Copenhagen, Denmark; June 18, 2009 - Genmab A/S (OMX: GEN) announced today that 
on a board meeting on June 17, 2009 the board decided to issue 337.000 warrants 
to members of the board of directors, managers and employees of the company as  
well as the company's subsidiaries.                                             
                                                                                
The exercise price for each warrant is DKK 174.00. Each warrant entitles the    
owner to subscribe one share of nominally DKK 1. On the basis of an exercise    
price of DKK 174.00 and by application of the Black-Scholes formula, the average
value of each warrant can be calculated as DKK 79.19 based on an interest rate  
of 2.85% and the historical volatility of Genmab A/S shares calculated at       
47.12%.                                                                         
                                                                                
The warrants vest in blocks of 25% one, two, three and four years after the     
grant date, and all warrants expire at the tenth anniversary of the grant date. 
The new warrants were granted pursuant to the warrant plan adopted by the board 
on August 3, 2004. Information concerning Genmab's warrant schemes can be found
