Under the terms of the sale and purchase agreement, the Company is entitled to receive contingent future payments of USD5 million (subject to the purchaser making certain future elections with regards to the permit) and USD10 million for each 25 million barrels of oil equivalent in the event oil is produced from the permit area should the exploration well be a commercial success.

The wells could be drilled at any time within a 5-year window under this EP, commencing no earlier than 1 January 2025 and to be completed no later than 31 December 20295.
