| | <footnote id="F1"> Represents gift of shares to four adult children. </footnote> |
| | <footnote id="F2"> Represents the number of restricted stock units granted to the Reporting Person on January 2, 2013 as part of the Registrant's 2007 Stock Incentive Program. The restricted stock units vest upon the completion of the three-year period ending December 31, 2015. In the event that the services of the Reporting Person cease prior to the expiration of such three-year period, the restricted stock units will vest upon the cessation of service, provided however that the number of restricted stock units that vest will be reduced pro rata to the extent of the portion of the three-year period not served. Each restricted stock unit represents a right to receive one share of the Registrant's common stock. </footnote> |
