NOTES:

The common stock equivalents consist of the shares reserved for issuance under 
PPG's stock option plan and deferred under PPG's deferred compensation and 
earnings growth plans.

The fully diluted earnings per share calculations are submitted in accordance 
with Regulation S-K item 601(b)(11) although not required by footnote 2 to 
paragraph 14 of APB Opinion No. 15 because they result in dilution of less 
than three percent.

All amounts are in millions except per share data.
