                                and Abandonment


The Company announces that an unsuccessful well test has been conducted in the
ERB-B-1X well operated by Apache East Ras Budran Corp. LDC ('Apache') in the
East Ras Budran ('ERB') Concession in which Regal holds a 25% working interest.

The well was spudded on 7 October 2007 and drilled to a total depth of 5,146
feet in basement, several zones in the well had oil shows and the well was
subsequently tested without a productive flow of oil being achieved. The well is
now being plugged and abandoned.

The ERB-B-1X well is the second of two commitment wells in the initial
exploration period of the ERB Concession. An additional exploration well,
ERB-B-2X, is now under consideration to be drilled in late 2007 if a suitable
drilling rig can be mobilised to the area.
