FIRST MORTGAGE BOND, 5.15% SERIES DUE 2029

ORIGINAL ISSUE DATE: February 22, 2024

Portland General Electric Company, an Oregon corporation (hereinafter sometimes called the “Company”), for value received, hereby promises to pay to _______________, or registered assigns, the principal sum of _____________________ Dollars on February 22, 2029 (the “Maturity Date”), except to the extent redeemed or repaid prior to the Maturity Date, and to pay interest thereon at the rate of 5.15 percent per annum (calculated on the basis of a 360-day year of twelve 30-day months) until the principal hereof is paid or made available for payment. Interest will be paid semi-annually in arrears on February 22 and August 22 (each an “Interest Payment Date”) each year from the Original Issue Date, which will be the date the first interest period commences, and on the Maturity Date, provided however, that the first Interest Payment Date will be August 22, 2024. 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, and, in the case of an Interest Payment Date, but not the Maturity Date, no additional interest shall accrue. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, subject to certain exceptions, be paid to the person in whose name this bond (or one or more predecessor bonds) is registered at the close of business on the fifteenth day (whether or not a Business Day) next preceding such Interest Payment Date (the “Regular Record Date”); provided, however, that interest payable on the Maturity Date will be payable to the person to whom the principal hereof shall be payable. Should the Company default in the payment of interest (“Defaulted Interest”), the Defaulted Interest shall be paid to the person in whose name this bond (or one or more predecessor bonds) is registered on a subsequent record date fixed by the Company, which subsequent record date shall be fifteen days prior to the payment of such Defaulted Interest. As used herein, “Business Day” means any day,

other than a Saturday or Sunday, on which banks in The City of New York are not required or authorized by law to close.

Payment of the principal of and interest on this bond will be made in immediately available funds at the office or agency of the Trustee located in St. Xxxx, Minnesota or such other office of the Trustee that functions as its financial operations center, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts, with payment at maturity (or, if applicable, upon redemption) made against presentation of this bond at such office or agency for cancellation. The Trustee, as paying agent of the Company, will make all payments of principal and interest by wire transfer of immediately available funds; provided, however, that appropriate written wire transfer instructions must have been received by the Trustee not less than sixteen days prior to the applicable Interest Payment Date, Maturity Date, or redemption date.

Reference is hereby made to the further provisions of this bond set forth on the reverse hereof, including terms of redemption, and such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This bond shall not become or be valid or obligatory for any purpose until the authentication certificate hereon shall have been signed by the Trustee.

In Witness Whereof, Portland General Electric Company has caused this instrument to be executed manually or in facsimile by its duly authorized officers and has caused a facsimile of its corporate seal to be imprinted hereon.

Bonds of the 2029 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 Computershare Trust Company, National Association (as successor to Xxxxx Fargo Bank, National Association), as Trustee, as supplemented, amended, and modified by eighty-one supplemental indentures and by the Eighty-Second Supplemental Indenture (such Indenture of Mortgage and Deed of Trust as so supplemented, amended, and modified by such eighty-one supplemental indentures and the Eighty-Second Supplemental Indenture being hereinafter called the “Indenture”), to which Indenture reference is xxxxxx 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 2029 Series are not subject to any sinking fund.

The Bonds of the 2029 Series may be redeemed by the Company prior to maturity as a whole, at any time, or in part, from time to time on notice given not more than ninety nor less than thirty days prior to the date of such redemption at the option of the Company at a price equal to the greater of (i) the principal amount of the portion of this bond to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest (not including any portion of such payments of interest accrued as of the date of redemption) due on this bond (or portion thereof) to be redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points, together in each case with accrued and unpaid interest to the date of redemption. Notwithstanding the foregoing, so long as no event of default as defined in the Indenture shall then exist, any prepayment made by the Company of all or any portion of the Bonds of the 2029 Series outstanding on or after November 22, 2028 shall be made at 100% of the principal so prepaid plus accrued and unpaid interest to the date of redemption.

If this bond or any portion thereof ($10,000 or an integral multiple thereof) is duly called for redemption and payment duly provided for as specified in the Indenture, this bond or such portion thereof shall cease to be entitled to the lien of the Indenture from and after the date payment is so provided for and shall cease to bear interest from and after the date fixed for 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 if the modifications or alterations would adversely affect or diminish the rights of the holders of any bonds against the Company or its property; provided, however, that no such modification or alteration shall be made without the written approval or consent of all holders 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 St. Xxxx, Minnesota, 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 $100,000 or any amount in excess thereof that is an integral multiple of $10,000. 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. Bonds may be issued in a denomination of less than $100,000 (but in multiples of at least $10,000) if necessary to enable the registration of a transfer by a holder of its entire holding of bonds, or if necessary for the redemption of bonds.

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 (exclusive of bonds disqualified by reason of the Company’s interest therein) at 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 2029 SERIES AND
CERTAIN PROVISIONS RELATING THERETO.

SECTION 1.01 Certain Terms of Bonds of the 2029 Series. There is hereby established a series of First Mortgage Bonds of the Company designated and entitled as “First Mortgage Bonds, 5.15% Series due 2029” (sometimes referred to as the “Bonds of the 2029 Series”). The aggregate principal amount of the Bonds of the 2029 Series shall be limited to $100,000,000, excluding, however, any Bonds of the 2029 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.

The definitive Bonds of the 2029 Series shall be issuable in substantially the form as hereinabove set forth in fully registered form without coupons in the denomination of $100,000, or any amount in excess thereof that is an integral multiple of $10,000.

Notwithstanding the provisions of Section 2.05 of the Mortgage, each Bond of the 2029 Series shall be dated as of the date sold by the Company (the “Original Issue Date”) and shall mature on February 22, 2029, (the “Maturity Date”), except to the extent redeemed or repaid prior to the Maturity Date. Each Bond of the 2029 Series shall bear interest from the Original Issue Date, which is the date the first interest period commences, at the rate of 5.15 per cent per annum (calculated on the basis of a 360-day year of twelve 30-day months), until payment of the principal thereof has been paid or made available for payment. Interest will be payable semi-annually in arrears on February 22 and August 22 (each an “Interest Payment Date”) each year commencing on August 22, 2024, and on the Maturity Date. 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, and, in the case of an Interest Payment Date, but not the Maturity Date, no additional interest shall accrue. The person in whose name any Bond of the 2029 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 2029 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 of the 2029 Series is registered on a subsequent record date fixed by the Company, which subsequent record date shall be fifteen 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 thereof shall be payable. As used herein the term “Business Day” means any day, other than a Saturday or Sunday, on which banks in The City of New York, New York are not required or authorized by law to close. 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 the Bonds of the 2029 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 Trustee located in St. Xxxx, Minnesota or such other

office of the Trustee that functions as its financial operations center, and interest on such Bonds of the 2029 Series shall be payable in like coin or currency at said office or agency, with payment at maturity (or, if applicable, upon redemption) made against presentation of such Bonds for cancellation.

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 2029 Series may be exchanged for a new Bond or Bonds of the 2029 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 2029 Series.

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 2029 Series, but the Company or the Trustee at either of their 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 2029 Series. The Bonds of the 2029 Series may be redeemed prior to maturity at any time, in whole or in part, upon prior notice given by mailing such notice to the respective registered owners of such Bonds of the 2029 Series not less than thirty nor more than ninety days prior to the redemption date and as otherwise required by the provisions of Article Nine of the Mortgage, at the option of the Company, at a redemption price equal to the greater of (i) 100 percent of the principal amount of the portion of the Bonds of the 2029 Series to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest (not including any portion of such payments of interest accrued as of the date of redemption) due on the Bonds of the 2029 Series (or portion thereof) to be redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points, together in each case with accrued and unpaid interest to the date of redemption. Notwithstanding the foregoing, so long as no event of default as defined in the Indenture shall then exist, any prepayment made by the Company of all or any portion of the Bonds of the 2029 Series outstanding on or after November 22, 2028 shall be made at 100% of the principal so prepaid plus accrued and unpaid interest to the date of redemption. The Company shall give the Trustee notice of such redemption price immediately after the calculation thereof, and the Trustee shall have no responsibility for such calculation.

Notwithstanding the provisions of Section 9.03 of the Mortgage, in the case of any partial redemption of the Bonds of the 2029 Series, the principal amount of the Bonds to be redeemed shall be allocated pro rata among all holders of such Bonds of the 2029 Series at the time outstanding and in accordance with the unpaid principal amount thereof.

The following definitions shall apply for purposes of this Section 1.02:

(a) “Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the redemption date.

ARTICLE TWO
BONDS OF THE 2034 SERIES AND
CERTAIN PROVISIONS RELATING THERETO.

SECTION 2.01 Certain Terms of Bonds of the 2034 Series. There is hereby established a series of First Mortgage Bonds of the Company designated and entitled as “First Mortgage Bonds, 5.36% Series due 2034” (sometimes referred to as the “Bonds of the 2034 Series”). The aggregate principal amount of the Bonds of the 2034 Series shall be limited to $100,000,000, excluding, however, any Bonds of the 2034 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.

The definitive Bonds of the 2034 Series shall be issuable in substantially the form as hereinabove set forth in fully registered form without coupons in the denomination of $100,000, or any amount in excess thereof that is an integral multiple of $10,000.

Notwithstanding the provisions of Section 2.05 of the Mortgage, each Bond of the 2034 Series shall be dated as of the date sold by the Company (the “Original Issue Date”) and shall mature on February 22, 2034, (the “Maturity Date”), except to the extent redeemed or repaid prior to the Maturity Date. Each Bond of the 2034 Series shall bear interest from the Original

Issue Date, which is the date the first interest period commences, at the rate of 5.36 per cent per annum (calculated on the basis of a 360-day year of twelve 30-day months), until payment of the principal thereof has been paid or made available for payment. Interest will be payable semi-annually in arrears on February 22 and August 22 (each an “Interest Payment Date”) each year commencing on August 22, 2024 and on the Maturity Date. 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, and, in the case of an Interest Payment Date, but not the Maturity Date, no additional interest shall accrue. The person in whose name any Bond of the 2034 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 2034 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 of the 2034 Series is registered on a subsequent record date fixed by the Company, which subsequent record date shall be fifteen 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 thereof shall be payable. As used herein the term “Business Day” means any day, other than a Saturday or Sunday, on which banks in The City of New York, New York are not required or authorized by law to close. 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 the Bonds of the 2034 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 Trustee located in St. Xxxx, Minnesota or such other office of the Trustee that functions as its financial operations center, and interest on such Bonds of the 2034 Series shall be payable in like coin or currency at said office or agency, with payment at maturity (or, if applicable, upon redemption) made against presentation of such Bonds for cancellation.

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 2034 Series may be exchanged for a new Bond or Bonds of the 2034 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 2034 Series.

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 2034 Series, but the Company or the Trustee at either of their option may require payment of a sum sufficient to cover any tax or other governmental charge incident thereto.

SECTION 2.02 Redemption Provisions for Bonds of the 2034 Series. The Bonds of the 2034 Series may be redeemed prior to maturity at any time, in whole or in part, upon prior notice given by mailing such notice to the respective registered owners of such Bonds of the 2034 Series not less than thirty nor more than ninety days prior to the redemption date and as otherwise required by the provisions of Article Nine of the Mortgage, at the option of the Company, at a redemption price equal to the greater of (i) 100 percent of the principal amount of the portion of the Bonds of the 2034 Series to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest (not including any portion of such payments of interest accrued as of the date of redemption) due on the Bonds of the 2034 Series

(or portion thereof) to be redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points, together in each case with accrued and unpaid interest to the date of redemption. Notwithstanding the foregoing, so long as no event of default as defined in the Indenture shall then exist, any prepayment made by the Company of all or any portion of the Bonds of the 2034 Series outstanding on or after November 22, 2033 shall be made at 100% of the principal so prepaid plus accrued and unpaid interest to the date of redemption. The Company shall give the Trustee notice of such redemption price immediately after the calculation thereof, and the Trustee shall have no responsibility for such calculation.

Notwithstanding the provisions of Section 9.03 of the Mortgage, in the case of any partial redemption of the Bonds of the 2034 Series, the principal amount of the Bonds to be redeemed shall be allocated pro rata among all holders of such Bonds of the 2034 Series at the time outstanding and in accordance with the unpaid principal amount thereof.
