(1)	1,875 shares vested on December 18, 2010 and, thereafter, the remaining shares vest equally on a quarterly basis through December 18, 2013. The sale transaction reported on Table I of the Form 4 filed November 18, 2013 was entered in error. This Amendment is filed to correctly reflect exercise of option occurred on November 14, 2013. This Amendment also corrects the amount of securities beneficially owned to reflect certain adjustments made in connection with a special dividend occurred in 2012.
