2.      Based on my knowledge, this annual 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 annual report;

3.      Based on my knowledge, the financial statements, and other financial
        information included in this annual report, fairly present in all

        annual report;

4.      The registrant's other certifying officers and I are responsible for
        establishing and maintaining the disclosure controls and procedures (as
        defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant and
        have:

        a)      designed such disclosure controls and procedures 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
                annual report is being prepared;

        b)      evaluated the effectiveness of the registrant's disclosure
                controls and procedures as of a date within 90 days prior to the
                filing date of this annual report (the "Evaluation Date"); and

        c)      presented in this annual report our conclusions about the

                our evaluation as of the Evaluation Date;

5.      The registrant's other certifying officers and I have disclosed, based
        on our most recent evaluation, 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 in the design or operation of internal
        controls which could adversely affect the registrant's ability to
        record, process, summarize and report financial data and have identified
        for the registrant's auditors any material weaknesses in internal
        controls; and

b)      any fraud, whether or not material, that involves management or other
        employees who have a significant role in the registrant's internal
        controls; and

6.      The registrant's other certifying officers and I have indicated in this
        annual report whether there were significant changes in internal
        controls or in other factors that could significantly affect internal
        controls subsequent to the date of our most recent evaluation, including
        any corrective actions with regard to significant deficiencies and
        material weaknesses.
