The Purchaser acknowledges that because the Company was previously a "shell" company as defined in Rule 144, the safe harbor provided by Rule 144 will only be available to the Purchaser at such times as the Company is current in all of its reporting obligations under the Securities Exchange Act of 1934, as amended. Although the Company is current in the filing of such reports as of the date hereof, the Purchaser acknowledges that the Company cannot assure the Purchaser that the Company will remain in compliance.

(c) Compliance With Securities Laws. The Purchaser understands and agrees that because the Securities are being acquired under Regulation S and are “restricted securities,” The Purchaser will be required to comply with both the provisions of Regulation S and Rule 144 in any resale of the Common Stock, absent registration of the Common Stock or an exemption therefrom.
