Interest on the Series H Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from Original Interest Accrual Date specified above; provided that if there is no existing Default in the payment of interest, and if this Series H Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of Series H Notes, in which case interest shall accrue from the Original Interest Accrual Date specified above; provided, further, that the first Interest Payment Date shall be October 15, 2004.

The Company shall pay interest on the Series H Notes (except Defaulted Interest) and Liquidated Damages to the Persons who are registered Holders of Series H Notes at the close of business on the April 1 and October 1 next preceding the Interest Payment Date, even if such Series H Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 3.07 of the Indenture with respect to Defaulted Interest. The Series H Notes shall be payable as to principal, premium and Liquidated Damages, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and Liquidated Damages may be made by check mailed to the Holders of Series H Notes at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, and interest, premium and Liquidated Damages on, all Global Notes and all other Series H Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 3. Paying Agent and Security Registrar. Initially, The Bank of New York, the Trustee under the Indenture, shall act as Paying Agent and Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to any Holder of Series H Notes. The Company or any of its Subsidiaries may act in any such capacity. 4. Indenture; Security. This Series H Note is one of a duly authorized issue of Securities of the Company, 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 Series H Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Series H Note is one of the series designated above. The terms of the Series H Notes include those stated in the Indenture, the Officer's Certificate dated April 16, 2004 (the "Officer's Certificate") and those made part of the Indenture by reference to the Trust Indenture Act. The Series H Notes are subject to all such terms, and Holders of Series H Notes are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Series H Note conflicts with the express provisions of the Indenture or the Officer's Certificate, the provisions of the Indenture and the Officer's Certificate shall govern and be controlling. The Series H Notes are general obligations of the Company initially limited to $100,000,000 aggregate principal amount in the case of Series H Notes issued on the Issue Date. All Outstanding Securities, including the Series H Notes, issued under the Indenture are secured by the lien of the Indenture on the properties of the Company described in the Indenture. The lien of the Indenture is junior, subject and subordinate to the prior lien of the Indenture of Mortgage dated as of December 1, 1940 between the Company and U.S. Bank National Association and Gerald R. Wheeler, as successor trustees. 5. Optional Redemption. (a) The Company may redeem the notes at any time, either in whole or in part at a redemption price equal to the greater of (1) 100% of the principal amount of the Series H Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Series H Notes being redeemed (excluding the portion of any such interest accrued to the date of redemption) discounted (for purposes of determining present value) to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points, plus, in each case, accrued interest thereon to the date of redemption. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Series H Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Series H Notes. "Comparable Treasury Price" means, with respect to any redemption date, (1) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (2) if such release (or any successor release) is not published or does not contain such prices on such third business day, the Reference Treasury Dealer Quotation for such redemption date. "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Company. "Reference Treasury Dealer" means a primary U.S. Government Securities Dealer selected by the Company. "Reference Treasury Dealer Quotation" means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at or before 5:00 p.m., New York City time, on the third business day preceding such redemption date. "Treasury Rate" means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. (b) Notwithstanding the foregoing, at any time or from time to time on or prior to April 15, 2007, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Series H Notes at a Redemption Price of 106.25% of the principal amount thereof, plus accrued and unpaid interest, if any, and Liquidated Damages thereon, if any, to the Redemption Date, with the net cash proceeds of any public or private offerings of its Equity Interests or capital contribution to the Company's equity made with net cash proceeds of an offering by Sierra Pacific Resources; provided that at least 65% of the aggregate principal amount of Series H Notes remain outstanding immediately after each occurrence of such redemption excluding Series H Notes held by the Company and its Subsidiaries; and provided, further, that each such redemption shall occur within 120 days of the date of the closing of such offering. 6. Notice of Optional Redemption. Notice of optional redemption shall be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Series H Notes are to be redeemed at its registered address. Series H Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Series H Notes held by a Holder are to be redeemed. On and after the redemption date, interest and Liquidated Damages, if any, cease to accrue on Series H Notes or portions thereof called for redemption. 7. Mandatory Redemption. (a) Other than in connection with clause (b) below or in connection with a redemption at the option of the Holders of the Series H Notes, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Series H Notes. (b) Upon the occurrence of the events described below in clauses (1) or (2) of this paragraph 7(b), the Company shall be required to redeem the Series H Notes immediately, at a Redemption Price equal to 100% of the aggregate principal amount of the Series H Notes plus accrued and unpaid interest and Liquidated Damages, if any, on the Series H Notes to the date of redemption, without further action or notice on the part of the Trustee or the Holders of the Series H Notes: the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: (I) commences a voluntary case, (II) consents to the entry of an order for relief against it in an involuntary case, (III) consents to the appointment of a custodian of it or for all or substantially all of its property, (IV) makes a general assignment for the benefit of its creditors, or (V) admits in writing of its inability to pay its debts generally as they become due; or a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (I) is for relief against the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary in an involuntary case; (II) appoints a custodian of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; or (III) orders the liquidation of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days. 8. Redemption at the Option of Holders. Upon the occurrence of any of the following Triggering Events: (a) failure for 30 days to pay when due interest on, or Liquidated Damages with respect to, the Series H Notes; (b) failure to pay when due the principal of, or premium, if any, on the Series H Notes; (c) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions described in Section 1(u)(i), 1(u)(ii) or 1(u)(vi) of the Officer's Certificate; (d) failure by the Company or any of its Restricted Subsidiaries for 30 days after notice to comply with the provisions described in Section 1(h)(iii) or (iv) of the Officer's Certificate; (e) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to comply with any of the other agreements in the Officer's Certificate or the Series H Notes; (f) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Issue Date, if that default (i) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default") or (ii) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $15.0 million or more; (g) failure by the Company or any of its Subsidiaries to pay final judgments aggregating in excess of $15.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; or (h) an event of default under the First Mortgage Indenture (other than any such matured event of default which (i) is of similar kind or character to the Triggering Event described in (c) or (e) above and (ii) has not resulted in the acceleration of the securities outstanding under the First Mortgage Indenture); provided, however, that, anything in the Officer's Certificate to the contrary notwithstanding, the waiver or cure of such event of default under the First Mortgage Indenture and the rescission and annulment of the consequences thereof under the First Mortgage Indenture shall constitute a cure of the corresponding Triggering Event and a rescission and annulment of the consequences thereof, the Holders of at least 25% in principal amount of the Series H Notes then Outstanding may deliver a notice to the Company requiring the Company to redeem the Series H Notes immediately at a Redemption Price equal to 100% of the aggregate principal amount of the Series H Notes plus accrued and unpaid interest and Liquidated Damages, if any, on the Series H Notes to the Redemption Date. The Holders of a majority in aggregate principal amount of the Series H Notes then Outstanding by notice to the Company and the Trustee may on behalf of the Holders of all of the Series H Notes waive any existing Triggering Event and its consequences except a continuing Triggering Event related to the payment of interest or Liquidated Damages on, or the principal of, the Series H Notes. In the case of any Triggering Event by reason of any willful action or inaction taken or not taken by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Series H Notes pursuant to the provisions of Section 1(g)(i) or, prior to April 15, 2007, Section 1(g)(ii) of the Officer's Certificate relating to redemption at the option of the Company, an equivalent premium equal to the premium payable under Section 1(g)(i) or, prior to April 15, 2007, Section 1(g)(ii), whichever is greater, shall also become and be immediately due and payable to the extent permitted by law upon the redemption of the Series H Notes at the option of the Holders thereof. 9.

The Security Registrar and the Trustee may require a Holder of Series H Notes, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder of Series H Notes to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Series H Note or portion of a Series H Note selected for redemption, except for the unredeemed portion of any Series H Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Series H Notes for a period of 15 days before a selection of Series H Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 10. Persons Deemed Owners. The registered Holder of a Series H Note may be treated as its owner for all purposes. 11. Amendment, Supplement and Waiver. 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 Series H Note shall be conclusive and binding upon such Holder and upon all future Holders of this Series H Note and of any Series H Note 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 Series H Note. 12. Events of Default. If an Event of Default shall occur and be continuing, the principal of this Series H Note may be declared due and payable in the manner and with the effect provided in the Indenture. 13.
