DKK 1.0 billion, from Novo A/S as part of the ongoing DKK 17.5 billion share
repurchase programme for 2006-2009. The transaction price is DKK 307.37 per

August in the open trading window following the announcement of Novo Nordisk's
financial results for the first six months of 2008.

Novo A/S has hereby re-adjusted its ownership of Novo Nordisk A/S to 25.5%,
equal to the level of ownership prior to the cancellation of treasury shares,
which took place in June 2008.

The total shareholding of Novo A/S in Novo Nordisk A/S prior to the sale of B
shares was 107,487,200 A shares (nominal DKK 1) and 57,487,600 B shares (nominal
DKK 1), corresponding to 26.0% of the share capital and 70.7% of votes. The
current transaction reduces Novo A/S' ownership of Novo Nordisk A/S to 25.5% of
capital and 70.5% of votes.

Henrik Gurtler, CEO of Novo A/S, said: "Following the recent cancellation of
treasury shares Novo A/S has re-aligned its shareholding in Novo Nordisk A/S to
the level of just over 25%, which has been our target since the demerger of
Novozymes A/S in 2000. We remain a committed long-term majority shareholder of
Novo Nordisk."

As of 14 August 2008, Novo Nordisk has repurchased B shares amounting to DKK 3.0
billion in 2008. Novo Nordisk A/S and its wholly-owned affiliates now own
21,264,030 of its own B shares of DKK 1, corresponding to a total nominal value
of DKK 21,264,030 or 3.35% of the total share capital.
