Great Southern, like many financial institutions, has from time to time extended loans to its officers, directors and employees, generally for the financing of their personal residences, at favorable interest rates. Generally, residential loans have been granted at interest rates 1% above Great Southern's cost of funds, subject to annual adjustments. Other than the interest rate, these loans have been made in the ordinary course of business, on substantially the same terms and collateral as those of comparable transactions prevailing at the time, and, in the opinion of management, do not involve more than the normal risk of collectibility or present other unfavorable features. All loans by Great Southern to its directors and executive officers are subject to regulations restricting loans and other transactions with affiliated persons of Great Southern. Great Southern may also grant loans to officers, directors and employees, their related interests and their immediate family members in the ordinary course of business on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons which, in the opinion of management, do not involve more than the normal risk of collectibility or present other unfavorable features.

No directors, executive officers or their affiliates, had aggregate indebtedness to Great Southern on below market rate loans exceeding $60,000 at any time since January 1, 2005 except as noted below. (See page 7 for table).
