For the three months ended March 31, 2013, Donnybrook’s three Bigstone wells
produced intermittently for the equivalent of approximately
29 days out of the 90 day period due in part to third party facility and pipeline
maintenance which required the wells to be shut-in. Total net production
to Donnybrook during the period was approximately 4,522 boe.

Donnybrook has a 50% working interest drilling location surveyed on the west side of its acreage block for an extended reach horizontal well. Timing to drill this location will be predicated on further evaluation of the Company’s current production at Bigstone and results from offsetting wells being drilled by industry competitors.
