[2] Restricted Stock Units (“RSUs”) were primarily granted in connection with the 2017-2018 LTIP. The RSUs will vest in two tranches with the first 50% vesting on April 1, 2019 and the second 50% vesting on April 1, 2020.

[3] The 43,467 shares of deferred stock, with a fair value of $121,612, represent compensation to certain directors in lieu of cash, in accordance with their irrevocable elections. The shares of deferred stock will vest three years from the date of grant or at separation of service, based on the irrevocable election of each director.

[4] During the first six months of fiscal 2017, the Company granted 40,109 shares of stock, with a fair value of approximately $115,018, to certain directors as compensation in lieu of cash, in accordance with their irrevocable elections.
