The line item reporting that 9,845 shares of common stock were sold at $67.0765 per share was actually a summary of certain other lines and was not, itself, a transaction. Therefore, the number of shares of common stock held by the reporting person was incorrectly reported with respect to each subsequent transaction shown on such Form 4, and was also incorrectly reported on the subsequent Forms 4 filed by the reporting person on December 11, 2012 and March 4, 2013. In addition, the line item reporting that 500 shares of common stock were sold at $500 per share was incorrect. The $500 should have been $67.23. In accordance with the Securities and Exchange Commission's No Action Letter dated June 25, 2008, we have aggregated the sales that occurred on August 6, 2012 for ease of reporting. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions ranging from $67.01 to $67.255, inclusive. The reporting person undertakes to provide to Westlake Chemical Corp., any security holder of Westlake Chemical Corp. or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote (2) to this Form 4. The transactions were shown individually on the reporting person's original Form 4 filed August 8, 2012. David R. Hansen by Richard C. Kroger PoA 2013-03-18
