                         ROC OIL COMPANY LIMITED ('ROC')
                             STOCK EXCHANGE RELEASE

                    LATEST INVESTOR PRESENTATION APRIL 2006

Please note the following updates in the latest Investor Presentation:

•   Up to eight, compared with the previously reported 11 exploration wells
    are now expected to be drilled offshore Mauritania. This is partly due to a
    two month delay with the start of the 2006 drilling programme, which will
    now commence in July.

•   Jacala-1, offshore Western Australia, re-commenced drilling on 3 April
    2006 after operations were interrupted by cyclone activity and operational
    issues with the conductor. Drilling is expected to be completed during late
    April 2006.

•   The drilling of the Aleta prospect, offshore Equatorial Guinea,
    continues to be subject to securing a suitable rig contract and has shifted
    to December 2006 with the possibility that it could be delayed further to
    2007.

•   The drilling programme in Angola is now expected to start in October
    2006. This programme was previously reported as a stretch target for a mid
    September 2006 commencement.
