(1) For Mr. Kenningham, the amounts in this column reflect the cash payments and acceleration value of equity award benefits that would become payable upon a qualifying termination following a Corporate Change.

(3) Mr. Kenningham could receive up to 120 days of continued base salary ($410,959) in the event that he is deemed disabled.
