PITTSBURGH--May 20, 2005--PPG Industries, Inc. , today announced that it has commenced cash tender offers to purchase up to $100,000,000 in aggregate principal amount of its outstanding 6.500% notes due November 1, 2007 (the "2007 Notes"), up to $175,000,000 in aggregate principal amount of its outstanding 7.050% notes due August 15, 2009 (the "2009 Notes") and, to the extent that the aggregate principal amount of 2007 Notes and 2009 Notes validly tendered and not withdrawn is less than $275,000,000, an aggregate principal amount of its outstanding 6.875% notes due February 15, 2012 equal to the balance, if any, of $275,000,000 less the aggregate principal amount of 2007 Notes and 2009 Notes validly tendered and not withdrawn (the "2012 Notes," and together with the 2007 Notes and 2009 Notes, collectively, the "Notes").

"We believe this transaction is another step in our ongoing effort to maximize the financial flexibility for PPG," said William H. Hernandez, Senior Vice President, Finance.

We believe we will be able to refinance these maturities in the near future with lower cost alternatives if we so desire."

Forward-Looking Statement

Statements contained herein relating to matters that are not historical facts are forward-looking statements reflecting PPG's current view with respect to future events and financial performance. These matters involve risks and uncertainties that may affect PPG's operations, as discussed in PPG's filings with the Securities and Exchange Commission pursuant to Sections 13(a), 13(c) or 15(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. Accordingly, many factors may cause actual results to differ materially from the forward-looking statements contained herein.

Such factors include increasing price and product competition by foreign and domestic competitors, fluctuations in cost and availability of raw materials, the ability to maintain favorable supplier relationships and arrangements, economic and political conditions in international markets, the ability to penetrate existing, developing and emerging foreign and domestic markets, which also depends on economic and political conditions, foreign exchange rates and fluctuations in such rates, and the unpredictability of existing and possible future litigation, including litigation that could result if the asbestos settlement discussed in PPG's filings with the Securities and Exchange Commission does not become effective. However, it is not possible to predict or identify all such factors. Consequently, while the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.

Consequences of material differences in results compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on PPG's consolidated financial condition, operations or liquidity.
