   Washington,  including the  Portland  metropolitan area.    Gas service  is

   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.


   
                                    SIGNATURES

             Pursuant  to the requirements  of the  Securities Act  of 1933 the
   registrant  certifies that  it has  reasonable grounds  to believe  that it
   meets all of the requirements  for filing on Form  S-3 and has duly  caused
   this registration statement to be signed on its  behalf by the undersigned,
   thereunto duly authorized, in the City  of Portland, and State of Oregon on
   the 23rd day of May, 1994.
