2 CUADRILLA RESOURCES LTD Cuadrilla Resources Limited ( Cuadrilla, CRL or the Company ) was formed in September 2007 as a privately held exploration and production company focused on bringing together leading unconventional oil and gas explorers, developers and technologists to unlock untapped unconventional resource plays in selected parts of Europe. The current focus of activity is the UK, Netherlands and Poland Cuadrilla is vertically integrated in order to control all aspects of its drilling and development programme. To this end, it has designed and overseen the manufacture and commissioning of a purpose built DrillMec HH220 top drive rig and state of the art cementing, fracture stimulation and completion equipment. All components of this equipment are designed for European specifications (noise, roads, etc.) and certified to both American and European standards. Cuadrilla has assembled a proven management team with multiple decades of experience in unconventional gas services and exploration/development Principle investors are Riverstone Europe LLP and A J Lucas Group

10 BOWLAND BASIN

11 Lower Carboniferous Extensional Basins in the UK The Bowland basin is one of a number of Lower Carboniferous extensional basins Compared to similar basins in the UK it has suffered deeper burial and greater inversion Main basin boundary faults have NE-SW orientation Basin is terminated to the NE by the Craven Fault System

12 (after Waters and Davies, 2009) UK Lower Carboniferous/Namurian Basins

13 Current Exploration Acreage in the UK- PEDL165

14 Bowland Basin and East Irish Sea Oil & Gas Province PEDL165 lies on the onshore flank of the East Irish Sea Basin Currently has one small producing gas field at Elswick Significant Shale Gas Potential in the Bowland Shale Fm and Namurian shales
