 Effective January 1, 2005, the annual incentive range for bonus awards for Named Executive
Officers for 2005 was set at between zero and sixty percent of base salary with the target set at
fifty percent of base salary for each Named Executive Officer except Mr. Wiggans. The range and
target bonus for Mr. Wiggans for 2005 will be set at the discretion of the Board of Directors. The
metrics to be used for measurement for bonus awards for 2005 include the Companys success in
achieving specific company-wide goals as well as the Named Executive Officers success in achieving
individual and department goals in 2005. On January 18, 2005, the Compensation Committee also approved grants of ten-year
stock options to each of the Named Executive Officers. The factors considered in
making these option grants included individual performance and potential, as well as individual and
company performance. Mr. Wiggans recommended the number of options for each annual grant (other
than for himself), generally within the target range associated with the individuals position and
salary level. The following table sets forth the option grants approved by the Committee:
