are not simply reiterations of historical facts. These statements are presented
to inform stakeholders of the views of Mitsui's management but should not be
relied on solely in making investment and other decisions. You should be aware
that a number of important risk factors could lead to outcomes that differ
materially from those presented in such forward-looking statements. These
include, but are not limited to, (i) change in economic conditions that may lead
to unforeseen developments in markets for products handled by Mitsui, (ii)
fluctuations in currency exchange rates that may cause unexpected deterioration
in the value of transactions, (iii) adverse political developments that may
create unavoidable delays or postponement of transactions and projects, (iv)
changes in laws, regulations, or policies in any of the countries where Mitsui
conducts its operations that may affect Mitsui's ability to fulfill its

course of its operations, Mitsui adopts measures to control these and other
types of risks, but this does not constitute a guarantee that such measures will
be effective.
