At the time the Registration Statement was filed with the Commission and at the time of the most recent amendment, if any, to the Registration Statement for purposes of complying with Section 10(a)(3) of the 1933 Act, the Company met the requirements for use of Form S-3 under the 1933 Act.

At the time the Registration Statement became effective, and at the Effective Time, the Registration Statement complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act and the 1939 Act Regulations.

No order preventing or suspending the use of any Preliminary Prospectus has been issued by the Commission.

(E) Issuer Free Writing Prospectuses. At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities, the Company was not an “ineligible issuer” as defined in Rule 405. Each Issuer Free Writing Prospectus, at the time it was filed with the Commission pursuant to Rule 433 or, if it was not required to be so filed, at the time of each use thereof (1) did not include any information that conflicts with (x) information contained in the Registration Statement, including any prospectus or prospectus supplement that is part of the Registration Statement, and not superseded or modified, or (y) information contained in the Company’s periodic and current reports filed with the Commission pursuant to Section 13 or 15(d) of the 1934 Act that are incorporated or deemed incorporated by reference in the Registration Statement, and not superseded or modified, and (2) complied in all other respects with the requirements of Rule 164 and Rule 433 (without reliance on subsections (b), (c) and (d) of Rule 164 of the 1933 Act Regulations). No order preventing or suspending the use of any Issuer Free Writing Prospectus has been issued by the Commission.

(F) Content of the Disclosure Package. The Disclosure Package, at and as of the Applicable Time, did not, and at and as of the Closing Time, will not, contain any untrue statement of material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The Prospectus delivered to the Underwriters in connection with the offering of the Securities, and any amendment or supplement thereto, will be identical to the copies thereof filed electronically with the Commission pursuant to XXXXX (except that the registration fee table will be deleted from the cover thereof), except to the extent permitted by Regulation S-T.

(H) Description and Filing of Contracts and Documents. All contracts or documents that are required to be described in the Registration Statement, the Pricing Prospectus or the Prospectus or to be filed as exhibits to the Registration Statement have been so described and filed as required.

The representations and warranties of the Company in this subsection (a)(i) shall not apply to any of the information referred to on Schedule D.

(iv) Financial Statements.

The selected financial data and the summary financial information included in the Registration Statement, the Disclosure Package and the Prospectus present fairly the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement. The financial statements and other financial data included in the Registration Statement, the Disclosure Package and the Prospectus comply in all material respects with the requirements of paragraph (e) of Item 10 of Regulation S-K.

Except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus, neither the Company nor any of its subsidiaries has any off-balance sheet arrangements of the character contemplated by Item 303 of Regulation S-K or otherwise by Section 13G of the 1934 Act, or has any other contingent obligation or liability, which, in any case, is material, or is reasonably likely to be material, to the Company and its consolidated subsidiaries considered as one enterprise.

(v) No Material Adverse Change. Since the date of the latest audited balance sheet included in the Registration Statement, the Disclosure Package and the Prospectus and except as disclosed therein, there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse

change, in the condition (financial or otherwise), business, properties or results of operations of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (any such change or development, a “Material Adverse Change”).

(vi) Good Standing of the Company and Designated Subsidiaries. Each of the Company and each of the Designated Subsidiaries has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation and has the corporate power and authority to own or lease and operate its properties and to conduct its business as described in the Registration Statement, the Disclosure Package and the Prospectus, and the Company has the corporate power and authority to enter into and perform its obligations under this Agreement; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not have a material adverse effect on the condition (financial or otherwise), business, properties or results of operations of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (any such effect, a “Material Adverse Effect”).

(vii) No Significant Subsidiaries. The Company has no “significant subsidiaries” as defined in Rule 1-02 of Regulation S-X.

(viii) Capitalization. The authorized, issued and outstanding capital stock of the Company is as set forth in the Registration Statement, the Disclosure Package and the Prospectus. All of the issued and outstanding shares of Common Stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable. All of the issued and outstanding shares of capital stock of each Designated Subsidiary have been duly authorized and validly issued, are fully paid and non-assessable and are owned, directly or indirectly, by the Company, free and clear of any security interest, mortgage or other lien or encumbrance (each being hereinafter called a “Lien”).

(ix) Authorization of this Agreement. This Agreement has been duly authorized, executed and delivered by the Company.

(x) Authorization of the Mortgage. The Mortgage has been duly authorized, and, at the Closing Time, will have been duly executed and delivered, by the Company and will constitute a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general principles of equity. At the Closing Time, the Mortgage will have been duly qualified under the 1939 Act.

(xi) Authorization of the Securities. The Securities have been duly authorized by the Company and, at the Closing Time, will have been duly executed by the Company; and, when the Securities have been (A) authenticated and delivered by the

Trustee and (B) issued and delivered by the Company against payment of the purchase price therefor as provided in this Agreement, the Securities will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general principles of equity, and will be entitled to the benefits of the Mortgage equally and ratably with all other securities outstanding thereunder.

(xii) Descriptions of the Mortgage and the Securities. The descriptions of the Mortgage and the Securities in the Registration Statement, the Disclosure Package and the Prospectus are accurate in all material respects, and the Supplemental Indenture and the Securities will be in substantially the respective forms filed or incorporated by reference as exhibits to the Registration Statement.

(xiii) Absence of Defaults. Neither the Company nor any Designated Subsidiary is in violation of its articles of incorporation or by-laws or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or such Designated Subsidiary is a party or by which it or such Designated Subsidiary may be bound, or to which any of the property or assets of the Company or such Designated Subsidiary is subject (collectively, “Agreements and Instruments”) except for such defaults as, singly or in the aggregate, would not result in a Material Adverse Effect.

(xiv) No Conflict. The execution and delivery by the Company of this Agreement, the consummation by the Company of the transactions contemplated herein and therein (including the issuance and sale by the Company of the Securities and the use of the proceeds from the sale of the Securities as described in the Registration Statement, the Disclosure Package and the Prospectus) and the compliance by the Company with its obligations hereunder, 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 or Repayment Event (as defined below) under, or result in the creation or imposition of any Lien upon any property or assets of the Company or any Designated Subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or Liens as, singly or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect), nor will such action result in any violation of the articles of incorporation or by-laws of the Company or any Designated Subsidiary or of any statute of any jurisdiction applicable to the Company or any Designated Subsidiary or any rule, regulation or order applicable to the Company or any Designated Subsidiary of any regulatory body, administrative agency or other governmental body or any court that, in any such case, has jurisdiction over the Company or any Designated Subsidiary or any of their respective assets, properties or operations. As used herein, a “Repayment Event” means any event or condition that gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any Designated Subsidiary.

(xv) Absence of Proceedings. 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, to the knowledge of the Company, threatened, against or affecting the Company or any of its subsidiaries, that (A) is required to be disclosed in the Registration Statement, the Pricing Prospectus or the Prospectus and is not disclosed as required, (B) could materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder or (C) except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus, would reasonably be expected to result in a Material Adverse Effect; and the aggregate of all pending legal or governmental proceedings to which the Company or any of its subsidiaries is a party or of which any of their respective properties or assets is the subject that are not described in the Registration Statement, the Disclosure Package and the Prospectus, including ordinary routine litigation incidental to the business, would not reasonably be expected to result in a Material Adverse Effect.

(xvi) Absence of Further Requirements. The Washington Utilities and Transportation Commission (the “WUTC”), the Idaho Public Utilities Commission (the “IPUC”) and the Public Utility Commission of Oregon (the “OPUC”) have issued orders authorizing the issuance and sale by the Company of the Securities as contemplated in this Agreement and the Mortgage; the Montana Public Service Commission (the “MPSC”) has issued an order disclaiming jurisdiction over the issuance of securities and the creation of liens by the Company pursuant to, and on the terms set forth in such order (such order, collectively with the aforesaid orders of the WUTC, the IPUC and the OPUC, being hereinafter called the “PUC Orders”); the PUC Orders are in full force and effect as of the date hereof; and, except for informational filings required under the PUC Orders, no further consent, approval or authorization of, or registration, filing or declaration with, any regulatory or other governmental body or agency is required in connection with the execution, delivery or performance by the Company of this Agreement or the issuance and sale by the Company of the Securities.

(xvii) Title to Property; Lien of Mortgage. (A) The Company has good and marketable title in fee simple to all of its real estate and fixed properties and good title to all of its other property, in each case free and clear of all Liens except (1) the lien of the Mortgage, (2) leases of minor portions of the Company’s property to others for uses which do not interfere with the Company’s business, (3) leases of certain property of the Company not used in its utility business, (4) Excepted Encumbrances (as defined in the Mortgage) and (5) encumbrances, defects and irregularities customarily found in properties of like size and character, which, in the Company’s opinion, do not materially impair the use of the property affected thereby in the operation of the business of the Company;

(B) Upon the due execution, delivery and appropriate recording of the Supplemental Indenture, the Mortgage will constitute, subject only to the exceptions referred to in clauses (2) through (5) in subparagraph (A) above, a direct and valid first mortgage Lien for the security of the Bonds and all other securities issued and outstanding and to be outstanding under the Mortgage on substantially all of the physical properties and franchises of the Company other than those expressly excepted;

(C) The description in the Mortgage of the properties intended to be subject to the Mortgage is adequate for the Mortgage to constitute a Lien thereon; and

(D) The Mortgage (excluding the Supplemental Indenture) has been duly and properly recorded as a mortgage on real estate and fixtures in the proper offices of the respective counties in which the real estate and other physical properties of the Company are located, and filed, together with appropriate financing statements, as a security interest in personal property in the offices of the Secretaries of State of the States of Washington, Idaho, Montana and Oregon; the Supplemental Indenture will be so recorded and filed forthwith; and no other recording or filing of the Mortgage is or will be necessary to maintain or perfect of record the Lien thereof other than periodic continuation statements in respect of such security interests.

(xviii) Leases.

Each Underwriter severally (and not jointly) agrees to indemnify and hold harmless the Company, its directors and officers, 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 against any and all loss, liability, claim, damage and expense described in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions of a material fact in or from, or alleged untrue statements or omissions of a material fact in or from, the information referred to in Schedule D.

(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 to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this Section 7. In the case of parties indemnified pursuant to Section 7(a), counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 7(b), counsel to the indemnified parties 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 parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties 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 could be sought under this Section 7 or contribution could be sought under Section 8 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.

SECTION 8. Contribution.

If the indemnification provided for in Section 7 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, (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 public offering price of the Securities, as so set forth.

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 or by any Underwriter 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 8 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 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing 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 of a material fact or omission or alleged omission of a material fact.

Notwithstanding the provisions of this Section 8, 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 0000 Xxx) with respect to the offering of Securities pursuant to this Agreement shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each affiliate, director and officer of each Underwriter and each person, if any, who controls such 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, 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 8 are several (and not joint) in proportion to the principal amounts of Securities set forth opposite their respective names in Schedule A hereto.

SECTION 9. Representations, Warranties and Agreements to Survive.

All of the respective representations, warranties and agreements of the Company and several Underwriters contained in this Agreement, or in certificates of officers of the Company delivered pursuant to this Agreement, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, or any director, officer or controlling person of such Underwriter, or by or on behalf of the Company, or any director, officer or controlling person of the Company, and shall survive delivery of and payment for the Securities.

SECTION 10. Termination of Agreement.

(a) Termination. The Representatives may terminate this Agreement, by notice to the Company, at any time prior to the Closing Time

(i) if there has been since the date of the latest audited balance sheet included in the Pricing Prospectus any Material Adverse Change, or

(ii) if there has occurred any material adverse change in the financial markets in the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to offer, sell or deliver the Securities or to enforce contracts for the sale of the Securities, or

(iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange or the NYSE American or in the NASDAQ Global Market or the NASDAQ Global Select Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of such exchanges or Nasdaq Stock Market, Inc. with respect to such markets or by order of the Commission or any other governmental authority, or

(iv) if a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or

(v) if a banking moratorium has been declared by either federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof; and provided, further, that Sections 2, 7, 8 and 9 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters.

If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are then obligated to purchase under this Agreement (the “Defaulted Securities”), the non-defaulting Underwriters shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters approved by the Company, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the non- defaulting Underwriters shall not have completed such arrangements within such 24 hour period, then:

(i) if the amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 5 (it being understood that the fees and expenses referred to in clause (v) of Section 5(a) would in such event be payable by the Representatives) and except that Sections 2, 7, 8 and 9 shall survive any such termination and remain in full force and effect with respect to any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for a defaulting Underwriter under this Section 11.

SECTION 12. Notices.

All notices, requests and other communications hereunder shall be in writing and shall be deemed to have been duly given if received by mail, electronic mail or transmitted by any standard form of telecommunication to the addresses set forth in this Section or to such other address as such party shall have specified most recently by written notice.

SECTION 13. Parties in Interest.

This Agreement shall inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors. Nothing expressed in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the affiliates, directors, officers and controlling persons referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any of the Underwriters shall be deemed to be a successor by reason merely of such purchase.

SECTION 14. No Advisory or Fiduciary Relationship.

The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter is and has been acting solely on its own behalf and is not the agent or fiduciary of the Company, or its shareholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters), and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in, and may in the future engage in, a broad range of transactions that involve interests that differ from those of the Company and (e) no Underwriter has provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15. Governing Law; Time; Consent to Jurisdiction.

This Agreement and any claim, controversy or dispute arising out of or otherwise relating to this Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed within the State of New York without giving effect to principles of conflicts of laws thereof. Specified times of day refer to New York City time. Any action, suit or proceeding to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal court located in the Southern District of the State of New York or any New York state court located in the Borough of Manhattan, and the Company agrees to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom), and each party waives (to the fullest extent permitted by law) any objection it may have to the levying of venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding has been brought in an inconvenient forum.

SECTION 16. Waiver of Jury Trial.

To the fullest extent permitted by law, the Company and each Underwriter hereby irrevocably waive any right they may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or any transaction contemplated hereby.

SECTION 17. Counterparts.

This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same agreement.

SECTION 18. Entire Agreement.

This Agreement supersedes all prior and contemporaneous agreements and understandings (whether written or oral) between the Company and the Underwriters with respect to the subject matter of this Agreement.

SECTION 19. Effect of Headings.

The Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 20. Severability.

This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof or thereof shall not affect the validity or enforceability hereof or thereof or of any term or provision hereof or thereof.

A security rating is not a recommendation to buy, sell or hold securities and should be evaluated independently of any other rating. Each rating is subject to revision or withdrawal at any time by the assigning rating organization. Each security rating agency has its own methodology for assigning ratings, and, accordingly, each rating should be considered independently of all other ratings.

Pursuant to Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade securities prior to the date that is two business days before the settlement date will be required, by virtue of the fact that the securities initially will settle T+5 (on May 22, 2018), to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of securities who wish to trade securities prior to the date that is two business days before the settlement date should consult their own advisors.
