Appendix

Consolidated Statements of Operations (1) Pursuant to GAAP, the Company is required to present earnings per share "as if" all earnings were distributed to Common and Preferred Shareholders. Under this "two class" method, earnings are allocated to Common and Preferred Shareholders in proportion to their respective ownership interests. This calculation would allocate approximately 70% of the current earnings to Common Shareholders and yield $0.06 earnings per share per Common Shareholder, as shown above. However, the Company has not in the past, and does not currently intend to, declare a distribution of earnings. Absent this "as if" apportionment, earnings per Common share would be $0.08. The Company will be filing a 10-Q/A for the first quarter ended March 31, 2003, reflecting this "two class" method. (in thousands)
