Based on my knowledge, this report does not contain
  any untrue statement of a material fact or omit to state a material fact

  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 cash
  flows of the registrant as of, and for, the periods presented in this report;4.
The registrants other certifying officer and I are
  responsible for establishing and maintaining disclosure controls and  procedures (as defined in Exchange Act
  Rules 13a-15(e) and 15d-15(e)) for the 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 the
  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 controls over financial
  reporting, or caused such internal controls 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 principals;(c) Evaluated the effectiveness of the 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 the
  registrants internal control 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; and5.
The registrants other certifying officer and I have

  financial reporting, to the registrants auditors and the audit committee of
  the 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 which are reasonably likely to adversely affect the 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 the
  registrants internal control over financial reporting.  Date:
