LUKOIL IS OFFERED TO ACQUIRE 20% IN THE JOINT VENTURE TO OPERATE ISAB

This is a partial exercise of ERG’s option to sell its stake according to the agreement of 2008 to create a joint venture.

Thus, LUKOIL’s stake in the joint venture can be increased from 60% to 80%.

The transaction closing is expected in the second quarter of 2012. The transaction amount will reach EUR 400 million, excluding inventory.
