</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On September&nbsp;6, 2007, Cameco filed a notice of intention to make a normal course issuer bid with
the Toronto Stock Exchange (TSX)&nbsp;to repurchase, over a one year period, for cancellation up to 5%
of the company&#146;s common shares, representing an investment of about $750&nbsp;million (Canadian) at
Cameco&#146;s share price on September&nbsp;6, 2007. The TSX accepted the company&#146;s notice on September&nbsp;7,
2007.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On September&nbsp;6, 2007, Cameco announced its intension to proceed with a significant program to<BR>
repurchase up to 5% of the company&#146;s common shares, representing an investment of about $750<BR>
million (Canadian) at Cameco&#146;s share price on September&nbsp;6, 2007. The company has concluded that,<BR>
in the near term, as attractive assets have not been available at reasonable valuations, the best<BR>
investment is repurchasing the company&#146;s shares.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On September&nbsp;6, 2007, Cameco filed a notice of intention to make a normal course issuer bid with<BR>
the TSX. Under the bid, which was accepted by the TSX on September&nbsp;7, 2007, Cameco will have the<BR>
ability, and has indicated its intention, to purchase for cancellation up to approximately 17.7<BR>
million of its common shares, representing 5% of the approximately 353.9&nbsp;million issued and<BR>
outstanding common shares as of September&nbsp;5, 2007.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Under the bid, Cameco may commence purchasing shares on September&nbsp;11, 2007 and may continue to do<BR>
so until September&nbsp;10, 2008, unless the company purchases the maximum allowable number of common<BR>
shares sooner or terminates the program. Cameco will make only market purchases of its common<BR>
shares and will pay the market price of the shares at the time of purchase.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cameco expects to use predominately cash on hand and cash from operations to fund the share<BR>
repurchase program.
