Ladies and Gentlemen:

Puget Sound Energy, Inc., a Washington corporation (the “Company”), confirms its agreement with ▇▇▇▇▇▇ Brothers Inc., ▇.▇. ▇▇▇▇▇▇ Securities Inc. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co.

The Securities are to be issued as a separate series of notes under the Indenture, dated as of May 18, 2001, between the Company and The Bank of New York Trust Company, N.A. (as successor to Bank One Trust Company, N.A.), as trustee (the “Trustee”) (the “Base Indenture”, as supplemented by the Second Supplemental Indenture to be dated as of June 1, 2007, (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”). Capitalized terms used herein without definition shall be used as defined in the Prospectus (as hereinafter defined).

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deems advisable after this Agreement has been executed and delivered and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”).

The Company, together with its parent, Puget Energy, Inc., has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement, as defined in Rule 405 (“Rule 405”) of the rules and regulations (the “1933 Act Regulations”) of the Commission under the Securities Act of 1933, as amended (the “1933 Act”), on Form S-3 (No. 333-132497-01), including a related Base Prospectus contained therein (the “Base Prospectus”), covering the registration of the Securities under the 1933 Act. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus (which term, as used herein, shall include the Final Preliminary Prospectus), or the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be. All references herein to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended, (the “1934 Act”) on or before the Effective Date of the Registration Statement or the issue date of, any preliminary prospectus or the Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the filing of any document under the 1934 Act after the Effective Date of the Registration Statement or the issue date of any preliminary prospectus or the Prospectus, as the case may be, deemed to be incorporated therein by reference.

Certain terms used herein are defined in Section 20 hereof.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof and as of the Closing Time referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(i) Compliance with Registration Requirements.

(A) The Company meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement became effective upon filing and any post-effective amendment thereto has become effective under the 1933 Act. No stop order suspending the effectiveness, or any written or oral notice to the Company objecting to the use, of the Registration Statement

or any post-effective amendment thereto has been issued by the Commission under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Securities, each of which has previously been furnished to you. The Company will file with the Commission a final prospectus supplement relating to the Securities in accordance with the provisions of paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. As filed, such final prospectus supplement shall contain all information required by the 1933 Act and the 1933 Act Regulations, and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any preliminary prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x).

(B) On each Effective Date, the Registration Statement did, and when the Prospectus is first filed in accordance with Rule 424(b) and at the Closing Time (as defined herein), the Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the 1933 Act and the 1933 Act Regulations, the 1934 Act and the and the rules and regulations of the Commission under the 1934 Act (the “1934 Act Regulations”) and the 1939 Act and the rules and regulations of the Commission under the 1939 Act (the “1939 Act Regulations”); on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; on each Effective Date and at the Closing Time the Indenture did and will comply in all material respects with the applicable requirements of the 1939 Act and the rules thereunder; and on the date of any filing pursuant to Rule 424(b) and at the Closing Time, the Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties in this subsection shall not apply (x) to statements in or omissions from the Registration Statement or Prospectus made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or in the Prospectus (or any amendment or supplement thereto) or (y) to that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) under the 1939 Act of the Trustee.

(C) (i) the Disclosure Package and (ii) each, if any, electronic roadshow when taken as a whole with the Disclosure Package, at the Applicable Time do not contain any untrue statement of a material fact or omit to state any material fact

necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package or any electronic roadshow based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein.

(D) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the 1934 Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of section (c) of Rule 163 (“Rule 163”) of the 1933 Act Regulations) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)) the Company was or is (as the case may be) a Well-Known Seasoned Issuer. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations.

(E) (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) (“Rule 164(h)(2)”) of the 1933 Act Regulations) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)) the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

(F) Each issuer free writing prospectus, as defined in Rule 433 (“Rule 433”) of the 1933 Act Regulations (each an “Issuer Free Writing Prospectus”), including the final term sheet prepared and filed pursuant to Section 3(b) hereto, does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. Each Issuer Free Writing Prospectus, when taken as a whole with the Disclosure Package, at the Applicable Time does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein.

(ii) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and 1934 Act Regulations.

(iii) Independent Registered Public Accounting Firm. PricewaterhouseCoopers LLP, which has certified the financial statements and supporting schedules filed with the Commission and incorporated by reference in the Registration Statement, and which has audited the Company’s internal control over financial reporting and management’s assessment thereof, is an independent public accounting firm as required by the 1933 Act and the 1933 Act Regulations and to the best of our knowledge, is registered as such.

(iv) Financial Statements. The financial statements included in the Registration Statement, any preliminary prospectus and the Prospectus, together with the related schedules and notes, present fairly the financial position of the Company and its consolidated subsidiaries at the dates indicated and the statement of operations, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; said financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved. The supporting schedules, if any, included in the Registration Statement, any preliminary prospectus and the Prospectus present fairly in accordance with GAAP the information required to be stated therein. The selected financial data and the summary financial information, if any, included in the Registration Statement, any preliminary prospectus and the Prospectus present fairly the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement. Any pro forma financial statements and the related notes thereto included in the Registration Statement, any preliminary prospectus and the Prospectus present fairly the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.

(v) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Registration Statement, the Disclosure Package and the Prospectus, except as otherwise stated in the Disclosure Package and the Prospectus, (A) there has been no material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (a “Material Adverse Effect”), (B) there have been no transactions entered into by the Company or any of its subsidiaries, other than those in the ordinary course of business, which are material with respect to the Company and its subsidiaries considered as one enterprise, and (C) except for regular quarterly dividends on the common stock, par value $10.00 per share, of the Company (the “Common Stock”) and on the preferred stock, par value $100 per share, of the Company in amounts per share that are consistent with past practice, there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its capital stock.

The Company has been duly organized and is validly existing as a corporation under the laws of the State of Washington and has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus and to enter into and perform its obligations under this Agreement; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

The Indenture has been duly authorized by the Company and duly qualified under the 1939 Act and, when duly executed and delivered by the Company, and assuming due execution by the Trustee, will constitute a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(x) Authorization of the Securities. The Securities have been duly authorized and, at the Closing Time, will have been duly executed by the Company and, when authenticated, issued and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in this Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and will be in the form contemplated by, and entitled to the benefits of, the Indenture.

(xi) Description of the Securities and the Indenture. The Securities, the Replacement Capital Covenant to be entered into by the Company at or around the Closing Time (the “Replacement Capital Covenant”) and the Indenture will conform in all material respects to the respective statements relating thereto contained in the Registration Statement, the Disclosure Package and the Prospectus and will be in substantially the respective forms filed or incorporated by reference, as the case may be, as exhibits to the Registration Statement.

All descriptions in the Registration Statement, any preliminary prospectus relating to the offering of the Securities, the Disclosure Package and the Prospectus of contracts and other documents to which the Company or its subsidiaries are a party are accurate in all material respects; there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement, any preliminary prospectus relating to the offering of the Securities, the Prospectus, or to be filed as exhibits thereto other than those described or referred to therein or filed or incorporated by reference as exhibits thereto.

(xvi) Absence of Manipulation.

all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect; all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, result in a Material Adverse Effect; and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect.

During the period when the Prospectus is required to be delivered under the 1933 Act in connection with the offer and sale of the Securities (including in circumstances where such requirement may be satisfied pursuant to Rule 172 (“Rule 172”) of the 1933 Act Regulations), the Company, subject to Section 3(c), will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or for additional information, and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, the Disclosure Package or the Prospectus or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection by the Commission to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) Final Term Sheet. The Company will prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof, in a form approved by you and attached as Exhibit B hereto and will timely file such term sheet pursuant to Rule 433(d) of the 1933 Act Regulations.

(c) Disclosure Package. If, at any time prior to the filing of the Prospectus, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(d) Filing of Amendments. During the period when the Prospectus is required to be delivered under the 1933 Act in connection with the offer and sale of the Securities (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(e) Delivery of Registration Statements. The Company has furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(f) Delivery of Prospectuses. The Company has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), such number of copies of each preliminary prospectus, any Issuer Free Writing Prospectus and the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(g) Free Writing Prospectuses. The Company agrees that unless it has obtained or will obtain the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than the information contained in the final term sheet prepared and filed pursuant to Section 3(b) hereto; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses identified in

Schedule C hereto. The Company agrees that it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Issuer Free Writing Prospectus, including in respect to timely filing with the Commission, legending and recordkeeping.

(h) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations and the 1939 Act and the 1939 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement, the Disclosure Package and the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus or Registration Statement will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading (in the case of the Propsectus, in the light of the circumstances existing at the time it is delivered to a purchaser), or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or file a new registration statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, including in connection with use or delivery of the Prospectus, the Company will (i) notify the Representatives of such event, (ii) promptly prepare and file with the Commission, subject to Section 3(d), such amendment or supplement or new registration statement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in the use of the Prospectus and (iv) furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(i) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions as the Representatives may designate; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Securities for investment under the laws of such jurisdictions as the Underwriters may reasonably request.

(j) Rule 158. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(k) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Prospectus under “Use of Proceeds.”

(l) Restriction on Sale of Securities. Other than the existing 37,750 outstanding shares of 8.231% trust preferred securities and the Company’s 8.231% Junior Subordinated Deferrable Interest Debentures due 2027, both of which are to be redeemed on June 1, 2007, during a period of 14 calendar days after the date of the Prospectus, the Company will not, without the prior written consent of the Representatives directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise transfer or dispose of, any similar term debt securities of the Company substantially similar to the Securities.

(m) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(n) Replacement Capital Covenant. The Replacement Capital Covenant will be executed by the Company at or before the Closing Time.

The obligations of the several Underwriters hereunder are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof or in certificates of any officer of the Company or any subsidiary of the Company delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder, and to the following further conditions:

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York and the federal law of the United States, upon the opinions of counsel satisfactory to the Representatives. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials.

(i) Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Company at any time at or prior to the Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) of the 1933 Act Regulations (each, an “Affiliate”), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any director, officer or employee thereof as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any preliminary prospectus or any other preliminary prospectus supplement relating to the Securities, the Prospectus, any Issuer Free Writing Prospectus, the Disclosure Package, or in any amendment thereof or supplement thereto, or the omission or alleged omission therefrom of 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) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives, reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or in the Base Prospectus, any preliminary prospectus or any other preliminary prospectus supplement relating to the Securities, the Prospectus, any Issuer Free Writing Prospectus, the Disclosure Package, or in any amendment thereof or supplement thereto.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or in the Base Prospectus, any preliminary prospectus or any other preliminary prospectus supplement relating to the Securities, the Prospectus, any Issuer Free Writing Prospectus, the Disclosure Package, or in any amendment thereof or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received

notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (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 hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, 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 hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, each Underwriter’s Affiliates and selling agents, and any director, officer or employee thereof, shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Company, and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus (exclusive of any supplement thereto), any material adverse change not contemplated by the Prospectus (as it exists on the date hereof) in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, which, in your judgment, materially impairs the investment quality of the Securities or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the reasonable judgment of the Representatives, impracticable or inadvisable to offer, sell or deliver the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange (“NYSE”), or if trading generally has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by said exchange or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (v) if a banking moratorium has been declared by Federal, New York or Washington authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(1) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(2) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 5(b)

(i) The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Washington.

(ii) The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and the Disclosure Package and to enter into and perform its obligations under the Purchase Agreement.

(iii) The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(iv) The Purchase Agreement has been duly authorized, executed and delivered by the Company.

(v) The Indenture has been duly authorized, executed and delivered by the Company and (assuming the due authorization, execution and delivery thereof by the Trustee) constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(vi) The Securities are in the form contemplated by the Indenture, have been duly authorized by the Company for offer, sale, issuance and delivery, have been duly executed by the Company and, when issued and authenticated in the manner provided for in the Indenture and delivered against payment of the consideration therefor will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and except as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and will be entitled to the benefits of the Indenture.

(vii) The Indenture has been duly qualified under the 1939 Act.

A-1

(viii) The Securities, the Indenture and the Replacement Capital Covenant conform as to legal matters in all material respects to the descriptions thereof contained in the Registration Statement, the Prospectus and the Disclosure Package.

(ix) The Registration Statement has become effective under the 1933 Act; any required filing of any preliminary prospectus and of the Prospectus and any supplements thereto pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); and, to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement or any written or oral notice to the Company objecting to the use of the Registration Statement or any post-effective amendment thereto has been issued by the Commission under the 1933 Act and to the best of our knowledge no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

(x) The Registration Statement, the Prospectus, excluding the documents incorporated by reference therein, and each amendment or supplement to the Registration Statement and Prospectus, excluding the documents incorporated by reference therein, as of their respective effective or issue dates (other than the financial statements and supporting schedules included therein or omitted therefrom, and the Trustee’s Statement of Eligibility on Form T-1 (the “Form T-1”), as to which we need express no opinion) complied as to form in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.

(xi) The documents incorporated by reference in the Registration Statement, the Final Preliminary Prospectus and the Prospectus (other than the financial statements and supporting schedules included therein or omitted therefrom, as to which we need express no opinion), when they were filed with the Commission, complied as to form in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission thereunder.

(xii) Except as disclosed in the Final Preliminary Prospectus and the Prospectus, to the best of our knowledge, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any subsidiary is a party, or to which the property of the Company or any subsidiary is subject, before or brought by any court or governmental agency or body, domestic or foreign, which would reasonably be expected to result in a Material Adverse Effect, or which would reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Purchase Agreement or the performance by the Company of its obligations thereunder, or under the terms of the Indenture or the Securities.

(xiii) The information in any preliminary prospectus and in the Prospectus under “Description of Securities,” or any caption purporting to cover such matters, in the Registration Statement under Item 15 and, to our knowledge, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006 under “Regulation and Rates” and “Legal Proceedings,” to the extent that it constitutes matters of law, summaries of legal matters, the Company’s charter and bylaws or legal proceedings, or legal conclusions, has been reviewed by us and is correct in all material respects.

(xiv) The statements in any preliminary prospectus and in the Prospectus under “Certain U.S. Federal Income Tax Considerations,” to the extent that they constitute summaries of matters of United States federal income tax law or legal conclusions with respect thereto, has been reviewed by us and constitute accurate summaries of the matters discussed therein in all material respects.

A-2

(xv) All descriptions in the Registration Statement, any preliminary prospectus, the Disclosure Package and the Prospectus of contracts and other documents to which the Company or its subsidiaries are a party are accurate in all material respects; to the best of our knowledge, there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement, the Disclosure Package, any preliminary prospectus or the Prospectus or to be filed as exhibits to the Registration Statement other than those described or referred to therein or filed or incorporated by reference as exhibits thereto.

(xvi) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign is necessary or required in connection with the due authorization, execution and delivery of the Purchase Agreement or the due execution, delivery or performance of the Indenture by the Company or for the offering, issuance, sale or delivery of the Securities, other than (a) such filings subsequent to the date hereof as may be required by the Utilities Commission or under Section 80.08.040 of the Revised Code of Washington, (b) under the 1933 Act and the 1933 Act Regulations, which have been obtained, or as may be required under the securities or blue sky laws of the various states and (c) qualification of the Indenture under the 1939 Act, as to which we need express no opinion.

(xvii) The execution, delivery and performance of the Purchase Agreement, the Indenture and the Securities and the consummation of the transactions contemplated in the Purchase Agreement and in the Registration Statement, the Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in any preliminary prospectus and the Prospectus under the caption “Use Of Proceeds”) and compliance by the Company with its obligations under the Purchase Agreement, the Indenture and the Securities do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined in Section 1(a)(xii) of the Purchase Agreement) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary pursuant to any contract or any other agreement or instrument listed as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2006 (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its properties, assets or operations.

(xviii) The Company is not required, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Disclosure Package and the Prospectus will not be an “investment company” or a company “controlled” by an “investment company” which is required to be registered under the 1940 Act.

A-3

(xix) To the best of our knowledge, there are no statutes or regulations that are required to be described in the Disclosure Package or the Prospectus that are not described as required.

(xx) To the best of our knowledge, (A) the Company is not in violation of its charter or bylaws, and (B) no default by the Company exists in the due performance or observance of any obligation, agreement, covenant or condition contained in any agreement providing for the issuance of the Company’s securities or under which the Company has outstanding indebtedness for borrowed money, except for such defaults which would not reasonably be expected to have a Material Adverse Effect.

Although we assume no responsibility for the factual accuracy, completeness or fairness of any statements made in the Registration Statement or any amendment thereto or the Prospectus or any amendment or supplement thereto, except as stated in paragraphs (viii), (xiii) and (xiv), nothing has come to our attention that would lead us to believe that on each Effective Date the Registration Statement or any amendment thereto, (except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom and the Form T-1, as to which we need make no statement), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus or any amendment or supplement thereto (except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom and the Form T-1, as to which we need make no statement), at the time the Prospectus was issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or that the Disclosure Package at the Applicable Time included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
