BHP Billiton amended and varied the terms of its all-cash offer to acquire all of the issued and outstanding common shares of Potash Corporation of Saskatchewan Inc. together with any associated rights issued and outstanding under the PotashCorp Shareholder Rights Plan, at a price of US$130 in cash per PotashCorp common share.

On Sept. 20, 2010, the Canadian Competition Bureau issued a Supplementary Information Request in respect of the offer as is permitted by the Competition Act (Canada).

Under the Competition Act, the offer cannot be completed until 30 days after BHP Billiton complies with the Supplementary Information Request unless the Commissioner of Competition issues an advance ruling certificate or "no-action" letter before that time, provided that there is no order issued by the Competition Tribunal in effect prohibiting completion at the relevant time. BHP Billiton intends to comply expeditiously with the Supplementary Information Request.
