     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;

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

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

4.   The registrant's other certifying officers and I are
     responsible for establishing and maintaining disclosure

     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 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 officers 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.
