Unvested shares are subject to acceleration upon the occurrence of certain events.

4. 1/4th of the shares issuable pursuant to the restricted stock units shall vest one year after the vesting commencement date of January 15, 2018 and an additional 1/48th of the shares issuable pursuant to the restricted stock units shall vest each month thereafter, subject to the Reporting Person's continuous service to the Issuer on each such date.
