HOUSTON, Aug. 5, 2013 /PRNewswire/ --Hyperdynamics Corporation (NYSE: HDY)
announced today that Tullow Oil Guinea Ltd. has formally notified the Republic
of Guinea, on behalf of the consortium that is exploring for oil offshore
Guinea, of its intent to elect to extend the Second Exploration Period for an
additional three years, as provided for under the terms of its existing
Production Sharing Contract (PSC).

During the three-year extension of the Second Exploration Period – which
extends through September 21, 2016 – the consortium will be required to drill
one exploration well to a minimum depth of 2,500 meters below the seabed.
Tullow Oil, the concession's operator, plans to spud the next exploration well
– a deep water fan prospect – in the first quarter of 2014. Also, as part of
the requirements under the PSC, the consortium will relinquish 25 percent of
the remaining concession area back to the government of Guinea on September
21, 2013.

"This three-year renewal is a key step in advancing our ongoing exploration
program offshore Guinea," said Ray Leonard, President and Chief Executive
Officer of Hyperdynamics. "As the new operator, Tullow is making strong
progress in leading the development of our work plan for the next exploration
well. Tullow has committed to the project a high-quality deep water drilling
rig, and we look forward to testing a high-potential deepwater prospect
offshore Guinea sometime early next year," he added.

Hyperdynamics holds a 37 percent non-operated working interest in the offshore
Guinea exploration project. Tullow Oil, the operator, holds a 40 percent
working interest, and Dana Petroleum holds a 23 percent working interest.
