Notes to Editors:

Northern Petroleum Plc is an AIM listed oil and gas production, development and exploration company with core interests under its management in The Netherlands, Italy and the United Kingdom.

Northern is currently embarked upon a programme to place two oil fields and four gas fields into production with works on the first two, Ottoland and Brakel starting in March and April 2007.

The Company has recently acquired the management interests in the producing Waalwijk gas field where it intends to implement plans to increase late phase gas, production and move to develop a 30 Bcf underground gas storage facility alongside Star Energy and Essent. The NPN deal with Dyas is the second gas production acquisition in 2007 to date.

Northern's Netherland partner list is impressive.

The Company has the second largest exploration position in Italy of licences under management where activities can be expected to pick-up as the result of the extra funds now available. In addition the Company has announced plans to drill a projected eastward extension of the producing Horndean oil field in West Sussex and another exploration well in the county.
