This option becomes exercisable in 4 equal quarterly installments beginning on November 7, 2011. The corresponding footnote to the reporting person's original Form 3 incorrectly stated that this option was currently exercisable as to 26,931 shares of common stock; this option was exercised for such 26,931 shares of common stock prior to the filing of the reporting person's original Form 3. 26,931 shares of common stock subject to this option were inadvertently included in Table II of the reporting person's orginal Form 3, and were omitted from Table I of the reporting person's original Form 3. The reporting person's original Form 3 did not reflect his exercise of an option for 26,931 shares of common stock. /s/ Danielle Sheer, by power of attorney 2012-01-11
