(1)	These shares were issuable on restricted stock units which forfeited on February 15, 2017 as a result of the non-achievement of 2016 performance goals.
(2)	These shares were withheld by the Company to cover the tax withholding obligations of the executive on the vesting of restricted stock units on February 15, 2017.
(3)	On February 15, 2017, restricted stock units with performance vesting terms granted in May 2016 were determined to have vested as to 60% of the units. The remaining units forfeited. The shares issued to the executive on the vested units were reduced by shares having a value equal to the executive's tax withholding obligation. After these events, of the shares held by the executive as of February 15, 2017, 20,455 were issuable on vesting of other restricted stock units which remain subject to forfeiture.
(4)	Of the shares held as of February 16, 2017, 20,455 were issuable on vesting of restricted stock units granted under the 2012 Equity Incentive Plan and are subject to forfeiture.
