Derivative transaction, conditions description   The purchase price is set at ninety-five percent (95%) of the volume weighted average price (VWAP) of the Common Stock during the one trading day immediately following our put notice. We have the right to withdraw all or any portion of any put, except that portion of the put that has already been sold to a third party, including any portion of a put that is below the minimum acceptable price set forth on the put notice, before the closing. In the event Dutchess receives more than a five percent (5%) return on the net sales for a specific put, Dutchess must remit such excess proceeds to us; however, in the event Dutchess receives less than a five percent (5%) return on the net sales for a specific put, Dutchess has the right to deduct from the proceeds of the put amount on the applicable closing date so Dutchess’s return will equal five percent (5%).
