required to be taken for the eventual combination of the two companies, including the possibility that
approvals or clearances required to be obtained from regulatory and other agencies and bodies will not be
obtained in a timely manner, disruption from the proposed transaction making it more difficult to maintain

Forward-Looking Statements
These
forward-looking
statements
are
based
on
certain
assumptions
and
analyses
made
by us in light of our experience and perception of historical trends, current conditions and
expected
future
developments
as
well
as
other
factors
we
believe
are
appropriate
in
the
circumstances. Expected future developments are based, in part, upon assumptions
respecting our ability to successfully integrate the businesses of Agrium and CF, or any
other recent acquisitions.
All of the forward-looking statements contained herein are qualified by these cautionary
statements
and
by
the
assumptions
that
are
stated
or
inherent
in
such
forward-looking
statements. Although we believe these assumptions are reasonable, undue reliance
should not be placed on these assumptions and such forward-looking statements. The
key assumptions that have been made in connection with the forward-looking statements
include, but are not limited to, CF’s acceptance of Agrium’s proposal and the entering
into of a definitive agreement to effect the proposed transaction, the market value of
Agrium common shares issued in connection with the proposed acquisition, our ability to
successfully integrate within expected time frames and costs, and realize the expected
combination benefits and synergies and costs savings from the combination of the
businesses of Agrium and CF, or any other recent business acquisitions, and our ability
to maintain relationships with customers, employees and suppliers during the course of
the proposed transaction.

Compelling Value for Shareholders of Both Companies
For Agrium Shareholders:
Accretive to Agrium shareholders
Creates a global leader in crop nutrients
Continues Agrium’s growth across value chain
Proven track record of successful acquisitions and

businesses


26
growing across the value chain
Agrium is Well Positioned for the Future
Diversified by Geography, Business and
Product line (crop nutrients, seed, crop
protection), positioned to capitalize on the
strong long-term industry fundamentals
We expect crop nutrient demand to show
improvement in 2009, as growers make up for
reduction in application in the fall of 2008 and
early 2009
Agrium has an excellent mix of assets, a strong
balance sheet and a proven track record of
delivering value to shareholders
