        <footnote id="F1">Reflects 351,441 shares withheld by the Issuer at the market price of $4.24 per share less an exercise price of $2.00 per share to (i) fund the cashless exercise of 542,000 options and (ii) pay the amount of any federal, state and/or local income withholding tax arising from such exercise.</footnote>
        <footnote id="F2">Stock options under the Issuer's 1999 Incentive Stock Plan.  The option shares are fully vested.</footnote>
    </footnotes>

    <remarks>The transactions reported in Table I above reflect the cashless exercise of stock options.  The cashless exercise for the options is reported in two (2) lines. The first line of the cashless exercise transaction is coded M in column 3 of Table I above and reports in column 4 the number of shares issuable upon exercise of the options had cash been paid to exercise the options, together with the exercise price with Code A for acquired.  The line coded F in column 3 of Table I above relates to the same cashless exercise on the preceding line and reports in Column 4 the number of shares deducted from the total number of shares issuable to pay for the cashless exercise of such options and tax withholdings associated therewith, such deduction reflected by Code D for disposed.  The number of shares on a net basis actually owned by the Reporting Person after the cashless exercise of the options and the reduction for tax withholdings is the amount by which the first line for each cashless exercise exceed
s the second line for the same cashless exercise.  All transactions are exempt from Section 16(b) by reason of Rule 16b-3.  The transaction reported in Table II above, reflects the disposition of the same stock options whose cashless exercise is disclosed in Table I above.</remarks>
