On January 10, 2013, the stockholders of Georgia Gulf Corporation (the “Company” or “Georgia Gulf”) approved the First Amendment to the Georgia Gulf 2011 Equity and Performance Incentive Plan (the “Plan”) to (i) increase the authorized number of shares of Georgia Gulf common stock reserved for issuance under the Plan by 1,800,000 shares  to a total of 3,600,000 shares (including those shares as to which grants previously have been made); (ii) permit the grant under the Plan of awards in substitution for or conversion of stock or stock-based awards held by awardees of an entity engaging in a corporate acquisition or merger transaction with Georgia Gulf or any of its subsidiaries, with the shares of Georgia Gulf common stock delivered under the substituted or converted award not counting against the share limit or other limits on the number of shares of Georgia Gulf common stock available for issuance under the Plan; and (iii) limit the aggregate amount of stock or stock-based awards which a non-employee director may be granted under the Plan during any calendar year to a value as of their respective dates of grant of $300,000 (collectively, the “Plan Amendment”). Georgia Gulf’s board of directors unanimously approved the Plan Amendment on November 26, 2012, subject to approval by Georgia Gulf’s stockholders at the special meeting. The effectiveness of the First Amendment to the Plan is contingent on the consummation of the Merger.

The foregoing description of the Plan Amendment does not purport to be complete and is qualified in its entirety by reference to the description of the material terms of the Plan, as amended, set forth in the Company’s Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on December 6, 2012, under the heading “Proposal 3—Proposal to Approve the First Amendment to the Georgia Gulf Corporation 2011 Equity and Performance Incentive Plan,” which description is incorporated by reference herein.
