The 2005 NQ Plan provides that effective October 1, 2014 and thereafter, any amount credited in a participant's account to the phantom stock fund (i.e. the theoretical Worthington Industries, Inc. common share deemed investment option) may not be transferred to an alternative deemed investment option under the 2005 NQ Plan until distribution from the 2005 NQ Plan. Distributions are made only in common shares of Worthington Industries, Inc. and generally commence upon leaving Worthington Industries, Inc. and its subsidiaries. The amount shown reflects additional unfunded theoretical Worthington Industries, Inc. common shares (i.e. phantom stock) credited pursuant to the dividend reinvestment feature of the 2005 NQ Plan. /s/Patrick J.
