May&nbsp;16, 2005 and the date upon which the Company has acquired the maximum
number of common shares permitted under the purchase program or otherwise

    <TD align="left" valign="top">Methanex believes that purchasing its shares under the normal course
issuer bid is in the best interests of its shareholders and represents an
effective use of the Company&#146;s financial resources. The planned share
repurchase is consistent with Methanex&#146;s balanced approach to the
utilization of cash and reflects the Company&#146;s ongoing commitment to
returning excess cash to shareholders. At the closing price of
Methanex&#146;s common shares on the TSX on May&nbsp;13, 2004, the planned share
repurchase represents a financial commitment of approximately US$70
million. Methanex currently has over US$150&nbsp;million in cash, an undrawn
US$250&nbsp;million credit facility</TD>
