This opinion letter is based as to matters of law solely on the Colorado Business Corporation Act, as amended and the Colorado Corporations and Associations Act, as amended.  We express no opinion herein as to any other laws, statutes, ordinances, rules, or regulations.  As used herein, the terms “Colorado Business Corporation Act, as amended” and the “Colorado Corporations and Associations Act, as amended” include the statutory provisions contained therein, all applicable provisions of the Colorado Constitution and reported judicial decisions interpreting these laws.

Based upon, subject to and limited by the foregoing, we are of the opinion that, following (i) issuance of the Shares pursuant to the terms of the Underwriting Agreement, dated February 17, 2011, by and among the Company and the underwriters named therein and (ii) receipt by the Company of the consideration for the Shares specified in the resolutions of the Pricing Committee of the Board of Directors, the Shares will be validly issued, fully paid and nonassessable.

This opinion letter has been prepared for use in connection with the filing by the Company of a Current Report on Form 8-K relating to the offer and sale of the Shares, which Form 8-K will be incorporated by reference into the Registration Statement and Prospectus, and speaks as of the date hereof.  We assume no obligation to advise you of any changes in the foregoing subsequent to delivery of this letter.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the above-described Current Report on Form 8-K and to the reference to this firm under the caption “Legal Matters” in the Prospectus.  In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Act.
