Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report. Management recognizes that any system of disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance rather than absolute assurance of achieving its objectives. The design of a control system must reflect resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation can provide absolute assurance that all control issues or instances of fraud, if any, will be detected. These inherent limitations include the possibility of faulty judgments, errors or mistakes, and the potential for controls to be circumvented by individual acts, collusion among employees, or management override. Moreover, the design of any control system is based on certain assumptions regarding future events, and there is no guarantee that any design will succeed under all potential future conditions. Over time, controls may become inadequate due to changes in conditions or deterioration in compliance with policies or procedures. Consequently, misstatements due to error or fraud may occur and not be detected. Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
