So long as any Investor holds Shares, if any governmental agency in the Peoples Republic of China takes any action that materially and adversely affects the transactions contemplated by the Amended Turnkey Agreement or that certain Rescission, Termination and Share Exchange Agreement, dated on or about the Closing Date, among iASPEC, Bo Hai Wen, the shareholders of iASPEC, China Public Security Holdings Limited and the Company, and the Company can not undo such governmental action or otherwise address the material adverse effect to the reasonable satisfaction of the Investors within sixty (60) days of the occurrence of such governmental action, then, upon written demand from an Investor, the Company shall promptly, and in any event within thirty (30) days from the date of such written demand, pay to that Investor, as liquidated damages, an amount equal to that Investor’s entire Investment Amount without interest thereon. As a condition to the receipt of such payment, the Investor shall return to the Company for cancellation the certificates evidencing the Shares acquired by the Investor under the Agreement.”
