Footnotes

F1: This amendment is being filed to correct the total securities benefically owned in Column 5 from the original Form 4 filing on February 22, 2012. 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 filing filed on February 22, 2012.
