ERRINGTON-1: EXPLORATION WELL, PEDL 028, ONSHORE UK (ROC: 100% & Operator)

As at 21 November 2004, the ROC-owned Explorer Rig had been rigged-up at the
Errington-1 exploration wildcat well site and preparations were underway to
commence conventional petroleum drilling activities following the release of the
air drilling rig which had been used to drill the top hole section.

Errington-1 is located in PEDL 028 approximately 35 km west of Newcastle in
northern England.

The Errington-1 wildcat exploration well, which is targeting a potentially large
gas prospect, is expected to reach the first objective horizon during the latter
part of December 2004.
