UEX Corporation ("UEX") announced today that it did not receive shareholder approval for its previously announced Shareholder Rights Plan ("Rights Plan") at its Annual General Meeting ("AGM") held on June 26, 2007. As a result, the Rights Plan terminated following completion of the AGM.

Approximately 111 million shares (61% of UEX's 182.1 million issued and outstanding common shares) were represented at the AGM. As proxies representing approximately 52% of these shares (including the proxy representing the approximately 40 million shares held by Cameco Corporation) were against approval of the Rights Plan, UEX withdrew this item of business from the agenda for the AGM. UEX noted that over 95% of the shares represented at the AGM voted in favour of the re-election of UEX's board of directors.

"I am very disappointed that the Rights Plan was not approved, as management believes that the Rights Plan would be in the best interest of minority shareholders," said Stephen Sorensen, President and CEO of UEX.
