Re: Amendment to the Selling Agreement (the "Amendment")

Dear ▇▇. ▇▇▇▇▇▇▇:

This letter shall constitute a formal amendment to the Selling Agent Agreement executed between us on March 27, 2007. This will confirm our agreement as follows:

1.

On or before July 2, 2007, the Selling Agent shall agree to raise additional capital on behalf of the Company in the amount of $500,000.

2.

In consideration for the additional capital raise set forth in paragraph 1 above, the Company agrees to delete the third sentence of Section 1.3 of the Selling Agent Agreement and replace it with the following: Additionally, the Seller shall grant the Selling Agent 1,400,000 restricted shares of common stock of the Seller, of which 400,000 shares shall be delivered at the Initial Closing under the Selling Agreement and 1,000,000 shares shall be delivered by the Seller to the Selling Agent simultaneously with the closing of the fund raising set forth in Section 1 of this Amendment."

3.

All other provisions of the Selling Agent Agreement remain unchanged and are in full force and effect.

Very truly yours,

▇▇▇ ▇▇▇▇▇

CEO
