Dear Sirs:

    Sierra Pacific Power Company, a Nevada corporation (the "Company"), 
proposes to issue and sell from time to time its Collateralized Medium-Term 
Notes, Series D, due from nine months to 40 years from the date of issue, in 
an initial aggregate principal amount of $35,000,000 (the "Notes") and agrees 
with each of you (individually, an "Agent" and collectively, the "Agents") as 
set forth in this Agreement.

    The Notes are to be issued from time to time pursuant to an indenture, 
dated as of June 1, 1992 (as heretofore supplemented and as supplemented by 
the Fourth Supplemental Indenture dated as of February 1, 1997 relating to 
the Notes (the "Fourth Supplemental Indenture") and as it may be further 
supplemented or amended from time to time (the "Indenture"), between the 
Company and Bankers Trust Company, as trustee (the "Trustee").  The Notes 
will be secured by one or more first mortgage bonds (the "Mortgage Bonds") to 
be issued and delivered by the Company to the Trustee.  The Mortgage Bonds 
will be issued pursuant to an Indenture of Mortgage, dated as of December 1, 
1940, from the Company's predecessor to The New England Trust Company (State 
Street Bank & Trust Company, as successor trustee) and Leo W. Huegle (Gerald 
R. Wheeler, as successor trustee), as amended and supplemented and as it will 
be further supplemented by a Thirty-fifth Supplemental Indenture dated as of 
February 1, 1997 (said Indenture of Mortgage, as so amended and supplemented 
and to be supplemented, and said supplemental indenture, being hereinafter 
referred to as the "Mortgage Indenture" and the "Thirty-fifth Supplemental 
Indenture", respectively).

<PAGE>

    The Notes shall have the maturity ranges, applicable interest rates or 
interest rate formulas, issue prices, redemption and repayment provisions and 
other terms set forth in the Prospectus referred to in Section l(c) hereof as 
it may be amended or supplemented from time to time, including any Pricing 
Supplement (as such term is defined in Section 3(a) hereof).  The Notes will 
be issued, and the terms thereof established, from time to time, by the 
Company in accordance with the Indenture and the Procedures referred to in 
Section 2(f) hereof.  This Agreement shall only apply to sales of the Notes 
and not to sales of any other securities or evidences of indebtedness of the 
Company and only on the specific terms set forth herein.

    Subject to the terms and conditions stated herein and subject to the 
reservation by the Company of the right to sell its Notes directly on its own 
behalf or to designate or select additional agents as set forth in Section 11 
hereof, the Company hereby (i) appoints each of the Agents as the 
co-exclusive agents of the Company for the purpose of soliciting or receiving 
offers to purchase Notes from the Company and (ii) agrees that whenever the 
Company determines to sell Notes directly to an Agent as principal it will 
enter into a separate agreement (each a "Purchase Agreement").  Each such 
Purchase Agreement, whether oral (and confirmed in writing, which may be by 
facsimile transmission) or in writing, shall contain such information (as 
applicable) set forth in the form of Purchase Agreement attached as Exhibit A 
to this Agreement, relating to such sale in accordance with Section 2(e) 
hereof.

    SECTION l.  Representations and Warranties.  The Company represents and 
warrants to each Agent as of the date hereof, as of the Commencement Date 
referred to in Section 2(g) hereof, and as of the times referred to in 
Sections 6(a) and 6(b) hereof (the Commencement Date and each such time being 
hereinafter sometimes referred to as a "Representation Date"), as follows:

         (a)  The Company is a corporation duly organized, validly existing 
    and in good standing under the laws of the State of Nevada, has the

    business as now conducted and has the corporate power and authority to 
    carry on its business as presently proposed to be conducted, all as 
    described in the Prospectus hereinafter referred to; and the Company is 
    duly qualified and is authorized to do business and is in good standing 
    as a foreign corporation in each jurisdiction where the ownership or 
    character of its properties or the nature of its business or activities 
    makes such qualification necessary and where the failure so to qualify or 
    be in good standing would have a material adverse effect on the condition 
    (financial or other), net worth or results of operations of the Company 
    and its subsidiaries considered as one enterprise.  All of the 
    outstanding shares of Common Stock of the Company are validly issued and 
    are held of record by Sierra Pacific Resources, a Nevada corporation.

         (b)  Each of the subsidiaries of the Company is a corporation duly 
    organized, validly existing and in good standing under the laws of its 
    jurisdiction of incorporation, has the corporate power and authority to 
    own or lease and operate its properties, has the corporate power, 
    authority and franchises to carry on its business as now conducted and 
    has the corporate power and authority to carry on its business as 
    presently proposed to be conducted; each of the subsidiaries of the 
    Company is duly qualified and is authorized to do business and is in good 
    standing as a foreign corporation in each jurisdiction where the failure 
    so to qualify or be in good standing would have a material adverse effect 
    on the condition (financial or other), net worth or results of operations 
    of the Company and its subsidiaries considered as one enterprise; all of 
    the outstanding shares of capital stock of each subsidiary of the Company 
    have been duly authorized and validly issued and are fully paid and 
    nonassessable; and all of the capital stock of each such subsidiary owned 
    by the Company, directly or through subsidiaries, is owned free and clear 
    of any security interest, mortgage, pledge, lien, encumbrance, claim or 
    equity.

         (c)  A registration statement on Form S-3, including a prospectus, 
    relating to the Notes has been filed with the Securities and Exchange 
    Commission (the "Commission") and has become effective.  No order 
    preventing or suspending the use or effectiveness of the Prospectus (as 
    defined below) has been issued by the Commission or is in effect, and no 
    proceedings for such purpose are pending before or threatened by the 
    Commission.  Such registration statement in the form in which it became 
    effective, and as from time to time supplemented, and including all 
    exhibits thereto is referred to as the "Registration Statement"; the 
    prospectus relating to the Notes in the form in which it has most 
    recently been filed, or transmitted for filing, with the Commission 
    pursuant to Rule 424 under the Securities Act of 1933, as amended (the 
    "Act"), together with all amendments or supplements thereto, is 
    hereinafter referred to as the "Prospectus."  Any reference to the Act 
    shall include the rules and regulations of the Commission promulgated 
    thereunder.  Any reference to the Registration Statement or Prospectus or 
    any amendment or supplement thereto shall include all documents 
    incorporated by reference therein (the "Incorporated Documents") pursuant 
    to the applicable form under the Act. The Registration Statement and the 
    Prospectus comply, and will, as amended or supplemented, if applicable, 
    comply at all times during any Marketing Period (as defined below), in 
    all material respects with the requirements of the Act and do not and 
    will not contain any untrue statement of a material fact or omit to state 
    a material fact required to be stated therein or necessary to make the 
    statements therein, in light of the circumstances under which they were 
    or are made, not misleading, except that the foregoing does not apply to 
    statements in or omissions from any such documents made in reliance upon 
    and in conformity with written information furnished to the Company by 
    any Agent specifically for use therein, or as to any statement in or 
    omission from the Statement of Eligibility and Qualification (Form T-1) 
    of the Trustee under the Indenture.  "Marketing Period" shall mean any 
    time when no suspension of solicitation of offers to purchase Notes 
    pursuant to Sections 2(b) and 3(c) hereof shall be in effect and at any 
    time when any Agent shall own any Notes purchased by such Agent from the 
    Company with the intention of reselling them for a period not to exceed 
    ninety (90) days after the delivery of, and payment for, such Notes or 
    the Company has accepted an offer to purchase Notes but the related 
    settlement has not occurred.

<PAGE>

         (d)  The Incorporated Documents complied when filed with the 
    Commission, comply and will comply at all times during each Marketing 
    Period, in all material respects with the applicable provisions of the 
    Act, the Securities Exchange Act of 1934, as amended (the "Exchange 
    Act"), and the Trust Indenture Act of 1939, as amended (the "Trust 
    Indenture Act"), and, when read together and with the other information 
    in the Registration Statement or Prospectus, did not, do not and will not 
    contain any untrue statement of a material fact and did not, do not and 
    will not omit to state a material fact required to be stated therein or 
    necessary to make the statements therein, in light of the circumstances 
    under which they were or are made, not misleading, except that the 
    foregoing does not apply to statements in or omissions from any such 
    documents made in reliance upon and in conformity with written 
    information furnished to the Company by any Agent specifically for use 
    therein.  All references to the Exchange Act or the Trust Indenture Act 
    shall include the rules and regulations of the Commission promulgated 
    thereunder.  The Incorporated Documents have been and will be at all 
    times during each Marketing Period timely filed as required by the 
    Exchange Act.  There are no contracts or documents of the Company or any 
    subsidiary of the Company which are required to be filed as exhibits to 
    the Registration Statement which have not been filed as required.

         (e)  Subsequent to the respective dates as of which information is 
    given in the Registration Statement and the Prospectus, except as 
    contemplated in the Prospectus, there has not been any material adverse 
    change in the condition (financial or other), net worth or results of 
    operations of the Company and the subsidiaries considered as one 
    enterprise.

         (f)  The financial statements in the Registration Statement and the 
    Prospectus fairly present and will fairly present at all times during 
    each Marketing Period the financial condition of the Company and the 
    results of its operations; and said financial statements (including the 
    related notes) have been and will be at all times during each Marketing 
    Period prepared in accordance with generally accepted accounting 
    principles consistently applied throughout the periods involved (except 
    for any changes in which the independent accountants for the Company have 
    concurred and which have been specifically disclosed to the Agents).

         (g)  The outside auditors whose report appears in the Company's most 
    recent Annual Report on Form 10-K of the Company are independent public 
    accountants as required by the Act.

                                    4

         (h)  Prior to each issuance and sale of Notes, the Company will have 
    full corporate power and lawful corporate authority to authorize, issue 
    and sell the Notes being issued and sold at that time, on the terms and 
    conditions set forth herein, and has taken or will take all corporate 
    action necessary therefor; the Company has obtained every consent, 
    approval, authorization or other order of any regulatory body which is 
    required for such authorization, issue or sale except as may be required 
    under the Act or state securities laws; and, when duly and validly 
    executed, authenticated and issued as provided in the Indenture and 
    delivered pursuant to this Agreement and the Indenture, the Notes will 
    constitute valid, legal and binding obligations of the Company 
    enforceable against it in accordance with their respective terms and the 
    terms of the Indenture and entitled to the benefits of the Indenture, 
    except as enforcement thereof may be limited by bankruptcy, insolvency, 
    or other similar laws relating to or affecting enforcement of creditors' 
    rights generally or by general equity principles.  The Indenture conforms 
    and the Notes will conform in all material respects to all statements in 
    relation thereto contained in the Registration Statement and the 
    Prospectus.  The Indenture has been duly authorized, executed and 
    delivered by the Company and constitutes a valid, legal and binding 
    instrument of the Company enforceable against the Company in accordance 
    with its terms, except as enforcement thereof may be limited by 
    bankruptcy, insolvency, or other similar laws relating to or affecting 
    enforcement of creditors' rights generally or by general equity 
    principles.  The Indenture has been duly qualified under the Trust 
    Indenture Act.

         (i)  Except as set forth in the Prospectus, the Company is not in 
    violation of its Articles of Incorporation or by-laws or in default under 
    any agreement, indenture or instrument, the effect of which violation or 
    default would be materially adverse to the condition (financial or 
    other), net worth or results of operations of the Company.  The 
    performance by the Company of its obligations under this Agreement and 
    any applicable Purchase Agreement and the consummation of the 
    transactions contemplated herein and therein and the fulfillment of the 
    terms hereof and thereof and execution and delivery by the Company of, 
    and the compliance by the Company with, all the terms and provisions of 
    the Notes and the Indenture will not result in a breach or violation of 
    any of the terms or provisions of, or constitute a default under, any 
    statute, indenture, mortgage, deed of trust, note agreement or other 
    material agreement or instrument to which the Company or any of its 
    subsidiaries is a party, or by which they or any of their property is 
    bound, or the Articles of Incorporation or by-laws of the Company or any 
    of its subsidiaries or any order, rule or regulation applicable to the 
    Company or any of its subsidiaries of any court or of any federal or 
    state regulatory body or administrative agency or other governmental body 
    having jurisdiction over the Company or any of its subsidiaries or their 
    respective or collective property.

         (j)  Except as set forth in the Prospectus, there is no pending 
    action, suit or other proceeding to which the Company is a party or of 
    which any property of the Company or any of its subsidiaries is the 
    subject, before or by any court or other governmental body, which is 
    likely to result in any material adverse change in the condition 
    (financial or other), net worth or results of operations of the Company 
    and its subsidiaries considered as one enterprise; and, except as set 
    forth in the Prospectus, no such action, suit or proceeding is known by 
    the Company to be threatened or contemplated.

                                    5

<PAGE>

         (k)  The certificates delivered pursuant to Section 5(h) hereof and 
    all other documents delivered by the Company or its representatives in 
    connection with the issuance and sale of the Notes were on the dates on 
    which they were delivered in all material respects true and complete.

         (l)  Each of this Agreement and any applicable written Purchase 
    Agreement has been or will be duly and validly authorized, executed and 
    delivered by the Company and, upon execution and delivery by the Agents 
    and subject to any principles of public policy limiting the right to 
    enforce the indemnification provisions contained herein, will be a valid 
    and binding agreement of the Company.

         (m)  Each of the Mortgage Indenture and the Thirty-fifth 
    Supplemental Indenture has been duly authorized, executed and delivered 
    by the Company and is a legal, valid and binding obligation of the 
    Company enforceable against the Company in accordance with its terms, 
    except as enforcement thereof may be limited by bankruptcy, insolvency, 
    or other similar laws relating to or affecting enforcement of creditors' 
    rights generally or by general equity principles.  The Mortgage Indenture 
    has been qualified under the Trust Indenture Act.

         (n)  The Company has good and sufficient title to all the properties 
    described as owned by it in, and subject to the lien of, the Mortgage 
    Indenture (the "Mortgage Properties"), subject only to Permitted Liens 
    (as defined in the Mortgage Indenture), and to minor defects and 
    irregularities customarily found in properties of like size and character 
    that do not materially impair the use of the property affected thereby in 
    the operation of the business of the Company; the descriptions in the 
    Mortgage Indenture of the Mortgage Properties are adequate to constitute 
    the Mortgage Indenture a lien thereon; and the Mortgage Indenture 
    constitutes a valid lien on the Mortgage Properties, which include 
    substantially all of the permanent physical properties and franchises of 
    the Company (other than those expressly excepted), subject only to the 
    exceptions enumerated above.

         (o)  The Mortgage Bonds deposited with the Trustee as the basis for 
    the issuance of the Notes have, to the extent that such Mortgage Bonds 
    have been designated by the Company as designated mortgage bonds (the 
    "Designated Mortgage Bonds"), been duly pledged to the Trustee, and the 
    Indenture will, upon payment for the Notes issued upon the basis of the 
    Designated Mortgage Bonds so deposited, constitute a valid first lien 
    thereupon; no registration, recording or filing of the Indenture (or 
    notices or financing statements in respect thereof) is required by law to 
    make effective and to maintain the lien on the Designated Mortgage Bonds 
    so deposited intended to be created by the Indenture.

                                    6

<PAGE>

         (p)  The Company has full corporate power and lawful corporate 
    authority to authorize, issue and pledge the Mortgage Bonds and has taken 
    or will take all corporate action necessary therefor; the Company has 
    obtained every consent, approval, authorization or other order of any 
    regulatory body which is required for such authorization, issue or 
    pledge. The Mortgage Indenture and the Mortgage Bonds conform in all 
    material respects to all statements in relation thereto contained in the 
    Registration Statement and the Prospectus.

         (q)  The Mortgage Bonds deposited with the Trustee and the 
    Designated Mortgage Bonds pledged to the Trustee as the basis for the 
    issuance of the Securities constitute legal, valid and binding 
    obligations of the Company, subject, as to enforcement, to laws relating 
    to or affecting generally the enforcement of creditors' rights, 
    including, without limitation, bankruptcy and insolvency laws, and to 
    general principles of equity, and will be entitled to the security 
    afforded by the Mortgage Indenture equally and ratably with the 
    securities outstanding thereunder.

         (r)  The Company is not an "investment company" or an entity 
    "controlled" by an "investment company" as such terms are defined in the 
    Investment Company Act of 1940, as amended.

    SECTION 2.  Solicitations as Agent; Purchases as Principal. 

    (a)  Appointment.  Subject to the terms and conditions stated herein, 
including, without limitation, the provisions of Section 11 hereof, the 
Company hereby appoints each of the Agents as the co-exclusive agents of the 
Company for the purpose of soliciting or receiving offers to purchase the 
Notes from the Company by others during any Marketing Period.  On the basis 
of the representations and warranties contained herein, but subject to the 
terms and conditions herein set forth, each Agent agrees, as a co-exclusive 
agent of the Company, to use its reasonable best efforts to solicit offers to 
purchase the Notes upon the terms and conditions set forth in the Prospectus. 
 The Agents are not authorized to appoint sub-agents or to engage the 
services of any other broker or dealer in connection with the offer or sale 
of the Notes, except as provided in paragraph (e) of this Section.  Except as 
otherwise provided herein, including, without limitation, the provisions of 
Section 11 hereof, so long as this Agreement shall remain in effect with 
respect to any Agent, the Company shall not, without the consent of each such 
Agent (which consent shall not unreasonably be withheld), solicit or accept 
offers to purchase Notes otherwise than through one of the Agents, PROVIDED,
HOWEVER, the Company expressly reserves the right to sell Notes directly to 
investors, in which case no commission will be payable with respect to such 
sale.  Each Agent may also purchase Notes from the Company as principal for 
purposes of resale, as more fully described in paragraph (e) of this Section. 

    (b)  Suspension of Solicitation.  The Company reserves the right, in its 
sole discretion, to suspend solicitation of offers to purchase the Notes 
commencing at any time for any period  of time or indefinitely.  As soon as 
practicable, but in any event not later than one business day after receipt 
of notice from the Company, the Agents will forthwith suspend solicitation of 
offers to purchase Notes from the Company until such time as the Company has 
advised the Agents that such solicitation may be resumed.

                                    7

For the purpose of the foregoing sentence, "business day" shall mean any day 
which is not a Saturday or Sunday and which is not a day on which (i) banking 
institutions are generally authorized or obligated by law to close in the 
City of New York or (ii) The New York Stock Exchange is closed for trading.

    Upon receipt of notice from the Company as contemplated by Section 3(b) 
hereof, each Agent shall suspend its solicitation of offers to purchase Notes 
until such time as the Company shall have furnished it with an amendment or 
supplement to the Registration Statement or the Prospectus, as the case may 
be, contemplated by Section 3(c) and shall have advised such Agent that such 
solicitation may be resumed.

    (c)  Agent's Commission.  Upon the closing of the sale of any Notes sold 
by the Company as a result of a solicitation made by or offer to purchase 
received by an Agent, the Company agrees to pay such Agent a commission in 
accordance with the schedule set forth in Exhibit B hereto.

    (d)  Solicitation of Offers.  The Agents are authorized to solicit offers 
to purchase the Notes only in the denominations specified in the Prospectus, 
at a purchase price equal to 100% of the principal amount thereof or such 
other principal amount or purchase price as shall be specified by the 
Company.  Each Agent shall communicate to the Company, orally or in writing, 
each reasonable offer to purchase Notes received by it as an Agent.  The 
Company shall have the sole right to accept offers to purchase the Notes and 
may reject any  offer in whole or in part.  Each Agent shall have the right, 
in its discretion reasonably exercised, to reject any offer to purchase the 
Notes received by it, without advising the Company, in whole or in part, and 
any such rejection shall not be deemed a breach of its agreement contained 
herein.

    No Note which the Company has agreed to sell pursuant to this Agreement 
shall be deemed to have been purchased and paid for, or sold by the Company, 
until such Note shall have been delivered to the purchaser thereof against 
payment therefor by such purchaser.

    (e)  Purchases as Principal.  Each sale of Notes to any Agent as 
principal, for resale to one or more investors or to another broker-dealer 
(acting as principal for purposes of resale), shall be made in accordance 
with the terms of this Agreement and a Purchase Agreement, whether oral (and 
confirmed in writing by such Agent to the Company, which may be by facsimile 
transmission) or in writing, which will provide for the sale of such Notes 
to, and the purchase thereof by, such Agent.  A Purchase Agreement may also 
specify certain provisions relating to the reoffering of such Notes by such 
Agent.  The commitment of any Agent to purchase Notes from the Company  as 
principal shall be deemed to have been made on the basis of the 
representations and warranties of the Company herein contained and shall be 
subject to the terms and conditions herein set forth.  Each Purchase 
Agreement shall specify the principal amount and terms of the Notes to be 
purchased by an Agent, the time and date (each such time and date being 
referred to herein as a "Time of Delivery") and place of delivery of and 
payment for such Notes and such other information (as applicable) as is set 
forth in Exhibit A hereto.

                                    8

The Company agrees that if any Agent purchases Notes as principal for resale 
such Agent shall receive such compensation, in the form of a discount or 
otherwise, as shall be indicated in the applicable Purchase Agreement or, if 
no compensation is indicated therein, a commission in accordance with Exhibit 
B hereto.  Any Agent may utilize a selling or dealer group in connection with 
the resale of such Notes.  In addition, any Agent may offer the Notes it has 
purchased as principal to other dealers.  Any Agent may sell Notes to any 
dealer at a discount and, unless otherwise specified in the applicable 
Pricing Supplement (as such term is defined in Section 3(a) hereof), such 
discount allowed to any dealer will not be in excess of the discount to be 
received by such Agent from the Company.  Such Purchase Agreement shall also 
specify any requirements for delivery of opinions of counsel, accountant's 
letters and officers' certificates pursuant to Section 5 hereof.

    The obligation of the Company to sell and deliver Notes, pursuant to any 
Purchase Agreement or otherwise, shall in each case be subject to the 
condition that, on any settlement date for the sale of Notes or the Time of 
Delivery, as the case may be, no stop order suspending the effectiveness of 
the Registration Statement shall have been issued and still be in effect and 
no proceedings for that purpose shall be pending before, or to the knowledge 
of the Company or the Agents contemplated or threatened by, the Commission.  
Each date of delivery of and payment for Notes to be purchased by an Agent 
pursuant to a Purchase Agreement is referred to herein as a "Settlement Date."

    (f)  Administrative Procedures.  Administrative procedures respecting the 
sale of Notes (the "Procedures") are set forth in Exhibit C hereto and may be 
amended from time to time in writing signed by each of the Agents and the 
Company.  Each Agent and the Company agree to perform the respective duties 
and obligations specifically provided to be performed by each of them herein 
and in the Procedures.  The Procedures shall apply to all transactions 
contemplated hereunder including sales of Notes to any Agent as principal 
pursuant to a Purchase Agreement, unless otherwise set forth in such Purchase 
Agreement.

    (g)  Delivery of Documents.  The documents required to be delivered by 
Section 5 hereof shall be delivered at the offices of Ropes & Gray not later 
than 10:00 a.m., Boston time, on the date of this Agreement or at such later 
time as may be mutually agreed upon by the Company and the Agents, which in 
no event shall be later than the time at which the Agents commence 
solicitation of offers to purchase Notes hereunder.  The date of delivery of 
such documents is referred to herein as the "Commencement Date."

    (h)  Obligations Several.  The Company acknowledges that the obligations 
of the Agents under this Agreement are several and not joint.

    SECTION 3.  Covenants of the Company.  The Company covenants and agrees 
with each of the Agents, as follows:

                                    9

<PAGE>

         (a)  Amendments and Supplements to Registration Statement and 
    Prospectus.  The Company will give the Agents notice of its intention to 
    file any amendment to the Registration Statement or amendment or 
    supplement to the Prospectus (other than a supplement providing solely 
    for the specification of the interest rates, maturity dates, issuance 
    prices, redemption terms and prices, if any, and other terms of Notes 
    sold pursuant hereto (any such supplement being hereinafter called a 
    "Pricing Supplement")), whether by the filing of documents pursuant to 
    the Act, the Exchange Act or otherwise, and will furnish the Agents with 
    copies of any such amendment or supplement or other documents proposed to 
    be filed a reasonable time in advance of such proposed filing.

         (b)  Notice to Agents of Certain Events.  The Company will notify 
    each of the Agents immediately, and confirm in writing if requested by 
    the Agents in any particular instance, (i) when any amendment or 
    post-effective amendment to the Registration Statement has been filed 
    and/or becomes effective or when any supplement or amendment to the 
    Prospectus has been filed, (ii) of the issuance of any stop order 
    suspending the effectiveness of the Registration Statement or of any 
    order preventing or suspending the use of any preliminary prospectus 
    relating to the Notes or the Prospectus or of the initiation or 
    threatening known by it of any proceedings for such purposes, (iii) of 
    the receipt of any comments from the Commission in respect of the 
    Registration Statement, any such preliminary prospectus or the 
    Prospectus, or requesting the amendment or supplementation of the 
    Registration Statement, any such preliminary prospectus or the Prospectus 
    or additional information, (iv) of any action by any governmental 
    authority altering, suspending or otherwise affecting any authorization, 
    consent, approval or waiver issued in connection with the Notes and (v) 
    of the commencement of any litigation or administrative proceeding 
    relating to the issue and sale of the Notes.  If the Commission shall 
    enter a stop order or any order preventing or suspending the use of any 
    such preliminary prospectus or the Prospectus at any time, or shall 
    initiate any proceedings for such purposes, the Company will make every 
    reasonable effort to prevent the issuance of such order and, if issued, 
    to obtain the lifting thereof. If the Prospectus is amended or 
    supplemented as a result of the filing under the Exchange Act of any 
    document incorporated by reference in the Prospectus, no Agent shall be 
    obligated to solicit offers to purchase Notes so long as it is not 
    reasonably satisfied with such documents.

         (c)  Revisions to Prospectus or Registration Statement.  During any 
    Marketing Period, the Company will comply with all requirements imposed 
    upon it by the Act and the Exchange Act, as now and hereafter amended, as 
    from time to time in force, so far as necessary to permit the continuance 
    of sales of or dealings in the Notes as contemplated by the provisions 
    hereof and the Prospectus; and if during any Marketing Period any event 
    occurs or condition exists as a result of which the Prospectus as then 
    amended or supplemented would include an untrue statement of a material 
    fact or omit to state any material fact necessary to make the statements 
    therein, in light of the circumstances then existing, not misleading, or 
    if, in the opinion of the Agents (of which opinion such Agents shall 
    immediately notify the Company by telephone with confirmation in writing) 
    or in the opinion of the Company, during such period it is necessary to 
    amend or supplement the Registration Statement or the Prospectus, as then 
    amended or supplemented, to comply in all material respects with the Act 
    or the Exchange Act, the Company will immediately notify each of the 
    Agents by telephone (with confirmation in writing) to suspend 
    solicitation of offers to purchase Notes and, if so notified by the 
    Company, the Agents shall forthwith suspend such solicitation and cease 
    using the Prospectus, as then amended or supplemented.

                                   10

<PAGE>

    If the Company shall decide to amend or supplement the Registration 
    Statement or Prospectus, as then amended or supplemented, it shall so 
    advise the Agents promptly by telephone (with confirmation in writing) 
    and, at its expense, shall prepare and cause to be filed promptly with 
    the Commission an amendment or supplement to the Registration Statement 
    or Prospectus, as then amended or supplemented, that will correct such 
    statement or omission or effect such compliance and will supply such 
    amended or supplemented Prospectus to the Agents in such quantities as 
    they may reasonably request.  If any documents, certificates, opinions 
    and letters furnished to the Agents pursuant to Sections 6(b), 6(c) and 
    6(d) in connection with the preparation and filing of such amendment or 
    supplement are satisfactory in all respects to the Agents, upon the 
    filing with the Commission of such amendment or supplement to the 
    Prospectus or upon the effectiveness of an amendment to the Registration 
    Statement, the Agents will resume the solicitation of offers to purchase 
    Notes hereunder.  Notwithstanding any other provision of this Section 
    3(c), until the distribution of any Notes an Agent may own as principal 
    has been completed, if any event described above in this paragraph (c) 
    occurs, the Company will, at its own expense, forthwith prepare and cause 
    to be filed promptly with the Commission an amendment or supplement to 
    the Registration Statement or Prospectus, as then amended or 
    supplemented, satisfactory in all respects to such Agent, will supply 
    such amended or supplemented Prospectus to such Agent in such quantities 
    as it may reasonably request and shall furnish to such Agent pursuant to 
    Sections 6(b), 6(c) and 6(d) such documents, certificates, opinions and 
    letters as it may request in connection with the preparation and filing 
    of such amendment or supplement; provided that should such event 
    described above in this paragraph (c) relate solely to activities of any 
    Agent or Agents, then such Agent or Agents, as the case may be, shall 
    assume the expense of preparing and furnishing any such amendment or 
    supplement.

         (d)  Earning Statement.  As soon as practicable the Company will 
    make generally available to its security holders and deliver to each of 
    the Agents an earning statement which shall satisfy the provisions of 
    Section 11(a) of the Act and the rules and regulations of the Commission 
    thereunder, including Rule 158 issued thereunder.

         (e)  Delivery of Signed Registration Statement and Other Documents.  
    The Company will deliver to each of the Agents and to counsel for the 
    Agents without charge as promptly as practicable a signed copy of the 
    Registration Statement and all amendments thereto including all exhibits 
    filed therewith and signed consents, certificates and opinions of 
    accountants and of any other persons named in the Registration Statement 
    as having prepared, certified or reviewed any part thereof, and will 
    deliver to the Agents without charge such number of unsigned copies of 
    the Registration Statement, without exhibits, and of all amendments 
    thereto, as the Agents may reasonably request.  The Company will deliver 
    to or upon order of the Agents without charge as many copies of each 
    preliminary prospectus relating to the Notes as the Agents may reasonably 
    request and as many copies of the Prospectus in final form, or as 
    thereafter amended or supplemented, as the Agents may reasonably request.

                                    11

<PAGE>

         (f)  Blue Sky Qualifications.  The Company will cooperate with the 
    Agents in connection with the qualification of the Notes for sale under 
    the securities laws of such jurisdictions as the Agents may reasonably 
    designate and the continuance of such qualifications in effect so long as 
    required for the distribution of the Notes, provided that the Company 
    shall not be required to qualify as a foreign corporation in any 
    jurisdiction in which it is not so qualified or to submit to any 
    requirement which it deems unduly burdensome.  The Company will advise 
    each of the Agents promptly of any order or communication of any public 
    authority addressed to the Company suspending or threatening to suspend 
    the qualification of the Notes for sale, or the eligibility of the Notes 
    for purchase by such institutions, in any jurisdiction.

         (g)  Copies of Reports and Financial Statements.  For the period 
    ending five years from the Commencement Date, the Company will deliver to 
    each of the Agents (i) as soon as available, a copy of each report of the 
    Company mailed to public security holders or filed with the Commission 
    and (ii) such additional information concerning the business and 
    financial condition of the Company as such agent may from time to time 
    reasonably request (such financial statements to be on a consolidated 
    basis to the extent the accounts of the Company and its subsidiaries are 
    consolidated in reports furnished to its stockholders generally or to the 
    Commission).

         (h)  Application of Net Proceeds.  The Company will apply the net 
    proceeds from the sale of the Notes for the purposes set forth in the 
    Prospectus.

         (i)  Suspension of Certain Obligations.  The Company shall not be 
    required to comply with the provisions of paragraphs (c) or (g) of this 
    Section 3 during any Marketing Period from the time the Agents shall have 
    suspended solicitation of purchases of the Notes in their capacity as 
    agents pursuant to a request from the Company pursuant to Section 2(b) 
    hereof to the time the Company shall determine that solicitation of 
    purchases of the Notes should be resumed or shall subsequently enter into 
    a new Purchase Agreement with an Agent, PROVIDED, HOWEVER, that 
    compliance with such paragraphs shall be required for any portion of such 
    period during which any Agent shall hold any Notes as principal purchased 
    pursuant to the Purchase Agreement.

         (j)  Downgrading.  The Company shall notify the Agents promptly in 
    writing of any downgrading, or its receipt of any notice of any intended 
    or potential downgrading or of any review for possible change that does 
    not indicate the direction of the possible change, in the rating accorded 
    any of the Company's securities by any "nationally recognized statistical 
    rating organization," as such term is defined for purposes of Rule 
    436(g)(2) under the Act.

                                   12

<PAGE>

         (k)  During the period beginning the date of any Purchase Agreement 
    and continuing to and including the Settlement Date with respect to such 
    Purchase Agreement, the Company will not, without such Agent's prior 
    written consent, offer, sell, contract to sell or otherwise dispose of 
    any debt securities of the Company or warrants to purchase debt 
    securities of the Company substantially similar to such Notes (other than 
    (i) Notes that are to be sold pursuant to such Purchase Agreement, (ii) 
    Notes previously agreed to be sold by the Company and (iii) commercial 
    paper issued in the ordinary course of business), except as may otherwise 
    be provided in such Purchase Agreement.

    SECTION 4.  Payment of Expenses.  The Company will pay (i) the costs 
incident to the authorization, issuance, sale and delivery of the Notes and 
any taxes payable in connection therewith, (ii) the costs incident to the 
preparation, printing and filing under the Act of the Registration Statement 
and any amendments and exhibits thereto and the Prospectus and any amendments 
and supplements thereto, (iii) the costs incident to the preparation, 
printing and filing of any document and any amendments and exhibits thereto 
required to be filed by the Company under the Exchange Act, (iv) the costs of 
distributing the Registration Statement, as originally filed, and each 
amendment and post-effective amendment thereof (including exhibits), any 
preliminary prospectus, the Prospectus, any supplement or amendment to the 
Prospectus and any documents incorporated by reference in any of the 
foregoing documents, (v) the costs and expenses incident to the preparation, 
execution and delivery of the Indenture and the Supplemental Indenture, (vi) 
the fees and disbursements of the Trustee, any paying agent, any calculation

Memorandum, (xii) all advertising expenses in connection with the offering of

out-of-pocket expenses incurred by the Agents in connection with the

Company in connection with a "road show" presentation to potential investors 
and (xv) other costs and expenses incident to the performance of the 
Company's obligations under this Agreement.

    SECTION 5.  Conditions of Obligations of Agents.  The obligation of the 
Agents, as the agents of the Company, under this Agreement to solicit offers 
to purchase the Notes, the obligation of any person who has agreed to 
purchase Notes to make payment for and take delivery of Notes, and the 
obligation of any Agent to purchase Notes pursuant to any Purchase Agreement, 
is subject to the accuracy, on each Settlement Date and in the case of an 
Agent's obligation to solicit offers to purchase Notes, at the time of such 
solicitation, of the representations and warranties of the Company contained 
herein, to the accuracy of the statements of the Company's officers made in 
any certificate furnished pursuant to the provisions hereof, to the 
performance by the Company of its obligations hereunder, and to each of the 
following additional terms and conditions:

                                   13

<PAGE>

         (a)  Registration Statement.  The Registration Statement shall have 
    become effective under the Act and the Indenture shall have been 
    qualified under the Trust Indenture Act, and no stop order suspending the 
    effectiveness of the Registration Statement or the qualification of the 
    Indenture, or order preventing or suspending the use of any Prospectus, 
    shall have been issued and no proceeding for that purpose shall have been 
    initiated or, to the knowledge of the Company or the Agents, contemplated 
    or threatened by the Commission; any request for additional information 
    on the part of the Commission (to be included in the Registration 
    Statement or the Prospectus or otherwise) shall have been complied with; 
    and no amendment to the Registration Statement or Prospectus shall have 
    been filed to which the Agents shall have reasonably objected, in 
    writing, after having received notice pursuant to Section 3(a).

         (b)  Regulatory Approvals. There shall be in full force and effect 
    appropriate orders or decrees of the Public Service Commission of Nevada 
    and the California Public Utilities Commission (or such other regulatory 
    bodies as may subsequently have jurisdiction) authorizing to the extent 
    required by law the offering, issuance and sale of the Notes as herein 
    provided.  Any such decision, order or decree issued after the date 
    hereof shall contain no condition inconsistent with the provisions hereof 
    or reasonably unacceptable to the Agents (it being understood and agreed 
    that no such order or decree in effect on the date of this Agreement 
    contains any such unacceptable provision). 

         (c)  Absence of Certain Changes.  Subsequent to the respective dates 
    as of which information is given in the Registration Statement and the 
    Prospectus, there shall not have been any downgrading nor shall any 
    notice have been given of any intended or potential downgrading or of any 
    review for possible change that does not indicate the direction of the 
    possible change, in the ratings accorded the Company's debt securities by 
    Moody's Investors Service, Inc., Standard and Poor's Corporation or Duff 
    & Phelps, Inc., or, except as contemplated in the Prospectus, any change 
    in the capital stock, short-term debt or long-term debt of the Company, 
    or any adverse change or any development involving a prospective adverse 
    change in the condition (financial or other), net worth or results of 
    operations of the Company and its subsidiaries, considered as one 
    enterprise, which, in any such event, in the Agents' judgment, is 
    material and adverse and that makes it, in the judgment of such Agents, 
    impracticable to market the Notes on the terms and in the manner 
    contemplated by the Prospectus, as so amended or supplemented, or 
    materially impairs the investment quality of the Notes.

         (d)  Legal Matters Satisfactory to Counsel.  The authorization and 
    issuance of the Notes, the Indenture, the Mortgage Indenture, the 
    Mortgage Bonds, the Registration Statement, the Prospectus and all 
    corporate proceedings and other legal matters incident thereto shall be 
    satisfactory in all respects to counsel for the Agents, and the Company 
    shall have furnished to counsel for the Agents such documents as they may 
    reasonably request to enable them to be satisfied with respect to the 
    matters referred to in this subparagraph and to pass upon such matters.

         (f)  Opinion of Woodburn and Wedge.  On the Commencement Date, the 
    Agents shall have received the opinion, addressed to the Agents and dated 
    the Commencement Date, of Woodburn and Wedge, counsel for the Company in 
    the state of Nevada, in the form set forth in Exhibit E to this Agreement.

    the Commencement Date, of Graham & James LLP, counsel for the Company in 
    the State of California, in the form set forth in Exhibit F to this 
    Agreement.

         (h)  Officers' Certificate.  The Company shall have furnished to the 
    Agents on the Commencement Date a certificate, dated the Commencement 
    Date as though made at and as of the Commencement Date, of its President 
    or a Vice President and of a principal financial or accounting officer of 
    the Company, covering the matters set forth in Exhibit G to this 
    Agreement.

         (i)  Accountants' Letters.  The Company shall have furnished to the 
    Agents on the Commencement Date a letter from its independent 
    accountants, addressed jointly to the Company and the Agents and dated 
    the Commencement Date, of the type described in the American Institute of 
    Certified Public Accountants Statement on Auditing Standards No. 72, 
    covering specified financial statement items and procedures set forth in 
    Exhibit H to this Agreement. 

         (j)  Additional Conditions.  There shall not have occurred:  a 
    suspension or material limitation in trading in securities generally on 
    or by the New York Stock Exchange, the American Stock Exchange or the 
    over-the-counter market or the establishment of minimum prices on such 
    exchanges or market by the Commission, by such exchange or by any other 
    regulatory body or governmental authority having jurisdiction; suspension 
    of trading of any securities of the Company on any exchange or in any 
    over-the-counter market; a general moratorium on commercial banking 
    activities declared by either Federal or New York State authorities; any 
    outbreak or escalation of major hostilities in which the United States is 
    involved, any declaration of war by Congress or any other substantial 
    national calamity or emergency; if the effect of any such occurrence in 
    the judgment of the Agents makes it impracticable or inadvisable to 
    proceed with the solicitation of offers to purchase Notes or the purchase 
    of Notes from the Company as principal pursuant to the applicable 
    Purchase Agreement, as the case may be, on the terms and in the manner 
    contemplated by the Prospectus, as amended or supplemented.

                                   15

<PAGE>

         (k)  Opinion of Ropes & Gray.  At the Commencement Date, the Agent 
    shall have received the opinion, addressed to the Agents and dated the

    substance satisfactory to the Agents with respect to the incorporation of 
    the Company, the validity of the Notes, the Registration Statement, the 
    Prospectus and other related matters as they may require, and the Company 
    shall have furnished to such counsel such documents as the Agents may 
    reasonably request for the purpose of enabling them to pass upon such 
    matters.

         (l)  Other Information and Documentation.  Prior to the Commencement 
    Date, the Company shall have furnished to the Agents such further 
    information, certificates and documents as the Agents or counsel for the 
    Agents may have reasonably requested.

    Ropes & Gray and Choate, Hall & Stewart, in giving their opinions 
pursuant to this Section 5, may rely upon the opinion of Graham & James LLP 
as to all legal conclusions affected by the laws of California, and upon the 
opinion of Woodburn and Wedge as to all legal conclusions affected by the 
laws of Nevada.

    SECTION 6.  Additional Covenants of the Company. The Company covenants 
and agrees that:

         (a)  Acceptance of Offer Affirms Representations and Warranties.  
    Each acceptance by it of an offer for the purchase of Notes shall be 
    deemed to be an affirmation that the representations and warranties of 
    the Company contained in this Agreement and in any certificate 
    theretofore given to the Agents pursuant hereto are true and correct at 
    the time of such acceptance, and an undertaking that such representations 
    and warranties will be true and correct at the time of delivery to the 
    purchaser or his agent of the Notes relating to such acceptance as though 
    made at and as of each such time (and such representations and warranties 
    shall relate to the Registration Statement and the Prospectus as amended 
    or supplemented to each such time).


         (b)  Subsequent Delivery of Officers' Certificates.  The Company 
    agrees that during each Marketing Period, each time that the Registration 
    Statement or the Prospectus shall be amended or supplemented (other than 
    by a Pricing Supplement), each time the Company sells Notes to an Agent 
    as principal and the applicable Purchase Agreement specifies the delivery 
    of an officers' certificate under this Section 6(b) as a condition to the 
    purchase of Notes pursuant to such Purchase Agreement and each time the 
    Company files with the Commission any document incorporated by reference 
    into the Prospectus (other than any Current Report on Form 8-K unless an 
    Agent shall otherwise reasonably request), the Company shall submit to 
    the Agents and their counsel a certificate of the President or Vice 
    President or a principal financial or accounting officer of the Company, 
    (i) as of the date of such amendment, supplement and Time of Delivery

                                   16

<PAGE>

    relating to such sale or filing or (ii) if such amendment, supplement or 
    filing was not filed during a Marketing Period, as of the first day of 
    the next succeeding Marketing Period, representing that the statements 
    contained in the certificate referred to in Section 5(h) hereof which was 
    last furnished to the Agents are true and correct at the time of such 
    amendment, supplement or filing, as the case may be, as though made at 
    and as of such time (except that such statements shall be deemed to 
    relate to the Registration Statement and the Prospectus as amended and 
    supplemented at such time) or, in lieu of such certificate, a certificate 
    of the same tenor as the certificate referred to in said Section 5(h), 
    modified as necessary to relate to the Registration Statement and the 
    Prospectus as amended and supplemented to the time of delivery of such 
    certificate.

         (c)  Subsequent Delivery of Legal Opinions.  The Company agrees that 
    during each Marketing Period, each time that the Registration Statement 
    or the Prospectus shall be amended or supplemented (other than by a 
    Pricing Supplement), each time the Company sells Notes to an Agent as 
    principal and the applicable Purchase Agreement specifies the delivery of 
    legal opinions under this Section 6(c) as a condition to the purchase of 
    Notes pursuant to such Purchase Agreement and each time the Company files 
    with the Commission any document incorporated by reference into the 
    Prospectus (other than any Current Report on Form 8-K unless an agent 
    shall otherwise reasonably request), the Company shall (i) concurrently 
    with such amendment, supplement and Time of Delivery relating to such 
    sale or filing or (ii) if such amendment, supplement or filing was not 
    filed during a Marketing Period, on the first day of the next succeeding 
    Marketing Period, furnish the Agents and their counsel with the written 
    opinions of counsel to the Company, addressed to the Agents and dated the 
    date of delivery of such opinion, in form satisfactory to the Agents, of 
    the same tenor as the opinions referred to in Sections 5(e), 5(f) and 
    5(g) hereof, respectively, but modified, as necessary, to relate to the 
    Registration Statement and the Prospectus as amended or supplemented to 
    the time of delivery of such opinion; PROVIDED, HOWEVER, that in lieu of 
    such opinions, such counsel may furnish the Agents and their counsel with 
    a letter to the effect that the Agents may rely on any prior opinion of 
    such counsel to the same extent as though it were dated the date of such 
    letter authorizing reliance (except that statements in such prior opinion 
    shall be deemed to relate to the Registration Statement and the 
    Prospectus as amended or supplemented to the time of delivery of such 
    letters authorizing reliance).

         (d)  Subsequent Delivery of Accountants' Letters.  The Company 
    agrees that during each Marketing Period, each time that the Registration 
    Statement or the Prospectus shall be amended or supplemented to include 
    additional financial information derived from the books and records of 
    the Company, each time the Company sells Notes to an Agent as principal 
    and the applicable Purchase Agreement specifies the delivery of letters 
    under this Section 6(d) as a condition to the purchase of Notes pursuant 
    to such Purchase Agreement and each time the Company files with the 
    Commission any document incorporated by reference into the Prospectus 
    which contains additional financial information derived from the books 
    and records of the Company, the Company shall cause the Company's 
    independent public accountants to furnish the Agents and their 

                                   17

<PAGE>

    counsel (i) concurrently with such amendment, supplement and Time of 
    Delivery relating to such sale or filing or (ii) if such amendment, 
    supplement or filing was not filed during a Marketing Period, on the 
    first day of the next succeeding Marketing Period, a letter, addressed 
    jointly to the Company and the Agents and dated the date of delivery of 
    such letter, in form and substance of the type described in the relevant 
    statements of auditing standards, currently American Institute of 
    Certified Public Accountants Statement on Auditing Standards No. 72, and 
    of the same tenor as the letters referred to in Section 5(i) hereof but 
    modified to relate to the Registration Statement and the Prospectus, as 
    amended and supplemented to the date of such letter, with such changes as 
    may be necessary to reflect changes in the financial statements and other 
    information derived from the accounting records of the Company; PROVIDED, 
    HOWEVER, that if the Registration Statement or the Prospectus is amended 
    or supplemented solely to include financial information as of and for a 
    fiscal quarter, said outside auditors may refer to their previously 
    issued letter, shall reaffirm all statements made in that letter and may 
    limit the scope of such additional letter to the unaudited consolidated 
    financial statements included in such amendment or supplement and certain 
    agreed procedures, if any, of the type described in the American 
    Institute of Certified Public Accountants Statement on Auditing Standards 
    No. 72, covering specified financial statement items and procedures set 
    forth in Exhibit H to this Agreement.

         (e)  Opinions on Settlement Date.  On any Settlement Date, the 
    Company shall, if requested by the Agent that solicited or received the 
    offer to purchase any Notes being delivered on such Settlement Date, 
    furnish such Agent and its counsel with the written opinions of counsel 
    to the Company, addressed to the Agents and dated such settlement date, 
    in form satisfactory to the Agents, of the same tenor as the opinions 
    referred to in Sections 5(e), 5(f) and 5(g) hereof, respectively, but 
    modified, as necessary, to relate to the Prospectus relating to the Notes 
    to be delivered on such settlement date; PROVIDED, HOWEVER, that in lieu 
    of such opinions, such counsel may furnish such Agent and its counsel 
    with a letter to the effect that such Agent may rely on any prior opinion 
    of such counsel to the same extent as though it were dated such 
    settlement date (except that statements in such prior opinion shall be 
    deemed to relate to the Registration Statement and the Prospectus as 
    amended or supplemented to the time of delivery of such letter 
    authorizing reliance).

    SECTION 7.     Indemnification and Contribution. 

         (a)  The Company will indemnify and hold harmless each Agent and 
    each person, if any, who controls such Agent within the meaning of the 
    Act or the Exchange Act from and against any losses, claims, damages or 
    liabilities and any action in respect thereof to which such Agent or such 
    controlling person may become subject, under the Act or otherwise, with 
    respect to the Notes, insofar as such losses, claims, damages, 
    liabilities or actions arise out of or are based upon any untrue 
    statement or alleged untrue statement of any material fact contained in 
    the Registration Statement, the Prospectus, or any amendment or 
    supplement thereto, or arise out of or are based upon the omission 

                                   18

<PAGE>

    or alleged omission to state therein a material fact required to be 
    stated therein or necessary to make the statements therein not 
    misleading, and will reimburse each Agent and each such controlling 
    person for any legal or other expenses reasonably incurred by such Agent 
    or such controlling person in connection with investigating or defending 
    against any such loss, claim, damage, liability or action; PROVIDED, 
    HOWEVER, that the Company will not be liable in any such case to the 
    extent that any such loss, claim, damage, liability or action arises out 
    of or is based upon any untrue statement or alleged untrue statement or 
    omission or alleged omission made in the Registration Statement, the 
    Prospectus, or such amendment or such supplement, in reliance upon and in 
    conformity with written information furnished to the Company by such 
    Agent specifically for use in the preparation thereof, or as to any 
    statement in or omission from the Statement of Eligibility and 
    Qualification (Form T-1) of the Trustee under the Indenture; and 
    provided, further, that, insofar as it relates to the Prospectus, the 
    indemnity agreement contained in this Section 7(a) shall not inure to the 
    benefit of any Agent or any person who controls such Agent on account of 
    any losses, claims, damages or liabilities (or actions in respect 
    thereof) arising from the sale of Notes by such Agent pursuant to a 
    Purchase Agreement to any person if a copy of the Prospectus, as amended 
    or supplemented, shall not have been sent or given to such person with or 
    prior to the written confirmation of the sale involved to the extent that 
    the Prospectus, as amended or supplemented, if so sent or delivered, 
    would have cured the defect in the Prospectus giving rise to such losses, 
    claims, damages, liabilities or actions in respect thereof; and provided, 
    further, that if, at any time after the date of filing the Prospectus or 
    any amendment or supplement to the Prospectus with the Commission, any 
    event shall have occurred as a result of which the Prospectus as then 
    amended or supplemented ("Current Prospectus") would include an untrue 
    statement of a material fact or omit to state a material fact necessary 
    in order to make the statements therein, in the light of the 
    circumstances under which they were made when such Prospectus is 
    delivered, not misleading, and if the Company shall have furnished to any 
    Agent copies of an amended Prospectus ("Amended Prospectus") or of a 
    supplement to be attached to or furnished with the Current Prospectus 
    ("Supplement"), to which the Agent shall not have objected pursuant to 
    Section 5(a) hereof, for delivery in connection with offers and sales of 
    the Notes, the indemnity agreement contained in this Section 7(a), 
    insofar as it relates to the Current Prospectus, shall not inure to the 
    benefit of such Agent on account of any losses, claims, damages, 
    liabilities or actions in respect thereof arising from the sale of Notes 
    by such Agent to any person subsequent to the time such copies have been 
    so furnished to such Agent, if a copy of the Amended Prospectus or the 
    Supplement, as the case may be, shall not have been sent or given to such 
    person with or prior to the written confirmation of the sale involved, to 
    the extent that the Amended Prospectus or the Supplement, if so sent or 
    delivered, would have cured the defect in the Current Prospectus giving 
    rise to such losses, claims, damages, liabilities or actions in respect 
    thereof.  This indemnity agreement will be in addition to any liability 
    which the Company may otherwise have.  

                                   19

<PAGE>

         (b)  Each Agent agrees, severally and not jointly, to indemnify and 
    hold harmless the Company, each of its directors, each of its officers 
    who has signed the Registration Statement and each person, if any, who 
    controls the Company within the meaning of the Act or the Exchange Act, 
    against any losses, claims, damages or liabilities and any action in 
    respect thereof to which the Company or any such director, officer or 
    controlling person may become subject, under the Act or otherwise, 
    insofar as such losses, claims, damages, liabilities or actions arise out 
    of or are based upon (i) any untrue statement or alleged untrue statement 
    of any material fact contained in the Registration Statement, the 
    Prospectus, or any amendment or supplement thereto, or arise out of or 
    are based upon the omission or alleged omission to state therein a 
    material fact required to be stated therein or necessary to make the 
    statements therein not misleading, in each case to the extent, but only 
    to the extent, that such untrue statement or alleged untrue statement or 
    omission or alleged omission was made in the Registration Statement, the 
    Prospectus or such amendment or such supplement, in reliance upon and in 
    conformity with written information furnished to the Company by such 
    Agent specifically for use therein, (ii) in the case of the sale of Notes 
    by such Agent pursuant to a Purchase Agreement to any person, the failure 
    of such Agent to send or give to such person a copy of the Prospectus, as 
    amended or supplemented, with or prior to the written confirmation of the 
    sale involved to the extent that the Prospectus, as amended or 
    supplemented, if so sent or delivered, would have cured the defect in the 
    Prospectus giving rise to such losses, claims, damages, liabilities or 
    actions, or (iii) the failure of such Agent to send or deliver to any 
    person an Amended Prospectus or Supplement, with or prior to the written 
    confirmation of a sale pursuant to a Purchase Agreement, to which Amended 
    Prospectus or Supplement the Agent shall not have objected pursuant to 
    Section 5(a) hereof and which the Company shall have furnished to such 
    Agent, if any event shall have occurred as a result of which (x) the 
    Current Prospectus would include an untrue statement of a material fact 
    or omit to state a material fact necessary in order to make the 
    statements therein, in light of the circumstances under which they were 
    made when such Prospectus is delivered, not misleading and (y) the 
    Amended Prospectus or Supplement, as the case may be, so sent or 
    delivered, would have cured the defect in the Current Prospectus giving 
    rise to such losses, claims, damages, liabilities or actions.  This 
    indemnity agreement will be in addition to any liability which such 
    Agents may otherwise have.  

         (c)  Promptly after receipt by an indemnified party under this 
    Section 7 of notice of the commencement of any action, such indemnified 
    party will, if a claim in respect thereof is to be made against the 
    indemnifying party under this Section 7, notify the indemnifying party in 
    writing of the commencement thereof, but the omission so to notify the 
    indemnifying party will not relieve it from any liability which it may 
    have to any indemnified party otherwise than under this Section 7.  In 
    case any such action is brought against any indemnified party, and it 
    notifies the indemnifying party of the commencement thereof, the 
    indemnifying party will be entitled to participate in, and, to the extent 
    that it may wish, jointly with any other indemnifying party, similarly 
    notified, to assume the defense thereof, with counsel satisfactory to 
    such indemnified party, and 

                                   20

<PAGE>

    after notice from the indemnifying party to such indemnified party of its 
    election so to assume the defense thereof, the indemnifying party will 
    not be liable to such indemnified party under this Section 7 for any 
    legal or other expenses subsequently incurred by such indemnified party 
    in connection with the defense thereof other than reasonable costs of 
    investigation, unless, in the case of an indemnification obligation 
    arising under subparagraph (a) of this Section 7, (i) the employment of 
    additional counsel has been authorized in writing by the Company in 
    connection with defending such action, or (ii) the Company and such Agent 
    or controlling person are advised by such additional counsel that such 
    Agent or controlling person has available defenses involving a potential 
    conflict with the interests of the Company, in either of which events, 
    the fees and expenses of such additional counsel shall be borne by the 
    Company. 

         (d)  If the indemnification provided for in this Section 7 is 
    unavailable (or insufficient to hold harmless an indemnified party) under 
    subparagraph (a) or (b) above (by reason of a failure of the indemnified 
    party to give a notice required by subparagraph (c) above or for any 
    other reason whatever) to a party that would have been an indemnified 
    party under subparagraph (a) or (b) above ("indemnified party") in 
    respect of any losses, claims, damages, liabilities or actions referred 
    to therein, then each party that would have been an indemnifying party 
    thereunder ("indemnifying party") shall, in lieu of indemnifying such 
    indemnified party, contribute to the amount paid or payable by such 
    indemnified party as a result of such losses, claims, damages, 
    liabilities or actions in such proportion as is appropriate to reflect 
    the relative benefits received by the Company on the one hand and each 
    Agent on the other from the offering of the Notes to which such loss, 
    claim, damage or liability (or action in respect thereof) relates and the 
    relative fault of the Company on the one hand and each Agent on the other 
    in connection with the statements or omissions which resulted in such 
    losses, claims, damages, liabilities or actions, as well as any other 
    relevant equitable considerations.  The relative benefits received by the 
    Company on the one hand and each Agent on the other shall be deemed to be 
    in the same proportion as the total net proceeds from the offering 
    (before deducting expenses) received by the Company bear to the total 
    commissions (or discounts) received by each Agent with respect to such 
    offering.  The relative fault of the Company on the one hand and each 
    Agent on the other hand shall be determined by reference to, among other 
    things, whether the untrue or alleged untrue statement of a material fact 
    or the omission or alleged omission to state a material fact relates to 
    information supplied by the Company or by such Agent and the parties' 
    relative intent, knowledge, access to information and opportunity to 
    correct or prevent such statement or omission.  Each Agent's obligation 
    to contribute pursuant to this Section 7 shall be several in the 
    proportion that the principal amount of the Notes the sale of which by or 
    through such Agent gave rise to such losses, claims, damages or 
    liabilities bears to the aggregate principal amount of the Notes the sale 
    of which by or through any Agent gave rise to such losses, claims, 
    damages or liabilities, and not joint.  The Company and the Agents agree 
    that it would not be just and equitable if contribution pursuant to this 
    subparagraph (d) were determined by pro rata allocation (even if the 
    Agents were treated as one entity for such purpose) or by any other 
    method of allocation which does not take

                                   21

<PAGE>

    account of the equitable considerations referred to above in this 
    subparagraph (d).  The amount paid or payable by an indemnified party as 
    a result of the losses, claims, damages, liabilities or actions referred 
    to above in this subparagraph (d) shall be deemed to include any legal or 
    other expenses reasonably incurred by such indemnified party in 
    connection with investigating or defending any such action or claim 
    (which shall be limited as provided in subparagraph (c) above if the 
    indemnifying party has assumed the defense of any such action in 
    accordance with the provisions thereof).  Notwithstanding the provisions 
    of this Section 7, no Agent shall be required to contribute any amount in 
    excess of the amount by which the total price at which the Notes that 
    were offered and sold to the public through such Agent exceeds the amount 
    of any damages which such Agent has otherwise been required to pay by 
    reason of such untrue or alleged untrue statement or omission or alleged 
    omission.  No person guilty of fraudulent misrepresentation (within the 
    meaning of Section 11(f) of the Act) shall be entitled to contribution 
    from any person who was not guilty of such fraudulent misrepresentation.  
    The remedies provided for in this Section 7 are not exclusive and shall 
    not limit any rights or remedies which may otherwise be available to any 
    indemnified party at law or in equity.  

    SECTION 8.  Status of each Agent.  In soliciting offers to purchase the 
Notes from the Company pursuant to this Agreement (other than in respect of 
any Purchase Agreement), each Agent is acting individually and not jointly 
and is acting solely as agent for the Company and not as principal.  Each 
Agent will make reasonable efforts to assist the Company in obtaining 
performance by each purchaser whose offer to purchase Notes from the Company 
has been solicited by such Agent and accepted by the Company, but such Agent 
shall have no liability to the Company in the event any such purchase is not 
consummated for any reason. If the Company shall default in its obligations 
to deliver Notes to a purchaser whose offer it has accepted, the Company 
shall (a) hold the Agents harmless against any loss, claim or damage arising 
from or as a result of such default by the Company and (b), in particular, 
pay to the Agents any commission to which they would be entitled in 
connection with such sale.

    SECTION 9.  Representations and Warranties to Survive Delivery.  All 
representations and warranties of the Company contained in this Agreement, or 
contained in certificates of officers of the Company submitted pursuant 
hereto, shall remain operative and in full force and effect, regardless of 
the termination or cancellation of this Agreement or any investigation made 
by or on behalf of any Agent or any person controlling such Agent or by or on 
behalf of the Company, and shall survive each delivery of and payment for any 
of the Notes.

    SECTION 10.  Termination.  The appointment of an Agent and the 
obligations of such Agent under this Agreement may be terminated at any time 
either by the Company or by such Agent upon the giving of one day's written 
notice of such termination to such Agent or the Company, as the case may be.  
The provisions of Sections 2(c), 3(d), 3(f), 3(g), 4, 7, 8, 9, 12, 13 and 14 
hereof shall survive any such termination.

                                   22

<PAGE>


    SECTION 11.  Additional Agents.  The Company may appoint one or more 
additional agents for the purpose of soliciting or receiving offers to 
purchase the Notes from the Company by others; provided that any such 
additional agent shall become a party to this Agreement prior to soliciting 
or receiving offers to purchase the Notes.

    SECTION 12.  Notices.  Except as otherwise provided herein, all notices 
and other communications hereunder shall be in writing and shall be deemed to 
have been duly given if mailed or transmitted by any standard form of 
telecommunication.  Notices to the Agents shall be directed to them as

party may designate from time to time by notice duly given in accordance with 
the terms of this Section 12.  

    SECTION 13.  Binding Effect; Benefits.  This Agreement shall be binding 
upon each Agent, the Company, and their respective successors.  This 
Agreement and the terms and provisions hereof are for the sole benefit of 
only those persons, except that (a) the representations, warranties, 
indemnities and agreements of the Company contained in this Agreement shall 
also be deemed to be for the benefit of the person or persons, if any, who 
control any Agent within the meaning of the Act or the Exchange Act, and (b) 
the indemnity agreement of the Agents contained in Section 7 hereof shall be 
deemed to be for the benefit of directors of the Company, officers of the 
Company who have signed the Registration Statement and any person controlling 
the Company within the meaning of said Act or the Exchange Act.  Nothing in 
this Agreement is intended or shall be construed to give any person, other 
than the persons referred to in this Section, any legal or equitable right, 
remedy or claim under or in respect of this Agreement or any provision 
contained herein.  No purchaser of any of the Notes from any Agent shall be 
construed as a successor or assign merely by reason of such purchase.

    SECTION 14.  Governing Law; Counterparts.  This Agreement shall be 
governed by and construed in accordance with the laws of New York.  This 
Agreement may be executed by the parties on separate counterparts and the 
executed counterparts shall together constitute a single instrument.

                              ADMINISTRATIVE PROCEDURES


    The Collateralized Medium-Term Notes, Series D, due from nine months to 
40 years from their issue date (the "Notes"), are to be offered on a 
continuing basis by Sierra Pacific Power Company (the "Issuer").  Lehman 
Brothers, Lehman Brothers, Inc., A.G. Edwards & Sons, Inc. and UBS Securities 
LLC, as agents, have each agreed to use reasonable efforts to solicit offers 
to purchase the Notes.  No Agent will be obligated to purchase Notes for its 
own account.  The Notes are being sold pursuant to a Distribution Agreement, 
dated February 21, 1997 (the "Agency Agreement"), among the Issuer and 
Agents, and will be issued pursuant to an Indenture, dated as of June 1, 
1992, as supplemented (the "Indenture"), between the Issuer and Bankers Trust 
Company, as trustee (the "Trustee").  The Notes will be secured by one or 
more series of first mortgage bonds to be issued to and pledged by the Issuer 
with the Trustee and will have been registered under the Securities Act of 
1933, as amended (the "Act").  For a description of the terms of the Notes 
and the offering and sale thereof, see the sections entitled "Description of 
Notes," "Supplemental Plan of Distribution" and "Glossary" in the Prospectus 
Supplement relating to the Notes, dated February 28, 1997, attached hereto 
and hereinafter referred to as the "Prospectus Supplement," and the sections 
entitled "Description of Debt Securities," "United States Taxation" and "Plan 
of Distribution" in the Prospectus relating to the Notes, dated December 20, 
1996, attached hereto and hereinafter referred to as the "Prospectus."  
Defined terms used herein but not defined herein shall have the meanings 
assigned to them in the Distribution Agreement, the Prospectus or the 
Prospectus Supplement, as appropriate.

    The Notes will be represented either by Global Notes delivered to The 
Depository Trust Company ("DTC") or its nominee and recorded in the 
book-entry system maintained by DTC or such nominee ("Book-Entry Notes") or 
by certificates delivered to the Holders thereof or Persons designated by 
such Holders ("Certificated Notes").  Notes for which interest is calculated 
on the basis of a fixed interest rate are referred to herein as "Fixed Rate 
Notes."  Notes for which interest is calculated at a rate or rates determined 
by reference to an interest rate formula are referred to herein as "Floating 
Rate Notes."

    Notes which are issued at a price lower than the principal amount thereof 
and which provide that upon redemption or acceleration of the Maturity 
thereof an amount less than the principal thereof shall become due and 
payable are referred to herein as "Original Issue Discount Notes."  For 
special provisions relating to original Issue Discount Notes and other Notes 
issued at a discount for tax purposes, see the section entitled "Certain 
United States Federal Income Tax Consequences -- Original Issue Discount" in 
the Prospectus.

    The Notes will be denominated in U.S. dollars and payments of principal 
of and any premium and interest on the Notes will be made in U.S. dollars in 
the manner indicated in the Prospectus and the Prospectus Supplement.


                                      C-1


<PAGE>


    Notes which provide that amounts payable by the Issuer in respect of 
principal of or any premium or interest on the Notes shall be determined by 
reference to the value, rate or price of one or more specified indices, are 
referred to herein as "Indexed Notes."  Specific information pertaining to 
the method for determining the principal amounts payable, a historical 
comparison of the value, rate or price of the specified index, indices and 
the face amount of the Indexed Note and certain additional tax considerations 
will be described in the applicable Pricing Supplement.

    Administrative procedures and specific terms of the offering are 
explained below.  Part I indicates procedures applicable to all Notes; Part 
II indicates specific procedures for Certificated Notes; and Part III 
indicates specific procedures for Book-Entry Notes.  Administrative and 
record-keeping responsibilities will be handled for the Issuer by its Finance 
Division.  The Issuer will advise the Agents in writing of those persons 
handling administrative responsibilities with whom the Agents are to 
communicate regarding offers to purchase Notes and the details of their 
delivery.

PART I:  PROCEDURES APPLICABLE TO ALL NOTES

ISSUE DATE

    Each Note will be dated the date of its authentication.  Each Note will 
also bear an original issue date (the "Issue Date") which, with respect to 
any such Note (or portion thereof), shall mean the date of its original 
issuance and shall be specified therein.  The Issue Date will remain the same 
for all Notes subsequently issued upon transfer, exchange or substitution of 
a Note, regardless of their dates of authentication.

PRICE TO PUBLIC

    Except as otherwise specified in a Pricing Supplement, each Note will be 
issued at 100% of principal amount.

MATURITIES

    Each Note will mature on a date, selected by the purchaser and agreed to 
by the Issuer, which will be at least nine months but not more than 40 years 
after its Issue Date.

INTEREST PAYMENTS

    Interest on each interest-bearing Note will be calculated and paid in the 
manner described in such Note and in the Prospectus Supplement and the 
applicable Pricing Supplement.  Unless otherwise set forth therein, interest 
on Fixed Rate Notes (including interest for partial periods) will be 
calculated on the basis of a 360-day year of twelve 30-day months and will 
not accrue on the 31st day of any month. Interest on Floating Rate Notes, 
except as otherwise set forth therein, will be calculated on the basis of 
actual days elapsed and a year of 360 days, except that


                                       C-2


<PAGE>


in the case of a Floating Rate Note for which the Base Rate is the Treasury 
Rate, interest will be calculated on the basis of the actual number of days 
in the year.

    On the fifth Business Day immediately preceding each Interest Payment 
Date, the Trustee will furnish the Issuer with the total amount of interest 
payments to be made on such Interest Payment Date.  The Trustee will provide 
monthly, to the Issuer's Finance Division, a list of the principal and any 
premium and interest to be paid on Notes maturing in the next succeeding 
month.  The Trustee will assume responsibility for withholding taxes on 
interest paid as required by law.

REDEMPTION/REPAYMENT

    If indicated in the applicable Pricing Supplement, the Notes of a 
particular tenor will be subject to redemption in whole or in part (subject 
to applicable minimum denominations), at the option of the Issuer on and 
after an initial redemption date as set forth in the applicable Pricing 
Supplement and in the applicable Note.  The redemption price will be set 
forth in the applicable Pricing Supplement and in the applicable Note.

PROCEDURES FOR ESTABLISHING THE TERMS OF THE NOTES

    The Issuer and the Agents will discuss from time to time the rates to be 
borne by the Notes that may be sold as a result of the solicitation of offers 
by the Agents.  Once any Agent has recorded any indication of interest in 
Notes upon certain terms, and communicated with the Issuer, if the Issuer 
plans to accept an offer to purchase Notes upon such terms, it will prepare a 
Pricing Supplement to the Prospectus, as then amended or supplemented, 
reflecting the terms of such Notes and, after approval from the Agents, will 
arrange to have the Pricing Supplement filed electronically with the 
Securities and Exchange Commission (the "Commission") pursuant to Rule 424(b) 
under the Act.  The Issuer will supply at least 10 copies of the Prospectus, 
as then amended or supplemented, and bearing such Pricing Supplement, to the 
Agent who presented the offer (the "Presenting Agent") and will provide one 
copy thereof to the Trustee by facsimile transmission.  No settlements with 
respect to Notes upon such terms may occur prior to such transmitting or 
filing and the Agents will not, prior to such transmitting or filing, mail 
confirmations to customers who have offered to purchase Notes upon such 
terms.  After such transmitting or filing, sales, mailing of confirmations 
and settlements may occur with respect to Notes upon such terms, subject to 
the provisions of "Delivery of Prospectus" below.

    If the Issuer decides to post rates and a decision has been reached to 
change interest rates, the Issuer shall promptly notify each Agent.  Each 
Agent will forthwith suspend solicitation of purchases.  At that time, the 
Agents will recommend and the Issuer will establish rates to be so "posted."  
Following establishment of posted rates and prior to the transmitting or 
filing described in the preceding paragraph, the Agents may only record 
indications of interest in purchasing Notes at the posted rates.  Once any 
Agent has recorded any indication of interest in Notes at the posted rates 
and communicated with the Issuer, if the Issuer plans to accept an offer at 
the posted rates, it will prepare a Pricing Supplement reflecting such posted 
rates, and after approval from


                                       C-3


<PAGE>


the Agents, arrange to have the Pricing Supplement filed electronically with 
the Commission and will supply at least 10 copies of the Prospectus, as then 
amended or supplemented, and bearing such Pricing Supplement, to the 
Presenting Agent.  No settlements at the posted rates may occur prior to such 
transmitting or filing and the agents will not, prior to such transmitting or 
filing, mail confirmations to customers who have offered to purchase Notes at 
the posted rates.  After such transmitting or filing, sales, mailing of 
confirmations and settlements may resume, subject to the provisions of 
"Delivery of Prospectus, below.

    Outdated Pricing Supplements, and copies of the Prospectus to which they 
are attached (other than those retained for files), will be destroyed.

SUSPENSION OF SOLICITATION; AMENDMENT OR SUPPLEMENT

    As provided in the Distribution Agreement, the Issuer may instruct the 
Agents to suspend solicitation of offers to purchase at any time, and upon 
receipt of at least one Business Day's prior notice from the Issuer, the 
Agents will each forthwith suspend solicitation until such time as the Issuer 
has advised it that solicitation of offers to purchase may be resumed.

    If the Agents receive the notice from the Issuer contemplated by the 
second paragraph of Section 2(b) or by 3(c) of the Distribution Agreement, 
they will promptly suspend solicitation and will only resume solicitation as 
provided in the Distribution Agreement.  If the Issuer is required, pursuant 
to Section 3(c) of the Distribution Agreement, to prepare an amendment or 
supplement, it will promptly furnish each Agent with the proposed amendment 
or supplement; if the Issuer decides to amend or supplement the Registration 
Statement or the Prospectus relating to the Notes, it will promptly advise 
each Agent and will furnish each Agent with the proposed amendment or 
supplement in accordance with the terms of the Distribution Agreement.  The 
Issuer will file such amendment or supplement with the Commission, provide 
the Agents and the Trustee with copies of any such amendment or supplement, 
confirm to the Agents that such amendment or supplement has been filed with 
the Commission and advise the Agents that solicitation may be resumed.

    Any such suspension shall not affect the Issuer's obligations under the 
Distribution Agreement; and in the event that at the time the Issuer suspends 
solicitation of offers to purchase there shall be any offers already accepted 
by the Issuer outstanding for settlement, the Issuer will have the sole 
responsibility for fulfilling such obligations.  The Issuer will in addition 
promptly advise the Agents and the Trustee if such offers are not to be 
settled and if copies of the Prospectus as in effect at the time of the 
suspension may not be delivered in connection with the settlement of such 
offers.


                                       C-4


<PAGE>


ACCEPTANCE AND REJECTION OF OFFERS

    Each Agent will promptly advise the Issuer, at its option orally or in 
writing, of each reasonable offer to purchase Notes received by it, other 
than those rejected by such Agent.  Each Agent may, in its discretion 
reasonably exercised, without notice to the Issuer, reject any offer received 
by it, in whole or in part.  The Issuer will have the sole right to accept 
offers to purchase Notes and may reject any such offer, in whole or in part.  
If the Issuer accepts or rejects an offer, in whole or in part, the Issuer 
will promptly so notify the Presenting Agent.

CONFIRMATION

    For each accepted offer, the Presenting Agent will issue a confirmation 
to the purchaser, with a separate confirmation to the Issuer's Finance 
Division, setting forth the Purchase Information (as defined under II below 
with respect to Certificated Notes and III below with respect to Book-Entry 
Notes) and delivery and payment instructions; PROVIDED, HOWEVER, that, in the 
case of the confirmation issued to the purchaser, no confirmation shall be 
delivered to the purchaser prior to the delivery of the Prospectus referred 
to below.

DETERMINATION OF SETTLEMENT DATE

    The receipt of immediately available funds by the Issuer in payment for a 
Note and (i) in the case of Certificated Notes, the authentication and 
issuance of such Note and (ii) in the case of Book-Entry Notes, entry by the 
Presenting Agent of an SDFS (defined in III below) deliver order through 
DTC's Participant Terminal System to credit such Note to the account of a 
Participant purchasing, or acting for the purchaser of, such Note, shall, 
with respect to such Note, constitute "settlement." All offers accepted by 
the Issuer will be settled on the third Business Day next succeeding the date 
of acceptance in accordance with the "Details of Settlement" set forth below, 
unless otherwise agreed by the purchaser and the Issuer.  The settlement date 
shall be specified upon receipt of an offer to purchase.  Prior to 11:00 
a.m., New York City time, on the settlement date, the Issuer will instruct 
the Trustee to authenticate and deliver the Notes no later than 2:15 p.m., 
New York City time, on that date.

DELIVERY OF PROSPECTUS

    A copy of the Prospectus as most recently amended or supplemented on the 
date of delivery thereof (except as provided below) must be delivered to a 
purchaser prior to or together with the earlier of the delivery of (i) the 
written confirmation provided for above, and (ii) any Note purchased by such 
purchaser. (For this purpose, entry of an SDFS deliver order through DTC's 
Participant Terminal System to credit a Note to the account of a Participant 
purchasing, or acting for the purchaser of, a Note shall be deemed to 
constitute delivery of such Note.) Subject to the foregoing, it is 
anticipated that delivery of the Prospectus, confirmation and Notes to the 
purchaser will be made simultaneously at settlement.  The Issuer shall ensure 
that the Presenting Agent receives copies of the Prospectus and each 
amendment or supplement thereto (including appropriate Pricing Supplements) 
in such quantities and within such time limits as will


                                       C-5


<PAGE>


enable the Presenting Agent to deliver such confirmation or Note to a 
purchaser as contemplated by these procedures and in compliance with the 
first sentence of this paragraph.  If, since the date of acceptance of a 
purchaser's offer, the Prospectus shall have been supplemented solely to 
reflect any sale of Notes on terms different from those agreed to between the 
Issuer and such purchaser or a change in posted rates not applicable to such 
purchaser, such purchaser shall not receive the Prospectus as supplemented by 
such new supplement, but shall receive the Prospectus as supplemented to 
reflect the terms of the Notes being purchased by such purchaser and 
otherwise as most recently amended or supplemented on the date of delivery of 
the Prospectus.

AUTHENTICITY OF SIGNATURES

    The Issuer will cause the Trustee to furnish the Agents from time to time 
with the specimen signatures of each of the Trustee's officers, employees or 
agents who have been authorized by the Trustee to authenticate Notes, but no 
Agent will have any obligation or liability to the Issuer or the Trustee in 
respect of the authenticity of the signature of any officer, employee or 
agent of the Issuer or the Trustee on any Note or the Global Note (as defined 
in Part III).

ADVERTISING EXPENSES

    The Issuer will determine with the Agents the amount of advertising that 
may be appropriate in offering the Notes.  Advertising expenses will be paid 
by the Issuer.

BUSINESS DAY; LONDON MARKET DAY

    "Business Day" means any day which is not a Saturday or Sunday and is not 
a day on which banking institutions are generally authorized or obligated by 
law or executive order to close in The City of New York and, with respect to 
LIBOR notes, a London Market Day.  "London Market Day" means any day on which 
dealings in deposits in U.S. Dollars are transacted in the London interbank 
market.

TRUSTEE NOT TO RISK FUNDS

    Nothing herein shall be deemed to require the Trustee to risk or expend 
its own funds in connection with any payment made to the Issuer, the Agent, 
DTC or any Noteholder, it being understood by all parties that payments made 
by the Trustee to the Issuer, the Agent, DTC or any holder of a Note shall be 
made only to the extent that funds are provided to the Trustee for such 
purpose.

will be made in immediately available funds, PROVIDED, that the Certificated 
Note is presented in time for the Paying Agent to make payment in such funds 
in accordance with its normal procedures.  The Issuer will provide the 
Trustee (and any Paying Agent) with funds available for immediate use for 
such purpose.  Certificated Notes presented at Maturity will be canceled by 
the Trustee as provided in the Indenture.

DETAILS FOR SETTLEMENT

    For each offer for Certificated Notes accepted by the Issuer, the 
Presenting Agent shall communicate to the Issuer's Finance Division prior to

         a.   Initial Redemption Date;

         b.   Initial Redemption Price (% of par);

         c.   Amount (% of par) of decline and date;

         d.   Redemption Limitation Date.

    8.   Trade date of each Note.

    9.   Settlement date (Issue Date) of each Note.

   11.   Price.

   12.   Any additional applicable terms of each Note.

    The Issue Date of, and the settlement date for, Certificated Notes will 
be the same.  Before accepting any offer to purchase Certificated Notes to be 
settled in less than three Business Days, the Issuer shall verify that the 
Trustee will have adequate time to prepare and  authenticate the Notes.

    Immediately after receiving the details for each offer for Certificated 
Notes from the Presenting Agent, the Issuer will, after recording the details 
and any necessary calculations, communicate the Purchase Information by 
telephone, telex, facsimile transmission or other acceptable means, to the 
Trustee.  Each such instruction given by the Issuer to the Trustee shall 
constitute a continuing representation and warranty by the Issuer to the 
Trustee and the Agents that (i) the issuance and delivery of such Notes have 
been duly and validly authorized by the issuer and (ii) such Notes, when 
completed, authenticated and delivered, shall constitute the valid and 
legally binding obligation of the Issuer.  The Issuer will assign to and 
enter on each Note a transaction number.


                                       C-8

    The Issuer will deliver to the Trustee a Certificated Note.  The Trustee 
will complete such Certificated Note and will authenticate such Certificated 
Note and deliver it (with the confirmation) to such Agent, and such Agent 
will acknowledge receipt of the Note in writing delivered to the Trustee.

SETTLEMENT: NOTE DELIVERIES AND CASH PAYMENT

    The Issuer will deliver to the Trustee at the commencement of the program 
and from time to time thereafter a supply of duly executed Certificated Notes 
with preprinted control numbers adequate to implement the program.  Upon the 
receipt of appropriate documentation and instructions from the Issuer in 
accordance with the applicable Officers' Certificate and verification 
thereof, the Trustee will cause the Certificated Notes to be completed and 
authenticated and hold the Certificated Notes for delivery against payment.

    The Trustee will deliver the Certificated Notes, in accordance with 
instructions from the Issuer, to the Presenting Agent, as the Issuer's agent, 
for the benefit of the purchaser only against receipt.  The Presenting Agent 
will acknowledge receipt of the Notes through a broker's receipt.  Delivery 
of the Certificated Notes by the Trustee will be made only against such 
acknowledgment of receipt from the Presenting Agent.  Upon the Presenting 
Agent's determination that such Note has been authenticated, delivered and 
completed as aforesaid, the Presenting Agent will make, or cause to be made, 
payment to the Issuer at such account of the Issuer as it may specify in 
writing, in immediately available funds, of an amount equal to the principal 
amount of such Notes, less the applicable commission.  If the Presenting 
Agent in any instance advances its own funds, the Issuer shall not use any of 
the proceeds of such sale to acquire securities.

    The Presenting Agent, as the Issuer's agent, will deliver the Notes (with 
the written confirmation provided for above) to the purchaser thereof against 
payment therefor by such purchaser in immediately available funds.  Delivery 
of any confirmation or Note will be made in compliance with "Delivery of 
Prospectus" in Part I above.

FAILS

    In the event that a purchaser shall fail to accept delivery of and make 
payment for a Certificated Note on the settlement date, the Presenting Agent 
will notify the Trustee and the Issuer, by telephone, confirmed in writing.  
If such Certificated Note has been delivered to the Presenting Agent, as the 
Issuer's agent, the Presenting Agent stall return such Note to the Trustee.  
If funds have been advanced for the purchase of such Note, the Trustee will, 
immediately upon receipt of such Note, debit the account of the Issuer for 
the amount so advanced and the Trustee shall refund the payment previously 
made by the Presenting Agent in immediately available funds.  Such payments, 
will be made on the settlement date, if possible, and in any event not later 
than the Business Day following the settlement date.  If the fail shall have 
occurred for any reason other than the failure of the Presenting Agent to 
provide the Purchase Information to the Issuer or to provide a confirmation 
to the purchaser, the Issuer will reimburse the Presenting

<PAGE>


Agent on an equitable basis for its loss of the use of funds during the 
period when the funds were credited to the account of the Issuer.

    Immediately upon receipt of the Certificated Note in respect of which the 
fail occurred, the Trustee will make appropriate entries in its records to 
reflect the fact that the Note was never issued and the Note will be canceled 
and disposed of as provided in the Indenture.

PART III:  ADMINISTRATIVE PROCEDURES FOR BOOK-ENTRY NOTES

    In connection with the qualification of the Book-Entry Notes for 
eligibility in the book-entry system maintained by DTC, the Trustee will 
perform the custodial, document control and administrative functions 
described below, in accordance with its obligations under a Letter of 
Representations (the "Letter") from the Issuer and the Trustee to DTC dated 
as of March __, 1997 and a Medium-Term Note Certificate Agreement between 
the Trustee and DTC dated as of October 21, 1988 and its obligations as a 
participant in DTC, including DTC's Same-Day Funds Settlement System 
("SDFS"). 

FORM, DENOMINATIONS AND REGISTRATION

    All Book-Entry Notes of the same tenor and having the same Issue Date, 
will be represented initially by a single note (a "Global Note") in fully 
registered form without coupons.  Book-Entry Notes will represent Notes 
denominated in U.S. dollars. Global Notes will be issued in denominations of 
$10,000 and integral multiples of $1,000 in excess thereof.  Each Global Note 
will be registered in the name of Cede & Co., as nominee for DTC, on the 
Security Register maintained under the Indenture. The beneficial owner of a 
Book-Entry Note (or one or more indirect participants in DTC designated by 
such owner) will designate one or more participants in DTC (with respect to 
such Notes, the "Participants") to act as agent or agents for such owner in 
connection with the book-entry system maintained by DTC, and DTC will record 
in book-entry form, in accordance with instructions provided by such 
Participants, a credit balance with respect to such Note in the account of 
such Participants.  The ownership interest of such beneficial owner in such 
Note will be recorded through the records of such Participants or through the 
separate records of such Participants and one or more indirect participants 
in DTC.

CUSIP NUMBERS

    The Issuer has arranged with the CUSIP Service Bureau of Standard & 
Poor's Corporation (the "CUSIP Service Bureau") for the reservation of a 
series of CUSIP numbers (including tranche numbers), such series consisting 
of approximately 900 CUSIP numbers and relating to Global Notes representing 
Book-Entry Notes.  The Issuer has obtained from the CUSIP Service Bureau a 
written list of such reserved CUSIP numbers and has delivered it to the 
Trustee and DTC.  The Trustee will assign CUSIP numbers serially to Global 
Notes as described below under "Details for Settlement." DTC will notify the 
CUSIP Service Bureau periodically of the CUSIP numbers that the Trustee has 
assigned to Global Notes.  The Trustee will notify the Issuer at the time 
when fewer than 100 of the reserved CUSIP numbers remain unassigned to the 
Global

                                       C-10


<PAGE>


Notes; and the Issuer will reserve an additional 900 CUSIP numbers for 
assignment to Global Notes representing Book-Entry Notes.  Upon obtaining 
such additional CUSIP numbers, the Issuer shall deliver a list of such 
additional CUSIP numbers to the Trustee and DTC.   

TRANSFERS; AND EXCHANGES FOR THE PURPOSE OF CONSOLIDATION

    Transfers of a Book-Entry Note will be accomplished by book entries made 
by DTC and, in turn, by Participants (and, in certain cases, one or more 
indirect participants in DTC) acting on behalf of beneficial transferors and 
transferees of such Note.

    The Trustee may upon notice to the Issuer deliver to DTC and the CUSIP 
Service Bureau at any time a written notice (a copy of which shall be 
attached to the Global Note resulting from such exchange) specifying (i) the 
CUSIP numbers of two or more outstanding Global Notes that represent 
Book-Entry Notes of the same tenor and having the same Issue Date, and for 
which interest (if any) has been paid to the same date, (ii) a date occurring 
at least 30 days after such written notice is delivered and at least 30 days 
before the next Interest Payment Date (if any) for such Notes, on which such 
Global Notes shall be exchanged for a single replacement Global Note and 
(iii) a new CUSIP number to be assigned to such replacement Global Note.  
Upon receipt of such a notice, DTC will send to its Participants (including 
the Trustee) a written reorganization notice to the effect that such exchange 
will occur on such date. Prior to the specified exchange date, the Trustee 
will deliver to the CUSIP Service Bureau a written notice setting forth such 
exchange date and the new CUSIP number and stating that, as of such exchange 
date, the CUSIP numbers of the Global Notes to be exchanged will no longer be 
valid.  On the specified exchange date, the Trustee will exchange such Global 
Notes for a single Global Note bearing the new CUSIP number and the CUSIP 
numbers of the exchanged Global Notes will, in accordance with CUSIP Service 
Bureau procedures, be canceled and not immediately reassigned.

NOTICE OF INTEREST PAYMENT DATES AND REGULAR RECORD DATES

    To the extent then known, on the first Business Day of March, June, 
September and December of each year, the Trustee will deliver to the Issuer 
and DTC a written list of Record Dates and Interest Payment Dates that will 
occur with respect to Floating Rate Book-Entry Notes during the six-month 
period beginning on such first Business Day.


                                       C-11


<PAGE>


PAYMENTS OF PRINCIPAL AND INTEREST

    (a)  PAYMENTS OF INTEREST ONLY.  Promptly after each Regular Record Date, 
the Trustee will deliver to the Issuer and DTC a written notice specifying by 
CUSIP number the amount of interest to be paid on each Global Note on the 
following Interest Payment Date (other than an Interest Payment Date 
coinciding with Maturity) and the total of such amounts.  The Issuer will 
confirm with the Trustee the amount payable on each Global Note on such 
Interest Payment Date.  DTC will confirm the amount payable on each Global 
Note on such Interest Payment Date by reference to the daily or weekly bond 
reports published by Standard & Poor's Corporation.  The Issuer will pay to 
the Trustee the total amount of interest due on such Interest Payment Date 
(other than at Maturity), and the Trustee will pay such amount to DTC at 
times and in the manner set forth below under "Manner of Payment."

    (b)  PAYMENTS AT STATED MATURITY.  On or about the first Business Day of 
each month, the Trustee will deliver to the Issuer and DTC a written list of 
principal and interest to be paid on each Global Note maturing in the 
following month.  The Issuer, the Trustee and DTC will confirm the amounts of 
such principal and interest payments with respect to each such Global Note on 
or about the third Business Day preceding the Stated Maturity of such Global 
Note.  The Issuer will pay to the Trustee, as the paying agent, the principal 
amount of such Global Note, together with interest due at such Stated 
Maturity.  Upon surrender of a Global Note, the Trustee will pay such amounts 
to DTC at the times and in the manner set forth below under "Manner of 
Payment."  If any Stated Maturity of a Global Note representing Book-Entry 
Notes is not a Business Day, the payment due on such day shall be made on the 
next succeeding Business Day and no interest shall accrue on such payment for 
the period from and after such Stated Maturity.  Promptly after payment to 
DTC of the principal and any interest due at the Stated Maturity of such 
Global Note, the Trustee will cancel such Global Note in accordance with the 
terms of the Indenture.

    (c)  PAYMENT UPON REDEMPTION.  The Trustee will comply with the terms of 
the Letter with regard to redemptions or repayments of the Book-Entry Notes.  
In the case of Book-Entry Notes stated by their terms to be redeemable prior 
to Stated Maturity, at least 60 calendar days before the date fixed for 
redemption (the "Redemption Date"), the Issuer shall notify the Trustee of 
the Issuer's election to redeem such Book-Entry Notes in whole or in part and 
the principal amount of such Book-Entry Notes to be so redeemed.  At least 30 
calendar days but not more than 60 calendar days prior to the Redemption 
Date, the Trustee shall notify DTC of the Issuer's election to redeem such 
Book-Entry Notes.  The Trustee shall notify the Issuer and DTC of the CUSIP 
numbers of the particular Book-Entry Notes to be redeemed either in whole or 
in part.  The Issuer, the Trustee and DTC will confirm the amounts of such 
principal and any premium and interest payable with respect to each such 
Book-Entry Note on or about the third Business Day preceding the Redemption 
Date of such Book-Entry Note.  The Issuer will pay the Trustee, in accordance 
with the terms of the Indenture, the amount necessary to redeem each such 
Book-Entry Note or the applicable portion of each such Book-Entry Note.  The 
Trustee will pay such amount to DTC at the times and in the manner set forth 
herein.  Promptly after payment to DTC of the amount due on the Redemption 
Date for such Book-Entry Note, the Trustee shall cancel


                                       C-12


<PAGE>


any such Book-Entry Note redeemed in whole in accordance with the Indenture. 
If a Global Note is to be redeemed in part, the Trustee will cancel such 
Global Note and issue a Global Note which shall represent the remaining 
portion of such Global Note and shall bear the CUSIP number of the canceled 
Global Note.

    (d)  MANNER OF PAYMENT.  The total amount of any principal and interest 
due on Global Notes on any Interest Payment Date or at Maturity shall be paid 
by the Issuer to the Trustee in immediately available funds on such date.  
The Issuer will make such payment on such Global Notes by wire transfer to 
the Trustee.  The Issuer will confirm instructions regarding payment in 
writing to the Trustee.  Upon receipt of funds from the Issuer, on each date 
of Maturity of a Book-Entry Note or as soon as possible thereafter, the 
Trustee will pay by separate wire transfer (using Fedwire message entry 
instructions in a form previously specified by DTC) to an account at the 
Federal Reserve Bank of New York previously specified by DTC in funds 
available for immediate use by DTC, each payment of principal (together with 
interest thereon) due at Maturity on Book-Entry Notes.  On each interest 
Payment Date, the interest payment shall be made to DTC in same day funds in 
accordance with existing arrangements between the Trustee and DTC.  
Thereafter, on each such date, DTC will pay, in accordance with its SDFS 
operating procedures then in effect, such amounts in funds available for 
immediate use to the respective Participants in whose names the Book-Entry 
Notes represented by such Global Notes are recorded in the book-entry system 
maintained by DTC.  NEITHER THE ISSUER NOR THE TRUSTEE SHALL HAVE ANY DIRECT 
RESPONSIBILITY OR LIABILITY FOR THE PAYMENT BY DTC TO SUCH PARTICIPANTS OF 
THE PRINCIPAL OF AND ANY PREMIUM AND INTEREST ON THE BOOK-ENTRY NOTES.

    (e)  WITHHOLDING TAXES.  The amount of any taxes required under 
applicable law to be withheld from any interest payment on a Book-Entry Note 
will be determined and withheld by the Participant, indirect participant in 
DTC or other person responsible for forwarding payments and material directly 
to the beneficial owner of such Note.

<PAGE>


    Immediately after receiving the details for each offer for Book-Entry 
Notes from the Presenting Agent and in any event no later than 12:00 Noon on 
the first Business Day after the sale date (or on the sale date if such sale 
is to be settled within one Business Day), the Issuer will, after recording 
the details and any necessary calculations, communicate the Purchase 
Information by telephone, telex, facsimile transmission or other acceptable 
means, to the Trustee.  Each such instruction given by the Issuer to the 
Trustee shall constitute a continuing representation and warranty by the 
Issuer to the Trustee and the Agents that (i) the issuance and delivery of 
such Notes have been duly and validly authorized by the Issuer and (ii) such 
Notes, when completed, authenticated and delivered, shall constitute the 
valid and legally binding obligations of the Issuer.

    Immediately after receiving the Purchase Information from the Issuer and

SETTLEMENT; GLOBAL NOTE DELIVERY AND CASH PAYMENT

    The Issuer will deliver to the Trustee at the commencement of the program 
and from time to time thereafter a supply of duly executed Global Notes with 
preprinted control numbers adequate to implement the program.  Upon the 
receipt of appropriate documentation and instructions from the Issuer in 
accordance with the applicable Officers' Certificate and verification 
thereof, the Trustee will cause the Global Note to be completed and 
authenticated and hold the Global Note for delivery against payment.

    Prior to 10:00 a.m. on the Settlement Date, DTC will credit such Note to 
the Trustee's participant account at DTC.  At or prior to 2:00 p.m. on the 
Settlement Date, the Trustee will enter an SDFS deliver order through DTC's 
Participant Terminal System instructing DTC to (i) debit such Note to the 
Trustee's participant account and credit such Note to the Presenting Agent's 
participant account and (ii) debit the Presenting Agent's settlement account 
and credit the Trustee's settlement account for an amount equal to the price 
of such Note less such Agent's commission (in accordance with SDFS operating 
procedures in effect on the Settlement Date).  The entry of such a deliver 
order shall constitute a representation and warranty by the Trustee to DTC 
that (i) the Global Note representing such Note has been executed, delivered 
and authenticated and (ii) the Trustee is holding such Global Note pursuant 
to the Medium Term Note Certificate Agreement between the Trustee and DTC.

    Simultaneously with the giving of such instructions by the Trustee, the 
Presenting Agent will enter an SDFS deliver order through DTC's Participant 
Terminal System instructing DTC (i) to debit such Note to such Agent's 
participant account and credit such Note to the Participant accounts of the 
Participants with respect to such Note and (ii) to debit the settlement 
accounts of such Participants and credit the settlement account of such Agent 
for an amount equal to the price of such Note (in accordance with SDFS 
operating procedures in effect on the settlement date).

    Transfers of funds are subject to extension in accordance with any 
extension of Fedwire closing deadlines and in the other events specified in 
the SDFS operating procedures in effect on the settlement date.

    The Trustee, upon confirming receipt of such funds, will wire transfer 
the amount transferred to the Trustee, in funds available for immediate use, 
for the account of Sierra Pacific Power Company, to account no. 470017880 at 
Bank of America, Reno, Nevada (ABA No. 122400724).

FAILS

    If settlement of a Book-Entry Note is rescheduled or canceled, the Issuer 
shall notify the Trustee, and upon receipt of such notice, the Trustee will 
deliver to DTC, through DTC's Participant Terminal System, a cancellation 
message to such effect by no later than 2:00 p.m., New York City time, on the 
Business Day immediately preceding the scheduled settlement date.


                                       C-16


<PAGE>


    If the Trustee has not entered an SDFS deliver order with respect to a 
Book-Entry Note, then upon written request (which may be evidenced by 
telecopy transmission) of the Issuer, the Trustee shall deliver to DTC, 
through DTC's Participant Terminal System, as soon as practicable, but no 
later than 2:00 p.m. on any Business Day, a withdrawal message instructing 
DTC to debit such Note to the Trustee's participant account.  DTC will 
process the withdrawal message, provided that the Trustee's participant 
account contains a principal amount of the Global Note representing such Note 
that is at least equal to the principal amount to be debited. If withdrawal 
messages are processed with respect to all the Book-Entry Notes represented 
by a Global Note, the Trustee will mark such Global Note "canceled" in 
accordance with the Indenture, and make appropriate entries in the Trustee's 
records. The CUSIP number assigned to such Global Note shall, in accordance 
with CUSIP Service Bureau procedures, be canceled and not immediately 
reassigned.  If withdrawal messages are processed with respect to one or 
more, but not all, of the Book-Entry Notes represented by a Global Note, the 
Trustee will exchange such Global Note for two Global Notes, one of which 
shall represent such Book-Entry Note or Notes and shall be canceled 
immediately after issuance and the other of which shall represent the 
remaining Book-Entry Notes previously represented by the surrendered Global 
Note and shall bear the CUSIP number of the surrendered Global Note.

    If the purchase price for any Book-Entry Note is not timely paid to the 
Participants with respect to such Note by the beneficial purchaser thereof 
(or a person, including an indirect participant in DTC, acting on behalf of 
such purchaser), such participants and, in turn, the Presenting Agent may 
enter an SDFS deliver order through DTC's Participant Terminal System 
debiting such Note to such Agent's participant account and crediting such 
Note free to the participant account of the Trustee and shall notify the 
Trustee and the issuer thereof.  Thereafter, the Trustee (i) will immediately 
notify the Issuer, once the Trustee has confirmed that such Note has been 
credited to its participant account, and the Issuer shall immediately 
transfer by Fedwire (in immediately available funds) to the Presenting Agent 
an amount equal to the price of such Note which was previously sent by wire 
transfer to the account of the Issuer and (ii) the Trustee will deliver the 
withdrawal message and take the related actions described in the preceding 
paragraph. Such debits and credits will be made on the Settlement Date, if 
possible, and in any event no later than 5:00 p.m. on the following Business 
Day.  If the fail shall have occurred for any reason other than failure of 
the Presenting Agent to provide the Purchase Information to the Issuer or to 
provide a confirmation to the purchaser, the Issuer will reimburse the 
Presenting Agent on an equitable basis for its loss of the use of funds 
during the period when the funds were credited to the account of the Issuer.

    Notwithstanding the foregoing, upon any failure to settle with respect to 
a Book-Entry Note, DTC may take any actions in accordance with its SDFS 
operating procedures then in effect.  In the event of a failure to settle 
with respect to one or more, but not all, of the Book-Entry Notes to have 
been represented by a Global Note, the Trustee will provide for the 
authentication and issuance of a Global Note representing the other 
Book-Entry Notes to have been represented by such Global Note and will make 
appropriate entries in its records.

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

Gentlemen:

    This opinion is delivered to you pursuant to Section 5(e) of the 
Distribution Agreement dated as of February 21, 1997 (the "Distribution 
Agreement") between each of you and the Company relating to the issuance and 
sale from time to time of Collateralized Medium-Term Notes, Series D, in an 
initial aggregate principal amount of $35,000,000 (the "Notes").  The Notes 
are to be issued pursuant to a Collateral Trust Indenture dated as of June 1, 
1992 (the "Indenture") between the Company and Bankers Trust Company, as 
Trustee (the "Indenture Trustee"), as supplemented by a Fourth Supplemental 
Indenture dated as of February 1, 1997 between the Company and the Indenture 
Trustee (the "Fourth Supplemental Indenture") and to be secured by the 
Company's first mortgage bonds to be issued pursuant to an Indenture of 
Mortgage dated as of December 1, 1940, from the Company's predecessor to The 
New England Trust Company and Leo W. Huegle (State

Street Bank and Trust Company and Gerald R. Wheeler, respectively, by 
succession), as Trustees, as heretofore supplemented and modified and assumed 
by the Company (collectively, the "Mortgage Indenture").  This opinion is 
being delivered on the Commencement Date referred to in the Distribution 
Agreement (the "Commencement Date").

    Capitalized terms not otherwise defined herein shall have the meanings 
ascribed to them in the Distribution Agreement.

    In connection with rendering this opinion, we have examined such 
corporate records, certificates and other documents as we have considered 
necessary for the purposes of this opinion, including:

    (a)  A certificate of recent date of the Secretary of State of Nevada 
    as to the corporate existence and good standing of the Company as a 
    Nevada corporation; and a certificate of recent date of the Secretary of 
    State of California as to the qualification and good standing of the 
    Company as a foreign corporation in that State;

    (b)  The Restated Articles of Incorporation of the Company, and all 
    amendments thereto;

    (c)  The By-Laws of the Company as now in effect;

    (d)  Resolutions adopted by the Board of Directors of the Company on 
    November 13, 1996, relating to the issuance and sale of the Notes and 
    matters related thereto;

    (e)  The Indenture, the Fourth Supplemental Indenture and the proposed 
    form of fixed-rate note to be issued under the Fourth Supplemental 
    Indenture;

    (f)  The Mortgage Indenture, including the Thirty-fifth Supplemental 
    Indenture thereto dated as of February 1, 1997 (the "Thirty-fifth 
    Supplemental Indenture");

    (g)  The applications of the Company to the PSCN and the CPUC with 
    respect to the issuance and sale of the Notes and related matters, and 
    the order of the PSCN thereon dated October 19, 1995 and the opinion of 
    the CPUC thereon dated August 11, 1995;

    (h)  The Registration Statement and all exhibits thereto, as filed with 
    the Commission on November 27, 1996, and as amended by a Pre-Effective 
    Amendment No. 1 filed with the Commission on December 18, 1996, and 
    declared effective by the Commission on December 20, 1996;

    (i)  The documents incorporated by reference in the Prospectus (the 
    "Incorporated Documents");

    (j)  The First Mortgage Bond of the NN Series issued under the Mortgage 
    Indenture in connection with the Notes (the "Bond");

    (k)  Such other documents as are to be delivered on the Commencement 
    Date, including certificates of officers of the Company.

     In such examination, we have assumed the genuineness of all signatures 
other than the signatures of the Company, the authenticity of all documents 
submitted to us as originals, the conformity to the original documents of all 
documents submitted to us as copies and the authenticity of the originals of 
such latter documents.  As to any facts material to our opinion, we have, 
when relevant facts were not independently established, relied upon the 
aforesaid records, certificates and documents.

    Although we have examined the Restated Articles of Incorporation, as 
amended, of the Company, we have ourselves made no independent examination as 
to the organization, existence or standing of the Company, its authority to 
do business in California, its titles to properties, the lien of the Mortgage 
Indenture, the recording of the Mortgage Indenture and the Thirty-fifth 
Supplemental Indenture and matters of Nevada and California law affecting the 
enforceability of the obligations of the Company in respect of the Notes, the 
Indenture, the Fourth Supplemental Indenture, the Mortgage Indenture, the 
Thirty-fifth Supplemental Indenture and the Mortgage Bonds, or the 
jurisdiction and approvals of State regulatory commissions or requirements of 
the laws of Nevada or California with respect to action by or documents 
required to be filed with State officials.  We have, therefore, in connection 
with the opinions set forth below, relied with your consent as to all matters 
governed by the laws of the State of Nevada, upon a letter of even date 
herewith addressed to you by Woodburn and Wedge, and as to all matters 
governed by the laws of the State of California, upon a letter of even date 
herewith addressed to you by Graham & James LLP, and, as to such matters, our 
opinions are subject to all of the qualifications and assumptions set forth 
in such letters.  We refer you to said letters for the matters covered 
thereby and believe that you and we are entitled to rely thereon.

    We are not passing in any way upon any computations or financial 
statements, including the notes or schedules thereto, or upon any other 
financial or accounting information set forth or referred to in the 
Registration Statement or the Incorporated Documents, and have not reviewed 
the financial records or books of account of the Company.

    Prior to November 27, 1996, we participated in conferences with officers 
and other representatives of the Company and its accountants in which the 
affairs of the Company and the contents of the Registration Statement and 
Incorporated Documents were discussed at length.  Subsequent to November 27, 
1996, we made inquiries of certain officers of the Company and 
representatives of its auditors as to whether there had been any material 
change in the affairs of the Company since that date and we examined, among 
other documents, those to be delivered on the Commencement Date.  However, 
there is no assurance that all possible material facts as to the Company were 
disclosed at such conferences, in response to our inquiries, or in such 
documents, and we have to a large extent relied upon the statements of 
officers and other representatives of the Company as to the materiality of 
those facts disclosed to us.  Except with respect to the descriptions 
specifically referred to in paragraphs (d) and (j), we are not passing upon 
and do not assume any responsibility for the accuracy or completeness of the 
statements contained in the Registration Statement or the Incorporated 
Documents. 

    Based on the foregoing and, to the extent indicated above on said 
opinions of other counsel for the Company, we are of the opinion that:

    (a)  The Company is a corporation duly organized and existing in good 
    standing under the laws of the State of Nevada, with corporate power and 
    authority to own its properties and conduct its business as described in 
    the Registration Statement; and the Company is duly qualified to do 
    business as a foreign corporation in good standing in all other 
    jurisdictions in which it owns or leases substantial properties;

    (b)  The Indenture and the Fourth Supplemental Indenture have been duly 
    authorized, executed and delivered by the Company and are duly qualified 
    under the Trust Indenture Act and constitute the legal, valid and 
    binding obligations of the Company enforceable in accordance with their 
    respective terms, subject to bankruptcy, insolvency, reorganization, 
    moratorium, fraudulent transfer and similar laws of general 
    applicability relating to or affecting creditors' rights and to general 
    equity principles;

    (c)  The creation, issuance and sale of the Notes have been duly 
    authorized by the Company in conformity with the Indenture, and, when 
    the terms of a particular Debt Security and of its issuance and sale 
    have been duly authorized and established by all necessary corporate 
    action in conformity with the Indenture, and such Debt Security has been 
    duly completed, executed, authenticated and issued in accordance with 
    the Indenture and delivered against payment as contemplated by the 
    Distribution Agreement, such Debt Security will be entitled to the 
    benefits of the Indenture and will constitute a valid and legally 
    binding obligation of the Company enforceable in accordance with its 
    terms, subject to bankruptcy, insolvency, reorganization, moratorium, 
    fraudulent transfer,

    and similar laws of general applicability relating to or affecting 
    creditors' rights and to general equity principles, it being assumed 
    that (i) at the time of the issuance, sale and delivery of each Debt 
    Security the authorization of such series will not have been modified or 
    rescinded and there will not have occurred any change in law affecting 
    the validity, legally binding character or enforceability of such Debt 
    Security, and (ii) for purposes of this subparagraph (c), neither the 
    issuance, sale and delivery of any Debt Security, nor any of the terms 
    of such Debt Security, nor compliance by the Company with such terms, 
    will violate any applicable law, any agreement or instrument then 
    binding upon the Company or any restriction imposed by any court or 
    governmental body having jurisdiction over the Company, in each case 
    effected after the date hereof;

    (d)  The Registration Statement has become effective under the Act, the 
    Prospectus has been or will be transmitted by a means reasonably 
    calculated to result in filing with the Commission in conformity with 
    the provisions of Rule 424(b)(5) under the Act and no stop order 
    suspending the effectiveness of the registration statement or of any 
    part thereof has been issued and no proceedings for that purpose have 
    been instituted or, to the best of our knowledge are pending or 
    contemplated under the Act; and the registration statement relating to 
    the Registered Securities, as of its effective date, and the 
    Registration Statement and the Prospectus, as of the Commencement Date, 
    complied and complies as to form in all material respects with the 
    requirements of the Act, the Exchange Act, the Trust Indenture Act and 
    the rules and regulations under such Acts; we have no reason to believe 
    that such Registration Statement, as of its effective date, or the 
    Registration Statement, as of the Commencement Date, contained or 
    contains any untrue statement of a material fact or omitted or omits to 
    state any material fact required to be stated therein or necessary to 
    make the statements therein not misleading or that the Prospectus, as of 
    the Commencement Date, contains or contained any untrue statement of a 
    material fact or omits or omitted to state any material fact necessary 
    in order to make the statements therein, in the light of the 
    circumstances under which they were made, not misleading; the 
    descriptions and statements in the Prospectus and reviewed by us and 
    made on our authority as stated under the caption "Experts" are accurate 
    and fairly present the information required to be shown; and we do not 
    know of any legal or governmental proceedings required to be described 
    in the Registration Statement which are not described as required or of 
    any contracts or documents of a character required to be described in 
    the Registration Statement or the Prospectus or to be filed as exhibits 
    to the Registration Statement which are not described and filed as 
    required; provided, however, that we do not express any belief as to any 
    information contained in the Registration Statement, the Prospectus or 
    the Incorporated Documents which is specified therein to have been 
    obtained from The Depository Trust Company, or as to any

    statements contained in the Statements of Eligibility (Form T-l) under 
    the Trust Indenture Act of the Trustee filed as an exhibit to the 
    Registration Statement;

    (e)  The Mortgage Indenture has been duly authorized, executed and 
    delivered by the Company and has been qualified under the Trust 
    Indenture Act.  The Thirty-fifth Supplemental Indenture has been duly 
    authorized, executed and delivered by the Company.  Each of the Mortgage 
    Indenture and the Thirty-fifth Supplemental Indenture is a legal, valid 
    and binding obligation of the Company enforceable against the Company in 
    accordance with its terms, subject to bankruptcy, insolvency, 
    reorganization, moratorium, fraudulent transfer and similar laws of 
    general applicability relating to or affecting creditors' rights and 
    general equity principles;

    (f)  Upon the deposit of the Mortgage Bonds with the Trustee as the 
    basis for the issuance of the Notes, to the extent that such Mortgage 
    Bonds shall have been designated as Designated Mortgage Bonds, the 
    Mortgage Bonds shall be duly pledged to the Trustee, and the Indenture 
    will, upon payment for the Notes issued upon the basis of the Designated 
    Mortgage Bonds so deposited, constitute a valid first lien thereupon; no 
    registration, recording or filing of the Indenture (or notices or 
    financing statements in respect thereof) is required by law to make 
    effective and to maintain the lien on the Designated Mortgage Bonds so 
    deposited intended to be created by the Indenture;

    (g)  The Mortgage Bonds to be deposited with the Trustee and the 
    Designated Mortgage Bonds to be pledged with the Trustee as the basis 
    for the issuance of the Notes, have been duly authorized and, upon the 
    deposit and pledge thereof in the manner contemplated by the Indenture, 
    will be validly issued in conformity with the Mortgage Indenture, and 
    constitute legal, valid and binding obligations of the Company, subject 
    to bankruptcy, insolvency, reorganization, moratorium, fraudulent 
    transfer and similar laws of general applicability relating to or 
    affecting creditors' rights and general equity principles and will be 
    entitled to the security afforded by the Mortgage Indenture equally and 
    ratably with the securities outstanding thereunder;

    (h)  No consent, approval, authorization or order of, or filing with, 
    any governmental agency or body or any court is required for the 
    consummation of the transactions contemplated by the Distribution 
    Agreement in connection with the issuance and sale of the Notes by the 
    Company, except with the Commission and except such as may be required 
    under state securities laws (we assume, with your permission, that with 
    respect to each particular Debt Security, inclusion of any alternative 
    or additional terms in such Debt Security that are not currently 
    specified in the forms of Notes examined by us would not require the 
    Company to obtain any regulatory consent, authorization or

    issue, sell and deliver such Security), and except for filings with and 
    the orders from the PSCN and the CPUC authorizing the issuance and sale 
    by the Company of the Notes, subject to certain conditions set forth 
    therein, which orders have been obtained and are in full effect;

    (i)  The execution, delivery and performance of the Indenture, the 
    Fourth Supplemental Indenture, the Thirty-fifth Supplemental Indenture 
    and the Distribution Agreement, the issuance of the Mortgage Bonds, the 
    pledge of the Designated Mortgage Bonds and the issuance and sale of the 
    Notes, and compliance with the terms, conditions and provisions thereof, 
    will not result in a breach or violation of any of the terms, conditions 
    and provisions of, or constitute a default under, any statute, any rule, 
    regulation or order of any governmental agency or body or any court 
    having jurisdiction over the Company or any subsidiary of the Company or 
    any of their properties or any agreement or instrument known to us to 
    which the Company or any such subsidiary is a party or by which the 
    Company or any such subsidiary is bound or to which any of the 
    properties of the Company or any such subsidiary is subject, or the 
    charter or by-laws of the Company or any such subsidiary.  The Company 
    has full power and authority to authorize, issue and sell the Notes as 
    contemplated by the Distribution Agreement (it being understood that we 
    have assumed with respect to each particular Debt Security that the 
    inclusion of any alternative or additional terms in such Debt Security 
    that are not currently specified in the form of Notes examined by us 
    will not cause the issuance, sale or delivery of such Debt Security, the 
    terms of such Debt Security, or the compliance by the Company with such 
    terms, to violate any of the orders or laws specified in this paragraph 
    or to result in a default under or breach of any of the agreements 
    specified in this paragraph);

    (j)  The forms of the Notes and the Mortgage Bonds conform as to legal 
    matters in all material respects with the statements concerning them in 
    the Registration Statement and Prospectus;

    (k)  The Distribution Agreement has been duly authorized, executed and 
    delivered by the Company; and

    (l)  The Company is not a holding company or a subsidiary of a 
    registered holding company within the meaning of the Public Utility 
    Holding Company Act of 1935.

     This opinion is rendered to you solely in connection with the 
consummation of the transactions contemplated by the Distribution Agreement

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

Ladies and Gentlemen:

    As special Nevada counsel for Sierra Pacific Power Company (the 
"Company"), we are furnishing this opinion to you pursuant to Section 5(f) of 
the Distribution Agreement dated February 21, 1997 (the "Distribution 
Agreement") between the Company and each of Lehman Brothers, Inc., A.G. 
Edwards & Sons, Inc. and UBS Securities LLC as Agents in connection with the 
issuance of Collateralized Medium Term Notes, Series D, in an initial 
aggregate principal amount of $35,000,000 (the "Notes"), to be issued from 
time to time by the Company and secured by $35,000,000 of First Mortgage 
Bonds, 9%, Series NN due 2037 to be issued by the Company.  All capitalized 
terms used herein without definition and defined in the Distribution 
Agreement are used herein as therein defined.

    In connection with rendering this opinion, we have examined the following 
documents:
    
    (a)  A Certificate of Corporate Existence issued by the Secretary of 
State of Nevada;

    (b)  The Restated Articles of Incorporation of the Company and all 
amendments thereto (the "Charter");

    (c)  The By-laws of the Company as now in effect;

    (d)  Resolutions adopted by the Board of Directors of the Company on 
November 13, 1996, relating to the issuance and sale of the notes and matters 
related thereto;

    (e)  The Indenture, including the Fourth Supplemental Indenture and the 
proposed form of fixed-rate note to be issued under the Fourth Supplemental 
Indenture;

    (f)  The Mortgage Indenture, including the Thirty-fifth Supplemental 
Indenture thereto dated as of February 1, 1997 (the "Thirty-fifth 
Supplemental Indenture");

    (g)  Fully executed counterparts or copies of the order of the Public 
Service Commission of Nevada issued on October 19, 1995, Docket No. 95-6034 
(the "Order");

    (h)  The Mortgage Bonds;

    (i)  The Distribution Agreement;

    (j)  The Registration Statement of the Company on Form S-3 as filed with
the Securities and Exchange Commission (File No. 333-17041) under the Securities
Act of 1933, as amended, including the Prospectus relating to the Notes dated
December 20, 1996 (the "Prospectus"); and 

    (k)  Such other records, instruments and agreements as we have deemed
appropriate for the purposes of this opinion.

     We have also examined evidence satisfactory to us relating to the 
recordation and filing of the Indenture of Mortgage dated as of December 1, 
1940, between the Company and The New England Trust Company (State Street 
Bank and Trust Company, as successor trustee) and Leo W. Huegle (Gerald R. 
Wheeler, as successor trustee), as trustees (the "1940 Indenture of 
Mortgage") and the First through the Thirty-fourth supplements thereto.

     In our examination, we have assumed the genuineness and authenticity of 
all signatures other than the signatures of the Company; the accuracy and 
authenticity of all records, instruments and agreements submitted to us as 
originals; the conformity to the original documents of all documents 
submitted to us as copies; the authenticity of the originals of such copies; 
the accuracy, completeness and authenticity of all certificates of public 
officials and others as of the date hereof; and the due execution and 
delivery pursuant to due authorization thereof by, and the validity and 
binding effect thereof on, each party thereto other than the Company.  As to 
any facts material to our opinion, we have, when relevant facts were not 
independently established, relied upon certificates of the Company or its 
officers or of public officials.

     We have not examined the Notes or the Mortgage Bonds, except specimens 
thereof, and we have assumed with respect to each particular Note and 
Mortgage Bond that the inclusion of any alternative or additional terms in 
such Note or Mortgage Bond that are not currently specified in the form of 
Note or Mortgage Bond examined by us will not cause the issuance or sale of 
such Note, the issuance and delivery of such Mortgage Bond, the terms of such 
Note or Mortgage Bond, or the compliance by the Company with such terms, to 
breach or violate any of the terms of the Order.

     As used in this opinion, the expression "to the best of our knowledge" 
with reference to matters of fact means that, after an examination of the 
documents made available to us by the Company and after inquiries of 
officers, managers or employees of the Company, we find no reason to believe 
that the opinions expressed herein are factually inaccurate; but beyond that, 
we have not made an independent factual investigation for the purpose of 
rendering this opinion. 

     We have made such examination of law as in our judgment is necessary or 
appropriate for purposes of this opinion.  We do not, however, purport to be 
qualified to pass upon, and express no opinion as to, federal law or the laws 
of any jurisdiction other than the laws of the

State of Nevada (excluding therefrom principles of conflicts of laws, 
securities or blue sky laws, and laws of political subdivisions of such 
State).

    Based upon and subject to the foregoing, we are of the opinion that:

          (A)  The Company is a corporation duly organized and existing and   
   in good standing under the laws of the State of Nevada, duly qualified to 
   hold property and to transact an electric, gas and water public utility 
   business in the State of Nevada, and with powers adequate for the 
   execution and delivery of Distribution Agreement, the Indenture, the 
   Notes, the Fourth Supplemental Indenture, the Mortgage Bonds and the 
   Thirty-fifth Supplemental Indenture;

          (B)  The Mortgage Indenture, and all supplements thereto (including 
    the Thirty-fifth Supplemental Indenture), has been duly authorized, 
    executed and delivered on behalf of the Company and (assuming the due 
    authorization, execution and delivery on behalf of the other parties 
    thereto) is enforceable in accordance with its terms under the laws of 
    Nevada except that the enforcement of the rights and remedies created 
    thereby is subject to bankruptcy, insolvency, reorganization, moratorium 
    and similar laws of general application affecting the rights and remedies 
    of creditors and that the availability of the remedy of specific 
    performance or of injunctive relief is subject to the discretion of the 
    court before which any proceedings therefor may be brought and except that 
    the provisions of the Mortgage Indenture subjecting to the lien thereof 
    after-acquired property of the Company may not be effective in some cases 
    prior to the execution, delivery and recording of a supplemental indenture 
    specifically subjecting such after-acquired property to the lien of the 
    Mortgage Indenture.

          Without limiting the generality of the foregoing qualifications, we 
    call your attention to certain laws of the State of Nevada of general 
    application affecting the rights and remedies of creditors, including 
    without limitation the prohibition against unilateral right of entry in 
    the event of default of the debtor, limitations on the form of action 
    necessary to enforce a debt secured by real property, anti-deficiency 
    judgment laws, the rights of debtors and junior lien holders to 
    redemption following judicial foreclosure, and the effect of court cases 
    that have held that certain provisions of agreements are unenforceable 
    where enforcement would violate the creditor's implied covenant of good 
    faith and fair dealing or where it cannot be demonstrated that

    necessary for the protection of the security. In addition, we call your 
    attention to the fact that any purchaser at foreclosure sale or any other 
    party other than the Company would probably have to qualify as a public 
    utility under the laws of the State of Nevada and/or qualify as an 
    assignee of the Company under its governmental franchises, permits and 
    licenses in order to own or operate the properties of the Company as a 
    public utility. 

          (C)  The Mortgage Bonds to be deposited with the Trustee and the    
    Designated Mortgage Bonds pledged with the Trustee as the basis for the 
    issuance of the Notes, have been duly authorized and executed by the 
    Company and, upon the deposit and pledge thereof in the manner 
    contemplated by the Indenture, will constitute legal, valid and binding 
    obligations of the Company, subject, as to enforcement, to laws relating 
    to or affecting generally the enforcement of creditors' rights, 
    including, without limitation, bankruptcy, insolvency, reorganization, 
    moratorium and similar laws of general application affecting the rights 
    and remedies of creditors and to general principles of equity including 
    the availability of the remedy of specific performance or of injunctive 
    relief and will be entitled  to the security afforded by the Mortgage 
    Indenture equally and ratably with the securities outstanding thereunder.

          (D)  The creation, issuance and sale of the Notes have been duly
     authorized by the Company; and the Indenture and Fourth Supplemental
     Indenture have been duly authorized, executed and delivered on behalf of
     the Company.

          (E)  The Indenture, the Notes, the Fourth Supplemental Indenture, the
     Mortgage Bonds and the Thirty-fifth Supplemental Indenture will not result
     in a breach or violation of any of the terms, conditions and provisions 
     of, or constitute a default under, (i) the Charter or the By-laws of the
     Company; (ii) any statute, rule or regulation of the State of Nevada; or
     (iii) any order of any court or governmental agency of the State of 
     Nevada having jurisdiction over the Company or any of its properties, 
     which order is material to the Company taken as a whole.

          (F)  The Order remains in full force and effect in the form issued 
     and no other authorization, approval or other action by, and no notice to 
     or filing or registration with, any governmental authority or regulatory 
     body of the State of Nevada is required for the due execution, delivery 
     and performance by the Company of the Indenture, the Notes,

    the Fourth Supplemental Indenture, the Mortgage Bonds or the Thirty-fifth 
    Supplemental Indenture, except in accordance with the terms of its 
    authorizing orders.

          (G)  To the best of our knowledge and except as set forth in the
     Prospectus, there is no pending or threatened action or proceeding before
     any court, governmental agency or arbitrator against, directly involving 
     or affecting the Company or any of its subsidiaries which, in any case, 
     may materially and adversely affect the ability of the Company to perform 
     its obligations under the Indenture, the Notes, the Fourth Supplemental
     Indenture, the Mortgage Bonds or the Thirty-fifth Supplemental Indenture.

          (H)  The Mortgage Indenture and all supplements thereto (including 
     the Thirty-fifth Supplemental Indenture) (or appropriate financing 
     statements) have been duly recorded or filed in all places in the State 
     of Nevada where such recording or filing is necessary to perfect the 
     lien of the Mortgage Indenture as a lien on and security interest in 
     both real and personal property of the Company subjected thereto. 
     Notwithstanding the foregoing, (i) we express no opinion regarding the 
     lien of the Mortgage Indenture as against franchises, permits and other 
     personal property, which, under Nevada law, may not be made subject to a 
     personal property lien, and (ii) we express no opinion as to the 
     perfection of the security interest in any Personal Property in which, 
     under the provisions of the Nevada Uniform Commercial Code, a security 
     interest cannot be perfected by filing a financing statement.

          (I)  No taxes (as distinguished from filing and recordation fees) 
     are payable to the State of Nevada or any subdivision or agency thereof 
     in connection with the execution and delivery of the Notes, the Mortgage 
     Bonds or the Thirty-fifth Supplemental Indenture.

whom it is addressed in connection with the transactions described herein and

Ladies and Gentlemen:

    As special California counsel for Sierra Pacific Power Company (the 
"Company"), we are furnishing this opinion to you pursuant to Section 5(g) of 
the Distribution Agreement dated February 21, 1997 (the "Distribution 
Agreement") between the Company and each of Lehman Brothers, Inc., A.G. 
Edwards & Sons, Inc., and UBS Securities LLC as agents (each, an "Agent" and, 
collectively, the "Agents") in connection with the proposed issuance and sale 
from time to time of Collateralized Medium-Term Notes, Series D (the "Notes").
The Notes are to be issued pursuant to a Collateral Trust Indenture dated as 
of June 1, 1992 between the Company and Bankers Trust Company, as Trustee 
(the "Indenture Trustee"), as supplemented by the First Supplemental 
Indenture dated 

                                     F-1

as of June 1, 1992, the Second Supplemental Indenture, dated as of October 1, 
1993, the Third Supplemental Indenture, dated as of  February 1, 1996, and 
the Fourth Supplemental Indenture, dated as of February 1, 1997 (as so 
supplemented, the "Indenture"), and are to be secured by the Company's first 
mortgage bonds (the "First Mortgage Bonds") to be issued pursuant to an 
Indenture of Mortgage dated as of December 1, 1940 from the Company's 
predecessor to The New England Trust Company and Leo W. Huegle (State Street 
Bank and Trust Company and Gerald R. Wheeler, respectively, by succession), 
as Trustees, as heretofore supplemented and modified and as to be further 
supplemented by a Thirty-fifth Supplemental Indenture dated as of February 1, 
1997 (the "Supplemental First Mortgage Indenture" and such Indenture of 
Mortgage, as so supplemented and modified, the "First Mortgage Indenture").  
As counsel for the Company, we advise you as follows:

    We have examined the restated Articles of Organization of the Company and
all amendments thereto (the "Charter"), the Bylaws of the Company as now in
effect, resolutions of the Board of Directors of the Company, the final form of
each of the First Mortgage Bonds, the First Mortgage Indenture, the Supplemental
First Mortgage Indenture, the Indenture, the Distribution Agreement, the
Decision and Order issued by the California Public Utilities Commission (the
"CPUC") on August 11, 1995 (Decision ("D.") 95-08-045), Officer's Certificates
duly executed by an officer of the Company, and such other records, instruments
and agreements as we have deemed appropriate for purposes of this opinion. 

     In issuing the opinions expressed herein, we have also assumed (1) that 
the total aggregate principal amount of issuances of debt securities and 
guaranties, including the Debt Securities, to be issued by the Company 
pursuant to the authority granted to it by Decision No. 95-08-045 of the 
Public Utilities Commission of the State of California (the "CPUC") will 
not exceed One Hundred Fifteen Million Dollars ($115,000,000), and (2) that 
the Debt Securities are being issued pursuant to the authority granted to the 
Company under CPUC Decision No. 95-08-045.

     In our examination of the records, instruments and agreements referred to
above, we have assumed the genuineness and authenticity of all signatures; the
accuracy and authenticity of all records, instruments, and agreements submitted
to us as originals; the conformity to originals of all documents submitted to us
as copies; the authenticity of the originals of such copies; the accuracy,
completeness, and authenticity of certificates of public officials and others as
of the date hereof; and the due execution and delivery pursuant to due
authorization thereof by, and the validity and binding effect thereof on, each
party thereto other than the Company.  As to certain issues of fact, we have
relied upon the above-mentioned Officer's Certificates.

     We have made such examination of law as in our judgment is necessary or
appropriate for purposes of this opinion.  We do not, however, for the purposes
of this opinion, purport to be qualified to pass upon, and express no opinion as
to, the laws of any jurisdiction other than the State of California and the
United States of America.

     Based upon and subject to the foregoing, and subject to the qualifications
set forth herein, we are of the opinion that:

     1.   The Company is duly qualified and in good standing as a foreign
corporation under the laws of the State of California and is duly qualified to
hold property and to transact an electric public utility business in the State
of California.

     2.   The Decision and Order dated August 11, 1995 (D. 95-08-045) of the
CPUC remain in full force and effect in the form issued and no other
authorization, approval or other action by, and no notice to or filing or
registration with, any governmental authority or regulatory body of the State of
California is required for the due execution, delivery and performance by the
Company of the First Mortgage Bonds, the Indenture, the Supplemental First
Mortgage Indenture, or the Distribution Agreement.

     3.   The First Mortgage Bonds, the First Mortgage Indenture and the
Supplemental First Mortgage Indenture (the "First Mortgage Documents") are
enforceable in accordance with their terms and under the laws of California. 
However, no opinion is given with respect to the effect of applicable
bankruptcy, insolvency, reorganization or other similar laws affecting the
rights of creditors generally; and no opinion is given with respect to the
effect of rules of law governing specific performance, injunctive relief and
other equitable remedies whether or not equitable remedies are sought, including
without limitation the effect of court cases that have held that certain
provisions of agreements are unenforceable where enforcement would violate the
creditor's implied covenant of good faith and fair dealing or where it cannot be
demonstrated that enforcement is reasonably necessary for the protection of the
security.  However, in our opinion, such rules of law and court cases do not
render the First Mortgage Documents invalid as a whole and there exist, in the
First Mortgage Documents or pursuant to applicable law, legally adequate
remedies for a realization of the principal benefits and/or security intended to
be provided by the First Mortgage Documents.

     We call your attention to certain laws of general application in California
affecting the rights and remedies of creditors, which include, without
limitation, the prohibition against unilateral right of entry in the event of
default of the debtor, limitations on the form of action necessary to enforce a
debt secured by real property, anti-deficiency judgment laws and the rights of
debtors and junior lien holders to redemption following judicial foreclosure. 
We also call to your attention that the provisions of the First Mortgage
Indenture subjecting to the lien

                                    F-3

thereof after-acquired property of the Company may not be effective in some 
cases prior to the execution, delivery and recording of a supplemental 
indenture specifically subjecting such after-acquired property to the lien of 
the First Mortgage Indenture.  In addition, we call your attention to the 
fact that a purchaser at foreclosure sale or anyone other than the Company 
would probably have to qualify under California law in order to own and 
operate the property of the Company as a public entity.

     4.   The First Mortgage Bonds deposited with the Indenture Trustee and a
new series of bonds designated "First Mortgage Bonds 9% Series NN due 2037"
pledged with the Indenture Trustee as the basis for the issuance of the Notes
constitute legal, valid and binding obligations of the Company, subject, as to
enforcement, to laws relating to or affecting generally the enforcement of
creditors' rights, including, without limitation, bankruptcy and insolvency
laws, and to general principles of equity and will be entitled to the security
afforded by the First Mortgage Indenture equally and ratably with the securities
outstanding thereunder.

     5.   The First Mortgage Indenture (or appropriate financing statements)
have been duly recorded or filed in all places in the State of California where
such recording or filing is necessary to perfect the lien of the First Mortgage
Indenture as a lien on the security interest in both real and personal property
of the Company subjected thereto that is located in the State of California. 
Notwithstanding the foregoing, (i) we express no opinion regarding the lien of
the First Mortgage Indenture as against franchises, permits and other personal
property which, under California law, may not be made subject to a personal
property lien, and (ii) we express no opinion as to the perfection of the
security interest in any Personal Property in which, under the provisions of the
California Uniform Commercial Code, a security interest cannot be perfected by
filing a financing statement.

     6.   No taxes (as distinguished from filing and recordation fees) are
payable to the State of California or any subdivision or agency thereof in
connection with the execution and delivery of the First Mortgage Bonds or the
Supplemental First Mortgage Indenture.

     The opinions set forth above are given in our capacity as California
counsel to the Company only.  We do not opine as to matters of New York or
Nevada law, nor as to matters of federal public utilities or environmental law,
nor as to matters of law of any other State.

     (4)  subsequent to the date of the most recent audited financial statements
          incorporated by reference in the Prospectus, neither the Company nor

          any development involving a prospective material adverse change, in or
          affecting particularly the capital stock or long-term debt of the
          Company or any of its subsidiaries or the business, financial

    The letter of the Company's independent accountants will state in effect 
that:

      (1)  They are independent certified public accountants with respect to 
the Company and its subsidiaries within the meaning of the Act and the Rules 
and Regulations.

      (2)  In their opinion, the financial statements audited by them and 
incorporated by reference in the Prospectus comply as to form in all material 
respects with the applicable accounting requirements of the Act and the Rules 
and Regulations.

      (3)  On the basis of procedures referred to in such letter, including a 
reading of the latest available interim financial statements of the Company 
and inquiries of officials of the Company responsible for financial and 
accounting matters, nothing caused them to believe that:

            (a)  any material modifications should be made to the 
      unaudited condensed consolidated financial statements incorporated 
      by reference in the Prospectus for them to be in conformity with 
      generally accepted accounting principles;
      
            (b)  the unaudited condensed consolidated financial 
      statements incorporated by reference in the Prospectus do not 
      comply as to form in all material respects with the applicable 
      accounting requirements of the Securities Exchange Act of 1934 as 
      it applies to Form 10-Q and the related published rules and 
      regulations;
      
            (c)  at the date of the latest available internal balance 
      sheet of the Company, there was any change in the capital stock, 
      notes payable or long-term debt or any decrease in the net assets 
      of the Company, or, at a subsequent specified date not more than 
      five days prior to the date of such letter, there was a change in 
      the capital stock, notes payable or long-term debt of the Company, 
      in each case as compared with the amounts shown in the most recent 
      balance sheet of the Company incorporated by reference in the 
      Prospectus, except for (i) increases in capital stock resulting 
      from the issuance of shares pursuant to employee benefit plans and 
      the Company's Common Stock Investment Plan, (ii) decrease in 
      long-term debt resulting from amortization of debt premium or 
      increases in long-term debt premium or increases in long-term debt 
      resulting from draw-downs of funds held in trust, (iii) decreases 
      in net assets resulting from the declaration of dividends, (iv) 
      changes or decreases which the Prospectus discloses have occurred 
      or may occur and (v) such other changes or decreases as may be set 
      forth in such letter; or
      
            (d)  at the date of the latest available internal balance 
      sheet of the Company, there was any decrease, as compared with the 
      most recent twelve-month period for which operating revenues and 
      net income are included or incorporated by reference in the 
      Prospectus, in such amounts, except in all cases for changes or 
      decreases which the Prospectus discloses have occurred or as may be 
      set forth in such letter.
      

      (4)  In addition to their examination referred to in their report in 
the Registration Statement and Prospectus and the procedures referred to in 
(3) above, they have carried out certain other specified procedures, not 
constituting an audit, with respect to the dollar amounts, percentages and 
other financial information (in each case to the extent that such dollar 
amounts, percentages and other financial information, either directly or by 
analysis or computation, are derived from the general accounting records of 
the Company) as requested by the Agents (or Agents' counsel), which appear in 
the Company's annual report on Form 10-K for its most recent fiscal year 
under the caption "Business" in Item 1 and Item 7 "Management's Discussion 
and Analysis of Financial Condition and Results of Operations" and have found 
such dollar amounts, percentages and financial information to be in agreement 
with the accounting records of the Company.

    BUT IN TRUST, NEVERTHELESS, for the equal pro rata benefit, security and

and except as provided in Section 10.29 of the Original Indenture, so that the
principal and interest of every such Bond shall be equally and ratably secured

the performance of and the compliance with the covenants and conditions of said
Bonds and of the Indenture, and upon the trusts and for the uses and purposes
and subject to the covenants, agreements, provisions and conditions hereinafter
set forth and declared; it being hereby agreed as follows, to wit:


                                      ARTICLE 1

                        Description of Bonds of the NN Series

     Section 1.01.    Establishment of Bonds of the NN Series.  There shall 
be and hereby is established a new series of Bonds to be issued under and 
secured by the Indenture and to be designated as the Company's "First 
Mortgage Bonds, 9% Series NN due 2037" (herein sometimes referred to as 
"Bonds of the NN Series").

     Section 1.02.    Terms of Bonds of the NN Series.  The Bonds of the NN 
Series shall be evidenced by a single registered Bond in the principal amount 
and denomination of Thirty-five Million Dollars ($35,000,000) due February 1, 
2037; it shall bear interest at the rate per annum 

                                      10

<PAGE>

shown in its title, payable semi-annually on February 1 and August 1 of each 
year, commencing August 1, 1997. Interest on the Bonds of the NN Series shall 
be computed on the basis of a 360-day year of twelve 30-day months.  The 
Bonds of the NN Series shall be dated as provided in Section 2.08 of the 
original Indenture as modified by Section 2.03 of the Twelfth Supplemental 
Indenture.

    The single Bond of the NN Series shall be numbered 1 and shall upon
issuance be delivered by the Company to and registered in the name of the
Indenture Trustee and thereafter shall not be sold, assigned, pledged,
mortgaged, transferred or otherwise disposed of except as required to effect (a)
an assignment to a successor Indenture Trustee under the Collateral Trust
Indenture or (b) a surrender to the Trustee (i) to effect an exchange, in
accordance with applicable law, in connection with any Federal or State
bankruptcy, insolvency, reorganization or similar proceeding involving the
Company, (ii) to effect an exchange by the Company with the Indenture Trustee of
any Mortgage Bonds (as defined in the Collateral Trust Indenture) upon payment
or deemed payment or other satisfaction and discharge of a portion of any
Mortgage Bonds, (iii) to effect a surrender or an exchange of any Mortgage Bonds
pursuant to Section 406 or 503 of the Collateral Trust Indenture or (iv) to
obtain the final payment due on any Mortgage Bonds as required by the terms of
the Indenture.  Bonds issued upon any such transfer or surrender shall be
numbered from 2 upwards and issued to the transferee or person surrendering the
same for a like principal amount, less the principal amount of such bond that
has been paid, deemed to have been paid or otherwise satisfied and discharged or
surrendered for cancellation pursuant to Section 406 or 503 of the Collateral
Trust Indenture.

    It is expected that the Company, pursuant to the Collateral Trust
Indenture, will furnish directly to the Indenture Trustee at its principal
corporate trust office all funds required for any and all payments of principal
of, and interest and premium on, Securities.  Any such payment may be made in
any coin or currency of the United States which is legal tender for the payment
of public and private debts.  The obligation of the company to make any payment
of the principal of or interest on the portion of the Bond of the NN Series that
is designated as Designated Mortgage Bonds (as such term is defined in the
Collateral Trust Indenture and hereinafter called "Designated Mortgage Bonds"),
whether at its stated maturity or upon redemption (including any redemption
pursuant to Section 404 of the Collateral Trust Indenture), shall be fully or
partially, as the case may be, deemed to have been paid or otherwise satisfied
and discharged to the extent that at the time any such payment shall be due, the
then due principal of (and premium, if any) or interest on the Securities to
which such Designated Mortgage Bonds relate shall have been fully or partially
paid, deemed to have been paid or otherwise satisfied and discharged.  In
addition, such obligation to make any payment of the principal of or interest on
the portion of the Bond of the NN Series that is designated as Designated
Mortgage Bonds at any time shall be deemed to have been satisfied and discharged
to the extent that the amount of the Company's obligation to make any payment of
the principal of or interest on the portion of the Bond of the NN Series that is
designated as Designated Mortgage Bonds exceeds the obligation of the Company at
that time to make any payment on the applicable Redemption Date or Stated
Maturity (each as defined in the Collateral Trust Indenture) of the principal of
(and premium, if any) or interest on the Securities to which such portion of the
Bond of the NN Series that is designated as Designated Mortgage Bonds relates. 

                                      11
<PAGE>

The obligation of the Company to make any payment of the principal of or
interest on the Bond of the NN Series other than the portion that is designated
as Designated Mortgage Bonds shall be deemed to have been satisfied and
discharged in full at the time any such payment shall be stated to be due.

    Unless payment then is or has been made pursuant to the next preceding
paragraph, payment of the principal of, and premium, if any, and interest on the
single Bond of the NN Series shall be made in any coin or currency of the United
States which at the time of payment is legal tender for the payment of public
and private debts at the principal corporate trust office of the Indenture
Trustee on or prior to the business day preceding the due date for such payment.
Any such payment of principal, premium and interest shall be credited as and
used to make a corresponding payment of principal, premium and interest on the
Securities.

    The Trustees may conclusively presume that the obligation of the Company to
pay the principal of and premium, if any, and interest on the Bond of the NN
Series as the same shall become due and payable at maturity or upon redemption
shall have been duly and punctually paid or deemed to have been paid or
otherwise satisfied and discharged in full unless and until it shall have
received notice in writing to the contrary from the Indenture Trustee,
specifying the amount of funds required to make such payment after giving effect
to Section 403(a) of the Collateral Trust Indenture.

    The Indenture Trustee, by acceptance of the single Bond of the NN Series,
shall agree to make the notations on the Schedule of Designations and
Prepayments required by the Collateral Trust Indenture and to surrender said
Bond to the Trustee upon the circumstances set forth in Section 406 or 503 of
the Collateral Trust Indenture.

    If any of the following events of default occurs under Section 601 of the
Collateral Trust Indenture, it shall be deemed to be the corresponding default
under Section 10.01 of the Indenture as hereafter provided: (i) default in the
payment of any interest upon any Security when such interest becomes due and
payable shall be deemed to be a default, under Section 10.01(a) of the
Indenture, in the due and punctual payment of a like amount of interest on the
Bond of the NN Series, (ii) default in the payment of the principal of (or
premium, if any, on) any Security at the stated maturity thereof or upon
redemption thereof shall be deemed to be a default, under Section 10.01(b) of
the Indenture, in the due and punctual payment of a like amount of principal of
the Bond of the NN Series, (iii) default in the deposit of any sinking fund
payment when and as due by the terms of a Security shall be deemed to be a
default under Section 10.01(d) of the Indenture, (iv) a default in the
performance, or breach, of any covenant or warranty of the Company as described
in Section 601(4) of the Collateral Trust Indenture shall be deemed to be a
default under Section 10.01(d) of the Indenture, (v) the occurrence of an event
described in Section 601(5) of the Collateral Trust Indenture shall be deemed to
be a default under Section 10.01(e) of the Indenture, (vi) the occurrence of an
event described in Section 601(6) of the Collateral Trust Indenture shall be
deemed to be a default under Section 10.01(f) of the Indenture and (vii)
occurrence of an event of default provided in an indenture 

                                      12
<PAGE>

supplemental to the Collateral Trust Indenture shall be deemed to be a 
default under Section 10.01(d) of the Indenture.

    Any notice affecting or relating to the Bonds of the NN Series required 
or permitted to be given under the Indenture may be given by mailing the same 
by first class mail, postage prepaid, to the Indenture Trustee at its address 
as the same appears on the Bond Register for the Bonds of the NN Series.  The 
certificate of the Trustee that such mailing has been effected shall be 
conclusive evidence of compliance with the requirements of Section 4.02 and 
of Section 16.08 of the Original Indenture as modified by Section 2.07 of the 
Twelfth Supplemental Indenture, whether or not the Indenture Trustee receives 
such notice.

    The Trustee hereunder shall, by virtue of its office as such Trustee, be
the Registrar and Transfer Agent of the Company for the purpose of registering
and transferring Bonds of the NN Series, and shall maintain a bond register for
the Bonds of the NN Series.

     Section 1.03.    Prepayment Provisions of the Bonds of the NN Series.  
The Bond of the NN Series shall be redeemable at the option of the Company at 
any time, but only to the extent that such Bond of the NN Series is (i) a 
Designated Mortgage Bond which the Company has incurred the obligation under 
the Collateral Trust Indenture to redeem, or (ii) not a Designated Mortgage 
Bond, and shall not otherwise be redeemable pursuant to the requirements of 
the Indenture, except pursuant to the provisions of clause 2 of Section 6.05 
of the Original Indenture.

    In the event of a redemption in accordance with the provisions of the
preceding paragraph, the Indenture Trustee shall forthwith make notation of the
principal amount of the Bond of the NN Series so redeemed on the Schedule of
Designations and Prepayments printed thereon, and shall promptly notify the

    SIERRA PACIFIC POWER COMPANY, a corporation of the State of Nevada
(hereinafter called the "Company"), for value received, hereby promises to pay
to  ____________________, as trustee (with its successors as such, the
"Indenture Trustee") under that certain Collateral Trust Indenture, dated as of
June 1, 1992, as supplemented (as so supplemented, the "Collateral Trust
Indenture"), between the Company and the Indenture Trustee, providing for the
issuance from time to time of the Company's collateral trust notes (the
"Securities"), to be issued in one or more series or tranches as in the
Collateral Trust Indenture provided, on February 1, 2037, for the ratable
benefit of the Holders from time to time of the series or tranches of
outstanding Securities for which portions of this Bond are designated as
described below, the sum of Thirty-five Million Dollars, and to pay to the
Indenture Trustee interest thereon from February 1, 1997 or the most recent
February 1 or August 1 to which interest has been paid or deemed to have been
paid or otherwise satisfied and discharged, at the rate of 9% per annum on
February 1 and  August 1 in each year, commencing August 1, 1997, until the
Company's obligation with respect to the payment of such principal shall have
been discharged.  Notwithstanding the foregoing, the obligation of the Company
to make any payment of the principal of or interest on the portion of this Bond
that is designated as Designated Mortgage Bonds (as such term is defined in the
Collateral Trust Indenture), whether at maturity, upon redemption (including any
redemption pursuant to Section 404 of the Collateral Trust Indenture) or
otherwise, shall be fully or partially, as the case may be, deemed to have been
paid or otherwise satisfied and discharged to the extent that at the time any
such payment shall be due, the then due principal of (and premium, if any) or
interest on the Securities to which such Designated Mortgage Bonds relate, shall
have been fully or partially paid, deemed to have been paid or otherwise
satisfied and discharged.  In addition, such obligation to make any payment of
the principal of or interest on the portion of this Bond that is designated as
Designated Mortgage Bonds at any time shall be deemed to have been satisfied and
discharged to the extent that the amount of the Company's obligation to make any
payment of the principal of or interest on the portion of this Bond that is
designated as Designated Mortgage Bonds exceeds the obligation of the Company at
that time to make any payment on the applicable Redemption Date or Stated
Maturity (as such terms are defined in the Collateral Trust Indenture)

                                      14

<PAGE>

of the principal of (and premium, if any) or interest on the Securities to 
which such portion of this Bond that is designated as Designated Mortgage 
Bonds relates. The obligation of the Company to make any payment of the 
principal of or interest on this Bond other than the portion that is 
designated as Designated Mortgage Bonds shall be deemed to have been 
satisfied and discharged in full at the time any such payment shall be stated 
to be due.

    The holder of this Bond by acceptance hereof agrees that whenever any
designation or payment on account of the principal of this Bond is made or
occurs under any provision of the indenture referred to below (the "Indenture")
or the Collateral Trust Indenture, the holder hereof shall promptly note on the
Schedule of Designations and Prepayments the date and amount of each such
designation or payment of principal, and shall promptly notify the Trustee of
the amount of each such designation or payment and that the notation of
designation or payment has been duly made, and further agrees to surrender this
Bond to the Trustee for cancellation when all principal of, premium, if any, and
interest on this Bond shall have been duly paid.

    Unless payment then is or has been made pursuant to the second preceding
paragraph, the principal of and interest on this Bond will be paid in lawful
money of the United States of America and will be payable at the principal
corporate trust office of the Indenture Trustee by check or wire transfer to the
order of the Indenture Trustee in Federal funds immediately available at said
office of the Indenture Trustee, in each case on or prior to the business day
preceding the due date for such payment.  The holder of this Bond by acceptance
hereof agrees that any such payment of principal or interest on this Bond shall
be credited as and used to make a corresponding payment of principal, premium or
interest on the Securities.

    This Bond is the single registered bond of the Company of the series
specified in the title hereof, and is issued in the aggregate principal amount
of $35,000,000 in order to secure by the lien of the Indenture hereinafter
mentioned the obligation of the Company to pay duly and punctually the principal
of (and premium, if any) and interest on Outstanding Securities (as defined in
the Collateral Trust Indenture) in accordance with the terms thereof, and the
Collateral Trust Indenture, and evidences the Bonds of a series of an authorized
issue of bonds of the Company, known as First Mortgage Bonds, not limited as to
maximum principal amount except as otherwise provided in the Indenture
hereinafter mentioned, all issued or issuable in one or more series (which
several series may be of different denominations, dates and tenor) under and
equally secured (except insofar as any sinking fund, established in accordance
with the provisions of the Indenture hereinafter mentioned, may afford
additional security for other Bonds of any particular series) by an Indenture of
Mortgage dated as of December 1, 1940, duly executed and delivered by the
Company's predecessor, Sierra Pacific Power Company, a Maine corporation, and
duly assumed by the Company by means of the Tenth Supplemental Indenture
hereinafter mentioned, to The New England Trust Company (now State Street Bank
and Trust Company by succession, herein sometimes called "Trustee"), and Leo W.
Huegle (now Gerald R. Wheeler by succession), as Trustees, as supplemented and
modified by the First Supplemental Indenture, dated as of August 1, 1947, by the
Second Supplemental Indenture, dated as of April 11, 1948, by the Ninth
Supplemental Indenture, dated as of June 1, 1964, by the Tenth Supplemental
Indenture, dated as of March 31, 1965, by the Twelfth Supplemental Indenture,

dated as of July 1, 1967, by the Fourteenth Supplemental Indenture, dated as 
of November 1, 1972, by the Fifteenth Supplemental Indenture, dated as of May 
1, 1974, by the Seventeenth Supplemental Indenture, dated as of July 1, 1976, 
by the Eighteenth Supplemental Indenture, dated as of August 1, 1977, by the 
Nineteenth Supplemental Indenture, dated as of April 1, 1978, and by the 
Twentieth Supplemental Indenture, dated as of October 1, 1978, and as 
supplemented by all other indentures supplemental thereto including a 
Thirty-fifth Supplemental Indenture, dated as of February 1, 1997, executed 
and delivered by the Company (or executed and delivered by its predecessor 
and duly assumed by the Company) to said Trustees, to which Indenture of 
Mortgage and all indentures supplemental thereto (herein sometimes 
collectively called the "Indenture") reference is hereby made for a 
description of the property mortgaged and pledged as security for said bonds, 
the rights and remedies and limitations on such rights and remedies of the 
registered owner of this Bond in regard thereto, the terms and conditions 
upon which said bonds are secured thereby, the terms and conditions upon 
which additional bonds and coupons may be issued thereunder and the rights, 
immunities and obligations of the Trustees under said Indenture; but neither 
the foregoing reference to said Indenture, nor any provision of this Bond or 
of said Indenture, shall affect or impair the obligation of the Company, 
which is absolute, unconditional and unalterable, to pay at the maturity 
herein provided the principal of and premium, if any, and interest on this 
Bond as herein provided.

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

    To the extent permitted and as provided in said Indenture, modifications 
or alterations of said Indenture, or any indenture supplemental thereto, and 
of the bonds issued thereunder and of the rights and obligations of the 
Company and the rights of the bearers or registered owners of the bonds and 
coupons, if any, may be made with the consent of the Company and with the 
written approvals or consents of the bearers or registered owners of not less 
than seventy-five per centum (75%) in principal amount of the bonds 
outstanding, and unless all of the bonds then outstanding under said 
Indenture are affected in the same manner and to the same extent by such 
modification or alteration, with the written approvals or consents of the 
bearers or registered owners of not less than seventy-five per centum (75%) 
in principal amount of the bonds of each series outstanding, provided, 
however, that no such alteration or modification shall, without the written 
approval of or consent of the bearer or registered owner of any bond affected 
thereby, (a) impair or affect the right of such bearer or registered owner to 
receive payment of the principal of and interest on such bond, on or after 
the respective due dates expressed in such bond, or to institute suit for the 
enforcement of any such payment on or after such respective dates, except 
that the holders of not less than seventy-five per centum (75%) in principal 
amount of the bonds outstanding may consent on behalf of the bearers or 
registered owners of all of the bonds to the postponement of any interest 
payment for a period of not exceeding three (3) years from its due date, or 
(b) deprive any bearer or registered owner of the bonds of a lien on the 
                                      16

<PAGE>

mortgaged and pledged property, or (c) reduce the percentage of the principal 
amount of the bonds upon the consent of which modifications may be effected 
as aforesaid.

    If any of the following events occurs under Section 601 of the Collateral
Trust Indenture, it shall be deemed to be the corresponding default under
Section 10.01 of the Indenture as set forth hereafter: (i) default in the
payment of any interest upon any Security when such interest becomes due and
payable shall be deemed to be a default, under Section 10.01(a) of the
Indenture, in the due and punctual payment of a like amount of interest on this
Bond, (ii) default in the payment of the principal of (or any premium, if any,
on) any Security at the stated maturity thereof or upon redemption thereof shall
be deemed to be a default, under Section 10.01(b) of the Indenture, in the due
and punctual payment of a like amount of principal of this Bond, (iii) default
in the deposit of any sinking fund payment, when and as due by the terms of a
Security, shall be deemed to be a default under Section 10.01(d) of the
Indenture, (iv) default in the performance, or breach, of any covenant or
warranty of the Company as described in Section 601(4) of the Collateral Trust
Indenture shall be deemed to be a default under Section 10.01(d) of the
Indenture, (v) occurrence of an event described in Section 601(5) of the
Collateral Trust Indenture shall be deemed to be a default under Section
10.01(e) of the Indenture, (vi) the occurrence of an event described in Section
601(6) of the Collateral Trust Indenture shall be deemed to be a default under
Section 10.01(f) of the Indenture and (vii) occurrence of an event of default
provided in an indenture supplemental to the Collateral Trust Indenture shall be
deemed to be a default under Section 10.01(d) of the Indenture.

    In case an event of default as defined in said Indenture shall occur, the
principal of this Bond may become or be declared due and payable before maturity
in the manner and with the effect provided in said Indenture.  The holders,
however, of certain specified percentages of the bonds at the time outstanding,
including in certain cases specified percentages of bonds of particular series,
may in the cases, to the extent and under the conditions provided in said
Indenture, waive defaults thereunder and the consequences of such defaults.

    This Bond has been issued and delivered to, registered in the name of and
pledged with the Indenture Trustee in trust for the ratable benefit of the
Holders (as defined in the Collateral Trust Indenture) from time to time of the
Outstanding Securities and shall not be sold, assigned, pledged, mortgaged,
transferred or otherwise disposed of except as required to effect (a) an
assignment to a successor Indenture Trustee under the Collateral Trust Indenture
or (b) a surrender to the Trustee (i) to effect an exchange, in accordance with
applicable law, in connection with any Federal or State bankruptcy, insolvency,
reorganization or similar proceeding involving the Company, (ii) to effect an
exchange by the Company with the Indenture Trustee of any Mortgage Bonds (as
defined in the Collateral Trust Indenture) upon payment or deemed payment or
other satisfaction and discharge of a portion of any Mortgage Bonds, (iii) to
effect a surrender or an exchange of any Mortgage Bonds pursuant to Section 406
of the Collateral Trust Indenture or (iv) to obtain the final payment due on any
Mortgage Bonds as required by the terms of the Indenture.  Any such transfer or
surrender shall be made at the principal corporate trust office in Boston,
Massachusetts of the Trustee, upon surrender and cancellation of this Bond. 
Following any such transfer or such surrender of this Bond in part,

                                      17

<PAGE>

and unless such transfer or surrender has been made in connection with the 
satisfaction and discharge of the Collateral Trust Indenture, a new fully 
registered Bond of the same series for a like principal amount, less the 
principal amount of this Bond that has been paid, deemed to have been paid or 
otherwise satisfied and discharged or surrendered for cancellation pursuant 
to Section 406 or 503 of the Collateral Trust Indenture, will be issued to 
such transferee in exchange therefor as provided in the Indenture.  The 
Company hereby waives any right to make a charge for such an exchange or 
transfer of this Bond.  The Company and the Trustees may deem and treat the 
Indenture Trustee as the absolute owner hereof for the purpose of receiving 
payment and for all other purposes.

    The Trustees may conclusively presume that the obligation of the Company to
pay the principal of and interest on the Bond of this series as the same shall
become due and payable shall have been duly and punctually paid or deemed to
have been paid or otherwise satisfied and discharged in full unless and until it
shall have received notice in writing to the contrary from the Indenture
Trustee, specifying the amount of funds required to make such payment after
giving effect to Section 403(a) of the Collateral Trust Indenture.

    This Bond shall be redeemable at the option of the Company at any time, but
only to the extent that this Bond is (i) a Designated Mortgage Bond which the
Company has incurred the obligation under the Collateral Trust Indenture to
redeem, or (ii) not a Designated Mortgage Bond, and shall not otherwise be
redeemable pursuant to the requirements of the Indenture, except as provided in
this paragraph.  In case all or substantially all of the electric properties of
the Company are sold to or taken through the exercise of the right of eminent
domain or the right to purchase by any municipal or governmental body or agency,
the principal of this Bond will, upon receipt by the Company of payment or
compensation, become due and payable before maturity at the principal amount
thereof and accrued interest thereon, all as provided in said Indenture.

    In the event of a redemption in accordance with the provisions of the
preceding paragraph, the Indenture Trustee shall forthwith make notation of the
principal amount of this Bond so redeemed on the Schedule of Designations and
Prepayments printed hereon, and shall promptly notify the Trustee of the amount
of such payment and that notation of such payment has been duly made.

    The holder of this Bond, pursuant to the terms of Section 402 of the
Collateral Trust Indenture, hereby waives its right, pursuant to Section 4.03 of
the Indenture, to the deposit of moneys for redemption before the redemption
date.

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

                                      18

<PAGE>

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

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

    It is part of the contract herein contained that each registered owner
hereof by the acceptance hereof waives all right of recourse to any personal
liability of any incorporator, stockholder, officer or director, past, present
or future, of the Company, as such, or of any predecessor or successor
corporation, howsoever arising, for the collection of any indebtedness
hereunder; and as a part of the consideration for the issue hereof releases from
all such liability each such incorporator, stockholder, officer or director, all
as provided in said Indenture.

    Each registered owner hereof by his acceptance hereof waives any right to 
exchange any unpaid portion of this Bond for another Bond under Section 4.01 
of the Indenture.

    This Bond has not been registered under the Securities Act of 1933, as
amended, and may not be offered or sold in contravention of said Act.

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

OTHER PROVISIONS:



    Sierra Pacific Power Company, a Nevada corporation ("Issuer" or the 
"Company," which terms include any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to CEDE &
CO., or registered assigns, the principal sum of **_________ MILLION DOLLARS**
on the Stated Maturity Date specified above (except to the extent redeemed or
repaid prior to the Stated Maturity Date), and to pay interest thereon at the
Interest Rate per annum specified above, until the principal hereof is paid or
duly made available for payment.  Reference herein to "this Note," "hereof,"
"herein" and comparable terms shall include an Addendum hereto if an Addendum 
is specified above.

    The Company will pay interest on each Interest Payment Date specified 
above, commencing on the first Interest Payment Date next succeeding the 
Original Issue Date specified above, and on the Stated Maturity Date or any 
Redemption Date or Optional Repayment Date (as defined below) (the date of 
each such Stated Maturity Date, Redemption Date and Optional Repayment Date 
and the date on which principal or an installment of principal is due 



<PAGE>

and payable by declaration of acceleration pursuant to the Indenture being 
referred to hereinafter as a "Maturity" with respect to principal payable on 
such date); PROVIDED, HOWEVER, that if the Original Issue Date is between a 
Regular Record Date (as defined below) and the next succeeding Interest 
Payment Date, interest payments will commence on the second Interest Payment 
Date succeeding the Original Issue Date.  Except as provided above, interest 
payments will be made on the Interest Payment Dates shown above.  Unless 
otherwise specified above, the "Regular Record Date" shall be the date 15 
calendar days (whether or not a Business Day) prior to the applicable 
Interest Payment Date. Interest on this Note will accrue from and including 
the most recent Interest Payment Date to which interest has been paid or duly 
provided for or, if no interest has been paid, from the Original Issue Date 
specified above, to, but excluding such Interest Payment Date.  If the

from and after such Maturity or Interest Payment Date.  The interest so 
payable and punctually paid or duly provided for on any Interest Payment Date 
will as provided in the Indenture be paid to the Person in whose name this 
Note (or one or more Predecessor Securities) is registered at the close of 
business on the Regular Record Date for such Interest Payment Date.  Any such 
interest which is payable, but not punctually paid or duly provided for on 
any Interest Payment Date (herein called "Defaulted Interest"), shall 
forthwith cease to be payable to the registered Holder on such Regular Record 
Date, and may be paid to the Person in whose name this Note (or one or more 
Predecessor Securities) is registered at the close of business on a Special 
Record Date for the payment of such Defaulted Interest to be fixed by the 
Trustee, notice whereof shall be given to the Holder of this Note not less 
than 10 days prior to such Special Record Date, or may be paid at any time in 
any other lawful manner, all as more fully provided in the Indenture.

    Payment of the principal of and interest on this Note will be made at the 
Office or Agency of the Company maintained by the Company for such purposes, 
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; PROVIDED, 
HOWEVER, that at the option of the Company, payment of interest may be made 
by check mailed to the address of the Person entitled thereto as such address 
shall appear in the Security Register; and PROVIDED, FURTHER, that AT THE 
OPTION OF THE COMPANY, the Holder of this Note may be entitled to receive 
payments of principal of and interest on this Note by wire transfer of 
immediately available funds if appropriate wire transfer instructions have been

received by the Trustee not less than 15 days prior to the applicable payment 
date.

thereon payable to the date of repayment.  For this Note to be repaid in

continuing, the principal of all the Notes may be declared due and payable in
the manner and with the effect provided in the Indenture.

    The Indenture permits, with certain exceptions as therein provided, the 
amendment thereof and the modification of the rights and obligations of the 
Company and the Rights of the Holders of the Securities of each series to be 
affected thereby at any time by the Company and the Trustee with the consent 
of the Holders of 66 2/3% in aggregate principal amount of the Outstanding

provisions permitting the Holders of specified percentages in aggregate 
principal amount of the Securities of each series at the time Outstanding, on 
behalf of the Holders of all the Securities of such series, 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 Note shall be conclusive and binding 
upon such Holder and upon all future Holders of this Note and of any Note 
issued upon the registration of transfer hereof or in exchange herefor or in 
lieu hereof whether or not notation of such consent or waiver is made upon 
this Note.

    No reference herein to the Indenture and no provision of this Note or of 
the Indenture shall alter or impair the obligation of the Company, which is 
absolute and unconditional, to pay the principal of and interest on this Note

authorized in writing, and thereupon one or more new Notes of authorized 
denominations and for the same aggregate principal amount, will be issued to 
the designated transferee or transferees.



<PAGE>

coupons in denominations of $10,000 and integral multiples of $1,000 in 
excess thereof.  Thereafter, the Notes may be transferred or exchanged, in 
accordance with the terms of the Indenture, for Notes in integral multiples 
of $1,000.  As provided in the Indenture and subject to certain limitations 
therein set forth, the Notes are exchangeable for a like aggregate principal 
amount of Notes as requested by the Holder surrendering the same.

    No service charge shall be made for any such registration of transfer or

any tax or other governmental charge payable in connection therewith.
