WHEREAS in addition to the property described in the Mortgage the Company has acquired certain other property, rights and interests in property; and
WHEREAS Section 120 of the Original Mortgage, as heretofore amended, provides that, without the consent of any holders of bonds, the Company and the Trustee, at any time and from time to time, may enter into indentures supplemental to the Original Mortgage for various purposes set forth therein, including, without limitation, to cure ambiguities or correct defective or inconsistent provisions or to make other changes therein that shall not adversely affect the interests of the holders of bonds of any series in any material respect or to establish the form or terms of bonds of any series as contemplated by Article II; and
WHEREAS the Company now desires to create a new series of bonds; and
WHEREAS Section 8 of the Original Mortgage, as heretofore amended, provides that the form of each series of bonds (other than the First Series) issued thereunder and of the coupons to be attached to coupon bonds of such series shall be established by Resolution of the Board of Directors of the Company or by Treasurer’s Certificate, or shall be set forth in an indenture supplemental to the Original Mortgage; that the form of such series, as so established, shall specify the descriptive title of the bonds and various other terms thereof; and that such series may also contain such provisions not inconsistent with the provisions of the Mortgage as the Company may, in its discretion, cause to be inserted therein expressing or referring to the terms and conditions upon which such bonds are to be issued and/or secured under the Mortgage; and

D-1








The principal of and premium, if any, and interest on this bond payable at Maturity shall be payable upon presentation hereof at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.  The interest on this bond (other than interest payable at Maturity) shall be paid directly to the registered owner hereof.  As used herein, the term “Maturity” shall mean the date on which the principal of this bond becomes due and payable, whether at stated maturity, upon redemption or acceleration, or otherwise.
This bond is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage Bonds, Collateral Series 2020A, all bonds of all such series being issued and issuable under and equally secured (except insofar as any sinking or other fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust, dated as of June 1, 1939 (the “Original Mortgage”), executed by the Company (formerly known as The Washington Water Power Company) to City Bank Farmers Trust Company and Ralph E. Morton, as Trustees (Citibank, N.A., successor Trustee to both said Trustees).  The Original Mortgage has been amended and supplemented by various supplemental indentures, including the Sixty-third Supplemental Indenture, dated as of June 1, 2020 (the “Sixty-third Supplemental Indenture”), and, as so amended and supplemented, is herein called the “Mortgage.”  Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee, the terms and conditions upon which the bonds are and are to be secured and the circumstances under which additional bonds may be issued.  If there shall be a conflict between the terms of this bond and the provisions of the Mortgage, the provisions of the Mortgage shall control to the extent permitted by law.  The holder of this bond, by its acceptance hereof, shall be deemed to have consented and agreed to all of the terms and provisions of the Mortgage.
The Mortgage may be modified or altered by affirmative vote of the holders of at least 60% in principal amount of the bonds outstanding under the Mortgage, considered as one class, or, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected, then such modification or alteration may be effected with the affirmative vote only of 60% in principal amount of the bonds outstanding of the series so to be affected, considered as one class, and, furthermore, for limited purposes, the Mortgage may be modified or altered without any consent or other action of holders of any series of bonds.  No modification or alteration shall, however, permit an extension of the Maturity of the principal of, or interest on, this bond or a reduction in such principal or the rate of interest hereon or any other modification in the terms of payment of such principal or interest or the creation of any lien equal or prior to the lien of the Mortgage or deprive the holder of a lien on the mortgaged and pledged property without the consent of the holder hereof.
The bonds of this series are not redeemable, in whole or in part, at the option of the Company.
The bonds of this series have been issued and delivered to MUFG Union Bank, N.A. (formerly known as Union Bank, N.A.), as Administrative Agent under the Credit Agreement (as such terms are defined in the Sixty-third Supplemental Indenture) in order to provide the benefit 


D-2







of the lien of the Mortgage as security for the obligation of the Company under the Credit Agreement to pay the Obligations (as so defined), to the extent and subject to the limitations set forth below.  Subject to the terms and conditions specified in the Sixty-third Supplemental Indenture, the Stated Maturity Date shall be automatically extended upon the extension of the Expiration Date (as such term is defined in the Sixty-third Supplemental Indenture) pursuant to any provision of the Credit Agreement, but in no event beyond December 31, 2050.
Upon the earliest of (A) the occurrence of an Event of Default (as defined in the Sixty-third Supplemental Indenture) under the Credit Agreement, other than an Event of Default referred to in clause (B) below, and further upon the condition that, in accordance with the terms of the Credit Agreement, (1) the Commitments (as so defined) shall have been or shall have terminated and any Loans (as so defined) shall have been declared to be or shall have otherwise become due and payable immediately, (2) the Administrative Agent shall have demanded that the Company provide cash collateral in the amount of the total LC Exposure (as so defined), if any, and (3) the Administrative Agent shall have delivered to the Company a notice demanding redemption of the bonds of this series which notice states that it is being delivered pursuant to Article VII of the Credit Agreement, (B) the occurrence of an Event of Default under paragraph (g) or (h) of Article VII of the Credit Agreement, and (C) the Stated Maturity Date, then all bonds of this series shall be redeemed or paid immediately at the principal amount thereof plus accrued interest to the date of redemption or payment.
The obligation of the Company to pay the accrued interest on bonds of this series on any Interest Payment Date prior to Maturity (a) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Obligations shall have been paid or (b) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of interest on the bonds of this series).
The obligation of the Company to pay the principal of and accrued interest on bonds of this series at or after Maturity (x) shall be deemed to have been satisfied and discharged in full in the event that (1) all amounts then due in respect of the Obligations shall have been paid and (2) no Letter of Credit (as defined in the Sixty-third Supplemental Indenture) shall remain outstanding (or all outstanding Letters of Credit shall have been cash collateralized in full pursuant to the terms of the Credit Agreement) or (y) shall be deemed to remain unsatisfied in an amount equal to the sum of (1) the aggregate amount then due in respect of the Obligations and remaining unpaid plus (2) the aggregate stated amount of all outstanding Letters of Credit to the extent that such Letters of Credit have not been cash collateralized pursuant to the terms of the Credit Agreement (not in excess, however, of the amount otherwise then due in respect of principal of and accrued interest on the bonds of this series).
Anything in this bond to the contrary notwithstanding, if, at the time of the Maturity of the bonds of this series, the stated aggregate principal amount of such bonds then outstanding shall exceed the aggregate amount of the Commitments (provided that the aggregate amount of the Commitments shall be determined without regard to any termination of the Commitments at such time or pursuant to Section 2.10(a) or Article VII of the Credit Agreement), the aggregate principal amount of such bonds shall be deemed to have been reduced by the amount of such excess.


D-3







The principal hereof, together with all accrued and unpaid interest hereon, may be declared or may become due prior to the Stated Maturity Date on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a Completed Default as in the Mortgage provided.
As provided in the Mortgage and subject to certain limitations therein set forth, this bond or any portion of the principal amount hereof will be deemed to have been paid if there has been irrevocably deposited with the Trustee moneys or direct obligations of or obligations guaranteed by the United States of America, the principal of and interest on which when due, and without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient to pay when due the principal of and premium, if any, and interest on this bond when due.
The Mortgage contains terms, provisions and conditions relating to the consolidation or merger of the Company with or into, and the conveyance or other transfer, or lease, of assets to, another corporation and to the assumption by such other corporation, in certain circumstances, of all of the obligations of the Company under the Mortgage and on the bonds secured thereby.
This bond is non-transferable except as required to effect transfer to any successor administrative agent under the Credit Agreement, any such transfer to be made at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, together with a written instrument of transfer whenever required by the Company duly executed by the registered owner or by its duly authorized attorney, and, thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage.  The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes.
In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.
No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.
This bond shall not become obligatory until Citibank, N.A., the Trustee under the Mortgage, or its successor thereunder, shall have signed the form of certificate endorsed hereon.
