CALGARY, Alberta -- Agrium Inc. (TSX and NYSE: AGU) today announced that it has entered into an agreement to issue 21,551,700 common shares at a price of $58.00 per share representing gross proceeds of approximately $1.25-billion through a syndicate of underwriters, with RBC Capital Markets acting as lead manager and bookrunner, Merrill Lynch & Co., Scotia Capital Inc. and UBS Securities Canada Inc. acting as co-lead managers, and including BMO Nesbitt Burns Inc., Credit Suisse Securities (Canada), Inc., National Bank Financial Inc., CIBC World Markets Inc. and TD Securities Inc.  Agrium has granted the underwriters an option exercisable in whole or in part for a period of 30 days after closing of the offering to purchase up to an additional 2,155,100 common shares at a price of $58.00 per share to cover over-allotments, if any.  Should the underwriters' over-allotment option be fully exercised, the total gross proceeds of the offering will be approximately $1.375-billion.  The Company expects the offering to close on or about December 18, 2007, subject to the satisfaction or waiver of all of the conditions set forth in the underwriting agreement.

A preliminary prospectus supplement dated December 10, 2007, under the Company's short form base shelf prospectus dated August 22, 2007 and under the Company's related effective Registration Statement on Form F-10 in respect of the offering of the common shares was filed on December 10, 2007 with the Canadian securities regulatory authorities in each of the provinces of Canada and with the United States Securities and Exchange Commission under the multi-jurisdictional disclosure system.  A final prospectus supplement in respect of the offering of the common shares will be filed with the same regulatory authorities in Canada and the United States.  On December 3, 2007, the Company filed an amendment to its short form base shelf prospectus to increase the maximum amount of securities that may be offered thereunder from $1-billion to $3-billion.

The Company intends to use the net proceeds from the offering to fund  a portion of the purchase price of its previously announced cash tender offer for all of the outstanding shares of common stock of UAP Holding Corp., which was commenced on December 10, 2007.  The Company estimates that the aggregate cash consideration for the acquisition of UAP will be approximately $2.15-billion, plus indebtedness of UAP to be assumed or refinanced.  The Company also plans to borrow under available credit facilities to pay the balance of the purchase price for UAP and to refinance certain indebtedness of UAP and its subsidiaries.  The Company expects the acquisition of UAP to be completed in early 2008.
