• A few operators are actively pursuing the second white specs and a number of operators with significant land positions in the play fairways
• Evolved over past year from science and data from existing wells (well studies etc.) to new exploration and play definition
• First horizontal wells have been drilled with mixed results as people are trying to gain understanding of science
• New exploration and success with modern technology has allowed insight into petroleum system and importance of natural fractures
• Shale exploration has significant land position in the 2WS and over next year will be drilling exploration wells with our JV partner in our central Alberta holding and in our 100% southern Alberta land holdings based on understanding of the 2ws
