registrants' other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange

15d-15(f)) for the registrants and have:
- (a)
- Designed
such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that

being prepared;

quarter (the registrants' fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrants' internal control over
financial reporting; and
- 5.
- The
registrants' other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the
registrants' auditors and the audit committee of the registrants' 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 registrants' 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 registrants' internal control over
financial reporting.
