                                                    Copenhagen, 21st March, 2007


Resume: The plant biotech company Aresa has been granted patents in South Africa
and in Singapore on the system behind the landmine detecting plant, RedDetect™. 


Patent grant.                                                                   

Aresa has today received notification that the patent authorities in South      
Africa and in Singapore has granted a patent in respect of “Reporter system for 
plants”, patent No. 2004/9782 in South Africa and patent No. 108113 in          
Singapore.                                                                      

The patent covers the system behind the landmine detecting plant, RedDetect™, as
well as detection and remediation of pollutants in soil.                        

The patent abstract is as follows:                                              

”A reporter system capable of giving rise to a directly monitorable phenotypic  
trait in a plant, in the presence of an outer stimulus such as for example a    
pollutant, is provided. The system optionally also has the ability to remediate 
soil. Genetically modified plants comprising said reporter system and optionally
the remediation capability, a process for detection of soil pollution and       
optionally for bioremediating soil by employing said genetically modified       
plants, as well as the use of genetically modified plants for monitoring soil   
pollution and optionally for bioremediating soil are also provided.”            

“The granting of these patents is yet another verification of the strength of   
the technology behind the landmine detecting plant, RedDetect™”, says Chief     
Scientific Officer and Founder of Aresa, Carsten Meier.                         


Best regards,
