Based upon, subject to and limited by the foregoing, we are of the opinion that following (i) execution and delivery by the Company and each of the Investors of the Agreement, (ii) effectiveness of the Registration Statement, (iii) issuance of the Securities pursuant to the terms of the Agreement and/or in the manner described in the Registration Statement, and (iv) receipt by the Company of the consideration for the Securities specified in the Resolutions:
