Heerlen, NL, 28 Apr 2011 19:16 CEST

The DSM Annual General Meeting of Shareholders on 28 April 2011 passed a resolution to declare a dividend for 2010 of €1.35 per ordinary share of €1.50 par value. An interim dividend of €0.40 per ordinary share having been paid on 27 August 2010, the final dividend for 2010 will amount to €0.95 per ordinary share.

This final dividend of €0.95 will be paid out in cash or in the form of ordinary shares at the option of the shareholder. Dividend in cash will be paid after deduction of 15% Dutch dividend withholding tax. The ex-dividend date on NYSE Euronext will be 2 May 2011 and the record date will be 4 May 2011.

Shareholders have from 5 May until 20 May 2011 (15.00 CET) to indicate their choice. On 20 May 2011 after the close of trading on NYSE Euronext the number of dividend rights of ordinary shares entitling the holder to one ordinary share will be determined.

This exchange ratio will be based on the volume weighted average price of all ordinary shares in DSM traded at NYSE Euronext on 16, 17, 18, 19 and 20 May 2011. The value of the stock dividend will be virtually equal to the value of the cash dividend. The ordinary shares that constitute the stock dividend are entitled to any dividend for the financial year 2011 and to the dividends for subsequent financial years. Stock dividend rights will not be traded on NYSE Euronext.
