Footnote F3

Represents a grant of RSUs that may be earned based on the achievement of market price goals, which will be measured as the average closing price of issuer's common stock over any ten consecutive trading day period beginning with the first anniversary of the award. 100% of the number of RSUs will be earned if the measured market price is $5.25 or above.
