Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Prospectus. The Company hereby undertakes to provide, without charge, to each person to whom a copy of this Prospectus shall have been delivered, upon written or oral request of such person, a copy of any or all of the documents which have been incorporated in this Prospectus by reference, other than exhibits to such documents, unless such exhibits shall have been specifically incorporated by reference into such documents. Requests for such copies should be directed to C.J. Rue, Secretary, Northwest Natural Gas Company, One Pacific Square, 220 N.W. Second Avenue, Portland, Oregon 97209, telephone 503-226-4211. THE COMPANY The Company's executive offices are located at One Pacific Square, 220 N.W. Second Avenue, Portland, Oregon 97209. Its telephone number is 503-226-4211. The Company and its predecessors have supplied gas service to the public since 1859. The Company is principally engaged in the distribution of natural gas to customers in western Oregon and southwestern Washington, including the Portland metropolitan area. USE OF PROCEEDS AND FINANCING PROGRAM The net proceeds to be received by the Company from the sale of the Medium-Term Notes will be added to the general funds of the Company and used for corporate purposes, primarily to fund, in part, the Company's ongoing utility construction program. The Company expects its utility construction expenditures in 1997 to aggregate $110 million, and in the five-year period, 1997-2001, to aggregate between $500 million and $550 million. It is estimated that 50% of the funds required for utility purposes during the 1997-2001 period will be internally generated and that the balance, as well as substantially all of the funds required for the refunding of maturing and higher-cost debt, will be raised through the sale of equity and debt securities, including the Medium-Term Notes, in such amounts and at such times as the Company's cash requirements and market conditions shall determine. Approximately $25 million, $15 million and $10 million of debt securities will mature in 1997, 1998 and 1999, respectively. 2 RATIO OF EARNINGS TO FIXED CHARGES The ratios of earnings to fixed charges, calculated according to the rules set forth under the Securities Act of 1933, as amended, for the following twelve-month periods were: TWELVE MONTHS ENDED ----------------------------------------------------------------- DECEMBER 31, ----------------------------------------------------------------- 1996 1995 1994 1993 1992 ----------------------------------------------------------------- 3.53 3.15 3.08 3.22 1.81 Earnings consist of net income to which has been added taxes on income and fixed charges. Fixed charges consist of interest on all indebtedness, amortization of debt expense and discount or premium, and the estimated interest portion of rentals charged to income. BOOK-ENTRY SYSTEM DTC will act as securities depository for the Medium-Term Notes of each issue. Except under the circumstances described below, the Medium-Term Notes will be issued in the form of one or more fully registered notes that will be deposited with, or on behalf of, DTC or such other depository as may be subsequently designated ("Depository"), and registered in the name of CEDE & Co. (DTC's partnership nominee), or such other Depository or its nominee as may be subsequently designated. So long as the Depository, or its nominee, is the registered owner of the Medium-Term Notes, such Depository or such nominee, as the case may be, will be considered the owner of such Medium-Term Notes for all purposes under the Mortgage or the Indenture (each as defined below), as the case may be, including notices and voting. Payments of principal of, and premium, if any, and interest on, the Medium-Term Notes will be made to the Depository or its nominee, as the case may be, as the registered owner of such Medium-Term Notes. Except as set forth below, owners of beneficial interests in Medium-Term Notes will not be entitled to have any individual Medium-Term Notes registered in their names, will not receive or be entitled to receive physical delivery of any such Medium-Term Notes and will not be considered the owners of Medium-Term Notes under the Mortgage or the Indenture. Accordingly, each person holding a beneficial interest in a Medium-Term Note must rely on the procedures of the Depository and, if such person is not a Direct Participant (as hereinafter defined), on procedures of the Direct Participant through which such person holds its interest, to exercise any of the rights of the registered owner of such Medium-Term Note. If the Depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed by the Company, individual registered Medium-Term Notes will be issued in exchange for the Medium-Term Notes held by the Depository. In addition, the Company, at any time and in its sole discretion, may determine not to have the Medium-Term Notes held by the Depository and, in such event, individual registered Medium-Term Notes will be issued in exchange for the Medium-Term Notes held by the Depository. In any such instance, an owner of a beneficial interest in the Medium-Term Notes will be entitled to physical delivery of individual Medium-Term Notes equal in principal amount to such beneficial interest and to have such Medium-Term Notes registered in its name. Individual Medium-Term Notes so issued will be issued as registered Medium-Term Notes in denominations of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. The following is based solely on information furnished by DTC: DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants ("Participants") deposit with DTC. DTC also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants' accounts, thereby eliminating the need for physical movement of securities certificates. 3 Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations ("Direct Participants"). DTC is owned by a number of its Direct Participants and by The New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as securities brokers and dealers, banks, and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). The rules applicable to DTC and its Participants are on file with the Commission. Purchases of the Medium-Term Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Medium-Term Notes on DTC's records. The ownership interest of each actual purchaser of each Medium-Term Note ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmation providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Medium-Term Notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Medium-Term Notes, except in the event that use of the book-entry system for the Medium-Term Notes is discontinued. To facilitate subsequent transfers, all Medium-Term Notes deposited by Participants with DTC are registered in the name of CEDE & Co. The deposit of Medium-Term Notes with DTC and their registration in the name of CEDE & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Medium-Term Notes; DTC's records reflect only the identity of the Direct Participants to whose accounts such Medium-Term Notes are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. If the Medium-Term Notes of any issue are redeemable prior to the maturity date, redemption notices shall be sent to CEDE & Co. If less than all of the Medium-Term Notes of any issue are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed. Neither DTC nor CEDE & Co. will consent or vote with respect to the Medium-Term Notes. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as possible after the record date. The Omnibus Proxy assigns CEDE & Co.'s consenting or voting rights to those Direct Participants to whose accounts the Medium-Term Notes are credited on the record date (identified in a listing attached to the Omnibus Proxy). Principal and interest payments on the Medium-Term Notes will be made to DTC. DTC's practice is to credit Direct Participants' accounts on the date on which interest is payable in accordance with their respective holdings shown on DTC's records, unless DTC has reason to believe that it will not receive payment on such payment date. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of such Participant and not of DTC, the Mortgage Trustees (as defined below), the Indenture Trustee (as defined below) or the Company, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal and interest to DTC is the responsibility of the Company and the Corporate Trustee (as defined below) or the Indenture Trustee, as the case may be. Disbursement of such payments to Direct Participants shall be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants. DTC may discontinue providing services as securities depository with respect to the Medium-Term Notes at any time by giving reasonable notice to the Company, the Mortgage Trustees and the Indenture Trustee. ---------------- None of the Company or the Mortgage Trustees or the Indenture Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in the Medium-Term Notes or for maintaining, supervising or reviewing any records relating to such beneficial interests. 4 DESCRIPTION OF THE SECURED NOTES GENERAL The Secured Notes, which comprise a series of the Company's First Mortgage Bonds ("Bonds"), are to be issued under the Company's Mortgage and Deed of Trust, dated as of July 1, 1946, to Bankers Trust Company ("Corporate Trustee") and R.G. Page (Stanley Burg, successor), as trustees ("Mortgage Trustees"), as supplemented by twenty supplemental indentures, all of which are collectively referred to as the "Mortgage". The statements herein concerning the Secured Notes and the Mortgage are merely an outline and do not purport to be complete. They make use of terms defined in the Mortgage and are qualified in their entirety by express reference to the cited Sections and Articles. They may be changed with respect to any Secured Note by the applicable Pricing Supplement, which should be read in conjunction with this description. The Secured Notes will be offered on a continuing basis and each Secured Note will mature on such date, not less than nine months or more than 30 years from its date of issue, as selected by the purchaser and agreed to by the Company. The Pricing Supplement relating to each Secured Note will set forth the principal amount, interest rate, issue price and Agent's commission, original issue and maturity dates, redemption provisions, if any, and other material terms of such Secured Note. INTEREST Interest on each Secured Note will be payable semi-annually in arrears on June 1 and December 1 of each year and at maturity. Interest payable on any interest payment date for any Secured Note will be payable to the person in whose name such Secured Note is registered on the record date with respect to such interest payment date, which shall be the May 15 or November 15 (whether or not a business day), as the case may be, next preceding such interest payment date; provided that, (i) if the original issue date of any Secured Note is after a record date and before the corresponding interest payment date, such Secured Note shall bear interest from the original issue date, but payment of interest shall commence on the second interest payment date succeeding the original issue date, and (ii) interest payable on the maturity date will be payable to the person to whom the principal thereof shall be payable. Unless otherwise indicated in the applicable Pricing Supplement, interest on the Secured Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. FORM, EXCHANGE AND PAYMENT The Secured Notes will be issued in fully registered form in denominations of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. The Secured Notes will be exchangeable at the office of Bankers Trust Company in New York City, without charge other than taxes or other governmental charges incident thereto. Principal, premium, if any, and interest will be payable at such office. (See Twentieth Supplemental, Sec. 1.01.) Notwithstanding the foregoing, for so long as the Secured Notes shall be held by the Depository or its nominee, owners of beneficial interests in the Secured Notes will not be entitled to have any individual Secured Notes registered in their names, and transfers of beneficial interests and payments of principal, premium, if any, and interest will be made as described herein under "Book-Entry System". REDEMPTION To the extent, if any, provided in the Pricing Supplement relating to any Secured Note, such Secured Note will be redeemable, on 30 days' notice, in whole or in part, at any time on or after the initial redemption date, if any, fixed at the time of sale and set forth in the applicable Pricing Supplement. On or after the initial redemption date, such Secured Note will be redeemable in whole or in part, at the option of the Company at a redemption price determined in accordance with the following paragraph, plus accrued interest to the date fixed for redemption. The redemption price for each Secured Note subject to redemption shall, for the twelve-month period commencing on the initial redemption date, be equal to a certain percentage of the principal amount of such Secured Note and thereafter, shall decline for the twelve-month period commencing on each anniversary of the initial redemption date by a percentage of 5 principal amount ("Reduction Percentage") until the redemption price shall be 100% of the principal amount. The initial redemption date and price and any Reduction Percentage with respect to each Secured Note subject to redemption will be fixed at the time of sale and set forth in the applicable Pricing Supplement. If so specified in the Pricing Supplement relating to any Secured Note, the Company may not, prior to the redemption limitation date, if any, set forth in such Pricing Supplement, redeem such Secured Note as contemplated above as a part of, or in anticipation of, any refunding operation by the application, directly or indirectly, of moneys borrowed having an effective interest cost to the Company (calculated in accordance with generally accepted financial practice) of less than the effective interest cost to the Company (similarly calculated) of such Secured Note. If, at the time the notice of redemption shall be given, the redemption money shall not be on deposit with the Corporate Trustee, the redemption may be made subject to the receipt of such money before the date fixed for redemption, and such notice shall be of no effect unless such money shall be so received. Unless otherwise indicated in the applicable Pricing Supplement, the Secured Notes will not be subject to any sinking fund. PROVISIONS FOR MAINTENANCE OF PROPERTY While the Mortgage contains provisions for the maintenance of the Mortgaged and Pledged Property, the Mortgage does not permit redemption of Bonds pursuant to these provisions. SECURITY The Secured Notes together with all other Bonds now or hereafter issued under the Mortgage will be secured by the Mortgage, which constitutes, in the opinion of Bruce B. Samson, Esq., General Counsel of the Company, a first mortgage lien on all of the gas plants, distribution systems and other materially important physical properties of the Company (except as stated below), subject to (a) leases of minor portions of the Company's property to others for uses which, in the opinion of such Counsel, do not interfere with the Company's business, (b) leases of certain property of the Company not used in its gas utility business or the gas by-product business, (c) excepted encumbrances, and (d) minor defects and encumbrances customarily found in properties of like size and character which, in the opinion of such Counsel, do not impair the use of such properties by the Company. There are excepted from the lien all cash and securities; certain equipment, apparatus, materials or supplies; aircraft, automobiles and other vehicles; receivables, contracts, leases and operating agreements; timber, minerals, mineral rights and royalties; and all natural gas and oil production property. The Mortgage contains provisions subjecting after-acquired property (subject to pre-existing liens) to the lien thereof, subject to limitations in the case of consolidation, merger or sale of substantially all of the Company's assets. (See Mortgage, Art. XVI.) The Mortgage provides that the Mortgage Trustees shall have a lien upon the mortgaged property, prior to that of the Bonds, for the payment of their reasonable compensation and expenses and for indemnity against certain liabilities. (See Mortgage, Sec. 96). ISSUANCE OF ADDITIONAL BONDS Bonds may be issued from time to time on the basis of (1) 60% of property additions, after adjustments to offset retirements (see "Modification of the Mortgage -- Issuance of Additional Bonds" below); (2) retirement of Bonds or qualified lien bonds; or (3) deposit of cash. With certain exceptions in the case of (2) above, the issuance of Bonds is subject to adjusted net earnings before income taxes for 12 consecutive months out of the preceding 15 months being at least twice the annual interest requirements on all Bonds at the time outstanding, including the additional issue, and all indebtedness of prior rank. Property additions generally include gas, electric, steam or hot water property or gas by-product property acquired after March 31, 1946, but may not include securities, airplanes, automobiles or other vehicles, or natural gas transmission lines or natural gas and oil production property. As of December 31, 1996, approximately $373 million of property additions and $93 million of retired Bonds were available for use as the basis for the issuance of Bonds. 6 The Mortgage contains certain restrictions upon the issuance of Bonds against property subject to liens. The Secured Notes will be issued against property additions and retired Bonds. (See Mortgage, Secs. 4-7, 20-30 and 46, and Third Supplemental, Secs. 3 and 4.) RELEASE AND SUBSTITUTION OF PROPERTY Property may be released against (1) deposit of cash or, to a limited extent, purchase money mortgages, (2) property additions, or (3) waiver of the right to issue Bonds without applying any earnings test. Cash so deposited and cash deposited against the issuance of additional bonds may be withdrawn upon the bases stated in (2) and (3) above. When property released is not funded property, property additions used to effect the release may again, in certain cases, become available as credits under the Mortgage, and the waiver of the right to issue Bonds to effect the release may, in certain cases, cease to be effective as such a waiver. Similar provisions are in effect as to cash proceeds of such property. The Mortgage contains special provisions with respect to qualified lien bonds pledged and the disposition of moneys received on pledged prior lien bonds. (See Mortgage, Secs. 5, 31, 32, 37, 46 to 50, 59 to 61, 100 and 118.) DEFAULTS AND NOTICE THEREOF Defaults are: default in payment of principal, default for 60 days in payment of interest or of installments of funds for retirement of Bonds; certain defaults with respect to qualified lien bonds; certain events in bankruptcy, insolvency or reorganization; and default for 90 days after notice in the case of a breach of any other covenant. The Mortgage Trustees may withhold notice of default (except in payment of principal, interest or any fund for the retirement of Bonds) if they think it in the interest of the Bondholders. (See Mortgage, Secs. 65 and 66.) Holders of 25% of the Bonds may declare the principal and the interest due on default, but a majority may annul such declaration if such default has been cured. No holder of Bonds may enforce the lien of the Mortgage without giving the Mortgage Trustees written notice of a default and unless holders of 25% of the Bonds have requested the Mortgage Trustees to act and offered them reasonable opportunity to act and the Mortgage Trustees have failed to act. The Mortgage Trustees are not required to risk their funds or incur personal liability if there is reasonable ground for believing that the repayment is not reasonably assured. Holders of a majority of the Bonds may direct the time, method and place of conducting any proceedings for any remedy available to the Mortgage Trustees, or exercising any trust or power conferred upon the Mortgage Trustees, but the Mortgage Trustees are not required to follow such direction if not sufficiently indemnified for expenditures. (See Mortgage, Secs. 67, 71, 80 and 94.) SATISFACTION AND DISCHARGE OF MORTGAGE The lien of the Mortgage may be cancelled and discharged whenever all indebtedness secured by the Mortgage has been paid. Bonds, or any portion of the principal amount thereof, will, prior to the maturity thereof, be deemed to have been paid for purposes of satisfying the lien of the Mortgage and shall not be deemed to be outstanding for any other purpose of the Mortgage if there shall have been deposited with the Corporate Trustee either (i) moneys in the necessary amount or (ii) (a) direct obligations of the government of the United States of America or (b) obligations guaranteed by the government of the United States of America or (c) securities that are backed by obligations of the government of the United States of America as collateral under an arrangement by which the interest and principal payments on the collateral generally flow immediately through to the holder of the security, which in any case are not subject to redemption prior to maturity by anyone other than the holders, the principal of and the interest on which when due, and without any regard to reinvestment thereof, shall be sufficient to pay when due the principal of, premium, if any, and interest due and to become due on said Bonds or portions thereof on the redemption date or maturity date thereof, as the case may be. (See Mortgage, Sec. 106 and Thirteenth Supplemental, Sec. 3.02.) EVIDENCE TO BE FURNISHED TO THE MORTGAGE TRUSTEES Compliance with Mortgage provisions is evidenced by written statements of the Company's officers or persons selected by the Company. In certain major matters the accountant, engineer, appraiser or other expert must be independent. Various certificates and other papers, including an annual certificate with reference to compliance with the terms of the Mortgage and absence of defaults, are required to be filed annually and upon the occurrence of certain events. (See Mortgage, Secs. 38-46.) 7 MODIFICATION OF THE MORTGAGE The rights of the Bondholders may be modified with the consent of 70% of the Bonds and, if less than all series of Bonds are affected, the consent also of 70% of Bonds of each series affected. The Company has the right, without any consent or other action by holders of any series of Bonds, to substitute 66 2/3% for 70%. In general, no modification of the terms of payment of principal and interest, affecting the lien of the Mortgage or reducing the percentage required for modification (except as provided above) will be effective against any Bondholder without his consent. (See Mortgage, Art. XIX and Ninth Supplemental, Sec.6.) The Company has reserved the right to amend the Mortgage, without any consent or other action by holders of the Bonds of the Nineteenth Series or of Bonds of any subsequently created series (including the Secured Notes), in the following respects: Release and Substitution of Property To permit the release of property at the lesser of its cost or its fair value at the time that such property became funded property, rather than at its fair value at the time of its release; and to facilitate the release of unfunded property. (See Mortgage, Secs. 3, 59 and 60 and Eighteenth Supplemental, Sec. 2.03.) Issuance of Additional Bonds To clarify that (i) for purposes of determining annual interest requirements, interest on Bonds or other indebtedness bearing interest at a variable interest rate shall be computed at the average of the interest rates borne by such Bonds or other indebtedness during the period of calculation or, if such Bonds or other indebtedness shall have been issued after such period or shall be the subject of pending applications, interest shall be computed at the initial rate borne upon issuance, and (ii) no extraordinary items shall be included in operating expenses or deducted from revenues or other income in calculating adjusted net earnings (See Mortgage, Sec. 7.); and to revise the basis for the issuance of additional Bonds from 60% of property additions, after adjustments to offset retirements, to 70%. (See Mortgage, Secs. 25, 26, 59 and 61 and Eighteenth Supplemental, Secs. 2.01 and 2.02.) THE CORPORATE TRUSTEE Bankers Trust Company also serves as the Indenture Trustee under the Indenture under which the Unsecured Notes are issued. DESCRIPTION OF THE UNSECURED NOTES GENERAL The Unsecured Notes are to be issued under an Indenture, dated as of June 1, 1991 ("Indenture"), between the Company and Bankers Trust Company, as trustee ("Indenture Trustee"). The statements herein concerning the Unsecured Notes and the Indenture are merely an outline and do not purport to be complete. They make use of terms defined in the Indenture and are qualified in their entirety by express reference to the cited Sections and Articles. They may be changed with respect to any Unsecured Note by the applicable Pricing Supplement, which should be read in conjunction with this description. The Indenture provides that debt securities (including the Unsecured Notes and including both interest bearing and original issue discount securities) may be issued thereunder, without limitation as to aggregate principal amount. (See Indenture, Sec. 301.) All debt securities heretofore or hereafter issued under the Indenture (including the Unsecured Notes) are collectively referred to as the "Indenture Securities". The Indenture does not limit the amount of other debt, secured or unsecured, which may be issued by the Company. The Unsecured Notes will rank pari passu with all other unsecured and unsubordinated indebtedness of the Company. Substantially all of the gas plants, distribution systems and other materially important physical properties of the Company are subject to the lien of the Mortgage securing the Company's Bonds. (See "Description of the Secured Notes--Security and--Issuance of Additional Bonds", above.) The Unsecured Notes will be offered on a continuing basis, and each Unsecured Note will mature on such date, not less than nine months nor more than 30 years from its date of issue, as selected by the purchaser and agreed to by the Company. 8 The Pricing Supplement relating to any Unsecured Note will set forth the principal amount, interest rate, issue price and Agent's commission, original issue and maturity dates, redemption provisions, if any, and other material terms of such Unsecured Note. INTEREST Interest on each Unsecured Note will be payable semi-annually in arrears on June 1 and December 1 of each year and at maturity. Interest payable on any interest payment date for any Unsecured Note will be payable to the person in whose name such Unsecured Note is registered on the record date with respect to such interest payment date, which shall be the May 15 or November 15 (whether or not a business day), as the case may be, next preceding such interest payment date; provided that, (i) if the original issue date of any Unsecured Note is after a record date and before the corresponding interest payment date, such Unsecured Note will bear interest from the original issue date but payment of interest shall commence on the second interest payment date succeeding the original issue date, and (ii) interest payable on the maturity date will be payable to the person to whom the principal thereof shall be payable. Unless otherwise indicated in the applicable Pricing Supplement, interest on the Unsecured Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. FORM, EXCHANGE AND PAYMENT The Unsecured Notes will be issued in fully registered form in denominations of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. The Unsecured Notes will be exchangeable at the office of Bankers Trust Company in New York City, without charge other than taxes or other governmental charges incident thereto. Principal, premium, if any, and interest will be payable at such office. Notwithstanding the foregoing, for so long as the Unsecured Notes shall be held by the Depository or its nominee, owners of beneficial interests in the Unsecured Notes will not be entitled to have any individual Unsecured Notes registered in their names, and transfers of beneficial interests and payments of principal, premium, if any, and interest will be made as described herein under "Book-Entry System". REDEMPTION To the extent, if any, provided in the Pricing Supplement relating to any Unsecured Note, such Unsecured Note will be redeemable, on not less than 30 days' notice, in whole or in part, at any time on or after the initial redemption date, if any, fixed at the time of sale and set forth in the applicable Pricing Supplement. On or after the initial redemption date, such Unsecured Note will be redeemable in whole or in part, at the option of the Company, at a redemption price determined in accordance with the following paragraph, plus accrued interest to the date fixed for redemption. The redemption price for each Unsecured Note subject to redemption shall, for the twelve-month period commencing on the initial redemption date, be equal to a certain percentage of the principal amount of such Unsecured Note and, thereafter, shall decline for the twelve-month period commencing on each anniversary of the initial redemption date by a percentage of principal amount ("Reduction Percentage") until the redemption price shall be 100% of the principal amount. The initial redemption price and date and any Reduction Percentage with respect to each Unsecured Note subject to redemption will be fixed at the time of sale and set forth in the applicable Pricing Supplement. If so specified in the Pricing Supplement relating to any Unsecured Note, the Company may not, prior to the redemption limitation date, if any, set forth in such Pricing Supplement, redeem such Unsecured Note as contemplated above as a part of, or in anticipation of, any refunding operation by the application, directly or indirectly, of moneys borrowed having an effective interest cost to the Company (calculated in accordance with generally accepted financial practice) of less than the effective interest cost to the Company (similarly calculated) of such Unsecured Note. If, at the time the notice of redemption shall be given, the redemption money shall not be on deposit with the Indenture Trustee, the redemption shall be made subject to the receipt of such money on or before the date fixed for redemption, and such notice shall be of no effect unless such money shall be so received. (See Indenture, Art. Four.) Unless otherwise indicated in the applicable Pricing Supplement, the Unsecured Notes will not be subject to any sinking fund. 9 DEFEASANCE The principal amount of any Unsecured Notes issued under the Indenture will be deemed to have been paid for purposes of the Indenture and the entire indebtedness of the Company in respect thereof will be deemed to have been satisfied and discharged, if there shall have been irrevocably deposited with the Indenture Trustee, in trust: (a) money in an amount which will be sufficient, or (b) in the case of a deposit made prior to the maturity of the Unsecured Notes, Government Obligations (as defined herein), which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Indenture Trustee, will be sufficient, or (c) a combination of (a) and (b) which will be sufficient, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the Unsecured Notes that are outstanding. For this purpose, Government Obligations include direct obligations of, or obligations unconditionally guaranteed by, the United States of America entitled to the benefit of the full faith and credit thereof and certificates, depositary receipts or other instruments which evidence a direct ownership interest in such obligations or in any specific interest or principal payments due in respect thereof. (See Indenture, Secs. 101, 701.) If the Company shall make any deposit of money and/or Government Obligations with respect to the Unsecured Notes, or any portion of the principal amount thereof, prior to the Maturity or redemption of such Unsecured Notes or such portion of the principal amount thereof, for the satisfaction or discharge of the indebtedness of the Company in respect to such Unsecured Notes or such portion thereof as contemplated by Section 701 of the Indenture, the Company shall deliver to the Indenture Trustee either (a) an instrument wherein the Company, notwithstanding such satisfaction and discharge, shall assume the obligation (which shall be absolute and unconditional) to irrevocably deposit with the Indenture Trustee such additional sums of money, if any, or additional Government Obligations, if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Government Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due and to become due on such Unsecured Notes or such portions thereof, all in accordance with and subject to the provisions of said Section 701; provided, however, that such instrument may state that the obligation of the Company to make additional deposits as aforesaid shall be subject to the delivery to the Company by the Indenture Trustee of a notice asserting the amount of such deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing, selected by the Indenture Trustee, showing the calculation thereof, or (b) an opinion of Counsel to the effect that the Holders of such Unsecured Notes, or such portions of the principal amount thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of such satisfaction and discharge and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such satisfaction and discharge had not been effected. In the event that the Company shall elect to deliver to the Indenture Trustee an instrument as described in clause (a) of the preceding paragraph in connection with any such deposit of money and/or Government Obligations with the Indenture Trustee, under current applicable United States federal income tax regulations, the Holders of such Unsecured Notes, or such portions thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of such satisfaction and discharge and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such deposit had not been effected. There can be no assurance that such United States federal income tax regulations will not change such that, as a result of such deposit and delivery by the Company of such instrument, Holders may recognize income, gain or loss for United States federal income tax purposes and may not be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such deposit had not been effected. EVENTS OF DEFAULT AND NOTICE THEREOF Events of Default are: default for three Business Days in payment of principal; default for 60 days in payment of interest; certain events in bankruptcy, insolvency or reorganization; default for 90 days after notice in the case of a breach of any other covenant; and any other Event of Default specified with respect to the Indenture Securities of a particular series. No Event of Default with respect to a series of Indenture Securities necessarily constitutes an Event of Default with respect to the Indenture Securities of any other series. The Indenture Trustee may withhold notice of default (except in payment of principal, interest or any funds for the retirement of Indenture Securities) if it, in good faith, determines that withholding of such notice is in the interest of the Holders of the Indenture Securities. (See Indenture, Secs. 801 and 903.) Either the Indenture Trustee or the Holders of not less than 33% in principal amount (or such lesser amount as may be provided in the case of discount Indenture Securities) of the outstanding Indenture Securities of all defaulted series, considered as one class, may declare the principal and interest on such series due on default, but the Company may annul such default by effecting its cure and paying overdue interest and principal. No Holder of 10 Indenture Securities may enforce the Indenture without having given the Indenture Trustee written notice of default, and unless the Holders of a majority of the Indenture Securities of all defaulted series, considered as one class, shall have requested the Indenture Trustee to act and offered reasonable indemnity, and for 60 days the Indenture Trustee shall have failed to act. But, each Holder has an absolute right to receive payment of principal and interest when due and to institute suit for the enforcement of such payment. The Indenture Trustee is not required to risk its funds or incur any financial liability if it shall have reasonable grounds for believing that repayment is not reasonably assured. The Holders of a majority of the Indenture Securities of all defaulted series, considered as one class, may direct the time, method and place of conducting any proceedings for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee, with respect to the Indenture Securities of such series, but the Indenture Trustee is not required to follow such direction if not sufficiently indemnified and the Indenture Trustee may take any other action it deems proper which is not inconsistent with such direction. (See Indenture, Secs. 802, 807, 808, 812 and 902.) EVIDENCE TO BE FURNISHED TO THE INDENTURE TRUSTEE Compliance with Indenture provisions will be evidenced by written statements of the Company's officers. An annual certificate with reference to compliance with the covenants and conditions of the Indenture and the absence of defaults is required to be filed with the Indenture Trustee. (See Indenture, Sec.1004.) MODIFICATION OF THE INDENTURE The rights of the Holders of the Indenture Securities may be modified with the consent of the Holders of a majority of the Indenture Securities of all series or Tranches, as defined below, affected, considered as one class. However, certain specified rights of the Holders of Indenture Securities may be modified without the consent of the Holders if such modification would not be deemed adversely to affect their interests in any material respect. In general, no modification of the terms of payment of principal and interest, no reduction of the percentage in principal amount of the Indenture Securities outstanding under such series required to consent to any supplemental indenture or waiver under the Indenture, no reduction of such percentage necessary for quorum and voting, and no modification of certain of the provisions in the Indenture relating to supplemental indentures, waivers of certain covenants and waivers of past defaults is effective against any Holder of Indenture Securities without his consent. "Tranche" means a group of Indenture Securities which are of the same series and have identical terms except as to principal amount and/or date of issuance. (See Indenture, Art. Twelve.) THE INDENTURE TRUSTEE Bankers Trust Company also serves as the Corporate Trustee under the Mortgage under which the Secured Notes are issued. PLAN OF DISTRIBUTION The Medium-Term Notes are being offered on a continuing basis for sale by the Company through the Agents which have agreed to use their best efforts to solicit purchases of the Medium-Term Notes. The initial Agents are Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and PaineWebber Incorporated. Should the Company designate other persons to act as Agents, the names of such persons will be disclosed in a Pricing Supplement. The Company will pay each Agent a commission which, depending on the maturity of the Medium-Term Notes, will range from .125% to .750% of the principal amount of any Medium-Term Note sold through such Agent. The Company may also sell Medium-Term Notes to any Agent, as principal, at a discount from the principal amount thereof, and the Agent may later resell such Medium-Term Notes to investors and other purchasers at varying prices related to prevailing market prices at the time of resale as determined by such Agent or, if so agreed, at a fixed public offering price. In the case of sales to any Agent as principal, such Agent may utilize a selling or dealer group in connection with resales. An Agent may sell Medium-Term Notes it has purchased as principal to any dealer at a discount and, unless otherwise specified in the applicable Pricing Supplement, such discount allowed to any dealer will not be in excess of the discount to be received by such Agent from the Company. After the initial public offering of Medium-Term Notes to be resold to investors and other purchasers, the public offering price (in the case of a fixed price public offering), concession and discount may be changed. The Medium-Term Notes also may be sold by the Company directly to purchasers. No commission will be payable to the Agents on Medium-Term Notes sold directly by the Company. The Company reserves the right to withdraw, cancel or modify the offer made hereby without notice and may reject, in whole or in part, offers to purchase Medium-Term Notes whether placed directly with the Company or through one of the Agents. Each Agent will have the right, in its discretion reasonably exercised, to reject any offer to purchase Medium-Term Notes received by it, in whole or in part. 11 Payment of the purchase price of the Medium-Term Notes will be required to be made in immediately available funds in New York City on the date of settlement. No Medium-Term Note will have an established trading market when issued. The Medium-Term Notes will not be listed on any securities exchange. Each of the Agents may from time to time purchase and sell Medium-Term Notes in the secondary market, but is not obligated to do so. There can be no assurance that there will be a secondary market for the Medium-Term Notes or liquidity in the secondary market if one develops. From time to time, each of the Agents may make a market in the Medium-Term Notes. The Agents may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, as amended. The Company has agreed to indemnify each of the Agents against, or to make contributions relating to, certain liabilities, including liabilities under such Act. The Company has agreed to reimburse each of the Agents for certain expenses. Each of the Agents may engage in transactions with, or perform services for, the Company in the ordinary course of business. In connection with certain types of offers and sales of Medium-Term Notes, rules of the Securities and Exchange Commission permit the Agents to engage in certain transactions that stabilize the price of such Medium-Term Notes. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Medium-Term Notes. If the Agents create a short position in any Medium-Term Notes in connection with certain types of offers and sales, i.e., if they sell more Medium-Term Notes than are set forth in the applicable Pricing Supplement, the Agents may reduce that short position by purchasing Medium-Term Notes in the open market. In connection with certain types of offers and sales, the Agents may also impose a penalty bid on certain Agents and selling group members. This means that if the Agents purchase Medium-Term Notes in the open market to reduce the Agents' short position or to stabilize the price of the Medium-Term Notes, they may reclaim the amount of selling concession from the Agents and selling group members who sold these Medium-Term Notes as part of the offering. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a security to the extent that it were to discourage resales of the security. Neither the Company nor any Agent makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Medium-Term Notes. In addition, neither the Company nor any Agent makes any representation that the Agents will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Oregon Business Corporation Act (the "Act") provides, in general, that a director or officer of a corporation who has been or is threatened to be made a defendant in a legal proceeding because that person is or was a director or officer of the corporation: (1) shall be indemnified by the corporation for all expenses of such litigation when the director or officer is wholly successful on the merits or otherwise; (2) may be indemnified by the corporation for the expenses, judgments, fines and amounts paid in settlement of such litigation (other than a derivative lawsuit) if he or she acted in good faith and in a manner reasonably believed to be in, or at least not opposed to, the best interests of the corporation (and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful); and (3) may be indemnified by the corporation for expenses of a derivative lawsuit (a suit by a shareholder alleging a breach by a director or officer of a duty owed to the corporation) if he or she acted in good faith and in a manner reasonably believed to be in, or at least not opposed to, the best interests of the corporation, provided the director or officer is not adjudged liable to the corporation. The Act also authorizes the advancement of litigation expenses to a director or officer upon receipt of a written affirmation of the director's or officer's good faith belief that the standard of conduct in Section (2) or (3) above has been met and an undertaking by such director or officer to repay such expenses if it is ultimately determined that he or she did not meet that standard and, therefore, is not entitled to be indemnified. The Act also provides that the indemnification provided thereunder shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise. The Company's Bylaws provide that the Company shall indemnify directors and officers to the fullest extent permitted under the Act, thus making mandatory the discretionary indemnification authorized by the Act. The Company's Restated Articles of Incorporation provide that the Company shall indemnify its officers and directors to the fullest extent permitted by law, which may be broader than the indemnification authorized by the Act. The Company's shareholders have approved and the Company has entered into indemnity agreements with its directors and officers which provide for indemnity to the fullest extent permitted by law and also alter or clarify the statutory indemnity in the following respects: (1) prompt advancement of litigation expenses is provided if the director or officer makes the required affirmation and undertaking; (2) the director or officer is permitted to enforce the indemnity obligation in court and the burden is on the Company to prove that the director or officer is not entitled to indemnification; II-1 (3) indemnity is explicitly provided for judgments and settlements in derivative actions; (4) prompt indemnification is provided unless a determination is made that the director or officer is not entitled to indemnification; and (5) partial indemnification is permitted if the director or officer is not entitled to full indemnification. The Company maintains in effect a policy of insurance providing for reimbursement to the Company of payments made to directors and officers as indemnity for damages, judgments, settlements, costs and expenses incurred by them which the Company may be required or permitted to make according to applicable law, common or statutory, or under provisions of its Restated Articles of Incorporation, Bylaws or agreements effective under such laws.

II-2 ITEM 17. UNDERTAKINGS. The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that the undertakings set forth in paragraphs (i) and (ii) above do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement. (2) That, for the purpose of determining liability under the Securities Act of 1933, each such post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes, that for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 15 of this registration statement, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indem- nification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Portland, and State of Oregon on the twenty-second day of April, 1997.

The Secured Notes will be issued under the Company's Mortgage and Deed of Trust, dated as of July 1, 1946, to Bankers Trust Company (the "Mortgage Trustee" or the "Trustee") and R.G. Page (Stanley Burg, successor), as trustees, as supplemented (such Mortgage and Deed of Trust as supplemented being hereinafter referred to as the "Mortgage" or the "Indenture"). The Unsecured Notes will be issued under an indenture, dated as of June 1, 1991 (the "Note Indenture" or the "Indenture"), between the Company and Bankers Trust Company, as trustee (the "Indenture Trustee" or the "Trustee"). The Securities shall have the maturities, interest rates, if any, redemption provisions and other terms set forth in the Prospectus referred to below, as it may be amended or supplemented from time-to-time. The Securities will be issued, and the terms thereof established, from time-to-time, by the Company in accordance with the respective Indentures. The Company represents, warrants, covenants and agrees with each of you and with each other person which shall become a party to this agreement (individually, an "Agent", and collectively, the "Agents") and each Agent, severally and not jointly, covenants and agrees with the Company as follows: 1. Representations and Warranties of the Company. The Company --------------------------------------------- represents and warrants to each Agent that: (a) The Company is a corporation duly organized and validly existing in good standing under the laws of the State of Oregon, and is qualified to do business and is in good standing as a foreign corporation in the State of Washington, with power (corporate and other) to own its properties and conduct its business as described in the Prospectus referred to below. (b) An initial registration statement on Form S-3 (Registration No. 33-64014) (the "Initial Registration Statement") in respect of $150,000,000 aggregate principal amount of the Company's First Mortgage Bonds designated Secured Medium-Term Notes Series B, and Unsecured Medium-Term Notes Series B (of which $15,000,000 remain unsold on the date hereof) has been filed with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"), in the form heretofore delivered (excluding the exhibits thereto but including the documents incorporated by reference in the prospectus included therein) to such Agent, and such Initial Registration Statement in such form has been declared effective by the Commission and no stop order suspending its effectiveness has been issued and no proceeding for that purpose has been initiated or threatened by the Commission. A subsequent registration statement on Form S-3 (Registration No. 333-15323), as amended (the "Subsequent Registration Statement"), in respect of an additional $150,000,000 aggregate principal amount of the Securities has been filed with the Commission under the Act, in the form heretofore delivered or to be delivered (excluding the exhibits thereto but including the documents incorporated by reference in the prospectus included therein) to such Agent, and such Subsequent Registration Statement in such form has been declared effective by the Commission and no stop order suspending its effectiveness has been issued and no proceeding for that purpose has been initiated or threatened by the Commission (any preliminary prospectus included in the Subsequent Registration Statement being hereinafter called a "Pre- liminary Prospectus"). The Initial Registration Statement and the Subsequent Registration Statement, including all exhibits thereto but excluding Forms T-1 and T-2, as amended at the time each became effective, are hereinafter called the "Registration Statement"; the combined prospectus included as a part of the Subsequent Registration Statement (including, if applicable, any prospectus supplement) relating to the Securities, in the form in which it most recently has been filed with the Commission on or prior to the date of this Agreement, is hereinafter called the "Prospectus"; any reference herein to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents filed by the Company under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and incorporated therein by reference as of the date of such Preliminary Prospectus or Prospectus; any reference to any amendment or supplement to any Preliminary Prospectus or Prospectus, including any supplement to the Prospectus that sets forth only the terms of a particular issue of the Securities (a "Pricing Supplement"), shall be deemed to refer to and include the documents filed by the Company under the Exchange Act and incorporated therein by reference as of the date of such amendment or Pricing Supplement; and any reference to the Prospectus as amended or supplemented shall be deemed to refer to and include the Prospectus as then amended or supplemented (including the applicable Pricing Supplement) in relation to a particular issue of Securities, in the form filed with the Commission pursuant to Rule 424(b) under the Act, including any documents filed by the Company under the Exchange Act and incorporated therein by reference as of the date of such amendment or supplement. (c) The documents incorporated by reference in the Prospectus, when filed with the Commission or, if later, when they became effective, conformed in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the applicable rules and regulations of the Commission thereunder; none of such documents when so filed or when such documents became effective, as the case may be, included 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, in the light of the circumstances under which they were made, not misleading; any future documents so filed or incorporated by reference in the Prospectus, or any amendment or supplement thereto, when filed with the Commission or, if later, when effective, will conform in all material respects with the applicable requirements of the Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder, and when such documents are filed or become effective, as the case may be, they 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; provided, however, that the Company makes -------- ------- no representations or warranties as to information contained in or omitted from the Prospectus as amended or supplemented in reliance upon and in conformity with information furnished in writing to the Company by any Agent specifically for use therein; (d) The Initial Registration Statement and the Subsequent Registration Statement when each became effective conformed, and the Prospectus conforms, and any amendment or supplement thereto will conform, in all material respects, with the provisions of the Act and the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the rules and regulations of the Commission thereunder; and the Initial Registration Statement and the Subsequent Registration Statement when each became effective did not, the Prospectus does not (and on each of the dates referred to in clause (i) of Section 6 will not) and any amendment or supplement to the Prospectus, as of its date and on each of the dates referred to in clause (i) of Section 6, 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; provided, however, that the Company -------- ------- makes no representations or warranties as to information contained in or omitted from any such document in reliance upon and in conformity with information furnished in writing to the Company by any Agent specifically for use therein; (e) Except as set forth in or contemplated by the Prospectus, since the date as of which information is given in the Prospectus (i) there has not been any material adverse change in the condition of the Company and its subsidiaries taken as a whole, financial or otherwise, (ii) there has not been any transaction entered into by the Company or any of its subsidiaries which is material to the Company and its subsidiaries taken as a whole, other than transactions in the ordinary course of business, and (iii) neither the Company nor any of its subsidiaries has incurred any contingent obligation which is material to the Company and its subsidiaries taken as a whole; (f) The Securities have been duly authorized, and, when issued pursuant to their respective Indentures and delivered pursuant to this Agreement and any Terms Agreement (as defined in Section 3 hereof), will have been duly executed, authenticated, issued and delivered, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, except as their enforceability may be limited by laws and principles of equity relating to or affecting generally the enforcement of creditors' rights, including without limitation, bankruptcy and insolvency laws, and will be entitled to the benefits provided by their respective Indentures (which will be substantially in the form filed as exhibits to the Subsequent Registration Statement); the Indentures have been duly authorized and qualified under the Trust Indenture Act, consti- tute valid and legally binding instruments, enforceable in accordance with their terms, except as their enforceability may be limited by laws and principles of equity relating to or affecting generally the enforcement of creditors' rights, including without limitation, bankruptcy and insolvency laws; and the Indentures conform, and the Securities of each issue, when issued, will conform, in all material respects, to the descriptions thereof in the Prospectus as amended or supplemented with respect to such issue; (g) The issue and sale of the Securities, the compliance by the Company with all of the provisions of the Securities, the Indentures, this Agreement and any Terms Agreement, and the consummation by the Company of the transactions herein and therein contemplated will not result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property of the Company is subject, nor will such action result in any violation of the provisions of any statute or the Restated Articles of Incorporation, as amended, or the Bylaws, as amended, of the Company or any order, rule or regulation of any court or any regulatory authority or other governmental agency or body having jurisdiction over the Company or any of its properties; and no consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required for the solicitation of offers to purchase Securities and the issue and sale of the Securities or the consummation by the Company of the other transactions contemplated by the Indentures, this Agreement or any Terms Agreement, except such as have been obtained at or prior to the Commencement Date (as defined in Section 4 hereof), will have been obtained under the Act, the Trust Indenture Act and the public utility laws of the States of Oregon and Washington and such as may be required under state securities or Blue Sky laws in connection with the solicitation by such Agent of offers to purchase Securities from the Company and with purchases of Securities by such Agent as principal, as the case may be, in each case in the manner contemplated hereby; and (h) Other than as set forth or contemplated in the Prospectus, there are no legal or governmental proceedings pending to which the Company is a party or to which any property of the Company is subject, which, if determined adversely to the Company, would individually or in the aggregate have a material adverse effect on the consolidated financial position, stockholders' equity or consolidated results of operations of the Company, and, to the best of the Company's knowledge, no such proceedings are threatened. 2. Obligations of the Agents and the Company. ----------------------------------------- (a) Subject to the terms and conditions hereof and to the reservation by the Company of the right to sell Securities directly on its own behalf, the Company hereby (i) appoints each of Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and PaineWebber Incorporated as an agent of the Company for the purpose of soliciting and receiving offers to purchase Securities from the Company and (ii) reserves the right, from time to time, to appoint additional agents for the purpose of soliciting and receiving offers to purchase Securities from the Company; provided that each such additional agent shall be required to become a party to this Agreement and undertake the obligations of an Agent hereunder pursuant to an Additional Agent Appointment Agreement ("Additional Agent Appointment Agreement") substantially in the form of Exhibit 1 hereto. (b) On the basis of the representations and warranties herein, and subject to the terms and conditions hereof, each of the Agents, as agent of the Company, severally and not jointly, agrees to use its reasonable best efforts to solicit and receive offers to purchase particular issues of the Securities from the Company upon the terms and conditions set forth in the Prospectus as amended or supplemented with respect thereto. Each Agent will promptly advise the Company by telephone or other appropriate means of all reasonable offers to purchase Securities, other than those rejected by such Agent. The Company shall not, without the consent of each Agent, which consent shall not unreasonably be withheld, solicit or accept offers to purchase, or sell, any debt securities with a maturity, at the time of original issuance, of from nine months to 30 years, except (i) pursuant to this Agreement, (ii) pursuant to a private placement not constituting a public offering under the Act, or (iii) in connection with a firm commitment underwriting pursuant to an underwriting agreement that does not provide for a continuous offering. However, the Company, subject to Section 5(f) hereof, reserves the right to sell, and may solicit and accept offers to purchase, Securities directly on its own behalf, and, in the case of any such sale not resulting from a solicitation made by an Agent, no commission will be payable with respect to such sale. (c) Procedural details relating to the issue and delivery of Securities, the solicitation of offers to purchase Securities and the payment therefor, unless an Agent and the Company shall otherwise agree, shall be as set forth in the Administrative Procedure attached hereto as Annex I (the "Administrative Procedure"). The provisions of the Administrative Procedure shall apply to all transactions contemplated hereunder other than those made pursuant to a Terms Agreement. Each Agent and the Company shall perform the respective duties and obligations specifically provided to be performed by each of them in the Administrative Procedure. The Company will furnish to the Trustees a copy of the Administrative Procedure as from time to time in effect. (d) The Company reserves the right, in its sole discretion, to instruct the Agents to suspend, at any time, for any period of time or permanently, the solicitation of offers to purchase the Securities. As soon as practicable, but in any event not later than one business day after receipt of notice from the Company, the Agents will suspend solicitation of offers to purchase Securities from the Company until such time as the Company has advised the Agents that such solicitation may be resumed. (e) The Company agrees to pay each Agent a commission, at the time of settlement (each a "Settlement Date") of any sale of a Security by the Company as a result of a solicitation made by such Agent, in an amount equal to the following applicable percentage of the principal amount of such Security sold: Commission (percentage of aggregate principal amount Range of Maturities of Securities sold) ------------------- ------------------- From 9 months to less than 1 year .125% From 1 year to less than 18 months .150% From 18 months to less than 2 years .200% From 2 years to less than 3 years .250% From 3 years to less than 4 years .350% From 4 years to less than 5 years .450% From 5 years to less than 6 years .500% From 6 years to less than 7 years .550% From 7 years to less than 10 years .600% From 10 years to less than 15 years .625% From 15 years to less than 20 years .675% From 20 years to 30 years .750% 3. Sales to Agents as Principal. Each sale of Securities to an ---------------------------- Agent, as principal, shall be made in accordance with the terms of this Agreement and (unless the Company and such Agent shall otherwise agree) a separate agreement (each a "Terms Agreement"), which will provide for the sale of such Securities to, and the purchase thereof by, such Agent, as principal. A Terms Agreement may be either (i) a written agreement substantially in the form of Annex II hereto, or (ii) an oral agreement between either Agent and the Company confirmed in writing by such Agent. A Terms Agreement may also specify certain provisions relating to the reoffering of such Securities by such Agent. Each Terms Agreement shall specify the principal amount of Securities to be purchased by an Agent pursuant thereto, the price to be paid to the Company for such Securities, any provisions relating to the rights of, and defaults by, any underwriters acting together with such Agent in the reoffering of the Securities, the time and date of delivery of and payment for such Securities (each, a "Time of Delivery") and place of delivery of such Securities, and any requirements for opinions of counsel, accountants' letters and officers' certificates pursuant to Section 5 hereof. Each purchase of Securities, unless otherwise agreed shall be at a discount equivalent to the commission payable to an Agent, acting as agent, with respect to a sale of Securities of identical maturity, as set forth in Section 2(e) hereof). The Agent may engage the services of any other broker or dealer in connection with the resale of the Securities purchased as principal and may allow any portion of the discount received in connection with such purchase from the Company to be paid to such brokers and dealers. The commitment of an Agent to purchase Securities as principal, whether pursuant to a Terms Agreement or otherwise, shall be deemed to have been made on the basis of the represen- tations and warranties of the Company herein contained and, to the extent not otherwise agreed upon in a Terms Agreement or otherwise, shall be subject to the terms and conditions herein set forth. 4. Commencement. At 11:00 a.m., New York City time, on the ------------ date of this Agreement or at such later date and time as may be agreed upon between the Agents and the Company not later than the day prior to the earlier of the day on which the solicitation of offers to purchase Securities is to begin or on which any Terms Agreement shall be executed (such time and date being referred to herein as the "Commencement Date"), the Agents shall be furnished at the offices of Reid & Priest LLP, 40 West 57th Street, New York, New York: (a) An opinion of Simpson Thacher & Bartlett (a partnership which includes professional corporations), counsel to the Agents, dated the Commencement Date, with respect to such matters as such Agents may reasonably request, which opinion may rely, as to all matters governed by Oregon and Washington law, upon the opinion of Bruce B.

Covenants of the Company. The Company covenants and agrees ------------------------ with each Agent: (a) (i) To make no amendment or supplement to the Registration Statement or the Prospectus (other than a Pricing Supplement) (A) prior to the Commencement Date, which any Agent shall reasonably disapprove by notice to the Company promptly after receipt of the proposed form thereof or (B) after the date of any agreement by such Agent, pursuant to a Terms Agreement or otherwise, to purchase Securities as principal and prior to the related Time of Delivery which such Agent shall reasonably disapprove by notice to the Company promptly after receipt of the proposed form thereof; (ii) to prepare, with respect to each particular issue of Securities to be sold through or to such Agent pursuant to this Agreement, a Terms Agreement or otherwise, a Pricing Supplement with respect to such Securities in a form reasonably satisfactory to such Agent and to file such Pricing Supplement in accordance with Rule 424(b) under the Act; (iii) to make no amendment or supplement to the Registration Statement or Pro- spectus, other than a Pricing Supplement, without affording such Agent a reasonable opportunity for review thereof and comment thereon; (iv) to timely file all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the delivery of a prospectus is required in connection with the offering or sale of the Securities, and during such same period to advise such Agent, promptly after the Company receives notice thereof, of the time when any amendment to the Registration Statement has been filed or has become effective or any supplement to the Prospectus or any amended Prospectus (other than any Pricing Supplement that relates to Securities not purchased through or by such Agent) has been filed with the Commission, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any prospectus relating to the Securities, of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amendment or supplement of the Registration Statement or Prospectus or for additional information; (v) to promptly make every reasonable effort to comply with all requests of the Commission for additional information; and (vi) in the event of the issuance of any such stop order or of any such order preventing or suspending the use of any such prospectus or suspending any such qualification, to use its best efforts to obtain its withdrawal; (b) From time-to-time, to take such action as such Agent reasonably may request to qualify the Securities for offering and sale under the securities laws of such jurisdictions as may be approved by the Company and to comply with such laws so as to permit the continuance of sales and dealings therein for as long as may be necessary to complete the distribution or sale of the Securities; provided, however, that in connection therewith the Company shall not -------- ------- be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction, or to comply with any other requirement reasonably deemed by the Company to be unduly burdensome; provided, further, that the provisions of this subsection -------- ------- (b) shall not apply so long as the Securities are "covered securities" within the meaning of Section 18 of the Act and any rules and regulations thereunder; (c) To furnish such Agent with copies of the Registration Statement, each amendment thereto, the Prospectus and each amendment or supplement thereto, other than any Pricing Supplement (except as provided in the Administrative Procedure), in the form in which it is filed with the Commission pursuant to Rule 424(b) under the Act, and with copies of the documents incorporated by reference therein (other than exhibits incorporated by reference in the Registration Statement), each in such quantities as such Agent may reasonably request from time-to-time; and, if the delivery of a prospectus is required at any time in connection with the offering or sale of the Securities to or through an Agent pursuant to this Agreement and if, at such time, any event shall have occurred as a result of which the Prospectus as then amended or supplemented would include an 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, or, if for any other reason it shall be necessary during such period to amend or supplement the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the Act, the Exchange Act or the Trust Indenture Act, to notify such Agent and request such Agent, in its capacity as agent of the Company, to suspend solicitation of offers to purchase Securities from the Company (and, if so notified, such Agent shall cease such solicitations as soon as practicable, but in any event not later than one business day later); and if the Company shall decide to amend or supplement the Registration Statement or the Prospectus, to so advise such Agent promptly by telephone (confirmed in writing) and to prepare and cause to be filed promptly with the Commission an amendment or supplement to the Registration Statement or the Prospectus or to file any document incorporated by reference in the Prospectus that will correct such statement or omission or effect such compliance; provided -------- that, (i) should such event relate solely to activities of any Agent ---- (except any termination of any Agent's services hereunder), such Agent shall assume the expense of preparing and furnishing any such amend- ment or supplement; (ii) if, during such period, such Agent shall continue to own Securities purchased from the Company as principal or such Agent otherwise shall be required to deliver a prospectus in respect of transactions in the Securities, the Company shall promptly prepare and file with the Commission such an amendment or supplement; and (iii) if such Agent shall be required to deliver a prospectus in connection with sales of any Securities purchased by it as principal at any time nine months or more after the date of such purchase and (A) there shall be, as a result of such purchase, no Securities remaining to be sold under the Registration Statement or (B) the Company, pursuant to Section 2(d) hereof, shall have instructed the Agents, during such nine month period, to suspend permanently the solicitation of offers to purchase the Securities, such Agent shall assume the expense of preparing and furnishing any such amendment or supplement in connection with the sales of any Securities purchased by such Agent as principal. (For the purposes of this Section 5(c), the Company shall be entitled to assume that a Prospectus shall no longer be required to be delivered under the Act from and after the date six months from the date of the purchase by an Agent as principal of the particular issuance of Securities to which it relates, unless it shall have received notice from such Agent to the contrary);

(g) That each acceptance by the Company of an offer to purchase Securities procured by such Agent, as agent, and each agreement by the Company, pursuant to a Terms Agreement or otherwise, to sell Securities to such Agent, as principal, shall be deemed to be an affirmation to such Agent that the representations and warranties of the Company contained in or made pursuant to this Agreement are true and correct as of the date of such acceptance or agreement, as the case may be, as though made as of such date, and an undertaking that such representations and warranties will be true and correct as of the Settlement Date for the Securities relating to such acceptance or as of the Time of Delivery relating to such sale, as the case may be, as though made as of such date (except that such representations and warranties shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented relating to such Securi- ties); (h) That, reasonably in advance of (i) each date as of which an Agent reasonably requests an opinion or opinions of Simpson Thacher & Bartlett, counsel to the Agents, or other counsel to the Agents reasonably satisfactory to the Company, or (ii) each time that the Company sells Securities to such Agent as principal pursuant to a Terms Agreement or other agreement and such Agent requests an opinion or opinions by Simpson Thacher & Bartlett, counsel to the Agents, or other counsel to the Agents reasonably satisfactory to the Company, the Company shall furnish to such counsel such papers and information as they may reasonably request to enable them to furnish to such Agent a letter in form reasonably satisfactory to such Agent, to the effect that such Agent may rely on the opinion of such counsel referred to in Section 4(a) hereof, to the same extent as though it was dated the date of such letter (except that the statements in such opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to the date of such letter), or in lieu of such a letter, an opinion of the same tenor as the opinion of such counsel referred to in Section 4(a) hereof, but modified to relate to the Registration Statement and the Prospectus as amended and supple- mented to such date;

(ii) a letter of Reid & Priest LLP, New York, New York, counsel for the Company, or other counsel for the Company reasonably satisfactory to such Agent, dated the date of such amendment, supplement, incorporation or Time of Delivery relating to such sale, as the case may be, in form reasonably satisfactory to such Agent, to the effect that such Agent may rely on the opinion of such counsel referred to in Section 4(c) hereof to the same extent as though it were dated the date of such letter (except that the statements in such opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to the date of such letter, excluding, in the case of the statements in the paragraph next following paragraph 10 of such opinion, all documents filed by the Company under the Exchange Act and incorporated by reference into the Registration Statement and the Prospectus during or prior to the fiscal year which is the subject of the Company's most recent Annual Report on Form 10-K) or, in lieu of such letter, an opinion of the same tenor as the opinion of such counsel referred to in Section 4(c) hereof, but modified to relate to the Registration Statement and the Prospectus as so amended and supplemented to such date; and (iii) a certificate executed by the President or any Vice President of the Company, dated the date of such supplement, amendment, incorporation or Time of Delivery relating to such sale, as the case may be, in such form as shall be reasonably satisfactory to such Agent, to the effect that the statements contained in the certificate referred to in Section 4(e) hereof are true and correct at such date as though made as of such date (except that such statements shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to such date) or, in lieu of such certificate, a certificate of the same tenor as the certificate referred to in Section 4(e) hereof, but modified to relate to the Registration Statement and the Prospectus as amended and supplemented to such date; and (j) That each time that (x) the Registration Statement or the Prospectus shall be amended or supplemented to include additional financial information (unless waived by the Agents), and (y) the Company sells Securities to such Agent as principal pursuant to a Terms Agreement or other agreement and such Terms Agreement or other agreement specifies the delivery of a letter under this Section 5(j) as a condition to the purchase of Securities pursuant to such Terms Agreement or other agreement, and subject to compliance with the requirements of SAS issued by the American Institute of Certified Public Accountants, the Company shall furnish or cause to be furnished to such Agent letters of Deloitte & Touche LLP, Price Waterhouse LLP or other independent accountants for the Company reasonably satisfactory to the Agent, each with respect to periods during which such firm was the independent accountant for the Company, dated the date of such amendment, supplement, incorporation or Time of Delivery relating to such sale, as the case may be, in form reasonably satisfactory to such Agent, to the effect that such Agent may rely upon the letter of such accountants referred to in Section 4(d) hereof to the same extent as though it were dated the date of such subsequent letter (except the statements in such former letter shall be deemed to relate to the financial statements included or incorporated in the Registration Statement and Prospectus as amended and supplemented to the date of such latter letter), or, in lieu of such latter letter, a letter of the same tenor as the letter referred to in Section 4(d) hereof, but modified to relate to the Registration Statement and the Prospectus as amended or supplemented to the date of such letter, with such changes as may be necessary to reflect changes in the financial statements and other information derived from the accounting records of the Company, to the extent such financial statements and other information are available as of a date not more than five business days prior to the date of such letter; (k) To offer to any person who has agreed to purchase Securities as the result of an offer to purchase solicited by such Agent, as agent, the right to refuse to purchase and pay for such Securities if, at the Settlement Date for such Securities, any condition set forth in Section 6 hereof shall not have been satisfied (it being understood that the judgment of such person with respect to the impracticability or inadvisability of such purchase of Securities shall be substituted, for purposes of this Section 5(k), for the judgment of such Agent with respect thereto); and (l) To pay or cause to be paid the following: (i) the fees and expenses of the Company's counsel and accountants in connection with the registration of the Securities under the Act and all other expen- ses in connection with the preparation, printing and filing of the Registration Statement, any Preliminary Prospectus, the Prospectus and any Pricing Supplements and all other amendments and supplements thereto and the mailing and delivering of copies thereof to such Agent; (ii) the fees and expenses of counsel for the Agents in connection with the establishment of the program contemplated hereby, any opinions to be rendered by such counsel hereunder and the transactions contemplated hereunder; (iii) the cost of preparing this Agreement, any Terms Agreement and any other documents approved by the Company in connection with the offering, purchase, sale and delivery of the Securities; (iv) the fees, not to exceed $5,000, and expenses of counsel for the Agents in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(b) hereof and the preparation of any blue sky and legal investment memoranda;

provided, however, that, except as provided in Sections 8 and 9 hereof, such Agent shall pay all other expenses it incurs, including any expenses that may be incurred by it or for its account pursuant to the proviso of Section 5(c) hereof. 6. Conditions to Agents' Obligations. The obligation of an --------------------------------- Agent, as agent of the Company, at any time (each a "Solicitation Time"), to solicit offers to purchase the Securities and the obligation of an Agent to purchase Securities as principal, pursuant to a Terms Agreement or otherwise, shall be subject, in such Agent's discretion, to the conditions that: (i) all of the representations and warranties of the Company herein (and, in the case of an obligation of an Agent under a Terms Agreement or other agreement with an Agent to purchase Securities as principal, in or incorporated in such agreement by reference) were true and correct (A) on the Commencement Date; (B) each time that the Registration Statement or the Prospectus shall be amended or supplemented, (C) each time a document incorporated by reference in the Prospectus as amended or supplemented shall be filed by the Company under the Act or Exchange Act, (D) at the date of each acceptance by the Company of an offer to purchase Securities procured by such Agent, as agent, and each agreement by the Company, pursuant to a Terms Agreement or otherwise, to sell Securities to an Agent, as principal, (E) at each Settlement Date, and (F) at each Time of Delivery of Securities so to be purchased by such Agent, as principal, as the case may be, (ii) prior to such Solicitation Time or such Time of Delivery, as the case may be, the Company shall have performed all of its obligations hereunder theretofore to be performed, (iii) all requests for additional information on the part of the Commission shall have been complied with to the reasonable satisfaction of such Agent, (iv) there shall be in full force and effect orders of the Public Utility Commission of Oregon and the Washington Utilities and Transportation Commission which are acceptable to the Agents and which permit the issuance and sale of the Securities substantially in accordance with the terms and conditions of this Agreement, (v) no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall be pending before, or to the knowledge of the Company contemplated by, the Commission, and (vi) there shall not have occurred: (A) a suspension or material limitation of trading in securities generally on the New York Stock Exchange; (B) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities; (C) an engagement by the United States in hostilities or any escalation of hostilities, the effect of which, in the judgment of such Agent, makes it impracticable or inadvisable to proceed with the solicitation of offers to purchase Securities or the purchase of Securities from the Company as principal on the terms and in the manner contemplated by this Agreement and, if applicable, any Terms Agreement or other agreement; or (D) any downgrading, or any notice shall have been given of any intended or potential downgrading, of the Securities by either Moody's Investors Service or Standard & Poor's Corporation. In addition to the foregoing, the obligation of an Agent to purchase Securities as principal, pursuant to a Terms Agreement or other agreement, shall be subject, in such Agent's discretion, to the further condition that there shall not have been, since the date of such Terms Agreement or other agreement or since the respective dates as of which information is given in the Registration Statement, any 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. 7. Conditions to Company's Obligations. ------------------------------------ (a) The obligation of the Company to sell and deliver any Security pursuant hereto, to a Terms Agreement or otherwise shall be subject to the condition that, after the acceptance by the Company of an offer to purchase such Security procured by an Agent, as agent, or the agreement by the Company, pursuant to a Terms Agreement or otherwise, to sell such Security to an Agent, as principal, and prior to the Time of Delivery or the Settlement Date, as the case may be, with respect to such purchase or sale, neither the Public Utility Commission of Oregon nor the Washington Utilities and Transportation Commission shall have issued an order revoking its then existing order permitting the issuance and sale of the Securities through each Agent, as agent, on the terms set forth herein or to each Agent, as principal, pursuant to a Terms Agreement or other agreement. (b) If the condition specified in Section 7(a) hereof shall not have been fulfilled, the obligation of the Company to sell Securities hereunder or under a Terms Agreement or other agreement may be terminated by the Company; and neither the Company nor any Agent shall have any liability to the other, except for (i) the obligation of the Company to pay certain expenses to the extent provided for in Section 5(l) hereof, (ii) the obligation of the Company to pay commissions and hold the Agents harmless as provided in Section 9 hereof (and, for purposes of said Section 9, such a failure of such condition to be fulfilled shall be considered a default by the Company on its obligation to deliver such Securities), and (iii) any liability under Section 8 hereof. 8. Indemnification. --------------- (a) The Company will indemnify and hold harmless each Agent against any losses, claims, damages or liabilities, joint or several, to which such Agent may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or the Prospectus as amended or supplemented, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse such Agent for any legal or other expenses reasonably incurred by it, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall -------- ------- not be liable in any such case to the extent that any such loss, claim, damage or liability or action in respect thereof arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus or the Prospectus as amended or supplemented in reliance upon and in conformity with written information furnished to the Company by such Agent specifically for use therein; and provided, further, that the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of any Agent on account of any losses, claims, damages or liabilities or actions in respect thereof arising solely from the sale of Securities by or through such Agent pursuant to a Terms Agreement or otherwise to any person if a copy of the Prospectus as then amended and supplemented with respect to such Securities shall not have been sent or given to such person with or prior to written confirmation of the sale involved (assuming that the Company shall have previously furnished such documents to such Agent in a timely fashion), and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities. (b) Each Agent will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or the Pros- pectus as amended or supplemented, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 the Registration Statement, any Preliminary Prospectus, the Prospectus or the Prospectus as amended or supplemented in reliance upon and in conformity with written information furnished to the Company by such Agent specifically for use therein, and will reimburse the Company for any legal or other expenses incurred by the Company, as incurred, in connection with investigating or defending any such loss, claim, damage or liability or action. Each Agent hereby furnishes to the Company in writing expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented (i) the second sentence in the last paragraph on the cover page of the Prospectus relating to the offerings of Medium-Term Notes by the Agents, as principal, (ii) the legend on the inside cover page relating to stabilizing transactions by the Agents, and (iii) under "Plan of Distribution," the fourth and seventh sentences in the first paragraph, the second and last sentences of the fourth paragraph, the seventh paragraph and the eighth paragraph. (c) Promptly after receipt by an indemnified party under Section 8(a) or Section 8(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such Section. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemni- fied party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party); provided, however, in no -------- ------- event shall such indemnifying parties be obligated to retain more than one counsel (and necessary local counsel), in addition to counsel for such indemnifying parties, to represent the indemnified parties, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such Section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Each indemnified party may also participate at its own expense in the defense of any such action. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. (d) If the indemnification provided for in Section 8(a) or Section 8(b) hereof is unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect any relevant equitable considerations including the relative fault of the Company on the one hand and each Agent on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), and relative benefit of the Company on the one hand and each Agent on the other. 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 required to be stated therein or necessary in order to make the statements therein not misleading relates to information supplied by the Company on the one hand or by any Agent on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The relative benefits received by the Company on the one hand and each Agent on the other shall be deemed to be in the same proportion as the total net proceeds from the sale of Securities (before deducting expenses) received by the Company bear to the total commissions or discounts received by such Agent in respect thereof. The Company and each Agent agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined (i) with respect only to any losses, claims, damages or liabilities referred to in Section 8(a) hereof, by per capita allocation (even if all Agents were treated as one entity for such purpose) or (ii) by any method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. 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 obligations of each of the Agents under this Section 8(d) to contribute are several and are not joint. (e) The obligations of the Company under this Section 8 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 Agent within the meaning of the Act. The obligations of each Agent under this Section 8 shall be in addition to any liability which such Agent may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act. 9. Nonperformance. Each Agent, in soliciting offers to -------------- purchase Securities from the Company and in performing the other obligations of such Agent hereunder (other than in respect of any purchase by an Agent as principal pursuant to a Terms Agreement or otherwise), is acting solely as agent for the Company and not as principal. Each Agent will make reasonable efforts to assist the Company in obtaining performance by each purchaser whose offer to purchase Securities from the Company was solicited by such Agent and has been accepted by the Company, but such Agent shall not have any liability to the Company in the event such purchase is not consummated for any reason. If the Company shall default on its obligation to deliver Securities to a purchaser whose offer it has accepted, the Company shall (i) hold each Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) notwithstanding such default, pay to the Agent that solicited such offer any commission to which it would be entitled in connection with such sale. 10. Survival of Agreement. The respective indemnities, --------------------- agreements, representations, warranties and other statements by any Agent and the Company set forth in or made pursuant to this Agreement shall remain in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Agent or any controlling person of any Agent or the Company, or any officer or director or any controlling person of the Company, and shall survive each delivery of and payment for any of the Securities. 11. Suspension or Termination. The provisions of this Agreement ------------------------- relating to the solicitation of offers to purchase Securities from the Company may be suspended or terminated at any time by the Company as to any Agent or by any Agent as to such Agent upon the giving of written notice of such suspension or termination to such Agent or the Company, as the case may be. In the event of such suspension or termination with respect to any Agent, this Agreement shall remain in full force and effect with respect to (i) any Agent as to which such suspension or termination has not occurred, (ii) the rights and obligations of any party which have previously accrued or which relate to Securities which are already issued, agreed to be issued or the subject of a pending offer at the time of such suspension or termination, (iii) Sections 2(e), 5(d), 5(e), 5(l), 8, 9 and 10 hereof, and (iv) the obligations of the Company to amend or supplement the Prospectus, so long as any Agent continues to hold Securities as principal. 12.

The order dated February 4, 1997 of the Public Utility Commission of Oregon (the "OPUC") provides, among other things, that the authority contained therein is valid so long as the Company's senior debt securities maintain investment grade bond ratings from at least two nationally recognized statistical rating organizations. The order dated January 22, 1997 of the Washington Utilities and Transportation Commission (the "WUTC") confirms that the Company is authorized to issue and sell the Securities. In addition, such order of the OPUC authorizes, and such order of the WUTC confirms the authorization of, the issuance and sale by the Company only of Securities bearing interest at fixed rates, established within the maximum all-in spreads over Benchmark Treasury Yields for various maturities (determined in accordance with said orders as of the time the commitment to purchase any Securities is received by the Company and the Agent). As stated in the Company's Prospectus dated , 1997, if -------- the terms of any Security, as determined by the Company, provide that such Security will be redeemable at the option of the company, such Security will be made redeemable in whole or in part. Procedure for Rate Changes: -------------------------- When a decision has been reached to change the interest rate on or other variable terms with respect to any Securities being offered for sale, the Company will promptly advise the Agents and the Agents will forthwith suspend solicitation of offers to purchase such Securities. The Agent will telephone the Company with recommendations as to the changed interest rates or other variable terms. At such time as the Company advises the Agents of the new interest rates or other variable terms, the Agent may resume solicitation of offers to purchase such Securities. Until such time only "indications of interest" may be recorded. Acceptance or Rejection of Offers by Company: -------------------------------------------- Each Agent will promptly advise the Company by telephone or other appropriate means of all reasonable offers to purchase Securities, other than those rejected by such Agent. Each Agent, in its discretion reasonably exercised, may reject any offer received by it, in whole or in part. Each Agent also may make offers to the Company to purchase Securities as a Purchasing Agent. The Company, in its sole discretion, may accept any offer to purchase Securities and may reject any such offer, in whole or in part. The Company will promptly notify the Selling Agent or Purchasing Agent, as the case may be, of its acceptance or rejection of an offer to purchase Securities. If the Company accepts an offer to purchase Securities, it will confirm such acceptance in writing to the Selling Agent or Purchasing Agent, as the case may be. The order dated February 4, 1997 of the OPUC requires that, for each issuance of Securities, the Company seek and report to the OPUC at least one other bid quote in addition to the bid that is accepted. Settlement: ---------- The receipt of immediately available funds by the Company in payment for a Security and the authentication and delivery of such Security will, with respect to such Security, constitute "Settlement." All offers solicited by a Selling Agent or made by a Purchasing Agent and accepted by the Company will be settled on a date (the "Settlement Date") which shall be the third business day after the date of acceptance of such offer, unless the Company and the purchaser shall agree to settle (a) on any other business day after the acceptance of such offer or (b) with respect to an offer accepted by the Company prior to 10:00 a.m., New York City time, on the date of such acceptance. Settlement Procedures: --------------------- A.

If an identical Pricing Supplement has not been Previously filed with the Securities and Exchange Commission (the "SEC"), the Company will arrange to have transmitted promptly via EDGAR one copy of the Pricing Supplement (with the appropriate paragraph under Rule 424(b) and the Registration No. inscribed in the upper right corner) to the SEC, within the applicable time period provided in Rule 424(b).

Upon receipt of such instructions, the Agents will forthwith suspend solicitation of offers to purchase from the Company until such time as the Company has advised them that solicitation of offers to purchase may be resumed. If the Company decides to amend or supplement the Prospectus (other than to change interest rates or other variable terms with respect to the offering of the Securities), it will promptly advise the Agents and will furnish the Agents and their counsel with copies of the proposed amendment or supplement. In the event that at the time the solicitation of offers to purchase from the Company is suspended (other than to change interest rates or other variable terms) there shall be any orders outstanding which have not been settled, the Company will promptly advise the Agents and the Trustee whether such orders may be settled and whether copies of the Prospectus as theretofore amended and/or supplemented as in effect at the time of the suspension may be delivered in connection with the settlement of such orders. The Company will have the sole responsibility for such decision and for any arrangements which may be made in the event that the Company determines that such orders may not be settled or that copies of such Prospectus may not be so delivered. Delivery of Confirmation and Prospectus to Purchaser by Selling --------------------------------------------------------------- Agent: ----- The Selling Agent will deliver to the purchaser of a Security a written confirmation of the sale and delivery and Payment instructions.

K. The Agent will confirm the purchase of such Security to the purchaser either by transmitting to the Participant with respect to such Security a confirmation order through DTC's Participant Terminal System or by mailing a written confirmation to such purchaser. L. Settlement Procedures Timetable: (1) For orders of Securities accepted by the Company, Settlement Procedures A through K shall be completed as soon as possible but not later than the respective times (New York City time) set forth below: Settlement Procedure Time --------- ---- A 11:00 a.m. on the trade date B 2:00 p.m. on the trade date C 3:00 p.m. on the Business Day before Settlement Date D 9:00 a.m. on Settlement Date E 10:00 a.m. on Settlement Date F-G No later than 2:00 p.m. on Settlement Date H 4:45 p.m. on Settlement Date I-K 5:00 p.m. on Settlement Date (2) If a sale is to be settled more than one Business Day after sale date, Settlement Procedures A and B may, if necessary, be completed at any time prior to the specified times on the first Business Day after such sale date. In connection with a sale which is to be settled more than one Business Day after the trade date, if the initial interest rate for a Floating Rate Security is not known at the time that the Sale Information is given by the Presenting Agent to the Company, Settlement Procedures A and B shall be completed as soon as such rates have been determined, but no later than 11:00 a.m. and 2:00 p.m., New York City time, respectively, on the second Business Day before the Settlement Date. Settlement Procedure H is subject to extension in accordance with any extension of Fedwire closing deadlines and in the other events specified in the SDFS operating procedures in effect on the Settlement Date. (3) If settlement of a Security issued in book-entry form is rescheduled or canceled, the Trustee will deliver to DTC, through DTC's Participant Terminal System, a cancellation message to such effect by no later than 2:00 p.m., New York City time, on the Business Day immediately preceding the scheduled Settlement Date. Failure of Purchaser to Pay Selling Agent: ----------------------------------------- Certificated Securities ----------------------- If a purchaser shall fail to make payment to the Selling Agent for any Security, the net proceeds to the Company which, theretofore, shall have been paid by the Selling Agent to the Company, the Selling Agent will promptly notify the Mortgage Trustee or the Indenture Trustee, as the case may be, and the Company of such failure by telephone, promptly confirmed in writing or by facsimile transmission or by other acceptable written means. The Selling Agent promptly will return such Security to such Trustee. Promptly upon receipt of such Security by such Trustee, the Company will return to the Selling Agent an amount equal to the amount previously paid to the Company in respect of such Security. Such Trustee will cancel any Security in respect of which such a failure shall occur, make appropriate entries in its records and, unless otherwise instructed by the Company, destroy such Security. Book-Entry Securities --------------------- If the Trustee fails to enter an SDFS deliver order with respect to a Book-Entry Security issued in book-entry form pursuant to paragraph F above, the Trustee may deliver to DTC, through DTC's Participant Terminal System, as soon as practicable a withdrawal message instructing DTC to debit such Security to the participant account of the Trustee maintained at DTC. DTC will process the withdrawal message, provided that such participant account contains a principal amount of the Book-Entry Security representing such Security that is at least equal to the principal amount to be debited. If withdrawal messages are processed with respect to all the Securities represented by a Book-Entry Security, the Trustee will mark such Book-Entry Security "canceled", make appropriate entries in its records and send such canceled Book-Entry Security to the Company. The CUSIP number assigned to such Book-Entry Security shall, in accordance with CUSIP Service Bureau procedures, be canceled and not immediately reassigned. If withdrawal messages are processed with respect to a portion of the Securities represented by a Book-Entry Security, the Trustee will exchange such Book-Entry Security for two Book-Entry Securities, one of which shall represent the Book-Entry Securities for which withdrawal messages are processed and shall be canceled immediately after issuance, and the other of which shall represent the other Securities previously represented by the surrendered Book-Entry Security and shall bear the CUSIP number of the surrendered Book-Entry Security. If the purchase price for any Book-Entry Security is not timely paid to the Participants with respect to such Security by the beneficial purchaser thereof (or a person, including an indirect participant in DTC acting on behalf of such purchaser), such Participants and, in turn, the related Agent may enter SDFS deliver orders through DTC's Participant Terminal System reversing the orders entered pursuant to paragraphs F and G above, respectively. Thereafter, the Trustee will deliver the withdrawal message and take the related actions described in the preceding paragraph. If such failure shall have occurred for any reason other than default by the applicable Agent to perform its obligations hereunder or under the Distribution Agreement, the Company will reimburse such Agent on an equitable basis for its loss of the use of funds during the period when the funds were credited to the account of the Company. Notwithstanding the foregoing, upon any failure to settle with respect to a Book-Entry Security, DTC may take any actions in accordance with its SDFS operating procedures then in effect. In the event of a failure to settle with respect to a Security that was to have been represented by a Book-Entry Security also representing other Securities, the Trustee will provide, in accordance with paragraphs C and D above, for the authentication and issuance of a Book-Entry Security representing such remaining Securities and will make appropriate entries in its records.

The Mortgage and the Indenture have been duly and validly authorized by all necessary corporate action, have been duly and validly executed and delivered, and are valid and binding instruments enforceable in accordance with their terms, subject, as to enforcement, to laws and principles of equity relating to or affecting generally the enforcement of creditors rights, including, without limitation, bankruptcy and insolvency. 5. The Company has good and sufficient title to all the properties described in, and as subject to the lien of, the Mortgage and now owned by it, subject only to excepted encumbrances as defined in the Mortgage and to minor defects and irregularities customarily found in properties of like size and character, which, in my opinion, do not materially impair the use of the property affected thereby in the operation of the business of the Company; the description in the Mortgage of such properties is adequate to constitute the Mortgage a lien thereon; and the Mortgage constitutes a valid, direct first mortgage lien on such properties, which include substantially all of the permanent physical properties and franchises of the Company (other than those expressly excepted), subject only to the exceptions enumerated above in this paragraph. 6. The form of the Secured Notes has been duly authorized and has been established in conformity with the provisions of the Mortgage; the form of the Unsecured Notes bearing interest at a fixed rate, has been duly authorized and has been established in conformity with the provisions of the Indenture; and the form of the Unsecured Notes, bearing interest at a variable rate or not bearing interest, when set forth in a Company Order or Orders or established by procedures acceptable to the Indenture Trustee specified in a Company Order or Orders, will have been duly authorized and will have been established in conformity with the provisions of the Indenture. 7. The Secured Notes have been duly authorized by the resolutions adopted by the Board of Directors on May 27, 1993, September 26, 1996 and April 24, 1997 (the "Board Resolutions"), and when the terms of the Secured Notes shall have been determined as contemplated by and in accordance with the Mortgage, the Board Resolutions and written orders or instructions evidencing determinations by Officers of the Company, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Mortgage. 8. The Unsecured Notes have been duly authorized by the Board Resolutions, and when the terms of the Unsecured Notes shall have been determined as contemplated by and in accordance with the Indenture, the Board Resolutions and, to the extent required by the Indenture and the Board Resolutions, by Officers' Certificates, Company Orders (each, as defined in the Indenture) and procedures acceptable to the Indenture Trustee specified in such Company Orders, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Indenture. 9. The Notes, when (a) executed by the Company, (b) completed, authenticated and delivered by the Corporate Trustee or the Indenture Trustee, as the case may be, (c) issued and delivered by the Company and (d) paid for, all as contemplated by and in accordance with the Mortgage, in the case of Secured Notes, the Indenture, in the case of Unsecured Notes, the Board Resolutions, and (to the extent required by the Mortgage or the Indenture and the Board Resolutions) Officers' Certificates, Company Orders, procedures acceptable to the Indenture Trustee specified in such Company Orders, written orders or instructions evidencing determinations by the officers of the Company, the Agreement, the Administrative Procedure (as defined in the Agreement), and Terms Agreements (as defined in the Agreement), if any, will be duly issued under the Mortgage or the Indenture, as the case may be, and will constitute valid and legally binding obligations of the Company, entitled to the benefits provided by the Mortgage or the Indenture, as the case may be, and enforceable in accordance with their terms, subject, as to enforcement, to laws and principles of equity relating to or affecting generally the enforcement of creditors' rights, including, without limitation, bankruptcy and insolvency, and, in the case of the Secured Notes, entitled to the benefit of the security afforded by the Mortgage. 10. The issuance and sale of the Notes, the compliance by the Company with all of the provisions of the Notes, the Mortgage, the Indenture and the Agreement and the consummation of the transactions contemplated by the Agreement will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any statute, any indenture, mortgage, deed of trust or other agreement or instrument known to me to which the Company is a party or by which it is bound or to which any of the property of the Company is subject, the Company's Restated Articles of Incorporation, as amended, or Bylaws, as amended, or any order, rule or regulation known to me of any court or governmental agency or body having jurisdiction over the Company or any of its properties. 11. The OPUC and the WUTC have issued orders authorizing the issuance and sale by the Company of the Notes; and no further approval, authorization, consent or other order of any public board or body (other than in connection or in compliance with the provisions of the securities or blue sky laws of any jurisdiction) is legally required for the issuance and sale of the Notes through each of you, as agent, on the terms and conditions set forth in the Agreement. 12. The statements of Oregon, Washington and Federal law (other than the 1933 Act, the Securities Exchange Act of 1934 and the Trust Indenture Act), and legal conclusions based thereon, contained in, or in the documents incorporated by reference in, the Prospectus have been reviewed by me and are correct (except to the extent that any statement contained in a document incorporated or deemed to be incorporated by reference in the Prospectus may be deemed to be modified or superseded in the Prospectus or in any other subsequently filed document which also is or is deemed to be incorporated by reference in the Prospectus). 13. Except as described in the Prospectus, there are no pending material legal or governmental proceedings and, to my knowledge, no material threatened legal or governmental proceedings, to which the Company is a party or of which any of the property of the Company is subject, other than ordinary routine litigation incidental to the kind of business conducted by the Company. In the course of the preparation by the Company of the Initial and the Subsequent Registration Statements and the Prospectus, I had conferences with certain officers and employees of the Company, but I have made no independent verification of the accuracy or completeness of the representations and statements made to me by such person or the information included by the Company in either of such Registration Statements and the Prospectus, and take no responsibility therefor, except as forth in paragraph 12 hereof. However, my examination of such Registration Statements and the Prospectus and my discussions in the above-mentioned conferences did not disclose to me any information which gives me reason to believe that, when each of the Initial and Subsequent Registration Statements became effective, it 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, as of the date of this opinion, the Prospectus includes an untrue statement of a material fact 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; provided, that I do not express any belief as to the financial statements or other financial or statistical data contained in such Registration Statements or the Prospectus, or as to the Forms T-1 or T-2, or as to any information contained therein furnished to the Company in writing by any of you expressly for use therein. This opinion is limited to the facts and law at the date hereof. In rendering the opinions set forth in paragraphs 9, 10 and 11 above, I have necessarily assumed that, at the time of any issuance, sale and delivery of a Note (i) the Board of Directors of the Company (or any committee thereof acting pursuant to authority properly delegated to such committee by the Board of Directors) has not taken any action to rescind or otherwise reduce its prior authorization of the issuance of the Notes and an officer of the Company, as stated in the resolutions of the Board of Directors (or any such committee) relating to the Notes, has executed and delivered such Notes, (ii) the orders of the OPUC and the WUTC with respect to the Notes remain in full force and effect and have not been modified or amended by the OPUC or the WUTC, respectively, and the Company complies with the terms of such orders and (iii) the orders of the SEC with respect to the Initial Registration Statement, the Subsequent Registration Statement, the Mortgage and the Indenture remain in full force and effect and have not been modified or amended by the SEC. I am a member of the bar of the States of Oregon and Washington and do not hold myself out as an expert on the laws of the State of New York or Federal securities laws. Accordingly, in rendering this opinion, I have relied, with your consent, as to all matters governed by the laws of the State of New York, the 1933 Act, the Securities Exchange Act of 1934 and the Trust Indenture Act, upon the opinion of even date herewith addressed to you by Reid & Priest LLP, New York, New York, counsel for the Company. I have read such opinion and concur in the conclusions expressed therein insofar as such conclusions involve questions of Oregon and Washington law. You, the Trustees and, as to matters governed by the laws of the State of Oregon and the State of Washington, Reid & Priest LLP and your counsel may rely upon this opinion in connection with the issuance and sale of the Notes. Neither you nor any of them may rely upon this opinion for any other purpose, and no other person may rely upon this opinion for any purpose without, in each case, my prior written consent. Very truly yours, Bruce B. Samson, Esq. A N N E X I V , 1997 ----------- Merrill Lynch & Co.

We have also examined such other documents and satisfied ourselves as to such other matters as we have deemed necessary in order to render this opinion. We have not examined the Notes, except specimens thereof. In the preparation of this opinion, we have examined originals or photostatic or certified copies of such certificates, agreements, documents and other papers, and have made such inquiries and investigations of law, as we deemed appropriate and necessary for the opinion hereinafter set forth. In our examination, we have assumed the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents. As to certain matters of fact material to the opinion expressed herein, we have relied upon certificates of various corporate officers of the Company and public officials. We assume the accuracy of the material and factual matters contained therein. We are of the opinion that: 1. The Company is a validly organized and existing corporation in good standing under the laws of the State Of Oregon, and is qualified to do business and is in good standing in the State of Washington. 2. The Agreement has been duly and validly authorized, executed and delivered by the Company. 3. The Mortgage and the Indenture have been duly and validly authorized by all necessary corporate action, have been duly and validly executed and delivered, have been duly qualified under the Trust Indenture Act, and are valid and binding instruments enforceable in accordance with their terms, subject, as to enforcement, to laws and principles of equity relating to or affecting generally the enforcement of creditors' rights, including, without limitation, bankruptcy and insolvency. 4. The form of the Secured Notes has been duly authorized and has been established in conformity with the provisions of the Mortgage and conforms to the description thereof contained in the Prospectus; the form of the Unsecured Notes, bearing interest at a fixed rate, has been duly authorized and has been established in conformity with the provisions of the Indenture and conforms to the description thereof contained in the Prospectus; and the form of the Unsecured Notes, bearing interest at a variable rate or not bearing interest, when set forth in a Company Order or Orders or established by procedures acceptable to the Indenture Trustee specified in a Company Order or Orders, will have been duly authorized and will have been established in conformity with the provisions of the Indenture. 5. The Secured Notes have been duly authorized by the resolutions adopted by the Board of Directors on May 27, 1993, September 26, 1996 and April 24, 1997 (the "Board Resolutions"), and when the terms of the Secured Notes shall have been determined as contemplated by and in accordance with the Mortgage, the Board Resolutions and written orders or instructions evidencing determinations by Officers of the Company, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Mortgage. 6. The Unsecured Notes have been duly authorized by the Board Resolutions, and when the terms of the Unsecured Notes shall have been determined as contemplated by and in accordance with the Indenture, the Board Resolutions and, to the extent required by the Indenture and the Board Resolutions, by Officers' Certificates, Company Orders (each, as defined in the Indenture) and procedures acceptable to the Indenture Trustee specified in such Company Orders, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Indenture. 7. The Notes, when (a) executed by the Company, (b) completed, authenticated and delivered by the Corporate Trustee or the Indenture Trustee, as the case may be, (c) issued and delivered by the Company and (d) paid for, all as contemplated by and in accordance with the Mortgage, in the case of the Secured Notes, the Indenture, in the case of Unsecured Notes, the Board Resolutions, and (to the extent required by the Mortgage or the Indenture and the Board Resolutions) Officers' Certificates, Company Orders, procedures acceptable to the Indenture Trustee specified in such Company Orders, written orders or instructions evidencing determinations by the officers of the Company, the Agreement, the Administrative Procedure (as defined in the Agreement) and Terms Agreements (as defined in the Agreement), if any, will be duly issued under the Mortgage or the Indenture, as the case may be, and will constitute valid and legally binding obligations of the Company, entitled to the benefits provided by the Mortgage or the Indenture, as the case may be, and enforceable in accordance with their terms, subject, as to enforcement, to laws and principles of equity relating to or affecting generally the enforcement of creditors' rights, including, without limitation, bankruptcy and insolvency, and, in the case of the Secured Notes, entitled to the benefit of the security afforded by the Mortgage. 8. The issuance and sale of the Notes, the compliance by the Company with all of the provisions of the Notes, the Mortgage, the Indenture and the Agreement and the consummation of the transactions contemplated by the Agreement will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, the Mortgage and the Indenture or the Company's Restated Articles of Incorporation, as amended, or Bylaws, as amended. 9. The OPUC and the WUTC have issued orders authorizing the issuance and sale by the Company of the Notes; and no further approval, authorization, consent or other order of any public board or body (other than in connection or in compliance with the provisions of the securities or blue sky laws of any jurisdiction) is legally required for the issuance and sale of the Notes through each of you, as agent, on the terms and conditions set forth in the Agreement. 10. Both the Initial and Subsequent Registration Statements have become effective under the Act, and, to the best of our knowledge, no stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose are pending before or have been proposed by the SEC; the Mortgage and the Indenture have been duly qualified under the Trust Indenture Act; each of the Initial and Subsequent Registration Statements at the time it became effective complied, and the Prospectus (excluding the documents incorporated therein by reference) as of the date of this opinion complies, as to form, in all material respects with the requirements of the Act, the Trust Indenture Act (except with respect to the Forms T-1 and Form T-2, upon which we do not pass) and the rules and regulations of the SEC thereunder; and the documents incorporated by refer- ence in the Prospectus pursuant to Item 12 of Form S-3 (other than the financial statements and other financial or statistical data contained therein, upon which we express no opinion), as of their respective dates of filing, complied as to form in all material respects with the requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations of the SEC thereunder. In the course of the preparation by the Company of the Initial and the Subsequent Registration Statements and the Prospectus, we had conferences with certain officers and employees of the Company, with the General Counsel for the Company and with you and your counsel, but we made no independent verification of the accuracy or completeness of the representations and statements made to us by such persons or the information included by the Company in either of such Registration Statements and the Prospectus and take no responsibility therefor, except insofar as set forth in paragraph 4 hereof. In passing upon the forms of such Registration Statements and the Prospectus we have, therefore, assumed the accuracy and completeness of such representations, statements and information, except as aforesaid. However, our examination of such Registration Statements and the Prospectus and our discussions in the above-mentioned conferences did not disclose to us any information which gives us reason to believe that, when each of the Initial and the Subsequent Registration Statements became effective, it 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, as of the date of this opinion, the Prospectus includes an untrue statement of a material fact 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; provided, that we do not express any belief as to the financial statements or other financial or statistical data contained in such Registration Statements or the Prospectus, or as to the Forms T-1 or T-2, or as to any information contained therein furnished to the Company in writing by any of you expressly for use therein. This opinion is limited to the facts and law at the date hereof. In rendering the opinions set forth in paragraphs 7 and 9 above, we have necessarily assumed that, at the time of any issuance, sale and delivery of a Note (i) the Board of Directors of the Company (or any committee thereof acting pursuant to authority properly delegated to such committee by the Board of Directors) has not taken any action to rescind or otherwise reduce its prior authorization of the issuance of the Notes and an officer of the Company, as stated in the resolutions of the Board of Directors (or any such committee) relating to the Notes, has executed and delivered such Notes, (ii) the orders of the OPUC and the WUTC with respect to the Notes remain in full force and effect and have not been modified or amended by the OPUC or the WUTC, respectively, and the Company complies with the terms of such orders and (iii) the orders of the SEC with respect to the Initial Registration Statement, the Subsequent Registration Statement, the Mortgage and the Indenture remain in full force and effect and have not been modified or amended by the SEC. We are members of the bar of the State of New York and do not hold ourselves out as experts on the laws of the State of Oregon or the State of Washington. Accordingly, in rendering this opinion, we have relied, with your consent, as to all matters governed by the laws of the State of Oregon and the State of Washington (including titles to property and franchises and the lien of the Mortgage, upon which we do not pass), upon the opinion of even date herewith addressed to you by Bruce B. Samson, Esq., General Counsel of the Company. We have read such opinion, which is in form satisfactory to us, and concur in the conclusions expressed therein insofar as such conclusions involve questions of the laws of the State of New York, the 1933 Act, the Exchange Act and the Trust Indenture Act. You, the Trustees, and as to matters governed by the laws of the State of New York and the 1933 Act, the Exchange Act and the Trust Indenture Act, Bruce B. Samson, Esq., may rely upon this opinion in connection with the issuance and sale of the Notes. Neither you nor any of them may rely upon this opinion for any other purpose, and no other person may rely upon this opinion for any purpose without, in each case, our prior written consent. Very truly yours, REID & PRIEST LLP ANNEX V [Contents of Letter of Independent Public Accountants] The letter of each independent public accountant will state in effect that, for the periods during which such firm was the independent public accountant for the Company: 1. They are independent public accountants with respect to the Company within the meaning of the Act and the applicable published Rules and Regulations; 2. In their opinion, the financial statements examined by them and incorporated by reference in the Registration Statement comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the published rules and regulations thereunder; 3. On the basis of limited procedures, not constituting an examination made in accordance with generally accepted auditing standards, including a reading of the latest available interim financial statements of the Company, if any, a reading of the minute books of the Company since December 31, 19__, inquiries of officials of the Company responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that: (a)(1) the latest interim consolidated financial statements included or incorporated by reference in the Registration Statement do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the published rules and regulations thereunder as they apply to Form 10-Q or (2) said interim consolidated financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited consolidated financial statements incorporated by reference in the Registration Statement; (b) at the date of the latest available interim balance sheet of the Company and at a subsequent specified date not more than five days prior to the Time of Delivery, there has been any change in the capital stock (except for (I) shares of the Company's Common Stock issued under the Company's Dividend Reinvestment Plan, 1985 Stock Option Plan or Employee Stock Purchase Plan, (II) shares of Common Stock issued upon the conversion of shares of the Company's Convertible Debentures, and (III) shares of Preferred Stock purchased or redeemed pursuant to or in anticipation of sinking and purchase funds with respect to the Company's Preferred Stock) or any increase in the long-term debt of the Company, or any decrease in net assets, in each case as compared with amounts shown in the balance sheet as of the date of the latest financial statements incorporated by reference in the Registration Statement, except in each case for changes, increases or decreases which the Registration Statement discloses have occurred or may occur, which were occasioned by the declaration of dividends or which are described in such letter; or (c) for the 12-month period for which the latest unaudited financial statements are available, there were any decreases, as compared with the latest 12-month period for which financial statements are incorporated by reference in the Prospectus, in operating revenues, net income and earnings available for common stock, except in each case for decreases which the Registration Statement discloses have occurred or may occur, which were occasioned by the declaration of dividends or which are described in such letter; and 4. They have performed certain other specified procedures with respect to certain amounts and percentages set forth in the Registration Statement or in the documents incorporated by reference therein, as have been requested by your counsel and approved by the Company, and have found them to be in agreement with the records of the Company and the computations to be arithmetically correct.
