exploration project in Western Australia for $346.5&nbsp;million (US). Cameco funded the acquisition
through existing credit facilities.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;5 &#151; Full Description of Material Change</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On August&nbsp;11, 2008, Cameco completed the acquisition of a 70% interest in the Kintyre uranium
exploration project in Western Australia for $346.5&nbsp;million (US). On July&nbsp;9, 2008, Cameco issued a
press release announcing it had signed an agreement to acquire this interest and that closing of
the agreement was subject to ministerial approval in Western Australia and execution of certain
agreements with the Martu people who are the traditional owners of the land. That approval was
received and agreements executed by the Martu allowing closing of the acquisition to proceed on
August&nbsp;11, 2008.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">A joint venture comprised of Cameco (70%) and Mitsubishi Development Pty Ltd (30%) purchased the
Kintyre project from Rio Tinto for $495.0&nbsp;million (US)&nbsp;through a bidding process. Cameco will
operate the project and funded its share of the purchase price through existing credit facilities.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Kintyre is an advanced exploration project located in Western Australia about 1,250 kilometres
northeast of Perth. Uranium was first discovered in the area in 1985 and followed up with further
exploration that identified eight deposits. The project was placed in care and maintenance in 1988
when uranium prices declined below $12 per pound (US). Rio Tinto initiated the sale process in
2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Based upon Cameco&#146;s due diligence, it is estimated that the Kintyre project may host potential
mineral deposits ranging from 62 to 80&nbsp;million pounds U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8</SUB> in total, with an
average grade between 0.3% and 0.4% U<SUB style="font-size: 85%; vertical-align: text-bottom">3</SUB>O<SUB style="font-size: 85%; vertical-align: text-bottom">8</SUB>. These estimates are conceptual in
nature. The basis for these conceptual estimates includes 355 historical diamond drill holes
totalling 70,279 metres. There has been insufficient exploration, however, to define a resource at
the Kintyre project in compliance with Canadian mineral resource reporting standards. Although
Cameco plans to undertake an exploration program with the objective of estimating a resource for
the deposits, it is uncertain if further exploration will result in the target being delineated as
a mineral resource.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The joint venture plans to work toward a mine development agreement with the Martu.

<DIV style="font-family: 'Times New Roman',Times,serif">



<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Development of the Kintyre deposits is subject to state government approval. The current Labor
government in Western Australia permits uranium exploration, but continues to oppose new uranium
mine development. However, Australian governments and political parties generally are becoming more
supportive of uranium development. In 2007, the federal Australian Labor Party abandoned a long-<BR>
standing policy opposing development of new uranium mines. Since forming the national government,
the party has become supportive of uranium mining generally in Australia.
