|  
|2. |  | Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact
necessary to make the statements made, in light of the circumstances
under which such statements were made, not misleading with respect to
the period covered by this report;
|  
|3. |  | Based on my knowledge, the financial statements, and other
financial information included in this report, fairly present in all
material respects the financial condition, results of operations and

|

for establishing and maintaining disclosure controls and procedures
(as defined in Exchange Act Rules 13a-14 and 15d-14) for the

| | a) |  | 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

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 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 of
registrants board of directors (or persons performing the equivalent
function):
|-- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

information; and

|
| | b) |  | Any fraud, whether or not material, that involves
management or other employees who have a significant role in the
