             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  Trust Indenture  Act of  1939, as  amended (the
        "Trust Indenture 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 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, the  Trust Indenture Act  and the Rules
        and  Regulations; on  the date  hereof, neither  the Registration
        Statement  (excluding  the  Statements   of  Eligibility  of  the
        Trustee(s) under  the Indenture)  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 circumstances 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)  The  Indenture and  the Securities have  been duly  and
        validly  authorized; and,  when  the Securities  shall have  been
        delivered  against  payment  therefor  as  provided  herein,  the
        Indenture and  the Securities  will be  legal, valid  and binding
        obligations of the Company,  enforceable in accordance with their
        terms, except as limited by bankruptcy, insolvency and other laws
        affecting  the enforcement  of mortgagees'  and other  creditors'
        rights, the Indenture will be qualified under the Trust Indenture
        Act, and the  Indenture and  the Securities will  conform to  the
        descriptions 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  on the  first  page hereof  plus accrued
   interest,  if any, thereon from the Interest Commencement Date set forth on
   the first page hereof to the Time of Delivery (as hereinafter defined), the
   Securities  in  the amounts  set forth  opposite  your respective  names in
   Schedule I hereto.

             3.   Offering.  Subject to the terms and conditions herein set
                  --------
   forth,  you will  make an  offering of  the Securities  upon the  terms and
   conditions set forth in the Prospectus.

             4.   Payment  and  Delivery.    Delivery of  the  Securities  and
   payment        ----------------------
   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  offices of Messrs. 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  the 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.

             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  and the Supplemental
        Indenture, (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  the
        Trustees  and 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  and  legal
        investment surveys.

             (d)   During such period of time (not exceeding nine months)
        after the effective date of this Agreement 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)    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

        on such date, and you shall have received a certificate dated the

        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  otherwise be stated in  the Registration
        Statement  and  Prospectus   (or  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  obligations,
        direct  or contingent (whether or  not in the  ordinary course of
        business), that  are material to the Company and its subsidiaries
        taken  as a whole, other than those reflected in the Registration
        Statement  or  the Prospectus  (or  any  amendment or  supplement
        thereto).

             (b)   At the Time of Delivery,  there shall be in full force
        and  effect orders of the Public Utility Commission of Oregon and
        the   Washington   Utilities   and    Transportation   Commission
        authorizing  the issuance and sale of the Securities on the terms
        and  conditions herein  set  forth, and  containing no  provision
        unacceptable to you  by reason of the fact that  it is materially
        adverse  to the  Company (it  being understood  that no  order in
        effect  on  the  date   hereof  contains  any  such  unacceptable
        provision).
        
             (c)  At  the Time of Delivery, you  shall have received from
        Bruce B. Samson,  Esq., General  Counsel of the  Company, Reid  &
        Priest, of counsel to the Company, and Simpson Thacher & Bartlett
        (a  partnership which  includes professional  corporations), your
        counsel, opinions,  dated the Time of  Delivery, in substantially
        the form and substance prescribed in Exhibits A, B, and C hereto.

             (d)  At the Time of  Delivery, Deloitte & Touche shall  have
        furnished to  you a letter,  dated the  Time of Delivery,  to the
        effect that:

                  (i)    They  are  independent public  accountants  with
             respect to the Company within the meaning of the Act and the
             applicable published Rules and Regulations;

                 (ii)    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;

                  (iii)    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, 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
             (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

                  (iv)   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.

             (e)   At the Time  of Delivery,  you shall  have received  a
        certificate,  dated  the  Time  of  Delivery  and  signed  by  an
        executive  officer of  the Company,  to the  effect that  (i) the
        Company's representations  and warranties set forth  in Section 1
        hereof are true  and correct at  and as of  the Time of  Delivery
        with  the same  effect  as if  made  at  and as  of  the Time  of
        Delivery; provided, that, (A)  if any post-effective amendment to
        the Registration  Statement shall  have been filed  subsequent to
        the  date  hereof,  the  Registration Statement  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 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,
        and  (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  issuance and sale of the Securities shall be satisfactory in
        form and substance to your counsel.

             (g)  There  shall   not  have   been  any  announcement   by  any
        "nationally  recognized statistical  rating organization",  as defined
        for purposes of Rule 436(g) under the Act, that (i)  it is downgrading
        its rating assigned  to the First  Mortgage Bonds or Preferred or 
        Preference Stock of the Company,  or (ii)  it is  reviewing its  
        rating assigned to,  or placing  on credit watch, the First Mortgage  
        Bonds or Preferred or Preference Stock with a view to  possible 
        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
        development would,  in your opinion,  adversely affect the  market for
        the Securities.

             In case any  of the conditions specified above in  this Section 6
   shall  not have been fulfilled at the  Time of Delivery, this Agreement may
   be terminated by one or more of  you which have agreed to purchase, in  the
   aggregate, 50%  or  more of  the  Securities, upon  notice  thereof to  the
   Company.   Any such termination shall be  without liability of any party to
   any other party, except as otherwise provided in Section 5 hereof.

             7.   Conditions of Company's Obligation.  The obligation of the
                  ----------------------------------
   Company to  deliver the Securities at the Time of Delivery shall be subject
   to the following conditions:
   
             (a)    No stop  order  suspending the  effectiveness  of the
        Registration  Statement  shall  be  in  effect  at  the  Time  of
        Delivery;  no order of the Commission directed to the adequacy or
        accuracy of any document  incorporated by reference therein shall
        be in  effect  at such  date;  and no  proceedings for  any  such
        purpose shall be pending before, or threatened by, the Commission
        on such date.

             (b)  At the Time  of Delivery, there shall be in  full force
        and  effect orders of the Public Utility Commission of Oregon and
        the   Washington   Utilities   and    Transportation   Commission
        authorizing  the issuance and sale of the Securities on the terms
        and  conditions herein  set forth,  and containing  no provisions
        unacceptable to  the Company  by reason  of the  fact that it  is
        materially  adverse to the  Company (it being  understood that no
        order in effect on the date hereof contains any such unacceptable
        provision).

             In case any of the conditions  specified above in this Section  7
   shall not have  been fulfilled at the Time of  Delivery, this Agreement may
   be terminated  by  the Company,  upon  notice thereof  to  you.   Any  such
   termination shall  be without liability  of any party  to any  other party,
   except as otherwise provided in Section 5 hereof.

             8.  Indemnifications.  (a)  The Company agrees to indemnify and
                 ----------------
   hold harmless each of  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 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  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 or  arising out of or based upon  statements in or omissions
   from that part  of the  Registration Statement which  shall constitute  the
   Statements  of Eligibility  under the  Trust Indenture  Act of 1939  of the
   Trustees  under the  Indenture; 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  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, 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 of 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, officer  of the
   Company who shall  have signed  the Registration Statement  and person  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.(a)  Termination.  This Agreement may be terminated at any time
                    -----------
   prior to the  Time of Delivery,  in your  absolute discretion, upon  notice
   thereof to the  Company, if prior  to the Time of  Delivery (i) trading  in
   securities  on  the New  York Stock  Exchange,  American Stock  Exchange or
   National Association of Securities Dealers Automated Quotation System shall
   have  been  suspended,  (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 domestic  or international  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 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 sale of the  Securities by you.  This Agreement may  also
   be terminated at any time prior to the 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.

                  -------
   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

   Section 8(c) hereof  shall be delivered or sent by  registered mail to such
   party at its principal executive offices.

   each person  who controls the Company  or any of you,  and their respective
   heirs,  executors, administrators,  successors  and assigns,  and no  other

                                                ____________


   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the Underwriting Agreement, dated
   ___________ (the "Agreement"), between the Company and you of
   ________________ in principal amount of First Mortgage Bonds, _______
   Series due ____ (the "Securities"), issued under the Company's Mortgage and
   Deed of Trust, dated as of July 1, 1946, as supplemented by _________
   indentures supplemental thereto, the latest dated as of _____________, to
   Bankers Trust Company and Stanley Burg, as Trustees (such Mortgage, as so
   supplemented, being hereinafter called the "Indenture"), 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 ______________, 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 "Prospectus"); (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 those Commissions in respect thereto;
   (c) the Restated Articles of Incorporation 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; (d) the
   Indenture; and (e) 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 Bankers Trust Company as to the authentication 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.

             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.   The Indenture has been duly and validly authorized by all
        necessary corporate action, has been duly and validly executed and
        delivered, and is a valid and binding instrument enforceable in
        accordance with its terms, except as limited by bankruptcy,
        insolvency, or other laws affecting the enforcement of mortgagees' and
        other creditors' rights, and conforms to the description thereof
        contained in the Prospectus.

             4.   The Company has good and sufficient title to all the
        properties described in, and as subject to the lien of, the Indenture
        and now owned by it subject only to excepted encumbrances as defined
        in the Indenture, and to minor defects and irregularities customarily
        found in properties of like size and character, which do not
        materially impair the use of the property affected thereby in the
        operation of the business of the Company; the description in the
        Indenture of said properties is adequate to constitute the Indenture a
        lien thereon; and the Indenture 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.

             5.   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 legal, valid and binding obligations of the Company
        enforceable in accordance with their terms, except as limited by
        bankruptcy, insolvency, or other laws affecting the enforcement of
        mortgagees' and other creditors' rights and will be entitled to the
        benefit of the security afforded by the Indenture.

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

             7.   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. 

             8.   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.

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

             10.  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 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.

             11.  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.  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.

             12.  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 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]



                                         ______________



   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the Underwriting Agreement, dated
   ______________ (the "Agreement"), between the Company and you of
   ______________ in principal amount of First Mortgage Bonds, ______ Series
   due ____ (the "Securities"), issued under the Company's Mortgage and Deed
   of Trust, dated as of July 1, 1946, as supplemented by __________
   indentures supplemental thereto, the latest dated as of ____________, to
   Bankers Trust Company and Stanley Burg, as Trustees (such Mortgage, as so
   supplemented, being hereinafter called the "Indenture"), 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") (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 ______________ 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 "Prospectus"); (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 Incorporation 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; (d) the Indenture; and
   (e) 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 certificate of Bankers
   Trust Company as to the authentication 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.   The Indenture has been duly and validly authorized by all
        necessary corporate action, has been duly and validly executed and
        delivered, has been duly qualified under the Trust Indenture Act of
        1939, as amended, and is a valid and binding instrument enforceable in
        accordance with its terms, except as limited by bankruptcy, insolvency
        or other laws affecting enforcement of mortgagees' and other
        creditors' rights. 

             3.   The Securities are legal, valid and binding obligations of
        the Company enforceable in accordance with their terms, except as
        limited by bankruptcy, insolvency or other laws affecting enforcement
        of mortgagees' and other creditors' rights and are entitled to the
        benefit of the security afforded by the Indenture.

             4.   The Indenture and the Securities conform as to legal matters
        with the descriptions 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, the Trust Indenture Act
        of 1939, as amended, 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 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 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
   Registration Statement, as of the date 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 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 (including titles to property and
   franchises and the lien of the Indenture, upon which we do not pass), we

   [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, pursuant to the Underwriting Agreement dated _____, 199_ (the
   "Underwriting Agreement") between Northwest Natural Gas Company, an Oregon
   corporation (the "Company"), and you of $__________ aggregate principal
   amount of First Mortgage Bonds, _____% Series Due ____ (the "Securities"),
   of the Company, issued under the Company's Mortgage and Deed of Trust dated
   as of July 1, 1946, as supplemented by _______ indentures supplemental
   thereto, the latest dated as of _____, 199_ (said Mortgage and Deed of
   Trust, as so supplemented, being herein called the "Mortgage"), to Bankers
   Trust Company (the "Corporate Trustee") and Stanley Burg (successor
   Individual Trustee), as Trustees (the "Trustees").

             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"); the Company's prospectus dated ______, 1994, 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"); and the
   Mortgage.  In addition, we have examined, and have relied as to matters of
   fact upon, the documents delivered to you at the closing (except the
   Securities, 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 Mortgage has been duly authorized, executed and delivered
        by the Company and duly qualified under the Trust Indenture Act of
        1939, as amended (the "Trust Indenture Act"), and, assuming due
        authorization, execution and delivery thereof by the Trustees,
        constitutes a valid and legally binding instrument of the Company
        enforceable against the Company in accordance with its terms.

             3.  The Securities have been duly authorized, executed and issued
        by the Company and, assuming due authentication thereof by the
        Corporate Trustee and upon payment and delivery in accordance with the
        Underwriting Agreement, will constitute valid and legally binding
        obligations of the Company enforceable against the Company in
        accordance with their terms and entitled to the benefits of the
        Mortgage. 

             4.  The statements made in the Prospectus under the captions
        "Description of the New Bonds" and ________, insofar as they purport
        to constitute summaries of the terms of documents referred to therein,
        constitute accurate summaries of the terms of such documents in all
        material respects.
        
             5.  The Underwriting Agreement has been duly authorized, executed
        and delivered by the Company. 

             6.  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 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 Securities to you on the
        terms and conditions set forth in the Underwriting Agreement. 

             Our opinions set forth in paragraphs 2 and 3 above are subject to
   the effects of bankruptcy, insolvency, fraudulent conveyance,
   reorganization, moratorium and other similar laws relating to or affecting
   creditors' rights generally, general equitable principles (whether
   considered in a proceeding in equity or at law) and an implied covenant of
   good faith and fair dealing.  

             All legal proceedings taken by the Company in connection with the
   authorization and delivery of the Securities, 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 Mortgage.

             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 4 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, the
   Trust Indenture 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,
