F1	Each Performance Stock Unit represents a contingent right to receive one share of Issuer Common Stock.
F2	The Performance Stock Units will cliff vest on the fourth annual anniversary of the grant date, subject to the reporting person's continuing service to the Issuer through the date. The number of shares of Common Stock that will be earned, if any, is determined by a performance multiplier by dividing the average closing price of the Issuer's Common Stock as of the end of the four-year performance period (with a maximum capped at $30.00 per share) by the average closing price of the Issuer's Common Stock as of the beginning of the performance period. In addition, there will be no payout at the end of the performance period if the average share price is below 50% of the average share price as of the beginning of the performance period.
