Dear Sirs:

1. Introductory. PacifiCorp, an Oregon corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to ▇▇▇▇▇▇▇, Sachs & Co. and BNP Paribas Securities Corp. (the “Underwriters”) U.S. $600,000,000 principal amount of its First Mortgage Bonds, 5.75% Series due 2037 (the “Offered Securities”) to be issued under that certain Mortgage Deed and Trust, dated as of January 9, 1989, with The Bank of New York, 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 March 1, 2007 (collectively, the “Mortgage”) pursuant to registration statements on Form S-3 (File No. 333-128134 and 333-140661) filed on February 13, 2007, as amended to date (collectively the “Initial Registration Statement”). The Mortgage has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Trust Indenture Act. The United States 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:

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

(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, 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, has been declared effective by the Commission in such form;

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, and 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 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.

(b) A preliminary prospectus and a final prospectus relating to the Offered Securities to be offered by the Underwriters have been prepared by the Company. Such preliminary prospectus (including the documents incorporated by reference therein) is hereinafter referred to as, the “Preliminary Prospectus”; such form of final prospectus relating to the Offered Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act (including the documents incorporated by reference therein) 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 of the Closing Date (as defined below), did not and will 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; and each Issuer Free Writing Prospectus (as defined in Rule 433 under the Securities Act) listed on Schedule B(ii) hereto does not conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus and each such Issuer Free Writing Prospectus, 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 or any Issuer Free Writing Prospectus 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 1:03 p.m., New York City Time, on the date of this Agreement.

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 Act) of the Offered Securities, the Company was not an “ineligible issuer” as defined in Rule 405 under the Securities Act.

(c) 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 does 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, and the Prospectus as of its date as amended or supplemented as of the Closing Date does 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, in the light of the circumstances under which they were made, not misleading.

(d) 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”).

(e) The Mortgage has been duly authorized, executed and delivered by the Company, and constitutes 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.

(f) 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.

(g) 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.

(h) 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.

(i) Except as disclosed in the Disclosure Package and the Prospectus, the Company has good and sufficient title to all the properties described as owned or 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.

(j) The Company is not in violation of (i) the Articles of Incorporation (the “Articles”) or its Bylaws, as amended, or 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 (ii) 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), 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.

(k) 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 which are not adequately disclosed in the Disclosure Package and the Prospectus 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.

(l) 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 PricewaterhouseCoopers LLP, who examined certain audited financial statements of the Company, was, as of May 26, 2006 and during the period covered by the financial statements on which they reported, an independent registered public accounting firm as required by the Securities Act and the Rules and Regulations thereunder; 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 Act and the Regulations thereunder.

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.

(n) The Company (i) makes and keeps books, records, and accounts, which, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company and its consolidated subsidiaries and (ii) maintains a system of internal accounting controls sufficient to provide reasonable assurances that (1) transactions are executed in accordance with management’s general or specific authorization; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles or any other criteria applicable to such statements and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management’s general or specific authorization; and (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(d) Subsequent to the Applicable Time, there shall not have been (i) any change, or any development or event involving a prospective change, in the financial condition, business, properties or results of operations of the Company and its subsidiaries taken as a whole, which, in the judgment of the Underwriters, is material and adverse and makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities or preferred stock of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange; (iv) any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of

In rendering such opinion, ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP may rely as to the incorporation of the Company and all other matters governed by Oregon law upon the opinion of ▇▇▇▇ ▇. ▇▇▇▇▇▇ referred to above.

(h) The Underwriters shall have received a certificate, dated the Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers, to the best of their knowledge after reasonable investigation, shall state that: (i) the representations and warranties of the Company in this Agreement are true and correct, or true and correct in all material respects where such representations and warranties are not qualified by materiality or Material Adverse Effect; (ii) that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and (iii) that, subsequent to the date of the most recent financial statements in, or incorporated by reference in, the Preliminary Prospectus, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the financial condition, business or results of operations of the Company and its subsidiaries taken as a whole except as set forth in the Disclosure Package and the Prospectus or as described in such certificate.

The Company will (i) furnish the Underwriters with such conformed copies of such opinions, certificates, letters and documents as the Underwriters reasonably request. The Underwriters may waive compliance with any conditions to their obligations hereunder.

A. The Company (i) represents and agrees that, other than the final term sheet prepared and filed pursuant to Section 5(a) hereof, without the prior consent of the Underwriters, it has not made and will not make any offer relating to the Offered Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Act and (ii) has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending.

B. each Underwriter represents and agrees that, without the prior consent of the Company and the Underwriters, other than one or more term sheets relating to the Offered Securities containing customary information, it has not made and will not make any offer relating to the Offered Securities that would constitute a free writing prospectus; and

C. any such free writing prospectus the use of which has been consented to by the Company and the Underwriters (including the final term sheet prepared and filed pursuant to Section 5(a) hereof) is listed on Schedule B hereto;

7. Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter 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 or any Issuer Free Writing Prospectus, or any amendment or supplement to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein made, in 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, including 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, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriters specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below; provided, further, that the foregoing indemnity with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities (or actions in respect thereof), in connection with clauses (i) through (iii) below, purchased Offered Securities, or any person controlling such Underwriter, where it shall have been determined by a court of competent jurisdiction by final and non-appealable judgment that (i) prior to the Applicable Time the Company has notified such Underwriter that the Preliminary Prospectus, dated March 9, 2007, contains an untrue statement of material fact or omits 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, not misleading, (ii) such untrue statement or omission of a material fact was corrected in an amended or supplemented Preliminary Prospectus and such corrected Preliminary Prospectus was provided to such Underwriter sufficiently in advance of the Applicable Time so that such corrected Preliminary Prospectus could have been conveyed to such person prior to the Applicable Time and (iii) such corrected Preliminary Prospectus was not conveyed to such person at or prior to the Applicable Time to such person.

(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 or any Issuer Free Writing Prospectus, or any amendment or supplement to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus or 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 such Underwriter 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”, paragraphs 3, 4 (second sentence only) 5 and 6; 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.

(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 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.

(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 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 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.

(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.

8. Default of Underwriters. If any Underwriter or Underwriters defaults in its or their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of 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 the 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 Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of 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 a 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.

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 the termination of this Agreement pursuant to Section 8 or 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 out-of-pocket expenses (including fees and disbursements of counsel) reasonably 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.

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 Bonds; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company in connection with the offering of the Bonds 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; any duties and obligations that the Underwriters may have to the Company in connection with the offering of the Bonds 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.

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) ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention Registration Department, and (ii) BNP Paribas Securities Corp., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇.▇. ▇▇▇▇▇, Facsimile number ▇▇▇-▇▇▇-▇▇▇▇, Attention: Debt Capital Markets, with a copy to Legal Capital Markets, Facsimile number ▇▇▇-▇▇▇-▇▇▇▇, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at PacifiCorp, ▇▇▇ ▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Legal Department; provided, however, that any notice to a Underwriter pursuant to Section 7 will be mailed, delivered or faxed and confirmed to such Underwriter.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

13. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

14. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws.
