A person who is an Independent Director immediately following each annual meeting of the Company’s stockholders after the Public Trading Date and who will continue to serve as an Independent Director immediately following such meeting shall be automatically granted such number of shares of restricted common stock on the date of such annual meeting as is determined by dividing (i) $40,000 by (ii) the Fair Market Value per share (as defined in the 2011 Plan) of the Company’s common stock on the date of such grant. The awards described in this subsection (b) shall be referred to as “Subsequent Awards.”

Each Initial Award and each Subsequent Award shall vest and be released from the forfeiture restriction as to one-third of the shares subject to such award on each of the first three anniversaries of the date of grant, subject to the Independent Director continuing in service on the Board through such dates. No portion of an Initial Award or Subsequent Award which is unvested at the time of an Independent Director’s termination of service on the Board shall become vested thereafter. All of an Independent Director’s Initial Awards and Subsequent Awards shall vest in full upon the occurrence of a Change in Control (as defined in the 2011 Plan).
