As consideration for termination of the Financing Documents and the Security Agreement, and pursuant to the terms thereunder, the Company shall issue to the Lender 244,736,130 shares of common stock of the Company (the "Shares"), without giving effect to the Company's proposed one (1) for thirty (30) reverse stock split.

The Lender understands that the Shares are unregistered and, may be required to be held unless they are subsequently registered under the Securities Act, or an exemption from such registration is available. Lender acknowledges that one such exemption from registration which permits sales to the public is Rule 144 under the Securities Act which requires that the securities be held for a minimum of one year and has certain restrictions on the manner of sale and that the Company is not current with respect to its obligations to file the periodic reports required under the Securities Exchange Act of 1934 during the past 12 months.
