Explanation of responses 3 footnotes
Footnote F1
The sale reported on this Form 4 represents shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. The sale satisfies the tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the Reporting Person.
Footnote F2
This transaction was executed in multiple trades at prices ranging from $18.06 USD to $18.37 USD; the price reported above reflects the weighted average sale price. The Reporting Person undertakes to provide Issuer, any security holder of the Issuer, or the Staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.
Footnote F3
Includes 124,139 shares issuable on the settlement of restricted stock units granted to the Reporting Person. Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
