    <TD>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;5, 2005, the planned share repurchase represents a financial commitment of
approximately US $132&nbsp;million. Methanex currently has over US $150&nbsp;million in cash, an
undrawn US $250&nbsp;million credit facility and continued strong cash generation capability.
Methanex intends to finance the purchase of common shares under the bid with cash on hand.</TD>
