(1) Represents the number of shares sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. This sale is 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 does not represent a discretionary trade by the Reporting Person.
(2) The price reported in Column 4 is a weighted average price calculated by the broker. These shares were sold as part of a block trade in multiple transactions at prices ranging from $16.49 to $17.12, inclusive. The Reporting Person undertakes to provide to the 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 (2) with regard to the block trade.
(3) Shares held of record by the Kevin R. Mandia 2011 Irrevocable Trust Dated July 29, 2011 (the "Irrevocable Trust"). The Reporting Person's spouse, as trustee, has shared voting and investment power with respect to the shares held of record by the Irrevocable Trust. The Reporting Person disclaims beneficial ownership of such shares.
(4) Shares held of record by the Reporting Person's spouse. The Reporting Person disclaims beneficial ownership of the shares held by his spouse, and this report should not be deemed an admission that the Reporting Person is the beneficial owner of his spouse's shares for purpose of Section 16 or for any other reason.
