Since the Annual Grant RSUs are payable solely in common stock, they are being reported in Table I of this Form 4. The Annual Grant RSUs vest on the earlier of the first anniversary of the grant date or the date of the Issuer's 2019 annual meeting of the stockholders, but the underlying shares will not be issued until the earlier of the Reporting Person's death or the first day of the seventh month following the Reporting Person's retirement from the Board of Directors of the Issuer.</footnote>
