(c)                                   Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Offered Securities or until any earlier date that the Company notified or notifies the Underwriters as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement.  If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such

11

Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would 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, not misleading, (i) the Company will promptly notify the Underwriters and (ii) the Company will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(d)                                  The Company will deliver to each Underwriter, without charge, an electronic copy of each Free Writing Prospectus prepared by or on behalf of or used or referred to by the Company as each such Underwriter may reasonably request.  To the extent applicable, each such document furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission, except to the extent permitted by Regulation S-T.

(e)                                   The Company will advise the Underwriters promptly of any additional action by the PUCN pertaining to the Offered Securities.

(f)                                    The Company will furnish promptly to the Representatives and to counsel for the Underwriters one signed copy of the Registration Statement as originally filed and each amendment thereto filed prior to the date hereof and relating to the Offered Securities, including all documents incorporated therein by reference and all consents and exhibits filed therewith, as requested.

(g)                                   The Company will deliver promptly to the Underwriters such reasonable number of the following documents as the Underwriters may request: (i) the Prospectus and the Disclosure Package and (ii) to the extent not available via the Commission’s Electronic Data, Gathering, Analysis and Retrieval System (“ EDGAR ”), (1) conformed copies of the Registration Statement (excluding exhibits other than the computation of the ratio of earnings to fixed charges, the Indenture, and this Underwriting Agreement), and (2) any documents incorporated by reference in the Prospectus.

(h)                                  In connection with the offering, until the earlier of (i) 180 days following the Closing Date and (ii) the date the Representatives shall have notified the Company of the completion of the resale of the Offered Securities, neither the Company nor any of its affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(i)                                      From the date hereof through and including the Closing Date, the Company will not, without the prior written consent of the Representatives, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any United States dollar-

12

(j)                                     As soon as practicable, the Company shall make generally available to its security holders and to deliver to the Representatives an earnings statement of the Company (which need not be audited), conforming with the requirements of Section 11(a) of the Securities Act and of the Rules and Regulations (including, at the option of the Company, Rule 158 under the Securities Act), covering a period of at least twelve months beginning after the effective date of the Registration Statement as defined in Rule 158(c) of the Rules and Regulations.

(k)                                  The Company will endeavor, in cooperation with the Representatives, to qualify the Offered Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Representatives may designate, and will maintain such qualifications in effect for as long as may be required for the distribution of the Offered Securities; provided, however, that the Company shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file any general consent to service of process in any such jurisdiction or to take any other action that would subject the Company to service of process in any suits (other than those arising out of the offering of the Offered Securities) or to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject.  The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Offered Securities have been qualified as above provided.  The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities for sale in any such state or jurisdiction or the initiating or threatening of any proceeding for such purpose.

(l)                                      The Company will pay all costs incident to the authorization, issuance, sale and delivery of the Offered Securities; the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement and the Prospectus and any amendments, supplements and exhibits thereto; the costs incident to the preparation, printing and filing of the documents and any amendments and exhibits thereto required to be filed by the Company under the Exchange Act; the costs of distributing the Registration Statement as originally filed and each amendment and post-effective amendment thereto (including exhibits), any preliminary prospectus, the Prospectus and any documents incorporated by reference in any of the foregoing documents; the costs of any filings with the Financial Industry Regulatory Authority, Inc.; fees paid to rating agencies in connection with the rating of the Offered Securities; the fees and expenses of qualifying the Offered Securities under the securities laws of the several jurisdictions as provided in subsection (k) of this Section and of preparing and printing a Blue Sky Memorandum (including fees of counsel to the Underwriters in such connection not to exceed $10,000 in the aggregate); and all other costs and expenses incident to the performance of the Company’s obligations under this Underwriting Agreement (including fees and expenses of the Company’s counsel); provided that, except as provided in this Section 5(l), the Underwriters shall pay their own costs and expenses, including, without limitation, the fees and expenses of counsel to the Underwriters, any transfer taxes on the Offered Securities which they may

13

sell and the expenses of advertising any offering of the Offered Securities made by the Underwriters.

(m)                              The Company shall use the net proceeds received by it from the sale of the Offered Securities pursuant to this Agreement in the manner specified in the Disclosure Package and the Prospectus under the caption “Use of Proceeds.”

(h)                                  Pillsbury Winthrop Shaw Pittman LLP, as counsel for the Underwriters, shall have furnished to the Representatives on the Closing Date such opinions as the Representatives may reasonably require.

(i)                                      The order of the PUCN referred to in Section 2(m) hereof shall be in full force and effect and no proceedings to suspend the effectiveness of either such order shall be pending or threatened.

7.                                       Indemnification and Contribution .

(a)                                  The Company will indemnify and hold harmless each Underwriter, its partners, members, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint

15

or several, to which such Underwriter 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 Preliminary Prospectus, the Disclosure Package, 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 any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein made, in 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, including 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 Underwriting Agreement, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriters specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below; provided, further, that the foregoing indemnity with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities (or actions in respect thereof), in connection with clauses (i) through (iii) below, purchased Offered Securities, or any person controlling such Underwriter, where it shall have been determined by a court of competent jurisdiction by final and non-appealable judgment that (i) prior to the Applicable Time the Company has notified such Underwriter that the Preliminary Prospectus, dated April 9, 2018, contains an untrue statement of material fact or omits 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, not misleading, (ii) such untrue statement or omission of a material fact was corrected in an amended or supplemented Preliminary Prospectus and such corrected Preliminary Prospectus was provided to such Underwriter sufficiently in advance of the Applicable Time so that such corrected Preliminary Prospectus could have been conveyed to such person prior to the Applicable Time and (iii) such corrected Preliminary Prospectus was not conveyed to such person at or prior to the Applicable Time.

(b)                                  Each Underwriter will severally and not jointly 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 Preliminary Prospectus, the Disclosure Package, 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

16

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 such 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 any Underwriter consists solely of the information described as such in Section 12 hereof; provided, however, that the Underwriters 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 Underwriting 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.

17

(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 Underwriters 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 Underwriters 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 Underwriters 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 Underwriters with respect to the Offered Securities from the Company under this Underwriting 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 Underwriters 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), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities were purchased by it were resold exceeds the amount of any damages which such 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

(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 any Underwriter within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters 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.                                       Default of Underwriters .  If any Underwriter or Underwriters defaults in its or their obligations to purchase the Offered Securities hereunder, and the aggregate principal amount of the Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Offered Securities, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including themselves, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in

18

proportion to their respective commitments hereunder, to purchase such Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase.  If any Underwriter or Underwriters so defaults and the aggregate principal amount of the Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Offered Securities and arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Underwriting Agreement will terminate without liability on the part of the non-defaulting Underwriters or the Company, except as provided in Section 9 hereof.  As used in this Underwriting Agreement, the term “ Underwriter ” includes any person substituted for an Underwriter under this Section.  Nothing herein, including the Company’s obligations pursuant to Section 9 hereof, will relieve a defaulting Underwriter from liability for its default.

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 several Underwriters set forth in or made pursuant to this Underwriting 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 any 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 Underwriters is not consummated for any reason other than a default by one or more Underwriters, the Company shall be responsible for the fees and expenses of counsel for the Underwriters in an amount not to exceed $150,000.

10.                                No Fiduciary Duty .  The Company acknowledges and agrees that (i) the purchase and sale of the Offered Securities, including the determination of the offering price of such Offered Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and each Underwriter, on the other hand; (ii) each Underwriter is acting solely in the capacity of an arm’s-length contractual counterparty to the Company in connection with the offering of such Offered Securities and the process leading to such transaction (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an Underwriter of, the Company; (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of such Offered Securities 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 of the Offered Securities except the obligations expressly set forth in this Underwriting Agreement; and (iv) the Underwriters are not advising the Company as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction and the Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated by this Underwriting Agreement, and the Underwriters shall have no responsibility or liability to the Company with respect thereto.

Based on the foregoing and relying thereon, and subject to the assumptions, limitations, exceptions and qualifications set forth above, it is our opinion that:

3.1                                The Opinion Party has been duly organized and is validly existing and in good standing under the laws of the State of Nevada as a corporation;

3.2                                The Opinion Party has the corporate power and authority to own, lease and operate its property and conduct its business as described in the Disclosure Package and the Prospectus, and to authorize, execute, deliver and perform its obligations under the Transaction Documents, including without limitation the authorization, offering, issuance and sale of the Offered Securities;

3.4                                The Underwriting Agreement has been duly and validly authorized, executed and delivered by the Opinion Party;

3.5                                To the extent Nevada law governs, the Indenture constitutes a valid and binding agreement on the part of the Opinion Party, enforceable against the Opinion Party in accordance with its terms, except as enforcement may be limited by applicable bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by equitable principles generally;

3.6                                The Offered Securities have been duly and validly authorized, and, to the extent Nevada law governs such issues, upon authentication thereof by the Trustee in accordance

A- 7

with the Indenture and payment therefor as provided in the Underwriting Agreement, will be validly issued and outstanding, enforceable against the Opinion Party in accordance with their terms, except as enforcement may be limited by applicable bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by equitable principles generally;

3.7                                The PUCN has entered an appropriate Order, which to our knowledge remains in full force and effect on the date of this letter, which authorizes or permits the issuance of the Offered Securities by the Opinion Party; and such Order constitutes the only approval, authorization, consent or other order of, or notification to, any governmental body legally required by the State of Nevada in connection with the regulation of the Opinion Party as a public utility for the authorization of the execution, delivery, and performance by the Opinion Party of the Underwriting Agreement and the issuance of the Offered Securities by the Opinion Party pursuant to the terms of the Underwriting Agreement.  To our knowledge, other than the Order, no consent, approval, authorization or order of, or filing or registration by the Opinion Party with, any Nevada court, Nevada governmental agency or third party is required for the consummation by the Opinion Party of the transactions contemplated by the Transaction Documents or the performance by the Opinion Party of its obligations thereunder, except such as have been obtained or made;

3.8                                To the best of our knowledge, there are no legal or governmental actions, suits or proceedings before any courts or governmental agencies now pending, threatened against, or involving the Opinion Party or any of its subsidiaries (i) of a character that are required to be disclosed in the Registration Statement, the Disclosure Package, or the Prospectus and which are not adequately disclosed in the Registration Statement, the Disclosure Package, or the Prospectus; (ii) that, if determined adversely to the Opinion Party or any of its subsidiaries 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 Opinion Party to perform its obligations under the Transaction Documents; or (iii) that would call into question the validity of the Transaction Documents or the authority of the Opinion Party to enter into the Transaction Documents to which it is a party;

3.9                                The execution, delivery and performance by the Opinion Party of the Transaction Documents to which it is a party and the issuance and sale of the Offered Securities and the use of proceeds of the Offered Securities as designated in the Disclosure Package and he Prospectus do not and will not:  (A) conflict with the corporate charter or by-laws of the Opinion Party; or (B) result in a violation of any Nevada statute, rule, regulation, order, judgment or decree of any courts or governmental agencies in Nevada having jurisdiction over the Opinion Party or any of its affiliates or any of their properties, where any such conflict, encumbrance, breach, default or violation under this clause (B) is reasonably likely to have, individually or in the aggregate, a Material Adverse Effect or a material adverse effect on the ability of the Opinion Party to perform its obligations under the Transaction Documents;

3.10                         Except for minor defects or irregularities, the Opinion Party has good and marketable title to all real property acquired in fee title (and not subsequently disposed of) by the Opinion Party in the State of Nevada since August 13, 2003, subject only to the lien of the Indenture and Permitted Liens (as defined in the Indenture);

A- 8

3.11                         Except as otherwise set forth in this Opinion Letter, the exceptions from coverage identified on Schedule B to the 2001 Title Policy and held by the Trustee, constitute Permitted Liens; provided, however , that in giving this opinion we have relied on the Property Certificate without any independent investigation, to the effect, among other things, that such exceptions meet the non-materiality and/or other qualifications set forth in clauses (c), (d), (e) and/or (g) in the definition of Permitted Liens in the Indenture;

3.12                         Except as otherwise set forth in this Opinion Letter, the exceptions from coverage referred to on Schedule B to the 2003 Title Policy held by the Trustee constitute Permitted Liens; provided, however , that in giving this opinion we have relied on the Property Certificate without any independent investigation, to the effect, among other things, that such exceptions meet the non-materiality and/or other qualifications set forth in clauses (c), (d), (e) and/or (g) in the definition of Permitted Liens in the Indenture;

3.13                         The Indenture, which was properly filed and recorded, constitutes a valid mortgage lien on the real properties located in the State of Nevada that are specifically or generally described or referred to in the Indenture as being subject to the Lien thereof (and not subsequently released from such Lien), enforceable against the Opinion Party in accordance with its terms, provided, however, that, except as stated in paragraph 3.10, we express no opinion regarding the priority of any mortgage lien so recorded. The security interest granted by the Opinion Party to the Trustee in the Indenture constitutes a duly perfected security interest in the fixtures and personal property located in the State of Nevada which are specifically or generally described or referred to in the Indenture as being subject to the security interest granted therein (and not subsequently released from such Lien), to the extent that, under the Code, a security interest in such property can be perfected by the filing of a financing statement, which perfected security interest is enforceable against the Opinion Party in accordance with its terms, provided, however, that, except as stated in paragraph 3.10, we express no opinion regarding the priority of any lien so perfected.  The Indenture by its terms effectively subjects to the Lien thereof all property located in the State of Nevada (other than Excepted Property, as defined in the Indenture) acquired by the Opinion Party after the date of the execution and delivery of the Indenture (and not subsequently released from such Lien), subject to no Lien prior to the Lien of the Indenture except Permitted Liens, any Lien thereon existing at the time of such acquisition and any Lien for unpaid portions of the purchase price thereof placed thereon at the time of such acquisition, and also except as otherwise provided in Article XIII of the Indenture and except for possible claims of a trustee in bankruptcy and possible claims and taxes of the federal government;

3.14                         No taxes (as distinguished from filing and recordation fees) are payable to the State of Nevada, or any subdivision or agency thereof, in connection with the execution and delivery of the Underwriting Agreement establishing the series and terms of the Offered Securities or the issuance and sale of the Offered Securities, and all filing and recording fees as to the Indenture have been paid.

This Opinion Letter is made with the knowledge and understanding that the addressees  (but no other persons) may rely thereon in connection with the transactions provided for in the Transaction Documents and is solely for the addressees’ benefit, and this Opinion Letter may not be disclosed to or relied upon by any person other than the addressees, except that (i) this Opinion Letter may be disclosed to independent auditors, bank examiners, legal counsel, regulatory and

C.                                     Opinions

Based on the foregoing and subject to the qualifications and exclusions stated below, we express the following opinions:

C-1                             The Indenture constitutes a valid and binding agreement on the part of the Company, enforceable against the Company in accordance with its terms.

C-2                             The Notes, when executed by the Company and authenticated by the Trustee in accordance with the Indenture and delivered against payment of the purchase price as provided in the Underwriting Agreement, will be validly issued and outstanding, enforceable against the Company in accordance with their terms and entitled to the benefit and security of the Indenture ratably with all other securities outstanding thereunder.

C-3                             The execution and delivery of the Transaction Documents by the Company and the performance by the Company of its obligations thereunder:  (i) to our

B- 3

knowledge, will not constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance (other than the lien of the Indenture) upon any property or assets of the Company pursuant to any agreement filed by the Company as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (each, a “ Material Agreement ”); and (ii) to our knowledge, will not result in any violation of any statutory laws that counsel exercising customary professional judgment would in our experience reasonably recognize as typically applicable to agreements similar to the Transaction Documents, except, in the case of (i) and (ii), as would not reasonably be likely to have a Material Adverse Effect.

C-4                             To our knowledge, and subject to paragraph E-6 and except for matters related to U.S. state securities laws and regulations and non-U.S. laws and regulations, 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 Notes by the Company, the consummation by the Company of the transactions contemplated by the Underwriting Agreement, or the due authorization, execution or delivery of the Transaction Documents by the Company, except such as (i) have been obtained or made by the Company and are in full force and effect or (ii) if not obtained or made, would not reasonably be likely to have a Material Adverse Effect on the validity or enforceability of the Notes or the transactions contemplated by the Transaction Documents or the ability of the Company to perform its obligations thereunder.

C-5                             The documents incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus as they pertain to the Company (other than the financial statements and financial schedules therein, as to which we express no opinion), when they were filed with the Commission, complied as to form in all material respects with the requirements of the Exchange Act.

C-6                             Without independent verification of the factual accuracy, completeness or fairness of any statements made in the Registration Statement, the Preliminary Prospectus and the Prospectus, each of the Registration Statement and Prospectus (except for the financial statements and financial schedules and other financial information included therein, as to which we express no opinion) appears on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder.

C-7                             The statements in the Preliminary Prospectus and the Prospectus under the captions “Description of General and Refunding Mortgage Securities—Description of the G&R Indenture” and “Description of the Notes,” in each case insofar as the statements purport to summarize the provisions of the Indenture and the Notes, fairly summarize such provisions in all material respects.

B- 4

C-8                             The Company is not, and immediately upon receipt of payment for the Notes will not be, an “investment company” required to be registered under the Investment Company Act.

C-9                             The Registration Statement was declared effective under the Securities Act on October 18, 2016; the Preliminary Prospectus was filed with the Commission pursuant to Rule 424(b) on April   , 2018 in a manner and within the time period required by Rule 424(b) under the Securities Act; the Prospectus was filed with the Commission pursuant to Rule 424(b) on April   , 2018 in a manner and within the time period required by Rule 424(b) under the Securities Act; and, based solely on the contents of the Commission’s stop orders webpage located at www.sec.gov/litigation/stoporders.shtml, as of    a.m. on the date hereof, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and, to our knowledge, no proceedings for that purpose have been initiated by the Commission.

C-10                      To the extent New York state law governs such matters, the security interest granted by the Company to the Trustee in the Indenture has attached within the meaning of Section 9-203 of the Uniform Commercial Code of the State of New York (the “UCCNY”) with respect to such portion of the Mortgaged Property (as defined in the Indenture) that constitutes personal property or fixtures in which a security interest can be granted under Article 9 of the UCCNY.

C-11                      The Indenture has been duly qualified under the Trust Indenture Act.

D.                                     Confirmations

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 Registration Statement, the Disclosure Package and 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 (other than as set forth in paragraph C-7 above, subject to the assumptions, exclusions and qualifications set forth in this opinion) made in (a) the Registration Statement or any amendment thereto, (b) the Disclosure Package or any amendment or supplement thereto, (c) the Prospectus or any amendment or supplement thereto, or (d) 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 (except for the financial statements and financial schedules and other financial information included therein, as to which we make no statement), as of the most recent date the Registration Statement became effective pursuant to Rule 430B(f)(2) of the Securities Act, 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- 5

(b)                                  the Disclosure Package (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 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 in which they were made, not misleading, or

(c)                                   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 its date and as of the date hereof 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.
