Meglasson 292,000 Tod G. Mertes 260,000 Also on April 6, 2006, the Compensation Committee authorized the payment of annual incentive (bonus) awards to each of the Company's executive officers for services during the year ended December 31, 2005. Consistent with past practice, the Compensation Committee used several factors to set the targets for these annual incentive awards, principally (1) competitive pay practices, (2) job duties and responsibility and (3) the Company's need to attract, retain and reward executive talent. The Compensation Committee used data obtained by the Company from external sources that compared and summarized pay practices at companies that compete with the Company nationally and in its business and location for executive talent. Actual annual incentive bonus payments were determined based on the Company's and each executive's performance during 2005 as measured against performance measures established for that year. In addition, the Compensation Committee evaluated each executive's performance against individual goals also set for 2005. The following table sets forth cash payments to the executive officers in respect of their annual incentive awards for 2005: Name 2005 Bonus David E. Robinson $150,000 Andres F.

Mertes 48,000 Amendment to Management Bonus Plan On April 7, 2006, the Compensation Committee approved an amendment to the Company's Management Bonus Plan applicable to executives, including the executive officers of the Company. The amendment was made in order to maintain a Bonus Plan that is competitive with market compensation. Under the amendment, the maximum bonus payout applicable to executive officers, other than the Chief Executive Officer, under the plan was increased from 36% of base salary to 50% of base salary. The maximum bonus payout for the Chief Executive Officer was established at 60% of base salary. Actual payouts are based on the Company's and each executive's performance during the fiscal year, as measured against performance measures established for that year. Company performance and individual performance are equally weighted in determining payouts.
