                             STOCK EXCHANGE RELEASE

                   ACTIVITY UPDATE: PRODUCTION & EXPLORATION

1.  PRODUCTION

1.1 Enoch Oil and Gas Field, North Sea, UK (ROC: 12%)

ROC's wholly-owned subsidiary, Roc Oil (GB) Limited, is pleased to advise that
the Enoch Oil and Gas Field started production on Thursday 31 May 2007, UK time.
Early field production rates are expected to exceed 12,000 BOPD and 20 MMSCFD of
gas (Net ROC: 1,440 BOPD and 2.4 MMSCFD). Enoch production is transported to and
processed at, the Brae Alpha facility, some 15 km to the northwest.

The Talisman North Sea Limited operated unitised Enoch Oil & Gas Field is
located 250 kilometres northeast of Aberdeen and straddles the UK and Norwegian
international boundary.

Commenting on the start-up at Enoch, ROC's Chief Executive Officer, John Doran
stated that:

'Enoch represents another production box ticked, this time in the North Sea. As
a result, ROC's company-wide production has kicked back into the 10,000-12,000
BOPD range. When the Blane Field starts producing later this year about 25% of
ROC's production will come from the North Sea.'

1.2 Cliff Head Oil Field, Offshore Western Australia (ROC: 37.5% & Operator)

Recent well workover operations at the Cliff Head Oil Field have been completed,
as a result of which, current reservoir production capacity is estimated to be
comfortably above 10,000 BOPD. Actual gross production is approximately 9,500
BOPD (Net ROC: 3,375 BOPD) which reflects a current trucking constraint.

1.3 Zhao Dong C & D Oil Fields, Bohai Bay, Offshore China (ROC: 24.5% &
    Operator)

Gross daily oil production from the Zhao Dong C & D Oil Fields averaged
approximately 20,000 BOPD (Net ROC: 5,000 BOPD) during May. The development
drilling activities which commenced in April will result in an additional 9
producers and 6 water injectors being drilled and this is expected to lift
field-wide production to approximately 25,000 BOPD.

1.4 Chinguetti Oil Field, Offshore Mauritania (ROC: 3.25%)

During May, the Chinguetti Oil Field produced at a gross rate of approximately
17,600 BOPD (Net ROC: 572 BOPD) from six wells, including the recently completed
infill development well.

2.  EXPLORATION

2.1 Dunsborough-1, Perth Basin, Offshore Western Australia (ROC: 37.5% &
    Operator)

Roc Oil (WA) Pty Limited advises that the Dunsborough-1 exploration well
commenced drilling operations at 1730 hours Australian Western Standard Time
(AWST), on 31 May 2007. As of 0600 hours (AWST) on 1 June, the current operation
was installing 508 mm conductor at 101mBRT.

Dunsborough-1, the final well in a series of three exploration wells in the
northern part of the offshore Perth Basin, is being drilled by the Premium
'Wilcraft' jack-up drilling rig. The well is located in exploration permit
WA-286-P, approximately 25 km northwest of the recent Frankland-1 gas discovery.

2.2 Massambala-1, Cabinda South Block, Angola (ROC 60% & Operator)

Road access and site preparation have been completed at the Massambala-1
location following heavy unseasonal rain during the last two weeks which delayed
construction. Massambala-1 will be drilled by the ROC Explorer drilling rig and
is expected to commence within two weeks.

Refurbishment of the 'Simmons 80' rig in Dubai is almost complete and the rig is
expected to be ready to commence drilling in Angola during July.
