The Securities will be issued, and the terms thereof established, from time-to-time, by the Company in accordance with the respective Indentures.

(h) Other than as set forth or contemplated in the Prospectus, there are no legal or governmental proceedings pending to which the Company is a party or to which

any property of the Company is subject, which, if determined adversely to the Company, would individually or in the aggregate have a material adverse effect on the consolidated financial position, stockholders’ equity or consolidated results of operations of the Company, and, to the best of the Company’s knowledge, no such proceedings are threatened.

2. Obligations of the Agents and the Company.

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

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

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

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

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


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

From 18 months to less than 2 years	.200	%

3. Sales to Agents as Principal. Each sale of Securities to an Agent, as principal, shall be made in accordance with the terms of this Agreement and (unless the Company and such Agent shall otherwise agree) a separate agreement (each a “Terms Agreement”), which will provide for the sale of such Securities to, and the purchase thereof by, such Agent, as principal. A Terms Agreement may be either (i) a written agreement substantially in the form of Annex II hereto, or (ii) an oral agreement between any Agent and the Company confirmed in writing by such Agent. A Terms Agreement may also specify certain provisions relating to the reoffering of such Securities by such Agent. Each Terms Agreement shall specify the principal amount of Securities to be purchased by an Agent pursuant thereto, the price to be paid to the Company for such Securities, any provisions relating to the rights of, and defaults by, any underwriters acting together with such Agent in the reoffering of the Securities, the time and date of delivery of and payment for such Securities (each, a “Time of Delivery”) and place of delivery of such Securities, and any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 5 hereof. Each purchase of Securities, unless otherwise agreed shall be at a discount equivalent to the commission payable to an Agent, acting as agent, with respect to a sale of Securities of identical maturity, as set forth in Section 2(e)

hereof). The Agent may engage the services of any other broker or dealer in connection with the resale of the Securities purchased as principal and may allow any portion of the discount received in connection with such purchase from the Company to be paid to such brokers and dealers. The commitment of an Agent to purchase Securities as principal, whether pursuant to a Terms Agreement or otherwise, shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and, to the extent not otherwise agreed upon in a Terms Agreement or otherwise, shall be subject to the terms and conditions herein set forth.

(l) To pay or cause to be paid the following: (i) the fees and expenses of the Company’s counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any Preliminary Prospectus, the Prospectus and any Pricing Supplements and all other amendments and supplements thereto and the mailing and delivering of copies thereof to such Agent; (ii) the fees and expenses of counsel for the Agents in connection with the establishment of the program contemplated hereby, any opinions to be rendered by such counsel hereunder and the transactions contemplated hereunder; (iii) the cost of preparing this Agreement, any Terms Agreement and any other documents approved by the Company in connection with the offering, purchase,

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

7. Conditions to Company’s Obligations.

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

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

8. Indemnification.

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

prior to written confirmation of the sale involved (assuming that the Company shall have previously furnished such documents to such Agent in a timely fashion), and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities.

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

(c) Promptly after receipt by an indemnified party under Section 8(a) or Section 8(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such Section. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party); provided, however, in no event shall such indemnifying parties be obligated to retain more than one counsel (and necessary local counsel), in addition to counsel for such indemnifying parties, to represent the indemnified parties, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such Section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.

Each indemnified party may also participate at its own expense in the defense of any such action. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) no statement as to or an admission of fault, culpability or failure to act by or on behalf of an indemnified party.

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

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

liability which such Agent may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

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

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

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

12. Notices. Except as otherwise specifically provided herein or in the Administrative Procedure, all statements, requests, notices and advices hereunder shall be in writing or by telephone, if promptly confirmed in writing, and if to Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, shall be sufficient in all respects when delivered or sent by facsimile transmission or registered mail to 4 World Financial Center, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attn: MTN Product Management, Facsimile Transmission No. 000-000-0000, Telephone No. 000-000-0000, if to UBS Securities LLC, shall be sufficient in all respects when delivered or sent by facsimile transmission or registered mail to 000 Xxxxxxxxxx Xxxx., Xxxxxxxx, Xxxxxxxxxxx 00000, Facsimile Transmission No. 000-000-0000, Attn: Xxxxxxxx Blue, Managing

ANNEX I

Northwest Natural Gas Company

Administrative Procedure

This Administrative Procedure relates to the Securities defined in the Distribution Agreement, dated September 28, 2004 (the “Distribution Agreement”), amongst Northwest Natural Gas Company (the “Company”), on the one hand, and Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, UBS Securities LLC, X.X. Xxxxxx Securities Inc., Xxxxx Xxxxxxx & Co. and each other person which shall become a party thereto (each, an “Agent” and, together, the “Agents”), on the other. Defined terms used herein and not defined herein shall have the meanings given such terms in the Distribution Agreement or the Indentures. An Agent, in relation to a purchase of a Security by a purchaser solicited by such Agent, is referred to herein as the “Selling Agent” and, in relation to a purchase of a Security by such Agent as principal other than pursuant to a Terms Agreement, as the “Purchasing Agent”. As used herein, the term “business day” shall mean any day when banks in New York City are not authorized or obligated by law or executive order to remain closed.

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

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

Order No. 04 248 dated May 11, 2004, of the Oregon Public Utility Commission (the “OPUC”) authorizes the issuance and sale of the Securities, subject to the conditions set forth in such order. In addition, such order of the OPUC authorizes the issuance and sale by the Company (i) only of Securities bearing interest at fixed rates, established within the maximum all-in spreads over Benchmark Treasury Yields for various maturities (determined in accordance with said orders as of the time the commitment to purchase any Securities is received by the Company and the Agent) and (ii) of Securities to Agents, as principal, at 100% of the principal amount thereof less a percentage not to exceed the commission applicable to an agency sale of Securities of the same maturity. Prior to the solicitation of offers to purchase any Securities, and the issuance and sale of such Securities, the Company will obtain one or more orders of the Washington Utilities and Transportation Commission (the “WUTC”) establishing compliance with applicable statutory provisions with respect to the issuance and sale of such Securities and establishing conditions with respect thereto.

As stated in the Company’s Prospectus Supplement dated September 28, 2004 and the accompanying Prospectus dated February 18, 2004, if the terms of any Security, as determined by the Company, provide that such Security will be redeemable at the option of the Company, such Security will be made redeemable in whole or in part.

Procedure for Rate Changes:

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

Acceptance or Rejection of Offers by Company:

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

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

Settlement:

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

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

Settlement Procedures:

A. After the acceptance of an offer by the Company, the Selling Agent or Purchasing Agent, as the case may be, will communicate the following details of the terms of such offer (the “Sale Information”) to the Company by telephone (confirmed in writing) or by facsimile transmission or other acceptable written means:

Suspension of Solicitation; Amendment or Settlement:

Subject to its representations, warranties and covenants contained in the Distribution Agreement, the Company may instruct the Agents to suspend solicitation of purchases at any time. Upon receipt of such instructions, the Agents will forthwith suspend solicitation of offers to purchase from the Company until such time as the Company has advised them that solicitation of offers to purchase may be resumed.

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

Delivery of Confirmation and Prospectus to Purchaser by Selling Agent:

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

I-6

Instruction from Company to Trustee for Preparation of Securities:

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

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

Procedures for Book-Entry Securities:

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

The ownership interest of such beneficial owner in such Security issued in book-entry form will be recorded through the records of such Participants or through the separate records of such Participants and one or more indirect participants in DTC.

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

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

B		2:00 p.m. on the trade date

D-E		9:00 a.m. on Settlement Date
F		10:00 a.m. on Settlement Date

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

(2)

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

(3)

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

I-13

Failure of Purchaser to Pay Selling Agent:

Certificated Securities

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

Book-Entry Securities

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

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

I-14

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

With reference to the issuance and sale from time-to-time by Northwest Natural Gas Company (the “Company”), pursuant to the Distribution Agreement, dated September 28, 2004 (the “Agreement”), between the Company and each of you, of not to exceed $160,000,000 in aggregate principal amount of (i) the Company’s First Mortgage Bonds, designated Secured Medium-Term Notes, Series B (the “Secured Notes”) to be issued under the Company’s Mortgage and Deed of Trust, dated as of July 1, 1946, to Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company) (the “Corporate Trustee”) and R.G.

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

I am of the opinion that:

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

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

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

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

III-2

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

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

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

8. The Secured Notes have been duly authorized by the resolutions adopted by the Company’s Board of Directors on May 27, 1993, September 26, 1996, April 24, 1997, February 26, 1998, April 27, 2000, April 25, 2002 and December 18, 2003 (the “Board Resolutions”), and when the terms of the Secured Notes shall have been determined as contemplated by and in accordance with the Mortgage, the Board Resolutions and written orders or instructions evidencing determinations by officers of the Company, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Mortgage.

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

10. The Notes, when (a) executed by the Company, (b) completed, authenticated and delivered by the Corporate Trustee or the Indenture Trustee, as the case may be, (c) issued and delivered by the Company and (d) paid for, all as contemplated by and in accordance with the Mortgage, in the case of Secured Notes, the Indenture, in the case of Unsecured Notes, the

III-3

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

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

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

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

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

In the course of the preparation by the Company of the Registration Statement and the Prospectus, I had conferences with certain officers and employees of the Company, but I have made no independent verification of the accuracy or completeness of the representations and statements made to me by such person or the information included by the Company in the

III-4

Registration Statement and the Prospectus, and take no responsibility therefor, except as set forth in paragraph 12 hereof. However, my examination of the Registration Statement and the Prospectus and my discussions in the above-mentioned conferences did not disclose to me any information which causes me to believe that, when the Registration Statement became effective, it contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that, as of the date of this opinion, the Prospectus includes an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that I do not express any belief as to the financial statements or other financial or statistical data contained in the Registration Statement or the Prospectus, or as to the Forms T-1 or T-2, or as to any information contained therein furnished to the Company in writing by any of you expressly for use therein.

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

I do not express any opinion herein concerning any law other than the laws of the State of Oregon and the Federal laws of the United States. In rendering this opinion, I have relied, with your consent, as to certain matters of Washington law, upon the opinion of even date herewith addressed to you by Stoel Rives LLP, special Washington counsel to the Company, and, as to all matters governed by the laws of the State of New York, the 1933 Act, the Securities Exchange Act of 1934 and the Trust Indenture Act, upon the opinion of even date herewith addressed to you by Xxxxxx Xxxx & Priest LLP, New York, New York, counsel for the Company.

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

Very truly yours,

Xxxx X. Xxxxxxx, Esq.

Ladies and Gentlemen:

With reference to the issuance and sale from time-to-time by Northwest Natural Gas Company (the “Company”), pursuant to the Distribution Agreement, dated September 28, 2004 (the “Agreement”), between the Company and each of you, of not to exceed $160,000,000 in aggregate principal amount of (i) the Company’s First Mortgage Bonds, designated Secured Medium-Term Notes, Series B (the “Secured Notes”), to be issued under the Company’s Mortgage and Deed of Trust, dated as of July 1, 1946, to Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company) (the “Corporate Trustee”) and R.G. Page (Xxxxxxx Xxxx, successor), as trustees, as supplemented by twenty supplemental indentures (such Mortgage and Deed of Trust, as so supplemented, being hereinafter called the “Mortgage”), and (ii) the Company’s Unsecured Medium-Term Notes, Series B (the “Unsecured Notes”), to be issued under the Company’s Indenture, dated as of June 1, 1991 (the “Indenture”), to Deutsche Bank Trust Company Americas, as trustee (the “Indenture Trustee”) (the Secured Notes and the Unsecured Notes being hereinafter collectively referred to as the “Notes”), and the appointment of each of you as agents of the Company pursuant to the Agreement for the purposes of soliciting and receiving offers to purchase Notes, as agents, and purchasing Notes, as principals, from the Company, please be advised that, as counsel to the Company, we have participated in the preparation of or reviewed (a) the Restated Articles of Incorporation, as amended, and Bylaws, as amended, of the Company; (b) the Mortgage; (c) the Indenture; (d) the Agreement;

(e) the registration statement (File No. 333-112604) (the “Registration Statement”), filed by the Company with the Securities and Exchange Commission (the “SEC”) for the registration under the Securities Act of 1933, as amended (the “1933 Act”), of $200,000,000 of the Company’s securities (which may include the Notes), and for the qualification under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), of the Mortgage and the Indenture, which Registration Statement became effective on February 18, 2004; (f) the prospectus, dated February 18, 2004, constituting a part of the Registration Statement in the form in which the Registration Statement became effective, or if such prospectus has been amended or supplemented subsequent to such effectiveness, as so amended and supplemented, including the documents incorporated therein by reference pursuant to Item 12 of Form S-3, as supplemented by the prospectus supplement relating to the Notes, dated September 28, 2004, filed with the Commission pursuant to Rule 424(b) under the Securities Act (together, the “Prospectus”); (g) the records of the proceedings before the Oregon Public Utility Commission (the “OPUC”) and the Washington Utilities and Transportation Commission (the “WUTC”) relating to the issuance and sale of the Notes; and (h) the records of various corporate and other proceedings relating to the authorization, issuance and sale of the Notes. We have also examined such other documents and satisfied ourselves as to such other matters as we have deemed necessary in order to render this opinion. We have not examined the Notes, except specimens thereof.

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

We are of the opinion that:

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

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

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

4. The form of the Secured Notes has been duly authorized and has been established in conformity with the provisions of the Mortgage and conforms to the description thereof contained in the Prospectus; the form of the Unsecured Notes, bearing interest at a fixed

IV-2

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

5. The Secured Notes have been duly authorized by the resolutions adopted by the Company’s Board of Directors on May 27, 1993, September 26, 1996, April 24, 1997, February 26, 1998, April 27, 2000, April 25, 2002 and December 18, 2003 (the “Board Resolutions”), and when the terms of the Secured Notes shall have been determined as contemplated by and in accordance with the Mortgage, the Board Resolutions and written orders or instructions evidencing determinations by Officers of the Company, such terms will have been duly authorized by the Company and will have been established in conformity with the terms of the Mortgage.

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

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

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

IV-3

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

10. The Registration Statement has become effective under the 1933 Act, and, to our knowledge, no stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose are pending before or have been proposed by the SEC; the Mortgage and the Indenture have been duly qualified under the Trust Indenture Act; the Registration Statement at the time it became effective complied, and the Prospectus (excluding the documents incorporated therein by reference) as of the date of this opinion complies, as to form, in all material respects with the requirements of the 1933 Act, the Trust Indenture Act (except with respect to the Forms T-1 and Form T-2, upon which we express no opinion) and the rules and regulations of the SEC thereunder; and the documents incorporated by reference in the Prospectus pursuant to Item 12 of Form S-3 (other than the financial statements and other financial or statistical data contained therein, upon which we express no opinion), as of their respective dates of filing, complied as to form in all material respects with the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC thereunder.

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

This opinion is limited to the facts and law at the date hereof. In rendering the opinions set forth in paragraphs 7 and 9 above, we have necessarily assumed that, at the time of any issuance, sale and delivery of a Note (i) the Board of Directors of the Company (or any committee thereof acting pursuant to authority properly delegated to such committee by the Board of Directors) has not taken any action to rescind or otherwise reduce its prior authorization

IV-4

of the issuance of the Notes and an officer of the Company, as stated in the resolutions of the Board of Directors (or any such committee) relating to the Notes, has executed and delivered such Notes, (ii) the WUTC has issued an order or orders establishing compliance with applicable statutory provisions with respect to the issuance and sale of such Note, (iii) the orders of the OPUC and the WUTC with respect to the Notes being sold remain in full force and effect and have not been modified or amended by the OPUC or the WUTC, respectively, and the Company complies with the terms of such orders and (iv) the order of the SEC with respect to the Registration Statement, the Mortgage and the Indenture remains in full force and effect and has not been modified or amended by the SEC.

We do not express any opinion herein concerning any law other than the laws of the State of Oregon, the State of Washington and the Federal laws of the United States. Accordingly, in rendering this opinion, we have relied, with your consent, as to all matters governed by the laws of the State of Oregon, upon the opinion of even date herewith addressed to you by Xxxx X. Xxxxxxx, Esq., General Counsel of the Company, and, as to all matters governed by the laws of the State of Washington, upon the opinion of Stoel Rives LLP, special Washington counsel to the Company. We understand that you are relying upon the opinions of Xxxx X. Xxxxxxx, Esq., and Stoel Rives LLP as to all matters governed by the laws of the State of Oregon and Washington, as the case may be, including titles to property and franchises and the lien of the Mortgage, upon which we express no opinion.

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

Very truly yours,

XXXXXX XXXX & PRIEST LLP

Ladies and Gentlemen:

the Washington Utilities and Transportation Commission (the “WUTC”) relating to the issuance and sale of the Notes. We have also examined such other documents and satisfied ourselves as to such other matters as we have deemed necessary in order to render this opinion. We have not examined the Notes, except for forms thereof.

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

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

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

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

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

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

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

This opinion is limited to the facts and law at the date hereof. In rendering the opinions set forth in paragraph 4 above, we have necessarily assumed that, at the time of any issuance, sale and delivery of a Note (i) the Board of Directors of the Company (or any committee thereof acting pursuant to authority properly delegated to such committee by the Board of Directors) has not taken any action to rescind or otherwise reduce its prior authorization of the issuance of the Notes and an officer of the Company, as stated in the resolutions of the

V-2

Board of Directors (or any such committee) relating to the Notes, has executed and delivered such Notes, (ii) the WUTC has issued an order or orders establishing compliance with applicable statutory provisions with respect to the issuance and sale of such Note, and (iii) that each such order of the WUTC with respect to the Notes being sold remains in full force and effect and has not been modified or amended by the WUTC and the Company complies with the terms of each such order.

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

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

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

Very truly yours,

STOEL RIVES LLP

ANNEX VI

[Contents of Letter of Independent Public Accountants]

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

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

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

3. On the basis of limited procedures, not constituting an examination made in accordance with generally accepted auditing standards, including a reading of the latest available interim financial statements of the Company, if any, a reading of the minute books of the Company since December 31, 2003, inquiries of officials of the Company responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that:

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

(b) at the date of the latest available interim balance sheet of the Company and at a subsequent specified date not more than five days prior to the Time of Delivery, there has been any change in the capital stock (except for (i) shares of the Company’s Common Stock issued under the Company’s Dividend Reinvestment Plan, Restated Stock Option Plan or Employee Stock Purchase Plan, (ii) shares of Common Stock issued upon the conversion of the Company’s Convertible Debentures, (iii) shares of Common Stock repurchased pursuant to the Company’s Repurchase Program, (iv) 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, and (v) shares of the Company’s Preference Stock redeemed pursuant to the mandatory redemption provisions applicable thereto) or any increase in the long-term debt of the Company, or any decrease in net assets, in each case as compared with amounts shown in the balance sheet as of the date of the latest financial statements incorporated by reference in the Registration Statement, except in each case for changes, increases or decreases which the Registration Statement discloses have occurred or may occur, which were occasioned by the declaration of dividends or which are described in such letter; or

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

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

We have also examined such other documents and satisfied ourselves as to such other matters as we have deemed necessary in order to render this opinion. We have not examined the Notes, except for forms thereof.

Based upon the foregoing and subject to the following qualifications, we are of the opinion that the WUTC has issued an order dated , 200 in Docket - , establishing compliance with applicable statutory provisions with respect to the issuance and sale by the Company of up to $ aggregate principal amount of the Notes; and under the laws of the State of Washington, no further approval, authorization, consent or other order of any public board or body is legally required for the issuance and sale of such Notes through each of you, as agent, on the terms and conditions set forth in the Agreement.

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

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

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

Very truly yours,

STOEL RIVES LLP
