(d)The Purchaser understands that the exemption from registration afforded by Rule 144 promulgated under the Securities Act (“Rule 144”) (the provisions of which are known to the Purchaser) depends on the satisfaction of various conditions, and that, if applicable, Rule 144 may afford the basis for sales only in limited amounts.

(e)The Purchaser did not employ any broker or finder in connection with the transactions contemplated in this Agreement and no fees or commissions are payable to the Purchaser, except as otherwise expressly provided for in this Agreement.

company” or (ii) does not have, and for so long as it holds any Series A Preferred Shares, will not have, “significant equity participation” by benefit plan investors. The term “venture capital operating company” has the meaning assigned to such term in the Department of Labor Regulation Section 2510.3-101.

(h)The Purchaser has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Series A Preferred Shares and has so evaluated the merits and risks of such investment. The Purchaser understands that it must bear the economic risk of its investment in the Series A Preferred Shares indefinitely and is able to bear such risk and is able to afford a complete loss of such investment.

(i)The Purchaser acknowledges that it has reviewed all materials the Purchaser deemed necessary for the purpose of making an investment decision with respect to the Series A Preferred Shares, including information regarding the Transactions, and the Purchaser has evaluated the risks of investing in the Series A Preferred Shares and understands there are substantial risks of loss incidental to the investment and has determined that it is a suitable investment for the Purchaser.
