San Leon Energy is pleased to announce that it has accepted a cash offer of €9.9 million (approx.

The Offer will complete by 20 July 2012.

Oisin Fanning, Chairman of San Leon, commented:

"We are pleased to accept this offer from GDF Suez. Considering the international risks facing oil prices, we consider the offer to represent fair value. These resources can now be applied to San Leon's other core exploration activities, such as in Poland, where we are planning further exploration on the back of the Siciny-2 well success*."
