        <footnote id="F1">Grant of restricted stock which lapses in 20% increments on March 1, 2007, 2008, 2009, 2010 and 2011 unless reporting person is not an employee on the applicable date.  Any restricted stock which has not lapsed is forfeited.  Notwithstanding the above, if reporting person is an employee on the occurrence or deemed occurrence of a change in control, all restricted stock shall lapse.</footnote>
        <footnote id="F2">Also includes shares acquired by reporting person under the issuer's 401(k) plan since last reported on Form 4.</footnote>
        <footnote id="F3">Also includes shares acquired by reporting person under the issuer's Employee Stock Purchase Plan since last reported on Form 4.</footnote>
        <footnote id="F4">Options become exercisable in 20% increments on each of March 1, 2007, 2008, 2009 2010 and 2011.</footnote>

    <remarks>In the June 14, 2005 Form 4, the grant of the restricted stock was for $0, and with respect to the employee stock option (right to buy), column 8 disclosed a price of $14.70, but should have disclosed a price of $0.</remarks>
