2.  Representations by Subscriber. In consideration of the Company’s acceptance of participation,

I make the following representations and warranties and agreements to the Company, to its principals, and to participating broker-dealers, if any, jointly and severally, which warranties and representations and agreements shall survive any acceptance of my participation in the Shares:

(c) Subscriber has had an opportunity to inspect relevant documents relating to the organization and operations of the Company. Subscriber acknowledges that all documents, records and books pertaining to this investment which Subscriber has requested have been made available for inspection by Subscriber and Subscriber’s attorney, accountant or other adviser(s).

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “SECURITIES ACT”) OR UNDER APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AVAILABLE EXEMPTIONS FROM SUCH

REGISTRATION, PROVIDED THAT THE SELLER DELIVERS TO THE COMPANY AN OPINION OF COUNSEL (WHICH OPINION AND COUNSEL ARE REASONABLY SATISFACTORY TO THE COMPANY) CONFIRMING THE AVAILABILITY OF SUCH EXEMPTION.

(m) If Subscriber is a retirement plan or is investing on behalf of a retirement plan, Subscriber acknowledges that investment in the Common Shares poses risks in addition to those associated with other investments, including the inability to use losses generated by an investment in the Common Shares to offset taxable income.
