Agrium Inc., Canada's giant fertilizer manufacturer, which is currently, involved in an aggressive battle to takeover its chief American rival CF Industries, on Wednesday shared plans of nominating a slate of directors, who would stand for upcoming election at the American company's 2010 Annual StockHolder Meeting.

A letter was sent regarding the same to CF's Board of Directors, in which Agrium Chief Executive Michael Wilson stressed that CF's efforts to hinder the company's proposed $5 Billion acquisition bid were completely "unreasonable".

"The time is overdue for you to remove these preclusive barriers and let your stockholders decide for themselves whether to accept Agrium's offer. The company is open to discussing how to best proceed with this transaction, including possible modifications to the structure of our offer", the letter read.

As per Agrium's offers, the company would, in its "best and final" bid, pay CF holders $45 cash and one common Agrium share for each CF share they hold. The deal values CF shares at $101.97.

In pre-market, both Agrium and CF recorded no activity.
