        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of WTI common stock or its cash equivalent, as determined at the time of settlement by WTI.</footnote>
        <footnote id="F2">The vesting of the restricted stock units is subject to service and performance conditions during calendar year 2016, and a service condition thereafter until December 14, 2018. If these conditions are met, then the restricted stock units will vest on December 14, 2018. The number of restricted stock units eligible for vesting is subject to adjustment to reflect the achievement of performance goals by the reporting person during the applicable performance period.</footnote>
