        <footnote id="F1">Grant of restricted stock units under the Company's 2013 Omnibus Incentive Plan. Each restricted stock unit represents the contingent right to receive one share of the Company's common stock, par value $0.01 per share. The restricted stock units vest on the earliest of: (1) the one year anniversary of the grant date, (2) the Company's next annual shareholders meeting, or (3) a change in control, and will be settled upon vesting unless the reporting person elects to defer settlement to a later date. A pro rata portion of the award vests upon termination of the reporting person's service due to death, disability or age 75 retirement.</footnote>
