      Registrant’s other certifying officer and I are responsible for establishing and
      maintaining disclosure controls and procedures (as defined in Exchange Act

      reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for
      registrant 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 material information relating to registrant, including its
              consolidated subsidiaries, is made known to us by others within those
              entities, particularly during the 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;
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|c) | Evaluated
              the effectiveness of registrant’s disclosure controls and procedures and
              presented in this report our conclusions about the effectiveness of
              the
              disclosure controls and procedures, as of the end of the period covered
              by
              this report based on such evaluation; and
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




|d) | Disclosed
              in this report any change in registrant’s internal control over financial
              reporting that occurred during registrant’s most recent fiscal quarter
              that has materially affected, or is reasonably likely to materially
              affect, registrant’s internal control over financial reporting;
              and
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




5.
      Registrant’s other certifying officer and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to registrant’s
      auditors and the audit committee of 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 that are reasonably
              likely to adversely affect 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 registrant’s internal control
