Due to a clerical error, the original Form 4 filed on January 3, 2020 listed the incorrect number of securities in columns 5, 7 and 9 of Table II.
The shares of common stock underlying this stock option award vest as to 25% of the shares on the first anniversary of January 1, 2020 and the remaining shares vest in equal quarterly installments over the following three years thereafter.
As noted in footnote 1, this Form 4/A amends the Form 4 filed on January 3, 2020 for this reporting person.
