2.  Based on my knowledge, these reports do not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the

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 these reports are 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 these reports 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 these reports any change in the Registrant's internal control
over financial reporting that occurred during the Registrant's most recent
fiscal half-year (the Registrant's second fiscal half-year 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(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.
