METHANEX ANNOUNCES INCREASE TO QUARTERLY DIVIDEND FOR THE SIXTH CONSECUTIVE YEAR AND A NEW 10% SHARE REPURCHASE PROGRAM

Methanex Corporation announced today that its Board of Directors has approved an 11 percent increase in its quarterly dividend to shareholders, from US$0.14 per share to US$0.155 per share. The increased dividend will apply commencing with the dividend payable on June 30, 2008 to holders of common shares of record on June 16, 2008.

Bruce Aitken, President and CEO of Methanex commented, “This is the sixth year in a row that we have increased our dividend since its inception in 2002. The increase to our regular dividend reflects our continued confidence in the outlook for our business and the methanol industry.”

In addition, Methanex’s Board of Directors approved a new normal course issuer bid that will commence on the expiration of the Company’s existing normal course issuer bid. Under the new bid, the Company may repurchase up to 7,909,393 common shares of the Company, representing 10 percent of the public float of the issued and outstanding shares as at May 2, 2008. Under the existing bid, which expires on May 16, 2008, the Company has purchased 8,422,100 shares as of May 2, 2008 at an average price of CDN$26.46 (US$25.97). As of May 2, 2008, there were 94,646,917 Methanex common shares issued and outstanding.

Mr. Aitken added, “Our announcement of a new share repurchase program reflects our balanced approach to the utilization of cash and builds on our long track record of returning excess cash to shareholders. Since 2000, we have reduced our shares outstanding from about 170 million to under 95 million. With $465 million of cash on hand at the end of the first quarter of 2008, we have the financial strength and flexibility to meet our commitments for our Egypt project, pursue investment opportunities to accelerate the development of natural gas in southern Chile, invest in other strategic initiatives and continue to return excess cash to shareholders.”

The normal course issuer bid repurchase program will be carried out through the facilities of the TSX. Purchases under the program will commence on May 20, 2008 and terminate on the earlier of May 19, 2009 and the date upon which the Company has acquired the maximum number of common shares permitted under the purchase program or otherwise decided not to make further purchases. Purchases will be made from time to time at the then current market price of the Company’s common shares as traded on the TSX and the common shares purchased will be cancelled. Daily repurchases under the program will not exceed 102,841 shares per day (which is 25 percent of the Company’s average daily trading volume for the six month period ending April 30, 2008), subject to purchases made in accordance with the block purchase exception under the TSX rules. The Company has entered into an automatic securities purchase plan with its broker in connection with purchases to be made under this program.
