(2) Includes 301 shares of Common Stock, 5,508 shares of Common Stock held under an IRA account, 516 shares underlying restricted stock units and 487 shares of deferred stock which may be subject in whole or in part to vesting schedules tied to the reporting person?s continued service with the issuer and which will be distributed as actual shares of Common Stock of the issuer either at the time of vesting or at a specified time thereafter (including termination of service with the issuer).
(3) The Stock options are exercisable according to the vesting schedule. The shares vest in four successive equal annual installments upon Mr. Belhumeur's completion of each year of service with the issuer over a four-year period measured from the April 29, 2003 issue date of the stock options. Therefore 532 shares of Common Stock of the issuer became exercisable on April 29, 2004 and on April 29, 2005 and 533 shares of Common Stock became exercisable on April 29, 2006 and on April 29, 2007. The exercise price is $14.00 per share.
