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

        include a statement of cash flows) of the registrant as of, and for, the
        periods presented in this report;

4.      The registrant's other certifying officer(s) and I are responsible for
        establishing and maintaining disclosure controls and procedures (as
        defined in Rule 30a-3(c) under the Investment Company Act of 1940) and
        internal control over financial reporting (as defined in Rule 30a-3(d)
        under the Investment Company Act of 1940) 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 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 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 a date within 90 days prior to the filing
                date of 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 second fiscal quarter of the period covered by this
                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(s) and I have disclosed 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.
