Ladies and Gentlemen:

 

I am General Counsel of Black Hills Corporation, a South Dakota corporation (the “Company”), and I have acted as counsel for the Company in connection with the Registration Statement and with respect to the issuance and sale by the Company of up to four million six hundred thousand (4,600,000) shares of the Company’s Common Stock, $1.00 par value per share (the “Shares”), (including up to six hundred thousand (600,000) shares subject to an over-allotment option granted by the Company to the underwriters offering the Shares) offered pursuant to that certain Prospectus Supplement dated April 24, 2003 (the “Prospectus Supplement”). As described in the Prospectus Supplement, the Company is selling the Shares pursuant to an Underwriting Agreement dated April 24, 2003 (the “Underwriting Agreement”), between the Company and Credit Suisse First Boston LLC, Lehman Brothers Inc., Credit Lyonnais Securities (USA) Inc., BMO Nesbitt Burns Corp., Gerard Klauer Mattison & Co., Inc., ABN AMRO Rothschild LLC, D.A. Davidson & Co., NatCity Investments, Inc. and Scotia Capital (USA) Inc., as representatives of the underwriters.

 

In reaching the conclusions expressed in this opinion, I or persons responsible to me, have (a) examined the Articles of Incorporation and Bylaws of the Company, the Registration Statement, the Prospectus Supplement and such certificates of public officials and of corporate officers and directors and such other documents and matters as I have deemed necessary or appropriate for the purpose of rendering this opinion, (b) relied upon the accuracy of facts and information set forth in all such documents, and (c) assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as copies, and the authenticity of the originals from which all such copies were made.

 

Based on the foregoing, I am of the opinion that the Shares have been duly authorized and, when issued, delivered and paid for in accordance with the terms and conditions of the Underwriting Agreement, will be validly issued, fully paid and non-assessable shares of Common Stock of the Company.
