Ladies and Gentlemen:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. *Introductory.* PacifiCorp, an Oregon corporation (the "**Company**"), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters listed in <u>Schedule A</u> hereto (the "**Underwriters**") U.S. $400,000,000 principal amount of its First Mortgage Bonds, 4.250% Series due 2029 (the "**Offered Securities**"), to be issued under that certain Mortgage and Deed of Trust, dated as of January 9, 1989, with The Bank of New York Mellon Trust Company, N.A., as successor trustee (the "**Trustee**"), as heretofore amended and supplemented by the supplemental indentures thereto and as further amended and supplemented by a supplemental indenture to be dated as of the Closing Date (as defined below) (collectively, the "**Mortgage**") pursuant to the registration statement on Form S-3 (File No. 333-281019) filed on July 25, 2024, as amended to date (the "**Initial Registration Statement**"). The Mortgage has been qualified under the U.S. Trust Indenture Act of 1939, as amended (the "**Trust Indenture Act**"), and the rules and regulations of the U.S. Securities and Exchange Commission (the "**Commission**") under the Trust Indenture Act. The U.S. Securities Act of 1933, as amended, is herein referred to as the "**Securities Act**," and the rules and regulations of the Commission thereunder are herein referred to as the "**Rules and Regulations**."

The Company hereby agrees with the several Underwriters as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. *Representations and Warranties of the Company.* The Company represents and warrants to, and agrees with, the several Underwriters that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Initial Registration Statement in respect of the Offered Securities has been filed with the Commission; the Initial Registration Statement and any post-effective amendments thereto prior to the date hereof, each in the form heretofore delivered or to be delivered to the Underwriters and, excluding exhibits to the Initial Registration Statement but including all documents incorporated by reference in the prospectus contained in such Initial Registration Statement (the "**Base Prospectus**"), including any prospectus supplement relating to the Offered Securities that is filed with the Commission and deemed by virtue of Rule 430B under the Securities Act to be part of the Initial Registration Statement, became effective upon filing with the Commission; other than a registration statement, if any, increasing the size of the offering (a "**Rule 462(b) Registration Statement,**" together with the Initial Registration Statement, the "**Registration Statement**"), filed pursuant to Rule 462(b) under the Securities Act, which, if so filed, became effective upon filing, no other document with respect to the Initial Registration Statement or any document incorporated by reference therein has heretofore been filed or transmitted for filing with the Commission with respect to the offering contemplated by the Initial Registration Statement (other than documents filed after the filing date of the Initial Registration Statement under the U.S. Securities Exchange Act of 1934, as amended (the "**Exchange Act**"), and prospectuses filed pursuant to Rule 424(b) of the Rules and Regulations, each in the form heretofore delivered to the Underwriters); and no stop order suspending the effectiveness of the Initial Registration Statement, any post-effective amendment thereto or the Rule 462(b) Registration Statement, if any, has been issued and no proceeding for that purpose has been initiated or threatened by the Commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) A preliminary prospectus supplement relating to the Offered Securities has been prepared by the Company and a final prospectus supplement relating to the Offered Securities will be prepared by the Company in accordance with Section 5(a) hereto. Such preliminary prospectus supplement (including the documents incorporated by reference therein), together with the Base Prospectus, is hereinafter referred to as the "**Preliminary Prospectus**;" such final prospectus supplement relating to the Offered Securities to be filed with the Commission pursuant to Rule 424(b) under the Securities Act (including the documents incorporated by reference therein), together with the Base Prospectus, is hereinafter referred to as the "**Prospectus.**" The Preliminary Prospectus, as amended or supplemented as of the Applicable Time (as defined below), when considered together with the final term sheet filed pursuant to Section 5(a) hereof (the "**Disclosure Package**"), as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as of its date and as amended or supplemented as of the Closing Date, does not and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and each Issuer Free Writing Prospectus (as defined in Rule 433 under the Securities Act) listed on <u>Schedule B(i)</u> hereto and the Fixed Income Investor Presentation dated February 2026 (the "**Additional Materials**") does not conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus and each such Issuer Free Writing Prospectus and the Additional Materials, as supplemented by and taken together with the Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; *provided*, the preceding two sentences do not apply to statements in or omissions from the Preliminary Prospectus, the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or Additional Materials based upon written information furnished to the Company by the Underwriters specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 7(b) hereof. For purposes of this Agreement, the "**Applicable Time**" is 2:35 p.m., New York City time, on the date of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) At the earliest time after the filing of the Initial Registration Statement that the Company or another offering participant made a *bona fide* offer (within the meaning of Rule 164(h)(2) under the Securities Act) of the Offered Securities, the Company was not an "ineligible issuer" as defined in Rule 405 under the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Registration Statement and the Prospectus conform, and any further amendments or supplements to the Registration Statement or the Prospectus when made will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations and the Registration Statement conforms, and any further amendments or supplements to the Registration Statement when made will conform, in all material respects to the requirements of the Trust Indenture Act, and the rules and regulations of the Commission thereunder. The Registration Statement, as of the applicable effective date, and any amendments thereto as of the Closing Date did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Oregon with corporate power and corporate authority (i) to own its properties and conduct its business as described in the Disclosure Package and the Prospectus and (ii) to execute and deliver, and perform its obligations under, this Agreement, the Mortgage and the Offered Securities; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which it owns or leases substantial properties or in which the conduct of its business requires such qualification, except where the failure to so qualify would not have a material adverse effect on the financial condition, business or results of operations of the Company and its subsidiaries taken as a whole (a "**Material Adverse Effect**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Mortgage has been duly authorized, and when duly executed and delivered by the Company, shall constitute a valid and legally binding instrument of the Company enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law); and the Mortgage conforms to the description thereof in the Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The documents incorporated by reference in the Prospectus and the Disclosure Package, at the time they were or hereafter are filed with the Commission, complied or when so filed will comply, as the case may be, in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and, when read together with the other information in the Prospectus and the Disclosure Package, did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were or are made, not misleading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Offered Securities have been duly authorized by the Company and, when authenticated and delivered in accordance with the Mortgage and paid for by the purchasers thereof, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law), and will be entitled to the benefit of the security afforded by the Mortgage; and the Offered Securities conform to the description thereof in the Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) No consent, approval, authorization or order of, or filing or registration by the Company with, any court, governmental agency or third party is required for the consummation of the transactions contemplated by this Agreement and the Mortgage in connection with the issuance and sale of the Offered Securities by the Company and the use of the proceeds of the offering of the Offered Securities as described in the Disclosure Package and the Prospectus, except such as have been obtained or made or except as such may be required under (1) state or foreign securities laws, or (2) the rules and regulations of the Financial Industry Regulatory Authority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) This Agreement has been duly authorized, executed and delivered by the Company and is a valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and subject to any principles of public policy limiting the right to enforce the indemnification and contribution provisions contained herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) Except as disclosed in the Disclosure Package and the Prospectus, the Company has good and sufficient title to all the material properties described as owned and good and sufficient leasehold interest in all of the properties described as leased by it (the "**Properties**"), subject to minor defects and irregularities customarily found in properties of like size and character that do not materially impair the use of the property affected thereby in the operation of the business of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) The Company is not (i) in violation of its Fourth Restated Articles of Incorporation, as amended (the "**Articles**") or its Bylaws, as amended, (ii) in default in the performance or observance of any material obligation, covenant or condition contained in any contract, agreement or other instrument to which it is a party or by which it may be bound or (iii) in violation of any order, rule or regulation applicable to the Company of any court or any federal or state regulatory body or administrative agency or other governmental body, the effect of which, in the case of (ii) and (iii), would result in a Material Adverse Effect, and neither the execution and delivery of this Agreement, the Mortgage, or the Offered Securities, the consummation of the transactions herein or therein contemplated, the fulfillment of the terms hereof or thereof nor compliance with the terms and provisions hereof or thereof will conflict with, or result in a breach of, or constitute a default under (x) the Articles or such Bylaws, or any material contract, agreement or other instrument to which it is now a party or by which it may be bound or (y) any order, rule or regulation applicable to the Company of any court or any federal or state regulatory body or administrative agency or other governmental body having jurisdiction over the Company or over its properties, the effect of which, singly or in the aggregate, would have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) Except as disclosed in the Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending or to the Company's knowledge threatened against the Company or its subsidiaries that, if determined adversely to the Company or any subsidiary would be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect or a material adverse effect on the ability of the Company to perform its obligations under this Agreement or the Mortgage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) The consolidated financial statements included or incorporated by reference in the Disclosure Package and the Prospectus present fairly the financial condition and operations of the Company and its consolidated subsidiaries at the respective dates or for the respective periods to which they apply; such financial statements have been prepared in each case in accordance with generally accepted accounting principles consistently applied throughout the periods involved except as otherwise indicated in the Disclosure Package and the Prospectus; and Deloitte & Touche LLP, who has examined certain audited financial statements of the Company, is an independent registered public accounting firm as required by the Securities Act and the Regulations thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) Except as reflected in, or contemplated by, the Disclosure Package and the Prospectus, since the respective most recent dates as of which information is given in the Disclosure Package and the Prospectus, there has not been any change in the capital stock or long-term debt of the Company (other than changes arising from transactions in the ordinary course of business), or any material adverse change in the business, affairs, business prospects, property or financial condition of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, and since such dates there has not been any material transaction entered into by the Company other than transactions contemplated by the Disclosure Package and the Prospectus, and transactions in the ordinary course of business; and the Company has no material contingent obligation that is not disclosed in the Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) There is and has been no failure on the part of the Company or, to the knowledge of the Company, any of the Company's directors or executive officers in their respective capacities as such, to comply in all material respects with the provisions of the U.S. Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(s) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or other representative authorized to act on behalf of the Company or any of its subsidiaries, has in the course of its actions for, or on behalf of, the Company (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government officials, "foreign office" as defined in the United States Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (collectively, the "**FCPA**") or employee from corporate funds; (iii) violated or is in violation of any provision of the FCPA, the Bribery Act 2010 of the United Kingdom, as amended, or any other applicable anti-bribery or anti-corruption law or statutes; or (iv) made any bribe, rebate, payoff, influence, payment, kickback or other unlawful payments to any domestic government official, foreign official or employee; and each of the Company and its subsidiaries has conducted its business in compliance with the FCPA, the Bribery Act 2010 of the United Kingdom, as amended, and any other applicable anti-bribery or anti-corruption laws or statutes, and has instituted and maintains policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Preliminary Prospectus, the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus, or the Additional Materials or any amendment or supplement to the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or the Additional Materials arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made (in the case of the Registration Statement, necessary in order to make the statements therein not misleading), not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Representatives on behalf of the Underwriters specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Preliminary Prospectus and Prospectus furnished on behalf of each Underwriter: under the caption "Underwriting (Conflicts of Interest)," paragraphs 3, 4 (second sentence only), 5, 6 and 7; *provided, however,* that the Underwriters shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company's failure to perform its obligations under Section 5(a) of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through forfeiture or impairment of procedural or substantive rights or defenses) by such failure; and *provided further* that the failure to notify the indemnifying party pursuant to this Section 7(c) shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; *provided, however*, that the indemnified party shall have the right to employ counsel to represent the indemnified party and their respective controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 7 if the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, if in the written opinion of counsel to either the indemnifying party or the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them or the indemnifying party shall have failed to employ counsel within a reasonable period of time, and in that event the fees and expenses of one firm of separate counsel (in addition to the fees and expenses of one local counsel in each applicable jurisdiction) shall be paid by the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Underwriters with respect to the Offered Securities from the Company under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. *Default of Underwriters.* If any Underwriter or Underwriters defaults in its or their obligations to purchase the Offered Securities hereunder and the aggregate principal amount of the Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Offered Securities, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including themselves, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase such Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so defaults and the aggregate principal amount of the Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Offered Securities and arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of the non-defaulting Underwriters or the Company, except as provided in Section 9. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein, including the Company's obligations pursuant to Section 9 hereof, will relieve a defaulting Underwriter from liability for its default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. *Survival of Certain Representations and Obligations.* The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated other than such default by an Underwriter, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Underwriters pursuant to Section 7 shall remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of (x) the termination of this Agreement pursuant to Section 8 or (y) the occurrence of any event specified in clause (iii), (v), (vi) or (vii) of Section 6(c), the Company will reimburse the Underwriters for all accountable out-of-pocket expenses (including fees and disbursements of counsel) actually incurred by them in connection with the offering of the Offered Securities, provided that the Company shall not be obligated under this Section 9 to reimburse the Underwriters for any expenses (including any reasonable fees and disbursements of counsel) in excess of $200,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. *No Fiduciary Duty*. The Company acknowledges and agrees that in connection with this offering or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists in connection with the offering of the Offered Securities; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company in connection with the offering of the Offered Securities and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company in connection with the offering of the Offered Securities shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters related to such transactions will be performed solely for the benefit of the Underwriters and not on behalf of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. *Notices.* All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or faxed and confirmed to each of (i) Barclays Capital Inc. at 745 Seventh Avenue, New York, NY 10019, Attention: Syndicate Registration, facsimile: 646-834-8133; (ii) Citigroup Global Markets Inc. at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, facsimile: (646) 291-1469; (iii) J.P.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise.

Purchasers of bonds who wish to trade bonds prior to the date that is one business day preceding the settlement date should consult their own advisors. |

**EXHIBIT A**

Form of Opinion of Angie G. Burcham, Assistant General Counsel and Corporate Secretary of the Company

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To my knowledge and except for the matters disclosed in the Disclosure Package, there is no legal or governmental action, suit or proceeding before any court, governmental agency, body or authority, domestic or foreign, now pending or threatened against or involving the Company or any subsidiary of the Company that, if determined adversely to the Company and its subsidiaries, taken as a whole, is reasonably likely to have, individually or in the aggregate, a material adverse effect on the business, affairs, property or financial condition of the Company and its subsidiaries taken as a whole or a material adverse effect on the ability of the Company to perform its obligations under the Underwriting Agreement, the Mortgage or the Bonds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The execution, delivery and performance of the Underwriting Agreement and the Mortgage and the issuance and sale of the Bonds and the use of proceeds of the Bonds as designated in the Prospectus do not and will not (A) conflict with the Articles of Incorporation or By-laws of the Company, (B) to my knowledge, conflict with, result in the creation or imposition of any lien, charge or other encumbrance, other than the Mortgage, upon any asset of the Company pursuant to the terms of, or constitute a breach of, or default under, any agreement, indenture or other instrument to which the Company is a party, or by which the Company is bound or to which any of its properties are subject or (C) to my knowledge, result in a violation of any statute, rule or regulation, or any order, judgment or decree known to me of any court or governmental agency, body or authority having jurisdiction over the Company or any of its properties, where any such conflict, encumbrance, breach, default or violation under clause (B) or (C) is reasonably likely to have, individually or in the aggregate, a material adverse effect on the business, affairs, property or financial condition of the Company and its subsidiaries taken as a whole.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To my knowledge, except for such consents, approvals, authorizations, registrations or qualifications as may be required under the Securities Act, the Trust Indenture Act or state securities or blue sky laws or as may be required by applicable state public utility commissions and under the Federal Power Act, no consent, authorization or order of, or filing or registration by the Company with, any court, governmental agency or third party is required in connection with the execution, delivery and performance by the Company of the Underwriting Agreement and the Mortgage, the consummation of the transactions contemplated herein and therein, and the ssuance, distribution and sale of the Bonds as contemplated therein, in each case where the effect of the failure to obtain such approval, authorization, consent or order, or make such filing, is material to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Company has good and sufficient title to the Properties subject to the Mortgage, which include substantially all of the permanent physical properties of the Company (other than those expressly excepted), subject only to Excepted Encumbrances and defects and irregularities customarily found in properties of like size and character that, in my opinion, do not materially impair the use of the property affected thereby in the operation of the business of the Company; the descriptions in the Mortgage of such of the Properties as are described therein are adequate for the Mortgage to constitute a lien thereon; the Mortgage constitutes a valid lien in favor of the Trustee for the benefit of the holders of the bonds issued pursuant to the Mortgage and, to the best of my knowledge, there is no lien on such Properties prior or equal to the lien of the Mortgage, other than the exceptions enumerated above in this paragraph 4.

**EXHIBIT B**

Form of Opinion of Perkins Coie LLP, special counsel to the Company

&nbsp;&nbsp;&nbsp;&nbsp;1. The Company is a corporation validly existing under the laws of Oregon, with the corporate power and authority to own its properties
and conduct its business as described in the Preliminary Prospectus and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;2. Based solely on the certificates attached as Schedule B, the Company is qualified to transact business as a foreign corporation in
Arizona, Colorado, Idaho, Montana, New Mexico, Utah, Washington and Wyoming.

&nbsp;&nbsp;&nbsp;&nbsp;3. The Company has the corporate power and authority to enter into the Underwriting Agreement and the Supplemental Indenture, to issue
the Bonds and to consummate the transactions contemplated by the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;4. Each of the Underwriting Agreement and the Supplemental Indenture has been duly authorized, executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;5. The Mortgage constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

&nbsp;&nbsp;&nbsp;&nbsp;6. The Mortgage has been duly qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

&nbsp;&nbsp;&nbsp;&nbsp;7. The Bonds are in the form contemplated by the Mortgage, have been duly authorized by the Company for issuance and sale pursuant to
the Underwriting Agreement and the Mortgage, have been duly executed by the Company and, when authenticated by the Trustee in the manner
provided in the Mortgage and delivered against payment of the purchase price therefore pursuant to the Underwriting Agreement, will constitute
valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and entitled to the benefits
of the Mortgage.

&nbsp;&nbsp;&nbsp;&nbsp;8. The statements in the Preliminary Prospectus and the Prospectus under the captions "Description of the Bonds" and "Description
of Additional Bonds" insofar as they purport to summarize the provisions of the Mortgage and the Bonds, fairly summarize such provisions
in all material respects. The statements in the Preliminary Prospectus and the Prospectus under the caption "Certain U.S. Federal
Income Tax Considerations," insofar as such statements purport to constitute summaries of United States federal income tax law and
regulations or legal conclusions with respect thereto, fairly summarize the matters described therein in all material respects.

&nbsp;&nbsp;&nbsp;&nbsp;9. No approval, authorization, consent or order of, or filing with any governmental authority is required in connection with the issuance
and sale of the Bonds by the Company, the consummation by the Company of the transactions contemplated by the Underwriting Agreement,
the due authorization, execution or delivery of the Underwriting Agreement or the due execution, delivery or performance of the Mortgage
by the Company, in each case where the effect of the failure to obtain such approval, authorization, consent or order, or to make such
filing, could reasonably be expected to have a Material Adverse Effect and except (a) as may be required under federal or state "blue
sky" securities laws and regulations, (b) such as have been obtained or made or (c) as required under Public Utility Regulations
(as defined in paragraph D-7 below).

&nbsp;&nbsp;&nbsp;&nbsp;10. The Idaho Public Utilities Commission and the Public Utility Commission of Oregon have entered appropriate orders, which to our knowledge
remain in full force and effect on the date of this letter, each authorizing the issuance of the Bonds by the Company; the Company has
filed a notice with the Washington Utilities and Transportation Commission regarding the issuance and sale of the Bonds that complies
with the filing requirements of RCW 80.08.040 and WAC 480-100-242; the Company has filed a notice of proposed securities issuance with
the Idaho Public Utilities Commission regarding the issuance and sale of the Bonds; and, together with certain exemptive orders that have
been issued by each of the Public Utilities Commission of the State of California, the Public Service Commission of Utah and the Public
Service Commission of Wyoming (each of which to our knowledge remains in full force and effect on the date of this letter), such orders
and notices constitute the only approval, authorization, consent or other order of, or notification to, any governmental body legally
required in connection with the regulation of the Company as a public utility for the authorization of the issuance of the Bonds by the
Company pursuant to the terms of the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;11. The Registration Statement was declared immediately effective under the Securities Act on July 25, 2024; the Prospectus was filed
with the Commission pursuant to Rule 424(b) on February 5, 2026 in a manner and within the time period required by Rule 424(b) under
the Securities Act; and, based solely on a review of the contents of the Commission's stop orders webpage located at www.sec.gov/enforcement-litigation/stop-orders,
as of the date hereof, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act
and, to our knowledge, no proceedings for that purpose have been initiated by the Commission.

&nbsp;&nbsp;&nbsp;&nbsp;12. Without independent verification of the factual accuracy, completeness or fairness of any statements made in the Registration Statement,
Preliminary Prospectus and the Prospectus, the Registration Statement, as of its effective date, and the Preliminary Prospectus, as of
its date, including in each case the information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, and
the Prospectus, as of its date, each appear on its face to be appropriately responsive in all material respects with the applicable requirements
of the Securities Act and the rules thereunder; it being understood, however, that we express no view with respect to the financial
statements, schedules, other financial data, or exhibits included or incorporated by reference in, or omitted from, the Registration Statement,
the Preliminary Prospectus or the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;13. The Company is not, and, immediately after giving effect to the issuance and sale of the Bonds in accordance with the Underwriting
Agreement and to the application of the net proceeds received by the Company from the offering and sale of the Bonds as described in the
Preliminary Prospectus and the Prospectus, will not, be required to register as an "investment company" within the meaning
of the Investment Company Act.

TO HAVE AND TO HOLD all such properties, real, personal and mixed, mortgaged and pledged, or in which a security interest has been granted by the Company as aforesaid, or intended so to be (subject, however, to Excepted Encumbrances as defined in Section 1.06 of the Mortgage), unto The Bank of New York Mellon Trust Company, N.A., as Trustee, and its successors and assigns forever;

IN TRUST NEVERTHELESS, for the same purposes and upon the same terms, trusts and conditions and subject to and with the same provisos and covenants as are set forth in the Mortgage, this Thirty-Sixth Supplemental Indenture being supplemental to the Mortgage;

AND IT IS HEREBY COVENANTED by the Company that all the terms, conditions, provisos, covenants and provisions contained in the Mortgage shall affect and apply to the property hereinbefore described and conveyed, and to the estates, rights, obligations and duties of the Company and the Trustee and the beneficiaries of the trust with respect to said property, and to the Trustee and its successor or successors in the trust, in the same manner and with the same effect as if the said property had been owned by the Company at the time of the execution of the Mortgage, and had been specifically and at length described in and conveyed to said Trustee by the Mortgage as a part of the property therein stated to be conveyed.

The Company further covenants and agrees to and with the Trustee and its successor or successors in such trust under the Mortgage, as follows:

**ARTICLE I**

**Fifty-Sixth Series of Bonds**

*SECTION 1.01.* There shall be a series of bonds designated "4.250% Series due 2029" (herein sometimes referred to as the Fifty-Sixth Series), each of which shall also bear the descriptive title "First Mortgage Bond," and the form thereof, which shall be established by or pursuant to a Resolution, shall contain suitable provisions with respect to the matters hereinafter in this Section specified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(I) Bonds of the Fifty-Sixth Series shall mature on March 15, 2029 and shall be issued as fully registered bonds in the minimum denomination of two thousand dollars and, at the option of the Company, any multiple or multiples of one thousand dollars in excess thereof (the exercise of such option to be evidenced by the execution and delivery thereof).

The Company reserves the right to establish, at any time, by or pursuant to a Resolution filed with the Trustee, a form of coupon bond, and or appurtenant coupons, for the Fifty-Sixth Series and to provide for exchangeability of such coupon bonds with the bonds of the Fifty-Sixth Series issued hereunder in fully registered form and to make all appropriate provisions for such purpose.

Bonds of the Fifty-Sixth Series need not be issued at the same time and such series may be reopened at any time, without notice to or the consent of any then-existing holder or holders of any bond of the Fifty-Sixth Series, for issuances of additional bonds of the Fifty-Sixth Series in an unlimited principal amount. Any such additional bonds will have the same interest rate, maturity and other terms as those initially issued, except for payment of interest accruing prior to the original issue date of such additional bonds and, if applicable, for the first interest payment date following such original issue date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(II) Bonds of the Fifty-Sixth Series shall bear interest at the rate of four and twenty-five hundredths per centum (4.250%) per annum payable semi-annually in arrears on March 15 and September 15 of each year (each, an "Interest Payment Date"). Bonds of the Fifty-Sixth Series shall be dated and shall accrue interest as provided in Section 2.06 of the Mortgage.

The initial Interest Payment Date is September 15, 2026. The amount of interest payable will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any date on which interest is payable on any bond of the Fifty-Sixth Series is not a Business Day, then payment of the interest payable on that date will be made on the next succeeding day which is a Business Day (and without any additional interest or other payment in respect of any delay), with the same force and effect as if made on such date.

Interest payable on any bond of the Fifty-Sixth Series and punctually paid or duly provided for on any Interest Payment Date for such bond will be paid to the person in whose name the bond is registered at the close of business on the Record Date (as hereinafter specified) for such bond next preceding such Interest Payment Date; *provided*, *however*, that interest payable at maturity or upon earlier redemption will be payable to the person to whom principal shall be payable. So long as the bonds of the Fifty-Sixth Series remain in book-entry only form, the "Record Date" for each Interest Payment Date shall be the close of business on the Business Day before the applicable Interest Payment Date. If the bonds of the Fifty-Sixth Series are not in book-entry only form, the Record Date for each Interest Payment Date shall be the close of business on the 1st calendar day of the month in which the applicable Interest Payment Date occurs (whether or not a Business Day).

"*Business Day*" means, for purposes of this Section (II), a day other than (i) a Saturday or a Sunday, or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

Any interest on any bond of the Fifty-Sixth Series which is payable but is not punctually paid or duly provided for, on any Interest Payment Date for such bond (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered owner on the relevant Record Date for the payment of such interest solely by virtue of such owner having been such owner; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Interest on the bonds of the Fifty-Sixth Series to the persons in whose names such bonds are registered at the close of business on a Special Record Date (as hereinafter defined) for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Company shall, at least 30 days prior to the proposed date of payment, notify the Trustee in writing (signed by an Authorized Financial Officer of the Company) of the amount of Defaulted Interest proposed to be paid on each bond of the Fifty-Sixth Series and the date of the proposed payment (which date shall be such as will enable the Trustee to comply with the next sentence hereof), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this subsection provided and not to be deemed part of the Mortgaged and Pledged Property. Thereupon, the Trustee shall fix a record date (herein referred to as a "Special Record Date") for the payment of such Defaulted Interest which date shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each registered owner of a bond of the Fifty-Sixth Series at his, her or its address as it appears in the bond register not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the bonds of the Fifty-Sixth Series are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following subsection (ii).

(ii) The Company may make payment of any Defaulted Interest on the bonds of the Fifty-Sixth Series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such bonds may be listed and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this subsection, such payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each bond of the Fifty-Sixth Series delivered under the Mortgage upon transfer of or in exchange for or in lieu of any other bond shall carry all rights to interest accrued and unpaid, and to accrue, which were carried by such other bond and each such bond shall bear interest from such date, that neither gain nor loss in interest shall result from such transfer, exchange or substitution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(III) The principal of and interest and premium, if any, on each bond of the Fifty-Sixth Series shall be payable 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 or in such other currency or currency unit as shall be determined by or in accordance with the Resolution filed with the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(IV) Bonds of the Fifty-Sixth Series shall not be redeemable prior to maturity at the option of any holder or holders of such bonds. Bonds of the Fifty-Sixth Series shall be redeemable, in whole or in part, at any time and from time to time prior to maturity at the option of the Company. Prior to February 15, 2029 (one month prior to their maturity date) (the "par call date"), the redemption price (expressed as a percentage of principal amount and rounded to three decimal places) shall include accrued and unpaid interest to the redemption date on the bonds to be redeemed, plus the greater of (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the bonds matured on the par call date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 10 basis points less (b) interest accrued to the date of redemption. On or after the par call date, the redemption price shall be equal to one hundred percent (100%) of the principal amount of bonds of this series then Outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date.

"*Treasury Rate*" means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily) - H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the par call date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the par call date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the par call date, as applicable. If there is no United States Treasury security maturing on the par call date but there are two or more United States Treasury securities with a maturity date equally distant from the par call date, one with a maturity date preceding the par call date and one with a maturity date following the par call date, the Company shall select the United States Treasury security with a maturity date preceding the par call date. If there are two or more United States Treasury securities maturing on the par call date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company's actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee shall have no responsibility for the calculation of the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the redemption date to each holder of bonds to be redeemed at its registered address.

In the case of a partial redemption, selection of the bonds for redemption will be made by lot. No bonds of a principal amount of $2,000 or less will be redeemed in part. If any bond is to be redeemed in part only, the notice of redemption that relates to the bond will state the portion of the principal amount of the bond to be redeemed. A new bond in a principal amount equal to the unredeemed portion of the bond will be issued in the name of the holder of the bond upon surrender for cancellation of the original bond. For so long as the bonds are held by The Depository Trust Company (or another depositary), the redemption of the bonds shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the bonds or portions thereof called for redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(V) Each bond of the Fifty-Sixth Series may have such other terms as are not inconsistent with Section 2.03 of the Mortgage, and as may be determined by or in accordance with a Resolution filed with the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(VI) At the option of the registered owner, any bonds of the Fifty-Sixth Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series and same terms of other authorized denominations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(VII) Bonds of the Fifty-Sixth Series shall be transferable, subject to any restrictions thereon set forth in any such bond of the Fifty-Sixth Series, upon the surrender thereof for cancellation, together with a written instrument of transfer, if required by the Company, duly executed by the registered owner or by his, her or its duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any transfer or exchange of bonds of the Fifty-Sixth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Fifty-Sixth Series.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(VIII) After the execution and delivery of this Thirty-Sixth Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Thirty-Sixth Supplemental Indenture, it is contemplated that there shall be issued bonds of the Fifty-Sixth Series in an initial aggregate principal amount of Four Hundred Million Dollars (U.S. $400,000,000).

**ARTICLE II**

**Regarding Properties Excepted from Lien of Mortgage**

*SECTION 2.01.* The Company reserves the right, without any consent or other action by holders of bonds of the Ninth Series, or any other series of bonds subsequently created under the Mortgage (including the bonds of the Fifty-Sixth Series), to make such amendments to the Mortgage, as heretofore amended and supplemented, as shall be necessary in order to amend the first proviso to the granting clause of the Mortgage, which proviso sets forth the properties excepted from the Lien of the Mortgage, to add a new exception (10) which shall read as follows:

"(10) allowances allocated to steam-electric generating plants owned by the Company or in which the Company has interests, pursuant to Title IV of the Clean Air Act Amendments of 1990, Pub. L. 101-549, Nov. 15, 1990, 104 Stat. 2399, 42 USC 7651, et seq., as now in effect or as hereafter supplemented or amended."

**ARTICLE III**

**Miscellaneous Provisions**

*SECTION 3.01.* The right, if any, of the Company to assert the defense of usury against a holder or holders of bonds of the Fifty-Sixth Series or any subsequent series shall be determined only under the laws of the State of New York.

The terms defined in Article I of this Thirty-Sixth Supplemental Indenture shall, for purposes of that Article, have the meanings specified in Article I of this Thirty-Sixth Supplemental Indenture.

*SECTION 3.03.* The Trustee hereby accepts the trusts hereby declared, provided, created or supplemented, and agrees to perform the same upon the terms and conditions herein and in the Mortgage, as hereby supplemented, set forth, including the following:

The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Thirty-Sixth Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made by the Company solely. Each and every term and condition contained in Article XIX of the Mortgage shall apply to and form part of this Thirty-Sixth Supplemental Indenture with the same force and effect as if the same were herein set forth in full, with such omissions, variations and insertions, if any, as may be appropriate to make the same conform to the provisions of this Thirty-Sixth Supplemental Indenture.

*SECTION 3.04.* Whenever in this Thirty-Sixth Supplemental Indenture either of the Company or the Trustee is named or referred to, this shall, subject to the provisions of Articles XVIII and XIX of the Mortgage, be deemed to include the successors and assigns of such party, and all the covenants and agreements in this Thirty-Sixth Supplemental Indenture contained by or on behalf of the Company, or by or on behalf of the Trustee, shall, subject as aforesaid, bind and inure to the respective benefits of the respective successors and assigns of such parties, whether so expressed or not.

*SECTION 3.05.* Nothing in this Thirty-Sixth Supplemental Indenture, expressed or implied, is intended, or shall be construed to confer upon, or to give to, any person, firm or corporation, other than the parties hereto and the holders of the bonds and coupons outstanding under the Mortgage, any right, remedy or claim under or by reason of this Thirty-Sixth Supplemental Indenture or any covenant, condition, stipulation, promise or agreement hereof, and all the covenants, conditions, stipulations, promises and agreements in this Thirty-Sixth Supplemental Indenture contained by or on behalf of the Company shall be for the sole and exclusive benefit of the parties hereto, and of the holders of the bonds and of the coupons outstanding under the Mortgage.

*SECTION 3.06.* This Thirty-Sixth Supplemental Indenture shall be executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument.

If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee's understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

"Electronic Means" shall mean the following communications methods: e-mail, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

Notwithstanding any other provision of this Indenture or any Note, where this Supplemental Indenture or any Note provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the depositary (or its designee) pursuant to the standing instructions from the depositary or its designee, including by electronic mail in accordance with accepted practices at the depositary.

PACIFICORP, an Oregon corporation (the "**Company**"), for value received, hereby promises to pay to CEDE & CO. or registered assigns, on March 15, 2029, at the office or agency of the Company in the Borough of Manhattan, The City of New York, the sum of Four Hundred Million Dollars ($400,000,000), 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, and to pay interest thereon from the March 15 or September 15 next preceding the date hereof, or if no interest has been paid on the bonds of this series, from February 6, 2026, at the rate of four and one-quarter per centum (4.250%) per annum, in like coin or currency at such office or agency on February 15 and August 15 in each year (each, an "**Interest Payment Date**"), commencing September 15, 2026, until the principal of this bond shall have been paid or duly provided for; *provided* that the interest so payable on any Interest Payment Date will, subject to certain exceptions set out in the Thirty-Sixth Supplemental Indenture (hereinafter mentioned), be paid to the person in whose name this bond (or any bond previously Outstanding in transfer or exchange for which this bond was issued) is registered on the Record Date next preceding such Interest Payment Date; *provided*, *however*, that interest payable upon maturity or earlier redemption will be payable to the person to whom principal is payable. So long as this bond remains in book-entry only form, the Record Date for each Interest Payment Date will be the close of business on the Business Day before the applicable Interest Payment Date, and, if this bond is not in book-entry only form, the Record Date for each Interest Payment Date will be the close of business on the 1st calendar day of the month in which the applicable Interest Payment Date occurs (whether or not a Business Day).

The amount of interest payable will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any Interest Payment Date is not a Business Day, then payment of the interest payable on that date will be made on the next succeeding day which is a Business Day (and without any additional interest or other payment in respect of any delay), with the same force and effect as if made on such date.

"**Business Day**" means, for purposes of the preceding two paragraphs, a day other than (i) a Saturday or a Sunday, or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. 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,
4.250% Series Due 2029 to be issued under and equally secured by a Mortgage and Deed of Trust (herein, together with any indenture
supplemental thereto, including the Thirty-Sixth Supplemental Indenture dated as of February 1, 2026, the "**Mortgage** "),
dated as of January 9, 1989 executed by the Company to Morgan Guaranty Trust Company of New York, as trustee (The Bank of New York
Mellon Trust Company, N.A., as successor). 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 and the terms and conditions upon which the bonds are, and are to be, secured, the circumstances under which additional
bonds may be issued and the definitions of certain terms hereinafter used.

With the consent of the Company and to the extent permitted by and in the manner provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of bonds then Outstanding under the Mortgage, all voting as a single class or, if the rights of the holders of one or more, but less than all, series of bonds then Outstanding are to be adversely affected, then by affirmative vote of the holders of at least sixty per centum (60%) principal amount of those bonds then Outstanding so to be adversely affected, all voting as a single class (excluding in any case bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); *provided* that no such modification or alteration shall, without the consent of the holder hereof, impair or affect the right of the holder to receive payment of the principal of (and premium, if any) and interest on this bond, on or after the respective due dates expressed herein, or to institute suit for the enforcement of any such payment on or after such respective dates, or permit the creation of and lien ranking equal or prior to the Lien of the Mortgage or deprive the bolder of the benefit of a lien on the Mortgaged and Pledged Property or reduce the percentage vote required to effect such modifications or alterations.

The Company has reserved the right, without any consent or other action by holders of bonds of the Ninth Series known as First Mortgage and Collateral Trust Bonds, Secured Medium-Term Notes, Series F, or any other series of bonds subsequently created under the Mortgage (including the bonds of this series), to amend the Mortgage in order to except from the Lien of the Mortgage allowances allocated to steam-electric generating plants owned by the Company, or in which the Company, or in which the Company has interests, pursuant to Title IV of the Clean Air Act Amendments of 1990 as now in effect or as hereafter supplemented or amended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The principal hereof may be declared or may become due prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a Default as in the Mortgage provided.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Prior to February 15, 2029 (one month prior to their maturity date) (the "**Par Call Date**"), the Company may redeem the bonds at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to (A) the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the bonds matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 10 basis points less (b) interest accrued to the date of redemption, and (ii) one hundred per centum (100%) of the principal amount of bonds of this series then Outstanding to be redeemed; plus (B) accrued and unpaid interest thereon to the date on which such bonds are to be redeemed (the "**Redemption Date**"). On or after the Par Call Date, the redemption price shall be equal to one hundred per centum (100%) of the principal amount of bonds of this series then Outstanding to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

For purposes of this Section 3:

"**Treasury Rate**" means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily) - H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third business day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company's actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee shall have no responsibility for the calculation of the redemption price.

The Company shall give the Trustee notice of the redemption price for any redemption occurring prior to the par call date immediately after the calculation thereof, and the Trustee shall have no responsibility for such calculation.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of bonds to be redeemed at its registered address.

In the case of a partial redemption, selection of the bonds for redemption will be made by lot. No bonds of a principal amount of $2,000 or less will be redeemed in part. If any bond is to be redeemed in part only, the notice of redemption that relates to the bond will state the portion of the principal amount of the bond to be redeemed. A new bond in a principal amount equal to the unredeemed portion of the bond will be issued in the name of the holder of the bond upon surrender for cancellation of the original bond. For so long as the bonds are held by The Depository Trust Company (or another depositary), the redemption of the bonds shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the Redemption Date interest will cease to accrue on the bonds or portions thereof called for redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his, her or its duly authorized attorney, 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, if required by the Company, duly executed by the registered owner or by his, her or 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. Subject to the foregoing provisions as to the person entitled to receive payment of interest hereon, the Company and the Trustee may deem and treat the person in whose name this bond is registered as the holder and the absolute owner hereof for the purpose of receiving payment and for all other purposes, and neither the Company nor the Trustee shall be affected by any notice to the contrary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. 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 fully registered bonds of the same series of other authorized denominations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. As provided in the Mortgage, the Company shall not be required to make transfers or exchanges of bonds of any series for a period of fifteen (15) days next preceding any designation of bonds of such series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds designated in whole or in part for redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. No recourse shall be had for the payment of the principal of, premium, if any, or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, shareholder, 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, shareholders, 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 The Bank of New York Mellon Trust Company, N.A., a national banking association, the Trustee under the Mortgage, or its successor thereunder, shall have signed the form of authentication certificate endorsed hereon.

We have acted as special counsel to PacifiCorp, an Oregon corporation (the "Company"), in connection with the registration under the Securities Act of 1933, as amended (the "Securities Act") and the rules and regulations promulgated thereunder (the "Rules") of $400,000,000 in aggregate principal amount of the Company's 4.250% Series First Mortgage Bonds Due 2029 (the "Bonds") pursuant to a registration statement on Form S-3 (333-281019) (the "Registration Statement") and the prospectus contained therein (the "Prospectus"), dated July 25, 2024, and the supplement to the Prospectus dated February 4, 2026 (the "Prospectus Supplement"). The Bonds will be issued pursuant to the Mortgage and Deed of Trust, dated as of January 9, 1989, between the Company and The Bank of New York Mellon Trust Company, N.A. (the "Trustee"), as successor trustee, as amended and supplemented by the Thirty-Sixth Supplemental Indenture dated as of February 1, 2026 between the Company and the Trustee (the "Supplemental Indenture", and, together with the Mortgage and Deed of Trust, the "Mortgage"), and sold by the Company pursuant to the Underwriting Agreement, dated February 4, 2026, among the Company and Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC, Mizuho Securities USA LLC, PNC Capital Markets LLC, SMBC Nikko Securities America, Inc. and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein (the "Underwriting Agreement").

In our capacity as counsel to the Company, we have examined such documents, records and instruments as we have deemed necessary for the purposes of this opinion. As to matters of fact material to the opinion expressed herein, we have relied on (a) information in public authority documents and (b) information provided in certificates of officers of the Company. All opinions based on the foregoing documents and certificates are as of the date of such documents and certificates, not as of the date of this opinion letter. We have not independently verified the facts so relied on.

In such examination, we have assumed the following without investigation: (a) the authenticity of original documents and the genuineness of all signatures; (b) the conformity to the originals of all documents submitted to us as copies and (c) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed.

Based upon the foregoing examination and in reliance thereon, and subject to (x) the assumptions stated and in reliance on statements of fact contained in the documents that we have examined and (y) completion of all corporate action required to be taken by the Company to duly authorize the proposed issuance of the Bonds, we are of the opinion that, when (a) the terms of the Bonds have been established in accordance with the Mortgage, (b) the applicable supplement to the Mortgage has been duly authorized and validly executed and delivered by the Company and the trustee thereunder and (c) the Bonds have been executed and authenticated in accordance with the terms of the Mortgage, and the applicable supplement thereto, and issued and delivered in accordance with the terms of the Underwriting Agreement against payment of the consideration set forth therein and as contemplated by the Registration Statement and the Prospectus Supplement, the Bonds will constitute binding obligations of the Company.

The foregoing opinion is subject to the following exclusions and qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Our opinion is as of the date hereof, and we have no responsibility to update this opinion for events and circumstances occurring after the date hereof or as to facts relating to prior events that are subsequently brought to our attention. This opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, and we disavow any undertaking to advise you of any changes in law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) We express no opinion as to enforceability of any right or obligation to the extent such right or obligation is subject to and limited by (i) the effect of bankruptcy, insolvency, reorganization, receivership, conservatorship, arrangement, moratorium, fraudulent transfer or other laws affecting or relating to the rights of creditors generally; (ii) rules governing the availability of specific performance, injunctive relief or other equitable remedies and general principles of equity, regardless of whether arising prior to or after the date hereof or considered in a proceeding in equity or at law; or (iii) the effect of federal and state securities laws and principles of public policy on the rights of indemnity and contribution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) We express no opinion concerning any laws other than the laws in their current forms of the State of Oregon and the State of New York, and we express no opinion with respect to the laws of any other jurisdiction and expressly disclaim responsibility for advising you as to the effect, if any, that the laws of any other jurisdiction may have on the opinion set forth herein.

We hereby consent to the filing of this opinion as an exhibit to the Company's Report on Form 8-K filed with the Securities and Exchange Commission on or about the date hereof, to the incorporation by reference of this opinion into the Registration Statement and any amendments thereto, including any and all post-effective amendments, and to the reference to our firm in the Prospectus Supplement under the heading "Legal Matters." In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or related Rules.
