WESTLAKE CHEMICAL CORPORATION

NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

NOTE 1. Basis of Presentation

On November 30, 2006, Westlake Chemical Corporation (the “Company”) acquired the polyethylene and Epolene^® polymer businesses of Eastman Chemical Company (“Eastman”) headquartered in Longview, Texas, related assets and a 200-mile ethylene pipeline from Mt. Belvieu, Texas to Longview, Texas (“Longview Businesses”) for cash. Working capital assets other than inventory were not included in the acquisition.

The accompanying unaudited pro forma combined financial statements present the pro forma consolidated financial position and results of operations of the combined company based upon the historical consolidated financial statements of the Company and the historical combined financial statements of the Longview Businesses after giving effect to the adjustments described below.

The unaudited pro forma combined financial statements are prepared using the purchase method of accounting, with the Company treated as the acquirer. The unaudited combined financial statements reflect, on a pro forma basis, the combined statements of operations for the nine month period ended September 30, 2006 and for the year ended December 31, 2005 presented as if the acquisition of the Longview Businesses had been consummated as of January 1, 2005, the beginning of the Company’s 2005 fiscal year, and the combined balance sheet as of September 30, 2006 presented as if the acquisition had been consummated on September 30, 2006. These unaudited pro forma financial statements should be read in conjunction with (a) the December 31, 2005 financial statements of the Company included in the annual report on Form 10-K for the fiscal year ended December 31, 2005 and the September 30, 2006 financial information of the Company included in the quarterly report on Form 10-Q for the quarterly period ended September 30, 2006, and (b) the historical combined financial statements of the Longview Businesses included elsewhere in this Form 8-K.

Under the purchase method of accounting, the assets and liabilities of the Longview Businesses were recorded at their respective fair values as of the date of the acquisition, November 30, 2006. The Company has obtained preliminary third-party valuations of property, plant and equipment, intangible assets and certain other assets. The values of certain assets and liabilities are based on preliminary valuations, as allowed by U.S. generally accepted accounting principles, and are subject to adjustment as additional information is obtained. The Company cannot provide any assurance that such adjustments will not result in a material change.

Inventory at September 30, 2006 is recorded at the lower of cost or market. The unaudited pro forma combined financial statements have been adjusted to reflect changes in market prices subsequent to that date. As a result, the unaudited pro forma combined financial statements include an adjustment, Note 2, footnote (A3), to reduce the Longview Businesses September 30, 2006 inventory to the market value of the inventory at the date of the acquisition, November 30, 2006.

The unaudited pro forma combined financial statements are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of the Company would have been had the Longview Businesses acquisition occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position.

The accompanying unaudited pro forma combined financial statements do not give effect to any incremental costs resulting from feedstock supply agreements with Eastman or other external parties entered into as a result of the acquisition, realization of cost savings from operating efficiencies or other restructuring costs that may result from the acquisition of the Longview Businesses.
