        <footnote id="F1">The purpose of this Amendment filing is to reflect that on January 1, 2011, the reporting person became subject to Troubled Asset Relief Program restricted stock guidelines, and therefore her previous grant of 10,000 Performance Units may be reduced by up to 3,263 Performance Units.  Each Performance Unit represents the contingent right to receive one share of NARA common stock.</footnote>
        <footnote id="F2">Subject to the Troubled Asset Relief Program restricted stock guidelines, the previous vesting schedule is revised so the Performance Units will vest two-fifths on May 3, 2012, and the remaining three-fifths will vest in three equal installments on May 3, 2013, 2014, and 2015.</footnote>
