Explanation of responses 4 footnotes

Footnote F1

Represents previously issued restricted stock units that the Issuer retired for cash upon vesting in lieu of issuing shares of common stock.

Footnote F2

These restricted stock units were settled by the Issuer at the closing price per share of the Issuer's common stock on the vesting date.

Footnote F3

The sales reported on this Form 4 represent shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting and settlement of restricted stock units. These sales are mandated by the Issuer's election under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.

Footnote F4

The price reported is a weighted average price. These shares were sold in multiple transactions at prices ranging from $15.82 to $15.83, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth herein.
