Agrium Increases and Extends Royster-Clark Offer.

CALGARY, Alberta -- Agrium Inc. (TSX:AGU)(NYSE:AGU) announced today that it has increased its offer to purchase all outstanding Royster-Clark Income Depositary Securities (IDSs) to $11.00 (Canadian) cash per IDS, and as a result, has extended the expiry time of its bid until midnight (Vancouver time) on January 23, 2006. The increased offer price represents an allocation of $2.20 per Common Share forming part of the IDS and $8.80 for each Subordinated Note forming part of the IDS. Agrium also has reduced its minimum tender condition to 66 2/3 percent, and has removed the due diligence condition.

Agrium and Royster-Clark had previously reached an agreement that Royster-Clark's rights plan would not apply to Agrium's bid, therefore providing the opportunity for Royster-Clark unitholders to take full advantage of Agrium's all cash offer.

Agrium will file and deliver a notice of extension and variation of its offer today.

"Royster-Clark's Board has declined Agrium's attempts to negotiate a friendly transaction," said Mike Wilson, Agrium President and CEO. "After more than two months, Royster-Clark has not presented an alternative for its investors."

"We believe that Agrium's enhanced offer is the best value available for unitholders. It fully reflects Royster-Clark's recent financial estimates, which are consistent with Agrium's expectations. It also fully reflects the modest recovery of value by comparable trusts since the Canadian government's tax policy announcement."
