The well intersected gas in the target sands confirming hydrocarbons in the
eastern region of the Frankland Field. The top of the reservoir was encountered
deep to prognosis and the gas column was thicker than prognosed but the
reservoir is of poorer quality than that encountered in Frankland-1. The
Frankland-2 well is currently being plugged and abandoned.

and in conjunction with the results of the 3D seismic survey currently being
processed, the field will be re-evaluated for possible further appraisal.

Frankland-2 is approximately one kilometre northeast of the 2007 Frankland-1
well gas discovery.

Following the drilling of Frankland-2, ROC and the Joint Venture plan to drill
the Dunsborough-2 well which will appraise the 2007 Dunsborough oil discovery.
