        <footnote id="F1">Upon the vesting of restricted stock units on February 18, 2012, which were granted to the reporting person on February 18, 2009, the reporting person deferred the receipt of 2,934 shares of common stock and received instead 2,934 shares of phantom stock pursuant to the PPG Industries, Inc. Deferred Compensation Plan for Directors.  As a result, the reporting person is reporting the conversion of restricted stock units relating to 2,934 shares of common stock in exchange for an equal number of shares in phantom stock.</footnote>
