reliability of financial reporting                     and the preparation of financial
statements for external purposes in accordance                     with generally

                    over financial reporting that occurred during the registrants
most recent                     fiscal quarter (the registrants fourth fiscal
quarter in the case of an                     annual report) that has materially
affected, or is reasonably likely to                     materially affect, the registrants
internal control over financial                     reporting; and

|5. | The
registrants other certifying officer(s) and I have disclosed, based on
                    our most recent evaluation of internal control over financial
reporting, to the                     registrants auditors and the audit committee

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

fraud, whether or not material, that involves management or other employees
