Explanation of Responses:

( 1 )Includes 1,183.3136 shares acquired (including 17.8591 shares acquired by dividend reinvestment) pursuant to the Company's Employee Stock Purchase Plan. ( 2 )Due to a clerical error, all options were previously erroneously reported as having been exercised on the Form 4 filed on May 11, 2016, when in fact the option remained unexercised solely with respect to 20 shares. The option was exercised with respect to those remaining 20 shares on August 18, 2017 prior to the option's expiration on August 20, 2017. ( 3 )All of these options are currently exercisable. ( 4 )29,163 of these options are currently exercisable and the remaining 9,721 options become exercisable on February 27, 2018, assuming continued employment through the applicable vesting date. ( 5 )Each restricted stock unit is convertible into a share of common stock on a 1-for-1 basis. ( 6 )These restricted stock units remain subject to a time-vesting requirement and are scheduled to vest and settle in common stock as follows: one-third of these restricted stock units vested on February 20, 2016, one-third of these restricted stock units vested on February 20, 2017 and the remaining one-third of these restricted stock units vest on February 20, 2018, assuming continued employment through the applicable vesting date.
