The Company will authorize the issue and sale of $75,000,000 aggregate principal amount of its 4.53% Series 2014 First Mortgage Bonds due October 20, 2044 (the “Bonds”). Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.


Section 2.	Sale and Purchase of Bonds.

Section 2.1. Sale and Purchase of Bonds. Subject to the terms and conditions of this Agreement, the Company will issue and sell to you and you will purchase from the Company, at the Closing provided for in Section 3, Bonds in the principal amount specified opposite your name in Schedule A at the purchase price of 100% of the principal amount thereof. The Purchasers’ obligations hereunder are several and not joint obligations, and no Purchaser shall have any liability to any Person for the performance or nonperformance by any other Purchaser hereunder.

Section 2.2. Security for the Bonds. The Bonds will be issued under and will be entitled to the benefit of and secured by that certain Restated Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement dated as of November 20, 2007 (the “Restated Indenture”) between the Company and ▇▇▇▇▇ Fargo Bank, National Association (the “Indenture Trustee”), as amended by that First Supplemental Indenture dated as of September 3, 2009 (the “First Supplemental Indenture”) and as to be supplemented and amended by a Second Supplemental Indenture to be dated as of October 1, 2014 (the “Second Supplemental Indenture”), which will be substantially in the form attached hereto as Exhibit 2.2. The Restated Indenture, as supplemented by the First Supplemental Indenture and the Second Supplemental Indenture, is hereinafter referred to as the “Indenture.” The Bonds will be substantially in the form set forth in the Second Supplemental Indenture and will be dated the date of issuance

thereof, will be in the amount of $100,000 or a multiple of $1,000 in excess thereof, will bear interest on the unpaid principal amount thereof from the date of the Bonds at the rate of 4.53% per annum, payable semiannually on the twentieth day of each April and October in each year, commencing on April 20, 2015, until the principal amount thereof becomes due and payable, and will bear interest on overdue principal (including any optional prepayment of principal) and Make‑Whole Amount, if any, and (to the extent legally enforceable) on any overdue installment of interest at the Overdue Rate, whether by acceleration or otherwise, until paid, and will be expressed to mature on October 20, 2044. Interest on the Bonds will be computed on the basis of a 360‑day year consisting of twelve 30‑day months.

The Company does not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in the Disclosure Documents.

Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by the Company of this Agreement, the Bonds and the Indenture will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company (other than the Lien of the Indenture) under, any other indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by‑laws, or any other agreement or instrument to which the Company is bound or by which the Company or any of its properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company.

Section 5.7. Governmental Authorization, Etc. Assuming the accuracy of the representations of the Purchasers set forth herein, no consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement, the Bonds or the Indenture, except for (a) the filings described in Section 5.19 and (b) authorization by the Wyoming Public Service Commission under Wyoming Statutes, Title 37 Chapter 6, which authorization has been obtained and is in full force and effect and final and all periods for appeal and rehearing by third parties have expired and all conditions contained in such authorization which are to be fulfilled on or prior to the date of issuance of Bonds have been fulfilled.

Section 5.8. Litigation; Observance of Agreements, Statutes and Orders. (a) There are no actions, suits, investigations or proceedings pending or, to the knowledge of the Company, threatened against or affecting the Company or any property of the Company in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect.

(b) The Company is not in default under any term of any agreement or instrument to which it is a party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority nor is it in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws or the USA PATRIOT Act or any of the other laws and regulations that are referred to in Section 5.16) of any Governmental

Authority, which default or violation, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect.

Section 5.9. Taxes. The Company has filed all tax returns that are required to have been filed in any jurisdiction, and has paid all taxes shown to be due and payable on such returns and all other taxes and assessments, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (a) the amount of which is not individually or in the aggregate Material or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company has established adequate reserves in accordance with GAAP. The Company knows of no basis for any other tax or assessment that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company in respect of federal, state or other taxes for all fiscal periods are adequate. The federal income tax liabilities of the Company have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the fiscal year ended December 31, 2006.

Section 5.10. Title to Property; Leases. (a) The Company has good and sufficient title to its properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by the Indenture. All leases that individually or in the aggregate are Material are valid and subsisting and are in full force and effect in all material respects.

(b) Without limiting the foregoing, the Company has not since the date of its acquisition of the real property described in recitals or granting clauses, as the case may be, of the Indenture, entered into any mortgage, deed of trust or like Lien instrument other than the Indenture and other than Liens described in clauses (i) through (xii) of the definition of Permitted Encumbrances contained in the Indenture and Liens otherwise permitted by the Indenture.

Section 5.11. Licenses, Permits, Etc. (a) The Company owns or possesses all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of others.

(b) To the best knowledge of the Company, no product or service of the Company infringes in any Material respect any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person.

(c) To the best knowledge of the Company, there is no Material violation by any Person of any right of the Company with respect to any license, permit, franchise, authorization,

patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the Company.

Section 5.12. Compliance with ERISA. (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that would, individually or in the aggregate, reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to Section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or federal law or Section 4068 of ERISA, or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would not, individually or in the aggregate, be Material.

(b) The present value of the aggregate benefit liabilities under each of the Plans of the Company (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan as of such determination date allocable to such benefit liabilities by more than the amount disclosed in Note 8 of the Company’s financial statements for the year ended December 31, 2013. The term “benefit liabilities” has the meaning specified in Section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in Sections 3(26) and 3(27) of ERISA, respectively.

(c) The Company and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(d) The expected post‑retirement benefit obligation (determined as of the last day of the Company’s most recently ended fiscal year in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 715‑60, without regard to liabilities attributable to continuation coverage mandated by Section 4980B of the Code) of the Company is properly accounted for in accordance with GAAP in Note 8 of the Company’s financial statements for the year ended December 31, 2013.

(e) The execution and delivery of this Agreement and the Indenture (including, without limitation, the Second Supplemental Indenture) and the issuance, sale and delivery of the Bonds hereunder will not involve any transaction that is subject to the prohibitions of Section 406 of ERISA or in connection with which a tax could be imposed pursuant to Section 4975(c)(1)(A)‑(D) of the Code. The representation by the Company to each Purchaser in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy

of such Purchaser’s representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Bonds to be purchased by such Purchaser.

Section 5.13. Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Bonds, or any similar Securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than twenty‑five (25) other Institutional Accredited Investors, each of which has been offered the Bonds at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Bonds to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky law of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the sale of the Bonds as set forth on page 18 of the Memorandum. No part of the proceeds from the sale of the Bonds hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220).

This Section 14 shall not prohibit the Company or any other Holder of Bonds from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.


Section 15.	Confidential Information.

For the purposes of this Section 15, “Confidential Information” means information delivered to a Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement or the Indenture that is proprietary or confidential information of the Company or such Subsidiary; provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary (provided that the source of such information was not known by such Purchaser to be bound by an obligation of confidentiality to the Company or any of its Affiliates regarding such information) or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser; provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and affiliates who have agreed to be bound by the provisions of this Section 15 (to the extent such disclosure reasonably relates to the administration of the investment represented by its Bonds), (ii) its financial advisors and

other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 15, (iii) any other Holder of any Bond who has agreed to be bound by the provisions of this Section 15, (iv) any Institutional Investor to which such Purchaser sells or offers to sell such Bond or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 15), (v) any Person from which such Purchaser offers to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 15), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the NAIC or the SVO or, in each case, or any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio, including such Confidential Information, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (x) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (y) in response to any subpoena or other legal process, including in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under its Bonds and this Agreement. Each Purchaser will not, and will cause each of its Affiliates not to, use any Confidential Information in connection with purchases or sales of, or trading in, any securities of the Company or its Affiliates in violation of law. Each Purchaser hereby acknowledges that it is aware of its responsibilities under United States federal and state securities laws regarding trading in securities while in possession of material non‑public information obtained from or on behalf of the issuer thereof and with respect to providing such information to other persons who may purchase or sell securities of such issuer. Each Holder of a Bond, by its acceptance of a Bond, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 15 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any Holder of a Bond of information required to be delivered to such Holder under this Agreement or requested by such Holder (other than a Holder that is a party to this Agreement or its nominee), such Holder will enter into an agreement with the Company embodying the provisions of this Section 15.


Section 16.	Substitution of Purchaser.

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Bonds that such Purchaser agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, wherever the word “Purchaser” is used in this Agreement (other than in this Section 16), such word shall be deemed to refer to such Affiliate in lieu of such Purchaser. In the event that such Affiliate is so substituted as a purchaser hereunder and such Affiliate thereafter transfers to such Purchaser all of the Bonds then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word “Purchaser” is used in this Agreement (other than in this Section 16), such word shall no longer be deemed to refer to such

Affiliate, but shall refer to such Purchaser, and such Purchaser shall have all the rights of an original Holder of the Bonds under this Agreement.


Section 17.	Miscellaneous.

Section 17.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent Holder of a Bond) whether so expressed or not.

Anything in this Agreement or the Bonds to the contrary notwithstanding, any payment of principal of or Make‑Whole Amount or interest on any Bond that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Bond is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

Section 17.5. Construction, Etc. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant.

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof.

instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 17.7. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York, excluding choice‑of‑law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.

Section 17.8. Jurisdiction and Process; Waiver of Jury TrialSection 17.8. Jurisdiction and Process; Waiver of Jury Trial. (a) The Company irrevocably submits to the non‑exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Bonds. To the fullest extent permitted by applicable law, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

(b) The Company consents to process being served by or on behalf of any Holder of Bonds in any suit, action or proceeding of the nature referred to in Section 17.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in Section 13 or at such other address of which such Holder shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service.

(c) Nothing in this Section 17.8 shall affect the right of any Holder of a Bond to serve process in any manner permitted by law, or limit any right that the Holders of any of the Bonds may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

(d) The parties hereto hereby waive trial by jury in any action brought on or with respect to this Agreement, the Bonds or any other document executed in connection herewith or therewith.

This Bond is one of an authorized issue of Bonds of the Company known as its First Mortgage Bonds, all issued and to be issued in one or more series under and equally and ratably secured (except as any sinking, amortization, improvement, renewal or other analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the Bonds of any particular series) by a Restated Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement dated as of November 20, 2007, executed by the Company to ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented and amended by the First Supplemental Indenture dated as of September 3, 2009 and as further supplemented and amended by the Second Supplemental Indenture dated as of October 1, 2014 (the “Second Supplemental Indenture”) (said Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement and all indentures supplemental thereto being herein collectively called the “Indenture”), to which Indenture and to all indentures supplemental thereto reference is hereby made for a description of the property mortgaged and pledged, the nature and extent of the security, the terms and conditions upon which the Bonds are and are to be secured and the rights of the holders or registered owners thereof and of the Trustee in respect of such security. As provided in the Indenture, said Bonds may be issued in series, for various principal sums, may bear different dates and mature at different times, may bear interest at different rates and may otherwise vary as provided or permitted in the Indenture. This Bond is one of the Bonds described in the Indenture and designated therein as “4.53% Series 2014 First Mortgage Bonds due October 20, 2044” (the “Bonds of the Series 2014”).

As provided in the Indenture, the Bonds of the Series 2014 are subject to redemption prior to maturity at the option of the Company either as a whole at any time or in part, from time to time, and in certain other cases, at the principal amount of the Bonds so to be redeemed and accrued interest to the date fixed for redemption, together with a premium equal to the Make‑Whole Amount, if any (as defined in Section 2.3(d) of the Second Supplemental Indenture). Except as specifically set forth in the Indenture, the Bonds of the Series 2014 are not subject to optional redemption.

Pursuant to the Indenture, the Bonds of the Series 2014 are subject to redemption, in whole or in part, out of certain monies required to be deposited with the Trustee, but in such cases the redemption shall be effected at the principal amount of the Bonds of the Series 2014 to be redeemed and accrued interest to the date fixed for redemption, without premium, if redeemed pursuant to Section 10.07 of the Indenture.

If this Bond of the Series 2014 or any portion hereof (One Hundred Thousand Dollars ($100,000) or a multiple thereof) is called for redemption and payment duly provided, this Bond of the Series 2014 or such portion hereof shall cease to bear interest from and after the date fixed for such redemption.

Upon any partial redemption of this Bond of the Series 2014, at the option of the registered holder hereof this Bond of the Series 2014 may, but need not, be either (i) surrendered to the Trustee in exchange for one or more new Bonds of the Series 2014, of authorized denominations, registered in the name of such holder, in an aggregate principal amount equal to the principal amount remaining unpaid upon this Bond of the Series 2014, or (ii) submitted to the Trustee for notation hereon of the payment of the portion of the principal hereof paid upon such partial redemption.

To the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of the Bonds may be changed and modified with the consent of the Company and upon the written consent of the holders of at least sixty‑six and two‑thirds per centum (66‑2/3%) of the Bonds then outstanding and entitled to consent and, in case one or more but less than all of the series of Bonds issued under the Indenture are so affected, of at least sixty‑six and two‑thirds per centum (66‑2/3%) in principal amount of the Bonds then outstanding and entitled to consent of each series affected thereby, provided that no such change shall be made which would (i) reduce the principal of, or premium, if any, on, or the rate of interest payable on, the Bonds, or (ii) postpone the maturity date fixed in the Indenture or in the Bonds for payment of the principal of, or any installment of interest on, the Bonds, or (iii) reduce the percentage of the principal amount of Bonds the consent of the holders of which is required for the authorization of any such change or addition, or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee, and further provided that, without the consent of the holder hereof, no such change shall be made which would (i) permit the creation of any lien (not otherwise permitted by the Indenture) ranking prior to the lien of the Indenture on all or substantially all of the Mortgaged Property, or (ii) deprive the holder hereof of the lien of the Indenture upon the Mortgaged Property.

In case an Event of Default as defined in the Indenture shall occur and be continuing, the principal of all the Bonds outstanding may be declared and may become due and payable in the manner and with the effect provided in the Indenture. In the event the payment of the Bonds of the Series 2014 is accelerated pursuant to the Indenture, the aggregate principal amount hereof and interest hereon shall be payable together with the Make-Whole Amount, if any.

This Bond of the Series 2014 is a registered Bond and, subject to the restriction on transfer set forth in the legend on this Bond of the Series 2014, is transferable by the registered holder hereof in person or by the duly authorized attorney of such holder on the registration books to be kept for the purpose at the principal office of the Trustee, Registrar for the Bonds, in the City of Minneapolis, Minnesota, upon surrender of this Bond of the Series 2014 accompanied by a written instrument of transfer in form approved by the Company, duly executed by the registered bolder in person or by such attorney, and upon cancellation hereof one or more new registered Bonds without coupons, of authorized denominations, for the same aggregate principal amount, will be issued to the transferee in exchange herefor, as provided in the Indenture.

The Company and the Trustee may deem and treat the person in whose name this Bond of the Series 2014 is registered on such books as the absolute owner hereof (whether or not this Bond of the Series 2014 shall be overdue) for the purpose of receiving payment hereof, and on the account hereof and for all other purposes, and neither the Company nor the Trustee shall be affected by any notice to the contrary.

As a condition precedent to any transfer referred to above, the Company may require payment by the holder of a sum sufficient to reimburse it for any stamp tax or any other governmental charge with respect to any transfer involved therein.

No recourse shall be had for the payment of the principal of or interest on this Bond of the Series 2014, or in respect of this Bond of the Series 2014 or the Indenture, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation, either directly or through the Company, by virtue of any constitution, statute or rule of law or by enforcement of any assessment or penalty or otherwise, any and all such liability of incorporators, stockholders, officers and directors being released by the holder hereof by the acceptance of this Bond and being likewise waived and released by the terms of the Indenture.

This Bond of the Series 2014 shall not be valid or become obligatory for any purpose until the certificate endorsed hereon shall be signed by the Trustee under the Indenture.

In Witness Whereof, Cheyenne Light, Fuel and Power Company has caused these presents to be signed in its name by the facsimile signature of its President or a Vice President and its corporate seal to be imprinted hereon and attested by the facsimile signature of its Secretary or an Assistant Secretary.

The Trustee shall not register the transfer of any Bond of the Series 2014 unless it receives a certificate in the form attached hereto as Appendix A.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under applicable law or under this Second Supplemental Indenture with respect to any transfer of any interest in a Bond of the Series 2014 other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Second Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Upon any exchange or transfer of Bonds of the Series 2014, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 3.07 of the Indenture, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of Bonds of the Series 2014.

Without limiting the other indemnities provided to the Trustee, the Company shall indemnify and save the Trustee harmless from any liabilities and costs incurred by the Trustee arising out of the making of the final or any partial payment when due of the principal owing on any of the Bonds of the Series 2014 without surrender of such ▇▇▇▇ to the Trustee.

Article II

Redemption of the Bonds of the Series 2014

Section 2.1. The entire unpaid principal balance of the Bonds of the Series 2014 shall be due and payable on the stated maturity date thereof.

Section 2.2. Pursuant to the Indenture, the Bonds of the Series 2014 are subject to redemption, in whole or in part, out of certain monies required to be deposited with the Trustee, but in such cases the redemption shall be effected at the principal amount of the Bonds of the Series 2014 to be redeemed and accrued interest to the date fixed for redemption, without premium, if redeemed pursuant to Section 10.07 of the Indenture.

Section 2.3. (a) The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Bonds of the Series 2014 at 100% of the principal amount so prepaid, and the Make‑Whole Amount determined for the Settlement Date specified by the Company in such notice with respect to such principal amount. The Company, or the Trustee (at the Company’s written request in the name and at the expense of the Company), will give each registered owner of Bonds of the Series 2014 written notice (by first class mail or such other method as may be agreed upon by the Company and such registered owner) of each optional prepayment under this Section 2.3(a) not less than 10 days and not more than 60 days prior to the date fixed for such prepayment, to each such registered owner at its last address appearing on the Bond Register. Each such notice shall specify the Settlement Date (which shall be a Business Day), the aggregate principal amount of the Bonds of the Series 2014 to be prepaid on such date, the principal amount of each Bond held by such registered owner to be prepaid (determined in accordance with subsection (b) of this Section 2.3), and the interest to be paid on the Settlement Date with respect to such principal amount being prepaid, and shall be accompanied by a certificate signed by a Senior Financial Officer as to the estimated Make‑Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such Settlement Date, the Company, or the Trustee (at the Company’s written request in the name and at the expense of the Company), shall send to each registered owner of Bonds of the Series 2014 (by first class mail or by such other method as may be agreed upon by the Company and such registered owner) a certificate signed by a Senior Financial Officer specifying the calculation of such Make‑Whole Amount as of the specified

Settlement Date. As promptly as practicable after the giving of the notice and the sending of the certificates provided in this subsection, the Company shall provide a copy of each to the Trustee (unless the Company has elected in writing to have the Trustee deliver such notices and certificates, in which case the Company shall not be required to provide further copies). The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the information set forth in any such notice or certificate. The Bonds of the Series 2014 are not otherwise subject to voluntary or optional prepayment.

(b) In the case of each partial prepayment of the Bonds of the Series 2014, the principal amount of the Bonds of the Series 2014 to be prepaid shall be allocated by the Company among all of the Bonds of the Series 2014 at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment; provided that the remaining principal amount of each Bond shall be an authorized denomination.

(c) In the case of each notice of prepayment of Bonds of the Series 2014 pursuant to this Section 2.3, if cash sufficient to pay the principal amount to be prepaid on the Settlement Date (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make‑Whole Amount, if any, is not paid as agreed upon by the Company and each registered owner of the affected Bonds, or, to the extent that there is no such agreement entered into with one or more such owners, deposited with the Trustee on or before the Settlement Date, then such notice of prepayment shall be of no effect. If such cash is so paid or deposited, such principal amount of the Bonds of the Series 2014 shall be deemed paid for all purposes and interest on such principal amount shall cease to accrue. In case the Company pays any registered owner pursuant to an agreement with that registered owner, the Company shall notify the Trustee as promptly as practicable of such agreement and payment, and shall furnish the Trustee with a copy of such agreement; in case the Company deposits any cash with the Trustee, the Company shall provide therewith a list of the registered owners and the amount of such cash each registered owner is to receive. The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the information set forth in any such notice, list or agreement, and shall not be chargeable with knowledge of any of the contents of any such agreement. Any Bond prepaid in full shall be surrendered to the Company or the Trustee for cancellation (and shall not be reissued) in accordance with Section 9 of the Bond Purchase Agreement referred to in Section 3.3 of this Second Supplemental Indenture.

(d) “Make‑Whole Amount” means, with respect to any Bond of the Series 2014, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Bond of the Series 2014 over the amount of such Called Principal, provided that the Make‑Whole Amount may in no event be less than zero. For the purposes of determining the Make‑Whole Amount, the following terms have the following meanings:

“Business Day” means any day other than a Saturday, a Sunday or a day on which commercial banks in New York City are required or authorized to be closed.

“Called Principal” means, with respect to any Bond of the Series 2014, the principal of such bond that is to be prepaid pursuant to subsection (a) of this Section 2.3 or has become

or is declared to be immediately due and payable pursuant to Article XI of the Indenture, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Bond of the Series 2014, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Bonds of the Series 2014 is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Bond of the Series 2014, 0.50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Bond of the Series 2014.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one‑twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one‑twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Bond of the Series 2014, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms

of the Bonds of the Series 2014, then (for the purpose of this calculation) the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date.

“Senior Financial Officer” means the chief financial officer, principal accounting officer, treasurer or controller of the Company.

“Settlement Date” means, with respect to the Called Principal of any Bond of the Series 2014, the date on which the principal of such Bonds is to be prepaid pursuant to subsection (a) of this Section 2.3 or is declared to be immediately due and payable pursuant to Article XI of the Indenture, as the context requires.

Section 2.4. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Bonds of the Series 2014 except upon the payment or prepayment of the Bonds of the Series 2014 in accordance with the terms of this Second Supplemental Indenture and the Bonds of the Series 2014. The Company will promptly cancel all Bonds of the Series 2014 acquired by it or any Affiliate pursuant to any payment or prepayment of Bonds pursuant to any provision of this Second Supplemental Indenture and no Bonds may be issued in substitution or exchange for any such Bonds of the Series 2014.

Section 2.5. Subject to the provisions of Section 15.02 of the Indenture, all monies paid to the Trustee pursuant to Sections 2.2 and 2.3 of this Article II shall be held by the Trustee in trust for the benefit of the respective registered owners of the Bonds of the Series 2014 which are to be redeemed (in whole or in part) and shall be paid to them as provided in Article IX of the Indenture.

Section 2.6. Nothing contained in the Indenture or in any Bond shall be construed to imply any obligation upon the Trustee to make any payment, except out of monies deposited with it for such purpose by the Company.

Article III

in any dealing or transaction (including, without limitation, any investment, dealing or transaction involving the proceeds of the Bonds of the Series 2014) with any Person if such investment, dealing or transaction (i) would cause any purchaser or holder of the Bonds of the Series 2014 to be in violation of any law or regulation applicable to such purchaser or holder, or (ii) is prohibited by or subject to sanctions under any U.S. Economic Sanctions (as such term is defined in the Bond Purchase Agreement), or (c) to engage, nor shall any Affiliate of either engage, in any activity that could subject such Person or any Purchaser or holder to sanctions under CISADA (as such term is defined in the Bond Purchase Agreement) or any similar law or regulation with respect to Iran or any other country that is subject to U.S. Economic Sanctions (as such term is defined in the Bond Purchase Agreement).

Section 3.4. For purposes of determining whether an Event of Default exists with respect to the Bonds of the Series 2014, but only with respect to such Bonds, in addition to the Events of Default set forth in Sections 11.02(c), (d), (f) and (g) of the Indenture, the holders of the Bonds of the Series 2014 shall have the following Events of Default in replacement of the Events of Default set forth in Sections 11.02(a), (b) and (e)) of the Indenture or in addition to the other Events of Default set forth in such Section 11.02, as the case may be:

[_____________], 2014

To the institutional investors named

on Schedule I attached hereto

Re: 4.53% Series 2014 First Mortgage Bonds due 2044

Ladies and Gentlemen:

We have acted as special counsel to Cheyenne Light, Fuel and Power Company, a Wyoming corporation (the “Company”), in connection with the sale to you (the “Purchasers”) of $75,000,000 in aggregate principal amount of the Company’s 4.53% Series 2014 First Mortgage bonds due 2044 (the “Bonds”) to be issued under the Restated Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement between the Company and ▇▇▇▇▇ Fargo Bank, National Association (the “Trustee”) dated as of November 20, 2007 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture thereto dated as of September 3, 2009 and the Second Supplemental Indenture thereto dated as of October 1, 2014 between the Company and the Trustee (the Original Indenture, as so supplemented, being hereinafter referred to as the “Indenture”). This opinion is being delivered pursuant to Section 4.6(a)(i) of the Bond Purchase Agreement dated as of June 30, 2014 (the “Purchase Agreement”), between the Company and the Purchasers. The Bonds, the Indenture and the Purchase Agreement are hereinafter collectively called the “Transaction Documents”. Unless otherwise stated, capitalized terms used herein are used with the meanings given those terms in the Purchase Agreement.

Based upon and subject to the foregoing and the qualifications set forth in Annex A attached hereto, we advise you that in our opinion:

1.The Bonds, when authenticated by the Trustee in accordance with the terms of the Indenture and delivered against payment therefor in accordance with the terms of the Purchase Agreement, to the extent New York law is applicable thereto, will constitute valid and

binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance, voidable preference, receivership and other laws of general application affecting the enforcement of creditors’ rights, (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, whether considered in a proceeding in equity or at law, (iii) public policy considerations that may limit the rights of parties to obtain specific remedies or enforce specific terms, and (iv) governmental authority to limit, delay or prohibit the making of payments outside the United States.

2.The Indenture, to the extent New York law is applicable thereto, constitutes a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance, voidable preference, receivership and other laws of general application affecting the enforcement of creditors’ rights, laws affecting the rights of mortgagees and other secured parties generally and state laws affecting the enforcement of certain remedial provisions, provided that such state laws affecting the enforcement of certain remedial provisions will not, in our opinion, render the remedies afforded by the Indenture, to the extent New York law is applicable thereto, inadequate for the practical realization of the benefits of the security afforded thereby, (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, whether considered in a proceeding in equity or at law, (iii) public policy considerations that may limit the rights of parties to obtain specific remedies or enforce specific terms, and (iv) governmental authority to limit, delay or prohibit the making of payments outside the United States.

3.The Purchase Agreement constitutes a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance, voidable preference, receivership and other laws of general application affecting the enforcement of creditors’ rights, (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, whether considered in a proceeding in equity or at law, (iii) public policy considerations that may limit the rights of parties to obtain specific remedies or enforce specific terms, and (iv) governmental authority to limit, delay or prohibit the making of payments outside the United States.

4.Neither the execution and the delivery of the Purchase Agreement, the consummation of the transactions effected thereby and by the Indenture and the fulfillment of the terms thereof, the issuance and delivery of the Bonds nor the compliance by the Company with all the terms and provisions of the Indenture and the Purchase Agreement will result in a violation of any Generally Applicable U.S. Federal Law. As used herein, the term “Generally Applicable U.S. Federal Law” means any United States federal statute, rule or regulation

applicable to the Company other than those that are part of a regulatory scheme specifically applicable to business organizations engaged in the type of regulated business activities conducted by the Company.

5.It is not necessary in connection with the sale of the Bonds under the circumstances contemplated by the Purchase Agreement to register the offer or sale of the Bonds under Section 5 of the Securities Act of 1933, as amended, or to qualify the Indenture under the Trust Indenture Act of 1939, as amended. No other approval, authorization, consent, certificate or order of, or registration with, any United States Federal governmental body is required under Generally Applicable U.S. Federal Law in connection with the issuance and sale of the Bonds by the Company under the circumstances contemplated by the Purchase Agreement.

6.Assuming that the Company complies with the description of the use of proceeds of the sale of the Bonds contained in the Confidential Private Placement Memorandum dated June 2014 relating to the Bonds, the sale of the Bonds will not violate Regulation T, U or X of the Board of Governors of the Federal Reserve System.

Except as specifically provided below, this opinion letter may not be used or relied upon by or published or communicated to any person other than the addressees hereof, or used or relied upon for any purpose whatsoever other than in connection with the transactions contemplated by the Purchase Agreement. We hereby consent to delivery of copies of this opinion letter to the National Association of Insurance Commissioners and to any person, not otherwise an addressee hereof, who becomes an assignee of a Purchaser in accordance with the terms of the Transaction Documents, or any such prospective assignee, in each case on the condition and understanding that, except as provided below with respect to any such actual assignee, (x) such disclosure is made solely to enable such person to be informed that an opinion letter has been rendered and to be made aware of its terms, but not for the purpose of reliance, and (y) we assume no duty or liability to any person to whom such disclosure is made. We hereby further consent to reliance on this opinion letter by any such actual assignee to the same extent as the addressees hereof as if this opinion letter had been addressed and delivered to such assignee on the date hereof on the condition and understanding that (x) we assume no responsibility or obligation to consider the applicability or the correctness of this opinion letter to any person other than the addressees hereof, (y) any such reliance by an assignee must be actual and reasonable under the circumstances existing at the time of such assignment, including any circumstances relating to changes in law or to facts or other developments known to or reasonably knowable by such assignee at such time, and (z) in no event shall any assignee have any greater rights with respect to this opinion letter than did its assignor. In furtherance and not in limitation of the foregoing, our consent to such reliance shall in no event constitute a reissuance of the opinions expressed herein or otherwise extend any statute of limitations period applicable hereto on the date hereof.

Very truly yours,

FAEGRE ▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP

Annex A

To Opinion Letter

dated (_________), 2014

In rendering the accompanying opinion letter dated [________], 2014 (the “Opinion Letter”), we wish to advise you of the following additional qualifications to which such Opinion Letter is subject:

(a) As to certain facts relevant to our opinions, we have relied upon representations made by the Company in the Purchase Agreement, the assumptions set forth below as to the matters referred to therein, and upon certificates of, and information provided by, officers and employees of the Company, reasonably believed by us to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification thereof or other investigation; provided, however, that our Primary Lawyers have no Actual Knowledge concerning the factual matters upon which reliance is placed which would render such reliance unreasonable. For the purposes hereof and the accompanying Opinion Letter, the term “Primary Lawyers” means lawyers in this firm who have given substantive legal attention to representation of the Company in connection with the transactions effected pursuant to the Purchase Agreement, and the term “Actual Knowledge” means the conscious awareness by such Primary Lawyers at the time the Opinion Letter is delivered of facts or other information without any other investigation.

(b) Our Opinion Letter is limited to the laws of the State of New York and the federal laws of the United States (the “Covered Laws”), and we express no opinion as to the effect on the matters covered by our opinions of any other law. Furthermore, in rendering the opinions, we have only considered the applicability of statutes, rules, regulations and judicial decisions that a lawyer practicing in any jurisdiction the laws of which are addressed by this Opinion Letter (the “Opining Jurisdictions”) exercising customary professional diligence would reasonably recognize as being directly applicable to the Company or the transactions effected by the Transaction Documents.

(c) We express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter hereof, including without limitation the enforceability of the governing law provisions contained in any agreements or documents.

(d) We have relied, without investigation, upon the following assumptions: (i) natural persons who are involved on behalf of the Company have sufficient legal capacity to enter into and perform, on behalf of the Company, the transactions contemplated by the Transaction Documents or to carry out their respective roles in such transactions; (ii) each party to or having rights under agreements or instruments relevant hereto (other than the Company) has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreements or instruments enforceable against it; (iii) each party to or having rights under agreements or instruments relevant hereto (other than the Company) has complied with all legal requirements pertaining to its status (such as legal investment laws, foreign qualification statutes and business activity reporting requirements) as such status relates to its rights to enforce such agreements or instruments against the Company; (iv) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic

original, and all signatures on each such document are genuine; (v) there has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (vi) the conduct of the parties to or having rights under the Transaction Documents has complied with any requirement of good faith, fair dealing and conscionability; (vii) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting Covered Laws, are publicly available to lawyers practicing in Minnesota; (viii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in the Opining Jurisdictions has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (ix) documents reviewed by us (other than the Purchase Agreement, the Indenture and the Bonds) would be enforced as written and would be interpreted in a manner consistent with their interpretation under the laws of the State of Minnesota; (x) the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Transaction Documents that would result in a violation of law or constitute a breach or default under any other agreement, order or regulation; (xi) the Company will obtain any permits and governmental approvals required in the future, and take any actions similarly required, relevant to performance of the Transaction Documents; (xii) all parties to the transaction will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Transaction Documents; and (xiii) there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealings among the parties that would, in either case, define, supplement or qualify the terms of any Transaction Document.

(e) We have further assumed, without investigation, that (i) the Company has been duly organized and is validly existing and in good standing under the laws of the State of Wyoming; (ii) the Company has the power and authority under its governing documents and the laws of the State of Wyoming to execute and deliver the Transaction Documents, to perform its obligations thereunder and to consummate the transactions contemplated thereby; (iii) the Transaction Documents have been duly authorized, executed and delivered by the Company; and (iv) the Company has obtained all governmental and third party authorizations, consents, approvals and orders and has made all filings and registrations required to enable it to execute, deliver and perform its obligations under, and consummate the transactions contemplated by, the Transaction Documents, including without limitation an order of the Wyoming Public Service Commission authorizing and approving the issuance and sale of the Bonds (which authorizations, consents, approvals and orders have become final and remain in full force and effect), and such execution, delivery, performance and consummation does not and will not violate or conflict with any law, rule, regulation, order, decree, judgment, instrument or agreement binding upon the Company or its properties (it being understood that the assumption set forth in this clause (iv) does not extend to Generally Applicable U.S. Federal Law which is addressed in paragraphs 4, 5 and 6 of the Opinion Letter).

(f) The opinions expressed in the Opinion Letter are limited to the specific issues addressed and to facts and laws existing on the date hereof. By rendering such opinions, we do not undertake to advise you with respect to any other matter or of any change in such

laws or in the interpretation thereof, or of any changes in such facts, which may occur after the date hereof.

(g) Without limiting any other qualifications set forth herein, the opinions expressed in paragraphs 1, 2 and 3 of the Opinion Letter are subject to the effect of generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the enforcement of provisions of a contract that purport to require waiver of the obligations of good faith, fair dealing, diligence and reasonableness; (iii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iv) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful misconduct or unlawful conduct or insofar as such provisions otherwise contravene public policy; (v) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange; (vi) govern and afford judicial discretion regarding determination of damages and entitlement to attorneys’ fees and other costs; (vii) may permit a party who has materially failed to render or offer performance required by a contract to cure that failure unless either permitting a cure would unreasonably hinder the aggrieved party from making substitute arrangements for performance or it is important under the circumstances to the aggrieved party that performance occur by the date stated in the contract; (viii) may limit the enforceability of provisions for the payment of premiums upon mandatory prepayment to the extent any such payment constitutes, or is deemed to constitute, a penalty or forfeiture; (ix) may require mitigation of damages; and (x) provide a time limitation after which rights may not be enforced (i.e., statutes of limitation).

(h) We express no opinion as to the enforceability or effect in the Indenture or the Bonds of (i) any provision that authorizes one party to act as attorney‑in‑fact for another party; (ii) any provision waiving legal or equitable defenses or other procedural, judicial or substantive rights; or (iii) any provision that unreasonably restricts the ability of the Company to transfer any property.

(j) The opinions expressed do not address any of the following legal issues: (i) except as set forth in paragraph 5 of the Opinion Letter, federal or state securities laws and regulations, (ii) laws and regulations relating to commodity (and other) futures and indices and other similar instruments; (ii) except as set forth in paragraph 6 of the Opinion Letter, Federal Reserve Board margin regulations; (iii) the statutes and ordinances, administrative decisions and the rules and regulations of counties, towns, municipalities and special political subdivisions (whether created or enabled through legislative action at the federal, state or regional level) and judicial decisions to the extent that they deal with the foregoing; (iv) fraudulent transfer and fraudulent conveyance laws; (v) compliance with fiduciary duty and conflict‑of‑interest requirements; (vi) federal and state tax laws and regulations; (vii) federal and state racketeering laws and regulations (e.g., RICO); (viii) federal and state laws, regulations and policies concerning national and local emergency (e.g., the International Emergency Economic Powers Act, as amended), possible

judicial deference to acts of sovereign states, and criminal and civil forfeiture laws; (ix) other statutes of general application to the extent they provide for criminal prosecution (e.g., federal and state mail fraud and wire fraud statutes); and (x) laws, regulations, directives and executive orders restricting transactions with or freezing or otherwise controlling assets of designated foreign persons or governing investments by foreign persons in the United States.

(k) We express no opinion as to the creation or attachment of any lien provided in the Indenture or the necessity of making any filings in connection therewith. Furthermore, we express no opinion as to the perfection or relative priority of any lien provided in the Indenture or the necessity of making any filings in connection therewith.

(l) In rendering the opinion in paragraph 5 of the Opinion Letter, we have assumed the accuracy of the representations, warranties and agreements of (i) the Purchasers contained in the Purchase Agreement, and (ii) ▇.▇. ▇▇▇▇▇▇ Securities LLC and Mitsubishi UFJ Securities (USA), Inc. contained in the [Letters] dated [____], 2014.

(m) We express no opinion as to the enforceability or effect in the Purchase Agreement of any agreement to submit to the jurisdiction of any particular court or other governmental authority (either as to personal jurisdiction or subject matter jurisdiction), any provision restricting access to courts, any waivers of the right to jury trial, any waivers of service of process requirements that would otherwise be applicable, or any provision otherwise affecting the jurisdiction or venue of courts.

To the institutional investors named

on Schedule I attached hereto

Re: 4.53% Series 2014 First Mortgage Bonds due 2044

Ladies and Gentlemen:

We have acted as special Wyoming counsel to Cheyenne Light, Fuel and Power Company, a Wyoming corporation (the “Company”), in connection with the sale to you (the “Purchasers”) of $75,000,000 in aggregate principal amount of the Company’s 4.53% Series 2014 First Mortgage Bonds due 2044 (the “Bonds”) to be issued under the Restated Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement between the Company and ▇▇▇▇▇ Fargo Bank, National Association (the “Trustee”) dated as of November 20, 2007 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture thereto dated as of September 3, 2009 and the Second Supplemental Indenture thereto dated as of October 1, 2014 between the Company and the Trustee (the Original Indenture, as so supplemented, being hereinafter referred to as the “Indenture”). This opinion is being delivered pursuant to Section 4.6(a)(ii) of the Bond Purchase Agreement dated as of June 30, 2014 (the “Purchase Agreement”), between the Company and the Purchasers. The Bonds, the Indenture and the Purchase Agreement are hereinafter collectively called the “Transaction Documents”. Unless otherwise stated, capitalized terms used herein are used with the meanings given those terms in the Purchase Agreement.

We have made such examination of laws and facts as we have deemed necessary as a basis for our opinions set forth below. In connection with such examination, we have reviewed the following documents: (i) the Purchase Agreement, (ii) the Indenture, (iii) the form of certificate representing the Bonds, (iv) the Company’s restated articles of incorporation, as amended (the “Articles of Incorporation”), (v) the Company’s bylaws (the “Bylaws”), (vi) certain resolutions of the Board of Directors of the Company and Black Hills Corporation relating to, among other things, the execution and delivery of the Purchase Agreement and the Indenture in the name of the Company and the issuance and delivery of the Bonds, and (vii) such corporate documents and records of the Company, such certificates of public officials and officers of the Company, and such other documents and matters as we have deemed necessary or appropriate for purposes of this opinion.

Based upon and subject to the foregoing and the qualifications and assumptions set forth in Annex A attached hereto, we advise you that in our opinion:

1.The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Wyoming, with the corporate power and authority to own its properties and conduct its business as currently conducted.

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

3. The Company has full corporate power and authority to authorize, issue and sell the Bonds as contemplated by the Purchase Agreement. The Bonds have been duly authorized, and executed by the Company and, when authenticated by the Trustee in accordance with the terms of the Indenture and delivered against payment therefor in accordance with the terms of the Purchase Agreement, to the extent Wyoming law is applicable thereto, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance, voidable preference, receivership and other laws of general application affecting the enforcement of creditors’ rights, (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, whether considered in a proceeding in equity or at law, (iii) public policy considerations that may limit the rights of parties to obtain specific remedies or enforce specific terms, and (iv) governmental authority to limit, delay or prohibit the making of payments outside the United States.

4. The Indenture has been duly authorized, executed and delivered by the Company and, to the extent Wyoming law is applicable thereto, constitutes a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent transfer, fraudulent conveyance, voidable preference, receivership and other laws of general application affecting the enforcement of creditors’ rights, laws affecting the rights of mortgagees and other secured parties generally and state laws affecting the enforcement of certain remedial provisions, provided that such state laws affecting the enforcement of certain remedial provisions will not, in our opinion, render the remedies afforded by the Indenture, to the extent Wyoming law is applicable thereto, inadequate for the practical realization of the benefits of the security afforded thereby, (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, whether considered in a proceeding in equity or at law, (iii) public policy considerations that may limit the rights of parties to obtain specific remedies or enforce specific terms, and (iv) governmental authority to limit, delay or prohibit the making of payments outside the United States.

5. All approvals and authorizations of the Wyoming Public Service Commission under the Wyoming Transmitting Utility Act which are required to be obtained in connection with the issuance of the Bonds and the execution and delivery by the Company of, and the performance by the Company of its obligations under, the Transaction Documents have been duly obtained, validly issued and are in full force and effect and final, and all periods for appeal and rehearing by third

parties have expired and all conditions contained in such approvals and authorizations which are to be fulfilled on or prior to the issuance of the Bonds have been fulfilled.

6. Except for authorizations of the Wyoming Public Service Commission under the Wyoming Transmitting Utility Act, no other consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required under Wyoming law for the consummation of the transactions contemplated by the Purchase Agreement in connection with the issuance and sale of the Bonds by the Company, except such as may be required under state securities laws.

7. The execution, delivery and performance of the Purchase Agreement and the Indenture and the issuance and sale of the Bonds and compliance with the terms and provisions of the Purchase Agreement, the Indenture and the Bonds will not result in a breach or violation of any of the provisions of the Articles of Incorporation or Bylaws of the Company.

8. The Indenture is in proper form, conforming to the laws of the State of Wyoming to give and create the lien that it purports to create, and upon proper recording in the office of the County Clerk in the counties where the real property and fixtures are located and in the office of the Wyoming Secretary of State for personal property, will effectuate the lien of the Indenture.

9. To the extent it is not excepted from the lien of the Indenture, and based solely upon the [title insurance policy issued by -- ], the Company has good title to all real property specifically described in the Indenture located in the State of Wyoming, together with improvements thereon (except such properties as have been released from the lien of the Indenture in accordance with the terms thereof), subject only to: (a) taxes and assessments not yet delinquent; (b) the lien of the Indenture; (c) Permitted Encumbrances as defined in the Indenture; and (d) as to parts of the Company’s property, easements, conditions, restrictions, leases, reservations in conveyances and similar encumbrances that do not affect the Company’s use of the property in the usual course of business, certain minor defects in titles that are not material, defects in titles to certain properties that are not essential to the Company’s business, and mechanic’s lien claims being contested or not of record or for the satisfaction or discharge of which adequate provisions have been made by the Company pursuant to the Indenture.

10. The Bonds, when authenticated by the Trustee in accordance with the terms of the Indenture and delivered against payment therefor in accordance with the terms of the Purchase Agreement, will be secured by a valid and direct mortgage lien of the Indenture on all of the real properties now owned by the Company in Wyoming and not excepted from the Granting Clauses of the Indenture, and by a valid security interest on all property and rights described in the Indenture and not so excepted, in which a security interest may be created under Article 9 of the Wyoming Uniform Commercial Code, subject only to the items set forth in the preceding paragraph 9 of this opinion.

National Association of Insurance Commissioners and to any person, not otherwise an addressee hereof, who becomes an assignee of a Purchaser in accordance with the terms of the Transaction Documents, or any such prospective assignee, in each case on the condition and understanding that, except as provided below with respect to any such actual assignee, (x) such disclosure is made solely to enable such person to be informed that an opinion letter has been rendered and to be made aware of its terms, but not for the purpose of reliance, and (y) we assume no duty or liability to any person to whom such disclosure is made. We hereby further consent to reliance on this opinion letter by any such actual assignee to the same extent as the addressees hereof as if this opinion letter had been addressed and delivered to such assignee on the date hereof on the condition and understanding that (x) we assume no responsibility or obligation to consider the applicability or the correctness of this opinion letter to any person other than the addressees hereof, (y) any such reliance by an assignee must be actual and reasonable under the circumstances existing at the time of such assignment, including any circumstances relating to changes in law or to facts or other developments known to or reasonably knowable by such assignee at such time, and (z) in no event shall any assignee have any greater rights with respect to this opinion letter than did its assignor. In furtherance and not in limitation of the foregoing, our consent to such reliance shall in no event constitute a reissuance of the opinions expressed herein or otherwise extend any statute of limitations period applicable hereto on the date hereof.

Sincerely,

ANNEX A

TO OPINION LETTER

dated [ ], 2014

In rendering the accompanying opinion letter dated [________], 2014 (the “Opinion Letter”), we wish to advise you of the following additional qualifications and assumptions to which such Opinion Letter is subject:

(a) As to certain facts relevant to our opinions, we have relied upon representations made by the Company in the Purchase Agreement, the assumptions set forth below as to the matters referred to therein, and upon certificates of, and information provided by, officers and employees of the Company, reasonably believed by us to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification thereof or other investigation; provided, however, that the members of Dray, ▇▇▇▇▇▇▇, ▇▇▇▇ & ▇▇▇▇▇▇, P.C. (the “Firm”) have no Actual Knowledge concerning the factual matters upon which reliance is placed which would render such reliance unreasonable. For the purposes hereof and the accompanying Opinion Letter, the term “Actual Knowledge” means the conscious awareness by the Firm at the time the Opinion Letter is delivered of facts or other information without any other investigation.

(b) Our Opinion Letter is limited to the laws of the State of Wyoming (the “Covered Laws”), and we express no opinion as to the effect on the matters covered by our opinions of any other law. Furthermore, in rendering the opinions, we have only considered the applicability of statutes, rules, regulations and judicial decisions that a lawyer practicing in Wyoming exercising customary professional diligence would reasonably recognize as being directly applicable to the Company or the transactions effected by the Transaction Documents.

laws, foreign qualification statutes and business activity reporting requirements) as such status relates to its rights to enforce such agreements or instruments against the Company; (iv) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine; (v) there has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (vi) the conduct of the parties to or having rights under the Transaction Documents has complied with any requirement of good faith, fair dealing and conscionability; (vii) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting Covered Laws, are publicly available to lawyers practicing in Wyoming; (viii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in Wyoming has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (ix) documents reviewed by us (other than the Indenture, the Purchase Agreement and the Bonds) would be enforced as written and would be interpreted in a manner consistent with their interpretation under the laws of the State of Wyoming; (x) the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Transaction Documents that would result in a violation of law or constitute a breach or default under any other agreement, order or regulation; (xi) the Company will obtain any permits and governmental approvals required in the future, and take any actions similarly required, relevant to performance of the Transaction Documents; (xii) all parties to the transaction will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Transaction Documents; and (xiii) there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealings among the parties that would, in either case, define, supplement or qualify the terms of any Transaction Document.

(e) We have further assumed, without investigation, that the Company has obtained all governmental and third party authorizations, consents, approvals and orders and has made all filings and registrations required to enable it to execute, deliver and perform its obligations under, and consummate the transactions contemplated by, the Indenture and the Bonds, and that execution, delivery, performance and consummation does not and will not violate or conflict with any law, rule, regulation, order, decree, judgment, instrument or agreement binding upon the Company or its properties (it being understood that the assumption set forth in this clause (iv) does not extend to Covered Laws which are addressed in paragraphs 5 and 6 of the Opinion Letter).

(g) Without limiting any other qualifications set forth herein, our opinions are subject to the effect of generally applicable laws that (i) provide for the enforcement of oral

waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the enforcement of provisions of a contract that purport to require waiver of the obligations of good faith, fair dealing, diligence and reasonableness; (iii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iv) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful misconduct or unlawful conduct or insofar as such provisions otherwise contravene public policy; (v) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange; (vi) govern and afford judicial discretion regarding determination of damages and entitlement to attorneys’ fees and other costs; (vii) may permit a party who has materially failed to render or offer performance required by a contract to cure that failure unless either permitting a cure would unreasonably hinder the aggrieved party from making substitute arrangements for performance or it is important under the circumstances to the aggrieved party that performance occur by the date stated in the contract; (viii) may limit the enforceability of provisions for the payment of premiums upon mandatory prepayment to the extent any such payment constitutes, or is deemed to constitute, a penalty or forfeiture; (ix) may require mitigation of damages; and (x) provide a time limitation after which rights may not be enforced (i.e., statutes of limitation).

(i) We express no opinion as to the priority, other than perfection, of the mortgage lien or any security interest on all property and rights described in the Indenture.

(j) The opinions expressed do not address any of the following legal issues: (i) federal or state securities laws and regulations, (ii) the statutes and ordinances, administrative decisions and the rules and regulations of counties, towns, municipalities and special political subdivisions (whether created or enabled through legislative action at the federal, state or regional level) and judicial decisions to the extent that they deal with the foregoing; (iii) fraudulent transfer and fraudulent conveyance laws; (iv) compliance with fiduciary duty and conflict‑of‑interest requirements; (v) federal and state tax laws and regulations; (vi) federal and state racketeering laws and regulations (e.g., RICO); (vii) federal and state laws, regulations and policies concerning national and local emergency (e.g., the International Emergency Economic Powers Act, as amended), possible judicial deference to acts of sovereign states, and criminal and civil forfeiture laws; (viii) other statutes of general application to the extent they provide for criminal prosecution (e.g., federal and state mail fraud and wire fraud statutes); and (ix) laws, regulations, directives and executive

orders restricting transactions with or freezing or otherwise controlling assets of designated foreign persons or governing investments by foreign persons in the United States.

(k) The parties having rights under the Transaction Documents and their successors and assigns will (i) act in good faith and in a commercially reasonable manner in the exercise of any rights or enforcement of any remedies under the Transaction Documents; (ii) not engage in any conduct in the exercise of such rights or enforcement of such remedies that would constitute other than fair dealing; and (iii) comply with all requirements of applicable procedural and substantive law in exercising any rights or enforcing any remedies under the Transaction Documents.

Exhibit 4.6(a)(iii)

[SJH Letterhead]

[_____________], 2014

To the institutional investors named

on Schedule I attached hereto

Re: 4.53% Series 2014 First Mortgage Bonds due 2044

Ladies and Gentlemen:

I am General Counsel of Cheyenne Light, Fuel and Power Company, a Wyoming corporation (the “Company”), and I have acted as counsel for the Company in connection with the sale to you (the “Purchasers”) of $75,000,000 in aggregate principal amount of the Company’s 4.53% Series 2014 First Mortgage Bonds due 2044 (the “Bonds”) to be issued under the Restated Indenture of Mortgage, Deed of Trust, Security Agreement and Financing Statement between the Company and ▇▇▇▇▇ Fargo Bank, National Association (the “Trustee”) dated as of November 20, 2007 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture thereto dated as of September 3, 2009 and the Second Supplemental Indenture thereto dated as of October 1, 2014 between the Company and the Trustee (the Original Indenture, as so supplemented, being hereinafter referred to as the “Indenture”). This opinion is being delivered pursuant to Section 4.6(a)(iii) of the Bond Purchase Agreement dated as of June 30, 2014 (the “Purchase Agreement”), between the Company and the Purchasers. The Bonds, the Indenture and the Purchase Agreement are hereinafter collectively called the “Transaction Documents”. Unless otherwise stated, capitalized terms used herein are used with the meanings given those terms in the Purchase Agreement.

I have made such examination of laws and facts as I have deemed necessary as a basis for my opinions set forth below. In connection with such examination, I or persons responsible to me have examined the following documents: (i) the Purchase Agreement, (ii) the Indenture, (iii) the form of certificates representing the Bonds, and (iv) such corporate documents and records of the Company, such certificates of public officials and officers of the Company, and such other documents and matters as I have deemed necessary or appropriate for purposes of this opinion.

Based upon and subject to the foregoing and the qualifications set forth in Annex A attached hereto, I advise you that in my opinion:

2.The Company is duly qualified to do business as a foreign corporation in good standing in all jurisdictions in which its ownership or lease of property 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.No consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required under any United States Federal statute, rule or regulation that is part of a regulatory scheme specifically applicable to business organizations engaged in the type of regulated business activities conducted by the Company (“Specified U.S. Federal Law”) for the consummation of the transactions contemplated by the Purchase Agreement in connection with the issuance and sale of the Bonds by the Company, except such as have been obtained.

4.The execution, delivery and performance of the Purchase Agreement and the Indenture and the issuance and sale of the Bonds and compliance with the terms and provisions of the Purchase Agreement, the Indenture and the Bonds will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, or result in the imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to (A) Specified U.S. Federal Law or (B) any agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the properties of the Company is subject, except in the case of this clause (B) for such breaches, violations, defaults or impositions as would not, individually or in the aggregate, have a Material Adverse Effect (it being understood that my opinion under this clause (B) does not extend to compliance with any financial ratio or any limitation in any contractual restriction expressed as a dollar (or any other currency) amount).

5.The Company is not required to be registered as an “investment company” under the Investment Company Act of 1940, as amended.

5. There is no litigation or legal or governmental proceeding pending or, to my knowledge, threatened, to which the Company is a party, or to which any property of the Company is subject, that in either case challenges or questions the validity of the Transaction Documents.

Except as set forth below, this opinion letter may not be used or relied upon by or published or communicated to any person other than the addressees hereof, or used or relied upon for any purpose whatsoever other than in connection with the transactions contemplated by the Purchase Agreement. I hereby consent to delivery of copies of this opinion letter to the National Association of Insurance Commissioners and to any person, not otherwise an addressee hereof, who becomes an assignee of a Purchaser in accordance with the terms of the Transaction Documents, or any such prospective assignee, in each case on the condition and understanding that, except as provided below with respect to any such actual assignee, (x) such disclosure is made solely to enable such person to be informed that an opinion letter has been rendered and to be made aware of its terms, but not for the purpose of reliance, and (y) I assume no duty or liability to any person to whom such disclosure is made. I hereby further consent to reliance on this opinion letter by any such actual assignee to the same extent as the addressees hereof as if this opinion letter had been addressed and delivered to such assignee on the date hereof on the condition and understanding that (x) I assume no responsibility or obligation to consider the applicability or the correctness of this opinion

letter to any person other than the addressees hereof, (y) any such reliance by an assignee must be actual and reasonable under the circumstances existing at the time of such assignment, including any circumstances relating to changes in law or to facts or other developments known to or reasonably knowable by such assignee at such time, and (z) in no event shall any assignee have any greater rights with respect to this opinion letter than did its assignor. In furtherance and not in limitation of the foregoing, my consent to such reliance shall in no event constitute a reissuance of the opinions expressed herein or otherwise extend any statute of limitations period applicable hereto on the date hereof.

Sincerely,

▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇

General Counsel of

Cheyenne Light, Fuel and Power Company

ANNEX A

TO OPINION LETTER

dated [________], 2014

In rendering the accompanying opinion letter dated [________], 2014 (the “Opinion Letter”), I wish to advise you of the following additional qualifications to which such Opinion Letter is subject:

(a) As to certain facts relevant to my opinions, I have relied upon representations made by the Company in the Purchase Agreement, the assumptions set forth below as to the matters referred to therein, and upon certificates of, and information provided by, officers and employees of the Company, reasonably believed by me to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification thereof or other investigation; provided, however, that I have no Actual Knowledge concerning the factual matters upon which reliance is placed which would render such reliance unreasonable. For the purposes hereof and the accompanying Opinion Letter, the term “Actual Knowledge” means the conscious awareness by me at the time the Opinion Letter is delivered of facts or other information without any other investigation.

(b) My Opinion Letter is limited to the laws of State of South Dakota and the federal laws of the United States (the “Covered Laws”), and I express no opinion as to the effect on the matters covered by my opinions of any other law. Furthermore, in rendering the opinions, I have only considered the applicability of statutes, rules, regulations and judicial decisions that a lawyer practicing in any jurisdiction the laws of which are addressed by this Opinion Letter (the “Opining Jurisdictions”) exercising customary professional diligence would reasonably recognize as being directly applicable to the Company or the transactions effected by the Transaction Documents.

(c) I express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter hereof.

(d) I have relied, without investigation, upon the following assumptions: (i) each document submitted to me for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine; (ii) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting Covered Laws, are publicly available to lawyers practicing in South Dakota; (iii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in the Opining Jurisdictions has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (iv) documents reviewed by me including, without limitation, the Transaction Documents would be enforced as written and would be interpreted in a manner consistent with their interpretation under the laws of the State of South Dakota; (v) the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Transaction Documents that would result in a violation of law or constitute a breach or default under any other agreement, order or regulation; (vi) the Company will obtain any permits and governmental approvals required in the future, and take any actions similarly required, relevant to performance of the Transaction Documents; (vii) all parties to the transaction will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Transaction Documents; and (viii) there are no

agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealings among the parties that would, in either case, define, supplement or qualify the terms of any Transaction Document.

(e) The opinions expressed in the Opinion Letter are limited to the specific issues addressed and to facts and laws existing on the date hereof. By rendering such opinions, I do not undertake to advise you with respect to any other matter or of any change in such laws or in the interpretation thereof, or of any changes in such facts, which may occur after the date hereof.

(f) The opinions expressed do not address any of the following legal issues: (i) federal or state securities laws and regulations, (ii) laws and regulations relating to commodity (and other) futures and indices and other similar instruments; (ii) Federal Reserve Board margin regulations; (iii) the statutes and ordinances, administrative decisions and the rules and regulations of counties, towns, municipalities and special political subdivisions (whether created or enabled through legislative action at the federal, state or regional level) and judicial decisions to the extent that they deal with the foregoing; (iv) federal and state tax laws and regulations; (v) federal and state racketeering laws and regulations (e.g., RICO); (vi) federal and state laws, regulations and policies concerning national and local emergency (e.g., the International Emergency Economic Powers Act, as amended), possible judicial deference to acts of sovereign states, and criminal and civil forfeiture laws; (vii) other statutes of general application to the extent they provide for criminal prosecution (e.g., federal and state mail fraud and wire fraud statutes); and (viii) laws, regulations, directives and executive orders restricting transactions with or freezing or otherwise controlling assets of designated foreign persons or governing investments by foreign persons in the United States.

(g) For purposes of the opinions in paragraph 1 of the Opinion Letter, the opinions relating to the laws of any State other than the State of South Dakota are based solely upon a review of published compilations of the general corporation statute of such State.
