Westlake Chemical Corporation (NYSE: WLK) announced today that it has raised $154 million of tax-exempt revenue bonds due November 1, 2035 with an interest rate of 6.50% per year (the "Bonds"). The Bonds were issued through the Louisiana Local Government Environmental Facilities and Community Development Authority under the Gulf Opportunity Zone ("GO Zone") Act of 2005 and the Emergency Economic Stabilization Act of 2008 (the latter known as the "Ike Zone Act").

The proceeds from the Bonds were loaned by the Authority to Westlake which in turn issued Senior Notes to the Authority to evidence and secure its payment obligations to the Authority. The Senior Notes are unsecured and will rank equally in right of payment with other existing and future unsecured senior indebtedness of Westlake. The proceeds will be used to expand, refurbish and maintain the company's facilities in the Louisiana Parishes of Calcasieu and Ascension, including the construction of the company's new chlor-alkali project at Geismar, Ascension Parish.
