Formal Notice

Novo Nordisk stock split information

As communicated on 3 August 2007 in connection with the release of Novo
Nordisk's financial results for the first six months of 2007, Novo Nordisk's
Board of Directors has approved a stock split of the Novo Nordisk B shares
listed on the OMX Nordic Exchange and the London Stock Exchange as well as of
the American Depositary Receipts (ADRs) listed on the New York Stock Exchange
(NYSE). The trading unit of the Novo Nordisk B shares listed on the stock
exchanges in Copenhagen and London will be changed from DKK 2 to DKK 1. The
ratio of B shares to ADRs listed on the NYSE will remain 1:1. These changes in
trading units will take effect as of 3 December 2007 for the Novo Nordisk B
shares and as of 17 December for the ADRs.

Further details on the stock split

On 3 December 2007, the Novo Nordisk A/S B shares traded on the OMX Nordic
Exchange and on the London Stock Exchange will be split into two shares. The
last day of trading in the old shares will be 30 November 2007 and the first day
of trading in the new shares will be 3 December 2007. The record date is 30
November 2007.

On 17 December 2007, each of Novo Nordisk's ADRs listed on the NYSE will also be
split. On 20 December, new ADRs will be distributed in the proportion of one
additional ADR per existing ADR to ADR holders of record as of 30 November.

Hence, the ratio of B shares to ADRs listed on the NYSE will remain 1:1. The new
shares issued due to the split will be of the same type and class as the
original shares.

Due to operational reasons, from 3 December through 16 December 2007, the Novo
Nordisk B shares listed on the stock exchanges in Copenhagen and London will be
traded post-split whereas the ADRs listed on the NYSE will be traded pre-split.
Post-split trading on the NYSE will start on 17 December 2007.

JPMorgan, the depositary bank of Novo Nordisk's ADRs, will not execute issuances
and/or cancellations of ADRs between close of business 29 November and close of
business 19 December 2007. However, the trading of Novo Nordisk's ADRs on the
NYSE will continue as normal.
