SOUTHERN ALBERTA BASIN

Rosettas 11-well vertical drilling program to assess the commerciality of the play across its approximately 300,000-acre position in northwest Montana is nearing completion.

The Company had two rigs under contract during the quarter. As of March 31, 2011, eight vertical delineation wells had been drilled with operations underway on the ninth and tenth vertical wells.

During the second quarter of 2011, one additional vertical well is planned. Based on encouraging vertical well results, Rosetta will spud the first of three horizontal wells in the second quarter.

We hope you find this update informative.
