SECOND AVENUE, PORTLAND, OREGON 97209, OR BY CALLING THE FOLLOWING NUMBER: 503-226-4211. 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 ----------------------------------------------- March 31, December 31, ------ ------------------------------------- 1994 1993 1992 1991 1990 1989 ---- ---- ---- ---- ---- ---- 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.

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.
