| 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)    | Designed such      internal control over financial reporting, or caused such internal control      over financial reporting to be designed under our supervision, to provide      reasonable assurance regarding the reliability of financial reporting and      the preparation of financial statements for external purposes in      accordance with generally accepted accounting principles;  |

|----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| a)    | All significant      deficiencies and material weaknesses 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 information; and  |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
