Free Writing Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading, or if it is necessary (or, if the Representative or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly notify the Representative of such event or condition and of its intention to file such amendment or supplement (or, if the Representative or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representative of its intention to prepare such amendment or supplement) and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

whether any transaction described in clause (i) or (iii) above is to be settled by delivery of Common Stock, other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

SECTION 6.Indemnification.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or any “issuer information” (as defined in Rule 433), or any “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided,however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or in any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Underwriters as aforesaid consists of the information described as such in Section 6(b) hereof.

(b)Indemnification by the Underwriters.Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statementand each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative expressly for use therein.

(c)Actions against Parties; Notification.Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder or otherwise. Counsel to the indemnified parties shall be selected as follows: counsel to the Underwriters and the other indemnified parties referred to in Section 6(a) above shall be selected by the Representative, and counsel to the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 6(a) above and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)Settlement Without Consent if Failure to Reimburse.If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7.Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not

only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate of any Underwriter, each officer, director, employee, partner and member of any Underwriter or any such affiliate, and eachperson, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8.Representations, Warranties and Agreements to Survive Delivery.

whether any transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock, other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

Notwithstanding the provisions set forth in the immediately preceding paragraph, the undersigned may, without the prior written consent of J.P. Morgan, transfer any Common Stock or other capital stock or any securities convertible into or exchangeable or exercisable for Common Stock or other capital stock:

(1) if the undersigned is a natural person, as a bona fide gift or gifts or by will, by intestate succession or pursuant to aso-called “living trust” or other revocable trust established to provide for the disposition of property on the undersigned’s death, in each case to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, or as a bona fide gift or gifts to a charity or educational institution,

New York, NY 10179

Ladies and Gentlemen:

I am Senior Vice President and General Counsel of Northwest Natural Holding Company, an Oregon corporation (the “Company”), and have acted as counsel to the Company in connection with the issuance and sale by the Company of [·] shares of its Common Stock (the “Securities”) pursuant to an Underwriting Agreement between the Company and the several underwriters named therein, for whom you are acting as representative, dated [·], 2019 (the “Underwriting Agreement”). Capitalized terms used herein and not otherwise defined have the meanings ascribed to such terms in the Underwriting Agreement. This opinion is rendered to you pursuant to Section 5(b) of the Underwriting Agreement.

In my capacity as such counsel, I have either participated in the preparation of or have examined and am familiar with:

(a) the Company’s Amended and Restated Articles of Incorporation (the “Articles of Incorporation”), and the Company’s Amended and Restated Bylaws, as amended through May 23, 2019 (the “Bylaws”);

(f) a specimen of the Company’s common stock certificate certified as a true and correct representation of the common stock certificate used by the Company when the Company elects pursuant to the Bylaws to issue certificates for some or all of any shares of the Common Stock (“Specimen Certificate”); and

(g) the records of various corporate proceedings relating to the authorization and issuance of the Securities by the Company and the authorization, execution and delivery by the Company of the Underwriting Agreement.

E-1

I have also examined or caused to be examined such other documents and have satisfied myself as to such other matters as I have deemed necessary in order to render this opinion. In such examination, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals, and the conformity to the originals of the documents submitted to me as certified or photostatic copies and the authenticity of the originals of such latter documents. I have not examined the Securities, except a specimen thereof.

As to questions of fact material to the opinions expressed herein, I have relied upon certifications and representations of responsible officers of the Company, the Company’s transfer agent and registrar, you and appropriate public officials and upon information set forth in the Registration Statement, the General Disclosure Package or the Prospectus, in each case without independent verification of such matters, except as otherwise described herein.

Subject to the foregoing and to the further exceptions and qualifications set forth below, I am of the opinion that:

(1) The Company is validly existing as a corporation under the laws of the State of Oregon.

(2) The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and in the Prospectus and to enter into and perform its obligations under the Underwriting Agreement.

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

(4) (A) The Company has the authorized capitalization as set forth in the General Disclosure Package and the Prospectus, (B) the Securities have been duly authorized for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth in the Underwriting Agreement, will be validly issued, fully paid andnon-assessable; and (C) no holder of the Securities is or will be subject to personal liability by reason of being such a holder under the charter orby-laws of the Company or the laws of the State of Oregon.

(5) The sale of the Securities to the Underwriters pursuant to the Underwriting Agreement is not subject to any preemptive rights, rights of first refusal or other similar rights of any securityholder of the Company or any other person arising under the charter or bylaws of the Company, the laws of the State of Oregon or, to my knowledge, otherwise.

(6) The form of certificate used to evidence the Common Stock complies in all material respects with all applicable requirements of the laws of the State of Oregon, and with any applicable requirements of the charter andby-laws of the Company.


		E-2

(7) To my knowledge, except as otherwise disclosed in the General Disclosure Package and the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or threatened, against or affecting the Company or any of its subsidiaries which is required to be disclosed in thePre-Pricing Prospectus or the Prospectus, as the case may be, or which might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or to materially and adversely affect the consummation of the transactions contemplated in the Underwriting Agreement or the performance by the Company of its obligations thereunder.

(8) The information in thePre-Pricing Prospectus and the Prospectus under the captions “Description of Common Stock,” the information in the Company’s Annual Report onForm 10-K for the fiscal year ended December 31, 2018 under the captions “Business—Regulation and Rates” and “Legal Proceedings” (as such information under such captions in such Annual Report on Form10-K is modified or supplemented in subsequent reports filed pursuant to the 1934 Act and the 1934 Act Regulations), in each case to the extent that it constitutes matters of law, summaries of legal matters, summaries of provisions of the Company’s charter or bylaws, summaries of legal proceedings, or legal conclusions, is correct in all material respects.

(9) All descriptions in the Registration Statement, the General Disclosure Package and the Prospectus of any Company Documents are accurate in all material respects.

(10) To my knowledge, there are no franchises, contracts, indentures, mortgages, deeds of trust, loan or credit agreements, bonds, notes, debentures, evidences of indebtedness, leases or other instruments or agreements required to be described or referred to in the Registration Statement, thePre-Pricing Prospectus or the Prospectus or the documents incorporated or deemed to be incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

(11) (A) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency (other than under the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations, which have been obtained, or as may be required under the state securities or blue sky laws, as to which we have not been called upon to express an opinion), (B) no authorization, approval, vote or other consent of any stockholder of the Company, (C) no authorization, approval, waiver or consent under any Subject Instrument, and (D) to my knowledge, no other authorization, approval, vote or other consent of any other person or entity, is necessary or required for the authorization, execution or delivery of the Underwriting Agreement by the Company for the offering of the Securities as contemplated by the Underwriting Agreement or for the issuance, sale or delivery of the Securities.

		E-3

under the caption “Use of Proceeds”) and compliance by the Company with its obligations under the Underwriting Agreement do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default, Termination Event or Repayment Event under, or result in the creation or imposition of any Lien upon any property or assets of the Company or any of its subsidiaries pursuant to, (x) any Subject Instrument or (y) any other Company Document, except for such conflicts, breaches, defaults or Liens that would not, individually or in the aggregate, result in a Material Adverse Effect, nor will such action result in any violation of the provisions of the Organizational Documents of the Company or any Subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to me, of any government, government instrumentality or court having jurisdiction over the Company or any of its subsidiaries or any of their respective assets, properties or operations.

In connection with the transactions contemplated by the Underwriting Agreement, I have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants and counsel for the Company and representatives of the Underwriters, at which conferences the contents of the Registration Statement, the General Disclosure Package and the Prospectus, and any supplements or amendments to any of the foregoing, and related matters were discussed. Although, other than with respect to the opinions expressed in paragraphs (8) and (9), I am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements in the Registration Statement, the General Disclosure Package, the Prospectus or any supplements and amendments to any of the foregoing, and have made no independent check or verification thereof, nothing has come to my attention that would lead me to believe that:

(1)

the Registration Statement or any post-effective amendments thereto, at the respective times they first were declared became effective or at any subsequent time that the Company filed an Annual Report on Form10-K or any amendment thereto, or the Registration Statement (including the Rule 430B Information), at each deemed new effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), 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;

(2)

the General Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted 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; or

(3)

the Prospectus and any supplements thereto, as of the date of the Prospectus, as of the date of any such supplement or the date of this letter, included or includes an untrue statement of a material fact or omitted 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,


		E-4

except in each case that I make no statement nor express any belief with respect to financial statements and schedules and other financial or statistical data included or incorporated by reference in or omitted from the Registration Statement, the General Disclosure Package, or the Prospectus or any amendment or supplement to any of the foregoing, 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 matters arising under the federal laws of the United States and the laws of the States of Oregon.

This opinion is solely for your benefit and the benefit of the other Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and it may not be relied upon in any manner by any other person or for any other purpose, without my prior written consent, except that Morgan, Lewis & Bockius LLP may rely on this opinion as to all matters of Oregon law in rendering its opinion required to be delivered under the Underwriting Agreement. This opinion is expressed as of the date hereof, and I do not assume any obligation to update or supplement it to reflect any fact or circumstance that hereafter comes to my attention, or any change in law that hereafter occurs.

Very truly yours,
