        <footnote id="F1">Represents a deferred stock award of 6,500 restricted stock units which vest quarterly in equal installments on September 30, 2017 and December 31, 2017. This retainer award was granted in lieu and satisfaction of the annual cash retainer compensation to be earned by the director for his service on a committee of the Issuer's Board of Directors that the reporting person was appointed to following the 2017 annual meeting of stockholders. The number of shares of common stock subject to such retainer award is equal to the amount of cash that would have been received had the applicable retainer all been paid in cash, divided by the average daily closing market price of the Issuer's common stock for the month of April, rounded to the nearest 100 shares.</footnote>
        <footnote id="F2">Includes (a) a deferred stock award of 31,300 restricted stock units which fully vest on the earlier of (i) the date of the Issuer's next Annual Meeting of Stockholders after May 18, 2017, immediately prior to the commencement of such meeting, and (ii) May 18, 2018; (b) a deferred stock award of 14,800 restricted stock units which vest quarterly in equal installments on September 30, 2017 and December 31, 2017; and (c) 70,612 shares of common stock held by the Reporting Person.</footnote>
