        <footnote id="F1">Since the date of the reporting person's last report prior to July 10, 2015, 11,919 shares previously held through the OPC Savings Plan were distributed into an individual account and, therefore, are now owned directly by the reporting person. These shares were omitted from the total holdings in line 2 of table I of the reporting person's original Form 4 filed on July 10, 2015 and, as such, the total holdings are corrected herein.</footnote>
