Item 4.

Purpose of Transaction

Item 4 of the Statement is hereby amended and supplemented by adding the following paragraph immediately prior to the second to last paragraph thereof:

“Pursuant to section 300 of the Business Corporations Act (British Columbia), AEAC acquired on July 9, 2007 all of the outstanding Common Shares not already owned by the Reporting Persons.  Pursuant to the terms of the compulsory acquisition, each holder of the Common Shares that did not tender their Common Shares pursuant to the Offer was entitled to receive, in respect of each Common Share, 0.185 of a common share of Agnico.  Agnico now beneficially owns 100% of the Common Shares.

The Reporting Persons expect that the Common Shares will be delisted from the Toronto Stock Exchange at the close of business (Toronto time) on July 10, 2007.  The trading of Common Shares on the American Stock Exchange was suspended prior to the commencement of trading on July 10, 2007.  The Reporting Persons intend to cause the Issuer to make an application to cease to be a reporting issuer in Canada as soon as reasonably practicable, and the Reporting Persons also intend to cause the Issuer to delist the Common Shares from the American Stock Exchange and to cause the Issuer to deregister under Section 12(b) of the Exchange Act and to terminate the Issuer’s registration under Section 12(g) of the Exchange Act.”
