The Linden gas discovery drilled by Elf Aquitaine in 1972 tested gas despite well control difficulties that resulted in considerable damage to the reservoir and compromised the flow rates achieved.  In April 2010 Ascent sold its 100% owned Swiss subsidiary, PEOS AG ('PEOS'), to eCORP Europe International Ltd. ('eCORP'), for a cash consideration of €8 million, together with vaious farm-in options on certain potentially successful discoveries.

Ascent retains the right to acquire 45% of any conventional discovery from the Linden-2 appraisal well by paying 45% of drilling costs post any discovery with no obligation to participate.

Ascent retains the right to 22.5% of any discovery from certain additional conventional prospects by paying 22.5% of the drilling costs post discovery, again with no obligation to participate.
