"Enovation will hold a 10% participating interest together with its joint venture operating partner Neon Energy Limited who holds the remaining 90% interest in the block.

The Production Sharing Contract between Enovation and Petrovietnam, on behalf of the Government, was signed on 5th January 2010 in Hanoi. The Block 105-110/04 Production Sharing Contract has an initial term of 4 years during which time Enovation is obligated to acquire 2D seismic data and drill at least one exploration well."
