Footnotes

On February 4, 2014, the reporting person was granted a target of 37,208 shares of restricted stock units subject to satisfaction of pre-determined, performance-based vesting criteria. On February 2, 2016, the Company's Board of Directors determined that those performance criteria for the restricted stock units had been satisfied, which resulted in 65,114 additional shares being achieved and granted to the reporting person. Of the restricted stock units that were awarded, 51,161 will vest immediately and 51,161 will vest quarterly in the next two years.
The reported sales were to cover taxes upon the vesting of restricted stock units, as required by the Company's equity incentive plans.
1/16 of the Restricted Stock Units shall vest quarterly following the Vesting Commencement Date, provided that the Grantee continues to be a Service Provider from the Grant Date through each applicable vesting date.
