Private Securities Litigation Reform Act of 1995 and similar Canadian legislation concerning the
business, operations and financial performance and condition of Denison.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Forward looking statements include, but are not limited to, statements with respect to estimated
production; the development potential of Denison&#146;s properties, including those of its joint
ventures; the future price of uranium; the estimation of mineral reserves and resources; the
realization of mineral reserve estimates; the timing and amount of estimated future production;
costs of production; capital expenditures; success of exploration activities; permitting time lines
and permitting, mining or processing issues; currency exchange rate fluctuations; government
regulation of mining operations; environmental risks; unanticipated reclamation expenses; title
disputes or claims; and limitations on insurance coverage. Generally, these forward-looking
statements can be identified by the use of forward-looking terminology such as &#147;plans&#148;, &#147;expects&#148;
or &#147;does not expect&#148;, &#147;is expected&#148;, &#147;budget&#148;, &#147;scheduled&#148;, &#147;estimates&#148;, forecasts&#148;, &#147;intends&#148;,

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">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, including but not limited to risks related to: unexpected events during construction,
expansion and start-up; variations in ore grade, tonnes mined, crushed or milled; delay or failure
to receive board or government approvals; timing and availability of external financing on
acceptable terms; actual results of current exploration activities; conclusions of economic
evaluations; changes in project parameters as plans continue to be refined; future prices of
uranium and vanadium; possible variations in ore reserves,
grade or recovery rates; failure of plant, equipment or processes to operate as anticipated;
accidents, labour disputes and other risks of the mining industry; delays in the completion of
development or construction activities, as well as those factors discussed in or referred to under
the heading &#147;Risk Factors&#148; in Denison&#146;s Management&#146;s Discussion and Analysis dated March&nbsp;18, 2009
available at <U>http://www.sedar.com</U> and at <U>http://www.sec.gov</U>. Although management of Denison has
attempted to identify important factors that could cause actual results to differ materially from
those contained in forward-looking statements, there may be other factors that cause results not to
be as anticipated, estimated or intended.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">There can be no assurance that such statements will prove to be accurate, as actual results and
future events could differ materially from those anticipated in such statements. Accordingly,
readers should not place undue reliance on forward-looking statements. Denison does not undertake
to update any forward-looking statements that are incorporated by reference herein, except in
accordance with applicable securities laws. Mineral resources, which are not mineral reserves, do
not have demonstrated economic viability. Readers should refer to the Annual Information Form and
the Form 40-F of Denison for the year ended December&nbsp;31, 2007 and other continuous disclosure
documents filed since December&nbsp;31, 2007 available at <U>http://www.sedar.com</U>, for further information
relating to their mineral resources and mineral reserves.

United States investors are advised that while such terms are recognized and required by Canadian

Inferred Mineral Resources may not form the basis of feasibility or other economic studies. <B>United
States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral
Resources will ever be converted into Mineral Reserves. United States investors are also cautioned
not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or
legally mineable.</B>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Northern holds a 60% interest (Hathor Exploration Limited 40%) in the Russell Lake uranium property
located immediately adjacent to Denison&#146;s major new Wheeler River uranium discovery in the
Athabasca Basin of northern Saskatchewan. Through this transaction, Denison will consolidate, as
one contiguous package, its land position between Wheeler River and another important Denison
discovery in the Basin, Moore Lake. The Russell Lake property exhibits a number of strong
targets.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Pursuant to the proposed plan of arrangement, Denison would acquire Northern on the basis of 0.0920
Denison common shares for each share of Northern (the &#147;Exchange Ratio&#148;). In addition, all
outstanding options and warrants of Northern will be exchanged for replacement options and warrants
of Denison, the number and exercise price of which will be determined using the Exchange Ratio.
The transaction values the Northern shares at $0.206, based on the closing price of the shares of
Denison on April&nbsp;30, 2009 representing a 64.8% premium to the April&nbsp;30, 2009 closing price of
Northern.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">The transaction is subject to completion of due diligence by both parties, the execution of
definitive agreements and the obtaining of regulatory and Northern Continental shareholder
approval. Upon completion of the proposed transaction, it is estimated that Denison will have
approximately 231&nbsp;million shares outstanding (not including the exercise of any outstanding
warrants and options). Former shareholders of Northern will hold approximately 2.2% of the
outstanding shares of Denison. The transaction is expected to close in July&nbsp;2009.

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

intended.

readers should not place undue reliance on forward-looking statements. Denison does not undertake
to update any forward-looking statements that are incorporated by reference herein, except in
accordance with applicable securities laws. Mineral resources, which are not mineral reserves, do
not have demonstrated economic viability. Readers should refer to the Annual Information Form and
