Hyperdynamics Notified of DOJ Investigation

HOUSTON, Sept. 30, 2013

In 2006, a Production Sharing Contract was signed by the Company and the government of Guinea granting rights to an oil and gas concession offshore Guinea.  The Company understands that the DOJ is investigating whether Hyperdynamics' activities in obtaining and retaining the concession rights and its relationships with charitable organizations potentially violate the U.S. Foreign Corrupt Practices Act or U.S. anti-money laundering statutes.  The Company has retained legal counsel to represent it in this matter and is cooperating fully with the government.  The Company is unable to predict when the investigation will be completed, what outcome may result and what costs the Company will incur in the course of the investigation.
