Explanation of Responses:

( 1 )Each restricted stock unit represents a contingent right to receive one share of the issuer's common stock. ( 2 )On the Form 4 filed by the reporting person on January 3, 2019, the amount of shares acquired by the reporting person in the transaction reported in that Form 4 related to the acquisition of shares under the ESPP, and the amount of securities beneficially owned by the reporting person following such acquisition, were both overstated by 37. The amount reported in this Column 5 reflects a reduction of 37 shares to correct this error. ( 3 )These shares were withheld by the issuer to satisfy statutory tax withholding requirements on vesting of restricted stock units that occurred on January 1, 2020. No shares were sold in connection with this transaction. ( 4 )The reporting person was granted 46,720 restricted stock units on February 2, 2017, which vest in three equal installments on each of January 1, 2018, 2019 and 2020. ( 5 )The reporting person was granted 35,656 restricted stock units on March 5, 2018, which vest in three equal installments on each of January, 1, 2019, 2020 and 2021. ( 6 )The reporting person was granted 10,125 restricted stock units on January 1, 2019, which vest in three equal installments on each of January 1, 2020, 2021, and 2022. ( 7 )The restricted stock units vest in three equal installments on each of January 1, 2021, 2022 and 2023. ( 8 )The option vests as to 25% of the underlying shares on January 1, 2021 and the remaining 75% in twelve substantially equal quarterly installments thereafter.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
