Business Acquisition Intent For Debt Description

In January 2013, the Company and 0947388 BC Ltd. ("094") entered into a letter of intent for 094 to farm into the Edwards formation assets acquired through its acquisition of Pan American Oil Company, LLC (see Note 2) and Numa Luling, LLC (see Note 4) and also the 80% interest in certain leasehold interests acquired from Eagle Ford Oil Co., Inc. (see Note 4). The letter of intent specifies that upon completion of the #4H Tiller well currently being completed by the Company, 094 will drill 10 wells within the Edwards formation of which 100% of the costs shall be borne by 094. At the end of the 10 well program, 094 has the option to extend the program for a further 5 wells, borne at the sole cost of 094 or acquire 100% of the Company's interest in the Edwards formation leasehold interests for $45 million, which price is reduced on a pro rata basis should oil prices drop below $85 per barrel down to a minimum of $30 million. Should 094 decide not to purchase 100% of the Company's interest in the Edwards formation leasehold interests, then 094 will earn 80% of revenue from those 10 wells drilled by 094 until such time as it has recouped its costs, at which point its revenue interest reverts to 60%. In addition, 094 will also drill 5 wells within the Buda formation at its sole costs. At completion, 094 has the option to acquire 30% of the interest held by the Company in the entire leasehold through payment of $7.5 million to the Company. In the event 094 chooses not pay the final option price it will earn only a 30% interest in the 5 wells drilled by 094. At the time of entering the letter of intent, 094 paid a refundable deposit of $300,000. The Company and 094 are still in negotiations and no agreement has been finalized.
