                                  RULE 8b-25

      The Fund files this Application for Extension of Time pursuant to Rule
8b-25 under the Investment Company Act of 1940, as amended (the "Investment
Company Act") (17 CFR 270.8b-25), respectfully requesting that the date for
the timely filing of its Quarterly Schedule of Portfolio Holdings of
Registered Management Investment Company on Form N-Q ("Form N-Q"), which is
filed pursuant to Rule 30b1-5 under the Investment Company Act, be extended
from December 30, 2006 to February 28, 2007 as provided in Rule 8b-25.

      Due to a recent change in the accounting interpretation of the
presentation in the Fund's financial statements, including its schedule of
portfolio holdings, of investments in tender option bonds or inverse floating
rate bonds, the Fund is not able to finalize the presentation of these
investments in its schedule of portfolio holdings for a timely filing of its
Form N-Q. The Fund's Form N-Q will be completed and filed with the Securities
and Exchange Commission as soon as practicable.

      Rule 8b-25 under the Investment Company Act permits a registered
investment company to file an application for an extension of time if it is
impractical to furnish a required report. The facts and circumstances
described above clearly indicate that it is impractical for the Fund to
furnish a Form N-Q by December 30. Further, the Fund strongly believes that
the requested relief is consistent with the policies and purposes of the
Investment Company Act as well as the protection of investors.

                                    PART II
                               OTHER INFORMATION
