|3. | Based on my knowledge, the financial statements, and other financial information

| | a) | designed such disclosure controls and procedures, or caused such disclosure
                    controls and procedures to be designed under our supervision, to ensure that
                    material information relating to the registrant, including its consolidated
                    subsidiaries, is made known to us by others within those entities, particularly

                    over financial reporting that occurred during the period covered by the annual
                    report that has materially affected, or is reasonably likely to materially
                    affect, the registrants internal control over financial reporting; and
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

          our most recent evaluation of internal control over financial reporting, to the

          directors (or persons performing the equivalent function):
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) | all significant deficiencies in the design or operation of internal control over
                    financial reporting which are reasonably likely to adversely affect the
                    registrants ability to record, process, summarize and report financial
                    data information; and
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) | any fraud, whether or not material, that involves management or other employees
                    who have a significant role in the registrants internal control over
