F1 · kind: The sales reported by the Reporting Person were effected pursuant to a Rule 10b5-1 trading plan.

F2 · balance_after: On 8/16/18, the Reporting Person filed a Form 4 to report the sale of 8,312 shares of stock; however, such report incorrectly stated the number of shares held following the transaction. The total amount of securities beneficially owned following the reported transaction was listed as 94,289 shares, inclusive of 8,151 shares previously acquired under an employee stock purchase plan (described in Footnote 2 to such report). In fact, the referenced 8,151 shares were acquired prior to the date on which the Reporting Person became a Section 16 officer and should not have been included in the 8/16/18 report as newly acquired shares. Additionally, as reported on a Form 4 filed on 10/1/19, the share totals in the Reporting Person's Forms 4 prior to 10/1/19 did not reflect the forfeiture of shares in connection with the vesting of certain restricted stock units described therein. As reported in this amendment, the amount of securities beneficially owned on 8/16/18 was in fact 59,867.
