ALL AMOUNTS ARE STATED IN U.S.$

CALGARY, Alberta -- Agrium Inc. (TSX and NYSE: AGU) announced today that it extended its previously announced tender offer for all of the common stock of UAP Holding Corp. (NASDAQ: UAPH) until 12:00 midnight, New York City time, on Wednesday, April 30, 2008. The tender offer was previously set to expire today at midnight, New York City time.

Agrium extended the offer because all of the conditions to completion of the offer have not yet been satisfied. In particular, the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act (the HSR Act) has not yet expired or been terminated. As of 5:00 p.m., New York City time, on March 13, 2008, approximately 31.34 million shares of common stock of UAP had been tendered in and not withdrawn from the offer.

In addition, Agrium announced that it intends to voluntarily withdraw its notification and report form from the Federal Trade Commission (FTC) later today. As a result of informal discussions between Agrium and the staff (Staff) of the FTC since the original filing of its notification and report form, Agrium believes that Staff’s concerns are limited to approximately a dozen UAP stores (out of a total of approximately 370 stores). Agrium plans to work with Staff in an attempt to further reduce or eliminate the stores of concern.

Agrium plans to re-file its notification and report form when it believes that Staff’s remaining competitive concerns have been fully addressed or remedied.

Agrium remains highly confident of a successful close to the transaction. Agrium believes that the closing of the transaction will occur by early summer of 2008.
