Hexion Posted Strong Year-over-Year Performance
(1) Segment EBITDA and Adjusted EBITDA are non-GAAP financial measures. The closest GAAP financial measure is Net Income (Loss). A table that reconciles these two measures is at the end of this
presentation. Management believes that Adjusted EBITDA is meaningful to investors because the Company is required to have an Adjusted EBITDA to Fixed Charges ratio of greater than 2.0 to 1.0 to incur
additional indebtedness under its indenture for the Second Priority Senior Secured Notes. As of December 31, 2007, the Company was able to satisfy this covenant and incur additional indebtedness under its
indentures. December 31, 2007 Adjusted EBITDA includes $55 million of in-process Hexion synergies and $38 million of acquisition adjustments.
(2) Transaction remains subject to various conditions, including expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Act, review by foreign jurisdictions and other customary closing
conditions.
