|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

 

|   | 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 during the period in                            which this report is being prepared; |

|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

 

|   | 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 financial                            reporting. |
