    <TD>In the first quarter of each year, the Personnel and Compensation Committee
meets to determine whether, based on overall company performance, individual performance,
competitive compensation and target total compensation, base salaries for the named executive
officers should be increased. Additionally, base salaries for the named executive officers
will generally increase concurrent with an officer&#146;s promotion or an increase in an officer&#146;s
responsibilities, as may be determined by the Personnel and Compensation Committee from time
to time and recommended to the Board of Directors for approval.</TD>

    <TD>The Company also provides certain other benefits to its executive officers that are
not tied to any formal individual or corporate performance objectives and are intended to be
part of a competitive overall compensation program. For example, the Company maintains an
employee thrift plan, a cash balance pension plan, insurance and other benefit plans for its
employees. Executive officers participate in these plans on the same terms as other eligible
employees, subject to any legal limits on the amounts that may be contributed by or paid to
executives under the plans. In addition, the Company reimburses certain executive officers
for financial planning services and club dues, and the Company also pays certain executive
officers an additional amount sufficient to compensate him or her for the taxes arising as a
result of the perquisites the Company provides.</TD>
