Dated as of May 31, 2022
To the Purchasers Listed in
the Attached Schedule A:
Ladies and Gentlemen:
Sierra Pacific Power Company, a corporation of the State of Nevada (the “Company”), agrees with each of the institutional investors listed in the attached Schedule A (the “Purchasers”) to this Bond Purchase Agreement (this “Agreement”) as follows:
SECTION 1.Authorization of Bonds.
The Company will authorize the issue and sale of $250,000,000 aggregate principal amount of its General and Refunding Mortgage Bonds, 4.71% SERIES DUE 2052 (the “Bonds”).  The Bonds will be issued under and in accordance with and secured by the General and Refunding Mortgage Indenture, dated as of May 1, 2001 (the “Mortgage Indenture”), from the Company to The Bank of New York Mellon Trust Company, N.A. (as successor to The Bank of New York), as trustee (the “Trustee”), as amended and supplemented through the date hereof and as further amended and supplemented by the Company Supplemental Indenture, dated as of May 31, 2022 (which incorporates the terms of the Officer’s Certificate, dated as of May 31, 2022 (the “Officer’s Certificate”)) (together with the Officer’s Certificate, the “Supplemental Indenture”), establishing the terms of the Bonds (the Mortgage Indenture, as so amended and supplemented, being hereinafter called the “Mortgage”).  The Supplemental Indenture shall be substantially in the form set out in Exhibit C hereto, with such changes therefrom, if any, as may be approved by the Purchasers and the Company.  Certain capitalized terms used herein shall have the respective meanings ascribed to such terms in the Mortgage unless otherwise defined in Schedule B to this Agreement or the context hereof shall otherwise require.
SECTION 2.Sale and Purchase of Bonds.
Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser and each Purchaser will purchase from the Company, at the Closing provided for in Section 3, Bonds in the principal amount specified opposite such Purchaser’s name in Schedule A to this Agreement at the purchase price of 100% of the principal amount thereof.  The obligations of each Purchaser hereunder are several and not joint obligations and each Purchaser shall have no obligation and no liability to any Person for the performance or nonperformance by any other Purchaser hereunder.
SECTION 3.Closing.
The sale and purchase of the Bonds to be purchased by each Purchaser shall occur at the offices of Latham & Watkins LLP, 1271 Avenue of the Americas, New York, New York 10020, at 10:00 a.m., Eastern time, at a closing (the “Closing”) on May 31, 2022.

If at the Closing the Company shall fail to tender such Bonds to a Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to a Purchaser’s satisfaction, such Purchaser shall, at such Purchaser’s election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Purchaser may have by reason of such failure or such nonfulfillment. 
Subject to the consummation of the Merger, on the Merger Closing date, the aggregate principal amount of Bonds held by each Purchaser shall automatically be exchanged for an equal aggregate principal amount of Nevada Power Exchange Bonds issued under the Nevada Power Supplemental Indenture.

SECTION 5.Representations and Warranties of the Company.
The Company represents and warrants to each Purchaser that:
Section 5.1Organization; Power and Authority.  The Company is a corporation duly organized and validly existing and in good standing under the laws of the State of Nevada, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, taken as a whole, have a Material Adverse Effect.  The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement, the Bonds and the other Bond Documents and to perform the provisions hereof and thereof.
Section 5.2Authorization, Etc.; Matters Relating to the Mortgage.  
(a)This Agreement and the Bonds have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Bond will constitute a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws affecting creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).
(b)The Mortgage has been duly authorized by the Company; the Mortgage (excluding the Supplemental Indenture) has been, and, at the Closing, the Mortgage will be, duly executed and delivered by the Company; and the Mortgage (excluding the Supplemental Indenture) constitutes, and, at the Closing, the Mortgage will constitute, the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting mortgagees’ and other creditors’ rights and to general equity principles and except to the extent that the law of the jurisdictions in which the mortgaged property is located may limit or deny certain remedial provisions of the Mortgage.
(c)The Bonds have been duly authorized by the Company and, at the Closing, will have been duly executed by the Company; and, when the Bonds have been (i) authenticated and delivered by the Trustee under the Mortgage and (ii) issued and delivered by the Company against payment of the purchase price therefor as provided in this Agreement, the Bonds will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles, and will be entitled to the benefits of the Mortgage ratably with all other securities outstanding thereunder.
(d)The Mortgage (excluding the Supplemental Indenture) constitutes, and, at the Closing, the Mortgage will constitute, a valid first lien upon and security interest in the interest held by the Company in its property covered by the Mortgage, subject to no mortgage, pledge, lien, security interest, charge or other encumbrance of any kind (collectively, “Liens”) prior to the lien of the Mortgage except “excepted encumbrances” (as defined in the Mortgage) and other Liens permitted by the Mortgage and to such other matters as do not materially affect the security for the Bonds.  The Mortgage (excluding the Supplemental Indenture) by its terms effectively subjects, and, at and after the Closing, the Mortgage by its terms will effectively

Section 5.3Disclosure.  The Company, through its agents, J.P. Morgan Securities LLC and KeyBanc Capital Markets, Inc., has delivered to each Purchaser a copy of an Investor Presentation, dated May 12, 2022 (the “Presentation”), relating to the transactions contemplated hereby. The Exchange Act Reports (including the financial statements included therein) and the other documents, certificates or other writings identified in Schedule 5.3 (the “Additional Disclosure Documents”, this Agreement, the Presentation, the Exchange Act Reports and the Additional Disclosure Documents being referred to collectively as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made.  Other than as set forth in the Disclosure Documents, since December 31, 2021, there has been no change in the financial condition, results of operations, business or properties of the Company except changes that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 5.5Financial Statements; Independent Auditors.

Subject to the preceding sentence, this Agreement, the Bonds and the other Bond Documents embody the entire 

26

agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.
SECTION 17.Amendment and Waiver.
Section 17.1Requirements.  In addition to and not in limitation of any rights of a holder of a Security to amend or waive any provision of the Mortgage, or consent to an amendment or waiver thereof, this Agreement may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser in writing, and (b) no amendment or waiver may, without the written consent of the holder of each Bond at the time outstanding, reduce the rate or change the time of payment or method of computation of the Make-Whole Amount or amend any of Sections 17 or 20 or change the percentage of the principal amount of the Bonds the holders of which are required to consent to any amendment or waiver.
Section 17.2Solicitation of Holders of Bonds.
(a)Solicitation.  The Company will provide each holder of the Bonds (and, until the Closing provided for in Section 3, each Purchaser) (irrespective of the amount of Bonds then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required as set forth in Article XIV of the Mortgage, to enable such holder (and Purchaser, if applicable) to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Bond Documents.  The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder (and Purchaser, if applicable) of outstanding Bonds promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders (and Purchasers, if applicable) of Bonds.
(b)Payment.  The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Bonds (and, until the Closing provided for in Section 3, each Purchaser) as consideration for or as an inducement to the entering into by any holder (and Purchaser, if applicable) of Bonds or any waiver or amendment of any of the terms and provisions hereof or any Bond unless such remuneration is concurrently paid, or security is concurrently granted or other credit support is concurrently granted, on the same terms, ratably to each holder (and Purchaser, if applicable) of Bonds then outstanding even if such holder (or Purchaser, if applicable) did not consent to such waiver or amendment.
(c)Consent in Contemplation of Transfer.  Any consent given pursuant to this Section 17 by a holder of a Bond that has transferred or has agreed to transfer its Bond to (i) the Company, (ii) any Subsidiary or any other Affiliate or (iii) any other Person in connection with, or in anticipation of, such other Person acquiring, making a tender offer for or merging with the Company and/or any of its Affiliates, in each case in connection with such consent, shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Bonds that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such holder.

27

Section 17.3Binding Effect, Etc.  Any amendment or waiver consented to as provided in this Section 17 applies equally to all Purchasers and holders of Bonds and is binding upon them and upon each future holder of any Bond and upon the Company without regard to whether such Bond has been marked to indicate such amendment or waiver.  No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon.  No course of dealing between the Company and any Purchaser or holder of any Bond nor any delay in exercising any rights hereunder or under any Bond shall operate as a waiver of any rights of any Purchaser or holder of such Bond.  As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.
Section 17.4Bonds Held by Company, Etc.  Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Bonds then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or have directed the taking of any action provided herein to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Bonds then outstanding, Bonds directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.
Section 17.5Governing Documents.  Anything in this Agreement to the contrary notwithstanding, any amendment, supplement or other modification of or to the Bonds, the Supplemental Indenture and/or the Mortgage, or any waiver of any covenant or other obligation thereunder or of any Default or Event of Default set forth therein, and the effect of any thereof, shall be governed solely by the provisions of the Mortgage.
SECTION 18.Notices.
All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service (charges prepaid).  Any such notice must be sent:
(i)if to any Purchaser or its nominee, to such Purchaser or nominee at the address specified for such communications in Schedule A to this Agreement, or at such other address as such Purchaser or nominee shall have specified to the Company in a notice that satisfies the requirements of this Section 18,
(ii)if to any other holder of any Bond, to such holder at such address as such other holder shall have specified to the Company in a notice that satisfies the requirements of this Section 18, or
(iii)if to the Company, to the Company at its address set forth at the beginning hereof to the attention of Michael Cole, or at such other address as the Company shall have specified to the holder of each Bond in a notice that satisfies the requirements of this Section 18.
Notices under this Section 18 will be deemed given only when actually received.  
SECTION 19.Reproduction of Documents.
This Agreement and all documents relating thereto, including (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by such Purchaser at the Closing (except the Bonds themselves), and (c) financial statements, certificates and other 

28

information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, electronic, digital or other similar process and such Purchaser may destroy any original document so reproduced.  The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence.  This Section 19 shall not prohibit the Company or any other holder of Bonds from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.
SECTION 20.Confidential Information.
For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement or the Bond Documents that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or (d) constitutes financial statements delivered to such Purchaser that are otherwise publicly available.  Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Bonds), (ii) its auditors, financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 20, (iii) any other holder of any Bond or the Trustee, (iv) any Institutional Investor to which it sells or offers to sell such Bond or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person from which it offers to purchase any Security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 20), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the National Association of Insurance Commissioners, securities valuation office or, or any similar organization, or any nationally recognized rating agency that, in each case, requires access to information about such Purchaser’s investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Bonds, this Agreement or the other Bond Documents.  Each holder of a Bond, by its acceptance of a Bond, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement.  On reasonable request by the Company in connection with the delivery to any holder of a Bond of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20.

29

In the event that as a condition to receiving access to information relating to the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Bond is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality undertaking.
SECTION 21.Substitution of Purchaser.
Each Purchaser shall have the right to substitute any one of its Affiliates or another Purchaser or any one of such other Purchaser’s Affiliates (a “Substitute Purchaser”) as the purchaser of the Bonds that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Substitute Purchaser, shall contain such Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations set forth in Section 6.  Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser.  In the event that such Substitute Purchaser is so substituted as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Bonds then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any reference to such Substitute Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Bonds under this Agreement and the other Bond Documents.
SECTION 22.Miscellaneous.
Section 22.1Successors and Assigns.  All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including any subsequent holder of a Bond) whether so expressed or not, except that, subject to Section 1.11 of the Mortgage, the Company may not assign or otherwise transfer any of its rights or obligations hereunder or under the Bonds without the prior written consent of each holder.  Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto and their respective successors and assigns permitted hereby) any legal or equitable right, remedy or claim under or by reason of this Agreement.
Section 22.2Accounting Terms.  All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP.  Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP.  For purposes of determining compliance with this Agreement (including the definition of “Indebtedness”), any election by the Company to measure any financial liability using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.
Section 22.3Severability.  Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any 

30

such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.
Section 22.4Construction.  Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant.  Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.
Defined terms herein shall apply equally to the singular and plural forms of the terms defined.  Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms.  The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.”  The word “will” shall be construed to have the same meaning and effect as the word “shall.”  Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein) and, for purposes of the Bonds, shall also include any such notes issued in substitution therefor pursuant to Section 13, (b) subject to Section 22.1, any reference herein to any Person shall be construed to include such Person’s successors and assigns, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (d) all references herein to Sections and Schedules shall be construed to refer to Sections of, and Schedules to, this Agreement, and (e) any reference to any law or regulation herein shall, unless otherwise specified, refer to such law or regulation as amended, modified or supplemented from time to time.
Section 22.5Counterparts.  This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument.  Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.
Section 22.6Governing Law.  This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.
Section 22.7Jurisdiction and Process; Waiver of Jury Trial.  
(a)The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement, but excluding the Bonds or the other Bond Documents.  To the fullest extent permitted by applicable law, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.
(b)Nothing in this Section 22.6 shall affect the right of any holder of a Bond to serve process in any manner permitted by law, or limit any right that the holders of any of the Bonds may have to bring proceedings against the Company in the courts of any appropriate jurisdiction 

31

or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.
(c)The Company consents to process being served by or on behalf of any holder of Bonds, in any suit, action or proceeding of the nature referred to in Section 22.6(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in Section 18 or at such other address of which the Company shall then have been notified pursuant to said Section.  The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it.  Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service.
(d)The Company agrees, to the fullest extent permitted by applicable law, that a final judgment in any suit, action or proceeding of the nature referred to in Section 22.6(a) brought in any such court shall be conclusive and binding upon it subject to rights of appeal, as the case may be, and may be enforced in the courts of the United States of America or the State of New York (or any other courts to the jurisdiction of which it or any of its assets is or may be subject) by a suit upon such judgment.
(e)THE PARTIES HERETO HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS AGREEMENT, THE BONDS OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH OR THEREWITH. 
[SIGNATURE PAGES FOLLOW]
