registrant’s certifying officer, I am responsible for establishing and
maintaining disclosure controls and procedures (as defined in Exchange Act Rules

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

material information relating to the registrant, including its consolidated
subsidiaries, is made known to me by others within those entities, particularly
during the period in which this report is being prepared;

registrant’s internal control over financial reporting; and

registrant’s certifying officer, I have disclosed, based on my most recent
evaluation of internal control over financial reporting, to the registrant’s
auditors and the audit committee of the registrant’s board of directors (or
persons performing the equivalent functions):





(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





(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.
