PotashCorp Acknowledges Premier's Statements / PotashCorp Shares Premier's Bright Outlook for the Company and Industry

SASKATOON, Oct. 21 /PRNewswire/ -- Potash Corporation of Saskatchewan Inc. ("PotashCorp") today noted the comments made by Premier Wall of Saskatchewan and thanked the Province for its thorough and thoughtful review of this matter.

PotashCorp shares the Province's bright outlook for our company and the industry. While the global economic recession had short-term impacts on our business, it did not derail the trends of population growth and improving diets that drive increased demand for potash. The combination of strong food demand and crop production issues has had a predictable impact on agricultural commodity prices, with most key global crops well above their 10-year average. This provides a highly supportive environment for farmers, and encourages them to maximize production through proper fertilization and other best farming practices. Strong demand and an improving pricing environment play to the strengths of PotashCorp, and we believe we are positioned to exceed the expectations of our worldwide customers and deliver compelling value to our stakeholders.

The PotashCorp Board of Directors recommends that shareholders reject BHP Billiton's unsolicited offer and not tender their shares into the offer. The PotashCorp Board believes that the offer is wholly inadequate and is not in the best interests of the company, its shareholders or other stakeholders.

Today, PotashCorp stands as a distinctly Saskatchewan and proudly Canadian company, and we are pleased to stand on our track record of performance, credibility and integrity. PotashCorp's corporate headquarters have been in Saskatoon for more than 35 years, including the past 21 years as a publicly traded company. More than 2,400 employees are based in Saskatchewan and New Brunswick, including key executive and corporate functions such as potash operations, finance, human resources, investor and corporate relations, legal and information technology. The few executives in charge of corporate support services who do not already live in Saskatoon are relocating. In addition, nine of PotashCorp's 12 directors are Canadian citizens. We are ambassadors of Saskatchewan and Canada, and champions of the potash resource, selling Saskatchewan potash to offshore markets through Canpotex, which employs 88 people, including 65 in their Saskatoon office. We have longstanding relationships with employees, suppliers and community organizations which are woven into the fabric of our company. We proudly carry the flags of Saskatchewan and Canada, building a global leader in the fertilizer industry from deep and enduring Saskatchewan roots.

Our corporate name says it all. We are the Potash Corporation of Saskatchewan.
