The shares of Common Stock issued in the exchange were issued pursuant to an exemption from registration under Regulation D of the Securities Act of 1933, as amended, and therefore are "restricted securities."

Under the terms of the Series D exchange, the Series D Holders are generally not permitted to sell or transfer the Common Stock for three years from issuance. However, the restriction may be lifted earlier if an ownership change occurs which results in the loss of the Company's existing net operating loss carryforwards ("NOLs") or if the board of directors determines that the Company's NOLs will not be realized in whole or in part.
