NOVO NORDISK A/S PURCHASES B SHARES WORTH DKK 643 MILLION FROM NOVO A/S AS PART
OF THE ONGOING SHARE REPURCHASE PROGRAMME

NOVO NORDISK A/S HAS TODAY ACQUIRED 2,150,000 B SHARES, WORTH DKK 643 MILLION,
FROM NOVO A/S AS PART OF THE ONGOING DKK 5 BILLION SHARE REPURCHASE PROGRAMME.
THE TRANSACTION PRICE IS DKK 299 PER SHARE AND HAS BEEN CALCULATED AS THE
AVERAGE MARKET PRICE IN THE OPEN WINDOW PERIOD 28 OCTOBER TO 11 NOVEMBER 2004,
FOLLOWING THE ANNOUNCEMENT OF THE FINANCIAL RESULT FOR THE FIRST NINE MONTHS OF
2004.

As a result of Novo Nordisk's cancellation of DKK 45 million of treasury B
shares in August 2001, Novo A/S has seen an increase in its ownership of Novo
Nordisk A/S from slightly more than 25% following the demerger of Novozymes in
2000 to around 27%. Novo A/S' shareholding in Novo Nordisk A/S prior to the sale
of B shares was 53,743,600 A shares (nominal DKK 2) and 40,992,780 B shares
(nominal DKK 2), corresponding to 26.7% of capital and 70.6% of votes. The
current transaction reduces Novo A/S' ownership of Novo Nordisk A/S to 26.1% of
capital and 70.6% of votes. Furthermore, Novo A/S has communicated its intention
of reducing its ownership of Novo Nordisk A/S to the long-term target level of
slightly more than 25% of the capital during 2005.

Henrik Gurtler, CEO of Novo A/S, said: "By re-aligning our shareholding in Novo
Nordisk A/S to the previous level, our ability to diversify our portfolio is
increased. We remain a committed long-term controlling shareholder of Novo
Nordisk and we expect to maintain our ownership slightly above 25% of the
capital."

As of 12 November, Novo Nordisk has repurchased B shares amounting to around DKK
1.7 billion and still expects to repurchase B shares worth some DKK 2 billion in
2004 as part of the ongoing share repurchase programme. Novo Nordisk A/S and its
wholly-owned affiliates now own 21,796,047 of its own B shares of DKK 2,
corresponding to a total nominal value of DKK 43,592,094 or 6.15% of the total
share capital.
