NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. MANAGEMENT'S STATEMENT (SPR, NPC, SPPC)

In the opinion of the management of Sierra Pacific Resources (SPR), Nevada Power Company (NPC), and Sierra Pacific Power Company (SPPC), the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the condensed consolidated financial position, condensed consolidated results of operations and condensed consolidated cash flows for the periods shown. These condensed consolidated financial statements do not contain the complete detail or footnote disclosure concerning accounting policies and other matters which are included in full year financial statements and, therefore, they should be read in conjunction with the audited financial statements included in SPR's, NPC's, and SPPC's Combined Annual Report on Form 10-K for the year ended December 31, 2000.

The results of operations for the three months ended June 30, 2001 are not necessarily indicative of the results to be expected for the full year.

Principles of Consolidation

The condensed consolidated financial statements of SPR include the accounts of SPR and its wholly owned subsidiaries, Nevada Power Company, Sierra Pacific Power Company, (collectively, the "Utilities"), Tuscarora Gas Pipeline Company, Sierra Gas Holding Company (formerly Sierra Energy Company), Sierra Energy Company dba eo three, Sierra Pacific Energy Company, Lands of Sierra, Sierra Pacific Communications, Nevada Electric Investment Company and Sierra Water Development Company. All significant intercompany transactions and balances have been eliminated in consolidation.

Reclassifications

Certain items previously reported for years prior to 2001 have been reclassified to conform to the current year's presentation. Net income and shareholders' equity were not affected by these reclassifications.

Recent Pronouncements

In June 2001, the Financial Accounting Standards Board ("FASB") approved the issuance of three new pronouncements, Statement of Financial Accounting Standards (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. Management does not expect SFAS No. 141, when adopted, to have a material effect on the financial position or results of operations of SPR, NPC, and SPPC. SFAS No. 142, effective for fiscal years beginning after December 15, 2001, 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, when adopted, 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 has not yet determined the impact, if any, of the adoption of SFAS No. 143 on the financial position or results of operations of SPR, NPC, and SPPC.

NOTE 2. FINANCIAL STATEMENTS OF NEVADA POWER COMPANY (NPC)

In accordance with Generally Accepted Accounting Principles, the 1999 merger between SPR and NPC was accounted for as a reverse purchase, with NPC deemed to be the acquirer of SPR 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

This line does not represent any item of revenue or income to which holders of NPC's securities may look for recovery of their investment. This item must be disregarded for determining the ability of NPC to satisfy its obligations or its ability to pay dividends (preferred or common), for calculating NPC's ratios of earnings to fixed charges and preferred dividends and for all of NPC's financial covenants and earnings tests including those under its charter and mortgage.

As in the income statement, the Equity in Earnings of Sierra Pacific Resources reflects the three months of SPR net income, after SPPC preferred stock dividends.

This line item does not represent any item of cash flow to which holders of NPC's securities may look for recovery of their investment. This item must be disregarded for determining the ability of NPC to satisfy its obligations or its ability to pay dividends (preferred or common), for calculating NPC's ratios of earnings to fixed charges and preferred dividends and for all of NPC's financial covenants and earnings tests including those under its charter and mortgage.

NOTE 3. SHORT-TERM BORROWINGS (SPR, NPC, SPPC)

As of January 16, 2001, SPR had eliminated its December 31, 2000, commercial paper balance of $4 million. On March 9, 2001, SPR discontinued its commercial paper program as a result of the establishment of a credit facility, which had an outstanding balance of $50 million at March 31, 2001. That credit facility, which had an expiration date of June 30, 2001, was paid off and terminated on June 12, 2001.

NPC, which had no commercial paper outstanding at December 31, 2000, issued approximately $96.2 million of commercial paper during February and March 2001. By May 25, 2001, NPC had eliminated its commercial paper balances and had no commercial paper outstanding as of June 30, 2001.

SPPC's commercial paper balance increased from $108.9 million at December 31, 2000, to approximately $149.1 million at March 31, 2001. By June 12, 2001, SPPC had eliminated its commercial paper balances and had no commercial paper outstanding as of June 30, 2001. At March 31, 2001, SPPC had a balance of $50.5 million owed to NPC, which was repaid in full on June 12, 2001.

During the quarter ended June 30, 2001, NPC and SPPC each had short-term credit facilities in the amount of $150 million. As of June 30, 2001, the Utilities had not drawn on these facilities. On August 1, 2001, NPC and SPPC each

13

increased the total amount of their short-term credit facilities from $150 million to $250 million and extended the expiration date of their short-term credit facilities from August 27, 2001 to November 30, 2001. These credit facilities serve primarily to back up the Utilities' commercial paper programs and to fund working capital and general corporate needs.

NOTE 4. LONG-TERM DEBT (NPC, SPPC)

On May 24, 2001, NPC issued $350 million of 8.25% General and Refunding Mortgage Bonds, Series A, due June 1, 2011. The bonds were issued under and secured by a General and Refunding Mortgage Indenture dated as of May 1, 2001 that is subject to the prior lien of NPC's Indenture of Mortgage dated as of October 1, 1953. The proceeds of the issuance were used to refinance or discharge outstanding indebtedness including commercial paper, short-term debt, and current maturities of long-term debt.

On June 12, 2001, $150 million of NPC's floating rate notes matured and were paid in full.

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"). 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. (See Note 7 for additional information on the water business sale.) Although SPPC no longer owns the Project, SPPC will continue to bear the obligations and payments for the Bonds under the terms of the Financing Agreement dated as of March 1, 2001, between SPPC and Washoe County, Nevada.

On May 24, 2001, SPPC issued $320 million of its 8.00% General and Refunding Mortgage Bonds, Series A, due June 1, 2008. The bonds were issued under and secured by a General and Refunding Mortgage Indenture dated as of May 1, 2001 that is subject to the prior lien of SPPC's Indenture of Mortgage dated as of December 1, 1940. The proceeds of the issuance were used to refinance or discharge outstanding indebtedness including commercial paper, short-term debt, and current maturities of long-term debt.

On June 12, 2001, $200 million of SPPC's floating rate notes matured and were paid in full.

NOTE 5. EARNINGS PER SHARE (SPR)

SPR follows SFAS No. 128, "Earnings Per Share". The difference between Basic EPS and Diluted EPS is due to common stock equivalent shares resulting from stock options, employee stock purchase plan, performance shares and a non-employee director stock plan. Common stock equivalents were determined using the treasury stock method.

/1/ Because of net losses for the three months ended June 30, 2000, and the six months ended June 30, 2001 and 2000, stock equivalents would be anti-dilutive. Accordingly, Diluted EPS for those periods are computed using the weighted average number of shares outstanding before dilution.

NOTE 6. SEGMENT INFORMATION (SPR)

SPR operates two business segments providing regulated electric and natural gas services. NPC provides electric service to Las Vegas and surrounding Clark County. SPPC provides electric service in northern Nevada and the Lake Tahoe area of California. SPPC also provides natural gas service in the Reno-Sparks area of Nevada. Other segment information includes segments below the quantitative threshold for separate disclosure. In September 2000, SPR and SPPC adopted a plan to sell SPPC's water utility business. The sale of the water utility business was completed on June 11, 2001. Accordingly, the water business is not included in the segment information below.

Information as to the operations 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. Intersegment revenues are not material.

Financial data for business segments is as follows (in thousands):

NOTE 7. DISCONTINUED OPERATIONS (SPR, SPPC)

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 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 refund to customers $21.5 million of the proceeds from the sale. The refund will be credited on the electric bills of SPPC's former water customers over a period not to exceed fifteen months after the close of the sale. 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 were $11.8 million and $15.3 million for the three-month periods ended June 30, 2001, and June 30, 2000, respectively. For the six-month periods ended June 30, 2001, and June 30, 2000,

16

revenues from operations of the water business were $23.2 million and $25.6 million, respectively. The net income from operations of the water business, as shown in the Condensed Consolidated Statements of Income of SPR and SPPC, includes preferred dividends of approximately $100,000 for each of the three-month periods ended June 30, 2001 and 2000, and approximately $200,000 for each of the six-month periods ended June 30, 2001 and 2000. These amounts are not included in the revenues and income (loss) from continuing operations shown in the accompanying income statements.

NOTE 8. REGULATORY EVENTS (SPR, NPC, SPPC)

On April 18, 2001, the Governor of Nevada signed into law AB369. The provisions of AB369 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, AB369 allows the Utilities to recover in future periods their 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 early next year while, at the same time, providing a method for the Utilities to recover their increasing costs for fuel and purchased power. Set forth below is a summary of key provisions of AB369.

Generation Divestiture Moratorium

AB369 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.

AB369 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

AB369 requires both 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. AB369 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, AB369 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.

AB369 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 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.

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 defined below) are just and reasonable and reflect prudent business practices.

17

At June 30, 2001, NPC had a balance of $272.8 million in its deferred energy account, reflecting eligible fuel and purchased power costs incurred since March 1, 2001. At June 30, 2001, SPPC had a balance of $119.2 million in its deferred energy account, which reflects both deferrals in connection with its natural gas business as well as eligible fuel and purchased power costs incurred since March 1, 2001. Management expects these balances to increase significantly during the summer of 2001, particularly at NPC, although the amount of such increases will depend on a number of unpredictable factors such as weather conditions and conditions in the wholesale electricity and gas markets in the western United States.

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 Comprehensive Energy Plan ("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 will not be 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.

AB369 prohibits the PUCN from taking any further action on the CEP described in SPR's Annual Report on Form 10-K for the year ended December 31, 2000, 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

NPC and SPPC are each required to file a general rate application and a deferred energy application on or before the dates listed below:

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.

Restrictions on Mergers and Acquisitions

AB369 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 AB369.

In addition, AB369 includes provisions that would have significantly affected the required regulatory approvals for the proposed acquisition of Portland General Electric Company (PGE) from Enron Corp. On April 26, 2001, Enron Corp. and SPR terminated, by mutual agreement, the proposed purchase and sale of PGE.

Repeal of Electric Industry Restructuring

AB369 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

Senate Bill 372 ("SB372"), 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, both SPPC and NPC 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. SB372 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 energy industry, Assembly Bill 661 ("AB661"). AB661 allows commercial and governmental customers with an average demand greater than 1 megawatt (MW) to select new energy suppliers. The Utilities would continue to provide transmission, distribution, metering and billing services to such customers. AB661 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 cannot be negatively impacted by the departure, and the departing customers must pay any deferred energy fuel balances. 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. AB661 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 in mid-2002.

AB661 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.

FERC Price Cap

On June 19, 2001, the Federal Energy Regulatory Commission ("FERC") adopted a price mitigation plan applicable to 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 Western Systems Coordinating Council for the duration of the mitigation plan. Management is not able to predict at this time the extent to which the FERC price mitigation plan may affect SPR's results of operations. It is possible, however, under certain market conditions, that the FERC plan may adversely affect the availability of spot market power to the Utilities and may reduce the price at which the Utilities can sell power on the wholesale market. SPR recently joined with two utilities in Washington and Oregon to seek changes to the FERC plan on the basis that the price caps are unfair to electric customers who reside outside of California.

NOTE 9. DERIVATIVES AND HEDGING ACTIVITIES (SPR, NPC, SPPC)

Effective January 1, 2001, SPR, SPPC, and NPC adopted the 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.

19

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 8 - Regulatory Events, 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 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 June 30, 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 June 30, 2001, the fair value of the derivatives resulted in the recording of $1.044 billion, $746 million and $298 million in risk management assets and $1.705 billion, $1.055 billion and $645 million in risk management liabilities in the Consolidated Balance Sheets of SPR, NPC and SPPC, respectively. Due to the regulatory environment in which the Utilities operate, regulatory assets and liabilities were established to the extent that electricity and natural gas derivative gains and losses are recoverable or payable through future rates. Accordingly, at June 30 2001, $657 million, $309 million and $348 million in net risk management regulatory assets were recorded in the Consolidated Balance Sheets of SPR, NPC, and SPPC, respectively. In addition, for the six months ended June 30, 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 six months ended June 30, 2001.

The effects of the adoption of SFAS No. 133 on comprehensive income and the components thereof at June 30, 2001, are as follows:

Comprehensive Income  (in $000's)                            SPR         NPC         SPPC

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.

NOTE 10. COMMITMENTS AND CONTINGENCIES (SPR, NPC)

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

20

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 $300 million. As a 14% owner in the Mohave Station, NPC's cost could be $42 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. EPA has solicited information to determine whether visibility impairment in the Grand Canyon can be reasonably attributed to Mohave. If EPA determines that significant visibility impairment is reasonably attributable to the station, EPA could initiate a review for Best Available Retrofit Technology. Mohave's owners believe that settlement of the suit discussed above is acceptable to the EPA. Provisions that are agreed to in a settlement are expected to be reflected in a State Implementation Plan for Nevada and resolve any concerns of the EPA regarding visibility impairment.

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 $20 million.

In July 2000, NPC received from the United States Environmental Protection Agency (EPA) a request 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.

Other Subsidiaries of SPR

Nevada Electric Investment Company (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. It is NEICO's intention to sell the property.

NOTE 11. SUBSEQUENT EVENTS (SPR, SPPC)

On July 20, 2001, SPR's Board of Directors declared a dividend on common stock of 20 cents per share, payable September 15, 2001, to shareholders of record at the close of business on August 24, 2001.

On July 24, 2001, SPR filed with the Securities and Exchange Commission an amended registration statement relating to an offering of 21,850,000 shares of common stock. SPR intends to use the net proceeds to contribute capital to NPC and SPPC to reduce short-term debt obligations and for general corporate purposes, which may include repayment of long-term debt.

On August 3, 2001, NPC issued $115 million principal amount of its First Mortgage Bonds, Series BB and Series CC, to AMBAC Assurance Corporation ("AMBAC") in satisfaction of a covenant contained in insurance agreements entered into with AMBAC in June and July 2000, in connection with the issuance by Clark County, Nevada of tax-exempt bonds for the benefit of NPC. These First Mortgage Bonds secure NPC's reimbursement obligations under the insurance agreements with AMBAC.

On August 7, 2001, SPPC declared $975,000 ($0.4875 per share) in dividends to holders of its preferred stock. The dividend is payable on September 1, 2001, to holders of record as of August 10, 2001.

On August 7, 2001, NPC declared a $33 million dividend on its common stock, all of which is held by SPR.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information in this Form 10-Q 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, pending or future Nevada, California or federal legislation, 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 Nevada Power Company (NPC), Sierra Pacific Power Company (SPPC) (collectively, the "Utilities"), or Sierra Pacific Resources (SPR), to differ materially from those contemplated in any forward-looking statement include, among others, the following:

(1) the outcome and timing of rate cases to be filed by NPC and SPPC 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 which 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 extent to which high energy prices and the financial difficulties of electric utilities and power exchanges in the western United States cause any counterparties to NPC's or SPPC's purchased power contacts to default on their obligations, thus requiring the Utilities to seek to replace the power on the spot market;

(3) the effect of price controls promulgated in June 2001 by the Federal Energy Regulatory Commission (FERC) on the availability and price of wholesale power purchases and sales in the western United States;

(4) the ability of SPR, NPC and SPPC to access the capital markets to support their requirements for working capital, construction costs and the repayment of maturing debt;

(5) 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;

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

(7) 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;

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

(9) the loss of any significant customers;

(10) 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 NPC or SPPC;

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

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

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

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

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

22

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.

SIERRA PACIFIC RESOURCES

During the first six months of 2001, SPR incurred a loss of $54.6 million from continuing operations before preferred stock dividend requirements. However, for the three months ended June 30, 2001, SPR earned $28.4 million from continuing operations before preferred stock dividend requirements. During the first six months of 2001, SPR paid $19.8 million in common stock dividends. NPC and SPPC, SPR's principal subsidiaries, paid common stock dividends of $0 and $76 million, respectively, to their parent, SPR. SPPC also paid $1.95 million in dividends to holders of its preferred stock.

As discussed in the results of operations sections that follow, operating results for the first six months of 2001 were negatively affected by the significantly higher and extremely volatile fuel and purchased power costs that developed in the western United States in May 2000 and have continued since.

In an effort to mitigate the effects of higher fuel and purchased power costs, during 2000 NPC and SPPC (collectively, the "Utilities") entered into the Global Settlement, which established a mechanism that initiated incremental rate increases for each Utility. However, because the mechanism for adjusting rates lagged changes in actual energy costs and was subject to certain caps, increases were insufficient to cover fuel and purchased power costs. Cumulative electric rate increases under the Global Settlement for NPC and SPPC, respectively, are $127 million and $65 million per year.

Because the rate adjustment mechanism of the Global Settlement 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.

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. As described in more detail below, in April 2001 the Nevada Legislature enacted AB369, the provisions of which include the reinstatement of deferred energy accounting by the Utilities beginning March 1, 2001. Deferred energy accounting allows the Utilities 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.

NEVADA ENERGY LEGISLATION

On April 18, 2001, the Governor of Nevada signed into law AB369. The provisions of AB369 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, AB369 allows the Utilities to recover in future periods their 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 early next year while, at the same time, providing a method for the Utilities to recover their increasing costs for fuel and purchased power. Set forth below is a summary of key provisions of AB369.

Generation Divestiture Moratorium

AB369 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.

AB369 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.

23

Deferred Energy Accounting

AB369 requires both 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. AB369 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, AB369 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.

AB369 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 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.

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 are just and reasonable and reflect prudent business practices.

At June 30, 2001, NPC had a balance of $272.8 million in its deferred energy account, reflecting eligible fuel and purchased power costs incurred since March 1, 2001. At June 30, 2001, SPPC had a balance of $119.2 million in its deferred energy account, which reflects both deferrals in connection with its natural gas business as well as eligible fuel and purchased power costs incurred since March 1, 2001. Management expects these balances to increase significantly during the summer of 2001, particularly at NPC, although the amount of such increases will depend on a number of unpredictable factors such as weather conditions and conditions in the wholesale electricity and gas markets in the western United States.

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 will not be 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.

AB369 prohibits the PUCN from taking any further action on the CEP described in SPR's Annual Report on Form 10-K for the year ended December 31, 2000, 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

NPC and SPPC are each required to file a general rate application and a deferred energy application on or before the dates listed below:

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.

Restrictions on Mergers and Acquisitions

AB369 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 AB369.

In addition, AB369 includes provisions that would have significantly affected the required regulatory approvals for the proposed acquisition of Portland General Electric Company (PGE) from Enron Corp. On April 26, 2001, Enron Corp. and SPR terminated, by mutual agreement, the proposed purchase and sale of PGE.

Repeal of Electric Industry Restructuring

AB369 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

SB372, 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, both SPPC and NPC 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. SB372 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 energy industry, AB661. AB661 allows commercial and governmental customers with an average demand greater than 1 megawatt (MW) to select new energy suppliers. The Utilities would continue to provide transmission, distribution, metering and billing services to such customers. AB661 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 cannot be negatively impacted by the departure, and the departing customers must pay any deferred energy fuel balances. 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. AB661 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 in mid-2002.

25

AB661 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.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

On April 13, 2001, SPR announced that it would not be paying the dividend on its common stock historically paid on May 1st. On July 20, 2001, SPR's Board of Directors declared a dividend on common stock of 20 cents per share, payable September 15, 2001, to shareholders of record at the close of business on August 24, 2001. Payment of future dividends will be determined by SPR's Board of Directors and will be subject to factors that ordinarily affect dividend policy, such as earnings, cash flow, estimates of future earnings and cash flow, business conditions, regulatory factors, financial condition, and other matters.

On July 24, 2001, SPR filed with the Securities and Exchange Commission an amended registration statement relating to an offering of 21,850,000 shares of common stock. SPR intends to use the net proceeds to contribute capital to NPC and SPPC to reduce short-term debt obligations and for general corporate purposes, which may include repayment of long-term debt.

During the quarter ended June 30, 2001, NPC and SPPC each had short-term credit facilities in the amount of $150 million. As of June 30, 2001, the Utilities had not drawn on these facilities. On August 1, 2001, NPC and SPPC each increased the total amount of their short-term credit facilities from $150 million to $250 million and extended the expiration date of their short-term credit facilities from August 27, 2001 to November 30, 2001. These credit facilities serve primarily to back up the Utilities' commercial paper programs and to fund working capital and general corporate needs.

Set forth below is a schedule showing the current maturities of debt during the remainder of 2001 (in $000's):

The Utilities expect to pay the principal amounts of these maturing debt obligations, to pay their current obligations and to finance the anticipated deferred energy regulatory assets with a combination of ongoing cash flows from operations and the proceeds from borrowings and the sale of additional securities.

The Utilities expect that their working capital financing needs will grow with the restoration of deferred energy accounting. To the extent that current revenues are less than current expenses, the recovery of those costs will be delayed until the completion of the next deferred rate cases.

It is Management's objective to achieve a ratio of common equity to total capitalization of 30% to 35% over the long term. Accordingly, Management believes that SPR may be required to issue additional securities in the future in order to achieve this objective, although the exact amounts and timing cannot be predicted at this time.

Residential electric revenues increased for the three and six months ended June 30, 2001, over the same periods in 2000 due to increases in both electric rates and the number of customers. Higher rates resulted from cumulative monthly rate increases pursuant to the 2000 Global Settlement and an increase in rates effective March 1, 2001, pursuant to the CEP. For the three and six month periods ended June 30, 2001, the number of residential customers increased by 4.9% and 5.0%, respectively, over the same periods in 2000.

Commercial and industrial electric revenues also increased for the three and six months ended June 30, 2001, over the same periods in 2000 due to increases in both electric rates and the number of customers. Commercial and industrial rate increases corresponded to those experienced by residential customers. The opening of several new schools and large casinos contributed to the increases in commercial and industrial revenues, diminishing the effect of voluntary energy curtailment practices among these customer classes. For both the three and six month periods ended June 30, 2001, the number of commercial customers increased by 4.4% over the same periods of 2000. For the three and six month periods ended June 30, 2001, the number of industrial customers increased by 7.7% and 8.0%, respectively, over the same periods in 2000.

The large increases in other electric revenues for the three and six-month periods ended June 30, 2001, over the same periods in 2000 were mainly due to significant increases in risk management activities and wholesale power sales at much higher prices. NPC seeks neither to purchase nor sell energy on a speculative basis. NPC purchases fixed cost energy at a delivery point where the energy can either be delivered to its control area or sold, should NPC not require the energy. The energy is also sold if replacement energy can be obtained less expensively than transporting the energy to the control area. Fewer of these sales have taken place in prior years.

Purchased power costs were significantly higher for both the three and six months ended June 30, 2001, than for the same periods of the prior year, as Short-Term Firm and spot market prices, as well as volumes purchased, increased substantially. NPC acquired a portfolio of energy supply contracts sufficient to meet the projected needs of its retail customers in advance of the peak summer period. From time to time and dependent, in part, upon the weather, NPC may sell purchased or generated power on the wholesale market to the extent that supplies exceed the actual energy demands of its retail customers. The benefit of such sales is passed to NPC's retail customers through reduced costs per MWH.

Deferral of energy costs-net decreased significantly for both the three and six months ended June 30, 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 the three and six month periods ended June 30, 2000, as a result of deferred energy rate increases granted in 1999.

Other operating expense for the three-month period ending June 30, 2001, decreased compared with the prior year, as the 2000 amount included nonrecurring executive severance expenses and timing differences in employee benefit expenses. The decrease was offset in part by a current year increase in costs associated with the Clark Station. Other operating expense for the six-month period ending June 30, 2001, increased compared to the same period in 2000 primarily due to a $16.1 million increase in the provision for uncollectible accounts related to the California Power Exchange and a $3 million reserve provision established as a result of AB369.

Maintenance costs for the three- and six-month periods ending June 30, 2001, increased from the prior year as a result of additional outages at the Reid-Gardner, Mohave, and Clark stations and unplanned maintenance expenses. A shift from generation divestiture activities in 2000 to maintenance activities in 2001 also contributed to the increase.

The increases in depreciation and amortization expense for the three and six-month periods ended June 30, 2001, compared to the same periods in 2000, reflect an increase in plant-in-service over the prior year.

For the three-month period ending June 30, 2001, income tax expense replaced an income tax benefit in the same period of 2000 as NPC recorded pre-tax income for the current year period compared with a pre-tax loss for the year-earlier period. However, for the six-months ended June 30, 2001, the income tax benefit increased over the prior year as a result of a larger pre-tax loss in the current year than in 2000.

Interest charges on long-term debt increased for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 due primarily to the issuance of a total of $250 million in floating rate notes in June and August of 2000, and the issuance of $350 million in mortgage bonds in May 2001.

Interest charges-other decreased for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 due to reduced reliance on commercial paper in 2001.

The increase in Other income (expense) - net for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 is due primarily to the recognition in the current year of the carrying charge on deferred fuel and purchased power balances pursuant to AB369.

Financial Condition, Liquidity and Capital Resources

During the first six months of 2001, NPC incurred a loss of approximately $22.3 million (excluding NPC's equity in the losses of its parent, SPR), and declared no dividends on its common stock, all of which is held by SPR. However, for the three months ended June 30, 2001, NPC earned $33.0 million (excluding NPC's equity in the earnings of its parent, SPR). In June 2001 NPC received a $21.9 million capital contribution from SPR.

Net cash flows during the six months ended June 30, 2001, were comparable to the same period in 2000. However, net cash flows from operating activities, decreased significantly. This was the result of the combination of a larger loss before preferred dividends and large increases in accounts receivable and deferred energy costs due to increased risk management activities and implementation of AB369, respectively, being only partially offset by an increase in accounts payable. Cash

29

flows from financing activities increased significantly in 2001 compared to 2000 due to a greater net increase in long-term debt in 2001, a decrease in short-term borrowings in 2000, and no common dividend payment in 2001. These increases were offset in part by a decrease in funding from NPC's parent, SPR, from $128 million in 2000 to $21.9 million in 2001.

Construction Expenditures and Financing

NPC's construction program and capital requirements for the period 2001-2005 were originally discussed in its Annual Report on Form 10-K for the year ended December 31, 2000. Of NPC's amount projected for 2001 ($175 million), $88.9 million (50.8%) was spent as of June 30, 2001. Construction expenditures were funded from sources other than internally generated funds.

NPC may utilize internally generated cash, the proceeds from secured and unsecured borrowings and preferred securities, and capital contributions from SPR to meet capital expenditure requirements through 2001.

Retail electric revenues increased for both the three and six-month periods ended June 30, 2001, over the same periods in 2000 due to increases in rates offsetting small reductions in demand. Higher rates resulted from cumulative monthly rate increases pursuant to the 2000 Global Settlement and an increase in rates effective March 1, 2001, pursuant to the CEP. Demand by commercial and industrial customers decreased in part from voluntary curtailment programs, which were offset by continued growth in the number of customers. Demand by residential customers increased due to 10% increases in both heating degree-days and cooling degree-days.

The large increases in other electric revenues for the three and six-month periods ended June 30, 2001, over the same periods in 2000 were mainly due to significant increases in risk management activities and wholesale power sales at much higher prices. SPPC seeks neither to purchase nor sell energy on a speculative basis. SPPC purchases fixed cost energy at a

31

delivery point where the energy can either be delivered to its control area or sold, should SPPC not require the energy. The energy is also sold if replacement energy can be obtained less expensively than transporting the energy to the control area. Fewer of these sales have taken place in prior years.

The three months ended June 30, 2001, reflected increased gas revenues from residential and commercial customers compared to the prior year, primarily as a result of the rate increase approved by the PUCN that took effect February 1, 2001. The increase in retail revenues was due, to a lesser extent, to an increase in heating-degree days.

SPPC's wholesale gas revenues increased significantly for the six months ended June 30, 2001, and increased approximately 15% for the second quarter, over the same periods in 2000 in response to risk management activities. SPPC seeks neither to purchase nor sell gas on a speculative basis.

Purchased power costs were higher for both the three and six-month periods ended June 30, 2001, than the prior year because SPPC fulfilled more of its total energy requirements with more expensive Short-Term Firm purchased power. SPPC also engaged in additional risk management activities at prices that were substantially higher.

The cost of retail gas purchased for resale increased for the three and six-month periods ended June 30, 2001, compared to the prior year due to substantially higher gas prices. The increase in the cost of wholesale gas purchased over the prior year reflects higher prices as well as costs associated with risk management activities.

For both the three and six months ended June 30, 2001, SPPC recorded significant Deferral of energy costs-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.

Deferral of energy costs-net for gas purchased for resale increased substantially for both the three and six month periods ended June 30, 2001, over the prior year because SPPC is recording higher undercollections of such costs than in 2000. Revenue received from the base purchased gas rates did not cover the increased cost of natural gas experienced by SPPC.

Other operating expense for the three-month period ending June 30, 2001, decreased compared with the prior year, as the 2000 amount included nonrecurring executive severance expenses and timing differences in employee benefit expenses. Other operating expense for the six-month period ending June 30, 2001, increased compared to the same period in 2000 primarily due to a $3.5 million increase in the provision for uncollectible accounts related to the California Power Exchange and a $2.7 million reserve provision established as a result of AB369. The increase was offset, in part, by reductions in labor costs, and consulting and legal fees.

Maintenance costs for the three and six-month periods ended June 30, 2001 were higher compared to the same periods in 2000 primarily due to increased expenses related to the combustion turbines at the Winnemucca and Clark Mountain generation facilities.

Income taxes were higher for the three-month period ending June 30, 2001, compared to the prior year reflecting an increase in pre-tax income from continuing operations. However, for the six-months ended June 30, 2001, an income tax benefit replaced income tax expense in the same period of 2000 as SPPC recorded a pre-tax loss from continuing operations for the current year period compared with pre-tax income from continuing operations for the year-earlier period.

Interest charges on long-term debt increased for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 due primarily to the issuance of $200 million in floating rate notes in June of 2000, and the issuance of $320 million in mortgage bonds in May 2001.

Interest charges-other decreased for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 due to reduced reliance on commercial paper in 2001.

The change in Other income (expense) - net from net expense to net income for the three- and six-month periods ending June 30, 2001, compared to the same periods of 2000 is due primarily to the recognition in the current year of the carrying charge on deferred fuel and purchased power balances pursuant to AB369.

Financial Condition, Liquidity and Capital Resources

During the first six months of 2001, SPPC incurred a loss of $151,000 from continuing operations before preferred stock dividends. However, for the three months ended June 30, 2001, SPPC earned $3.8 million from continuing operations before preferred stock dividends. During the first six months of 2001, SPPC paid $1.95 million in dividends to holders of its preferred stock and paid $76 million in dividends on its common stock, all of which is held by its parent, SPR. In June 2001 SPPC received a $4.9 million capital contribution from SPR.

Net cash flows during the six months ended June 30, 2001, were comparable to the same period in 2000 as a result of an increase in net cash flows from investing activities offsetting decreases in net cash flows from both operating activities and financing 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 net cash flows from operating activities in 2001 compared to 2000 was primarily the result of increases in accounts receivable and deferred energy costs due to increased risk management activities and implementation of AB369, respectively. The decrease in cash flows from financing activities was mainly due to a decrease in net long-term debt issued and an increase in common dividends paid in 2001.

Construction Expenditures and Financing

SPPC's construction program and capital requirements for the period 2001-2005 were originally discussed in its Annual Report on Form 10-K for the year ended December 31, 2000. Of SPPC's amount projected for 2001 ($125 million), $57.5 million (46.0%) was spent as of June 30, 2001. Construction expenditures were funded from sources other than internally generated funds.

SPPC may utilize internally generated cash, the proceeds from secured and unsecured borrowings and preferred securities, and capital contributions from SPR to meet capital expenditure requirements through 2001.

Sierra Pacific Resources (Holding Company)

The Condensed Consolidated Statements of Income of Sierra Pacific Resources include the operating results of the holding company. The holding company operating results included a charge of approximately $22 million recognized as a result of the termination of the PGE acquisition. The holding company also recognized higher interest costs, $27.8 million in 2001 and $17.2 million in 2000, due to the issuance of a total of $600 million in debt in April and May of 2000.

Tuscarora Gas Pipeline Company

The Condensed Consolidated Statements of Income of Sierra Pacific Resources include the operating results of Tuscarora Gas Pipeline Company (TGPC), a wholly owned subsidiary of SPR. For the three-and six-month periods ended June 30, 2001, TGPC contributed $.6 million and $1.3 million, respectively, in net income. For the three-and six-month periods ended June 30, 2000, TGPC contributed $.5 million and $1.1 million, respectively, in net income.

e-three

The Condensed Consolidated Statements of Income of Sierra Pacific Resources include the operating results of e-three, a wholly owned subsidiary of SPR. For the three months ended June 30, 2001, e-three contributed $.2 million in net income; e-three incurred a net loss of $.1 million for the six months ended June 30, 2001. For the three-and six-month periods ended June 30, 2000, e-three contributed $.1 million and $.3 million, respectively, in net income.

Sierra Pacific Energy Company

The Condensed Consolidated Statements of Income of Sierra Pacific Resources include the operating results of Sierra Pacific Energy Company (SPE), a wholly owned subsidiary of SPR. For the three- and six-month periods ended June 30, 2001, SPE incurred net losses of $71,000 and $158,000, respectively. SPE incurred net losses of $.5 million and $3.8 million, respectively, for the three- and six-month periods ended June 30, 2000. The losses are the result of costs incurred to exit the retail energy-sales business.

Sierra Pacific Communications

The Condensed Consolidated Statements of Income of Sierra Pacific Resources include the operating results of Sierra Pacific Communications (SPC), a wholly owned subsidiary of SPR. For the three- and six-month periods ended June 30, 2001,

35

SPC incurred net losses of $396,000 and $769,000, respectively. SPC incurred net losses of $14,000 and $75,000, respectively, for the three- and six-month periods ended June 30, 2000.

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 which Enron Corp and PGE had incurred for the proposed transaction. The Condensed Consolidated Statement of Income of SPR for the six months ended June 30, 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.

GENERATION DIVESTITURE

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. For additional information, see the Annual Report on Form 10-K for the year ended December 31, 2000.

As described above, AB369, 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 California Public Utilities Commission (CPUC) to divest its plants was denied, subject to future refiling.

As a result of these legislative and regulatory developments, the Utilities are engaged in discussions with the buyers of the generation assets regarding the termination of the sales agreements and the related energy buyback contracts and interconnection agreements. As of June 30, 2001, NPC and SPPC incurred costs of approximately $9.5 million and $13.8 million, respectively, in order to prepare for the sale of generation assets. NPC and SPPC plan to request recovery of these costs.

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 will be credited on the electric bills of SPPC's former water customers over a period not to exceed fifteen months after the close of the sale. 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 sale for an additional $8 million will require action by the CPUC. The sale agreement contemplates a second closing for the hydroelectric facilities to accommodate the CPUC's review of the transaction. Not included in the sale was certain property 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.

REGULATORY MATTERS

Substantially all of the utility operations of both Utilities are conducted in Nevada. As a result both companies are subject to utility regulation within Nevada and, therefore, deal with many of the same regulatory issues.

FERC Matters (NPC, SPPC)

Price Mitigation Plan

On June 19, 2001, the FERC adopted a price mitigation plan applicable to 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 Western Systems Coordinating Council for the duration of the mitigation plan.

36

The Utilities are not able to predict at this time the extent to which the FERC price mitigation plan may affect their results of operations. It is possible, however, under certain market conditions, that the FERC plan may adversely affect the availability of spot market power to the Utilities and may reduce the price at which the Utilities can sell power on the wholesale market. SPR recently joined with two utilities in Washington and Oregon to seek changes to the FERC plan on the basis that the price caps are unfair to electric customers who reside outside of California.

Regional Transmission Organization and Independent Transmission Company

NPC and SPPC are members of a proposed regional transmission organization (RTO West) and a proposed independent transmission company (TransConnect). On April 25, 2001, FERC gave preliminary approval for both RTO West and TransConnect. Both organizations remain subject to approvals from state regulators and the board of directors of each member company. See the Utilities' Annual Report on Form 10-K for the year ended December 31, 2000, for additional information about RTO West and TransConnect.

Wholesale Sales Tariffs

On March 13, 2001, SPPC and NPC 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.

Nevada Matters

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, NPC and SPPC 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.

Finance Authority (NPC, SPPC)

On June 19, 2001, NPC and SPPC filed with the PUCN asking for approval to issue long or short-term debt on either a secured or unsecured basis in an aggregate amount not to exceed $200 million and $100 million, respectively, through the end of 2002. The Utilities also filed on 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 application the Utilities have 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.

Natural Gas Rate Increase (SPPC)

On June 29, 2001, SPPC filed with the PUCN a request seeking a natural gas rate increase. The Purchase Gas Adjustment (PGA) filing was made requesting an increase in gas rates of $63 million annually. If the increase is granted, an average residential customer's monthly bill will increase by approximately 55% or $27.43.

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. SPPC has asked that the rate become effective August 1, 2001. Phase Two, which is scheduled to be filed with the CPUC in January 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

37

Clause, which would allow SPPC to file for periodic rate adjustments to reflect its actual costs for wholesale energy supplies. Phase Two will also include a proposal pertaining to the termination of the 10% rate reduction mandated by AB 1890, and a modification of the distribution performance ratemaking mechanism (PBR) previously agreed to by all parties.

Distribution Performance-based Rate-making (PBR)

Hearings on SPPC's distribution 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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES
ABOUT MARKET RISK

See SPR's Annual Report on Form 10-K for the year ended December 31, 2000, for quantitative and qualitative disclosures about market risk. There have been no material changes to the information previously disclosed in that report, except as described in the following discussion.

The Utilities described in their Annual Report on Form 10-K for the year ended December 31, 2000, that they were primarily exposed to commodity price risk for changes in the market price of electricity as well as changes in fuel costs incurred to generate electricity. However, on April 18, 2001, the Governor of Nevada signed into law AB369, which provides, among other requirements, a reinstatement of deferred energy accounting for electric utilities. AB369 requires both Utilities to utilize 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. To the extent actual fuel and purchased power costs exceed amounts collected through rates, deferred energy accounting provides a mechanism to collect the excess amounts through adjustments to rates in future time periods, subject to PUCN review of prudency and other matters. The Utilities are also permitted to record a carrying charge on uncollected deferred balances. Deferred energy accounting significantly affects the commodity price risk associated with the Utilities' purchased power and fuel costs. See "Nevada Energy Legislation" in Item 2, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, above, for more information regarding deferred energy accounting and AB369.

Also See Item 2, Management's Discussion And Analysis Of Financial Condition And Results Of Operations, above, for a discussion of rate increases permitted under the Global Settlement and the CEP, and the estimated future revenues that will be provided by those increases.

PART II

ITEM 1. LEGAL PROCEEDINGS

As discussed in SPR's Annual Report on Form 10-K for the year ending December 31, 2000, Sierra Touch America LLC ("STA"), is a partnership between SPR's wholly owned subsidiary, Sierra Pacific Communications ("SPC"), and Touch America, a subsidiary of Montana Power Company. STA is constructing and will operate a fiber optic line between Salt Lake City, Utah and Sacramento, CA. SPC's share is approximately $25 million of a total estimated construction cost of $130 million. Williams Communications, LLC ("Williams") has filed a complaint in United States District Court alleging that STA has failed to make timely payment on invoices totaling $23.4 million in connection with a construction agreement between Williams and STA whereby Williams is to construct a fiber optic telecommunications route. STA has not approved certain payments because of questions about invoicing and the quality of work performed by Williams. Although SPC's ultimate liability, if any, in this matter is presently difficult to estimate, Management believes that the final outcome is not likely to have a material adverse effect on SPR's financial position.

Although SPR, NPC, and SPPC are involved in other ongoing litigation on a variety of matters, in management's opinion none individually or collectively are material to SPR's, NPC's, or SPPC's financial position.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

The 2001 Annual Meeting of the Shareholders of Sierra Pacific Resources was held on May 21, 2001. SPR solicited proxies pursuant to Regulation 14 under the Securities and Exchange Act of 1934.

20

the Company's books of account), for the purpose of determining the extent to which fungible properties, or other properties not otherwise identified, reflected in the same generic account or subaccount in the Company's books of account constitute Funded Property or Funded Property retired.

(i) there shall be deducted from the Cost or Fair Value to the Company thereof, as the case may be (as of the date so certified), an amount equal to the Cost (or as to Property Additions of which the Fair Value to the Company at the time the same became Funded Property was certified to be an amount less than the Cost as determined pursuant to this Section, then such Fair Value, as so certified, in lieu of Cost) of all Funded Property of the Company retired to the date of such certification (other than the Funded Property, if any, in connection with the application for the release of which such certificate is filed) and not theretofore deducted from the Cost or Fair Value to the Company of Property Additions theretofore certified to the Trustee, and

(ii) there may, at the option of the Company, be added to such Cost or Fair Value, as the case may be, the sum of

(A) the principal amount of any obligations secured by Purchase Money Lien, not theretofore so added and which the Company then elects so to add, which shall theretofore have been delivered to the Trustee or the

21

trustee or other holder of a Lien prior to the Lien of this Indenture as the basis of the release of Funded Property retired from the Lien of this Indenture or such prior Lien, as the case may be;

(B) ten-sevenths (10/7) of the amount of any cash, not theretofore so added and which the Company then elects so to add, which shall theretofore have been delivered to the Trustee or the trustee or other holder of a Lien prior to the Lien of this Indenture as the proceeds of insurance on Funded Property retired (to the extent of the portion thereof deemed to be Funded Cash) or as the basis of the release of Funded Property retired from the Lien of this Indenture or from such prior Lien, as the case may be;

(C) ten-sevenths (10/7) of the principal amount of any Security or Securities, or portion of such principal amount, not theretofore so added and which the Company then elects so to add, (I) which shall theretofore have been delivered to the Trustee as the basis of the release of Funded Property retired or (II) the right to the authentication and delivery of which under the provisions of Section 4.03 shall at any time theretofore have been waived under Section 8.03(d)(iii) as the basis of the release of Funded Property retired;

(D) the Cost or Fair Value to the Company (whichever shall be less), after making any deductions and any additions pursuant to this Section, of any Property Additions, not theretofore so added and which the Company then elects so to add, which shall theretofore have been made the basis of the release of Funded Property retired (such Fair Value to be the amount shown in the Expert's Certificate delivered to the Trustee in connection with such release); and

(E) the Cost to the Company of any Property Additions (including Property Additions subject to the Lien of the NVP 1953 Mortgage) not theretofore so added and which the Company then elects so to add, to the extent that the same shall have been substituted for Funded Property retired;

provided, however, that the aggregate of the amounts added under clause
(ii) above shall in no event exceed the amounts deducted under clause
(i) above.

(c) Except as otherwise provided in Section 8.03, the term "Cost" with respect to Property Additions shall mean the sum of (i) any cash delivered in payment therefor or for the acquisition thereof, (ii) an amount equivalent to the fair market value in cash (as of the date of delivery) of any securities or other property delivered in payment therefor or for the acquisition thereof, (iii) the principal amount of any obligations secured by prior Lien (other than the NVP 1953 Mortgage) upon such Property Additions outstanding at the time of the acquisition thereof, (iv) the principal amount of any other obligations incurred or assumed in connection with the payment for such Property Additions or for the acquisition thereof and (v) any other amounts which, in accordance with generally accepted accounting principles, are properly charged or chargeable to the plant or other property accounts of the Company with respect to such Property Additions as part of the cost of construction or acquisition thereof, including, but not limited to,

22

any allowance for funds used during construction or any similar or analogous amount; provided, however, that, notwithstanding any other provision of this Indenture,

(x) with respect to Property Additions owned by a successor corporation immediately prior to the time it shall have become such by consolidation or merger or acquired by a successor corporation in or as a result of a consolidation or merger (excluding, in any case, Property Additions owned by the Company immediately prior to such time), Cost shall mean the amount or amounts at which such Property Additions are recorded in the plant or other property accounts of such successor corporation, or the predecessor corporation from which such Property Additions are acquired, as the case may be, immediately prior to such consolidation or merger;

(y) with respect to Property Additions which shall have been acquired (otherwise than by construction) by the Company without any consideration consisting of cash, securities or other property or the incurring or assumption of indebtedness, no determination of Cost shall be required, and, wherever in this Indenture provision is made for Cost or Fair Value, Cost with respect to such Property Additions shall mean an amount equal to the Fair Value to the Company thereof or, if greater, the aggregate amount reflected in the Company's books of account with respect thereto upon the acquisition thereof; and

(z) in no event shall the Cost of Property Additions be required to reflect any depreciation or amortization in respect of such Property Additions, or any adjustment to the amount or amounts at which such Property Additions are recorded in plant or other property accounts due to the non-recoverability of investment or otherwise.

If any Property Additions are shown by the Expert's Certificate provided for in Section 4.02 (b)(ii) to include property which has been used or operated by others than the Company in a business similar to that in which it has been or is to be used or operated by the Company, the Cost thereof need not be reduced by any amount in respect of any goodwill, going concern value rights and/or intangible property simultaneously acquired for which no separate or distinct consideration shall have been paid or apportioned, and in such case the term Property Additions as defined herein may include such goodwill, going concern value rights and intangible property.

SECTION 1.05 Content and Form of Documents Delivered to Trustee.

(a) Any Officer's Certificate may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and, insofar as it relates to or is dependent upon matters which are subject to verification by Accountants, upon a certificate or opinion of, or representations by, an Accountant, and, insofar as it relates to or is dependent upon matters which are required in this Indenture to be covered by a certificate or opinion of, or representations by, an Expert, upon the certificate or opinion of, or representations by, an Expert, unless, in any case, such officer has actual knowledge that the certificate or opinion or representations with respect to the matters upon which such Officer's Certificate may be based as aforesaid are erroneous.

Any Expert's Certificate may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company and which are not subject to verification by Experts, upon a certificate or opinion of, or representations by, an officer or officers of the Company, unless such Expert has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion may be based as aforesaid are erroneous.

Any certificate of an Accountant may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company and which are not subject to verification by Accountants, upon a certificate of, or representations by, an officer or officers of the Company, unless such Accountant has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion may be based as aforesaid are erroneous.

24

Any Opinion of Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company, upon a certificate of, or representations by, an officer or officers of the Company, and, insofar as it relates to or is dependent upon matters which are subject to verification by Accountants upon a certificate or opinion of, or representations by, an Accountant, and, insofar as it relates to or is dependent upon matters required in this Indenture to be covered by a certificate or opinion of, or representations by, an Expert, upon the certificate or opinion of, or representations by, an Expert, unless such counsel has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his opinion may be based as aforesaid are erroneous. In addition, any Opinion of Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon matters covered in an Opinion of Counsel rendered by other counsel, upon such other Opinion of Counsel, unless such counsel has actual knowledge that the Opinion of Counsel rendered by such other counsel with respect to the matters upon which his Opinion of Counsel may be based as aforesaid are erroneous.

(b) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

(c) Whenever, subsequent to the receipt by the Trustee of any Board Resolution, Officer's Certificate, Expert's Certificate, Net Earnings Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or instrument may be substituted therefor in corrected form with the same force and effect as if originally filed in the corrected form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding, if any such corrective

25

document or instrument indicates that action has been taken by or at the request of the Company which could not have been taken had the original document or instrument not contained such error or omission, the action so taken shall not be invalidated or otherwise rendered ineffective but shall be and remain in full force and effect, except to the extent that such action was a result of willful misconduct or bad faith. Without limiting the generality of the foregoing, any Securities issued under the authority of such defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefit of the Lien of this Indenture equally and ratably with all other Outstanding Securities, except as aforesaid.

SECTION 1.06 Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the record of Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article XV, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 11.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders shall be proved in the manner provided in Section 15.06.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be proved in any other manner which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

(c) The principal amount (except as otherwise contemplated in clause (y) of the first proviso to the definition of Outstanding) and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of a Holder shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

26

(e) Until such time as written instruments shall have been delivered to the Trustee with respect to the requisite percentage of principal amount of Securities for the action contemplated by such instruments, any such instrument executed and delivered by or on behalf of a Holder may be revoked with respect to any or all of such Securities by written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven.

(f) Securities of any series, or any Tranche thereof, authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

(g) The Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or other Act solicited by the Company, but the Company shall have no obligation to do so. In addition, the Trustee may, at its option, fix in advance a record date for the determination of Holders entitled to join in the giving or making of any Notice of Default, any declaration of acceleration referred to in Section 10.02, any request to institute proceedings referred to in Section 10.11 or any direction referred to in Section 10.16. If any such record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act, or such notice, declaration, request or direction, may be given before or after such record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for the purposes of determining (i) whether Holders of the requisite proportion of the Outstanding Securities have authorized or agreed or consented to such Act (and for that purpose the Outstanding Securities shall be computed as of the record date) and/or (ii) which Holders may revoke any such Act (notwithstanding subsection (e) of this Section).

SECTION 1.07 Notices, Etc. to Trustee and Company.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

Any notice required by this Indenture may be waived in writing by the Person entitled to receive such notice, either before or after the event otherwise to be specified therein, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 1.09 Conflict with Trust Indenture Act.

This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable and except to the extent that the law of any jurisdiction wherein any portion of the Mortgaged Property is located shall mandatorily govern the creation of a mortgage lien on and security interest in, or perfection, priority or enforcement of the Lien of this Indenture or exercise of remedies with respect to, such portion of the Mortgaged Property.

SECTION 1.15 Legal Holidays.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities other than a provision in Securities of any series, or any Tranche thereof, or in the indenture supplemental hereto, Board Resolution or Officer's Certificate which establishes the terms of the Securities of such series or Tranche, which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal and premium, if any, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day.

SECTION 1.16 Investment of Cash Held by Trustee.

Any cash held by the Trustee or any Paying Agent under any provision of this Indenture shall, except as otherwise provided in Section 8.06 or in Article IX, at the request of the Company evidenced by Company Order, be invested or reinvested in Investment Securities designated by the Company (such Company Order to contain a representation to the effect that the securities designated therein constitute Investment Securities), and any interest on such Investment Securities shall be promptly paid over to the Company as received free and clear of any Lien. Such Investment Securities shall be held subject to the same provisions hereof as the cash used to purchase the same, but upon a like request of the Company shall be sold, in whole or in designated part, and the proceeds of such sale shall be held subject to the same provisions hereof as the cash used to purchase the Investment Securities so sold. If such sale shall produce a net sum less than the cost of the Investment Securities so sold, the Company shall pay to the Trustee or any such Paying Agent, as the case may be, such amount in cash as, together with the net proceeds from such sale, shall equal the cost of the Investment Securities so sold, and if such sale shall produce a net sum greater than the cost of the Investment Securities so sold, the Trustee or any such Paying Agent, as the case may be, shall promptly pay over to the Company an amount in cash equal to such excess, free and clear of any Lien. In no event shall the Trustee be liable for any loss incurred in connection with the sale of any Investment Security pursuant to this Section.

Notwithstanding the foregoing, if an Event of Default shall have occurred and be continuing, interest on Investment Securities and any gain upon the sale thereof shall be held as part of the Mortgaged Property until such Event of Default shall have been cured or waived, whereupon such interest and gain shall be promptly paid over to the Company free and clear of any Lien.

32

under Article IV), any amounts denominated in a currency other than Dollars or in a composite currency shall be converted to Dollar equivalents by calculating the amount of Dollars which could have been purchased by the amount of such other currency based on such quotations or methods of determination as shall be specified pursuant to this clause (j);

(m) if the amount payable in respect of principal of or premium, if any, or interest, if any, on the Securities of such series, or any Tranche thereof, may be determined with reference to an index or other fact or event ascertainable outside of this Indenture, the manner in which such amounts shall be determined (to the extent not established pursuant to clause (e) of this paragraph); it being understood that all calculations under this Indenture (including calculations of principal amount under Article IV) shall be made on the basis of the amount that would be payable as principal if such principal were due, or on the basis of the interest rates in effect, as the case may be, on the date next preceding the date of such calculation;

Anything herein to the contrary notwithstanding, the Trustee shall be under no obligation to authenticate and deliver Securities of any series the terms of which, established as contemplated by this Section, would affect the rights, duties, obligations, liabilities or immunities of the Trustee under this Indenture or otherwise.

SECTION 3.02 Denominations.

Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, the Securities of each series shall be issuable in denominations of One Thousand Dollars ($1,000) and any integral multiple thereof.

34

SECTION 3.03 Execution, Dating, Certificate of Authentication.

Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, the Securities shall be executed on behalf of the Company by an Authorized Officer, and may have the corporate seal of the Company affixed thereto or reproduced thereon and attested by any other Authorized Officer. The signature of any or all of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at the time of execution Authorized Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

Unless otherwise specified as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, each Security shall be dated the date of its authentication.

Unless otherwise specified as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, no Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature of an authorized officer thereof, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if (a) any Security shall have been authenticated and delivered hereunder to the Company, or any Person acting on its behalf, but shall never have been issued and sold by the Company, (b) the Company shall deliver such Security to the Security Registrar for cancellation or shall cancel such Security and deliver evidence of such cancellation to the Trustee, in each case as provided in Section 3.09, and (c) the Company, at its election, shall deliver to the Trustee a written statement (which need not comply with Section 1.04 and need not be accompanied by an Officer's Certificate or an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, then, for all purposes of this Indenture, such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits hereof.

SECTION 3.04 Temporary Securities.

Pending the preparation of definitive Securities of any series, or any Tranche thereof, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed, photocopied or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities; provided, however, that temporary Securities need not recite specific redemption, sinking fund, conversion or exchange provisions.

35

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, after the preparation of definitive Securities of such series or Tranche, the temporary Securities of such series or Tranche shall be exchangeable, without charge to the Holder thereof, for definitive Securities of such series or Tranche upon surrender of such temporary Securities at the office or agency of the Company maintained pursuant to Section 6.02 in a Place of Payment for such Securities. Upon such surrender of temporary Securities, the Company shall, except as aforesaid, execute and the Trustee shall authenticate and deliver in exchange therefor definitive Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

Until exchanged in full as hereinabove provided, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and Tranche and of like tenor authenticated and delivered hereunder.

SECTION 3.05 Registration, Registration of Transfer and Exchange.

The Company shall cause to be kept in one of the offices designated pursuant to Section 6.02, with respect to the Securities of each series, or any Tranche thereof, a register (the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of such series or Tranche and the registration of transfer thereof. The Company shall designate one Person to maintain the Security Register for the Securities of each series, and such Person is referred to herein, with respect to such series, as the "Security Registrar". Anything herein to the contrary notwithstanding, the Company may designate one or more of its offices as an office in which a register with respect to the Securities of one or more series, or any Tranche or Tranches thereof, shall be maintained, and the Company may designate itself the Security Registrar with respect to one or more of such series. The Security Register shall be open for inspection by the Trustee and the Company at all reasonable times.

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, upon surrender for registration of transfer of any Security of such series or Tranche at the office or agency of the Company maintained pursuant to Section 6.02 in a Place of Payment for such series or Tranche, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, any Security of such series or Tranche may be exchanged at the option of the Holder, for one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

36

All Securities delivered upon any registration of transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee or the Security Registrar) be duly endorsed or shall be accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Security Registrar, as the case may be, duly executed by the Holder thereof or his attorney duly authorized in writing.

Unless otherwise specified as contemplated by Section 3.01 with respect to Securities of any series, or any Tranche thereof, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 5.06 or 14.06 not involving any transfer.

The Company shall not be required to execute or to provide for the registration of transfer of or the exchange of (a) Securities of any series, or any Tranche thereof, during a period of fifteen (15) days immediately preceding the date notice is to be given identifying the serial numbers of the Securities of such series or Tranche called for redemption or (b) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the ownership of and the destruction, loss or theft of any Security and (b) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security is held by a Person purporting to be the owner of such Security, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

Notwithstanding the foregoing, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, but subject to compliance with the foregoing conditions, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may

37

be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone other than the Holder of such new Security, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.07 Payment of Interest; Interest Rights Preserved.

Unless otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the related Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a date (herein called a "Special Record Date") for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than thirty (30) days and not less than ten (10) days prior to the date of the proposed payment and not less than twenty-five (25) days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall, not less than fifteen (15) days prior to such Special Record Date, cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest

38

shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date.

(b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and
Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.08 Persons Deemed Owners.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Sections 3.05 and 3.07) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.09 Cancellation by Security Registrar.

All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Security Registrar, be delivered to the Security Registrar and, if not theretofore canceled, shall be promptly canceled by the Security Registrar. The Company may at any time deliver to the Security Registrar for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever or which the Company shall not have issued and sold, and all Securities so delivered shall be promptly canceled by the Security Registrar. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.09, except as expressly permitted by this Indenture. All canceled Securities held by the Security Registrar shall be disposed of in accordance with the Security Registrar's then customary practice for disposing of securities, unless otherwise directed by a Company Order; provided, however, that the Trustee shall not be required to destroy any canceled Securities.

SECTION 3.10 Computation of Interest.

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, or any Tranche thereof, interest on the Securities of each series shall be computed on the basis of a three hundred sixty (360) day year consisting of twelve (12) thirty (30) day months and, with respect to any period less than a full calendar month, on the basis of the actual number of days elapsed during such period.

39

SECTION 3.11 Payment to Be in Proper Currency.

In the case of the Securities of any series, or any Tranche thereof, denominated in any currency other than Dollars or in a composite currency (the "Required Currency"), except as otherwise specified with respect to such Securities as contemplated by Section 3.01, the obligation of the Company to make any payment of the principal thereof, or the premium, if any, or interest, if any, thereon, shall not be discharged or satisfied by any tender by the Company, or recovery by the Trustee, in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and payable. If any such tender or recovery is in a currency other than the Required Currency, the Trustee may take such actions as it considers appropriate to exchange such currency for the Required Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of Required Currency then due and payable, and in no circumstances shall the Trustee be liable therefor except in the case of its negligence or willful misconduct.

SECTION 3.12 CUSIP Numbers.

The Company in issuing the Securities may use "CUSIP" or other similar numbers (if then generally in use), and, if so, the Trustee or Security Registrar may use "CUSIP" or such other numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, in which case none of the Company or, as the case may be, the Trustee or the Security Registrar, or any agent of any of them, shall have any liability in respect of any CUSIP number used on any such notice, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers.

Subject to the provisions of Section 4.02, 4.03 or 4.04, whichever may be applicable, the Trustee shall authenticate and deliver Securities of a series, for original issue, at one time or from time to time in accordance with the Company Order referred to below, upon receipt by the Trustee of:

(iii) when such Securities shall have been authenticated and delivered by the Trustee and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, such Securities will constitute valid obligations of the Company, entitled to the benefit of the Lien of this Indenture equally and ratably with all other Securities then Outstanding;

provided, however, that, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive such Opinion of Counsel only once at or prior to the time of the first authentication and delivery of such Securities (provided that such Opinion of Counsel addresses the authentication and delivery of all such Securities) and that, in lieu of the opinions described in clauses (ii) and (iii) above, counsel may opine that:

ARTICLE V

REDEMPTION OF SECURITIES

SECTION 5.01 Applicability of Article.

Securities of any series, or any Tranche thereof, which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for Securities of such series or Tranche) in accordance with this Article.

SECTION 5.02 Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or an Officer's Certificate. The Company shall, at least forty-five (45) days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory

46

to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of such Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officer's Certificate evidencing compliance with such restriction or condition.

SECTION 5.03 Selection of Securities to Be Redeemed.

If less than all the Securities of any series, or any Tranche thereof, are to be redeemed, the particular Securities to be redeemed shall be selected by the Security Registrar from the Outstanding Securities of such series or Tranche not previously called for redemption, by such method as shall be provided for any particular series or Tranche, or, in the absence of any such provision, by such method of random selection as the Security Registrar shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of such series or Tranche or any integral multiple thereof) of the principal amount of Securities of such series or Tranche having a denomination larger than the minimum authorized denomination for Securities of such series or Tranche; provided, however, that if, as indicated in an Officer's Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and less than all of such Securities as to which such offer was made shall have been tendered to the Company for such purchase, the Security Registrar, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered.

The Security Registrar shall promptly notify the Company and the Trustee in writing of the Securities selected for redemption and, in the case of any Securities selected to be redeemed in part, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

SECTION 5.04 Notice of Redemption.

Notice of redemption shall be given in the manner provided in
Section 1.08 to the Holders of the Securities to be redeemed not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date.

All notices of redemption shall state:

(a) the Redemption Date,

(b) the Redemption Price,

47

(c) if less than all the Securities of any series or Tranche are to be redeemed, the identification of the particular Securities to be redeemed and the portion of the principal amount of any Security to be redeemed in part,

(d) that on the Redemption Date the Redemption Price, together with accrued interest, if any, to the Redemption Date, will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(e) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any, unless it shall have been specified as contemplated by Section 3.01 with respect to such Securities that such surrender shall not be required,

(f) that the redemption is for a sinking or other fund, if such is the case, and

(g) such other matters as the Company shall deem desirable or appropriate.

With respect to any notice of redemption of Securities at the election of the Company, unless, upon the giving of such notice, such Securities shall be deemed to have been paid in accordance with Section 9.01, such notice may state that such redemption shall be conditional upon the receipt by the Paying Agent or Agents for such Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made, and the Paying Agent or Agents for the Securities otherwise to have been redeemed shall promptly return to the Holders thereof any of such Securities which had been surrendered for payment upon such redemption.

Notice of redemption of Securities to be redeemed at the election of the Company, and any notice of non-satisfaction of a condition for redemption as aforesaid, shall be given by the Company or, at the Company's request, by the Security Registrar in the name and at the expense of the Company. Notice of mandatory redemption of Securities shall be given by the Security Registrar in the name and at the expense of the Company.

SECTION 5.05 Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities or portions thereof so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless, in the case of an unconditional notice of redemption, the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security or portion thereof shall be paid by the Company at the Redemption Price, together with

48

accrued interest, if any, to the Redemption Date; provided, however, that no such surrender shall be a condition to such payment if so specified as contemplated by Section 3.01 with respect to such Security; and provided, further, that, except as otherwise specified as contemplated by Section 3.01 with respect to such Security, any installment of interest on any Security the Stated Maturity of which installment is on or prior to the Redemption Date shall be payable to the Holder of such Security, or one or more Predecessor Securities, registered as such at the close of business on the related Regular Record Date according to the terms of such Security and subject to the provisions of Section 3.07.

SECTION 5.06 Securities Redeemed in Part.

Upon the surrender of any Security which is to be redeemed only in part at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities of the same series and Tranche, of any authorized denomination requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency and prompt notice to the Holders of any such change in the manner specified in Section 1.08. If at any time the Company

The Company may also from time to time designate one or more other offices or agencies with respect to the Securities of one or more series, or any Tranche thereof, for any or all of the foregoing purposes and may from time to time rescind such designations; provided, however, that, unless otherwise specified as contemplated by Section 3.01 with respect to the Securities of such series or Tranche, no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes in each Place of Payment for such Securities in accordance with the requirements set forth above. The Company shall give prompt written notice to the Trustee, and prompt notice to the Holders in the manner specified in Section 1.08, of any such designation or rescission and of any change in the location of any such other office or agency.

Anything herein to the contrary notwithstanding, any office or agency required by this Section may be maintained at an office of the Company, in which event the Company shall perform all functions to be performed at such office or agency.

SECTION 6.03 Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on any of such Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company shall promptly notify the Trustee of any failure by the Company (or any other obligor on such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities.

Whenever the Company shall have one or more Paying Agents for the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on such Securities, deposit with such Paying Agents sums sufficient (without duplication) to pay the principal and premium or interest so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of any failure by it so to act.

The Company shall cause each Paying Agent for the Securities of any series, or any Tranche thereof, other than the Company or the Trustee, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

(b) give the Trustee notice of any failure by the Company (or any other obligor upon such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities; and

(c) at any time during the continuance of any such failure, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent and furnish to the Trustee such information as it possesses regarding the names and addresses of the Persons entitled to such sums.

The Company may at any time pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a Company Order delivered to the Trustee, in accordance with the provisions of Article IX; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on Company Request, or, if then held by the Company, shall be discharged from such trust; and, upon such payment or discharge, the Holder of such Security shall, as an unsecured general creditor and not as the Holder of an Outstanding Security, look only to the Company for payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment to the Company, shall, upon receipt of a Company Request and at the expense of the Company, cause to be mailed, on one occasion only, notice to such Holder that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such mailing, any unclaimed balance of such money then remaining will be paid to the Company.

51

to property owned in common with others, make reasonable effort to cause) to be made such repairs, renewals, replacements, betterments and improvements thereof, as, in the judgment of the Company, may be necessary in order that the operation of the Mortgaged Property, considered as a whole, may be conducted in accordance with common industry practice; provided, however, that nothing in this Section shall prevent the Company from discontinuing, or causing the discontinuance of, the operation and maintenance of any portion of the Mortgaged Property; and provided, further, that nothing in this Section shall prevent the Company from selling, transferring or otherwise disposing of, or causing the sale, transfer or other disposition of, any portion of the Mortgaged Property.

SECTION 6.06 Payment of Taxes; Discharge of Liens.

The Company shall pay all taxes and assessments and other governmental charges lawfully levied or assessed upon the Mortgaged Property, or upon any part thereof, or upon the interest of the Trustee in the Mortgaged Property, before the same shall become delinquent, and shall make reasonable effort to observe and conform in all material respects to all valid requirements of any Governmental Authority relative to any of the Mortgaged Property and all covenants, terms and conditions upon or under which any of the Mortgaged Property is held; and the Company shall not suffer any Lien to be created upon the Mortgaged Property, or any part thereof, prior to the Lien hereof, other than Permitted Liens and other than, in the case of property hereafter acquired, Purchase Money Liens and any other Liens existing or placed thereon at the time of the acquisition thereof; provided, however, that nothing in this Section contained shall require the Company (i) to observe or conform to any requirement of Governmental Authority or to cause to be paid or discharged, or to make provision for, any such Lien, or to pay any such tax, assessment or governmental charge so long as the validity thereof shall be contested in good faith and by appropriate legal proceedings, (ii) to pay, discharge or make provisions for any tax, assessment or other governmental charge, the validity of which shall not be so contested if adequate security for the payment of such tax, assessment or other governmental charge and for any penalties or interest which may reasonably be anticipated from failure to pay the same shall be given to the Trustee or
(iii) to pay, discharge or make provisions for any Liens existing on the Mortgaged Property at the date of execution and delivery of this Indenture, as originally executed and delivered; and provided, further, that nothing in this
Section shall prohibit the issuance or other incurrence of additional indebtedness, or the refunding of outstanding indebtedness, secured by any Lien prior to the Lien hereof which is permitted under this Section to continue to exist.

SECTION 6.07 Insurance.

(a) The Company shall (i) keep or cause to be kept all the property subject to the Lien of this Indenture insured against loss by fire, to the extent that property of similar character is usually so insured by companies similarly situated and operating like properties, to a reasonable amount, by reputable insurance companies, the proceeds of such insurance (except as to any loss of Excepted Property and except as to any particular loss less than the greater of (A) Ten Million Dollars ($10,000,000) and (B) three percentum (3%) of the sum of (1) the principal amount of Securities Outstanding on the date of such particular loss and (2) the principal amount of the First Mortgage Bonds Outstanding on the date of such particular loss) to be made payable, subject to applicable law, to the Trustee as the interest of the Trustee may

52

appear, to the trustee of the NVP 1953 Mortgage, or to the trustee or other holder of any other Lien prior hereto upon property subject to the Lien hereof, if the terms thereof require such payment or (ii) in lieu of or supplementing such insurance in whole or in part, adopt some other method or plan of protection against loss by fire at least equal in protection to the method or plan of protection against loss by fire of companies similarly situated and operating properties subject to similar fire hazards or properties on which an equal primary fire insurance rate has been set by reputable insurance companies; and if the Company shall adopt such other method or plan of protection, it shall, subject to applicable law (and except as to any loss of Excepted Property and except as to any particular loss less than the greater of (X) Ten Million Dollars ($10,000,000) and (Y) three percentum (3%) of the sum of (1) the principal amount of Securities Outstanding on the date of such particular loss and (2) the principal amount of the First Mortgage Bonds Outstanding on the date of such particular loss) pay to the Trustee on account of any loss covered by such method or plan an amount in cash equal to the amount of such loss less any amounts otherwise paid to the Trustee in respect of such loss or paid to the trustee under the NVP 1953 Mortgage or to the trustee or other holder of any other Lien prior hereto upon property subject to the Lien hereof in respect of such loss if the terms thereof require such payment. Any cash so required to be paid by the Company pursuant to any such method or plan shall for the purposes of this Indenture be deemed to be proceeds of insurance. In case of the adoption of such other method or plan of protection, the Company shall also furnish to the Trustee a certificate of an actuary or other qualified person appointed by the Company with respect to the adequacy of such method or plan.

Anything herein to the contrary notwithstanding, the Company may have fire insurance policies with (i) a deductible provision in a dollar amount per occurrence not exceeding the greater of (A) Ten Million Dollars ($10,000,000) and (B) three percentum (3%) of the sum of (1) the principal amount of the Securities Outstanding on the date such policy goes into effect and (2) the principal amount of the First Mortgage Bonds Outstanding on the date such policy goes into effect, and/or (ii) co-insurance or self insurance provisions with a dollar amount per occurrence not exceeding thirty percentum (30%) of the loss proceeds otherwise payable; provided, however, that the dollar amount described in clause (i) above may be exceeded to the extent such dollar amount per occurrence is below the deductible amount in effect as to fire insurance (X) on property of similar character insured by companies similarly situated and operating like property or (Y) on property as to which an equal primary fire insurance rate has been set by reputable insurance companies.

(b) All moneys paid to the Trustee by the Company in accordance with this Section or received by the Trustee as proceeds of any insurance, in either case on account of a loss on or with respect to Funded Property, shall, subject to the requirements of the NVP 1953 Mortgage or other Lien prior hereto upon property subject to the Lien hereof, be held by the Trustee and, subject as aforesaid, shall be paid by it to the Company to reimburse the Company for an equal amount expended or committed for expenditure in the rebuilding, renewal and/or replacement of or substitution for the property destroyed or damaged or lost, upon receipt by the Trustee of:

61

and/or the filing and/or recording in the proper places and manner of, the instruments of conveyance, assignment or transfer, if any, specified in such opinion, will constitute, a Lien upon all other property, if any, purporting to be subject thereto, subject to no Lien prior thereto except Liens generally of the character of Permitted Liens and Liens permitted to exist or to be hereafter created under
Section 6.06 and (B) that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder except on the basis of property generally of the character of Property Additions, the retirement or deposit of outstanding obligations, the deposit of prior Lien obligations or the deposit of cash.

Anything herein to the contrary notwithstanding (a) the aggregate principal amount of obligations secured by Purchase Money Lien which may be used pursuant to subclause (i) and/or subclause (iv) of clause (d) in the first paragraph of this Section as the basis for the release of property from the Lien of this Indenture shall not exceed seventy-five percentum (75%) of the Fair Value of the property to be released, as certified pursuant to clause

(x) an Officer's Certificate (i) if any obligations shall then be outstanding under such Purchase Money Lien and/or additional obligations are permitted to be issued thereunder, either (A) stating that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder on the basis of property additions in a principal amount exceeding seventy percentum (70%) of the balance of the cost or fair value of such property additions to the issuer thereof (whichever shall be less) after making deductions and additions similar to those provided for in Section 1.03, or (B) in the event that the statements contained in clause (A) above cannot be made, stating that such issuer has irrevocably waived its right to the authentication and delivery of obligations under such Purchase Money Lien (1) on any basis, in a principal amount equal to the excess of (I) the aggregate principal amount of obligations, if any, then outstanding under such Purchase Money Lien which were issued on the basis of property additions or on the basis of the retirement of obligations which were issued (whether directly or indirectly when considered in light of the successive issuance and retirement of obligations) on the basis of property additions over (II) an amount equal to seventy percentum (70%) of the aggregate Dollar amount of property

(y) an Opinion or Opinions of Counsel to the effect that (i) if any obligations shall then be outstanding under such Purchase Money Lien and/or additional obligations are permitted to be issued thereunder, to the effect either (A) that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder upon the basis of property additions in a principal amount exceeding seventy percentum (70%) of the balance of the cost or the fair value thereof to the issuer of such obligations (whichever shall be less) after making deductions and additions similar to those provided for in Section 1.03, or, if such is not the case, (B) that the waivers contemplated by clause (x)(i)(B) above have been duly made and (ii) to the effect either (A) that the obligations secured by such Purchase Money Lien delivered to the Trustee or to the trustee or other holder of a Lien prior to the Lien of this Indenture as the basis for such release of property contain a provision for mandatory redemption upon an acceleration) of the maturity of all Outstanding Securities following an Event of Default (whether or not such redemption may be rescinded upon the rescission of such acceleration) or (B) that, so long as such obligations are held by the Trustee or the trustee or other holder of such a prior Lien, an Event of Default under this Indenture constitutes a matured event of default under such Purchase Money Lien (provided, however, that the waiver or cure of such Event of Default hereunder and the rescission and annulment of the consequences thereof may constitute a cure of the corresponding event of default under such Purchase Money Lien and a rescission and annulment of the consequences thereof).

If (a) any property to be released from the Lien of this Indenture under any provision of this Article (other than Section 8.07) is subject to a Lien prior to the Lien hereof and is to be sold, exchanged, dedicated or otherwise disposed of subject to such prior Lien and (b) after such release, such prior Lien will not be a Lien on any property subject to the Lien hereof, then the Fair Value of such property to be released shall be deemed, for all purposes of this Indenture, to be the value thereof unencumbered by such prior Lien less the principal amount of the indebtedness secured by such prior Lien.

63

Any Outstanding Securities delivered to the Trustee pursuant to clause (d) in the first paragraph of this Section shall forthwith be canceled by the Trustee. Any cash and/or obligations so deposited with the Trustee, and the proceeds of any such obligations, shall be held as part of the Mortgaged Property and shall be withdrawn, released, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

Notwithstanding the provisions of Sections 8.03 and 8.04, unless an Event of Default shall have occurred and be continuing, the Company may obtain the release from the Lien hereof of any part of the Mortgaged Property, or any interest therein, and the Trustee shall whenever from time to time requested by the Company in a Company Order transmitting therewith a form of instrument to effect such release, and without requiring compliance with any of the provisions of Section 8.03 or 8.04, release from the Lien hereof all the right, title and interest of the Trustee in and to the same provided that the aggregate Fair Value of the property to be so released on any date in a given calendar year, together with all other property released pursuant to this
Section 8.05 in such calendar year, shall not exceed the greater of (a) Ten Million Dollars ($10,000,000) and (b) three percentum (3%) of the sum of (i) the aggregate principal amount of Securities then Outstanding and (ii) the aggregate principal amount of First Mortgage Bonds then Outstanding. Prior to the granting of any such release, there shall be

65

delivered to the Trustee (x) an Officer's Certificate stating that, to the knowledge of the signer, no Event of Default has occurred and is continuing and
(y) an Expert's Certificate stating, in the judgment of the signers, the Fair Value of the property to be released, the aggregate Fair Value of all other property theretofore released pursuant to this Section in such calendar year and, as to Funded Property, the Cost thereof (or, if the Fair Value to the Company of such property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost), and that, in the judgment of the signers, the release thereof will not impair the security under this Indenture in contravention of the provisions hereof. On or before December 31st of each calendar year, the Company shall deposit with the Trustee an amount in cash equal to seventy percentum (70%) of the aggregate Cost of the properties constituting Funded Property so released during such year (or, if the Fair Value to the Company of any particular property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost); provided, however, that no such deposit shall be required to be made hereunder to the extent that cash or other consideration shall, as indicated in an Officer's Certificate delivered to the Trustee, have been deposited with the trustee or other holder of the NVP 1953 Mortgage or other Lien prior to the Lien of this Indenture in accordance with the provisions thereof; and provided, further, that the amount of cash so required to be deposited may be reduced, at the election of the Company, by the items specified in clause (d) in the first paragraph of Section 8.03, subject to all of the limitations and conditions specified in such Section, to the same extent as if such property were being released pursuant to Section 8.03. Any cash deposited with the Trustee under this Section may thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

SECTION 8.06 Withdrawal or Other Application of Funded Cash; Purchase Money Obligations.

Subject to the provisions of Section 4.04 and except as hereafter in this Section provided, unless an Event of Default shall have occurred and be continuing, any Funded Cash held by the Trustee, and any other cash which is required to be withdrawn, used or applied as provided in this Section,

(a) may be withdrawn from time to time by the Company to the extent of an amount equal to seventy percentum (70%) of the Cost or the Fair Value to the Company (whichever is less) of Property Additions not constituting Funded Property, after making any deductions and additions pursuant to Section 1.03, described in an Expert's Certificate, dated not more than ninety (90) days prior to the date of the Company Order requesting such withdrawal and complying with clause (ii) and, to the extent applicable, clause (iii) in Section 4.02(b), delivered to the Trustee; provided, however, that the deductions and additions contemplated by Section 1.03 shall not be required to be made if such Property Additions were acquired, made or constructed on or after the ninetieth (90th) day preceding the date of such Company Order;

(b) may be withdrawn from time to time by the Company in an amount equal to the aggregate principal amount of Securities to the authentication and delivery of which the Company shall be entitled under the provisions of Section 4.03 hereof, by virtue of compliance with all applicable provisions of Section 4.03 (except as hereinafter in this Section otherwise provided); provided, however, that such withdrawal of cash shall operate as a waiver by the

66

Company of the right to the authentication and delivery of such Securities and, to such extent, no such Securities may thereafter be authenticated and delivered hereunder; and any such Securities which were the basis of such right to the authentication and delivery of Securities so waived shall be deemed to have been made the basis of such withdrawal of cash;

(c) may be withdrawn from time to time by the Company in an amount equal to the aggregate principal amount of any Outstanding Securities delivered to the Trustee;

(d) may, upon the request of the Company, be used by the Trustee for the purchase of Securities in the manner, at the time or times, in the amount or amounts, at the price or prices and otherwise as directed or approved by the Company, all subject to the limitations hereafter in this
Section set forth; or

(e) may, upon the request of the Company, be applied by the Trustee to the payment (or provision therefor pursuant to Article IX) at Stated Maturity of any Securities or to the redemption (or similar provision therefor) of any Securities which are, by their terms, redeemable, in each case of such series as may be designated by the Company, any such redemption to be in the manner and as provided in Article V, all subject to the limitations hereafter in this Section set forth.

Such moneys shall, from time to time, be paid or used or applied by the Trustee, as aforesaid, upon the request of the Company in a Company Order, and upon receipt by the Trustee of an Officer's Certificate stating that, to the knowledge of the signer, no Event of Default has occurred and is continuing. If and to the extent that the withdrawal of cash is based upon Property Additions (as permitted under the provisions of clause (a) above), the Company shall, subject to the provisions of said clause (a) and except as hereafter in this paragraph provided, comply with all applicable provisions of this Indenture as if such Property Additions were made the basis for the authentication and delivery of Securities equal in principal amount to the cash so to be withdrawn. If and to the extent that the withdrawal of cash is based upon the right to the authentication and delivery of Securities (as permitted under the provisions of clause (b) above), the Company shall, except as hereafter in this paragraph provided, comply with all applicable provisions of
Section 4.03 relating to such authentication and delivery. Notwithstanding the foregoing provisions of this paragraph, in no event shall the Company be required to deliver the documents specified in Section 4.01.

Notwithstanding the generality of clauses (d) and (e) above, no cash to be applied pursuant to such clauses shall be applied to the payment of an amount in excess of the principal amount of any Securities to be purchased, paid or redeemed except to the extent that the aggregate principal amount of all Securities theretofore, and of all Securities then to be, purchased, paid or redeemed pursuant to such clauses is not less than the aggregate cost for principal of, premium, if any, and accrued interest, if any, on and brokerage commissions, if any, with respect to, such Securities.

Any Outstanding Securities delivered to the Trustee pursuant to clause (c) in the first paragraph of this Section shall forthwith be canceled by the Trustee.

67

Any obligations secured by Purchase Money Lien delivered to the Trustee in consideration of the release of property from the Lien of this Indenture, together with any evidence of such Purchase Money Lien held by the Trustee, shall be released from the Lien of this Indenture and delivered to or upon the order of the Company upon payment by the Company to the Trustee of an amount in cash equal to the aggregate principal amount of such obligations less the aggregate amount theretofore paid to the Trustee (by the Company, the obligor or otherwise) in respect of the principal of such obligations.

The principal of and interest on any such obligations secured by Purchase Money Lien held by the Trustee shall be held by the Trustee as and when the same are received by the Trustee. The interest received by the Trustee on any such obligations shall be deemed not to constitute Funded Cash and shall be remitted to the Company; provided, however, that if an Event of Default shall have occurred and be continuing, such proceeds shall be held as part of the Mortgaged Property until such Event of Default shall have been cured or waived.

The Trustee shall have and may exercise all the rights and powers of any owner of such obligations and of all substitutions therefor and, without limiting the generality of the foregoing, may collect and receive all insurance moneys payable to it under any of the provisions thereof and apply the same in accordance with the provisions thereof, may consent to extensions thereof at a higher or lower rate of interest, may join in any plan or plans of voluntary or involuntary reorganization or readjustment or rearrangement and may accept and hold hereunder new obligations, stocks or other securities issued in exchange therefor under any such plan. Any discretionary action which the Trustee may be entitled to take in connection with any such obligations or substitutions therefor shall be taken, so long as no Event of Default shall have occurred and be continuing, in accordance with a Company Order, and, during the continuance of an Event of Default, in its own discretion.

Anything herein to the contrary notwithstanding, the Company may irrevocably waive all right to the withdrawal pursuant to this Section of, and any other rights with respect to, any obligations secured by Purchase Money Lien held by the Trustee, and the proceeds of any such obligations, by delivery to the Trustee of a Company Order:

(a) specifying such obligations and stating that the Company thereby waives all rights to the withdrawal thereof and of the proceeds thereof pursuant to this Section, and any other rights with respect thereto; and

(b) directing that the principal of such obligations be applied as provided in clause (e) in the first paragraph of this Section, specifying the Securities to be paid or redeemed or for the payment or redemption of which payment is to be made.

Following any such waiver, the interest on any such obligations shall be applied to the payment of interest, if any, on the Securities to be paid or redeemed or for the payment or redemption of which provision is to be made, as specified in the aforesaid Company Order, as and when such interest shall become due from time to time, and any excess funds remaining from time to time after such application shall be applied to the payment of interest on any other Securities as and when the same shall become due. Pending any such application, the interest on such obligations shall be invested in Investment Securities. The principal of any such obligations shall be applied

68

solely to the payment of principal of the Securities to be paid or redeemed or for the payment or redemption of which provision is to be made, as specified in the aforesaid Company Order. Pending such application, the principal of such obligations shall be invested in Eligible Obligations. The obligation of the Company to pay the principal of such Securities when the same shall become due at maturity, shall be offset and reduced by the amount of the proceeds of such obligations then held, and to be applied, by the Trustee in accordance with this paragraph.

SECTION 8.07 Release of Property Taken by Eminent Domain, etc.

Should any of the Mortgaged Property, or any interest therein, be taken by exercise of the power of eminent domain or be sold to an entity possessing the power of eminent domain under a threat to exercise the same, and should the Company elect not to obtain the release of such property pursuant to other provisions of this Article, the Trustee shall, upon request of the Company evidenced by a Company Order transmitting therewith a form of instrument to effect such release, release from the Lien hereof all its right, title and interest in and to the property so taken or sold (or with respect to an interest in property, subordinate the Lien hereof to such interest), upon receiving (a) an Opinion of Counsel to the effect that such property has been taken by exercise of the power of eminent domain or has been sold to an entity possessing the power of eminent domain under threat of an exercise of such power, (b) an Officer's Certificate stating the amount of net proceeds received or to be received for such property so taken or sold, and the amount so stated shall be deemed to be the Fair Value of such property for the purpose of any notice to the Holders of Securities, (c) if any portion of such property constitutes Funded Property, an Expert's Certificate stating the Cost thereof (or, if the Fair Value to the Company of such portion of such property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost) and (d) if any portion of such property constitutes Funded Property, a deposit by the Company of an amount in cash equal to seventy percentum (70%) of the Cost or Fair Value stated in the Expert's Certificate delivered pursuant to clause (c) above; provided, however, that the amount required to be so deposited shall not exceed the portion of the net proceeds received or to be received for such property so taken or sold which is allocable on a pro-rata or other reasonable basis to the portion of such property constituting Funded Property; and provided, further, that no such deposit shall be required to be made hereunder if the proceeds of such taking or sale shall, as indicated in an Officer's Certificate delivered to the Trustee, have been deposited with the trustee or other holder of the NVP 1953 Mortgage or other Lien prior to the Lien of this Indenture. Any cash deposited with the Trustee under this Section may thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

SECTION 8.08 Disclaimer or Quitclaim.

In case the Company has sold, exchanged, dedicated or otherwise disposed of, or has agreed or intends to sell, exchange, dedicate or otherwise dispose of, or a Governmental Authority has ordered the Company to divest itself of, any Excepted Property or any other property not subject to the Lien hereof, or the Company desires to disclaim or quitclaim title to property to which the Company does not purport to have title, the Trustee shall, from time to time, disclaim or quitclaim such property upon receipt by the Trustee of the following:

69

(a) a Company Order requesting such disclaimer or quitclaim and transmitting therewith a form of instrument to effect such disclaimer or quitclaim;

(b) an Officer's Certificate describing the property to be disclaimed or quitclaimed; and

(c) an Opinion of Counsel stating the signer's opinion that such property is not subject to the Lien hereof or required to be subject thereto by any of the provisions hereof.

SECTION 8.09 Miscellaneous.

(a) The Expert's Certificate as to the Fair Value of property to be released from the Lien of this Indenture in accordance with any provision of this Article, and as to the nonimpairment, by reason of such release, of the security under this Indenture in contravention of the provisions hereof, shall be made by an Independent Expert if the Fair Value of such property and of all other property released since the commencement of the then current calendar year, as set forth in the certificates required by this Indenture, is ten percentum (10%) or more of the aggregate principal amount of the Securities at the time Outstanding; but such Expert's Certificate shall not be required to be made by an Independent Expert in the case of any release of property if the Fair Value thereof, as set forth in the certificates required by this Indenture, is less than Twenty-five Thousand Dollars ($25,000) or less than one percentum (1%) of the aggregate principal amount of the Securities at the time Outstanding. To the extent that the Fair Value of any property to be released from the Lien of this Indenture shall be stated in an Independent Expert's Certificate, such Fair Value shall not be required to be stated in any other Expert's Certificate delivered in connection with such release.

(b) No release of property from the Lien of this Indenture effected in accordance with the provisions, and in compliance with the conditions, set forth in this Article and in Sections 1.04 and 1.05 shall be deemed to impair the security of this Indenture in contravention of any provision hereof.

(d) If the Company shall retain any interest in any property released from the Lien of this Indenture as provided in Section 8.03, 8.04 or 8.05, this Indenture shall not become or be, or be required to become or be, a Lien upon such property or such interest therein or any improvements, extensions or additions to such property or renewals, replacements or substitutions of or for such property or any part or parts thereof unless the Company shall

70

execute and deliver to the Trustee an indenture supplemental hereto, in recordable form, containing a grant, conveyance, transfer and mortgage thereof. As used in this subsection, the terms "improvements", "extensions" and "additions" shall be limited as set forth in Section 13.01.

(e) Notwithstanding the occurrence and continuance of an Event of Default, the Trustee, in its discretion, may release from the Lien hereof any part of the Mortgaged Property or permit the withdrawal of cash, upon compliance with the other conditions specified in this Article in respect thereof.

(f) No purchaser or grantee of property purporting to have been released hereunder shall be bound to ascertain the authority of the Trustee to execute the release, or to inquire as to any facts required by the provisions hereof for the exercise of such authority; nor shall any purchaser or grantee of any property or rights permitted by this Article to be sold, granted, exchanged, dedicated or otherwise disposed of, be under obligation to ascertain or inquire into the authority of the Company to make any such sale, grant, exchange, dedication or other disposition.

ARTICLE IX

SATISFACTION AND DISCHARGE

SECTION 9.01 Satisfaction and Discharge of Securities.

Any Security or Securities, or any portion of the principal amount thereof, shall be deemed to have been paid for all purposes of this Indenture, and the entire indebtedness of the Company in respect thereof shall be satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust:

(a) money (including Funded Cash not otherwise applied pursuant to Section 8.06) in an amount which shall be sufficient, or

(b) in the case of a deposit made prior to the Maturity of such Securities or portions thereof, Eligible Obligations, which shall not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee or such Paying Agent, shall be sufficient, or

(c) a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof; provided, however, that in the case of the provision for payment or redemption of less than all the Securities of any series or Tranche, such Securities or portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such redemption shall have been given or irrevocable authority shall have been given by the Company to the Trustee to give such

71

notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the Trustee and such Paying Agent:

(x) if such deposit shall have been made prior to the Maturity of such Securities, a Company Order stating that the money and Eligible Obligations deposited in accordance with this Section shall be held in trust, as provided in Section 9.03;

(y) if Eligible Obligations shall have been deposited, an Opinion of Counsel to the effect that such obligations constitute Eligible Obligations and do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, and an opinion of an Independent public Accountant of nationally recognized standing, selected by the Company, to the effect that the other requirements set forth in clause (b) above have been satisfied; and

(z) if such deposit shall have been made prior to the Maturity of such Securities, an Officer's Certificate stating the Company's intention that, upon delivery of such Officer's Certificate, its indebtedness in respect of such Securities or portions thereof will have been satisfied and discharged as contemplated in this Section.

Upon the deposit of money or Eligible Obligations, or both, in accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon Company Request, acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof has been satisfied and discharged as contemplated in this Section. In the event that all of the conditions set forth in the preceding paragraph shall have been satisfied in respect of any Securities or portions thereof except that, for any reason, the Officer's Certificate specified in clause (z) (if otherwise required) shall not have been delivered, such Securities or portions thereof shall nevertheless be deemed to have been paid for all purposes of this Indenture, and the Holders of such Securities or portions thereof shall nevertheless be no longer entitled to the benefit of the Lien of this Indenture or of any of the covenants of the Company under Article VI (except the covenants contained in Sections 6.02 and 6.03) or any other covenants made in respect of such Securities or portions thereof as contemplated by Section 3.01, but the indebtedness of the Company in respect of such Securities or portions thereof shall not be deemed to have been satisfied and discharged prior to Maturity for any other purpose; and, upon Company Request, the Trustee shall acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture.

If payment at Stated Maturity of less than all of the Securities of any series, or any Tranche thereof, is to be provided for in the manner and with the effect provided in this Section, the Security Registrar shall select such Securities, or portions of principal amount thereof, in the manner specified by Section 5.03 for selection for redemption of less than all the Securities of a series or Tranche.

In the event that Securities which shall be deemed to have been paid for purposes of this Indenture, and, if such is the case, in respect of which the Company's indebtedness shall have been satisfied and discharged, all as provided in this Section, do not mature and are not to

72

be redeemed within the sixty (60) day period commencing with the date of the deposit of moneys or Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a notice, in the same manner as a notice of redemption with respect to such Securities, to the Holders of such Securities to the effect that such deposit has been made and the effect thereof.

Notwithstanding that any Securities shall be deemed to have been paid for purposes of this Indenture, as aforesaid, the obligations of the Company and the Trustee in respect of such Securities under Sections 3.04, 3.05, 3.06, 5.04, 6.02, 6.03, 11.07 and 11.15 and this Article shall survive.

The Company shall pay, and shall indemnify the Trustee or any Paying Agent with which Eligible Obligations shall have been deposited as provided in this Section against, any tax, fee or other charge imposed on or assessed against such Eligible Obligations or the principal or interest received in respect of such Eligible Obligations, including, but not limited to, any such tax payable by any entity deemed, for tax purposes, to have been created as a result of such deposit.

Anything herein to the contrary notwithstanding, (a) if, at any time after a Security would be deemed to have been paid for purposes of this Indenture, and, if such is the case, the Company's indebtedness in respect thereof would be deemed to have been satisfied and discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or any Paying Agent, as the case may be, shall be required to return the money or Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable Federal or State bankruptcy, insolvency or other similar law, such Security shall thereupon be deemed retroactively not to have been paid and any satisfaction and discharge of the Company's indebtedness in respect thereof shall retroactively be deemed not to have been effected, and such Security shall be deemed to remain Outstanding and (b) any satisfaction and discharge of the Company's indebtedness in respect of any Security shall be subject to the provisions of the last paragraph of
Section 6.03.

SECTION 9.02 Satisfaction and Discharge of Indenture.

This Indenture shall upon Company Request cease to be of further effect (except as hereinafter expressly provided), and the Trustee, at the expense of the Company, shall execute such instruments as the Company shall reasonably request to evidence and acknowledge the satisfaction and discharge of this Indenture, when:

(a) no Securities remain Outstanding hereunder; and

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company;

provided, however, that if, in accordance with the last paragraph of Section 9.01, any Security, previously deemed to have been paid for purposes of this Indenture, shall be deemed retroactively not to have been so paid, this Indenture shall thereupon be deemed retroactively not to have been satisfied and discharged, as aforesaid, and to remain in full force and effect, and the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same.

73

Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the Trustee under Sections 3.04, 3.05, 3.06, 5.04, 6.02, 6.03, 11.07 and 11.15 and this Article shall survive.

Upon satisfaction and discharge of this Indenture as provided in this Section, the Trustee shall release, quit claim and otherwise turn over to the Company the Mortgaged Property (other than money and Eligible Obligations held by the Trustee pursuant to Section 9.03) and shall execute and deliver to the Company such deeds and other instruments as, in the judgment of the Company, shall be necessary, desirable or appropriate to effect or evidence such release and quitclaim and the satisfaction and discharge of this Indenture.

SECTION 9.03 Application of Trust Money.

Neither the Eligible Obligations nor the money deposited pursuant to Section 9.01, nor the principal or interest payments on any such Eligible Obligations, shall be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Securities or portions of principal amount thereof in respect of which such deposit was made, all subject, however, to the provisions of Section 6.03; provided, however, that any cash received from such principal or interest payments on such Eligible Obligations, if not then needed for such purpose, shall, to the extent practicable and upon Company Request and delivery to the Trustee of the documents referred to in clause (y) in the first paragraph of Section 9.01, be invested in Eligible Obligations of the type described in clause (b) in the first paragraph of Section 9.01 maturing at such times and in such amounts as shall be sufficient, together with any other moneys and the proceeds of any other Eligible Obligations then held by the Trustee, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on and prior to the Maturity thereof, and interest earned from such reinvestment shall be paid over to the Company as received, free and clear of the Lien of this Indenture, except the Lien provided by Section 11.07; and provided, further, that any moneys held in accordance with this Section on the Maturity of all such Securities in excess of the amount required to pay the principal of and premium, if any, and interest, if any, then due on such Securities shall be paid over to the Company free and clear of the Lien of this Indenture, except the Lien provided by
Section 11.07; and provided, further, that if an Event of Default shall have occurred and be continuing, moneys to be paid over to the Company pursuant to this Section shall be held as part of the Mortgaged Property until such Event of Default shall have been waived or cured.

ARTICLE X

(d) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding up or liquidation of its affairs, and any such decree or order for relief or any such other decree or order shall have remained unstayed and in effect for a period of ninety (90) consecutive days; or

75

that, anything in this Indenture to the contrary notwithstanding, the waiver or cure of such event of default under the NVP 1953 Mortgage and the rescission and annulment of the consequences thereof under the NVP 1953 Mortgage shall constitute a cure of the corresponding Event of Default hereunder and a rescission and annulment of the consequences thereof.

SECTION 10.02 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default shall have occurred and be continuing, then in every such case the Trustee or the Holders of not less than thirty-three percentum (33%) in principal amount of the Securities then Outstanding may declare the principal amount (or, if any of the Securities are Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof as contemplated by Section 3.01) of all Securities then Outstanding to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon such declaration such principal amount (or specified amount), together with premium, if any, and accrued interest, if any, thereon, shall become immediately due and payable, all subject, however, in the case of an Event of Default described in clause (f) of Section 10.01, to the proviso contained in such clause (f).

At any time after such a declaration of acceleration of the maturity of the Securities then Outstanding shall have been made, but before any sale of any of the Mortgaged Property has been made and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as provided in this Article, the Event or Events of Default giving rise to such declaration of acceleration shall, without further act, be deemed to have been cured, and such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled, if

(a) the Company shall have paid or deposited with the Trustee a sum sufficient to pay

(i) all overdue interest, if any, on all Securities then Outstanding;

78

occurred, the whole amount then due and payable on such Securities for principal and premium, if any, and interest, if any, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 11.07.

No recovery of any such judgment by the Trustee and no levy of any execution upon any such judgment upon any of the Mortgaged Property or any other property of the Company shall affect or impair the Lien of this Indenture upon the Mortgaged Property or any part thereof or any rights, powers or remedies of the Trustee hereunder, or any rights, powers or remedies of the Holders of the Securities.

(a) to file and prove a claim for the whole amount of principal, premium, if any, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for amounts due to the Trustee under Section 11.07) and of the Holders allowed in such judicial proceeding, and

SECTION 10.11 Limitation on Suits.

No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

SECTION 10.13 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holder shall continue as though no such proceeding had been instituted.

SECTION 10.14 Rights and Remedies Cumulative.

Except as otherwise provided in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Anything in this Article to the contrary notwithstanding, the availability of the remedies set forth herein (on an individual or cumulative basis) and the procedures set forth herein relating to the exercise thereof shall be subject to (a) the law (including, for purposes of this paragraph, general principles of equity) of any jurisdiction wherein the Mortgaged Property or any part thereof is located to the extent that such law is mandatorily applicable and (b) the rights of the holder of any Lien prior to the Lien of this Indenture, and, if and to the extent that any provision of this Article conflicts with any provision of such applicable law and/or with the rights of the holder of any such prior Lien, such provision of law and/or the rights of such holder shall control.

SECTION 10.15 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

If an Event of Default shall have occurred and be continuing, the Holders of a majority in principal amount of the Securities then Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee; provided, however, that

(a) such direction shall not be in conflict with any rule of law or with this Indenture, and could not involve the Trustee in personal liability in circumstances where indemnity would not, in the Trustee's sole discretion, be adequate, and

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 10.17 Waiver of Past Defaults.

Before any sale of any of the Mortgaged Property and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as in this Article provided, the Holders of not less than a majority in principal amount of the Securities then Outstanding may on behalf of the Holders of all the Securities then Outstanding waive any past default hereunder and its consequences, except a default

(a) in the payment of the principal of or premium, if any, or interest, if any, on any Security Outstanding, or

(b) in respect of a covenant or provision hereof which under
Section 14.02 cannot be modified or amended without the consent of the Holder of each Outstanding Security of any series or Tranche affected.

Upon any such waiver, such default shall cease to exist, and any and all Events of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 10.18 Undertaking for Costs.

The Company and the Trustee agree, and each Holder of Securities by its acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than ten percentum (10%) in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest, if any, on any Security on or after

83

the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

SECTION 10.19 Waiver of Appraisement and Other Laws.

To the full extent that it may lawfully so agree, the Company shall not at any time set up, claim or otherwise seek to take the benefit or advantage of any appraisement, valuation, stay, extension or redemption law, now or hereafter in effect, in order to prevent or hinder the enforcement of this Indenture or the absolute sale of the Mortgaged Property, or any part thereof, or the possession thereof, or any part thereof, by any purchaser at any sale under this Article; and the Company, for itself and all who may claim under it, so far as it or they now or hereafter may lawfully do so, hereby waives the benefit of all such laws. The Company, for itself and all who may claim under it, waives, to the extent that it may lawfully do so, all right to have the Mortgaged Property marshalled upon any foreclosure of the Lien hereof, and agrees that any court having jurisdiction to foreclose the Lien of this Indenture may order the sale of the Mortgaged Property as an entirety.

SECTION 11.10 Resignation and Removal; Appointment of Successor.

(b) The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 11.11 shall not have been delivered to the Trustee within thirty (30) days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Securities then Outstanding delivered to the Trustee and to the Company.

(ii) the Trustee shall cease to be eligible under Section 11.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (x) the Company by a Board Resolution may remove the Trustee or (y) subject to Section 10.18, any Holder who has been a bona fide Holder for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee or Trustees.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause (other than as contemplated in clause (y) in subsection (d) of this Section), the Company, by a Board Resolution, shall take prompt steps to appoint a successor Trustee or Trustees and shall comply with the applicable requirements of Section 11.11. If, within one (1) year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Securities then Outstanding delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 11.11, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 11.11, any Holder who has been a bona fide Holder of a Security for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) So long as no event which is, or after notice or lapse of time, or both, would become, an Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee (i) a Board Resolution appointing a successor Trustee, effective as of a date specified therein, and (ii) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with Section 11.11, the Trustee shall be deemed to have resigned as contemplated in subsection (b) of this Section, the successor Trustee shall be deemed to have been appointed pursuant to subsection (e) of this Section and such appointment shall be deemed to have been accepted as contemplated in Section 11.11, all as of such date, and all other provisions of this Section and Section 11.11 shall be applicable to such resignation, appointment and acceptance except to the extent inconsistent with this subsection (f).

90

(g) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee and the address of its corporate trust office.

SECTION 11.11 Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all sums owed to it, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its Lien provided for in Section 11.07.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 11.13 Preferential Collection of Claims against Company.

If the Trustee shall be or become a creditor of the Company or any other obligor upon the Securities (other than by reason of a relationship described in Section 311(b) of the Trust Indenture Act), the Trustee shall be subject to any and all applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company or such other obligor. For purposes of Section 3.11(b) of the Trust Indenture Act:

SECTION 11.14 Co-trustees and Separate Trustees.

At any time or times, for the purpose of meeting the legal requirements of any jurisdiction in which any of the Mortgaged Property may at the time be located, the Company and the Trustee shall have power to appoint, and, upon the written request of the Trustee or of the Holders of at least thirty-three percentum (33%) in principal amount of the Securities then Outstanding, the Company shall for such purpose join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee and, if no Event of Default shall have occurred and be continuing, by the Company either to act as co-trustee, jointly with the Trustee, of all or any part of the Mortgaged Property, or to act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons, in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Company does not join in such appointment within fifteen
(15) days after the receipt by it of a request so to do, or if an Event of Default shall have occurred and be continuing, the Trustee alone shall have power to make such appointment.

Should any written instrument or instruments from the Company be required by any co-trustee or separate trustee so appointed to more fully confirm to such co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company.

Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following conditions:

(A) the Securities shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the Trustee;

92

(B) the rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed either by the Trustee or by the Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee;

(C) the Trustee at any time, by an instrument in writing executed by it, with the concurrence of the Company, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, if an Event of Default shall have occurred and be continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section;

(D) neither the Trustee nor any co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(E) any Act of Holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee.

SECTION 11.15 Appointment of Authenticating Agent.

The Trustee may appoint an Authenticating Agent or Agents with respect to the Securities of one or more series, or any Tranche thereof, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series or Tranche issued upon original issuance, exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any State or Territory thereof or the District of Columbia or the Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than Fifty Million Dollars ($50,000,000) and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to

93

the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

The provisions of Sections 3.08, 11.04 and 11.05 shall be applicable to each Authenticating Agent.

If an appointment with respect to the Securities of one or more series, or any Tranche thereof, shall be made pursuant to this Section, the Securities of such series or Tranche may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication substantially in the following form:

94

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

THE BANK OF NEW YORK, as Trustee

By
As Authenticating Agent

By
Authorized Officer

If all of the Securities of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 1.04 and need not be accompanied by an Opinion of Counsel), shall appoint, in accordance with this Section and in accordance with such procedures as shall be acceptable to the Trustee, an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

(d) modify any of the provisions of this Section, Section 6.09 or Section 10.17 with respect to the Securities of any series or any Tranche thereof (except to increase the percentages in principal amount referred to in this Section or such other Sections or to provide that other provisions of this Indenture cannot be modified or waived without the consent of the Holders of all Securities of such series or Tranche) without, in any such case, the consent of the Holder of each Outstanding Security of such series or Tranche; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to "the Trustee" and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Section 14.01(g).

A supplemental indenture which (x) changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of the Holders of, or which is to remain in effect only so long as there shall be Outstanding, Securities of one or more specified series, or one or more Tranches thereof, or (y) modifies the rights of the Holders of Securities of such series or Tranches with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series or Tranche.

It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

SECTION 14.03 Execution of Supplemental Indentures.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 11.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties, immunities or liabilities under this Indenture or otherwise.

SECTION 14.04 Effect of Supplemental Indentures.

Upon the execution and delivery of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. Any supplemental indenture permitted by this Article may restate this Indenture in its entirety, and, upon the execution and delivery thereof, any such restatement shall supersede this Indenture as theretofore in effect for all purposes.

SECTION 14.05 Conformity with Trust Indenture Act.

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

102

SECTION 14.06 Reference in Securities to Supplemental Indentures.

Securities of any series, or any Tranche thereof, authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

SECTION 14.07 Modification Without Supplemental Indenture.

To the extent, if any, that the terms of any particular series of Securities shall have been established in or pursuant to a Board Resolution or an Officer's Certificate pursuant to a supplemental indenture or a Board Resolution as contemplated by Section 3.01, and not in a supplemental indenture, additions to, changes in or the elimination of any of such terms may be effected by means of a supplemental Board Resolution or a supplemental Officer's Certificate, as the case may be, delivered to, and accepted by, the Trustee; provided, however, that such supplemental Board Resolution or supplemental Officer's Certificate shall not be accepted by the Trustee or otherwise be effective unless all conditions set forth in this Indenture which would be required to be satisfied if such additions, changes or elimination were contained in a supplemental indenture shall have been appropriately satisfied. Upon the acceptance thereof by the Trustee, any such supplemental Board Resolution or supplemental Officer's Certificate shall be deemed to be a "supplemental indenture" for purposes of Section 14.04 and 14.06 and a "supplemental indenture", "indenture supplemental" to this Indenture or "instrument" supplemental to this Indenture for purposes of Section 6.08.

The Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which a meeting shall have been called as hereinbefore provided, considered as one class, shall constitute a quorum for a meeting of Holders of Securities of such series and Tranches; provided, however, that if any

104

action is to be taken at such meeting which this Indenture expressly provides may be taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, shall constitute a quorum. In the absence of a quorum within one hour of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series and Tranches, be dissolved. In any other case the meeting may be adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such adjourned meeting. Except as provided by Section 15.05(e), notice of the reconvening of any meeting adjourned for more than thirty (30) days shall be given as provided in Section 1.08 not less than ten (10) days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series and Tranches which shall constitute a quorum.

Except as limited by Section 14.02, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which such meeting shall have been called, considered as one class; provided, however, that, except as so limited, any resolution with respect to any action which this Indenture expressly provides may be taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class.

Any resolution passed or decision taken at any meeting of Holders of Securities duly held in accordance with this Section shall be binding on all the Holders of Securities of the series and Tranches with respect to which such meeting shall have been held, whether or not present or represented at the meeting.

SECTION 15.05 Attendance at Meetings; Determination of Voting Rights; Conduct and Adjournment of Meetings.

(a) Attendance at meetings of Holders of Securities may be in person or by proxy; and, to the extent permitted by law, any such proxy shall remain in effect and be binding upon any future Holder of the Securities with respect to which it was given unless and until specifically revoked by the Holder or future Holder (except as provided in Section 1.06(g)) of such Securities before being voted.

(b) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities in regard to proof of the holding of such Securities and of the appointment of proxies

105

and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations and approved by the Company, the holding of Securities shall be proved in the manner specified in Section 1.06 and the appointment of any proxy shall be proved in the manner specified in Section 1.06. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.06 or other proof.

(c) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 15.02(b), in which case the Company or the Holders of Securities of the series and Tranches calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class.

(d) At any meeting each Holder or proxy shall be entitled to one vote for each One Thousand Dollars ($1,000) principal amount of Outstanding Securities held or represented by such Holder; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security or proxy.

(e) Any meeting duly called pursuant to Section 15.02 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class; and the meeting may be held as so adjourned without further notice.

SECTION 15.06 Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders shall be by written ballots on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities, of the series and Tranches with respect to which the meeting shall have been called, held or represented by them. The permanent chairman of the meeting shall appoint two (2) inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that such notice was given as provided in
Section 15.02 and, if applicable, Section 15.04. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and

106

another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

SECTION 15.07 Action Without Meeting.

In lieu of a vote of Holders at a meeting as hereinbefore contemplated in this Article, any request, demand, authorization, direction, notice, consent, waiver or other action may be made, given or taken by Holders by one or more written instruments as provided in Section 1.05.

EXHIBIT 4.1(c)

NEVADA POWER COMPANY

OFFICER'S CERTIFICATE

I, the undersigned officer of Nevada Power Company (the "Company"), do hereby certify that I am an Authorized Officer of the Company as such term is defined in the Indenture (as defined herein). I am delivering this certificate pursuant to the authority granted in the Board Resolutions of the Company dated May 22, 2001, and Sections 1.04, 2.01, 3.01 and 4.01(a) of the General and Refunding Mortgage Indenture dated as of May 1, 2001 (the "Mortgage Indenture"), as supplemented by a First Supplemental Indenture dated as of May 1, 2001 (the "Supplemental Indenture"; and collectively with the Mortgage Indenture, the "Indenture"), between the Company and The Bank of New York, as Trustee (the "Trustee"). Terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture unless the context clearly requires otherwise. Based upon the foregoing, I hereby certify on behalf of the Company as follows:

1. The terms and conditions of the Securities described in this Officer's Certificate are as follows (the lettered subdivisions set forth in this Paragraph 1 corresponding to the lettered subdivisions of Section 3.01 of the Mortgage Indenture):

(a) The Securities of the first series to be issued under the Indenture shall be designated "8.25% General and Refunding Mortgage Bonds, Series A, due June 1, 2011" (the "Series A Bonds").

(b) There shall be no limit upon the aggregate principal amount of the Series A Bonds that may be authenticated and delivered under the Indenture. The Series A Bonds shall be initially authenticated and delivered in the aggregate principal amount of $350,000,000.

(c) Interest on the Series A Bonds shall be payable to the Persons in whose names such Securities are registered at the close of business on the Regular Record Date for such interest, except as otherwise expressly provided in the form of such Securities attached hereto as Exhibit A.

(d) The Series A Bonds shall mature and the principal thereof shall be due and payable together with all accrued and unpaid interest thereon on June 1, 2011.

(e) The Series A Bonds shall bear interest at the rate of 8.25% per annum. Interest shall accrue on the Series A Bonds from May 24, 2001, or the most recent date to which interest has been paid or duly provided for. The Interest Payment Dates for the Series A Bonds shall be June 1 and December 1 in each year commencing December 1, 2001, and the Regular Record Dates with respect to the Interest Payment Dates for the Series A Bonds shall be May 17 and November 16 in each year, respectively (whether or not a Business Day).

(f) The Corporate Trust Office of The Bank of New York in New York, New York shall be the place at which (i) the principal of, premium and interest on, the Series A


Bonds shall be payable, (ii) registration of transfer of the Series A Bonds may be effected, (iii) exchanges of the Series A Bonds may be effected and (iv) notices and demands to or upon the Company in respect of the Series A Bonds and the Indenture may be served; and The Bank of New York shall be the Security Registrar for the Series A Bonds; provided, however, that the Company reserves the right to change, by one or more Officer's Certificates, any such place or the Security Registrar; and provided, further, that the Company reserves the right to designate, by one or more Officer's Certificates, its principal office in Las Vegas, Nevada as any such place or itself as the Security Registrar; provided, however, that there shall be only a single Security Registrar for the Series A Bonds.

(g) The Series A Bonds shall be redeemable, at the option of the Company, at any time or from time to time, in whole or in part, at a price equal to 100% of the principal amount of the Series A Bonds to be redeemed plus accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on a Regular Record Date occurring prior to such Redemption Date to receive interest paid on the applicable Interest Payment Date ) plus the applicable make-whole premium (the "Make-Whole Premium").

The amount of the Make-Whole Premium with respect to the Series A Bonds (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(i) the sum of the present values, calculated as of the Redemption Date, of:

(A) each interest payment that, but for such redemption, would have been payable on the Series A Bonds (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued and unpaid interest for the period prior to the Redemption Date); and

(B) the principal amount that, but for such redemption, would have been payable at the Stated Maturity of the Series A Bonds (or portion thereof) being redeemed,

over

(ii) the principal amount of the Series A Bonds (or portion thereof) being redeemed.

The present values of each interest and principal payment referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for such redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 30 basis points.

The Make-Whole Premium will be calculated by Credit Suisse First Boston Corporation or, if such firm is unwilling or unable to make such calculation, by an

2

independent investment banking institution of national standing appointed by the Company (in any such case, an "Independent Investment Banker"). The Trustee shall have no responsibility for the calculation of the Make-Whole Premium and may conclusively presume the correctness of such calculation.

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Series A Bonds, calculated to the nearest 1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as of the third business day immediately preceding the applicable Redemption Date.

The weekly average yields of United States Treasury Notes will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield will be equal to such weekly average yield. In all other cases, the Treasury Yield will be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200 of 1% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield will be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

If less than all of the Series A Bonds are to be redeemed, the Security Registrar will select the Series A Bonds to be redeemed by such method as the Security Registrar shall deem fair and appropriate. The Trustee may select for redemption Series A Bonds and portions of Series A Bonds in amounts of $1,000 or whole multiples of $1,000; subject to clause (i) of this Paragraph 1 (as to minimum denominations).

(h) Not applicable.

(i) The Series A Bonds are issuable only in denominations of $250,000 and integral multiples of $1000 in excess thereof.

(j) Not applicable.

(k) Not applicable.

(l) Not applicable.

(m) Not applicable.

3

(n) Not applicable.

(o) Pursuant to the terms of a registration rights agreement with one or more of the initial purchasers of the Series A Bonds (a "Registration Rights Agreement"), the Company has agreed to file an exchange offer registration statement to exchange the Series A Bonds for substantially identical Securities registered under the Securities Act of 1933, as amended (the "Securities Act") as evidence of the same underlying indebtedness. Unless otherwise specified by the Company in a supplement to this Officer's Certificate, the Securities so registered and offered and issued in exchange shall be additional Series A Bonds. The Company has also agreed to file a shelf registration statement to cover resales of the Series A Bonds, as initially issued and sold, under certain circumstances. If the Company fails to satisfy those obligations, the Company has agreed to pay liquidated damages to the holders of the Series A Bonds under certain circumstances. The terms relating to the exchange of the Series A Bonds are set forth in the Registration Rights Agreement attached hereto as Exhibit B.

(p) Not applicable.

(q) Certificates representing Series A Bonds offered and sold in reliance on Rule 144A (and only such Series A Bonds) shall be in the form of a permanent certificate in global form (a "Global Certificate") registered in the name of Cede & Co., as nominee for The Depository Trust Company (the "Depositary"), to be delivered to the Depositary or its custodian, by or on behalf of the Company. The Global Certificate shall not be transferable or exchangeable, nor shall any purported transfer be registered, except as follows:

(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

(ii) the Global Certificate may be exchanged for Series A Bonds in the form of definitive certificates, registered in the respective names of the beneficial owners thereof, and thereafter shall be transferable without restriction, if:

(A) the Depositary, or any successor securities depositary, shall have notified the Company and the Trustee that (i) it is unwilling or unable to continue to act as securities depositary with respect to the Series A Bonds, (ii) has ceased to be qualified to act as such, or
(iii) has ceased to be a clearing agency registered under the Exchange Act, and the Trustee shall not have been

notified by the Company within ninety (90) days of the identity of a successor securities depositary with respect to such Securities;

4

(B) the Company shall have delivered to the Trustee a Company Order to the effect that the Company has elected to terminate the book-entry system; or

(C) an Event of Default shall have occurred and be continuing.

Unless and until definitive, fully registered certificates shall have been issued to beneficial owners as provided in subclause (ii) of this clause (g) of Paragraph 1 hereof:

(a) the provisions of this clause (q) shall be in full force and effect;

(b) the Company and the Trustee and any agent of either shall be entitled to deal with the Depositary for all purposes of the indenture and such Series A Bonds (including payment of principal of, and premium and interest thereon, the giving of notice and receiving approvals, votes or consents thereunder) as the Holder of such Securities and the sole holder of the Global Certificate and shall have no obligation to the beneficial owners of such Securities;

(c) to the extent that the provisions of clause (q) of paragraph 1 conflicts with any other provisions of the Indenture or the Series A Bonds, 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. The Depositary will make book-entry transfers among depositary participants and receive and transmit payments of principal, premium and interest, if any, to such depositary participants.

Notwithstanding the foregoing, with respect to any Global Certificate, nothing contained herein or in the Indenture shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary (or its nominee), as a Holder, with respect to such Global Certificate or impair, as between such Depositary and the related beneficial owner, the operation of customary practices governing the exercise of rights of the Depositary (or its nominee) as Holder of such global certificate. Except for the Global Certificate, any and all of the Series A Bonds shall be in the form of a non-global, definitive physical certificate.

(r) Not applicable.

(s) The Series A Bonds 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 A Bonds, or any Tranche thereof; provided, however,

5

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 A Bonds, "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.

(u) Notwithstanding the provisions of Section 9.01 of the Indenture, no Series A Bond shall be deemed to have been paid, and the indebtedness of the Company in respect thereof deemed to have been satisfied and discharged as contemplated therein, unless the Company shall have delivered to the Trustee either:

(i) an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of the Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm 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; or

(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 A Bonds 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.

2. All conditions precedent provided for in the Mortgage Indenture and the Indenture (including any covenants compliance with which constitutes a condition precedent)

6

relating to the execution and delivery of the Supplemental Indenture and the authentication and delivery of the Series A Bonds have been complied with.

NEVADA POWER COMPANY, a corporation duly organized and existing under the laws of the State of Nevada (herein called the "Company," which term includes any successor corporation under the Indenture referred to below), for value received, hereby promises to pay to

****Cede & Co.****

, or registered assigns, the principal sum of THREE HUNDRED FIFTY MILLION DOLLARS on the Stated Maturity specified above, and to pay interest thereon from the Original Interest Accrual Date specified above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment Dates specified above in each year, commencing with the second Interest Payment Date next succeeding the Original Interest Accrual Date specified above, and at Maturity, at the Interest Rate per annum specified above, until the principal hereof is paid or duly provided for. The interest so payable, and paid or duly provided for, on any Interest Payment Date shall, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date specified above (whether or not a Business Day) next preceding such Interest Payment Date. Notwithstanding the foregoing, interest payable at Maturity shall be paid to the Person to whom principal shall be paid. 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.

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.

If any Interest Payment Date, any Redemption Date or the Stated Maturity shall not be a Business Day (as hereinafter defined), payment of the amounts due on this Security on such date may be made on the next succeeding Business Day; and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on such amounts for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day.

This Security is subject to redemption, at the option of the Company, at any time or from time to time, in whole or in part, at a price equal to 100% of the principal amount of this Security (or the portion hereof to be redeemed) plus accrued and unpaid interest to the Redemption Date plus the applicable make-whole premium (the "Make-Whole Premium").

The amount of the Make-Whole Premium with respect to the Securities of this series (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(a) the sum of the present values, calculated as of the Redemption Date, of:

(1) each interest payment that, but for such redemption, would have been payable on such Securities (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued and unpaid interest for the period prior to the Redemption Date); and

(2) the principal amount that, but for such redemption, would have been payable at the Stated Maturity of such Securities (or portion thereof) being redeemed,

2

over

(b) the principal amount of such Securities (or portion thereof) being redeemed.

The present values of each interest and principal payment referred to in clause (a) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for such redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 30 basis points.

The Make-Whole Premium will be calculated by Credit Suisse First Boston Corporation or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Company (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Securities, calculated to the nearest 1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as of the third business day immediately preceding the applicable Redemption Date.

The weekly average yields of United State Treasury Notes will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield will be equal to such weekly average yield. In all other cases, the Treasury Yield will be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200 of 1% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield will be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

If less than all of the Securities are to be redeemed, the Securities Registrar will select the Securities to be redeemed by such method as the Trustee shall deem fair and appropriate. The Securities Registrar may select for redemption Securities and portions of Securities in amounts of $1,000 or whole multiples of $1,000.

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

Notice of redemption shall be given by mail to Holders of Securities, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the Trustee of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security.

3

In the event of redemption of this Security in part only, a new Security or Securities of this series, of like tenor, for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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.

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 $250,000 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

4

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 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.

(i) there shall be deducted from the Cost or Fair Value to the Company thereof, as the case may be (as of the date so certified), an amount equal to the Cost (or as to Property Additions of which the Fair Value to the Company at the time the same became Funded Property was certified to be an amount less than the Cost as determined pursuant to this Section, then such Fair Value, as so certified, in lieu of Cost) of all Funded Property of the Company retired to the date of such certification (other than the Funded Property, if any, in connection with the application for the release of which such certificate is filed) and not theretofore deducted from the Cost or Fair Value to the Company of Property Additions theretofore certified to the Trustee, and

(A) the principal amount of any obligations secured by Purchase Money Lien, not theretofore so added and which the Company then elects so to add, which shall theretofore have been delivered to the Trustee or the trustee or other holder of a Lien prior to the Lien of this Indenture as the basis of the release of Funded Property retired from the Lien of this Indenture or such prior Lien, as the case may be;

(B) ten-sevenths (10/7) of the amount of any cash, not theretofore so added and which the Company then elects so to add, which shall theretofore have been delivered to the Trustee or the trustee or other holder of a

21

Lien prior to the Lien of this Indenture as the proceeds of insurance on Funded Property retired (to the extent of the portion thereof deemed to be Funded Cash) or as the basis of the release of Funded Property retired from the Lien of this Indenture or from such prior Lien, as the case may be;

(C) ten-sevenths (10/7) of the principal amount of any Security or Securities, or portion of such principal amount, not theretofore so added and which the Company then elects so to add,
(I) which shall theretofore have been delivered to the Trustee as the basis of the release of Funded Property retired or (II) the right to the authentication and delivery of which under the provisions of Section 4.03 shall at any time theretofore have been waived under Section 8.03(d)(iii) as the basis of the release of Funded Property retired;

(D) the Cost or Fair Value to the Company (whichever shall be less), after making any deductions and any additions pursuant to this Section, of any Property Additions, not theretofore so added and which the Company then elects so to add, which shall theretofore have been made the basis of the release of Funded Property retired (such Fair Value to be the amount shown in the Expert's Certificate delivered to the Trustee in connection with such release); and

(E) the Cost to the Company of any Property Additions (including Property Additions subject to the Lien of the SPPC 1940 Mortgage) not theretofore so added and which the Company then elects so to add, to the extent that the same shall have been substituted for Funded Property retired;

provided, however, that the aggregate of the amounts added under clause
(ii) above shall in no event exceed the amounts deducted under clause (i) above.

(c) Except as otherwise provided in Section 8.03, the term "Cost" with respect to Property Additions shall mean the sum of (i) any cash delivered in payment therefor or for the acquisition thereof, (ii) an amount equivalent to the fair market value in cash (as of the date of delivery) of any securities or other property delivered in payment therefor or for the acquisition thereof,
(iii) the principal amount of any obligations secured by prior Lien (other than the SPPC 1940 Mortgage) upon such Property Additions outstanding at the time of the acquisition thereof, (iv) the principal amount of any other obligations incurred or assumed in connection with the payment for such Property Additions or for the acquisition thereof and (v) any other amounts which, in accordance with generally accepted accounting principles, are properly charged or chargeable to the plant or other property accounts of the Company with respect to such Property Additions as part of the cost of construction or acquisition thereof, including, but not limited to, any allowance for funds used during construction or any similar or analogous amount; provided, however, that, notwithstanding any other provision of this Indenture,

(x) with respect to Property Additions owned by a successor corporation immediately prior to the time it shall have become such by consolidation or merger or acquired by a successor corporation in or as a result of a consolidation or merger (excluding, in any case, Property Additions owned by the Company immediately prior to such time), Cost shall mean the amount or amounts at which such Property

22

Additions are recorded in the plant or other property accounts of such successor corporation, or the predecessor corporation from which such Property Additions are acquired, as the case may be, immediately prior to such consolidation or merger;

(y) with respect to Property Additions which shall have been acquired (otherwise than by construction) by the Company without any consideration consisting of cash, securities or other property or the incurring or assumption of indebtedness, no determination of Cost shall be required, and, wherever in this Indenture provision is made for Cost or Fair Value, Cost with respect to such Property Additions shall mean an amount equal to the Fair Value to the Company thereof or, if greater, the aggregate amount reflected in the Company's books of account with respect thereto upon the acquisition thereof; and

(z) in no event shall the Cost of Property Additions be required to reflect any depreciation or amortization in respect of such Property Additions, or any adjustment to the amount or amounts at which such Property Additions are recorded in plant or other property accounts due to the non-recoverability of investment or otherwise.

If any Property Additions are shown by the Expert's Certificate provided for in Section 4.02 (b)(ii) to include property which has been used or operated by others than the Company in a business similar to that in which it has been or is to be used or operated by the Company, the Cost thereof need not be reduced by any amount in respect of any goodwill, going concern value rights and/or intangible property simultaneously acquired for which no separate or distinct consideration shall have been paid or apportioned, and in such case the term Property Additions as defined herein may include such goodwill, going concern value rights and intangible property.

Except as otherwise expressly provided in this Indenture, upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officer's Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, it being understood that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished.

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

SECTION 1.05 Content and Form of Documents Delivered to Trustee.

(a) Any Officer's Certificate may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and, insofar as it relates to or is dependent upon matters which are subject to verification by Accountants, upon a certificate or opinion of, or representations by, an Accountant, and, insofar as it relates to or is dependent upon matters which are required in this Indenture to be covered by a certificate or opinion of, or representations by, an Expert, upon the certificate or opinion of, or representations by, an Expert, unless, in any case, such officer has actual knowledge that the certificate or opinion or representations with respect to the matters upon which such Officer's Certificate may be based as aforesaid are erroneous.

Any Expert's Certificate may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company and which are not subject to verification by Experts, upon a certificate or opinion of, or representations by, an officer or officers of the Company, unless such Expert has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion may be based as aforesaid are erroneous.

Any certificate of an Accountant may be based (without further examination or investigation), insofar as it relates to or is dependent upon legal matters, upon an opinion of, or representations by, counsel, and insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company and which are not subject to verification by Accountants, upon a certificate of, or representations by, an officer or officers of the Company, unless such Accountant has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion may be based as aforesaid are erroneous.

Any Opinion of Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon factual matters, information with respect to which is in the possession of the Company, upon a certificate of, or representations by, an officer or officers of the Company, and, insofar as it relates to or is dependent upon matters which are subject to verification by Accountants upon a certificate or opinion of, or representations by, an Accountant, and, insofar as it relates to or is dependent upon matters required in this Indenture to be covered by a certificate or opinion of, or representations by, an Expert, upon the certificate or opinion of, or representations by, an Expert, unless such counsel has actual knowledge that the certificate or opinion or representations with respect to the matters upon which his opinion may be based as aforesaid are erroneous. In addition, any Opinion of

24

Counsel may be based (without further examination or investigation), insofar as it relates to or is dependent upon matters covered in an Opinion of Counsel rendered by other counsel, upon such other Opinion of Counsel, unless such counsel has actual knowledge that the Opinion of Counsel rendered by such other counsel with respect to the matters upon which his Opinion of Counsel may be based as aforesaid are erroneous. Further, any Opinion of Counsel with respect to the status of title to or the sufficiency of descriptions of property, and/or the existence of Liens thereon, and/or the recording or filing of documents, and/or any similar matters, may be based (without further examination or investigation) upon (i) title insurance policies or commitments and reports, lien search certificates and other similar documents or (ii) certificates of, or representations by, officers, employees, agents and/or other representatives of the Company or (iii) any combination of the documents referred to in (i) and

If, in order to render any Opinion of Counsel provided for herein, the signer thereof shall deem it necessary that additional facts or matters be stated in any Officer's Certificate, certificate of an Accountant or Expert's Certificate provided for herein, then such certificate may state all such additional facts or matters as the signer of such Opinion of Counsel may request.

(b) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

(c) Whenever, subsequent to the receipt by the Trustee of any Board Resolution, Officer's Certificate, Expert's Certificate, Net Earnings Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or instrument may be substituted therefor in corrected form with the same force and effect as if originally filed in the corrected form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding, if any such corrective document or instrument indicates that action has been taken by or at the request of the Company which could not have been taken had the original document or instrument not contained such error or omission, the action so taken shall not be invalidated or otherwise rendered ineffective but shall be and remain in full force and effect, except to the extent that such action was a result of willful misconduct or bad faith. Without limiting the generality of the foregoing, any Securities issued under the authority of such defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefit of the Lien of this Indenture equally and ratably with all other Outstanding Securities, except as aforesaid.

25

SECTION 1.06 Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the record of Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article XV, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 11.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders shall be proved in the manner provided in Section 15.06.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be proved in any other manner which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

(c) The principal amount (except as otherwise contemplated in clause
(y) of the first proviso to the definition of Outstanding) and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of a Holder shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

(e) Until such time as written instruments shall have been delivered to the Trustee with respect to the requisite percentage of principal amount of Securities for the action contemplated by such instruments, any such instrument executed and delivered by or on behalf of a Holder may be revoked with respect to any or all of such Securities by written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven.

(f) Securities of any series, or any Tranche thereof, authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear a notation in

26

form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

(g) The Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or other Act solicited by the Company, but the Company shall have no obligation to do so. In addition, the Trustee may, at its option, fix in advance a record date for the determination of Holders entitled to join in the giving or making of any Notice of Default, any declaration of acceleration referred to in Section 10.02, any request to institute proceedings referred to in Section 10.11 or any direction referred to in Section 10.16. If any such record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act, or such notice, declaration, request or direction, may be given before or after such record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for the purposes of determining (i) whether Holders of the requisite proportion of the Outstanding Securities have authorized or agreed or consented to such Act (and for that purpose the Outstanding Securities shall be computed as of the record date) and/or (ii) which Holders may revoke any such Act (notwithstanding subsection (e) of this Section).

SECTION 1.07 Notices, Etc. to Trustee and Company.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

Any notice required by this Indenture may be waived in writing by the Person entitled to receive such notice, either before or after the event otherwise to be specified therein, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 1.09 Conflict with Trust Indenture Act.

If any provision of this Indenture limits, qualifies or conflicts with another provision hereof which is required or deemed to be included in this Indenture by, or is otherwise governed by, any provision of the Trust Indenture Act, such other provision shall control; and if any provision hereof otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.

SECTION 1.15 Legal Holidays.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities other than a provision in Securities of any series, or any Tranche thereof, or in the indenture supplemental hereto, Board Resolution or Officer's Certificate which establishes the terms of the Securities of such series or Tranche, which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal and premium, if any, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day.

Such Investment Securities shall be held subject to the same provisions hereof as the cash used to purchase the same, but upon a like request of the Company shall be sold, in whole or in designated part, and the proceeds of such sale shall be held subject to the same provisions hereof as the cash used to purchase the Investment Securities so sold. If such sale shall produce a net sum less than the cost of the Investment Securities so sold, the Company shall pay to the Trustee or any such Paying Agent, as the case may be, such amount in cash as, together with the net proceeds from such sale, shall equal the cost of the Investment Securities so sold, and if such sale shall produce a net sum greater than the cost of the Investment Securities so sold, the Trustee or any such Paying Agent, as the case may be, shall promptly pay over to the Company an amount in cash equal to such excess, free and clear of any Lien. In no event shall the Trustee be liable for any loss incurred in connection with the sale of any Investment Security pursuant to this Section.

Notwithstanding the foregoing, if an Event of Default shall have occurred and be continuing, interest on Investment Securities and any gain upon the sale thereof shall be held as part of the Mortgaged Property until such Event of Default shall have been cured or waived, whereupon such interest and gain shall be promptly paid over to the Company free and clear of any Lien.

(j) the currency or currencies, including composite currencies, in which payment of the principal of and premium, if any, and interest, if any, on the Securities of such series, or any Tranche thereof, shall be payable (if other than in Dollars); it being understood that, for purposes of calculations under this Indenture (including calculations of principal amount under Article

(m) if the amount payable in respect of principal of or premium, if any, or interest, if any, on the Securities of such series, or any Tranche thereof, may be determined with reference to an index or other fact or event ascertainable outside of this Indenture, the manner in which such amounts shall be determined (to the extent not established pursuant to clause (e) of this paragraph); it being understood that all calculations under this Indenture (including calculations of principal amount under Article IV) shall be made on the basis of the amount that would be payable as principal if such principal were due, or on the basis of the interest rates in effect, as the case may be, on the date next preceding the date of such calculation;

Anything herein to the contrary notwithstanding, the Trustee shall be under no obligation to authenticate and deliver Securities of any series the terms of which, established as contemplated by this Section, would affect the rights, duties, obligations, liabilities or immunities of the Trustee under this Indenture or otherwise.

SECTION 3.02 Denominations.

Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, the Securities of each series shall be issuable in denominations of One Thousand Dollars ($1,000) and any integral multiple thereof.

SECTION 3.03 Execution, Dating, Certificate of Authentication.

Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, the Securities shall be executed on behalf of the

34

Company by an Authorized Officer, and may have the corporate seal of the Company affixed thereto or reproduced thereon and attested by any other Authorized Officer. The signature of any or all of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at the time of execution Authorized Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

Unless otherwise specified as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, each Security shall be dated the date of its authentication.

Unless otherwise specified as contemplated by Section 3.01 with respect to any series of Securities, or any Tranche thereof, no Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature of an authorized officer thereof, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if (a) any Security shall have been authenticated and delivered hereunder to the Company, or any Person acting on its behalf, but shall never have been issued and sold by the Company, (b) the Company shall deliver such Security to the Security Registrar for cancellation or shall cancel such Security and deliver evidence of such cancellation to the Trustee, in each case as provided in Section 3.09, and (c) the Company, at its election, shall deliver to the Trustee a written statement (which need not comply with Section 1.04 and need not be accompanied by an Officer's Certificate or an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, then, for all purposes of this Indenture, such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits hereof.

SECTION 3.04 Temporary Securities.

Pending the preparation of definitive Securities of any series, or any Tranche thereof, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed, photocopied or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities; provided, however, that temporary Securities need not recite specific redemption, sinking fund, conversion or exchange provisions.

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, after the preparation of definitive Securities of such series or Tranche, the temporary Securities of such series or Tranche shall be exchangeable, without charge to the Holder thereof, for definitive Securities of such series or Tranche upon

35

surrender of such temporary Securities at the office or agency of the Company maintained pursuant to Section 6.02 in a Place of Payment for such Securities. Upon such surrender of temporary Securities, the Company shall, except as aforesaid, execute and the Trustee shall authenticate and deliver in exchange therefor definitive Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

Until exchanged in full as hereinabove provided, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and Tranche and of like tenor authenticated and delivered hereunder.

SECTION 3.05 Registration, Registration of Transfer and Exchange.

The Company shall cause to be kept in one of the offices designated pursuant to Section 6.02, with respect to the Securities of each series, or any Tranche thereof, a register (the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of such series or Tranche and the registration of transfer thereof. The Company shall designate one Person to maintain the Security Register for the Securities of each series, and such Person is referred to herein, with respect to such series, as the "Security Registrar". Anything herein to the contrary notwithstanding, the Company may designate one or more of its offices as an office in which a register with respect to the Securities of one or more series, or any Tranche or Tranches thereof, shall be maintained, and the Company may designate itself the Security Registrar with respect to one or more of such series. The Security Register shall be open for inspection by the Trustee and the Company at all reasonable times.

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, upon surrender for registration of transfer of any Security of such series or Tranche at the office or agency of the Company maintained pursuant to Section 6.02 in a Place of Payment for such series or Tranche, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

Except as otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, any Security of such series or Tranche may be exchanged at the option of the Holder, for one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities delivered upon any registration of transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

36

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee or the Security Registrar) be duly endorsed or shall be accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Security Registrar, as the case may be, duly executed by the Holder thereof or his attorney duly authorized in writing.

Unless otherwise specified as contemplated by Section 3.01 with respect to Securities of any series, or any Tranche thereof, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 5.06 or 14.06 not involving any transfer.

The Company shall not be required to execute or to provide for the registration of transfer of or the exchange of (a) Securities of any series, or any Tranche thereof, during a period of fifteen (15) days immediately preceding the date notice is to be given identifying the serial numbers of the Securities of such series or Tranche called for redemption or (b) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the ownership of and the destruction, loss or theft of any Security and (b) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security is held by a Person purporting to be the owner of such Security, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

Notwithstanding the foregoing, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, but subject to compliance with the foregoing conditions, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an additional contractual obligation of the

37

Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone other than the Holder of such new Security, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.07 Payment of Interest; Interest Rights Preserved.

Unless otherwise specified as contemplated by Section 3.01 with respect to the Securities of any series, or any Tranche thereof, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the related Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a date (herein called a "Special Record Date") for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than thirty (30) days and not less than ten (10) days prior to the date of the proposed payment and not less than twenty-five (25) days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall, not less than fifteen (15) days prior to such Special Record Date, cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date.

(b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any

38

securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.08 Persons Deemed Owners.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Sections 3.05 and 3.07) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.09 Cancellation by Security Registrar.

All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Security Registrar, be delivered to the Security Registrar and, if not theretofore canceled, shall be promptly canceled by the Security Registrar. The Company may at any time deliver to the Security Registrar for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever or which the Company shall not have issued and sold, and all Securities so delivered shall be promptly canceled by the Security Registrar. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.09, except as expressly permitted by this Indenture. All canceled Securities held by the Security Registrar shall be disposed of in accordance with the Security Registrar's then customary practice for disposing of securities, unless otherwise directed by a Company Order; provided, however, that the Trustee shall not be required to destroy any canceled Securities.

SECTION 3.10 Computation of Interest.

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, or any Tranche thereof, interest on the Securities of each series shall be computed on the basis of a three hundred sixty (360) day year consisting of twelve (12) thirty (30) day months and, with respect to any period less than a full calendar month, on the basis of the actual number of days elapsed during such period.

SECTION 3.11 Payment to Be in Proper Currency.

In the case of the Securities of any series, or any Tranche thereof, denominated in any currency other than Dollars or in a composite currency (the "Required Currency"), except as otherwise specified with respect to such Securities as contemplated by Section 3.01, the obligation of the Company to make any payment of the principal thereof, or the premium, if any,

39

or interest, if any, thereon, shall not be discharged or satisfied by any tender by the Company, or recovery by the Trustee, in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and payable. If any such tender or recovery is in a currency other than the Required Currency, the Trustee may take such actions as it considers appropriate to exchange such currency for the Required Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of Required Currency then due and payable, and in no circumstances shall the Trustee be liable therefor except in the case of its negligence or willful misconduct.

SECTION 3.12 CUSIP Numbers.

The Company in issuing the Securities may use "CUSIP" or other similar numbers (if then generally in use), and, if so, the Trustee or Security Registrar may use "CUSIP" or such other numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, in which case none of the Company or, as the case may be, the Trustee or the Security Registrar, or any agent of any of them, shall have any liability in respect of any CUSIP number used on any such notice, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers.

are to be promptly confirmed electronically or in writing), in either case in accordance with the instrument or instruments delivered pursuant to clause (a) above;

(c) the Securities of such series, executed on behalf of the Company by an Authorized Officer;

(iii) when such Securities shall have been authenticated and delivered by the Trustee and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, such Securities will constitute valid obligations of the Company, entitled to the benefit of the Lien of this Indenture equally and ratably with all other Securities then Outstanding;

provided, however, that, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive such Opinion of Counsel only once at or prior to the time of the first authentication and delivery of such Securities (provided that such Opinion of Counsel addresses the authentication and delivery of all such Securities) and that, in lieu of the opinions described in clauses (ii) and (iii) above, counsel may opine that:

(x) when the terms of such Securities shall have been established pursuant to a Company Order or Orders or pursuant to such procedures as may be specified from time to time by a Company Order or Orders, all as contemplated by and in accordance with the instrument or instruments delivered pursuant to clause (a) above, such terms will have been duly authorized by the Company and will have been established in conformity with the provisions of this Indenture; and

REDEMPTION OF SECURITIES

SECTION 5.01 Applicability of Article.

Securities of any series, or any Tranche thereof, which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for Securities of such series or Tranche) in accordance with this Article.

SECTION 5.02 Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or an Officer's Certificate. The Company shall, at least forty-five (45) days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of such Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officer's Certificate evidencing compliance with such restriction or condition.

46

SECTION 5.03 Selection of Securities to Be Redeemed.

If less than all the Securities of any series, or any Tranche thereof, are to be redeemed, the particular Securities to be redeemed shall be selected by the Security Registrar from the Outstanding Securities of such series or Tranche not previously called for redemption, by such method as shall be provided for any particular series or Tranche, or, in the absence of any such provision, by such method of random selection as the Security Registrar shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of such series or Tranche or any integral multiple thereof) of the principal amount of Securities of such series or Tranche having a denomination larger than the minimum authorized denomination for Securities of such series or Tranche; provided, however, that if, as indicated in an Officer's Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and less than all of such Securities as to which such offer was made shall have been tendered to the Company for such purchase, the Security Registrar, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered.

The Security Registrar shall promptly notify the Company and the Trustee in writing of the Securities selected for redemption and, in the case of any Securities selected to be redeemed in part, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

SECTION 5.04 Notice of Redemption.

Notice of redemption shall be given in the manner provided in
Section 1.08 to the Holders of the Securities to be redeemed not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date.

All notices of redemption shall state:

(a) the Redemption Date,

(b) the Redemption Price,

(c) if less than all the Securities of any series or Tranche are to be redeemed, the identification of the particular Securities to be redeemed and the portion of the principal amount of any Security to be redeemed in part,

(d) that on the Redemption Date the Redemption Price, together with accrued interest, if any, to the Redemption Date, will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

47

(e) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any, unless it shall have been specified as contemplated by Section 3.01 with respect to such Securities that such surrender shall not be required,

(f) that the redemption is for a sinking or other fund, if such is the case, and

(g) such other matters as the Company shall deem desirable or appropriate.

With respect to any notice of redemption of Securities at the election of the Company, unless, upon the giving of such notice, such Securities shall be deemed to have been paid in accordance with Section 9.01, such notice may state that such redemption shall be conditional upon the receipt by the Paying Agent or Agents for such Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made, and the Paying Agent or Agents for the Securities otherwise to have been redeemed shall promptly return to the Holders thereof any of such Securities which had been surrendered for payment upon such redemption.

Notice of redemption of Securities to be redeemed at the election of the Company, and any notice of non-satisfaction of a condition for redemption as aforesaid, shall be given by the Company or, at the Company's request, by the Security Registrar in the name and at the expense of the Company. Notice of mandatory redemption of Securities shall be given by the Security Registrar in the name and at the expense of the Company.

SECTION 5.05 Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities or portions thereof so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless, in the case of an unconditional notice of redemption, the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security or portion thereof shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that no such surrender shall be a condition to such payment if so specified as contemplated by Section 3.01 with respect to such Security; and provided, further, that, except as otherwise specified as contemplated by Section 3.01 with respect to such Security, any installment of interest on any Security the Stated Maturity of which installment is on or prior to the Redemption Date shall be payable to the Holder of such Security, or one or more Predecessor Securities, registered as such at the close of

48

business on the related Regular Record Date according to the terms of such Security and subject to the provisions of Section 3.07.

SECTION 5.06 Securities Redeemed in Part.

Upon the surrender of any Security which is to be redeemed only in part at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities of the same series and Tranche, of any authorized denomination requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency and prompt notice to the Holders of any such change in the manner specified in Section 1.08.

The Company may also from time to time designate one or more other offices or agencies with respect to the Securities of one or more series, or any Tranche thereof, for any or all of the foregoing purposes and may from time to time rescind such designations; provided, however, that, unless otherwise specified as contemplated by Section 3.01 with respect to the Securities of such series or Tranche, no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes in each Place of Payment for such Securities in accordance with the requirements set forth above. The Company shall give prompt written notice to the Trustee, and prompt notice to the Holders in the manner specified in Section 1.08, of any such designation or rescission and of any change in the location of any such other office or agency.

Anything herein to the contrary notwithstanding, any office or agency required by this Section may be maintained at an office of the Company, in which event the Company shall perform all functions to be performed at such office or agency.

SECTION 6.03 Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on any of such Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company shall promptly notify the Trustee of any failure by the Company (or any other obligor on such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities.

Whenever the Company shall have one or more Paying Agents for the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on such Securities, deposit with such Paying Agents sums sufficient (without duplication) to pay the principal and premium or interest so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of any failure by it so to act.

The Company shall cause each Paying Agent for the Securities of any series, or any Tranche thereof, other than the Company or the Trustee, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

The Company may at any time pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a Company Order delivered to the Trustee, in accordance with the provisions of Article IX; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on Company Request, or, if then held by the Company, shall be discharged from such trust; and, upon such payment or discharge, the Holder of such Security shall, as an unsecured general creditor and not as the Holder of an Outstanding Security, look only to the Company for payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment to the Company, shall, upon receipt of a Company Request and at the expense of the Company, cause to be mailed, on one occasion only, notice to such Holder that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such mailing, any unclaimed balance of such money then remaining will be paid to the Company.

51

selling, transferring or otherwise disposing of, or causing the sale, transfer or other disposition of, any portion of the Mortgaged Property.

SECTION 6.06 Payment of Taxes; Discharge of Liens.

The Company shall pay all taxes and assessments and other governmental charges lawfully levied or assessed upon the Mortgaged Property, or upon any part thereof, or upon the interest of the Trustee in the Mortgaged Property, before the same shall become delinquent, and shall make reasonable effort to observe and conform in all material respects to all valid requirements of any Governmental Authority relative to any of the Mortgaged Property and all covenants, terms and conditions upon or under which any of the Mortgaged Property is held; and the Company shall not suffer any Lien to be created upon the Mortgaged Property, or any part thereof, prior to the Lien hereof, other than Permitted Liens and other than, in the case of property hereafter acquired, Purchase Money Liens and any other Liens existing or placed thereon at the time of the acquisition thereof; provided, however, that nothing in this Section contained shall require the Company (i) to observe or conform to any requirement of Governmental Authority or to cause to be paid or discharged, or to make provision for, any such Lien, or to pay any such tax, assessment or governmental charge so long as the validity thereof shall be contested in good faith and by appropriate legal proceedings, (ii) to pay, discharge or make provisions for any tax, assessment or other governmental charge, the validity of which shall not be so contested if adequate security for the payment of such tax, assessment or other governmental charge and for any penalties or interest which may reasonably be anticipated from failure to pay the same shall be given to the Trustee or
(iii) to pay, discharge or make provisions for any Liens existing on the Mortgaged Property at the date of execution and delivery of this Indenture, as originally executed and delivered; and provided, further, that nothing in this
Section shall prohibit the issuance or other incurrence of additional indebtedness, or the refunding of outstanding indebtedness, secured by any Lien prior to the Lien hereof which is permitted under this Section to continue to exist.

SECTION 6.07 Insurance.

(a) The Company shall (i) keep or cause to be kept all the property subject to the Lien of this Indenture insured against loss by fire, to the extent that property of similar character is usually so insured by companies similarly situated and operating like properties, to a reasonable amount, by reputable insurance companies, the proceeds of such insurance (except as to any loss of Excepted Property and except as to any particular loss less than the greater of (A) Ten Million Dollars ($10,000,000) and (B) three percentum (3%) of the sum of (1) the principal amount of Securities Outstanding on the date of such particular loss and (2) the principal amount of the First Mortgage Bonds Outstanding on the date of such particular loss) to be made payable, subject to applicable law, to the Trustee as the interest of the Trustee may appear, to the trustee of the SPPC 1940 Mortgage, or to the trustee or other holder of any other Lien prior hereto upon property subject to the Lien hereof, if the terms thereof require such payment or (ii) in lieu of or supplementing such insurance in whole or in part, adopt some other method or plan of protection against loss by fire at least equal in protection to the method or plan of protection against loss by fire of companies similarly situated and operating properties subject to similar fire hazards or properties on which an equal primary fire insurance rate has been set by reputable insurance companies; and if the Company shall adopt such other method or plan of

52

protection, it shall, subject to applicable law (and except as to any loss of Excepted Property and except as to any particular loss less than the greater of (X) Ten Million Dollars ($10,000,000) and (Y) three percentum (3%) of the sum of
(1) the principal amount of Securities Outstanding on the date of such particular loss and (2) the principal amount of the First Mortgage Bonds Outstanding on the date of such particular loss) pay to the Trustee on account of any loss covered by such method or plan an amount in cash equal to the amount of such loss less any amounts otherwise paid to the Trustee in respect of such loss or paid to the trustee under the SPPC 1940 Mortgage or to the trustee or other holder of any other Lien prior hereto upon property subject to the Lien hereof in respect of such loss if the terms thereof require such payment. Any cash so required to be paid by the Company pursuant to any such method or plan shall for the purposes of this Indenture be deemed to be proceeds of insurance. In case of the adoption of such other method or plan of protection, the Company shall also furnish to the Trustee a certificate of an actuary or other qualified person appointed by the Company with respect to the adequacy of such method or plan.

Anything herein to the contrary notwithstanding, the Company may have fire insurance policies with (i) a deductible provision in a dollar amount per occurrence not exceeding the greater of (A) Ten Million Dollars ($10,000,000) and (B) three percentum (3%) of the sum of (1) the principal amount of the Securities Outstanding on the date such policy goes into effect and (2) the principal amount of the First Mortgage Bonds Outstanding on the date such policy goes into effect, and/or (ii) co-insurance or self insurance provisions with a dollar amount per occurrence not exceeding thirty percentum (30%) of the loss proceeds otherwise payable; provided, however, that the dollar amount described in clause (i) above may be exceeded to the extent such dollar amount per occurrence is below the deductible amount in effect as to fire insurance (X) on property of similar character insured by companies similarly situated and operating like property or (Y) on property as to which an equal primary fire insurance rate has been set by reputable insurance companies.

(b) All moneys paid to the Trustee by the Company in accordance with this Section or received by the Trustee as proceeds of any insurance, in either case on account of a loss on or with respect to Funded Property, shall, subject to the requirements of the SPPC 1940 Mortgage or other Lien prior hereto upon property subject to the Lien hereof, be held by the Trustee and, subject as aforesaid, shall be paid by it to the Company to reimburse the Company for an equal amount expended or committed for expenditure in the rebuilding, renewal and/or replacement of or substitution for the property destroyed or damaged or lost, upon receipt by the Trustee of:

(i) a Company Request requesting such payment,

(ii) an Expert's Certificate:

(A) describing the property so damaged or destroyed or otherwise lost;

(B) stating the Cost of such property (or, if the Fair Value to the Company of such property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so

53

certified, in lieu of Cost) or, if such damage or destruction shall have affected only a portion of such property, stating the allocable portion of such Cost or Fair Value;

(C) stating the amounts so expended or committed for expenditure in the rebuilding, renewal, replacement of and/or substitution for such property; and

(D) stating the Fair Value to the Company of such property as rebuilt or renewed or as to be rebuilt or renewed and/or of the replacement or substituted property, and if

(II) the Fair Value to the Company of such property as set forth in such Expert's Certificate is not less than Twenty-five Thousand Dollars ($25,000) and not less than one percentum (1%) of the aggregate principal amount of the Securities at the time Outstanding,

the Expert making the statement required by this clause (D) shall be an Independent Expert, and

(iii) an Opinion of Counsel stating that, in the opinion of the signer, the property so rebuilt or renewed or to be rebuilt or renewed, and/or the replacement property, is or will be subject to the Lien hereof to the same extent as was the property so destroyed or damaged or otherwise lost.

Section 1.03, is not less than zero (0) or (II) that the amount of such loss does not exceed the aggregate Cost or Fair Value to the Company (whichever is less) of Property Additions acquired, made or constructed on or after the ninetieth (90th) day prior to the date of the Company Request requesting such payment; or

61

Lien upon all other property, if any, purporting to be subject thereto, subject to no Lien prior thereto except Liens generally of the character of Permitted Liens and Liens permitted to exist or to be hereafter created under Section 6.06 and (B) that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder except on the basis of property generally of the character of Property Additions, the retirement or deposit of outstanding obligations, the deposit of prior Lien obligations or the deposit of cash.

Anything herein to the contrary notwithstanding (a) the aggregate principal amount of obligations secured by Purchase Money Lien which may be used pursuant to subclause (i) and/or subclause (iv) of clause (d) in the first paragraph of this Section as the basis for the release of property from the Lien of this Indenture shall not exceed seventy-five percentum (75%) of the Fair Value of the property to be released, as certified pursuant to clause (c)(ii) in the first paragraph of this Section, and (b) no obligations secured by Purchase Money Lien shall be used as the basis for the release of property hereunder, if the aggregate principal amount of such obligations to be used by the Company pursuant to subclause (i) and/or subclause (iv) of such clause (d) plus the aggregate principal amount used by the Company pursuant to said subclause (i) and subclause (iv) in connection with all previous releases of property from the Lien hereof on the basis of obligations secured by Purchase Money Lien theretofore delivered to and then held by the Trustee or the trustee or other holder of a Lien prior to the Lien of this Indenture shall, immediately after the release then being applied for, exceed forty percentum (40%) of the sum of
(1) the aggregate principal amount of Securities then Outstanding and (2) the aggregate principal amount of First Mortgage Bonds then Outstanding; provided, however, that the limitation set forth in clause (a) above shall not be applicable if no additional obligations are then outstanding, or are permitted to be issued, under the Purchase Money Lien securing such obligations; and provided, further, that there shall not be taken into account for purposes of the calculation contemplated in clause (b) above any obligations secured by Purchase Money Lien with respect to which there shall have been delivered to the Trustee:

(x) an Officer's Certificate (i) if any obligations shall then be outstanding under such Purchase Money Lien and/or additional obligations are permitted to be issued thereunder, either (A) stating that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder on the basis of property additions in a principal amount exceeding seventy percentum (70%) of the balance of the cost or fair value of such property additions to the issuer thereof (whichever shall be less) after making deductions and additions similar to those provided for in Section 1.03, or (B) in the event that the statements contained in clause (A) above cannot be made, stating that such issuer has irrevocably waived its right to the authentication and delivery of obligations under such Purchase Money Lien (1) on any basis, in a principal amount equal to the excess of (I) the aggregate principal amount of obligations, if any, then outstanding under such Purchase Money Lien which were issued on the basis of property additions or on the basis of the retirement of obligations which were issued (whether directly or indirectly when considered in light of the successive issuance and retirement of obligations) on the basis of property additions over (II) an amount equal to seventy percentum (70%) of the aggregate Dollar amount of property additions certified as the basis for the issuance of such obligations then outstanding and (2) on the basis of property additions, in a principal amount exceeding seventy percentum

62

(y) an Opinion or Opinions of Counsel to the effect that (i) if any obligations shall then be outstanding under such Purchase Money Lien and/or additional obligations are permitted to be issued thereunder, to the effect either (A) that the terms of such Purchase Money Lien, as then in effect, do not permit the issuance of obligations thereunder upon the basis of property additions in a principal amount exceeding seventy percentum (70%) of the balance of the cost or the fair value thereof to the issuer of such obligations (whichever shall be less) after making deductions and additions similar to those provided for in Section 1.03, or, if such is not the case, (B) that the waivers contemplated by clause
(x)(i)(B) above have been duly made and (ii) to the effect either (A) that the obligations secured by such Purchase Money Lien delivered to the Trustee or to the trustee or other holder of a Lien prior to the Lien of this Indenture as the basis for such release of property contain a provision for mandatory redemption upon an acceleration) of the maturity of all Outstanding Securities following an Event of Default (whether or not such redemption may be rescinded upon the rescission of such acceleration) or (B) that, so long as such obligations are held by the Trustee or the trustee or other holder of such a prior Lien, an Event of Default under this Indenture constitutes a matured event of default under such Purchase Money Lien (provided, however, that the waiver or cure of such Event of Default hereunder and the rescission and annulment of the consequences thereof may constitute a cure of the corresponding event of default under such Purchase Money Lien and a rescission and annulment of the consequences thereof).

If (a) any property to be released from the Lien of this Indenture under any provision of this Article (other than Section 8.07) is subject to a Lien prior to the Lien hereof and is to be sold, exchanged, dedicated or otherwise disposed of subject to such prior Lien and (b) after such release, such prior Lien will not be a Lien on any property subject to the Lien hereof, then the Fair Value of such property to be released shall be deemed, for all purposes of this Indenture, to be the value thereof unencumbered by such prior Lien less the principal amount of the indebtedness secured by such prior Lien.

Any Outstanding Securities delivered to the Trustee pursuant to clause (d) in the first paragraph of this Section shall forthwith be canceled by the Trustee. Any cash and/or

63

obligations so deposited with the Trustee, and the proceeds of any such obligations, shall be held as part of the Mortgaged Property and shall be withdrawn, released, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

In such event, (a) the application of Property Additions in the release under this
Section 8.03 as contemplated in clause (d)(ii) in the first paragraph thereof shall be taken into account in clause (v) or clause (vi), whichever may be applicable, of the Expert's Certificate described in clause (c) in Section 8.04 and (b) the Trustee shall, at the election of the Company, execute and deliver a separate instrument of release with respect to the property released under each of such Sections or a consolidated instrument of release with respect to the property released under both of such Sections considered as a whole.

Section in such calendar year and, as to Funded Property, the Cost thereof (or, if the Fair Value to the Company of such property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost), and that, in the judgment of the signers, the release thereof will not impair the security under this Indenture in contravention of the provisions hereof. On or before December 31st of each calendar year, the Company shall deposit with the Trustee an amount in cash equal to seventy percentum (70%) of the aggregate Cost of the properties constituting Funded Property so released during such year (or, if the Fair Value to the Company of any particular property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost); provided, however, that no such deposit shall be required to be made hereunder to the extent that cash or other consideration shall, as indicated in an Officer's Certificate delivered to the Trustee, have been deposited with the trustee or other holder of the SPPC 1940 Mortgage or other Lien prior to the Lien of this Indenture in accordance with the provisions thereof; and provided, further, that the amount of cash so required to be deposited may be reduced, at the election of the Company, by the items specified in clause (d) in the first paragraph of Section 8.03, subject to all of the limitations and conditions specified in such Section, to the same extent as if such property were being released pursuant to Section 8.03. Any cash deposited with the Trustee under this Section may thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

SECTION 8.06 Withdrawal or Other Application of Funded Cash; Purchase Money Obligations.

Subject to the provisions of Section 4.04 and except as hereafter in this Section provided, unless an Event of Default shall have occurred and be continuing, any Funded Cash held by the Trustee, and any other cash which is required to be withdrawn, used or applied as provided in this Section,

(a) may be withdrawn from time to time by the Company to the extent of an amount equal to seventy percentum (70%) of the Cost or the Fair Value to the Company (whichever is less) of Property Additions not constituting Funded Property, after making any deductions and additions pursuant to Section 1.03, described in an Expert's Certificate, dated not more than ninety (90) days prior to the date of the Company Order requesting such withdrawal and complying with clause (ii) and, to the extent applicable, clause (iii) in Section 4.02(b), delivered to the Trustee; provided, however, that the deductions and additions contemplated by Section 1.03 shall not be required to be made if such Property Additions were acquired, made or constructed on or after the ninetieth (90th) day preceding the date of such Company Order;

(b) may be withdrawn from time to time by the Company in an amount equal to the aggregate principal amount of Securities to the authentication and delivery of which the Company shall be entitled under the provisions of Section 4.03 hereof, by virtue of compliance with all applicable provisions of Section
4.03 (except as hereinafter in this Section otherwise provided); provided, however, that such withdrawal of cash shall operate as a waiver by the Company of the right to the authentication and delivery of such Securities and, to such extent, no such Securities may thereafter be authenticated and delivered hereunder; and any such Securities

66

which were the basis of such right to the authentication and delivery of Securities so waived shall be deemed to have been made the basis of such withdrawal of cash;

(c) may be withdrawn from time to time by the Company in an amount equal to the aggregate principal amount of any Outstanding Securities delivered to the Trustee;

(d) may, upon the request of the Company, be used by the Trustee for the purchase of Securities in the manner, at the time or times, in the amount or amounts, at the price or prices and otherwise as directed or approved by the Company, all subject to the limitations hereafter in this Section set forth; or

(e) may, upon the request of the Company, be applied by the Trustee to the payment (or provision therefor pursuant to Article IX) at Stated Maturity of any Securities or to the redemption (or similar provision therefor) of any Securities which are, by their terms, redeemable, in each case of such series as may be designated by the Company, any such redemption to be in the manner and as provided in Article V, all subject to the limitations hereafter in this Section set forth.

Such moneys shall, from time to time, be paid or used or applied by the Trustee, as aforesaid, upon the request of the Company in a Company Order, and upon receipt by the Trustee of an Officer's Certificate stating that, to the knowledge of the signer, no Event of Default has occurred and is continuing. If and to the extent that the withdrawal of cash is based upon Property Additions (as permitted under the provisions of clause (a) above), the Company shall, subject to the provisions of said clause (a) and except as hereafter in this paragraph provided, comply with all applicable provisions of this Indenture as if such Property Additions were made the basis for the authentication and delivery of Securities equal in principal amount to the cash so to be withdrawn. If and to the extent that the withdrawal of cash is based upon the right to the authentication and delivery of Securities (as permitted under the provisions of clause (b) above), the Company shall, except as hereafter in this paragraph provided, comply with all applicable provisions of Section 4.03 relating to such authentication and delivery. Notwithstanding the foregoing provisions of this paragraph, in no event shall the Company be required to deliver the documents specified in Section 4.01.

Notwithstanding the generality of clauses (d) and (e) above, no cash to be applied pursuant to such clauses shall be applied to the payment of an amount in excess of the principal amount of any Securities to be purchased, paid or redeemed except to the extent that the aggregate principal amount of all Securities theretofore, and of all Securities then to be, purchased, paid or redeemed pursuant to such clauses is not less than the aggregate cost for principal of, premium, if any, and accrued interest, if any, on and brokerage commissions, if any, with respect to, such Securities.

Any Outstanding Securities delivered to the Trustee pursuant to clause (c) in the first paragraph of this Section shall forthwith be canceled by the Trustee.

Any obligations secured by Purchase Money Lien delivered to the Trustee in consideration of the release of property from the Lien of this Indenture, together with any evidence of such Purchase Money Lien held by the Trustee, shall be released from the Lien of

67

this Indenture and delivered to or upon the order of the Company upon payment by the Company to the Trustee of an amount in cash equal to the aggregate principal amount of such obligations less the aggregate amount theretofore paid to the Trustee (by the Company, the obligor or otherwise) in respect of the principal of such obligations.

The principal of and interest on any such obligations secured by Purchase Money Lien held by the Trustee shall be held by the Trustee as and when the same are received by the Trustee. The interest received by the Trustee on any such obligations shall be deemed not to constitute Funded Cash and shall be remitted to the Company; provided, however, that if an Event of Default shall have occurred and be continuing, such proceeds shall be held as part of the Mortgaged Property until such Event of Default shall have been cured or waived.

The Trustee shall have and may exercise all the rights and powers of any owner of such obligations and of all substitutions therefor and, without limiting the generality of the foregoing, may collect and receive all insurance moneys payable to it under any of the provisions thereof and apply the same in accordance with the provisions thereof, may consent to extensions thereof at a higher or lower rate of interest, may join in any plan or plans of voluntary or involuntary reorganization or readjustment or rearrangement and may accept and hold hereunder new obligations, stocks or other securities issued in exchange therefor under any such plan. Any discretionary action which the Trustee may be entitled to take in connection with any such obligations or substitutions therefor shall be taken, so long as no Event of Default shall have occurred and be continuing, in accordance with a Company Order, and, during the continuance of an Event of Default, in its own discretion.

Anything herein to the contrary notwithstanding, the Company may irrevocably waive all right to the withdrawal pursuant to this Section of, and any other rights with respect to, any obligations secured by Purchase Money Lien held by the Trustee, and the proceeds of any such obligations, by delivery to the Trustee of a Company Order:

(a) specifying such obligations and stating that the Company thereby waives all rights to the withdrawal thereof and of the proceeds thereof pursuant to this Section, and any other rights with respect thereto; and

(b) directing that the principal of such obligations be applied as provided in clause (e) in the first paragraph of this Section, specifying the Securities to be paid or redeemed or for the payment or redemption of which payment is to be made.

Following any such waiver, the interest on any such obligations shall be applied to the payment of interest, if any, on the Securities to be paid or redeemed or for the payment or redemption of which provision is to be made, as specified in the aforesaid Company Order, as and when such interest shall become due from time to time, and any excess funds remaining from time to time after such application shall be applied to the payment of interest on any other Securities as and when the same shall become due. Pending any such application, the interest on such obligations shall be invested in Investment Securities. The principal of any such obligations shall be applied solely to the payment of principal of the Securities to be paid or redeemed or for the payment or redemption of which provision is to be made, as specified in the aforesaid Company Order. Pending such application, the principal of such obligations shall be invested in Eligible

68

Obligations. The obligation of the Company to pay the principal of such Securities when the same shall become due at maturity, shall be offset and reduced by the amount of the proceeds of such obligations then held, and to be applied, by the Trustee in accordance with this paragraph.

SECTION 8.07 Release of Property Taken by Eminent Domain, etc.

Should any of the Mortgaged Property, or any interest therein, be taken by exercise of the power of eminent domain or be sold to an entity possessing the power of eminent domain under a threat to exercise the same, and should the Company elect not to obtain the release of such property pursuant to other provisions of this Article, the Trustee shall, upon request of the Company evidenced by a Company Order transmitting therewith a form of instrument to effect such release, release from the Lien hereof all its right, title and interest in and to the property so taken or sold (or with respect to an interest in property, subordinate the Lien hereof to such interest), upon receiving (a) an Opinion of Counsel to the effect that such property has been taken by exercise of the power of eminent domain or has been sold to an entity possessing the power of eminent domain under threat of an exercise of such power, (b) an Officer's Certificate stating the amount of net proceeds received or to be received for such property so taken or sold, and the amount so stated shall be deemed to be the Fair Value of such property for the purpose of any notice to the Holders of Securities, (c) if any portion of such property constitutes Funded Property, an Expert's Certificate stating the Cost thereof (or, if the Fair Value to the Company of such portion of such property at the time the same became Funded Property was certified to be an amount less than the Cost thereof, then such Fair Value, as so certified, in lieu of Cost) and (d) if any portion of such property constitutes Funded Property, a deposit by the Company of an amount in cash equal to seventy percentum (70%) of the Cost or Fair Value stated in the Expert's Certificate delivered pursuant to clause (c) above; provided, however, that the amount required to be so deposited shall not exceed the portion of the net proceeds received or to be received for such property so taken or sold which is allocable on a pro-rata or other reasonable basis to the portion of such property constituting Funded Property; and provided, further, that no such deposit shall be required to be made hereunder if the proceeds of such taking or sale shall, as indicated in an Officer's Certificate delivered to the Trustee, have been deposited with the trustee or other holder of the SPPC 1940 Mortgage or other Lien prior to the Lien of this Indenture. Any cash deposited with the Trustee under this Section may thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 8.06.

SECTION 8.08 Disclaimer or Quitclaim.

In case the Company has sold, exchanged, dedicated or otherwise disposed of, or has agreed or intends to sell, exchange, dedicate or otherwise dispose of, or a Governmental Authority has ordered the Company to divest itself of, any Excepted Property or any other property not subject to the Lien hereof, or the Company desires to disclaim or quitclaim title to property to which the Company does not purport to have title, the Trustee shall, from time to time, disclaim or quitclaim such property upon receipt by the Trustee of the following:

(a) a Company Order requesting such disclaimer or quitclaim and transmitting therewith a form of instrument to effect such disclaimer or quitclaim;

69

(b) an Officer's Certificate describing the property to be disclaimed or quitclaimed; and

(c) an Opinion of Counsel stating the signer's opinion that such property is not subject to the Lien hereof or required to be subject thereto by any of the provisions hereof.

SECTION 8.09 Miscellaneous.

(a) The Expert's Certificate as to the Fair Value of property to be released from the Lien of this Indenture in accordance with any provision of this Article, and as to the nonimpairment, by reason of such release, of the security under this Indenture in contravention of the provisions hereof, shall be made by an Independent Expert if the Fair Value of such property and of all other property released since the commencement of the then current calendar year, as set forth in the certificates required by this Indenture, is ten percentum (10%) or more of the aggregate principal amount of the Securities at the time Outstanding; but such Expert's Certificate shall not be required to be made by an Independent Expert in the case of any release of property if the Fair Value thereof, as set forth in the certificates required by this Indenture, is less than Twenty-five Thousand Dollars ($25,000) or less than one percentum (1%) of the aggregate principal amount of the Securities at the time Outstanding. To the extent that the Fair Value of any property to be released from the Lien of this Indenture shall be stated in an Independent Expert's Certificate, such Fair Value shall not be required to be stated in any other Expert's Certificate delivered in connection with such release.

(b) No release of property from the Lien of this Indenture effected in accordance with the provisions, and in compliance with the conditions, set forth in this Article and in Sections 1.04 and 1.05 shall be deemed to impair the security of this Indenture in contravention of any provision hereof.

(c) If the Mortgaged Property shall be in the possession of a receiver or trustee, lawfully appointed, the powers hereinbefore conferred upon the Company with respect to the release of any part of the Mortgaged Property or any interest therein or the withdrawal of cash may be exercised, with the approval of the Trustee, by such receiver or trustee, notwithstanding that an Event of Default may have occurred and be continuing, and any request, certificate, appointment or approval made or signed by such receiver or trustee for such purposes shall be as effective as if made by the Company or any of its officers or appointees in the manner herein provided; and if the Trustee shall be in possession of the Mortgaged Property under any provision of this Indenture, then such powers may be exercised by the Trustee in its discretion notwithstanding that an Event of Default may have occurred and be continuing.

(d) If the Company shall retain any interest in any property released from the Lien of this Indenture as provided in Section 8.03, 8.04 or 8.05, this Indenture shall not become or be, or be required to become or be, a Lien upon such property or such interest therein or any improvements, extensions or additions to such property or renewals, replacements or substitutions of or for such property or any part or parts thereof unless the Company shall execute and deliver to the Trustee an indenture supplemental hereto, in recordable form, containing a grant, conveyance, transfer and mortgage thereof. As used in this subsection, the

70

terms "improvements", "extensions" and "additions" shall be limited as set forth in Section 13.01.

(e) Notwithstanding the occurrence and continuance of an Event of Default, the Trustee, in its discretion, may release from the Lien hereof any part of the Mortgaged Property or permit the withdrawal of cash, upon compliance with the other conditions specified in this Article in respect thereof.

(f) No purchaser or grantee of property purporting to have been released hereunder shall be bound to ascertain the authority of the Trustee to execute the release, or to inquire as to any facts required by the provisions hereof for the exercise of such authority; nor shall any purchaser or grantee of any property or rights permitted by this Article to be sold, granted, exchanged, dedicated or otherwise disposed of, be under obligation to ascertain or inquire into the authority of the Company to make any such sale, grant, exchange, dedication or other disposition.

ARTICLE IX

SATISFACTION AND DISCHARGE

SECTION 9.01 Satisfaction and Discharge of Securities.

Any Security or Securities, or any portion of the principal amount thereof, shall be deemed to have been paid for all purposes of this Indenture, and the entire indebtedness of the Company in respect thereof shall be satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust:

(a) money (including Funded Cash not otherwise applied pursuant to
Section 8.06) in an amount which shall be sufficient, or

(b) in the case of a deposit made prior to the Maturity of such Securities or portions thereof, Eligible Obligations, which shall not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee or such Paying Agent, shall be sufficient, or

(c) a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof; provided, however, that in the case of the provision for payment or redemption of less than all the Securities of any series or Tranche, such Securities or portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such redemption shall have been given or irrevocable authority shall have been given by the Company to the Trustee to give such notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the Trustee and such Paying Agent:

71

(x) if such deposit shall have been made prior to the Maturity of such Securities, a Company Order stating that the money and Eligible Obligations deposited in accordance with this Section shall be held in trust, as provided in Section 9.03;

(y) if Eligible Obligations shall have been deposited, an Opinion of Counsel to the effect that such obligations constitute Eligible Obligations and do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, and an opinion of an Independent public Accountant of nationally recognized standing, selected by the Company, to the effect that the other requirements set forth in clause (b) above have been satisfied; and

(z) if such deposit shall have been made prior to the Maturity of such Securities, an Officer's Certificate stating the Company's intention that, upon delivery of such Officer's Certificate, its indebtedness in respect of such Securities or portions thereof will have been satisfied and discharged as contemplated in this Section.

Upon the deposit of money or Eligible Obligations, or both, in accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon Company Request, acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof has been satisfied and discharged as contemplated in this Section. In the event that all of the conditions set forth in the preceding paragraph shall have been satisfied in respect of any Securities or portions thereof except that, for any reason, the Officer's Certificate specified in clause (z) (if otherwise required) shall not have been delivered, such Securities or portions thereof shall nevertheless be deemed to have been paid for all purposes of this Indenture, and the Holders of such Securities or portions thereof shall nevertheless be no longer entitled to the benefit of the Lien of this Indenture or of any of the covenants of the Company under Article VI (except the covenants contained in Sections 6.02 and 6.03) or any other covenants made in respect of such Securities or portions thereof as contemplated by Section 3.01, but the indebtedness of the Company in respect of such Securities or portions thereof shall not be deemed to have been satisfied and discharged prior to Maturity for any other purpose; and, upon Company Request, the Trustee shall acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture.

If payment at Stated Maturity of less than all of the Securities of any series, or any Tranche thereof, is to be provided for in the manner and with the effect provided in this Section, the Security Registrar shall select such Securities, or portions of principal amount thereof, in the manner specified by
Section 5.03 for selection for redemption of less than all the Securities of a series or Tranche.

In the event that Securities which shall be deemed to have been paid for purposes of this Indenture, and, if such is the case, in respect of which the Company's indebtedness shall have been satisfied and discharged, all as provided in this Section, do not mature and are not to be redeemed within the sixty (60) day period commencing with the date of the deposit of moneys or Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a

72

notice, in the same manner as a notice of redemption with respect to such Securities, to the Holders of such Securities to the effect that such deposit has been made and the effect thereof.

Notwithstanding that any Securities shall be deemed to have been paid for purposes of this Indenture, as aforesaid, the obligations of the Company and the Trustee in respect of such Securities under Sections 3.04, 3.05, 3.06, 5.04, 6.02, 6.03, 11.07 and 11.15 and this Article shall survive.

The Company shall pay, and shall indemnify the Trustee or any Paying Agent with which Eligible Obligations shall have been deposited as provided in this Section against, any tax, fee or other charge imposed on or assessed against such Eligible Obligations or the principal or interest received in respect of such Eligible Obligations, including, but not limited to, any such tax payable by any entity deemed, for tax purposes, to have been created as a result of such deposit.

Anything herein to the contrary notwithstanding, (a) if, at any time after a Security would be deemed to have been paid for purposes of this Indenture, and, if such is the case, the Company's indebtedness in respect thereof would be deemed to have been satisfied and discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or any Paying Agent, as the case may be, shall be required to return the money or Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable Federal or State bankruptcy, insolvency or other similar law, such Security shall thereupon be deemed retroactively not to have been paid and any satisfaction and discharge of the Company's indebtedness in respect thereof shall retroactively be deemed not to have been effected, and such Security shall be deemed to remain Outstanding and (b) any satisfaction and discharge of the Company's indebtedness in respect of any Security shall be subject to the provisions of the last paragraph of
Section 6.03.

SECTION 9.02 Satisfaction and Discharge of Indenture.

This Indenture shall upon Company Request cease to be of further effect (except as hereinafter expressly provided), and the Trustee, at the expense of the Company, shall execute such instruments as the Company shall reasonably request to evidence and acknowledge the satisfaction and discharge of this Indenture, when:

(a) no Securities remain Outstanding hereunder; and

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company;

provided, however, that if, in accordance with the last paragraph of Section 9.01, any Security, previously deemed to have been paid for purposes of this Indenture, shall be deemed retroactively not to have been so paid, this Indenture shall thereupon be deemed retroactively not to have been satisfied and discharged, as aforesaid, and to remain in full force and effect, and the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same.

73

Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the Trustee under Sections 3.04, 3.05, 3.06, 5.04, 6.02, 6.03, 11.07 and 11.15 and this Article shall survive.

Upon satisfaction and discharge of this Indenture as provided in this Section, the Trustee shall release, quit claim and otherwise turn over to the Company the Mortgaged Property (other than money and Eligible Obligations held by the Trustee pursuant to Section 9.03) and shall execute and deliver to the Company such deeds and other instruments as, in the judgment of the Company, shall be necessary, desirable or appropriate to effect or evidence such release and quitclaim and the satisfaction and discharge of this Indenture.

SECTION 9.03 Application of Trust Money.

Neither the Eligible Obligations nor the money deposited pursuant to
Section 9.01, nor the principal or interest payments on any such Eligible Obligations, shall be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Securities or portions of principal amount thereof in respect of which such deposit was made, all subject, however, to the provisions of Section 6.03; provided, however, that any cash received from such principal or interest payments on such Eligible Obligations, if not then needed for such purpose, shall, to the extent practicable and upon Company Request and delivery to the Trustee of the documents referred to in clause (y) in the first paragraph of Section 9.01, be invested in Eligible Obligations of the type described in clause (b) in the first paragraph of Section 9.01 maturing at such times and in such amounts as shall be sufficient, together with any other moneys and the proceeds of any other Eligible Obligations then held by the Trustee, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on and prior to the Maturity thereof, and interest earned from such reinvestment shall be paid over to the Company as received, free and clear of the Lien of this Indenture, except the Lien provided by Section 11.07; and provided, further, that any moneys held in accordance with this Section on the Maturity of all such Securities in excess of the amount required to pay the principal of and premium, if any, and interest, if any, then due on such Securities shall be paid over to the Company free and clear of the Lien of this Indenture, except the Lien provided by Section 11.07; and provided, further, that if an Event of Default shall have occurred and be continuing, moneys to be paid over to the Company pursuant to this Section shall be held as part of the Mortgaged Property until such Event of Default shall have been waived or cured.

ARTICLE X

(d) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding up or liquidation of its affairs, and any such decree or order for relief or any such other decree or order shall have remained unstayed and in effect for a period of ninety (90) consecutive days; or

75

that, anything in this Indenture to the contrary notwithstanding, the waiver or cure of such event of default under the SPPC 1940 Mortgage and the rescission and annulment of the consequences thereof under the SPPC 1940 Mortgage shall constitute a cure of the corresponding Event of Default hereunder and a rescission and annulment of the consequences thereof.

SECTION 10.02 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default shall have occurred and be continuing, then in every such case the Trustee or the Holders of not less than thirty-three percentum (33%) in principal amount of the Securities then Outstanding may declare the principal amount (or, if any of the Securities are Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof as contemplated by Section 3.01) of all Securities then Outstanding to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon such declaration such principal amount (or specified amount), together with premium, if any, and accrued interest, if any, thereon, shall become immediately due and payable, all subject, however, in the case of an Event of Default described in clause (f) of Section 10.01, to the proviso contained in such clause (f).

At any time after such a declaration of acceleration of the maturity of the Securities then Outstanding shall have been made, but before any sale of any of the Mortgaged Property has been made and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as provided in this Article, the Event or Events of Default giving rise to such declaration of acceleration shall, without further act, be deemed to have been cured, and such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled, if

(a) the Company shall have paid or deposited with the Trustee a sum sufficient to pay

(i) all overdue interest, if any, on all Securities then Outstanding;

(ii) the principal of and premium, if any, on any Securities then Outstanding which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities; and

(b) any other Event or Events of Default, other than the non-payment of the principal of Securities which shall have become due solely by such declaration of acceleration, shall have been cured or waived as provided in
Section 10.17.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereon.

76

If an Event of Default described in clause (a) or (b) of Section 10.01 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Securities with respect to which such Event of Default shall have

78

occurred, the whole amount then due and payable on such Securities for principal and premium, if any, and interest, if any, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 11.07.

If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

No recovery of any such judgment by the Trustee and no levy of any execution upon any such judgment upon any of the Mortgaged Property or any other property of the Company shall affect or impair the Lien of this Indenture upon the Mortgaged Property or any part thereof or any rights, powers or remedies of the Trustee hereunder, or any rights, powers or remedies of the Holders of the Securities.

(a) to file and prove a claim for the whole amount of principal, premium, if any, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for amounts due to the Trustee under Section 11.07) and of the Holders allowed in such judicial proceeding, and

All rights of action and claims under this Indenture or on the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

SECTION 10.11 Limitation on Suits.

No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

SECTION 10.13 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holder shall continue as though no such proceeding had been instituted.

SECTION 10.14 Rights and Remedies Cumulative.

Except as otherwise provided in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Anything in this Article to the contrary notwithstanding, the availability of the remedies set forth herein (on an individual or cumulative basis) and the procedures set forth herein relating to the exercise thereof shall be subject to (a) the law (including, for purposes of this paragraph, general principles of equity) of any jurisdiction wherein the Mortgaged Property or any part thereof is located to the extent that such law is mandatorily applicable and (b) the rights of the holder of any Lien prior to the Lien of this Indenture, and, if and to the extent that any provision of this Article conflicts with any provision of such applicable law and/or with the rights of the holder of any such prior Lien, such provision of law and/or the rights of such holder shall control.

SECTION 10.15 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

If an Event of Default shall have occurred and be continuing, the Holders of a majority in principal amount of the Securities then Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee; provided, however, that

(a) such direction shall not be in conflict with any rule of law or with this Indenture, and could not involve the Trustee in personal liability in circumstances where indemnity would not, in the Trustee's sole discretion, be adequate, and

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 10.17 Waiver of Past Defaults.

Before any sale of any of the Mortgaged Property and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as in this Article provided, the Holders of not less than a majority in principal amount of the Securities then Outstanding may on behalf of the Holders of all the Securities then Outstanding waive any past default hereunder and its consequences, except a default

(a) in the payment of the principal of or premium, if any, or interest, if any, on any Security Outstanding, or

(b) in respect of a covenant or provision hereof which under Section 14.02 cannot be modified or amended without the consent of the Holder of each Outstanding Security of any series or Tranche affected.

Upon any such waiver, such default shall cease to exist, and any and all Events of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 10.18 Undertaking for Costs.

The Company and the Trustee agree, and each Holder of Securities by its acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than ten percentum (10%) in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest, if any, on any Security on or after

83

the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

SECTION 10.19 Waiver of Appraisement and Other Laws.

To the full extent that it may lawfully so agree, the Company shall not at any time set up, claim or otherwise seek to take the benefit or advantage of any appraisement, valuation, stay, extension or redemption law, now or hereafter in effect, in order to prevent or hinder the enforcement of this Indenture or the absolute sale of the Mortgaged Property, or any part thereof, or the possession thereof, or any part thereof, by any purchaser at any sale under this Article; and the Company, for itself and all who may claim under it, so far as it or they now or hereafter may lawfully do so, hereby waives the benefit of all such laws. The Company, for itself and all who may claim under it, waives, to the extent that it may lawfully do so, all right to have the Mortgaged Property marshalled upon any foreclosure of the Lien hereof, and agrees that any court having jurisdiction to foreclose the Lien of this Indenture may order the sale of the Mortgaged Property as an entirety.

(ii) the Trustee shall cease to be eligible under Section 11.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (x) the Company by a Board Resolution may remove the Trustee or (y) subject to Section 10.18, any Holder who has been a bona fide Holder for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee or Trustees.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause (other than as contemplated in clause (y) in subsection (d) of this Section), the Company, by a Board Resolution, shall take prompt steps to appoint a successor Trustee or Trustees and shall comply with the applicable requirements of Section 11.11. If, within one (1) year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Securities then Outstanding delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 11.11, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by
Section 11.11, any Holder who has been a bona fide Holder of a Security for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) So long as no event which is, or after notice or lapse of time, or both, would become, an Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee (i) a Board Resolution appointing a successor Trustee, effective as of a date specified therein, and (ii) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with Section 11.11, the Trustee shall be deemed to have resigned as contemplated in subsection (b) of this Section, the successor Trustee shall be deemed to have been appointed pursuant to subsection (e) of this Section and such appointment shall be deemed to have been accepted as contemplated in Section 11.11, all as of such date, and all other provisions of this Section and Section 11.11 shall be applicable to such resignation, appointment and acceptance except to the extent inconsistent with this subsection (f).

90

(g) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee and the address of its corporate trust office.

SECTION 11.11 Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all sums owed to it, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its Lien provided for in Section 11.07.

(b) Upon request of any such successor Trustee, the Company shall execute any instruments which fully vest in and confirm to such successor Trustee all rights, powers and trusts referred to in subsection (a) of this Section.

SECTION 11.12 Merger, Conversion, Consolidation or Succession to Business.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 11.13 Preferential Collection of Claims against Company.

If the Trustee shall be or become a creditor of the Company or any other obligor upon the Securities (other than by reason of a relationship described in Section 311(b) of the Trust Indenture Act), the Trustee shall be subject to any and all applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company or such other obligor. For purposes of Section 3.11(b) of the Trust Indenture Act:

(A) the term "cash transaction" means any transaction in

(B) the term "self-liquidating paper" means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company or such obligor for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company or such obligor arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation.

SECTION 11.14 Co-trustees and Separate Trustees.

At any time or times, for the purpose of meeting the legal requirements of any jurisdiction in which any of the Mortgaged Property may at the time be located, the Company and the Trustee shall have power to appoint, and, upon the written request of the Trustee or of the Holders of at least thirty-three percentum (33%) in principal amount of the Securities then Outstanding, the Company shall for such purpose join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee and, if no Event of Default shall have occurred and be continuing, by the Company either to act as co-trustee, jointly with the Trustee, of all or any part of the Mortgaged Property, or to act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons, in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Company does not join in such appointment within fifteen
(15) days after the receipt by it of a request so to do, or if an Event of Default shall have occurred and be continuing, the Trustee alone shall have power to make such appointment.

Should any written instrument or instruments from the Company be required by any co-trustee or separate trustee so appointed to more fully confirm to such co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company.

Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following conditions:

(A) the Securities shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the Trustee;

92

(B) the rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed either by the Trustee or by the Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee;

(C) the Trustee at any time, by an instrument in writing executed by it, with the concurrence of the Company, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, if an Event of Default shall have occurred and be continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section;

(D) neither the Trustee nor any co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(E) any Act of Holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee.

SECTION 11.15 Appointment of Authenticating Agent.

The Trustee may appoint an Authenticating Agent or Agents with respect to the Securities of one or more series, or any Tranche thereof, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series or Tranche issued upon original issuance, exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any State or Territory thereof or the District of Columbia or the Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than Fifty Million Dollars ($50,000,000) and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to

93

the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

The provisions of Sections 3.08, 11.04 and 11.05 shall be applicable to each Authenticating Agent.

If an appointment with respect to the Securities of one or more series, or any Tranche thereof, shall be made pursuant to this Section, the Securities of such series or Tranche may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication substantially in the following form:

94

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

THE BANK OF NEW YORK, as Trustee

By
As Authenticating Agent

By
Authorized Officer

If all of the Securities of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 1.04 and need not be accompanied by an Opinion of Counsel), shall appoint, in accordance with this Section and in accordance with such procedures as shall be acceptable to the Trustee, an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

100

any Holders, enter into an indenture supplemental hereto to amend this Indenture to effect such changes or elimination.

SECTION 14.02 Supplemental Indentures with Consent of Holders.

Subject to the provisions of Section 14.01, 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 this Indenture, considered as one class, by Act of said Holders delivered to the Company and the Trustee, the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture; provided, however, that if there shall be Securities of more than one series Outstanding hereunder 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 a 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 no such supplemental indenture shall:

SECTION 14.03 Execution of Supplemental Indentures.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 11.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties, immunities or liabilities under this Indenture or otherwise.

SECTION 14.04 Effect of Supplemental Indentures.

Upon the execution and delivery of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. Any supplemental indenture permitted by this Article may restate this Indenture in its entirety, and, upon the execution and delivery thereof, any such restatement shall supersede this Indenture as theretofore in effect for all purposes.

SECTION 14.05 Conformity with Trust Indenture Act.

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

SECTION 14.06 Reference in Securities to Supplemental Indentures.

If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

SECTION 14.07 Modification Without Supplemental Indenture.

To the extent, if any, that the terms of any particular series of Securities shall have been established in or pursuant to a Board Resolution or an Officer's Certificate pursuant to a supplemental indenture or a Board Resolution as contemplated by Section 3.01, and not in a supplemental indenture, additions to, changes in or the elimination of any of such terms may be effected by means of a supplemental Board Resolution or a supplemental Officer's Certificate, as the case may be, delivered to, and accepted by, the Trustee; provided, however, that such supplemental Board Resolution or supplemental Officer's Certificate shall not be accepted by the Trustee or otherwise be effective unless all conditions set forth in this Indenture which would be required to be satisfied if such additions, changes or elimination were contained in a supplemental indenture shall have been appropriately satisfied. Upon the acceptance thereof by the Trustee, any such supplemental Board Resolution or supplemental Officer's Certificate shall be deemed to be a "supplemental indenture" for purposes of Section 14.04 and 14.06 and a "supplemental indenture", "indenture supplemental" to this Indenture or "instrument" supplemental to this Indenture for purposes of Section 6.08.

The Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which a meeting shall have been called as hereinbefore provided, considered as one class, shall constitute a quorum for a meeting of Holders of Securities of such series and Tranches; provided, however, that if any

104

action is to be taken at such meeting which this Indenture expressly provides may be taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, shall constitute a quorum. In the absence of a quorum within one hour of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series and Tranches, be dissolved. In any other case the meeting may be adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such meeting.

Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series and Tranches which shall constitute a quorum.

Except as limited by Section 14.02, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches with respect to which such meeting shall have been called, considered as one class; provided, however, that, except as so limited, any resolution with respect to any action which this Indenture expressly provides may be taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one class.

SECTION 15.05 Attendance at Meetings; Determination of Voting Rights; Conduct and Adjournment of Meetings.

(a) Attendance at meetings of Holders of Securities may be in person or by proxy; and, to the extent permitted by law, any such proxy shall remain in effect and be binding upon any future Holder of the Securities with respect to which it was given unless and until specifically revoked by the Holder or future Holder (except as provided in Section 1.06(g)) of such Securities before being voted.

105

and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations and approved by the Company, the holding of Securities shall be proved in the manner specified in Section 1.06 and the appointment of any proxy shall be proved in the manner specified in Section 1.06. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.06 or other proof.

(c) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 15.02(b), in which case the Company or the Holders of Securities of the series and Tranches calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class.

(d) At any meeting each Holder or proxy shall be entitled to one vote for each One Thousand Dollars ($1,000) principal amount of Outstanding Securities held or represented by such Holder; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security or proxy.

(e) Any meeting duly called pursuant to Section 15.02 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class; and the meeting may be held as so adjourned without further notice.

SECTION 15.06 Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders shall be by written ballots on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities, of the series and Tranches with respect to which the meeting shall have been called, held or represented by them. The permanent chairman of the meeting shall appoint two (2) inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that such notice was given as provided in
Section 15.02 and, if applicable, Section 15.04. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and

106

another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

SECTION 15.07 Action Without Meeting.

In lieu of a vote of Holders at a meeting as hereinbefore contemplated in this Article, any request, demand, authorization, direction, notice, consent, waiver or other action may be made, given or taken by Holders by one or more written instruments as provided in Section 1.05.

EXHIBIT 4.2(c)

SIERRA PACIFIC POWER COMPANY

OFFICER'S CERTIFICATE

I, the undersigned officer of Sierra Pacific Power Company (the "Company"), do hereby certify that I am an Authorized Officer of the Company as such term is defined in the Indenture (as defined herein). I am delivering this certificate pursuant to the authority granted in the Board Resolutions of the Company dated May 22, 2001, and Sections 1.04, 2.01, 3.01 and 4.01(a) of the General and Refunding Mortgage Indenture dated as of May 1, 2001 (the "Mortgage Indenture"), as supplemented by a First Supplemental Indenture dated as of May 1, 2001 (the "Supplemental Indenture"; and collectively with the Mortgage Indenture, the "Indenture"), between the Company and The Bank of New York, as Trustee (the "Trustee"). Terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture unless the context clearly requires otherwise. Based upon the foregoing, I hereby certify on behalf of the Company as follows:

1. The terms and conditions of the Securities described in this Officer's Certificate are as follows (the lettered subdivisions set forth in this Paragraph 1 corresponding to the lettered subdivisions of Section 3.01 of the Mortgage Indenture):

(a) The Securities of the first series to be issued under the Indenture shall be designated "8% General and Refunding Mortgage Bonds, Series A, due 2008" (the "Series A Bonds").

(b) There shall be no limit upon the aggregate principal amount of the Series A Bonds that may be authenticated and delivered under the Indenture. The Series A Bonds shall be initially authenticated and delivered in the aggregate principal amount of $350,000,000.

(c) Interest on the Series A Bonds shall be payable to the Persons in whose names such Securities are registered at the close of business on the Regular Record Date for such interest, except as otherwise expressly provided in the form of such Securities attached hereto as Exhibit A.

(d) The Series A Bonds shall mature and the principal thereof shall be due and payable together with all accrued and unpaid interest thereon on June 1, 2008.

(e) The Series A Bonds shall bear interest at the rate of 8% per annum. Interest shall accrue on the Series A Bonds from May 24, 2001, or the most recent date to which interest has been paid or duly provided for. The Interest Payment Dates for the Series A Bonds shall be June 1 and December 1 in each year commencing December 1, 2001, and the Regular Record Dates with respect to the Interest Payment Dates for the Series A Bonds shall be May 17 and November 16 in each year, respectively (whether or not a Business Day).

(f) The Corporate Trust Office of The Bank of New York in New York, New York shall be the place at which (i) the principal of, premium and interest on, the Series A


Bonds shall be payable, (ii) registration of transfer of the Series A Bonds may be effected, (iii) exchanges of the Series A Bonds may be effected and (iv) notices and demands to or upon the Company in respect of the Series A Bonds and the Indenture may be served; and The Bank of New York shall be the Security Registrar for the Series A Bonds; provided, however, that the Company reserves the right to change, by one or more Officer's Certificates, any such place or the Security Registrar; and provided, further, that the Company reserves the right to designate, by one or more Officer's Certificates, its principal office in Las Vegas, Nevada as any such place or itself as the Security Registrar; provided, however, that there shall be only a single Security Registrar for the Series A Bonds.

(g) The Series A Bonds shall be redeemable, at the option of the Company, at any time or from time to time, in whole or in part, at a price equal to 100% of the principal amount of the Series A Bonds to be redeemed plus accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on a Regular Record Date occurring prior to such Redemption Date to receive interest paid on the applicable Interest Payment Date that is prior to the Redemption Date) plus the applicable make-whole premium (the "Make-Whole Premium").

The amount of the Make-Whole Premium with respect to the Series A Bonds (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(i) the sum of the present values, calculated as of the Redemption Date, of:

(A) each interest payment that, but for such redemption, would have been payable on the Series A Bonds (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued and unpaid interest for the period prior to the Redemption Date); and

(B) the principal amount that, but for such redemption, would have been payable at the Stated Maturity of the Series A Bonds (or portion thereof) being redeemed,

over

(ii) the principal amount of the Series A Bonds (or portion thereof) being redeemed.

The present values of each interest and principal payment referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for such redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 30 basis points.

The Make-Whole Premium will be calculated by Credit Suisse First Boston Corporation or, if such firm is unwilling or unable to make such calculation, by an

2

independent investment banking institution of national standing appointed by the company (in any such case, an "Independent Investment Banker"). The Trustee shall have no responsibility for the calculation of the Make-Whole Premium and may conclusively presume the correctness of such calculation.

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Series A Bonds, calculated to the nearest 1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as of the third business day immediately preceding the applicable Redemption Date.

The weekly average yields of United States Treasury Notes will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield will be equal to such weekly average yield. In all other cases, the Treasury Yield will be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200 of 1% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield will be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

If less than all of the Series A Bonds are to be redeemed, the Security Registrar will select the Series A Bonds to be redeemed by such method as the Security Registrar shall deem fair and appropriate. The Trustee may select for redemption Series A Bonds and portions of Series A Bonds in amounts of $1,000 or whole multiples of $1,000, subject to clause
(i) of this Paragraph 1 (as to minimum denominations).

(h) Not applicable.

(i) The Series A Bonds are issuable only in denominations of $250,000 and integral multiples of $1000 in excess thereof.

(j) Not applicable.

(k) Not applicable.

(l) Not applicable.

(m) Not applicable.

3

(n) Not applicable.

(o) Pursuant to the terms of a registration rights agreement with one or more of the initial purchasers of the Series A Bonds (a "Registration Rights Agreement"), the Company has agreed to file an exchange offer registration statement to exchange the Series A Bonds for substantially identical Securities registered under the Securities Act of 1933, as amended (the "Securities Act") as evidence of the same underlying indebtedness. Unless otherwise specified by the Company in a supplement to this Officer's Certificate, the Securities so registered and offered and issued in exchange shall be additional Series A Bonds.The Company has also agreed to file a shelf registration statement to cover resales of the Series A Bonds, as initially issued and sold, under certain circumstances. If the Company fails to satisfy those obligations, the Company has agreed to pay liquidated damages to the holders of the Series A Bonds under certain circumstances. The terms relating to the exchange of the Series A Bonds are set forth in the Registration Rights Agreement attached hereto as Exhibit B.

(p) Not applicable.

(q) Certificates representing Series A Bonds offered and sold in reliance on Rule 144A (and only such Series A Bonds) shall be in the form of a permanent certificate in global form (a "Global Certificate") registered in the name of Cede & Co., as nominee for The Depository Trust Company (the "Depositary") to be delivered to the Depositary or its custodian, by or on behalf of the Company. The Global Certificate shall not be transferable or exchangeable, nor shall any purported transfer be registered, except as follows:

(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

(ii) the Global Certificate may be exchanged for Series A Bonds in the form of definitive certificates registered in the respective names of the beneficial owners thereof, and thereafter shall be transferable without restriction, if:

SIERRA PACIFIC POWER COMPANY, a corporation duly organized and existing under the laws of the State of Nevada (herein called the "Company," which term includes any successor corporation under the Indenture referred to below), for value received, hereby promises to pay to

****Cede & Co.****

, or registered assigns, the principal sum of THREE HUNDRED TWENTY MILLION DOLLARS on the Stated Maturity specified above, and to pay interest thereon from the Original Interest Accrual Date specified above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment Dates specified above in each year, commencing with the second Interest Payment Date next succeeding the Original Interest Accrual Date specified above, and at Maturity, at the Interest Rate per annum specified above, until the principal hereof is paid or duly provided for. The interest so payable, and paid or duly provided for, on any Interest Payment Date shall, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date specified above (whether or not a Business Day) next preceding such Interest Payment Date. Notwithstanding the foregoing, interest payable at Maturity shall be paid to the Person to whom principal shall be paid. 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.

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.

If any Interest Payment Date, any Redemption Date or the Stated Maturity shall not be a Business Day (as hereinafter defined), payment of the amounts due on this Security on such date may be made on the next succeeding Business Day; and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on such amounts for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day.

This Security is subject to redemption, at the option of the Company, at a price equal to 100% of the principal amount of this Security (or the portion hereof to be redeemed) plus accrued and unpaid interest to the Redemption Date plus the applicable make-whole premium (the "Make-Whole Premium").

The amount of the Make-Whole Premium with respect to the Securities of this series (or portion thereof) to be redeemed will be equal to the excess, if any, of:

(a) the sum of the present values, calculated as of the Redemption Date, of:

(1) each interest payment that, but for such redemption, would have been payable on such Securities (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued and unpaid interest for the period prior to the Redemption Date); and

(2) the principal amount that, but for such redemption, would have been payable at the Stated Maturity of such Securities (or portion thereof) being redeemed,

over

2

(b) the principal amount of such Securities (or portion thereof) being redeemed.

The present values of each interest and principal payment referred to in clause (a) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for such redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 30 basis points.

The Make-Whole Premium will be calculated by Credit Suisse First Boston Corporation or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Company (in any such case, an "Independent Investment Banker").

For purposes of determining the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the Securities, calculated to the nearest 1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as of the third business day immediately preceding the applicable Redemption Date.

The weekly average yields of United State Treasury Notes will be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield will be equal to such weekly average yield. In all other cases, the Treasury Yield will be calculated by interpolation, on a straight-line basis, between the weekly average yields on the United States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200 of 1% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield will be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

If less than all of the Securities are to be redeemed, the Securities Registrar will select the Securities to be redeemed by such method as the Trustee shall deem fair and appropriate. The Securities Registrar may select for redemption Securities and portions of Securities in amounts of $1,000 or whole multiples of $1,000.

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

Notice of redemption shall be given by mail to Holders of Securities, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the Trustee of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security.

3

In the event of redemption of this Security in part only, a new Security or Securities of this series, of like tenor, for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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.

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 $250,000 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

4

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 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.
