Section 3.3.      Investment of Moneys in Funds and Accounts.  Any moneys in any fund or account held by the Trustee with respect to the Bonds shall, to the extent permitted under the Indenture, at the written direction of an Authorized Company Representative, be invested or reinvested by the Trustee as provided in the Indenture.

Section 3.4.      Tax Exempt Status of Bonds.  It is the intention of the Company that interest on the Bonds shall be and remain Tax‐Exempt and to that end the covenants and agreements of the Company in this Section are for the benefit of the Trustee and each and every holder of the Bonds.  The Company covenants and agrees that it has not taken or omitted to take any action, or permitted the taking or omission of any action within its control, and will not take or omit to take any action, or permit the taking or omission of any action within its control, the taking or omission of which, in any case, resulted or would result in interest paid on the Bonds being included in gross income of the holders or beneficial owners of the Bonds for purposes of federal income taxation (other than a holder or beneficial owner who is a “substantial user” of the Project or a “related person” within the meaning of Section 103(b)(13) of the 1954 Code).  The Company covenants that none of the proceeds of the Bonds or the payments to be made under this Agreement, nor any other funds which may be deemed to be proceeds of the Bonds pursuant to Section 148(a) of the Code, will be invested or used in such a way, and that no actions will be taken or not taken, as to cause the Bonds to be treated as “arbitrage bonds” within the meaning of Section 148(a) of the Code.

To secure and provide for the payment of Repayment Installments hereunder, the Company hereby and concurrently herewith issues and delivers to the Trustee its G&R Notes and covenants to maintain the G&R Notes in place during the term of this Agreement as herein and in the Indenture provided.  Payments of Repayment Installments made by the Company pursuant to this Section 4.2(a) shall be considered to be a satisfaction, to such extent, of its obligation to make corresponding payments on the G&R Notes.  The Company agrees that upon the occurrence and continuation of an Event of Default under Section 8.01(c) of the Indenture, the Trustee may demand an immediate 

-9-
4847-5363-8470.4 

mandatory redemption of the G&R Notes.  The Trustee, as holder of the G&R Notes, has waived notice of any such mandatory redemption.
(b)    The Company shall pay to the Trustee amounts equal to the amounts to be paid by the Trustee for the purchase of Bonds pursuant to Article V of the Indenture.  Such amounts shall be paid by the Company to the Trustee in immediately available funds on each day on which a payment of Purchase Price of a Bond which has been tendered (or deemed tendered) shall become due; provided, however, that the obligation of the Company to make any such payment shall be deemed to be satisfied and discharged to the extent moneys held by the Trustee under the Indenture and available therefor, will enable the Trustee to make such payment in full in a timely manner.  If a Credit Facility consisting of a direct pay letter of credit is then in effect for a series of Bonds, any available funds held by the Trustee in the Credit Facility Account for such series in the Purchase Fund pursuant to Section 5.11 of the Indenture, shall be credited against the amount due on such date with respect to the Purchase Price of the Bonds pursuant to this Section.
(c)    The Company agrees to pay to the Trustee (i) the fees of the Trustee for the Ordinary Services rendered by it and an amount equal to the Ordinary Expenses incurred by it under the Indenture and each Tax Agreement, as and when the same become due, and (ii) the reasonable fees, charges and expenses of the Trustee for reasonable Extraordinary Services and Extraordinary Expenses, as and when the same become due, incurred under the Indenture and each Tax Agreement.  The Company agrees that each of the Trustee and the Remarketing Agent, and its officers, agents, servants and employees, shall not be liable for, and agrees that it will at all times indemnify and hold harmless each of the Trustee and the Remarketing Agent, its officers, agents, servants and employees against, any and all losses, costs, charges, expenses, judgments and liabilities created by or arising out of this Agreement, the Indenture or either Tax Agreement, that may be occasioned by any cause (other than the negligence or willful misconduct of the Trustee or the Remarketing Agent, as the case may be, its officers, servants and employees as fully and finally determined by a court of competent jurisdiction).  In case any action shall be brought against the Trustee or the Remarketing Agent in respect of which indemnity may be sought against the Company, the Trustee upon receiving written notice of such action or the Remarketing Agent, as the case may be, shall promptly notify the Company in writing and the Company shall be entitled to assume control of the defense thereof, including the employment of Counsel reasonably satisfactory to the Trustee and the payment of all expenses.  The Trustee or the Remarketing Agent, as the case may be, shall have the right to employ separate Counsel in any such action and participate in the defense thereof, but the fees and expenses of such Counsel shall be paid by the Trustee or the Remarketing Agent, as the case may be, unless (i) the employment of such Counsel has been authorized by the Company, (ii) the Trustee or the Remarketing Agent, as the case may be, has determined in good faith that there may be a conflict of interest of such Counsel retained by the Company between the Company and the Trustee or the Remarketing Agent, as the case may be, in the conduct of such defense, (iii) the Company ceases or terminates the employment of such Counsel retained by the Company or (iv) such Counsel retained by the Company withdraws with respect to such defense.  The Company shall not be liable for any settlement of any such action without its consent (which consent shall not be unreasonably withheld), but if any such action is settled with the consent of the Company or if there be final judgment for the plaintiff in any such action, the Company agrees to indemnify and hold harmless the Trustee or the Remarketing Agent, as the case may be, from and against any 

-10-
4847-5363-8470.4 

loss or liability by reason of such settlement or final judgment.  The Company agrees that the indemnification provided herein shall survive the termination of this Agreement or the Indenture or the resignation or removal of the Trustee or the Remarketing Agent, as the case may be.  For purposes of this Section 4.2(c), the Trustee and the Remarketing Agent are deemed third party beneficiaries of this Agreement.
(d)    The Company agrees to pay all costs incurred in connection with the issuance of the Bonds from sources other than Bond proceeds and the Issuer shall have no obligation with respect to such costs.
(e)    The Company agrees to indemnify and hold harmless the Issuer and any member, officer, official or employee of the Issuer against any and all losses, costs, charges, expenses, judgments and liabilities created by or arising out of this Agreement, the Indenture, any Remarketing Agreement, the Bond Purchase Agreement or any Tax Agreement or otherwise incurred in connection with the issuance of the Bonds.  The Issuer may submit to the Company periodic statements, not more frequently than monthly, for its Administrative Expenses and the Company shall make payment to the Issuer of the full amount of each such statement within 30 days after the Company receives such statement.
(f)    The Company agrees to pay to any Remarketing Agent for a series of Bonds the reasonable fees, charges and expenses of such Remarketing Agent when the same become due and the Issuer shall have no obligation or liability with respect to the payment of any such fees, charges or expenses.  For purposes of this Section 4.2(f), the Remarketing Agent is deemed a third party beneficiary of this Agreement.
(g)    In the event the Company shall fail to make any of the payments required by subsection (a) or (b) of this Section 4.2, the payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid and the Company will pay interest to the extent permitted by law, on any overdue amount at the rate of interest borne by the Bonds on the date on which such amount became due and payable until paid.  In the event the Company shall fail to make any of the payments required by subsection (c), (d), (e) or (f) of this Section 4.2, the payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid, and the Company agrees to make any payment required by subsection (e) of this Section 4.2 with interest thereon to the extent permitted by law at a rate 1% above the rate of interest then charged by the Trustee on 90-day commercial loans to its prime commercial borrowers until paid.  The provisions of this Section shall survive the termination of this Agreement.
Section 4.3.      No Defense or Set-Off.  The obligation of the Company to make the payments pursuant to this Agreement and the G&R Notes shall be absolute and unconditional without defense or set-off by reason of any default by the Issuer under this Agreement or under any other agreement between the Company and the Issuer, by reason of any cancellation of this Agreement and/or the Indenture under the circumstances described in Section 8.11 hereof and Section 12.14 of the Indenture or for any other reason, it being the intention of the parties that the 

-11-
4847-5363-8470.4 

payments required hereunder will be paid in full when due without any delay or diminution whatsoever.
Section 4.4.      Payments Pledged and Assigned.  It is understood and agreed that all payments required to be made by the Company pursuant to Section 4.2 hereof (except payments made to the Trustee or any Remarketing Agent pursuant to Section 4.2(c) hereof, to the Issuer pursuant to Section 4.2(e) hereof, to any Remarketing Agent pursuant to Section 4.2(f) hereof, and to any or all of the Issuer, the Trustee and any Remarketing Agent pursuant to Section 4.2(g) hereof) and certain rights of the Issuer hereunder are pledged and assigned by the Indenture.  The Company consents to such pledge and assignment.  The Issuer hereby directs the Company and the Company hereby agrees to pay or cause to be paid to the Trustee all said amounts except payments to be made to the Issuer pursuant to Sections 4.2(e) and (g) hereof and payments to be made to any Remarketing Agent pursuant to Sections 4.2(c), (f) and (g) hereof.  The Project will not constitute any part of the security for the Bonds, except to the extent that the Trustee as the holder of the G&R Notes has a lien on property under the G&R Indenture.
Section 4.5.      Payment of the Bonds and Other Amounts.  The Bonds and interest and premium, if any, thereon shall be payable solely from (i) Repayment Installments made by the Company to the Trustee under Section 4.2(a) hereof and (ii) other moneys on deposit in the Bond Fund and available therefor.
Payments of principal of, and premium, if any, or interest on, the Bonds with moneys in the Bond Fund on any due date for a Repayment Installment required by Section 4.2(a) hereof shall be credited against the obligation to pay such Repayment Installment to the extent such moneys are available for such purpose.
Whenever any Bonds are redeemable in whole or in part at the option of the Company, the Trustee, on behalf of the Issuer, shall redeem the same upon the request of the Company and such redemption (unless conditional) shall be made from Repayment Installments made by the Company to the Trustee under Section 4.2(a) hereof equal to the redemption price of such Bonds.
Whenever payment or provision therefor has been made in respect of the principal of, or premium, if any, or interest on, all or any portion of the Bonds in accordance with the Indenture (whether at maturity or upon redemption or acceleration or upon provision for payment in accordance with Article XI of the Indenture), Repayment Installments shall be deemed paid to the extent such payment or provision therefor has been made and is considered to be a payment of principal of, or premium, if any, or interest on, such Bonds.  If such Bonds are thereby deemed paid in full, the Trustee shall notify the Company and the Issuer that such payment requirement has been satisfied.  Subject to the foregoing, or unless the Company is entitled to a credit under this Agreement or the Indenture, all payments shall be in the full amount required by Section 4.2(a) hereof.

(iii)    the term of such Credit Facility must extend at least 364 days or to at least the first date on which a replacement Credit Facility could become effective as described in clause (ii) above, whichever is longer; and
(iv)    if such Credit Facility is a direct pay letter of credit, it shall be in the amount of (A) the aggregate principal amount of the Bonds of such series to enable the Trustee to pay (1) the principal of such Bonds at maturity, upon call for redemption prior to maturity or acceleration, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee or the related Remarketing Agent for optional or mandatory purchase pursuant to Article V of the Indenture equal to the aggregate principal amount thereof to the extent remarketing proceeds are not available for such purpose in the related series subaccount of the Remarketing Proceeds Account and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to that portion of the redemption price of such Bonds equal to the principal that would have been payable on such Bonds on the redemption date had such Bonds been redeemed rather than purchased; plus (B) interest to accrue on the Bonds of such series during the term of such Credit Facility (which may be specified for a maximum Interest Accrual Period plus a certain number of days required by each Rating Agency then rating such Bonds to obtain a rating on such Bonds based on such letter of credit, and at a rate up to the Maximum Rate) to enable the Trustee to pay (1) the interest on the Bonds of such series when due, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee or the related Remarketing Agent for optional or mandatory purchase pursuant to Article V of the Indenture equal to the accrued and unpaid interest, if any, on such Bonds to the extent remarketing proceeds are not available for such purpose in the related series subaccount of the Remarketing Proceeds Account and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to that portion of the redemption price of such Bonds equal to the accrued and unpaid interest, if any, that would have been payable 

-13-
4847-5363-8470.4 

on such Bonds on the redemption date had such Bonds been redeemed rather than purchased; plus (C) any redemption premium that may be payable on the Bonds of such series during the term of such Credit Facility in the event of an optional redemption of all of the Bonds of such series to enable the Trustee to pay (1) any such redemption premium upon an optional redemption of such Bonds, (2) the portion of the Purchase Price of the Bonds of such series tendered or deemed to be tendered to the Trustee for mandatory purchase pursuant to Article V of the Indenture equal to the premium that would have been payable on the redemption date had such Bonds been redeemed rather than purchased and (3) the portion of the Purchase Price of the Bonds of such series purchased in lieu of redemption pursuant to Section 4.06 of the Indenture equal to the premium that would have been payable on the redemption date had the Bonds been redeemed rather than purchased.  Notwithstanding the above, any redemption premium that may be payable on the Bonds of a series during the term of a Credit Facility (either as such premium or as a part of the Purchase Price thereof) need not be covered by such Credit Facility so long as it shall be paid with Eligible Moneys on the date, if any, it becomes due and payable and if such coverage is not required by each Rating Agency then rating such Bonds to obtain a rating on such Bonds based on such letter of credit.
(c)    On or prior to the date, if any, of the delivery of a Credit Facility for a series of Bonds to the Trustee pursuant to subsection (a) above that meets the requirements set forth in subsection (b) above, the Company shall cause to be delivered to the Trustee and the Issuer a Favorable Opinion of Bond Counsel addressed to the Trustee and the Issuer.  Upon receipt by the Trustee of any such Credit Facility and the opinion described above, the Trustee shall accept such Credit Facility and surrender any previously held Credit Facility to the Credit Provider thereof for cancellation promptly upon such replacement Credit Facility becoming effective; provided that the previous Credit Provider has honored all demands for payment on any Credit Facility being replaced.

Any such transfer of the Company’s generation assets shall not relieve the Company of any of its obligations under this Agreement.
The Company need not comply with any of the provisions of this Section 5.1 if, at the time of such merger, combination, consolidation, sale of assets, dissolution or reorganization, the Bonds will be defeased as provided in Article XI of the Indenture.

due. The Company may, at its own expense and in its own name in good faith contest or appeal any  taxes, or other charges described in clause (iii) above, but will not permit any such taxes or other charges to remain unpaid if such nonpayment will subject the Project (or portion of the Project) to loss or forfeiture.

Subject to the provisions of Section 3.4 hereof, the Company is not required by this Agreement to operate, or cause to be operated, the Project (or portion of the Project) owned by the Company after the Company deems in its discretion that such continued operation is not advisable, and in such event the Company may sell, lease or retire all or any such portion thereof.

Upon any such sale, lease or other disposition of the Project (or portion of the Project) in its entirety by the Company, the Company shall be discharged from its obligations to operate, maintain and insure the Project (or portion of the Project).  Any such sale, lease or other disposition shall comply with the requirements of each Tax Agreement.

The Issuer has no taxing power.
Neither the issuance of the Bonds nor the delivery of this Agreement shall, directly or indirectly or contingently, obligate the Issuer or the State or any political subdivision thereof to levy any form of taxation therefor or to make any appropriation for their payment.  Nothing in the Bonds or in the Indenture or this Agreement or the proceedings of the Issuer authorizing the Bonds or in the Act or in any other related document shall be construed to authorize the Issuer to create a debt of the Issuer or the State or any political subdivision thereof within the meaning of any constitutional or statutory provision of the State.

The Issuer has no taxing power.

the Issuer and its duly authorized agents shall have the right at all reasonable times during normal business hours to enter upon the site of the Project (or portion thereof) to examine and inspect the Project (or portion thereof); provided, however, that this right is subject to federal and State laws and regulations applicable to the site of the Project; and provided further that the Company reserves the right to restrict access to the Project (or portion thereof) in accordance with reasonably adopted procedures relating to safety and security.  The rights of access hereby reserved to the Issuer may be exercised only upon giving reasonable notice and after such agent shall have executed release of liability and secrecy agreements if requested by the Company in the form then currently used by the Company, and nothing contained in this Section or in any other provision of this Agreement shall be construed to entitle the Issuer to any information or inspection involving the confidential know-how of the Company.  The limitations contained in this Section do not affect any rights of inspection or other rights the Issuer has as a result of any law, ordinance, regulation, contract or other instrument.
Section 5.11.      Indenture Covenants.  The Company covenants to observe and perform all of the obligations imposed on it under the Indenture.

Section 6.2.      Remedies on Default.  Whenever any Event of Default referred to in Section 6.1 hereof shall have happened and be continuing, the Trustee, as assignee of the Issuer:
(a)    shall, by notice in writing to the Company and each Credit Provider, declare the unpaid balance of the Repayment Installments payable under Section 4.2(a) hereof to be due and payable immediately, if concurrently with or prior to such notice the unpaid principal amount of the Bonds shall have been declared to be due and payable, and upon any such declaration the same (being an amount sufficient, together with other moneys available therefor in the Bond Fund, to pay the unpaid principal of, premium, if any, and interest accrued on, the Bonds) shall become and shall be immediately due and payable as liquidated damages;
(b)    may take whatever action at law or in equity as may appear necessary or desirable to collect the payments and other amounts then due and thereafter to become due hereunder or to enforce performance and observance of any obligation, agreement or covenant of the Company under this Agreement; and
(c)    if applicable, shall draw upon any Credit Facility constituting a letter of credit or otherwise realize moneys under any Credit Facility as provided in the Indenture and such Credit Facility, if permitted by its terms and required by the terms of the Indenture, and apply the amount so drawn or realized in accordance with the Indenture and may exercise any remedy available to it thereunder.
Any amounts collected pursuant to action taken under this Section 6.2 shall be paid into the Bond Fund (unless otherwise provided in this Agreement) and applied in accordance with the provisions of the Indenture.  No action taken pursuant to this Section 6.2 shall relieve the Company from the Company’s obligations pursuant to Section 4.2 hereof.
No recourse shall be had for any claim based on this Agreement against any officer, director or stockholder, past, present or future, of the Company as such, either directly or through the Company, under any constitutional provision, statute or rule of law, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise.
Nothing herein contained shall be construed to prevent the Issuer from enforcing directly any of its rights under Sections 4.2(e), 4.2(g), 5.3 and 6.4 hereof.

-20-
4847-5363-8470.4 

The Company shall promptly notify the Issuer of any action taken by the Company under the grant of authority from the Issuer under Section 8.01 of the Indenture.
Section 6.3.      No Remedy Exclusive.  No remedy herein conferred upon or reserved to the Issuer or the Trustee is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement or now or hereafter existing at law or in equity or by statute.  No delay or omission to exercise any right or power accruing upon any default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right and power may be exercised from time to time and as often as may be deemed expedient.  In order to entitle the Issuer or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than such notice as may be herein expressly required.  Subject to the provisions of the Indenture and hereof, such rights and remedies as are given the Issuer hereunder shall also extend to the Trustee.  The Owners of the Bonds, subject to the provisions of the Indenture, shall be entitled to the benefit of all covenants and agreements herein contained.
Section 6.4.      Agreement to Pay Fees and Expenses of Counsel.  In the event the Company should default under any of the provisions of this Agreement and the Issuer or the Trustee should employ Counsel or incur other expenses for the collection of the indebtedness hereunder or the enforcement of performance or observance of any obligation or agreement on the part of the Company herein contained, the Company agrees that it will on written demand therefor pay to the Trustee or the Issuer (or to the Counsel for either of such parties if directed by such party), the reasonable fees and expenses of such Counsel and such other expenses so incurred by or on behalf of the Issuer or the Trustee.
Section 6.5.      No Additional Waiver Implied by One Waiver; Consents to Waivers.  In the event any agreement contained in this Agreement should be breached by either party and thereafter waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder.  No waiver shall be effective unless in writing and signed by the party making the waiver.  The Issuer shall have no power to waive any default hereunder by the Company without the consent of the Trustee to such waiver.  The Trustee shall have the power to waive any default by the Company hereunder, except a default under Section 3.4, 4.2(e), 4.2(g), 5.3 or 6.4 hereof, in so far as it pertains to the Issuer, without the prior written concurrence of the Issuer.  Notwithstanding the foregoing, if, after the acceleration of the maturity of the outstanding Bonds by the Trustee pursuant to Section 8.01 of the Indenture, (i) all arrears of principal of and interest on the outstanding Bonds and interest on overdue principal and (to the extent permitted by law) on overdue installments of interest at the rate of interest borne by the Bonds on the date on which such principal or interest became due and payable and the premium, if any, on all Bonds then Outstanding which have become due and payable otherwise than by 

-21-
4847-5363-8470.4 

acceleration, and all other sums payable under the Indenture, except the principal of and the interest on such Bonds which by such acceleration shall have become due and payable, shall have been paid, (ii) all other things shall have been performed in respect of which there was a default, (iii) there shall have been paid the reasonable fees and expenses of the Trustee and of the Owners of such Bonds, including reasonable attorneys’ fees paid or incurred and (iv) such event of default under the Indenture shall be waived in accordance with Section 8.04 of the Indenture with the consequence that such acceleration under Section 8.01 of the Indenture is rescinded, then the Company’s default hereunder shall be deemed to have been waived and its consequences rescinded and no further action or consent by the Trustee or the Issuer shall be required; provided that there has been furnished to the Trustee and the Issuer an Opinion of Bond Counsel to the effect that such waiver will not adversely affect the exemption from federal income taxes of interest on the Bonds.
Section 6.6.      Rights of Credit Providers upon an Event of Default.  Notwithstanding any other provision of this Article VI, while any Credit Facility is in effect for any series of Bonds and so long as such Credit Provider has not wrongfully dishonored a demand for payment made in strict compliance with the terms of the related Credit Facility for which payment remains unpaid by the Credit Provider, the Trustee and the Issuer may not exercise any remedy described in Section 6.2 hereof without each such Credit Provider’s prior written consent and no Event of Default hereunder shall be waived by the Trustee or the Issuer or the Bondholders to the extent they may otherwise be permitted to waive an Event of Default hereunder, without, in any case, the prior written consent of each such Credit Provider and, if applicable, rescission by each such Credit Provider of any notice of an event of default under the related Credit Agreement.  No Event of Default can be waived, in any circumstance, unless the Trustee has received written notice from each applicable Credit Provider that its Credit Facility has been fully reinstated and is in full force and effect.  While any Credit Facility is in effect for any series of Bonds and so long as such Credit Provider is not in default with respect to its obligations thereunder, such Credit Provider shall be entitled, but not obligated, to request that the Trustee exercise or to direct the Trustee in the exercise of all rights and remedies upon the occurrence of an Event of Default under the Indenture as provided in Section 8.11 thereof.
If a Credit Facility is in effect for any series of Bonds, and the Credit Provider wrongfully dishonors a demand for payment made in strict compliance with the terms of the related Credit Facility, for so long as such demand for payment remains unpaid by the Credit Provider, fifty-one percent (51%) of the Bondholders of the series of Bonds enhanced by such Credit Facility shall have the right at any time, by an instrument or instruments in writing executed and delivered to the Trustee, to direct the method and place of conducting all proceedings to be taken in connection with the enforcement of the terms and conditions of the Credit Facility or any other proceedings hereunder; provided that such direction shall be in accordance with applicable law.

EXHIBIT 4.3
NEVADA POWER COMPANY 
 
OFFICER’S CERTIFICATE
May 23, 2017
I, the undersigned officer of Nevada Power Company (the “Company”), do hereby certify that I am an Authorized Officer of the Company as such term is defined in the G&R Indenture (as defined herein). I am delivering this certificate pursuant to the authority granted in the Board Resolutions of the Company dated May 22, 2017, and Sections 1.04, 2.01, 3.01, 4.01(a) and 4.03(b)(i) of the General and Refunding Mortgage Indenture dated as of May 1, 2001, as heretofore amended and supplemented to the date hereof (as heretofore amended and supplemented, the “G&R Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (successor as trustee to The Bank of New York Mellon, formerly The Bank of New York), as Trustee (the “G&R Trustee”). Terms used herein and not otherwise defined herein shall have the meanings assigned to them in the G&R Indenture, unless the context clearly requires otherwise. Based upon the foregoing, I hereby certify on behalf of the Company as follows:
1.The terms and conditions of the Securities of the series established in this Officer’s Certificate to be issued under the G&R Indenture are as follows (the lettered subdivisions set forth in this Section 1 corresponding to the lettered subdivisions of Section 3.01 of the G&R Indenture):
(a)    The Securities of such series shall be designated “General and Refunding Mortgage Notes, Series AA” (the “Series AA Notes”).
(b)    There shall be no limit upon the aggregate principal amount of the Series AA Notes that may be authenticated and delivered under the G&R Indenture. Initially, two Tranches of Series AA Notes shall be authenticated and delivered, each Tranche evidenced by a single Series AA Note, in the following aggregate principal amounts: No. AA-1 $39,500,000 and No. AA-2 $53,000,000.
(c)    Not applicable.
(d)    The principal amount of each Tranche of Series AA Notes shall be payable by the Company in whole or in installments on such date or dates as follows:
(i)    for the Series AA Note, No. AA-1, in accordance with the Company’s principal repayment obligations under Section 4.2(a) of the Financing Agreement dated as of May 1, 2017 (the “Clark County Financing Agreement”) between the Company and Clark County, Nevada in respect of Clark County, Nevada’s Pollution Control Refunding Revenue Bonds (Nevada Power Company Project) Series 2017 (the “Clark County Bonds”) issued under the Indenture of Trust dated as of May 1, 2017 (the “Clark County Indenture”) between Clark County, Nevada and U.S. Bank National Association, as trustee (the “Clark County Trustee”); and

120179-0003/135316791.3 

(ii)    for the Series AA Note, No. AA-2, in accordance with the Company’s principal repayment obligations under Section 4.2(a) of the Financing Agreement dated as of May 1, 2017 (the “Coconino Financing Agreement”) between the Company and the Coconino County, Arizona Pollution Control Corporation in respect of the Coconino County, Arizona Pollution Control Corporation’s Pollution Control Refunding Revenue Bonds (Nevada Power Company Project) Series 2017A and Pollution Control Refunding Revenue Bonds (Nevada Power Company Project) Series 2017B (collectively, the “Coconino Bonds”) issued under the Indenture of Trust dated as of May 1, 2017 (the “Coconino Indenture”) between the Coconino County, Arizona Pollution Control Corporation and U.S. Bank National Association, as trustee (the “Coconino Trustee”).
The Clark County Financing Agreement and the Coconino Financing Agreement are hereinafter referred to collectively as the “Financing Agreements”, and individually, a “Financing Agreement”. The Clark County Bonds and the Coconino Bonds are hereinafter referred to collectively as the “Bonds”. The Clark County Indenture and the Coconino Indenture are hereinafter referred to collectively as the “Bond Indentures”, and individually, a “Bond Indenture”. The Clark County Trustee and the Coconino Trustee are hereinafter referred to collectively as the “Bond Trustees”, and individually, a “Bond Trustee”).
The obligation of the Company to make any payment of the principal on any Series AA Note shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has made a payment (or otherwise funded a payment) as provided in the related Financing Agreement, in respect of the principal of the related Bonds. If the Company shall fail to make any such payments in respect of principal on the Bonds of any issue or series, it shall be deemed to be a default, for the purposes of Section 10.01(b) of the G&R Indenture, in the payment of an amount of principal of the related Series AA Note equal to the amount of such unpaid principal in respect of such Bonds (but, in no event, shall such principal amount payable exceed the aggregate principal amount of such Series AA Note).
(e)    Each Tranche of Series AA Notes shall bear interest at such rate per annum as shall cause the amount of interest on each such Series AA Note to be equal to the amount in respect of interest payable by the Company in respect of the related Bonds (as specified within each Series AA Note). Interest on each Tranche of the Series AA Notes as set forth in the respective Bonds shall be payable on the same date or dates as payment in respect of such interest is payable by the Company from time to time in respect of the related Bonds.
The amounts payable by the Company from time to time in respect of interest on the Bonds, the basis on which such amounts are computed and the dates on which such amounts are payable are set forth in the respective Financing Agreements and the respective Bond Indentures. The obligation of the Company to make any payment of interest on any Series AA Note shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has made payments (or otherwise funded payments) in respect of interest on the related Bonds. If the Company 

120179-0003/135316791.3 

shall fail to make any such payments in respect of interest on any of the Bonds, it shall be deemed to be a default, for purposes of Section 10.01(a) of the G&R Indenture, in the payment of an amount of interest on the related Series AA Note equal to the amount of such unpaid amounts in respect of such Bonds.
The amount of interest that shall be payable upon the acceleration of the Stated Maturity of a Series AA Note pursuant to Section 10.02 of the G&R Indenture shall be the amount of accrued and unpaid interest on the related Bonds.
(f)    The corporate trust agency office of The Bank of New York Mellon Trust Company, N.A. at 101 Barclay Street in New York, New York 10286 shall be the place at which (i) the principal of and interest on the Series AA Notes shall be payable, (ii) registration of transfer of the Series AA Notes may be effected and (iii) exchanges of the Series AA Notes may be effected.

(g)    Not applicable.
(h)    Unless otherwise specified in a Series AA Note, the Company agrees that upon the occurrence and continuation of an Event of Default under Section 9.01(c) of the applicable Bond Indenture, the related Bond Trustee may demand an immediate mandatory redemption (in accordance with the applicable provisions under the applicable Bond Indenture) of the related Series AA Note in a principal amount equal to the unpaid purchase price obligation on such Bond, which unpaid amount resulted in such Event of Default under the applicable Bond Indenture. The Redemption Price on a Series AA Note in the event of such a mandatory redemption shall be equal to the principal amount thereof being redeemed plus accrued but unpaid interest to the Redemption Date.
(i)    The Series AA Notes are issuable in the same denominations as the Bonds; provided, however, that each of the Bonds will be secured by a single Series AA Note.
(j)    Not applicable.
(k)    Not applicable.

120179-0003/135316791.3 

(l)    Not applicable.
(m)    See subsections (d), (e) and (h) above.
(n)    Not applicable.
(o)    Not applicable.
(p)    Not applicable.
(q)    Each of the Series AA Notes shall be evidenced by a registered Series AA Note. The Series AA Notes may be executed by the Company and delivered to the G&R Trustee for authentication and delivery.
The initial Series AA Note of the initial Tranche of the Series AA Notes shall be identified by the number AA-1 and additional Series AA Notes shall be numbered consecutively from AA-2 upwards. The Series AA Notes shall upon issuance be delivered by the Company to, and registered in the name of, the applicable Bond Trustee, and shall be transferable only as required to effect an assignment thereof to a successor-in-interest of the applicable Bond Trustee under the respective Bond Indenture. The Series AA Notes are to be delivered to the applicable Bond Trustee as security for the payment by the Company of its obligations with respect to the applicable Bonds. Each Series AA Note shall be held by the applicable Bond Trustee subject to the terms of a Delivery Agreement between the Company and the applicable Bond Trustee.
Series AA Notes issued upon transfer or exchange shall be numbered consecutively from AA-3 upwards and issued in the same denominations as the Bonds but, to the extent that the aggregate outstanding principal amount of the Bonds shall have theretofore been reduced, the registered holder thereof shall duly note on the applicable Series AA Note a like reduction in such amount and shall notify the Company and the G&R Trustee of the name and address of the transferee and shall afford the Company and the G&R Trustee the opportunity of verifying the notation as to such reductions.
See also subsection (s) below.
(r)    Not applicable.
(s)    The holder of each Series AA Note by acceptance of the Series AA Note agrees to restrictions on transfer and to waivers of certain rights of exchange as set forth herein. In addition, the Series AA Notes will not be registered under the Securities Act of 1933 and the Series AA Notes may not be transferred without compliance with applicable securities laws. The Series AA Notes are not transferable except to a successor to the applicable Bond Trustee under the respective Bond Indenture.
(t)    For purposes of the Series AA Notes, “Business Day” shall have the meaning set forth in the applicable Bond Indenture.

120179-0003/135316791.3

1.    Principal.  The principal of this Note shall be payable by the Company in whole or in installments on such date or dates as the Company has any principal repayment obligations under Section 4.2(a) of the Financing Agreement dated as of May 1, 2017 (the “ ______ Financing Agreement”) between the Company and the Issuer in respect of the Issuer’s [bonds to be designated]

(collectively, the “ ______ Bonds”), or in whole on the Stated Maturity specified above (if not previously paid or deemed paid).
The obligation of the Company to make any payment of principal on this Note shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied or discharged to the extent that the Company has made a payment (or otherwise funded a payment) as provided in the  ______ Financing Agreement in respect of the principal of the  ______ Bonds. If the Company shall fail to make any such payments in respect of principal on the  ______ Bonds, it shall be deemed to be a default, for purposes of Section 10.01(b) of the G&R Indenture, in the payment of an amount of principal of this Note equal to the amount of such unpaid principal in respect of the  ______ Bonds (but, in no event, shall such principal amount payable exceed the aggregate principal amount of this Note).
2.    Interest.  This Note shall bear interest at such rate per annum as shall cause the amount of interest on this Note to be equal to the amount in respect of interest payable by the Company in respect of the  ______ Bonds. The interest on this Note shall be payable on the same date or dates as payment in respect of such interest is payable by the Company from time to time in respect of the  ______ Bonds.
The amounts payable by the Company in respect of interest on the  ______ Bonds, the basis on which such amounts are computed and the dates on which such amounts are payable are set forth in the  ______ Financing Agreement and the  ______ Indenture.

If the Company shall fail to make any such payments in respect of interest on the  ______ Bonds, it shall be deemed to be a default, for purposes of Section 10.01(a) of the G&R Indenture, in the payment of an amount of interest on this Note equal to the amount of such unpaid amounts in respect of the  ______ Bonds.
The amount of interest that shall be payable upon the acceleration of the Stated Maturity of this Note pursuant to Section 10.02 of the G&R Indenture shall be the amount of accrued and unpaid interest on the  ______ Bonds.

to or upon the Company may be served; and The Bank of New York Mellon Trust Company, N.A. shall be the Security Registrar for this Note; provided, however, that the Company reserves the right to change, by one or more Officer’s Certificates, with the consent of the  ______ Trustee, any such place or the Security Registrar; and provided, further, that the Company reserves the right to designate, by one or more Officer’s Certificates, its principal office in Las Vegas, Nevada as any such place or itself or any of its Subsidiaries as the Security Registrar; provided, however, that there shall be only a single Security Registrar for this Note. The principal of this Note shall be payable without the presentment or surrender thereof.
5.    G&R Indenture; Security. This Note is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or more series under and equally secured by a General and Refunding Mortgage Indenture, dated as of May 1, 2001 (such G&R Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the “G&R Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (successor as trustee to The Bank of New York Mellon, formerly The Bank of New York), as trustee (herein called the “G&R Trustee,” which term includes any successor trustee under the G&R Indenture), to which G&R Indenture and all indentures supplemental thereto reference is hereby made for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the G&R Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities are, and are to be, authenticated and delivered and secured. The acceptance of this Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the G&R Indenture. This Note is one of the series designated above.
6.    Sinking Fund; Optional Redemption.  This Note will not be entitled to the benefit of any sinking fund or optional redemption provisions.
7.    Event of Default.  If an Event of Default, as defined in the G&R Indenture, shall occur and be continuing, the principal of this Note may be declared due and payable in the manner and with the effect provided in the G&R Indenture and herein.
8.    Mandatory Redemption. Upon the occurrence and continuation of an Event of Default under Section 8.01(c) of the  ______ Indenture, the  ______ Trustee may demand an immediate mandatory redemption (in accordance with the applicable provisions under the  ______ Indenture) of this Note in a principal amount equal to the unpaid purchase price obligation on the  ______ Bonds, which unpaid amount resulted in such Event of Default under the  ______ Indenture. The Redemption Price on this Note in the event of such a mandatory redemption shall be equal to the principal amount thereof being redeemed plus accrued but unpaid interest to the Redemption Date.
9.    Supplemental G&R Indentures. The G&R Indenture permits, with certain exceptions as therein provided, the G&R Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the G&R Indenture with the consent of the Holders of not less than a majority in aggregate 

120179-0003/135316791.3 

principal amount of the Securities of all series then Outstanding under the G&R Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the G&R Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the G&R Indenture permits the G&R Trustee to enter into one or more supplemental indentures for limited purposes without the consent of any Holders of Securities.
10.    Consents and Waivers. The G&R Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the G&R Indenture and certain past defaults under the G&R 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 Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.
11.    Person Deemed Owners. The Company, the G&R Trustee and any agent of the Company or the G&R Trustee may deem and treat the person in whose name this Note shall be registered upon the Security Register for the Notes of this series as the absolute owner of such Note for the purpose of receiving payment of or on account of the principal of and interest on this Note and for all other purposes, whether or not this Note be overdue, and neither the Company nor the G&R Trustee shall be affected by any notice to the contrary; and all such payments so made to such registered owner or upon his order shall be valid and effectual to satisfy and discharge the liability upon this Note to the extent of the sum or sums paid.
12.    Satisfaction and Discharge. The G&R Trustee may conclusively presume that the obligation of the Company to pay the principal of and interest on this Note, when such payment is required to be made as provided herein, shall have been fully satisfied and discharged unless and until it shall have received a written notice from the  ______ Trustee, signed by an authorized officer of the  ______ Trustee, stating that the payment in respect of principal or interest, on the  ______ Bonds has not been fully paid or provided for when due under the terms of the  ______ Financing Agreement and specifying the amount of funds required to make such payment.
13.    Transfer. This Note is not transferable except to a successor to the  ______ Trustee under the  ______ Indenture. Before any transfer of this Note by the registered holder or his or its legal representative will be recognized or given effect by the Company or the G&R Trustee, the registered holder shall note the amounts of reductions, if any, in the aggregate outstanding principal amount of the  ______ Bonds, and shall notify the Company and the G&R Trustee of the name and 

120179-0003/135316791.3 

address of the transferee and shall afford the Company and the G&R Trustee the opportunity of verifying the notation as to such reductions.
14.    No Recourse. No recourse under or upon any obligation, covenant or agreement contained in the G&R Indenture or in any indenture supplemental thereto, or in any Note or coupon thereby secured, or because of any indebtedness thereby secured, shall be had against any incorporator, or against any past, present or future stockholder, officer or director, as such, of the Company or any successor corporation, either directly or through the Company or of any successor corporation under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise; it being expressly agreed and understood that the G&R Indenture, any indenture supplemental thereto and the obligations thereby secured, are solely corporate obligations, and that no personal liability whatsoever shall attach to, or be incurred by, such incorporators, stockholders, officers or directors, as such, of the Company or of any successor corporation, or any of them, because of the incurring of the indebtedness thereby authorized, or under or by reason of any of the obligations, covenants or agreements contained in the G&R Indenture or in any indenture supplemental thereto or in any of the Notes or coupons thereby secured, or implied therefrom.
15.    Business Day. For the purposes of this Note, “Business Day” shall have the meaning set forth in the  ______ Indenture.
16.    Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of New York.
17.    Certificate of Authentication. Unless the certificate of authentication hereon has been executed by the G&R Trustee or an Authenticating Agent by manual signature, this Note shall not be entitled to any benefit under the G&R Indenture or be valid or obligatory for any purpose.
