over financial reporting (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the registrant and have:

(a) Designed such disclosure
controls and procedures, or caused such disclosure controls and procedures to be

others within those entities, particularly during the period in which this
report is being prepared;

internal control over financial reporting; and

and material weaknesses in the design or operation of internal control over

information; and

material, that involves management or other employees who have a significant
role in the registrants internal control over financial reporting.
