                         ("Nighthawk" or the "Company") 
  Report on Continuity of Atoka and Cherokee Shales on the Jolly Ranch Acreage 
The directors of Nighthawk, the US focused hydrocarbon development and 
production company (Tickers: AIM: HAWK and OTCQX: NHEGY), are pleased to 
announce details of a report completed by Schlumberger Data & Consulting 
Services ("Schlumberger") in respect of the continuity of the Atoka and Cherokee 
Shales over certain key areas of the Jolly Ranch project acreage. 
The report was commissioned to confirm independently that the organic rich 
shales in the Atoka and Cherokee are laterally continuous, specifically between 
the Craig 6-4 SWD well and the recently drilled John Craig 7-2 well which are 
approximately 30 miles apart. 
Two north-south cross sections were constructed over the project acreage in the 
Jolly and Craig Ranch areas.  The stratigraphic tops were extended from the 
Jolly Ranch area approximately 30 miles to the north through the location of the 
recently drilled John Craig 7-2 well. 
The report concluded that in both the Atoka and Cherokee formations, the 
individual shales can be readily correlated through the area covered by the 
cross sections.  In addition, it was concluded that the result provides 
confidence that shales are present under most, if not all of Nighthawk's 
acreage. 
Details of the cross sections can be viewed on Nighthawk's website at

This report is independent of an ongoing Updated Evaluation of Hydrocarbons in 
Place and Reservoir Simulation report by Schlumberger, which is expected to be 
completed by Q4 2010. 
Tim Heeley B.Eng (Hons) a member of the Society of Petroleum Engineers, Fellow 
of the Geological Society of London and a Chartered Energy Engineer, who is 
Commercial Director of Nighthawk and has over 13 years of experience in the 
hydrocarbons industry, has approved the technical information contained in this 
announcement.
