Footnotes

F1: On November 8, 2012, the reporting person transferred 11,998 shares from direct holdings to the trust. The Form 4 filed on May 8, 2013 incorrectly disclosed that 1,250 shares were transferred from direct holdings to the trust on that date, omitting the transfer of an additional 10,748 shares on that date. As a result, the Form 4s filed by the reporting person on May 17, 2013 and October 17, 2013 do not reflect the full number of shares transferred to the trust. This transfer was exempt from reporting pursuant to Rule 16a-13 under the Securities and Exchange Act of 1934.
