investigations of law as we deemed appropriate for rendering the opinions expressed below. As to various questions of fact material to the opinions, we have relied, to the extent we deem appropriate, upon representations or certificates of officers or directors of the Company and upon documents, records and instruments furnished to us by the Company, without independently checking or verifying the accuracy of such documents, records and instruments.

We have assumed that (1) the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and will comply with all applicable laws; (2) a prospectus supplement, if required, will have been prepared and filed with the Commission describing the Shares offered thereby; (3) all Shares will be issued and sold in compliance with applicable securities laws and in the manner stated in the Registration Statement and any applicable prospectus supplement; (4) a definitive purchase, underwriting or similar agreement with respect to any Shares offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; and (5) there will be sufficient number of Shares authorized under the Company’s Articles of Incorporation that are not otherwise reserved for issuance.

Based upon and subject to the foregoing, we are of the opinion that:

(1) the Company Shares, when issued under the circumstances described in the Registration Statement, will be duly authorized, validly issued, fully paid and non-assessable at such time as (a) the Board of Directors of the Company, or a committee duly authorized by the Board of Directors, will have adopted appropriate resolutions to authorize the issuance and sale of the Company Shares and (b) the Company Shares will have been issued and sold by the Company for the consideration contemplated by, and otherwise in conformity with, the Registration Statement, as supplemented by a prospectus supplement, with respect to the issuance and sale of the Company Shares; and

This opinion is strictly limited to the matters stated herein and no other or more extensive opinion is intended, implied or to be inferred beyond the matters expressly stated herein.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement.
