If the Maturity Date or an Interest Payment Date falls on a day which is not a Business Day, -5- as defined below, principal or interest payable with respect to such Maturity Date or Interest Payment Date will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity Date or Interest Payment Date, as the case may be.

Bonds of the 2012 Second Series are bonds of an authorized issue of bonds of the Company known as First Mortgage Bonds, not limited as to maximum aggregate principal amount, all issued or issuable in one or more series under and equally secured (except insofar as any sinking fund, replacement fund or other fund established in accordance with the provisions of the Indenture hereinafter mentioned may afford additional security for the bonds of any specific series) by an Indenture of Mortgage and Deed of Trust dated July 1, 1945, duly executed and delivered by the Company to HSBC Bank USA (formerly known as The Marine Midland Trust Company of New York), as Trustee, as supplemented, amended and modified by fifty supplemental indentures and by the Fifty-first Supplemental Indenture (such Indenture of Mortgage and Deed of Trust as so supplemented, amended and modified by such fifty supplemental indentures and the Fifty-first Supplemental Indenture being hereinafter called the "Indenture"), to which Indenture and all indentures supplemental thereto, including the Fifty-first Supplemental Indenture, reference is hereby made for a description of the property mortgaged and pledged as security for said bonds, the nature and extent of the security, and the rights, duties and immunities thereunder of the Trustee, the rights of the holders of said bonds and of the Trustee and of the Company in respect of such security, and the terms upon which said bonds may be issued thereunder. Capitalized terms used herein and not defined herein shall have the respective meanings in the Indenture, unless otherwise noted. The Bonds of the 2012 Second Series shall be redeemed in whole by the Company prior to maturity (a) upon the sale or disposition substantially as an entirety of the Company's electric properties at Portland, Oregon, at a price ("Redemption Price") equal to the greater of (i) 100% of the principal amount hereof and (ii) an amount equal to the present value of the remaining principal and interest payments due under this bond (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, together in either case with accrued and unpaid interest to the date of redemption, upon notice to the holders of the Bonds of the 2012 Second Series given not more than ninety (90) nor less than thirty (30) days prior to the date of such redemption; (b) upon the sale or other disposition substantially as an entirety, whether in one or more transactions, of the electric distribution and transmission assets and properties of the Company in its service territory at the Redemption Price, upon notice given not more than ninety (90) nor less than thirty (30) days prior to the date of such redemption; and (c) upon written notice to the Trustee and the Company from Ambac that the Company is in breach of its covenant in Section 3.01(a) of the Insurance Agreement by and between the Company and Ambac dated October 28, 2002, at the Redemption Price, upon notice given not more than ninety (90) nor less than thirty (30) days prior to the date of such redemption.

In the event of the selection for redemption of a portion only of the principal of this bond, payment of the Redemption Price will be made only upon surrender of this bond in exchange for a bond or bonds (but only of authorized denominations of the same series) for the unredeemed balance of the principal amount of this bond. The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than seventy-five percent in principal amount of the bonds (exclusive of bonds disqualified by reason of the Company's interest therein) at the time outstanding, including, if more than one series of bonds shall be at the time outstanding, not less than sixty percent in principal amount of each series affected, to effect, by an indenture supplemental to the Indenture, modifications or alterations of the Indenture and of the rights and obligations of the Company and of the holders of the bonds and coupons; provided, however, that no such modification or alteration shall be made without the written approval or consent of the holder hereof which will (i) extend the maturity of this bond or reduce the rate or extend the time of payment of interest hereon or reduce the amount of the principal hereof, (ii) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of the Indenture, or (iii) reduce the percentage of the principal amount of the bonds upon the approval or consent of the holders of which modifications or alterations may be made as aforesaid. The transfer of this bond is registrable by the registered owner hereof in person or by such owner's attorney duly authorized in writing, at the corporate trust office of the Trustee in the Borough of Manhattan, City and State of New York, upon surrender of this bond for cancellation and upon payment of any taxes or other governmental charges payable upon such transfer, and thereupon a new registered bond or bonds of the same series and of a like aggregate principal amount will be issued to the transferee or transferees in exchange therefor. The Company, the Trustee and any paying agent may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payments of or on account of the principal hereof and interest due hereon, and for all other purposes, whether or not this bond shall be overdue, and neither the Company, the Trustee nor any paying agent shall be affected by any notice to the contrary. Bonds of this series are issuable only in fully registered form without coupons in denominations of $250,000 or any amount in excess thereof that is an integral multiple thereof. The registered owner of this bond at its option may surrender the same for cancellation at said office of the Trustee and receive in exchange therefor the same aggregate principal amount of registered bonds of the same series but of other authorized denominations upon payment of any taxes or other governmental charges payable upon such exchange and subject to the terms and conditions set forth in the Indenture. If an event of default as defined in the Indenture shall occur, the principal of this bond may become or be declared due and payable before maturity in the manner and with the effect provided in the Indenture. The holders, however, of certain specified percentages of the bonds at -10- the time outstanding, including in certain cases specified percentages of bonds of particular series, may in certain cases, to the extent and as provided in the Indenture, waive certain defaults thereunder and the consequences of such defaults. No recourse shall be had for the payment of the principal of or the interest on this bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, against any incorporator, shareholder, director or officer, past, present or future, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company or such predecessor or successor corporation, under any constitution or statute or rule of law, or by the enforcement of any assessment or penalty, or otherwise, all such liability of incorporators, shareholders, directors and officers, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and as provided in the Indenture. The Indenture provides that this bond shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be construed in accordance with and governed by the laws of said State.

ARTICLE ONE. BONDS OF THE 2012 SECOND SERIES AND CERTAIN PROVISIONS RELATING THERETO. SECTION 1.01. Certain Terms of Bonds of the 2012 Second Series. (a) There is hereby established a series of First Mortgage Bonds of the Company designated and entitled as "First Mortgage Bonds, 5.6675% Series due 2012" (sometimes referred to as the "Bonds of the 2012 Second Series"). The aggregate principal amount of the Bonds of the 2012 Second Series shall be limited to $100,000,000, excluding, however, any Bonds of the 2012 Second Series which may be executed, authenticated and delivered in exchange for or in lieu of or in substitution for other Bonds of such Series pursuant to the provisions of the Indenture. (b) The definitive Bonds of the 2012 Second Series shall be issuable in substantially the form as hereinabove set forth in fully registered form without coupons in the denomination of $250,000, or any amount in excess thereof that is an integral multiple thereof. Notwithstanding -13- the provisions of Section 2.05 of the Mortgage, each Bond of the 2012 Second Series shall be dated as of the date of its authentication, shall mature on October 25, 2012 (the "Maturity Date"), except to the extent redeemed or repaid prior to the Maturity Date, and shall bear interest for the period ("Interest Period") from the October 15 or April 15 as the case may be, next preceding the date thereof to which interest has been paid, or, if the date thereof is an October 15 or April 15 to which interest has been paid, from the date thereof, or, if the date thereof is prior to April 15, 2003, from the date thereof, except that from April 15, 2012 the Interest Period shall extend to and the Interest Payment Date shall be the Maturity Date, provided, however, that if and to the extent the Company shall default in payment of the interest due on such October 15 or April 15, then from the next preceding date to which interest has been paid or if such default shall be in respect of the interest due on April 15, 2003, then from the date thereof. Each Bond of the 2012 Second Series shall bear interest at the rate of 5.6675% per annum (calculated on the basis of a 360-day year of twelve 30-day months) until the payment of the principal thereof has been made or duly provided for, such interest to be payable semi-annually on October 15 and April 15 ("Interest Payment Date") in each year. If the Maturity Date or an Interest Payment Date falls on a day which is not a Business Day, as defined below, principal or interest payable with respect to such Maturity Date or Interest Payment Date will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity Date or Interest Payment Date, as the case may be. The person in whose name any Bond of the 2012 Second Series is registered at the close of business on the applicable Record Date (as defined below) with respect to any Interest Payment Date shall be entitled to receive the interest payable thereon on such Interest Payment Date notwithstanding the cancellation of such Bond of the 2012 Second Series upon any registration of transfer or exchange thereof subsequent to such Record Date and prior to such Interest Payment Date, unless the Company shall default in the payment of the interest due on such Interest Payment Date, in which case such defaulted interest shall be paid to the person in whose name such Bond is registered on a subsequent record date fixed by the Company, which subsequent record date shall be fifteen (15) days prior to the payment of such defaulted interest; provided, however, that interest payable on the Maturity Date will be payable to the person to whom the principal hereof shall be payable. As used herein the term "Business Day" means any day, other than a Saturday or Sunday, that is not a legal holiday or other day on which banking institutions are required or authorized by law, regulation or executive order to close in The City of New York, New York, or London, England. As used herein, the term "Record Date" with respect to any Interest Payment Date shall mean the fifteenth day (whether or not such day is a Business Day) next preceding such Interest Payment Date. The principal of and interest on the Bonds of the 2012 Second Series shall be payable in any coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts at the office or agency of the Company in the Borough of Manhattan, City and State of New York, no later than 1:00 p.m. New York time. (c) Notwithstanding the above, from the date hereof, but only so long as the Financial Guaranty Insurance Policy No. 20049BE (the "Policy") issued by Ambac Assurance Corporation, or any successor thereto ("Ambac"), insuring the payments of the principal and interest on the Bonds of the 2012 Second Series shall be outstanding, the principal sum shall be paid, in advance, on the third Business Day immediately preceding the Maturity Date ("Advance Principal Payment Date"), and interest for each Interest Period shall be paid, in advance, on the -14- third Business Day immediately preceding the applicable Interest Payment Date ("Advance Interest Payment Date"). (d) Notwithstanding anything to the contrary in the Indenture, the Company will pay to the Trustee by 11:00 a.m., New York City time, on each Advance Principal Payment Date or Advance Interest Payment Date immediately available funds in an amount sufficient to pay all principal and interest due on the Bonds of the 2012 Second Series due on such Advance Principal Payment Date or Advance Interest Payment Date. At or prior to 1:00 p.m., New York City time, on each Advance Principal Payment Date or Advance Interest Payment Date, the Trustee shall determine whether there has been deposited by the Company with the Trustee sufficient funds to pay the principal of or interest on the Bonds of the 2012 Second Series on such Advance Principal Payment Date or Advance Interest Payment Date. If the Trustee determines that it has received from the Company insufficient funds to make such payment, the Trustee shall so notify Ambac in writing in the manner required by Section 3.03 hereof. Such notice shall specify the amount of the anticipated deficiency and whether the payment to be made on the Bonds of the 2012 Second Series on such Advance Principal Payment Date or Advance Interest Payment Date will be deficient as to principal or interest, or both. (e) The Trustee shall, after giving notice to Ambac as provided in Section 1.01(d) above, make available to Ambac and, at Ambac's direction, to The Bank of New York, in New York, New York, as insurance trustee for Ambac or any successor insurance trustee (the "Insurance Trustee"), the registration books of the Company maintained by the Trustee with respect to the Bonds of the 2012 Second Series, and all payment records of the Trustee in respect of the Bonds of the 2012 Second Series maintained under this Supplemental Indenture. (f) In the event the Trustee notifies Ambac of any deficiency of interest or principal payable on the Bonds of the 2012 Second Series pursuant to Section 1.01(d) above, the Trustee shall provide Ambac and, at Ambac's direction, the Insurance Trustee with a list of holders of Bonds of the 2012 Second Series entitled to receive principal or interest payments from Ambac under the terms of the Policy, and shall make arrangements with the Insurance Trustee (i) to mail checks or drafts to the holders of Bonds of the 2012 Second Series entitled to receive full or partial interest payments from Ambac and (ii) to pay principal upon Bonds of the 2012 Second Series surrendered to the Insurance Trustee by the holders of Bonds of the 2012 Second Series entitled to receive full or partial principal payments from Ambac. (g) The Trustee shall, within one Business Day of the time it provides notice to Ambac pursuant to Section 1.01(d) above, furnish a notice substantially in the form of Annex A hereto, to the holders of Bonds of the 2012 Second Series entitled to receive the payment of principal or interest thereon from Ambac (i) as to the fact of such entitlement, (ii) that Ambac will remit to them all or a part of the interest payments next coming due upon proof of the holders' entitlement to interest payments and delivery to the Insurance Trustee of an appropriate assignment (the form of which shall be provided by Ambac) of the holders' right to such payment, (iii) that should they be entitled to receive full payment of principal from Ambac, they must surrender their Bonds of the 2012 Second Series (along with an appropriate instrument of assignment (the form of which shall be provided by Ambac) to permit ownership of such Bonds of the 2012 Second Series to be registered in the name of Ambac) for payment to the Insurance Trustee, and not the Trustee, and (iv) that -15- should they be entitled to receive partial payment of principal from Ambac, they must surrender their Bonds of the 2012 Second Series for payment thereon first to the Trustee, which shall note on such Bonds of the 2012 Second Series the portion of the principal paid by the Trustee or any paying agent, and then, along with an appropriate instrument of assignment (the form of which shall be provided by Ambac), to the Insurance Trustee, which will then pay the unpaid portion of principal. (h) In the event the Trustee has received written notice that any payment of principal of or interest on Bonds of the 2012 Second Series that has become due and payable and has been made to a holder of the Bonds of the 2012 Second Series by or on behalf of the Company has been deemed a preferential transfer and theretofore recovered from such holder or former holder of such Bond of the 2012 Second Series pursuant to the United States Bankruptcy Code by a trustee in bankruptcy in accordance with the final, nonappealable order of a court having competent jurisdiction, the Trustee shall, at the time Ambac is notified pursuant to Section 1.01(d) above, notify all holders of Bonds of the 2012 Second Series that in the event that any holder's payment is so recovered, such holder will be entitled to payment from Ambac to the extent of such recovery if sufficient funds are not otherwise available, and the Trustee shall furnish to Ambac its records evidencing the payments of principal of and interest on the Bonds of the 2012 Second Series that have been made by the Trustee and subsequently recovered from holders and the dates on which such payments were made. (i) In addition to those rights granted Ambac under this Supplemental Indenture, Ambac shall, to the extent it makes payment of principal of or interest on Bonds of the 2012 Second Series, become subrogated to the rights of the recipients of such payments in accordance with the terms of the Policy, and to evidence such subrogation (i) in the case of subrogation as to claims for past due interest, the Trustee shall note Ambac's rights as subrogee on the registration books of the Company maintained by the Trustee upon receipt from Ambac of proof of the payment of interest thereon to the holders of the Bonds of the 2012 Second Series, and (ii) in the case of subrogation as to claims for past due principal, the Trustee shall note Ambac's rights as subrogee on the registration books of the Company maintained by the Trustee upon surrender of the Bonds of the 2012 Second Series by the holders thereof. (j) Upon compliance with the provisions of Section 2.06 of the Mortgage and as provided in this Supplemental Indenture, and upon payment of any taxes or other governmental charges payable upon such exchange, Bonds of the 2012 Second Series may be exchanged for a new Bond or Bonds of the 2012 Second Series of different authorized denominations of like aggregate principal amount. The Trustee hereunder shall, by virtue of its office as such Trustee, be the registrar and transfer agent of the Company for the purpose of registering permitted transfers of Bonds of the 2012 Second Series. (k) Notwithstanding the provisions of Section 2.11 of the Mortgage, no service charge shall be made for any exchange or registration of transfer of Bonds of the 2012 Second Series, but the Company at its option may require payment of a sum sufficient to cover any tax or other governmental charge incident thereto. -16- SECTION 1.02. Mandatory Redemption of Bonds of the 2012 Second Series. (a) The Bonds of the 2012 Second Series shall be redeemed prior to maturity, as a whole: (i) Upon the sale or disposition substantially as an entirety of the Company's electric properties at Portland, Oregon, at a price ("Redemption Price") equal to the greater of (i) 100% of the principal amount thereof and (ii) an amount equal to the present value of the remaining principal and interest payments due under the Bonds of the 2012 Second Series (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, together in either case with accrued and unpaid interest to the date of redemption. The Company shall give Ambac and the Trustee written notice of the Redemption Price ("Price Notice") immediately after the calculation thereof, and the Trustee shall have no responsibility for such calculation. (ii) Upon the sale or disposition substantially as an entirety, whether in one or more transactions, of the electric distribution and transmission assets and properties of the Company in its service territory, at the Redemption Price.

The Company shall provide the Price Notice to Ambac and the Trustee immediately after the calculation of the Redemption Price, and the Trustee shall have no responsibility for such calculation. (b) Redemption pursuant to this Section 1.02 shall take place upon prior notice given by mailing such notice to the respective registered owners of such Bonds of the 2012 Second Series not less than thirty (30) nor more than ninety (90) days prior to the date of redemption and as otherwise required by the provisions of Article Nine of the Mortgage.
