PPG Industries, Inc. David B. Navikas, Senior Vice President Finance and Chief Finance Officer Citi - 2012 Basic Materials Symposium Information current as of November 27, 2012

Forward-Looking Statements 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 within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, 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 Exchange Act, and the rules and regulations promulgated thereunder. Accordingly, many factors could cause actual results to differ materially from the forward-looking statements contained herein. Such factors include global economic conditions, 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, the realization of anticipated cost savings from restructuring initiatives, difficulties in integrating acquired businesses and achieving expected synergies therefrom, economic and political conditions in international markets, the ability to penetrate existing, developing and emerging foreign and domestic markets, foreign exchange rates and fluctuations in such rates, fluctuations in tax rates, the impact of future legislation, the impact of environmental regulations, unexpected business disruptions, 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. This presentation also contains statements about PPG’s agreement to separate its commodity chemicals business and merge it with Georgia Gulf Corporation or a subsidiary of Georgia Gulf (the “Transaction”). Many factors could cause actual results to differ materially from the company’s forward-looking statements with respect to the Transaction, including, the parties’ ability to satisfy the conditions to the closing of the Transaction; the parties’ ability to complete the Transaction on anticipated terms and schedule, including the ability of Georgia Gulf to obtain shareholder approval and the ability of the parties to obtain regulatory approvals and the anticipated tax treatment of the Transaction and related transactions; risks relating to any unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses and future prospects; business and management strategies for the management, expansion and growth of Georgia Gulf’s operations; Georgia Gulf’s ability to integrate PPG’s commodity chemicals business successfully after the closing of the Transaction and to achieve anticipated synergies; and the risk that disruptions from the Transaction will harm PPG’s or Georgia Gulf’s business. However, it is not possible to predict or identify all such factors. Consequently, while the list of factors presented here and in PPG’s Form 10-K for the year ended December 31, 2011 are 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, results of operations or liquidity. All information in this presentation speaks only as of November 27, 2012, and any distribution of this presentation after that date is not intended and will not be construed as updating or confirming such information. PPG undertakes no obligation to update any forward-looking statement, except as otherwise required by applicable law. 2

Spin-off Transaction Split-off Transaction Process: Shares in Spinco are distributed pro-rata to all PPG shareholders, which shares would then be converted into Georgia Gulf shares in the merger. • Each PPG shareholder would ultimately receive approximately .23 shares in Georgia Gulf (~35.2 Georgia Gulf shares / ~153.0 PPG shares) Shareholder Perspective: • Tax efficient distribution to shareholders of approximately $1.5B (a) a) Based on November 19, 2012 stock prices of PPG Industries, Inc. (NYSE:PPG) and Georgia Gulf Corporation (NYSE:GGC) Process: Offer is made to PPG shareholders to tender some or all of their PPG shares for Spinco shares, which shares would then be converted into Georgia Gulf shares in the merger. • Based on a ratio that is priced at a discount to Georgia Gulf stock market price – (c) Shareholder Perspective: • Tax efficient distribution to shareholders who have the portfolio capability and interest in owning Georgia Gulf (b) • Reduction in PPG share count (estimated at 6%-9%) so remaining PPG shareholders own a larger portion of PPG (a) & (b) b) If all Spinco shares are not distributed via a split, then a “clean-up” spin transaction will occur distributing the remaining Spinco shares evenly over the remaining PPG shareholders c) Specifics on exchange and discount have not yet been determined Distribution Alternatives 6

Commodity Chemical Transaction Status Completed: • Competition clearance – U.S. and Canada Underway/Pending: • SEC filings • Tax rulings • Georgia Gulf shareholder vote • Split-off exchange/tender offer Transaction remains on track for completion by early 2013 7
