| Re: | Registration Statement on Form S-3 Filed by ZBB Energy Corporation |
Ladies and Gentlemen:
We have acted as counsel to ZBB Energy Corporation, a Wisconsin corporation (the “Company”), in connection with the issuance of 800,000 shares of common stock of the Company, $0.01 par value per share (the “Securities”), pursuant to the terms of that certain Asset Purchase Agreement (the “Purchase Agreement”) dated as of January 21, 2011 among Tier Electronics LLC (f/k/a DCDC Acquisition Company LLC), TE Holdings Group, LLC (f/k/a Tier Electronics LLC), Jeffrey Reichard and the Company in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). In accordance with the Securities Act, and the rules and regulations of the Securities and Exchange Commission (the “Commission”) promulgated thereunder, the Company initially filed with the Commission a Registration Statement on Form S-3 (the “Registration Statement”) on January 31, 2011 relating to, among other things, the potential resale of the Securities.
In our capacity as counsel to the Company in connection with the registration for resale of the Securities, we have examined: (i) the Registration Statement; (ii) the Company’s Articles of Incorporation, as amended, and Amended and Restated By-Laws; (iii) the Purchase Agreement; (iv) certain resolutions of the Corporation’s Board of Directors; (v) certain corporate documents and records, certificates of public officials and certificates of officers of the Corporation; and (vi) such other proceedings, documents and records as we have deemed necessary or advisable for purposes of this opinion.
In all such investigations and examinations, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of original and certified documents and the conformity to original or certified documents of all copies submitted to us as conformed or reproduction copies.
Based on the foregoing and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that the Securities have been duly authorized, validly issued, fully paid and non-assessable.
