                                   THE COMPANY

      The  Company, which was  incorporated under the  laws of  Oregon in 1910,
   distributes natural  gas to  customers in  western Oregon and  southwestern
   Washington,  including the  Portland  metropolitan area.    Gas service  is
   provided  in 95 cities and  neighboring communities in  16 Oregon counties,
   and  in  nine  cities  and  neighboring  communities  in  three  Washington
   counties.   The  Company's service  areas have  a population  of 2,600,000,
   including about 78 percent of the  population of the State of Oregon.   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.

      Oregon Natural  Development  Corporation, a  wholly-owned subsidiary,  is
   engaged in  natural  gas exploration,  development  and production  in  the
   western United States and Canada.

      NNG  Financial   Corporation,  another   wholly-owned  subsidiary,  holds
   financial  investments  as  a  limited  partner   in  four  solar  electric
   generating systems, four windmill projects and a hydroelectric project, all
   located in California,  and in  a low-income housing  project in  Portland.
   NNG  Financial  also  arranges   short-term  financing  for  the  Company's
   operating subsidiaries.


                        RATIO OF EARNINGS TO FIXED CHARGES

      The Company  has  calculated the  ratios  of  earnings to  fixed  charges
   pursuant to Item 503 of SEC Regulation S-K as follows:
   

                                    Twelve Months Ended

                       ----     ----   ----    ----    ----    ----
                       2.94     3.22   1.81    1.59    2.64    2.75

      Earnings consist of net  income to which have  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.


                      USE OF PROCEEDS AND FINANCING PROGRAM

      The net  proceeds to  be received  by the  Company from  the sale of  the
   Securities 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 and to repay short-term debt incurred for such
   purpose.

      The Company expects  its utility construction and equipment  expenditures
   in 1994 to aggregate  $75 million.  The  Company expects such  expenditures
   for  the five-year period, 1994-98,  to aggregate between  $325 million and
   $350 million.  The capital requirements of its subsidiaries during the same
   period  are expected  to be limited  to funds  internally generated  by the
   subsidiaries.   Approximately $21 million of long-term debt matures in 1996
   and $26 million in 1997.

      The Company estimates that 50% or more of the funds required for  utility
   purposes  during the 1994-98 period  will be internally  generated and that
   the balance, as  well as substantially  all of the  funds required for  the
   repayment of maturing  debt, will be funded  through short-term borrowings,
   which  will be refinanced periodically  through the sale  of long-term debt
   and  equity securities, in such amounts and  at such times as the Company's
   cash requirements and market  conditions shall determine.  Based  upon this
   estimate, the Company expects that, through the end of 1995, its sales of 
   Common Stock will not  exceed $50 million, consisting  of not more than  
   $40 million of New Common Stock and approximately $10 million of Common 
   Stock expected to be  sold  through its  Dividend Reinvestment  and  Stock 
   Purchase  Plan and various employee plans.


                           DESCRIPTION OF THE NEW BONDS

      General:   The New Bonds  are to be  issued under  the Company's Mortgage
   and Deed of Trust, dated as  of July 1, 1946, to Bankers Trust  Company and
   R.G. Page (Stanley Burg, successor), as trustees, as supplemented by twenty
   supplemental  indentures and as to  be further supplemented  by one or more
   additional  supplemental indentures providing for one or more series of the
   New Bonds, all of which are collectively referred to as the "Mortgage".

      The  statements herein  concerning the  New  Bonds  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.

      Reference is made to the Prospectus Supplement for  each issue of the New
   Bonds  for the  following terms, among  others, of  the New   Bonds offered
   thereby: (i) the series designation and aggregate principal amount thereof,
   (ii) the initial  public offering price and other  terms of their offering,
   (iii) the  date or dates on which they will  mature, (iv) the rate or rates
   per annum  at which they will  bear interest, (v)  the times at  which such
   interest  will be  payable and  the date  from which  it will  accrue, (vi)
   whether  all  or  any  portion  thereof  will  be issued  to  a  designated
   depositary,  (vii) any  redemption  provisions, and  (viii) other  specific
   terms.

      Form,  Exchange  and  Payment:    Unless   otherwise  indicated  in   the
   Prospectus Supplement  for an issue of the New Bonds, the New Bonds offered
   thereby will  be issued only  in fully registered form  in denominations of
   $1,000 and  any multiple thereof.   The New  Bonds are exchangeable  at the
   office of Bankers Trust Company in New York City, without charge other than
   taxes or  other  governmental  charges incident  thereto.    Principal  and
   interest are payable at such office.

      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  First  Mortgage Bonds  ("Bonds")
   pursuant to these provisions.

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

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

      The  Mortgage provides  that the  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;  (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
   March  31,  1994,  approximately  $201,300,900 of  property  additions  and
   $93,000,000 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  New Bonds  will be  issued  against  property additions  and retired
   Bonds.

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

      Release and Substitution of Property:   Property may be released  against
   (1) deposit of cash or, to a limited extent, purchase  money mortgages, (2)
   property additions,  or  (3) waiver  of the  right to  issue Bonds  without
   applying any  earnings test.  Cash so  deposited and cash deposited against
   the issuance of additional bonds may be withdrawn upon the  bases stated in
   (2) and (3) above.  When property released is not funded property, property
   additions used  to effect the release  may again, in certain  cases, become
   available as credits  under the Mortgage,  and the waiver  of the right  to
   issue  Bonds to  effect the  release  may, in  certain cases,  cease to  be
   effective as such  a waiver.  Similar  provisions are in effect as  to cash
   proceeds of such property.   The Mortgage contains special  provisions with
   respect  to  qualified lien  bonds pledged  and  the disposition  of moneys
   received on pledged prior lien  bonds.  (See Mortgage, Secs. 5, 31, 32, 37,
   46 to 50, 59 to 61, 100 and 118.)

      Defaults  and Notice  Thereof:   Defaults  are:   default  in payment  of
   principal; default for 60 days in payment of interest or of installments of
   funds for retirement of  bonds; certain defaults with respect  to qualified
   lien bonds; certain events in bankruptcy, insolvency or reorganization; and
   default for  90 days  after notice  in the case  of other  covenants.   The
   trustees  may withhold notice of  default (except in  payment of principal,
   interest  or any funds 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 trustees written notice of a default  and unless holders
   of 25%  of the Bonds  have requested the trustees  to act and  offered them
   reasonable opportunity to  act and the  trustees have failed  to act.   The
   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.  The holders of a majority of the Bonds may direct the
   time,  method  and  place of  conducting  any  proceedings  for any  remedy
   available  to the trustees, or exercising any trust or power conferred upon
   the trustees but the 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  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 accounting,
   engineer,  appraiser  or  other  expert   must  be  independent.    Various
   certificates and  other  papers, including  a certificate  with respect  to
   compliance with the terms of the Mortgage and the absence  of defaults, are
   required  to be filed annually  and upon the  occurrence of certain events.
   (See Mortgage, Secs. 67, 71, 80 and 94).

      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 reserved  the right without any consent or other
   action  by holders of  any series of  Bonds (including the  New Bonds), and
   intends in  conjunction with the issuance  of the New Bonds,  to substitute
   66-2/3% for  70%.  In general, no modification of the terms of  payment of
   principal  and  interest, and  no modification  affecting  the lien  of the
   Mortgage or reducing the percentage required  for modification is 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 Eighteenth Series or
   of Bonds of any subsequently  created series (including the New  Bonds), in
   the following respects:

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

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


      The Corporate Trustee

             Bankers Trust Company also serves as  the Indenture Trustee under
      the Indenture under  which the Company's  Unsecured Medium-Term Notes are
      issued.


                           DESCRIPTION OF COMMON STOCK

     The following is a summary of certain rights and privileges of the Common
   Stock.  This summary does not purport to be complete.  Reference is made to
   the Restated Articles of Incorporation and the Bylaws of the Company, filed
   as  exhibits to the Registration  Statement, for complete  statements.  The
   following statements are qualified in their entirety by such references.

     Dividends  and Liquidation  Rights:   Except as  hereinafter stated,  the
   Common Stock is entitled to  receive such dividends as are declared  by the
   Board of Directors  and to receive ratably on liquidation  any assets which
   remain  after   payment  of  liabilities.    The  Company's  Preferred  and
   Preference  Stock are  entitled in preference  to the  Common Stock  (1) to
   cumulative dividends at the annual rate fixed for each series  by the Board
   of  Directors, and  (2) in  voluntary and  involuntary liquidation,  to the
   amounts fixed for each series by the Board of Directors, plus in each case,
   unpaid accumulated dividends.

     Dividend  Limitations:  Should dividends  on either the  Preferred or the
   Preference Stock be  in arrears, no  dividends on the  Common Stock may  be
   paid  or declared.  Except with the consent of the holders of a majority of
   the Preferred Stock  then outstanding, no dividends on the  Common Stock or
   the  Preference Stock may  be paid or  declared unless  the Preferred Stock
   purchase and sinking fund obligations have  been met for that year.  Future
   series of the Preferred or the Preference Stock could contain sinking fund,
   purchase or redemption obligations  under which no dividends on  the Common
   Stock may  be  paid or  declared  while such  obligations  are in  default.
   Common Stock dividends also may  be restricted by the provisions  of future
   instruments pursuant to which the Company may issue long-term debt.

     Voting Rights:  Except as provided by law or as described below, only the
   Common  Stock has  voting rights.   Cumulative voting  is permitted  by the
   Restated  Articles of Incorporation to holders of Common Stock at elections
   of  directors.   The Preferred  Stock has  the special  right to  elect the
   smallest number of directors  which constitutes at least one-fourth  of the
   total  number  of directors,  or two  directors,  whichever is  greater, if
   payments of  four quarterly  dividends or  more on any  share or  shares of
   Preferred Stock should be in arrears.

     Classification of the Board of Directors:   The Board of Directors of the
   Company  may consist of  not less  than nine nor  more than 13  persons, as
   determined  by the Board,  divided into  three classes  as nearly  equal in
   number as possible.   The current number  is twelve.  One  class is elected
   for a three-year term  at each annual meeting of  shareholders.  Vacancies,
   including those resulting from an increase in the size of the Board, may be
   filled by a majority vote of the directors then in office.  One or  more of
   the directors may  be removed, with  or without  cause, by the  affirmative
   vote of  the holders of not less than  two-thirds of the shares entitled to
   vote thereon; provided, however,  that if fewer  than all of the  directors
   should be  candidates for removal, no  one of them shall be  removed if the
   votes cast against  such director's  removal would be  sufficient to  elect
   such director  if then cumulatively  voted at an  election of the  class of
   directors of which such director shall be a part.  Except for those persons
   nominated  by the  Board, no  person shall  be eligible  for election  as a
   director  unless a  request  from a  shareholder  entitled to  vote  in the
   election  of  directors that  such person  be  nominated and  such person's
   consent  thereto shall  be delivered  to the  Secretary of  the Company  in
   advance of the meeting at which such election shall be held.  The foregoing
   provisions may not be amended or repealed except by the affirmative vote of
   the holders of  not less than two-thirds of the shares  entitled to vote at
   an  election of  directors.   The foregoing  provisions  will not  apply to
   directors, if any, elected by the holders of the Preferred Stock.

     Transactions with Related Persons:  The Company shall  not enter into any
   business transaction with  a related person  or in which  a related  person
   shall  have an  interest (except  proportionately as  a shareholder  of the
   Company)  without  first obtaining  both (1)  the  affirmative vote  of the
   holders  of not  less  than two-thirds  of the  outstanding  shares of  the
   capital stock of the  Company not held by such related  person, and (2) the
   determination of  a majority of  the continuing directors that  the cash or
   fair market value of the property, securities or other consideration to  be
   received  per share by the holders, other  than such related person, of the
   shares  of each class or series of the capital stock of the Company in such
   business transaction shall not be less than the highest purchase price paid
   by  such related person in acquiring  any of its holdings  of shares of the
   same class or  series, unless the  continuing directors by a  majority vote
   shall either (a) have  expressly approved the acquisition of  the shares of
   the capital stock of the Company that caused such related  person to become
   a related person, or (b) have expressly approved such business transaction.
   As  used in  this paragraph:   a "business transaction"  includes a merger,
   consolidation, reorganization or recapitalization, a purchase, sale, lease,
   exchange or  mortgage of  all or a  substantial part (10%  or more)  of the
   property of the Company or a  related person, an issuance, sale or exchange
   of securities and a  liquidation, spin-off or dissolution; a  "related per-
   son" includes a person, organization or group thereof owning 10% or more of
   the  capital stock of the  Company; "continuing directors"  are those whose
   nominations for directorship shall have been  approved by a majority of the
   directors in office on April 9, 1984  or by a majority of the then continu-
   ing directors.   The foregoing  provisions may not  be amended  or repealed
   except by the affirmative vote  of the holders of not less  than two-thirds
   of the  shares of the capital stock of the  Company (other than shares held
   by related persons).

     Preemptive  Rights:  The  holders of the Common  Stock have no preemptive
   rights.

     Other Provisions:  The issued and outstanding shares of Common Stock are,
   and the shares of  the New Common  Stock, if any, will  be, fully paid  and
   nonassessable.

     Transfer Agent  and Registrar:   The Company  is the  transfer agent  and
   registrar for the Common Stock. 



                               PLAN OF DISTRIBUTION

     The Company may  sell the Securities in  any of three ways:   (i) through
   underwriters or dealers; (ii) directly to a limited number of purchasers or
   to a single purchaser; or (iii) through agents.  Each Prospectus Supplement
   will set forth the terms of the offering of the Securities offered thereby,
   including the name or names of any underwriters, the purchase price of such
   Securities and the proceeds to the Company from such sale, any underwriting
   discounts  and other  items  constituting  underwriters' compensation,  any
   initial public offering price  and any discounts or concessions  allowed or
   reallowed or  paid to dealers.   Any initial public offering  price and any
   discounts or concessions  allowed or reallowed  or paid to  dealers may  be
   changed from time to time.

     If underwriters  are used in the sale, the Securities will be acquired by
   the underwriters for their own account and may be sold from time to time in
   one or  more transactions,  including negotiated  transactions, at  a fixed
   public offering  price or at varying  prices determined at the  time of the
   sale.   The  Securities  may  be  offered  to  the  public  either  through
   underwriting syndicates represented by one or more managing underwriters as
   may be designated by the Company, or directly by one or more of such firms.
   The underwriter or underwriters  with respect to a  particular underwritten
   offering  of Securities will be named in the Prospectus Supplement relating
   to  such offering and, if  an underwriting syndicate  is used, the managing
   underwriter or underwriters  will be set  forth on the  cover page of  such
   Prospectus  Supplement.    Unless  otherwise  set  forth  in  a  Prospectus
   Supplement, the  obligations of the underwriters to purchase the Securities
   offered  thereby will be subject  to certain conditions  precedent, and the
   underwriters will be  obligated to purchase all such Securities  if any are
   purchased.

     Securities  may be  sold  directly  by  the  Company  or  through  agents
   designated by the  Company from time to  time.  Each  Prospectus Supplement
   will set forth the name of any agent  involved in the offer or sale of  the
   Securities in respect of  which such Prospectus Supplement is  delivered as
   well  as any  commissions payable  by the  Company to  such agent.   Unless
   otherwise indicated in such  Prospectus Supplement, any such agent  will be
   acting on a best efforts basis for the period of its appointment.

     If  so indicated in a  Prospectus Supplement, the  Company will authorize
   agents,  underwriters or  dealers to  solicit offers  by  certain specified
   institutions to purchase the Securities offered thereby from the Company at
   the  public offering price set forth in such Prospectus Supplement pursuant
   to  delayed  delivery contracts  providing for  payment  and delivery  on a
   specified date  in the  future.   Such contracts will  be subject  to those
   conditions  set forth in such  Prospectus Supplement, which  will set forth
   the commission payable for solicitation of such contracts.

     Agents and  underwriters may  be entitled under  agreements entered  into
   with  the Company to indemnification  by the Company  against certain civil
   liabilities, including  liabilities under  the Securities  Act of  1933, as
   amended.


                                     EXPERTS

     The  financial  statements  and  the  financial  statement  schedules  of
   Northwest  Natural Gas Company incorporated in this Prospectus by reference
   from  the  Company's  Annual Report  on  Form 10-K,  have  been  audited by
   Deloitte & Touche, independent  auditors, as stated in their  report, which
   is  incorporated  herein by  reference, and  have  been so  incorporated in
   reliance  upon the  report  of such  firm, given  upon  their authority  as
   experts in accounting and auditing.

     With  respect  to the  unaudited interim  financial information  which is
   incorporated herein  by reference, Deloitte  & Touche  has applied  limited
   procedures in accordance with  professional standards for a review  of such
   information.  However, as stated in their reports included in the Company's
   Quarterly Reports on Form  10-Q and incorporated by reference  herein, they
   did not audit  and they do not express an opinion on that interim financial
   information.   Accordingly, the degree of reliance on their reports on such
   information should  be restricted  in light  of the  limited nature of  the
   review  procedures applied.    Deloitte  & Touche  is  not  subject to  the
   liability provisions  of  Section 11  of  the Securities  Act of  1933,  as
   amended,  for their reports on the  unaudited interim financial information
   because  such reports  are not  "reports" or a  "part" of  the registration
   statement  prepared or  certified by  an accountant  within the  meaning of
   Sections 7 and 11 of the Act.

     The statements made  as to matters  of law and  legal conclusions in  the
   documents  incorporated   in  this   Prospectus  by  reference   and  under
   "Description of the  New  Bonds"  and "Description of Common  Stock" herein
   and, if any, in  the accompanying Prospectus Supplement have  been reviewed
   by Bruce  B. Samson,  Esquire, Portland,  Oregon.   Mr.  Samson is  General
   Counsel of  the Company.  These statements and conclusions are set forth in
   reliance  upon the  opinion of Mr.  Samson given  upon his  authority as an
   expert.  As of March 31,  1994, Mr. Samson owned approximately 2,802 shares
   of the Company's common stock (including 1,009 shares through the Company's
   Retirement K Savings Plan) and  has been granted options to  purchase 8,000
   additional shares  at a price of  $24.875 and 2,000 additional  shares at a
   price  of $36.00, the  market prices  of the  shares on  the dates  of such
   grants.   Mr. Samson's shares,  including the underlying  shares subject to
   options granted  to him, have a current  fair market value of approximately
   $412,865.


                                     LEGALITY

     The legality of the Securities will be passed upon for the Company by Mr.
   Samson and by Reid  & Priest, New  York, New York.   Certain legal  matters
   will  be passed upon for the Underwriters  by Simpson Thacher & Bartlett (a
   partnership which includes professional  corporations), New York, New York.
   However, all matters pertaining  to titles, the lien and  enforceability of
   the Mortgage, franchises and all other matters of Oregon and Washington law
   will be passed upon only by Mr. Samson.

   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 reasonable 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 reasonable 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  has been met
   and a written  undertaking by such  director or officer  to repay such  ex-
   penses if it is ultimately determined that he or  she 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;

     (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 17.  UNDERTAKINGS.


            The undersigned registrant hereby undertakes:

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

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

            (ii)   To reflect  in the  prospectus any  facts or  events arising
   after the effective  date of the registration statement (or the most recent
   post-effective amendment thereof) which,  individually or in the aggregate,
   represent  a fundamental  change  in  the  information  set  forth  in  the
   registration statement;
     
            (iii)   To include  any material  information with  respect to  the
   plan of distribution not previously disclosed in the registration statement
   or any material change to such information in the registration statement;

            Provided, however, that  paragraphs (1)(i) and (1)(ii) do not apply
   if  the  registration  statement  is  on Form  S-3  or  Form  S-8,  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 this
   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 indemnification  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.


                                POWER OF ATTORNEY

             Each director  and/or officer  of the  registrant whose  signature
   appears  hereinafter hereby appoints Robert L. Ridgley, Bruce R. DeBolt and
   Robert  G.  Schuur,  the Agents  for  Service  named  in this  registration
   statement, and each  of them severally, as his  attorney-in-fact to sign in
   his name and behalf, in  any and all capacities  stated below, and to  file
   with  the  Securities and  Exchange  Commission,  any and  all  amendments,
   including  post-effective amendments,  to this registration  statement, and
   the  registrant hereby also  appoints each  such Agent  for Service  as its
   attorney-in-fact with like authority  to sign and file any  such amendments
   in its name and behalf.

             (a)  A registration statement with respect to the Securities
        has   been  prepared  by  the  Company  in  conformity  with  the
        requirements  of  the Securities  Act  of 1933,  as  amended (the

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

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

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

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

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

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

             (g)  The  Indenture and  the Securities have  been duly  and
        validly  authorized; and,  when  the Securities  shall have  been
        delivered  against  payment  therefor  as  provided  herein,  the
        Indenture and  the Securities  will be  legal, valid  and binding
        obligations of the Company,  enforceable in accordance with their
        terms, except as limited by bankruptcy, insolvency and other laws
        affecting  the enforcement  of mortgagees'  and other  creditors'
        rights, the Indenture will be qualified under the Trust Indenture
        Act, and the  Indenture and  the Securities will  conform to  the
        descriptions thereof contained in the Prospectus; and

             (h)  Other than as set forth in the Prospectus, there are no
        legal,  governmental  or  administrative proceedings  pending  to
        which the  Company is a  party or  of which any  property of  the
        Company is the subject, the  outcome of which, in the  opinion of
        the Company, would  singly or  in the aggregate  have a  material
        adverse effect on the business, property or financial position of
        the Company; and, to the best of the Company's knowledge, no such
        proceedings  are  threatened   or  contemplated  by  governmental
        authorities or threatened by others.
        
             2.   Purchase and  Sale.   Subject  to the  terms and  conditions
   herein         -----------------
   set  forth, the  Company agrees to  sell to  each of  you, and each  of you
   agrees,  severally and not  jointly, to purchase  from the  Company, at the
   Price  to  the Company  set forth  on the  first  page hereof  plus accrued
   interest,  if any, thereon from the Interest Commencement Date set forth on
   the first page hereof to the Time of Delivery (as hereinafter defined), the
   Securities  in  the amounts  set forth  opposite  your respective  names in
   Schedule I hereto.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        Statement  and the  Prospectus  (or any  amendment or  supplement
        thereto), except as may  otherwise be stated in  the Registration
        Statement  and  Prospectus   (or  any  amendment   or  supplement

        taken  as a whole, other than those reflected in the Registration
        Statement  or  the Prospectus  (or  any  amendment or  supplement
        thereto).

             (b)   At the Time of Delivery,  there shall be in full force
        and  effect orders of the Public Utility Commission of Oregon and

        authorizing  the issuance and sale of the Securities on the terms
        and  conditions herein  set  forth, and  containing no  provision
        unacceptable to you  by reason of the fact that  it is materially
        adverse  to the  Company (it  being understood  that no  order in
        effect  on  the  date   hereof  contains  any  such  unacceptable
        provision).
        
             (c)  At  the Time of Delivery, you  shall have received from
        Bruce B. Samson,  Esq., General  Counsel of the  Company, Reid  &
        Priest, of counsel to the Company, and Simpson Thacher & Bartlett

        counsel, opinions,  dated the Time of  Delivery, in substantially
        the form and substance prescribed in Exhibits A, B, and C hereto.

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

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

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

                  (iii)    On  the   basis  of  limited  procedures,  not
             constituting   an  examination   made  in   accordance  with
             generally accepted auditing  standards, including a  reading
             of the latest available  interim financial statements of the
             Company,  if any,  a  reading of  the  minute books  of  the
             Company since  December 31, 1993, inquiries  of officials of
             the Company responsible for financial and accounting matters
             and such other inquiries and  procedures as may be specified
             in such letter, nothing came to  their attention that caused
             them to believe that:

                  (A)(1)   any material  modifications should be  made to
             the  unaudited  condensed consolidated  financial statements
             incorporated by reference in  the Registration Statement for
             them to be in  conformity with generally accepted accounting
             principles,  or  (2)  the unaudited  condensed  consolidated
             financial  statements  incorporated  by  reference   in  the
             Registration  Statement  do not  comply with  the applicable
             accounting requirements of the Exchange Act as they apply to
             Form 10-Q and the related published rules and regulations; 

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

                  (C)   for  the  12-month period  for  which the  latest
             unaudited financial statements are available, there were any
             decreases, as  compared with the latest  12-month period for
             which financial statements are  incorporated by reference in
             the  Prospectus,  in  operating  revenues,  net  income  and
             earnings available for common stock, except in each case for
             decreases  which the  Registration Statement  discloses have
             occurred  or  may  occur,   which  were  occasioned  by  the
             declaration  of dividends  or  which are  described in  such
             letter; and

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

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

             (f)   All legal proceedings  to be taken  in connection with
        the  issuance and sale of the Securities shall be satisfactory in
        form and substance to your counsel.

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

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

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

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

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

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

             8.  Indemnifications.  (a)  The Company agrees to indemnify and
                 ----------------
   hold harmless each of  you and each person  who controls any of you  within
   the meaning of Section 15  of the Act against  any and all losses,  claims,
   damages  or liabilities, joint or several, to which they or any of them may
   become subject  under the Act,  the Exchange  Act or any  other statute  or
   common  law, and to reimburse each of  you and each such controlling person
   for  any  legal or  other expenses  (including,  to the  extent hereinafter
   provided,  reasonable counsel fees) incurred  by you or  them in connection
   with  investigating any such losses,  claims, damages or  liabilities or in
   connection  with defending  any actions,  insofar as  such losses,  claims,
   damages, liabilities, expenses or  actions arise out of  or are based  upon
   any  untrue  statement  or alleged  untrue  statement  of  a material  fact
   contained  in the  Registration  Statement  or  Prospectus  as  amended  or
   supplemented  (if any  amendments or  supplements thereto  shall have  been
   furnished)  or the omission or alleged omission to state therein a material
   fact  required to  be stated  therein or  necessary to make  the statements
   therein  not misleading;  provided, however,  that the  indemnity agreement
   contained in this subsection (a) shall not apply to any such losses, claims,
   damages,  liabilities, expenses or actions  arising out of,  or based upon,
   any such untrue statement or alleged untrue statement, or any such omission
   or  alleged omission,  if such statement  or omission was  made in reliance
   upon written information furnished to the Company by or on behalf of any of
   you  specifically for  use  in  connection  with  the  preparation  of  the
   Registration Statement, the  Prospectus or any  amendment or supplement  to
   either thereof or  arising out of or based upon  statements in or omissions
   from that part  of the  Registration Statement which  shall constitute  the
   Statements  of Eligibility  under the  Trust Indenture  Act of 1939  of the
   Trustees  under the  Indenture; and provided,  further, that  the indemnity
   agreement contained in this paragraph shall not inure to the benefit of any
   of  you (or of any  of your controlling persons) on  account of any losses,
   claims,  damages, liabilities, expenses or actions arising from the sale of
   any of  the Securities  to  any person  if a  copy of  the Prospectus,  as
   amended or  supplemented (if  any amendments or  supplements thereto  shall
   have  been furnished),  excluding  any document  incorporated by  reference
   therein, shall not have been sent or given to such person with or  prior to
   the written confirmation  of the sale involved, unless such  failure is the
   result of non-compliance  by the  Company with  Section 5(a)  hereof.   The
   indemnity  agreement of the Company contained  in this Section 8(a) and the
   representations and warranties of the Company contained in Section 1 hereof
   shall remain  operative and  in full  force and effect,  regardless of  any
   investigation made by or  on behalf of any  of you or any such  controlling
   person, and  shall survive the delivery  of the Securities.   The indemnity
   agreement of  the  Company contained  in  this  Section 8(a)  shall  be  in
   addition  to  any liability  which  the Company  may  otherwise have  to an
   indemnified party hereunder.

             (b)  Each  of  you,  severally,  agrees  to  indemnify  and  hold
   harmless the Company,  its directors, each of  its officers who shall  have
   signed  the Registration Statement and each person who controls the Company
   within the  meaning of Section  15 of the  Act against any and  all losses,
   claims, damages or liabilities, joint  or several, to which they or  any of
   them may  become subject  under  the Act,  the Exchange  Act  or any  other
   statute or common law, and to reimburse each of them for any legal or other
   expenses (including, to the extent hereinafter provided, reasonable counsel
   fees)  incurred by them in  connection with investigating  any such losses,
   claims,  damages or liabilities or in connection with defending any action,
   insofar as such  losses, claims, damages, liabilities,  expenses or actions
   arise  out of  or are  based upon  any untrue  statement or  alleged untrue
   statement of a  material fact  contained in the  Registration Statement  or
   Prospectus as  amended or  supplemented (if any  amendments or  supplements
   thereto shall have  been furnished) or the omission  or alleged omission to
   state therein a material fact required to be stated therein or necessary to
   make the statements therein  not misleading, if such statement  or omission
   was made in  reliance upon written information furnished to  the Company by
   or on  behalf of  any of you  specifically for use  in connection  with the
   preparation of the Registration Statement,  the Prospectus or any amendment
   or  supplement  to either  thereof.   Your respective  indemnity agreements
   contained  in this Section 8(b)  and the representations  and warranties of
   each of  you which shall have signed this Agreement contained in Section 12
   hereof shall remain operative  and in full force and effect,  regardless of
   any investigation made by or on behalf of the Company or any such director,
   officer  or controlling  person,  and shall  survive  the delivery  of  the
   Securities.   The  indemnity agreement  of each  of  you contained  in this
   Section 8(b) shall be in addition  to any liability which you may otherwise
   have to an indemnified party hereunder.

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

             (d)  In order to  provide for just and equitable  contribution in
   circumstances in which the indemnification provided for in Sections 8(a) or
   (b) hereof shall be  due in accordance  with its terms  but for any  reason
   shall  be  unavailable  or  insufficient  to  hold  any  indemnified  party
   thereunder  harmless  in   respect  of  any  losses,   claims,  damages  or
   liabilities  referred to  therein, the  Company and  each of  you severally
   shall  contribute to the aggregate losses,  claims, damages and liabilities
   to which the Company and one or more  of you may be subject, as a result of
   such  losses,  claims, damages  or liabilities,  in  such proportion  as is
   appropriate to  reflect the relative fault  of the Company on  the one hand
   and each of you on the other in connection with the statements or omissions
   which resulted  in such losses, claims,  damages or liabilities  as well as
   any other  equitable considerations  including, with  respect  only to  any
   losses,  claims, damages of liabilities referred to in Section 8(a) hereof,
   relative  benefit.   Relative fault  shall be  determined by  reference to,
   among other things,  whether the untrue  or alleged untrue  statement of  a
   material fact  or the omission or alleged omission to state a material fact
   relates to information supplied by the Company, on the one hand, or you, on
   the  other, and  the  parties' relative  intent,  knowledge and  access  to
   information  and opportunity  to  correct  or  prevent  such  statement  or
   omission.   The relative benefits received  by the Company on  the one hand
   and you on the  other shall be deemed to  be in the same proportion  as the
   total  net proceeds from the  offering of the  Securities (before deducting
   expenses)  received by the Company bear to the total underwriting discounts
   and commissions  received  by  you with  respect  to the  offering  of  the
   Securities.  Notwithstanding the foregoing,  no person guilty of fraudulent
   misrepresentation (within the meaning of Section 11(f) of the Act) shall be
   entitled  to  contribution from  any  person  who was  not  guilty  of such
   fraudulent misrepresentation.  The Company and you agree that  it would not
   be just and equitable  if contribution pursuant  to this Section 8(d)  were
   determined  (i) by any method of allocation  which does not take account of
   the equitable considerations  referred to  above in this  Section 8(d),  or
   (ii)  with respect  only  to any  losses,  claims, damages  or  liabilities
   referred to in  Section 8(a) hereof,  by pro rata  allocation (even if  you
   were treated as one  entity for such purpose).  The  amount paid or payable
   by a  party entitled to  contribution as  a result of  the losses,  claims,
   damages  or liabilities  referred to  above in  this Section 8(d)  shall be
   deemed to include  any legal or other expenses reasonably  incurred by such
   party  in connection  with investigating  or defending  any such  action or
   claim.    For purposes  of  this Section  8(d),  each person,  if  any, who
   controls any of  you within the meaning of Section 15 of the Act shall have
   the same rights to contribution  as you, and each director, officer  of the
   Company who shall  have signed  the Registration Statement  and person  who
   controls the Company within the meaning of Section 15 of the Act shall have
   the same rights to contribution  as the Company, subject, in each  case, to
   the fourth sentence of this Section 8(d).

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

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

   within 24  hours, and if  to you,  shall be sufficient  in all  respects if
   delivered or sent by registered mail either to you at your address given on
   the last page hereof or, if this Agreement shall have been executed on your
   behalf  by  a representative  as provided  in  Section 13  hereof,  to your

   Company shall  be  sufficient in  all  respects  if delivered  or  sent  by

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

                                                ____________


   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the Underwriting Agreement, dated
   ___________ (the "Agreement"), between the Company and you of
   ________________ in principal amount of First Mortgage Bonds, _______
   Series due ____ (the "Securities"), issued under the Company's Mortgage and
   Deed of Trust, dated as of July 1, 1946, as supplemented by _________
   indentures supplemental thereto, the latest dated as of _____________, to
   Bankers Trust Company and Stanley Burg, as Trustees (such Mortgage, as so
   supplemented, being hereinafter called the "Indenture"), please be advised
   that, as General Counsel of the Company, I have participated in the
   preparation of or reviewed (a) the registration statement relating to the
   Securities filed by the Company with the Securities and Exchange Commission
   (the "Commission") under the Securities Act of 1933 (the "Securities Act")
   (such registration statement, as it became effective, being hereinafter
   called the "Registration Statement" and the prospectus constituting a part
   of the Registration Statement, in the form (i) completed or supplemented,
   (ii) dated ______________, and (iii) filed with the Commission pursuant to
   Rule 424(b) under the Securities Act, including the documents incorporated
   therein by reference pursuant to Item 12 of Form S-3 on the date hereof,
   being hereinafter called the "Prospectus"); (b) the proceedings before the
   Public Utility Commission of Oregon and the Washington Utilities and
   Transportation Commission for authority to issue and sell the Securities
   and the order or orders entered by those Commissions in respect thereto;
   (c) the Restated Articles of Incorporation of the Company, its Bylaws and
   the actions taken by its Board of Directors and the Executive Committee
   thereof authorizing the issuance and sale of the Securities; (d) the
   Indenture; and (e) such other matters as I have deemed to be necessary to
   enable me to render the opinions herein expressed.  I have not examined the
   Securities, except a specimen thereof, and have relied upon a certificate
   of Bankers Trust Company as to the authentication thereof.

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

             I am of the opinion that:

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

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

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

             4.   The Company has good and sufficient title to all the
        properties described in, and as subject to the lien of, the Indenture
        and now owned by it subject only to excepted encumbrances as defined
        in the Indenture, and to minor defects and irregularities customarily
        found in properties of like size and character, which do not
        materially impair the use of the property affected thereby in the
        operation of the business of the Company; the description in the
        Indenture of said properties is adequate to constitute the Indenture a
        lien thereon; and the Indenture constitutes a valid, direct first
        mortgage lien on such properties, which include substantially all of
        the permanent physical properties and franchises of the Company (other
        than those expressly excepted), subject only to the exceptions
        enumerated above in this paragraph.

             5.   The Securities have been duly and validly authorized and,
        when the Securities shall have been delivered against payment therefor
        as provided in the Agreement, they will have been duly and validly
        issued and will be legal, valid and binding obligations of the Company
        enforceable in accordance with their terms, except as limited by
        bankruptcy, insolvency, or other laws affecting the enforcement of
        mortgagees' and other creditors' rights and will be entitled to the
        benefit of the security afforded by the Indenture.

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

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

             8.   The Public Utility Commission of Oregon and the Washington
        Utilities and Transportation Commission have issued orders authorizing
        the issuance and sale by the Company of the Securities; the issuance
        and sale of the Securities in accordance with the Agreement are in
        conformity with the terms of such orders; and no further approval,
        authorization, consent or other order of any public board or body
        (other than in connection or in compliance with the provisions of the
        securities or blue sky laws of any jurisdiction) is legally required
        for the issuance and sale of the Securities on the terms and
        conditions set forth in the Agreement.

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

             10.  There are no legal, governmental or administrative
        proceedings pending to which the Company is a party or of which any
        property of the Company is the subject, other than as set forth in the
        Prospectus and other than proceedings incident to the kind of business
        conducted by the Company, the outcome of which would singly or in the
        aggregate have a materially adverse effect on the financial position,
        stockholders' equity or results of operations of the Company; and, to
        the best of my knowledge, no such proceedings are threatened or
        contemplated by governmental authorities or threatened by others.

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

             12.  The consummation of the transactions contemplated in the
        Agreement and the fulfillment of the terms thereof will not result in
        a breach of any of the terms or provisions of, or constitute a default
        under, any statute, indenture, mortgage, deed of trust or other
        agreement or instrument known to me to which the Company is a party or
        by which it is bound or to which any of the property of the Company is
        subject, or the Restated Articles of Incorporation or Bylaws of the
        Company or any order, rule or regulation of any court or other
        governmental body having jurisdiction over the Company or any of its
        property.

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

             I am a member of the bars of the States of Oregon and Washington
   and do not hold myself out as expert on the laws of any other state.
   
             I have read the opinions of even date herewith rendered to you by
   Reid & Priest and Simpson Thacher & Bartlett, and I concur in the
   conclusions therein expressed, insofar as such conclusions involve
   questions of Oregon and Washington law.

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

                                      Very truly yours,



                                      BRUCE B. SAMSON

                                                                EXHIBIT B

   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the Underwriting Agreement, dated
   ______________ (the "Agreement"), between the Company and you of
   ______________ in principal amount of First Mortgage Bonds, ______ Series
   due ____ (the "Securities"), issued under the Company's Mortgage and Deed
   of Trust, dated as of July 1, 1946, as supplemented by __________
   indentures supplemental thereto, the latest dated as of ____________, to
   Bankers Trust Company and Stanley Burg, as Trustees (such Mortgage, as so
   supplemented, being hereinafter called the "Indenture"), please be advised
   that, as counsel to the Company, we have participated in the preparation of
   or reviewed (a) the registration statement relating to the Securities filed
   by the Company with the Securities and Exchange Commission (the
   "Commission") under the Securities Act of 1933 (the "Securities Act") (such
   registration statement, as it became effective, being hereinafter called
   the "Registration Statement" and the prospectus constituting a part of the
   Registration Statement, in the form (i) completed or supplemented, (ii)
   dated ______________ and (iii) filed with the Commission pursuant to Rule
   424(b) under the Securities Act, including the documents incorporated
   therein by reference pursuant to Item 12 of Form S-3 on the date hereof,
   being hereinafter called the "Prospectus"); (b) the proceedings before the
   Public Utility Commission of Oregon and the Washington Utilities and
   Transportation Commission for authority to issue and sell the Securities
   and the order or orders entered by the Commissions in respect thereto; (c)
   the Restated Articles of Incorporation of the Company, its Bylaws and the
   actions taken by its Board of Directors and the Executive Committee thereof
   authorizing the issuance and sale of the Securities; (d) the Indenture; and
   (e) such other matters as we have deemed to be necessary to enable us to
   render the opinions herein expressed.  We have not examined the Securities,
   except a specimen thereof, and have relied upon a certificate of Bankers
   Trust Company as to the authentication thereof.

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

             Based upon the foregoing, we are of the opinion that:

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

             2.   The Indenture has been duly and validly authorized by all
        necessary corporate action, has been duly and validly executed and
        delivered, has been duly qualified under the Trust Indenture Act of
        1939, as amended, and is a valid and binding instrument enforceable in
        accordance with its terms, except as limited by bankruptcy, insolvency
        or other laws affecting enforcement of mortgagees' and other
        creditors' rights. 

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

             4.   The Indenture and the Securities conform as to legal matters
        with the descriptions thereof contained in the Prospectus. 

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

             6.   The Registration Statement, as of its effective date, and
        the Prospectus, as of the time it was filed with the Commission
        pursuant to Rule 424(b) complied as to form in all material respects
        with the requirements of the Securities Act, the Trust Indenture Act
        of 1939, as amended, and the rules and regulations thereunder, and the
        documents incorporated by reference in the Prospectus on the date
        hereof complied as to form in all material respects with the
        requirements of the Securities Exchange Act of 1934 and the rules and
        regulations thereunder at the respective times at which such documents
        were filed with the Commission, except that we express no opinion with
        respect to the financial statements and other financial data contained
        in the Registration Statement or the Prospectus. 

             7.   The Public Utility Commission of Oregon and the Washington
        Utilities and Transportation Commission have issued orders authorizing
        the issuance and sale by the Company of the Securities; the issuance
        and sale of the Securities are in conformity with the terms of such
        orders; and no further approval, authorization, consent or other order
        of any public board or body (other than in connection or in compliance
        with the provisions of the securities or blue sky laws of any
        jurisdiction) is legally required for the issuance and sale of the
        Securities on the terms and conditions set forth in the Agreement.

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

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

             We are members of the New York Bar and do not hold ourselves out
   as experts on the laws of the States of Oregon and Washington.  As to all
   matters of Oregon and Washington law (including titles to property and
   franchises and the lien of the Indenture, upon which we do not pass), we
   have relied, with your consent, upon an opinion addressed to you of even
   date herewith of Bruce B. Samson, Esq., General Counsel of the Company,
   whom we believe to be qualified to pass upon such matters.
   
             This opinion may be relied upon by you only in connection with
   the issuance and sale of the Securities.  This opinion may not be relied
   upon by you for any other purpose, or relied upon by any other person,
   without, in each instance, our prior written consent.

                                         Very truly yours,

   [Representatives]

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

   [Address]


   Dear Sirs:

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

             We have examined the Registration Statement on Form S-3 (File No.
   33-______) filed by the Company under the Securities Act of 1933, as
   amended (the "Act"), as it became effective under the Act (the
   "Registration Statement"); the Company's prospectus dated ______, 1994, as
   supplemented by the prospectus supplement dated _____, 199_  (the
   "Prospectus"), filed by the Company pursuant to Rule 424(b) of the rules
   and regulations of the Securities and Exchange Commission (the
   "Commission") under the Act, which pursuant to Form S-3 incorporates by
   reference or is deemed to incorporate by reference the Annual Report on
   Form 10-K of the Company for the fiscal year ended December 31, 199_, and
   ____________ (the "Exchange Act Documents"), each as filed under the
   Securities Exchange Act of 1934, as amended (the "Exchange Act"); and the
   Mortgage.  In addition, we have examined, and have relied as to matters of
   fact upon, the documents delivered to you at the closing (except the
   Securities, of which we have examined a specimen), and upon originals or
   copies, certified or otherwise identified to our satisfaction, of such
   corporate records, agreements, documents and other instruments and such
   certificates or comparable documents or oral statements of public officials
   and of officers and representatives of the Company, and have made such
   other and further investigations, as we have deemed relevant and necessary
   as a basis for the opinions hereinafter set forth.

             In such examination, we have assumed the genuineness of all
   signatures, the legal capacity of natural persons, the authenticity of all
   documents submitted to us as originals, the conformity to original
   documents of all documents submitted to us as certified or photostatic
   copies, and the authenticity of the originals of such latter documents.

             Based upon the foregoing, and subject to the qualifications and
   limitations stated herein, we hereby advise you that in our opinion:  

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

             2.  The Mortgage has been duly authorized, executed and delivered
        by the Company and duly qualified under the Trust Indenture Act of
        1939, as amended (the "Trust Indenture Act"), and, assuming due
        authorization, execution and delivery thereof by the Trustees,
        constitutes a valid and legally binding instrument of the Company
        enforceable against the Company in accordance with its terms.

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

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

             6.  The Public Utility Commission of Oregon and the Washington
        Utilities and Transportation Commission have issued orders authorizing
        the issuance and sale by the Company of the Securities; the issuance
        and sale of the Securities in accordance with the Underwriting
        Agreement are in conformity with the terms of such orders; and no
        other approval or consent of any Federal, Oregon or Washington
        governmental body (except for any approval or consent under state
        "blue sky" or securities laws, as to which we express no opinion) is
        required for the issuance and sale of the Securities to you on the
        terms and conditions set forth in the Underwriting Agreement. 

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

             All legal proceedings taken by the Company in connection with the
   authorization and delivery of the Securities, and the legal opinions dated
   the date hereof, rendered to you by Bruce B. Samson, Esq., General Counsel
   of the Company, and Reid & Priest, counsel for the Company, are in form
   satisfactory to us.  Insofar as the opinions expressed herein relate to or
   are dependent upon matters governed by the laws of the States of Oregon
   and/or Washington, we have relied upon the aforesaid opinion of Bruce B.
   Samson, Esq.  We express no opinion on matters relating to titles to
   property, franchises or the lien of the Mortgage.

             We have not independently verified the accuracy, completeness or
   fairness of the statements made or included in the Registration Statement,
   the Prospectus or the Exchange Act Documents and take no responsibility
   therefor, except as and to the extent set forth in paragraph 4 above.  In
   the course of the preparation by the Company of the Registration Statement
   and the Prospectus (excluding the Exchange Act Documents), we participated
   in conferences with certain officers and employees of the Company, with
   representatives of Deloitte & Touche and with counsel to the Company.  We
   did not prepare the Exchange Act Documents or review the Exchange Act
   Documents prior to their filing with the Commission.  Based upon our
   examination of the Registration Statement, the Prospectus and the Exchange
   Act Documents, our investigations made in connection with the preparation
   of the Registration Statement and the Prospectus (excluding the Exchange
   Act Documents) and our participation in the conferences referred to above,
   (i) we are of the opinion that the Registration Statement, as of its
   effective date, and the Prospectus, as of ____________, 199__, complied as
   to form in all material respects with the requirements of the Act, the
   Trust Indenture Act and the applicable rules and regulations of the
   Commission thereunder and that the Exchange Act Documents complied as to
   form when filed in all material respects with the requirements of the
   Exchange Act and the applicable rules and regulations of the Commission
   thereunder, except that in each case we express no opinion with respect to
   the financial statements or other financial or statistical data contained
   or incorporated by reference in the Registration Statement, the Prospectus
   or the Exchange Act Documents, and (ii) we have no reason to believe that
   the Registration Statement [, as of its effective date (including the
   Exchange Act Documents on file with the Commission on such effective date,]
   [, as of the date of filing of the Annual Report on Form 10-K of the
   Company for the fiscal year ended December 31, 199_ (including such Annual
   Report for the fiscal year ended December 31, 199_),] contained any untrue
   statement of a material fact or omitted to state any material fact required
   to be stated therein or necessary in order to make the statements therein
   not misleading or that the Prospectus (including the Exchange Act
   Documents) contains any untrue statement of a material fact or omits to
   state any material fact necessary in order to make the statements therein,
   in the light of the circumstances under which they were made, not
   misleading, except that in each case we express no belief with respect to
   the financial statements or other financial or statistical data contained
   or incorporated by reference in the Registration Statement, the Prospectus
   or the Exchange Act Documents.

             We are members of the Bar of the State of New York and we do not
   express any opinion herein concerning any law other than the law of the
   State of New York and the Federal law of the United States and, to the
   extent set forth herein and in reliance solely upon the aforesaid opinion
   of Bruce B. Samson, Esq., the laws of the States of Oregon and Washington.

             This opinion is rendered to you in connection with the above
   described transactions.  This opinion may not be relied upon by you for any
   other purpose, or relied upon by, or furnished to, any other person, firm
   or corporation without our prior written consent.

                                 Very truly yours,


   








                                                                  EXHIBIT 1(b)

                              UNDERWRITING AGREEMENT
                              ----------------------


                          NORTHWEST NATURAL GAS COMPANY

                                   Common Stock


                     Price to the Company:  $_____ per Share


                                                __________ __, 1994


   To the Underwriters named in Schedule I hereto

   Dear Sirs:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        of the fact that it is materially adverse to the Company (it being

        such unacceptable provision).

             (c)  At the Time of Delivery, you shall have received from Bruce
        B. Samson, Esq., General Counsel of the Company, Reid & Priest, of

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

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

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

                  (iii)  On the basis of limited procedures, not constituting
             an examination made in accordance with generally accepted
             auditing standards, including a reading of the latest available
             interim financial statements of the Company, if any, a reading of
             the minute books of the Company since December 31, 1993,
             inquiries of officials of the Company responsible for financial
             and accounting matters and such other inquiries and procedures as
             may be specified in such letter, nothing came to their attention
             that caused them to believe that:

                       (A)(1) any material modifications should be made to the
                  unaudited condensed consolidated financial statements
                  incorporated by reference in the Registration Statement for
                  them to be in conformity with generally accepted accounting
                  principles, or (2) the unaudited condensed consolidated
                  financial statements incorporated by reference in the
                  Registration Statement do not comply with the applicable
                  accounting requirements of the Exchange Act as they apply to
                  Form 10-Q and the related published rules and regulations; 

                       (B)  at the date of the latest available interim
                  balance sheet of the Company and at a subsequent specified
                  date not more than five days prior to the Time of Delivery,
                  there has been any change in the capital stock (except for
                  (I) shares of the Company's Common Stock issued under the
                  Company's Dividend Reinvestment Plan, 1985 Stock Option Plan
                  or Employee Stock Purchase Plan, (II) shares of Common Stock
                  issued upon the conversion of shares of the Company's
                  Convertible Preference Stock or Convertible Debentures, and

                  pursuant to or in anticipation of sinking and purchase funds
                  with respect to the Company's Preferred Stock), or any
                  increase in the long-term debt of the Company, or any
                  decrease in net assets, in each case as compared with
                  amounts shown in the balance sheet as of the date of the
                  latest financial statements incorporated by reference in the
                  Registration Statement, except in each case for changes,
                  increases or decreases which the Registration Statement
                  discloses have occurred or may occur, which were occasioned
                  by the declaration of dividends or which are described in
                  such letter; or

                       (C)  for the 12-month period for which the latest
                  unaudited financial statements are available, there were any
                  decreases, as compared with the latest 12-month period for
                  which financial statements are incorporated by reference in
                  the Prospectus, in operating revenues, net income and
                  earnings available for common stock, except in each case for
                  decreases which the Registration Statement discloses have
                  occurred or may occur, which were occasioned by the
                  declaration of dividends or which are described in such
                  letter; and

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

             (e)  At the Time of Delivery, you shall have received a
        certificate, dated the Time of Delivery and signed by an executive

        post-effective amendment to the Registration Statement shall have been

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

             (f)  All legal proceedings to be taken in connection with the
        issuance and sale of the Securities shall be satisfactory in form and
        substance to your counsel.

             (g)  There shall not have been any announcement by any
        "nationally recognized statistical rating organization", as defined
        for purposes of Rule 436(g) under the Act, that (i) it is downgrading
        its rating assigned to any debt securities or preferred or preference
        stock of the Company, or (ii) it is reviewing its rating assigned to,
        or placing on credit watch, any debt securities or preferred or
        preference stock of the Company with a view to downgrading, or with
        negative implications, or direction not determined.  

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

        the Securities.

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

        the fact that it is materially adverse to the Company (it being
        understood that no order in effect on the date hereof contains any
        such unacceptable provision).
        
        In case any of the conditions specified above in this Section 7
   shall not have been fulfilled at the Time of Delivery or the Option Shares
   Time of Delivery, as the case may be, this Agreement may be terminated by
   the Company, upon notice thereof to you.  Any such termination shall be
   without liability of any party to any other party, except as otherwise
   provided in Section 5 hereof.

             8.  Indemnifications.
                 ----------------

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

             (b)  Each of you, severally, agrees to indemnify and hold
        harmless the Company, its directors, each of its officers who shall
        have signed the Registration Statement and each person who controls
        the Company within the meaning of Section 15 of the Act against any
        and all losses, claims, damages or liabilities, joint or several, to
        which they or any of them may become subject under the Act, the
        Exchange Act or any other statute or common law, and to reimburse each
        of them for any legal or other expenses (including, to the extent
        hereinafter provided, reasonable counsel fees) incurred by them in
        connection with investigating any such losses, claims, damages or
        liabilities or in connection with defending any action, insofar as
        such losses, claims, damages, liabilities, expenses or actions arise
        out of or are based upon any untrue statement or alleged untrue
        statement of a material fact contained in the Registration Statement
        or Prospectus as amended or supplemented (if any amendments or sup-
        plements thereto shall have been furnished) or the omission or alleged
        omission to state therein a material fact required to be stated
        therein or necessary to make the statements therein not misleading, if
        such statement or omission was made in reliance upon written
        information furnished to the Company by or on behalf of any of you
        specifically for use in connection with the preparation of the
        Registration Statement, the Prospectus or any amendment or supplement
        to either thereof.  Your respective indemnity agreements contained in
        this Section 8(b) and the representations and warranties of each of
        you which shall have signed this Agreement contained in Section 12
        hereof shall remain operative and in full force and effect, regardless
        of any investigation made by or on behalf of the Company or any such
        director, officer or controlling person, and shall survive the
        delivery of the Securities.  The indemnity agreement of each of you
        contained in this Section 8(b) shall be in addition to any liability
        which you may otherwise have to an indemnified party hereunder.

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

             (d)  In order to provide for just and equitable contribution in
        circumstances in which the indemnification provided for in Sections
        8(a) or (b) hereof shall be due in accordance with its terms but for
        any reason shall be unavailable or insufficient to hold any
        indemnified party thereunder harmless in respect of any losses,
        claims, damages or liabilities referred to therein, the Company and
        each of you severally shall contribute to the aggregate losses,
        claims, damages and liabilities to which the Company and one or more
        of you may be subject, as a result of such losses, claims, damages or
        liabilities, in such proportion as is appropriate to reflect the
        relative fault of the Company on the one hand and each of you on the
        other in connection with the statements or omissions which resulted in
        such losses, claims, damages or liabilities as well as any other
        equitable considerations, including, with respect only to any losses,
        claims, damages or liabilities referred to in Section 8(a) hereof,
        relative benefit.  Relative fault shall be determined by reference to,
        among other things, whether the untrue or alleged untrue statement of
        a material fact or the omission or alleged omission to state a
        material fact relates to information supplied by the Company, on the
        one hand, or you, on the other, and the parties' relative intent,
        knowledge and access to information and opportunity to correct or
        prevent such statement or omission.  The relative benefits received by
        the Company on the one hand and you on the other shall be deemed to be
        in the same proportion as the total net proceeds from the offering of
        the Securities (before deducting expenses) received by the Company
        bear to the total underwriting discounts and commissions received by
        you with respect to the offering of the Securities.  Notwithstanding
        the foregoing, no person guilty of fraudulent misrepresentation
        (within the meaning of Section 11(f) of the Act) shall be entitled to
        contribution from any person who was not guilty of such fraudulent
        misrepresentation.  The Company and you agree that it would not be
        just and equitable if contribution pursuant to this Section 8(d) were
        determined (i) by any method of allocation which does not take account
        of the equitable considerations referred to above in this Section
        8(d), or (ii) with respect only to any losses, claims, damages or
        liabilities referred to in Section 8(a) hereof, by pro rata allocation
        (even if you were treated as one entity for such purpose).  The amount
        paid or payable by a party entitled to contribution as a result of the
        losses, claims, damages or liabilities referred to above in this
        Section 8(d) shall be deemed to include any legal or other expenses
        reasonably incurred by such party in connection with investigating or
        defending any such action or claim.  For purposes of this Section
        8(d), each person, if any, who controls any of you within the meaning
        of Section 15 of the Act shall have the same rights to contribution as
        you, and each director and officer of the Company who shall have
        signed the Registration Statement and each person, if any, who
        controls the Company within the meaning of Section 15 of the Act shall
        have the same rights to contribution as the Company, subject, in each
        case, to the fourth sentence of this Section 8(d).

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

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

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

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

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

             12.  Representations and Warranties of Representatives of the
                  --------------------------------------------------------
   Underwriters.  Each of the undersigned, if any, which has signed this
   ------------
   Agreement as representative of the several Underwriters represents and
   warrants to the Company that it has full power and authority (a) to enter
   into this Agreement on behalf of each of the Underwriters listed in

   the performance of this Agreement.  In all dealings hereunder, the Company
   shall be entitled to act and rely upon any statement, request, notice or
   agreement on behalf of all of you made or given either by all of such
   undersigned representatives jointly or by any of such undersigned
   representatives individually.

             13.  Miscellaneous.
                  -------------

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

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

             (c)  This Agreement may be executed by any one or more of the
        parties hereto in any number of counterparts, each of which shall be
        deemed to be an original, but all such counterparts shall together
        constitute one and the same instrument.

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

                                           _____________ __, 1994




   [UNDERWRITERS]


   Dear Sirs:

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

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

             Based upon the foregoing, I am of the opinion that:
             
             1.  The Company is a validly organized and existing corporation
        in good standing under the laws of the State of Oregon, is qualified
        to do business and is in good standing in the State of Washington, and
        has power (corporate and other) to own its properties and conduct its
        business as described in the Prospectus.

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

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

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

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

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

             7.  The Public Utility Commission of Oregon and the Washington
        Utilities and Transportation Commission have issued orders authorizing
        the issuance and sale by the Company of the Securities; the issuance
        and sale of the Securities in accordance with the Agreement are in
        conformity with the terms of such orders; and no further approval,
        authorization, consent or other order of any public board or body
        (other than in connection or in compliance with the provisions of the
        securities or blue sky laws of any jurisdiction) is legally required
        for the issuance and sale of the Securities on the terms and
        conditions set forth in the Agreement.

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

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

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

             11.  The consummation of the transactions contemplated in the
        Agreement and the fulfillment of the terms thereof will not result in
        a breach of any of the terms or provisions of, or constitute a default
        under, any statute, indenture, mortgage, deed of trust or other
        agreement or instrument known to me to which the Company is a party or
        by which it is bound or to which any of the property of the Company is
        subject, or the Restated Articles of Incorporation or Bylaws of the
        Company or any order, rule or regulation of any court or other
        governmental body having jurisdiction over the Company or any of its
        property.

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

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

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

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

                                                                             
                                             
   
                                           Very truly yours,


                                           BRUCE B. SAMSON

                                 [Reid & Priest]



                                           ___________ __, 1994



   [UNDERWRITERS]


   Dear Sirs:

             With reference to the issuance and sale by Northwest Natural Gas
   Company (the "Company") pursuant to the  Underwriting  Agreement, dated
   _________ __, 1994 (the "Agreement"), between the Company and you of
   ___________ shares of the Company's Common Stock (the "Securities"), please
   be advised that, as counsel to the Company, we have participated in the
   preparation of or reviewed (a) the registration statement relating to the
   Securities filed by the Company with the Securities and Exchange Commission
   (the "Commission") under the Securities Act of 1933 (the "Securities Act")
   (such registration statement, as it became effective, being hereinafter
   called the "Registration Statement" and the prospectus constituting a part
   of the Registration Statement, in the form (i) completed or supplemented,
   (ii) dated _____________ __, 1994 and (iii) filed with the Commission
   pursuant to Rule 424(b) under the Securities Act, including the documents
   incorporated therein by reference pursuant to Item 12 of Form S-3 on the
   date hereof, being hereinafter called the "Prospectus"); (b) the
   proceedings before the Public Utility Commission of Oregon and the
   Washington Utilities and Transportation Commission for authority to issue
   and sell the Securities and the order or orders entered by the Commissions
   in respect thereto; (c) the Restated Articles of Incorporation of the Com-
   pany, its Bylaws and the actions taken by its Board of Directors and the
   Executive Committee thereof authorizing the issuance and sale of the
   Securities; (d) and such other matters as we have deemed to be necessary to
   enable us to render the opinions herein expressed.  We have not examined
   the Securities, except a specimen thereof, and have relied upon a certifi-
   cate of the transfer agent and the registrar for the Securities as to the
   issuance, registration and countersignature thereof.
   
             In our examination of the documents referred to above, we have
   assumed the authenticity of all such documents submitted to us as
   originals, the genuineness of all signatures, the due authority of the
   persons executing such documents and the conformity to the originals of all
   documents submitted to us as copies.  

             Based upon the foregoing, we are of the opinion that:

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

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

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

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

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

             6.   The Registration Statement, as of its effective date, and
        the Prospectus, as of the time it was filed with the Commission
        pursuant to Rule 424(b), complied as to form in all material respects
        with the requirements of the Securities Act, and the rules and
        regulations thereunder, and the documents incorporated by reference in
        the Prospectus on the date hereof complied as to form in all material
        respects with the requirements of the Securities Exchange Act of 1934
        and the rules and regulations thereunder at the respective times at
        which such documents were filed with the Commission, except that, in
        each case, we express no opinion with respect to the financial
        statements and other financial data contained in the Registration
        Statement or the Prospectus.
    
             7.   The Public Utility Commission of Oregon and the Washington
        Utilities and Transportation Commission have issued orders authorizing
        the issuance and sale by the Company of the Securities; the issuance
        and sale of the Securities in accordance with the Agreement are in
        conformity with the terms of such orders; and no further approval,
        authorization, consent or other order of any public board or body
        (other than in connection or in compliance with the provisions of the
        securities or blue sky laws of any jurisdiction) is legally required
        for the issuance and sale of the Securities on the terms and
        conditions set forth in the Agreement.

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

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

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

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

                                           Very truly yours,


                                           REID & PRIEST

   [Representatives]

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

   [Address]


   Dear Sirs:

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

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

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

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

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

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

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

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

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

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

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

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

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

             In such examination, we have assumed the genuineness of all

   signatures, the legal capacity of natural persons, the authenticity of all

   documents submitted to us as originals, the conformity to original

   documents of all documents submitted to us as certified or photostatic

   copies, and the authenticity of the originals of such latter documents.

             Based upon the foregoing, and subject to the qualifications and

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

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

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

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

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

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

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

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

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

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

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

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

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

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

   
             We have not independently verified the accuracy, completeness or

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

   the Prospectus or the Exchange Act Documents and take no responsibility

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

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

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

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

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

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

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

   examination of the Registration Statement, the Prospectus and the Exchange

   Act Documents, our investigations made in connection with the preparation

   of the Registration Statement and the Prospectus (excluding the Exchange

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

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

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

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

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

   or incorporated by reference in the Registration Statement, the Prospectus

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

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

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

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

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

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

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

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

   not misleading or that the Prospectus (including the Exchange Act

   Documents) contains any untrue statement of a material fact or omits to

   state any material fact necessary in order to make the statements therein,

   in the light of the circumstances under which they were made, not

   misleading, except that in each case we express no belief with respect to

   the financial statements or other financial or statistical data contained

   or incorporated by reference in the Registration Statement, the Prospectus

   or the Exchange Act Documents.

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

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

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

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

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

             This opinion is rendered to you in connection with the above

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

   or corporation without our prior written consent.

                                 Very truly yours,

   situated; and

          WHEREAS the Company now desires to create a new series  of bonds and
   (pursuant  to the provisions of Section 120 of  the Mortgage) to add to its

   capacity  to  hold  the same  for  the purposes  hereof)  to  Bankers Trust
   Company, as Trustees, and their successors and assigns forever.

          IN  TRUST  NEVERTHELESS, for  the same  purposes  and upon  the same

          AND  IT IS  HEREBY COVENANTED  by the  Company that  all the  terms,
   conditions, provisos,  covenants and provisions contained  in the Mortgage,

   beneficiaries  of  the trust  with respect  to  said property,  and  to the
   Trustees and their successors in the trust, in the same manner and with the
   same effect as  if the said property had  been owned by the Company  at the
   time of  the execution of  the Mortgage, and  had been specifically  and at
   length described in and conveyed to said Trustees by the Mortgage as a part
   of the property therein stated to be conveyed.

          The  Company further covenants and  agrees to and  with the Trustees
   and their successors in said trust under the Mortgage, as follows:


                                    ARTICLE  I.

                          Twenty-First Series of Bonds.

          SECTION 1.0.1.      There shall  be  a series  of  bonds  designated
   "Secured  Medium-Term Notes, Series B" (herein sometimes referred to as the
   "Twenty-first Series"), each of which shall also bear the descriptive title
   "First Mortgage Bond", and the form thereof,  which shall be established by
   Resolution of the Board of Directors of the Company, shall contain suitable
   provisions  with respect  to  the matters  hereinafter  in this  Article  I
   specified.  Bonds  of the Twenty-first Series shall be  issued from time to
   time as fully  registered bonds  in denominations of  One Thousand  Dollars
   and, at  the option of  the Company,  in any multiple  or multiples  of One
   Thousand Dollars  (the  exercise of  such  option to  be evidenced  by  the
   execution and delivery thereof); each bond of the Twenty-first Series shall
   mature  on such date, shall bear interest  at such rate or rates (which may
   be either fixed  or variable) and have such other  terms and provisions not
   inconsistent with the  Mortgage as the Board of Directors  may determine in
   accordance  with a Resolution filed with the Corporate Trustee referring to
   this Twentieth Supplemental Indenture; interest on each bond of the Twenty-
   first Series which bears interest at either a fixed rate or a variable rate
   shall be payable on the dates which shall  be established prior to the date
   of first authentication  of such  bond and set  forth in  such bond and  at
   maturity (each an  interest payment date).   Notwithstanding the foregoing,
   so long as there shall be no existing default in the payment of interest on
   the  bonds of the Twenty-first  Series having the  same designated interest
   rate, interest payment dates and maturity, each of such bonds authenticated
   by the  Corporate Trustee  after the Record  Date for any  interest payment
   date for  such bonds, and prior  to such interest payment  date (unless the
   Issue  Date  is  after  such  Record Date),  shall  be  dated  the  date of
   authentication, but shall  bear interest from  such interest payment  date,
   and the person  in whose name such  bond shall have been  registered at the
   close of  business on such  Record Date  shall be entitled  to receive  the
   interest  payable  on  such  interest  payment  date,  notwithstanding  the
   cancellation  of such bond upon any transfer or exchange thereof subsequent
   to  such  Record Date  and  on  or prior  to  such  interest payment  date;
   provided,  that, (i) if the Issue Date  of bonds of the Twenty-first Series
   having the  same  designated  interest  rate, interest  payment  dates  and
   maturity  shall  be after  a  Record Date  and  prior to  the corresponding
   interest  payment date, such bonds shall bear interest from the Issue Date,
   but payment of  interest shall commence on the second interest payment date
   succeeding the Issue  Date, and (ii) interest payable on  the maturity date
   will be  payable to  the  person to  whom the  principal  thereof shall  be
   payable.   "Record Date" for  bonds of the  Twenty-first Series  having the
   same designated  interest rate, interest  payment dates and  maturity shall
   mean  (A) the date  which shall be  established prior to  the date of first
   authentication of such bonds and set forth in such bonds, or (B) if no such
   date shall  be established with respect to such bonds, the date 15 calendar
   days  prior to any interest payment date for such bonds.  "Issue Date" with
   respect  to bonds  of the  Twenty-first Series  having the  same designated
   interest  rate, interest payment dates and maturity shall mean (a) the date
   which shall  be established  prior to the  date of first  authentication of
   such  bonds and set forth  in such bonds,  or (b) if no  such date shall be
   established with respect to such bonds, the date of first authentication of
   such bonds.   The principal of, and premium,  if any, and interest on, each
   bond of the Twenty-first Series shall be payable at the office or agency of
   the Company in the Borough of Manhattan, The City of New York, in such coin
   or currency  of the United States of  America as at the  time of payment is
   legal  tender for  public and  private debts.   Bonds  of the  Twenty-first
   Series shall be dated as in Section 10 of the Mortgage provided.

          (I)  Bonds of  the Twenty-first Series shall be redeemable either at
   the option  of the Company or pursuant to the requirements of the Mortgage,
   in whole at  any time,  or, if specified  on the  face of any  bond of  the
   Twenty-first Series, in  part from time  to time,  prior to maturity,  upon
   notice, as provided in Section  52 of the Mortgage, mailed at  least thirty
   (30) days prior to the date fixed for redemption, as the Board of Directors
   may  determine in  accordance with  a Resolution  filed with  the Corporate
   Trustee  referring  to  this Twentieth  Supplemental  Indenture;  provided,
   however,  that bonds  of the  Twenty-first Series  shall not  be redeemable
   pursuant to Section 64 of the Mortgage.

         (II)  At the option of the registered owner, any bonds of the Twenty-
   first  Series, upon surrender thereof,  for cancellation, at  the office or
   agency  of the Company in  the Borough of Manhattan, The  City of New York,
   shall  (subject  to  the provisions  of  Section  12  of  the Mortgage)  be
   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.

          Transfers  of  bonds of  the Twenty-first  Series may  be registered
   (subject to  the provisions of Section 12 of the Mortgage) at the office or
   agency of the Company in the Borough of Manhattan, The City of New York.

          Upon  any registration  of  transfer or  exchange  of bonds  of  the
   Twenty-first Series, the Company  may make a charge therefor  sufficient to
   reimburse it for any tax or taxes or other governmental charge, as provided
   in Section 12 of  the Mortgage, but the Company hereby  waives any right to
   make  a charge  in addition  thereto  for any  registration of  exchange or
   transfer of bonds of the Twenty-first Series.
