                          NORTHWEST NATURAL GAS COMPANY

                                   Common Stock


                     Price to the Company:  $_____ per Share


                                                __________ __, 1994


   To the Underwriters named in Schedule I hereto

   Dear Sirs:

             Northwest Natural Gas Company, an Oregon corporation (the
   "Company"), proposes, subject to the terms and conditions stated herein, to
   issue and sell to you the aggregate number of shares of its Common Stock
   set forth opposite your respective names in Schedule I hereto, at the price
   to the Company set forth above.  In addition, for the sole purpose of
   covering over-allotments in connection with the sale of such securities,
   the Company proposes to grant to you an option (the "Option") to purchase
   from the Company, in the same proportions as set forth in Schedule I
   hereto, not more than an additional ________ shares of its Common Stock,
   exercisable within the period of 30 days from the date hereof, at the Price
   to the Company set forth above.  As used herein (except in Sections 2, 4
   and 6 hereof where it shall include only the aggregate amount of Common
   Stock set forth in Schedule I hereto), the term "Securities" shall be
   deemed to include both the aggregate amount of Common Stock set forth in
   Schedule I hereto and the aggregate amount of Common Stock to be purchased
   by you upon the exercise of the Option.

             1.  Representations and Warranties of the Company.  The Company
                 ---------------------------------------------
   represents and warrants to, and agrees with, each of you that:

             (a)  A registration statement with respect to the Securities has
   been prepared by the Company in conformity with the requirements of the
   Securities Act of 1933, as amended (the "Act"), and the rules and
   regulations (the "Rules and Regulations") of the Securities and Exchange
   Commission (the "Commission") under the Act, has been filed with the
   Commission and has become effective.  Copies of the registration statement,
   together with all amendments, if any, and of the prospectus contained
   therein, in the form in which it became effective, including the documents
   incorporated in such prospectus by reference, have heretofore been
   delivered to you.  The registration statement in the form in which it most
   recently became effective, including all exhibits thereto, is referred to
   hereinafter as the "Registration Statement".  The prospectus, including the
   documents incorporated therein by reference, contained in the Registration
   Statement is referred to hereinafter as the "Prospectus"; provided, that,
   when, on or after the date hereof, the Prospectus shall be supplemented
   with respect to the Securities (the "Prospectus Supplement") or shall be
   completed pursuant to Rule 430A (the "Completed Prospectus"), in a filing
   with the Commission pursuant to Rule 424(b) under the Act, "Prospectus",
   for all purposes of this Agreement, except this Section 1, shall mean the
   Prospectus as so supplemented or completed;

             (b)  No stop order with respect to the Registration Statement has
        been issued by the Commission under the Act and no proceeding therefor
        of which the Company has received notice has been instituted; the
        Registration Statement, at the time it became effective, conformed in
        all material respects to the requirements of the Act and the Rules and
        Regulations; on the date hereof, neither the Registration Statement
        nor the Prospectus contains an untrue statement of a material fact or
        omits to state a material fact required to be stated therein or
        necessary to make the statements therein, in the light of the circum-
        stances under which they were made, not misleading; and each document
        incorporated by reference in the Prospectus and filed pursuant to the
        Securities Exchange Act of 1934 (the "Exchange Act") conformed when so
        filed in all material respects to the requirements of the Exchange Act
        and the applicable rules and regulations thereunder;

             (c)  Since the respective dates as of which information is given
        in the Prospectus, there has not been any material adverse change in
        the business, property or financial condition of the Company, and
        there has not been any material transaction entered into by the
        Company other than transactions in the ordinary course of business and
        transactions referred to in, or contemplated by, the Prospectus; and
        the Company does not have any material contingent obligation which is
        not disclosed in the Prospectus;

             (d)  The consummation by the Company of the transactions herein
        contemplated and the fulfillment of the terms hereof will not result
        in a breach of any of the terms or provisions of, or constitute a
        default under, any statute, indenture, mortgage, deed of trust or
        other agreement or instrument 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, or any order, rule or regulation applicable to the Company of
        any court or governmental agency or body having jurisdiction over the
        Company or any of its properties; no approval, authorization, consent
        or order of any public board or body is legally required for the
        issuance and sale of the Securities by the Company hereunder, except
        such as may be issued by the Public Utility Commission of Oregon and
        the Washington Utilities and Transportation Commission or be required
        under the Act or state securities laws;

             (e)  The financial statements, together with related notes,
        incorporated by reference in the Prospectus present fairly the
        financial position and the results of operations of the Company on the
        bases set forth in such statements and related notes at the dates or
        for the periods to which they apply; and such statements and related
        notes have been prepared in accordance with generally accepted
        principles of accounting, consistently applied throughout the periods
        involved, except as otherwise stated therein;

             (f)  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 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 and each of the Company's subsidiaries has been duly
        incorporated and is validly existing as a corporation in good standing
        under the laws of the jurisdiction of its incorporation, with full
        power and authority to own or lease its properties and conduct its
        business, and is duly qualified to do business and is in good standing
        in each jurisdiction in which the character of the business conducted
        by it or the location of the properties owned or leased by it makes
        such qualification necessary;

             (g)  All of the outstanding shares of the capital stock of the
        Company have been duly and validly authorized and issued and are fully
        paid and non-assessable; when the Securities shall have been delivered
        against payment therefor as provided herein, they will have been duly
        and validly authorized and issued and fully paid and non-assessable;
        and the Securities conform to the description thereof contained in the
        Prospectus; and

             (h)  Other than as set forth in the Prospectus, there are no
        legal, governmental or administrative proceedings pending to which the
        Company is a party or of which any property of the Company is the
        subject, the outcome of which, in the opinion of the Company, would
        singly or in the aggregate have a material adverse effect on the
        business, property or financial position of the Company; and, to the
        best of the Company's knowledge, no such proceedings are threatened or
        contemplated by governmental authorities or threatened by others.

             2.  Purchase and Sale.  Subject to the terms and conditions
                 -----------------
   herein set forth, the Company agrees to sell to each of you, and each of
   you agrees, severally and not jointly, to purchase from the Company, at the
   Price to the Company set forth in Schedule I hereto, the Securities in the

             In addition, the Company hereby grants to you the Option.  The
   Option may be exercised, in whole or in part, on one occasion during the
   term thereof by written notice from you to the Company.  Such notice shall
   set forth the number of shares of Common Stock (the "Option Shares") as to
   which the Option is being exercised and specify the date of delivery of,
   and payment for, such shares, which date shall be neither earlier than the
   latter of the Time of Delivery or the second business day after the date of
   exercise nor later than the seventh business day after the date of
   exercise.

             3.  Offering.  Subject to the terms and conditions herein set
                 --------

   therefor, in Federal or other immediately available funds [New York
   Clearing House funds] payable to the order of the Company, shall be made at
   the office of Reid & Priest, 40 West 57th Street, New York, New York, at
   10:00 A.M., New York City time, on the fifth business day after the date
   hereof, or at such other place, time and date as shall be agreed upon in
   writing by the Company and you.  The hour and date of such delivery and
   payment are herein called the "Time of Delivery".

             The Securities shall be delivered to you for your respective
   accounts in fully registered form and in such authorized denominations and
   registered in such names as you may reasonably request in writing not later
   than 2:00 P.M., New York City time, on the second business day after the
   date hereof, or to the extent not so requested, registered in your
   respective names in such authorized denominations as the Company shall
   determine.  The Company agrees to make the Securities available to you for
   checking purposes not later than 2:00 P.M., New York City time, on the last
   full business day preceding the Time of Delivery, at the office of Bankers
   Trust Company, or at such other place, time or date as may be agreed upon
   between the Company and you.

             Delivery of the Option Shares and payment therefor, in New York
   Clearing House funds payable to the order of the Company, shall be made at
   the office of Reid & Priest, 40 West 57th Street, New York, New York, at
   10:00 A.M., New York City time, on the date specified by you in accordance
   with Section 2 hereof, or at such other place, time and date as shall be
   agreed upon in writing by the Company and you.  The hour and date of such
   delivery and payment are herein called the "Option Shares Time of
   Delivery".

             The Option Shares shall be delivered to you for your respective
   accounts in fully registered form and in such authorized denominations and
   registered in such names as you may reasonably request in writing not later
   than 2:00 P.M., New York City time, on the second business day preceding
   the Option Shares Time of Delivery, or to the extent not so requested,

   City time, on the last full business day preceding the Option Shares Time
   of Delivery, at the office of Bankers Trust Company, or at such other

             If any one or more of you shall default on your obligation or
   obligations to purchase and pay for the Securities which you have agreed
   herein to purchase and pay for (such of you which shall have so defaulted
   being referred to herein as the "Defaulting Underwriter"), the Company
   shall immediately give written notice thereof to each of you which shall
   not have so defaulted (the "Non-defaulting Underwriters") or, if one or
   more of you shall have executed this Agreement as the representative or
   representatives of the Underwriters named in Schedule I hereto, to such
   representative or representatives, and the Non-defaulting Underwriters
   shall have the right, within 24 hours after the receipt of such notice by
   the Non-defaulting Underwriters or their representative or representatives,
   to determine to purchase or to procure one or more others, members of the
   National Association of Securities Dealers, Inc. ("NASD") and satisfactory
   to the Company, to purchase, upon the terms herein set forth, the amount of
   the Securities which the Defaulting Underwriter so agreed to purchase.  If
   the Non-defaulting Underwriters shall determine to exercise such right,
   they shall give notice to the Company of such determination within 24 hours
   after their receipt of notice from the Company of such default, and,
   thereupon, the Time of Delivery shall be postponed for such period, not
   exceeding three business days, as the Company shall determine, in order
   that the required changes in the Registration Statement, the Prospectus and
   any other documents or arrangements may be effected.  If, in the event of
   such a default, the Non-defaulting Underwriters shall fail to give such
   notice or, within such 24-hour period, shall give notice to the Company
   that the Non-defaulting Underwriters will not exercise such right, this
   Agreement may be terminated by the Company, upon notice given to the Non-
   defaulting Underwriters (or their representative or representatives),
   within a further period of 24 hours.  If the Company shall not elect to so
   terminate this Agreement, it shall have the right:

             (a)  to require the Non-defaulting Underwriters to purchase and
        pay for the respective amounts of the Securities which they have
        severally agreed to purchase hereunder and, in addition, to purchase
        and pay for (in proportion to their respective commitments hereunder
        except as may be otherwise determined by the Non-defaulting
        Underwriters) the amount of the Securities which the Defaulting
        Underwriter shall have failed to purchase up to 10% of the respective
        amounts of the Securities which the Non-defaulting Underwriters have
        otherwise agreed to purchase, and/or

             (b)  to procure one or more others, members of the NASD, to
        purchase, upon the terms herein set forth, the amount of the
        Securities which the Defaulting Underwriter agreed to purchase or that
        portion thereof which the Non-defaulting Underwriters shall not be
        obligated to purchase pursuant to the foregoing clause (a).

   In the event the Company shall exercise its rights under (a) and/or (b)
   above, the Company shall give notice thereof to the Non-defaulting
   Underwriters (or their representative or representatives) within such
   further period of 24 hours, and, thereupon, the Time of Delivery shall be
   postponed for such period, not exceeding three business days, as the
   Company shall determine, in order that the required changes in the
   Registration Statement, the Prospectus and any other documents or
   arrangements may be effected.

             Any action taken by the Company under this Section 4 shall not
   relieve any Defaulting Underwriter from liability in respect of its
   obligations under this Agreement.  Termination by the Company under this
   Section 4 shall be without liability on the part of the Company or any Non-
   defaulting Underwriter; provided, however, that such termination shall not
   affect the payment obligations set forth in Section 5 hereof.

             5.  Covenants of the Company.  The Company agrees with each of
                 ------------------------
   you that it will:

             (a)  Promptly deliver to you a copy of the Registration Statement
        and of all amendments thereto (in each case including copies of all
        documents (other than exhibits) incorporated therein by reference and
        all exhibits filed therewith), either signed or certified by an
        officer of the Company, and including a copy of each consent and
        opinion included therein or filed as an exhibit thereto, either signed
        or certified by an officer of the Company, and as many unsigned copies
        of the Registration Statement and such amendments, as you may
        reasonably request.  The Company also will deliver to you as soon as
        practicable after the date of this Agreement and thereafter from time
        to time, during such period of time as a prospectus relating to the
        Securities is required to be delivered under the Act, as many copies
        of the Prospectus, including any amendments or supplements thereto, as
        you may reasonably request for the purposes of the Act.

             (b)  Promptly advise you (i) when any amendment of the
        Registration Statement shall have become effective, (ii) of any
        request by the Commission for any amendment of the Registration
        Statement or the Prospectus, and (iii) of the issuance of any stop
        order under the Act with respect to the Registration Statement or the
        institution of any proceedings therefor of which the Company shall
        have received notice.  The Company will use its best efforts to
        prevent the issuance of any such stop order and to secure the prompt
        removal thereof, if issued.  The Company will not file any amendment
        to the Registration Statement or supplement to the Prospectus unless
        the Company has furnished to you a copy for your review prior to
        filing.

             (c)  Pay all expenses and taxes (excluding any transfer taxes) in
        connection with (i) the preparation and filing by it of the
        Registration Statement and the Prospectus, (ii) the preparation and
        delivery of this Agreement, (iii) all corporate and regulatory actions
        precedent to the issuance and delivery of the Securities, (iv) the
        issuance and delivery of the Securities, (v) except as provided in
        Section 5(d) hereof, the printing and delivery to you of reasonable
        quantities of the Registration Statement, the Prospectus and any
        amendment or supplement, (vi) the fees and expenses of any transfer
        agent and registrar, and (vii) the qualification of the Securities for
        offering and sale under state securities laws, including the fees, not
        to exceed $5,000, and disbursements of your counsel in connection with
        such qualification and in connection with blue sky surveys.

             (d)  During such period of time (not exceeding nine months) after
        the effective date of the Registration Statement as you may be
        required by law to deliver a prospectus, if either the Company shall
        become aware or you shall advise the Company in writing of the
        occurrence of any event which should be set forth in a supplement to
        or an amendment of the Prospectus in order to make the Prospectus not
        misleading in the light of then existing circumstances, the Company
        will forthwith, at its expense, prepare and furnish to you a
        reasonable number of copies of a supplement or an amendment to the
        Prospectus which will supplement or amend the Prospectus so that as so
        supplemented or amended it will not contain any untrue statement of a
        material fact or omit to state any material fact necessary in order to
        make the statements therein, in the light of then existing
        circumstances, not misleading.  In case any of you shall be required
        to deliver a prospectus after the expiration of nine months from the
        date of this Agreement, the Company, upon your request, will furnish
        to you, at your expense, a reasonable quantity of a supplemented or
        amended prospectus, or supplements or amendments to the Prospectus
        complying with Section 10(a) of the Act.

             (e)  Make generally available to its security holders, as soon as
        practicable, an earning statement (which need not be audited) covering
        a period of 12 months beginning on the first day of the Company's
        fiscal quarter next succeeding the effective date of the Registration
        Statement.

             (f)  Furnish such proper information as may be lawfully required
        and otherwise cooperate in qualifying the Securities for offer and
        sale under the securities or blue sky laws of such jurisdictions as
        you may designate, and file and make in each year such statements or
        reports as are or may be reasonably required by the laws of such
        jurisdictions; provided, however, that the Company shall not be
        required to qualify as a foreign corporation or dealer in securities,
        or to file any consents to service of process under the laws of any
        jurisdiction, or to meet other requirements deemed by the Company to
        be unduly burdensome.

             (g)  Except for sales of equity securities pursuant to
        shareholder and employee plans, during the period beginning on the
        date of this Agreement and continuing to and including the 45th day
        following the Time of Delivery, not to offer, sell, continue to sell
        or otherwise dispose of any other of its securities of the same class
        as the Securities without your prior consent.

             All fees and disbursements of your counsel (exclusive of fees and
   expenses of such counsel which are to be paid by the Company as set forth
   in subsection (vi) of Section 5(c) hereof) shall be paid by you; provided,
   however, that if this Agreement shall be terminated in accordance with the
   provisions of Section 6, 7 or 9 hereof, the Company shall reimburse you for
   the amount of such fees and disbursements.  The Company shall not be
   required to pay any amount for any of your expenses except as provided in
   the preceding sentence.  The Company shall not in any event be liable to
   any of you for damages on account of the loss of anticipated profits.

             6.  Conditions of Your Obligations to Purchase the Securities. 
                 ---------------------------------------------------------
   Your several obligations to purchase and pay for the Securities shall be
   subject to the accuracy in all material respects of the representations and
   warranties of the Company set forth in Section 1 hereof as of the date
   hereof, to the accuracy of the statements of officers of the Company made
   in any certificate given pursuant to the provisions hereof, to the

        Registration Statement shall be in effect at the Time of Delivery; no

        date; and no proceedings for any such purpose shall be pending before,
        or threatened by, the Commission on such date, and you shall have
        received a certificate dated the Time of Delivery and signed by an
        executive officer of the Company to the effect that no such order is
        in effect and that no proceedings for any such purpose are pending
        before, or to the knowledge of the Company threatened by, the
        Commission; (ii) there shall not have been any change in the capital
        stock of the Company nor any material increase in the short-term or
        long-term debt of the Company (other than in the ordinary course of
        business) from that set forth or contemplated in the Registration
        Statement or the Prospectus (or any amendment or supplement thereto);
        (iii) there shall not have been, since the respective dates as of
        which information is given in the Registration Statement and the
        Prospectus (or any amendment or supplement thereto), except as may

        any amendment or supplement thereto), any material adverse change in
        the business, property, financial condition or results of operations
        of the Company and its subsidiaries taken as a whole; and (iv) the
        Company and its subsidiaries shall not have any liabilities or

        set forth, and containing no provision unacceptable to you by reason
        of the fact that it is materially adverse to the Company (it being

        such unacceptable provision).

             (c)  At the Time of Delivery, you shall have received from Bruce

             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, 1993,
             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) any material modifications should be made to the
                  unaudited condensed consolidated financial statements
                  incorporated by reference in the Registration Statement for
                  them to be in conformity with generally accepted accounting
                  principles, or (2) the unaudited condensed consolidated
                  financial statements incorporated by reference in the
                  Registration Statement do not comply with the applicable
                  accounting requirements of the Exchange Act as they apply to
                  Form 10-Q and the related published rules and regulations; 

                       (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 Preference Stock or Convertible Debentures, and

                  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

                  (iv)  They have performed certain other specified procedures
             with respect to certain amounts and percent-ages set forth in the

             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.

             (e)  At the Time of Delivery, you shall have received a

        post-effective amendment to the Registration Statement shall have been

        referred to in Section 1(b) hereof shall be deemed, for the purposes
        of such certificate, to include such amendment, (B) if the Prospectus
        Supplement or the Completed Prospectus shall have been filed pursuant
        to Rule 424 under the Act, the Prospectus referred to in Sections
        1(b), (c), (e), (f) and (g) hereof shall be deemed, for the purposes
        of such certificate, to be the Prospectus as so supplemented or
        completed, and (C) the Company's representations and warranties with
        respect to the accuracy and sufficiency of the Prospectus shall not
        apply to any statements or omissions in the Prospectus Supplement or
        the Completed Prospectus made in reliance upon and in conformity with
        the information furnished in writing to the Company, by or on behalf
        of you, specifically for use therein, (ii) the Company has performed
        all of its obligations hereunder to be performed at or prior to the
        Time of Delivery, (iii) if the Company shall have been required to
        file the Prospectus Supplement or the Completed Prospectus, as the
        case may be, with the Commission pursuant to Rule 424(b) under the
        Act, the Company has done so, and (iv) the orders described in Section
        6(b) hereof are in full force and effect.

             (f)  All legal proceedings to be taken in connection with the

        its rating assigned to any debt securities or preferred or preference
        stock of the Company, or (ii) it is reviewing its rating assigned to,
        or placing on credit watch, any debt securities or preferred or
        preference stock of the Company with a view to downgrading, or with
        negative implications, or direction not determined.  

             (h)  Subsequent to the date of this Agreement, there shall not
        have occurred (i) any material change in or affecting the business,
        properties, financial condition or results of operations of the
        Company and its subsidiaries taken as a whole not contemplated by the
        Prospectus or any amendment or supplement thereto (including the
        documents incorporated by reference therein at the date thereof),
        which in your opinion, would materially and adversely affect the
        market for the Securities, or (ii) any event or development relating
        to or involving the Company or any officer or director of the Company
        which makes any statement made in the Prospectus (including the
        documents incorporated therein by reference at the date thereof)
        untrue or which, in the opinion of the Company and its counsel or you
        and your counsel, requires the making of any addition to or change in
        the Prospectus or any amendment or supplement thereto in order to
        state a material fact required by the Act to be stated therein or
        necessary in order to make the statements therein not misleading, if
        amending or supplementing the Prospectus to reflect such event or

        the Securities.

             (i)  The Securities shall be approved for trading, or shall be
        capable of being traded, in the over-the-counter market.

        you and each person who controls any of you within the meaning of
        Section 15 of the Act against any and all losses, claims, damages or
        liabilities, joint or several, to which you and they or any of you or
        them may become subject under the Act, the Exchange Act or any other
        statute or common law, and to reimburse each of you and each such
        controlling person for any legal or other expenses (including, to the
        extent hereinafter provided, reasonable counsel fees) incurred by you
        or them in connection with investigating any such losses, claims,
        damages or liabilities or in connection with defending any actions,
        insofar as such losses, claims, damages, liabilities, expenses or
        actions arise out of or are based upon any untrue statement or alleged
        untrue statement of a material fact contained in the Registration
        Statement or Prospectus as amended or supplemented (if any amendments
        or supplements thereto shall have been furnished) or 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; provided, however, that the indemnity agreement contained
        in this subsection (a) shall not apply to any such losses, claims,
        damages, liabilities, expenses or actions arising out of, or based
        upon, any such untrue statement or alleged untrue statement, or any
        such omission or alleged omission, if such statement or omission was
        made in reliance upon written information furnished to the Company by
        or on behalf of any of you specifically for use in connection with the
        preparation of the Registration Statement, the Prospectus  or any
        amendment or supplement to either thereof; and provided, further, that
        the indemnity agreement contained in this paragraph shall not inure to
        the benefit of any of you (or of any of your controlling persons) on
        account of any losses, claims, damages, liabilities, expenses or
        actions arising from the sale of any of the Securities to any person
        if a copy of the Prospectus, as amended or supplemented (if any
        amendments or supplements thereto shall have been furnished),
        excluding any document incorporated by reference therein, shall not
        have been sent or given to such person with or prior to the written
        confirmation of the sale involved, unless such failure is the result
        of non-compliance by the Company with Section 5(a) hereof.  The
        indemnity agreement of the Company contained in this Section 8(a) and
        the representations and warranties of the Company contained in Section
        1 hereof shall remain operative and in full force and effect,
        regardless of any investigation made by or on behalf of any of you or
        any such controlling person, and shall survive the delivery of the
        Securities.  The indemnity agreement of the Company contained in this
        Section 8(a) shall be in addition to any liability which the Company
        may otherwise have to an indemnified party hereunder.

             (b)  Each of you, severally, agrees to indemnify and hold
        harmless the Company, its directors, each of its officers who shall
        have signed the Registration Statement and each person who controls
        the Company within the meaning of Section 15 of the Act against any
        and all losses, claims, damages or liabilities, joint or several, to
        which they or any of them may become subject under the Act, the
        Exchange Act or any other statute or common law, and to reimburse each
        of them for any legal or other expenses (including, to the extent
        hereinafter provided, reasonable counsel fees) incurred by them in
        connection with investigating any such losses, claims, damages or
        liabilities or in connection with defending any action, insofar as
        such losses, claims, damages, liabilities, expenses or actions arise
        out of or are based upon any untrue statement or alleged untrue
        statement of a material fact contained in the Registration Statement
        or Prospectus as amended or supplemented (if any amendments or sup-
        plements thereto shall have been furnished) or 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, if
        such statement or omission was made in reliance upon written
        information furnished to the Company by or on behalf of any of you
        specifically for use in connection with the preparation of the
        Registration Statement, the Prospectus or any amendment or supplement
        to either thereof.  Your respective indemnity agreements contained in
        this Section 8(b) and the representations and warranties of each of
        you which shall have signed this Agreement contained in Section 12
        hereof shall remain operative and in full force and effect, regardless
        of any investigation made by or on behalf of the Company or any such
        director, officer or controlling person, and shall survive the
        delivery of the Securities.  The indemnity agreement of each of you
        contained in this Section 8(b) shall be in addition to any liability
        which you may otherwise have to an indemnified party hereunder.

             (c)  Each of the Company and you, severally, agrees that, upon
        the receipt of notice of the commencement of any action against it,
        any of its directors or officers, or any person controlling it as
        aforesaid, in respect of which indemnity may be sought on account of
        any indemnity agreement contained herein, it will promptly give a
        notice of the commencement thereof to the party or parties against
        whom indemnity shall be sought hereunder, but the omission so to
        notify such indemnifying party or parties  of any such action shall
        not relieve such indemnifying party or parties from any liability
        which it or they may have to the indemnified party otherwise than on
        account of such indemnity agreement.  In case such notice of any such
        action shall be so given, such indemnifying party shall be entitled to
        participate at its own expense in the defense or, if it so elects, to
        assume (in conjunction with any other indemnifying parties) the
        defense of such action, in which event such defense shall be conducted
        by counsel chosen by such indemnifying party or parties.  If the
        indemnifying party shall elect to assume the defense of such action,
        any indemnified party or parties who shall be defendant or defendants
        in such action shall have the right to employ separate counsel in any
        such action and participate in the defense thereof, but the fees and
        expenses of such counsel retained by it or them shall be at the
        expense of such indemnified party or parties unless (i) the employment
        of such counsel has been specifically authorized in writing by the
        indemnifying party or parties or (ii) counsel chosen by the
        indemnifying party or parties as aforesaid shall not be satisfactory
        to the indemnified party or parties or shall for any reason be unable
        to act for or continue to act for such indemnified party or parties;
        provided, however, that in any case or cases to which the foregoing
        clause (ii) shall apply, the indemnifying party or parties shall not,
        in connection with any one such action or separate but substantially
        similar or related actions in the same jurisdiction arising out of the
        same general allegations or circumstances, be liable for the
        reasonable fees and expenses of more than one separate firm of
        attorneys for all such indemnified parties, which firm shall be chosen
        by the indemnified party or parties and satisfactory to the
        indemnifying party or parties.  If the indemnifying party shall elect
        not to assume the defense of such action, such indemnifying party will
        reimburse such indemnified party or parties for the reasonable fees
        and expenses of any counsel retained by them.

             (d)  In order to provide for just and equitable contribution in
        circumstances in which the indemnification provided for in Sections
        8(a) or (b) hereof shall be due in accordance with its terms but for
        any reason shall be unavailable or insufficient to hold any
        indemnified party thereunder harmless in respect of any losses,
        claims, damages or liabilities referred to therein, the Company and
        each of you severally shall contribute to the aggregate losses,
        claims, damages and liabilities to which the Company and one or more
        of you may be subject, as a result of such losses, claims, damages or
        liabilities, in such proportion as is appropriate to reflect the
        relative fault of the Company on the one hand and each of you on the
        other in connection with the statements or omissions which resulted in
        such losses, claims, damages or liabilities as well as any other
        equitable considerations, including, with respect only to any losses,
        claims, damages or liabilities referred to in Section 8(a) hereof,
        relative benefit.  Relative fault shall be determined by reference to,
        among other things, whether the untrue or alleged untrue statement of
        a material fact or the omission or alleged omission to state a
        material fact relates to information supplied by the Company, on the
        one hand, or you, on the other, and the parties' relative intent,
        knowledge and 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 you on the other shall be deemed to be
        in the same proportion as the total net proceeds from the offering of
        the Securities (before deducting expenses) received by the Company
        bear to the total underwriting discounts and commissions received by
        you with respect to the offering of the Securities.  Notwithstanding
        the foregoing, 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 Company and you agree that it would not be
        just and equitable if contribution pursuant to this Section 8(d) were
        determined (i) by any method of allocation which does not take account
        of the equitable considerations referred to above in this Section
        8(d), or (ii) with respect only to any losses, claims, damages or
        liabilities referred to in Section 8(a) hereof, by pro rata allocation
        (even if you were treated as one entity for such purpose).  The amount
        paid or payable by a party entitled to contribution as a result of the
        losses, claims, damages or liabilities referred to above in this
        Section 8(d) shall be deemed to include any legal or other expenses
        reasonably incurred by such party in connection with investigating or
        defending any such action or claim.  For purposes of this Section
        8(d), each person, if any, who controls any of you within the meaning
        of Section 15 of the Act shall have the same rights to contribution as
        you, and each director and officer of the Company who shall have
        signed the Registration Statement and each person, if any, who
        controls the Company within the meaning of Section 15 of the Act shall
        have the same rights to contribution as the Company, subject, in each
        case, to the fourth sentence of this Section 8(d).

             9.  Termination.
                 -----------

             (a)  This Agreement shall be subject to termination at any time
        prior to the Time of Delivery, or your exercise of the Option may be
        rescinded at any time prior to the Option Shares Time of Delivery, in
        your absolute discretion, upon  notice thereof to the Company, if
        prior to the Time of Delivery or the Option Shares Time of Delivery,
        as the case may be, (i) trading in securities generally on the New
        York Stock Exchange, American Stock Exchange or National Association
        of Securities Dealers Automated Quotations System shall have been
        suspended or materially limited, (ii) a general moratorium on
        commercial banking activities in New York or Oregon shall have been
        declared by either Federal or state authorities, or (iii) there shall
        have occurred any outbreak or escalation of hostilities or other
        international or domestic calamity, crisis or change in political,
        financial or economic conditions, the effect of which on the financial
        markets of the United States is such as to make it, in your judgment,
        impracticable or inadvisable to commence or continue the offering of
        the Securities at the offering price to the public set forth on the
        cover page of the Prospectus (or any amendment or supplement thereto)
        or to enforce contracts for the resale of the Securities by you.  This
        Agreement may also be terminated at any time prior to the Time of
        Delivery, or your exercise of the Option may be rescinded at any time
        prior to the Option Shares Time of Delivery, upon notice thereof to
        the Company if, in the judgment of one or more of you which have
        agreed to purchase 50% or more of the Securities, the subject matter
        of any amendment or supplement to the Registration Statement or the
        Prospectus renders it either inadvisable to proceed with the public
        offering of the Securities or inadvisable to proceed with the delivery
        of the Securities to be purchased hereunder.  Any termination of this
        Agreement pursuant to this Section 9 shall be without liability of any
        party to any other party, except as otherwise provided in Section 5
        hereof.

             (b)  Notwithstanding any termination of this Agreement pursuant
        to this Section 9, the provisions of Section 8 hereof shall remain in
        effect.

             10.  Notices.  All statements, requests, notices and agreements
                  -------
   hereunder shall be in writing or by telephone if confirmed in writing
   within 24 hours, and if to you, shall be sufficient in all respects if
   delivered or sent by registered mail either to you at your address given on
   the last page hereof or, if this Agreement shall have been executed on your
   behalf by a representative as provided in Section 13 hereof, to your
   representative at its address given on the last page hereof; and if to the
   Company shall be sufficient in all respects if delivered or sent by
   registered mail to Northwest Natural Gas Company, One Pacific Square, 220
   N.W. Second Avenue, Portland, Oregon 97209, Attention:  Treasurer and
   Controller; provided, however, that any notice to any of you pursuant to
   Section 8(c) hereof shall be delivered or sent by registered mail to such
   party at its principal executive offices.

             11.  Information for Use in Prospectuses.  The information
                  -----------------------------------
   specified in Schedule I hereto shall be deemed to have been furnished in
   writing to the Company by you specifically for use therein.

   agreement on behalf of all of you made or given either by all of such
   undersigned representatives jointly or by any of such undersigned
   representatives individually.

             13.  Miscellaneous.

        benefit of, you, the Company and, to the extent provided in Section 8
        hereof, the directors and officers of the Company and each person who
        controls the Company or any of you, and their respective heirs,
        executors, administrators, successors and assigns, and no other person
        shall acquire or have any right under or by virtue of this Agreement. 
        No purchaser of any of the Securities from any of you shall be deemed
        a successor or assign by reason merely of such purchase.

             (b)  This Agreement shall be construed in accordance with the
        laws of the State of New York.

             (d)  This Agreement has been prepared upon the assumption that
        there will be more than one Underwriter purchasing the Securities. 
        Consequently, if there should be only one Underwriter named in

                                           _____________ __, 1994




   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the  Underwriting  Agreement, dated
   ____________ __, 1994 (the "Agreement"), between the Company and you of
   __________ shares of the Company's Common Stock (the "Securities"), please
   be advised that, as General Counsel of the Company, I have participated in
   the preparation of or reviewed (a) the registration statement relating to
   the Securities filed by the Company with the Securities and Exchange
   Commission (the "Commission") under the Securities Act of 1933 (the
   "Securities Act") (such registration statement, as it became effective,
   being hereinafter called the "Registration Statement" and the prospectus
   constituting a part of the Registration Statement, in the form (i)
   completed or supplemented, (ii) dated ___________ __, 1994, and (iii) filed
   with the Commission pursuant to Rule 424(b) under the Securities Act,
   including the documents incorporated therein by reference pursuant to Item
   12 of Form S-3 on the date hereof, being hereinafter called the "Pro-
   spectus"); (b) the proceedings before the Public Utility Commission of
   Oregon and the Washington Utilities and Transportation Commission for
   authority to issue and sell the Securities and the order or orders entered
   by the Commissions in respect thereto; (c) the Restated Articles of Incor-
   poration of the Company, its Bylaws and the actions taken by its Board of
   Directors and the Executive Committee thereof authorizing the issuance and
   sale of the Securities; and (d) such other matters as I have deemed to be
   necessary to enable me to render the opinions herein expressed.  I have not
   examined the Securities, except a specimen thereof, and have relied upon a
   certificate of the transfer agent and the registrar for the Securities as
   to the issuance, registration and countersignature thereof.

             In my examination of the documents referred to above, I have
   assumed the authenticity of all such documents submitted to me as
   originals, the genuineness of all signatures, the due authority of the
   persons executing such documents and the conformity to the originals of all
   documents submitted to me as copies.  

             Based upon the foregoing, 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
        Registration Statement.

             3.  All of the outstanding shares of capital stock of the
        Company have been duly and validly authorized and issued and are fully
        paid and non-assessable.

             4.  The Securities have been duly and validly authorized and,
        when the Securities shall have been delivered against payment therefor
        as provided in the Agreement, they will have been duly and validly
        issued and will be fully paid and non-assessable.

             5.  The Securities conform as to legal matters with the
        description thereof contained in the Prospectus.

             6.  The Registration Statement has become, and on the date
        hereof is, effective under the Securities Act, and, to the best of my
        knowledge, no proceedings for a stop order with respect thereto are
        pending under Section 8 of the Securities Act, and no order directed
        to the adequacy or accuracy of any document incorporated by reference
        in the Registration Statement or Prospectus has been issued by the
        Commission.

             7.  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 Securities; the issuance
        and sale of the Securities in accordance with the Agreement are in
        conformity with the terms of such orders; 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 Securities on the terms and
        conditions set forth in the Agreement.

             8.  The Agreement has been duly and validly authorized, executed
        and delivered by or on behalf of the Company.

             9.  There are no legal, governmental or administrative
        proceedings pending to which the Company is a party or of which any
        property of the Company is the subject, other than as set forth in the
        Prospectus and other than proceedings incident to the kind of business
        conducted by the Company, the outcome of which would not singly or in
        the aggregate have a materially adverse effect on the financial
        position, stockholders' equity or results of operations of the
        Company; and, to the best of my knowledge, no such proceedings are
        threatened or contemplated by governmental authorities or threatened
        by others.

             10.  The statements made in the Prospectus as to matters of law
        and legal conclusions which, as stated therein, have been set forth
        therein on my authority as an expert have been reviewed by me and are
        correct; and the descriptions of legal and governmental proceedings
        contained in the Prospectus are, to the best of my knowledge, accurate
        and fairly present the information required to be shown therein.

             11.  The consummation of the transactions contemplated in the
        Agreement and the fulfillment of the terms thereof will not result in
        a breach of any of the terms or provisions of, or constitute a default
        under, any statute, 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, or the Restated Articles of Incorporation or Bylaws of the
        Company or any order, rule or regulation of any court or other
        governmental body having jurisdiction over the Company or any of its
        property.

             Based upon my examination of the Registration Statement and the
   Prospectus and my familiarity, as General Counsel of the Company, with its
   business and affairs, I have no reason to believe either that the
   Registration Statement, as of the date that it became effective, contained
   any untrue statement of a material fact or omitted to state a material fact
   required to be stated therein or necessary to make the statements therein
   not misleading or that the Prospectus contains any 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, except that, in each case, no opinion or belief
   is expressed herein with respect to the financial statements or other
   financial data of the Company contained in the Registration Statement or
   the Prospectus.

             I am a member of the bars of the States of Oregon and Washington
   and do not hold myself out as an expert on the laws of any other state.  

             I have read the opinions of even date herewith rendered to you by
   Reid & Priest and Simpson Thacher & Bartlett, and I concur in the
   conclusions therein expressed, insofar as such conclusions involve
   questions of Oregon and Washington law.

             Reid & Priest and Simpson Thacher & Bartlett, as to matters
   governed by the laws of the State of Oregon or the State of Washington, may
   rely upon this opinion as if it were addressed directly to each of them; it
   being understood, however, that this opinion may be relied upon by you and
   by them only in connection with the issuance and sale of the Securities. 
   This opinion may not be relied upon by you or by them for any other
   purpose, or relied upon by any other person without, in each instance, my
   prior written consent.

                                                                             
                                             
   
                                           Very truly yours,


                                           BRUCE B. SAMSON

   
   
   


                                                                    EXHIBIT B



                                 [Reid & Priest]



                                           ___________ __, 1994

   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the  Underwriting  Agreement, dated
   _________ __, 1994 (the "Agreement"), between the Company and you of
   ___________ shares of the Company's Common Stock (the "Securities"), please
   be advised that, as counsel to the Company, we have participated in the
   preparation of or reviewed (a) the registration statement relating to the
   Securities filed by the Company with the Securities and Exchange Commission
   (the "Commission") under the Securities Act of 1933 (the "Securities Act")

   of the Registration Statement, in the form (i) completed or supplemented,
   (ii) dated _____________ __, 1994 and (iii) filed with the Commission
   pursuant to Rule 424(b) under the Securities Act, including the documents

   Securities; (d) and such other matters as we have deemed to be necessary to
   enable us to render the opinions herein expressed.  We have not examined
   the Securities, except a specimen thereof, and have relied upon a certifi-
   cate of the transfer agent and the registrar for the Securities as to the
   issuance, registration and countersignature thereof.
   
             In our examination of the documents referred to above, we have
   assumed the authenticity of all such documents submitted to us as
   originals, the genuineness of all signatures, the due authority of the
   persons executing such documents and the conformity to the originals of all
   documents submitted to us as copies.  

             Based upon the foregoing, 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.   All of the outstanding shares of capital stock of the
        Company have been duly and validly authorized and issued and are fully
        paid and nonassessable.

             3.   The Securities have been duly and validly authorized and,
        when the Securities shall have been delivered against payment therefor
        as provided in the Agreement, they will have been duly and validly
        issued and will be fully paid and non-assessable.

             4.   The Securities conform as to legal matters with the
        description thereof contained in the Prospectus.

             5.   The Registration Statement has become, and on the date
        hereof is, effective under the Securities Act, and, to the best of our
        knowledge, no proceedings for a stop order with respect thereto are
        pending under Section 8 of the Securities Act, and no order directed
        to the adequacy or accuracy of any document incorporated by reference
        in the Registration Statement or Prospectus has been issued by the
        Commission.

             6.   The Registration Statement, as of its effective date, and
        the Prospectus, as of the time it was filed with the Commission
        pursuant to Rule 424(b), complied as to form in all material respects
        with the requirements of the Securities Act, and the rules and
        regulations thereunder, and the documents incorporated by reference in
        the Prospectus on the date hereof complied as to form in all material
        respects with the requirements of the Securities Exchange Act of 1934
        and the rules and regulations thereunder at the respective times at
        which such documents were filed with the Commission, except that, in
        each case, we express no opinion with respect to the financial
        statements and other financial data contained in the Registration
        Statement or the Prospectus.
    
             7.   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 Securities; the issuance
        and sale of the Securities in accordance with the Agreement are in
        conformity with the terms of such orders; 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 Securities on the terms and
        conditions set forth in the Agreement.

              8.  The Agreement has been duly and validly authorized, executed
        and delivered by or on behalf of the Company.

             In passing upon the form of the Registration Statement and the
   Prospectus, we necessarily assume the correctness and completeness of the
   statements made therein by the Company and take no responsibility therefor,
   except as set forth in paragraph 4 above.  In the course of the preparation
   by the Company of the Registration Statement, we had conferences with
   certain of its officers and employees and with the General Counsel of the
   Company.  Our examination of the Registration Statement and the Prospectus
   and our discussions in the above-mentioned conferences did not disclose to
   us any information which gives us reason to believe either that the Reg-
   istration Statement, as of the date that it became effective, contained any
   untrue statement of a material fact or omitted to state a material fact re-
   quired to be stated therein or necessary to make the statements therein not
   misleading or that the Prospectus contains any 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, except that, in each case, no opinion or belief
   is expressed herein with respect to the financial statements or other fi-
   nancial data contained in the Registration Statement or the Prospectus.

             We are members of the New York Bar and do not hold ourselves out
   as experts on the laws of the States of Oregon and Washington.  As to all
   matters of Oregon and Washington law, we have relied, with your consent,
   upon an opinion addressed to you of even date herewith of Bruce B. Samson,
   Esq., General Counsel of the Company, whom we believe to be qualified to
   pass upon such matters.

             This opinion may be relied upon by you only in connection with
   the issuance and sale of the Securities.  This opinion may not be relied
   upon by you for any other purpose, or relied upon by any other person,
   without, in each instance, our prior written consent.

                                           Very truly yours,


                                           REID & PRIEST


   

                                                               EXHIBIT C

   [Representatives]

     and the other several 
     Underwriters named in Schedule I 
     to the Underwriting Agreement 
     dated ______, 199_ with 
     Northwest Natural Gas Company

   [Address]


   Dear Sirs:

             We have acted as your counsel in connection with the purchase by
   
   you of _______ shares of Common Stock, par value $3-1/6 per share (the
   
   "Shares"), of Northwest Natural Gas Company, an Oregon corporation (the
   
   "Company"), pursuant to the underwriting agreement referred to above (the
   
   "Underwriting Agreement"). 
   
             We have examined the Registration Statement on Form S-3 (File No.

   33-______) filed by the Company under the Securities Act of 1933, as

   amended (the "Act"), as it became effective under the Act (the

   "Registration Statement"); and the Company's prospectus dated ______, 199_, 
   
   as supplemented by the prospectus supplement dated _____, 199_  (the

   "Prospectus"), filed by the Company pursuant to Rule 424(b) of the rules
   
   and regulations of the Securities and Exchange Commission (the

   "Commission") under the Act, which pursuant to Form S-3 incorporates by

   reference or is deemed to incorporate by reference the Annual Report on

   Form 10-K of the Company for the fiscal year ended December 31, 199_, and

   ____________ (the "Exchange Act Documents"), each as filed under the

   Securities Exchange Act of 1934, as amended (the "Exchange Act").

   In addition, we have examined, and have relied as to matters of

   fact upon, the documents delivered to you at the closing (except the

   certificates representing the Shares, of which we have examined a 
   
   specimen), and upon originals or copies, certified or otherwise identified 
   
   to our satisfaction, of such corporate records, agreements, documents and 
   
   other instruments and such certificates or comparable documents or oral 
   
   statements of public officials and of officers and representatives of the 
   
   Company, and have made such other and further investigations, as we have 
   
   deemed relevant and necessary as a basis for the opinions hereinafter set 
   
   forth.

             In such examination, we have assumed the genuineness of all

   signatures, the legal capacity of natural persons, 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.

             Based upon the foregoing, and subject to the qualifications and

   limitations stated herein, we hereby advise you that in our opinion:  

             1.  The Company has been duly incorporated and is validly
        existing and in good standing as a corporation under the laws of the
        State of Oregon. 

             2.  The Shares have been duly authorized by the Company and, 
        upon payment and delivery in accordance with the Underwriting
        Agreement, will be validly issued, fully paid and non-
        assessable.
        
             3.  The statements made in the Prospectus under the captions
        "Description of Common Stock" and ________, insofar as they purport
        to constitute summaries of the terms of the Company's Restated 
        Articles of Incorporation, as amended, constitute accurate summaries 
        of the terms of such document in all material respects.

             4.  The Underwriting Agreement has been duly authorized, executed
        and delivered by the Company. 

             5.  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 Shares; the issuance
        and sale of the Shares in accordance with the Underwriting
        Agreement are in conformity with the terms of such orders; and no
        other approval or consent of any Federal, Oregon or Washington
        governmental body (except for any approval or consent under state
        "blue sky" or securities laws, as to which we express no opinion) is
        required for the issuance and sale of the Shares to you on the
        terms and conditions set forth in the Underwriting Agreement. 

             All legal proceedings taken by the Company in connection with the
             
   authorization and delivery of the Shares, and the legal opinions, dated

   the date hereof, rendered to you by Bruce B. Samson, Esq., General Counsel

   of the Company, and Reid & Priest, counsel for the Company, are in form

   satisfactory to us.  Insofar as the opinions expressed herein relate to or
   
   are dependent upon matters governed by the laws of the States of Oregon

   and/or Washington, we have relied upon the aforesaid opinion of Bruce B.

   Samson, Esq.  We express no opinion on matters relating to titles to

   property, franchises or the lien of the Company's Mortgage and Deed of

   Trust, dated as of July 1, 1946, as supplemented, to Bankers Trust

   Company and Stanley Burg (successor Individual Trustee), as Trustees.

   
             We have not independently verified the accuracy, completeness or

   fairness of the statements made or included in the Registration Statement,

   the Prospectus or the Exchange Act Documents and take no responsibility

   therefor, except as and to the extent set forth in paragraph 3 above.  In

   the course of the preparation by the Company of the Registration Statement

   and the Prospectus (excluding the Exchange Act Documents), we participated

   in conferences with certain officers and employees of the Company, with

   representatives of Deloitte & Touche and with counsel to the Company.  We

   did not prepare the Exchange Act Documents or review the Exchange Act

   Documents prior to their filing with the Commission.  Based upon our

   examination of the Registration Statement, the Prospectus and the Exchange

   Act Documents, our investigations made in connection with the preparation

   of the Registration Statement and the Prospectus (excluding the Exchange

   Act Documents) and our participation in the conferences referred to above,

   (i) we are of the opinion that the Registration Statement, as of its

   effective date, and the Prospectus, as of ____________, 199__, complied as

   to form in all material respects with the requirements of the Act and

   the applicable rules and regulations of the Commission thereunder and 
   
   that the Exchange Act Documents complied as to form when filed in 
   
   all material respects with the requirements of the Exchange Act and 
   
   the applicable rules and regulations of the Commission thereunder, 
   
   except that in each case we express no opinion with respect to
   
   the financial statements or other financial or statistical data contained

   or incorporated by reference in the Registration Statement, the Prospectus

   or the Exchange Act Documents, and (ii) we have no reason to believe that

   the Registration Statement [, as of its effective date (including the

   Exchange Act Documents on file with the Commission on such effective date),]

   [, as of the date of filing of the Annual Report on Form 10-K of the

   Company for the fiscal year ended December 31, 199_ (including such Annual

   Report for the fiscal year ended December 31, 199_),] contained any untrue

   statement of a material fact or omitted to state any material fact required

   to be stated therein or necessary in order to make the statements therein

   not misleading or that the Prospectus (including the Exchange Act

   Documents) contains any untrue statement of a material fact or omits 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, except that in each case we express no belief with respect to

   the financial statements or other financial or statistical data contained

   or incorporated by reference in the Registration Statement, the Prospectus

   or the Exchange Act Documents.

             We are members of the Bar of the State of New York and we do not

   express any opinion herein concerning any law other than the law of the

   State of New York and the federal law of the United States and, to the

   extent set forth herein and in reliance solely upon the aforesaid opinion

   of Bruce B. Samson, Esq., the laws of the States of Oregon and Washington.

             This opinion is rendered to you in connection with the above

   described transactions.  This opinion may not be relied upon by you for any
   
   other purpose, or relied upon by, or furnished to, any other person, firm

   or corporation without our prior written consent.

                                 Very truly yours,
