Policy Statement

We have a policy whereby all transactions between us and our officers, directors and affiliates will be on terms no less favorable to us than could be obtained from unrelated third parties. These transactions must be approved by the Audit Committee of our Board of Directors. The transactions set forth below were conducted under application of this policy and we believe were no less favorable to us than we would have obtained in an arms length transaction with an unaffiliated third party.
