        <footnote id="F1">This amount includes 13,680 shares held jointly with the reporting person's wife and 322 shares held in the reporting person's IRA.  Also, see note (d) below.</footnote>
        <footnote id="F2">The reported amount includes the ESOP 2003 year-end distribution of 1,788 shares (pre-stock split) of common stock to the reporting person's ESOP participant account.  This distribution was effectuated in mid-May 2004.  The reported amount also reflects the transfer of 11,208 shares (pre-stock split) of common stock from the ESOP participant account to the reporting person.  This transfer occurred during February 2004.  Also, see note (d) below.</footnote>
        <footnote id="F3">The stock option and stock appreciation right become exercisable to the extent of 20% on the above date and is cumulatively exercisable to the extent of 20% each year thereafter.  The stock appreciation right and the stock option were granted in tandem.  Accordingly, the exercise of the one results in the expiration of the other, if and to the extent the other is not exercised.  Also, see note (d) below.</footnote>
        <footnote id="F4">The amounts of securities disclosed in Table I and Table II of this Form 4 have been adjusted since the filing of the last Form 4 on behalf of the reporting person in order to reflect a 2-for-1 stock split of the Company's common stock that became effective on April 14, 2004.  Also, see note (d) below.</footnote>
