ARTICLE II

ACKNOWLEDGEMENTS OF THE PURCHASER

The Purchaser acknowledges the following:

2.1   NO REGISTRATION. The shares of Common Stock offered hereby have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state, and are being offered and sold in reliance on exemptions from the registration requirements of the Securities Act and state securities laws. The shares of Common Stock offered hereby have not been approved or disapproved by the Securities and Exchange Commission or the securities regulatory agency of any state, nor have any of the foregoing authorities passed upon or endorsed the merits of this offering. The shares of Common Stock offered hereby may not be sold, transferred, or otherwise disposed of except in compliance with applicable securities laws and other laws governing the offer and sale of such shares.

2.2   RESTRICTIONS, INFORMATION. Purchaser agrees that he will not sell or otherwise transfer the Purchaser’s Purchased Shares unless they are registered or exempt from registration under the Securities Act. It is understood that all documents, records, and books pertaining to this investment have been made available for inspection by the Purchaser.

2.3   ECONOMIC RISK. Because the Purchased Shares have not been registered under the Securities Act, or certain applicable state securities laws, the economic risk of the investment must be borne by the Purchaser and the Purchased Shares cannot be sold unless subsequently registered under the Securities Act and such state securities laws, or unless an exemption from such registration is available.
