Seismic Program

• Primary has completed five 3D seismic programs covering approx.
  
  95 sq.
  
  miles and one additional 37 sq.
  
  mile program is currently being permitted.
  
  

Initial Six Vertical Stratigraphic Wells:

• All six wells were drilled vertically into the upper Duperow formation, ranging in depth between 4500 -6500 ft.
  
  All wells were cored across various sections of the �Bakken System� (lower Lodgepole, Bakken, Three Forks and Big Valley/Upper Potlatch).
  
  
  • Oil and gas shows were identified on logs in multiple reservoir zones in all wells.
    
    
  • Free oil was observed in one or more of the cores.
    
    
• Standard log suites were acquired in all wells and advanced log suites were acquired in five of the wells.
  
  
• Two wells were cased, perforated and swab tested in the Bakken System and/or secondary zones, with fluid samples currently being analyzed.
  
  
• Routine core analysis has been completed on four of the six wells to-date.
  
  Porosity up to 10.4% and non-fractured permeability up to 0.3mD (millidarcy) have been reported.
  
  
• Geochemical analyses have been completed on select samples with additional analysis in progress.
  
  Sample analyses indicate a thermally mature Bakken System source rock in the oil window, with some zones where TOC (total organic content) reaches up to 17%.
  
  
• Special core analysis for the horizontal drilling program has been completed on select samples, with additional analysis in progress.
  

Three Supplemental Vertical Wells:

• All wells drilled into the upper Duperow formation, with one well cored across the Nisku formation.

  The Company is also anticipating the conclusion of completion operations by the end of October.
