The Rule 10b5-1 trading plan is a pre-arranged written trading plan pursuant to which shares of the Issuer's common stock are sold automatically based on a predetermined formula that was established by the Reporting Person at a time when the Reporting Person was not aware of any material nonpublic information about the Issuer.</footnote>
