Copenhagen, Denmark; December 13, 2007 – Genmab A/S (OMX: GEN) announced today that on a board meeting the board decided to issue 132,030 warrants to employees of the company as well as the company’s subsidiaries. No members of the company’s board or management were granted warrants.

The exercise price for each warrant is DKK 329. Each warrant entitles the owner to subscribe one share of nominally DKK 1. On the basis of an exercise price of DKK 329 and by application of the Black-Scholes formula, the average value of each warrant can be calculated as DKK 138.20 based on an interest rate of 4.09% and the historical volatility of Genmab A/S shares calculated at 39.41%.

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.
