Dividends

Dividend amounts paid to shareholders resident in Canada are adjusted by the exchange rate applicable on the dividend record date. Dividends are normally paid in February, May, August and November, with record dates normally set approximately three weeks earlier. Future cash dividends will be paid out of, and are conditioned upon, the company's available earnings. Shareholders who wish to have their dividends deposited directly to their bank accounts should contact the transfer agent and registrar, CIBC Mellon Trust Company.

Registered shareholders can have dividends reinvested in newly issued common shares of PotashCorp at prevailing market rates.

Information for Shareholders Outside Canada

Dividends paid to residents in countries with which Canada has bilateral tax treaties are generally subject to the 15 percent Canadian non-resident withholding tax. Shareholders in the United States who have not filed a W-9 are also subject to the backup withholding tax (currently 28 percent). There is no Canadian tax on gains from the sale of shares (assuming ownership of less than 25 percent) or debt instruments of the company owned by non-residents not carrying on business in Canada. No government in Canada levies estate taxes or succession duties.
