Explanation of Responses:

1. Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of Issuer's Common Stock.

2. Includes 676 shares acquired under the Issuer's Employee Stock Purchase Plan ("ESPP") on July 31, 2017 and 435 shares acquired under the ESPP on January 31, 2018, each in a transaction exempt under Rule 16b-3.

3. Represents number of shares of Issuer's Common Stock withheld to satisfy the Reporting Person's tax obligations in connection with the vesting of 2,000 shares of Common Stock underlying the Reporting Person's RSUs.

4. On August 11, 2017, the Reporting Person was granted 15,000 RSUs, which vest in installments upon the achievement of specified market capitalization milestones of the Issuer on or before December 31, 2019, so long as the Reporting Person continues as an employee or other service provider of the Issuer through each vesting milestone. On February 14, 2018, one of the performance milestones was achieved, resulting in the vesting of 2,000 shares of Common Stock underlying the RSU grant. The RSUs are subject to accelerated vesting upon termination without cause or resignation for good reason after a change of control of the Issuer.
