PITTSBURGH – PPG Industries has begun its exchange offer related to the split-off transaction of its commodity chemicals business. The split-off transaction is in connection with the separation and merger of Eagle Spinco Inc., a wholly owned subsidiary of PPG that will own substantially all of the assets and liabilities of PPG’s commodity chemicals business, with a subsidiary of Georgia Gulf Corp. As previously announced, PPG entered into definitive agreements as of July 18, 2012, to separate and merge its commodity chemicals business with Georgia Gulf.

As part of the exchange offer, PPG shareholders have the option to exchange all, some or none of their shares of PPG common stock for shares of Eagle Spinco common stock, subject to proration. Shares of Eagle Spinco common stock will convert automatically into the right to receive shares of Georgia Gulf common stock at the closing of the merger of a Georgia Gulf subsidiary with and into Eagle Spinco, which is expected to occur promptly after completion of the exchange offer.

Tendering PPG shareholders are expected to receive approximately $1.11 of Georgia Gulf common stock for every $1.00 of PPG common stock tendered, subject to an upper limit.

PPG will determine the prices at which shares of PPG common stock and shares of Eagle Spinco common stock (and ultimately Georgia Gulf common stock) will be exchanged by reference to the simple arithmetic average of the daily volume-weighted average prices of PPG common stock and Georgia Gulf common stock, respectively, on the New York Stock Exchange on each of the last three trading days of the exchange offer.

PPG currently expects to issue approximately 35,236,010 shares of Eagle Spinco common stock in the exchange offer.

The exchange offer is designed to permit PPG shareholders to exchange their shares of PPG common stock for shares of Eagle Spinco common stock at a discount of 10 percent to the per-share value of Georgia Gulf common stock, subject to a limit of 3.9745 shares of Eagle Spinco common stock per share of PPG common stock. Each share of Eagle Spinco common stock will then convert automatically into the right to receive one share of Georgia Gulf common stock following the merger of the Georgia Gulf subsidiary with and into Eagle Spinco. The shares of Georgia Gulf common stock issued in the merger are expected to represent approximately 50.5 percent of the Georgia Gulf common stock that will be outstanding after the merger.
