Business Wire

PITTSBURGH -- December 21, 2012

PPG Industries (NYSE:PPG) today announced that it has receiveda favorable
private letter ruling from the U.S. Internal Revenue Service regarding the
previously announced separation of its commodity chemicals business and
subsequent merger of a newly formed company owning the commodity chemicals
business (“Splitco”) with a subsidiary of Georgia Gulf Corporation. The
receipt of the ruling is a closing condition of the transaction with Georgia
Gulf and an important milestone in the completion of the transaction. As a
result, PPG now intends to commence its exchange offer to split off its
commodity chemicals business in the near term with the closing of the exchange
offer and merger expected to occur in late January 2013. The terms of the
exchange offer will be released upon commencement of the offer.

On July 19, 2012, PPG announced that it would form a new company by separating
its commodity chemicals business through a spinoff or split-off, and then
immediately merging the business with Georgia Gulf or a Georgia Gulf
subsidiary in a Reverse Morris Trust transaction. Immediately following the
merger, Splitco shareholders will own approximately 50.5 percent of Georgia
Gulf, with existing Georgia Gulf shareholders owning approximately 49.5
percent of Georgia Gulf.
