In order to complete the purchase of the first 20% interest in Seller’s Assets, Buyer shall make the Intermediate Payments in (E) below at which time such interest will be transferred to Buyer.

    (A)
Buyer has issued to Seller 1,895,000 common shares of Buyer and 1,612,000 warrants to purchase commons shares of Buyer for 24 months at a price of $0.75 per share (such shares and warrants held in escrow as security until “Acquisition Closing” when these shares and warrants will be exchanged for newly issued Pubco shares and warrants as detailed in (B) below);
       
    (B)
Buyer has entered into agreement with the publicly traded company U.S. Cobalt, Inc., (hereinafter referred to as “Pubco”) pursuant to which Pubco agrees to acquire all outstanding and issued shares and warrants of Buyer (the “Acquisition”).
