Copenhagen, Denmark; June 04, 2008 – Genmab A/S (OMX: GEN) announced today that on a board meeting the board decided to issue 231,500 warrants to employees of the company as well as the company’s subsidiaries and to a member of the management. No members of the company’s board granted warrants.

The exercise price for each warrant is DKK 246.00. Each warrant entitles the owner to subscribe one share of nominally DKK 1. On the basis of an exercise price of DKK 246.00 and by application of the Black-Scholes formula, the average value of each warrant can be calculated as DKK 78.93 based on an interest rate of 4.28% and the historical volatility of Genmab A/S shares calculated at 25.21%.

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.
