This bond will not be subject to any sinking fund. This bond may be subject to repayment at the option of the holder on the Optional Repayment Date(s), if any, indicated on the face hereof. If no Optional Repayment Dates are set forth on the face hereof, this bond may not be so repaid at the option of the holder hereof prior to maturity. On any Optional Repayment Date this bond shall be repayable in whole or in part in increments of $1,000 (provided that any remaining principal hereof shall be at least $100,000) at the option of the holder hereof at a repayment price equal to 100% of the principal amount to be repaid, together with interest thereon payable to the date of repayment. For this bond to be repaid in whole or in part at the option of the holder hereof, this bond must be received, with the form entitled "Option to Elect Repayment" below duly completed, by the Trustee at 140 Broadway, New York, New York 10005-1180, or such address which the Company shall from time to time notify the holders of the bonds, not more than 60 nor less than 20 days prior to an Optional Repayment Date. Exercise of such repayment option by the holder hereof shall be irrevocable. This bond may be redeemed by the Company on any date on and after the Initial Regular Redemption Date, if any, indicated on the face hereof. If no Initial Regular Redemption Date is set forth on the face hereof, this 39 9 bond may not be redeemed prior to maturity, except as provided in the second succeeding paragraph. On and after the Initial Regu- lar Redemption Date, if any, this bond may be redeemed at any time in whole or from time to time in part in increments of $1,000 (provided that any remaining principal hereof shall be at least $100,000) at the option of the Company at the applicable Regular Redemption Price (as defined below) together with interest thereon payable to the date of such redemption, on notice given not more than 90 nor less than 30 days prior to such date. Any date on which Bonds are to be redeemed is herein called a "Redemption Date". The "Regular Redemption Price" shall initially be the Initial Regular Redemption Percentage, shown on the face hereof, of the principal amount of this bond to be redeemed and shall decline at each anniversary of the Initial Regular Redemption Date, shown on the face hereof, by the Annual Regular Redemption Percentage Reduction, if any, shown on the face hereof, of the principal amount to be redeemed until the Regular Redemption Price is 100% of such principal amount. The Bonds may be redeemed prior to maturity as a whole at any time or in part from time to time (in increments as specified in the second preceding paragraph) in the instances provided in the Indenture by the application of proceeds of the sale or disposition substantially as an entirety of the Company's electric properties at Portland, Oregon, upon payment of the principal amount thereof, together with interest accrued to the date of such redemption, on notice given as provided in such second preceding paragraph. Interest payments on this bond will include interest accrued to but excluding the Interest Payment Date or the Maturity Date, as the case may be.

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 an 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 $100,000 or integral multiples of $1,000 in excess thereof. The registered owner of this bond at his 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 and with the same terms and provisions, including the same issue date, maturity date, and redemption provisions, if any, and which bear interest at the same rate, but of other authorized denominations, upon payment of any taxes or other governmental charges payable upon 41 11 such exchange and subject to the terms and conditions set forth in the Indenture.

Interest on Bonds of the Medium Term Note Series III shall be payable on the dates edstablished on the date of first authentication of such Bond ("Original Issue Date"). The person in whose name any Bond of the Medium Term Note Series III is registered at the close of business on the applicable record date 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 upon any 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. Such interest payments shall be made in such manner and in such places as provided on the Form of Bonds of the Medium Term Note Series III set forth in this Supplemental Indenture. The principal of the Bonds of the Medium Term Note Series III shall be payable in any coin or currency 46 16 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, and interest and premium, if any, on such Bonds shall be payable in like coin or currency at said office or agency. The definitive Bonds of the Medium Term Note Series III may be issued in the form of Bonds, engraved, printed or lithographed on steel engraved borders. Upon compliance with the provisions of Section 2.06 of the Original Indenture and as provided in this Supplemental Indenture, and upon payment of any taxes or other governmental charges payable upon such exchange, Bonds of the Medium Term Note Series III may be exchanged for a new Bond or Bonds 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 and transferring Bonds of the Medium Term Note Series III. Notwithstanding the provisions of Section 2.11 of the Original Indenture, no service charge shall be made for any exchange or transfer of Bonds of the Medium Term Note Series III, but the Company at its option may require payment of a sum sufficient to cover any tax or other governmental charge incident thereto. SECTION 1.02. Redemption Provisions for Bonds of the Medium Term Note Series III. The Bonds of the Medium Term Note Series III shall be subject to redemption prior to maturity as a whole at any time or in part from time to time as the Board of Directors of the Company, or any officer of the Company acting pursuant to authority granted by the Board of Directors may determine, and as set forth on the Form of Bonds of the Medium Term Note Series III set forth in this Supplemental Indenture. The Bonds of the Medium Term Note Series III which are redeemable on the payment of a Regular Redemption Price as provided for in this Section 1.02 may be redeemed at such Regular Redemption Price through the application of cash deposited with the Trustee pursuant to Section 6.04 of the Original Indenture upon the taking, purchase or sale of any property subject to the lien hereof or thereof in the manner set forth in said Section.

SECTION 1.03. Notwithstanding the provisions of Section 4.07 of the Original Indenture, the provisions of Sections 4.04, 4.05, and 4.06 of the Original Indenture shall remain in full force and effect and shall be performed by the Company so long as any Bonds of the Medium Term Note Series III remain outstanding. The Bonds of the Medium Term Note Series III which are redeemable on the payment of a Regular Redemption Price as provided for in Section 1.02 of this Supplemental Indenture may be redeemed at such Regular Redemption Price with moneys remaining in the replacement fund provided for in said Section 4.04 of the Original Indenture.

So long as any Bonds of the Medium Term Note Series III remain outstanding, all references to the minimum provision for depreciation in the form of certificate of available additions set forth in Section 3.03 of the Original Indenture shall be included in any certificate of available additions filed with the Trustee, but whenever Bonds of the Medium Term Note Series III shall no longer be outstanding, all references to such minimum provisions for depreciation may be omitted from any such certificate. SECTION 1.07. I. Each holder of any Bond of the Medium Term 48 18 Note Series III by acceptance of such Bond shall thereby consent that, at any time after the requisite consents, if any, of the holders of Bonds of other series shall have been given as hereinafter provided, Subsections A and G of Section 1.10 of the Original Indenture be amended so as to read as follows: "A. The term `bondable public utility property' shall mean and comprise any tangible property now owned or hereafter acquired by the Company and subjected to the lien of this Indenture, which is located in the States of Oregon, Washington, California, Arizona, New Mexico, Idaho, Montana, Wyoming, Utah and Nevada and is used or is useful to it in the business of furnishing or distributing electricity for heat, light or power or other use, or supplying hot water or steam for heat or power or steam for other purposes, including, without limiting the generality of the foregoing, all properties necessary or appropriate for purchasing, generating, manufacturing, producing, transmitting, supplying, distributing and/or disposing of electricity, hot water or steam; provided, however, that the term `bondable public utility property' shall not be deemed to include any nonbondable property, as defined in Subsection B of this Section 1.10, or any excepted property." "G. The term `minimum provision for depreciation' for the period from March 31, 1945 through December 31, 1966, as applied to bondable public utility property, whether or not subject to a prior lien, shall mean $35,023,487.50. "The term `minimum provision for depreciation' for any calen- dar year subsequent to December 31, 1966, as applied to bondable public utility property, shall mean the greater of (i) an amount equal to 2% of depreciable bondable public utility property, as shown by the books of the Company as of January 1 of such year, with respect to which the Company was as of that date required, in accordance with sound accounting practice, to make appropriations to a reserve or reserves for depreciation or obsolescence, or (ii) the amount actually appropriated by the Company on its books of account to a reserve or reserves for depreciation or obsolescence in respect of depreciable bondable public utility property for such calendar year, in either case less an amount equal to the aggregate of (a) the amount of any property additions which during such calendar year were included in an officers' certificate filed with the Trustee as the basis for a sinking fund credit pursuant to the provisions of a sinking fund for Bonds of any series, and (b) 166-2/3% of the principal amount of Bonds of any series which shall have been delivered to the Trustee as a credit, or which the Company shall have elected to apply as a credit, against any sinking fund payment due during such calendar year for Bonds of any 49 19 series, or which shall have been redeemed in anticipation of, or out of moneys paid to the Trustee on account of, any sinking fund payment due during such calendar year for Bonds of any series. Bonds delivered to the Trustee as, or applied as, a credit against any sinking fund payment and Bonds redeemed in anticipation of any sinking fund payment, regardless of the time when they were actually delivered, applied or redeemed, for purposes of the preceding sentence shall be deemed to have been delivered, applied or redeemed, as the case may be, on the sinking fund payment date when such sinking fund payment was due. Bonds redeemed out of moneys paid to the Trustee on account of any sinking fund payment shall, regardless of the date when they were redeemed, for purposes of the second preceding sentence, be deemed to have been redeemed on the later of (i) the date on which such moneys were paid to the Trustee or (ii) the sinking fund payment date when such sinking fund payment was due. "The minimum provision for depreciation for any calendar year subsequent to December 31, 1966, as applied to bondable public utility property not subject to a prior lien, shall be determined as set forth in the paragraph immediately preceding, except that all references therein to `depreciable bondable public utility property' shall be deemed to be `depreciable bondable public utility property not subject to a prior lien'. "The minimum provision for depreciation as applied to bondable public utility property and the minimum provision for deprecia- tion as applied to bondable public utility property not subject to a prior lien for any period commencing subsequent to December 31, 1966 which is of twelve whole calendar months' duration but is other than a calendar year or which is of less than twelve whole calendar months' duration shall be determined by multiplying the number of whole calendar months in such period by one-twelfth of the corresponding minimum provision for depreciation for the most recent calendar year completed prior to the end of such period, and fractions of a calendar month shall be disregarded. "The aggregate amount of the minimum provision for deprecia- tion as applied to bondable public utility property and the aggregate amount of the minimum provision for depreciation as applied to bondable public utility property not subject to a prior lien from March 31, 1945 to any date shall be the sum of the corresponding minimum provision for depreciation for each completed calendar year between December 31, 1966 and such date, plus the corresponding minimum provision for depreciation for the period, if any, from the end of the most recent such completed calendar year to such date, in each case determined as set forth above, plus $35,023,487.50. "All Bonds credited against any sinking fund payment due sub- sequent 50 20 to December 31, 1966 for Bonds of any series and (except as provided in Section 9.04 with respect to Bonds on which a notation of partial payment shall be made) all Bonds redeemed in anticipation of or out of moneys paid to the Trustee as a part of any sinking fund payment due subsequent to December 31, 1966 for Bonds of any series, shall be canceled and no such Bonds, nor any property additions which, subsequent to December 31, 1966, shall have been included in an officers' certificate filed with the Trustee as the basis for a sinking fund credit pursuant to the provisions of a sinking fund for Bonds of any series, shall be made the basis of the authentication and delivery of Bonds or of any other further action or credit hereunder." II. Each holder of any Bond of the Medium Term Note Series III, by acceptance of such Bond shall thereby consent that, at any time after the requisite consents, if any, of the holders of Bonds of other series shall have been given as hereinafter provided: (1) Subsection A of Section 1.10 of the Original Indenture, as the same may be amended as hereinabove in this Section 1.07 provided, be further amended by replacing the word "and" between the words "Utah" and "Nevada" with a comma and by adding after the word "Nevada" the words "and Alaska"; (2) Subsection G of Section 1.10 of the Original Indenture, as the same may be amended as hereinabove in this Section 1.07 provided, be further amended by amending the second paragraph thereof to read as follows: "The term `minimum provision for depreciation' for any calendar year subsequent to December 31, 1966, as applied to bondable public utility property, shall mean the greater of (i) an amount equal to 2% of depreciable bondable public utility property, as shown by the books of the Company as of January 1 of such year, with respect to which the Company was as of that date required, in accordance with sound accounting practice, to make appropriations to a reserve or reserves for depreciation or obsolescence, or (ii) the amount actually appropriated by the Company on its books of account to a reserve or reserves for depreciation or obsolescence in respect of depreciable bondable public utility property for such calendar year, in either case less an amount equal to the aggregate of (a) the amount of any property additions which during such calendar year were included in an officers' certificate filed with the Trustee as the basis for a sinking fund credit pursuant to the provisions of a sinking fund for Bonds of any series and which as a result of having been so included have 51 21 been deemed, either without time limit or only so long as any Bonds of such series are outstanding, to have been `included in an officers' certificate filed with the Trustee as the basis for a sinking fund credit' and to have been `made the basis for action or credit hereunder' as such term is defined in Subsection H of Section 1.10 of the Original Indenture, and (b) 166-2/3% of the principal amount of Bonds of any series which shall have been delivered to the Trustee as a credit, or which the Company shall have elected to apply as a credit, against any sinking fund payment due during such calendar year for Bonds of any series, or which shall have been redeemed in anticipation of, or out of moneys paid to the Trustee on account of, any sinking fund payment due during such calendar year for Bonds of any series and which as a result of having been so made the basis of a credit upon a sinking fund payment and/or so redeemed by operation of a sinking fund shall have been disqualified, either without time limit or only so long as any Bonds of such series are outstanding, from being made the basis of the authentication and delivery of Bonds or of any other further action or credit under the Original Indenture or any supplemental indenture. Bonds delivered to the Trustee as, or applied as, a credit against any sinking fund payment and Bonds redeemed in anticipation of any sinking fund payment, regardless of the time when they were actually delivered, applied or redeemed, for purposes of the preceding sentence shall be deemed to have been delivered, applied or redeemed, as the case may be, on the sinking fund payment date when such sinking fund payment was due. Bonds redeemed out of moneys paid to the Trustee on account of any sinking fund payment shall, regardless of the date when they were redeemed, for purposes of the second preceding sentence, be deemed to have been redeemed on the later of (i) the date on which such moneys were paid to the Trustee or (ii) the sinking fund payment date when such sinking fund payment was due." (3)Subsection G of Section 1.10 of the Original Indenture, as the same may be amended as hereinabove in this Section 1.07 provided, be further amended by deleting therefrom the last two paragraphs thereof and inserting therein a new last paragraph to read as follows: "The aggregate amount of the minimum provision for depreciation as applied to bondable public utility property and the aggregate amount of the minimum provision for depreciation as applied to bondable public utility property not subject to a prior lien from March 31, 1945 to any date shall be the sum of the corresponding minimum provision for depreciation for each completed calendar year 52 22 between December 31, 1966 and such date, plus (1) the corre- sponding minimum provision for depreciation for the period, if any, from the end of the most recent such completed calendar year to such date, in each case determined as set forth above, plus (2) $35,023,487.50, plus (3) an amount equal to the aggregate of (a) the amount of any property additions which, between December 31, 1966 and such date, became property additions of the character described in clause (a) of the second paragraph of this Subsection G and which, thereafter, also between December 31, 1966 and such date, became `available additions' as a result of the fact that all Bonds of such series ceased to be outstanding, and (b) 166-2/3% of the principal amount of Bonds of any series which, between December 31, 1966 and such date, become Bonds of the character described in clause (b) of the second paragraph of this Subsection G and which, thereafter, also between December 31, 1966 and such date, became `available Bond retirements' as a result of the fact that all Bonds of such series ceased to be outstanding." III. Each holder of any Bond of the Medium Term Note Series III, by acceptance of such Bond shall thereby consent that, at any time after the requisite consents, if any, of the holders of Bonds of other series shall have been given as hereinafter provided: (1) the subparagraph numbered (3) of the third paragraph of Section 1.03 of each of the Sixteenth and the Eighteenth through the Twenty-first Supplemental Indentures and the third paragraph of Section 1.03 of the Twenty-second Supplemental Indenture be amended by inserting before the words "any available additions thus shown as a credit" the phrase "provided, however, that so long as any Bonds of the ........... Series are outstanding" and inserting in the blank space of such phrase the applicable designation of the series of Bonds created by such supplemental indenture; (2)(i) the fifth paragraph of Section 1.03 of the Ninth through the Sixteenth Supplemental Indentures and the Eighteenth through the Twenty-second Supplemental Indentures, which begins with the words "All Bonds made the basis of a credit upon any sinking fund payment for Bonds", (ii) Section 1.03 of the Seventeenth, Twenty-third and Twenty-fourth Supplemental Indentures, (iii) the last sen- tence of the fourth paragraph of Section 1.03 of the First, Third, Fifth, Sixth and Seventh Supplemental Indentures, which begins with the words "All Bonds delivered to the Trustee as part of or to anticipate any sinking fund payment" and (iv) the last sentence of the fourth paragraph of Section 4.03 of the Original Indenture, which 53 23 begins with the words "All Bonds delivered to the Trustee as part of or to anticipate any sinking fund payment", each be amended so as to read as follows: "All Bonds made the basis of a credit upon any sinking fund payment, and/or (except with respect to Bonds on which a notation of partial payment shall be made as permitted by any provision of the Original Indenture, of any supplemental indenture or of any agreement entered into as permitted by the Original Indenture or by any supplemental indenture) redeemed (whether on any sinking fund payment date or in anticipation of any such sinking fund payment) by operation of the sinking fund, for Bonds of the 1975 Series, or for Bonds of the 1977 Series, or for Bonds of the 1977 Second Series, or for Bonds of the 1984 Series, or for Bonds of the 1986 Series, or for Bonds of the 4-7/8% Series due 1987, or for Bonds of the 1990 Series, or for Bonds of the 1991 Series, or for Bonds of the 4-5/8% Series due 1993, or for Bonds of the 4-3/4% Series due 1993, or for Bonds of the 1994 Series, or for Bonds of the 1995 Series, or for Bonds of the 1996 Series, or for Bonds of the 1997 Series, or for Bonds of the 2000 Series, or for Bonds of the 2001 Series, or for Bonds of the 2002 Series, or for Bonds of the 2003 Series, or for Bonds of the 2003 Second Series if not theretofore canceled shall be canceled and, except as otherwise provided in the supplemental indenture creating such series of Bonds, or in another supplemental indenture amending such supplemental indenture, so long as any Bonds of such series are outstanding shall not (but without limiting the use of the principal amount thereof in calculating any minimum provision for depreciation pursuant to the provisions of Subsection G of Section 1.10 of the Original Indenture as the same may be amended in accordance with the provisions of any supplemental indenture) be made the basis of the authentication and delivery of Bonds or of any further action or credit under the Original Indenture or any supplemental indenture.
