        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 the report;

    3.  Based on my  knowledge,  the schedules on  investments  included in this
        report fairly  present in all material  respects the  investments of the
        registrant  as of the end of the fiscal  quarter for which the report is
        filed;

        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 most recent fiscal quarter 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 control over financial reporting.
