adjustments are necessary, they may only be made to the extent necessary to avoid an unconstitutional result.

After the initial general rate applications described above, each Utility will be required to file future general rate applications at least every 24 months.

Restrictions on Mergers and Acquisitions

AB 369 imposes certain restrictions on mergers and acquisitions involving Nevada electric utilities. In particular, the PUCN may not approve a merger or acquisition involving an electric utility unless the utility complies with the generation divestiture provisions of AB 369.

In addition, AB 369 includes provisions that would have significantly affected the required regulatory approvals for the proposed acquisition of PGE from Enron. On April 26, 2001, Enron and SPR terminated, by mutual agreement, the proposed purchase and sale of PGE.

AB 369 also provides that if an electric utility holding company acquires an interest in an out-of-state public utility prior to July 1, 2003, each electric utility in which the holding company holds a controlling interest shall not be entitled to the benefit of deferred energy accounting. Thus, in the event that SPR acquires an out-of-state public utility, NPC and SPPC would lose the ability to utilize deferred energy accounting.

Repeal of Electric Industry Restructuring

AB 369 repeals all statutes authorizing retail competition in Nevada's electric utility industry and voids any license issued to an alternative seller in connection with retail electric competition.

Other Legislation

SB 372, which increased renewable energy portfolio requirements, was enacted in the 2001 Nevada legislative session. Renewable resources include biomass, wind, solar, and geothermal projects. In 2003, the Utilities will be required to purchase five percent of their energy from renewable resources. These requirements increase to 15% by 2013. Prior law capped renewable energy requirements at one percent. Currently, SPPC obtains approximately nine percent of its energy from renewable resources, while NPC obtains less than one percent from renewables. SB 372 requires the PUCN to establish standards for renewable energy contracts, including prices and other terms and conditions. If sufficient renewable energy contracts that meet PUCN standards are not available, the Utilities will not be required to meet the portfolio requirements. All renewable energy contracts meeting PUCN standards will be recoverable in the deferred energy accounts.

The 2001 Nevada legislature passed another key piece of legislation for the Nevada energy industry, AB 661. AB 661 allows commercial and governmental customers with an average demand greater than 1 MW to select new energy suppliers. The Utilities would continue to provide transmission, distribution, metering and billing services to such customers. AB 661 requires customers wishing to choose a new supplier to receive the approval of the PUCN and meet public interest standards. In particular, departing customers must secure new energy resources that are not under contract to the Utilities, remaining customers or the utility cannot be negatively impacted by the departure, and the departing customers must pay any deferred energy balances. The PUCN has adopted regulations prescribing the criteria that will be used to determine if there will be negative impacts to remaining customers or the utility. Certain limits are placed upon the departure of NPC customers until 2003; most significantly, the amount of load departing is limited to approximately 1100 MW in peak conditions. AB 661 permits customers to file applications with the PUCN beginning in the fourth quarter of 2001. Customers must provide 180-day notice to the Utilities and could begin to receive service from new

109

suppliers by mid-2002. On January 10, 2002, an approximately 130 MW SPPC customer submitted an application to the PUCN under AB 661. The customer, SPPC, and PUCN staff are negotiating a stipulation regarding settlement of the terms and conditions under which this customer will be permitted to procure energy from an alternative source other than SPPC. The terms and conditions of the stipulation are expected to comply with the provisions of AB 661 in that SPPC and its remaining customers will not be negatively impacted by the customer's departure. A hearing on the stipulation has been set for March 20, 2002.

AB 661 also contains new electric and gas energy surcharges for low-income assistance and weatherization programs. These surcharges are recoverable directly from customers as separate line items on their bills with the Utilities remitting collected surcharges to the PUCN. Various state agencies will administer the disposition of the funds.

Nevada Power Company General Rate Case (NPC)

On October 1, 2001, NPC filed an application with the PUCN seeking an electric general rate increase. This application was mandated by AB 369, which was enacted by the Nevada legislature in April 2001. On December 21, 2001, NPC filed a Certification to its general rate filing updating costs and revenues pursuant to Nevada regulations. In the certification filing, NPC requested an increase in its general rates charged to all classes of electric customers designed to produce an increase in annual electric revenues of $22.7 million, which is an overall 1.7% rate increase. The application also seeks a return on common equity ("ROE") for Nevada Power's total electric operations of 12.25% (a reduction from NPC's last-authorized ROE for bundled electric operations of 12.50%) and an overall rate of return ("ROR") of 9.30% (a reduction from NPC's last-authorized ROR for bundled electric operations of 10.02%). Public hearings on NPC's general rate case began on February 4, 2002. Various parties have intervened in NPC's general rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, MGM/Mirage, and the Nevada Coalition Of Commercial Energy Consumers. The reduction of NPC's revenue requirements proposed by the intervenors ranges from $50 million to $107 million.

Nevada Power Company Deferred Energy Case (NPC)

On November 30, 2001, NPC filed an application with the PUCN seeking to clear deferred balances for purchased fuel and power costs accumulated between March 1, 2001 through September 30, 2001. This application was mandated by AB 369, which was enacted by the Nevada Legislature in April 2001. The application seeks to establish a Deferred Energy Accounting Adjustment ("DEAA") rate to clear accumulated purchased fuel and power costs of $922 million and spread the cost recovery over a not more than three-year period. It also seeks to recalculate the Base Tariff Energy Rate to reflect anticipated ongoing purchased fuel and power costs. The total rate increase resulting from the DEAA would amount to 21%. NPC has proposed an alternate plan in which full recovery of the deferred balance would be amortized over a period greater than three years, but not to exceed six years. Public hearings began March 4, 2002. Various parties have intervened in NPC's deferred energy rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, MGM/Mirage, the Southern Nevada Water Authority, the Nevada Energy Buyers Group, and the Nevada Coalition Of Commercial Energy Consumers. The disallowance of NPC's deferred energy balance that is proposed by the intervenors ranges from $85 million to $980 million.

Sierra Pacific Power Company General Rate Case (SPPC)

On November 30, 2001, SPPC filed an application with the PUCN seeking an electric general rate increase. This application was mandated by AB 369, which was enacted by the Nevada Legislature in April 2001. On February 28, 2002, SPPC filed a certification to its general rate filing, updating costs and revenues pursuant to Nevada regulations. In the certification filing, SPPC requested an increase in its general rates charged to all classes of electric customers, which were designed to produce an increase in annual electric

110

revenues of $15.9 million representing an overall 2.4% rate increase. The application also seeks an ROE for SPPC's total electric operations of 12.25% (an increase from SPPC's last authorized ROE for bundled electric operations of 12.0%) and an overall ROR of 9.42% (a reduction from SPPC's last authorized ROR for bundled electric operations of 10%). Public hearings for SPPC's general rate case are scheduled to begin on April 8, 2002. Various parties have intervened in SPPC's general rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, and Barrick Goldstrike Mines, among others. Intervenor testimony will not be filed until March 22, 2002.

Sierra Pacific Power Company Deferred Energy Case (SPPC)

On February 1, 2002, SPPC filed an application with the PUCN seeking to clear deferred balances for purchased fuel and power costs accumulated between March 1, 2001 and November 30, 2001. This application was mandated by AB 369. The application seeks to establish a DEAA rate to clear accumulated purchased fuel and power costs of $205 million and spread the cost recovery over a not more than three-year period. It also seeks to recalculate the Base Tariff Energy Rate to reflect anticipated ongoing purchased fuel and power costs. The total rate increase resulting from the DEAA would amount to 9.8%. SPPC has proposed an alternate plan in which full recovery of the deferred balance would be amortized over a period greater than three years, but not to exceed six years. Public hearings are scheduled to begin in April 2002. Various parties have intervened in SPPC's deferred energy rate case including the Staff of the PUCN, the Bureau of Consumer Protection from the Nevada Attorney General's office, and Barrick Goldstrike Mines, among others. Intervenor testimony will not be filed until April 22, 2002.

Finance Authority (NPC, SPPC)

On September 20, 2001, the PUCN approved the June 19, 2001 applications by the Utilities for authority to issue long or short-term debt on either a secured or unsecured basis in an aggregate amount not to exceed $200 million for NPC and $100 million for SPPC through the end of 2002. NPC has issued all of its $200 million of authorized debt. SPPC has not issued any debt under this authority and has the full amount of the $100 million of authorized debt available for future issuances. On September 20, 2001, the PUCN also approved the Utilities' June 19, 2001 applications to amend an order issued by the PUCN allowing each of the Utilities to issue unsecured short-term promissory notes in an amount not to exceed $250 million through the period ending December 31, 2001. In the applications, the Utilities requested that the PUCN amend its previous order to provide the Utilities with the flexibility to issue secured promissory notes in addition to, or in lieu of, the authorized unsecured promissory notes.

On October 1, 2001, NPC and SPPC each filed an application with the PUCN requesting authority to issue secured or unsecured promissory notes in aggregate amounts not to exceed $250 million through December 31, 2004. On October 9, 2001, the Utilities filed amended applications reducing the time period to December 31, 2003. On November 29, 2001, the PUCN issued a compliance order approving the requests. Currently, NPC has $50 million and SPPC has $100 million of short-term debt authority remaining from these PUCN authorizations.

Natural Gas Rate Increase (SPPC)

On June 29, 2001, SPPC filed with the PUCN a Purchase Gas Adjustment (PGA) seeking recovery of $41.4 million in accumulated, unrecovered purchased gas expenses, and an increase in the going-forward rate to $.71 per therm. Public hearings were held on October 22 and 23, 2001. On November 5, 2001, the PUCN granted SPPC's application and approved recovery of the entire $41.4 million accumulated deferred balance over a three-year period and an increase in the going-forward rate to $.6648 per therm. Any over or under-recovery of future energy costs will be the subject of a future PGA application. SPPC will file its next PGA on July 1, 2002.

FERC Matters (NPC and SPPC)

Price Mitigation Plan

On June 19, 2001, the FERC adopted a price mitigation plan applicable to spot market wholesale power sales in California and throughout the western United States during the period June 20, 2001 through September 30, 2002. The price mitigation plan establishes a mechanism with which to determine the maximum amount that may be charged for power sold during this period. The intent of the mitigation plan is to simulate the price that might be charged for electricity sold under competitive market conditions. Sellers that do not wish to establish rates on the basis of this price mitigation plan may propose cost-of-service rates covering all of their generating units in the WSCC for the duration of the mitigation plan. Although the Utilities are not able to predict at this time the long-term effect that the FERC price mitigation and other market developments plan may have on their results of operations, management believes that, under certain market conditions, the FERC plan adversely affects the availability of spot market power to the Utilities and reduces the price at which the Utilities can sell power on the wholesale market. Another potential result from these price mitigation measures could be the delay and/or cancellation of proposed power plants throughout the western United States. If these results occur, the long-term supply of energy could be reduced. Numerous parties, including NPC and several northwest utilities, appealed the June 19 and July 25, 2001 orders from the FERC to the District of Columbia Court of Appeals on the basis that the price caps are unfair to electric customers who reside outside of California. In a report to Congress on January 31, 2002, the FERC said the price mitigation plan had little if any influence on prices at which Western utilities were able to resell power. SPR is not persuaded by the FERC's report and continues to believe that the FERC's price caps have negatively impacted electric customers outside California. The parties to the appeal await action by the Court.

Wholesale Sales Tariffs

On March 13, 2001, the Utilities each filed an application for an order approving market-based rates. The market-based authority would apply to sales of electric energy and capacity outside of the Utilities' control areas. On May 11, 2001, SPPC and NPC received approval for market-based rates subject to a compliance order. SPPC's and NPC's compliance filing was accepted on August 10, 2001.

California Matters (SPPC)

Rate Stabilization Plan

SPPC serves approximately 44,500 customers in California. On June 29, 2001, SPPC filed with the CPUC a Rate Stabilization Plan, which includes two phases. Phase One, which was also filed June 29, 2001, is an emergency electric rate increase of $10.2 million annually or 26%. If granted, the typical residential monthly electric bill for a customer using 650 kilowatt-hours would increase from approximately $47.12 to $60.12. On August 14, 2001, a pre-hearing conference was held, and a procedural order was established. On September 27,2001, the Administrative Law Judge issued an order stating that no interim or emergency relief could be granted until the end of the "rate freeze" period mandated by the California restructuring law for recovery of stranded costs. In accordance with the judge's request, on October 26, 2001, SPPC filed an amendment to its application declaring the rate freeze period to be over.

Phase Two, which is scheduled to be filed with the CPUC in April 2002, will be a general rate case to recover costs for expenses other than fuel and purchased power. SPPC will also ask the CPUC to reinstate the Energy Cost Adjustment Clause, which would allow SPPC to file for periodic rate adjustments to reflect its actual costs for fuel and purchased power. Phase Two will also include a proposal pertaining to the termination of the 10% rate reduction mandated by AB 1890. On December 5 and 11, 2001 hearings on Phase One were held and on January 11, 2002, opening briefs were filed. Reply briefs were filed on January 25, 2002. A proposed draft decision is expected by the end of March 2002. SPPC will file Phase Two on April 1, 2002.

SPPC, through its wholly owned subsidiaries, Pinon Pine Corp., Pinon Pine Investment Co., and GPSF-B, owns Pinon Pine Company, L.L.C. (the "LLC"). The LLC was formed to take advantage of federal income tax credits associated with the alternative fuel (syngas) produced by the coal gasifier available under ss. 29 of the Internal Revenue Code. The entire project, which includes an LLC-owned gasifier and an SPPC-owned power island and post-gasification facility to partially cool and clean the syngas, is referred to collectively as the Pinon Pine Power Project ("Pinon Pine"). Construction of Pinon Pine was completed in June 1998.

Pinon Pine is a project co-funded by the Department of Energy (DOE) under an agreement between SPPC and DOE that expired December 31, 2000. Through December 31, 2001, the DOE funded $167 million for construction, operation, and maintenance of the project. Included in the Consolidated Balance Sheets of SPR and SPPC is the net book value of the gasifier and related assets, which is approximately $105 million as of December 31, 2001, of which $50 million is included in Utility Plant, and $55 million is included in Investments in subsidiaries and other property.

114

To date, SPPC has not been successful in obtaining sustained operation of the gasifier. SPPC has retained an independent engineering consulting firm, to complete a comprehensive study of the Pinon Pine gasification plant by mid-2002. The study will evaluate the potential modifications required to make the facility operational and reliable using several technology scenarios. The evaluation of each scenario will include an estimate of the additional capital expenditures necessary for reliable operation of the facility, and the risks associated with that technology.

Although not anticipated, if analysis of the study by SPPC's management indicates there is no economically feasible use of the Pinon Pine assets, SPPC intends to pursue recovery of Pinon Pine, net of salvage, as a regulatory asset. The request for recovery would be based, in part, on the PUCN's approval of Pinon Pine in an earlier resource plan. In that event, if SPPC is unsuccessful in obtaining recovery, there could be a material adverse effect on SPPC's and SPR's financial condition and results of operations.

NOTE 6. JOINTLY OWNED FACILITIES

The above amounts for Navajo and Mohave include NPC's share of transmission systems and general plant equipment and, in the case of Navajo, NPC's share of the jointly owned railroad which delivers coal to the plant. Each participant provides its own financing for all of these jointly owned facilities. NPC's share of operating expenses for these facilities is included in the corresponding operating expenses in the Consolidated Statements of Income.

The Mohave Generating Station is jointly owned by Southern California Edison (56%), Los Angeles Department of Water and Power (20%), NPC (14%) and Salt River Project (10%). According to the terms of the operating agreement, if any of the participants default on their contractual obligations for a period of six (6) months, thereafter the output of the station is reduced by the defaulting participant's percentage of ownership. The non-defaulting participants would then assume the station's reduced variable costs and ongoing fixed operating costs in accordance with their respective ownership percentages. The non-defaulting participants would submit the dispute or default to a board of arbitrators, which would determine what remedies are necessary to resolve the dispute or remedy the default. At December 31, 2001, none of the participants had defaulted on their contractual obligations.

SPPC and Idaho Power Company each own an undivided 50% interest in the Valmy generating station, with each company being responsible for financing its share of capital and operating costs. SPPC is the operator of the plant for both parties. SPPC's share of direct operation and maintenance expenses for Valmy is included in the accompanying Consolidated Statements of Income.

NOTE 7. COMMON STOCK AND OTHER PAID-IN CAPITAL

As of December 31, 2001, 3,508,039 shares of common stock were reserved for issuance under the Common Stock Investment Plan (CSIP), Employees' Stock Purchase Plan (ESPP), Non-Employee Director Stock Plan and Executive Long-Term Incentive Plan (ELTIP). The ELTIP for key management employees allows for the issuance of SPR's common shares to key employees through December 31, 2003. This Plan permits the following types of grants, separately or in combination:
nonqualified and qualified stock options; stock appreciation rights; restricted stock; performance units; performance shares and bonus stock. SPR also provides an ESPP to all of its employees meeting minimum service requirements. Employees can choose twice each year to have up to 15% of their base earnings withheld to purchase SPR common stock. The purchase price of the stock is 90% of the market value on the offering date or 100% of the market price on the execution date, if less. The Non-employee Director Stock Plan provides that a portion of SPR's outside directors' annual retainer be paid in SPR common stock. SPR records the costs of these plans in accordance with Accounting Principles Board Opinion Number 25.

As a part of the August 1, 1999, merger, the NPC ELTIP was terminated and existing SPR plans were adopted by the surviving company.

On September 21, 1999, the Board of Directors of SPR (the "SPR Board") declared a dividend distribution of one right (an "SPR Right") for each outstanding share of SPR common stock to shareholders of record at the close of business on October 31, 1999. By issuing the new SPR Rights, the SPR Board extended the benefits and protections afforded to shareholders under the Rights Agreement, dated as of October 31, 1989, which expired on October 31, 1999. Each SPR Right, initially evidenced by and traded with the shares of SPR Common Stock, entitles the registered holder (other than an "Acquiring Person" as defined in the Rights Agreement) to purchase at an exercise price of $75.00, $150.00 worth of common stock at its then-market value, subject to certain conditions and approvals set forth in the Rights Agreement. If, at any time while there is an Acquiring Person, SPR engages in a merger or other business combination transaction or series of related transactions in which the Common Stock is changed or exchanged or 50% or more of its assets or earning power is transferred, each SPR Right (not previously voided by the occurrence of a Flip-in Event, as described in the Rights Agreement) will entitle its holder to purchase, at the SPR Right's then-current Exercise Price, common stock of such Acquiring Person having a calculated value of twice the SPR Right's then-current Exercise Price. The SPR Rights are not exercisable until the Distribution Date and expire on October 31, 2009, unless previously redeemed by SPR. Following an SPR Distribution Date, the SPR Rights will trade separately from the SPR Common Stock and will be evidenced by separate certificates. Until an SPR Right is exercised, the holder thereof will have no rights as a shareholder of SPR, including, without limitation, the right to receive dividends. The purpose of the plan is to help ensure that SPR's shareholders receive fair and equal treatment in the event of any proposed hostile takeover of SPR.

On August 15, 2001, SPR completed a public offering of 23,575,000 shares of its common stock, yielding net proceeds of approximately $340 million, all of which were contributed to NPC as an additional equity investment.

On November 16 and 21, 2001, SPR completed a public offering of 6,900,000 of its Corporate PIES, yielding net proceeds of approximately $345 million. Each Corporate PIES unit consists of a forward stock purchase contract and a senior unsecured note issued by SPR with a face amount of $50. The senior notes are pledged as collateral to secure each holder's obligation to purchase shares of SPR common stock under the stock purchase contract. The senior note may be released from the pledge arrangement if a holder opts to create Treasury PIES by delivering a like principal amount of U.S. Treasury securities to the Securities Intermediary in substitution for the senior notes.

Each stock purchase contract obligates the holder to purchase SPR common stock on or before November 15, 2005, the Purchase Contract Settlement Date. The number of shares each investor is entitled to receive will depend on the average closing price of SPR common stock over a 20-day trading period prior to the settlement. Prior to the Purchase Contract Settlement Date, holders of Corporate PIES have the option to pay $50 per Corporate PIES to settle their purchase contract obligations. If the holders do not elect to make a cash payment, the proceeds from the remarketing of the senior notes will be used to satisfy their purchase contract obligations.

The purchase contracts are forward transactions in SPR common stock. Upon issuance, a liability for the present value of the purchase contract adjustment payments, approximately $13.7 million, was recorded in Other deferred credits, with a corresponding reduction to Other paid-in capital. See further discussion regarding these senior notes and the purchase contract adjustment payments at Note 9 - Long-Term Debt. Upon settlement of a purchase contract, SPR will receive the stated amount of $50 on the purchase contract and will issue the required number of shares of common stock. The stated amount received will be credited to stockholders' equity and allocated between the Common stock and Other paid-in capital accounts.

Prior to the issuance of common stock upon settlement of the purchase contracts, SPR expects that the PIES will be reflected in SPR `s earnings per share calculations using the treasury stock method. Under this method, the number of shares of common stock used in calculating earnings per share is deemed to be increased by the excess, if any, of the number of shares of common stock issuable upon settlement of the purchase contracts over the number of shares that could be purchased by SPR in the market at the average closing price during the relevant period using the proceeds receivable upon settlement. As a result, SPR expects there will be no dilutive effect on its earnings per share except during periods when the average closing price per share of common stock is above the threshold appreciation price.

The changes in common stock and additional paid-in capital for 2001, 2000, and 1999, are as follows (dollars in thousands):

The QUIPS and the common securities represent undivided beneficial ownership interests in the assets of the Trust, a statutory business trust formed under the laws of the state of Delaware. The existence of the Trust is for the sole purpose of issuing the QUIPS and the common securities and using the proceeds thereof to purchase from NPC its 8.2% Junior Subordinated Deferrable Interest Debentures (QUIDS) due March 31, 2037, extendible to March 31, 2046, under certain conditions, in a principal amount of $122.6 million.

NPC's obligations provide a full and unconditional guarantee of the Trust's obligations under the QUIPS. Financial statements of the Trust are consolidated with NPC's. Separate financial statements are not filed because the Trust is wholly owned by NPC and essentially has no independent operations, and NPC's guarantee of the Trust's obligations is full and unconditional.

Preferred Stock

SPPC's Restated Articles of Incorporation, as amended on August 19, 1992, authorize an aggregate total of 11,780,500 shares of preferred stock at any given time.

On November 1, 1999, SPPC paid $23.5 million, par value and premium, to redeem Series A, $2.44 Dividend (4.88%), Series B, $2.36 Dividend (4.72%) and Series C, $3.90 Dividend (7.8%).

On February 15, 2001, SPPC received consents from the holders of a majority of its preferred stock to increase the amount of unsecured indebtedness that SPPC may issue. Under SPPC's Restated Articles of Incorporation, SPPC cannot, without the consent of a majority of the total number of votes which may be cast by the holders of SPPC's preferred stock, issue unsecured debt securities with maturities of greater than 12 months for any purpose (other than refunding outstanding unsecured debt or retiring outstanding shares of preferred stock) if such unsecured indebtedness would exceed 20% of the aggregate of (1) the total principal amount of all bonds and other securities representing secured indebtedness then outstanding and (2) the total capital and surplus of SPPC then stated on its books. As of September 30, 2000, prior to the consent solicitation, SPPC could issue approximately $14 million in additional unsecured debt under this limitation. Pursuant to the consent solicitation, SPPC received the consent of the holders of a majority of its preferred stock to issue up to $400 million in long-term unsecured indebtedness in excess of the present limitation. As of December 31, 2001, SPPC would have been able to issue approximately $634 million of additional unsecured indebtedness. Upon receipt of the required number of consents, SPPC paid a participation premium in the amount of $.50 per share consented to each holder of shares of preferred stock whose valid, unrevoked consent was received prior to the specified return date. The aggregate amount of the participation premium paid was $.9 million. The only series of preferred stock of SPPC currently outstanding is its Class A, Series 1 Preferred Stock, of which 2 million shares are outstanding.

Nevada Power Company

On April 20, 2000, NPC utilized a $100 million capital contribution from SPR to retire $85 million of NPC's First Mortgage Bonds that matured on May 1, 2000, and to reduce outstanding commercial paper balances under NPC's commercial paper program that was established in July 1999.

On June 22, 2000, Clark County, Nevada issued for NPC's benefit $100 million Industrial Development Refunding Revenue Bonds, Series 2000A, due June 1, 2020. The interest rate is currently being determined by a Dutch Auction based on an auction period of seven days.

The method of determining the interest rate on the Series A and Series B Bonds may be converted from time to time in accordance with the related Indenture so that such bonds would, thereafter, bear interest at a daily, weekly, flexible, term or auction rate. Both Series A and Series B Bonds are insured by AMBAC Assurance Corporation ("AMBAC"). On August 3, 2001, NPC issued $115 million of its Series BB and Series

120

On April 27, 2001, Washoe County, Nevada issued for SPPC's benefit $80 million of Water Facilities Refunding Revenue Bonds, Series 2001, due March 1, 2036. The bonds bear interest at a term rate of 5.75% per annum from their date of issuance to April 30, 2003. Beginning May 1, 2003, the method of determining the interest rate on the bonds may be converted from time to time in accordance with the related Indenture so that such bonds would, thereafter, bear interest at a daily, weekly, flexible, term or auction rate. The bonds were issued to refund $80 million of Washoe County variable rate Water Facilities Revenue Bonds (Sierra Pacific Power Company Project) Series 1990 on April 30, 2001. SPPC's obligations in respect of the Series 1990 bonds had been supported by a letter of credit that was terminated in connection with the redemption of those bonds. On June 11, 2001, SPPC completed the sale of its water business assets including the Project financed by the sale of the bonds.

121

On June 12, 2001, $200 million of SPPC's floating rate notes matured and were paid in full. The floating rate notes were issued on June 9, 2000, and the net proceeds of the $200 million issue were used to redeem $100 million of floating rate notes on July 14, and the remaining proceeds were used to reduce the amount of SPPC's commercial paper outstanding under the program established in July 1999.

On December 17, 2001, $17 million of SPPC's MTN Series D matured and were paid in full.

Sierra Pacific Resources

On March 31, 2000, $10 million of SPR's Series E senior notes matured and were paid in full.

On April 20, 2000, SPR issued an aggregate of $300 million floating rate notes, $200 million of which matures on April 20, 2003 and the remaining $100 million of which matures on April 20, 2002. Interest on the notes is payable quarterly. The interest rate on the notes for each interest period is a floating rate, subject to adjustment every three months, equal to the LIBOR for three-month U.S. dollar deposits plus a spread of 0.60% for the notes maturing in 2003, and a spread of 0.65% for the notes maturing in 2002.These notes are not entitled to any sinking fund. The notes due 2002 will be redeemable in whole, without premium, at the option of SPR beginning April 20, 2001, and on each interest payment date thereafter. The net proceeds of the $200 million issue were used to retire an equal amount of commercial paper of SPR issued under the line of credit established in July 1999 that was used as temporary funding for the cash portion of the NPC merger consideration. The net proceeds of the $100 million issue were used to make a capital contribution to NPC. On September 26, 2000, SPR entered into a forward swap relating to its $200 million floating rate notes that will mature on April 20, 2003, effectively locking in a LIBOR rate of 6.655%, which will result in an interest rate of 7.255% on the notes until their maturity. This transaction became effective on October 20, 2000.

On May 9, 2000, SPR issued $300 million of its 8.75% Notes due 2005. Interest on the notes is payable semi-annually. The notes are not subject to any sinking fund and are redeemable in whole or in part at any time upon payment of the principal amount of the notes being redeemed, plus accrued interest and a make-whole premium. The net proceeds from the issuance of these notes were used to retire an equal amount of commercial paper issued by SPR under its commercial paper program that was established in July 1999 and was cancelled in June 2001.

On November 16 and 21, 2001, SPR issued an aggregate of $345 million senior unsecured notes in connection with the public offering of 6,900,000 of its Corporate PIES. Each Corporate PIES unit consists of a forward stock purchase contract and a senior unsecured note issued by SPR with a face amount of $50. The senior notes are pledged as collateral to secure each holder's obligation to purchase shares of SPR common stock under the stock purchase contract. The senior note may be released from the pledge arrangement if a holder opts to create Treasury PIES by delivering a like principal amount of U.S. Treasury securities to the Securities Intermediary in substitution for the senior notes.

Each stock purchase contract obligates the holder to purchase SPR common stock on or before November 15, 2005, the Purchase Contract Settlement Date. The number of shares each investor is entitled to receive will depend on the average closing price of SPR common stock over a 20-day trading period prior to the settlement. See further discussion regarding the forward stock purchase contract at Note 7 Common Stock And Other Paid-In-Capital.

Each holder of Corporate PIES is entitled to receive quarterly payments consisting of purchase contract adjustment payments and interest on the senior unsecured notes. The Corporate PIES have a combined rate of 9.0%, which is comprised of the coupon on the senior note of 7.93% and the stated rate of the purchase contract adjustment payments of 1.07%. Interest on the senior unsecured notes began to accrue on November 16, 2001, and quarterly interest payments will be made each quarter beginning with the first payment, which was made on

February 15, 2002. All senior unsecured notes will be remarketed beginning on August 10, 2005, up to and including November 1, 2005, and, if necessary, on November 9, 2005, unless holders of senior notes that are not part of a Corporate PIES elect not to have their senior notes remarketed. Upon remarketing, the interest rate will be reset and the senior notes will accrue interest at the reset rate after the remarketing settlement date. Prior to the Purchase Contract Settlement Date, holders of Corporate PIES have the option to pay $50 per Corporate PIES to settle their purchase contract obligations. If the holders do not elect to make a cash payment, the proceeds from the remarketing of the senior notes will be used to satisfy their purchase contract obligations. If any senior notes remain outstanding after the Purchase Contract Settlement Date, SPR will pay interest payments on those senior notes until their maturity on November 15, 2007.

Purchase contract adjustment payments will accrue from November 16, 2001. Holders received the first quarterly purchase contract adjustment payments of $0.1323 per unit ($913,000 in aggregate) on February 15, 2002, and will receive payments of $0.1338 per unit ($923,000 in aggregate) for each subsequent quarter. Upon issuance, a liability for the present value of the purchase contract adjustment payments, approximately $13.7 million, was recorded in Other Deferred Credits, with a corresponding reduction to Other Paid-in-Capital.

NPC's balance sheets contain a net regulatory asset of $94.4 million at year-end 2001 and $94 million at year-end 2000. The net regulatory asset consists of future revenue to be received from customers (a regulatory asset) of $113.6 million at year-end 2001 and $114 million at year-end 2000, due to flow-through of the tax benefits of temporary differences. Offset against this amount are future revenues to be refunded to customers (a regulatory liability), consisting of $5.9 million at year-end 2001 and $6.4 million at year-end 2000 due to temporary differences for liberalized depreciation at rates in excess of current tax rates, and $13.3 million at year-end 2001 and $13.6 million at year-end 2000 due to unamortized investment tax credits. The regulatory liability for temporary differences related to liberalized depreciation will continue to be amortized using the average rate assumption method required by the Tax Reform Act of 1986. The regulatory liability for temporary differences caused by the investment tax credit will be amortized ratably in the same fashion as the accumulated deferred investment credit. In addition, certain items of deferred taxes represent positive cash flows to NPC. These items reduce rate base and, therefore, are benefits passed through to customers. However, because NPC had a net operating loss for tax purposes in 2001, some of this benefit could not be utilized (i.e., deferred energy).

SPPC's balance sheets contain a net regulatory asset of $33.1 million at year-end 2001 and $32.6 million at year-end 2000. The net regulatory asset consists of future revenue to be received from customers (a regulatory asset) of $63.4 million at year-end 2001 and $65.5 million at year-end 2000, due to flow-through of the tax benefits of temporary differences. Offset against this amount are future revenues to be refunded to customers (a regulatory liability), consisting of $12.8 million at year-end 2001 and $14.5 million at year-end 2000, due to temporary differences for liberalized depreciation at rates in excess of current tax rates, and $17.5 million at year-end 2001 and $18.4 million at year-end 2000 due to unamortized investment tax credits. The regulatory liability for temporary differences related to liberalized depreciation will continue to be amortized using the average rate assumption method required by the Tax Reform Act of 1986. The regulatory liability for temporary differences caused by the investment tax credit will be amortized ratably in the same fashion as the accumulated deferred investment credit. In addition, certain items of deferred taxes represent positive cash flows to SPPC. These items reduce rate base and, therefore, are benefits passed through to customers. However, because SPPC had a net operating loss for tax purposes in 2001, some of this benefit could not be utilized (i.e., deferred energy).

SPR's balance sheets contain a net regulatory asset of $127.7 million at year-end 2001 and $126.7 million at year-end 2000. The net regulatory asset consists of future revenue to be received from customers (a regulatory asset) of $177.1 million at year-end 2001 and $179.6 million at year-end 2000, due to flow-through of the tax benefits of temporary differences. Offset against these amounts are future revenues to be refunded to customers (a regulatory liability), consisting of $18.7 million at year-end 2001 and $20.9 million at

128

year-end 2000, due to temporary differences for liberalized depreciation at rates in excess of current tax rates, and $30.7 million at year-end 2001 and $32 million at year-end 2000 due to unamortized investment tax credits. The regulatory liability for temporary differences related to liberalized depreciation will continue to be amortized using the average rate assumption method required by the Tax Reform Act of 1986. The regulatory liability for temporary differences caused by the investment tax credit will be amortized ratably in the same fashion as the accumulated deferred investment credit. In addition, certain items of deferred taxes represent positive cash flows to SPR. These items reduce rate base and, therefore, are benefits passed through to customers. However, because SPR had a net operating loss for tax purposes in 2001, some of this benefit could not be utilized (i.e., deferred energy).

The Restated Articles of Incorporation of the Utilities, the indentures relating to the various series of their First Mortgage Bonds, and the bank credit agreements of SPR and the Utilities contain restrictions as to the payment of dividends on their common stock and as to the purchase, redemption or retirement of their capital stock.

NOTE 14. RETIREMENT PLAN AND POST-RETIREMENT BENEFITS

Pension and other postretirement benefit plans: SPR has pension plans covering substantially all employees. Benefits are based on years of service and the employee's highest compensation for a period prior to retirement. SPR also has other postretirement plans which provide medical and life insurance benefits for certain retired employees. The following table provides a reconciliation of benefit obligations, plan assets and the funded status of the plans. This reconciliation is based on a September 30 measurement date and reflects the acquisition of SPPC by NPC during 1999 under purchase accounting:

NOTE 15. STOCK COMPENSATION PLANS

At December 31, 2001, Sierra Pacific Resources had several stock-based compensation plans which are described below. SPR applies Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, in accounting for its stock option plans. Accordingly, no compensation cost has been recognized for nonqualified stock options and the employee stock purchase plan. The total compensation cost (benefit) that has been charged against income for the performance shares, dividend equivalents, restricted stock grants, and the non-employee director stock plans was $0.5 million for 2001, ($0.2 million) for 2000, and $0.2 million for 1999. SPR has adopted the disclosure-only provisions of SFAS No. 123, Accounting for Stock Based Compensation. Had compensation cost for SPR's nonqualified stock options and the employee stock purchase plan been determined based on the fair value at the grant dates for awards under those plans consistent with the provisions of SFAS No. 123, SPR's income applicable to common stock would have been decreased to the pro forma amounts indicated below:

                                                       2001       2000        1999

SPR's executive long-term incentive plan for key management employees, which was approved by shareholders on May 16, 1994, provides for the issuance of up to 750,000 of SPR's common shares to key employees through December 31, 2003. On June 19, 2000, shareholders approved an increase of 1,000,000 shares for the executive long-term incentive plan. The plan permits the following types of grants, separately or in combination: nonqualified and qualified stock options, stock appreciation rights, restricted stock, performance units, performance shares, and bonus stock. During 2001, SPR issued nonqualified stock options, performance shares, and restricted stock under the long-term incentive plan.

Non-Qualified Stock Options

Nonqualified stock options granted during 2001 were issued at an option price not less than market value at the date of the grants: January 1, May 15, May 22, July 19, and November 15. The January 1 grant vests to the participants 33% per year over a 3 year period from the grant date, and the remaining grants vest to the participants 25% per year over a four year period from the grant date. All grants may be exercised for a

134

period not exceeding ten years from the grant date. The options may be exercised using either cash or previously acquired shares, valued at the current market price, or a combination of both.

A summary of the status of SPR's nonqualified stock option plan as of December 31, 2001, 2000, and 1999, and changes during the year is presented below:

 ------------------------------------------------------------------------------------

Each participant was granted dividend equivalents for all 1996 and prior nonqualified option grants. Each dividend equivalent entitles the participant to receive a contingent right to be paid an amount equal to dividends declared on shares originally granted from the date of grant through the exercise date. Dividend equivalents will be forfeited if options expire unexercised.

Performance Shares

In 2001, 2000 and 1999, SPR granted performance shares in the following numbers and initial values:

                      1/1/2001    8/4/2000     1/1/2000    1/1/1999

Shares Granted         135,906       4,798       31,707      28,944
Value per Share       $  14.80      $16.00      $ 26.00     $ 24.22

The actual number of shares earned by each participant is dependent upon SPR achieving certain financial goals over three-year performance periods. However, 66,100 shares included in the number granted on 1/1/2001 have a one-year performance period, from January 1 through December 31, 2001. The value of all performance share grants, if earned, will be equal to the market value of SPR's common shares as of the end of the performance periods. Sierra Pacific Resources, at its sole discretion, may pay earned performance shares in the form of cash or in shares, or a combination thereof. The grant of 66,100 shares on 1/1/2001 will be paid in SPR stock only.

136

Simultaneous with the grant of the performance shares above, each participant was granted dividend equivalents. Each dividend equivalent entitles the participant to receive a contingent right to be paid an amount equal to dividends declared on shares originally granted throughout the performance period. Additionally, in order for dividend equivalents to be paid on the performance shares, certain financial targets must be met. Dividend equivalents will be forfeited if options expire unexercised.

Restricted Stock Shares

In 2001, SPR granted 13,200 restricted stock shares, detailed as follows:

                                            Grant Date

Vesting Schedule for all: 4 years, 25% per year

In 2000, SPR granted 16,000 restricted stock shares at a grant price of $16.00 per share. The grant vests over 4 years with 4,000 shares becoming available in 2002, 4,000 shares in 2003, and 8,000 shares in 2004. No restricted stock grants were issued in 1999. There are no performance criteria associated with the restricted stock grants, and all grants were issued with an entitlement to dividend equivalents.

Employee Stock Purchase Plan

Upon the inception of SPR's employee stock purchase plan, SPR was authorized to issue up to 400,162 shares of common stock to all of its employees with minimum service requirements. On June 19, 2000, shareholders approved an additional 700,000 shares for distribution under the plan. According to the terms of the plan, employees can choose twice each year to have up to 15% of their base earnings withheld to purchase SPR's common stock. The purchase price of the stock is 90% of the market value on the offering commencement date. Employees can withdraw from the plan at any time prior to the exercise date. Under the plan SPR sold 33,830, 46,773 and 21,888 shares to employees in 2001, 2000 and 1999, respectively. Compensation cost has been estimated for the employees' purchase rights on the date of grant using the Black-Scholes option-pricing model with the following assumptions used for 2001, 2000 and 1999:

----------------------------------------------------------------

Non-Employee Director Stock Plan

SPR's non-employee director stock plan provides that a portion of the outside directors' annual retainer be paid in SPR stock. Under the current plan, the annual retainer for non-employee directors is $30,000, and the minimum amount to be paid in SPR stock is $20,000 per director. During 2001, 2000 and 1999, SPR granted the following total shares and related compensation to directors in SPR stock, respectively: 14,573, 16,915 and 4,741 shares, and $210,000, $250,000 and $150,000. SPR did not pay out any phantom stock shares in 2001.

NOTE 16. POSTEMPLOYMENT BENEFITS

During 1999, SPR offered a severance program to non-bargaining-unit employees, which provides for severance pay and medical benefits continuation totaling $14.3 million and $0.8 million respectively. As approved by the PUCN in 1999, this cost is being deferred as a regulatory asset as of December 31, 2001. The order approving the merger by the PUCN, directed the Utilities to defer merger costs (including severance and related benefits) for a three-year period. The deferral of these costs is intended to allow adequate time for the anticipated savings from the merger to develop. At the end of the three-year period, the order instructed the Utilities to propose an amortization period for these costs, and allows SPPC and NPC to recover the costs to the extent that they are offset by merger savings. The Utilities have filed a case with the PUCN for recovery of these amounts and other merger costs. NPC and SPPC have proposed recovery over a 10-year period, and expect a decision on their filings by April 1, 2002 and June 1, 2002, respectively. At December 31, 2001, the remaining liability for unpaid severance was $0.4 million.

NOTE 17. DISCONTINUED OPERATIONS (SALE OF WATER BUSINESS)

On September 7, 2000, SPR and SPPC adopted a plan to sell SPPC's water utility business, and on June 11, 2001, SPPC closed the sale of its water business to the Truckee Meadows Water Authority (TMWA) for $341 million. SPPC recorded a $25.8 million gain on the sale, net of the refund described below and net of income taxes of $18.2 million. Included in the sale were facilities for water storage, supply, transmission, treatment and distribution, as well as accounts receivable and regulatory assets. Accounts receivable consisted of amounts due from developers for distribution facilities. Regulatory assets consisted primarily of costs incurred in connection with the Truckee River negotiated water settlement. Transfer of hydroelectric facilities included in the contract of sale for an additional $8 million will require action by the California Public Utilities Commission (CPUC). The sale agreement contemplates a second closing for the hydroelectric facilities to accommodate the CPUC's review of the transaction.

Pursuant to a stipulation entered into in connection with the sale and approved by the Public Utilities Commission of Nevada ("PUCN"), SPPC is required to hold in trust for refund to customers $21.5 million of the proceeds from the sale. The refund is being credited on the electric bills of SPPC's former water customers over a period not to exceed fifteen months from June 11, 2001. Under a service contract with TMWA, SPPC will provide, on an interim basis, customer service, billing, and meter reading services to TMWA.

Revenues from operations of the water business for the years ended December 31, 2001, 2000, and 1999 were $23 million, $57 million, and $54 million, respectively. The net income from operations of the water business, as shown in the Consolidated Statements of Income of SPR, includes (in thousands) preferred dividends of $200, $401, and $196 for the years ended December 31, 2001, 2000, and 1999, respectively. The income from operations of the water business, as shown in the Consolidated Statements of Income of SPPC, includes (in thousands) preferred dividends of $200, $401, and $528 for the years ended December 31, 2001, 2000, and 1999, respectively. These amounts are not included in the revenues and income (loss) from continuing operations shown in the accompanying income statements.

Purchased Power

NPC has three long-term contracts for the purchase of electric energy. One of these contracts commences in 2004 and expires in 2012. NPC's other contracts expire in 2016 and 2017. SPPC has one such contract that expires in 2009. Estimated future commitments under non-cancelable agreements with initial terms of one year or more at December 31, 2001, were as follows (dollars in thousands):

2002                       $ 46,440
2003                        152,852
2004                        151,627
2005                        136,680
2006                        137,446
2007 to 2017                777,064

According to the regulations of the Public Utility Regulator Policies Act, the Utilities are obligated, under certain conditions, to purchase the generation produced by small power producers and cogeneration facilities at costs determined by the appropriate state utility commission. Generation facilities that meet the specifications of the regulations are known as qualifying facilities (QFs). As of December 31, 2001, NPC had a total of 305 MWs of contractual firm capacity under contract with four QFs. The contracts terminate between 2022 and 2024. As of December 31, 2001, SPPC had a total of 109 MWs of maximum contractual firm capacity under 15 contracts with QFs. SPPC also had contracts with three projects at variable short-term avoided cost rates. One of SPPC's long-term QF contracts terminates in 2006, one terminates in 2039, and the rest terminate between 2014 and 2022.

Coal and Natural Gas

The Utilities have several long-term contracts for the purchase and transportation of coal and natural gas. These contracts expire in years ranging from 2006 to 2027. Estimated future commitments under non-cancelable agreements with initial terms of one year or more at December 31, 2001 were as follows (dollars in thousands):

                    Coal and Gas      Transportation
2002                    $ 42,870           $  78,255

2006                      18,045              76,254
2007 to 2023                   0             725,651

Leases

In 1984, NPC sold its administrative headquarters facility, less furniture and fixtures, for $27 million and entered into a 30-year capital lease of that facility with five-year renewal options beginning in year 31. The fixed rental obligation for the first 30 years is $5.1 million per year. Future cash rental payments as of December 31, 2001, were as follows (dollars in thousands):

139

2002                 $  6,156
2003                    6,156
2004                    6,946
2005                    7,736
2006                    7,736
2007 to 2014           58,016

The amount of imputed interest necessary to reduce the future cash rental payments to present value is $44 million as of December 31, 2001. Total interest expense on the lease obligation was $5.7 million and total amortization of the leased facility was $(278,000) for the year ended December 31, 2001. The total accumulated amortization of the leased facility on December 31, 2001, was $8.6 million.

SPPC has an operating lease for its corporate headquarters building. The primary term of the lease is 25 years, ending in 2010. The current annual rental is $5.4 million, which amount remains constant until the end of the primary term. The lease has renewal options for an additional 50 years.

SPR's estimated future minimum cash payments, including SPPC's headquarters building, under non-cancelable operating leases with initial terms of one year or more at December 31, 2001, were as follows (dollars in thousands):

2002                 $  12,127
2003                     9,284
2004                     8,194
2005                     7,289
2006                     6,863
2007 to 2045            63,463

Sale of Generation Assets

As a condition to its approval of the merger between SPR and NPC, the PUCN required the Utilities to file a Divestiture Plan for the sale of their electric generation assets. The PUCN approved a revised Divestiture Plan stipulation in February 2000. In May 2000 an agreement was announced for the sale of NPC's 14% undivided interest in the Mohave Generating Station ("Mohave"). In the fourth quarter of 2000 the Utilities announced agreements to sell six additional bundles of generation assets described in the approved Divestiture Plan. The sales were subject to approval and review by various regulatory agencies.

AB 369, which was signed into law on April 18, 2001, prohibits until July 2003 the sale of generation assets and directs the PUCN to vacate any of its orders that had previously approved generation divestiture transactions. In January 2001, California enacted a law that prohibits until 2006 any further divestiture of generation properties by California utilities, including SPPC, and could also affect any sale of NPC's interest in Mohave after July 2003 since the majority owner of that project is Southern California Edison. In addition, SPPC's request for an exemption from the requirements of a separate California law requiring approval of the CPUC to divest its plants was denied, subject to future refiling.

The sales agreements for the six bundles provide that they terminate eighteen months after their execution unless the parties agree to an earlier termination. The parties may extend the termination another six months to obtain additional regulatory approvals. As a result of the legislative and regulatory developments which have rendered the contracts impossible to perform, the Utilities are engaged in discussions with the buyers of the generation assets regarding the formal termination of the sales agreements and the related energy buyback contracts and interconnection agreements. As of December 31, 2001, NPC and SPPC had incurred costs of approximately $12.3 million and $15.5 million, respectively, in order to prepare for the sale of generation assets. The Utilities have requested recovery of these costs in each Utility's respective general rate case filing with the PUCN, discussed in Note 3, Regulatory Actions.

Environmental

Nevada Power Company

The Grand Canyon Trust and Sierra Club filed a lawsuit in the U.S. District Court, District of Nevada, in February 1998, against the owners (including NPC) of the Mohave Generation Station ("Mohave"), alleging violations of the Clean Air Act regarding emissions of sulfur dioxide and particulates. An additional plaintiff, National Parks and Conservation Association, later joined the suit. The plant owners and plaintiffs have had numerous settlement discussions and filed a proposed settlement with the court in October 1999. The consent decree, approved by the court in November 1999, established emission limits for sulfur dioxide and opacity and required installation of air pollution controls for sulfur dioxide, nitrogen oxides and particulate matter. The new emission limits must be met by January 1, 2006 and April 1, 2006 for the first and second units respectively. However, if the owners sell their entire ownership interest with a closing date prior to December 30, 2002, the new emission limits become effective 36 months and 39 months from the date of last closing for the two respective units. The estimated cost of new controls is $395 million. As a 14% owner in the Mohave Station, NPC's cost could be $55 million.

Also, the United States Congress authorized the EPA to study the potential impact Mohave may have on visibility in the Grand Canyon area. A final report of the study results was released in March 1999. The study acknowledges that sulfur dioxide emissions from Mohave are transported to the Grand Canyon. The EPA has solicited information to determine whether visibility impairment in the Grand Canyon can be reasonably attributed to Mohave. The EPA determined that significant visibility impairment to the Grand Canyon cannot be reasonably attributable to the station provided controls are installed as agreed to in the consent order. Therefore, the EPA will not require a Best Available Retrofit Technology Review. Provisions that were agreed to in the settlement will be reflected in the state Implementation Plan for Nevada.

In May 1997, NDEP ordered NPC to submit a plan to eliminate the discharge of Reid Gardner Station wastewater to groundwater. The NDEP order also required a hydrological assessment of groundwater impacts in the area. In June 1999, NDEP determined that wastewater ponds had degraded groundwater quality. In August 1999, NDEP issued a discharge permit to Reid Gardner Station and an order that requires all wastewater ponds to be closed or lined with impermeable liners over the next 10 years. This order also required NPC to submit a Site Characterization Plan to NDEP to ascertain impacts. This plan is under review by NDEP. After approval, an estimate of remediation costs will be determined by NPC. New pond construction and lining costs are estimated at $15 million.

Also, at the Reid Gardner Station, the NDEP has determined that there is additional groundwater contamination that resulted from oil spills at the facility. NDEP has required submitting a corrective action plan. The extent of contamination has been determined and remediation is occurring at a modest rate. An engineering evaluation of the current remediation technology will occur in 2002 to verify efficiency and to expedite remediation. Remediation modifications are not expected to materially affect the financial position of SPR or NPC.

In May 1999, NDEP issued an order to eliminate the discharge of NPC's Clark Station wastewater to groundwater. The order also required a hydrological assessment of groundwater impacts in the area. This assessment, submitted to NDEP in February 2001, warranted a Corrective Action Plan which was submitted to NDEP in November and is pending review. Remediation costs are expected to be in the $500,000 - $750,000 range. In addition to remediation, NPC will spend $789,000 to line existing ponds. After review and approval of the Corrective Action Plan by NDEP, NPC will implement remediation.

141

In July 2000, NPC received a request from the EPA for information to determine the compliance of certain generation facilities at the Clark Station with the applicable State Implementation Plan. In November 2000, NPC and the Clark County Health District entered into a Corrective Action Order requiring, among other steps, capital expenditures at the Clark Station totaling approximately $3 million. In March 2001, the EPA issued an additional request for information that could result in remediation beyond that specified in the November 2000 Corrective Action Order. If the EPA prevails, capital expenditures and temporary outages of four of Clark Station's generation units could be required. Additionally, depending on the time of year that the compliance activity and corresponding generation outage would occur, the incremental cost to purchase replacement energy could be substantial.

Sierra Pacific Power Company

In September 1994, Region VII of EPA notified SPPC that it was being named as a potentially responsible party (PRP) regarding the past improper handling of Polychlorinated Biphenyls (PCBs) by PCB Treatment, Inc., located in Kansas City, Kansas, and Kansas City, Missouri (the Sites). The EPA is requesting that SPPC voluntarily pay an undefined, pro rata share of the ultimate clean-up costs at the Sites. A number of the largest PRP's formed a steering committee, which is chaired by SPPC. The responsibility of the Committee is to direct clean-up activities, determine appropriate cost allocation, and pursue actions against recalcitrant parties, if necessary. The EPA issued an administrative order on consent requiring signatories to perform certain investigative work at the Sites. The steering committee retained a consultant to prepare an analysis regarding the Sites. The Site evaluations have been completed. EPA is developing an allocation formula to allocate the remediation costs. SPPC has recorded a preliminary liability for the Sites of $650,000 of which approximately $136,000 has been spent through December 31, 2001. Once evaluations are completed, SPPC will be in a better position to estimate and record the ultimate liabilities for the Sites.

Other Subsidiaries of SPR

LOS, a wholly owned subsidiary of SPR, owns property in North Lake Tahoe, California, which is leased to independent condominium owners. The property has both soil and groundwater petroleum contaminate resulting from an underground fuel tank that has been removed from the property. Additional contaminate from a third party fuel tank on the property has also been identified and is undergoing remediation. Estimated future remediation costs are not expected to be significant.

NEICO, a wholly owned subsidiary of SPR, owns property in Wellington, Utah, which was the site of a coal washing and load out facility. The site now has a reclamation estimate supported by a bond of $4 million with the Utah Division of Oil and Gas Mining. The property was under contract for sale and the contract required the purchaser to provide $1.3 million in escrow towards reclamation. However, the sales contract was terminated and NEICO took title to the escrow funds. In September 2000, NEICO leased the property together with an option to purchase. It is NEICO's intention to either lease or sell the property.

Other Commitments and Contingencies

SPR is a limited partner in an energy technology venture capital partnership formed to gain access to new technologies that could affect SPR and its subsidiaries. This partnership invests in energy companies offering technologies of strategic advantage to its partners. The initial term of this partnership expires in 2006, with two extensions of up to two years each. SPR's investment in the partnership was $4.7 million as of December 31, 2001, of which $325,000 was made in 2001. The remaining $300,000 balance of SPR's commitment is expected to be drawn, as funds are needed by the partnership during 2002. Gains and losses will be allocated 80% to the limited partners based on their contributions, and 20% to the general partner. SPR, as a limited partner, is entitled to 7.89%.

142

Certain of the Utilities' substations and portions of its generating stations, transmission, distribution, and communication systems are located on lands owned by units or agencies of federal, state and local governments under licenses, permits, easements (collectively, "rights"). Except for those granted in perpetuity, these rights may be canceled, with notice, at the will of the grantor. Certain rights may impose restrictions and obligations on the Utilities, including, but not limited to, care of property, limits on use, and the right of inspection. Certain of the rights obligate the Utilities to make periodic payments and may also allow the grantor to periodically reappraise the lands on which the Utilities' property is located. Such reappraisals, which may result in a change to the required periodic payments, may occur from annually to every five years. In connection with these rights, the Utilities incurred expenses of $1.41 million, $1.11 million and $1.38 million in 2001, 2000, and 1999, respectively.

Sierra Touch America LLC (STA), a partnership between SPC and Touch America, a subsidiary of Montana Power Company, is constructing a fiber optic line between Salt Lake City, Utah and Sacramento, CA. The conduits included in the line are under contract to be sold to AT&T, PF Net corporations, and STA. SPC is responsible for 50% of the partnership's operating expenses and shares in the construction cost of the fiber network. Construction activity between Sacramento and Reno commenced in July 2000, and the estimated completion date has been moved to early 2003. Williams Communications, LLC ("Williams") has filed a complaint in United States District Court alleging that STA has failed to make timely payment on invoices in connection with a construction agreement between Williams and STA. TI Energy Services ("TI") has filed a complaint in the District Court of Harris County, Texas, alleging that STA has failed to make timely payment on invoices in connection with a services agreement between TI and STA, whereby TI is to provide services for certain segments of the fiber optic line. Although SPC's ultimate liability, if any, cannot be estimated, Management believes the final outcome of the litigation is not likely to have a material adverse effect on SPR's financial position or results of operations.

SPPC owns a 345 kV transmission line that connects SPPC to the facilities of the Bonneville Power Administration ("BPA") near Alturas, California. The Transmission Agency of Northern California ("TANC") initiated proceedings in the United States District Court for the Eastern District of California and the United States Court of Appeals for the Ninth Circuit, in each case alleging that BPA's construction of a small portion of the Alturas Intertie violated the Northwest Power Preference Act and requesting an injunction prohibiting operation of the Alturas Intertie. The case before the Eastern District was dismissed for lack of jurisdiction. The case before the Ninth Circuit was dismissed for TANC's failure to prosecute. In December 1999, TANC filed suit in the Superior Court of the State of California, Sacramento County, seeking an injunction against operation of the Alturas Intertie based on numerous allegations under state law, including inverse condemnation, trespass, private nuisance, and conversion. That case was removed to Federal Court and dismissed by the trial court, and is now on appeal in the Ninth Circuit. Although SPPC's ultimate liability, if any, cannot be estimated at this time, Management believes the final outcome of the appeal and any subsequent litigation is not likely to have a material adverse effect on SPR's financial position or results of operation.

SPR and its subsidiaries, through the course of their normal business operations, are currently involved in a number of other legal actions, none of which has had or, in the opinion of management, is expected to have, a significant impact on its financial position or results of operations.

See Notes 3, 5, 6, 7, 8, 9, 12, 14, and, 16 of SPR's consolidated financial statements for additional commitments and contingencies.

NOTE 19. SEGMENT INFORMATION

SPR operates three business segments (as defined by FASB statement No. 131, Disclosure about Segments of an Enterprise and Related Information) providing regulated electric, natural gas and water service. Electric service is provided to Las Vegas and surrounding Clark County, northern Nevada and the Lake Tahoe

143

area of California. Natural gas and water services are provided in the Reno-Sparks area of Nevada. Other segment information includes segments below the quantitative threshold for separate disclosure.

On September 7, 2000, SPR and SPPC adopted a plan to sell SPPC's water utility business. Accordingly, the water business is reported as a discontinued operation and the consolidated financial statements have been reclassified to report separately the net assets and operating results of the water business. Therefore the water business is not reflected in the segment information below.

Operational information of the different business segments is set forth below based on the nature of products and services offered. SPR evaluates performance based on several factors, of which the primary financial measure is business segment operating income. The accounting policies of the business segments are the same as those described in Note 1, Summary of Significant Accounting Policies. Intersegment revenues are not material.

In accordance with the requirements of purchase accounting and based on a merger date of August 1, 1999, the segmented financial information for the period ended December 31, 1999, includes five months of operating activity for SPR's subsidiaries other than NPC.

NOTE 22. DERIVATIVES AND HEDGING ACTIVITIES (SPR, NPC, SPPC)

Effective January 1, 2001, SPR, SPPC, and NPC adopted Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS No. 138, both issued by the Financial Accounting Standards Board. As amended, SFAS No. 133 requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position, measure those instruments at fair value, and recognize changes in the fair value of the derivative instruments in earnings in the period of change unless the derivative qualifies as an effective hedge.

The adoption of this standard did not have a material impact on the earnings of SPR or the Utilities. SPR and the Utilities did, however, recognize all derivatives as assets or liabilities in the condensed consolidated balance sheets upon adoption and measured those instruments at fair value. This resulted in SPR, NPC, and SPPC recording $981 million, $678 million, and $303 million of risk management assets, respectively, and $822 million, $722 million, and $97 million of risk management liabilities, respectively, at January 1, 2001.

On April 18, 2001, AB 369 was signed into law in Nevada. AB 369 reinstated deferred energy accounting by the Utilities effective March 1, 2001. (See Note 3
- Regulatory Actions, above.) As a result, fuel and purchased power expenses, including gains and losses on derivative instruments, are recoverable or payable through future rates. In accordance with SFAS No. 71, "Accounting for the Effects of Certain Types of Regulation," regulatory assets and liabilities are established to the extent that such derivative gains and losses are recoverable or payable through future rates. Because of this accounting treatment, the Utilities will not apply hedge accounting to their electricity and natural gas derivatives. However, SPR and the Utilities have adopted cash flow hedge accounting for other derivative instruments not subject to regulatory treatment. The transition adjustments resulting from adoption of SFAS No. 133 related to the other derivative instruments not subject to regulatory treatment was reported as the cumulative effect of a change in accounting principle in Other Comprehensive Income of SPR and the Utilities.

SPR's and the Utilities' objective in using derivatives is to reduce exposure to energy price risk and interest rate risk. Energy price risks result from activities that include the generation, procurement and marketing of power and the procurement and marketing of natural gas. Derivative instruments used to manage energy price risk include forwards, options, and swaps. These contracts allow the Utilities to reduce the risks associated with volatile electricity and natural gas markets.

Derivatives used to manage interest rate risk include interest rate swaps designed to moderate exposure to interest-rate changes and lower the overall cost of borrowing. At December 31, 2001, SPR had one interest rate swap related to $200 million of SPR floating rate notes maturing April 20, 2003. This interest rate swap is considered a completely effective cash flow hedge.

At December 31, 2001, the fair value of the derivatives resulted in the recording of $347 million, $250 million and $97 million in risk management assets and $1.019 billion, $601 million and $410 million in risk management liabilities in the Consolidated Balance Sheets of SPR, NPC and SPPC, respectively. The fair values of the forward contracts and swaps are determined based on quotes obtained from independent brokers and exchanges. The fair values of options are determined using a pricing model which incorporates assumptions such as the underlying commodity's forward price curve, time to expiration, strike price, interest rates, and volatility. The use of different assumptions and variables in the model could have a significant impact on the valuation of the instruments.

Due to the regulatory environment in which the Utilities operate, regulatory assets and liabilities are established to the extent that electricity and natural gas derivative gains and losses are recoverable or payable through future rates. Accordingly, at December 31, 2001, $664 million, $351 million and $313 million in net

147

risk management regulatory assets were recorded in the Consolidated Balance Sheets of SPR, NPC, and SPPC, respectively. In addition, for the twelve months ended December 31, 2001, the unrealized gains and losses resulting from the change in the fair value of derivatives designated and qualifying as cash flow hedges for SPR, NPC, and SPPC were recorded in Other Comprehensive Income. Such amounts will be reclassified into earnings when the related transactions are settled or terminate. No amounts were reclassified into earnings during the twelve months ended December 31, 2001.

Management has evaluated the impact of Derivatives Implementation Group Issues C10 and C15 with respect to option contracts and optionality features. In Management's opinion, the implementation of these interpretations will not result in any changes to the initial application of SFAS No. 133 nor have a significant impact on the financial position or results of operations of SPR or the Utilities.

------------------------------------------------------------------------------------------------------------------------------------

1. Mr. Rigazio was President of Nevada Power Company until the appointment of Mr. Ruelle to that position in May 2001.
2. The amounts presented for 1999 represent incentive pay received pursuant to SPR's "pay for performance" team incentive plan approved by stockholders in May, 1994. All of the amounts are reported in the year they were earned, although payment may have occurred in a subsequent reporting period. The Board of Directors elected not to grant payment of the 2000 and 2001 incentive pay to the executives.
3. For all of the executives listed these amounts represent Personal Time Off payouts.
4. As the result of a promotion, Mr. Ruelle was awarded a restricted stock grant of 4,000 shares with dividend equivalents. At December 31, 2001, the value of the grant was $60,200 at $15.05 per share. The grant will vest over a four year period at 25% per year. In 2000, Mr. Higgins was awarded a restricted stock grant of 16,000 shares with dividend equivalents. At December 31, 2001, the value of the grant was $240,800 at $15.05 per share. The grant will vest over a four year period in the following manner:

155

September 2002             4,000 shares
September 2003             4,000 shares
September 2004             8,000 shares

5. As a result of the August 1, 1999 merger with Nevada Power Company, all SPR nonqualifying stock options outstanding as of that date were converted at a ratio of 1.44:1. For the pre-merger SPR executives, the 1999 option amounts include the number of new shares issued during the year, as well as the total number of shares that were converted for that employee. The 2000 Non-Qualified Stock Options were granted in August of 1999 and are therefore included in the 1999 amounts.

6. The Long-term incentive payouts for the SPR executives, for the three-year periods ended December 31, 1999 and December 31, 2001, were not approved for payment by the SPR Board of Directors; therefore, for these payouts, zero amounts are shown in 1999 for the pre-merger SPR executives, and in 2001 for all executives. In 1999, Nevada Power executives received a lump sum payout of all their performance shares as a result of the August 1, 1999 merger.

7. Amounts for All Other Compensation include the following for 2001:

1. Under the SPR executive long-term incentive plan, the 2001 grants of nonqualifying stock options were made on January 1, 2001. One-third of these grants vest annually commencing one year after the date of the grant. An additional grant of 40,000 shares of nonqualifying stock options was made to Mr. Ruelle as the result of a promotion. This grant vests at a rate of one-quarter per year for four years beginning one year after the grant date of May 22, 2001.

2. The total number of nonqualifying stock options granted to all employees in 2001 was 414,530.

3. The hypothetical grant-date present values are calculated under the Black-Scholes Model. The Black-Scholes Model is a mathematical formula used to value options traded on stock exchanges. The assumptions used in determining the option grant date present values listed above include the stock's average expected volatility (32.31%), average risk free rate of return (5.32%), average projected dividend yield (4.99%), the stock option term (10 years), and an adjustment for risk of forfeiture during the vesting period (4 years at 3%). No adjustment was made for non-transferability.

Long-Term Incentive Plans-Awards in Last Five Years

The executive long-term incentive plan (LTIP) provides for the granting of stock options (both nonqualified and qualified), stock appreciation rights (SARs), restricted stock performance units, performance shares and bonus stock to participating employees as an incentive for outstanding performance. Incentive compensation is based on the achievement of pre-established financial goals for SPR. Goals are established for total shareholder return (TSR) compared against the Dow Jones Utility Index and annual growth in earnings per share (EPS).

The following table provides information as to the performance shares granted to the named executive officers of Sierra Pacific Resources in 2001. Nonqualifying stock options granted to the named executives as part of the LTIP are shown in the table "Option/SAR Grants in Last Fiscal Year."

---------------------------------------------------------------------------------------

SPR's noncontributory qualified retirement plan provides retirement benefits to eligible employees upon retirement at a specified age. Annual benefits payable are determined by a formula based on years of service and final average earnings consisting of base salary and incentive compensation. Remuneration for the named executives is the amount shown in columns (c) and (d) of the Summary Compensation Table. Pension costs of the retirement plan, to which SPR contributes 100% of the funding, are not and cannot be readily allocated to individual employees and are not subject to Social Security or other offsets.

The years of credited service under the qualified retirement plan for the named executives are as follows: Mr. Higgins 5.5, Mr. Ruelle 4.7, Mr. Rigazio 17.4, Mr. Peterson 8.4, Mr. Ceccarelli 27.3, and Mr. Oldham 25.2.

A supplemental executive retirement plan (SERP) and a restoration plan are also offered to the named executive officers. The SERP is intended to ensure the payment of a competitive level of retirement income to attract, retain and motivate selected executives. The Restoration Plan is intended to provide benefits to executive officers whose benefits cannot be paid under the qualified plan because of salary deferrals to the Non-Qualified Deferred Compensation Plan, IRS limitations on compensation that can be recognized by a qualified plan, and IRS limitations on benefits payable from a qualified plan.

The years of credited service under the non-qualified SERP are as follows: Mr. Higgins 8.1, Mr. Ruelle 4.7, Mr. Rigazio 17.4, Mr. Peterson 16.4, Mr. Ceccarelli 27.3, and Mr. Oldham 25.2.

Severance Arrangements

Individual severance allowance plans exist for the named executive officers which provide for severance pay, payable in a lump sum or by purchase of an annuity, if within three years after a change in control of SPR, there is a termination of employment by SPR related to such change in control, or a termination of employment by the employee for good reason, in each case as described in the plans. In these circumstances, officers are entitled to a severance allowance not to exceed an amount equal to 36 months of the officer's base salary and any bonus and the continuation for up to 36 months of participation in SPR's group medical and life insurance plans. Change in control is defined in the plans as, among other things, a dissolution or liquidation, a reorganization, merger or consolidation in which SPR is not the surviving corporation, the sale of all or substantially all the assets of SPR (not the sale of a work unit) or the acquisition by any person or entity of 30% or more of the voting power of SPR.

159

In addition, several merger-related and merger-conditioned severance arrangements have been entered into between SPR and several executives, which are described in Item 13 - Certain Relationships and Related Transactions.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions with Management

Mr. Peterson, formerly a partner with the law firm of Woodburn and Wedge, became Senior Vice President and General Counsel for Sierra Pacific Resources in 1993. Woodburn and Wedge, which has performed legal services for SPPC since 1920 and for Sierra Pacific Resources and all of its subsidiaries from their inception, continues to perform legal work for SPR. Mr. Peterson's spouse, an equity partner in the firm since 1982, has performed work for SPR since 1976 and continues to do so from time to time.

Susan Oldham, a former employee of SPPC specializing in water resources law, planning and policy, accepted SPPC's voluntary severance offering in December 1995. Ms. Oldham is the spouse of Steven C. Oldham, Senior Vice President, Energy Supply, for NPC and SPPC. Ms. Oldham, a licensed attorney in Nevada and California, performed specialized legal services in the water resources area for SPR on a contract basis through June 2001.

Change in Control Agreements

SPR has entered into change in control severance agreements with Walter M. Higgins, Jeffrey L. Ceccarelli, Steven C. Oldham, William E. Peterson, Mark A. Ruelle, Victor H. Pena, Dennis D. Schiffel, Mary

162

O. Simmons, Susan Brennan, Carol Marin, Paul Heagen, Richard K. Atkinson, John Brown, Douglas R. Ponn, Michael R. Smart, Matt H. Davis, and Mary Jane Reed. These agreements provide that, upon termination of the executive's employment within 24 or 36 months following a change in control of SPR (as defined in the agreement either (a) by SPR for reasons other than cause (as defined in the agreements), (b) death or disability, or (c) by the executive for good reason as defined in the agreement, including a diminution of responsibilities, compensation, or benefits (unless, with respect to reduction in salary or benefits, such reduction is applicable to all senior executives of SPR and the acquirer)), the executive will receive certain payments and benefits. These severance payments and benefits include (i) a lump sum payment equal to two or three times the sum of the executive's base salary and target bonus, (ii) a lump sum payment equal to the present value of the benefits the executive would have received had he continued to participate in SPR's retirement plans for an additional two or three years (or, in the case of SPR's Supplemental Executive Retirement Plan only, the greater of three years or the period from the date of termination until the executive's early retirement date, as defined in such plan), and (iii) continuation of life, disability, accident and health insurance benefits for a period of 24 or 36 months immediately following termination of employment. The agreements also provide that if any compensation paid, or benefit provided, to the executive, whether or pursuant to the change in control agreements, would be subject to the federal excise tax on "excess parachute payments," payments and benefits provided pursuant to the agreement will be cut back to the largest amount that would not be subject to such excise tax, if such cutback results in a higher after-tax payment to the executive. The Board of Directors entered into these agreements in order to attract and retain excellent management and to encourage and reinforce continued attention to the executives' assigned duties without distraction under circumstances arising from the possibility of a change in control of SPR. In entering into these agreements, the Board was advised by Towers Perrin, the national compensation and benefits consulting firm described above, and Skadden, Arps, Slate, Meagher & Flom, an independent outside law firm, to insure that the agreements entered into were in line with existing industry standards, and provided benefits to management consistent with those standards. The new contracts expire on December 31, 2003, unless renewed or replaced before that time.

Employment Agreements

Walter M. Higgins

On August 4, 2000, SPR elected Walter M. Higgins as President, Chief Executive Officer and Chairman of the Board under terms and conditions of an employment offer. The terms and conditions of that agreement essentially replicate Mr. Higgins' compensation and benefits package provided by his previous employer, AGL Resources, and make him whole for benefits and compensation lost, forgone, or otherwise forfeited as a result of his accepting employment with SPR.

SPR engaged Towers Perrin to evaluate Mr. Higgins' offer prior to consummating it in order to assure that it was consistent with SPR policy to compensate its senior executives, including the Chief Executive Officer, at or near the midpoint of the competitive market for base salary and incentive compensation opportunities for executives of comparably sized companies in general industry.

The employment agreement with Mr. Higgins provides for an annual base salary of $590,000, participation in SPR's short-term incentive program, at 65% of base pay, and participation in SPR's long-term incentive program approved by shareholders at 140% of base salary. Payments are based on corporate and personal performance targets established under terms and conditions of the plan. The agreement also provides that Mr. Higgins will be paid long-term incentives in accordance with the terms of the plan approved by shareholders in 1994, which contemplates a performance share grant of 13,200 shares effective January 2001, to be earned over a three-year period under performance measurements relating to financial performance and total shareholder return. Effective January 1, 2001, he also received 104,000 non-qualified stock options, which will vest at one-third per year. As with the officer group as a whole, the strike price will be fixed at the average daily closing price of the stock on the New York Stock Exchange for the 30-day period January 1-31. In

163

addition, Mr. Higgins will be eligible to receive on a pro-rata basis (28 of 36 months) the 2000-2002 performance share grants, which are also earned based on targets relating to financial performance and total shareholder return. Mr. Higgins also received a one-time restricted stock grant of 16,000 shares with dividend equivalents, grossed-up for taxes, which will vest over a four-year period. Mr. Higgins is required to accumulate and maintain, over five years, two times annual compensation in SPR stock, and was also granted 400,000 non-qualified stock options at a strike price based on the closing stock price on the day he accepted employment with SPR, which will vest 25% per year or sooner if certain price threshold levels are met. Mr. Higgins is also eligible to participate in SPR's Supplemental Executive Retirement Plan and was provided credit for all previous years of service with SPR, plus all years served at AGL Resources or Louisville Gas & Electric, with benefits reduced by any qualified benefits received from that prior employment. Mr. Higgins was also provided $2,000,000 of life insurance coverage at SPR expense and is otherwise eligible to participate in all employer-sponsored health, pension, benefit, and welfare plans. In the event Mr. Higgins is terminated by SPR for any reason other than cause (as defined in the agreement), he will receive one year's base salary and annual incentive payment, subject to execution of an appropriate release and non-compete covenants. In the event of a termination resulting from a change in control, within 24 months following a change in control of SPR (as defined in the agreement either (a) by SPR for reasons other than cause (as defined in the agreement), (b) death or disability, or (c) by Mr. Higgins for good reason as defined in the agreement, including a diminution of responsibilities, compensation, or benefits (unless, with respect to reduction in salary or benefits, such reduction is applicable to all senior executives of SPR and the acquirer)), he will receive certain payments and benefits. This severance payment and benefit include (i) a lump sum payment equal to three times the sum of his base salary and target bonus, (ii) a lump sum payment equal to the present value of the benefits he would have received had he continued to participate in SPR's retirement plans for an additional three years (or, in the case of SPR's Supplemental Executive Retirement Plan only, the greater of three years or the period from the date of termination until the executive's early retirement date, as defined in such plan), and (iii) continuation of life, disability, accident and health insurance benefits for a period of 36 months immediately following termination of employment.

Under the employment agreement, SPR will pay any additional amounts sufficient to hold Mr. Higgins harmless for any excise tax that might be imposed as a result of being subject to the federal excise tax on "excess parachute payments" or similar taxes imposed by state or local law in connection with receiving any compensation or benefits that are considered contingent on a change in control.

A change in control for purposes of the Employment Agreement occurs (i) if SPR merges or consolidates, or sells all or substantially all of its assets, and less than 65% of the voting power of the surviving corporation is owned by those stockholders who were stockholders of SPR immediately prior to such merger or sale; (ii) any person acquires 20% or more of SPR's voting stock; (iii) SPR enters into an agreement or SPR or any person announces an intent to take action, the consummation of which would otherwise result in a change in control, or the Board of Directors of SPR adopts a resolution to the effect that a change in control has occurred; (iv) within a two-year period, a majority of the directors of SPR at the beginning of such period cease to be directors; or (v) the stockholders of SPR approve a complete liquidation or dissolution of SPR.

Steven W. Rigazio

On August 31, 2000, SPR entered into an employment agreement with Steven W. Rigazio, President of Nevada Power. Under the terms of the agreement, Mr. Rigazio will be paid $255,000 in annual base salary, subject to adjustment if the Board determines that an adjustment is appropriate. In addition, Mr. Rigazio is entitled to receive annual incentive and long-term compensation in accordance with the terms and conditions of existing plans as apply to the officer group as a whole. If Mr. Rigazio becomes disabled during the course of his employment, he will be entitled to receive 100% of base salary for six months, and any annual incentive pay for which he would otherwise be eligible during the year he first went on disability. At the expiration of any short-term disability, Mr. Rigazio would be eligible for long-term disability under SPR's long-term disability

164

plan and will continue to be covered by SPR's medical, vision and dental plans during all of such time and will continue to earn years of service under the Retirement Plan until age 65 at which time he will be required to retire. During such time, he will also receive life insurance benefits substantially similar to those he was entitled to receive before going on short-term disability or long-term disability. If Mr. Rigazio dies before age 55 (the Retirement Plan's earliest retirement date), his surviving spouse will be eligible to receive the Retirement Plan's pre-retirement death benefit at the time Mr. Rigazio would have become 55. If Mr. Rigazio dies while on short-term disability or long-term disability, his surviving spouse will be eligible for SERP benefits as if Mr. Rigazio were 62 and will be paid an annuity on the date of death, or when Mr. Rigazio would have reached age 55, whichever occurs later. In addition, SPR will continue to provide the Employee's spouse and eligible dependents all medical coverage so long as they are not covered by other plans. Mr. Rigazio died on December 27, 2001, and the payments described above were made.

David G. Barneby

On June 19, 1999, Nevada Power, a wholly owned subsidiary of SPR, entered into a retention agreement effective on the date of the merger with David G. Barneby, Vice President, Generation, which provides him with benefits which he would have been entitled to receive had he voluntarily terminated his original May 13, 1998, employment agreement with SPR. The agreement provides, in addition to base pay and any incentive pay or long-term pay accrued during the period of his employment, an additional $600,890 in cash, payable in substantially equal quarterly installments commencing on October 1, 1999, and ending on July 31, 2002. If employment is terminated during the term or if the employee dies during the term, any remaining and unpaid installments shall be paid to the employee or to his heirs. If the employee is terminated or retires, then the employee shall, in addition, receive the economic equivalent to an enhancement of his retirement allowing for payment in cash of the present value of the average early retirement benefit calculated on the basis of the greater of actual age or age 55, and an additional five years of age or years of service or a combination thereof to maximize retiree medical benefits. The employee is also entitled to 24 months of employee health and life benefits in amounts substantially equivalent to those in effect immediately prior to termination. Mr. Barneby retired on January 1, 2002.

In the event any payments or benefits or distributions thereof under the contract or any other agreements, policies, or plans of SPR would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code by reason of being considered contingent on a change of control, then the employee is entitled to receive an additional payment equal to such excise tax.

The Global Certificate shall not be transferable or exchangeable, nor shall any purported transfer be registered, except as follows:

2

(i) the Global Certificate may be transferred in whole, and appropriate registration of transfer effected, if such transfer is by such nominee to the Depositary, or by the Depositary to another nominee thereof, or by any nominee of the Depositary to any other nominee thereof, or by the Depositary or any nominee thereof to any successor securities depositary or any nominee thereof; and

(c) to the extent that the provisions of clause
(q) of paragraph 1 conflicts with any other provisions of the Indenture or the Series B Notes, the provisions of this clause (q) of Paragraph 1 shall control; and

(d) the rights of such beneficial owners shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such beneficial owners or of any agent member of, or direct or indirect participants in, the Depositary and the Depositary or the depositary participants.

3

The IAI Notes shall be delivered to each IAI in the manner specified by such IAI upon receipt by the Company of a satisfactorily completed purchaser's letter in the form attached hereto as Exhibit B. The IAI Notes shall not be transferable or exchangeable, nor shall any purported transfer be registered, except upon presentation of evidence satisfactory to the Company and the transfer agent that such Notes are being offered, resold, pledged or otherwise transferred only (i) in the United States to a person whom the seller reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A, (ii) outside the U.S. in a transaction complying with the provisions of Rule 904 under the Securities Act, (iii) pursuant to an exemption from registration under the Securities Act provided by Rule
144 (if available) or (iv) pursuant to an effective registration statement under the Securities Act, in each of cases (i) through (iv) in accordance with any applicable securities laws of any State of the United States. The IAI Notes shall bear the legends for restricted securities set forth in Exhibit A hereto and the following additional legend:

"IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE COMPANY AND THE SECURITIES REGISTRAR AND/OR TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS THE COMPANY AND SUCH SECURITIES REGISTRAR AND/OR TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS."

(r) Not applicable.

(s) The Series B Notes have not been registered under the Securities Act and may not be offered, sold or otherwise transferred in the absence of such registration or an applicable exemption therefrom. No service charge shall be made for the registration of transfer or exchange of the Series B Notes, or any Tranche thereof; provided, however,

4

that the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with the exchange or transfer.

(t) For purposes of the Series B Notes, "Business Day" shall mean any day, other than Saturday or Sunday, on which commercial banks and foreign exchange markets are open for business, including dealings in deposits in U.S. dollars, in New York.

(ii) (A) an instrument wherein the Company, notwithstanding the satisfaction and discharge of its Indebtedness in respect of the Bonds, shall assume the obligation (which shall be absolute and unconditional) to irrevocably deposit with the Trustee such additional sums of money, if any, or additional Government Obligations, if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Government Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due and to become due on such bonds or portions thereof; provided, however, that such instrument may state that the obligation of the Company to make additional deposits as aforesaid shall be subject to the delivery to the Company by the Trustee of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing showing the calculation thereof; and (B) an opinion of tax counsel in the United States reasonably acceptable to the Trustee to the effect that the Holders of the outstanding Bonds will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

The Series B Notes shall have such other terms and provisions as are provided in the form thereof attached hereto as Exhibit A, and shall be issued in substantially such form.

Except as otherwise provided in said Indenture, any such interest not so paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 15 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the


requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of and premium, if any, on this Security and interest hereon at Maturity shall be made upon presentation of this Security at the office of the Corporate Trust Administration of The Bank of New York located at 101 Barclay Street, New York, New York 10286 or at such other office or agency as may be designated for such purpose by the Company from time to time. Payment of interest on this Security (other than interest at Maturity) shall be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, except that if such Person shall be a securities depositary, such payment may be made by such other means in lieu of check, as shall be agreed upon by the Company, the Trustee and such Person. Payment of the principal of and premium, if any, and interest on this Security, as aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts.

If any Interest Payment Date for this Note (other than an Interest Payment Date at Maturity) would otherwise be a day that is not a Business Day (as defined herein), such Interest Payment Date shall be postponed until the next succeeding Business Day unless such Business Day falls in the next calendar month, in which case such Interest Payment Date shall be the next preceding Business Day. If the Maturity of this Note falls on a day that is not a Business Day, the payment of principal and interest will be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such Stated Maturity, except as otherwise expressly provided for herein.

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and issuable in one or more series under and equally secured by a General and Refunding Mortgage Indenture, dated as of May 1, 2001 (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the "Indenture"), between the Company and The Bank of New York, trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities are, and are to be, authenticated and delivered and secured. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Security is one of the series designated above.

The period beginning on, and including, October 18, 2001 and ending on, but excluding, the first Interest Payment Date and each successive period beginning on, and including, an Interest Payment Date and ending on, but excluding, the next succeeding Interest Payment Date is herein called an "Interest Period."

The rate of interest payable from time to time in respect of this Note (the "Rate of Interest") will be a floating rate determined by reference to LIBOR, determined as described below, plus a margin of 1.65% per annum. All percentages resulting from any calculation on this Note will be rounded to the nearest one hundredth-thousandth of a percentage point, with five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculation on the Notes will be rounded to the nearest cent (with one-half cent being rounded upward).

2

(a) At approximately 11:00 a.m. (London time) on the second day on which commercial banks are open for business (including dealings in U.S. Dollar deposits) in London (or, for purposes of paragraph (c)(ii) below, New York) prior to the commencement of the Interest Period for which such rate will apply (each such day an "Interest Determination Date"), The Bank of New York, or its successor in this capacity (the "Calculation Agent"), will calculate the Rate of Interest for such Interest Period as, subject to the provisions described below, the rate per annum equal to 1.65% above the rate appearing on the British Bankers Association Telerate Page 3750 (or such other page as may replace that page on the British Bankers Association Telerate Service) for three-month U.S. dollar deposits in the London inter-bank market on such Interest Determination Date.

(b) If on any Interest Determination Date an appropriate rate cannot be determined from the British Bankers Association Telerate Service, the Rate of Interest for the next Interest Period shall, subject to the provisions described below, be the rate per annum that the Calculation Agent certifies to be 1.65% per annum above the arithmetic mean of the offered quotations, as communicated to and at the request of the Calculation Agent by not less than two major banks in London selected by the Calculation Agent (the "Reference Banks," which expression shall include any successors nominated by the Calculation Agent), to leading banks in London by the principal London offices of the Reference Banks for three-month U.S. dollar deposits in the London inter-bank market as at 11:00 a.m. (London time) on such Interest Determination Date.

(c) If on any Interest Determination Date fewer than two of such offered rates are available, the Rate of Interest for the next Interest Period shall be whichever is the higher of:

(i) the Rate of Interest in effect for the last preceding Interest Period to which (a) or (b) above shall have applied; and

(ii) the Reserve Interest Rate. The "Reserve Interest Rate" shall be the rate per annum which the Calculation Agent determines to be 1.65% per annum above either (1) the arithmetic mean of the U.S. dollar offered rates which New York City banks selected by the Calculation Agent are or were quoting, on the relevant Interest Determination Date, for three-month deposits to the Reference Banks or those of them (being at least two in number) to which such quotations are or were, in the opinion of the Calculation Agent, being so made, or (2) in the event that the Calculation Agent can determine no such arithmetic mean, the arithmetic mean of the U.S. dollar offered rates which at least two New York City banks selected by the Calculation Agent are or were quoting on such Interest Determination Date to leading European banks for a period of three months; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as mentioned above, the Rate of Interest shall be the Rate of Interest specified in (i) above.

The Calculation Agent shall, as soon as practicable after 11:00 a.m. (London time) on each Interest Determination Date, determine the Rate of Interest and calculate the amount of interest payable in respect of the following Interest Period (the "Interest Amount"). The Interest Amount shall be calculated by applying the Rate of Interest to the principal amount of each Note outstanding at the commencement of the Interest Period, multiplying each such amount by the actual number of days in the Interest Period concerned (which actual number of days shall include the first day but exclude the last day of such Interest Period) divided by 360 and rounding the resultant figure upwards to the nearest cent (half a cent being rounded upwards). The determination of the Rate of Interest and the Interest Amount by the Calculation Agent shall (in the absence of willful default, bad faith or manifest error) be final and binding on all parties.

3

Notwithstanding anything herein to the contrary, the interest rate on the Notes shall in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

Interest shall cease to accrue on this Note on Maturity unless, upon presentation of this Note, payment of principal is improperly withheld or refused, in which case, interest shall continue to accrue.

So long as any of this Note remains outstanding, the Company shall maintain under appointment a Calculation Agent, which shall initially be the Trustee, to calculate the Rate of Interest payable on this Note in respect of each Interest Period. If the Calculation Agent shall fail to establish the Rate of Interest for any Interest Period, or if the Company shall remove the Calculation Agent, the Company shall appoint another commercial or investment bank to act as the Calculation Agent. The Company may change the Calculation Agent without notice.

All certificates, communications, opinions, determinations, calculations, quotations and decisions given, expressed, made or obtained for the purposes of the provisions hereof relating to the payment and calculation of interest on this Note by the Calculation Agent shall (in the absence of willful default, bad faith or manifest error) be binding on the Company, the Calculation Agent and all of the holders and owners of beneficial interests in this Note, and no liability shall (in the absence of gross negligence, bad faith or willful misconduct) attach to the Calculation Agent in connection with the exercise or non-exercise by it of its powers, duties and discretions.

The Securities of this series will not be entitled to the benefit of any sinking fund or other voluntary or mandatory redemption provisions.

If an Event of Default shall occur and be continuing, the principal of this Security may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Trustee to enter into one or more supplemental indentures for limited purposes without the consent of any Holders of Securities. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

4

As provided in the Indenture and subject to certain limitations therein set forth, this Security or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and, at the election of the Company, the Company's entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient to pay when due the principal of and interest on this Security when due.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office of The Bank of New York in New York, New York or such other office or agency as may be designated by the Company from time to time, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series of authorized denominations and of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only as registered Securities, without coupons, and in denominations of $100,000 and integral multiples of $1000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of the same series and Tranche, of any authorized denominations, as requested by the Holder surrendering the same, and of like tenor upon surrender of the Security or Securities to be exchanged at the office of The Bank of New York in New York, New York or such other office or agency as may be designated by the Company from time to time.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Securities shall be governed by and construed in accordance with the laws of the State of New York.

As used herein, "Business Day" shall mean any day, other than a Saturday or Sunday, on which commercial banks and foreign exchange markets are open for business, including dealings in deposits in U.S. dollars, in New York. All other terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

As provided in the Indenture, no recourse shall be had for the payment of the principal of or premium, if any, or interest on any Securities, or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under the Indenture, against, and no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, officer or director, as such, past, present or future of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and

5

understood that the Indenture and all the Securities are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities.

Unless the certificate of authentication hereon has been executed by the Trustee or an Authenticating Agent by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

(which Indenture of Mortgage and Deed of Trust as so amended and supplemented is hereinafter in this Bond called the "Indenture"), executed by the Company to Bankers Trust Company (successor to First Interstate Bank of Nevada, N.A., formerly First National Bank of Nevada, Reno, Nevada) ("Trustee"), as Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the terms and conditions upon which the Bonds of Series BB are and are to be secured and the rights, duties and immunities thereunder of the holders or registered owners thereof, of the Company, and of the Trustee. As provided in the Indenture, said Bonds may be issued in series, for various principal sums, may bear different dates and mature at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided or permitted. The Bonds of Series BB are described in said Twenty-Eighth Supplemental Indenture dated as of July 1, 2001 ("Twenty-Eighth Supplemental Indenture") executed by the Company to Bankers Trust Company, as Trustee, and are issuable as single registered bonds.

Said Indenture, among other things, provides that no bondholder or bondholders may institute any suit, action or proceeding for the collection of this Bond, or claim for interest thereon, or to enforce the lien of said Indenture, if and to the extent that the institution or prosecution thereof or the entry of a judgment or a decree therein would, under applicable law, result in the surrender, impairment, waiver or loss of the lien of said Indenture upon any property subject thereto.

This Bond shall be deemed to be prepaid at any time if and to the extent that (1) the Company shall elect to prepay installments payable under

Section 8.1 of the Clark County Agreement and to cause the Clark County Bonds to be redeemed, in whole or in part, pursuant to Section 3.01(A)(5) of the Clark County Indenture, or (2) subject to Section 11.03 of the Indenture, the

Company shall be obligated to prepay installments payable under Sections 11.03 and 11.07 of the Clark County Agreement and to cause the Clark County Bonds to be redeemed, in whole or in part, upon the occurrence of an event specified in
Section 3.01(B) of the Clark County Indenture. In any such event this Bond shall be deemed to be prepaid by the Company, in whole or in identical part, as the case may be, at 100% of the unpaid principal amount thereof so prepaid.

Without limiting the foregoing, this Bond shall also be deemed to be prepaid by the Company, in whole at any time or in part from time to time, if and to the extent that the Company shall have elected to prepay installments under the Clark County Agreement of like principal amount as the Clark County Bonds that it elects to redeem in accordance with Section 3.01(A) of the Clark County Indenture. Such redemption shall be at the amounts, at the times and in the manner provided in Article III of the Clark County Indenture.

In event of such prepayment of the Clark County Bonds, the Company shall notify Ambac and the Trustee that a like principal amount of this bond shall be deemed to have been prepaid. Ambac shall surrender this bond to the Trustee upon the expiration of the Insurance Agreement.

In case all or substantially all of the electric properties of the Company are sold to or taken through the exercise of the right of eminent domain or the right to purchase by any

-8-

municipal or governmental body or agency and released under the provisions of Article XI of the Indenture, the Company shall call for redemption and redeem all of the Bonds of Series BB then outstanding for 100% of the principal amount thereof.

To the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of Bonds of Series BB may be changed and modified with the consent of the Company and upon the written consent of the holders of at least sixty-six and two-thirds percent (66 2/3%) in principal amount of each series of the Bonds then outstanding and entitled to consent, provided that no such change shall be made (a) which would

without the consent of the holders of all Bonds then outstanding and affected thereby (i) reduce the principal of, or premium, sinking fund, or rate of

interest payable on, the Bonds, (ii) postpone the maturity date fixed for the

payment of the principal of, sinking fund upon, or any installment of interest on, the Bonds, (iii) permit the creation of any lien, not otherwise permitted,

prior to or on a parity with the lien of the Indenture, or (iv) reduce the

percentage of the principal amount of Bonds the consent of the holders of which is required for the authorization of any such change or modification, or (b)

which would modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

In case an event of default, as defined in the Indenture, shall occur and be continuing, the principal of all the Bonds outstanding may be declared and may become due and payable in the manner and with the effect provided in the Indenture.

The Company and the Trustee and any paying agent may deem and treat the person in whose name this Bond shall be registered upon the bond register for the Bonds of the BB Series as the absolute owner of such Bond for the purpose of receiving payment of or on account of the principal of and interest on this Bond and for all other purposes, whether or not this Bond be overdue, and neither the Company nor the Trustee nor any paying agent shall be affected by any notice to the contrary; and all such payments so made to such registered owner or upon his order shall be valid and effectual to satisfy and discharge the liability upon this Bond to the extent of the sum or sums so paid.

Before any transfer of this Bond by the registered holder or his or its legal representative will be recognized or given effect by the Company or the Trustee, the registered holder shall note the amounts of all principal prepayments hereon, and shall notify the Company and the Trustee of the name and address of the transferee and shall afford the Company and the Trustee the opportunity of verifying the notation as to prepayment of principal. By the acceptance hereof the holder of this Bond and each transferee shall be deemed to have agreed to indemnify and hold harmless the Company and the Trustee against all losses, claims, damages or liability arising out of any failure on the part of the holder or of any such transferee to comply with the part of the holder or of any such transferee to comply with the requirements of the preceding sentence.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in any indenture supplemental thereto, or in any Bond or coupon thereby secured, or because of any indebtedness thereby secured, shall be had against any incorporator, or against any past, present or future stockholder, officer, or director, as such, of the Company or any successor corporation, either directly or through the Company or of any successor corporation

-9-

under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise; it being expressly agreed and understood that the Indenture, any indenture supplemental thereto and the obligations thereby secured, are solely corporate obligations, and that no personal liability whatever shall attach to, or be incurred by, such incorporators, stockholders, officers or directors, as such, of the Company or of any successor corporation, or any of them, because of the incurring of the indebtedness thereby authorized, or under or by reason of any of the obligations, covenants or agreements contained in the Indenture or in any indenture supplemental thereto or in any of the Bonds or coupons thereby secured, or implied therefrom.

Each registered owner hereof by his acceptance hereof waives any right to exchange any unpaid portion of this Bond for another Bond under Section 10.01 of the Indenture.

This Bond has not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in contravention of said Act and is not transferable except to a successor to Ambac under the Insurance Agreement.

This bond shall not become or be valid or obligatory for any purpose until the authentication certificate endorsed hereon shall have been signed by the Trustee.

IN WITNESS WHEREOF, Nevada Power Company has caused this bond to be executed in its name and behalf by the manual or facsimile signature of its Treasurer and its corporate seal, or a facsimile thereof, to be affixed or printed hereon and attested by the manual or facsimile signature of its Secretary or one of its Assistant Secretaries.

(which Indenture of Mortgage and Deed of Trust as so amended and supplemented is hereinafter in this Bond called the "Indenture"), executed by the Company to Bankers Trust Company (successor to First Interstate Bank of Nevada, N.A., formerly First National Bank of Nevada, Reno, Nevada) ("Trustee"), as Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the terms and conditions upon which the Bonds of Series CC are and are to be secured and the rights, duties and immunities thereunder of the holders or registered owners thereof, of the Company, and of the Trustee. As provided in the Indenture, said Bonds may be issued in series, for various principal sums, may bear different dates and mature at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided or permitted. The Bonds of Series CC are described in said Twenty-Eighth Supplemental Indenture dated as of July 1, 2001 ("Twenty-Eighth Supplemental Indenture") executed by the Company to Bankers Trust Company, as Trustee, and are issuable as single registered bonds.

Said Indenture, among other things, provides that no bondholder or bondholders may institute any suit, action or proceeding for the collection of this Bond, or claim for interest thereon, or to enforce the lien of said Indenture, if and to the extent that the institution or prosecution thereof or the entry of a judgment or a decree therein would, under applicable law, result in the surrender, impairment, waiver or loss of the lien of said Indenture upon any property subject thereto.

This Bond shall be deemed to be prepaid at any time if and to the extent that (1) the Company shall elect to prepay installments payable under

Section 8.1 of the Clark County Agreement and to cause the Clark County Bonds to be redeemed, in whole or in part, pursuant to Section 3.01(A)(5) of the Clark County Indenture, or (2) subject to Section 11.03 of the Indenture, the

Company shall be obligated to prepay installments payable under Sections 11.03 and 11.07 of the Clark County Agreement and to cause the Clark County Bonds to be redeemed,

-13-

in whole or in part, upon the occurrence of an event specified in Section 3.01(B) of the Clark County Indenture. In any such event this Bond shall be deemed to be prepaid by the Company, in whole or in identical part, as the case may be, at 100% of the unpaid principal amount thereof so prepaid.

Without limiting the foregoing, this Bond shall also be deemed to be prepaid by the Company, in whole at any time or in part from time to time, if and to the extent that the Company shall have elected to prepay installments under the Clark County Agreement of like principal amount as the Clark County Bonds that it elects to redeem in accordance with Section 3.01(A) of the Clark County Indenture. Such redemption shall be at the amounts, at the times and in the manner provided in Article III of the Clark County Indenture.

In event of such prepayment of the Clark County Bonds, the Company shall notify Ambac and the Trustee that a like principal amount of this bond shall be deemed to have been prepaid. Ambac shall surrender this bond to the Trustee upon the expiration of the Insurance Agreement.

In case all or substantially all of the electric properties of the Company are sold to or taken through the exercise of the right of eminent domain or the right to purchase by any municipal or governmental body or agency and released under the provisions of Article XI of the Indenture, the Company shall call for redemption and redeem all of the Bonds of Series CC then outstanding for 100% of the principal amount thereof.

To the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of Bonds of Series CC may be changed and modified with the consent of the Company and upon the written consent of the holders of at least sixty-six and two-thirds percent (66 2/3%) in principal amount of each series of the Bonds then outstanding and entitled to consent, provided that no such change shall be made (a) which would

without the consent of the holders of all Bonds then outstanding and affected thereby (i) reduce the principal of, or premium, sinking fund, or rate of

interest payable on, the Bonds, (ii) postpone the maturity date fixed for the

payment of the principal of, sinking fund upon, or any installment of interest on, the Bonds, (iii) permit the creation of any lien, not otherwise permitted,

prior to or on a parity with the lien of the Indenture, or (iv) reduce the

percentage of the principal amount of Bonds the consent of the holders of which is required for the authorization of any such change or modification, or (b)

which would modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

In case an event of default, as defined in the Indenture, shall occur and be continuing, the principal of all the Bonds outstanding may be declared and may become due and payable in the manner and with the effect provided in the Indenture.

The Company and the Trustee and any paying agent may deem and treat the person in whose name this Bond shall be registered upon the bond register for the Bonds of the CC Series as the absolute owner of such Bond for the purpose of receiving payment of or on account of the principal of and interest on this Bond and for all other purposes, whether or not this Bond be overdue, and neither the Company nor the Trustee nor any paying agent shall be affected by any notice to the contrary; and all such payments so made to such registered owner or upon his order

-14-

shall be valid and effectual to satisfy and discharge the liability upon this Bond to the extent of the sum or sums so paid.

Before any transfer of this Bond by the registered holder or his or its legal representative will be recognized or given effect by the Company or the Trustee, the registered holder shall note the amounts of all principal prepayments hereon, and shall notify the Company and the Trustee of the name and address of the transferee and shall afford the Company and the Trustee the opportunity of verifying the notation as to prepayment of principal. By the acceptance hereof the holder of this Bond and each transferee shall be deemed to have agreed to indemnify and hold harmless the Company and the Trustee against all losses, claims, damages or liability arising out of any failure on the part of the holder or of any such transferee to comply with the part of the holder or of any such transferee to comply with the requirements of the preceding sentence.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in any indenture supplemental thereto, or in any Bond or coupon thereby secured, or because of any indebtedness thereby secured, shall be had against any incorporator, or against any past, present or future stockholder, officer, or director, as such, of the Company or any successor corporation, either directly or through the Company or of any successor corporation under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise; it being expressly agreed and understood that the Indenture, any indenture supplemental thereto and the obligations thereby secured, are solely corporate obligations, and that no personal liability whatever shall attach to, or be incurred by, such incorporators, stockholders, officers or directors, as such, of the Company or of any successor corporation, or any of them, because of the incurring of the indebtedness thereby authorized, or under or by reason of any of the obligations, covenants or agreements contained in the Indenture or in any indenture supplemental thereto or in any of the Bonds or coupons thereby secured, or implied therefrom.

Each registered owner hereof by his acceptance hereof waives any right to exchange any unpaid portion of this Bond for another Bond under Section 10.01 of the Indenture.

This Bond has not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in contravention of said Act and is not transferable except to a successor to Ambac under the Insurance Agreement.

This bond shall not become or be valid or obligatory for any purpose until the authentication certificate endorsed hereon shall have been signed by the Trustee.

IN WITNESS WHEREOF, Nevada Power Company has caused this bond to be executed in its name and behalf by the manual or facsimile signature of its Treasurer and its corporate seal, or a facsimile thereof, to be affixed or printed hereon and attested by the manual or facsimile signature of its Secretary or one of its Assistant Secretaries.

ARTICLE I
DEFINITIONS; CONSTRUCTION

SECTION 1.01 Defined Terms.

As used in this Agreement, the following terms have the following meanings:

"ABR", when used in reference to any Loan or Borrowing, refers

to whether such Loan, or the Loans comprising such Borrowing, are bearing interest at a rate determined by reference to the Alternate Base Rate.

"Acceptable NPC Rate Case" has the meaning assigned to the term "Acceptable Rate Case" in Section 1.01 of the NPC Credit Agreement.

"Acceptable SPPC Rate Case" has the meaning assigned to the term "Acceptable Rate Case" in Section 1.01 of the SPPC Credit Agreement.

"Acquisition" means any transaction, or any series of related transactions, consummated after the Effective Date, by which the Borrower and/or any of its Subsidiaries directly or indirectly (a) acquires any ongoing business or all or substantially all of the assets of any Person engaged in any ongoing business, whether through purchase of assets, merger or otherwise, (b) acquires control of securities of a Person engaged in an ongoing business representing more than 50% of the ordinary voting power for the election of directors or other governing position if the business affairs of such Person are managed by a board of directors or other governing body or (c) acquires control of more than 50% of the ownership interest in any partnership, joint venture, limited liability company, business trust or other Person engaged in an ongoing business that is not managed by a board of directors or other governing body.

"Adjusted LIBO Rate" means, with respect to any Eurodollar Revolving Borrowing for any Interest Period, an interest rate per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

"Administrative Agent" means Union Bank of California, N.A., in its capacity as administrative agent for the Lenders hereunder and any successor appointed pursuant to Section 8.10.

"Affiliate" means any Person that directly or indirectly Controls, or is under common Control with, or is Controlled by, another Person, provided that, in any event, any Person that owns directly or indirectly securities having 20% or more of the voting power for the election of directors or other governing body of a corporation or 20% or more of the partnership or other ownership interests of any other Person (other than as a limited partner of such other Person) will be deemed to Control such corporation or other Person.

"Agents" means, collectively, the Administrative Agent, the Co-Lead Arrangers, the Sole Bookrunner, the Syndication Agent and the Co-Documentation Agents.

"Alternate Base Rate" means, for any day, a rate per annum equal to the greater of (a) the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%.

"Applicable Percentage" means, with respect to any Lender as of any date of determination, the percentage of the total Commitments as of such date represented by such Lender's Commitment as of such date. If the Commitments have terminated or expired, the Applicable Percentages shall be determined, as of any date of determination, based upon the percentage of the total Loans outstanding as of such date represented by such Lender's Loans outstanding as of such date.

"Applicable Rate" means, for any day, with respect to the facility fees payable hereunder or with respect to any Eurodollar Revolving Loan or ABR Loan, as the case may be, the applicable rate per annum set forth opposite the caption "Facility Fee", "Eurodollar Spread" or "ABR Spread", as the case may be, in the applicable pricing table set forth below, based on the ratings by S&P and Moody's applicable on such day to the Index Debt of Borrower:

(v) the location and number of the Borrower's account to which funds are to be disbursed, which shall comply with the requirements of Section 2.04.

If no election as to the Type of Revolving Borrowing is specified, then the requested Revolving Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any Eurodollar Revolving Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month's duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of

-17-

the details thereof and of the amount of such Lender's Loan to be made as part of the requested Borrowing.

SECTION 2.04 Funding of Borrowings.

(a) Funding by Lenders. No later than 12:00 noon, New York, New York time, on the date specified in each Borrowing Request, each Lender will make available its Applicable Percentage of each Revolving Borrowing requested to be made on such date, in Dollars and in immediately available funds at the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with Union Bank of California, N.A. at the Principal Office and designated by the Borrower in the applicable Borrowing Request.

(b) Presumption by the Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the Federal Funds Effective Rate or (ii) in the case of the Borrower, the interest rate applicable to the Loans of such Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing.

SECTION 2.05 Interest Elections.

(a) Elections by the Borrower for Borrowings. Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section but subject to Section 2.02. Once Loans have been made pursuant to a Borrowing, the Borrower may elect to convert or continue different portions of such Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) Notice of Elections. To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

-18-

(c) Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) of this paragraph shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing, or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration.

(d) Notice by the Administrative Agent to Lenders. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing.

(e) Failure to Elect; Events of Default. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.06 Termination, Reduction and Extension of Commitments.

(a) Scheduled Termination. Unless previously terminated, the Commitments shall terminate on the Revolving Termination Date.

(b) Voluntary Termination or Reduction. The Borrower may at any time prior to the Revolving Termination Date terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount of $10,000,000 or a multiple of $1,000,000 in excess thereof and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance

-19-

with Section 2.08, the sum of the total Revolving Credit Exposures would exceed the total Commitments.

(c) Notice of Voluntary Termination or Reduction. The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this
Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

(d) Effect of Termination or Reduction. Any termination or reduction of the Commitments shall be permanent. Except as otherwise provided in
Section 2.06(e)(i), each reduction of the Commitments shall be made ratably among the Lenders in accordance with their Applicable Percentages.

(e) Extension of Commitments.

(i) Not earlier than the date which is 60 days (but not later than 30 days) prior to the then existing Revolving Termination Date (the "Extension Request Notice Date"), the Borrower may deliver to the Administrative Agent (which shall promptly transmit the same to each Lender) a notice (an "Extension Request") requesting that the Revolving Termination Date be extended for an additional 364 days commencing on the then existing Revolving Termination Date. Not earlier than the date which is 30 days (but not later than 20 days) prior to the then existing Revolving Termination Date (the period from the Extension Request Notice Date to such date, the "Extension Request Period"), each Lender (in its sole and absolute discretion and after conducting an internal credit review of the Borrower) shall notify the Administrative Agent of such Lender's willingness or unwillingness to so extend the Revolving Termination Date. Any Lender which shall fail to so notify the Administrative Agent within such period shall be deemed to have declined to extend the Revolving Termination Date. If Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect agree to such extension by notice to the Administrative Agent, then (A) subject to clause (iii) below, the Revolving Termination Date shall be extended for an additional 364 days with respect to the Commitments of the Lenders so agreeing, and (B) subject to Section 2.06(f) hereof, the Commitment of each Lender not so agreeing shall expire on the then expiring Revolving Termination Date and the Borrower shall pay or prepay on such day without premium or penalty all principal of such Lender's Loans together with accrued interest thereon and all accrued facility fees and other amounts payable to such Lender hereunder (including, without limitation, amounts payable pursuant to Section 2.13 hereof as a result of such payment or prepayment); provided, however, that

(x) if Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect do not agree as contemplated by
Section 2.06(e)(i), then the Revolving Termination Date shall not be extended pursuant to this Section 2.06(e) and the Commitments of all

-20-

of the Lenders shall remain in effect until the Revolving Termination Date except as otherwise provided in this Agreement; and

(y) the Borrower may not request any extension of the Revolving Termination Date pursuant to this Section 2.06(e)(i) more frequently than once in any calendar year.

(ii) Any Loan by any Lender the Commitment of which is to terminate pursuant to Section 2.06(e)(i) hereof that would otherwise be made or converted by such Lender as a Eurodollar Loan having an Interest Period ending after the date such Commitment is to terminate shall be made or continued as an ABR Loan and all ABR Loans of such Lender that would otherwise be converted into Eurodollar Loans having such Interest Periods shall remain as ABR Loans.

(iii) It shall be a condition precedent to any extension of the Revolving Termination Date that: (a) on the date of such extension no Default or Event of Default shall have occurred and be continuing;
(b) the representations and warranties made by the Borrower in Article III shall be true and correct on and as of the date of such extension (or if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and (c) on the date of such extension there shall have been no material adverse change in the consolidated financial condition, operations, business or prospects taken as a whole of the Borrower and its Subsidiaries from that set forth in its financial statements as of September 30, 2001 referred to in Section 3.06 hereof or, if the Borrower has delivered its financial statements for any fiscal year to the Lenders and the Administrative Agent pursuant to Section 5.01(a) hereof, as of the date of the most recent such financial statements. Each request for an extension of the Revolving Termination Date pursuant to Section 2.06(e) shall constitute a certification by the Borrower to the effect set forth in the preceding sentence (both as of the date of such request and, unless the Borrower notifies the Administrative Agent prior to the date of such extension, as of the date of such extension).

(f) Substitute Lenders. In the event any Lender does not agree to any extension by the date provided pursuant to Section 2.06(e) hereof, then, unless a Default or an Event of Default shall have occurred and be continuing, the Borrower may, not later than 10 days following the expiration of the Extension Request Period, designate one or more other banks (each such bank being herein called a "Substitute Lender"), which may include any of the Lenders, acceptable to the Administrative Agent (which acceptance will not be unreasonably withheld), to assume such non-consenting Lender's Commitment hereunder and to purchase, on or before the date such Lender's Loans would otherwise be required to be paid or prepaid hereunder, the Loans and Notes of such Lender and such Lender's rights hereunder in respect thereof, without recourse to or representation or warranty by, or expense to, such Lender. In such event, the purchase price shall be equal to the outstanding principal amount of the Loans and Notes payable to such Lender plus any accrued but unpaid interest on such Loans and Notes and accrued but unpaid facility fees in respect of such Lender's Commitment. Upon such assumption and purchase and the receipt by such Lender of any other amounts payable to it by the Borrower under this Agreement, and subject to the execution and delivery to the Administrative Agent and such Lender by the Substitute Lender of documentation reasonably satisfactory to the Administrative Agent and such Lender pursuant to which such Substitute Lender shall assume the obligations of such original Lender under this Agreement in respect of its Loans, Notes and Commitment and agree to become a "Lender" hereunder (if not already a

-21-

Lender) to the extent of the Commitments, Loans and Notes assumed and purchased, the Substitute Lender shall succeed to the rights, obligations and benefits of such Lender hereunder in such respect (except for such rights, obligations and benefits of the Lender as have accrued (other than principal, accrued interest or facility fees) or are required to be performed by it on or prior to the date of such assumption and purchase) (and such Lender shall be released from its Commitment except for any liability arising or relating to any event occurring prior to the date of such assumption and purchase) and the Substitute Lender shall be deemed to have agreed to the relevant extension of the Revolving Termination Date and, anything in Section 2.06(e) to the contrary notwithstanding, whether such extension is effective shall be determined accordingly; provided that following any such assumption and purchase the Commitments of each Substitute Lender (including any Commitments theretofore held by it) shall be not less than $10,000,000.

SECTION 2.07 Repayment of Loans; Evidence of Debt.

(a) Repayment. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of the Lenders the outstanding principal amount of the Revolving Loans on the Revolving Termination Date.

(b) Manner of Payment. Prior to any repayment or prepayment of any Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings to be paid and shall notify the Administrative Agent by telephone (confirmed by telecopy) of such selection not later than 12:00 noon, New York, New York time, three Business Days before the scheduled date of such repayment or prepayment; provided that each repayment or prepayment of Borrowings shall be applied to repay or prepay any outstanding ABR Borrowings before any other Borrowings. If the Borrower fails to make a timely selection of the Borrowing or Borrowings to be repaid or prepaid, such payment shall be applied, first, to pay any outstanding ABR Borrowings and, second, to other Borrowings in the order of the remaining duration of their respective Interest Periods (the Borrowing with the shortest remaining Interest Period to be repaid first). Each payment of a Revolving Borrowing shall be applied ratably to the Loans included in such Borrowing.

(c) Maintenance of Loan Accounts by Lenders. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(d) Maintenance of Loan Accounts by the Administrative Agent.
The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder and the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

(e) Effect of Entries. The entries made in the accounts maintained pursuant to paragraphs (c) and (d) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

-22-

(f) Notes. Any Lender may request that Loans made by it be evidenced by a promissory note (each a "Note") in substantially the form of

Exhibit C. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in the form of Exhibit C. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 9.12) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

SECTION 2.08 Prepayment of Loans.

(a) Optional Prepayments Right to Prepay Borrowings. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section.

(b) Notices, Etc. The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any optional prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York, New York time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York, New York time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by
Section 2.06(c), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(c). Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an aggregate principal amount equal to $3,000,000 and a multiple of $1,000,000 in excess thereof; provided that if any prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Revolving Loans made pursuant to such Borrowing to an amount less than $3,000,000, such outstanding Loans shall immediately be converted into ABR Loans. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.10 and shall be made in the manner specified in this Section 2.08(b).

SECTION 2.09 Fees.

(a) Facility Fee. The Borrower shall pay the Administrative Agent for the account of each Lender a facility fee for the period from and including the Effective Date to but excluding the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated) computed at a rate per annum equal to the Applicable Rate on each Lender's daily average Commitment, such fee to be paid quarterly in arrears on each Quarterly Date and on the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated). The facility fee shall be calculated on the basis of the actual number of days elapsed in a year of 360 days.

(b) Fee Letter. The Borrower agrees to pay to the Administrative Agent, for the account of the Administrative Agent and the Co-Lead Arrangers, the fees agreed to by the Borrower, NPC, SPPC, the Administrative Agent and the Co-Lead Arrangers pursuant to that

-23-

certain letter agreement, dated the date hereof (the "Fee Letter"), or as otherwise agreed from time to time.

(c) Payment of Fees. All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of facility fees, to the Lenders entitled thereto.

SECTION 2.10 Interest.

(a) ABR Loans. The Loans comprising each ABR Revolving Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate.

(b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Default Interest. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% above the higher of (A) the rate otherwise applicable to such Loan as provided above and (B) the rate applicable to ABR Loans as provided in paragraph (a) of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d) Payment of Interest. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (x) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (y) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the Revolving Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (z) in the event of any conversion of any Eurodollar Borrowing prior to the end of the current Interest Period therefor, accrued interest on such Borrowing shall be payable on the effective date of such conversion.

(e) Computation. All interest hereunder shall be computed on the basis of a year of 360 days, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive, absent manifest error.

SECTION 2.11 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately

-24-

and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Revolving Borrowing.

SECTION 2.12 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or its Parent (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or its Parent or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender or its Parent of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of its Parent as a consequence of this Agreement or the Loans made by such Lender to a level below that which such Lender or its Parent could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of its Parent with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent for any such reduction suffered.

(c) Certificates from Lenders. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its Parent, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation.

-25-

SECTION 2.13 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable under Section 2.08(b) and is revoked in accordance herewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to
Section 2.16, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an Affiliate of such Lender) for dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.14 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, each Co-Lead Arranger, the Syndication Agent or each Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable Law.

(b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Co-Lead Arranger, the Syndication Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Co-Lead Arranger, the Syndication Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified

-26-

Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, a Co-Lead Arranger, the Syndication Agent or the Administrative Agent (on its own behalf or on behalf of a Lender, a Co-Lead Arranger or the Syndication Agent) shall be conclusive, absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable Law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without withholding or at a reduced rate.

SECTION 2.15 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.12, 2.13 or 2.14, or otherwise) prior to 1:00 PM, New York, New York time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any such date shall be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its Principal Office and to such account at its Principal Office as the Administrative Agent shall specify to the Borrower, except that payments pursuant to Sections 2.12, 2.13, 2.14 and 9.04 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Revolving Borrowing shall be made from the Lenders, each payment of facility fees under Section 2.09 shall be made for the account of the Lenders, and each termination or reduction of the amount of the Commitments under Section 2.06 shall be applied to the respective

-27-

Commitments of the Lenders, pro rata according to the amounts of their respective Commitments; (ii) each Borrowing shall be allocated pro rata among the Lenders according to the amounts of their respective Commitments (in the case of the making of Revolving Loans) or their respective Loans (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders.

(d) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon then due than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(e) Presumptions of Payment. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate.

(f) Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or 2.15(e), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.16 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.12), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

In the absence of such directions, the Administrative Agent shall have the authority (but under no circumstances shall be obligated), in its sole discretion, to take any such action, except to the extent that this Agreement or such other Loan Document expressly requires the direction or consent of the Required Lenders (or some other Person or set of Persons), in which case the Administrative Agent shall not take such action absent such direction or consent.

-55-

the Administrative Agent in its individual capacity as such. The Administrative Agent and its affiliates may, without liability to account, make loans to, accept deposits from, acquire debt or equity interests in, act as trustee under indentures of, and engage in any other business with, the Borrower and any stockholder, subsidiary or affiliate of the Borrower, as though the Administrative Agent were not the Administrative Agent hereunder.

SECTION 8.09 Holders of Notes.

The Administrative Agent may deem and treat the Lender which is payee of a Note as the owner and holder of such Note for all purposes hereof unless and until an Assignment and Acceptance with respect to the assignment or transfer thereof shall have been filed with the Administrative Agent in accordance with Section 9.12. Any authority, direction or consent of any Person who at the time of giving such authority, direction or consent is shown in the Register as being a Lender shall be conclusive and binding on each present and subsequent holder, transferee or assignee of any Note or Notes payable to such Lender or of any Note or Notes issued in exchange therefor.

Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed and consented to, and shall have accepted such appointment, within 30 days after such notice of resignation or removal, then the retiring Administrative Agent, on behalf of the Lenders, may appoint a successor Administrative Agent. Each successor Administrative Agent shall be a commercial bank or trust company organized under the Laws of the United States of America or any State thereof and having a combined capital and surplus of at least $1,000,000,000. The appointment of any successor Administrative Agent at any time pursuant to this Section 8.10 shall be subject to the approval of the Borrower, provided that at such time there shall not have occurred and be continuing any Default or Event of Default, and provided further that the Borrower's consent to any such appointment shall not be unreasonably withheld. Upon the acceptance by a successor Administrative Agent of its appointment as Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the properties, rights, powers, privileges and duties of the former Administrative Agent without further act, deed or conveyance. Upon the effective date of resignation or removal of a retiring Administrative Agent, the Administrative Agent shall be discharged from its duties under this Agreement and the other Loan Documents, but the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted by it while it was Administrative Agent under this Agreement. If and for so long as no successor Administrative Agent shall have been appointed, then any notice or other communication required or permitted to be given by the Administrative Agent shall be sufficiently given if given by the Required Lenders, all notices or other communications required or permitted to be given to the Administrative Agent shall be given to each Lender, and all payments to be made to the Administrative Agent shall be made directly to the Borrower or Lender for whose account such payment is made.

The parties hereto intend to conform to all applicable Laws in effect from time to time limiting the maximum rate of interest that may be charged or collected. Accordingly, notwithstanding any other provision hereof or of any other Loan Document, the Borrower shall not be required to make any payment to or for the account of any Lender, and each Lender shall refund any payment made by the Borrower, to the extent that such requirement or such failure to

-61-

refund would violate or conflict with nonwaivable provisions of applicable Laws limiting the maximum amount of interest which may be charged or collected by such Lender.

SECTION 9.10 Set-Off.

The Borrower hereby agrees that, to the fullest extent permitted by Law, if any Obligation of the Borrower shall be due and payable (by acceleration or otherwise), each Lender shall have the right, without notice to the Borrower, to set-off against and to appropriate and apply to such Obligation any indebtedness, liability or obligation of any nature owing to the Borrower by such Lender, including but not limited to all deposits (whether time or demand, general or special, provisionally credited or finally credited, whether or not evidenced by a certificate of deposit) now or hereafter maintained by the Borrower with such Lender. Such right shall be absolute and unconditional in all circumstances and, without limitation shall exist whether or not such Lender or any other Person shall have given notice or made a demand to the Borrower or any other Person, whether such indebtedness, obligation or liability owed to the Borrower is contingent, absolute, matured or unmatured (it being agreed that such Lender may deem such indebtedness, obligation or liability to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty or any other security, right or remedy available to any Lender or any other Person. The Borrower hereby agrees that, to the fullest extent permitted by Law, any Participant and any branch, subsidiary or affiliate of any Lender or any Participant shall have the same rights of set-off as a Lender as provided in this Section (regardless of whether such Participant, branch, subsidiary or affiliate would otherwise be deemed in privity with or a direct creditor of the Borrower).

Section are in addition to all other rights of set-off and banker's lien and all other rights and remedies which any Lender (or any such Participant, branch, subsidiary or affiliate) may otherwise have under this Agreement, any other Loan Document, at law or in equity, or otherwise, and nothing in this Agreement or any other Loan Document shall be deemed a waiver or prohibition of or restriction on the rights of set-off or bankers' lien of any such Person.

SECTION 9.11 Sharing of Collections.

The Lenders hereby agree among themselves that if any Lender shall receive (by voluntary payment, realization upon security, set-off or from any other source) any amount on account of the Loans, interest thereon, or any other Obligation contemplated by this Agreement or the other Loan Documents to be made by the Borrower pro rata to all Lenders (or pro rata to holders of Notes) in greater proportion than any such amount received by any other applicable Lender, then the Lender receiving such proportionately greater payment shall notify each other Lender and the Administrative Agent of such receipt, and equitable adjustment will be made in the manner stated in this
Section 9.11 so that, in effect, all such excess amounts will be shared ratably among all of the applicable Lenders. The Lender receiving such excess amount shall purchase (which it shall be deemed to have done simultaneously upon the receipt of such excess amount) for cash from the other applicable Lenders a participation in the applicable Obligations owed to such other Lenders in such amount as shall result in a ratable sharing by all applicable Lenders of such excess amount (and to such extent the receiving Lender shall be a Participant). If all or any portion of such excess amount is thereafter recovered from the Lender making such purchase, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by Law to be paid by the Lender making such purchase. The Borrower hereby consents to and confirms the foregoing

-62-

arrangements. Each Participant shall be bound by this Section as fully as if it were a Lender hereunder.

SECTION 9.12 Successors and Assigns; Participations; Assignments.

(a) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, all future holders of the Notes, the Agents and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights hereunder or interests herein without the prior written consent of all the Lenders and the Administrative Agent, and any purported assignment without such consent shall be void.

(b) Participations. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time sell participations to one or more commercial banks or other Persons (each a "Participant") in all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of its Commitment and the Loans owing to it and any Note held by it); provided, that

(i) any such Lender's obligations under this Agreement and the other Loan Documents shall remain unchanged,

(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,

(iii) the parties hereto shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and each of the other Loan Documents,

(iv) such Participant shall be bound by the provisions of
Section 9.11, and

(v) no Participant (unless such Participant is an Affiliate of such Lender, or is itself a Lender) shall be entitled to require such Lender to take or refrain from taking action under this Agreement or under any other Loan Document, except that such Lender may agree with such Participant that such Lender will not, without such Participant's consent, take any action, or consent to the taking of any action, of the type described in Section 9.01(a), (b) or (c).

The Borrower agrees that any such Participant shall be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.04 with respect to its participation in the Commitments and the Loans outstanding from time to time; provided, that no such Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred to such Participant had no such transfer occurred.

(c) Assignments. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time assign all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or any portion of its Commitment and Loans owing to it and any Note held by it) to any Lender, any Affiliate of a Lender or to one or more additional commercial banks or other Persons (each a "Purchasing Lender"); provided, that

-63-

(i) any such assignment to a Purchasing Lender which is not a Lender or an affiliate of a Lender shall be made only with the consent (which in each case shall not be unreasonably withheld) of the Borrower (so long as no Default or Event of Default shall have occurred and be continuing) and the Administrative Agent;

(ii) if a Lender makes such an assignment of less than all of its then remaining rights and obligations under this Agreement and the other Loan Documents, such transferor Lender shall retain, after such assignment, a minimum principal amount of $5,000,000 of the Commitments and Loans then outstanding, and such assignment, unless made to an assignee who is a Lender hereunder prior to such assignment, shall be in a minimum principal amount of $5,000,000 of the Commitments and Loans then outstanding;

(iii) each such assignment shall be of a constant, and not a varying, percentage of the Commitment of the transferor Lender and of all of the transferor Lender's rights and obligations under this Agreement and the other Loan Documents; and

(iv) each such assignment shall be made pursuant to an Assignment and Acceptance.

In order to effect any such assignment, the transferor Lender and the Purchasing Lender shall execute and deliver to the Administrative Agent a duly completed Assignment and Acceptance (including the consents required by clause (i) of the preceding sentence) with respect to such assignment, together with any Note or Notes subject to such assignment and a processing and recording fee of $3,500; and, upon receipt thereof, the Administrative Agent shall accept such Assignment and Acceptance. Upon receipt of notice from the transferor Lender that it has received the consideration described in the Assignment and Acceptance, the Administrative Agent shall record such acceptance in the Register. Upon such execution, delivery, acceptance and recording, from and after the close of business at the Administrative Agent's Principal Office on the settlement date specified in such Assignment and Acceptance:

(x) the Purchasing Lender shall be a party hereto and, to the extent provided in such Assignment and Acceptance, shall have the rights and obligations of a Lender hereunder, and

(y) the transferor Lender thereunder shall be released from its obligations under this Agreement to the extent so transferred (and, in the case of an Assignment and Acceptance covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party to this Agreement) from and after the settlement date.

On or prior to the settlement date specified in an Assignment and Acceptance, the Borrower, at its expense, shall execute and deliver to the Administrative Agent (for delivery to the Purchasing Lender) new Notes evidencing such Purchasing Lender's assigned Commitment or Loans and (for delivery to the transferor Lender) replacement Notes in the principal amount of the Loans or Commitment retained by the transferor Lender (such Notes to be in exchange for, but not in payment of, those Notes then held by such transferor Lender). Each such Note shall be dated the date and be substantially in the form of the predecessor Note. The Administrative Agent shall mark the predecessor Notes "exchanged" and deliver them to the Borrower. Accrued interest

-64-

and accrued fees shall be paid to the Purchasing Lender at the same time or times provided in the predecessor Notes and this Agreement.

(d) Register. The Administrative Agent shall maintain at its office a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive absent manifest error and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of the Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Financial and Other Information. The Borrower authorizes the Administrative Agent and each Lender to disclose to any Participant or Purchasing Lender (each, a "transferee") and any prospective transferee any and all financial and other information in such Person's possession concerning the Borrower and its Subsidiaries and Affiliates which has been or may be delivered to such Person by or on behalf of the Borrower in connection with this Agreement or any other Loan Document or such Person's credit evaluation of the Borrower and its Subsidiaries and Affiliates.

(f) Assignments to Federal Reserve Bank. Any Lender may at any time assign all or any portion of its rights under this Agreement, including without limitation any Loans owing to it, and any Note held by it, to a Federal Reserve Bank. No such assignment shall relieve the transferor Lender from its obligations hereunder.

(g) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC") the option to fund all or

any part of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to the terms hereof. The funding of a Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the Granting Lender to the same extent, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. Notwithstanding anything to the contrary contained in this Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. 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.

(iv) WAIVES THE RIGHT TO TRIAL BY JURY IN ANY RELATED LITIGATION.

(c) Limitation of Liability.

-66-

LIABILITY). EACH PARTY TO THIS AGREEMENT HEREBY WAIVES, RELEASES AND AGREES NOT TO SUE UPON ANY CLAIM FOR ANY SUCH DAMAGES, WHETHER SUCH CLAIM PRESENTLY EXISTS OR ARISES HEREAFTER AND WHETHER OR NOT SUCH CLAIM IS KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.

EXHIBIT 10(B)

CHANGE IN CONTROL AGREEMENT -- CEO

THIS AGREEMENT, dated May 21, 2001, is made by and between Sierra Pacific Resources, a Nevada corporation (the "Company"), and Walter M. Higgins (the "Executive").

WHEREAS, the Company considers it essential to the best interests of its stockholders to foster the continued employment of key management personnel; and

WHEREAS, the Board recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders; and

WHEREAS, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the management of the Company and its subsidiaries (collectively, "Sierra"), including the Executive, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a Change in Control;

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as follows:

1. Defined Terms. The definitions of capitalized terms used in this Agreement are provided in the last Section hereof.

2. Term of Agreement. Subject to the provisions of Section 12.2 hereof, the term of this Agreement shall commence on the date hereof and shall continue in effect through December 31, 2004; provided, however, that if a Change in Control shall have occurred during the Term, the Term shall expire no earlier than twenty-four (24) months beyond the month in which such Change in Control occurred; and further provided, however, that if a Potential Change in Control shall have occurred during the Term, the Term shall expire no earlier than the latter of (a) the date on which such potential Change in Control shall have been terminated, or (b) 24 months beyond the date on which such potential Change in Control shall have resulted in a Change of Control.

1

3. Company's Covenants Summarized. In order to induce the Executive to remain in the employ of Sierra and in consideration of the Executive's covenants set forth in Section 4 hereof, the Company agrees, under the conditions described herein, to pay the Executive the Severance Payments and the other payments and benefits described herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be payable under this Agreement unless there shall have been (or, under the terms of the second sentence of Section 6.1 hereof, there shall be deemed to have been) a termination of the Executive's employment with Sierra following a Change in Control or potential Change in Control and during the Term. This Agreement shall not be construed as creating an express or implied contract of employment and, except as otherwise agreed in writing between the Executive and Sierra, the Executive shall not have any right to be retained in the employ of Sierra. The obligations of the Company hereunder shall be deemed satisfied to the extent payments are made by Sierra Pacific Power, Nevada Power, or any affiliate of the Company.

4. The Executive's Covenants. The Executive agrees that, subject to the terms and conditions of this Agreement, in the event of a Potential Change in Control during the Term, the Executive will remain in the employ of the Company until the earliest of (i) a date which is six (6) months from the date of such Potential Change of Control, (ii) the date of a Change in Control, (iii) the date of termination by the Executive of the Executive's employment for Good Reason or by reason of death, Disability or Retirement, or
(iv) the termination by Sierra of the Executive's employment for any reason.

5. Compensation Other Than Severance Payments.

5.1 Following a Change in Control or potential Change in Control and during the Term, during any period that the Executive fails to perform the Executive's full-time duties with Sierra as a result of incapacity due to physical or mental illness, the Company shall pay the Executive's full salary to the Executive at the rate in effect at the commencement of any such period, together with all compensation and benefits payable to the Executive under the terms of any compensation or benefit plan, program or arrangement maintained by Sierra during such period, until the Executive's employment is terminated by Sierra for Disability.

5.2 If the Executive's employment shall be terminated for any reason following a Change in Control or potential Change in Control and during the Term, the Company shall pay the Executive's full salary to the Executive through the Date of Termination at the rate in effect immediately prior to the Date of Termination or, if higher, the rate in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, together with all compensation and benefits payable to the Executive through the Date of Termination under the terms of Sierra compensation and benefit plans, programs or arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive,

2

as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

5.3 If the Executive's employment shall be terminated for any reason following a Change in Control or potential Change in Control and during the Term, the Company shall pay to the Executive the Executive's normal post-termination compensation and benefits as such payments become due. Such post-termination compensation and benefits shall be determined under, and paid in accordance with, Sierra's retirement, insurance and other compensation or benefit plans, programs and arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the occurrence of the first event or circumstance constituting Good Reason.

6. Severance Payments.

6.1 Subject to Section 6.2 hereof, if the Executive's employment is terminated following a Change in Control and during the Term, other than (A) by Sierra for Cause, (B) by reason of death or Disability, or (C) by the Executive without Good Reason, then Sierra shall pay the Executive the amounts, and provide the Executive the benefits, described in this Section 6.1 ("Severance Payments"), in addition to any payments and benefits to which the Executive is entitled under Section 5 hereof. For purposes of this Agreement, the Executive's employment shall be deemed to have been terminated following a Change in Control by Sierra without Cause or by the Executive with Good Reason, if (i) the Executive's employment is terminated by Sierra without Cause prior to a Change in Control (whether or not a Change in Control ever occurs) and such termination was at the request or direction of a Person who has entered into an agreement with the Company the consummation of which would constitute a Change in Control, (ii) the Executive terminates his employment for Good Reason prior to a Change in Control (whether or not a Change in Control ever occurs) and the circumstance or event which constitutes Good Reason occurs at the request or direction of such Person, or (iii) the Executive's employment is terminated by Sierra without Cause or by the Executive for Good Reason and such termination or the circumstance or event which constitutes Good Reason is otherwise in connection with or in anticipation of a Change in Control (whether or not a Change in Control ever occurs). For purposes of any determination regarding the applicability of the immediately preceding sentence, any position taken by the Executive shall be presumed to be correct unless the Company establishes to the Board by clear and convincing evidence that such position is not correct.

(A) In lieu of any further salary payments to the Executive for periods subsequent to the Date of Termination and in lieu of any severance benefit otherwise payable to the Executive under or pursuant to any contract or plan, except for any severance benefits relating to or resulting from the Supplemental Executive Retirement Plan, whether as a consequence of a Change in Control or otherwise, the Company shall pay to the Executive a

3

lump sum severance payment, in cash, equal to three times the sum of
(i) the Executive's base salary as in effect immediately prior to the Date of Termination or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, and (ii) the target annual incentive award applicable to the Executive pursuant to any annual bonus or incentive plan maintained by Sierra in respect of the fiscal year ending immediately prior to the fiscal year in which occurs the Date of Termination or, if higher, immediately prior to the fiscal year in which occurs the first event or circumstance constituting Good Reason.

(B) For the thirty-six (36) month period immediately following the Date of Termination, the Company shall arrange to provide the Executive and his dependents life, disability, accident and health insurance benefits substantially similar to those provided to the Executive and his dependents immediately prior to the Date of Termination or, if more favorable to the Executive, those provided to the Executive and his dependents immediately prior to the first occurrence of an event or circumstance constituting Good Reason, at no greater cost to the Executive than the cost to the Executive immediately prior to such date or occurrence; provided, however, that, unless the Executive consents to a different method (after taking into account the effect of such method on the calculation of "parachute payments" pursuant to Section 6.2 hereof), such health insurance benefits shall be provided through a third-party insurer. Benefits otherwise receivable by the Executive pursuant to this Section 6.1(B) shall be reduced to the extent benefits of the same type are received by or made available to the Executive during the thirty-six (36) month period following the Executive's termination of employment (and any such benefits received by or made available to the Executive shall be reported to the Company by the Executive); provided, however, that the Company shall reimburse the Executive for the excess, if any, of the cost of such benefits to the Executive over such cost immediately prior to the Date of Termination or, if more favorable to the Executive, the first occurrence of an event or circumstance constituting Good Reason. If the Severance Payments shall be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B) benefits which remain payable after the application of Section 6.2 hereof are thereafter reduced pursuant to the immediately preceding sentence, the Company shall, no later than five (5) business days following such reduction, pay to the Executive the least of (a) the amount of the decrease made in the Severance Payments pursuant to Section 6.2 hereof, (b) the amount of the subsequent reduction in these Section 6.1(B) benefits, or (c) the maximum amount which can be paid to the Executive without being, or causing any other payment to be, nondeductible by reason of Section 280G of the Code.

(C) Notwithstanding any provision of any annual or long-term incentive plan to the contrary, the Company shall pay to the Executive a lump sum amount, in cash, equal to the sum of (i) any unpaid incentive

4

compensation which has been allocated or awarded to the Executive fora completed fiscal year or other measuring period preceding the Date of Termination under any such plan and which, as of the Date of Termination, is contingent only upon the continued employment of the Executive to a subsequent date, and (ii) a pro rata portion to the Date of Termination of the aggregate value of all contingent incentive compensation awards to the Executive for all then uncompleted periods under any such plan, calculated as to each such award by multiplying the award that the Executive would have earned on the last day of the performance award period, assuming the achievement, at the target level of the individual and corporate performance goals established with respect to such award, by the fraction obtained by dividing the number of full months and any fractional portion of a month during such performance award period through the Date of Termination by the total number of months contained in such performance award period.

(D) In addition to the retirement benefits to which the Executive is entitled under each Pension Plan or any successor plan thereto, the Company shall pay the Executive a lump sum amount, in cash, equal to the excess of (i) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at the date (but in no event earlier than the third anniversary of the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive would have accrued under the terms of all Pension Plans (without regard to any amendment to any Pension Plan made subsequent to a Change in Control and on or prior to the Date of Termination, which amendment adversely affects in any manner the computation of retirement benefits thereunder), determined as if the Executive were fully vested thereunder and had accumulated (after the Date of Termination) thirty-six (36) additional months of service credit thereunder and had been credited under each Pension Plan during such period with compensation equal to the Executive's compensation (as defined in such Pension Plan) during the twelve (12) months immediately preceding the Date of Termination or, if higher, during the twelve months immediately prior to the first occurrence of an event or circumstance constituting Good Reason, over (ii) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at the date (but in no event earlier than the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive had accrued pursuant to the provisions of the Pension Plans as of the Date of Termination. For purposes of this
Section 6.1(D), "actuarial equivalent" shall be determined using the same assumptions utilized under the Sierra Pacific Power Company Retirement Plan immediately prior to the Date of Termination. or, if more favorable to the Executive, immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

5

(E) If the Executive would have become entitled to benefits under Sierra's post-retirement health care or life insurance plans, as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, had the Executive's employment terminated at any time during the period of thirty-six (36) months after the Date of Termination, the Company shall provide such post-retirement health care or life insurance benefits to the Executive and the Executive's dependents commencing on the later of (i) the date on which such coverage would have first become available and (ii) the date on which benefits described in subsection (B) of this Section 6.1 terminate.

6.2 (A) Anything in this Agreement to the contrary notwithstanding, if it is determined (as hereafter provided) that any payment or distribution by the Company, any person whose actions result in a Change in Control or any affiliate of the Company or such person, to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise pursuant to or by reason of any other Agreement, policy, plan, program or arrangement, including without limitation, any stock option, stock appreciation right, or similar right, or the lapse or termination of any restriction on or the vesting or exercisability of any of the foregoing (a "Payment"), would be subject to the excise tax imposed by Section 4999 of the Code (or any successor provision thereto) by reason of being considered "contingent on a change in ownership or control" of the Company, within the meaning of Section 280G of the Code (or any successor provision thereto) or to any similar tax imposed by state or local law, or any interest or penalties with respect to such tax (such tax or taxes, together with any such interest and penalties, are hereafter collectively referred to as the "Excise Tax"), then the Executive will be entitled to receive an additional payment or payments (collectively, a "Gross-Up Payment") in an amount such that, after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including an Excise Tax, imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. No Gross-Up Payment will be made with respect to the Excise Tax, if any, attributable to (a) any incentive stock option, as defined by Section 422 of the Code ("ISO") granted prior to the execution of this Agreement (unless a comparable Gross-Up Payment has theretofore been made available with respect to such option), or (b) any stock appreciation or similar right, whether or not limited, granted in tandem with any ISO described in clause (a).

(B) Subject to the provisions of this Section, all determinations required to be made under this Section, including whether an Excise Tax and whether a Gross-Up Payment is required to be paid by the Company to the Executive and the amount of such Gross-Up Payment, will be made by a nationally recognized firm of certified public accountants (the "Accounting Firm") selected by the Executive in his sole discretion. The Executive will direct the Accounting Firm to submit its determination and detailed supporting calculations to both the Company

6

and the Executive within 15 calendar days after the Executive's termination, if applicable, and any other such time or times as may be requested by the Company or the Executive. If the Accounting Firm determines that any Excise Tax is payable by the Executive, the Company will pay the required Gross-Up Payment to the Executive within five business days after receipt of such determination and calculations with respect to any Payment to the Executive. If the Accounting Firm determines that no Excise Tax is payable by the Executive, it will, at the same time as it makes such determination, furnish the Company and the Executive an opinion that the Executive has substantial authority not to report any Excise Tax on the Executive's federal, state, local income, or other tax return. Any determination by the Accounting Firm as to the amount of the Gross-Up Payment will be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code (or any successor provision thereto) and the possibility of similar uncertainty regarding applicable state or local tax law at the time of any determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments that will not have been made by the Company should have been made (an "Underpayment), consistent with the calculations required to be made hereunder. In the event that the Company exhausts or fails to pursue its remedies pursuant to this Section, and the Executive thereafter is required to make a payment of any Excise Tax, the Executive will direct the Accounting Firm to determine the amount of the Underpayment that has occurred and to submit its determination and detailed supporting calculations to both the Company and the Executive as promptly as possible. Any such Underpayment will be promptly paid by the Company to, or for the benefit of, the Executive within five business days after receipt of such determination and calculations.

(C) The Company and the Executive will each provide the Accounting Firm access to and copies of any books, records, and documents in the possession of the Company or the Executive, as the case may be, reasonably requested by the Accounting Firm, and otherwise cooperate with the Accounting Firm in connection with the preparation and issuance of the determinations and calculations contemplated by this Section.

(D) The federal, state, and local income or other tax returns filed by the Executive will be prepared and filed on a consistent basis with the determination of the Accounting Firm with respect to the Excise Tax payable by the Executive. The Executive will make proper payment of the amount of any Excise Tax, and at the request of the Company, provide to the Company true and correct copies (with any amendments) of the Executive's federal income tax return as filed with the Internal Revenue Service and corresponding state and local tax returns, if relevant, as filed with the applicable taxing authority, and such other documents reasonably requested by the Company, evidencing such payment. If prior to the filing of the Executive's federal income tax return, or corresponding state or local tax return, if relevant, the Accounting Firm determines that the amount of the Gross-Up Payment should be reduced, the Executive will, within five business days, pay to the Company the amount of such reduction.

7

(E) The fees and expenses of the Accounting Firm for its services in connection with the determinations and calculations contemplated by this section will be borne by the Company. If such fees and expenses are initially paid by the Executive, the Company will reimburse the Executive the full amount of such fees and expenses within five business days after receipt from the Executive of a statement therefore and reasonable evidence of his payment thereof.

(F) The Executive will notify the Company in writing of any claim by the Internal Revenue Service or other taxing authority that, if successful, would require the payment by the Company of a Gross-Up Payment. Such notification will be given as promptly as practicable but no later than 10 business days after the Executive actually receives notice of such claim and the Executive will further apprise the Company of the nature of such claim and the date on which such claim is requested to be paid (in each case, to the extent known by the Executive). The Executive will not pay such claim prior to the earlier of (a) the expiration of the 30-calendar-day period following the date on which the Executive gives such notice to the Company, and (b) the date that any payment of amount with respect to such claim is due. If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive will:

(a) provide the Company with any written records or documents in the Executive's possession relating to such claim reasonably requested by the Company;

(b) take such action in connection with contesting such claim as the Company will reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney competent with respect of the subject matter and reasonably selected by the Company;

(c) cooperate with the Company in good faith in order effectively to contest such claim; and

(d) permit the Company to participate in any proceedings relating to such claim;

provided, however, that the Company will bear and pay directly all costs and expenses (including interest and penalties) incurred in connection with such contest and will indemnify and hold harmless the Executive, on an after-tax basis, for and against any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of such representation and payment of costs and expenses. Without limiting the foregoing provisions of this Section, the Company will control all proceedings taken in connection with the contest of any claim contemplated by this Section and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings, and conferences with the taxing

8

authority in respect of such claim (provided, however, that the Executive may participate therein at the Executive's own cost and expense) and may, at its option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction, and in one or more appellate courts, as the Company will determine; provided, however, that the Company directs the Executive to pay the tax claimed and sue for a refund, the Company will advance the amount of such payment to the Executive on an interest-free basis and will indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income or other tax, including interest and penalties with respect thereto, imposed with respect to such advance; and provided further, however, that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which the contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of any such contested claim will be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive will be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(G) If, after the receipt by the Executive of an amount advanced by the Company pursuant to this Section, the Executive receives any refund with respect to such claim, the Executive will (subject to the Company's complying with the requirements of this Section) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after any taxes applicable theret0). If, after the receipt by the Executive of an amount advanced by the Company pursuant to this Section, a determination is made that the Executive will not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial or refund prior to the expiration of 30 calendar days after such determination, then such advance will be forgiven and will not be required to be repaid and the amount of such advance will offset, to the extent thereof, the amount of the Gross-Up Payment required to be paid by the Company to the Executive pursuant to this Section.

6.3 This section intentionally left blank.

6.4 The Company also shall pay to the Executive all legal fees and expenses incurred by the Executive in disputing in good faith any issue hereunder relating to the termination of the Executive's employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Agreement or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of the Executive's written requests for payment accompanied with such evidence of fees and expenses incurred as the Company reasonably may require.

9

6.5 Notwithstanding any other provision of this agreement, if the executive is entitled to and claims benefits under or pursuant to any other change in control agreement entered into between Company or Sierra and the executive, or any terms or conditions thereunder, the executive shall not be entitled to any of the severance benefits or any other benefits under this agreement or terms or conditions of this agreement.

7. Termination Procedures and Compensation During Dispute.

7.1 Notice of Termination. After a Change in Control or potential Change in Control and during the Term, any purported termination of the Executive's employment (other than by reason of death) shall be communicated by written Notice of Termination from one party hereto to the other party hereto in accordance with Section 10 hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive's employment under the provision so indicated. Further, a Notice of Termination for Cause is required to include a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board which was called and held for the purpose of considering such termination (after reasonable notice to the Executive and an opportunity for the Executive, together with the Executive's counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, the Executive was guilty of conduct set forth in clause (i) or (ii) of the definition of Cause herein, and specifying the particulars thereof in detail.

7.2 Date of Termination. "Date of Termination," with respect to any purported termination of the Executive's employment after a Change in Control or potential Change in Control and during the Term, shall mean (i) if the Executive's employment is terminated for Disability, thirty (30) days after Notice of Termination is given (provided that the Executive shall not have returned to the full-time performance of the Executive's duties during such thirty (30) day period), and (ii) if the Executive's employment is terminated for any other reason, the date specified in the Notice of Termination (which, in the case of a termination by Sierra, shall not be less than thirty (30) days (except in the case of a termination for Cause) and, in the case of a termination by the Executive, shall not be less than fifteen (15) days nor more than sixty (60) days, respectively, from the date such Notice of Termination is given).

7.3 Dispute Concerning Termination. If within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of Termination (as determined without regard to this Section 7.3), the party receiving such Notice of Termination notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the earlier of (i) the date on which

10

the Term ends or (ii) the date on which the dispute is finally resolved, either by mutual written agreement of the parties or by a final judgment, order or decree of an arbitrator or a court of competent jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of Termination shall be extended by a notice of dispute given by the Executive only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence.

7.4 Compensation During Dispute. If a purported termination occurs following a Change in Control or potential Change in Control and during the Term and the Date of Termination is extended in accordance with Section 7.3 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, salary) and continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the notice giving rise to the dispute was given, until the Date of Termination, as determined in accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other amounts due under this Agreement (other than those due under Section 5.2 hereof) and shall not be offset against or reduce any other amounts due under this Agreement.

8. No Mitigation. The Company agrees that, if the Executive's employment with Sierra terminates during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to Section 6 hereof or Section 7.4 hereof. Further, the amount of any payment or benefit provided for in this Agreement (other than Section 6.1(B) hereof) shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise.

9. Successors; Binding Agreement.

9.1 In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as the Executive would be entitled to hereunder if the Executive were to terminate the Executive's employment for Good Reason after a Change in Control, except that, for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination.

11

9.2 This Agreement shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms, terminate upon the death of the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive's estate.

10. Notices. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, addressed, if to the Executive, to the address inserted below the Executive's signature on the final page hereof and, if to the Company, to the address set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt:

11. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer as may be specifically designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or of any lack of compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement supersedes any other agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof which have been made by either party; provided, however, that this Agreement shall supersede any agreement setting forth the terms and conditions of the Executive's employment with Sierra only in the event that the Executive's employment with Sierra is terminated on or following a Change in Control or potential Change in Control, by Sierra other than for Cause or by the Executive other than for Good Reason. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of Nevada. All references to sections of the Exchange Act or the Code shall be deemed also to refer to any successor provisions to such sections. Any payments provided for hereunder shall be paid net of any applicable withholding required

12

under federal, state or local law and any additional withholding to which the Executive has agreed. The obligations of the Company and the Executive under this Agreement which by their nature may require either partial or total performance after the expiration of the Term (including, without limitation, those under Sections 6 and 7 hereof) shall survive such expiration.

12. Validity.

12.1 The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

13. Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

14. Settlement of Dispute; Arbitration.

14.1 All claims by the Executive for benefits under this Agreement shall be directed to and determined by the Board and shall be in writing. Any denial by the Board of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the denial and the specific provisions of this Agreement relied upon. The Board shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim and shall further allow the Executive to appeal to the Board a decision of the Board within sixty (60) days after notification by the Board that the Executive's claim has been denied.

14.2 Any further dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Reno, Nevada in accordance with the rules of the American Arbitration Association then in effect; provided, however, that the evidentiary standards set forth in this Agreement shall apply. Judgment may be entered on the arbitrator's award in any court having jurisdiction. Notwithstanding any provision of this Agreement to the contrary, the Executive shall be entitled to seek specific performance of the Executive's right to be paid until the Date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement.

Exhibit 10(C)

CHANGE IN CONTROL AGREEMENT

THIS AGREEMENT, dated May 21, 2001, is made by and between Sierra Pacific Resources, a Nevada corporation (the "Company"), and Dennis D. Schiffel (the "Executive").

WHEREAS, the Company considers it essential to the best interests of its stockholders to foster the continued employment of key management personnel; and

WHEREAS, the Board recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders; and

WHEREAS, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the management of the Company and its subsidiaries (collectively, "Sierra"), including the Executive, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a Change in Control;

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as follows:

1. Defined Terms. The definitions of capitalized term sused in this Agreement are provided in the last Section hereof.

2. Term of Agreement. The term of this Agreement shall commence on the date hereof and shall continue in effect through December 31, 2004; provided, however, that if a Change in Control shall have occurred during the Term shall expire no earlier than twenty-four (24) months beyond the month in which such Change in Control occurred; and further provided, however, that if a Potential Change in Control shall have occurred during the Term, the Term shall expire no earlier than the latter of (a)December 31, 2004 (b) the date on which such potential Change in Control shall have been terminated, or (c) 24 months beyond the date on which such potential Change in Control shall have resulted in a Change of Control.

3. Company's Covenants Summarized. In order to induce the Executive to remain in the employ of Sierra and in consideration of the Executive's covenants set forth in Section 4 hereof, the Company agrees, under the conditions described herein, to pay the Executive the Severance Payments and the other payments and benefits described herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be payable under this Agreement unless there shall have been (or, under the terms of the second sentence of Section 6.1 hereof, there shall be deemed to have been) a termination of the Executive's employment with Sierra following a Change in Control or potential Change in Control and during the Term. This Agreement shall not be construed as creating an express or implied contract of employment and, except as otherwise agreed in writing between the Executive and Sierra, the Executive shall not have any right to be retained in the employ of Sierra. The obligations of the Company hereunder shall be deemed satisfied to the extent payments are made by Sierra Pacific Power, Nevada Power, or any affiliate of the Company or any successor to the Company or any successor to any affiliate of the Company.

4. The Executive's Covenants. The Executive agrees that, subject to the terms and conditions of this Agreement, in the event of a Potential Change in Control during the Term, the Executive will remain in the employ of the Company until the earliest of (i) a date which is six (6) months from the date of such Potential Change of Control, (ii) the date of a Change in Control, (iii) the date of termination by the Executive of the Executive's employment for Good Reason or by reason of death, Disability or Retirement, or
(iv) the termination by Sierra of the Executive's employment for any reason.

5. Compensation Other Than Severance Payments.

5.1 Following a Change in Control or potential Change in Control and during the Term, during any period that the Executive fails to perform the Executive's full-time duties with Sierra as a result of incapacity due to physical or mental illness, the Company shall pay the Executive's full salary to the Executive at the rate in effect at the commencement of any such period, together with all compensation and benefits payable to the Executive under the terms of any compensation or benefit plan, program or arrangement maintained by Sierra during such period, until the Executive's employment is terminated by Sierra for Disability.

5.2 If the Executive's employment shall be terminated for any reason following a Change in Control or potential Change in Control and during the Term, the Company shall pay the Executive's full salary to the Executive through the Date of Termination at the rate in effect immediately prior to the Date of Termination or, if higher, the rate in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, together with all compensation and benefits payable to the Executive through the Date of Termination under the terms of Sierra compensation and benefit plans, programs or arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive,

2

as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

5.3 If the Executive's employment shall be terminated for any reason following a Change in Control or potential Change in Control and during the Term, the Company shall pay to the Executive the Executive's normal post-termination compensation and benefits (other than any severance payments forgone under Section 6.1a) as such payments become due, provided that the Executive is eligible or entitled to such compensation and benefits under the terms and conditions of any such plan or program in effect and provided further that the Executive fully complied with all conditions and requirements of any such plan or program, and provided further that such payments or benefits are not otherwise precluded under the terms of this Agreement. Such post-termination compensation and benefits shall be determined under, and paid in accordance with, Sierra's retirement, insurance and other compensation or benefit plans, programs and arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the occurrence of the first event or circumstance constituting Good Reason.

6. Severance Payments.

6.1 Subject to Section 6.2 hereof, if the Executive's employment is terminated following a Change in Control or Potential Change in Control and during the Term, other than (A) by Sierra for Cause, (B) by reason of death or Disability, or (C) by the Executive without Good Reason, then Sierra shall pay the Executive the amounts, and provide the Executive the benefits,described in this Section 6.1("Severance Payments"), in addition to any payments and benefits to which theExecutive is entitled under Section 5 hereof. For purposes of this Agreement,the Executive's employment shall be deemed to have been terminated following a Change in Control or Potential Change in Control by Sierra without Cause or by the Executive with Good Reason,if (i) the Executive's employment is terminated by Sierra without Cause prior to a Change in Control (whether or not a Change in Control ever occurs) and suchtermination was at the request or direction of a Person who has entered into agreement with the Company the consummation of which would constitute a Changein Control, (ii) the Executive terminates his employment for Good Reason priorto a Change in Control (whether or not a Change in Control ever occurs) and thecircumstance or event which constitutes Good Reason occurs at the request ordirection of such Person, or (iii) the Executive's employment is terminated by Sierra without Cause or by the Executive for Good Reason and such termination or the circumstance or event which constitutes Good Reason is otherwise in connection with or in anticipation of a Change in Control (whether or not a Change in Control ever occurs). For purposes of any determination regarding the applicability of the immediately preceding sentence, any position taken by the Executive shall be presumed to be correct unless the Company establishes to the Board by clear and convincing evidence that such position is not correct.

3

(A) In lieu of any further salary payments to the Executive for periods subsequent to the Date of Termination and in lieu of any severance benefit otherwise payable to the Executive under or pursuant to any contract or plan, except for any severance benefits relating to or resulting from the Supplemental Executive Retirement Plan (provided the Executive is a participant in the Plan), whether as a consequence of a Change in Control or otherwise,subject to the provisions of Section 6.2(a), the Company shall pay to the Executive a lump sum severance payment, in cash, equal to three times the sum of (i) the Executive's base salary as in effect immediately prior to the Date of Termination or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, and (ii) the target annual incentive award applicable to the Executive pursuant to any annual bonus or annual cash incentive plan maintained by Sierra in respect of the fiscal year ending immediately prior to the fiscal year in which occurs the Date of Termination or, if higher, immediately prior to the fiscal year in which occurs the first event or circumstance constituting Good Reason.

(B) For the thirty-six (36) month period immediately following the Date of Termination, the Company shall arrange to provide the Executive and his dependents life, disability, accident and health insurance benefits substantially similar to those provided to the Executive and his dependents immediately prior to the Date of Termination or, if more favorable to the Executive, those provided to the Executive and his dependents immediately prior to the first occurrence of an event or circumstance constituting Good Reason, at no greater cost to the Executive than the cost to the Executive immediately prior to such date or occurrence; provided, however, that, unless the Executive consents to a different method (after taking into account the effect of such method on the calculation of "parachute payments" pursuant to Section 6.2 hereof), such health insurance benefits shall be provided through a third-party insurer. Benefits otherwise receivable by the Executive pursuant to this Section 6.1(B) shall be reduced to the extent benefits of the same type are received by or made available to the Executive during the thirty-six (36) month period following the Executive's termination of employment (and any such benefits received by or made available to the Executive shall be reported to the Company by the Executive); provided, however, that the Company shall reimburse the Executive for the excess, if any, of the cost of such benefits to the Executive over such cost immediately prior to the Date of Termination or, if more favorable to the Executive, the first occurrence of an event or circumstance constituting Good Reason. If the Severance Payments shall be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B) benefits which remain payable after the application of Section 6.2 hereof are thereafter reduced pursuant to the immediately preceding sentence, the Company shall, no later than five (5) business days following such reduction, pay to the Executive the least of (a) the amount of

4

the decrease made in the Severance Payments pursuant to Section 6.2 hereof, (b) the amount of the subsequent reduction in these Section 6.1 (B) benefits, or (c) the maximum amount which can be paid to the Executive without being, or causing any other payment to be, nondeductible by reason of Section 280G of the Code.

(C) Notwithstanding any provision of any annual or long-term incentive plan to the contrary, the Company shall pay to the Executive a lump sum amount, in cash, equal to the sum of (i) any unpaid incentive compensation which has been allocated or awarded to the Executive for a completed fiscal year or other measuring period preceding the Date of Termination under any such plan and which, as of the Date of Termination, is contingent only upon the continued employment of the Executive to a subsequent date, and (ii) a pro rata portion to the Date of Termination of the aggregate value of all contingent incentive compensation awards to the Executive for all then uncompleted periods under any such plan, calculated as to each such award by multiplying the award that the Executive would have earned on the last day of the performance award period, assuming the achievement, at the target level of the individual and corporate performance goals established with respect to such award, by the fraction obtained by dividing the number of full months and any fractional portion of a month during such performance award period through the Date of Termination by the total number of months contained in such performance award period.

(D) In addition to the retirement benefits to which the Executive is entitled under each Pension Plan or any successor plan thereto, the Company shall pay the Executive a lump sum amount, in cash, equal to the excess of (i) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at the date (but in no event earlier than the third anniversary of the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive would have accrued under the terms of all Pension Plans (without regard to any amendment to any Pension Plan made subsequent to a Change in Control and on or prior to the Date of Termination, which amendment adversely affects in any manner the computation of retirement benefits thereunder), determined as if the Executive were fully vested thereunder and had accumulated (after the Date of Termination) thirty-six (36) additional months of service credit thereunder and had been credited under each Pension Plan during such period with compensation equal to the Executive's compensation (as defined in such Pension Plan) during the twelve (12) months immediately preceding the Date of Termination or, if higher, during the twelve months immediately prior to the first occurrence of an event or circumstance constituting Good Reason, over (ii) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at

5

the date (but in no event earlier than the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive had accrued pursuant to the provisions of the Pension Plans as of the Date of Termination. For purposes of this Section 6.1(D), "actuarial equivalent" shall be determined using the same assumptions utilized under the Sierra Pacific Power Company Retirement Plan immediately prior to the Date of Termination. or, if more favorable to the Executive, immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

(E) If the Executive would have become entitled to benefits under Sierra's post-retirement health care or life insurance plans, as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, had the Executive's employment terminated at any time during the period of thirty-six (36) months after the Date of Termination, the Company shall provide such post-retirement health care or life insurance benefits to the Executive and the Executive's dependents commencing on the later of (i) the date on which such coverage would have first become available and (ii) the date on which benefits described in subsection (B) of this Section 6.1 terminate.

6.2 (A) Notwithstanding any other provisions of this Agreement, in the event that any payment or benefit received or to be received by the Executive in connection with a Change in Control or the termination of the Executive's employment (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any Person whose actions result in a Change in Control or any Person affiliated with the Company or such Person) (all such payments and benefits, including the Severance Payments, being hereinafter called "Total Payments") would be subject (in whole or part), to the Excise Tax, then, after taking into account any reduction in the Total Payments provided by reason of section 280G of the Code in such other plan, arrangement or agreement, the cash Severance Payments shall first be reduced, and the non-cash Severance Payments shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (A) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments); provided, however, that the Executive may elect to have the non-cash Severance Payments reduced (or eliminated) prior to any reduction of the cash Severance Payments.

(B) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such

6

time and in such manner as not to constitute a "payment" within the meaning of
Section 280G(b) of the Code shall be taken into account, (ii) no portion of the Total Payments shall be taken into account which, in the opinion of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and selected by the accounting firm (the "Auditor") which was, immediately prior to the Change in Control, the Company's independent auditor, does not constitute a "parachute payment" within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Tax Counsel, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the Base Amount allocable to such reasonable compensation, and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

(C) At the time that payments are made under this Agreement, the Company shall provide the Executive with a written statement setting forth the manner in which such payments were calculated and the basis for such calculations including, without limitation, any opinions or other advice the Company has received from Tax Counsel, the Auditor or other advisors or consultants (and any such opinions or advice which are in writing shall be attached to the statement). If the Executive objects to the Company's calculations, the Company shall pay to the Executive such portion of the Severance Payments (up to 100% thereof) as the Executive with concurrence of tax counsel determine are necessary to result in the proper application of subsection A of this Section 6.2.

6.3 The payments provided in subsections (A), (C) and (D) of
Section 6.1 hereof shall be made not later than the fifth day following the Date of Termination; provided, however, that if the amounts of such payments, and the limitation on such payments set forth in Section 6.2 hereof, cannot be finally determined on or before such day, the Company shall pay to the Executive on such day an estimate, as determined in good faith by the Executive of the minimum amount of such payments to which the Executive is clearly entitled, but in no event to exceed three times the sum of base pay and target annual cash incentive, and shall pay the remainder of such payments (together with interest on the unpaid remainder (or on all such payments to the extent the Company fails to make such payments when due) at 120% of the rate provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined but in no event later than the thirtieth (30th) day after the Date of Termination. In the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Company to the Executive, payable on the fifth (5th) business day after demand by the Company (together with interest at 120% of the rate provided in
Section 1274(b)(2)(B) of the Code).

7

6.4 The Company also shall pay to the Executive all legal fees and expenses incurred by the Executive in disputing in good faith any issue hereunder relating to the termination of the Executive's employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Agreement or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of the Executive's written requests for payment accompanied with such evidence of fees and expenses incurred as the Company reasonably may require.

6.5 Notwithstanding any other provision of this agreement, except as otherwise permitted by this Agreement, if the executive is entitled to and claims benefits under or pursuant to any other change in control agreement entered into between Company or Sierra and the executive, or any terms or conditions thereunder, the executive shall not be entitled to any of the severance benefits or any other benefits under this agreement or terms or conditions of this agreement.

7. Termination Procedures and Compensation During Dispute.

7.1 Notice of Termination. After a Change in Control or potential Change in Control and during the Term, any purported termination of the Executive's employment (other than by reason of death) shall be communicated by written Notice of Termination from one party hereto to the other party hereto in accordance with Section 10 hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive's employment under the provision so indicated. Further, a Notice of Termination for Cause is required to include a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board which was called and held for the purpose of considering such termination (after reasonable notice to the Executive and an opportunity for the Executive, together with the Executive's counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, the Executive was guilty of conduct set forth in clause (i) or (ii) of the definition of Cause herein, and specifying the particulars thereof in detail.

7.2 Date of Termination. "Date of Termination," with respect to any purported termination of the Executive's employment after a Change in Control or potential Change in Control and during the Term, shall mean (i) if the Executive's employment is terminated for Disability, thirty (30) days after Notice of Termination is given (provided that the Executive shall not have returned to the full-time performance of the Executive's duties during such thirty (30) day period), and (ii) if the Executive's employment is terminated for any other reason, the date specified in the Notice of Termination (which, in the case of a termination by Sierra, shall not be less than thirty (30) days (except in the case of a termination for Cause) and, in the

8

case of a termination by the Executive, shall not be less than fifteen (15) days nor more than sixty (60) days, respectively, from the date such Notice of Termination is given).

7.3 Dispute Concerning Termination. If within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of Termination (as determined without regard to this Section 7.3), the party receiving such Notice of Termination notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the earlier of (i) the date on which the Term ends or (ii) the date on which the dispute is finally resolved, either by mutual written agreement of the parties or by a final judgment, order or decree of an arbitrator or a court of competent jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of Termination shall be extended for a period not to exceed six months by a notice of dispute given by the Executive and then only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence and agrees to reimburse the Company for all compensation received from and after the date of termination specified in Section 7.2 in the event the dispute is not resolved in the Executive's favor.

7.4 Compensation During Dispute. If a purported termination occurs following a Change in Control or potential Change in Control and during the Term and the Date of Termination is extended in accordance with Section 7.3 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, salary) and continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the notice giving rise to the dispute was given, until the Date of Termination, as determined in accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other amounts due under this Agreement (other than those due under Section 5.2 hereof) and shall not be offset against or reduce any other amounts due under this Agreement, except that if the notice of dispute is given by the Executive and the term is extended pursuant to Section 7.3 beyond the date specified in accordance with
Section 7.2 and the Executive does not prevail in his dispute, Executive shall reimburse to and refund to the Company all compensation paid after the termination date specified in Section 7.2.

8. No Mitigation. The Company agrees that, if the Executive's employment with Sierra terminates during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to Section 6 hereof or Section 7.4 hereof. Further, the amount of any payment or benefit provided for in this Agreement (other than Section 6.1(B) hereof) shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement

9

benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise.

9. Successors; Binding Agreement.

9.1 In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as the Executive would be entitled to hereunder if the Executive were to terminate the Executive's employment for Good Reason after a Change in Control, except that, for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination.

9.2 This Agreement shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms, terminate upon the death of the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive's estate.

10. Notices. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, addressed, if to the Executive, to the address inserted below the Executive's signature on the final page hereof and, if to the Company, to the address set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt:

WHEREAS, the Company considers it essential to the best interests of its stockholders to foster the continued employment of key management personnel; and

WHEREAS, the Board recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders; and

WHEREAS, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the management of the Company and its subsidiaries (collectively, "Sierra"), including the Executive, to their assigned duties without distraction in the face of potentially dasturbing circumstances arising from the possibility of a Change in Control;

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as follows:

1. Defined Terms. The definitions of capitalized terms used in this Agreement are provided in the last Section hereof.

2. Term of Agreement. The term of this Agreement shall commence on the date hereof and shall continue in effect through December 31, 2004; provided, however, that if a Change in Control shall have occurred during the Term, the Term shall expire no earlier than twenty-four (24) months beyond the month in which such Change in Control occurred; and further provided, however, that if a Potential Change in Control shall have occurred during the Term, the Term shall expire no earlier than the later of (a) December 31, 2004, (b) the date on which such potential Change in Control shall have been terminated, or
(c) 24 months beyond the

1

In order to induce the Executive to remain if the employ of Sierra and in consideration of the Executive's covenants set forth in Section 4 hereof, the Company agrees, under the conditions described herein, to pay the Executive the Severance Payments and the other payments and benefits described herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be payable under this Agreement unless there shall have been (or, under the terms of the second sentence of Section 6.1 hereof, there shall be deemed to have been) a termination of the Executive's employment with Sierra following a Change in Control or potential Change in Control and during the Term. This Agreement shall not be construed as creating an express or implied contract of employment and, except as otherwise agreed in writing between the Executive and Sierra, the Executive shall not have any right to be retained in the employ of Sierra. The obligations of the Company hereunder shall be deemed satisfied to the extent payments are made by Sierra Pacific Power, Nevada Power, or any affiliate of the Company or any successor to the Company or any sucessor to any affiliate of the Company.

4. The Executive's Covenants.

2

payable to the Executive through the Date of Termination under the terms of Sierra compensation and benefit plans, programs or arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

5.3 If the Executive's employment shall be terminated for any reason following a Change in Control or Potential Change in Control and during the Term, the Company shall pay to the Executive the Executive's normal post-termination compensation and benefits (other than any severance payments forgone under Section 6.1a) as such payments become due, provided that the Executive is eligible or entitled to such compensation and benefits under the terms and conditions of any such plan or program in effect and provided further that the Executive fully complied with all conditions and requirements of any such plan or program, and provided further that such payments or benefits are not otherwise precluded under the terms of this Agreement. Such post-termination compensation and benefits shall be determined under, and paid in accordance with, Sierra's retirement, insurance and other compensation or benefit plans, programs and arrangements as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the occurrence of the first event or circumstance constituting Good Reason.

6. Severance Payments.

6.1 Subject to Section 6.2 hereof, and subject to the limitations specified in Sections 15.G.V, 15.O, in the case of an impacted Executive which

provisions shall control over the provisions of these Sections 6.1 and 6.2 if the Executive's employment is terminated following a Change in Control or Potential Change in Control and during the Term, other than (A) by Sierra for Cause, (B) by reason of death or Disability, or (C) by the Executive without Good Reason, then Sierra shall pay the Executive the amounts, and provide the Executive the benefits, described in this Section 6.1 ("Severance Payments"), in addition to any payments and benefits to which the Executive is entitled under Section 5 hereof. For purposes of this Agreement, the Executive's employment shall be deemed to have been terminated following a Change in Control by Sierra without Cause or by the Executive with Good Reason, if (i) the Executive's employment is terminated by Sierra without Cause prior to a Change in Control (whether or not a Change in Control ever occurs) and such termination was at the request or direction of a Person who has entered into an agreement with the Company the consummation of which would constitute a Change in Control, (ii) the Executive terminates his employment for Good Reason prior to a Change in Control (whether or not a Change in Control ever occurs) and the circumstance or event which constitutes Good Reason occurs at the request or direction of such Person, or (iii) the Executive's employment is terminated by Sierra without Cause or by the Executive for Good Reason and such termination or the circumstance or event which constitutes Good Reason is otherwise in connection with or in anticipation of a

3

Change in Control (whether or not a Change in Control ever occurs). For purposes of any determination regarding the applicability of the immediately preceding sentence, any position taken by the Executive shall be presumed to be correct undess the Company establishes to the Board by clear and convincing evidence that such position is not correct.

(A) In lieu of any further salary payments to the Executive for periods subsequent to the Date of Termination and in lieu of any severance benefit otherwise payable to the Executive under or pursuant to any contract or plan, except for any severance benefits relating to or resulting from the Supplemental Executive Retirement Plan (provided the Executive is a participant in the Plan), whether as a consequence of a Change in Control or otherwise, and subject to the provisions of Section 6.2(a), the Company shall pay to the Executive a lump sum severance payment, in cash, equal to two times the sum of (i) the Executive's base salary as in effect immediately prior to the Date of Termination or, if higher, in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, and (ii) the target annual cash incentive award applicable to the Executive pursuant to any annual cash bonus or annual cash incentive plan maintained by Sierra in respect of the fiscal year ending immediately prior to the fiscal year in which occurs the Date of Termination or, if higher, immediately prior to the fiscal year in which occurs the first event or circumstance constituting Good Reason.

(B) For the twenty-four (24) month period immediately following the Date of Termination, the Company shall arrange to provide the Executive and his dependents life, disability, accident and health insurance benefits substantially similar to those provided to the Executive and his dependents immediately prior to the Date of Termination or, if more favorable to the Executive, those provided to the Executive and his dependents immediately prior to the first occurrence of an event or circumstance constituting Good Reason, at no greater cost to the Executive than the cost to the Executive immediately prior to such date or occurrence; provided, however, that, unless the Executive consents to a different method (after taking into account the effect of such method on the calculation of "parachute payments" pursuant to Section 6.2 hereof), such health insurance benefits shall be provided through a third-party insurer. Benefits otherwise receivable by the Executive pursuant to this
Section 6.1(B) shall be reduced to the extent benefits of the same type are received by or made available to the Executive during the twenty-four
(24) month period following the Executive's termination of employment (and any such benefits received by or made available to the Executive shall be reported to the Company by the Executive); provided, however, that the Company shall reimburse the Executive for the excess, if any, of the cost of such benefits to the Executive over such cost immediately prior to the Date of Termination or, if more favorable to the Executive, the first occurrence of an event or circumstance constituting Good Reason. If the Severance Payments

4

shall be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B) benefits which remain payable after the application of Section 6.2 hereof are thereafter reduced pursuant to the immediately preceding sentence, the Company shall, no later than five (5) business days following such reduction, pay to the Executive the least of (a) the amount of the decrease made in the Severance Payments pursuant to Section 6.2 hereof,
(b) the amount of the subsequent reduction in these Section 6.1(B) benefits, or (c) the maximum amount which can be paid to the Executive without being, or causing any other payment to be, nondeductible by reason of Section 280G of the Code.

(C) Notwithstanding any provision of any annual or long-term incentive plan to the contrary, the Company shall pay to the Executive a lump sum amount, in cash, equal to the sum of (i) any unpaid incentive compensation which has been allocated or awarded to the Executive for a completed fiscal year or other measuring period preceding the Date of Termination under any such plan and which, as of the Date of Termination, is contingent only upon the continued employment of the Executive to a subsequent date, and (ii) a pro rata portion to the Date of Termination of the aggregate value of all contingent incentive compensation awards to the Executive for all then uncompleted periods under any such plan, calculated as to each such award by multiplying the award that the Executive would have earned on the last day of the performance award period, assuming the achievement, at the target level of the individual and corporate performance goals established with respect to such award, by the fraction obtained by dividing the number of full months and any fractional portion of a month during such performance award period through the Date of Termination by the total number of months contained in such performance award period.

(D) In addition to the retirement benefits to which the Executive is entitled under each Pension Plan or any successor plan thereto, the Company shall pay the Executive a lump sum amount, in cash, equal to the excess of (i) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at the date (but in no event earlier than the third anniversary of the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive would have accrued under the terms of all Pension Plans (without regard to any amendment to any Pension Plan made subsequent to a Change in Control and on or prior to the Date of Termination, which amendment adversely affects in any manner the computation of retirement benefits thereunder), determined as if the Executive were fully vested thereunder and had accumulated (after the Date of Termination) twenty-four (24) additional months of service credit thereunder and had been credited under each Pension Plan during such period with compensation equal to the Executive's compensation (as defined in such Pension Plan) during the twelve (12) months immediately preceding the Date of Termination gr, if higher, during

5

the twelve months immediately prior to the first occurrence of an event or circumstance constituting Good Reason, over (ii) the actuarial equivalent of the aggregate retirement pension (taking into account any early retirement subsidies associated therewith and determined as a straight life annuity commencing at the date (but in no event earlier than the Date of Termination) as of which the actuarial equivalent of such annuity is greatest) which the Executive had accrued pursuant to the provisions of the Pension Plans as of the Date of Termination. For purposes of this
Section 6.1(D), "actuarial equivalent" shall be determined using the same assumptions utilized under the Sierra Pacific Power Company Retirement Plan immediately prior to the Date of Termination. or, if more favorable to the Executive, immediately prior to the first occurrence of an event or circumstance constituting Good Reason.

(E) If the Executive would have become entitled to benefits under Sierra's post-retirement health care or life insurance plans, as in effect immediately prior to the Date of Termination or, if more favorable to the Executive, as in effect immediately prior to the first occurrence of an event or circumstance constituting Good Reason, had the Executive's employment terminated at any time during the period of twenty-four (24) months after the Date of Termination, the Company shall provide such post-retirement health care or life insurance benefits to the Executive and the Executive's dependents commencing on the later of (i) the date on which such coverage would have first become available and (ii) the date on which benefits described in subsection (B) of this Section 6.1 terminate.

6.2 (A) Notwithstanding any other provisions of this Agreement, in the event that any payment or benefit received or to be received by the Executive in connection with a Change in Control or the termination of the Executive's employment (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any Person whose actions result in a Change in Control or any Person affiliated with the Company or such Person) (all such payments and benefits, including the Severance Payments, being hereinafter called "Total Payments") would be subject (in whole or part), to the Excise Tax, then, after taking into account any reduction in the Total Payments provided by reason of section 280G of the Code in such other plan, arrangement or agreement, the cash Severance Payments shall first be reduced, and the non-cash Severance Payments shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (A) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments); provided, however, that the Executive may elect to have the non-cash Severance Payments reduced (or eliminated) prior to any reduction of the cash Severance Payments.

6

(B) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a "payment" within the meaning of Section 280G(b) gf the Code shall be taken into account, (ii) no portion of the Total Payments shall be taken into account which, in the opinion of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and selected by the accounting firm (the "Auditor") which was, immediately prior to the Change in Control, the Company's independent auditor, does not constitute a "parachute payment" within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Tax Counsel, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the Base Amount allocable to such reasonable compensation, and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

(C) At the time that payments are made under this Agreement, the Company shall provide the Executive with a written statement setting forth the manner in which such payments were calculated and the basis for such calculations including, without limitation, any opinions or other advice the Company has received from Tax Counsel, the Auditor or other advisors or consultants (and any such opinions or advice which are in writing shall be attached to the statement). If the Executive objects to the Company's calculations, the Company shall pay to the Executive such portion of the Severance Payments (up to 100% thereof) as the Executive with concurrence of tax counsel determine are necessary to result in the proper application of subsection A of this Section 6.2.

6.3 The payments provided in subsections (A), (C) and (D) of Section 6.1 hereof shall be made not later than the fifth day following the Date of Termination; provided, however, that if the amounts of such payments, and the limitation on such payments set forth in Section 6.2 hereof, cannot be finally determined on or before such day, the Company shall pay to the Executive on such day an estimate, as determined in good faith by the Executive of the minimum amount of such payments to which the Executive is clearly entitled, but in no event to exceed two times the sum of base pay and target annual cash incentive, and shall pay the remainder of such payments (together with interest on the unpaid remainder (or on all such payments to the extent the Company fails to make such payments when due) at 120% of the rate provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined but in no event later than the thirtieth (30th) day after the Date of Termination. In the eveft that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Company to the Executive, payable

7

on the fifth (5th) business day after demand by the Company (together with interest at 120% of the rate provided in Section 1274(b)(2)(B) of the Code).

6.4 The Company also shall pay to the Executive all legal fees and expenses incurred by the Executive in disputing in good faith any issue hereunder relating to the termination of the Executive's employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Agreement or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of the Executive's written requests for payment accompanied with such evidence of fees and expenses incurred as the Company reasonably may require.

6.5 Notwithstanding any other provision of this agreement, except as otherwise permitted by this Agreement, if the Executive is entitled to and claims benefits under or pursuant to any other change in control agreement entered into between Company or Sierra and the executive, or any terms or conditions thereunder, the executive shall not be entitled to any of the severance benefits or any other benefits under this agreement or terms or conditions of this agreement.

7. Termination Procedures and Compensation During Dispute.

7.1 Notice of Termination. After a Change in Control or potential Change in Control and during the Term, any purported termination of the Executive's employment (other than by reason of death) shall be communicated by written Notice of Termination from one party hereto to the other party hereto in accordance with Section 10 hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive's employment under the provision so indicated. Further, a Notice of Termination for Cause is required to include a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board which was called and held for the purpose of considering such termination (after reasonable notice to the Executive and an opportunity for the Executive, together with the Executive's counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, the Executive was guilty of conduct set forth in clause (i) or (ii) of the definition of Cause herein, and specifying the particulars thereof in detail.

7.2 Date of Termination. "Date of Termination," with respect to any purported termination of the Executive's employment after a Change in Control or potential Change in Control and during the Term, shall mean (i) if the Executive's employment is terminated for Disability, thirty (30) days after Notice of Termination is given (provided that the Executive shall not have returned to the full-time performance of the Executive's duties during such thirty (30) day period), and (ii) if

8

the Executive's employment is terminated for any other reason, the date specified in the Notice of Termination (which, in the case of a termination by Sierra, shall not be less than thirty (30) days (except in the case of a termination for Cause) and, in the case of a termination by the Executive, shall not be less than fifteen (15) days nor more than sixty (60) days, respectively, from the date such Notice of Termination is given).

7.3 Dispute Concerning Termination. If within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of Termination (as determined without regard to this Section 7.3), the party receiving such Notice of Termination notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the earlier of (i) the date on which the Term ends or (ii) the date on which the dispute is finally resolved, either by mutual written agreement of the parties or by a final judgment, order or decree of an arbitrator or a court of competent jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of Termination shall be extended for a period not to exceed six months by a notice of dispute given by the Executive and then only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence and agrees to reimburse the Company for all compensation received from and after the date of termination specified in Section 7.2 in the event the dispute is not resolved in the Executive's favor.

7.4 Compensation During Dispute. If a purported termination occurs following a Change in Control or potential Change in Control and during the Term and the Date of Termination is extended in accordance with Section 7.3 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, salary) and continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the notice giving rise to the dispute was given, until the Date of Termination, as determined in accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other amounts due under this Agreement (other than those due under Section 5.2 hereof) and shall not be offset against or reduce any other amounts due under this Agreement, except that if the notice of dispute is given by the Executive and the term is extended pursuant to Section 7.3 beyond the date specified in accordance with
Section 7.2 and the Executive does not prevail in his dispute, Executive shall reimburse to and refund to the Company all compensation paid after the termination date specified in Section 7.2.

8. No Mitigation. The Company agrees that, if the Executive's employment with Sierra terminates during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to Section 6 hereof or
Section 7.4 hereof. Further, the amount of any payment or benefit provided for in this Agreement (other

9

than Section 6.1(B) hereof) shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise.

9. Successors; Binding Agreement.

9.1 In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as the Executive would be entitled to hereunder if the Executive were to terminate the Executive's employment for Good Reason after a Change in Control, except that, for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination.

9.2 This Agreement shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms, terminate upon the death of the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive's estate.

10. Notices. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, addressed, if to the Executive, to the address inserted below the Executive's signature on the final page hereof and, if to the Company, to the address set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt:

11. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and the Company, acting through such officer as may be specifically designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or of any lack of compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement supersedes any other agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof which have been made by either party; provided, however, that this Agreement shall supersede any agreement setting forth the terms and conditions of the Executive's employment with Sierra only in the event that the Executive's employment with Sierra is terminated on or following a Change in Control or potential Change in Control, by Sierra other than for Cause or by the Executive other than for Good Reason. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of Nevada. All references to sections of the Exchange Act or the Code shall be deemed also to refer to any successor provisions to such sections. Any payments provided for hereunder shall be paid net of any applicable withholding required under federal, state or local law and any additional withholding to which the Executive has agreed. The obligations of the Company and the Executive under this Agreement which by their nature may require either partial or total performance after the expiration of the Term (including, without limitation, those under Sections 6 and 7 hereof) shall survive such expiration.

12. Validity.

12.1 The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

13. Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

14. Settlement of Dispute; Arbitration.

14.1 All claims by the Executive for benefits under this Agreement shall be directed to and determined by the Board and shall be in writing. Any denial by the Board of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the denial and the specific provisions of this Agreement relied upon. The Board shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim and shall further allow the Executive to appeal to the Board a decision of the Board

11

within sixty (60) days after notification by the Board that the Executive's claim has been denied.

14.2 Any further dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Las Vegas, Nevada in accordance with the rules of the American Arbitration Association then in effect; provided, however, that the evidentiary standards set forth in this Agreement shall apply. Judgment may be entered on the arbitrator's award in any court having jurisdiction. Notwithstanding any provision of this Agreement to the contrary, the Executive shall be entitled to seek specific performance of the Executive's right to be paid until the Date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement.

"Acceptable Rate Case" means the issuance of a final, nonappealable order of the Public Utilities Commission of Nevada with respect to the Borrower's application to clear its deferred energy accounts, which application is scheduled to be filed on or before December 1, 2002, provided that such order (i) finds that the Borrower's electricity rates that went into effect on March 1, 2001 pursuant to the Comprehensive Energy Plan are just and reasonable and reflect prudent business practices and (ii) authorizes the Borrower to recover 100% of its deferred fuel and power costs accrued through the date of such application.

"Adjusted LIBO Rate" means, with respect to any Eurodollar Revolving Borrowing for any Interest Period, an interest rate per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration.

(d) Notice by the Administrative Agent to Lenders. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing.

(e) Failure to Elect; Events of Default. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.06 Termination, Reduction and Extension of Commitments.

(a) Scheduled Termination. Unless previously terminated, the Commitments shall terminate on the Revolving Termination Date.

(b) Voluntary Termination or Reduction. The Borrower may at any time prior to the Revolving Termination Date terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount of $25,000,000 or a multiple of $1,000,000 in excess thereof and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with
Section 2.08, the sum of the total Revolving Credit Exposures would exceed the total Commitments.

(c) Notice of Voluntary Termination or Reduction. The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such

-20-

termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

(d) Effect of Termination or Reduction. Any termination or reduction of the Commitments shall be permanent. Except as otherwise provided in
Section 2.06(e) (i), each reduction of the Commitments shall be made ratably among the Lenders in accordance with their Applicable Percentages.

(e) Extension of Commitments.

(i) Not earlier than the date which is 60 days (but not later than 30 days) prior to the then existing Revolving Termination Date (the "Extension Request Notice Date"), the Borrower may deliver to the Administrative Agent (which shall promptly transmit the same to each Lender) a notice (an "Extension Request") requesting that the Revolving Termination Date be extended for an additional 364 days commencing on the then existing Revolving Termination Date. Not earlier than the date which is 30 days (but not later than 20 days) prior to the then existing Revolving Termination Date (the period from the Extension Request Notice Date to such date, the "Extension Request Period"), each Lender (in its sole and absolute discretion and after conducting an internal credit review of the Borrower) shall notify the Administrative Agent of such Lender's willingness or unwillingness to so extend the Revolving Termination Date. Any Lender which shall fail to so notify the Administrative Agent within such period shall be deemed to have declined to extend the Revolving Termination Date. If Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect agree to such extension by notice to the Administrative Agent, then (A) subject to clause (iii) below, the Revolving Termination Date shall be extended for an additional 364 days with respect to the Commitments of the Lenders so agreeing, and (B) subject to Section 2.06(f) hereof, the Commitment of each Lender not so agreeing shall expire on the then expiring Revolving Termination Date and the Borrower shall pay or prepay on such day without premium or penalty all principal of such Lender's Loans together with accrued interest thereon and all accrued facility fees and other amounts payable to such Lender hereunder (including, without limitation, amounts payable pursuant to Section 2.13 hereof as a result of such payment or prepayment); provided, however, that

(x) if Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect do not agree as contemplated by
Section 2.06(e)(i), then the Revolving Termination Date shall not be extended pursuant to this Section 2.06(e) and the Commitments of all of the Lenders shall remain in effect until the Revolving Termination Date except as otherwise provided in this Agreement; and

-21-

(y) the Borrower may not request any extension of the Revolving Termination Date pursuant to this Section 2.06(e)(i) more frequently than once in any calendar year.

(ii) Any Loan by any Lender the Commitment of which is to terminate pursuant to Section 2.06(e)(i) hereof that would otherwise be made or converted by such Lender as a Eurodollar Loan having an Interest Period ending after the date such Commitment is to terminate shall be made or continued as an ABR Loan and all ABR Loans of such Lender that would otherwise be converted into Eurodollar Loans having such Interest Periods shall remain as ABR Loans.

(iii) It shall be a condition precedent to any extension of the Revolving Termination Date that: (a) on the date of such extension no Default or Event of Default shall have occurred and be continuing;
(b) the representations and warranties made by the Borrower in Article III shall be true and correct on and as of the date of such extension (or if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and (c) on the date of such extension there shall have been no material adverse change in the consolidated financial condition, operations, business or prospects taken as a whole of the Borrower and its Subsidiaries from that set forth in its financial statements as of September 30, 2001 referred to in Section 3.06 hereof or, if the Borrower has delivered its financial statements for any fiscal year to the Lenders and the Administrative Agent pursuant to Section 5.01(a) hereof, as of the date of the most recent such financial statements. Each request for an extension of the Revolving Termination Date pursuant to Section 2.06(e) shall constitute a certification by the Borrower to the effect set forth in the preceding sentence (both as of the date of such request and, unless the Borrower notifies the Administrative Agent prior to the date of such extension, as of the date of such extension).

(f) Substitute Lenders. In the event any Lender does not agree to any extension by the date provided pursuant to Section 2.06(e) hereof, then, unless a Default or an Event of Default shall have occurred and be continuing, the Borrower may, not later than 10 days following the expiration of the Extension Request Period, designate one or more other banks (each such bank being herein called a "Substitute Lender"), which may include any of the Lenders, acceptable to the Administrative Agent (which acceptance will not be unreasonably withheld), to assume such non-consenting Lender's Commitment hereunder and to purchase, on or before the date such Lender's Loans would otherwise be required to be paid or prepaid hereunder, the Loans and Notes of such Lender and such Lender's rights hereunder in respect thereof, without recourse to or representation or warranty by, or expense to, such Lender. In such event, the purchase price shall be equal to the outstanding principal amount of the Loans and Notes payable to such Lender plus any accrued but unpaid interest on such Loans and Notes and accrued but unpaid facility fees in respect of such Lender's Commitment. Upon such assumption and purchase and the receipt by such Lender of any other amounts payable to it by the Borrower under this Agreement, and subject to the execution and delivery to the Administrative Agent and such Lender by the Substitute Lender of documentation reasonably satisfactory to the Administrative Agent and such Lender pursuant to which such Substitute Lender shall assume the obligations of such original Lender under this Agreement in respect of its Loans, Notes and Commitment and agree to become a "Lender" hereunder (if not already a Lender) to the extent of the Commitments, Loans and Notes assumed and purchased, the

-22-

Substitute Lender shall succeed to the rights, obligations and benefits of such Lender hereunder in such respect (except for such rights, obligations and benefits of the Lender as have accrued (other than principal, accrued interest or facility fees) or are required to be performed by it on or prior to the date of such assumption and purchase) (and such Lender shall be released from its Commitment except for any liability arising or relating to any event occurring prior to the date of such assumption and purchase) and the Substitute Lender shall be deemed to have agreed to the relevant extension of the Revolving Termination Date and, anything in Section 2.06(e) to the contrary notwithstanding, whether such extension is effective shall be determined accordingly; provided that following any such assumption and purchase the Commitments of each Substitute Lender (including any Commitments theretofore held by it) shall be not less than $10,000,000.

SECTION 2.07 Repayment of Loans; Evidence of Debt.

(a) Repayment. The Borrower hereby unconditionally promises to pay to the Administrative Agent for account of the Lenders the outstanding principal amount of the Revolving Loans on the Revolving Termination Date.

(b) Manner of Payment. Prior to any repayment or prepayment of any Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings to be paid and shall notify the Administrative Agent by telephone (confirmed by telecopy) of such selection not later than 12:00 noon, New York, New York time, three Business Days before the scheduled date of such repayment or prepayment; provided that each repayment or prepayment of Borrowings shall be applied to repay or prepay any outstanding ABR Borrowings before any other Borrowings. If the Borrower fails to make a timely selection of the Borrowing or Borrowings to be repaid or prepaid, such payment shall be applied, first, to pay any outstanding ABR Borrowings and, second, to other Borrowings in the order of the remaining duration of their respective Interest Periods (the Borrowing with the shortest remaining Interest Period to be repaid first). Each payment of a Revolving Borrowing shall be applied ratably to the Loans included in such Borrowing.

(c) Maintenance of Loan Accounts by Lenders. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(d) Maintenance of Loan Accounts by the Administrative Agent.
The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder and the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

(e) Effect of Entries. The entries made in the accounts maintained pursuant to paragraphs (c) and (d) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

-23-

(f) Notes. Any Lender may request that Loans made by it be evidenced by a promissory note (each a "Note") in substantially the form of

Exhibit C. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in the form of Exhibit C. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 9.12) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

SECTION 2.08 Prepayment of Loans.

(a) Optional Prepayments Right to Prepay Borrowings. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section.

(b) Notices, Etc. The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any optional prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York, New York time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York, New York time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by
Section 2.06(c), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(c). Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an aggregate principal amount equal to $5,000,000 and a multiple of $1,000,000 in excess thereof; provided that if any prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Revolving Loans made pursuant to such Borrowing to an amount less than $5,000,000, such outstanding Loans shall immediately be converted into ABR Loans. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.10 and shall be made in the manner specified in this Section 2.08(b).

SECTION 2.09 Fees.

(a) Facility Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender a facility fee for the period from and including the Effective Date to but excluding the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated) computed at a rate per annum equal to the Applicable Rate on each Lender's daily average Commitment, such fee to be paid quarterly in arrears on each Quarterly Date and on the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated). The facility fee shall be calculated on the basis of the actual number of days elapsed in a year of 360 days.

-24-

(b) Fee Letter. The Borrower agrees to pay to the Administrative Agent, for the account of the Administrative Agent and the Co-Lead Arrangers, the fees agreed to by the Borrower, SPPC, Sierra Pacific Resources, the Administrative Agent and the Co-Lead Arrangers pursuant to that certain letter agreement, dated the date hereof (the "Fee Letter"), or as otherwise agreed from time to time.

(c) Payment of Fees. All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of facility fees, to the Lenders entitled thereto.

SECTION 2.10 Interest.

(a) ABR Loans. The Loans comprising each ABR Revolving Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate.

(b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Default Interest. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% above the higher of (A) the rate otherwise applicable to such Loan as provided above and (B) the rate applicable to ABR Loans as provided in paragraph (a) of this Section, or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d) Payment of Interest. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (x) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (y) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the Revolving Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (z) in the event of any conversion of any Eurodollar Borrowing prior to the end of the current Interest Period therefor, accrued interest on such Borrowing shall be payable on the effective date of such conversion.

(e) Computation. All interest hereunder shall be computed on the basis of a year of 360 days, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive, absent manifest error.

-25-

SECTION 2.11 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Revolving Borrowing.

SECTION 2.12 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or its Parent (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or its Parent or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender or its Parent of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of its Parent as a consequence of this Agreement or the Loans made by such Lender to a level below that which such Lender or its Parent could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of its Parent with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent for any such reduction suffered.

-26-

(c) Certificates from Lenders. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its Parent, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation.

SECTION 2.13 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable under Section 2.08(b) and is revoked in accordance herewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to
Section 2.16, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an Affiliate of such Lender) for dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.14 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, each Co-Lead Arranger, the Syndication Agent or each Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower

-27-

shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable Law.

(b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Co-Lead Arranger, the Syndication Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Co-Lead Arranger, the Syndication Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, a Co-Lead Arranger, the Syndication Agent or the Administrative Agent (on its own behalf or on behalf of a Lender, a Co-Lead Arranger or the Syndication Agent) shall be conclusive, absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable Law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without withholding or at a reduced rate.

SECTION 2.15 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.12, 2.13 or 2.14, or otherwise) prior to 1:00 PM, New York, New York time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any such date shall be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its Principal Office and to such account at its Principal Office as the Administrative Agent shall specify to the Borrower, except that payments pursuant to Sections 2.12, 2.13, 2.14 and 9.04 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the

-28-

next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Revolving Borrowing shall be made from the Lenders, each payment of facility fees under Section 2.09 shall be made for the account of the Lenders, and each termination or reduction of the amount of the Commitments under Section 2.06 shall be applied to the respective Commitments of the Lenders, pro rata according to the amounts of their respective Commitments;
(ii) each Borrowing shall be allocated pro rata among the Lenders according to the amounts of their respective Commitments (in the case of the making of Revolving Loans) or their respective Loans (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders.

(d) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon then due than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

-29-

(e) Presumptions of Payment. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate.

(f) Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or 2.15(e), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.16 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.12), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.14,

-30-

such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE III
REPRESENTATIONS AND WARRANTIES

SECTION 3.20 ERISA.

(a) Each Plan (and each related trust, insurance contract or fund) is in substantial compliance with its terms and with all applicable Laws, including without limitation ERISA and the Code; each Plan (and each related trust, if any) which is intended to be qualified under Section 401(a) of the Code has received a determination letter from the Internal Revenue Service to the effect that it meets the requirements of Sections 401(a) and 501(a) of the Code; no Reportable Event has occurred; no Multiemployer Plan is insolvent or in reorganization; no Plan has an Unfunded Current Liability; no Plan which is subject to Section 412 of the Code or Section 302 of ERISA has an accumulated funding deficiency within the meaning of such sections of the Code or ERISA or has applied for or received a waiver of an accumulated funding deficiency or an extension of any amortization period within the meaning of Section 412 of the Code or Section 303 or 304 of ERISA; all contributions required to be made with respect to a Plan have been timely made; neither the Borrower nor any Subsidiary of the Borrower nor any ERISA Affiliate has incurred any material liability (including any indirect, contingent or secondary liability) to or on account of a Plan pursuant to Section 409, 502(i), 502(l), 515, 4062, 4063, 4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a)(29), 4971 or 4975 of the Code or expects to incur any such liability under any of the foregoing sections with respect to any Plan; no condition exists which presents a material risk to the Borrower or any Subsidiary of the Borrower or any ERISA Affiliate of incurring a liability to or on account of a Plan pursuant to the foregoing provisions of ERISA and the Code; no proceedings have been instituted to terminate or appoint a trustee to administer any Plan; no action, suit, proceeding, hearing, audit or investigation with respect to the administration, operation or the investment of assets of any

-36-

Plan (other than routine claims for benefits) is pending, expected or threatened; using actuarial assumptions and computation methods consistent with Part 1 of subtitle E of Title IV of ERISA, the aggregate liabilities of the Borrower and its Subsidiaries and its ERISA Affiliates to all Multiemployer Plans in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of each such Plan ended prior to the date of the most recent Borrowing, would not have a Material Adverse Effect; each group health plan (as defined in Section 607(1) of ERISA or Section 4980B(g)(2) of the Code) which covers or has covered employees or former employees of the Borrower, any Subsidiary of the Borrower, or any ERISA Affiliate has at all times been operated in compliance with the provisions of Part 6 of subtitle B of Title I of ERISA and Section 4980B of the Code; no Lien imposed under the Code or ERISA on the assets of the Borrower or any Subsidiary of the Borrower or any ERISA Affiliate exists or is likely to arise on account of any Plan; and the Borrower and its Subsidiaries may cease contributions to or terminate any Plan maintained by any of them without incurring any material liability.

All contributions required to be made with respect to a Foreign Pension Plan have been timely made. Neither the Borrower nor any of its Subsidiaries has incurred any obligation in connection with the termination of or withdrawal from any Foreign Pension Plan. The present value of the accrued benefit liabilities (whether or not vested) under each Foreign Pension Plan, determined as of the end of the Borrower's most recently ended fiscal year on the basis of actuarial assumptions, each of which is reasonable, did not exceed the current value of the assets of such Foreign Pension Plan allocable to such benefit liabilities.

Upon the effective date of resignation or removal of a retiring Administrative Agent, the Administrative Agent shall be discharged from its duties under this Agreement and the other Loan Documents, but the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted by it while it was Administrative Agent under this Agreement. If and for so long as no successor Administrative Agent shall have been appointed, then any notice or other communication required or permitted to be given by the Administrative Agent shall be sufficiently given if given by the Required Lenders, all notices or other communications required or permitted to be given to the Administrative Agent shall be given to each Lender, and all payments to be made to the Administrative Agent shall be made directly to the Borrower or Lender for whose account such payment is made.

SECTION 8.11 Additional Administrative Agents.

If and to the extent that the foregoing obligations of the Borrower under this subsection (c), or any other indemnification obligation of the Borrower hereunder or under any other Loan Document, are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under applicable Law.

SECTION 9.05 Severability.

The provisions of this Agreement are intended to be severable. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or

unenforceability without in any manner affecting the validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction.

SECTION 9.06 Prior Understandings.

This Agreement and the other Loan Documents, as such agreements shall be amended from time to time, supersede all prior and contemporaneous understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein and therein.

SECTION 9.07 Duration; Survival.

All representations and warranties of the Borrower contained herein or in any other Loan Document or made in connection herewith or therewith shall survive the making, and shall not be waived by the execution and delivery, of this Agreement or any other Loan Document, any investigation by or knowledge of the Administrative Agent or any Lender, the making of any Loan, or any other event or condition whatever. All covenants and agreements of the Borrower contained herein or in any other Loan Document shall continue in full force and effect from and after the date hereof so long as the Borrower may borrow hereunder and until payment in full of all Obligations. Without limitation, all obligations of the Borrower hereunder or under any other Loan Document to make payments to or indemnify the Administrative Agent or any Lender shall survive the payment in full of all other Obligations, termination of the Borrower's right to borrow hereunder, and all other events and conditions whatever. In addition, all obligations of each Lender to make payments to or indemnify the Administrative Agent shall survive the payment in full by the Borrower of all Obligations, termination of the Borrower's right to borrow hereunder, and all other events or conditions whatever.

SECTION 9.08 Counterparts.

This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument.

SECTION 9.09 Limitation on Payments.

The parties hereto intend to conform to all applicable Laws in effect from time to time limiting the maximum rate of interest that may be charged or collected. Accordingly, notwithstanding any other provision hereof or of any other Loan Document, the Borrower shall not be required to make any payment to or for the account of any Lender, and each Lender shall refund any payment made by the Borrower, to the extent that such requirement or such failure to refund would violate or conflict with nonwaivable provisions of applicable Laws limiting the maximum amount of interest which may be charged or collected by such Lender.

SECTION 9.10 Set-Off.

The Borrower hereby agrees that, to the fullest extent permitted by Law, if any Obligation of the Borrower shall be due and payable (by acceleration or otherwise), each Lender shall have the right, without notice to the Borrower, to set-off against and to appropriate and

-65-

apply to such Obligation any indebtedness, liability or obligation of any nature owing to the Borrower by such Lender, including but not limited to all deposits (whether time or demand, general or special, provisionally credited or finally credited, whether or not evidenced by a certificate of deposit) now or hereafter maintained by the Borrower with such Lender. Such right shall be absolute and unconditional in all circumstances and, without limitation shall exist whether or not such Lender or any other Person shall have given notice or made a demand to the Borrower or any other Person, whether such indebtedness, obligation or liability owed to the Borrower is contingent, absolute, matured or unmatured (it being agreed that such Lender may deem such indebtedness, obligation or liability to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty or any other security, right or remedy available to any Lender or any other Person. The Borrower hereby agrees that, to the fullest extent permitted by Law, any Participant and any branch, subsidiary or affiliate of any Lender or any Participant shall have the same rights of set-off as a Lender as provided in this Section (regardless of whether such Participant, branch, subsidiary or affiliate would otherwise be deemed in privity with or a direct creditor of the Borrower). The rights provided by this Section are in addition to all other rights of set-off and banker's lien and all other rights and remedies which any Lender (or any such Participant, branch, subsidiary or affiliate) may otherwise have under this Agreement, any other Loan Document, at law or in equity, or otherwise, and nothing in this Agreement or any other Loan Document shall be deemed a waiver or prohibition of or restriction on the rights of set-off or bankers' lien of any such Person.

SECTION 9.11 Sharing of Collections.

The Lenders hereby agree among themselves that if any Lender shall receive (by voluntary payment, realization upon security, set-off or from any other source) any amount on account of the Loans, interest thereon, or any other Obligation contemplated by this Agreement or the other Loan Documents to be made by the Borrower pro rata to all Lenders (or pro rata to holders of Notes) in greater proportion than any such amount received by any other applicable Lender, then the Lender receiving such proportionately greater payment shall notify each other Lender and the Administrative Agent of such receipt, and equitable adjustment will be made in the manner stated in this
Section 9.11 so that, in effect, all such excess amounts will be shared ratably among all of the applicable Lenders. The Lender receiving such excess amount shall purchase (which it shall be deemed to have done simultaneously upon the receipt of such excess amount) for cash from the other applicable Lenders a participation in the applicable Obligations owed to such other Lenders in such amount as shall result in a ratable sharing by all applicable Lenders of such excess amount (and to such extent the receiving Lender shall be a Participant). If all or any portion of such excess amount is thereafter recovered from the Lender making such purchase, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by Law to be paid by the Lender making such purchase. The Borrower hereby consents to and confirms the foregoing arrangements. Each Participant shall be bound by this Section as fully as if it were a Lender hereunder.

SECTION 9.12 Successors and Assigns; Participations; Assignments.

(a) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, all future holders of the Notes, the Agents and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights hereunder or interests herein without the prior written consent of all the Lenders and the Administrative Agent, and any purported assignment without such consent shall be void.

(b) Participations. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time sell participations to one or more commercial banks or other Persons (each a "Participant") in all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of its Commitment and the Loans owing to it and any Note held by it); provided, that
(i) any such Lender's obligations under this Agreement and the other Loan Documents shall remain unchanged,

(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,

(iii) the parties hereto shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and each of the other Loan Documents,

(iv) such Participant shall be bound by the provisions of
Section 9.11, and

(v) no Participant (unless such Participant is an Affiliate of such Lender, or is itself a Lender) shall be entitled to require such Lender to take or refrain from taking action under this Agreement or under any other Loan Document, except that such Lender may agree with such Participant that such Lender will not, without such Participant's consent, take any action, or consent to the taking of any action, of the type described in Section 9.01(a), (b) or (c).

The Borrower agrees that any such Participant shall be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.04 with respect to its participation in the Commitments and the Loans outstanding from time to time; provided, that no such Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred to such Participant had no such transfer occurred.

(c) Assignments. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time assign all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or any portion of its Commitment and Loans owing to it and any Note held by it) to any Lender, any Affiliate of a Lender or to one or more additional commercial banks or other Persons (each a "Purchasing Lender"); provided, that

-67-

(i) any such assignment to a Purchasing Lender which is not a Lender or an affiliate of a Lender shall be made only with the consent (which in each case shall not be unreasonably withheld) of the Borrower (so long as no Default or Event of Default shall have occurred and be continuing) and the Administrative Agent;

(ii) if a Lender makes such an assignment of less than all of its then remaining rights and obligations under this Agreement and the other Loan Documents, such transferor Lender shall retain, after such assignment, a minimum principal amount of $10,000,000 of the Commitments and Loans then outstanding, and such assignment, unless made to an assignee who is a Lender hereunder prior to such assignment, shall be in a minimum principal amount of $10,000,000 of the Commitments and Loans then outstanding;

(iii) each such assignment shall be of a constant, and not a varying, percentage of the Commitment of the transferor Lender and of all of the transferor Lender's rights and obligations under this Agreement and the other Loan Documents; and

(iv) each such assignment shall be made pursuant to an Assignment and Acceptance.

In order to effect any such assignment, the transferor Lender and the Purchasing Lender shall execute and deliver to the Administrative Agent a duly completed Assignment and Acceptance (including the consents required by clause (i) of the preceding sentence) with respect to such assignment, together with any Note or Notes subject to such assignment and a processing and recording fee of $3,500; and, upon receipt thereof, the Administrative Agent shall accept such Assignment and Acceptance. Upon receipt of notice from the transferor Lender that it has received the consideration described in the Assignment and Acceptance, the Administrative Agent shall record such acceptance in the Register. Upon such execution, delivery, acceptance and recording, from and after the close of business at the Administrative Agent's Principal Office on the settlement date specified in such Assignment and Acceptance:

(x) the Purchasing Lender shall be a party hereto and, to the extent provided in such Assignment and Acceptance, shall have the rights and obligations of a Lender hereunder, and

(y) the transferor Lender thereunder shall be released from its obligations under this Agreement to the extent so transferred (and, in the case of an Assignment and Acceptance covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party to this Agreement) from and after the settlement date.

On or prior to the settlement date specified in an Assignment and Acceptance, the Borrower, at its expense, shall execute and deliver to the Administrative Agent (for delivery to the Purchasing Lender) new Notes evidencing such Purchasing Lender's assigned Commitment or Loans and (for delivery to the transferor Lender) replacement Notes in the principal amount of the Loans or Commitment retained by the transferor Lender (such Notes to be in exchange for, but not in payment of, those Notes then held by such transferor Lender). Each such Note shall be dated the

-68-

date and be substantially in the form of the predecessor Note. The Administrative Agent shall mark the predecessor Notes "exchanged" and deliver them to the Borrower. Accrued interest and accrued fees shall be paid to the Purchasing Lender at the same time or times provided in the predecessor Notes and this Agreement.

(d) Register. The Administrative Agent shall maintain at its office a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive absent manifest error and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of the Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Financial and Other Information. The Borrower authorizes the Administrative Agent and each Lender to disclose to any Participant or Purchasing Lender (each, a "transferee") and any prospective transferee any and all financial and other information in such Person's possession concerning the Borrower and its Subsidiaries and Affiliates which has been or may be delivered to such Person by or on behalf of the Borrower in connection with this Agreement or any other Loan Document or such Person's credit evaluation of the Borrower and its Subsidiaries and Affiliates.

(f) Assignments to Federal Reserve Bank. Any Lender may at any time assign all or any portion of its rights under this Agreement, including without limitation any Loans owing to it, and any Note held by it, to a Federal Reserve Bank. No such assignment shall relieve the transferor Lender from its obligations hereunder.

(g) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC") the option to fund all or any part

of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to the terms hereof. The funding of a Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the Granting Lender to the same extent, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. Notwithstanding anything to the contrary contained in this Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. 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.

Any Party rendered unable to fulfill any of its obligations by reason of an Uncontrollable Force shall give prompt notice of such fact and shall exercise due diligence, as provided above, to remove such inability within a reasonable time period. If oral notice is provided, it shall be promptly followed by written notice.
Notwithstanding the "due diligence" obligations or obligations to remove or remedy the causes set forth in the foregoing paragraph (which do not apply to this paragraph except as specified below), where the entity providing transmission services for transactions under any Service Schedule interrupts such transmission service, the interruption in transmission service shall be considered an Uncontrollable Force under this Section 10 only in the following two sets of circumstances:
(1) An interruption in transmission service shall be considered an Uncontrollable Force if (a) the Parties agreed on a transmission path for that transaction at the time the transaction under this Agreement was entered into by the Parties' thereto, (b) firm transmission involving that transmission path was obtained pursuant to a transmission tariff or contract to effectuate the transaction under the applicable Service Schedule, and (c) the entity providing transmission service curtailed or interrupted such firm transmission pursuant to the applicable transmission tariff or contract;

(2) if the Parties did not agree on the transmission path for a transaction at the time the transaction was entered into, an interruption in transmission service shall be

considered an Uncontrollable Force only if (a) the Party contracting for transmission services shall have made arrangements with the entity providing transmission service for firm transmission to effectuate the transaction under the applicable Service Schedule, (b) the entity providing transmission service curtailed or interrupted such transmission service due to an event of Uncontrollable Forces or provision of like effect, and (c) the Party which contracted for such firm transmission services could not obtain alternate energy at the delivery point, alternate transmission services, or alternate means of delivering energy after exercising due diligence.
No Party shall be relieved by operation of this Section 10 of any liability to pay for power delivered to the Purchaser or to make payments then due or which the Party is obligated to make with respect to performance which occurred prior to the Uncontrollable Force.

                           this Section 21.3 are a reasonable estimate of loss
                           and not a penalty, and represent the sole and

                           the Non-Performing Party shall pay the full amount
                           of the damages as required by Section 9 of this
                           Agreement to the Performing Party.  After informal
                           dispute resolution as required by Section 34.1, any
                           remaining dispute involving the calculation of the
                           damages shall be referred to binding dispute
                           resolution as provided by Section 34.2 of this

                           Non-Performing Party, such refunds shall be

22.2 REMEDIES FOR EVENTS OF DEFAULT If an Event of Default occurs, the Non-Defaulting Party shall possess the right to terminate all transactions between the Parties under this Agreement upon written notice (by facsimile or other reasonable means) to the Defaulting Party, such notice of termination to be effective immediately upon receipt. If the Non-Defaulting Party fails to exercise this right of termination within thirty (30) days following the time when the Event of Default becomes known (or more than thirty days if the Non-Defaulting and Defaulting Parties agree to an extension), then such right of termination shall no longer be available to the Non-Defaulting Party as a remedy for the Event(s) of Default. The Non-Defaulting Party terminating transaction(s) under this Section 22.2 may do so without making a filing at FERC. Upon termination, the Non-Defaulting Party shall liquidate all transactions as soon as practicable, provided that in no event will the Non-Defaulting Party be allowed to liquidate Service Schedule A transactions. The payment associated with termination ("Termination Payment") shall be calculated in accordance with this Section 22.2 and Section
22.3. The Termination Payment shall be the sole and exclusive remedy for the Non-Defaulting Party for each terminated transaction ("Terminated Transaction") for the time period beginning at the time notice of termination under this Section

                  22 is received. Prior to receipt

of such notice of termination by the Defaulting Party, the Non-Defaulting Party may exercise any remedies available to it under Section 21.3 of this Agreement or Confirmation Agreement(s), and any other remedies available to it at law or otherwise.
Upon termination, the Non-Defaulting Party may withhold any payments it owes the Defaulting Party for any obligations incurred prior to termination under this Agreement or Confirmation Agreement(s) until the Defaulting Party pays the Termination Payment to the Non-Defaulting Party. The Non-Defaulting Party shall possess the right to set-off the amount due it under this Section 22 by any such payments due the Defaulting Party as provided in Section 22.3(d).
22.3 LIQUIDATION CALCULATION OPTIONS The Non-Defaulting Party shall calculate the Termination Payment as follows:
(a) The Gains and Losses shall be determined by comparing the value of the remaining term, transaction quantities, and transaction prices under each Terminated Transaction had it not been terminated to the equivalent quantities and relevant market prices for the remaining term either quoted by a bona fide third-party offer or which are reasonably expected to be available in the market under a replacement contract for each Terminated Transaction. To ascertain the market prices of a replacement contract, the Non-Defaulting Party may consider, among other valuations, quotations

(1) The First Party has knowledge that the Second Party (or its Guarantor if applicable) are failing to perform or defaulting under other contracts.
(2) The Second Party has exceeded any credit or trading limit set out in the Confirmation Agreement or other agreement between the Parties.

(4) Other material adverse changes in the Second Party's financial condition occur.
(5) Substantial changes in market prices which materially and adversely impact the Second Party's ability to perform under this Agreement or any Confirmation Agreement occur. If the Second Party fails to provide such reasonably satisfactory assurances of its ability to perform a transaction hereunder within three (3) Business Days of demand therefore, that will be considered an Event of Default under Section 22 of this Agreement and the First Party shall have the right to exercise any of the remedies provided for under

The Purchaser shall have five Business Days from date of receipt to respond to the confirmation. If the Purchaser does not respond within that time period, the Seller's written confirmation shall be considered as accepted and final except as provided in Section
32.5. If the Seller fails to provide any required written confirmation within five Business Days, as described above, then the Purchaser may submit a written confirmation to the Seller. The Purchaser shall submit such written confirmation within five Business Days after the deadline for submitting a written confirmation applicable to the Seller as set forth above has expired. If the Seller fails to respond to Purchaser's confirmation within five Business Days, then the Purchaser's written confirmation shall be considered as accepted and final except as provided in Section 32.5. Notwithstanding the foregoing, any failure of the Seller or the Purchaser to provide written confirmation of the transaction shall not invalidate any oral agreement of the Parties. Nor shall any oral agreement of the Parties be

                  considered invalidated

32.2 The Parties agree not to contest, or assert any defense with respect to, the validity or enforceability of any agreement to the terms concerning a specific transaction(s), on the basis that documentation of such terms fails to comply with the requirements of any statute that agreements be written or signed. Each Party consents to the recording by the other Party, without any further notice, of telephone conversations between representatives of the Parties, which contain agreements to or discussion concerning the terms of a specific transaction(s). All such recordings may be introduced and admitted into evidence for the purpose of proving agreements to terms, and any objection to such introduction or admission for such purpose is hereby expressly waived. The terms documented hereunder, whether stated in a written document or a recording, are intended by the Parties as a final expression of their agreement with respect to such terms as are included therein and may not be contradicted by evidence of any prior agreement, but may be supplemented by course of dealing, performance, usage of trade and evidence of consistent additional mutually agreed-upon terms.
32.3 For individual transactions under the Service Schedules, the Agreement as it may be modified or supplemented by a Confirmation Agreement shall bind the Parties and govern the transactions; provided, however, if the Parties to a transaction do not reach agreement on such modification or change to a term of the Agreement, or the Confirmation Agreement is not considered accepted and final pursuant to
Section 32.1, then the term or terms of the Agreement, which the Parties could not

32.5 When a Confirmation Agreement contains "non-standard confirmation provisions" which are provisions other than those set forth in paragraphs (a) 2 (l) of Exhibit C, those non-standard confirmation provisions shall not be deemed to be accepted pursuant to Section 32.1 unless agreed to: (i) orally, with that oral agreement recorded (provided that such oral agreement option only shall be available for transactions of less than one week); or (ii) in a writing executed by both Parties.
32.6 Other Products and Service Levels: The Parties may agree to use a product/service level defined by a different agreement (e.g., the California ISO tariff, the ERCOT agreement or the EEI agreement) for a particular transaction under this Agreement. Unless the Parties expressly state and agree that all the terms and conditions of such other agreement will apply to any such transaction, the transaction shall be subject to all the terms of this Agreement, except that (1) all service level/product definitions, (2) force majeure/uncontrollable force definitions, and (3) other terms as mutually agreed shall have the meaning

38.1 In the event the Parties intend that the price for a transaction is to be based on an index, exchange or any other kind of variable reference price (such price being a "Floating Price"), the Parties shall specify the "Floating Price" to be used to calculate the amounts in a Confirmation Agreement due Seller for that transaction.

The Parties shall negotiate in good faith to agree on a Floating Price (or a method for determining a Floating Price) for the affected Trading Day. If the Parties have not so agreed on or before the twelfth Business Day following the first Trading Day on which the Market Disruption Event occurred or existed, then the Floating Price shall be determined in good faith by the Parties based upon (1) quotes from Dealers in energy contracts; and/or (2) quotes from Brokers in energy contracts. Each Party may obtain up to a maximum of four quotes which must be provided to the other Party no later than twenty-two Business Days following the first Business Day on which the Market Disruption Event occurred or existed. These quotes shall reflect transacted prices. The Floating Price for the affected Trading Day shall equal a simple average of the quotes obtained and provided by the Parties consistent with the provisions of this Section 38.

"Determination Period" means each calendar month during the term of the relevant transaction; provided that if the term of the transaction is less than one calendar month the Determination Period shall be the term of the transaction. "Market Disruption Event" means, with respect to an index, any of the following events (the existence of which shall be determined in good faith by the Parties):
(a) the failure of the index to announce or publish information necessary for determining the Floating Price;
(b) the failure of trading to commence or the permanent discontinuation or material suspension of trading in the relevant options contract or commodity on the exchange or market acting as the index; (c) the temporary or permanent discontinuance or unavailability of the index; (d) the temporary or permanent closing of any exchange acting as the index; or (e) a material change in the formula for or the method of determining the Floating Price.

39.2 Unless otherwise stated in the amendment, all amendments shall apply only to new transactions entered into or agreed to on or after the effective date of the amendment. Preexisting agreements and transactions shall operate under the version of the WSPP Agreement effective at the time of the agreement for the transaction unless the Parties to a transaction or transactions mutually agree otherwise.
39.3 An agreement modifying this Agreement or a Confirmation Agreement for a transaction needs no consideration to be binding.

Each Party that executes this Exhibit A to the Agreement agrees to net payments for transactions under WSPP Service Schedule A, B, and C with any other Party or Parties which also have agreed to net payments by executing a copy of this Exhibit A. The Party executing this Exhibit A shall indicate below when it desires that its agreement to net becomes effective. A Party agreeing to net under this Exhibit A shall comply with the provisions of Section 28.2 of the Agreement. Defined terms used herein are as defined in the WSPP Agreement. Netting shall be done in accordance with the following provision:
If the Purchaser and Seller are each required to pay an amount on the payment due date in the same month for transactions under the Agreement or Confirmation Agreement, then such amounts with respect to each Party will be aggregated and the Parties will discharge their obligations to pay through netting, in which case the Party owing the greater aggregate amount will pay to the other party the difference between the amounts owed consistent with the payment times in Section 9.2 of the Agreement, unless the Parties have otherwise agreed to a different payment time as allowed by the Agreement. Each Party reserves to itself all rights, set-offs, counterclaims and other remedies and/or defenses to which it is or may be entitled, arising from or out of the Agreement.

WITNESSETH:

WHEREAS, [___________________] (the "Company") may enter into transactions involving power sales under the Western Systems Power Pool ("WSPP Agreement") and related confirmation agreements1 (collectively "Agreements") with [Company Name] ("Guaranteed Party"); and

WHEREAS, Guarantor will directly or indirectly benefit from the Agreements.

NOW THEREFORE, in consideration of the Guaranteed Party agreeing to conduct business with Company, Guarantor hereby covenants and agrees as follows:

1. GUARANTY. Subject to the provisions hereof, Guarantor hereby irrevocably and unconditionally guarantees the timely payment when due of the obligations of Company (the "Obligations") to the Guaranteed Party in accordance with the Agreements. If Company fails to pay any Obligations, Guarantor shall promptly pay to the Guaranteed Party no later than the next Business Day (as defined in the WSPP Agreement), after notification, the amount due in the same currency and manner provided for in the Agreements. This Guarantee shall constitute a guarantee of payment and not of collection. Guarantor shall have no right of subrogation with respect to any payments it makes under this Guarantee until all of the Obligations of Company to the Guaranteed Party are paid in full. The liability of Guarantor under the Guarantee shall be subject to the following:

(a) Guarantor's liability hereunder shall be and is specifically limited to payments expressly required to be made in accordance with the Agreements (even if such payments are deemed to be damages) and, except to the extent specifically provided in the Agreements, in no event shall Guarantor be subject hereunder to consequential, exemplary, equitable, loss of profits, punitive, tort, or any other even if such fees together with the payments

(b) The aggregate liability of the Guarantor shall not exceed
[_____] Million U.S. Dollars [___________].

2. DEMANDS AND NOTICE. If Company fails or refuses to pay any Obligations, the Guaranteed Party may make a demand upon Guarantor (hereinafter referred to as a "Payment Demand"). A Payment Demand shall be in writing and shall reasonably and briefly specify in what manner and what amount Company has failed to pay and an explanation of why such payment is due, with a specific statement that the Guaranteed Party is calling upon Guarantor to pay under this Guarantee. A Payment Demand satisfying the foregoing requirements shall be deemed sufficient notice to Guarantor that it must pay the Obligations. A single written Payment Demand shall be effective as to any specific default during the continuance of such default, until Company or Guarantor has cured such default, and additional Payment Demands concerning such default shall not be required until such default is cured.

3. REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants that:

(a) it is a corporation duly organized and validly existing under the laws of the State of [_____________] and has the corporate power and authority to execute, deliver and carry out the terms and provisions of this Guarantee;

(b) no authorization, approval, consent or order of, or registration or filing with, any court or other governmental body having jurisdiction over Guarantor is required on the part of Guarantor for the execution and delivery of this Guarantee; and

(c) this Guarantee constitutes a valid and legally binding agreement of Guarantor enforceable against Guarantor in accordance with its terms, except as the enforceability of this Guarantee may be limited by the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally and by general principles of equity.

4. EFFECT OF BANKRUPTCY BY COMPANY. The Guarantor's obligation to pay under this Guarantee shall not be affected in any way by the institution with respect to the Company of a bankruptcy, reorganization, moratorium or similar insolvency proceeding or other relief under any bankruptcy or insolvency law affecting creditor's rights or a petition for the Company's winding-up or liquidation.

5. AMENDMENT. No term or provision of this Guarantee shall be amended, modified, altered, waived, or supplemented except in a writing signed by the Guarantor and Guaranteed Party hereto.

6. WAIVERS. Guarantor hereby waives (a) notice of acceptance of this Guarantee; (b) presentment and demand concerning the liabilities of Guarantor, this except as expressly hereinabove set forth; and (c) any right to require that any action or proceeding be brought against Company or any other person, or except as expressly hereinabove set forth, to require that the Guaranteed Party seek enforcement of any performance against Company or any other person, prior to any action against Guarantor under the terms hereof.

Except as to applicable statutes of limitation, no delay of the Guaranteed Party in the exercise of, or failure to exercise, any rights hereunder shall operate as a waiver of such rights, a waiver of any other rights or a release of Guarantor from any obligations hereunder.

Guarantor consents to the renewal, compromise, extension, acceleration or other changes in the time of payment of or other changes in the terms of the Obligations, or any part thereof or any changes or modifications to the terms of the Agreements.

Guarantor may terminate this Guarantee by providing written notice of such termination to the Guaranteed Party and upon the effectiveness of such termination, Guarantor shall have no further liability hereunder, except as provided in the last sentence of this paragraph. No such termination shall be effective until fifteen (15) Business Days after receipt by the Guaranteed Party of such termination notice.

                             UNIT COMMITMENT SERVICE
                             -----------------------
B-1      PARTIES:
         This Service Schedule is agreed upon as part of this Agreement by the
         Parties.

B-2      PURPOSE:
         The purpose of this Service Schedule is to define additional specific
         procedures, terms, and conditions for requesting and providing Unit
         Commitment Service.

B-3      TERMS:

         B-3.1    A Party may schedule Unit Commitment Service from another
                  Party by mutual agreement; provided, however, that each Party
                  shall be the sole judge as to the extent to and the conditions
                  under which it is willing to provide or receive such service
                  hereunder consistent with statutory requirements and
                  contractual commitments including the Agreement and any
                  applicable Confirmation Agreement. Once an agreement is
                  reached, then the obligation for Unit Commitment Service
                  becomes a firm commitment, for both Parties, for the agreed
                  capacity and terms.

         B-3.2    Unless otherwise mutually agreed by the Parties involved in a
                  Unit Commitment Service transaction, the terms set forth in
                  this Service Schedule B shall govern such transaction.

B-3.4    Purchasers shall arrange purchases directly with Sellers.

B-3.5    The price for Unit Commitment Service shall be mutually agreed
         to in advance between Seller and Purchaser and shall not be
         subject to the rate caps specified in Section B-3.6 in either
         of the following two circumstances:
         (1)      where the Seller is a FERC regulated public utility
                  and that Seller has been authorized to sell power
                  like that provided for under this Service Schedule at
                  market-based rates; or
         (2)      where the Seller is not a FERC regulated public
                  utility. A Party is a FERC regulated public utility
                  if it is a "public utility" as defined in Section
                  201(e) of the Federal Power Act, 16 U.S.C. [sect].
                  824(e).

         The total demand charge revenues in any consecutive seven-day
         period shall not exceed the product of the weekly rate and the

         The Seller's forecasted Incremental Cost discussed above also
         may include any transmission and/or ancillary service costs
         associated with the sale, including the cost of any
         transmission and/or ancillary services that the Seller must
         take on its own system. Any such transmission and/or ancillary
         service charges shall be separately identified by the Seller
         to the Purchaser. The transmission and ancillary service rate
         ceilings shall be available through the WSPP's Hub or

         modified by the Purchaser with not less than a thirty (30)
         minute notice before the hour in which the change is to take
         place, unless otherwise mutually agreed or unforeseen system
         operating conditions occur.
B-3.9    Unit Commitment Service is intended to have assured
         availability; however, scheduled energy deliveries may be
         interrupted or curtailed as follows:
         (a)      By the Seller by giving proper recall notice to the
                  Purchaser if the Seller and the Purchaser have
                  mutually agreed to recall provisions,
         (b)      By the  Seller  when all or a portion of the  output
                  of the unit is  unavailable,  by an amount in

C-1      PARTIES:
         This Service Schedule is agreed upon as a part of this Agreement by the
         Parties.

C-2      PURPOSE:
         The purpose of this Service Schedule is to define additional specific
         procedures, terms, and conditions for requesting and providing Firm
         Capacity/Energy Sale or Exchange Service.

C-3      TERMS:

         C-3.1    A Party may schedule Firm Capacity/Energy Sale or Exchange
                  Service from another Party by mutual agreement; provided,
                  however, that each Party shall be the sole judge as to the
                  extent to and the conditions under which it is willing to
                  provide or receive such service hereunder consistent with
                  statutory requirements and contractual commitments including
                  the Agreement and any applicable Confirmation Agreement. Once
                  an agreement is reached, then the obligation for Firm
                  Capacity/Energy Sale or Exchange Service becomes a firm
                  commitment, for both Parties, for the agreed service and
                  terms.

         C-3.2    Unless otherwise agreed between the Purchaser and the Seller,
                  all transactions shall be prescheduled, subject to any
                  conditions agreed to by schedulers.

         C-3.3    Firm capacity transactions shall include buying, selling, or
                  exchanging capacity between Parties with or without associated
                  energy. Firm capacity is deemed a capacity sale from the
                  Seller's resources and backed by the Seller's

                  Purchaser and shall not be subject to the rate caps specified
                  in Section C-3.7 in either of the following two circumstances:
                  (1)      where the Seller is a FERC regulated public utility
                           and that Seller has been authorized to sell power
                           like that provided for under this Service Schedule at
                           market-based rates; or
                  (2)      where the Seller is not a FERC regulated public
                           utility.
                  A Party is a FERC regulated public utility if it is a "public
                  utility" as defined in Section 201(e) of the Federal Power
                  Act, 16 U.S.C. [sect]. 824(e).

                  exceed the Seller's forecasted Incremental Cost plus up to:
                  $7.32/kW/month; $1.68/kW/week; 33.78[cent]/kW/day; 14.07

Exchange ratios among such Parties shall be as mutually agreed between the Purchaser and the Seller, but shall not exceed the ratio of 1.5 to 1.0. The Seller's forecasted Incremental Cost discussed above also may include any transmission and/or ancillary service costs associated with the sale, including the cost of any transmission and/or ancillary services that the Seller must take on its own system. Any such transmission and/or ancillary service charges shall be separately identified by the Seller to the Purchaser for transactions under this Schedule including exchanges. The transmission and ancillary service rate ceiling shall be available through the WSPP's Hub or homepage. Any such transmission service (and ancillary services provided in conjunction with such transmission service) by Seller shall be provided pursuant to any applicable transmission tariff or agreement, and the rates therefore shall be consistent with such tariff or agreement.

C-3.8 Firm Capacity/Energy Sale or Exchange Service shall be interruptible only if the interruption is: (a) within the recall time or allowed by other applicable provisions governing interruptions of service under this Service Schedule mutually agreed to by the Seller and the Purchaser,
(b) due to an Uncontrollable Force as provided in Section 10 of this Agreement; or (c) where applicable, to meet Seller's public utility or statutory obligations to its customers. If service under this Service Schedule is interrupted under
Section C-3.8(a) or (b), neither Seller nor Purchaser shall be obligated to pay any damages under this Agreement or Confirmation Agreement. If service under this Service Schedule is interrupted for any reason

5.0 Transmission Customer understands that Transmission Provider is experiencing high load growth and that Transmission Provider's obligation to serve Native Load Customers is projected to increase significantly in the future.

If adequate capacity is not available, Transmission Customer's right to renew this Agreement is subject to Sections 19-21 of the Transmission Provider's Tariff and also is subject to Transmission Customer's agreement to pay any costs of Network Upgrades that Transmission Provider is authorized to charge to Transmission Customer in accordance with Commission policy.

6.0 The Transmission Provider agrees to provide and the Transmission Customer agrees to take and pay for Firm Point-To-Point Transmission Service in accordance with the provisions of Part II of the Tariff and this Service Agreement.

SECTION 2.01 The Commitments.

Subject to the terms and conditions set forth herein, each Lender agrees to make loans (each such loan, a "Revolving Loan") to the Borrower from time to time on any Business Day during the Availability Period in an aggregate principal amount that will not result in (i) such Lender's Revolving Credit Exposure (after giving effect to such Revolving Loans)

-16-

exceeding such Lender's Commitment or (ii) the sum of the Revolving Credit Exposures of all Lenders exceeding the total Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans.

SECTION 2.02 Loans and Borrowings.

(a) Obligations of Lenders. Each Revolving Loan shall be made as part of a Borrowing consisting of Loans of the same Type made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder. The Commitments of the Lenders are several and no Lender shall be responsible for any other Lender's failure to make Loans as required.

(b) Type of Loans. Subject to Section 2.11, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans. Each Lender may, at its option, make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) Minimum Amounts; Limitation on Number of Borrowings. Each Revolving Borrowing (whether an ABR Borrowing or a Eurodollar Borrowing) shall be in an aggregate amount equal to $5,000,000 or a multiple of $1,000,000 in excess thereof; provided that an ABR Borrowing may be made in an aggregate amount that is equal to the entire unused balance of the total Commitments. The Borrower may thereafter, upon irrevocable notice to the Administrative Agent in accordance with Section 2.05(b), (i) elect, as of any Business Day, in the case of ABR Loans, to convert any such ABR Loans or any part thereof, in an aggregate amount equal to $5,000,000 or a multiple of $1,000,000 in excess thereof, into Eurodollar Loans, and (ii) elect, as of the last day of the applicable Interest Period, to continue any Eurodollar Loans having Interest Periods expiring on such day or any part thereof in an aggregate amount of $5,000,000 or a multiple of $1,000,000 in excess thereof; provided that, if at any time the aggregate amount of Eurodollar Loans in respect of any Borrowing is reduced by payment, prepayment or conversion of part thereof to be less than $5,000,000, such Eurodollar Loans shall automatically convert into ABR Loans. Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of five Eurodollar Borrowings outstanding.

(d) Maximum Duration of Interest Periods. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Borrowing if the Interest Period requested with respect thereto would end after the Revolving Termination Date.

SECTION 2.03 Requests for Revolving Borrowings.

To request a Revolving Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Revolving Borrowing, not later than 12:00 noon, New York, New York time, three Business Days before the date of the

-17-

proposed Borrowing, or (b) in the case of an ABR Borrowing, not later than 12:00 noon, New York, New York time, one Business Day before the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in the form attached hereto as Exhibit B and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with
Section 2.02:

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;
(iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term "Interest Period"; and

(v) the location and number of the Borrower's account to which funds are to be disbursed, which shall comply with the requirements of Section 2.04.

If no election as to the Type of Revolving Borrowing is specified, then the requested Revolving Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any Eurodollar Revolving Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month's duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender's Loan to be made as part of the requested Borrowing.

SECTION 2.04 Funding of Borrowings.

(a) Funding by Lenders. No later than 12:00 noon, New York, New York time, on the date specified in each Borrowing Request, each Lender will make available its Applicable Percentage of each Revolving Borrowing requested to be made on such date, in Dollars and in immediately available funds at the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with Union Bank of California, N.A. at the Principal Office and designated by the Borrower in the applicable Borrowing Request.

(b) Presumption by the Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative

-18-

Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the Federal Funds Effective Rate or (ii) in the case of the Borrower, the interest rate applicable to the Loans of such Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing.

SECTION 2.05 Interest Elections.

(a) Elections by the Borrower for Borrowings. Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section but subject to Section 2.02. Once Loans have been made pursuant to a Borrowing, the Borrower may elect to convert or continue different portions of such Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) Notice of Elections. To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) of this paragraph shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period".

-19-

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration.

(d) Notice by the Administrative Agent to Lenders. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing.

(e) Failure to Elect; Events of Default. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.06 Termination, Reduction and Extension of Commitments.

(a) Scheduled Termination. Unless previously terminated, the Commitments shall terminate on the Revolving Termination Date.

Section 2.08, the sum of the total Revolving Credit Exposures would exceed the total Commitments.

(c) Notice of Voluntary Termination or Reduction. The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

(d) Effect of Termination or Reduction. Any termination or reduction of the Commitments shall be permanent. Except as otherwise provided in
Section 2.06(e)(i), each reduction of the Commitments shall be made ratably among the Lenders in accordance with their Applicable Percentages.

Any Lender which shall fail to so notify the Administrative Agent within such period shall be deemed to have declined to extend the Revolving Termination Date. If Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect agree to such extension by notice to the Administrative Agent, then (A) subject to clause (iii) below, the Revolving Termination Date shall be extended for an additional 364 days with respect to the Commitments of the Lenders so agreeing, and (B) subject to Section 2.06(f) hereof, the Commitment of each Lender not so agreeing shall expire on the then expiring Revolving Termination Date and the Borrower shall pay or prepay on such day without premium or penalty all principal of such Lender's Loans together with accrued interest thereon and all accrued facility fees and other amounts payable to such Lender hereunder (including, without limitation, amounts payable pursuant to Section 2.13 hereof as a result of such payment or prepayment); provided, however, that

(x) if Lenders having Commitments totaling an amount equal to at least 51% of the aggregate amount of the Commitments then in effect do not agree as contemplated by
Section 2.06(e)(i), then the Revolving Termination Date shall not be extended pursuant to this Section 2.06(e) and the Commitments of all of the Lenders shall remain in effect until the Revolving Termination Date except as otherwise provided in this Agreement; and

(y) the Borrower may not request any extension of the Revolving Termination Date pursuant to this Section 2.06(e)(i) more frequently than once in any calendar year.

(iii) It shall be a condition precedent to any extension of the Revolving Termination Date that: (a) on the date of such extension no Default or Event of Default shall have occurred and be continuing;
(b) the representations and warranties made by the Borrower in Article III shall be true and correct on and as of the date of such extension (or if any such

Each request for an extension of the Revolving Termination Date pursuant to Section 2.06(e) shall constitute a certification by the Borrower to the effect set forth in the preceding sentence (both as of the date of such request and, unless the Borrower notifies the Administrative Agent prior to the date of such extension, as of the date of such extension).

(f) Substitute Lenders. In the event any Lender does not agree to any extension by the date provided pursuant to Section 2.06(e) hereof, then, unless a Default or an Event of Default shall have occurred and be continuing, the Borrower may, not later than 10 days following the expiration of the Extension Request Period, designate one or more other banks (each such bank being herein called a "Substitute Lender"), which may include any of the Lenders, acceptable to the Administrative Agent (which acceptance will not be unreasonably withheld), to assume such non-consenting Lender's Commitment hereunder and to purchase, on or before the date such Lender's Loans would otherwise be required to be paid or prepaid hereunder, the Loans and Notes of such Lender and such Lender's rights hereunder in respect thereof, without recourse to or representation or warranty by, or expense to, such Lender. In such event, the purchase price shall be equal to the outstanding principal amount of the Loans and Notes payable to such Lender plus any accrued but unpaid interest on such Loans and Notes and accrued but unpaid facility fees in respect of such Lender's Commitment. Upon such assumption and purchase and the receipt by such Lender of any other amounts payable to it by the Borrower under this Agreement, and subject to the execution and delivery to the Administrative Agent and such Lender by the Substitute Lender of documentation reasonably satisfactory to the Administrative Agent and such Lender pursuant to which such Substitute Lender shall assume the obligations of such original Lender under this Agreement in respect of its Loans, Notes and Commitment and agree to become a "Lender" hereunder (if not already a Lender) to the extent of the Commitments, Loans and Notes assumed and purchased, the Substitute Lender shall succeed to the rights, obligations and benefits of such Lender hereunder in such respect (except for such rights, obligations and benefits of the Lender as have accrued (other than principal, accrued interest or facility fees) or are required to be performed by it on or prior to the date of such assumption and purchase) (and such Lender shall be released from its Commitment except for any liability arising or relating to any event occurring prior to the date of such assumption and purchase) and the Substitute Lender shall be deemed to have agreed to the relevant extension of the Revolving Termination Date and, anything in Section 2.06(e) to the contrary notwithstanding, whether such extension is effective shall be determined accordingly; provided that following any such assumption and purchase the Commitments of each Substitute Lender (including any Commitments theretofore held by it) shall be not less than $10,000,000.

SECTION 2.07 Repayment of Loans; Evidence of Debt.

(a) Repayment. The Borrower hereby unconditionally promises to pay to the Administrative Agent for account of the Lenders the outstanding principal amount of the Revolving Loans on the Revolving Termination Date.

(b) Manner of Payment. Prior to any repayment or prepayment of any Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings to be paid and shall notify the Administrative Agent by telephone (confirmed by telecopy) of such selection not later than 12:00 noon, New York, New York time, three Business Days before the scheduled date of such repayment or prepayment; provided that each repayment or prepayment of Borrowings shall be applied to repay or prepay any outstanding ABR Borrowings before any other Borrowings. If the Borrower fails to make a timely selection of the Borrowing or Borrowings to be repaid or prepaid, such payment shall be applied, first, to pay any outstanding ABR Borrowings and, second, to other Borrowings in the order of the remaining duration of their respective Interest Periods (the Borrowing with the shortest remaining Interest Period to be repaid first). Each payment of a Revolving Borrowing shall be applied ratably to the Loans included in such Borrowing.

(c) Maintenance of Loan Accounts by Lenders. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(d) Maintenance of Loan Accounts by the Administrative Agent.
The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder and the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

(e) Effect of Entries. The entries made in the accounts maintained pursuant to paragraphs (c) and (d) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(f) Notes. Any Lender may request that Loans made by it be evidenced by a promissory note (each a "Note") in substantially the form of

Exhibit C. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in the form of Exhibit C. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 9.12) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

SECTION 2.08 Prepayment of Loans.

(a) Optional Prepayments Right to Prepay Borrowings. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section.

(i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York, New York time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York, New York time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by
Section 2.06(c), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(c). Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an aggregate principal amount equal to $5,000,000 and a multiple of $1,000,000 in excess thereof; provided that if any prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Revolving Loans made pursuant to such Borrowing to an amount less than $5,000,000, such outstanding Loans shall immediately be converted into ABR Loans. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.10 and shall be made in the manner specified in this Section 2.08(b).

SECTION 2.09 Fees.

(a) Facility Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender a facility fee for the period from and including the Effective Date to but excluding the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated) computed at a rate per annum equal to the Applicable Rate on each Lender's daily average Commitment, such fee to be paid quarterly in arrears on each Quarterly Date and on the Revolving Termination Date (or such earlier date on which the total Commitments shall have been terminated). The facility fee shall be calculated on the basis of the actual number of days elapsed in a year of 360 days.

(b) Fee Letter. The Borrower agrees to pay to the Administrative Agent, for the account of the Administrative Agent and the Co-Lead Arrangers, the fees agreed to by the Borrower, NPC, Sierra Pacific Resources, the Administrative Agent and the Co-Lead Arrangers pursuant to that certain letter agreement, dated the date hereof (the "Fee Letter"), or as otherwise agreed from time to time.

-24-

SECTION 2.10 Interest.

(a) ABR Loans. The Loans comprising each ABR Revolving Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate.

(b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Default Interest. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% above the higher of (A) the rate otherwise applicable to such Loan as provided above and (B) the rate applicable to ABR Loans as provided in paragraph (a) of this Section, or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d) Payment of Interest. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (x) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (y) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the Revolving Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (z) in the event of any conversion of any Eurodollar Borrowing prior to the end of the current Interest Period therefor, accrued interest on such Borrowing shall be payable on the effective date of such conversion.

(e) Computation. All interest hereunder shall be computed on the basis of a year of 360 days, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive, absent manifest error.

SECTION 2.11 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent

-25-

notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Revolving Borrowing.

SECTION 2.12 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or its Parent (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or its Parent or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender or its Parent of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of its Parent as a consequence of this Agreement or the Loans made by such Lender to a level below that which such Lender or its Parent could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of its Parent with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its Parent for any such reduction suffered.

(c) Certificates from Lenders. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its Parent, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's right to demand such compensation.

SECTION 2.13 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow,

-26-

convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable under Section 2.08(b) and is revoked in accordance herewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.16, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an Affiliate of such Lender) for dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.14 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, each Co-Lead Arranger, the Syndication Agent or each Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable Law.

(b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Co-Lead Arranger, the Syndication Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Co-Lead Arranger, the Syndication Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to

-27-

the Borrower by a Lender, a Co-Lead Arranger, the Syndication Agent or the Administrative Agent (on its own behalf or on behalf of a Lender, a Co-Lead Arranger or the Syndication Agent) shall be conclusive, absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable Law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without withholding or at a reduced rate.

SECTION 2.15 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.12, 2.13 or 2.14, or otherwise) prior to 1:00 PM, New York, New York time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any such date shall be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its Principal Office and to such account at its Principal Office as the Administrative Agent shall specify to the Borrower, except that payments pursuant to Sections 2.12, 2.13, 2.14 and 9.04 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Revolving Borrowing shall be made from the Lenders, each payment of facility fees under Section 2.09 shall be made for the account of the Lenders, and each termination or reduction of

-28-

the amount of the Commitments under Section 2.06 shall be applied to the respective Commitments of the Lenders, pro rata according to the amounts of their respective Commitments; (ii) each Borrowing shall be allocated pro rata among the Lenders according to the amounts of their respective Commitments (in the case of the making of Revolving Loans) or their respective Loans (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders.

(d) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon then due than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(e) Presumptions of Payment. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate.

(f) Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or 2.15(e), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such

-29-

Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.16 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 2.12, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.12), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

matter be proved or established with respect to the Borrower or any Lender, such matter may be established by a certificate of the Borrower or such Lender, as the case may be, and the Administrative Agent may conclusively rely upon such certificate (unless other evidence with respect to such matter is specifically prescribed in this Agreement or another Loan Document).

(d) The Administrative Agent may fail or refuse to take any action unless it shall be indemnified to its satisfaction from time to time against any and all amounts, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature which may be imposed on, incurred by or asserted against the Administrative Agent by reason of taking or continuing to take any such action.

(e) The Administrative Agent may perform any of its duties under this Agreement or any other Loan Document by or through agents or attorneys-in-fact. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

(f) The Administrative Agent shall not be deemed to have any knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default, and stating that such notice is a "notice of default". If the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to each Lender.

SECTION 8.06 Lenders Not Relying on Administrative Agent or Other Lenders.

Each Lender acknowledges as follows:

(a) Neither the Administrative Agent nor any other Lender has made any representations or warranties to it, and no act taken hereafter by the Administrative Agent or any other Lender shall be deemed to constitute any representation or warranty by the Administrative Agent or such other Lender to it.

(b) It has, independently and without reliance upon the Administrative Agent or any other Lender, and based upon such documents and information as it has deemed appropriate, made its own credit and legal analysis and decision to enter into this Agreement and the other Loan Documents.

(c) It will, independently and without reliance upon the Administrative Agent or any other Lender, and based upon such documents and information as it shall deem appropriate at the time, make its own decisions to take or not take action under or in connection with this Agreement and the other Loan Documents.

SECTION 8.07 Indemnification.

Each Lender agrees to reimburse and indemnify the Administrative Agent and its directors, officers, employees and agents (to the extent not reimbursed by the Borrower and without limitation of the obligations of the Borrower to do so, in each case pursuant to the terms of this Agreement and the other Loan Documents), based on its Applicable Percentage, from and

-58-

against any and all amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements of any kind or nature (including, without limitation, the fees and disbursements of counsel for the Administrative Agent or such other Person in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not the Administrative Agent or such other Person shall be designated a party thereto) that may at any time be imposed on, incurred by or asserted against the Administrative Agent or such other Person as a result of, or arising out of, or in any way related to or by reason of, this Agreement, any other Loan Document, any transaction from time to time contemplated hereby or thereby, or any transaction financed in whole or in part or directly or indirectly with the proceeds of any Loan, provided that no Lender shall be liable for any portion of such amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements resulting solely from the gross negligence or willful misconduct of the Administrative Agent or such other Person, as finally determined by a court of competent jurisdiction. Payments under this Section 8.07 shall be due and payable on demand, and to the extent that any Lender fails to pay any such amount on demand, such amount shall bear interest for each day from the date of demand until paid (before and after judgment) at a rate per annum (calculated on the basis of a year of 360 days and actual days elapsed) which for each day shall be equal to the Federal Funds Effective Rate for such day.

SECTION 8.08 Administrative Agent in its Individual Capacity.

With respect to its Commitment and the Obligations owing to it, the Administrative Agent shall have the same rights and powers under this Agreement and each other Loan Document as any other Lender and may exercise the same as though it were not the Administrative Agent, and the terms "Lenders," "holders of Notes" and like terms shall include the Administrative Agent in its individual capacity as such. The Administrative Agent and its affiliates may, without liability to account, make loans to, accept deposits from, acquire debt or equity interests in, act as trustee under indentures of, and engage in any other business with, the Borrower and any stockholder, subsidiary or affiliate of the Borrower, as though the Administrative Agent were not the Administrative Agent hereunder.

SECTION 8.09 Holders of Notes.

The Administrative Agent may deem and treat the Lender which is payee of a Note as the owner and holder of such Note for all purposes hereof unless and until an Assignment and Acceptance with respect to the assignment or transfer thereof shall have been filed with the Administrative Agent in accordance with Section 9.12. Any authority, direction or consent of any Person who at the time of giving such authority, direction or consent is shown in the Register as being a Lender shall be conclusive and binding on each present and subsequent holder, transferee or assignee of any Note or Notes payable to such Lender or of any Note or Notes issued in exchange therefor.

SECTION 8.10 Successor Administrative Agent.

The Administrative Agent may resign at any time by giving 10 days' prior written notice thereof to the Lenders and the Borrower. The Administrative Agent may be removed by the Required Lenders at any time with or without cause by giving 10 days' prior written notice

-59-

thereof to the Administrative Agent, the other Lenders and the Borrower. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed and consented to, and shall have accepted such appointment, within 30 days after such notice of resignation or removal, then the retiring Administrative Agent, on behalf of the Lenders, may appoint a successor Administrative Agent. Each successor Administrative Agent shall be a commercial bank or trust company organized under the Laws of the United States of America or any State thereof and having a combined capital and surplus of at least $1,000,000,000. The appointment of any successor Administrative Agent at any time pursuant to this Section 8.10 shall be subject to the approval of the Borrower, provided that at such time there shall not have occurred and be continuing any Default or Event of Default, and provided further that the Borrower's consent to any such appointment shall not be unreasonably withheld. Upon the acceptance by a successor Administrative Agent of its appointment as Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the properties, rights, powers, privileges and duties of the former Administrative Agent without further act, deed or conveyance. Upon the effective date of resignation or removal of a retiring Administrative Agent, the Administrative Agent shall be discharged from its duties under this Agreement and the other Loan Documents, but the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted by it while it was Administrative Agent under this Agreement. If and for so long as no successor Administrative Agent shall have been appointed, then any notice or other communication required or permitted to be given by the Administrative Agent shall be sufficiently given if given by the Required Lenders, all notices or other communications required or permitted to be given to the Administrative Agent shall be given to each Lender, and all payments to be made to the Administrative Agent shall be made directly to the Borrower or Lender for whose account such payment is made.

SECTION 8.11 Additional Administrative Agents.

If the Administrative Agent shall from time to time deem it necessary or advisable, for its own protection in the performance of its duties hereunder or in the interest of the Lenders, the Administrative Agent and the Borrower shall execute and deliver a supplemental agreement and all other instruments and agreements necessary or advisable in the opinion of the Administrative Agent to constitute another commercial bank or trust company, or one or more other Persons approved by the Administrative Agent, to act as co-Administrative Agent, with such powers of the Administrative Agent as may be provided in such supplemental agreement, and to vest in such bank, trust company or Person, as such co-Administrative Agent, any properties, rights, powers, privileges and duties of the Administrative Agent under this Agreement or any other Loan Document. The appointment of any co-Administrative Agent at any time pursuant to this Section 8.11 shall be subject to the approval of the Borrower, provided that at such time there shall not have occurred and be continuing any Default or Event of Default, and provided further that the Borrower's consent to any such appointment shall not be unreasonably withheld.

SECTION 8.12 Calculations.

The Administrative Agent shall not be liable for any calculation, apportionment or distribution of payments made by it in good faith, in the absence of its own gross negligence or

-60-

willful misconduct. If such calculation, apportionment or distribution is subsequently determined to have been made in error, the sole recourse of any Lender to whom payment was due but not made (except as provided in the preceding sentence) shall be to recover from the other Lenders any payment in excess of the amount to which they are determined to be entitled or, if the amount due was not paid by the Borrower, to recover such amount from the Borrower.

SECTION 8.13 Syndication Agent.

As Syndication Agent, Wells Fargo Bank, N.A. shall not have any right, power, obligation, liability, responsibility or duty under this Agreement or any other Loan Document other than those applicable to all Lenders as such. Without limiting the foregoing, Wells Fargo Bank, N.A. shall not have any or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on Wells Fargo Bank, N.A. in deciding to enter into this Agreement or in not taking action hereunder or under the Loan Documents.

SECTION 8.14 Sole Bookrunner.

Each Lender acknowledges that it has not relied, and will not rely, on Union Bank of California, N.A. in deciding to enter into this Agreement or in not taking action hereunder or under the Loan Documents.

SECTION 8.15 Co-Documentation Agents.

Without limiting the foregoing, none of Bank One, NA, BNP Paribas or Mellon Bank, N.A. shall have any or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on Bank One, NA, BNP Paribas or Mellon Bank, N.A. in deciding to enter into this Agreement or in not taking action hereunder or under the Loan Documents.

The rights and remedies of the Administrative Agent and the Lenders under this Agreement and any other Loan

-62-

Document are cumulative and not exclusive of any rights or remedies which the Administrative Agent or any Lender would otherwise have hereunder or thereunder, at law, in equity or otherwise.

(a) The Borrower agrees to pay or cause to be paid and to save the Administrative Agent and each of the Lenders harmless against liability for the payment of all reasonable out-of-pocket costs and expenses (including but not limited to reasonable fees and expenses of counsel) incurred by the Administrative Agent or any Lender from time to time arising from or relating to
(i) in the case of the Administrative Agent, the negotiation, syndication, preparation, execution, delivery, administration and performance of this Agreement and the other Loan Documents, (ii) in the case of the Syndication Agent, the syndication of this Agreement and the other Loan Documents, (iii) in the case of the Administrative Agent, any amendments, modifications, supplements, waivers or consents to this Agreement or any other Loan Document (whether or not ultimately entered into or granted), and (iv) in the case of the Administrative Agent or any Lender, the enforcement or preservation of rights under this Agreement or any other Loan Document (including but not limited to any such costs or expenses arising from or relating to (A) collection or enforcement of an outstanding Loan or any other amount owing hereunder or thereunder by the Administrative Agent or such Lender, and (B) any

-63-

litigation, proceeding, dispute, work-out, restructuring or rescheduling related in any way to this Agreement or the Loan Documents).

(b) The Borrower hereby agrees to pay all stamp, document, transfer, recording, filing, registration, search, sales and excise fees and taxes and all similar impositions now or hereafter determined by the Administrative Agent or any Lender to be payable in connection with this Agreement or any other Loan Documents or any other documents, instruments or transactions pursuant to or in connection herewith or therewith (which determination shall be conclusive provided it is reached in good faith), and the Borrower agrees to save the Administrative Agent and each Lender harmless from and against any and all present or future claims, liabilities or losses with respect to or resulting from any omission to pay or delay in paying any such fees, taxes or impositions.

(c) The Borrower hereby agrees to reimburse and indemnify each of the Indemnified Parties from and against any and all losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel for such Indemnified Party in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not such Indemnified Party shall be designated a party thereto) that may at any time be imposed on, asserted against or incurred by such Indemnified Party as a result of, or arising out of, or in any way related to or by reason of, this Agreement or any other Loan Document, any transaction from time to time contemplated hereby or thereby, or any transaction financed in whole or in part or directly or indirectly with the proceeds of any Loan (and without in any way limiting the generality of the foregoing, including any violation or breach of any Environmental Law or any other Law by the Borrower or any Subsidiary of the Borrower; any Environmental Claim arising out of the management, use, control, ownership or operation of Property by any of such Persons, including all onsite and offsite activities involving Hazardous Materials; or any exercise by the Administrative Agent or any Lender of any of its rights or remedies under this Agreement or any other Loan Document); but excluding any such losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements resulting solely from the gross negligence or willful misconduct of such Indemnified Party, as finally determined by a court of competent jurisdiction. If and to the extent that the foregoing obligations of the Borrower under this subsection (c), or any other indemnification obligation of the Borrower hereunder or under any other Loan Document, are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under applicable Law.

SECTION 9.05 Severability.

The provisions of this Agreement are intended to be severable. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without in any manner affecting the validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction.

-64-

SECTION 9.06 Prior Understandings.

This Agreement and the other Loan Documents, as such agreements shall be amended from time to time, supersede all prior and contemporaneous understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein and therein.

SECTION 9.07 Duration; Survival.

All representations and warranties of the Borrower contained herein or in any other Loan Document or made in connection herewith or therewith shall survive the making, and shall not be waived by the execution and delivery, of this Agreement or any other Loan Document, any investigation by or knowledge of the Administrative Agent or any Lender, the making of any Loan, or any other event or condition whatever. All covenants and agreements of the Borrower contained herein or in any other Loan Document shall continue in full force and effect from and after the date hereof so long as the Borrower may borrow hereunder and until payment in full of all Obligations. Without limitation, all obligations of the Borrower hereunder or under any other Loan Document to make payments to or indemnify the Administrative Agent or any Lender shall survive the payment in full of all other Obligations, termination of the Borrower's right to borrow hereunder, and all other events and conditions whatever. In addition, all obligations of each Lender to make payments to or indemnify the Administrative Agent shall survive the payment in full by the Borrower of all Obligations, termination of the Borrower's right to borrow hereunder, and all other events or conditions whatever.

SECTION 9.08 Counterparts.

This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument.

SECTION 9.09 Limitation on Payments.

The parties hereto intend to conform to all applicable Laws in effect from time to time limiting the maximum rate of interest that may be charged or collected. Accordingly, notwithstanding any other provision hereof or of any other Loan Document, the Borrower shall not be required to make any payment to or for the account of any Lender, and each Lender shall refund any payment made by the Borrower, to the extent that such requirement or such failure to refund would violate or conflict with nonwaivable provisions of applicable Laws limiting the maximum amount of interest which may be charged or collected by such Lender.

SECTION 9.10 Set-Off.

The Borrower hereby agrees that, to the fullest extent permitted by Law, if any Obligation of the Borrower shall be due and payable (by acceleration or otherwise), each Lender shall have the right, without notice to the Borrower, to set-off against and to appropriate and apply to such Obligation any indebtedness, liability or obligation of any nature owing to the Borrower by such Lender, including but not limited to all deposits (whether time or demand, general or special, provisionally credited or finally credited, whether or not evidenced by a

-65-

certificate of deposit) now or hereafter maintained by the Borrower with such Lender. Such right shall be absolute and unconditional in all circumstances and, without limitation, shall exist whether or not such Lender or any other Person shall have given notice or made a demand to the Borrower or any other Person, whether such indebtedness, obligation or liability owed to the Borrower is contingent, absolute, matured or unmatured (it being agreed that such Lender may deem such indebtedness, obligation or liability to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty or any other security, right or remedy available to any Lender or any other Person. The Borrower hereby agrees that, to the fullest extent permitted by Law, any Participant and any branch, subsidiary or affiliate of any Lender or any Participant shall have the same rights of set-off as a Lender as provided in this Section (regardless of whether such Participant, branch, subsidiary or affiliate would otherwise be deemed in privity with or a direct creditor of the Borrower). The rights provided by this
Section are in addition to all other rights of set-off and banker's lien and all other rights and remedies which any Lender (or any such Participant, branch, subsidiary or affiliate) may otherwise have under this Agreement, any other Loan Document, at law or in equity, or otherwise, and nothing in this Agreement or any other Loan Document shall be deemed a waiver or prohibition of or restriction on the rights of set-off or bankers' lien of any such Person.

SECTION 9.11 Sharing of Collections.

The Lenders hereby agree among themselves that if any Lender shall receive (by voluntary payment, realization upon security, set-off or from any other source) any amount on account of the Loans, interest thereon, or any other Obligation contemplated by this Agreement or the other Loan Documents to be made by the Borrower pro rata to all Lenders (or pro rata to holders of Notes) in greater proportion than any such amount received by any other applicable Lender, then the Lender receiving such proportionately greater payment shall notify each other Lender and the Administrative Agent of such receipt, and equitable adjustment will be made in the manner stated in this
Section 9.11 so that, in effect, all such excess amounts will be shared ratably among all of the applicable Lenders. The Lender receiving such excess amount shall purchase (which it shall be deemed to have done simultaneously upon the receipt of such excess amount) for cash from the other applicable Lenders a participation in the applicable Obligations owed to such other Lenders in such amount as shall result in a ratable sharing by all applicable Lenders of such excess amount (and to such extent the receiving Lender shall be a Participant). If all or any portion of such excess amount is thereafter recovered from the Lender making such purchase, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by Law to be paid by the Lender making such purchase. The Borrower hereby consents to and confirms the foregoing arrangements. Each Participant shall be bound by this Section as fully as if it were a Lender hereunder.

SECTION 9.12 Successors and Assigns; Participations; Assignments.

(a) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, all future holders of the Notes, the Agents and their respective successors and assigns, except that the Borrower may not assign or transfer any of its

-66-

rights hereunder or interests herein without the prior written consent of all the Lenders and the Administrative Agent, and any purported assignment without such consent shall be void.

(b) Participations. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time sell participations to one or more commercial banks or other Persons (each a "Participant") in all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of its Commitment and the Loans owing to it and any Note held by it); provided, that

(i) any such Lender's obligations under this Agreement and the other Loan Documents shall remain unchanged,

(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,

(iii) the parties hereto shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and each of the other Loan Documents,

(iv) such Participant shall be bound by the provisions of
Section 9.11, and

(v) no Participant (unless such Participant is an Affiliate of such Lender, or is itself a Lender) shall be entitled to require such Lender to take or refrain from taking action under this Agreement or under any other Loan Document, except that such Lender may agree with such Participant that such Lender will not, without such Participant's consent, take any action, or consent to the taking of any action, of the type described in Section 9.01(a),
(b) or (c).

The Borrower agrees that any such Participant shall be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.04 with respect to its participation in the Commitments and the Loans outstanding from time to time; provided, that no such Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred to such Participant had no such transfer occurred.

(c) Assignments. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable Law, at any time assign all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or any portion of its Commitment and Loans owing to it and any Note held by it) to any Lender, any Affiliate of a Lender or to one or more additional commercial banks or other Persons (each a "Purchasing Lender"); provided, that

(i) any such assignment to a Purchasing Lender which is not a Lender or an affiliate of a Lender shall be made only with the consent (which in each case shall not be unreasonably withheld) of the Borrower (so long as no Default or Event of Default shall have occurred and be continuing) and the Administrative Agent;

-67-

(ii) if a Lender makes such an assignment of less than all of its then remaining rights and obligations under this Agreement and the other Loan Documents, such transferor Lender shall retain, after such assignment, a minimum principal amount of $10,000,000 of the Commitments and Loans then outstanding, and such assignment, unless made to an assignee who is a Lender hereunder prior to such assignment, shall be in a minimum principal amount of $10,000,000 of the Commitments and Loans then outstanding;

(iii) each such assignment shall be of a constant, and not a varying, percentage of the Commitment of the transferor Lender and of all of the transferor Lender's rights and obligations under this Agreement and the other Loan Documents; and

(iv) each such assignment shall be made pursuant to an Assignment and Acceptance.

In order to effect any such assignment, the transferor Lender and the Purchasing Lender shall execute and deliver to the Administrative Agent a duly completed Assignment and Acceptance (including the consents required by clause (i) of the preceding sentence) with respect to such assignment, together with any Note or Notes subject to such assignment and a processing and recording fee of $3,500; and, upon receipt thereof, the Administrative Agent shall accept such Assignment and Acceptance. Upon receipt of notice from the transferor Lender that it has received the consideration described in the Assignment and Acceptance, the Administrative Agent shall record such acceptance in the Register. Upon such execution, delivery, acceptance and recording, from and after the close of business at the Administrative Agent's Principal Office on the settlement date specified in such Assignment and Acceptance:

(x) the Purchasing Lender shall be a party hereto and, to the extent provided in such Assignment and Acceptance, shall have the rights and obligations of a Lender hereunder, and

(y) the transferor Lender thereunder shall be released from its obligations under this Agreement to the extent so transferred (and, in the case of an Assignment and Acceptance covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party to this Agreement) from and after the settlement date.

On or prior to the settlement date specified in an Assignment and Acceptance, the Borrower, at its expense, shall execute and deliver to the Administrative Agent (for delivery to the Purchasing Lender) new Notes evidencing such Purchasing Lender's assigned Commitment or Loans and (for delivery to the transferor Lender) replacement Notes in the principal amount of the Loans or Commitment retained by the transferor Lender (such Notes to be in exchange for, but not in payment of, those Notes then held by such transferor Lender). Each such Note shall be dated the date and be substantially in the form of the predecessor Note. The Administrative Agent shall mark the predecessor Notes "exchanged" and deliver them to the Borrower. Accrued interest and accrued fees shall be paid to the Purchasing Lender at the same time or times provided in the predecessor Notes and this Agreement.

-68-

(d) Register. The Administrative Agent shall maintain at its office a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive absent manifest error and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of the Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Financial and Other Information. The Borrower authorizes the Administrative Agent and each Lender to disclose to any Participant or Purchasing Lender (each, a "transferee") and any prospective transferee any and all financial and other information in such Person's possession concerning the Borrower and its Subsidiaries and Affiliates which has been or may be delivered to such Person by or on behalf of the Borrower in connection with this Agreement or any other Loan Document or such Person's credit evaluation of the Borrower and its Subsidiaries and Affiliates.

(f) Assignments to Federal Reserve Bank. Any Lender may at any time assign all or any portion of its rights under this Agreement, including without limitation any Loans owing to it, and any Note held by it, to a Federal Reserve Bank. No such assignment shall relieve the transferor Lender from its obligations hereunder.

(g) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC") the option to fund all or any part

of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to the terms hereof. The funding of a Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the Granting Lender to the same extent, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. Notwithstanding anything to the contrary contained in this Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. 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 9.13 Governing Law; Submission to Jurisdiction Waiver of Jury Trial; Limitation of Liability.

(a) Governing Law. THIS AGREEMENT AND ALL OTHER LOAN DOCUMENTS (EXCEPT TO THE EXTENT, IF ANY, OTHERWISE EXPRESSLY STATED IN SUCH OTHER LOAN DOCUMENTS) SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

This AMENDATORY AGREEMENT, executed April 11, 1995, is entered into by the UNITED STATES OF AMERICA (Government), Department of Energy, acting by and through the Bonneville Power Administration (Bonneville), and SIERRA PACIFIC POWER COMPANY (Company), a corporation of the State of Nevada. Bonneville and Company are sometimes referred to collectively as "Parties."

WITNESSETH:

WHEREAS the Parties entered into a General Transfer Agreement (GTA), Contract No. DE-MS79-88BP92436, dated February 25, 1988, which provides, among other matters, for the transfer of electric power and energy to Wells Rural Electric Company (Wells). The Company is currently providing up to 45 MW of transfer service under the GTA. Bonneville delivers this electric power and energy at the Midpoint Point of Replacement; and

WHEREAS Bonneville has requested the Company provide additional firm transfer service to Bonneville's Wells load and the Company has expressed a desire to provide such additional transfer service. However, any additional transmission service which is provided by the Company is subject to the same terms and conditions as the existing 45MW of transfer service under the GTA until the time that system improvement s are completed that result in an increase of 200 MW or more to the Company's net import capability (System Improvements); and

WHEREAS the Company is undertaking local system additions and improvements required to serve the Carlin Area Customer loads, hereinafter referred to as the Carlin Area Upgrades, and Wells worked with the Company to choose the best plan of service at the lowest possible cost; and

WHEREAS Bonneville and the Company have agreed to undertake and participate in joint engineering studies to develop a long-range plan of service designed to address and resolve service limitations facing the Company's system; and

WHEREAS the Company and Idaho Power Company (Idaho) jointly own the North Valmy Electric Generation Station (Valmy), located near Battle Mountain, Nevada; and


WHEREAS Bonneville intends to provide, or arrange to provide, scheduled delivery of Valmy Generation to Carlin and Maggie Creek Subsidiaries; and

WHEREAS Bonneville and the Company have agreed that the northbound/Valmy schedules may be interrupted if the 345 kV line between Midpoint and Humboldt (Line No. 3419) is unavailable;

NOW, THEREFORE, in consideration of the promise and covenants contained herein, the Parties agree to amend the GTA as follows:

1. AMENDMENT TERM

This Amendment shall be effective after Rural Electrification Administration approval of Revision No. 1 to Exhibit L of the Power Sales Contract (Contract No. DEMS79-81BP90571) between Bonneville and Wells and upon Federal Energy Regulatory Commission (FERC) acceptance of this Amendment in its entirety and without change ("Amendment Effective Date") and shall continue in effect concurrent with the term specified in section 1 of the GTA. If FERC does not accept this Amendment in its entirety and without change, the Parties shall determine whether both Parties are willing and able to modify this Amendment to comply with such FERC order. If the Parties are unable to reach an acceptable modification within a 30-day period, the Parties shall exercise best efforts to negotiate alternative arrangements to meet the same goals.

2. EXHIBITS

Section 3 of the GTA is amended to read as follows:

"Exhibits A through J and any revisions thereto are made a part of this Agreement. The Company shall be the Transferor and Bonneville's Customer shall be the Transferee mentioned in Exhibit A."

3. PROVISIONS RELATING TO DELIVERY

Section 4(a) of the GTA is amended to read as follows:

-2-

"(a) Electric power and energy shall be made available by the Company at all times during the term hereof at the points of delivery described in Exhibit B (Points of Delivery), in the amount of Bonneville's Customer's requirements at such points and the approximate voltages specified therein; provided however, that Bonneville shall make available, pursuant to section 5, electric power and energy at the Points of Replacement specified in Exhibit B; provided, further, that the Transfer Trip load as defined in section 4(f), may be interrupted:

(1) in the event of an outage on the Midpoint-Humboldt-Coyote Creek 345 kV transmission lines which reduces the Company's import capability, or

(2) in the event of an outage on the Company's 120 kV transmission system serving the Carlin area and the Company is unable to serve both the Company's customer loads and Bonneville's Customer loads, in which case interruption of the loads will be shared equitably between the Parties, or

(3) in the event of Loss of Line No. 3419 and the Company is unable to provide service to Bonneville's loads from inside the Company's import boundary.

In no event shall the Company be obligated to import electric power and energy hereunder at a demand level in excess of the import demand limit specified in Exhibit B, except where otherwise agreed. If any of Bonneville's Customer's load is interrupted, the Company may provide service pursuant to section 6 of the GTA.

In the event insufficient import capability to the Company's system exists, Bonneville shall provide power in excess of the demand limit from inside the Company's import boundary in a manner specified by the Company, or reduce deliveries accordingly. The Company will give priority to residential customers and other critical loads in its use of Valmy Generation."

-3-

4. PLANNING INFORMATION

Section 4(c) of the GTA is amended to read as follows:

"(c) Bonneville shall submit, within 45 days following acceptance by FERC for filing (Filing Date), a one-time 10-year forecast listing peak demands, by Point of Delivery, for each calendar month of the 10-year period. This forecast shall be incorporated in Exhibit G. Then, beginning in year 6 of this Amendment and continuing for the term of this Agreement, Bonneville shall submit, by July 1 of each year, a 5-year forecast of peak demands by Points of Delivery, for each calendar month of the 5-year period. Exhibit G attached hereto shall be modified each July 1 to incorporate the fifth year of such 5-year forecast. Such information shall be relied upon by the Company for system and marketing planning.

In the event Bonneville desires to increase forecast demands for a month or months for which a forecast peak demand has been previously established, the Company shall, at its sole discretion, determine whether such incremental capacity can be made available to Bonneville. In the event the Company is unable to serve the incremental demand requested by Bonneville, it shall provide notice of its inability to do so within 60 days of Bonneville's increased Exhibit G forecast submittal. The Company may, but shall not be obligated under this Agreement to, provide import capacity in excess of the amounts established pursuant to Exhibit G of this Agreement.

In the event Bonneville desires to reduce the forecast demands of this Agreement, the Company shall made a reasonable effort to market the resulting excess capacity reserved for Bonneville; however, if this excess capacity becomes unused, Bonneville will be subject to a Charge for Reduction of Service as shown in Exhibits E and G."

I. TERM

Unless sooner terminated or canceled, the term of this Agreement ("Term") shall be five (5) years commencing January 1, 2002 and ending December 31, 2006.

II. SOURCE MINES

A. The Coal supplied hereunder shall be produced from SELLER's Sufco, Skyline and Dugout Canyon ("Dugout") mines located in Emery and Sevier Counties, Utah (collectively the "Mines"). SELLER represents and warrants that it has dedicated the Mines to the performance of this Agreement subject to ARTICLE X. QUALITY SPECIFICATIONS, Section F below. SELLER shall have the right to direct which of the Mines will originate shipments in accordance with ARTICLE IV. ORDERING. SELLER shall use reasonable efforts to maximize shipments from Sufco, and in no event, shall shipments from Sufco be less than 350,000 tons during the period July 1, 2003 through December 31, 2003 and 700,000 tons per year in 2004 through 2006. Additionally, shipments from Dugout shall be no more than 500,000 tons in any calendar year during the Term of this Agreement. Currently, no shipments are anticipated to come from Sufco during calendar year 2002.

B. SELLER represents and warrants that the Mines contain a sufficient quantity of economically recoverable coal that meets the quality specifications and quantity requirements of this Agreement. SELLER further warrants that the title to all Coal delivered under this Agreement shall be good and that such Coal shall be delivered free from any claim, lien or other encumbrance. SELLER shall indemnify BUYER against any and all expenses, damages, and liabilities resulting from breach of this warranty.

C. Subject to the prior written approval of BUYER, SELLER shall have the right to supply coal from sources other than the Mines ("Substitute Coal"), subject to all other terms and conditions of this


Agreement, provided that any Substitute Coal shall not result in a higher delivered price to BUYER calculated in dollars per million Btu F.O.B. the Station than the price in effect for Skyline under this Agreement at the time of shipment of the Substitute Coal, and provided further that Substitute Coal shipments shall not reduce coal deliveries from Sufco below the levels set forth in ARTICLE II. SOURCE MINES, Section A.

D. BUYER shall have the right to divert shipments to the following generating stations:

Pinon Pine, Sparks, Nevada
Reid Gardner, Moapa, Nevada
Jim Bridger, Point of Rocks, Wyoming
Boardman, Castle, Oregon

III. QUANTITY

A. The quantity of Coal to be delivered and purchased hereunder on an annual basis shall be the base tonnage specified in the table below ("Base Tons"). At the BUYER'S sole option, the annual Base Tons may be decreased by the amount specified in the table below ("Reduced Tonnage Option"). The BUYER'S Reduced Tonnage Option shall only be valid with respect to the specified calendar year and the annual Reduced Tonnage Option volumes shall not carry over to the next calendar year.

                                   Base Tons     Reduced Tonnage
                                   ---------     ---------------
January 1 - December 31, 2002      1,030,000            0
January 1 - December 31, 2003      1,200,000            0
January 1 - December 31, 2004      1,600,000         75,000
January 1 - December 31, 2005      1,600,000         75,000
January 1 - December 31, 2006      1,600,000         75,000

B. As BUYER intends to take delivery in unit trains, actual tonnage delivered during any calendar year may differ slightly from the Base Tons (less any Reduced Tonnage) in order to accommodate deliveries in unit train lots. Provided, however, that the amount of over-shipment or under-shipment in any calendar year shall be no more than 10,000 Tons of Coal. Differences resulting from truing up of actual deliveries (but not including variances in deliveries due to an event of force majeure) with Base Tons (less any Reduced Tonnage) during any calendar year will be carried over into the following contract year such that the Base Tons for the following year would be decreased or increased by an amount which takes these differences into account. Additionally, BUYER and SELLER agree that up to 50,000 tons of coal per year may be carried into the next calendar year, and shall be delivered by SELLER to BUYER during the first calendar quarter of such calendar year under a mutually agreeable shipment schedule and at the price in effect for the calendar year in which the Coal was originally scheduled for delivery. BUYER and SELLER agree that the Term of this Agreement may be extended for up to three months to allow for the delivery of such Coal.

C. BUYER shall have the right to resell the Base Tons in any calendar year to a third party, provided however, that SELLER shall have the right, but not the obligation to purchase said amount of Coal from BUYER at the price BUYER could otherwise resell the Coal to the third party. In such cases, BUYER will notify SELLER of its intent to resell any coal sold hereunder, specifying the price, volume, and term, and unless otherwise agreed, SELLER shall then have three business days to exercise its right to repurchase said Coal. BUYER agrees to identify the amount of Coal intended for resale as part of the shipment scheduling requirements set forth in ARTICLE IV. ORDERING, Section B. Additionally, all terms and conditions contained in this Agreement between BUYER and SELLER shall apply to all Coal resold in accordance with this ARTICLE III. QUANTITY, Section C.

IV. ORDERING

A. Shipments utilizing one unit train set will be scheduled on an approximate ratable basis. Further, the parties recognize that BUYER will schedule a second unit train set from time to time and that the operation of the second train set will cause total monthly shipments to be substantially in excess of the approximate ratable basis utilizing one trainset.

B. BUYER shall notify SELLER on or before the fifteenth day of each month of the quantity of Coal to be shipped during the following month. (ie, BUYER will notify SELLER on or before January 15th of the amount of Coal to be shipped during February.) In addition, BUYER shall provide SELLER with its best estimate of the quantity of Coal to be shipped during the following eleven months. Within five days of receipt of BUYER's notice, SELLER shall respond in writing, or by facsimile or electronic mail, to BUYER confirming BUYER's schedule and specifying the source of each of the following month's shipments among Sufco, Skyline and Dugout. In addition, SELLER's response shall also include its best estimate of the sources of the projected quantities of Coal for the following eleven months.

In the event SELLER is required to estimate future Coal deliveries beyond the twelve-month period, then the following percentage amounts shall be used as an estimate of Coal deliveries from SELLER'S Mines, and shall become effective in the first month following the twelve month forecast period described hereunder:

             Sufco     Skyline    Dugout
             -----     -------    ------

C. SELLER shall be liable for any incremental transportation charges assessed to BUYER as a result of SELLER's failure to load cars to a minimum car weight of 113 net tons for railcars in a trainload consisting of aluminum 286,000 gross net weight in pounds railcars, and 98 net tons for railcars in a trainload consisting of steel/aluminum 263,000 gross net weight in pounds railcars. BUYER shall have the right to specify new and revised minimum railcar weights from time to time.

D. Rail transportation shall be ordered by BUYER and shall be paid for by "BUYER except when shipments are rejected or acceptance of shipments is revoked by BUYER, which, in such event rail transportation costs will be borne by SELLER. SELLER shall make reasonable efforts to make the necessary arrangements with the railroad for the placement of railcars at the Loading Facility in accordance with the rail transportation arrangements made by BUYER.

E. Upon arrival of each train at SELLER's Loading Facility and prior to commencing loading, SELLER shall make reasonable efforts to check each car for the presence of foreign material and check that each car door is closed and locked.

F. Upon the loading of each train for shipment, SELLER shall promptly fax a shipping notice to: North Valmy Generation Station; Attention: North Valmy Plant Administration; (FAX #: 775-834-3164). The shipping notice shall include the shipment date, shipment number, car initials and numbers, tonnages and the trainload identification numbers.

VII. TITLE AND RISK OF LOSS

Title and risk of loss of the Coal shall pass from SELLER to BUYER as the Coal is progressively loaded into railcars to be provided by BUYER.

VIII. WEIGHING

A. For billing and all other purposes under this Agreement, the weight of the Coal delivered hereunder shall be determined by certified weighing systems at the Loading Facilities when the Coal is loaded. At its expense, SELLER shall directly (or, in the case of Savage Coal Terminal cause the Loading Facility Operator to) inspect, test and calibrate the weighing and measuring devices at least semiannually in accordance with accepted methods. SELLER shall provide copies of the scale certification reports to BUYER. SELLER shall notify BUYER at least seven days prior to such testing and BUYER shall have the right to have a representative present to observe such weighing inspections or tests.

B. If SELLER's scales are determined to be in error in excess of two-tenths of one percent (.2%) as determined by such inspection and certification, an appropriate adjustment shall be made to the Coal's weight and related invoices and payments. Such adjustment shall be retroactive to the time of the error if such time can be factually ascertained. If the time of error cannot be ascertained, it will be deemed to be one-half the time between the last certification of such scales and the time the error in weighing was corrected.

IX. SAMPLING AND ANALYSIS

A. SELLER warrants that Coal samples will be taken in accordance with ASTM standards at the Loading Facilities.

B. For the purposes of determining conformance of each shipment of Coal to ARTICLE X. QUALITY SPECIFICATIONS, or any other provision of this Agreement, a representative sample of the Coal shall be collected, as set forth in Section C of this ARTICLE IX. SAMPLING AND ANALYSIS, below, in accordance with ASTM standard methods at the Loading Facility as Coal is loaded into

4

each unit train. BUYER may, at its own risk and expense, have a representative present to observe such sampling. The presence of BUYER's representative at the time SELLER samples the Coal does not relieve the SELLER of its obligations to sample and analyze the Coal in conformance with the terms and conditions of this ARTICLE IX. SAMPLING AND ANALYSIS.

C. SELLER shall cause a representative sample to be taken in accordance with ASTM standards at the Loading Facility as Coal is loaded into each unit train. The sample shall be taken by an ASTM mechanical sampler. SELLER shall divide each sample into three parts in accordance with ASTM standards and shall place the parts in suitable airtight containers each of which shall be sealed, documented and controlled for security purposes.

1. (a) SELLER shall analyze the first part ("Original Sample") on a preliminary basis for Total Moisture, Ash, BTU/lb., and Sulfur
(Sulfur to be stated in pounds of sulfur dioxide per million Btu) ("Preliminary Analysis") in accordance with ASTM standards. If the Preliminary Analysis shows that the Coal fails to meet any one of the Rejection Coal Specifications as set forth in ARTICLE X. QUALITY SPECIFICATIONS, BUYER may, at its option, exercise any of its rights set forth in ARTICLE XI. COAL QUALITY PENALTY/REFUSABLE COAL. SELLER shall fax a copy the Preliminary Analysis to BUYER within twelve (12) hours of collecting the Original Sample. BUYER shall designate an agent to receive such results after normal business hours.

(b) In addition, SELLER shall analyze the Original Sample for Total Moisture, Ash, BTU/lb., Ash Fusion Temperature (H=W) and Sulfur
(Sulfur to be stated in pounds of sulfur dioxide per million Btu) in accordance with ASTM Methods ("Final Analysis"). SELLER shall fax a copy of the Final Analysis to BUYER within 72 hours after collecting the Original Sample.

(c) BUYER may, at its sole option and expense, require that the Final Analysis include further testing in accordance with ASTM standards for any or all of those characteristics in ARTICLE X. QUALITY SPECIFICATIONS which were not described in ARTICLE IX. SAMPLING AND ANALYSIS, Section C.1(b). If this analysis shows that the Coal fails to meet any one of the suspension limits set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A, BUYER may, at its option, exercise any of its rights set forth in ARTICLE
XII. NONCONFORMING COAL.

2. (a) The second part of the representative sample ("Duplicate Sample") shall be held by SELLER for at least thirty (30) days. BUYER, at its sole expense, may have the Duplicate Sample analyzed in accordance with ASTM standards for any or all of the characteristics in ARTICLE X. QUALITY SPECIFICATIONS ("BUYER's Analysis"). Except as provided in ARTICLE IX. SAMPLING AND ANALYSIS, Section 2(c) , a copy of BUYER's Analysis shall be made available to SELLER within ten (10) days of receipt of the results of BUYER's Analysis.

(b) If the results of BUYER'S Analysis are within the ASTM allowable reproducibility limits from the result of SELLER's Final Analysis, then SELLER's Final Analysis shall control for purposes of determining compliance with ARTICLE X. QUALITY SPECIFICATIONS, or any other term of this Agreement.

5

(c) If SELLER's Final Analysis and BUYER's Analysis results vary by more than the ASTM allowable reproducibility limits, then:

(i) A copy of BUYER's Analysis shall immediately be made available to SELLER; and

(ii) SELLER shall cause the Referee Sample (referred to in Sub-section (3) of this ARTICLE, below) to immediately be analyzed as provided in Sub-section (3), below, and the results shall immediately be made available to both SELLER and BUYER.

3. (a) The third part of the representative sample ("Referee Sample") shall be held by SELLER for at least forty-five (45) days for analysis by an independent laboratory as set forth below.

(b) If SELLER's Final Analysis and BUYER's Analysis results vary by more than the ASTM allowable reproducibility limits, then the Referee Sample shall be analyzed in accordance with ASTM standards by a mutually acceptable independent laboratory. The results of the Referee Sample analysis shall be furnished to both SELLER and BUYER and shall control for purposes of determining compliance with ARTICLE X. QUALITY SPECIFICATIONS and any other term of this Agreement. The cost of the Referee Sample analysis shall be paid equally by BUYER and SELLER.

D. SELLER shall, at its own cost, cause the mechanical sampler to be dynamically bias tested by an independent third party at least every 24 months during the Term of this Agreement. SELLER shall provide copies of the sampler test reports to BUYER. BUYER shall have the right to have a representative present during the sampler tests.

B. SELLER agrees to permit and/or make all necessary arrangements for access during normal business hours by BUYER, at BUYER's risk and expense to any properties, equipment or facilities related to SELLER'S performance under this Agreement.

C. The Coal shall be mixed thoroughly so that the quality thereof after being loaded into the rail cars shall be consistent within each car of the unit train and that the Coal shall be prepared substantially free of impurities.

D. BUYER, through its agents, representatives or employees, shall have the right to inspect the Coal at BUYER's risk and expense at any time prior to unloading at the Station and to inspect any properties, equipment or facilities during normal business hours related to SELLER's performance under this Agreement, including, but not limited to, SELLER's reserves, mining operations, hauling operations, storage operations or loading operations. BUYER's inspection pursuant to this ARTICLE X. QUALITY SPECIFICATIONS, Section D, does not relieve SELLER of its obligations to deliver Coal to BUYER in conformance with the quality specifications set forth in this ARTICLE X. QUALITY SPECIFICATIONS.

E. BUYER shall be entitled to randomly sample the Coal using ASTM standards during any such inspection ("Inspection Sample") and analyze the Inspection Sample using ASTM standard methods.

7

F. Because BUYER has not utilized Coal from Dugout at the Station, BUYER requires that a test burn be conducted. The test burn will require up to 50,000 tons of representative quality Coal from Dugout and would be conducted on a schedule mutually agreeable between BUYER and SELLER. If, as a result of the test bum, BUYER, in its sole reasonable judgment, determines that Coal from Dugout is not suitable for use at the Station, BUYER shall so notify SELLER in writing no later than thirty (30) days after completion of the test burn. SELLER agrees to terminate shipments from Dugout upon receipt of SELLER's notice. BUYER and SELLER agree to meet thereafter to discuss the reasons for the unsuitability and what, if anything, can be done to make Coal from Dugout suitable. BUYER and SELLER agree that SELLER intends to utilize Coal from Dugout to supply a portion of the annual volumes set forth in ARTICLE III. QUANTITY, Section A. If BUYER determines the Coal from Dugout is unsuitable, SELLER may elect to reduce the annual volumes set forth in ARTICLE III. QUANTITY, Section A, by 15% for the remainder of 2002-2003 and by 10% for 2004-2006. SELLER shall notify BUYER in writing of its election to reduce volumes no later than seven days after receipt of BUYER's notice of Dugout's unsuitability for use at the Station.

G. BUYER AGREES THAT SELLER MAKES NO EXPRESS WARRANTIES OTHER THAN THOSE SET FORTH IN THIS AGREEMENT. SELLER MAKES NO WARRANTY CONCERNING THE SUITABILITY OF COAL DELIVERED HEREUNDER FOR USE IN BUYER'S PLANT, OR OTHER ELECTRIC GENERATION STATIONS. ALL WARRANTIES OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE OR ARISING FROM A COURSE OF DEALING OR USAGE OF TRADE ARE SPECIFICALLY EXCLUDED.

H. If, at any time after the date deliveries commence under this Agreement, BUYER reasonably and in good faith determines a material inability to burn the Coal purchased under this Agreement, BUYER may, at its option and upon notice confirmed in writing and sent to SELLER by certified mail, facsimile, or other electronic methods, suspend future shipments except shipments already loaded into railcars from the Mine(s) which produce the unacceptable Coal. SELLER may, within thirty (30) days of receipt of BUYER's notice, provide BUYER with reasonable assurances that subsequent monthly deliveries of Coal shall improve the combustion characteristics of the Coal. If SELLER fails to provide such assurances within said thirty day period, or if SELLER provides assurance but is unable to cure BUYER's inability to burn the Coal, BUYER may terminate shipments from the affected Mine(s) by giving written notice of such termination within five (5) days from the end of such thirty day period. In the event BUYER exercises its right under this Section, and terminates deliveries from the affected Mine(s), then SELLER shall continue to supply Coal from the unaffected Mine(s) and the shortfall created by the unburnable Coal would be determined in accordance with the forecast schedule set forth in ARTICLE
IV. ORDERING, Section B. Additionally, both parties shall be relieved from any further rights, duties, obligations or liabilities under this Agreement for that portion of deliveries that would have been delivered from the affected Mine(s), except for payment of any sums due and owing for deliveries made under this Agreement prior to the termination of deliveries from the affected Mine(s).

I. In the event that certain Coal quality parameters create combustion related problems at the Station, BUYER may, upon notice confirmed in writing and sent to SELLER by certified mail, facsimile, or other electronic method, suspend future shipments except shipments already loaded into railcars. SELLER shall, within thirty (30) days of receipt of BUYER's notice, provide BUYER with reasonable assurances that subsequent monthly deliveries of Coal shall improve the combustion characteristics of the Coal. If SELLER fails to provide such assurances within said thirty (30) day period, or if SELLER provides assurance but is unable to change the certain Coal quality parameters which created such combustion related problems, BUYER may terminate shipments from the affected Mine by giving written notice of such termination within five (5) days from the end of the thirty (30) day period. Additionally, SELLER shall continue to supply Coal from the unaffected Mines and the shortfall created by the non-conforming Coal would be determined in accordance with the forecast

8

schedule set forth in ARTICLE IV. ORDERING, Section B. A waiver of this right for any one period by BUYER shall not constitute a waiver for subsequent periods. If SELLER provides such assurances to BUYER, shipments hereunder shall resume and any tonnage deficiencies resulting from suspension may be made up subject to the mutual agreement of BUYER and SELLER. BUYER shall not unreasonably withhold its acceptance of SELLER'S assurances, or delay the resumption of shipments. The parties recognize that BUYER, in accordance with ARTICLE XI. COAL QUALITY PENALTY/REFUSABLE COAL, has the right to reject shipments that do not conform with the rejection limits set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section
A., for Total Moisture, Ash, Sulfur (Sulfur to be stated in pounds of sulfur dioxide per million Btu), and Btu/lb. This Section I. is intended to apply to all constituents and properties of the Coal shipped hereunder (except for Total Moisture, Ash, Btu/1b., and Sulfur, with Sulfur to be stated in pounds of sulfur dioxide per million Btu) that individually or in combination cause the Coal to be unburnable as defined herein.

XI. COAL QUALITY PENALTY/REFUSABLE COAL

A. If the quality of any trainload of Coal hereunder based upon the Preliminary Analysis authorized under ARTICLE IX. SAMPLING AND ANALYSIS exceeds the rejection limits set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A, by an amount that causes it to be unburnable in the sole discretion of the BUYER, BUYER may refuse to accept delivery of the trainload, all expenses to be paid by SELLER. BUYER may stop any train in route all expenses to be paid by the SELLER. BUYER shall-give SELLER such notice by telephone as soon as is reasonably possible and shall provide written notice no more than two business days after such selection is made by BUYER. BUYER must reject such Coal within twenty-four (24) hours of receipt of the Preliminary Analysis or such right to reject is waived.

When a train is rejected, SELLER shall have twenty-four (24) hours from the time BUYER notifies SELLER of the rejection to make arrangements to dispose of the Coal. BUYER may, at its discretion, lease the train to SELLER at prevailing lease rates in order to transport rejected Coal to a new destination. The train will be returned to BUYER at any of SELLER's Loading Facilities within 6 days of the rejection notice. SELLER agrees not to hold BUYER responsible for missing any loading dates or volumes due to SELLER's use of train for transporting rejected Coal.

B. If the quality of any trainload of Coal hereunder exceeds the reject limits set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A, and BUYER intends to utilize the Coal, that shipment shall be subject to a $1.00 per ton penalty that shall be credited to BUYER. This penalty shall be in addition to the price adjustments set forth in ARTICLE XV. HEAT CONTENT ADJUSTMENT, and ARTICLE XVI. S02 ADJUSTMENTS.

XII. NON-CONFORMING COAL

A. Should the weighted monthly average of all shipments from each Mine based upon the Final Analysis or Referee Sample Analysis of all monthly shipments, fail to meet any one or more of the suspension limits (except BTU/1b) set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A., or should SELLER deliver three (3) trains in a six (6) month period that fail to meet the rejection limits set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A., BUYER may upon notice confirmed in writing and sent to SELLER by certified mail, facsimile, or other electronic method, suspend future shipments with the exception of any shipments already loaded into railcars. SELLER shall, within thirty (30) days of receipt of BUYER's notice, provide BUYER with reasonable assurances that subsequent monthly deliveries of Coal shall meet or exceed the suspension limits (except BTU/1b) set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A. If SELLER fails to provide such assurances within said thirty (30) day period, BUYER may terminate shipments

9

from the affected Mine by giving written notice of such termination at the end of the thirty (30) day period. Additionally, SELLER shall continue to supply Coal from the unaffected Mines and the shortfall created by the non-conforming Coal would be determined in accordance with the forecast schedule set forth in ARTICLE IV. ORDERING, Section B. A waiver of this right for any one period by BUYER shall not constitute a waiver for subsequent periods. If SELLER provides such assurances to BUYER, shipments hereunder shall resume and any tonnage deficiencies resulting from suspension may be made up subject to the mutual agreement of BUYER and SELLER. BUYER shall not unreasonably withhold its acceptance of SELLER'S assurances, or delay the resumption of shipments.

B. All costs,.expenses or damages incurred by BUYER in the course of SELLER assuring BUYER of SELLER's ability to conform to the quality specifications, after giving notice to SELLER of SELLER's failure to meet any one or more of such suspension limits, shall be paid to BUYER by SELLER. Nothing herein shall limit the remedies available to BUYER under the Uniform Commercial Code as enacted in the State of Nevada (UCC).

XIII. DEFAULT EVENTSIREMEDIES

A. A default event shall mean any of the following:

1. SELLER fails to supply Coal subject to:

(a) The quality specifications set forth under the suspension and rejection limits of ARTICLE X. QUALITY SPECIFICATIONS, Section
A., and

(b) The quantity specifications set forth under ARTICLE III. QUANTITY. Sections A. and B., unless otherwise excused under ARTICLE XVIII. FORCE MAJEURE.

2. SELLER fails to provide assurances as required in ARTICLE XII.


NON-CONFORMING COAL, Section A.

3. SELLER, having given adequate assurances, fails to commence delivery of Coal conforming to the Typical Coal Specifications set forth in ARTICLE X. QUALITY SPECIFICATIONS, Section A., within thirty (30) days after the date of SELLER providing assurances to BUYER as required in ARTICLE XII. NON-CONFORMING COAL, Section A.

4. SELLER delivers within three (3) months after the date of SELLER'S resumption of shipments under ARTICLE XII. NON-CONFORMING COAL,
Section A, three shipments of Coal which fail to meet any one or more of the reject limits set forth in ARTICLE X. QUALITY SPECIFICATIONS,
Section A.

5. Either party commits a material breach of its obligations under this Agreement and the breaching party fails to cure such material breach within thirty (30) days after receipt of written notice from the non-breaching party describing the breach.

6. BUYER or SELLER fails to pay any payment required by the Agreement when due and such failure is not remedied within fourteen (14) days after written notice thereof, provided however, that the payment is not subject to ARTICLE XVII. PAYMENT.

7. BUYER or SELLER files a petition or otherwise commences, authorizes, or acquiesces in the commencement of a proceeding or cause of action under any bankruptcy or similar

10

law for the protection of creditors; has such petition filed or a proceeding commenced against it, otherwise becomes bankrupt or insolvent (however evidenced); fails or is unable generally to pay its debts as they become due; or seeks or becomes subject to the appointment of an administrator, provisional liquidator, conservator, receiver, trustee, custodian or other similar official for all or substantially all of its assets.

B. In the event either party is in default, the other party may, in addition to and not in limitation of other rights provided for in this Agreement, do one or more of the following:

1. Cancel this Agreement.

2. Exercise all remedies available to either BUYER or SELLER under the entire UCC or any provision thereof.

XIV. COAL PRICE

A. The price per ton (2000 pounds) to be paid by BUYER to SELLER for the Coal delivered hereunder shall be fixed for each calendar year for the duration of the agreement at the prices indicated below F.O.B. rail cars at SELLER'S Loading Facility for each Mine. This price includes all taxes, costs of compliance with all laws and regulations, royalties and other fees applicable to the production and sale of Coal under this Agreement, except that State of Nevada Use Tax shall be to BUYER's account.

                                      Sufco     Skyline       Dugout
                                     ------     -------       ------
Effective January 1, 2002            $18.50      $19.00       $19.30
Effective January 1, 2003            $19.05      $19.57       $19.88
Effective January 1, 2004            $19.63      $20.15       $20.48
Effective January 1, 2005            $20.22      $20.76       $21.09
Effective January 1, 2006            $20.82      $21.38       $21.72

B. SELLER represents that the cost of compliance with all governmental laws and regulations in effect as of November 15, 2001 is included in the initial Coal prices. Subsequent to such date new laws or regulations, changes in the interpretation or enforcement practices concerning existing laws as well as changes in presently existing federal, state, and local laws, rules and regulations that impose additional costs, or reduce such costs being imposed to mine, process, transport, or sell Coal and which were not being incurred as of November 15, 2001, (collectively "Change in Governmental Imposition") shall be passed through to BUYER or SELLER, as the case may be, pursuant to Sections C through H below. SELLER and BUYER agree that cost changes due to changes in percentage depletion allowance shall not qualify as a Change in Governmental Imposition.

C. There are two categories of Change in Governmental Imposition:

1. Any Change in Governmental Imposition that is directly assessed against SELLER as a dollar per ton, a dollar per million Btu or as a percent of sales price shall be passed in its entirety to BUYER as an adjustment to the base prices, subject to the limitations in Section E below. Examples include, but are not limited to, regulations impacting Btu, carbon, mercury, sodium dioxide, Federal Black Lung, Federal Reclamation Fee, Severance Tax, and Federal Coal Royalty.

2. Any other Change in Governmental Imposition not described by ARTICLE
XIV. COAL PRICE, Section C.(1) shall be calculated as follows:

11

(a) The total Change in Governmental Imposition shall be calculated for each Mine as each such change is incurred.

(b) The total amount calculated pursuant to Subsection (a) above shall be divided by the total number of tons produced by the respective Mine for the applicable time period involved to yield the dollar per ton impact.

(c) Every Change in Governmental Imposition pursuant to this Subsection (2) will first be rounded to the nearest thousandth of a cent and then reduced by $0.10 per ton. If the Change in Governmental Imposition is less than $0.10 per ton then there shall be no change to the Coal prices.

D. The following procedure applies when SELLER claims that there has been a Change in Governmental Imposition that is eligible to impact Coal prices, but the cumulative Coal price increase for the life of this Agreement in the Governmental Imposition category is less than or equal to $2.00 per ton each in either Subsection C.(1) or Subsection C.(2).

1. SELLER shall notify BUYER within sixty days of the effective date of any Change in Governmental Imposition. Such notification shall include SELLER's non-binding indication of whether the Change in Governmental Imposition is significant.

2. As soon as possible after such notification, SELLER shall provide BUYER with written cost per ton calculations and satisfactory evidence of the pertinent Change in Governmental Imposition. Such calculations, together with supporting documentation and workpapers will be sufficient to allow a knowledgeable person to determine the reasonableness and accuracy of SELLER's calculations.

3. BUYER shall have ninety (90) days to review the materials provided by SELLER pursuant to Subsection (2) above and provide SELLER with notice of acceptance or dispute of such Change in Governmental Imposition and resulting Coal price adjustments.

4. If BUYER accepts SELLER's calculation of the Change in Governmental Imposition, the Coal prices will be adjusted retroactively for a period beginning (i) on the effective date of such Change in Governmental Imposition if SELLER's notice of the same was within the sixty day deadline referenced in Subsection (1) above; or (ii) sixty days prior to the date of SELLER's initial notification if SELLER failed to comply with such deadline. BUYER or SELLER as the case may be shall make payment of a Change in Governmental Imposition that is retroactive within 20 days of SELLER's invoice or credit memorandum, and the per ton impact shall be reflected in the revised Coal prices for subsequent deliveries.

5. If BUYER or SELLER disputes such calculations, then BUYER and SELLER shall have up to sixty days from the notice of dispute to resolve the dispute. If the dispute cannot be resolved within the sixty day period, then the dispute shall be arbitrated as set forth in ARTICLE
XXIII. DISPUTE RESOLUTION, as modified by this Subsection. The sole questions for the arbitrator to decide will be the correct amount of Change in Governmental Imposition and the corresponding change in Coal prices. If BUYER or SELLER elect to arbitrate a dispute arising from a Change in Governmental Impositions, then BUYER and SELLER agree to be bound by the arbitrators' ruling and apply it retroactively to the effective date of such Change in Governmental Imposition pursuant to Paragraph 4 of this Section (D) and this Agreement shall not be terminated as a result of the arbitrators' ruling.

12

E. When the Changes in Governmental Impositions described by ARTICLE XIV. COAL PRICE, Section C.(I) reach a cumulative amount exceeding $2.00 per ton, then these additional procedures will apply following the ninety day review period referenced in Section (D)(3).

1. If BUYER accepts the validity of the charge, BUYER and SELLER agree to meet to discuss which, if either party, agrees to absorb the amount of the ARTICLE XIV. Section C.(1) cost that exceeds $2.00 per ton. Such meeting shall take place within 5 days of BUYER's notice of acceptance as provided for in this ARTICLE XIV. COAL PRICE, Section D.(3). If either party agrees to absorb such amount, then this Agreement shall remain in full force and effect. If neither party agrees to absorb such amount, then this Agreement shall terminate 90 days from the meeting date. During the final ninety day period, the Coal prices shall be adjusted to reflect fifty percent (50%) of the subject ARTICLE XIV. COAL PRICE, Section C.(1) charge and shall not be subject to any other adjustments for a Change in Governmental Imposition for as long as this Agreement remains in effect.

2. If BUYER disputes the validity of the charge, such dispute shall be resolved pursuant to ARTICLE XIV. COAL PRICE, Section D(5).

F. When the Change in Governmental Impositions described in ARTICLE XIV. COAL PRICE, SECTION C.(2) reach a cumulative amount exceeding $2.00 per ton, then these additional procedures will apply following the ninety day review period referenced in Section (D)(3).

1. If the BUYER accepts the validity of the charge, BUYER and SELLER agree to meet to discuss which, if either party, agrees to absorb the amount of this ARTICLE XIV. COAL PRICE, Section C.(2) cost that exceeds $2.00 per ton. Such meeting shall take place within 5 days of BUYER's notice of acceptance as provided for in this ARTICLE XIV. COAL PRICE, Section D.(3). If either party agrees to absorb such amount, then this Agreement shall remain in full force and effect. If neither party agrees to absorb such amount, then this Agreement shall terminate ninety (90) ~ days from the meeting date. During the final ninety day period, the Coal prices shall be adjusted to reflect fifty percent (50%) of the subject ARTICLE XIV. COAL PRICE(C)(2) charge and shall not be subject to any other adjustments for a Change in Governmental Imposition for as long as this Agreement remains in effect.

2. If BUYER disputes the validity of the charge, such dispute shall be resolved pursuant to this ARTICLE XIV. COAL PRICE, Section D.(5).

G. In the event that BUYER contends that SELLER has failed to claim and calculate an available Change in Governmental Imposition, the parties agree as follows:

1. BUYER will give SELLER notice within sixty (60) days of the effective date that it believes that a Change in Governmental Imposition has provided a cost saving opportunity that should be passed through retroactively as of the effective date of such Change in Governmental Imposition to BUYER by an adjustment to the Coal prices. If BUYER fails to notify SELLER of a Change in Governmental Imposition within the required sixty day period, then the effective date of the Change in Governmental Imposition would then become sixty days prior to the date of BUYER's initial notification, unless the discovery of a Change in Governmental Imposition occurs during annual audit by BUYER as set forth in ARTICLE XIX. AUDIT/INSPECTION when the effective date of any change in Coal prices shall be the effective date of the Change in Governmental Imposition.

13

2. SELLER will then calculate the available cost changes related to such Change in Governmental Imposition as soon as possible and calculate the related adjustment to the Coal prices. SELLER shall provide BUYER with its calculations and related documentation sufficient to allow a knowledgeable person to determine the reasonableness and accuracy of the possible cost change on a dollar per ton basis.

3. BUYER shall have ninety (90) days after receiving such documentation, to give SELLER notice of acceptance or dispute of such calculations. If BUYER disputes such calculations, then such dispute will be resolved pursuant to this ARTICLE XIV. COAL PRICE, Section D.(5).

H. BUYER and SELLER mutually agree that time is of the essence as it relates to the obligations of the parties under this ARTICLE XIV. COAL PRICE.

XV. HEAT CONTENT ADJUSTMENT

In the event the weighted average heat content of all Coal shipped in any calendar month is less than the guaranteed Btu/lb as specified in this ARTICLE
XV. HEAT CONTENT ADJUSTMENT, then a Heat Content Penalty in an amount determined by the following formula, shall apply. Heat content adjustments shall be calculated separately for each Mine from which Coal was shipped hereunder

Heat Content Penalty = Price Per Ton x Btu I- Btu2 x Tons Shipped Btul

In the event the weighted average heat content of all Coal shipped in any calendar month is greater than the guaranteed Btu/lb as specified in this ARTICLE XV. HEAT CONTENT ADJUSTMENT, then a Heat Content Premium in an amount determined by the following formula shall apply:

Heat Content Premium=Price Per Ton x Btu2- Btu 1 x Tons Shipped

                                        Btu l

Where:

     "Price Per Ton" =          The price set forth in ARTICLE XIV. COAL
                                PRICE for the Mine in dollars per ton;

     "Btu l" =                  The guaranteed heat content in
                                Btu/lb (as received basis) as
                                follows: Sufco - 11,400, Skyline -
                                11,710, Dugout -- 11,960;

     "Btu2" =                   The weighted average as received
                                heat content (as determined in
                                accordance with ARTICLE IX. SAMPLING
                                AND ANALYSIS) for all Coal shipped
                                for the month from the Mine;

     "Tons Shipped" =           The total number of tons of Coal received
                                for the contract month.

There shall be no Heat Content Premium or Penalty for the month if the weighted average Btu content of all Coal shipped from the Mine in that month is greater than or equal to [Btu1 - 50 Btu/lb.], but less than or equal to [Btu1 + 50 Btu/1b.].

BUYER shall send SELLER a written calculation of the Heat Content Penalty or Premium by Mine within thirty (30) days after the end of each month. Payment or credit shall be made within fifteen (15) days of receipt of the written calculation.

14

XVI. S02 ADJUSTMENTS

If the weighted average pounds of S02 per million BTU (lbs S02/MMBTU) on an as received basis of all shipments accepted by BUYER in a calendar month from a Mine differs from the base lbs S02/MMBTU for that Mine, then a S02 adjustment in an amount determined by the following formula shall apply

Sulfur Adjustment = (Base S02 - Actual S02) X (BTU2) X (Value S02)

                                       1,000,000

Where:

     "Base S02" =   The specification in lbs S02/MMBTU (as received basis)
                    for the Mine as follows: Sufco - 0.80, Skyline - 0.74,
                    Dugout -1.04;

     "Actual S02" = The weighted average lbs S02/MhlBTU (as received
                    basis) for that Mine (as determined in accordance with
                    ARTICLE IX. SAMPLING AND ANALYSIS) for all Coal shipped
                    for the month from the Mine;

     "Btu2" =       The weighted average as received heat content
                    (as determined in accordance with ARTICLE IX. SAMPLING
                    AND ANALYSIS) for all Coal shipped for the month from
                    the Mine;

     "Value S02" =  The average price of S02 allowances for the
                    month in dollars per ton of S02 determined by summing

XVIII. FORCE MAJEURE

A. Definition of Force Majeure. The term "force majeure" as used in this Agreement shall mean any causes beyond the control and not caused by the fault or negligence of the affected party that the affected party is unable to overcome or mitigate, such as Acts of God, acts of the public enemy, insurrections, riots, strikes, or labor disputes, power, labor or material shortages, fires, explosions, floods, breakdowns of or damage to plants, mines, equipment or facilities, interruptions to or contingencies of transportation, embargoes, court or commission orders, inability to obtain necessary permits, licenses, and governmental approvals after applying for same with reasonable diligence, unforeseen mining conditions, unforeseen geologic faults, or other causes of a similar nature that wholly or partially prevent the mining, loading, and/or delivery of Coal by SELLER from the Mines, or the receiving, unloading or consuming of Coal by BUYER in the generation of electricity at any of units at the Station or other generating stations then receiving Coal under this Agreement, or the transmission of electricity; provided, however, that the excuse of force majeure shall not be available to SELLER if the delay or failure in its performance arises from a defect in the rights entitling SELLER to mine and remove Coal at the Mines. Failure to prevent or settle any strike or labor trouble shall be considered beyond the control of the party claiming such excuse for nonperformance. The party claiming force majeure shall give prompt notice by telephone as soon as possible after the occurrence of the event of force majeure and shall promptly give the other party written notice describing the nature of the occurrence and its probable duration.

B. Suspension of Obligations. Neither party shall be under any obligation nor subject to any liability (except payment of invoices for Coal already delivered) for failure to perform any of its obligations under this Agreement as the result of a force majeure event, and the obligations of the party claiming force majeure shall be suspended to the extent made necessary by such force majeure and during its continuance. Should the situation of a total force majeure at one or more Mine(s) exceed twelve months, the party not claiming force majeure shall have the option to terminate the Mine source(s) under this Agreement upon sixty days written notice.

C. Full or Partial Force Majeure Tonnage Allocation. During the period that an event of force majeure causes a complete reduction in the total quantity of Coal SELLER can deliver from one or more Mines, deliveries shall cease from the affected Mine(s) and shall continue from the unaffected Mine(s) in accordance with the schedule set forth in ARTICLE IV. ORDERING, Section B., from the unaffected Mine(s). During the period that an event of force majeure causes a partial reduction in the total quantity of Coal SELLER can deliver from the affected Mine(s), SELLER first shall continue to deliver Coal from the unaffected Mine(s) in accordance with the schedule set forth in ARTICLE IV. ORDERING, Section B., and then curtail any spot deliveries from the affected Mine(s) that SELLER is not committed to sell. If necessary, SELLER shall apportion the Coal that it is able to deliver from the affected Mine(s) pro rata among the BUYER and all other customers supplied Coal from the affected Mine(s) under existing agreements. During the period that an event of force majeure causes a partial reduction in the total quantity of Coal that BUYER can consume at the Station , BUYER shall apportion its Coal requirements pro rata among SELLER and any other parties with whom BUYER has contracted to supply Coal to the Station. The party not invoking force majeure shall have the right to require the make-up of deliveries suspended during the force majeure, subject to a mutually acceptable scheduling of such make-up deliveries. The price for make-up of such force majeure tonnage shall be as follows:

. If the force majeure was declared by the SELLER, then the price shall be the price in effect at the time the force majeure was declared by the SELLER.

. If the force majeure was declared by the BUYER, then the price shall be the price in effect at the time the Coal deliveries are made up.

16

XIX. AUDIT/ INSPECTION

BUYER, and its authorized agents which have signed appropriate confidentiality agreements with SELLER, at BUYER's risk and expense, shall have the right to make inspections of the properties and related operations of SELLER insofar as may be reasonably required to verify SELLER'S representations and claims relating to the performance of its obligations hereunder. In addition, BUYER or SELLER, upon request, shall furnish the other party and its agents with all information which may be reasonably required to verify quality specifications and to calculate any prices hereunder including verification of any and all passthrough costs. BUYER, upon request to SELLER, at BUYER's risk and expense, shall have the right to verify by audit all information regarding quantity requirements, quality specifications and prices charged hereunder. SELLER shall maintain all such records for a period of twenty-four (24) months from the creation of the records.

XXI. FREEZE CONDITIONING & DUST SUPPRESSION

SELLER shall allow BUYER or its representatives to use BUYER's own equipment or SELLER's equipment to apply freeze conditioning or dust suppressant agents to the Coal supplied herein. The cost of the chemicals used in any such treatment shall be borne by BUYER. At BUYER's option, SELLER shall apply a freeze conditioning or dust suppression agent(s) at a rate (pints per ton) to be specified by the BUYER as the Coal purchased and sold hereunder is loaded into railcars. Such agents shall be approved by BUYER. As full compensation for applying the agents, BUYER shall pay the direct cost of purchasing the agent applied to the Coal purchased and sold hereunder. SELLER shall submit invoices for the agents monthly, which shall be accompanied by documentation satisfactory to BUYER. For billing purposes, SELLER agrees to deduct the weight of any freeze and/or dust conditioning agent from the total weight of each Coal railcar if these chemicals are added prior to weighing the loaded railcar. Specific procedures for determining and administering these weight adjustments will be coordinated among BUYER's Joint Facility Accounting Department, the freeze and/or dust conditioning agent supplier, and SELLER. BUYER will pay invoices within twenty (20) days of receipt of invoices.

For the purpose of calculating the ratios of earnings to fixed charges, "Fixed charges" represent the aggregate of interest charges on short-term and long-term debt and distributions on preferred securities of consolidated subsidiaries, allowance for borrowed funds used during construction (AFUDC) and capitalized interest, and the portion of rental expense deemed to be attributable to interest. "Earnings" represent the aggregate of income (or loss) from continuing operations before obligated mandatorily redeemable preferred securities, income taxes, and fixed charges, less AFUDC and capitalized interest.
