|
2. |
Based
on my knowledge, this quarterly report does not contain any untrue

|
4. |
The
company's other certifying officer and I are responsible for establishing
and maintaining disclosure controls and procedures (as defined in Exchange
Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for
the company and we have: |
|
i. |
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 company, including its
consolidated subsidiaries, is made known to us by others within those
entities, particularly during the period in which this quarterly report is
being prepared; |
|
ii. |

principles; |

process, summarize and report financial information;
and |
|
ii. |
any
fraud, whether or not material, that involves management or other
employees who have a significant role in the company's internal control
