Footnotes

F1: This amendment is being filed to correct the total securities beneficially owned in Column 5 from the original Form 4 filing on December 22, 2011. No changes have been made to the reported purchases. This correction was previously filed via Form 4 on April 23, 2012, but the filing was inadvertently filed as a new form 4 and not as an amendment to the Form 4 filed on December 22, 2011.
