        Dear Sirs:

                  Northwest Natural Gas Company, an Oregon corporation (the
        "Company"), proposes to issue and sell from time-to-time not to exceed
        $165,000,000 of its First Mortgage Bonds, designated Secured Medium-
        Term Notes, Series B (the "Secured Notes"), and its Unsecured Medium-
        Term Notes, Series B (the "Unsecured Notes", and, together with the
        Secured Notes, the "Securities").  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-
             ___________) (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 "Preliminary 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 there-
             under; 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, constitute 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; provided, however, that further
             authorization must be obtained by the Company under the public
             utility laws of the States of Oregon and Washington prior to any
             sale of any Security to an Agent, as principal;  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%

                  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 representations 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.

                       ------------------------
        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 disap-
             prove 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
             Prospectus, 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 de-
             finitive 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 suspen-
             sion 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

             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 juris-
             diction, or to comply with any other requirement reasonably
             deemed by the Company to be unduly burdensome;

                  (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 amendment
             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 Pro-
             spectus 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);

                  (d)  To make generally available to its security holders as
             soon as practicable, but in any event not later than eighteen
             months after (i) the effective date of the Registration

             amendment to the Registration Statement, and (iii) the date of
             each filing by the Company with the Commission of an Annual
             Report on Form 10-K that is incorporated by reference in the
             Registration Statement, an earning statement of the Company and
             its subsidiaries (which need not be audited) in accordance with
             Section 11(a) of the Act and the rules and regulations of the
             Commission thereunder (including, at the option of the Company,
             Rule 158);

                  (e)  For the period ending five years from the date any
             Securities are sold by the Company pursuant to an offer solicited
             by such Agent under this Agreement, to furnish to such Agent
             copies of all reports or other communications (financial or
             other) furnished to stockholders, and deliver to such Agent (i)
             as soon as they are available, copies of any reports and
             financial statements furnished to or filed with the Commission

             Act, (ii) copies of all registration statements filed under the
             Act (other than those in respect of shareholder or employee
             plans), and (iii) such additional information concerning the
             business and financial condition of the Company as such Agent may
             from time to time reasonably request (such financial statements
             to be on a consolidated basis to the extent the accounts of the
             Company and its subsidiaries are consolidated in reports
             furnished to its stockholders generally or to the Commission);

                  (f)  That, from the date of any Terms Agreement or other
             agreement with such Agent to purchase Securities as principal and
             to and including the earlier of (i) the termination of the
             trading restrictions for the Securities purchased thereunder, as
             notified to the Company by such Agent and (ii) the related Time
             of Delivery, the Company, without the prior written consent of
             such Agent, will not offer, sell, contract to sell or otherwise
             dispose of any debt securities of the Company in a public
             offering which both have a maturity of from nine months to 30
             years and are substantially similar to the Securities;

                  (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 repre-
             sentations and warranties shall be deemed to relate to the
             Registration Statement and the Prospectus as amended and
             supplemented relating to such Securities);

                  (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 supplemented to such
             date;

                  (i)  That each time that (x) the Registration Statement or
             the Prospectus shall be amended or supplemented (other than by a
             Pricing Supplement or by an amendment or supplement providing
             solely for a change in the interest rates of the Securities or
             similar changes and, unless the Agents shall otherwise specify,
             other than by an amendment or supplement which relates
             exclusively to an offering of debt securities other than the
             Securities), (y) a document incorporated by reference in the
             Prospectus as amended or supplemented (other than a Current
             Report on Form 8-K, unless the Agents shall otherwise specify)
             shall be filed under the Act or Exchange Act (unless waived by
             the Agents), and (z) 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 an opinion, letter or certificate under this Section
             5(i) as a condition to the purchase of Securities pursuant to
             such Terms Agreement or other agreement, the Company shall
             furnish or cause to be furnished to such Agent:

                       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(b) 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

                       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

                       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

                       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

                       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 a
             letter of Deloitte & Touche LLP or other independent accountants
             for the Company reasonably satisfactory to the 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 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

             Preliminary Prospectus, the Prospectus and any Pricing Supple-
             ments 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

             expenses have been approved by the Company; and (x) all other
             costs and expenses incident to the performance of the Company's
             obligations hereunder which are not otherwise specifically
             provided for in this Section; 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 Com-
        mencement 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 Solicita-
        tion 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 down-
        grading, 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 reli-
             ance 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 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, 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.

                  (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 indemnified 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 connec-
             tion 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.

                                                                       ANNEX I

                            Northwest Natural Gas Company

                               Administrative Procedure
                               ------------------------


                  This Administrative Procedure relates to the Securities
        defined in the Distribution Agreement, dated ___________, 1996 (the
        "Distribution Agreement"), amongst Northwest Natural Gas Company (the
        "Company"), on the one hand, and Merrill Lynch & Co., Merrill Lynch,
        Pierce, Fenner & Smith Incorporated, PaineWebber Incorporated, and
        each other person which shall become a party thereto (each, an "Agent"
        and, together, the "Agents"), on the other.  Defined terms used herein
        and not defined herein shall have the meanings given such terms in the
        Distribution Agreement or the Indentures.  An Agent, in relation to a
        purchase of a Security by a purchaser solicited by such Agent, is
        referred to herein as the "Selling Agent" and, in relation to a
        purchase of a Security by such Agent as principal other than pursuant
        to a Terms Agreement, as the "Purchasing Agent".  As used herein, the
        term "business day" shall mean any day when banks in New York City are
        not authorized or obligated by law or executive order to remain
        closed.

                  The procedures to be followed with respect to the settlement
        of sales of Securities directly by the Company to purchasers solicited
        by an Agent, as agent, are set forth below.  The terms and settlement
        details related to a purchase of Securities by an Agent, as principal,
        from the Company will be set forth in a Terms Agreement, pursuant to
        the Distribution Agreement, unless the Company and such Agent
        otherwise shall agree.

                  The Company will advise each Agent in writing of those
        persons with whom such Agent is to communicate regarding offers to
        purchase Securities and the related settlement details.

                  The order dated _________, 1996 of the Public Utility
        Commission of Oregon (the "OPUC") provides, among other things, that
        the authority contained therein is valid through _________, 199_, and
        the order dated ________, 1996 of the Washington Utilities and
        Transportation Commission (the "WUTC") provides that the Company is
        authorized to issue and sell Securities not later than ________, 199_. 
        In addition, such orders of the OPUC and the WUTC authorize 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 November __,
        1996, 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. 

                  Further authorization must be obtained under the public
        utility laws of the States of Oregon and Washington prior to any sale
        of any Security to any Agent, as principal.

        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 _________, 1996 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.   After the acceptance of an offer by the Company, the Selling
        Agent or Purchasing Agent, as the case may be, will communicate the

                  reoffering price);

             (3)  Selling Agent's commission or, if applicable, Purchasing

        Suspension of Solicitation; Amendment or Settlement:
        ---------------------------------------------------

                  Subject to its representations, warranties and covenants
        contained in the Distribution Agreement, the Company may instruct the
        Agents to suspend solicitation of purchases at any time.  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

        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.

        or Purchasing Agent, as the case may be, the Company will communicate
        such Sale Information to the Mortgage Trustee or the Indenture
        Trustee, as the case may be, by telephone (confirmed in writing, by

                  The Company will instruct such Trustee by telephone

        acceptable written means) to authenticate and deliver the Securities

        Procedures for Book-Entry Securities:

                  In connection with Securities issued in book-entry form and
        maintained in the book-entry system of The Depository Trust Company
        ("DTC"), (i) the Company and the Trustee shall act in accordance with
        the letters of representation (relating to the Secured Notes and the
        Unsecured Notes, respectively) from the Company and the Trustee to
        DTC, as the same may be amended, supplemented or otherwise modified
        from time to time, and (ii) the Trustee shall act in accordance with
        one or more Medium-Term Note Certificate Agreements, relating to the
        Securities, between the Trustee and DTC, as the same may be amended,
        supplemented or otherwise modified from time to time, and in
        accordance with its obligations as a participant in DTC.

                  The beneficial owner of a Security issued in book-entry form
        (or one or more indirect participants in DTC designated by such owner)
        will designate one or more participants in DTC (with respect to such
        Security issued in book-entry form, the "Participants") to act as
        agent for such beneficial owner in connection with the book-entry
        system maintained by DTC, and DTC will record in book-entry form, in
        accordance with instructions provided by such Participants, a credit
        balance with respect to such Security issued in book-entry form in the
        account of such Participants.  The ownership interest of such
        beneficial owner in such Security issued in book-entry form will be
        recorded through the records of such Participants or through the
        separate records of such Participants and one or more indirect
        participants in DTC.

                  Transfers of a Book-Entry Security will be accomplished by
        book entries made by DTC and, in turn, by Participants (and in certain
        cases, one or more indirect participants in DTC) acting on behalf of
        beneficial transferors and transferees of such Book-Entry Security.

                  Beneficial interests in the Securities may be purchased,
        owned and transferred only in denominations of $1,000 or any integral
        multiple of $1,000.

        maintained by DTC and (ii) to debit the settlement accounts of such
        Participants and credit the settlement account of the Presenting Agent
        maintained by DTC, in an amount equal to the initial public offering
        price of such Security.

             H.   Transfer of funds in accordance with SDFS deliver orders
        described in Settlement Procedures F and G will be settled in
        accordance with SDFS operating procedures in effect on the Settlement
        Date.

             I.   The Trustee will credit to an account of the Company
        maintained at the Trustee funds available for immediate use in the
        amount transferred to the Trustee in accordance with Settlement
        Procedure F.

             J.   The Trustee will send a copy of the Book-Entry Security by
        first class mail to the Company together with a statement setting
        forth the principal amount of Securities Outstanding as of the related
        Settlement Date after giving effect to such transaction and all other
        offers to purchase Securities of which the Company has advised the
        Trustee but which have not yet been settled.

             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.

                       soon as possible but not later than the respective
                       times (New York City time) set forth below:

                       Settlement
                       Procedure                     Time
                       ---------                     ----

                          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

                                      Date
                          F-G         No later than 2:00 p.m. on
                                      Settlement Date

                                      Date
                          I-K         5:00 p.m. on Settlement

                  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 of 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.

                  With reference to the issuance and sale from time-to-time by

        between the Company and each of you, of not to exceed $165,000,000 in

        designated Secured Medium-Term Notes, Series B (the "Secured Notes")
        to be issued under the Company's Mortgage and Deed of Trust, dated as
        of July 1, 1946, to Bankers Trust Company (the "Corporate Trustee")
        and R.G. Page (Stanley Burg, successor), as trustees, as supplemented
        by twenty supplemental indentures (such Mortgage and Deed of Trust, as
        so supplemented, being hereinafter called the "Mortgage"), and (ii)
        the Company's Unsecured Medium-Term Notes, Series B  (the "Unsecured
        Notes"), to be issued under the Company's Indenture, dated as of June
        1, 1991 (the "Indenture"), to Bankers Trust Company, as trustee (the
        "Indenture Trustee") (the Secured Notes and the Unsecured Notes being
        hereinafter collectively referred to as the "Notes"), and the
        appointment of each of you as agents of the Company pursuant to the
        Agreement for the purposes  of soliciting and receiving offers to
        purchase Notes, as agents, and purchasing Notes, as principals, from
        the Company, please be advised that, as General Counsel of the
        Company, I have participated in the preparation of or reviewed (a) the
        Restated Articles of Incorporation, as amended, and Bylaws, as
        amended, of the Company; (b) the Mortgage; (c) the Indenture; (d) the
        Agreement; (e) the registration statement (File No. 33-64014) (the
        "Initial Registration Statement"), filed by the Company with the
        Securities and Exchange Commission (the "SEC") for the registration
        under the Securities Act of 1933, as amended (the "1933 Act"), of
        $150,000,000 of the Notes, of which $15,000,000 remain unsold, and for
        the qualification under the Trust Indenture Act of 1939, as amended
        (the "Trust Indenture Act"), of the Mortgage and the Indenture, which
        Initial Registration Statement became effective on June 17, 1993; (f)
        the registration statement (File No. 333-_______) (the "Subsequent
        Registration Statement"), filed by the Company with the SEC for the
        registration under the 1933 Act of an additional $150,000,000 of the
        Notes, and for the qualification under the Trust Indenture Act of the
        Mortgage and the Indenture, which Subsequent Registration Statement
        became effective on __________, 1996; (g) the combined prospectus
        relating to the Notes constituting a part of the Subsequent
        Registration Statement in the form in which it became effective, or if
        amended or supplemented subsequent to such effectiveness, as so
        amended and supplemented, including the documents incorporated therein
        by reference pursuant to Item 12 of Form S-3 (the "Prospectus"); (h)
        the proceedings before the Public Utility Commission of Oregon and the
        Washington Utilities and Transportation Commission relating to the
        issuance and sale of the Notes; and (i) the records of various
        corporate and other proceedings relating to the authorization,
        issuance and sale of the Notes.  I have also examined such other
        documents and satisfied myself as to such other matters as I have
        deemed necessary in order to render this opinion.  I have not examined
        the Notes, except specimens thereof.

                  In preparation of this opinion, I have examined originals or
        photostatic certified copies of such certificates, agreements,
        documents and other papers, and have made such inquiries and
        investigations of law, as I deemed appropriate and necessary for the
        opinion hereinafter set forth.  In my examination, I have assumed the
        authenticity of all documents submitted to me 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, I have relied upon certificates of various
        corporate officers of the Company and public officials. I assume the
        accuracy of the material and  factual matters contained therein.

                  I am 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, is qualified to do business and is in good standing in
             the State of Washington, and has power (corporate and other) to
             own its properties and conduct its business as described in  the
             Prospectus.

                  2.   The Company holds valid and subsisting franchises,
             licenses, permits and consents, free from burdensome restrictions
             and adequate for the conduct of its business, as and to the
             extent set forth in the Prospectus.

                  3.   The Agreement has been duly and validly authorized,
             executed and delivered by the Company.

                  4.   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,
             and September 26, 1996 (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; provided, however, that
             further authorization must be obtained by the Company under the
             public utility laws of the States of Oregon and Washington prior
             to any sale of any Note by the Company to either of you, as
             principal.

                  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; provided, however, that
             further authorization must be obtained by the Company under the
             public utility laws of the States of Oregon and Washington prior
             to any sale of any Note by the Company to either of you, as
             principal.

                  11.  The Public Utility Commission of Oregon and the
             Washington Utilities and Transportation Commission 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.

                  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.

        Dear Sirs:

                  With reference to the issuance and sale from time-to-time by

        and R.G. Page (Stanley Burg, successor), as trustees, as supplemented
        by twenty supplemental indentures (such Mortgage and Deed of Trust, as
        so supplemented, being hereinafter called the "Mortgage"), and (ii)
        the Company's Unsecured Medium-Term Notes, Series B (the "Unsecured
        Notes"), to be issued under the Company's Indenture, dated as of June
        1, 1991 (the "Indenture"), to Bankers Trust Company, as trustee (the
        "Indenture Trustee") (the Secured Notes and the Unsecured Notes being
        hereinafter collectively referred to as the "Notes"), and the
        appointment of each of you as agents of the Company pursuant to the
        Agreement for the purposes of  soliciting and receiving offers to
        purchase Notes, as agents, and purchasing Notes, as principals, from
        the Company, please be advised that, as counsel to the Company, we
        have participated in the preparation of or reviewed (a) the Restated
        Articles of Incorporation, as amended, and Bylaws, as amended, of the
        Company; (b) the Mortgage; (c) the Indenture; (d) the Agreement; (e)
        the registration statement (File No. 33-64014) (the "Initial
        Registration Statement"), filed by the Company with the Securities and
        Exchange Commission (the "SEC") for the registration under the
        Securities Act of 1933, as amended (the "1933 Act"), of $150,000,000
        of the Notes, of which $15,000,000 remain unsold, and for the
        qualification under the Trust Indenture Act of 1939, as amended (the
        "Trust Indenture Act"), of the Mortgage and the Indenture, which
        Initial Registration Statement became effective on June 17, 1993; (f)
        the registration statement (File No. 333-_______) (the "Subsequent
        Registration Statement"), filed by the Company with the SEC for the
        registration under the 1933 Act of an additional $150,000,000 of the
        Notes, and for the qualification under the Trust Indenture Act of the
        Mortgage and the Indenture, which Subsequent Registration Statement
        became effective on ___________, 1996; (g) the combined prospectus
        relating to the Notes constituting a part of the Subsequent
        Registration Statement in the form in which it became effective, or if
        amended or supplemented subsequent to such effectiveness, as so
        amended or supplemented, including the documents incorporated therein
        by reference pursuant to Item 12 of Form S-3 (the "Prospectus"); (h)
        the records of the proceedings before the Public Utility Commission of
        Oregon and the Washington Utilities and Transportation Commission
        relating to the issuance and sale of the Notes; and (i) the records of
        various corporate and other proceedings relating to the authorization,
        issuance and sale of the Notes.  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, and
        September 26, 1996 (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; provided, however,
        that further authorization must be obtained by the Company under the
        public utility laws of the States of Oregon and Washington prior to
        any sale of any Note by the Company to either of you, as principal.

                  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 Public Utility Commission of Oregon and the
        Washington Utilities and Transportation Commission 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 reference 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.

                  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 Deloitte & Touche LLP]


                  The letter of Deloitte & Touche LLP will state in effect
        that: 

                  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.
