SUGAR LAND, Texas, Dec. 14 /PRNewswire-FirstCall/ -- Hyperdynamics Corporation (NYSE Amex: HDY) today announced the retirement of its remaining long-term debt after completion of its previously announced registered direct offering of 7.2 million shares of common stock and warrants to purchase 3.25 million shares of common stock which provided $6.5 million in gross proceeds. Of this amount, $525,000 has been used to retire all of the Company's outstanding convertible debentures. As a result, Hyperdynamics has no long-term debt remaining on its balance sheet.
