of Denison to be materially different from those expressed or
implied by such forward-looking statements. For example, if market
conditions remain volatile and/or COVID-19 mitigation measures
result in more social and economic disruptions, Denison may not be
able to complete the Offering on the terms herein described or at
all, which could have significant impacts on Denison and its
ability to continue as a going concern. Denison believes that the
expectations reflected in this forward-looking information are
reasonable but no assurance can be given that these expectations
will prove to be accurate and results may differ materially from
those anticipated in this forward-looking information. For a
discussion in respect of risks and other factors that could
influence forward-looking events, please refer to the factors
discussed in Denison&#x2019;s Annual Information Form dated March
13, 2020 under the heading &#x2018;Risk Factors&#x2019;. These
factors are not, and should not, be construed as being
exhaustive.</font></div>
