METHANEX ANNOUNCES AGREEMENT WITH GEOPARK TO SECURE NATURAL GAS FOR CHILE OPERATIONS

Methanex Corporation announced today that it has signed a natural gas prepayment agreement with GeoPark Holdings Limited. Methanex will provide US$40 million in financing to support and accelerate GeoPark’s natural gas exploration and development activities in the Fell Block in Southern Chile. Under the arrangement, GeoPark will also provide Methanex with natural gas supply sourced from the Fell Block under a ten year supply agreement. GeoPark has been increasing its gas supply to Methanex since 2006 and its goal is to provide up to 10% of Methanex’s total natural gas needs in Chile by the end of 2008.

Methanex’s Latin America Senior Vice President, Paul Schiodtz, commented, “This prepayment agreement represents an important step to restore secure, long term gas supply to our plants in Chile. We are delighted to be working closely with GeoPark who have been very successful both discovering new gas and investing in infrastructure to increase natural gas deliveries to our plants.”

Mr. Schiodtz continued, “We are also very pleased with the results in the bidding process for oil and gas exploration in the south of Chile. The Chilean Government recently announced the participation of five other international oil and gas companies in gas exploration and development in areas which are all very close to our plants.”

James Park, CEO of GeoPark added, “This strategic alignment of Methanex and GeoPark strengthens both companies — by increasing the supply of natural gas in Chile for Methanex and by underpinning the long term development of GeoPark’s natural gas reserves. The agreement secures an economic long term market for all of GeoPark’s Chilean gas production while also providing a source of financing to accelerate capital investment.”

The risks and uncertainties include those attendant with producing and marketing methanol and successfully carrying out major capital expenditure projects in various jurisdictions, the ability to successfully carry out corporate initiatives and strategies, conditions in the methanol and other industries including the supply and demand balance for methanol, the success of natural gas exploration and development activities in southern Chile and our ability to obtain any additional gas in that region on commercially acceptable terms, actions of competitors and suppliers, changes in laws or regulations in foreign jurisdictions, world-wide economic conditions and other risks described in our 2006 Management’s Discussion & Analysis. Undue reliance should not be placed on forward-looking statements. They are not a substitute for the exercise of one’s own due diligence and judgment.
