Reconciliation Table for Third Quarter 2003 Earnings Conference Call

"EBITDA" is defined as income before income tax expense and minority interest, depreciation, interest income, interest expense and amortization. EBITDA is not intended to represent cash flow from operations as defined by generally accepted accounting principles and should not be considered as an alternative to net income as an indicator of operating performance or to cash flows as a measure of liquidity. EBITDA is presented as the Company understands that certain investors use it as one measure of a borrower's historical ability to service its debt.
