	i.	exercise a Put Option to transfer an additional 10% PI to BP in exchange for a full carry on Eco's remaining 15% PI subject to a cap of US$21 million net to Eco for each well on each of the licenses (PEL97, PEL99, and PEL100); or
	ii.	elect to retain its 25% PI of the costs associated with such drilling of a well during the Second Renewal Period.
•	The maximum aggregate Carry consideration payable by BP in respect of each Put Option (should all Put Options namely on PEL97, PEL99, and PEL100 be exercised) is US$63 million with a cap of US$21 million per Put Option.
•	Eco can elect to retain its 25% paying interest and/or to farm out to other potential partners (subject to such partners meeting technical and financial qualifications)

Gil Holzman, President and Chief Executive Officer of Eco Atlantic, commented:

“Securing final regulatory approval for the farm down of our Namibian portfolio to BP is a significant milestone for Eco and brings us towards completing this landmark transaction.

“We are grateful to Her Excellency the President of the Republic of Namibia and the Namibian authorities, particularly the Ministry of Industries, Mines and Energy and the Upstream Petroleum Unit, for their efficient, professional and collaborative approach, which enabled the approval process to progress within the anticipated timeframe. We also thank BP, NAMCOR and our local partners for their continued cooperation and support throughout the process.

“With final regulatory approval now secured, we will complete the remaining closing formalities as swiftly as possible and look forward to moving full steam ahead with BP, NAMCOR and our local partners into the next phase of exploration across these highly prospective Walvis Basin licences.

“With our significant South Africa and Namibia transactions now successfully progressed, our focus turns to delivering the remaining key milestones across the portfolio, including finalising our PSA negotiations in Guyana and completing the JHI acquisition announced earlier this year.”
