                                     THE COMPANY

               The Company is principally engaged in the distribution of
          natural gas to customers in western Oregon and southwestern
          Washington, including the Portland metropolitan area.  The
          Company and its predecessors have supplied gas service to the
          public since 1859.  The Company's executive offices are located
          at One Pacific Square, 220 N.W. Second Avenue, Portland, Oregon
          97209.  Its telephone number is 503-226-4211.


                        USE OF PROCEEDS AND FINANCING PROGRAM

               The net proceeds to be received by the Company from the sale
          of the Medium-Term Notes will be added to the general funds of
          the Company and used for corporate purposes, primarily to fund,
          in part, the Company's ongoing utility construction program.

               The Company expects its utility construction expenditures in
          1998 to aggregate $90 million, and in the five-year period, 1998-
          2002, to aggregate between $500 million and $550 million.

               It is estimated that 50% of the funds required for utility
          purposes during the 1998-2002 period will be internally generated
          and that the balance, as well as substantially all of the funds
          required for the refunding of maturing and higher-cost debt, will
          be raised through the sale of equity and debt securities,
          including the Medium-Term Notes, in such amounts and at such
          times as the Company's cash requirements and market conditions
          shall determine.  Approximately $10 million of debt securities
          will mature in each of 1999 and 2000.


                          RATIO OF EARNINGS TO FIXED CHARGES

               The ratios of earnings to fixed charges, calculated
          according to the rules set forth under the Securities Act, for
          the following twelve-month periods were:

               Earnings consist of net income to which has been added taxes
          on income and fixed charges.  Fixed charges consist of interest
          on all indebtedness, amortization of debt expense and discount or
          premium, and the estimated interest portion of rentals charged to
          income.


                                  BOOK-ENTRY SYSTEM

               DTC will act as securities depositary for the Medium-Term
          Notes of each issue. Except under the circumstances described
          below, the Medium-Term Notes will be issued in the form of one or
          more fully registered notes that will be deposited with, or on
          behalf of, DTC or such other depositary as may be subsequently
          designated ("Depositary"), and registered in the name of CEDE &
          Co. (DTC's partnership nominee), or such other Depositary or its
          nominee as may be subsequently designated. 

               So long as the Depositary, or its nominee, is the registered
          owner of the Medium-Term Notes, such Depositary or such nominee,
          as the case may be, will be considered the owner of such
          Medium-Term Notes for all purposes under the Mortgage or the
          Indenture (each as defined below), as the case may be, including
          notices and voting.  Payments of principal of, and premium, if
          any, and interest on, the Medium-Term Notes will be made to the
          Depositary or its nominee, as the case may be, as the registered
          owner of such Medium-Term Notes.  Except as set forth below,
          owners of beneficial interests in Medium-Term Notes will not be
          entitled to have any individual Medium-Term Notes registered in
          their names, will not receive or be entitled to receive physical
          delivery of any such Medium-Term Notes and will not be considered
          the owners of Medium-Term Notes under the Mortgage or the
          Indenture.  Accordingly, each person holding a beneficial
          interest in a Medium-Term Note must rely on the procedures of the
          Depositary and, if such person is not a Direct Participant (as


                                      3
     <PAGE>


          hereinafter defined), on procedures of the Direct Participant
          through which such person holds its interest, to exercise any of
          the rights of the registered owner of such Medium-Term Note.

               If the Depositary is at any time unwilling or unable to
          continue as depositary and a successor depositary is not
          appointed by the Company, individual registered Medium-Term Notes
          will be issued in exchange for the Medium-Term Notes held by the
          Depositary. In addition, the Company, at any time and in its sole
          discretion, may determine not to have the Medium-Term Notes held
          by the Depositary and, in such event, individual registered
          Medium-Term Notes will be issued in exchange for the Medium-Term
          Notes held by the Depositary.  In any such instance, an owner of
          a beneficial interest in the Medium-Term Notes will be entitled
          to physical delivery of individual Medium-Term Notes equal in
          principal amount to such beneficial interest and to have such
          Medium-Term Notes registered in its name. Individual Medium-Term
          Notes so issued will be issued as registered Medium-Term Notes in
          denominations of $1,000 or any amount in excess thereof that is
          an integral multiple of $1,000.

               The following is based solely on information furnished by
          DTC: 

               DTC is a limited-purpose trust company organized under the
          New York Banking Law, a "banking organization" within the meaning
          of the New York Banking Law, a member of the Federal Reserve
          System, a "clearing corporation" within the meaning of the New
          York Uniform Commercial Code, and  a "clearing agency" registered
          pursuant to the provisions of Section 17A of the Exchange Act. 
          DTC holds securities that its participants ("Participants")
          deposit with DTC.  DTC also facilitates the settlement among
          Participants of securities transactions, such as transfers and
          pledges, in deposited securities through electronic computerized
          book-entry changes in Participants' accounts, thereby eliminating
          the need for physical movement of securities certificates. 
          Direct Participants include securities brokers and dealers,
          banks, trust companies, clearing corporations and certain other
          organizations ("Direct Participants").  DTC is owned by a number
          of its Direct Participants and by The New York Stock Exchange,
          Inc., the American Stock Exchange, Inc., and the National
          Association of Securities Dealers, Inc.  Access to the DTC system
          is also available to others such as securities brokers and
          dealers, banks, and trust companies that clear through or
          maintain a custodial relationship with a Direct Participant,
          either directly or indirectly ("Indirect Participants").  The
          rules applicable to DTC and its Participants are on file with the
          Commission.

               Purchases of the Medium-Term Notes under the DTC system must
          be made by or through Direct Participants, which will receive a
          credit for the Medium-Term Notes on DTC's records.  The ownership
          interest of each actual purchaser of each Medium-Term Note
          ("Beneficial Owner") is in turn to be recorded on the Direct and
          Indirect Participants' records.  Beneficial Owners will not
          receive written confirmation from DTC of their purchase, but
          Beneficial Owners are expected to receive written confirmation
          providing details of the transaction, as well as periodic
          statements of their holdings, from the Direct or Indirect
          Participant through which the Beneficial Owner entered into the
          transaction.  Transfers of ownership interests in the Medium-Term
          Notes are to be accomplished by entries made on the books of
          Participants acting on behalf of Beneficial Owners.  Beneficial
          Owners will not receive certificates representing their ownership
          interests in the Medium-Term Notes, except in the event that use
          of the book-entry system for the Medium-Term Notes is
          discontinued.

               To facilitate subsequent transfers, all Medium-Term Notes
          deposited by Participants with DTC are registered in the name of
          CEDE & Co.  The deposit of Medium-Term Notes with DTC and their
          registration in the name of CEDE & Co. effect no change in
          beneficial ownership.  DTC has no knowledge of the actual
          Beneficial Owners of the Medium-Term Notes; DTC's records reflect
          only the identity of the Direct Participants to whose accounts
          such Medium-Term Notes are credited, which may or may not be the
          Beneficial Owners.  The Participants will remain responsible for
          keeping account of their holdings on behalf of their customers.

               Conveyance of notices and other communications by DTC to
          Direct Participants, by Direct Participants to Indirect
          Participants, and by Direct Participants and Indirect
          Participants to Beneficial Owners will be governed by
          arrangements among them, subject to any statutory or regulatory
          requirements as may be in effect from time to time. 

               If the Medium-Term Notes of any issue are redeemable prior
          to the maturity date, redemption notices shall be sent to CEDE &
          Co.  If less than all of the Medium-Term Notes of any issue are
          being redeemed, DTC's practice is to determine by lot the amount
          of the interest of each Direct Participant in such issue to be
          redeemed. 

               Neither DTC nor CEDE & Co. will consent or vote with respect
          to the Medium-Term Notes.  Under its usual procedures, DTC mails
          an Omnibus Proxy to the Company as soon as possible after the
          record date. The Omnibus Proxy assigns CEDE & Co.'s consenting or
          voting rights to those Direct Participants to whose accounts the
          Medium-Term Notes are credited on the record date (identified in
          a listing attached to the Omnibus Proxy).


                                      4
     <PAGE>


               Principal and interest payments on the Medium-Term Notes
          will be made to DTC. DTC's practice is to credit Direct
          Participants' accounts on the date on which interest is payable
          in accordance with their respective holdings shown on DTC's
          records, unless DTC has reason to believe that it will not
          receive payment on such payment date. Payments by Participants to
          Beneficial Owners will be governed by standing instructions and
          customary practices, as is the case with securities held for the
          accounts of customers in bearer form or registered in "street
          name", and will be the responsibility of such Participant and not
          of DTC, the Mortgage Trustees (as defined below), the Indenture
          Trustee (as defined below) or the Company, subject to any
          statutory or regulatory requirements as may be in effect from
          time to time.  Payment of principal and interest to DTC is the
          responsibility of the Company and the Corporate Trustee (as
          defined below) or the Indenture Trustee, as the case may be. 
          Disbursement of such payments to Direct Participants shall be the
          responsibility of DTC, and disbursement of such payments to the
          Beneficial Owners shall be the responsibility of Direct and
          Indirect Participants.

               DTC may discontinue providing services as securities
          depositary with respect to the Medium-Term Notes at any time by
          giving reasonable notice to the Company, the Mortgage Trustees
          and the Indenture Trustee.
                                                       
                              -------------------------

               None of the Company or the Mortgage Trustees or the
          Indenture Trustee will have any responsibility or liability for
          any aspect of the records relating to or payments made on account
          of beneficial interests in the Medium-Term Notes or for
          maintaining, supervising or reviewing any records relating to
          such beneficial interests.


                           DESCRIPTION OF THE SECURED NOTES

          GENERAL

               The Secured Notes, which comprise a series of the Company's
          First Mortgage Bonds ("Bonds"), are to be issued under the
          Company's Mortgage and Deed of Trust, dated as of July 1, 1946,
          to Bankers Trust Company ("Corporate Trustee") and R.G. Page
          (Stanley Burg, successor), as trustees (together, "Mortgage
          Trustees"), as supplemented by twenty supplemental indentures,
          all of which are collectively referred to as the "Mortgage". 

               The statements herein concerning the Secured Notes and the
          Mortgage are merely an outline and do not purport to be complete.
          They make use of terms defined in the Mortgage and are qualified
          in their entirety by express reference to the cited Sections and
          Articles. They may be changed with respect to any Secured Note by
          the applicable Pricing Supplement, which should be read in
          conjunction with this description.

               The Secured Notes will be offered on a continuing basis and
          each Secured Note will mature on such date, not less than nine
          months or more than 30 years from its date of issue, as selected
          by the purchaser and agreed to by the Company. 

               The Pricing Supplement relating to each Secured Note will
          set forth the principal amount, interest rate, interest payment
          dates, record dates, issue price and Agent's commission or
          discount, original issue and maturity dates, redemption or
          repayment provisions, if any, and other material terms of such
          Secured Note. 

          INTEREST

               Unless otherwise specified in the Pricing Supplement
          relating to any Secured Note, interest on such Secured Note will
          be payable semi-annually in arrears on June 1 and December 1 of
          each year and at maturity.

               Unless otherwise specified in the Pricing Supplement
          relating to any Secured Note, interest payable on any interest
          payment date for any Secured Note will be payable to the person
          in whose name such Secured Note is registered on the record date
          with respect to such interest payment date, which shall be the
          May 15 or November 15 (whether or not a business day), as the
          case may be, next preceding such interest payment date; provided
          that, (i) if the original issue date of any Secured Note is after
          a record date and before the corresponding interest payment date,
          such Secured Note shall bear interest from the original issue
          date, but payment of interest shall commence on the second
          interest payment date succeeding the original issue date, and
          (ii) interest payable on the maturity date will be payable to the
          person to whom the principal thereof shall be payable. 

               Unless otherwise indicated in the applicable Pricing
          Supplement, interest on the Secured Notes will be computed on the
          basis of a 360-day year consisting of twelve 30-day months.


                                      5
     <PAGE>


          FORM, EXCHANGE AND PAYMENT

                   The Secured Notes will be issued in fully registered
          form in denominations of $1,000 or any amount in excess thereof
          that is an integral multiple of $1,000. The Secured Notes will be
          exchangeable at the office of Bankers Trust Company in New York
          City, without charge other than taxes or other governmental
          charges incident thereto. Principal, premium, if any, and
          interest will be payable at such office. (See Twentieth
          Supplemental, Sec. 1.01.)  Notwithstanding the foregoing, for so
          long as the Secured Notes shall be held by the Depositary or its
          nominee, owners of beneficial interests in the Secured Notes will
          not be entitled to have any individual Secured Notes registered
          in their names, and transfers of beneficial interests and
          payments of principal, premium, if any, and interest will be made
          as described herein under "Book-Entry System". 

          REDEMPTION

               To the extent, if any, provided in the Pricing Supplement
          relating to any Secured Note, such Secured Note will be
          redeemable, on 30 days' notice, in whole or in part, at any time
          on or after the initial redemption date, if any, fixed at the
          time of sale and set forth in the applicable Pricing Supplement. 
          On or after the initial redemption date, such Secured Note will
          be redeemable in whole or in part, at the option of the Company
          at a redemption price determined in accordance with the following
          paragraph or as set forth in the related Pricing Supplement, plus
          accrued interest to the date fixed for redemption. 

               The redemption price for each Secured Note subject to
          redemption shall, for the twelve-month period commencing on the
          initial redemption date, be equal to a certain percentage of the
          principal amount of such Secured Note and thereafter, shall
          decline for the twelve-month period commencing on each
          anniversary of the initial redemption date by a percentage of
          principal amount ("Reduction Percentage") until the redemption
          price shall be 100% of the principal amount. The initial
          redemption date and price and any Reduction Percentage with
          respect to each Secured Note subject to redemption will be fixed
          at the time of sale and set forth in the applicable Pricing
          Supplement.

               If so specified in the Pricing Supplement relating to any
          Secured Note, the Company may not, prior to the redemption
          limitation date, if any, set forth in such Pricing Supplement,
          redeem such Secured Note as contemplated above as a part of, or
          in anticipation of, any refunding operation by the application,
          directly or indirectly, of moneys borrowed having an effective
          interest cost to the Company (calculated in accordance with
          generally accepted financial practice) of less than the effective
          interest cost to the Company (similarly calculated) of such
          Secured Note. 

               If, at the time the notice of redemption shall be given, the
          redemption money shall not be on deposit with the Corporate
          Trustee, the redemption may be made subject to the receipt of
          such money before the date fixed for redemption, and such notice
          shall be of no effect unless such money shall be so received. 

               Unless otherwise indicated in the applicable Pricing
          Supplement, the Secured Notes will not be subject to any sinking
          fund. 

          REPAYMENT AT OPTION OF HOLDER

               To the extent, if any, provided in the Pricing Supplement
          relating to any Secured Note, such Secured Note will be repayable
          by the Company at the option of the registered holder thereof on
          the date specified in such Pricing Supplement ("Repayment Date"),
          at a price equal to a percentage of the principal amount of such
          Secured Note specified in such Pricing Supplement ("Repayment
          Price"), plus accrued interest to the date of repayment.  For any
          Secured Note to be repaid, the Company must receive such Secured
          Note at its office or agency in the Borough of Manhattan, The
          City of New York (currently, the office of the Corporate
          Trustee), within the period ("Election Period") commencing at the
          opening of business and ending at the close of business on the
          dates specified in the Pricing Supplement relating to such
          Secured Note (provided that, if the last day of the Election
          Period shall not be a business day, the Election Period shall end
          at the close of business on the next succeeding business day),
          together with the form entitled "Option to Elect Repayment" on
          the reverse of, or otherwise accompanying, such Secured Note duly
          completed.  Any such election so received by the Company within
          such Election Period shall be irrevocable.  The repayment option
          may be exercised by the registered holder of a Secured Note for
          less than the entire principal amount of such Secured Note,
          provided that the principal amount to be repaid is equal to
          $1,000 or an integral multiple of $1,000.  All questions as to
          the validity, eligibility (including time of receipt) and
          acceptance of any Secured Note for repayment will be determined
          by the Corporate Trustee, whose determination will be final and
          binding.

               So long as the Depositary or the Depositary's nominee is the
          registered holder of the Secured Notes, the Depositary or such
          nominee will be the only entity that can exercise the repayment
          option, and repayment will be made in accordance with the


                                      6
    <PAGE>


          Depositary's repayment procedures in effect at the time.  See
          "Book-Entry System."  In order to ensure that the Depositary or
          its nominee will timely exercise a repayment option with respect
          to a particular beneficial interest in the Secured Notes, the
          Beneficial Owner of such interest must instruct the broker or
          other Direct or Indirect Participant through which it holds such
          interest to notify the Depositary of its election to exercise the
          repayment option.  In addition, the Beneficial Owner must effect
          delivery of such interest at the time such notice of election is
          given to the Depositary by causing the broker or other Direct or
          Indirect Participant through which it holds such interest to
          transfer such interest on the Depositary's records to the
          Corporate Trustee.  Different firms have different deadlines for
          accepting instructions from their customers and, accordingly,
          each Beneficial Owner should consult the broker or other Direct
          or Indirect Participant through which it holds an interest in the
          Secured Notes in order to ascertain the deadline by which such
          instruction must be given in order for timely notice to be
          delivered to the Depositary.

          PROVISIONS FOR MAINTENANCE OF PROPERTY

               While the Mortgage contains provisions for the maintenance
          of the Mortgaged and Pledged Property, the Mortgage does not
          permit redemption of Bonds pursuant to these provisions.

          SECURITY

               The Secured Notes together with all other Bonds now or
          hereafter issued under the Mortgage will be secured by the
          Mortgage, which constitutes a first mortgage lien on certain gas
          utility properties owned from time to time by the Company (except
          as stated below), subject to (a) leases of minor portions of the
          Company's property to others for uses which do not interfere with
          the Company's business, (b) leases of certain property of the
          Company not used in its gas utility business or the gas by-product
          business, (c) excepted encumbrances, and (d) minor defects and
          encumbrances customarily found in properties of like size and
          character which do not impair the use of such properties by the
          Company. There are excepted from the lien all cash and securities;
          certain equipment, apparatus, materials or supplies; aircraft,
          automobiles and other vehicles; receivables, contracts, leases
          and operating agreements; timber, minerals, mineral rights and
          royalties; and all natural gas and oil production property.

               The Mortgage contains provisions subjecting after-acquired
          property (subject to pre-existing liens) to the lien thereof,
          subject to limitations in the case of consolidation, merger or
          sale of substantially all of the Company's assets.  (See
          Mortgage, Art. XVI.)

               The Mortgage provides that the Mortgage Trustees shall have
          a lien upon the mortgaged property, prior to that of the Bonds,
          for the payment of their reasonable compensation and expenses and
          for indemnity against certain liabilities.  (See Mortgage, Sec.
          96).

          ISSUANCE OF ADDITIONAL BONDS

               Bonds may be issued from time to time on the basis of (1)
          60% of property additions, after adjustments to offset
          retirements (see "Modification of the Mortgage -- Issuance of
          Additional Bonds" below); (2) retirement of Bonds or qualified
          lien bonds; or (3) deposit of cash. With certain exceptions in
          the case of (2) above, the issuance of Bonds is subject to
          adjusted net earnings before income taxes for 12 consecutive
          months out of the preceding 15 months being at least twice the
          annual interest requirements on all Bonds at the time
          outstanding, including the additional issue, and all indebtedness
          of prior rank.

               Property additions generally include gas, electric, steam or
          hot water property or gas by-product property acquired after
          March 31, 1946, but may not include securities, airplanes,
          automobiles or other vehicles, or natural gas transmission lines
          or natural gas and oil production property.  As of June 30, 1998,
          approximately $223 million of property additions (including $72 
          million of property additions previously certified as the basis
          for the issuance of $43 million of the Secured Notes) and $125 
          million of retired Bonds were available for use as the basis for 
          the issuance of Bonds.

               The Mortgage contains certain restrictions upon the issuance
          of Bonds against property subject to liens.  

               The Secured Notes will be issued against property additions
          and retired Bonds.

               (See Mortgage, Secs. 4-7, 20-30 and 46, and Third
          Supplemental, Secs. 3 and 4.)

          RELEASE AND SUBSTITUTION OF PROPERTY

               Property may be released against (1) deposit of cash or, to
          a limited extent, purchase money mortgages, (2) property
          additions, or (3) waiver of the right to issue Bonds without
          applying any earnings test. Cash so deposited and cash deposited


                                      7
     <PAGE>


          against the issuance of additional bonds may be withdrawn upon
          the bases stated in (2) and (3) above.  When property released is
          not funded property, property additions used to effect the
          release may again, in certain cases, become available as credits
          under the Mortgage, and the waiver of the right to issue Bonds to
          effect the release may, in certain cases, cease to be effective
          as such a waiver. Similar provisions are in effect as to cash
          proceeds of such property. The Mortgage contains special
          provisions with respect to qualified lien bonds pledged and the
          disposition of moneys received on pledged prior lien bonds. (See
          Mortgage, Secs. 5, 31, 32, 37, 46 to 50, 59 to 61, 100 and 118.)

          SATISFACTION AND DISCHARGE OF MORTGAGE

               The lien of the Mortgage may be canceled and discharged
          whenever all indebtedness secured by the Mortgage has been paid. 
          Bonds, or any portion of the principal amount thereof, will,
          prior to the maturity thereof, be deemed to have been paid for
          purposes of satisfying the lien of the Mortgage and shall not be
          deemed to be outstanding for any other purpose of the Mortgage if
          there shall have been deposited with the Corporate Trustee either
          (i) moneys in the necessary amount or (ii) (a) direct obligations
          of the government of the United States of America or (b)
          obligations guaranteed by the government of the United States of
          America or (c) securities that are backed by obligations of the
          government of the United States of America as collateral under an
          arrangement by which the interest and principal payments on the
          collateral generally flow immediately through to the holder of
          the security, which in any case are not subject to redemption
          prior to maturity by anyone other than the holders, the principal
          of and the interest on which when due, and without any regard to
          reinvestment thereof, shall be sufficient to pay when due the
          principal of, premium, if any, and interest due and to become due
          on said Bonds or portions thereof on the redemption date or
          maturity date thereof, as the case may be.  (See Mortgage, Sec.
          106 and Thirteenth Supplemental, Sec. 3.02.)

          DEFAULTS AND NOTICE THEREOF

               Defaults are:  default in payment of principal, default for
          60 days in payment of interest or of installments of funds for
          retirement of Bonds; certain defaults with respect to qualified
          lien bonds; certain events in bankruptcy, insolvency or
          reorganization; and default for 90 days after notice in the case
          of a breach of any other covenant.  The Mortgage Trustees may
          withhold notice of default (except in payment of principal,
          interest or any fund for the retirement of Bonds) if they think
          it in the interest of the Bondholders.  (See Mortgage, Secs. 65
          and 66.)

               Holders of 25% of the Bonds may declare the principal and
          the interest due on default, but a majority may annul such
          declaration if such default has been cured.  No holder of Bonds
          may enforce the lien of the Mortgage without giving the Mortgage
          Trustees written notice of a default and unless holders of 25% of
          the Bonds have requested the Mortgage Trustees to act and offered
          them reasonable opportunity to act and the Mortgage Trustees have
          failed to act.  The Mortgage Trustees are not required to risk
          their funds or incur personal liability if there is reasonable
          ground for believing that the repayment is not reasonably
          assured.  Holders of a majority of the Bonds may direct the time,
          method and place of conducting any proceedings for any remedy
          available to the Mortgage Trustees, or exercising any trust or
          power conferred upon the Mortgage Trustees, but the Mortgage
          Trustees are not required to follow such direction if not
          sufficiently indemnified for expenditures.  (See Mortgage, Secs.
          67, 71, 80 and 94.)

          EVIDENCE TO BE FURNISHED TO THE MORTGAGE TRUSTEES

               Compliance with Mortgage provisions is evidenced by written
          statements of the Company's officers or persons selected by the
          Company.  In certain major matters the accountant, engineer,
          appraiser or other expert must be independent.  Various
          certificates and other papers, including an annual certificate
          with reference to compliance with the terms of the Mortgage and
          absence of defaults, are required to be filed annually and upon
          the occurrence of certain events.  (See Mortgage, Secs. 38-46.)

          MODIFICATION OF THE MORTGAGE

               The rights of the Bondholders may be modified with the
          consent of 70% of the Bonds and, if less than all series of Bonds
          are affected, the consent also of 70% of Bonds of each series
          affected.  The Company has the right, without any consent or
          other action by holders of any series of Bonds, to substitute
          66 % for 70%.  In general, no modification of the terms of
          payment of principal and interest, affecting the lien of the
          Mortgage or reducing the percentage required for modification
          (except as provided above) will be effective against any
          Bondholder without his consent.  (See Mortgage, Art. XIX and
          Ninth Supplemental, Sec.6.)

               The Company has reserved the right to amend the Mortgage,
          without any consent or other action by holders of the Bonds of
          the Nineteenth Series or of Bonds of any subsequently created
          series (including the Secured Notes), in the following respects:


                                      8
     <PAGE>

               Release and Substitution of Property

               To permit the release of property at the lesser of its cost
          or its fair value at the time that such property became funded
          property, rather than at its fair value at the time of its
          release; and to facilitate the release of unfunded property. 
          (See Mortgage, Secs. 3, 59 and 60 and Eighteenth Supplemental,
          Sec. 2.03.)

               Issuance of Additional Bonds

               To clarify that (i) for purposes of determining annual
          interest requirements, interest on Bonds or other indebtedness
          bearing interest at a variable interest rate shall be computed at
          the average of the interest rates borne by such Bonds or other
          indebtedness during the period of calculation or, if such Bonds
          or other indebtedness shall have been issued after such period or
          shall be the subject of pending applications, interest shall be
          computed at the initial rate borne upon issuance, and (ii) no
          extraordinary items shall be included in operating expenses or
          deducted from revenues or other income in calculating adjusted
          net earnings (See Mortgage, Sec. 7.); and to revise the basis for
          the issuance of additional Bonds from 60% of property additions,
          after adjustments to offset retirements, to 70%. (See Mortgage,
          Secs. 25, 26, 59 and 61 and Eighteenth Supplemental, Secs. 2.01
          and 2.02.)

          THE CORPORATE TRUSTEE

               Bankers Trust Company also serves as the Indenture Trustee
          under the Indenture under which the Unsecured Notes are issued. 


                          DESCRIPTION OF THE UNSECURED NOTES

              GENERAL

               The Unsecured Notes are to be issued under an Indenture,
          dated as of June 1, 1991 ("Indenture"), between the Company and
          Bankers Trust Company, as trustee ("Indenture Trustee").

               The statements herein concerning the Unsecured Notes and the
          Indenture are merely an outline and do not purport to be
          complete.  They make use of terms defined in the Indenture and
          are qualified in their entirety by express reference to the cited
          Sections and Articles. They may be changed with respect to any
          Unsecured Note by the applicable Pricing Supplement, which should
          be read in conjunction with this description.

               The Indenture provides that debt securities (including the
          Unsecured Notes and including both interest bearing and original
          issue discount securities) may be issued thereunder, without
          limitation as to aggregate principal amount. (See Indenture, Sec.
          301.)  All debt securities heretofore or hereafter issued under
          the Indenture (including the Unsecured Notes) are collectively
          referred to as the "Indenture Securities". The Indenture does not
          limit the amount of other debt, secured or unsecured, which may
          be issued by the Company. The Unsecured Notes will rank pari
          passu with all other unsecured and unsubordinated indebtedness of
          the Company. Substantially all of the gas plants, distribution
          systems and other materially important physical properties of the
          Company are subject to the lien of the Mortgage securing the
          Company's Bonds. (See "Description of the Secured Notes--
          Security" and "-- Issuance of Additional Bonds", above.) 

               The Unsecured Notes will be offered on a continuing basis,
          and each Unsecured Note will mature on such date, not less than
          nine months nor more than 30 years from its date of issue, as
          selected by the purchaser and agreed to by the Company.

               The Pricing Supplement relating to any Unsecured Note will
          set forth the principal amount, interest rate, interest payment
          dates, regular record dates, issue price and Agent's commission
          or discount, original issue and maturity dates, redemption or
          repayment provisions, if any, and other material terms of such
          Unsecured Note. 

          INTEREST

               Unless otherwise specified in the Pricing Supplement
          relating to any Unsecured Note, interest on such Unsecured Note
          will be payable semi-annually in arrears on June 1 and December 1
          of each year and at maturity. 

               Unless otherwise specified in the Pricing Supplement
          relating to any Unsecured Note, interest payable on any interest
          payment date for any Unsecured Note will be payable to the person
          in whose name such Unsecured Note is registered on the record
          date with respect to such interest payment date, which shall be
          the May 15 or November 15 (whether or not a business day), as the


                                      9
     <PAGE>


          case may be, next preceding such interest payment date; provided
          that, (i) if the original issue date of any Unsecured Note is
          after a record date and before the corresponding interest payment
          date, such Unsecured Note will bear interest from the original
          issue date but payment of interest shall commence on the second
          interest payment date succeeding the original issue date, and
          (ii) interest payable on the maturity date will be payable to the
          person to whom the principal thereof shall be payable.

               Unless otherwise indicated in the applicable Pricing
          Supplement, interest on the Unsecured Notes will be computed on
          the basis of a 360-day year consisting of twelve 30-day months. 

          FORM, EXCHANGE AND PAYMENT

               The Unsecured Notes will be issued in fully registered form
          in denominations of $1,000 or any amount in excess thereof that
          is an integral multiple of $1,000. The Unsecured Notes will be
          exchangeable at the office of Bankers Trust Company in New York
          City, without charge other than taxes or other governmental
          charges incident thereto. Principal, premium, if any, and
          interest will be payable at such office. Notwithstanding the
          foregoing, for so long as the Unsecured Notes shall be held by
          the Depositary or its nominee, owners of beneficial interests in
          the Unsecured Notes will not be entitled to have any individual
          Unsecured Notes registered in their names, and transfers of
          beneficial interests and payments of principal, premium, if any,
          and interest will be made as described herein under "Book-Entry
          System". 

          REDEMPTION

               To the extent, if any, provided in the Pricing Supplement
          relating to any Unsecured Note, such Unsecured Note will be
          redeemable, on not less than 30 days' notice, in whole or in
          part, at any time on or after the initial redemption date, if
          any, fixed at the time of sale and set forth in the applicable
          Pricing Supplement.  On or after the initial redemption date,
          such Unsecured Note will be redeemable in whole or in part, at
          the option of the Company, at a redemption price determined in
          accordance with the following paragraph or as set forth in the
          related Pricing Supplement, plus accrued interest to the date
          fixed for redemption.

               The redemption price for each Unsecured Note subject to
          redemption shall, for the twelve-month period commencing on the
          initial redemption date, be equal to a certain percentage of the
          principal amount of such Unsecured Note and, thereafter, shall
          decline for the twelve-month period commencing on each
          anniversary of the initial redemption date by a percentage of
          principal amount ("Reduction Percentage") until the redemption
          price shall be 100% of the principal amount. The initial
          redemption price and date and any Reduction Percentage with
          respect to each Unsecured Note subject to redemption will be
          fixed at the time of sale and set forth in the applicable Pricing
          Supplement.

               If so specified in the Pricing Supplement relating to any
          Unsecured Note, the Company may not, prior to the redemption
          limitation date, if any, set forth in such Pricing Supplement,
          redeem such Unsecured Note as contemplated above as a part of, or
          in anticipation of, any refunding operation by the application,
          directly or indirectly, of moneys borrowed having an effective
          interest cost to the Company (calculated in accordance with
          generally accepted financial practice) of less than the effective
          interest cost to the Company (similarly calculated) of such
          Unsecured Note. 

               If, at the time the notice of redemption shall be given, the
          redemption money shall not be on deposit with the Indenture
          Trustee, the redemption shall be made subject to the receipt of
          such money on or before the date fixed for redemption, and such
          notice shall be of no effect unless such money shall be so
          received. (See Indenture, Art. Four.)

               Unless otherwise indicated in the applicable Pricing
          Supplement, the Unsecured Notes will not be subject to any
          sinking fund.

          REPAYMENT AT OPTION OF HOLDER

               To the extent, if any, provided in the Pricing Supplement
          relating to any Unsecured Note, such Unsecured Note will be
          repayable by the Company at the option of the registered holder
          thereof on the date specified in such Pricing Supplement
          ("Repayment Date"), at a price equal to a percentage of the
          principal amount of such Unsecured Note specified in such Pricing
          Supplement ("Repayment Price"), plus accrued interest to the date
          of repayment.  For any Unsecured Note to be repaid, the Company
          must receive such Unsecured Note at its office or agency in the
          Borough of Manhattan, The City of New York (currently, the office
          of the Indenture Trustee), within the period ("Election Period")
          commencing at the opening of business and ending at the close of
          business on the dates specified in the Pricing Supplement
          relating to such Unsecured Note (provided that, if the last day
          of the Election Period shall not be a business day, the Election
          Period shall end at the close of business on the next succeeding
          business day), together with the form entitled "Option to Elect
          Repayment" on the reverse of, or otherwise accompanying, such
          Unsecured Note duly completed.  Any such election so received by


                                      10
     <PAGE>


          the Company within such Election Period shall be irrevocable. 
          The repayment option may be exercised by the registered holder of
          an Unsecured Note for less than the entire principal amount of
          such Unsecured Note, provided that the principal amount to be
          repaid is equal to $1,000 or an integral multiple of $1,000.  All
          questions as to the validity, eligibility (including time of
          receipt) and acceptance of any Unsecured Note for repayment will
          be determined by the Indenture Trustee, whose determination will
          be final and binding.

               So long as the Depositary or the Depositary's nominee is the
          registered holder of the Unsecured Notes, the Depositary or such
          nominee will be the only entity that can exercise the repayment
          option, and repayment will be made in accordance with the
          Depositary's repayment procedures in effect at the time.  See
          "Book-Entry System."  In order to ensure that the Depositary or
          its nominee will timely exercise a repayment option with respect
          to a particular beneficial interest in the Unsecured Notes, the
          Beneficial Owner of such interest must instruct the broker or
          other Direct or Indirect Participant through which it holds such
          interest to notify the Depositary of its election to exercise the
          repayment option.  In addition, the Beneficial Owner must effect
          delivery of such interest at the time such notice of election is
          given to the Depositary by causing the broker or other Direct or
          Indirect Participant through which it holds such interest to
          transfer such interest on the Depositary's records to the
          Indenture Trustee.  Different firms have different deadlines for
          accepting instructions from their customers and, accordingly,
          each Beneficial Owner should consult the broker or other Direct
          or Indirect Participant through which it holds an interest in the
          Unsecured Notes in order to ascertain the deadline by which such
          instruction must be given in order for timely notice to be
          delivered to the Depositary.

          DEFEASANCE

               The principal amount of any Unsecured Notes issued under the
          Indenture will be deemed to have been paid for purposes of the
          Indenture and the entire indebtedness of the Company in respect
          thereof will be deemed to have been satisfied and discharged, if
          there shall have been irrevocably deposited with the Indenture
          Trustee, in trust: (a) money in an amount which will be
          sufficient, or (b) in the case of a deposit made prior to the
          maturity of the Unsecured Notes, Government Obligations (as
          defined herein), which do not contain provisions permitting the
          redemption or other prepayment thereof at the option of the
          issuer thereof, the principal of and the interest on which when
          due, without any regard to reinvestment thereof, will provide
          moneys which, together with the money, if any, deposited with or
          held by the Indenture Trustee, will be sufficient, or (c) a
          combination of (a) and (b) which will be sufficient, to pay when
          due the principal of and premium, if any, and interest, if any,
          due and to become due on the Unsecured Notes that are
          outstanding.  For this purpose, Government Obligations include
          direct obligations of, or obligations unconditionally guaranteed
          by, the United States of America entitled to the benefit of the
          full faith and credit thereof and certificates, depositary
          receipts or other instruments which evidence a direct ownership
          interest in such obligations or in any specific interest or
          principal payments due in respect thereof.  (See Indenture, Secs.
          101, 701.)

               If the Company shall make any deposit of money and/or
          Government Obligations with respect to the Unsecured Notes, or
          any portion of the principal amount thereof, prior to the
          Maturity or redemption of such Unsecured Notes or such portion of
          the principal amount thereof, for the satisfaction or discharge
          of the indebtedness of the Company in respect to such Unsecured
          Notes or such portion thereof as contemplated by Section 701 of
          the Indenture, the Company shall deliver to the Indenture Trustee
          either (a) an instrument wherein the Company, notwithstanding
          such satisfaction and discharge, shall assume the obligation
          (which shall be absolute and unconditional) to irrevocably
          deposit with the Indenture Trustee such additional sums of money,
          if any, or additional Government Obligations, if any, or any
          combination thereof, at such time or times, as shall be
          necessary, together with the money and/or Government Obligations
          theretofore so deposited, to pay when due the principal of and
          premium, if any, and interest due and to become due on such
          Unsecured Notes or such portions thereof, all in accordance with
          and subject to the provisions of said Section 701; provided,
          however, that such instrument may state that the obligation of
          the Company to make additional deposits as aforesaid shall be
          subject to the delivery to the Company by the Indenture Trustee
          of a notice asserting the amount of such deficiency accompanied
          by an opinion of an independent public accountant of nationally
          recognized standing, selected by the Indenture Trustee, showing
          the calculation thereof, or (b) an opinion of Counsel to the
          effect that the Holders of such Unsecured Notes, or such portions
          of the principal amount thereof, will not recognize income, gain
          or loss for United States federal income tax purposes as a result
          of such satisfaction and discharge and will be subject to United
          States federal income tax on the same amounts, at the same times
          and in the same manner as if such satisfaction and discharge had
          not been effected.

               In the event that the Company shall elect to deliver to the
          Indenture Trustee an instrument as described in clause (a) of the
          preceding paragraph in connection with any such deposit of money
          and/or Government Obligations with the Indenture Trustee, under
          current applicable United States federal income tax regulations,
          the Holders of such Unsecured Notes, or such portions thereof,
          will not recognize income, gain or loss for United States federal
          income tax purposes as a result of such satisfaction and
          discharge and will be subject to United States federal income tax
          on the same amounts, at the same times and in the same manner as
          if such deposit had not been effected.  There can be no assurance
          that such United States federal income tax regulations will not
          change such that, as a result of such deposit and delivery by the


                                      11
     <PAGE>


          Company of such instrument, Holders may recognize income, gain or
          loss for United States federal income tax purposes and may not be
          subject to United States federal income tax on the same amounts,
          at the same times and in the same manner as if such deposit had
          not been effected.

          EVENTS OF DEFAULT AND NOTICE THEREOF

               Events of Default are: default for three Business Days in
          payment of principal; default for 60 days in payment of interest;
          certain events in bankruptcy, insolvency or reorganization;
          default for 90 days after notice in the case of a breach of any
          other covenant; and any other Event of Default specified with
          respect to the Indenture Securities of a particular series. No
          Event of Default with respect to a series of Indenture Securities
          necessarily constitutes an Event of Default with respect to the
          Indenture Securities of any other series. The Indenture Trustee
          may withhold notice of default (except in payment of principal,
          interest or any funds for the retirement of Indenture Securities)
          if it, in good faith, determines that withholding of such notice
          is in the interest of the Holders of the Indenture Securities.
          (See Indenture, Secs. 801 and 903.) 

               Either the Indenture Trustee or the Holders of not less than
          33% in principal amount (or such lesser amount as may be provided
          in the case of discount Indenture Securities) of the outstanding
          Indenture Securities of all defaulted series, considered as one
          class, may declare the principal and interest on such series due
          on default, but the Company may annul such default by effecting
          its cure and paying overdue interest and principal.  No Holder of
          Indenture Securities may enforce the Indenture without having
          given the Indenture Trustee written notice of default, and unless
          the Holders of a majority of the Indenture Securities of all
          defaulted series, considered as one class, shall have requested
          the Indenture Trustee to act and offered reasonable indemnity,
          and for 60 days the Indenture Trustee shall have failed to act. 
          But, each Holder has an absolute right to receive payment of
          principal and interest when due and to institute suit for the
          enforcement of such payment. The Indenture Trustee is not
          required to risk its funds or incur any financial liability if it
          shall have reasonable grounds for believing that repayment is not
          reasonably assured. The Holders of a majority of the Indenture
          Securities of all defaulted series, considered as one class, may
          direct the time, method and place of conducting any proceedings
          for any remedy available to the Indenture Trustee, or exercising
          any trust or power conferred on the Indenture Trustee, with
          respect to the Indenture Securities of such series, but the
          Indenture Trustee is not required to follow such direction if not
          sufficiently indemnified and the Indenture Trustee may take any
          other action it deems proper which is not inconsistent with such
          direction. (See Indenture, Secs. 802, 807, 808, 812 and 902.) 

          EVIDENCE TO BE FURNISHED TO THE INDENTURE TRUSTEE

               Compliance with Indenture provisions will be evidenced by
          written statements of the Company's officers. An annual
          certificate with reference to compliance with the covenants and
          conditions of the Indenture and the absence of defaults is
          required to be filed with the Indenture Trustee. (See Indenture,
          Sec.1004.) 

          MODIFICATION OF THE INDENTURE

               The rights of the Holders of the Indenture Securities may be
          modified with the consent of the Holders of a majority of the
          Indenture Securities of all series or Tranches, as defined below,
          affected, considered as one class. However, certain specified
          rights of the Holders of Indenture Securities may be modified
          without the consent of the Holders if such modification would not
          be deemed adversely to affect their interests in any material
          respect. In general, no modification of the terms of payment of
          principal and interest, no reduction of the percentage in
          principal amount of the Indenture Securities outstanding under
          such series required to consent to any supplemental indenture or
          waiver under the Indenture, no reduction of such percentage
          necessary for quorum and voting, and no modification of certain
          of the provisions in the Indenture relating to supplemental
          indentures, waivers of certain covenants and waivers of past
          defaults is effective against any Holder of Indenture Securities
          without his consent.  "Tranche" means a group of Indenture
          Securities which are of the same series and have identical terms
          except as to principal amount and/or date of issuance.  (See
          Indenture, Art. Twelve.)

          THE INDENTURE TRUSTEE

               Bankers Trust Company also serves as the Corporate Trustee
          under the Mortgage under which the Secured Notes are issued.

                                 PLAN OF DISTRIBUTION

               The Medium-Term Notes are being offered on a continuing
          basis for sale by the Company through the Agents which have
          agreed to use their best efforts to solicit purchases of the
          Medium-Term Notes.  The initial Agents are Merrill Lynch & Co.,
          Merrill Lynch, Pierce, Fenner & Smith Incorporated and
          PaineWebber Incorporated.  Should the Company designate other
          persons to act as Agents, the names of such persons will be
          disclosed in a Pricing Supplement.  The Company will pay each
          Agent a commission which, depending on the maturity of the
          Medium-Term Notes, will range from .125% to .750% of the
          principal amount of any Medium-Term Note sold through such Agent. 
          The Company may also sell Medium-Term Notes to any Agent, as
          principal, at a discount from the principal amount thereof, and
          the Agent may later resell such Medium-Term Notes to investors
          and other purchasers at varying prices related to prevailing
          market prices at the time of resale as determined by such Agent
          or, if so agreed, at a fixed public offering price.  In the case
          of sales to any Agent as principal, such Agent may utilize a
          selling or dealer group in connection with resales.  An Agent may
          sell Medium-Term Notes it has purchased as principal to any
          dealer at a discount and, unless otherwise specified in the
          applicable Pricing Supplement, such discount allowed to any
          dealer will not be in excess of the discount to be received by
          such Agent from the Company.  After the initial public offering
          of Medium-Term Notes to be resold to investors and other
          purchasers, the public offering price (in the case of a fixed
          price public offering), concession and discount may be changed. 
          The Medium-Term Notes also may be sold by the Company directly to
          purchasers.  No commission will be payable to the Agents on
          Medium-Term Notes sold directly by the Company.

               The Company reserves the right to withdraw, cancel or modify
          the offer made hereby without notice and may reject, in whole or
          in part, offers to purchase Medium-Term Notes whether placed
          directly with the Company or through one of the Agents.  Each
          Agent will have the right, in its discretion reasonably
          exercised, to reject any offer to purchase Medium-Term Notes
          received by it, in whole or in part.

               Payment of the purchase price of the Medium-Term Notes will
          be required to be made in immediately available funds in New York
          City on the date of settlement.

               No Medium-Term Note will have an established trading market
          when issued.  The Medium-Term Notes will not be listed on any
          securities exchange.  Each of the Agents may from time to time
          purchase and sell Medium-Term Notes in the secondary market, but
          is not obligated to do so.  There can be no assurance that there
          will be a secondary market for the Medium-Term Notes or liquidity
          in the secondary market if one develops.  From time to time, each
          of the Agents may make a market in the Medium-Term Notes.

               The Agents may be deemed to be "underwriters" within the
          meaning of the Securities Act. The Company has agreed to
          indemnify each of the Agents against, or to make contributions
          relating to, certain liabilities, including liabilities under
          such Act.  The Company has agreed to reimburse each of the Agents
          for certain expenses.  Each of the Agents may engage in
          transactions with, or perform services for, the Company in the
          ordinary course of business.

               In connection with certain types of offers and sales of
          Medium-Term Notes, rules of the Securities and Exchange
          Commission permit the Agents to engage in certain transactions
          that stabilize the price of such Medium-Term Notes.  Such
          transactions consist of bids or purchases for the purpose of
          pegging, fixing or maintaining the price of the Medium-Term
          Notes.

               If the Agents create a short position in any Medium-Term
          Notes in connection with certain types of offers and sales, i.e.,
          if they sell more Medium-Term Notes than are set forth in the
          applicable Pricing Supplement, the Agents may reduce that short
          position by purchasing Medium-Term Notes in the open market.

               In connection with certain types of offers and sales, the
          Agents may also impose a penalty bid on certain Agents and
          selling group members.  This means that if the Agents purchase
          Medium-Term Notes in the open market to reduce the Agents' short
          position or to stabilize the price of the Medium-Term Notes, they
          may reclaim the amount of selling concession from the Agents and
          selling group members who sold these Medium-Term Notes as part of
          the offering.

               In general, purchases of a security for the purpose of
          stabilization or to reduce a short position could cause the price
          of the security to be higher than it might be in the absence of
          such purchases.  The imposition of a penalty bid might also have
          an effect on the price of a security to the extent that it were
          to discourage resales of the security.

               Neither the Company nor any Agent makes any representation
          or prediction as to the direction or magnitude of any effect that
          the transactions described above may have on the price of the
          Medium-Term Notes.  In addition, neither the Company nor any
          Agent makes any representation that the Agents will engage in
          such transactions or that such transactions, once commenced, will
          not be discontinued without notice.

          ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Oregon Business Corporation Act (the "Act") provides, in
          general, that a director or officer of a corporation who has been
          or is threatened to be made a defendant in a legal proceeding
          because that person is or was a director or officer of the
          corporation:

          (1)  shall be indemnified by the corporation for all expenses of
          such litigation when the director or officer is wholly successful
          on the merits or otherwise;

          (2)  may be indemnified by the corporation for the expenses,
          judgments, fines and amounts paid in settlement of such
          litigation (other than a derivative lawsuit) if he or she acted
          in good faith and in a manner reasonably believed to be in, or at
          least not opposed to, the best interests of the corporation (and,
          in the case of a criminal proceeding, had no reasonable cause to
          believe the conduct was unlawful); and

          (3)  may be indemnified by the corporation for expenses of a
          derivative lawsuit (a suit by a shareholder alleging a breach by
          a director or officer of a duty owed to the corporation) if he or
          she acted in good faith and in a manner reasonably believed to be
          in, or at least not opposed to, the best interests of the
          corporation, provided the director or officer is not adjudged
          liable to the corporation.

          The Act also authorizes the advancement of litigation expenses to
          a director or officer upon receipt of a written affirmation of
          the director's or officer's good faith belief that the standard
          of conduct in Section (2) or (3) above has been met and an
          undertaking by such director or officer to repay such expenses if
          it is ultimately determined that he or she did not meet that
          standard and, therefore, is not entitled to be indemnified.  The
          Act also provides that the indemnification provided thereunder
          shall not be deemed exclusive of any other rights to which those
          indemnified may be entitled under any bylaw, agreement, vote of
          shareholders or disinterested directors or otherwise.

          The Company's Bylaws provide that the Company shall indemnify
          directors and officers to the fullest extent permitted under the
          Act, thus making mandatory the discretionary indemnification
          authorized by the Act.

          The Company's Restated Articles of Incorporation provide that the
          Company shall indemnify its officers and directors to the fullest
          extent permitted by law, which may be broader than the
          indemnification authorized by the Act.

          The Company's shareholders have approved and the Company has
          entered into indemnity agreements with its directors and officers
          which provide for indemnity to the fullest extent permitted by
          law and also alter or clarify the statutory indemnity in the
          following respects:

          (1)  prompt advancement of litigation expenses is provided if the
          director or officer makes the required affirmation and
          undertaking;

          (2)  the director or officer is permitted to enforce the
          indemnity obligation in court and the burden is on the Company to
          prove that the director or officer is not entitled to
          indemnification;


                                      II-1
     <PAGE>


          (3)  indemnity is explicitly provided for judgments and
          settlements in derivative actions;

          (4)  prompt indemnification is provided unless a determination is
          made that the director or officer is not entitled to
          indemnification; and

          (5)  partial indemnification is permitted if the director or
          officer is not entitled to full indemnification.

          The Company maintains in effect a policy of insurance providing
          for reimbursement to the Company of payments made to directors
          and officers as indemnity for damages, judgments, settlements,
          costs and expenses incurred by them which the Company may be
          required or permitted to make according to applicable law, common
          or statutory, or under provisions of its Restated Articles of
          Incorporation, Bylaws or agreements effective under such laws.

          ITEM 16. LIST OF EXHIBITS.

          Reference is made to the Exhibit Index on page II-5 hereof.

          ITEM 17.  UNDERTAKINGS.

          The undersigned registrant hereby undertakes:

          (1)   To file, during any period in which offers or sales are
          being made, a post-effective amendment to this registration
          statement:

             (i)   To include any prospectus required by Section 10(a)(3)
             of the Securities Act of 1933;

             (ii)  To reflect in the prospectus any facts or events arising
             after the effective date of the registration statement (or the
             most recent post-effective amendment thereof) which, indivi-
             dually or in the aggregate, represent a fundamental change in
             the information set forth in the registration statement;

             (iii) To include any material information with respect to the
             plan of distribution not previously disclosed in the
             registration statement or any material change to such
             information in the registration statement;

          provided, however, that the undertakings set forth in paragraphs
          (i) and (ii) above do not apply if the registration statement is
          on Form S-3 and the information required to be included in a
          post-effective amendment by those paragraphs is contained in
          periodic reports filed by the registrant pursuant to section 13
          or section 15(d) of the Securities Exchange Act of 1934 that are
          incorporated by reference in this registration statement.

          (2)   That, for the purpose of determining liability under the
          Securities Act of 1933, each such post-effective amendment that
          contains a form of prospectus shall be deemed to be a new
          registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall
          be deemed to be the initial bona fide offering thereof.

          (3)   To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain
          unsold at the termination of the offering.

          The undersigned registrant hereby undertakes, that for purposes
          of determining any liability under the Securities Act of 1933,
          each filing of the registrant's annual report pursuant to section
          13(a) or 15(d) of the Securities Exchange Act of 1934 that is
          incorporated by reference in the registration statement shall be
          deemed to be a new registration statement relating to the
          securities offered therein and the offering of such securities at
          that time shall be deemed to be the initial bona fide offering
          thereof.

          Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to directors, officers
          and controlling persons of the registrant pursuant to the
          provisions described under Item 15 of this registration
          statement, or otherwise, the registrant has been advised that in
          the opinion of the Securities and Exchange Commission such
          indemnification is against public policy as expressed in the
          Securities Act of 1933 and is, therefore, unenforceable.  In the
          event that a claim for indemnification against such liabilities
          (other than the payment by the registrant of expenses incurred or
          paid by a director, officer or controlling person of the
          registrant in the successful defense of any action, suit or
          proceeding) is asserted by such director, officer or controlling
          person in connection with the securities being registered, the
          registrant will, unless in the opinion of its counsel the matter
          has been settled by controlling precedent, submit to a court of
          appropriate jurisdiction the question whether such indem-
          nification by it is against public policy as expressed in the
          Securities Act of 1933 and will be governed by the final
          adjudication of such issue.

          Dear Sirs:

                    Northwest Natural Gas Company, an Oregon corporation
          (the "Company"), proposes to issue and sell from time-to-time not
          to exceed $143,000,000 of its First Mortgage Bonds, designated
          Secured Medium-Term Notes, Series B (the "Secured Notes"), and
          its Unsecured Medium-Term Notes, Series B (the "Unsecured Notes",
          and, together with the Secured Notes, the "Securities").  The
          Secured Notes will be issued under the Company's Mortgage and
          Deed of Trust, dated as of July 1, 1946, to Bankers Trust Company
          (the "Mortgage Trustee" or the "Trustee") and R.G. Page (Stanley
          Burg, successor), as trustees, as supplemented (such Mortgage and
          Deed of Trust as supplemented being hereinafter referred to as
          the "Mortgage" or the "Indenture").  The Unsecured Notes will be
          issued under an indenture, dated as of June 1, 1991 (the "Note
          Indenture" or the "Indenture"), between the Company and Bankers
          Trust Company, as trustee (the "Indenture Trustee" or the
          "Trustee").  The Securities shall have the maturities, interest
          rates, if any, redemption provisions and other terms set forth in
          the Prospectus referred to below, as it may be amended or
          supplemented from time-to-time.  The Securities will be issued,
          and the terms thereof established, from time-to-time, by the
          Company in accordance with the respective Indentures.

                    The Company represents, warrants, covenants and agrees
          with each of you and with each other person which shall become a
          party to this agreement (individually, an "Agent", and
          collectively, the "Agents") and each Agent, severally and not
          jointly, covenants and agrees with the Company as follows:

                    1.   Representations and Warranties of the Company. 
                         ---------------------------------------------
          The Company represents and warrants to each Agent that:

                    (a)  The Company is a corporation duly organized and
               validly existing in good standing under the laws of the
               State of Oregon, and is qualified to do business and is in
               good standing as a foreign corporation in the State of
               Washington, with power (corporate and other) to own its
               properties and conduct its business as described in the
               Prospectus referred to below.

                    (b)  An initial registration statement on Form S-3
               (Registration No. 333-15323) (the "Initial Registration
               Statement") in respect of $150,000,000 aggregate principal
               amount of the Company's First Mortgage Bonds designated
               Secured Medium-Term Notes Series B, and Unsecured Medium-
               Term Notes Series B (of which $43,000,000 remain unsold on
               the date hereof) has been filed with the Securities and
               Exchange Commission (the "Commission") under the Securities
               Act of 1933, as amended (the "Act"), in the form heretofore
               delivered (excluding the exhibits thereto but including the
               documents incorporated by reference in the prospectus
               included therein) to such Agent, and such Initial Registra-
               tion Statement in such form has been declared effective by
               the Commission and no stop order suspending its
               effectiveness has been issued and no proceeding for that
               purpose has been initiated or threatened by the Commission. 
               A subsequent registration statement on Form S-3
               (Registration No. 333- . ), as amended (the "Subsequent
               Registration Statement"), in respect of an additional

               form heretofore delivered or to be delivered (excluding the
               exhibits thereto but including the documents incorporated by
               reference in the prospectus included therein) to such Agent,
               and such Subsequent Registration Statement in such form has
               been declared effective by the Commission and no stop order
               suspending its effectiveness has been issued and no
               proceeding for that purpose has been initiated or threatened
               by the Commission (any preliminary prospectus included in
               the Subsequent Registration Statement being hereinafter
               called a "Preliminary Prospectus").  The Initial
               Registration Statement and the Subsequent Registration
               Statement, including all exhibits thereto but excluding
               Forms T-1 and T-2, as amended at the time each became
               effective, are hereinafter called the "Registration
               Statement"; the combined prospectus included as a part of
               the Subsequent Registration Statement (including, if
               applicable, any prospectus supplement) relating to the
               Securities, in the form in which it most recently has been
               filed with the Commission on or prior to the date of this
               Agreement, is hereinafter called the "Prospectus"; any
               reference herein to any Preliminary Prospectus or the
               Prospectus shall be deemed to refer to and include the
               documents filed by the Company under the Securities Exchange
               Act of 1934, as amended (the "Exchange Act"), and incorpor-
               ated therein by reference as of the date of such Preliminary
               Prospectus or Prospectus; any reference to any amendment or
               supplement to any Preliminary Prospectus or Prospectus,
               including any supplement to the Prospectus that sets forth
               only the terms of a particular issue of the Securities (a
               "Pricing Supplement"), shall be deemed to refer to and
               include the documents filed by the Company under the
               Exchange Act and incorporated therein by reference as of the
               date of such amendment or Pricing Supplement; and any refer-

               deemed to refer to and include the Prospectus as then
               amended or supplemented (including the applicable Pricing
               Supplement) in relation to a particular issue of Securities,
               in the form filed with the Commission pursuant to Rule
               424(b) under the Act, including any documents filed by the
               Company under the Exchange Act and incorporated therein by
               reference as of the date of such amendment or supplement.

                    (c)  The documents incorporated by reference in the
               Prospectus, when filed with the Commission or, if later,
               when they became effective, conformed in all material
               respects with the requirements of the Act or the Exchange
               Act, as applicable, and the applicable rules and regulations
               of the Commission thereunder; none of such documents when so
               filed or when such documents became effective, as the case
               may be, included an untrue statement of a material fact or
               omitted to state a material fact required to be stated
               therein or necessary to make the statements therein, in the

               thereto, when filed with the Commission or, if later, when
               effective, will conform in all material respects with the
               applicable requirements of the Act or the Exchange Act, as
               applicable, and the rules and regulations of the Commission
               thereunder, and when such documents are filed or become
               effective, as the case may be, they will not contain an
               untrue statement of a material fact or omit to state a
               material fact required to be stated therein or necessary to
               make the statements therein, in the light of the
               circumstances under which they were made, not misleading;
               provided, however, that the Company makes no representations
               --------  -------
               or warranties as to information contained in or omitted from
               the Prospectus as amended or supplemented in reliance upon

               the Company by any Agent specifically for use therein;

                    (d)  The Initial Registration Statement and the
               Subsequent Registration Statement when each became effective
               conformed, and the Prospectus conforms, and any amendment or
               supplement thereto will conform, in all material respects,

               of 1939, as amended (the "Trust Indenture Act"), and the
               rules and regulations of the Commission thereunder; and the
               Initial Registration Statement and the Subsequent Registra-
               tion Statement when each became effective did not, the
               Prospectus does not (and on each of the dates referred to in
               clause (i) of Section 6 will not) and any amendment or
               supplement to the Prospectus, as of its date and on each of
               the dates referred to in clause (i) of Section 6, will not,
               contain an untrue statement of a material fact or omit to
               state a material fact required to be stated therein or
               necessary to make the statements therein not misleading;
               provided, however, that the Company makes no 
               --------  -------
               representations or warranties as to information contained in
               or omitted from any such document in reliance upon and in
               conformity with information furnished in writing to the
               Company by any Agent specifically for use therein;

                    (e)  Except as set forth in or contemplated by the
               Prospectus, since the date as of which information is given
               in the Prospectus (i) there has not been any material

               transactions in the ordinary course of business, and (iii)
               neither the Company nor any of its subsidiaries has incurred
               any contingent obligation which is material to the Company
               and its subsidiaries taken as a whole;

                    (f)  The Securities have been duly authorized, and,
               when issued pursuant to their respective Indentures and

               principles of equity relating to or affecting generally the
               enforcement of creditors' rights, including without
               limitation, bankruptcy and insolvency laws, and will be
               entitled to the benefits provided by their respective Inden-

               Trust Indenture Act, constitute valid and legally binding
               instruments, enforceable in accordance with their terms,

               provisions of any statute or the Restated Articles of
               Incorporation, as amended, or the Bylaws, as amended, of the
               Company or any order, rule or regulation of any court or any
               regulatory authority or other governmental agency or body
               having jurisdiction over the Company or any of its
               properties; and no consent, approval, authorization, order,
               registration or qualification of or with any court or
               governmental agency or body is required for the solicitation
               of offers to purchase Securities and the issue and sale of
               the Securities or the consummation by the Company of the
               other transactions contemplated by the Indentures, this
               Agreement or any Terms Agreement, except such as have been
               obtained at or prior to the Commencement Date (as defined in
               Section 4 hereof), will have been obtained under the Act,
               the Trust Indenture Act and the public utility laws of the
               States of Oregon and Washington and such as may be required
               under state securities or Blue Sky laws in connection with
               the solicitation by such Agent of offers to purchase
               Securities from the Company and with purchases of Securities
               by such Agent as principal, as the case may be, in each case
               in the manner contemplated hereby;  and

                    (h)  Other than as set forth or contemplated in the
               Prospectus, there are no legal or governmental proceedings
               pending to which the Company is a party or to which any
               property of the Company is subject, which, if determined ad-
               versely to the Company, would individually or in the
               aggregate have a material adverse effect on the consolidated
               financial position, stockholders' equity or consolidated
               results of operations of the Company, and, to the best of
               the Company's knowledge, no such proceedings are threatened.

                    2.   Obligations of the Agents and the Company.
                         -----------------------------------------
                    (a)  Subject to the terms and conditions hereof and to
               the reservation by the Company of the right to sell
               Securities directly on its own behalf, the Company hereby
               (i) appoints each of Merrill Lynch & Co., Merrill Lynch,
               Pierce, Fenner & Smith Incorporated and PaineWebber
               Incorporated as an agent of the Company for the purpose of
               soliciting and receiving offers to purchase Securities from
               the Company and (ii) reserves the right, from time to time,
               to appoint additional agents for the purpose of soliciting
               and receiving offers to purchase Securities from the
               Company; provided that each such additional agent shall be
               required to become a party to this Agreement and undertake
               the obligations of an Agent hereunder pursuant to an
               Additional Agent Appointment Agreement ("Additional Agent
               Appointment Agreement") substantially in the form of Exhibit
               1 hereto.

                    (b)  On the basis of the representations and warranties
               herein, and subject to the terms and conditions hereof, each
               of the Agents, as agent of the Company, severally and not
               jointly, agrees to use its reasonable best efforts to
               solicit and receive offers to purchase particular issues of
               the Securities from the Company upon the terms and
               conditions set forth in the Prospectus as amended or
               supplemented with respect thereto.  Each Agent will promptly
               advise the Company by telephone or other appropriate means
               of all reasonable offers to purchase Securities, other than
               those rejected by such Agent.  The Company shall not,
               without the consent of each Agent, which consent shall not
               unreasonably be withheld, solicit or accept offers to
               purchase, or sell, any debt securities with a maturity, at
               the time of original issuance, of from nine months to 30
               years, except (i) pursuant to this Agreement, (ii) pursuant
               to a private placement not constituting a public offering
               under the Act, or (iii) in connection with a firm commitment
               underwriting pursuant to an underwriting agreement that does
               not provide for a continuous offering.  However, the
               Company, subject to Section 5(f) hereof, reserves the right
               to sell, and may solicit and accept offers to purchase,
               Securities directly on its own behalf, and, in the case of
               any such sale not resulting from a solicitation made by an
               Agent, no commission will be payable with respect to such
               sale.

                    (c)  Procedural details relating to the issue and
               delivery of Securities, the solicitation of offers to
               purchase Securities and the payment therefor, unless an
               Agent and the Company shall otherwise agree, shall be as set
               forth in the Administrative Procedure attached hereto as
               Annex I (the "Administrative Procedure").  The provisions of
               the Administrative Procedure shall apply to all transactions
               contemplated hereunder other than those made pursuant to a
               Terms Agreement.  Each Agent and the Company shall perform
               the respective duties and obligations specifically provided
               to be performed by each of them in the Administrative
               Procedure.  The Company will furnish to the Trustees a copy
               of the Administrative Procedure as from time to time in
               effect.

                    (d)  The Company reserves the right, in its sole
               discretion, to instruct the Agents to suspend, at any time,
               for any period of time or permanently, the solicitation of
               offers to purchase the Securities.  As soon as practicable,
               but in any event not later than one business day after
               receipt of notice from the Company, the Agents will suspend
               solicitation of offers to purchase Securities from the
               Company until such time as the Company has advised the
               Agents that such solicitation may be resumed.

                    (e)  The Company agrees to pay each Agent a commission,
               at the time of settlement (each a "Settlement Date") of any
               sale of a Security by the Company as a result of a
               solicitation made by such Agent, in an amount equal to the
               following applicable percentage of the principal amount of
               such Security sold:

                                                    Commission
                                         (percentage of aggregate principal
               Range of Maturities           amount of Securities sold)
               -------------------           --------------------------

          From 9 months to less than 1 year                 .125%
          From 1 year to less than 18 months                .150%
          From 18 months to less than 2 years               .200%
          From 2 years to less than 3 years                 .250%
          From 3 years to less than 4 years                 .350%
          From 4 years to less than 5 years                 .450%
          From 5 years to less than 6 years                 .500%
          From 6 years to less than 7 years                 .550%
          From 7 years to less than 10 years                .600%
          From 10 years to less than 15 years               .625%
          From 15 years to less than 20 years               .675%
          From 20 years to 30 years                         .750%


                    3.   Sales to Agents as Principal.  Each sale of
                         ----------------------------
          Securities to an Agent, as principal, shall be made in accordance
          with the terms of this Agreement and (unless the Company and such
          Agent shall otherwise agree) a separate agreement (each a "Terms
          Agreement"), which will provide for the sale of such Securities
          to, and the purchase thereof by, such Agent, as principal.  A
          Terms Agreement may be either (i) a written agreement
          substantially in the form of Annex II hereto, or (ii) an oral
          agreement between either Agent and the Company confirmed in
          writing by such Agent.  A Terms Agreement may also specify
          certain provisions relating to the reoffering of such Securities
          by such Agent.  Each Terms Agreement shall specify the principal
          amount of Securities to be purchased by an Agent pursuant
          thereto, the price to be paid to the Company for such Securities,
          any provisions relating to the rights of, and defaults by, any
          underwriters acting together with such Agent in the reoffering of
          the Securities, the time and date of delivery of and payment for
          such Securities (each, a "Time of Delivery") and place of
          delivery of such Securities, and any requirements for opinions of
          counsel, accountants' letters and officers' certificates pursuant
          to Section 5 hereof.  Each purchase of Securities, unless
          otherwise agreed shall be at a discount equivalent to the
          commission payable to an Agent, acting as agent, with respect to
          a sale of Securities of identical maturity, as set forth in
          Section 2(e) hereof).  The Agent may engage the services of any
          other broker or dealer in connection with the resale of the
          Securities purchased as principal and may allow any portion of
          the discount received in connection with such purchase from the
          Company to be paid to such brokers and dealers.  The commitment
          of an Agent to purchase Securities as principal, whether pursuant
          to a Terms Agreement or otherwise, shall be deemed to have been
          made on the basis of the representations and warranties of the
          Company herein contained and, to the extent not otherwise agreed
          upon in a Terms Agreement or otherwise, shall be subject to the
          terms and conditions herein set forth.

                    4.   Commencement.  At 11:00 a.m., New York City time,

                         ------------------------
          and agrees with each Agent:

                    (a)  (i)  To make no amendment or supplement to the

               Company promptly after receipt of the proposed form thereof
               or (B) after the date of any agreement by such Agent,

               connection with the offering or sale of the Securities, and
               during such same period to advise such Agent, promptly after
               the Company receives notice thereof, of the time when any

               best efforts to obtain its withdrawal;

                    (b)  From time-to-time, to take such action as such
               Agent reasonably may request to qualify the Securities for
               offering and sale under the securities laws of such
               jurisdictions as may be approved by the Company and to
               comply with such laws so as to permit the continuance of
               sales and dealings therein for as long as may be necessary
               to complete the distribution or sale of the Securities;
               provided, however, that in connection therewith the Company
               --------  -------
               shall not be required to qualify as a foreign corporation or
               to file a general consent to service of process in any
               jurisdiction, or to comply with any other requirement rea-
               sonably deemed by the Company to be unduly burdensome;
               provided, further, that the provisions of this subsection
               --------  -------
               (b) shall not apply so long as the Securities are "covered
               securities" within the meaning of Section 18 of the Act and
               any rules and regulations thereunder;

                    (c)  To furnish such Agent with copies of the
               Registration Statement, each amendment thereto, the
               Prospectus and each amendment or supplement thereto, other
               than any Pricing Supplement (except as provided in the
               Administrative Procedure), in the form in which it is filed
               with the Commission pursuant to Rule 424(b) under the Act,

               therein (other than exhibits incorporated by reference in
               the Registration Statement), each in such quantities as such

               other agreement and such Agent requests an opinion or
               opinions by Simpson Thacher & Bartlett, counsel to the
               Agents, or other counsel to the Agents reasonably satisfac-

               supplemented to the date of such letter, with such changes
               as may be necessary to reflect changes in the financial

               statements and other information are available as of a date
               not more than five business days prior to the date of such
               letter;

               pay for such Securities if, at the Settlement Date for such
               Securities, any condition set forth in Section 6 hereof
               shall not have been satisfied (it being understood that the
               judgment of such person with respect to the impracticability
               or inadvisability of such purchase of Securities shall be
               substituted, for purposes of this Section 5(k), for the
               judgment of such Agent with respect thereto); and

               supplements thereto and the mailing and delivering of copies
               thereof to such Agent; (ii) the fees and expenses of counsel
               for the Agents in connection with the establishment of the
               program contemplated hereby, any opinions to be rendered by
               such counsel hereunder and the transactions contemplated

               Indenture and the Securities; (ix) any advertising expenses
               connected with the solicitation of offers to purchase and
               the sale of Securities so long as such advertising expenses

               and expenses incident to the performance of the Company's
               obligations hereunder which are not otherwise specifically
               provided for in this Section; provided, however, that,
               except as provided in Sections 8 and 9 hereof, such Agent
               shall pay all other expenses it incurs, including any
               expenses that may be incurred by it or for its account
               pursuant to the proviso of Section 5(c) hereof.

               of a notice of any intended or potential downgrading, of the
               ratings of the Securities by either Moody's Investors

                    6.   Conditions to Agents' Obligations.  The obligation
                         ---------------------------------
          of an Agent, as agent of the Company, at any time (each a
          "Solicitation Time"), to solicit offers to purchase the
          Securities and the obligation of an Agent to purchase Securities
          as principal, pursuant to a Terms Agreement or otherwise, shall
          be subject, in such Agent's discretion, to the conditions that: 
          (i) all of the representations and warranties of the Company
          herein (and, in the case of an obligation of an Agent under a
          Terms Agreement or other agreement with an Agent to purchase
          Securities as principal, in or incorporated in such agreement by
          reference) were true and correct (A) on the Commencement Date;
          (B) each time that the Registration Statement or the Prospectus
          shall be amended or supplemented, (C) each time a document
          incorporated by reference in the Prospectus as amended or
          supplemented shall be filed by the Company under the Act or
          Exchange Act, (D) at the date of each acceptance by the Company
          of an offer to purchase Securities procured by such Agent, as
          agent, and each agreement by the Company, pursuant to a Terms
          Agreement or otherwise, to sell Securities to an Agent, as
          principal, (E) at each Settlement Date, and (F) at each Time of
          Delivery of Securities so to be purchased by such Agent, as
          principal, as the case may be, (ii) prior to such Solicitation
          Time or such Time of Delivery, as the case may be, the Company
          shall have performed all of its obligations hereunder theretofore
          to be performed, (iii) all requests for additional information on
          the part of the Commission shall have been complied with to the
          reasonable satisfaction of such Agent, (iv) there shall be in
          full force and effect orders of the Public Utility Commission of
          Oregon and the Washington Utilities and Transportation Commission
          which are acceptable to the Agents and which permit the issuance
          and sale of the Securities substantially in accordance with the
          terms and conditions of this Agreement, (v) no stop order
          suspending the effectiveness of the Registration Statement shall
          have been issued and no proceedings for that purpose shall be
          pending before, or to the knowledge of the Company contemplated
          by, the Commission, and (vi) there shall not have occurred:  (A)
          a suspension or material limitation of trading in securities
          generally on the New York Stock Exchange or in any securities of
          the Company on the Nasdaq National Market or any relevant
          exchange; (B) a general moratorium on commercial banking
          activities in New York declared by either Federal or New York
          State authorities; (C) an engagement by the United States in
          hostilities or any escalation of hostilities, the effect of
          which, in the judgment of such Agent, makes it impracticable or
          inadvisable to proceed with the solicitation of offers to
          purchase Securities or the purchase of Securities from the
          Company as principal on the terms and in the manner contemplated
          by this Agreement and, if applicable, any Terms Agreement or
          other agreement; or (D) any downgrading, or any notice shall have
          been given of any intended or potential downgrading, of the
          Securities by either Moody's Investors Service or Standard &
          Poor's Corporation.  In addition to the foregoing, the obligation
          of an Agent to purchase Securities as principal, pursuant to a
          Terms Agreement or other agreement, shall be subject, in such
          Agent's discretion, to the further condition that there shall not
          have been, since the date of such Terms Agreement or other
          agreement or since the respective dates as of which information
          is given in the Registration Statement, any material adverse
          change in the condition, financial or otherwise, or in the
          earnings, business affairs or business prospects of the Company
          and its subsidiaries considered as one enterprise, whether or not
          arising in the ordinary course of business.

                    7.   Conditions to Company's Obligations.
                         -----------------------------------

                    (a)  The obligation of the Company to sell and deliver
               any Security pursuant hereto, to a Terms Agreement or
               otherwise shall be subject to the condition that, after the
               acceptance by the Company of an offer to purchase such
               Security procured by an Agent, as agent, or the agreement by
               the Company, pursuant to a Terms Agreement or otherwise, to
               sell such Security to an Agent, as principal, and prior to
               the Time of Delivery or the Settlement Date, as the case may
               be, with respect to such purchase or sale, neither the
               Public Utility Commission of Oregon nor the Washington
               Utilities and Transportation Commission shall have issued an
               order revoking its then existing order permitting the
               issuance and sale of the Securities through each Agent, as
               agent, on the terms set forth herein or to each Agent, as
               principal, pursuant to a Terms Agreement or other agreement.

                    (b)  If the condition specified in Section 7(a) hereof
               shall not have been fulfilled, the obligation of the Company
               to sell Securities hereunder or under a Terms Agreement or
               other agreement may be terminated by the Company; and
               neither the Company nor any Agent shall have any liability
               to the other, except for (i) the obligation of the Company
               to pay certain expenses to the extent provided for in
               Section 5(l) hereof, (ii) the obligation of the Company to
               pay commissions and hold the Agents harmless as provided in
               Section 9 hereof (and, for purposes of said Section 9, such
               a failure of such condition to be fulfilled shall be
               considered a default by the Company on its obligation to
               deliver such Securities), and (iii) any liability under
               Section 8 hereof.

                    8.   Indemnification.
                         ---------------

                    (a)  The Company will indemnify and hold harmless each
               Agent against any losses, claims, damages or liabilities,
               joint or several, to which such Agent may become subject,
               under the Act or otherwise, insofar as such losses, claims,
               damages or liabilities or actions in respect thereof arise
               out of or are based upon an untrue statement or alleged
               untrue statement of a material fact contained in the
               Registration Statement, any Preliminary Prospectus, the
               Prospectus or the Prospectus as amended or supplemented, or
               arise out of or are based upon the omission or alleged
               omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein
               not misleading, and will reimburse such Agent for any legal
               or other expenses reasonably incurred by it, as incurred, in
               connection with investigating or defending any such loss,
               claim, damage, liability or action; provided, however, that
                                                   --------  -------
               the Company shall not be liable in any such case to the
               extent that any such loss, claim, damage or liability or
               action in respect thereof arises out of or is based upon an
               untrue statement or alleged untrue statement or omission or
               alleged omission made in the Registration Statement, any
               Preliminary Prospectus, the Prospectus or the Prospectus as
               amended or supplemented in reliance upon and in conformity
               with written information furnished to the Company by such
               Agent specifically for use therein; and provided, further,
               that the indemnity agreement contained in this Section 8(a)
               shall not inure to the benefit of any Agent on account of
               any losses, claims, damages or liabilities or actions in
               respect thereof arising solely from the sale of Securities
               by or through such Agent pursuant to a Terms Agreement or
               otherwise to any person if a copy of the Prospectus as then
               amended and supplemented with respect to such Securities
               shall not have been sent or given to such person with or
               prior to written confirmation of the sale involved (assuming
               that the Company shall have previously furnished such
               documents to such Agent in a timely fashion), and if the
               Prospectus (as so amended or supplemented) would have cured
               the defect giving rise to such losses, claims, damages or
               liabilities.

                    (b)  Each Agent will indemnify and hold harmless the
               Company against any losses, claims, damages or liabilities
               to which the Company may become subject, under the Act or
               otherwise, insofar as such losses, claims, damages or
               liabilities or actions in respect thereof arise out of or
               are based upon an untrue statement or alleged untrue
               statement of a material fact contained in the Registration
               Statement, any Preliminary Prospectus, the Prospectus or the
               Prospectus as amended or supplemented, or arise out of or
               are based upon the omission or alleged omission to state
               therein a material fact required to be stated therein or
               necessary to make the statements therein not misleading, in
               each case to the extent, but only to the extent, that such
               untrue statement or alleged untrue statement or omission or
               alleged omission was made in the Registration Statement, any
               Preliminary Prospectus, the Prospectus or the Prospectus as
               amended or supplemented in reliance upon and in conformity
               with written information furnished to the Company by such
               Agent specifically for use therein, and will reimburse the
               Company for any legal or other expenses incurred by the
               Company, as incurred, in connection with investigating or
               defending any such loss, claim, damage or liability or
               action.  Each Agent hereby furnishes to the Company in
               writing expressly for use in the Registration Statement, any
               Preliminary Prospectus, the Prospectus and the Prospectus as
               amended or supplemented (i) the second sentence in the last
               paragraph on the cover page of the Prospectus relating to
               the offerings of Medium-Term Notes by the Agents, as
               principal, (ii) the legend on the inside cover page relating
               to stabilizing transactions by the Agents, and (iii) under
               "Plan of Distribution," the fifth, sixth, seventh and eighth
               sentences in the first paragraph, the third and last
               sentences of the fourth paragraph, the sixth, seventh,
               eighth and ninth paragraphs and the statements relating to
               the Agents in the last paragraph.

                    (c)  Promptly after receipt by an indemnified party
               under Section 8(a) or Section 8(b) of notice of the
               commencement of any action, such indemnified party shall, if
               a claim in respect thereof is to be made against the
               indemnifying party under such Section, notify the
               indemnifying party in writing of the commencement thereof;
               but the omission so to notify the indemnifying party shall
               not relieve it from any liability which it may have to any
               indemnified party otherwise than under such Section.  In
               case any such action shall be brought against any
               indemnified party and it shall notify the indemnifying party
               of the commencement thereof, the indemnifying party shall be
               entitled to participate therein and, to the extent that it
               shall wish, jointly with any other indemnifying party
               similarly notified, to assume the defense thereof, with
               counsel satisfactory to such indemnified party (who shall
               not, except with the consent of the indemnified party, be
               counsel to the indemnifying party); provided, however, in no
                                                   --------  -------
               event shall such indemnifying parties be obligated to retain
               more than one counsel (and necessary local counsel), in
               addition to counsel for such indemnifying parties, to rep-
               resent the indemnified parties, and after notice from the
               indemnifying party to such indemnified party of its election
               so to assume the defense thereof, the indemnifying party
               shall not be liable to such indemnified party under such
               Section for any legal expenses of other counsel or any other
               expenses, in each case subsequently incurred by such
               indemnified party, in connection with the defense thereof
               other than reasonable costs of investigation.  Each
               indemnified party may also participate at its own expense in
               the defense of any such action.  No indemnifying party
               shall, without the prior written consent of the indemnified
               party, effect any settlement of any pending or threatened
               proceeding in respect of which any indemnified party is or
               could have been a party and indemnity could have been sought
               hereunder by such indemnified party, unless such settlement
               includes (i) an unconditional release of such indemnified
               party from all liability on claims that are the subject
               matter of such proceeding and (ii) no statement as to or an
               admission of fault, culpability or failure to act by or on
               behalf of an indemnified party.

                    (d)  If the indemnification provided for in Section
               8(a) or Section 8(b) hereof is unavailable to or
               insufficient to hold harmless an indemnified party in
               respect of any losses, claims, damages or liabilities (or
               actions in respect thereof) referred to therein, then each
               indemnifying party shall contribute to the amount paid or
               payable by such indemnified party as a result of such
               losses, claims, damages or liabilities (or actions in
               respect thereof) in such proportion as is appropriate to
               reflect any relevant equitable considerations including the
               relative fault of the Company on the one hand and each Agent
               on the other in connection with the statements or omissions
               which resulted in such losses, claims, damages or liabili-
               ties (or actions in respect thereof), and relative benefit
               of the Company on the one hand and each Agent on the other. 
               Relative fault shall be determined by reference to, among
               other things, whether the untrue or alleged untrue statement
               of a material fact or the omission or alleged omission to
               state a material fact required to be stated therein or
               necessary in order to make the statements therein not
               misleading relates to information supplied by the Company on
               the one hand or by any Agent on the other and the parties'
               relative intent, knowledge, access to information and oppor-
               tunity to correct or prevent such statement or omission. 
               The relative benefits received by the Company on the one
               hand and each Agent on the other shall be deemed to be in
               the same proportion as the total net proceeds from the sale
               of Securities (before deducting expenses) received by the
               Company bear to the total commissions or discounts received
               by such Agent in respect thereof.  The Company and each
               Agent agree that it would not be just and equitable if
               contribution pursuant to this Section 8(d) were determined
               (i) with respect only to any losses, claims, damages or
               liabilities referred to in Section 8(a) hereof, by per
               capita allocation (even if all Agents were treated as one
               entity for such purpose) or (ii) by any method of allocation
               which does not take account of the equitable considerations
               referred to above in this Section 8(d).  The amount paid or
               payable by an indemnified party as a result of the losses,
               claims, damages or liabilities (or actions in respect
               thereof) referred to above in this Section 8(d) shall be
               deemed to include any legal or other expenses reasonably
               incurred by such indemnified party in connection with
               investigating or defending any such action or claim.  No
               person guilty of fraudulent misrepresentation (within the
               meaning of Section 11(f) of the Act) shall be entitled to
               contribution from any person who was not guilty of such
               fraudulent misrepresentation.  The obligations of each of
               the Agents under this Section 8(d) to contribute are several
               and are not joint.

                    (e)  The obligations of the Company under this Section
               8 shall be in addition to any liability which the Company
               may otherwise have and shall extend, upon the same terms and
               conditions, to each person, if any, who controls any Agent
               within the meaning of the Act.  The obligations of each
               Agent under this Section 8 shall be in addition to any
               liability which such Agent may otherwise have and shall
               extend, upon the same terms and conditions, to each director
               of the Company, to each officer of the Company who has
               signed the Registration Statement and to each person, if
               any, who controls the Company within the meaning of the Act.

                    9.   Nonperformance.  Each Agent, in soliciting offers
                         --------------
          to purchase Securities from the Company and in performing the
          other obligations of such Agent hereunder (other than in respect
          of any purchase by an Agent as principal pursuant to a Terms
          Agreement or otherwise), is acting solely as agent for the
          Company and not as principal.  Each Agent will make reasonable
          efforts to assist the Company in obtaining performance by each
          purchaser whose offer to purchase Securities from the Company was
          solicited by such Agent and has been accepted by the Company, but
          such Agent shall not have any liability to the Company in the
          event such purchase is not consummated for any reason.  If the
          Company shall default on its obligation to deliver Securities to
          a purchaser whose offer it has accepted, the Company shall (i)
          hold each Agent harmless against any loss, claim or damage
          arising from or as a result of such default by the Company and
          (ii) notwithstanding such default, pay to the Agent that
          solicited such offer any commission to which it would be entitled
          in connection with such sale.

                    10.  Survival of Agreement.  The respective indem
                         ---------------------
          nities, agreements, representations, warranties and other
          statements by any Agent and the Company set forth in or made
          pursuant to this Agreement shall remain in full force and effect
          regardless of any investigation (or any statement as to the
          results thereof) made by or on behalf of any Agent or any
          controlling person of any Agent or the Company, or any officer or
          director or any controlling person of the Company, and shall
          survive each delivery of and payment for any of the Securities.

                    11.  Suspension or Termination.  The provisions of this
                         -------------------------
          Agreement relating to the solicitation of offers to purchase
          Securities from the Company may be suspended or terminated at any
          time by the Company as to any Agent or by any Agent as to such
          Agent upon the giving of written notice of such suspension or
          termination to such Agent or the Company, as the case may be.  In
          the event of such suspension or termination with respect to any
          Agent, this Agreement shall remain in full force and effect with
          respect to (i) any Agent as to which such suspension or termi-
          nation has not occurred, (ii) the rights and obligations of any
          party which have previously accrued or which relate to Securities
          which are already issued, agreed to be issued or the subject of a
          pending offer at the time of such suspension or termination,
          (iii) Sections 2(e), 5(d), 5(e), 5(l), 8, 9 and 10 hereof, and
          (iv) the obligations of the Company to amend or supplement the
          Prospectus, so long as any Agent continues to hold Securities as
          principal.

                                                                    ANNEX I

                           Northwest Natural Gas Company

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

                    This Administrative Procedure relates to the Securities
          defined in the Distribution Agreement, dated  . , 1998 (the
          "Distribution Agreement"), amongst Northwest Natural Gas Company
          (the "Company"), on the one hand, and Merrill Lynch & Co.,
          Merrill Lynch, Pierce, Fenner & Smith Incorporated, PaineWebber
          Incorporated, and each other person which shall become a party
          thereto (each, an "Agent" and, together, the "Agents"), on the
          other.  Defined terms used herein and not defined herein shall
          have the meanings given such terms in the Distribution Agreement
          or the Indentures.  An Agent, in relation to a purchase of a
          Security by a purchaser solicited by such Agent, is referred to
          herein as the "Selling Agent" and, in relation to a purchase of a
          Security by such Agent as principal other than pursuant to a
          Terms Agreement, as the "Purchasing Agent".  As used herein, the
          term "business day" shall mean any day when banks in New York
          City are not authorized or obligated by law or executive order to
          remain closed.

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

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

                    The order dated July 10, 1998 of the Public Utility
          Commission of Oregon (the "OPUC") authorizes the issuance and
          sale of the Securities, provided that the Company report at least
          two bid quotes for each Security issued and that the Company's
          senior debt securities maintain investment grade bond ratings
          from at least two nationally recognized statistical rating
          organizations.  The order dated June 25, 1998 of the Washington
          Utilities and Transportation Commission (the "WUTC") establishes
          compliance with applicable statutory provisions with respect to
          the issuance and sale of the Securities.  In addition, such order
          of the OPUC authorizes, and such order of the WUTC establishes
          compliance with applicable statutory provisions with respect to,
          the issuance and sale by the Company (i) only of Securities
          bearing interest at fixed rates, established within the maximum
          all-in spreads over Benchmark Treasury Yields for various
          maturities (determined in accordance with said orders as of the
          time the commitment to purchase any Securities is received by the
          Company and the Agent) and (ii) of Securities to Agents, as
          principal, at 100% of the principal amount thereof less a
          percentage not to exceed the commission applicable to an agency
          sale of Securities of the same maturity.

                    As stated in the Company's Prospectus dated  . , 1998,
          if the terms of any Security, as determined by the Company,
          provide that such Security will be redeemable at the option of
          the company, such Security will be made redeemable in whole or in
          part. 

          Procedure for Rate Changes:
          --------------------------

                    When a decision has been reached to change the interest
          rate on or other variable terms with respect to any Securities
          being offered for sale, the Company will promptly advise the
          Agents and the Agents will forthwith suspend solicitation of
          offers to purchase such Securities.  The Agent will telephone the
          Company with recommendations as to the changed interest rates or
          other variable terms.  At such time as the Company advises the
          Agents of the new interest rates or other variable terms, the
          Agent may resume solicitation of offers to purchase such
          Securities.  Until such time only "indications of interest" may
          be recorded.

          Acceptance or Rejection of Offers by Company:
          --------------------------------------------

                    Each Agent will promptly advise the Company by
          telephone or other appropriate means of all reasonable offers to
          purchase Securities, other than those rejected by such Agent. 
          Each Agent, in its discretion reasonably exercised, may reject
          any offer received by it, in whole or in part.  Each Agent also
          may make offers to the Company to purchase Securities as a
          Purchasing Agent.  The Company, in its sole discretion, may
          accept any offer to purchase Securities and may reject any such
          offer, in whole or in part.

                    The Company will promptly notify the Selling Agent or
          Purchasing Agent, as the case may be, of its acceptance or
          rejection of an offer to purchase Securities.  If the Company
          accepts an offer to purchase Securities, it will confirm such
          acceptance in writing to the Selling Agent or Purchasing Agent,
          as the case may be. 

                    As mentioned above, the order dated July 10, 1998 of
          the OPUC requires that, for each issuance of Securities, the
          Company seek and report to the OPUC at least one other bid quote
          in addition to the bid that is accepted.

          Settlement:
          ----------

                    The receipt of immediately available funds by the
          Company in payment for a Security and the authentication and
          delivery of such Security will, with respect to such Security,
          constitute "Settlement."

                    All offers solicited by a Selling Agent or made by a
          Purchasing Agent and accepted by the Company will be settled on a
          date (the "Settlement Date") which shall be the third business
          day after the date of acceptance of such offer, unless the
          Company and the purchaser shall agree to settle (a) on any other
          business day after the acceptance of such offer or (b) with
          respect to an offer accepted by the Company prior to 10:00 a.m.,
          New York City time, on the date of such acceptance.

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

                    Subject to its representations, warranties and
          covenants contained in the Distribution Agreement, the Company
          may instruct the Agents to suspend solicitation of purchases at
          any time.  Upon receipt of such instructions, the Agents will
          forthwith suspend solicitation of offers to purchase from the
          Company until such time as the Company has advised them that
          solicitation of offers to purchase may be resumed.  If the
          Company decides to amend or supplement the Prospectus (other than
          to change interest rates or other variable terms with respect to
          the offering of the Securities), it will promptly advise the
          Agents and will furnish the Agents and their counsel with copies
          of the proposed amendment or supplement.

                    In the event that at the time the solicitation of
          offers to purchase from the Company is suspended (other than to
          change interest rates or other variable terms) there shall be any
          orders outstanding which have not been settled, the Company will
          promptly advise the Agents and the Trustee whether such orders
          may be settled and whether copies of the Prospectus as
          theretofore amended and/or supplemented as in effect at the time
          of the suspension may be delivered in connection with the
          settlement of such orders.  The Company will have the sole
          responsibility for such decision and for any arrangements which
          may be made in the event that the Company determines that such
          orders may not be settled or that copies of such Prospectus may
          not be so delivered.


          Delivery of Confirmation and Prospectus to
          Purchaser by Selling Agent:
          ------------------------------------------

                    The Selling Agent will deliver to the purchaser of a
          Security a written confirmation of the sale and delivery and
          Payment instructions.  In addition, the Selling Agent will
          deliver to such purchaser or its agent the Prospectus as amended
          or supplemented (including the Pricing Supplement) relating to
          such Security prior to delivery to such purchaser or its agent
          of, or together with, the earlier to be delivered of (a) the
          confirmation of sale or (b) the Security.


          Instruction from Company to Trustee
          for Preparation of Securities:
          -----------------------------------

                    After receiving the Sale Information from the Selling
          Agent or Purchasing Agent, as the case may be, the Company will
          communicate such Sale Information to the Mortgage Trustee or the
          Indenture Trustee, as the case may be, by telephone (confirmed in
          writing, by facsimile transmission or by other acceptable written
          means).

                    The Company will instruct such Trustee by telephone
          (confirmed in writing, by facsimile transmission or by other
          acceptable written means) to authenticate and deliver the
          Securities no later than 2:15 p.m., New York City time, on the
          Settlement Date.  Such instruction will be given by the Company
          prior to 3:00 p.m., New York City time, on the business day prior
          to the Settlement Date, unless the Settlement Date is the date of
          acceptance by the Company of the offer to purchase Securities, in
          which case such instruction will be given by the Company to the
          Trustee by 10:00 a.m., New York City time, on the Settlement
          Date.

          Procedures for Book-Entry Securities:
          ------------------------------------

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

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

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

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

          ---------------------------------------

                    The Company will instruct the Mortgage Trustee or the

                         that will serve as the documentary control of the

                         York City time, on the Settlement Date, deliver

                         Settlement Date, such Selling Agent will deliver
                         payment for such Securities in immediately

                         reserves the right to withhold payment for which
                         it shall not have received funds from the
                         purchaser.)

                         immediately available funds to the Company's

                    Securities which reset daily or weekly, the date five
                    calendar days preceding the Interest Payment Date) and,
                    if then calculable, the amount of interest payable on
                    such Interest Payment Date (which amount shall have
                    been confirmed by the Trustee).

               (5)  CUSIP number of the Book-Entry Security representing
                    such Security.

               (6)  Whether such Book-Entry Security represents any other
                    Securities issued or to be issued in book-entry form.

               C.   The Company will complete and deliver to the Trustee a
          Book-Entry Security representing such Security in a form that has
          been approved by the Company, the Agents and the Trustee. 

               D.   The Trustee will authenticate the Book-Entry Security
          representing such Security.

               E.   DTC will credit such Security to the participant
          account of the Trustee maintained by DTC.

               F.   The Trustee will enter a Same-Day Funds Settlement
          System ("SDFS") deliver order through DTC's Participant Terminal
          System instructing DTC (i) to debit such Security to the
          Trustee's participant account and credit such Security to the
          participant account, maintained by DTC, of the Agent which
          presented to the Company the offer to purchase such Security
          which was accepted by the Company (the "Presenting Agent") and
          (ii) to debit the settlement account of the Presenting Agent and
          credit the settlement account of the Trustee maintained by DTC,
          in an amount equal to the price of such Security less such
          Agent's commission.

               G.   The Presenting Agent will enter an SDFS deliver order
          through DTC's Participant Terminal System instructing DTC (i) to
          debit such Security to the Presenting Agent's participant account
          and credit such Security to the participant account of the
          Participants maintained by DTC and (ii) to debit the settlement
          accounts of such Participants and credit the settlement account
          of the Presenting Agent maintained by DTC, in an amount equal to
          the initial public offering price of such Security.

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

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

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

               K.   The Agent will confirm the purchase of such Security to
          the purchaser either by transmitting to the Participant with
          respect to such Security a confirmation order through DTC's
          Participant Terminal System or by mailing a written confirmation
          to such purchaser.

               L.   Settlement Procedures Timetable:

                    (1)  For orders of Securities accepted by the Company,
                         Settlement Procedures A through K shall be
                         completed as soon as possible but not later than
                         the respective times (New York City time) set
                         forth below:

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

                            A           11:00 a.m. on the trade date
                            B           2:00 p.m. on the trade date
                            C           3:00 p.m. on the Business
                                        Day before Settlement Date
                            D           9:00 a.m. on Settlement Date
                            E           10:00 a.m. on Settlement Date
                            F-G         No later than 2:00 p.m. on

                            H           4:45 p.m. on Settlement Date
                            I-K         5:00 p.m. on Settlement Date

               (2)  If a sale is to be settled more than one Business Day
                    after trade date, Settlement Procedures A and B may, if
                    necessary, be completed at any time prior to the
                    specified times on the first Business Day after such
                    trade date.  In connection with a sale which is to be
                    settled more than one Business Day after the trade
                    date, if the initial interest rate for a Floating Rate
                    Security is not known at the time that the Sale
                    Information is given by the Presenting Agent to the
                    Company, Settlement Procedures A and B shall be
                    completed as soon as such rates have been determined,
                    but no later than 11:00 a.m. and 2:00 p.m., New York
                    City time, respectively, on the second Business Day
                    before the Settlement Date.   Settlement Procedure H is
                    subject to extension in accordance with any extension
                    of Fedwire closing deadlines and in the other events
                    specified in the SDFS operating procedures in effect on
                    the Settlement Date.

               (3)  If settlement of a Security issued in book-entry form
                    is rescheduled or canceled, the Trustee will deliver to
                    DTC, through DTC's Participant Terminal System, a
                    cancellation message to such effect by no later than
                    2:00 p.m., New York City time, on the Business Day
                    immediately preceding the scheduled Settlement Date.

          Failure of Purchaser to Pay Selling Agent:
          -----------------------------------------

                               Certificated Securities
                               -----------------------

                    If a purchaser shall fail to make payment to the
          Selling Agent for any Security, the net proceeds to the Company
          which, theretofore, shall have been paid by the Selling Agent to
          the Company, the Selling Agent will promptly notify the Mortgage
          Trustee or the Indenture Trustee, as the case may be, and the
          Company of such failure by telephone, promptly confirmed in
          writing or by facsimile transmission or by other acceptable
          written means.  The Selling Agent promptly will return such
          Security to such Trustee.  Promptly upon receipt of such Security
          by such Trustee, the Company will return to the Selling Agent an
          amount equal to the amount previously paid to the Company in
          respect of such Security.  Such Trustee will cancel any Security
          in respect of which such a failure shall occur, make appropriate
          entries in its records and, unless otherwise instructed by the
          Company, destroy such Security.

                                Book-Entry Securities
                                ---------------------

                    If the Trustee fails to enter an SDFS deliver order
          with respect to a Book-Entry Security issued in book-entry form
          pursuant to paragraph F above, the Trustee may deliver to DTC,
          through DTC's Participant Terminal System, as soon as practicable
          a withdrawal message instructing DTC to debit such Security to
          the participant account of the Trustee maintained at DTC. DTC
          will process the withdrawal message, provided that such
          participant account contains a principal amount of the Book-Entry
          Security representing such Security that is at least equal to the
          principal amount to be debited.  If withdrawal messages are
          processed with respect to all the Securities represented by a
          Book-Entry Security, the Trustee will mark such Book-Entry
          Security "canceled", make appropriate entries in its records and
          send such canceled Book-Entry Security to the Company.  The CUSIP
          number assigned to such Book-Entry Security shall, in accordance
          with CUSIP Service Bureau procedures, be canceled and not
          immediately reassigned.  If withdrawal messages are processed
          with respect to a portion of the Securities represented by a
          Book-Entry Security, the Trustee will exchange such Book-Entry
          Security for two Book-Entry Securities, one of which shall
          represent the Book-Entry Securities for which withdrawal messages
          are processed and shall be canceled immediately after issuance,
          and the other of which shall represent the other Securities
          previously represented by the surrendered Book-Entry Security and
          shall bear the CUSIP number of the surrendered Book-Entry
          Security.

                    If the purchase price for any Book-Entry Security is
          not timely paid to the Participants with respect to such Security
          by the beneficial purchaser thereof (or a person, including an
          indirect participant in DTC acting on behalf of such purchaser),
          such Participants and, in turn, the related Agent may enter SDFS
          deliver orders through DTC's Participant Terminal System
          reversing the orders entered pursuant to paragraphs F and G
          above, respectively. Thereafter, the Trustee will deliver the
          withdrawal message and take the related actions described in the
          preceding paragraph.  If such failure shall have occurred for any
          reason other than default by the applicable Agent to perform its
          obligations hereunder or under the Distribution Agreement, the
          Company will reimburse such Agent on an equitable basis for its
          loss of the use of funds during the period when the funds were
          credited to the account of the Company.

                    Notwithstanding the foregoing, upon any failure to
          settle with respect to a Book-Entry Security, DTC may take any
          actions in accordance with its SDFS operating procedures then in
          effect.  In the event of a failure to settle with respect to a
          Security that was to have been represented by a Book-Entry
          Security also representing other Securities, the Trustee will
          provide, in accordance with paragraphs C and D above, for the
          authentication and issuance of a Book-Entry Security representing
          such remaining Securities and will make appropriate entries in
          its records.

          Dear Sirs:

                    With reference to the issuance and sale from
          time-to-time by Northwest Natural Gas Company (the "Company"),
          pursuant to the Distribution Agreement, dated  . , 1998 (the
          "Agreement"), between the Company and each of you, of not to
          exceed $143,000,000 in aggregate principal amount of (i) the
          Company's First Mortgage Bonds, designated Secured Medium-Term
          Notes, Series B (the "Secured Notes") to be issued under the

          to Bankers Trust Company (the "Corporate Trustee") and R.G. Page
          (Stanley Burg, successor), as trustees, as supplemented by twenty

          the Company's Unsecured Medium-Term Notes, Series B  (the
          "Unsecured Notes"), to be issued under the Company's Indenture,
          dated as of June 1, 1991 (the "Indenture"), to Bankers Trust
          Company, as trustee (the "Indenture Trustee") (the Secured Notes
          and the Unsecured Notes being hereinafter collectively referred
          to as the "Notes"), and the appointment of each of you as agents
          of the Company pursuant to the Agreement for the purposes  of
          soliciting and receiving offers to purchase Notes, as agents, and
          purchasing Notes, as principals, from the Company, please be
          advised that, as General Counsel of the Company, I have
          participated in the preparation of or reviewed (a) the Restated
          Articles of Incorporation, as amended, and Bylaws, as amended, of
          the Company; (b) the Mortgage; (c) the Indenture; (d) the
          Agreement; (e) the registration statement (File No. 333-15323)
          (the "Initial Registration Statement"), filed by the Company with
          the Securities and Exchange Commission (the "SEC") for the
          registration under the Securities Act of 1933, as amended (the
          "1933 Act"), of $150,000,000 of the Notes, of which $43,000,000
          remain unsold, and for the qualification under the Trust
          Indenture Act of 1939, as amended (the "Trust Indenture Act"), of
          the Mortgage and the Indenture, which Initial Registration
          Statement became effective on April 24, 1997; (f) the
          registration statement (File No. 333- . ) (the "Subsequent
          Registration Statement"), filed by the Company with the SEC for
          the registration under the 1933 Act of an additional $100,000,000
          of the Notes, and for the qualification under the Trust Indenture
          Act of the Mortgage and the Indenture, which Subsequent
          Registration Statement became effective on  . , 1998; (g) the
          combined prospectus relating to the Notes constituting a part of
          the Subsequent Registration Statement in the form in which the
          Subsequent Registration Statement became effective, or if such
          combined prospectus has been amended or supplemented subsequent
          to such effectiveness, as so amended and supplemented, including
          the documents incorporated therein by reference pursuant to Item
          12 of Form S-3 (the "Prospectus"); (h) the proceedings before the
          Public Utility Commission of Oregon (the "OPUC") and the
          Washington Utilities and Transportation Commission (the "WUTC")
          relating to the issuance and sale of the Notes; and (i) the
          records of various corporate and other proceedings relating to
          the authorization, issuance and sale of the Notes.  I have also
          examined such other documents and satisfied myself as to such
          other matters as I have deemed necessary in order to render this
          opinion.  I have not examined the Notes, except specimens
          thereof.

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

                    I am of the opinion that:

                    (1)  The Company is a validly organized and existing
               corporation in good standing under the laws of the State of
               Oregon, is authorized to transact business in the State of
               Washington, and has power (corporate and other) to own its
               properties and conduct its business as described in  the
               Prospectus.

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

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

                    (4)  The Mortgage and the Indenture have been duly and
               validly authorized by all necessary corporate action, have
               been duly and validly executed and delivered, and are valid
               and binding instruments enforceable in accordance with their
               terms, subject, as to enforcement, to laws and principles of
               equity relating to or affecting generally the enforcement of
               creditors rights, including, without limitation, bankruptcy
               and insolvency.

                    (5)  The Mortgage constitutes a first security interest
               on all of the personal properties and fixtures owned by the
               Company that are described in the Mortgage and are intended
               to be subject to the lien thereof, subject only to Excepted
               Encumbrances (as defined in the Mortgage); and the
               description in the Mortgage of such properties and fixtures
               is adequate to constitute the Mortgage a security
               interest thereon.

                    (6)  The Company has good and sufficient title to all
               of the real properties owned by the Company that are
               described in the Mortgage and intended to be subject to the
               lien thereof, subject only to Excepted Encumbrances (as
               defended in the Mortgage) and to minor defects and
               irregularities of the nature customarily found in properties
               of like size and character; the description in the Mortgage
               of such properties is adequate to constitute the Mortgage a
               lien thereon; and the Mortgage is a valid first mortgage
               lien on such properties, subject to the exceptions noted
               above in this paragraph (6).

                    (7)  The form of the Secured Notes has been duly
               authorized and has been established in conformity with the
               provisions of the Mortgage; the form of the Unsecured Notes
               bearing interest at a fixed rate, has been duly authorized
               and has been established in conformity with the provisions
               of the Indenture; and the form of the Unsecured Notes,
               bearing interest at a variable rate or not bearing interest,
               when set forth in a Company Order or Orders (as defined in
               the Indenture) or established by procedures acceptable to
               the Indenture Trustee specified in a Company Order or
               Orders, will have been duly authorized and will have been
               established in conformity with the provisions of the
               Indenture.

                    (8)  The Secured Notes have been duly authorized by the
               resolutions adopted by the Board of Directors on May 27,
               1993, September 26, 1996, April 24, 1997 and February 26,
               1998 (the "Board Resolutions"), and when the terms of the
               Secured Notes shall have been determined as contemplated by
               and in accordance with the Mortgage, the Board Resolutions
               and written orders or instructions evidencing determinations
               by officers of the Company, such terms will have been duly
               authorized by the Company and will have been established in
               conformity with the terms of the Mortgage.

                    (9)  The Unsecured Notes have been duly authorized by
               the Board Resolutions, and when the terms of the Unsecured
               Notes shall have been determined as contemplated by and in
               accordance with the Indenture, the Board Resolutions and, to
               the extent required by the Indenture and the Board
               Resolutions, by Officers' Certificates (as defined in the
               Indenture), Company Orders and procedures acceptable to the
               Indenture Trustee specified in such Company Orders, such
               terms will have been duly authorized by the Company and will
               have been established in conformity with the terms of the
               Indenture.

                    (10) The Notes, when (a) executed by the Company, (b)
               completed, authenticated and delivered by the Corporate
               Trustee or the Indenture Trustee, as the case may be, (c)
               issued and delivered by the Company and (d) paid for, all as
               contemplated by and in accordance with the Mortgage, in the
               case of Secured Notes, the Indenture, in the case of
               Unsecured Notes, the Board Resolutions, and (to the extent
               required by the Mortgage or the Indenture and the Board
               Resolutions) Officers' Certificates, Company Orders,
               procedures acceptable to the Indenture Trustee specified in
               such Company Orders, written orders or instructions
               evidencing determinations by the officers of the Company,
               the Agreement, the Administrative Procedure (as defined in
               the Agreement), and Terms Agreements (as defined in the
               Agreement), if any, will be duly issued under the Mortgage
               or the Indenture, as the case may be, and will constitute
               valid and legally binding obligations of the Company,
               entitled to the benefits provided by the Mortgage or the
               Indenture, as the case may be, and enforceable in accordance
               with their terms, subject, as to enforcement, to laws and
               principles of equity relating to or affecting generally the
               enforcement of creditors' rights, including, without
               limitation, bankruptcy and insolvency, and, in the case of
               the Secured Notes, entitled to the benefit of the security
               afforded by the Mortgage.

                    (11) The issuance and sale of the Notes, the compliance
               by the Company with all of the provisions of the Notes, the
               Mortgage, the Indenture and the Agreement and the
               consummation of the transactions contemplated by the
               Agreement will not result in a breach or violation of any of
               the terms and provisions of, or constitute a default under,
               any statute, any indenture, mortgage, deed of trust or other
               agreement or instrument known to me to which the Company is
               a party or by which it is bound or to which any of the
               property of the Company is subject, the Company's Restated
               Articles of Incorporation, as amended, or Bylaws, as
               amended, or any order, rule or regulation known to me of any
               court or  governmental agency or body having jurisdiction
               over the Company or any of its properties.

                    (12) The OPUC has issued orders authorizing, and the
               WUTC has issued orders establishing compliance with
               applicable statutory provisions with respect to, the
               issuance and sale by the Company of the Notes; and no
               further approval, authorization, consent or other order of
               any public board or body (other than in connection or in
               compliance with the provisions of the securities or blue sky
               laws of any jurisdiction) is legally required for the
               issuance and sale of the Notes on the terms and conditions
               set forth in the Agreement.

                    (13) The statements of Oregon and Federal law (other
               than the 1933 Act, the Securities Exchange Act of 1934 and
               the Trust Indenture Act), and legal conclusions based
               thereon, contained in, or in the documents incorporated by
               reference in, the Prospectus have been reviewed by me and
               are correct (except to the extent that any statement
               contained in a document incorporated or deemed to be
               incorporated by reference in the Prospectus may be deemed to
               be modified or superseded in the Prospectus or in any other
               subsequently filed document which also is or is deemed to be
               incorporated by reference in the Prospectus).

                    (14) Except as described in the Prospectus, there are
               no pending material legal or governmental proceedings and,
               to my knowledge, no material threatened legal or
               governmental proceedings, to which the Company is a party or
               of which any of the property of the Company is subject,
               other than ordinary routine litigation incidental to the
               kind of business conducted by the Company.

                    In the course of the preparation by the Company of the
          Initial and the Subsequent Registration Statements and the
          Prospectus, I had conferences with certain officers and employees
          of the Company, but I have made no independent verification of
          the accuracy or completeness of the representations and
          statements made to me by such person or the information included
          by the Company in either of such Registration Statements and the
          Prospectus, and take no responsibility therefor, except as forth
          in paragraph 12 hereof.  However, my examination of such
          Registration Statements and the Prospectus and my discussions in
          the above-mentioned conferences did not disclose to me any
          information which gives me reason to believe that, when each of
          the Initial and Subsequent Registration Statements became
          effective, it contained an untrue statement of a material fact or
          omitted to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading, or that,
          as of the date of this opinion, the Prospectus includes an untrue
          statement of a material fact or omits to state a material fact
          necessary in order to make the statements therein, in the light
          of the circumstances under which they were made, not misleading;
          provided, that I do not express any belief as to the financial
          statements or other financial or statistical data contained in
          such Registration Statements or the Prospectus, or as to the
          Forms T-1 or T-2, or as to any information contained therein
          furnished to the Company in writing by any of you expressly for
          use therein.

                    This opinion is limited to the facts and law at the
          date hereof.  In rendering the opinions set forth in paragraphs
          10, 11 and 12 above, I have necessarily assumed that, at the time
          of any issuance, sale and delivery of a Note (i) the Board of
          Directors of the Company (or any committee thereof acting
          pursuant to authority properly delegated to such committee by the
          Board of Directors) has not taken any action to rescind or
          otherwise reduce its prior authorization of the issuance of the
          Notes and an officer of the Company, as stated in the resolutions
          of the Board of Directors (or any such committee) relating to the
          Notes, has executed and delivered such Notes, (ii) the orders of
          the OPUC and the WUTC with respect to the Notes remain in full
          force and effect and have not been modified or amended by the
          OPUC or the WUTC, respectively, and the Company complies with the
          terms of such orders and (iii) the orders of the SEC with respect
          to the Initial Registration Statement, the Subsequent
          Registration Statement, the Mortgage and the Indenture remain in
          full force and effect and have not been modified or amended by
          the SEC.

                    I am a member of the bar of the State of Oregon and do
          not hold myself out as an expert on the laws of the State of
          Washington, the State of New York or Federal securities laws.
          Accordingly, in rendering this opinion, I have relied, with your
          consent, as to certain matters of Washington law, upon the
          opinion of even date herewith addressed to you by Stoel Rives
          LLP, special Washington counsel to the Company, and, as to all
          matters governed by the laws of the State of New York, the 1933
          Act, the Securities Exchange Act of 1934 and the Trust Indenture
          Act, upon the opinion of even date herewith addressed to you by
          Thelen Reid & Priest LLP, New York, New York, counsel for the
          Company.  In rendering this opinion, I have made such reviews of
          the laws of the State of Washington as I believe to be necessary
          to satisfy myself as to questions of Washington law which are not
          addressed by the opinion of Stoel Rives LLP.

                    You, the Trustees and, as to matters governed by the
          laws of the State of Oregon, Thelen Reid & Priest LLP and your
          counsel may rely upon this opinion in connection with the
          issuance and sale of the Notes. Neither you nor any of them may
          rely upon this opinion for any other purpose, and no other person
          may rely upon this opinion for any purpose without, in each case,

          Dear Sirs:

                    With reference to the issuance and sale from time--

          the Company's Unsecured Medium-Term Notes, Series B (the
          "Unsecured Notes"), to be issued under the Company's Indenture,
          dated as of June 1, 1991 (the "Indenture"), to Bankers Trust
          Company, as trustee (the "Indenture Trustee") (the Secured Notes
          and the Unsecured Notes being hereinafter collectively referred
          to as the "Notes"), and the appointment of each of you as agents
          of the Company pursuant to the Agreement for the purposes of 
          soliciting and receiving offers to purchase Notes, as agents, and
          purchasing Notes, as principals, from the Company, please be
          advised that, as counsel to the Company, we have participated in
          the preparation of or reviewed (a) the Restated Articles of
          Incorporation, as amended, and Bylaws, as amended, of the
          Company; (b) the Mortgage; (c) the Indenture; (d) the Agreement;
          (e) the registration statement (File No. 333-15323) (the "Initial
          Registration Statement"), filed by the Company with the
          Securities and Exchange Commission (the "SEC") for the
          registration under the Securities Act of 1933, as amended (the
          "1933 Act"), of $150,000,000 of the Notes, of which $43,000,000
          remain unsold, and for the qualification under the Trust
          Indenture Act of 1939, as amended (the "Trust Indenture Act"), of

          Statement became effective on April 24, 1997; (f) the
          registration statement (File No. 333- . ) (the "Subsequent
          Registration Statement"), filed by the Company with the SEC for

          of the Notes, and for the qualification under the Trust Indenture
          Act of the Mortgage and the Indenture, which Subsequent
          Registration Statement became effective on  . , 1998; (g) the
          combined prospectus relating to the Notes constituting a part of
          the Subsequent Registration Statement in the form in which it
          became effective, or if such combined prospectus has been amended
          or supplemented subsequent to such effectiveness, as so amended
          or supplemented, including the documents incorporated therein by
          reference pursuant to Item 12 of Form S-3 (the "Prospectus"); (h)
          the records of the proceedings before the Public Utility
          Commission of Oregon (the "OPUC") and the Washington Utilities
          and Transportation Commission (the "WUTC") relating to the
          issuance and sale of the Notes; and (i) the records of various
          corporate and other proceedings relating to the authorization,
          issuance and sale of the Notes.  We have also examined such other
          documents and satisfied ourselves as to such other matters as we
          have deemed necessary in order to render this opinion.  We have
          not examined the Notes, except specimens thereof.  

                    In the preparation of this opinion, we have examined
          originals or photostatic or certified copies of such
          certificates, agreements, documents and other papers, and have
          made such inquiries and investigations of law, as we deemed
          appropriate and necessary for the opinion hereinafter set forth. 
          In our examination, we have assumed the authenticity of all
          documents submitted to us as originals, the conformity to
          original documents of all documents submitted to us as certified
          or photostatic copies and the authenticity of the originals of
          such latter documents.  As to certain matters of fact material to
          the opinion expressed herein, we have relied upon certificates of
          various corporate officers of the Company and public officials. 
          We assume the accuracy of the material and factual matters
          contained therein. 

                    We are of the opinion that: 

                    1.   The Company is a validly organized and existing
          corporation in good standing under the laws of the State Of
          Oregon, and is authorized to transact business in the State of
          Washington. 

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

                    3.   The Mortgage and the Indenture have been duly and
          validly authorized by all necessary corporate action, have been
          duly and validly executed and delivered, have been duly qualified
          under the Trust Indenture Act, and are valid and binding
          instruments enforceable in accordance with their terms, subject,
          as to enforcement, to laws and principles of equity relating to
          or affecting generally the enforcement of creditors' rights,
          including, without limitation, bankruptcy and insolvency.

                    4.   The form of the Secured Notes has been duly
          authorized and has been established in conformity with the
          provisions of the Mortgage and conforms to the description
          thereof contained in the Prospectus; the form of the Unsecured
          Notes, bearing interest at a fixed rate, has been duly authorized
          and has been established in conformity with the provisions of the
          Indenture and conforms to the description thereof contained in
          the Prospectus; and the form of the Unsecured Notes, bearing
          interest at a variable rate or not bearing interest, when set
          forth in a Company Order or Orders (as defined in the Indenture)
          or established by procedures acceptable to the Indenture Trustee
          specified in a Company Order or Orders, will have been duly
          authorized and will have been established in conformity with the
          provisions of the Indenture.

                    5.   The Secured Notes have been duly authorized by the
          resolutions adopted by the Board of Directors on May 27, 1993,
          September 26, 1996, April 24, 1997 and February 26, 1998 (the
          "Board Resolutions"), and when the terms of the Secured Notes
          shall have been determined as contemplated by and in accordance
          with the Mortgage, the Board Resolutions and written orders or
          instructions evidencing determinations by Officers of the
          Company, such terms will have been duly authorized by the Company
          and will have been established in conformity with the terms of
          the Mortgage.

                    6.   The Unsecured Notes have been duly authorized by
          the Board Resolutions, and when the terms of the Unsecured Notes
          shall have been determined as contemplated by and in accordance
          with the Indenture, the Board Resolutions and, to the extent
          required by the Indenture and the Board Resolutions, by Officers'
          Certificates (each, as defined in the Indenture), Company Orders
          and procedures acceptable to the Indenture Trustee specified in
          such Company Orders, such terms will have been duly authorized by
          the Company and will have been established in conformity with the
          terms of the Indenture. 

                    7.   The Notes, when (a) executed by the Company, (b)
          completed, authenticated and delivered by the Corporate Trustee
          or the Indenture Trustee, as the case may be, (c) issued and
          delivered by the Company and (d) paid for, all as contemplated by
          and in accordance with the Mortgage, in the case of the Secured
          Notes, the Indenture, in the case of Unsecured Notes, the Board
          Resolutions, and (to the extent required by the Mortgage or the
          Indenture and the Board Resolutions) Officers' Certificates,
          Company Orders, procedures acceptable to the Indenture Trustee
          specified in such Company Orders, written orders or instructions
          evidencing determinations by the officers of the Company, the
          Agreement, the Administrative Procedure (as defined in the
          Agreement) and Terms Agreements (as defined in the Agreement), if
          any, will be duly issued under the Mortgage or the Indenture, as
          the case may be, and will constitute valid and legally binding
          obligations of the Company, entitled to the benefits provided by
          the Mortgage or the Indenture, as the case may be, and
          enforceable in accordance with their terms, subject, as to
          enforcement, to laws and principles of equity relating to or
          affecting generally the enforcement of creditors' rights,
          including, without limitation, bankruptcy and insolvency, and, in
          the case of the Secured Notes, entitled to the benefit of the
          security afforded by the Mortgage.

                    8.   The issuance and sale of the Notes, the compliance
          by the Company with all of the provisions of the Notes, the
          Mortgage, the Indenture and the Agreement and the consummation of
          the transactions contemplated by the Agreement will not result in
          a breach or violation of any of the terms and provisions of,  or
          constitute a default under, the Mortgage and the Indenture or the
          Company's Restated Articles of Incorporation, as amended, or
          Bylaws, as amended.

                    9.   The OPUC has issued orders authorizing, and the
          WUTC has issued orders establishing compliance with applicable
          statutory provisions with respect to, the issuance and sale by
          the Company of the Notes; and no further approval, authorization,
          consent or other order of any public board or body (other than in
          connection or in compliance with the provisions of the securities
          or blue sky laws of any jurisdiction) is legally required for the
          issuance and sale of the Notes through each of you, as agent, on
          the terms and conditions set forth in the Agreement. 

                    10.  Both the Initial and Subsequent Registration
          Statements have become effective under the 1933 Act, and, to the
          best of our knowledge, no stop order suspending the effectiveness
          thereof has been issued and no proceedings for that purpose are
          pending before or have been proposed by the SEC; the Mortgage and
          the Indenture have been duly qualified under the Trust Indenture
          Act; each of the Initial and Subsequent Registration Statements
          at the time it became effective complied, and the Prospectus
          (excluding the documents incorporated therein by reference) as of
          the date of this opinion complies, as to form, in all material
          respects with the requirements of the 1933 Act, the Trust
          Indenture Act (except with respect to the Forms T-1 and Form T-2,
          upon which we do not pass) and the rules and regulations of the
          SEC thereunder; and the documents incorporated by reference in
          the Prospectus pursuant to Item 12 of Form S-3 (other than the
          financial statements and other financial or statistical data
          contained therein, upon which we express no opinion), as of their
          respective dates of filing, complied as to form in all material
          respects with the requirements of the Securities Exchange Act of
          1934, as amended (the "Exchange Act"), and the rules and
          regulations of the SEC thereunder.

                    In the course of the preparation by the Company of the
          Initial and the Subsequent Registration Statements and the
          Prospectus, we had conferences with certain officers and
          employees of the Company, with the General Counsel for the
          Company and with you and your counsel, but we made no independent
          verification of the accuracy or completeness of the
          representations and statements made to us by such persons or the
          information included by the Company in either of such
          Registration Statements and the Prospectus and take no
          responsibility therefor, except insofar as set forth in paragraph
          4 hereof.  In passing upon the forms of such Registration
          Statements and the Prospectus we have, therefore, assumed the
          accuracy and completeness of such representations, statements and
          information, except as aforesaid.  However, our examination of
          such Registration Statements and the Prospectus and our
          discussions in the above-mentioned conferences did not disclose
          to us any information which gives us reason to believe that, when
          each of the Initial and the Subsequent Registration Statements
          became effective, it contained an untrue statement of a material
          fact or omitted to state a material fact required to be stated
          therein or necessary to make the statements therein not
          misleading, or that, as of the date of this opinion, the
          Prospectus includes an untrue statement of a material fact or
          omits to state a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which
          they were made, not misleading; provided, that we do not express
          any belief as to the financial statements or other financial or
          statistical data contained in such Registration Statements or the
          Prospectus, or as to the Forms T-1 or T-2, or as to any
          information contained therein furnished to the Company in writing
          by any of you expressly for use therein.

                    This opinion is limited to the facts and law at the
          date hereof.  In rendering the opinions set forth in paragraphs 7
          and 9 above, we have necessarily assumed that, at the time of any
          issuance, sale and delivery of a Note (i) the Board of Directors
          of the Company (or any committee thereof acting pursuant to
          authority properly delegated to such committee by the Board of
          Directors) has not taken any action to rescind or otherwise
          reduce its prior authorization of the issuance of the Notes and
          an officer of the Company, as stated in the resolutions of the
          Board of Directors (or any such committee) relating to the Notes,
          has executed and delivered such Notes, (ii) the orders of the
          OPUC and the WUTC with respect to the Notes remain in full force
          and effect and have not been modified or amended by the OPUC or
          the WUTC, respectively, and the Company complies with the terms
          of such orders and (iii) the orders of the SEC with respect to
          the Initial Registration Statement, the Subsequent Registration
          Statement, the Mortgage and the Indenture remain in full force
          and effect and have not been modified or amended by the SEC.

                    We are members of the bar of the State of New York and
          do not hold ourselves out as experts on the laws of the State of
          Oregon or the State of Washington. Accordingly, in rendering this
          opinion, we have relied, with your consent, as to all matters
          governed by the laws of the State of Oregon, upon the opinion of
          even date herewith addressed to you by Mark S. Dodson, Esq.,
          General Counsel of the Company, and, as to all matters governed
          by the laws of the State of Washington, upon the opinion of Stoel
          Rives LLP, special Washington counsel to the Company.  We
          understand that you are relying upon the opinions of Mark S.
          Dodson, Esq., and Stoel Rives LLP as to all matters governed by
          the laws of the State of Oregon and Washington, as the case may
          be, including titles to property and franchises and the lien of
          the Mortgage, upon which we do not pass.

                    You, the Trustees, and as to matters governed by the
          laws of the State of New York and the 1933 Act, the Exchange Act
          and the Trust Indenture Act, Mark S. Dodson, Esq., may rely upon
          this opinion in connection with the issuance and sale of the
          Notes.  Neither you nor any of them may rely upon this opinion
          for any other purpose, and no other person may rely upon this
          opinion for any purpose without, in each case, our prior written
          consent.

                                             Very truly yours,

          Dear Sirs:

                    With reference to the issuance and sale from
          time-to-time by Northwest Natural Gas Company (the "Company"),
          pursuant to the Distribution Agreement, dated  . , 1998 (the
          "Agreement"), between the Company and each of you, of not to
          exceed $143,000,000 in aggregate principal amount of (i) the
          Company's First Mortgage Bonds, designated Secured Medium-Term
          Notes, Series B (the "Secured Notes") to be issued under the
          Company's Mortgage and Deed of Trust, dated as of July 1, 1946,
          to Bankers Trust Company (the "Corporate Trustee") and R.G. Page
          (Stanley Burg, successor), as trustees, as supplemented by twenty
          supplemental indentures (such Mortgage and Deed of Trust, as so
          supplemented, being hereinafter called the "Mortgage"), and (ii)
          the Company's Unsecured Medium-Term Notes, Series B  (the
          "Unsecured Notes"), to be issued under the Company's Indenture,
          dated as of June 1, 1991 (the "Indenture"), to Bankers Trust
          Company, as trustee (the "Indenture Trustee") (the Secured Notes
          and the Unsecured Notes being hereinafter collectively referred
          to as the "Notes"), and the appointment of each of you as agents
          of the Company pursuant to the Agreement for the purposes  of
          soliciting and receiving offers to purchase Notes, as agents, and
          purchasing Notes, as principals, from the Company, please be
          advised that, as special Washington counsel to the Company, we
          have reviewed (a) the Mortgage; (b) the Indenture; (c) the
          Agreement; and (d) the proceedings before the Washington
          Utilities and Transportation Commission (the "WUTC") relating to
          the issuance and sale of the Notes.  We have also examined such
          other documents and satisfied ourselves as to such other matters
          as we have deemed necessary in order to render this opinion.  We
          have not examined the Notes, except for forms thereof.

                    In preparation of this opinion, we have examined
          originals or photostatic copies of such certificates, agreements,
          documents and other papers, and have made such inquiries and
          investigations of law, as we deemed appropriate and necessary for
          the opinion hereinafter set forth.  In our examination, we have
          assumed the authenticity of all documents submitted to us as
          certified or photostatic copies and the authenticity of the
          originals of such latter documents.  We have also assumed that
          the Mortgage, the Indenture and the Agreement have been duly
          authorized, executed and delivered by, and are legally binding
          on, each of the parties thereto.

                    As to certain matters of fact material to the opinion
          expressed herein, we have relied upon certificates of various
          corporate officers of the Company and public officials.  We
          assume the accuracy of the material and factual matters contained
          therein.

                    Based upon the foregoing and subject to the following
          qualifications, we are of the opinion that:

                    (1)  The Company is authorized to transact business in
               the State of Washington.

                    (2)  The Mortgage constitutes a first security interest
               on all of the personal properties and fixtures owned by the
               Company in the State of Washington that are described in the
               Mortgage and are intended to be subject to the lien thereof,
               subject only to Excepted Encumbrances (as defined in the
               Mortgage); and the description in the Mortgage of such
               properties and fixtures is adequate to constitute the
               Mortgage a security interest thereon.

                    (3)  The Company has good and sufficient title to all
               of the real properties owned by the Company in the State of
               Washington that are described in the Mortgage and intended
               to be subject to the lien thereof, subject only to Excepted
               Encumbrances (as defined in the Mortgage) and to minor
               defects and irregularities of the nature customarily found
               in properties of like size and character; the description in
               the Mortgage of such properties is adequate to constitute
               the Mortgage a lien thereon; and the Mortgage is a valid
               first mortgage lien on such properties, subject to the
               exceptions noted above in this paragraph (3).

                    (4)  The issuance and sale of the Notes, the compliance
               by the Company with all of the provisions of the Notes, the
               Mortgage, the Indenture and the Agreement and the
               consummation of the transactions contemplated by the
               Agreement will not violate any law, rule or regulation of
               the State of Washington or any political subdivision thereof
               known to us to be applicable to the Company.

                    (5)  The WUTC has issued orders dated January 22, 1997
               in Docket UG-961639 and dated June 25, 1998 in Docket UG-
               980812, establishing compliance with applicable statutory
               provisions with respect to the issuance and sale by the
               Company of the Notes; and under the laws of the State of
               Washington, no further approval, authorization, consent or
               other order of any public board or body is legally required
               for the issuance and sale of the Notes through each of you,
               as agent, on the terms and conditions set forth in the
               Agreement.

                    This opinion is limited to the facts and law at the
          date hereof.  In rendering the opinions set forth in paragraphs 4
          and 5 above, we have necessarily assumed that, at the time of any
          issuance, sale and delivery of a Note (i) the Board of Directors
          of the Company (or any committee thereof acting pursuant to
          authority properly designated to such committee by the Board of
          Directors) has not taken any action to rescind or otherwise
          reduce its prior authorization of the issuance of the Notes and
          an officer of the Company, as stated in the resolutions of the
          Board of Directors (or any such committee) relating to the Notes,
          has executed and delivered such Notes and (ii) the orders of the
          WUTC with respect to the Notes remain in full force and effect
          and have not been modified or amended by the WUTC and the Company
          complies with the terms of such orders.

                    We are members of the bar of the State of Washington
          and do not express any opinion herein concerning any laws other
          than the laws of the State of Washington.

                    In giving the foregoing opinions, we express no opinion
          as to the securities or blue sky laws of any jurisdiction.

                    You, the Trustees, Mark S. Dodson, Esq., General
          Counsel of the Company, Thelen Reid & Priest LLP, counsel to the
          Company, and your counsel, as to matters governed by the laws of
          the State of Washington, may rely upon this opinion in connection
          with the issuance and sale of the Notes. Neither you nor any of
          them may rely upon this opinion for any other purpose, and no
          other person may rely upon this opinion for any purpose without,
          in each case, our prior written consent.

                                        Very truly yours,

                                                                   ANNEX VI


                [Contents of Letter of Independent Public Accountants]


                    The letter of each independent public accountant will
          state in effect that, for the periods during which such firm was
          the independent public accountant for the Company: 

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

                    2.   In their opinion, the financial statements
          examined by them and incorporated by reference in the
          Registration Statement comply as to form in all material respects
          with the applicable accounting requirements of the Exchange Act
          and the published rules and regulations thereunder; 

                    3.   On the basis of limited procedures, not
          constituting an examination made in accordance with generally
          accepted auditing standards, including a reading of the latest
          available interim financial statements of the Company, if any, a
          reading of the minute books of the Company since December 31,
          19__, inquiries of officials of the Company responsible for
          financial and accounting matters and such other inquiries and
          procedures as may be specified in such letter, nothing came to
          their attention that caused them to believe that: 

                         (a)(1)  the latest interim consolidated financial
               statements included or incorporated by reference in the
               Registration Statement do not comply as to form in all
               material respects with the applicable accounting
               requirements of the Exchange Act and the published rules and
               regulations thereunder as they apply to Form 10-Q or (2)
               said interim consolidated financial statements are not in
               conformity with generally accepted accounting principles
               applied on a basis substantially consistent with that of the
               audited consolidated financial statements incorporated by
               reference in the Registration Statement; 

                         (b)  at the date of the latest available interim
               balance sheet of the Company and at a subsequent specified
               date not more than five days prior to the Time of Delivery,
               there has been any change in the capital stock (except for
               (I) shares of the Company's Common Stock issued under the
               Company's Dividend Reinvestment Plan, 1985 Stock Option Plan
               or Employee Stock Purchase Plan, (II) shares of Common Stock
               issued upon the conversion of shares of the Company's
               Convertible Debentures, and (III) shares of Preferred Stock
               purchased or redeemed pursuant to or in anticipation of
               sinking and purchase funds with respect to the Company's
               Preferred Stock) or any increase in the long-term debt of
               the Company, or any decrease in net assets, in each case as
               compared with amounts shown in the balance sheet as of the
               date of the latest financial statements incorporated by
               reference in the Registration Statement, except in each case
               for changes, increases or decreases which the Registration
               Statement discloses have occurred or may occur, which were
               occasioned by the declaration of dividends or which are
               described in such letter; or 

                         (c)  for the latest period for which financial
               information is available subsequent to the latest financial
               statements included or incorporated by reference in the
               Prospectus, there were any decreases in operating revenues,
               net income and earnings available for common stock, as
               compared to the corresponding period in the prior year,
               except in each case for decreases which the Registration
               Statement discloses have occurred or may occur, which were
               occasioned by the declaration of dividends or which are
               described in such letter; and

                    4.   They have performed certain other specified
          procedures with respect to certain amounts and percentages set
          forth in the Registration Statement or in the documents
          incorporated by reference therein, as have been requested by your
          counsel and approved by the Company, and have found them to be in
          agreement with the records of the Company and the computations to
          be arithmetically correct.

          Date specified above or from the most recent interest payment

          on each Interest Payment Date specified above of each year,
          commencing on the interest payment date next succeeding the Issue
          Date, until the Company's obligation with respect to the payment
          of such principal shall have been discharged; provided, however,
          that if the date of this bond shall be after a record date with
          respect to any interest payment date and prior to such interest
          payment date, interest shall be payable to such registered holder
          only from such interest payment date; and provided, further, that
          (i) if the Issue Date shall be after a record date with respect
          to any interest payment date and prior to the corresponding

          interest payment date succeeding the Issue Date, and (ii)
          interest payable on the Maturity Date will be payable to the
          person to whom such principal shall be payable.

                    This bond is one of an issue of bonds of the Company
          issuable in series and is one of a series known as its First
          Mortgage Bonds, Secured Medium-Term Notes, Series B, all bonds of
          all series issued and to be issued under and equally secured
          (except in so far as any sinking or other fund, established in
          accordance with the provisions of the Mortgage hereinafter
          mentioned, may afford additional security for the bonds of any
          particular series) by a Mortgage and Deed of Trust (herein,
          together with any indenture supplemental thereto, including the
          supplemental indenture dated as of June 1, 1993, called the
          Mortgage) dated as of July 1, 1946, executed by Portland Gas &
          Coke Company (now Northwest Natural Gas Company) to Bankers Trust
          Company and R.G. Page (Stanley Burg, successor), as Trustees. 
          Reference is made to the Mortgage for a description of the
          property mortgaged and pledged, the nature and extent of the
          security, the rights of the holders of the bonds and of the
          Trustees in respect thereof, the duties and immunities of the
          Trustees, the terms and conditions upon which the bonds are and
          are to be secured, and the circumstances under which additional
          bonds may be issued.  With the consent of the Company and to the
          extent permitted by and as provided in the Mortgage, the rights
          and obligations of the Company and/or the rights of the holders
          of the bonds and/or coupons and/or the terms and provisions of
          the Mortgage may be modified or altered by the affirmative vote
          of the holders of at least seventy per centum (70%) in principal
          amount of the bonds then outstanding under the Mortgage and, if
          the rights of the holders of one or more, but less than all,
          series of bonds then outstanding are to be affected, then also by
          affirmative vote of the holders of at least seventy per centum
          (70%) in principal amount of the bonds then outstanding of each
          series of bonds so to be affected (excluding in any case bonds
          disqualified from voting by reason of the Company's interest
          therein as provided in the Mortgage); provided that, without the
          consent of the holder hereof, no such modification or alteration
          shall, among other things, impair or affect the right of the
          holder to receive payment of the principal of (and premium, if
          any) and interest on this bond, on or after the respective due
          dates expressed herein, or permit the creation of any lien equal
          or prior to the lien of the Mortgage or deprive the holder of the
          benefit of a lien on the mortgaged and pledged property.  The
          Company has the right, without any consent or other action by the
          holders of any series of bonds (including this series), to amend
          the Mortgage so as to change seventy per centum (70%) in the
          foregoing sentence to sixty-six and two-thirds per centum (66-
          2/3%).

                    The principal hereof may be declared or may become due
          prior to the Maturity Date hereinbefore named on the conditions,
          in the manner and at the time set forth in the Mortgage, upon the
          occurrence of a default as in the Mortgage provided.

                    The transfer of this bond may be registered as
          prescribed in the Mortgage by the registered owner hereof in
          person, or by his duly authorized attorney, at the office or
          agency of the Company in the Borough of Manhattan, The City of
          New York, upon surrender for cancellation of this bond, together
          with a written instrument of transfer wherever required by the
          Company duly executed by the registered owner or by his duly
          authorized attorney, and, thereupon, a new fully registered bond
          of the same series for a like principal amount and having the
          same Issue Date, Maturity Date and redemption provisions, if any,
          and bearing interest at the same rate, will be issued to the
          transferee in exchange herefor as provided in the Mortgage.  The
          Company and the Trustees may deem and treat the person in whose
          name this bond is registered as the absolute owner hereof for the
          purpose of receiving payment and for all other purposes and
          neither the Company nor the Trustees shall be affected by any
          notice to the contrary.

                    In the manner prescribed in the Mortgage, any bonds of
          this series, upon surrender thereof, for cancellation, at the
          office or agency of the Company in the Borough of Manhattan, The
          City of New York, are exchangeable for a like aggregate principal
          amount of bonds of the same series of other authorized
          denominations which have the same Issue Date, Maturity Date and
          redemption provisions, if any, and which bear interest at the
          same rate.

                    If so specified above, this bond is subject to
          redemption at any time on or after the Initial Redemption Date
          specified above, as a whole or, if specified above, in part, at
          the election of the Company, at the applicable redemption price
          (as described below or as set forth above under "Other
          Provisions") plus accrued interest to the date fixed for
          redemption.  Such redemption price shall be the Initial
          Redemption Price specified above for the twelve-month period
          commencing on the Initial Redemption Date and shall decline for
          the twelve-month period commencing on each anniversary of the
          Initial Redemption Date by a percentage of principal amount equal
          to the Reduction Percentage specified above until such redemption
          price is 100% of the principal amount of this bond.

                    Notwithstanding the foregoing, the Company may not,
          prior to the Redemption Limitation Date, if any, specified above,
          redeem this bond as contemplated above as a part of, or in
          anticipation of, any refunding operation by the application,
          directly or indirectly, of moneys borrowed having an effective
          interest cost to the Company (calculated in accordance with
          generally accepted financial practice) of less than the effective
          interest cost to the Company (similarly calculated) of this bond.

                    If so specified above, this bond is repayable by the
          Company at the option of the registered owner hereof on the
          Repayment Date or Dates and at the Repayment Price or Prices
          specified above, plus accrued interest to the date of repayment. 
          The repayment option may be exercised by the registered owner of
          this bond for less than its entire principal amount, provided
          that the principal amount to be repaid is equal to $1,000 or an
          integral multiple of $1,000.  For this bond to be repaid at the
          option of the registered owner hereof, the Company must receive
          this bond at its office or agency in the Borough of Manhattan,
          The City of New York, no later than the close of business on the
          last day of the Election Period or Periods specified above,
          together with the form entitled "Option to Elect Repayment" set
          forth below on, or otherwise accompanying, this bond, duly
          completed.  Any such election so received by the Company within
          any such Period shall be irrevocable.  If the last day of the
          Election Period or Periods specified above shall not be a
          business day, the Election Period or Periods shall end at the
          close of business on the next succeeding business day.

                    As provided in the Mortgage, the Company shall not be
          required to register transfers or make exchanges of bonds of any
          series for a period of ten days next preceding any interest
          payment date for bonds of such series, or next preceding any
          designation of bonds of such series to be redeemed, and the
          Company shall not be required to make transfers or exchanges of
          any bonds designated in whole or in part for redemption.

                    No recourse shall be had for the payment of the
          principal of or interest on this bond against any incorporator or
          any past, present or future subscriber to the capital stock,
          stockholder, officer or director of the Company or of any
          predecessor or successor corporation, as such, either directly or
          through the Company or any predecessor or successor corporation,
          under any rule of law, statute or constitution or by the
          enforcement of any assessment or otherwise, all such liability of
          incorporators, subscribers, stockholders, officers and directors
          being released by the holder or owner hereof by the acceptance of
          this bond and being likewise waived and released by the terms of
          the Mortgage.

                    This bond shall not become obligatory until Bankers
          Trust Company, the Corporate Trustee under the Mortgage, or its
          successor thereunder, shall have signed the form of
          authentication certificate endorsed hereon.

               United States federal income tax on the same amounts, at the
               same times and in the same manner as if such satisfaction

                    NORTHWEST NATURAL GAS COMPANY, a corporation duly
          organized and existing under the laws of the State of Oregon
          (herein called the "Company", which term includes any successor
          corporation under the Indenture referred to on the reverse
          hereof), for value received, hereby promises to pay to CEDE &
          Co., or registered assigns, the principal amount specified above
          on the Stated Maturity Date specified above, and to pay interest
          thereon from the Interest Commencement Date specified above or
          from the most recent Interest Payment Date to which interest has
          been paid or duly provided for, semi-annually in arrears on each
          Interest Payment Date specified above in each year, commencing
          (except as provided in the following sentence) with the Interest
          Payment Date next succeeding the Interest Commencement Date
          specified above, at the Interest Rate per annum specified above,
          until the principal hereof shall have been paid or duly provided
          for.  The interest so payable, and punctually paid or duly
          provided for, on any Interest Payment Date, as provided in such
          Indenture, shall be paid to the Person in whose name this
          Security (or one or more Predecessor Securities) shall have been
          registered at the close of business on the Regular Record Date
          specified above (whether or not a Business Day) next preceding
          such Interest Payment Date; provided, however, that, if the
          Interest Commencement Date of this Security shall be after a
          Regular Record Date and before the corresponding Interest Payment
          Date, payment of interest shall commence on the second Interest
          Payment Date succeeding such Interest Commencement Date and shall
          be paid to the Person in whose name this Security was registered
          on the Regular Record Date for such second Interest Payment Date;
          and provided, further, that interest payable on the Stated
          Maturity Date specified above shall be paid to the Person to whom
          principal shall be paid.  Any such interest not so punctually
          paid or duly provided for shall forthwith cease to be payable to
          the Holder on such Regular Record Date and shall be paid as
          provided in said Indenture.

                    Payment of the principal of, and premium, if any, and
          interest on, this Security shall be made at the office or agency
          of the Company maintained for such purpose in the Borough of
          Manhattan, The City of New York, New York, in such coin or
          currency of the United States of America as at the time of
          payment shall be legal tender for payment of public and private
          debts; provided, however, that, at the option of the Company,
          payment of interest may be made by check mailed to the address of
          the Person entitled thereto as such address shall appear in the
          Security Register; and provided further, that payment of
          principal, and premium, if any, and interest, payable on the
          Stated Maturity Date specified above or upon redemption, at the
          request of the Holder, will be made at said office or agency in
          immediately available funds upon presentation of this Security.

                    This Security is one of a duly authorized issue of
          securities of the Company (herein called the "Securities"),
          issued and issuable in one or more series under an Indenture,
          dated as of June 1, 1991 (such Indenture, as originally executed
          and delivered and as thereafter supplemented and amended,
          together with any constituent instruments establishing the terms
          of particular Securities, being herein called the "Indenture"),
          from the Company to Bankers Trust Company, as trustee (herein
          called the "Trustee", which term includes any successor trustee
          under the Indenture), to which Indenture reference is hereby made
          for a statement of the respective rights, limitations of rights,
          duties and immunities thereunder of the Company, the Trustee and
          the Holders of the Securities and of the terms upon which the
          Securities have been, and will be, authenticated and delivered. 
          The acceptance of this Security shall be deemed to constitute the
          consent and agreement by the Holder hereof to all of the terms
          and provisions of the Indenture.  This Security is one of the
          series designated on the face hereof.

                    If any Interest Payment Date, any Redemption Date or
          the Stated Maturity Date shall not be a Business Day, payment of
          the amounts due on this Security on such date may be made on the
          next succeeding Business Day; and no interest shall accrue on
          such amounts for the period from and after such Interest Payment
          Date, Redemption Date or Stated Maturity Date, as the case may
          be.

                    If so specified above, this Security is subject to
          redemption at any time on or after the Initial Redemption Date
          specified above, as a whole or, if so specified, in part, at the
          election of the Company, at the applicable redemption price (as
          described in the following sentence or as set forth above under
          "Other Provisions") plus accrued interest to the date fixed for
          redemption.  Such redemption price shall be the Initial
          Redemption Price specified above for the twelve-month period
          commencing on the Initial Redemption Date and shall decline for
          the twelve-month period commencing on each anniversary of the
          Initial Redemption Date by a percentage of principal amount equal
          to the Reduction Percentage specified above until such redemption
          price is 100% of the principal amount of this Security to be
          redeemed.

                    Notwithstanding the foregoing, the Company may not,
          prior to the Redemption Limitation Date, if any, specified above,
          redeem this Security as contemplated above as a part of, or in
          anticipation of, any refunding operation by the application,
          directly or indirectly, of moneys borrowed having an effective
          interest cost to the Company (calculated in accordance with
          generally accepted financial practice) of less than the effective
          interest cost to the Company (similarly calculated) of this
          Security.

                    Notice of redemption shall be given by mail to Holders
          of Securities, not less than 30 days nor more than 90 days prior
          to the date fixed for redemption, all as provided in the
          Indenture.  As provided in the Indenture, notice of redemption as
          aforesaid may state that such redemption shall be conditional
          upon the receipt by the Trustee of money sufficient to pay the
          Redemption Price of, and interest, if any, on, this Security on
          or prior to the date fixed for such redemption.  A notice of
          redemption so conditioned shall be of no force or effect if such
          money is not so received; and, in such event, the Company shall
          not be required to redeem this Security.

                    The Company shall not be required to (a) register the
          transfer of or exchange Securities of this series and Tranche
          during a period of 15 days immediately preceding the selection of
          Securities of this series and Tranche to be called for redemption
          or (b) issue, register the transfer of or exchange any Security
          so selected for redemption, in whole or in part, except the
          unredeemed portion of any Security being redeemed in part.

                    In the event of redemption of this Security in part
          only, a new Security or Securities of this series and Tranche of
          authorized denominations, of like tenor and in aggregate
          principal amount equal to the unredeemed portion hereof will be
          issued in the name of the Holder hereof upon the surrender of
          this Security.

                    If so specified above, this Security is repayable by
          the Company at the option of the Holder hereof on the Repayment
          Date or Dates and at the Repayment Price or Prices specified
          above, plus accrued interest to the date of repayment.  The
          repayment option may be exercised by the Holder of this Security
          for less than its entire principal amount, provided that the
          principal amount to be repaid is equal to $1,000 or an integral
          multiple of $1,000.  For this Security to be repaid at the option
          of the Holder hereof, the Company must receive this Security at
          its office or agency in the Borough of Manhattan, The City of New
          York, no later than the close of business on the last day of the
          Election Period or Periods specified above, together with the
          form entitled "Option to Elect Repayment" set forth below on, or
          otherwise accompanying, this Security, duly completed.  Any such
          election so received by the Company within any such Period shall
          be irrevocable.  If the last day of the Election Period or
          Periods specified above shall not be a business day, the Election
          Period or Periods shall end at the close of business on the next
          succeeding business day.

                    The Indenture contains provisions for defeasance at any
          time of the entire indebtedness of this Security upon compliance
          with certain conditions set forth in the Indenture.

                    If an Event of Default with respect to Securities of
          this series shall occur and be continuing, the principal of the
          Securities of this series may be declared due and payable in the
          manner and with the effect provided in the Indenture.

                    The Indenture permits, with certain exceptions as
          therein provided, the Trustee to enter into one or more
          supplemental indentures for the purpose of adding any provisions
          to, or changing in any manner or eliminating any of the
          provisions of, the Indenture with the consent of the Holders of
          not less than a majority in aggregate principal amount of the
          Securities of all series then Outstanding under the Indenture,
          considered as one class; provided, however, that if there shall
          be Securities of more than one series Outstanding under the
          Indenture and if a proposed supplemental indenture shall directly
          affect the rights of the Holders of Securities of one or more,
          but less than all, of such series, then the consent only of the
          Holders of a majority in aggregate principal amount of the
          Outstanding Securities of all series so directly affected,
          considered as one class, shall be required; and provided,
          further, that if the Securities of any series shall have been
          issued in more than one Tranche and if the proposed supplemental
          indenture shall directly affect the rights of the Holders of
          Securities of one or more, but less than all, of such Tranches,
          then the consent only of the Holders of a majority in aggregate
          principal amount of the Outstanding Securities of all Tranches so
          directly affected, considered as one class, shall be required. 
          The Indenture also contains provisions permitting the Holders of
          specified percentages in principal amount of the Securities of
          any series then Outstanding, on behalf of the Holders of all
          Securities of such series, to waive compliance by the Company
          with certain provisions of the Indenture and certain past
          defaults under the Indenture and their consequences.  Any such
          consent or waiver by the Holder of this Security shall be
          conclusive and binding upon such Holder and upon all future
          Holders of this Security and of any Security issued upon the
          registration of transfer hereof or in exchange therefor or in
          lieu hereof, whether or not notation of such consent or waiver is
          made upon this Security.

                    No reference herein to the Indenture and no provision
          of this Security or of the Indenture shall alter or impair the
          obligation of the Company, which is absolute and unconditional,
          to pay the principal of, and premium, if any, and interest, on,
          this Security at the times, place and rate, in the coin or
          currency, and in the manner, herein prescribed.

                    As provided in the Indenture and subject to certain
          limitations therein set forth, the transfer of this Security is
          registrable in the Security Register, upon surrender of this
          Security for registration of transfer at the Corporate Trust
          Office of the Trustee or such other office or agency as may be
          designated by the Company for such purpose in the Borough of
          Manhattan, The City of New York, New York, duly endorsed by, or
          accompanied by a written instrument of transfer in form
          satisfactory to the Company and the Security Registrar duly
          executed by, the Holder hereof or his attorney duly authorized in
          writing, and, thereupon, one or more new Securities of this
          series and Tranche of authorized denominations and of like tenor
          and aggregate principal amount will be issued to the designated
          transferee or transferees.

                    The Securities of this series are issuable only as
          Registered Securities, without coupons, in denominations of
          $1,000 and any amount in excess thereof that is an integral
          multiple of $1,000.  As provided in the Indenture and subject to
          certain limitations therein set forth, Securities of this series
          and Tranche are exchangeable for a like aggregate principal
          amount of Securities of the same series and Tranche, of any
          authorized denominations, requested by the Holder surrendering
          the same, and of like tenor upon surrender of the Security or
          Securities to be exchanged at the Corporate Trust Office of the
          Trustee or such other office or agency as may be designated by
          the Company for such purpose in the Borough of Manhattan, The
          City of New York, New York.

                    No service charge shall be made for any such
          registration of transfer or exchange, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge payable in connection therewith.

                    Prior to due presentment of this Security for registra-
          tion of transfer, the Company, the Trustee and any agent of the
          Company or the Trustee may treat the Person in whose name this
          Security is registered as the absolute owner hereof for all
          purposes, whether or not this Security be overdue, and neither
          the Company, the Trustee nor any such agent shall be affected by
          notice to the contrary.

                    The Indenture and the Securities shall be governed by
          and construed in accordance with the laws of the State of New
          York.

                    All terms used in this Security which are defined in
          the Indenture shall have the meanings assigned to them in the
          Indenture.

                    As provided in the Indenture, no recourse shall be had
          for the payment of the principal of, or premium, if any, or
          interest on, any Securities, or any part thereof, or for any
          claim based thereon or otherwise in respect thereof, or of the
          indebtedness represented thereby, or upon any obligation,
          covenant or agreement under the Indenture, against any
          incorporator, stockholder, officer or director, as such, past,
          present or future, of the Company or of any predecessor or
          successor corporation (either directly or through the Company or
          a predecessor or successor corporation), whether by virtue of any
          constitutional provision, statute or rule of law, or by the
          enforcement of any assessment or penalty or otherwise; it being
          expressly agreed and understood that the Indenture and all the
          Securities are solely corporate obligations, and that no personal
          liability whatsoever shall attach to, or be incurred by, any
          incorporator, stockholder, officer or director, as such, past,
          present or future of the Company or of any predecessor or
          successor corporation (either directly or through the Company or
          a predecessor or successor corporation), because of the
          indebtedness thereby authorized or under or by reason of any of
          the obligations, covenants or agreements contained in the
          Indenture or in any of the Securities or to be implied herefrom
          or therefrom, and that any such personal liability is hereby
          expressly waived and released as a condition of, and as part of
          the consideration for, the execution of the Indenture and the
          issuance of the Securities.

                    Unless the certificate of authentication hereon has
          been executed by the Trustee by manual signature, this Security
          shall not be entitled to any benefit under the Indenture or be
          valid or obligatory for any purpose.

                       [Letterhead of Mark S. Dodson, Esq.]
                  



                                                September 29, 1998




             Northwest Natural Gas Company
             220 N.W. Second Avenue
             Portland, Oregon  97209

             Ladies and Gentlemen:

                       With respect to the Registration Statement on
             Form S-3 to be filed with the Securities and Exchange
             Commission (the "Commission") on or about the date hereof
             by Northwest Natural Gas Company (the "Company") for the
             registration under the Securities Act of 1933, as amended
             ("Securities Act"), of $100,000,000 aggregate principal
             amount of Secured Medium-Term Notes, Series B ("Secured
             Notes") and Unsecured Medium-Term Notes, Series B
             ("Unsecured Notes") (the Secured Notes and the Unsecured
             Notes are hereinafter collectively referred to as the
             "Notes") to be issued by the Company, and for the
             qualification under the Trust Indenture Act of 1939, as
             amended ("Trust Indenture Act"), of the Company's Mortgage
             and Deed of Trust, as supplemented ("Mortgage"), under
             which the Secured Notes are to be issued, and the Company's
             Indenture ("Indenture") under which the Unsecured Notes are
             to be issued, I am of the opinion that:

                  1.   The Company is a corporation duly organized and
             validly existing under the laws of the State of Oregon.

                  2.   All action necessary to make the Notes legally
             issued and valid and binding obligations of the Company
             will have been taken when:

                       (a)  the Company's Registration Statement on
                            Form S-3, as it may be amended, shall have
                            become effective in accordance with the
                            applicable provisions of the Securities Act,
                            and a supplement or supplements to the
                            Prospectus constituting a part of the
                            Registration Statement specifying certain
                            details with respect to the offering or
                            offerings of the Notes shall have been filed
                            with the Commission, and the Mortgage and
                            the Indenture shall have been qualified
                            under the Trust Indenture Act; and

                       (b)  the Notes shall have been appropriately
                            issued and delivered for the consideration
                            contemplated by, and otherwise in conformity
                            with, the acts, proceedings and documents
                            referred to above, the authorizing
                            resolutions of the Board of Directors of the
                            Company and the orders of the Public Utility
                            Commission of Oregon and the Washington
                            Utilities and Transportation Commission
                            relating to the Notes.

                       I am a member of the bar of the State of Oregon,
             but not of the State of Washington.  In rendering this
             opinion, I have made such reviews of the laws of the State
             of Washington and had such consultations with the Company's
             Washington State counsel as I believe necessary to satisfy
             myself as to questions of Washington law.  As to all
             matters of New York law, I have relied upon an opinion of
             even date herewith addressed to you by Thelen Reid & Priest
             LLP which is filed as Exhibit 5(b) to the Registration
             Statement.

                       I hereby consent to the use of this opinion as an
             exhibit to the Registration Statement, as it may be
             amended, and consent to such references to me as may be
             made in such Registration Statement and in the Prospectus.

                                                Very truly yours,


                                                /s/ Mark S. Dodson

                                                Mark S. Dodson, Esq.

             220 N.W. Second Avenue
             Portland, Oregon  97209

             Ladies and Gentlemen:

                       With respect to the Registration Statement on
             Form S-3 to be filed with the Securities and Exchange
             Commission (the "Commission") on or about the date hereof

             amount of Secured Medium-Term Notes, Series B ("Secured
             Notes") and Unsecured Medium-Term Notes, Series B
             ("Unsecured Notes")(the Secured Notes and the Unsecured
             Notes are hereinafter collectively referred to as the
             "Notes") to be issued by the Company, and for the
             qualification under the Trust Indenture Act of 1939, as

             Indenture ("Indenture") under which the Unsecured Notes are
             to be issued, we are of the opinion that:

                  1.   The Company is a corporation duly organized and
             validly existing under the laws of the State of Oregon.

                  2.   All action necessary to make the Notes legally

             will have been taken when:

                       (a)  the Company's Registration Statement on
                            Form S-3, as it may be amended, shall have
                            become effective in accordance with the
                            applicable provisions of the Securities Act
                            and a supplement or supplements to the
                            Prospectus constituting a part of the
                            Registration Statement specifying certain

                            offerings of the Notes shall have been filed
                            with the Commission, and the Mortgage and
                            the Indenture shall have been qualified
                            under the Trust Indenture Act; and

                       (b)  the Notes shall have been appropriately
                            issued and delivered for the consideration
                            contemplated by, and otherwise in conformity
                            with, the acts, proceedings and documents
                            referred to above, the authorizing
                            resolutions of the Board of Directors of the
                            Company and the orders of the Public Utility

             hold ourselves out as experts on the laws of any other
