        <footnote id="F1">Represents a deferred stock award of 14,400 restricted stock units which vest quarterly in equal installments on March 31, 2016, June 30, 2016, September 30, 2016 and December 31, 2016, and are subject to continued service as a non-employee director on the applicable vesting dates.  These retainer awards are granted in lieu and satisfaction of the annual cash retainer compensation to be earned by the director for his service on the Issuer's Board of Directors and its Committees during 2016. 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 retainers all been paid in cash, divided by the average daily closing market price of the Issuer's common stock for the month of November, rounded to the nearest 100 shares.</footnote>
        <footnote id="F2">Includes (a) a deferred stock award of 14,400 restricted stock units which fully vest on the earlier of (i) the date of the Issuer's next Annual Meeting of Stockholders after June 4, 2015, immediately prior to the commencement of such meeting, and (ii) June 4, 2016; (b) a deferred stock award of 14,400 restricted stock units which vest quarterly in equal installments on March 31, 2016, June 30, 2016, September 30, 2016 and December 31, 2016; and (c) 71,010 shares of common stock held by the Reporting Person.</footnote>
