This letter is furnished to you at your request and in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”).

In connection with this letter, we have examined and relied upon originals or copies of: (1) the Registration Statement; (2) the Merger Agreement; (3) the Company’s Articles of Incorporation, as amended to date; (4) the Company’s Bylaws, as amended to date; (5) resolutions of the Company’s Board of Directors pertaining to the Registration Statement, the Merger Agreement, the Outstanding Shares, the Additional Shares and related matters; and (6) such other corporate records and documents as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. We have also reviewed such matters of law as we considered necessary or appropriate as a basis for the opinion expressed below.

With your permission, we have made and relied upon the following assumptions, without any independent investigation or inquiry by us, and our opinion expressed below is subject to, and limited and qualified by the effect of, such assumptions: (1) all corporate records furnished to us by the Company are accurate and complete; (2) the Registration Statement to be filed by the Company with the Commission will be identical to the form of the document that we have reviewed; (3) all statements as to factual matters that are contained in the Registration Statement (including the exhibits to the Registration Statement) are accurate and complete; (4) the Company will issue the Additional Shares in accordance with the terms of the Merger Agreement; (5) the Company will at all times reserve a sufficient number of shares of its unissued Common Stock as is necessary to provide for the issuance of the Additional Shares; and (6) with respect to documents that we reviewed in connection with this letter, all documents submitted to us as originals are authentic; all documents submitted to us as certified, facsimile, or
