The RSUs vest in equal portions over a 3 year period and are received by the reporting person upon vesting unless the reporting person has previously elected a longer deferral period. This report reflects the vesting of the first one-third of these RSUs, the acquisition by the reporting person of the underlying shares and the withholding by the issuer of sufficient shares to pay income taxes required to be withheld from the reporting person. The fair market value of the shares, based on the closing price of the issuer's stock on February 17, 2006 (last business day before shares vested) is $28.40. Alan J.
