SASKATOON, Oct. 5 /PRNewswire-FirstCall/ - While Potash Corporation of Saskatchewan Inc. (PotashCorp) continues to review the report prepared by The Conference Board of Canada, which details the impact that an acquisition of PotashCorp by BHP Billiton (BHP) would have on Canada and the province of Saskatchewan in particular, the company made the following observations:

The Saskatchewan government notes in its press release that BHP's proposed takeover of PotashCorp would reduce provincial revenues while having little or no net effect on employment in the industry. We would further note that the revenue loss is both:

    i)  understated, as the report chose to assume that BHP would not operate
        full out in direct contradiction of previous BHP public statements;
        and
    ii) unique to the BHP bid because of its involvement in the Jansen Lake
        greenfield project

The Board of Directors of PotashCorp would encourage the Government of Saskatchewan to continue to remain open to reviewing alternative bids on a fact-based approach, rather than the speculative approach taken by The Conference Board of Canada's report.

PotashCorp has told the Conference Board of Canada that the position it has taken is that all potential interested parties should commit to the following as a starting point, so that prospective Provincial resource revenues were not negatively impacted:

    -  support the sale of offshore potash through Canpotex
    -  purchase potash on an arms-length basis, for their own needs as a
       consumer
    -  support the continued profit maximization strategies employed by
       PotashCorp's existing management, as well as the company's ongoing
       capital expenditures for future potash expansions

The company believes and told the Conference Board that such assurances would be integral to any alternative expressions of interest. The Conference Board chose to ignore PotashCorp's position in its report.

The company reminds its shareholders that its Board of Directors unanimously recommends that PotashCorp shareholders reject the BHP offer and not tender their shares. The offer is wholly inadequate and is not in the best interests of the company, its shareholders or other stakeholders.

PotashCorp looks forward to Investment Canada's review, which was extended yesterday, which will assess whether an acquisition of PotashCorp by BHP would comply with applicable Canadian law and federal government policies, including the requirements of the Investment Canada Act.
