                                January 18, 2006

     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

Trustee (the "Trustee"). Section 1(u)(ix) of this Officer's Certificate sets
forth definitions of capitalized terms used herein. Terms used herein and not
otherwise defined herein shall have the meanings assigned to them in the
Indenture. Based upon the foregoing, I hereby certify on behalf of the Company

     (a) The Securities of the thirteenth series to be issued under the

     Series M, due 2016" (the "Series M Notes").

     (b) There shall be no limit upon the aggregate principal amount of the
     Series M Notes that may be authenticated and delivered under the Indenture.
     The Series M Notes shall be initially authenticated and delivered in the

     (c) Interest on the Series M Notes shall be payable to the Persons in whose

     the Company prior to the fifth day preceding the related record date (or,
     in the case of principal or premium, the fifth day preceding the date such
     principal or premium is due), the

     Company shall pay all principal, interest and premium and Liquidated
     Damages (as such term is defined herein), if any, on that Holder's Series M
     Notes in accordance with such instructions. The Corporate Trust Office of
     The Bank of New York in New York, New York shall be the place at which (i)
     the principal, interest and premium and Liquidated Damages, if any, on the

     with the first sentence of this paragraph (f)), (ii) registration of
     transfer of the Series M Notes may be effected, (iii) exchanges of the
     Series M Notes may be effected and (iv) notices and demands to or upon the

     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 or any of its Subsidiaries as

     payments of principal and interest on the Series M 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 30
     basis points, plus, in each case, accrued interest thereon to the date of
     redemption.

          customary financial practice, in pricing new issues of corporate debt
          securities of comparable maturity to the remaining term of the Series
          M Notes.

          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

          equal to the Comparable Treasury Price for such redemption date.

          (ii) Notice of Redemption. Notices of redemption shall be mailed by

               Triggering Event and a rescission and annulment of the
               consequences thereof,

     the Holders of Series M Notes of at least 25% in principal amount of the
     Series M Notes then Outstanding may deliver a notice to the Company
     requiring the Company to redeem the Series M Notes immediately at a
     Redemption Price equal to 100% of the aggregate principal amount of the
     Series M Notes plus accrued and unpaid interest and Liquidated Damages, if
     any, on the Series M Notes to the Redemption Date.

     Triggering Event related to the payment of interest or Liquidated Damages
     on, or the principal of, the Series M Notes.

          (C) 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 M
     Notes pursuant to the provisions of Section 1(g)(i), an equivalent premium
     equal to the premium payable under Section 1(g)(i) shall also become and be
     immediately due and payable to the extent permitted by law upon the
     redemption of the Series M Notes at the option of the Holders thereof.

     Liquidated Damages, if any, on the Series M Notes repurchased, to Change of
     Control Payment Date (as defined below).

          (1)  the description of the transaction or transactions that
               constitute the Change of Control, that the Change of Control

          (3)  that any Series M Note not tendered or accepted for payment shall
               continue to accrue interest and Liquidated Damages, if any;

          (4)  that, unless the Company defaults in the payment of the Change of
               Control Payment, all Series M Notes accepted for payment pursuant
               to the Change of Control Offer shall cease to accrue interest and
               Liquidated Damages, if any, after the Change of Control Payment
               Date;

          (5)  that Holders of Series M Notes electing to have any Series M
               Notes purchased pursuant to a Change of Control Offer shall be
               required to surrender the Series M Notes properly endorsed, with

               Series M Notes is withdrawing its election to have the Series M
               Notes purchased; and

          (7)  that Holders of Series M Notes whose Series M Notes are being
               purchased only in part shall be issued new Series M Notes equal

          (C) If any of the Series M Notes subject to a Change of Control Offer
     are in the form of a Global Note, then the Company shall modify such notice

     Control Payment for such Series M Notes, and the Trustee shall promptly
     authenticate and make available for delivery to each Holder of Series M
     Notes a new Series M Note equal in principal amount to any unpurchased
     portion of the Series M Notes surrendered, if any; provided that each such
     new Series M Note shall be in a principal amount of $1,000 or an integral
     multiple thereof. Any Series M Note not so accepted shall be promptly
     mailed or delivered by the Company to the Holder thereof. The Company shall
     publicly announce the results of the Change of Control Offer on or as soon
     as practicable after the Change of Control Payment Date.

          Series M Notes issued in global form shall be substantially in the

     thereby may from time to time be reduced or increased, as appropriate, to
     reflect exchanges and redemptions. Any endorsement of a Global Note to
     reflect the amount of any increase or decrease in the aggregate principal
     amount of outstanding Series M Notes represented thereby shall be made by
     the Trustee, the Depositary or the Note Custodian, at the direction of the
     Trustee, in accordance with instructions given by the Holder thereof as
     required by Section 1(q)(v) of this Officer's Certificate.

     issue on the Issue Date in the aggregate principal amount of $210,000,000
     (the "Original Notes"), (B) additional Series M Notes for original issue

     set forth in a Company Order (such additional Series M Notes, together with
     the Original Notes, the "Initial Notes") and (C) any Exchange Notes from
     time to time for issue only in exchange for a like principal amount of
     Initial Notes, in each case, upon a Company Order, which Company Order

     date of original issue thereof, (y) whether the Series M Notes are Initial
     Notes or Exchange Notes and (z) the amount of Series M Notes to be issued

          (iii) Security Registrar, Paying Agent and Depositary.

          The Company initially appoints the Trustee to act as the Security
     Registrar and Paying Agent for the Series M Notes. Upon the occurrence of
     an event set forth under Sections 1(h)(i)(B)(1) or 1(h)(i)(B)(2) herein or
     an Event of Default set forth in Sections 10.01(d) or 10.01(e) of the
     Indenture, the Trustee shall serve as Paying Agent for the Series M Notes.
     The Company shall maintain a Place of Payment for the Series M Notes within
     the City and State of New York pursuant to Section 6.02 of the Indenture.

          The Company initially appoints The Depository Trust Company ("DTC") to
     act as Depositary with respect to the Global Notes. The Trustee has been
     appointed by DTC to act as Note Custodian with respect to the Global Notes.

          (iv) Liquidated Damages, if any, to be Held in Trust.

          Payments of Liquidated Damages, if any, shall be subject to the
     provisions of Section 6.03 of the Indenture to the same extent as any
     payments of principal of or premium or interest on the Series M Notes.

          (v)  Transfer and Exchange.

          (A) Transfer and Exchange of Global Notes. A Global Note may not be
     transferred as a whole except by the Depositary to a nominee of the
     Depositary, by a nominee of the Depositary to the Depositary or to another
     nominee of the Depositary, or by the Depositary or any such nominee to a
     successor Depositary or a nominee of such successor Depositary. All Global
     Notes shall be exchanged by the Company for Definitive Notes if:

          (1)  the Company delivers to the Trustee notice from the Depositary
               that it is unwilling or unable to continue to act as Depositary
               for the Global Notes or that it is no longer a clearing agency
               registered under the Exchange Act and, in either case, a
               successor Depositary is not appointed by the Company within 90
               days after the date of such notice from the Depositary or

          (2)  the Company in its sole discretion notifies the Trustee in
               writing that it elects to cause issuance of the Series M Notes in
               certificated form; or

          (3)  there has occurred and is continuing a Default or Event of
               Default with respect to the Series M Notes.

          Upon the occurrence of either of the preceding events in (1), (2) or
          (3) above, Definitive Notes shall be issued in such names as the
          Depositary shall instruct the Trustee. Global Notes also may be
          exchanged or replaced, in whole or in part, as provided in Sections
          3.06 and 3.09 of the Indenture. Every Series M Note authenticated and
          delivered in exchange for, or in lieu of, a Global Note or any

                                       11

<PAGE>

          portion thereof, pursuant to Sections 3.06 and 3.09 of the Indenture,
          shall be authenticated and delivered in the form of, and shall be, a
          Global Note. A Global Note may not be exchanged for another Series M
          Note other than as provided in this Section 1(q)(v)(A), however,
          beneficial interests in a Global Note may be transferred and exchanged
          as provided in Section 1(q)(v)(B), (C) or (F) of this Officer's
          Certificate.

          (B) Transfer and Exchange of Beneficial Interests in the Global Notes.
     The transfer and exchange of beneficial interests in the Global Notes shall
     be effected through the Depositary, in accordance with the provisions of
     this Officer's Certificate and the Applicable Procedures. Beneficial
     interests in the Restricted Global Notes shall be subject to restrictions
     on transfer comparable to those set forth herein to the extent required by
     the Securities Act. Transfers of beneficial interests in the Global Notes
     also shall require compliance with either subparagraph (1) or (2) below, as
     applicable, as well as one or more of the other following subparagraphs as
     applicable:

               (1) Transfer of Beneficial Interests in the Same Global Note.
          Beneficial interests in any Restricted Global Note may be transferred
          to Persons who take delivery thereof in the form of a beneficial
          interest in the same Restricted Global Note in accordance with the
          transfer restrictions set forth in the Private Placement Legend;
          provided, however, that prior to the expiration of the Restricted
          Period transfers of beneficial interests in the Regulation S Global
          Note by a Distributor may not be made to a U.S. Person or for the
          account or benefit of a U.S. Person (other than an Initial Purchaser).
          Beneficial interests in any Unrestricted Global Note may be
          transferred only to Persons who take delivery thereof in the form of a
          beneficial interest in an Unrestricted Global Note. No written orders
          or instructions shall be required to be delivered to the Security
          Registrar to effect the transfers described in this Section
          1(q)(v)(B)(1).

               (2) All Other Transfers and Exchanges of Beneficial Interests in
          Global Notes. In connection with all transfers and exchanges of
          beneficial interests (other than a transfer of a beneficial interest
          in a Global Note to a Person who takes delivery thereof in the form of
          a beneficial interest in the same Global Note), the transferor of such
          beneficial interest must deliver to the Security Registrar either:

                    (a) both (i) a written order from a Participant or an
               Indirect Participant given to the Depositary in accordance with
               the Applicable Procedures directing the Depositary to credit or
               cause to be credited a beneficial interest in another Global Note
               in an amount equal to the beneficial interest to be transferred
               or exchanged and (ii) instructions given in accordance with the
               Applicable Procedures containing information regarding the
               Participant account to be credited with such increase or

                                       12

<PAGE>

                    (b) both (i) a written order from a Participant or an
               Indirect Participant given to the Depositary in accordance with
               the Applicable Procedures directing the Depositary to cause to be
               issued a Definitive Note in an amount equal to the beneficial
               interest to be transferred or exchanged and (ii) instructions
               given by the Depositary to the Security Registrar containing
               information regarding the Person in whose name such Definitive
               Note shall be registered to effect the transfer or exchange
               referred to in (i) above.

          Upon an Exchange Offer by the Company in accordance with Section
          1(q)(v)(F) of this Officer's Certificate, the requirements of this
          Section 1(q)(v)(B)(2) shall be deemed to have been satisfied upon
          receipt by the Security Registrar of the instructions contained in the
          Letter of Transmittal delivered by the Holder of such beneficial
          interests in the Restricted Global Notes. Upon notification from the
          Security Registrar that all of the requirements for transfer or
          exchange of beneficial interests in Global Notes contained in this
          Officer's Certificate, the Series M Notes and otherwise applicable
          under the Securities Act have been satisfied, the Trustee shall adjust
          the principal amount of the relevant Global Notes pursuant to Section
          1(q)(v)(H) of this Officer's Certificate.

               (3) Transfer of Beneficial Interests to Another Restricted Global
          Note. A beneficial interest in any Restricted Global Note may be
          transferred to a Person who takes delivery thereof in the form of a
          beneficial interest in another Restricted Global Note if the transfer
          complies with the requirements of clause (2) above and the Security
          Registrar receives the following:

                    (a) if the transferee shall take delivery in the form of a
               beneficial interest in the Rule 144A Global Note, then the
               transferor must deliver a certificate in the form of Exhibit B
               hereto, including the certifications in Item (1) thereof; or

                    (b) if the transferee shall take delivery in the form of a
               beneficial interest in the Regulation S Global Note, then the
               transferor must deliver a certificate in the form of Exhibit B
               hereto, including the certifications in Item (2) thereof.

               (4) Transfer and Exchange of Beneficial Interests in a Restricted
          Global Note for Beneficial Interests in the Unrestricted Global Note.
          A beneficial interest in any Restricted Global Note may be exchanged
          by any holder thereof for a beneficial interest in an Unrestricted
          Global Note or transferred to a Person who takes delivery thereof in
          the form of a beneficial interest in an Unrestricted Global Note if
          the exchange or transfer complies with the requirements of clause (2)
          above and:

                    (a) such exchange or transfer is effected pursuant to an
               Exchange Offer in accordance with the Registration Rights
               Agreement and the

                                       13

<PAGE>

               holder of the beneficial interest to be transferred, in the case
               of an exchange, or the transferee, in the case of a transfer, is
               not (i) a broker-dealer, (ii) a Person participating in the
               distribution of the Exchange Notes or (iii) a Person who is an
               affiliate (as defined in Rule 144) of the Company;

                    (b) any such transfer is effected pursuant to a Shelf
               Registration Statement in accordance with the Registration Rights
               Agreement;

                    (c) any such transfer is effected by a Broker-Dealer
               pursuant to an Exchange Offer Registration Statement in
               accordance with the Registration Rights Agreement; or

                    (d) the Security Registrar receives the following:

               (i) if the holder of such beneficial interest in a Restricted
     Global Note proposes to exchange such beneficial interest for a beneficial
     interest in an Unrestricted Global Note, a certificate from such holder in
     the form of Exhibit C hereto, including the certifications in Item (1)(a)
     thereof; or

               (ii) if the holder of such beneficial interest in a Restricted
     Global Note proposes to transfer such beneficial interest to a Person who
     shall take delivery thereof in the form of a beneficial interest in an
     Unrestricted Global Note, a certificate from such holder in the form of
     Exhibit B hereto, including the certifications in Item (4) thereof;

     and, in each such case set forth in this subparagraph (d), an Opinion of
     Counsel in form reasonably acceptable to the Company to the effect that
     such exchange or transfer is in compliance with the Securities Act and that
     the restrictions on transfer contained herein and in the Private Placement
     Legend are not required in order to maintain compliance with the Securities
     Act.

          If any such transfer is effected pursuant to subparagraph (b) or (d)
     above at a time when an Unrestricted Global Note has not yet been issued,
     the Company shall issue and, upon receipt of an authentication order in
     accordance with Section 1(q)(ii) of this Officer's Certificate, the Trustee
     shall authenticate one or more Unrestricted Global Notes in an aggregate
     principal amount equal to the principal amount of beneficial interests
     transferred pursuant to subparagraph (b) or (d) above.

          Beneficial interests in an Unrestricted Global Note cannot be
     exchanged for, or transferred to Persons who take delivery thereof in the
     form of, a beneficial interest in a Restricted Global Note.

          (C)  Transfer or Exchange of Beneficial Interests for Definitive
               Notes.

               (1) Beneficial Interests in Restricted Global Notes to Restricted

               interest for a Restricted Definitive Note, a certificate from
               such holder in the form of Exhibit C hereto, including the
               certifications in Item (2)(a) thereof;

               certifications in Item (2) thereof;

               pursuant to an exemption from the registration requirements of
               the Securities Act in accordance with Rule 144 under the
               Securities Act, a certificate to the effect set forth in Exhibit
               B hereto, including the certifications in Item (3)(a) thereof;

                    (e) if such beneficial interest is being transferred to an
               Institutional Accredited Investor or in reliance on any other
               exemption from the registration requirements of the Securities
               Act, in either case other than those listed in subparagraphs (b)
               through (d) above, then the transferor must deliver a certificate
               in the form of Exhibit B hereto, including the certifications,
               certificates and any Opinion of Counsel required by Item (3)

     the Trustee, upon notice of receipt of such documentation by the Security
     Registrar, shall cause the aggregate principal amount of the applicable
     Global Note to be reduced accordingly pursuant to Section 1(q)(v)(H) of

<PAGE>

     shall execute and the Trustee shall authenticate and make available for
     delivery to the Person designated in the instructions a Definitive Note in
     the appropriate principal amount. Any Definitive Note issued in exchange
     for a beneficial interest in a Restricted Global Note pursuant to this
     Section 1(q)(v)(C) shall be registered in such name or names and in such
     authorized denomination or denominations as the holder of such beneficial
     interest shall instruct the Security Registrar through instructions from
     the Depositary and the Participant or Indirect Participant. The Trustee
     shall make available for delivery such Definitive Notes to the Persons in

     issued in exchange for a beneficial interest in a Restricted Global Note
     pursuant to this Section 1(q)(v)(C)(1) shall bear the Private Placement
     Legend and shall be subject to all restrictions on transfer contained

     transfer is pursuant to an exemption from the registration requirements of
     the Securities Act other than Rule 903 or Rule 904.

               (2) Beneficial Interests in Restricted Global Notes to

          hereof, a holder of a beneficial interest in a Restricted Global Note
          may exchange such beneficial interest for an Unrestricted Definitive
          Note or may transfer such beneficial interest to a Person who takes
          delivery thereof in the form of an Unrestricted Definitive Note only

          interest for a Definitive Note or to transfer such beneficial interest
          to a Person who takes delivery thereof in the form of a Definitive
          Note, then, upon notice by the Security Registrar of satisfaction of
          the conditions set forth in Section 1(q)(v)(B)(2) of this Officer's
          Certificate, the Trustee shall cause the aggregate principal amount of

          1(q)(v)(C)(3) shall be registered in such name or names and in such
          authorized denomination or denominations as the holder of such
          beneficial interest shall instruct the Security Registrar through
          instructions from the Depositary and the Participant or Indirect
          Participant. The Trustee shall make available for delivery such

          interest pursuant to this Section 1(q)(v)(C)(3) shall not bear the
          Private Placement Legend. A beneficial interest in an Unrestricted
          Global Note cannot be exchanged for a Definitive Note bearing the
          Private Placement Legend or transferred to a Person who takes delivery
          thereof in the form of a Definitive Note bearing the Private Placement
          Legend.

               (2) Global Note Legend. Each Global Note shall bear a legend in
          substantially the following form:

     "THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE OFFICER'S
     CERTIFICATE UNDER THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN
     CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT
     TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE
     TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO

     (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE
     PRIOR WRITTEN CONSENT OF THE COMPANY OR ANY SUCCESSOR THERETO."

          Additionally, for so long as DTC is the Depositary with respect to any
     Global Note, each such Global Note shall also bear a legend in
     substantially the following form:

          (H) Cancellation and/or Adjustment of Global Notes. At such time as
     all beneficial interests in a particular Global Note have been exchanged
     for Definitive Notes or a particular Global Note has been redeemed,
     repurchased or canceled in whole and not in part, each such Global Note
     shall be returned to or retained and canceled by the Trustee in accordance
     with Section 3.09 of the Indenture. At any time prior to such cancellation,
     if any beneficial interest in a Global Note is exchanged for or transferred
     to a Person who shall take delivery thereof in the form of a beneficial
     interest in another Global Note or for Definitive Notes, the principal
     amount of Series M Notes represented by such Global Note shall be reduced
     accordingly and an endorsement shall be made on such Global Note, by the
     Trustee, the Note Custodian or the Depositary at the direction of the
     Trustee, to reflect such reduction; and if the beneficial interest is being
     exchanged for or transferred to a Person who shall take delivery thereof in
     the form of a beneficial interest in another Global Note, such other Global
     Note shall be increased accordingly

                                       24

     and an endorsement shall be made on such Global Note, by the Trustee, the
     Note Custodian or by the Depositary at the direction of the Trustee, to
     reflect such increase.

          (I)  General Provisions Relating to Transfers and Exchanges.

          (1) To permit registrations of transfers and exchanges, subject to
     Section 1(q)(v) of this Officer's Certificate, the Company shall execute
     and, upon the Company's order, the Trustee or an Authenticating Agent shall
     authenticate Global Notes and Definitive Notes at the Security Registrar's

     to be submitted to the Security Registrar pursuant to this Section 1(q)(v)
     to effect a transfer or exchange may be submitted by facsimile.

          (3) The Trustee and the Security Registrar shall have no obligation or
     duty to monitor, determine or inquire as to whether any Person is or is not
     a Person described in clauses (i), (ii) and (iii) of each of Sections
     1(q)(v)(B)(4)(a), 1(q)(v)(C)(2)(a), 1(q)(v)(D)(2)(a), 1(q)(v)(E)(2)(a) and
     1(q)(v)(F) of this Officer's Certificate or under applicable law (other
     than the Trust Indenture Act) with respect to any transfer of any interest
     in any Series M Note (including any transfers between or among Participants
     or beneficial owners of interests in any Global Note) other than to require
     delivery of such certificates and other documentation or evidence as are
     expressly required by, and to do so if and when expressly required by the
     terms of, this Indenture, and to examine the same to determine substantial
     compliance as to form with the express requirements hereof.

          (vi) Outstanding Series M Notes.

          Notwithstanding the definition of "Outstanding" in Section 1.01 of the
     Indenture, Series M Notes that the Company, a Subsidiary of the Company or
     an Affiliate of the Company offers to purchase or acquires pursuant to an
     offer, exchange offer, tender offer or otherwise shall not be deemed to be
     owned by the Company, such Subsidiary or such Affiliate until legal title
     to such Series M Notes passes to the Company, such Subsidiary or such
     Affiliate, as the case may be.

     (r) Not applicable.

     (s) The Series M Notes have not been registered under the Securities Act
     and may not be offered, sold or otherwise transferred in the absence of
     such registration or an applicable exemption therefrom. No service charge
     shall be made for the registration of transfer or exchange of the Series M
     Notes; provided, however, 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 (other than any such transfer
     taxes or similar governmental charge payable upon exchange or transfer
     pursuant to Sections 1.06(f), 3.04, 5.06 or 14.06 of the Indenture and
     Section 1(h)(iii) of this Officer's Certificate not involving any

     dispose of all or substantially all of the properties or assets of the
     Company and its Restricted Subsidiaries taken as a whole, in one or more
     related transactions, to another Person; unless:

          (1)  either: (a) the Company is the surviving corporation; or (b) the
               Person formed by or surviving any such consolidation or merger

               corporation organized or existing under the laws of the United
               States, any state of the United States or the District of

          (2)  (a) the Person formed by or surviving any such consolidation or
               merger (if other than the Company) or the Person to which such

               Agreement pursuant to agreements reasonably satisfactory to the
               Trustee; and (b) such Person executes and delivers to the Trustee
               a supplemental indenture that contains a grant, conveyance,
               transfer and mortgage by such Person confirming the lien of the
               Indenture on the property subject to such lien and subjecting to
               such lien all property thereafter acquired by such Person that
               shall constitute an improvement, extension or addition to the
               property subject to the lien of the Indenture or renewal,
               replacement or substitution of or for any part thereof and, at

          (3)  immediately after such transaction no Default or Event of Default
               exists; and

          (4)  the Company, or the Person formed by or surviving any such

               such sale, assignment, transfer, conveyance or other disposition
               has been made, shall have delivered to the Trustee an Officer's
               Certificate and an Opinion of Counsel, each stating that such
               transaction and any supplemental indenture entered into in
               connection therewith complies with all of the terms of this
               Section 1(u)(ii) and that all conditions precedent provided for
               in this Section 1(u)(ii) relating to such transaction or series
               of transactions have been complied with.

          (B) In addition, the Company may not, directly or indirectly, lease
     all or substantially all of its properties or assets, in one or more

     surviving any such consolidation or merger (if other than the Company) or
     to which such sale, assignment, transfer, conveyance or other disposition
     has been made, shall be deemed a Successor Corporation under the Indenture.

          (iii) Future Subsidiary Guarantees.

          (A) The Company shall not permit any Restricted Subsidiary to
     guarantee the payment of any Indebtedness of the Company unless:

          (1)  such Restricted Subsidiary simultaneously executes and delivers
               to the Trustee a Subsidiary Guarantee of such Restricted
               Subsidiary except that with respect to a Guarantee of
               Indebtedness of the Company if such Indebtedness is by its
               express terms subordinated in right of payment to the Series M
               Notes, any such Guarantee of such Restricted Subsidiary with
               respect to such Indebtedness shall be subordinated in right of
               payment to such Restricted Subsidiary's Subsidiary Guarantee with
               respect to the Series M Notes substantially to the same extent as
               such Indebtedness is subordinated to the Series M Notes;

          (2)  such Restricted Subsidiary waives and shall not in any manner
               whatsoever claim or take the benefit or advantage of, any rights
               or reimbursement, indemnity or subrogation or any other rights
               against the Company or any other Restricted Subsidiary as a
               result of any payment by such Restricted Subsidiary under its
               Subsidiary Guarantee of the Series M Notes; and

                                       27

<PAGE>

          (3)  such Restricted Subsidiary shall deliver to the Trustee an
               Opinion of Counsel to the effect that (a) such Subsidiary
               Guarantee has been duly executed and authorized and (b) such
               Subsidiary Guarantee constitutes a valid, binding and enforceable
               obligation of such Restricted Subsidiary, except insofar as
               enforcement thereof may be limited by bankruptcy, insolvency or
               similar laws (including, without limitation, all laws relating to
               fraudulent transfers) and except insofar as enforcement thereof
               is subject to general principles of equity; provided that this
               Section 1(u)(iii)(A) shall not be applicable to any Guarantee of
               any Restricted Subsidiary that (x) existed at the time such
               Person became a Restricted Subsidiary of the Company and (y) was
               not incurred in connection with, or in contemplation of, such
               Person becoming a Restricted Subsidiary of the Company.

          (B) Notwithstanding the foregoing and the other provisions of this
     Officer's Certificate, in the event a Subsidiary Guarantor is sold or
     disposed of (whether by merger, consolidation, the sale of its Capital
     Stock or the sale of all or substantially all of its assets (other than by
     lease) and whether or not the Subsidiary Guarantor is the surviving
     corporation in such transaction) to a Person which is not the Company or a
     Restricted Subsidiary of the Company (other than a Receivables Entity),
     such Subsidiary Guarantor shall be released from its obligations under its
     Subsidiary Guarantee if:

          (1)  the sale or other disposition is in compliance with the
               applicable provisions of this Officer's Certificate; and

          (2)  the Subsidiary Guarantor is also released or discharged from its
               obligations under the Guarantee which resulted in the creation of
               such Subsidiary Guarantee, except by or as a result of payment
               under such Guarantee.

          (iv) Sale and Leaseback Transactions.

          (A) The Company shall not, and shall not permit any of its Restricted
     Subsidiaries to, enter into any sale and leaseback transaction; provided
     that the Company or any Restricted Subsidiary may enter into a sale and
     leaseback transaction if the gross cash proceeds of that sale and leaseback
     transaction are at least equal to the fair market value, as determined in
     good faith by the Board of Directors and set forth in an Officer's
     Certificate delivered to the Trustee, of the property that is the subject
     of that sale and leaseback transaction.

          (v)  Payments for Consent.

          The Company shall not, and shall not permit any of its Subsidiaries
     to, directly or indirectly, pay or cause to be paid any consideration to or
     for the benefit of any Holder of Series M Notes for or as an inducement to
     any consent, waiver or amendment of any of the terms or provisions of this
     Officer's Certificate or the Series M Notes unless such

                                       28

<PAGE>

     consideration is offered to be paid and is paid to all Holders of the
     Series M Notes that consent, waive or agree to amend in the time frame set
     forth in the solicitation documents relating to such consent, waiver or
     agreement.

          (vi) Covenant Defeasance.

          (A) Option to Effect Covenant Defeasance. The Company may, at the
     option of the Board of Directors evidenced by a resolution set forth in an
     Officers' Certificate, at any time, elect to have Section 1(u)(vi)(B)
     hereof be applied to all outstanding Series M Notes upon compliance with
     the conditions set forth below in Section 1(u)(vi)(C) hereof.

          (B) Exercise of Covenant Defeasance. Upon the Company's exercise under
     Section 1(u)(vi)(A) hereof of the option applicable to this Section
     1(u)(vi)(B), the Company shall, subject to the satisfaction of the
     conditions set forth in Section 1(u)(vi)(C) hereof, be released from each
     of its obligations under the covenants contained in Section 1(h)(iii),
     Section 1(u)(i), Section 1(u)(iii), Section 1(u)(iv), Section 1(u)(v)
     hereof (under the headings: "Mandatory Redemption/Redemption at Option of
     Holders/Offers to Purchase--Offer to Purchase Upon Change of Control,"
     "Certain Covenants and Definitions--Liens," "Certain Covenants and
     Definitions--Future Subsidiary Guarantees," "Certain Covenants and
     Definitions--Sale and Leaseback Transactions," and "Certain Covenants and
     Definitions--Payment for Consents") hereof with respect to the Outstanding
     Series M Notes on and after the date the conditions set forth in Section
     1(u)(vi)(C) hereof are satisfied (hereinafter, "Covenant Defeasance"), and
     the Series M Notes shall thereafter be deemed not Outstanding for the
     purposes of any direction, waiver, consent or declaration or act of Holders
     of Securities, including but not limited to, Holders of Series M Notes (and
     the consequences of any thereof) in connection with such covenants, but
     will continue to be deemed Outstanding for all other purposes hereunder.
     For this purpose, Covenant Defeasance means that, with respect to the
     Outstanding Series M Notes, the Company may omit to comply with and will
     have no liability in respect of any term, condition or limitation set forth
     in any such covenant, whether directly or indirectly, by reason of any
     reference elsewhere herein to any such covenant or by reason of any
     reference in any such covenant to any other provision herein or in any
     other document and such omission to comply will not constitute a Triggering
     Event under Section 1(h)(ii) hereof or a Default or an Event of Default
     under Section 10.01 of the Indenture, but, except as specified above, the
     remainder of the Indenture, this Officer's Certificate and such Series M
     Notes will be unaffected thereby. In addition, upon the Company's exercise
     under Section 1(u)(vi)(A) hereof of the option applicable to Section
     1(u)(vi)(B) hereof, subject to the satisfaction of the conditions set forth
     in Section 1(u)(vi)(C) hereof, Sections 1(h)(ii)(A)(3) through
     1(h)(ii)(A)(7) hereof will not constitute Triggering Events.

          (C) Conditions to Covenant Defeasance. In order to exercise Covenant
     Defeasance under this Section 1(u)(vi):

                                       29

                    to the Indenture) in an amount which will be sufficient, or

               (b)  Eligible Obligations which do not contain provisions

                    interest on which when due, without any regard to
                    reinvestment thereof, will provide monies which, together
                    with the money, if any, deposited with or held by the

                    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

               Covenant Defeasance had not occurred;

          (3)  no Triggering Event shall have occurred and be continuing on the
               date of such deposit (other than a Triggering Event arising from
               the breach of a covenant under this Officer's Certificate
               resulting from the borrowing of funds to be applied to such
               deposit);

          (4)  such Covenant Defeasance will not result in a breach or violation
               of, or constitute a default under any material agreement or

               stating that the deposit was not made by the Company with the
               intent of preferring the Holders of Series M Notes over the other
               creditors of the Company with the intent of defeating, hindering,
               delaying or defrauding creditors of the Company or others; and

demand at the same rate to the extent lawful. Interest shall be computed on the
basis of a 360-day year of twelve 30-day months.

     2. Method of Payment. The Company shall pay interest on the Series M Notes
(except Defaulted Interest) and Liquidated Damages to the Persons who are
registered Holders of Series M Notes at the close of business on the March 1 and
September 1 next preceding the Interest Payment Date, even if such Series M
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 M 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 M 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 M 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 M Notes. The Company or any of its Subsidiaries
may act in any such capacity.

     4. Indenture; Security. This Series M 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 M 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 M Note is one of the series designated above. The
terms of the Series M Notes include those stated in the Indenture, the Officer's
Certificate dated January 18, 2006 (the "Officer's Certificate") and those made
part of

                                       A-2

<PAGE>

the Indenture by reference to the Trust Indenture Act. The Series M Notes are
subject to all such terms, and Holders of Series M Notes are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Series M 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 M Notes are
general obligations of the Company initially limited to $210,000,000 aggregate
principal amount in the case of Series M Notes issued on the Issue Date.

     All Outstanding Securities, including the Series M 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
October 1, 1953 between the Company and Deutsche Bank Trust Company Americas, as
trustee.

     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 M Notes being redeemed and (2) the sum of the present
values of the remaining scheduled payments of principal and interest on the
Series M 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 30 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 M 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 M 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.

                                       A-3

<PAGE>

          "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.

     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 M Notes are to be redeemed at its registered address.
Series M 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 M Notes held by a
Holder are to be redeemed. Notices of redemption may not be conditional. On and
after the redemption date, interest and Liquidated Damages, if any, cease to
accrue on Series M 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 M Notes in Section
8 below, the Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Series M 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 M Notes immediately, at a Redemption Price equal to 100% of the aggregate
principal amount of the Series M Notes plus accrued and unpaid interest and
Liquidated Damages, if any, on the Series M Notes to the date of redemption,
without further action or notice on the part of the Trustee or the Holders of
the Series M Notes:

          (1)  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

                    or

               (V)  admits in writing of its inability to pay its debts
                    generally as they become due; or

          (2)  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

                    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 M Notes; (b) failure to
pay when due the principal of, or premium, if any, on the Series M Notes; (c)
failure by the Company or any of its Restricted Subsidiaries to comply with the
provisions described in Section 1(u)(ii) 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) 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 M 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 original issue
date of the Series M Notes, 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

                                       A-5

<PAGE>

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 M Notes then Outstanding may deliver a notice to the Company requiring
the Company to redeem the Series M Notes immediately at a Redemption Price equal
to 100% of the aggregate principal amount of the Series M Notes plus accrued and
unpaid interest and Liquidated Damages, if any, on the Series M Notes to the
Redemption Date. The Holders of a majority in aggregate principal amount of the
Series M Notes then Outstanding by notice to the Company and the Trustee may on
behalf of the Holders of all of the Series M 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 M
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 M Notes pursuant to the provisions
of Section 1(g)(i) 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) shall also become and be immediately due and payable to the
extent permitted by law upon the redemption of the Series M Notes at the option
of the Holders thereof.

     9. Denominations, Transfer, Exchange. The Series M Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Series M Notes may be registered and Series M Notes may
be exchanged as provided in the Indenture and the Officer's Certificate. The
Security Registrar and the Trustee may require a Holder of Series M Notes, among
other things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder of Series M 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 M Note or portion of a Series M Note
selected for redemption, except for the unredeemed portion of any Series M Note
being redeemed in part. Also, the Company need not exchange or register the
transfer of any Series M Notes for a period of 15 days before a selection of
Series M 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 M Note may be
treated as its owner for all purposes.

                                       A-6

<PAGE>

     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 M
Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Series M Note and of any Series M 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 M
Note.

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

     13. No Recourse Against Others. 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.

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

                                       A-7

thereupon one or more new Series M Notes of this series of authorized
denominations and of like tenor and aggregate principal amount, will be issued
to the designated transferee or transferees.

          (b) 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.

          (c) Prior to due presentment of this Series M Note 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 Series M Note is registered as the
absolute owner hereof for all purposes, whether or not this Series M Note be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     17. Definition of "Business Day" and Other Terms. As used herein, "Business

Agreement dated as of November 16, 2004 between Nevada Power Company and the
parties named on the signature pages thereof (the "Registration Rights
Agreement").

     20. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Series M Notes and the Trustee may use CUSIP
numbers in notices of redemption

                                       A-8

<PAGE>

as a convenience to Holders of Series M Notes. No representation is made as to
the accuracy of such numbers either as printed on the Series M Notes or as

<PAGE>

     3(a)(5)(A) of the Securities Act that is acquiring Notes as fiduciary for
     the account of one or more institutions for which we exercise sole

     accounts for which we are acting as fiduciary shall remain at all times
     within our control;

6.   we have received a copy of the Offering Memorandum relating to the offering
     of the Notes and acknowledge that we have had access to such financial and
     other information, and have been afforded the opportunity to ask such
     questions of representatives of the Company and receive answers thereto, as
     we deem necessary in connection with our decision to purchase the Notes;
     and

7.   (vii)(a) we are not an employee benefit plan or other arrangement that is

          We understand that the Notes were offered in a transaction not
involving any public offering in the United States within the meaning of the
Securities Act and that the Notes have not been registered under the Securities
Act or any state securities laws, and they were offered for resale in
transactions not requiring registration under the Securities Act. We agree on

Notes will agree, to offer, sell or otherwise transfer such notes prior to (x)

institutional buyer to whom notice is given that the transfer is being made

or the property of such investor account or accounts be at all times within its
or their control and in compliance with any applicable state securities laws.
Subject to the procedures set forth under Section 1(q)(v) of the Officer's
Certificate, prior to any proposed transfer of the Notes (otherwise than

<PAGE>

Accrual Date specified above; provided that if there is no existing Default in
the payment of interest, and if this Series M 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 M Notes, in which

interest in any proceeding under the Bankruptcy Law) on overdue principal and
premium, if any, from time to time on demand at the rate borne on the Series M

under the Bankruptcy Law) on overdue installments of interest and Liquidated
Damages, if any, (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest shall be computed

     2. Method of Payment. The Company shall pay interest on the Series M Notes
(except Defaulted Interest) and Liquidated Damages to the Persons who are

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 M 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

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 M Notes. The Company or any of its Subsidiaries
may act in any such capacity.

     4. Indenture; Security. This Series M 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

<PAGE>

of this Series M 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 M Note is one of the series designated above. The terms of the Series M
Notes include those stated in the Indenture, the Officer's Certificate dated
January 18, 2006 (the "Officer's Certificate") and those made part of the
Indenture by reference to the Trust Indenture Act. The Series M Notes are
subject to all such terms, and Holders of Series M Notes are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Series M 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 M Notes are
general obligations of the Company initially limited to $210,000,000 aggregate
principal amount in the case of Series M Notes issued on the Issue Date.

     All Outstanding Securities, including the Series M 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
October 1, 1953 between the Company and Deutsche Bank Trust Company Americas, as
trustee.

     5. Optional Redemption. The Company may redeem the Series M 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 M Notes being redeemed and (2)
the sum of the present values of the remaining scheduled payments of principal
and interest on the Series M 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 30 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 M 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 M 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.

<PAGE>

          "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.

     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 M Notes are to be redeemed at its registered address.
Series M 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 M Notes held by a
Holder are to be redeemed. Notices of redemption may not be conditional. On and
after the redemption date, interest and Liquidated Damages, if any, cease to
accrue on Series M Notes or portions thereof called for redemption.

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

<PAGE>

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 M Notes then
Outstanding may deliver a notice to the Company requiring the Company to redeem
the Series M Notes immediately at a Redemption Price equal to 100% of the
aggregate principal amount of the Series M Notes plus accrued and unpaid
interest and Liquidated Damages, if any, on the Series M Notes to the Redemption
Date. The Holders of a majority in aggregate principal amount of the Series M
Notes then Outstanding by notice to the Company and the Trustee may on behalf of
the Holders of all of the Series M 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 M 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 M Notes pursuant to the provisions of
Section 1(g)(i) 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) shall also become and be immediately due and payable to the
extent permitted by law upon the redemption of the Series M Notes at the option
of the Holders thereof.

     9. Denominations, Transfer, Exchange. The Series M Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Series M Notes may be registered and Series M Notes may
be exchanged as provided in the Indenture and the Officer's Certificate. The
Security Registrar and the Trustee may require a Holder of Series M Notes, among
other things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder of Series M 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 M Note or portion of a Series M Note
selected for redemption, except for the unredeemed portion of any Series M Note
being redeemed in part. Also, the Company need not exchange or register the
transfer of any Series M Notes for a period of 15 days before a selection of
Series M 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 M 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,

<PAGE>

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 M Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Series M Note and
of any Series M 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 M Note.

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

     13. No Recourse Against Others. 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.

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

     15. Transfer and Exchange.

          (a) As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Series M Note is registrable in the
Security Register, upon surrender of this Series M Note for registration of
transfer at the Corporate Trust Office of The Bank of New

<PAGE>

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 Series M Notes of this series of
authorized denominations and of like tenor and aggregate principal amount, will
be issued to the designated transferee or transferees.

          (b) 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.

          (c) Prior to due presentment of this Series M Note 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 Series M Note is registered as the
absolute owner hereof for all purposes, whether or not this Series M Note be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary.

     16. Governing Law. The Series M Notes shall be governed by and construed in
accordance with the laws of the State of New York.

     17. Definition of "Business Day" and Other Terms. As used herein, "Business
Day" shall mean any day, other than Saturday or Sunday, on which commercial
banks are open for business, including dealings in deposits in U.S. dollars, in
New York. All other terms used in this Series M Note which are defined in the
Indenture or the Officer's Certificate shall have the meanings assigned to them
in the Indenture or the Officer's Certificate, as applicable, unless otherwise
indicated.

     18. Abbreviations. Customary abbreviations may be used in the name of a
Holder of Series M Notes or an assignee, such as: TEN COM (= tenants in common),
TEN ENT (= tenants by the entireties), JT TEN joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

     19. Additional Rights of Holders of Restricted Global Notes and Restricted
Definitive Notes. In addition to the rights provided to Holders of Series M
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of January 18, 2006 between Nevada Power Company and the
parties named on the signature pages thereof (the "Registration Rights
Agreement").

     20. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Series M Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders of Series M Notes.
No representation is made as to the accuracy of such numbers either as printed
on the Series M Notes or as contained in any notice of redemption and reliance
may be placed only on the other identification numbers placed thereon.
