the applicable United States and Canadian legislation concerning

forward-looking information pertaining to:</font> the likelihood of

<font style="font-family: Arial; font-size: 11px">Forward looking
statements are based on the opinions and estimates of management as
of the date such statements are made, and they are subject to known
and unknown risks, uncertainties and other factors that may cause
the actual results, level of activity, performance or achievements
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 or the Private Placement on the terms
herein described or at all or pursue its evaluation and
environmental assessment activities or other intended purposes of
the proceeds of the offering, which could have significant impacts
on Denison. In addition, the currently anticipated evaluation and
environmental assessment activities may not be maintained after
further testing or Denison may decide or otherwise be required to
alter or discontinue testing, evaluation and development work, if
it is unable to maintain or otherwise secure the necessary
approvals or resources (such as testing facilities, capital
funding, etc.) and the Company may not be able to, or may choose
not to, proceed to a FS for Phoenix. Denison believes that the
expectations reflected in this forward-looking information are
reasonable and 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 &#x201C;Risk Factors&#x201D;. These
factors are not, and should not be construed as being
exhaustive</font></div>

this report contains forward-looking information pertaining to: the

<font style="font-family: Arial; font-size: 11px">Forward looking
statements are based on the opinions and estimates of management as
of the date such statements are made, and they are subject to known
and unknown risks, uncertainties and other factors that may cause
the actual results, level of activity, performance or achievements
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 or the Private Placement on the terms
herein described or at all or pursue its evaluation and
environmental assessment activities or other intended purposes of
the proceeds of the offering, which could have significant impacts
on Denison. In addition, the currently anticipated evaluation and
environmental assessment activities may not be maintained after
further testing or Denison may decide or otherwise be required to
alter or discontinue testing, evaluation and development work, if
it is unable to maintain or otherwise secure the necessary
approvals or resources (such as testing facilities, capital
funding, etc.) and the Company may not be able to, or may choose
not to, proceed to a FS for Phoenix. Denison believes that the
expectations reflected in this forward-looking information are
reasonable and 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 &#x201C;Risk Factors&#x201D;. These
factors are not, and should not be construed as being
exhaustive.</font></div>
