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, 3.070 Series due 2050, 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.

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. Each initial and subsequent holder of bonds of this series, by virtue of its acquisition of an interest therein, shall be deemed, without further act, to have consented to the prospective amendments to the Original Mortgage set forth or referred to in the Sixty-fourth Supplemental Indenture. 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.
