                             STOCK EXCHANGE RELEASE

        DRILLING UPDATE: LILAC-1 EXPLORATION WELL, OFFSHORE PERTH BASIN

Roc Oil (WA) Pty Limited, a wholly owned subsidiary of ROC, advises that since
its last Stock Exchange Release on 4 February 2008, the Lilac-1 exploration well
in WA-286-P, in the North Perth Basin, offshore Western Australia, has drilled
to a Total Depth of 1455 mBRT and wireline logging is underway.

The Lilac-1 exploration well encountered sands with weak gas shows and
fluorescence. However, preliminary interpretation of mud log, Logging While
Drilling (LWD) and drill data indicates that the primary reservoir is water
bearing. A final analysis will be made once wireline logging is completed. It is
expected that the well will be plugged and abandoned.

The forward programme for the Premium 'WilCraft' jack-up drilling rig is to move
to the second well of the current programme, Frankland-2, also in WA-286-P.
Frankland-2 will appraise a structure about one kilometre northeast of
Frankland-1 which discovered gas in 2007. Frankland-2 is expected to be
completed by the end of February 2008.

Participating Interests in the WA-286-P joint venture are:

Roc Oil (WA) Pty Limited.................................................. 37.5%
AWE Oil (Western Australia) Pty Ltd....................................... 27.5%
ARC Energy (Offshore PB) Limited.......................................... 30.0%
