Ladies and Gentlemen:

Morgan Securities LLC (the “Underwriter”) U.S. $100,000,000 principal amount of its First Mortgage Bonds, 2.95% Series due 2022 (the “Offered Securities”), to be issued under that certain Mortgage Deed and Trust, dated as of January 9, 1989, with The Bank of New York Mellon Trust Company, N.A., as successor trustee (the “Trustee”), as heretofore amended and supplemented by the supplemental indentures thereto and as further amended and supplemented by a supplemental indenture dated January 1, 2012, as it may be supplemented (collectively, the “Mortgage”) pursuant to the registration statement on Form S-3 (File No. 333-170954) filed on December 3, 2010, as amended to date (the “Initial Registration Statement”). The Mortgage has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Trust Indenture Act. The United States Securities Act of 1933, as amended, is herein referred to as the “Securities Act,” and the rules and regulations of the Commission thereunder are herein referred to as the “Rules and Regulations.”

The Company hereby agrees with the Underwriter as follows:

2.Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Underwriter that:

(a)The Initial Registration Statement in respect of the Offered Securities has been filed with the Commission; the Initial Registration Statement and any post-effective amendments thereto prior to the date hereof, each in the form heretofore delivered or to be delivered to the Underwriter and, excluding exhibits to the Initial Registration Statement but including all documents incorporated by reference in the prospectus contained in such Initial Registration Statement, including any prospectus supplement relating to the Offered Securities that is filed with the Commission and deemed by virtue of Rule 430B under the Securities Act to be part of the Initial Registration Statement, became effective upon filing with the Commission; no other document with respect to the Initial Registration Statement or any document incorporated by reference therein has heretofore been filed or transmitted for filing with the Commission with respect to the offering contemplated by the Initial Registration Statement (other than documents filed after the filing date of the Initial Registration Statement under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and prospectuses filed pursuant to Rule 424(b) of the Rules and Regulations, each in the form heretofore delivered to the Underwriter); and no stop order suspending the effectiveness of the Initial Registration Statement or any post-effective amendment thereto has been issued and no proceeding for that purpose has been initiated or threatened by the Commission.

(b)A final prospectus relating to the Offered Securities has been prepared by the Company. Such final prospectus relating to the Offered Securities to be filed with the Commission pursuant to Rule 424(b) under the Securities Act (including the documents incorporated by reference therein) is hereinafter referred to as the “Prospectus.” The Prospectus, as of the Applicable Time (as defined below) and as of the Closing Date (as defined below), did not and will not include any untrue statement of a 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; provided, that the preceding sentence does not apply to statements in or omissions from the Prospectus based upon written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 7(b) hereof. For purposes of this Agreement, the “Applicable Time” is 4:30 p.m., New York City Time, on the date of this Agreement.

At the earliest time after the filing of the Initial Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) of the Offered Securities, the Company was not an “ineligible issuer” as defined in Rule 405 under the Securities Act.

(c)The Registration Statement and the Prospectus conform, and any further amendments or supplements to the Registration Statement or the Prospectus when made will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations and the Registration Statement conforms, and any further amendments or supplements to the Registration Statement when made will conform, in all material respects to the requirements of the Trust Indenture Act, and the rules and regulations of the Commission thereunder. The Registration Statement, as of the applicable effective date, and any amendments thereto as of the Closing Date did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Prospectus, as of its date and as amended or supplemented as of the Closing Date, does not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d)The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Oregon with corporate power and corporate authority (i) to own its properties and conduct its business as described in the Prospectus and (ii) to execute and deliver, and perform its obligations under, this Agreement, the Mortgage and the Offered Securities; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which it owns or leases substantial properties or in which the conduct of its business requires such qualification, except where the failure to so qualify would not have a material adverse effect on the financial condition, business or results of operations of the Company and its subsidiaries taken as a whole (a “Material Adverse Effect”).

(e)The Mortgage has been duly authorized, executed and delivered by the Company, and constitutes a valid and legally binding instrument of the Company enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law); and the Mortgage conforms to the description thereof in the Prospectus.

(f)The Offered Securities have been duly authorized by the Company and, when authenticated and delivered in accordance with the Mortgage and paid for by the purchasers thereof, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law), and will be entitled to the benefit of the security afforded by the Mortgage; and the Offered Securities conform to the description thereof in the Prospectus.

(g)No consent, approval, authorization or order of, or filing or registration by the Company with, any court, governmental agency or third party is required for the consummation of the transactions contemplated by this Agreement and the Mortgage in connection with the issuance and sale of the Offered Securities by the Company and the use of the proceeds of the offering of the Offered Securities as described in the Prospectus, except such as have been obtained or made.

(h)This Agreement has been duly authorized, executed and delivered by the Company and is a valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors' rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and subject to any principles of public policy limiting the right to enforce the indemnification and contribution provisions contained herein.

(i)Except as disclosed in the Prospectus, the Company has good and sufficient title to all the properties described as owned and good and sufficient leasehold interest in all of the properties described as leased by it (the “Properties”), subject to minor defects and irregularities customarily found in properties of like size and character that do not materially impair the use of the property affected thereby in the operation of the business of the Company.

(j)The Company is not (i) in violation of its Articles of Incorporation (the “Articles”) or its Bylaws, as amended, (ii) in default in the performance or observance of any material obligation, covenant or condition contained in any contract, agreement or other instrument to which it is a party or by which it may be bound or (iii) in violation of any order, rule or regulation applicable to the Company of any court or any federal or state regulatory body or administrative agency or other governmental body, the effect of which, in the case of (ii) and (iii), would result in a Material Adverse Effect, and neither the execution and delivery of this Agreement, the Mortgage, or the Offered Securities, the consummation of the transactions herein or therein contemplated, the fulfillment of the terms hereof or thereof nor compliance with the terms and provisions hereof or thereof will conflict with, or result in a breach of, or constitute a default under (x) the Articles or such Bylaws, or any material contract, agreement or other instrument to which it is now a party or by which it may be bound or (y) any order, rule or regulation applicable to the Company of any court or any federal or state regulatory body or administrative agency or other governmental body having jurisdiction over the Company or over its properties, the effect of which, singly or in the aggregate, would have a Material Adverse Effect.

(k)Except as disclosed in the Prospectus, there are no legal or governmental proceedings pending or to the Company's knowledge threatened against the Company or its subsidiaries that, if determined adversely to the Company or any subsidiary would be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect or a material adverse effect on the ability of the Company to perform its obligations under this Agreement or the Mortgage.

(l)The consolidated financial statements included or incorporated by reference in the Prospectus present fairly the financial condition and operations of the Company and its consolidated subsidiaries at the respective dates or for the respective periods to which they apply; such financial statements have been prepared in each case in accordance with generally accepted accounting principles consistently applied throughout the periods involved except as otherwise indicated in the Prospectus; and Deloitte & Touche LLP, who has examined certain audited financial statements of the Company, is an independent registered public accounting firm as required by the Act and the Regulations thereunder.

(m)Except as reflected in, or contemplated by, the Prospectus, since the respective most recent dates as of which information is given in the Prospectus, there has not been any change in the capital stock or long-term debt of the Company (other than changes arising from transactions in the ordinary course of business), or any material adverse change in the business, affairs, business prospects, property or financial condition of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, and since such dates there has not been any material transaction entered into by the Company other than transactions contemplated by the Prospectus, and transactions in the ordinary course of business; and the Company has no material contingent obligation that is not disclosed in the Prospectus.

(n)The Company (i) makes and keeps books, records, and accounts, which, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company and its consolidated subsidiaries and (ii) maintains a system of internal accounting controls sufficient to provide reasonable assurances that (1) transactions are executed in accordance with management's general or specific authorization; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles or any other criteria applicable to such statements and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management's general or specific authorization; and (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(o)There is and has been no failure on the part of the Company or, to the knowledge of the Company, any of the Company's directors or executive officers in their respective capacities as such, to comply in all material respects with the provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

3.Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to sell to the Underwriter, and the Underwriter agrees to purchase from the Company at a purchase price of 100.081% of the principal amount thereof plus accrued interest from January 6, 2012 to the Closing Date (as hereinafter defined), $100,000,000 principal amount of the Offered Securities.

(b)The Underwriter will 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 Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made (in the case of the Registration Statement, necessary in order to make the statements therein not misleading), 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 reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriter consists of the following information in the Prospectus: under the caption “Underwriting,” paragraphs3, 4 (second sentence only), 5 and 7; provided, however, that the Underwriter shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company's failure to perform its obligations under Section 5(a) of this Agreement.

(c)Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through forfeiture or impairment of procedural or substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation;provided, however, that the indemnified party shall have the right to employ counsel to represent the indemnified party and their respective controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 7 if the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, if in the written opinion of counsel to either the indemnifying party or the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them or the indemnifying party shall have failed to employ counsel within a reasonable period of time, and in that event the fees and expenses of one firm of separate counsel (in addition to the fees and expenses of one local counsel in each applicable jurisdiction) shall be paid by the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d)If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above 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 the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds (before deducting expenses) from the offering of the Offered Securities, received by the Company bear to the total discounts and commissions received by the Underwriter with respect to the Offered Securities, from the Company under this Agreement. The 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 relates to information supplied by the Company or the Underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

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

8.[Reserved]

9.Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities.

If the purchase of the Offered Securities by the Underwriter is not consummated for any reason other than solely because of (a) the occurrence of any event specified in clause (iii), (v), (vi) or (vii) of Section 6(c) or (b) the failure of the Underwriter to purchase the Offered Securities on the Closing Date if all of the conditions specified in Section 6 have been satisfied and the Company has complied with all of its agreements and covenants requiring compliance on or before the Closing Date, the Company will reimburse the Underwriter for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Offered Securities, provided that the Company shall not be obligated under this Section 9 to reimburse the Underwriter for any expenses (including any reasonable fees and disbursements of counsel) in excess of $200,000.

10.No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering or any other services the Underwriter may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriter, on the other, exists in connection with the offering of the Offered Securities; (ii) the Underwriter is not acting as an advisor, expert or otherwise, to the Company in connection with the offering of the Offered Securities and such relationship between the Company, on the one hand, and the Underwriter, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriter may have to the Company in connection with the offering of the Offered Securities shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriter and its affiliates may have interests that differ from those of the Company. Any review by the Underwriter of the Company, the transactions contemplated hereby or other matters related to such transactions will be performed solely for the benefit of the Underwriter and not on behalf of the Company.

Underwriting Agreement

EXHIBIT A

Form of Opinion of Mark C. Moench, General Counsel of the Company

1.To my knowledge and except for the matters disclosed in the Prospectus, there is no legal or governmental action, suit or proceeding before any court, governmental agency, body or authority, domestic or foreign, now pending or threatened against or involving the Company or any subsidiary of the Company that, if determined adversely to the Company and its subsidiaries, taken as a whole, is reasonably likely to have, individually or in the aggregate, a material adverse effect on the business, affairs, property or financial condition of the Company and its subsidiaries taken as a whole or a material adverse effect on the ability of the Company to perform its obligations under the Underwriting Agreement, the Mortgage or the Bonds.

2.The execution, delivery and performance of the Underwriting Agreement and the Mortgage and the issuance and sale of the Bonds and the use of proceeds of the Bonds as designated in the Prospectus do not and will not (A) conflict with the Articles of Incorporation or By-laws of the Company, (B) to my knowledge, conflict with, result in the creation or imposition of any lien, charge or other encumbrance, other than the Mortgage, upon any asset of the Company pursuant to the terms of, or constitute a breach of, or default under, any agreement, indenture or other instrument to which the Company is a party, or by which the Company is bound or to which any of its properties are subject or (C) to my knowledge, result in a violation of any statute, rule or regulation, or any order, judgment or decree known to me of any court or governmental agency, body or authority having jurisdiction over the Company or any of its properties, where any such conflict, encumbrance, breach, default or violation under clause (B) or (C) is reasonably likely to have, individually or in the aggregate, a material adverse effect on the business, affairs, property or financial condition of the Company and its subsidiaries taken as a whole.

3.To my knowledge, except for such consents, approvals, authorizations, registrations or qualifications as may be required under the Securities Act, the Trust Indenture Act or state securities or blue sky laws or as may be required by applicable state public utility commissions and under the Federal Power Act, no consent, authorization or order of, or filing or registration by the Company with, any court, governmental agency or third party is required in connection with the execution, delivery and performance by the Company of the Underwriting Agreement and the Mortgage, the consummation of the transactions contemplated herein and therein, and the issuance, distribution and sale of the Bonds as contemplated therein, in each case where the effect of the failure to obtain such approval, authorization, consent or order, or make such filing, is material to the Company.

4.The Company has good and sufficient title to the Properties subject to the Mortgage, which include substantially all of the permanent physical properties and franchises of the Company (other than those expressly excepted), subject only to Excepted Encumbrances and defects and irregularities customarily found in properties of like size and character that, in my opinion, do not materially impair the use of the property affected thereby in the operation of the business of the Company; the descriptions in the Mortgage of such of the Properties as are described therein are adequate to constitute the Mortgage as a lien thereon; the Mortgage constitutes a valid lien on the Properties and, to the best of my knowledge, there is no lien on the Properties prior or equal to the lien of the Mortgage, other than the exceptions enumerated above in this paragraph 4.

EXHIBIT B

Form of Opinion of Perkins Coie LLP, special counsel to the Company

1.The Company has been duly incorporated and is validly existing under the laws of Oregon as a corporation, with the corporate power and authority to own its properties and conduct its business as described in the Prospectus.

2.The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

3.The Company has all requisite corporate power and authority to enter into the Underwriting Agreement and the Supplemental Indenture, to issue the Bonds and to consummate the transactions contemplated by the Underwriting Agreement.

4.Each of the Underwriting Agreement and the Mortgage has been duly and validly authorized, executed and delivered by the Company.

5.The Mortgage constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

6. The Mortgage has been duly qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

7.The Bonds are in the form contemplated by the Mortgage, have been duly authorized by the Company for issuance and sale pursuant to the Underwriting Agreement and the Mortgage, have been duly executed and, when authenticated by the Trustee in the manner provided in the Mortgage and delivered against payment of the purchase price therefore pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance their terms, and entitled to the benefits of the Mortgage.

8.The statements in the Prospectus under the captions “Description of the Bonds” and “Description of Additional Bonds” insofar as they purport to summarize the provisions of the Mortgage and the Bonds, fairly summarize such provisions in all material respects. The statements in the Prospectus under the caption “Certain U.S. Federal Income Tax Considerations,” insofar as such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, fairly summarize the matters described therein in all material respects.

9.No approval, authorization, consent or order of, or filing with any governmental or regulatory body or agency is required in connection with the issuance and sale of the Bonds by the Company, the consummation by the Company of the transactions contemplated by the Underwriting Agreement, the due authorization, execution or delivery of the Underwriting Agreement or the due execution, delivery or performance of the Mortgage by the Company, in each case where the effect of the failure to obtain such approval, authorization, consent or order, or to make such filing, could reasonably be expected to have a Material Adverse Effect and except (a) the registration of the Bonds with the Commission under the Securities Act pursuant to the Registration Statement and (b) such as have been obtained or made.

10.The Idaho Public Utilities Commission and the Public Utility Commission of Oregon have entered appropriate orders, which to our knowledge remain in full force and effect on the date of this letter, each authorizing the issuance of the Bonds by the Company; the Company has filed a notice with the Washington Utilities and Transportation Commission regarding the issuance and sale of the Bonds that complies with the filing requirements of RCW 80.08.040 and WAC 480-100-242; the Company has filed a notice of proposed securities issuance with the Idaho Public Utilities Commission regarding the issuance and sale of the Bonds pursuant to Order No. 30489; and, together with certain exemptive orders that have been issued by each of the Public Utilities Commission of the State of California, the Public Service Commission of Utah and the Public Service Commission of Wyoming (which to our knowledge remain in full force and effect on the date of this letter), such orders and notices constitute the only approval, authorization, consent or other order of, or notification to, any governmental body legally required in connection with the regulation of the Company as a public utility for the authorization of the issuance of the Bonds by the Company pursuant to the terms of the Underwriting Agreement.

11.The Registration Statement was declared immediately effective under the Securities Act on December 3, 2010; the Prospectus was filed with the Commission pursuant to Rule 424(b) on February 28, 2012 in a manner and within the time period required by Rule 424(b) under the Securities Act; and, based solely on a telephone conversation with representatives of the Commission, as of the date hereof, no stop order suspending the effectiveness of the Registration Statements has been issued under the Securities Act and, to our knowledge, no proceedings for that purpose have been initiated by the Commission.

12.The Registration Statement, as of its effective date, including the information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, and the Prospectus, as of its date, complied as to form in all material respects with the applicable requirements of the Securities Act and the rules thereunder; it being understood, however, that we express no view with respect to the financial statements, schedules, other financial data, or exhibits included or incorporated by reference in, or omitted from, the Registration Statements, the Prospectus or Regulation S-T.

13. We have participated in conferences with officers and other representatives of the Company, you and your representatives and representatives of the independent auditors of the Company at which the contents of the Prospectus (and portions of certain documents incorporated by reference therein) and any amendments or supplements thereto were discussed. Although we assume no responsibility for the factual accuracy, completeness or fairness of any statements (except with respect to paragraph (8) in the “Opinions” portion of this letter, subject to the assumptions, exclusions and qualifications set forth in this opinion) made in (a) the Registration Statement or any amendment thereto, (b) the Prospectus or any amendment or supplement thereto, or (c) the documents incorporated by reference in the Prospectus or any further amendment or supplement thereto, nothing has come to our attention that causes us to believe that:

a. the Registration Statement or the prospectus included therein (except for the financial statements and financial schedules and other financial information included therein, as to which we make no statement) at the time the Registration Statement became effective contained any 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

b. the Prospectus (except for the financial statements and financial schedules and other financial information included therein, as to which we make no statement) as of the Applicable Time contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.
