        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.

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 is made known to us by others within the
                 Registrant, particularly during the period in which this report
                 is being prepared;

        b.       [intentionally omitted];

        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 evaluations; 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; 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 the Registrant's Board of
Directors (or persons performing the equivalent functions):

        a.       all significant deficiencies in the design or operation of
                 internal controls 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.
