        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of the issuer's common stock.</footnote>
        <footnote id="F2">The grant reported on this Form 4 excludes the grant by the issuer to the reporting person on December 2, 2014 of up to 19,830 restricted stock units that will vest based on the achievement by the issuer of a specified revenue-based performance target and up to 15,512 restricted stock units that will vest based on the achievement of a specified total shareholder return target, in each case subject to the continued employment of the reporting person with the issuer.</footnote>
        <footnote id="F3">25% of the restricted stock units will vest on December 2, 2015, and an additional 6.25% of the restricted stock units will vest quarterly thereafter, such that 100% of the restricted stock units will be fully vested on December 2, 2018.
