        <footnote id="F1">Represents the number of restricted stock units granted to the Reporting Person on January 3, 2011 as part of the Registrant's 2007 Stock Incentive Program. The restricted stock units vest in one lump sum upon the completion of the three-year period ending January 3, 2014. In the event the services of the Reporting Person cease prior to the expiration of such three-year period, the restricted stock units will vest upon such 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>
        <footnote id="F2">Represents (i) 35,996 shares of common stock, (ii) 10,000 restricted stock units previously granted to the Reporting Person on March 18, 2010 and (iii) 10,000 restricted stock units granted to the Reporting Person on January 3, 2011 which will vest as set forth in note 1.</footnote>
