|(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 Company, including its

                  period in which this report is being prepared;
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) |  | Designed such internal control over financial reporting, or caused such internal control over financial
                  reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability
                  of financial reporting and the preparation of financial statements for external purposes in accordance
                  with generally accepted accounting principles;

|(d) |  | Disclosed in this report any change in the Company's internal control over financial reporting that
                  occurred during the Company's most recent fiscal quarter (the Company's fourth fiscal quarter in the case
                  of an annual report) that has materially affected, or is reasonably likely to materially affect, the
                  Company's internal control over financial reporting; and
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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