   (c)      Floating Rate Note Obligations Related to Securities Held - The
            Trust enters into transactions in which it transfers to Dealer
            Trusts ("Dealer Trusts"), fixed rate bonds in exchange for cash and
            residual interests in the Dealer Trusts' assets and cash flows,
            which are in the form of inverse floating rate investments. The
            Dealer Trusts fund the purchases of the fixed rate bonds by issuing
            floating rate notes to third parties and allowing the Trust to
            retain residual interest in the bonds. The Trust enters into
            shortfall agreements with the Dealer Trusts which commit the Trust
            to pay the Dealer Trusts, in certain circumstances, the difference
            between the liquidation value of the fixed rate bonds held by the
            Dealer Trusts and the liquidation value of the floating rate notes
            held by third parties, as well as any shortfalls in interest cash
            flows. The residual interests held by the Trust (inverse floating
            rate investments) include the right of the Trust (1) to cause the
            holders of the floating rate notes to tender their notes at par at
            the next interest rate reset date, and (2) to transfer the municipal
            bond from the Dealer Trusts to the Trust, thereby collapsing the
            Dealer Trusts. The Trust accounts for the transfer of bonds to the
            Dealer Trusts as secured borrowings, with the securities transferred
            remaining in the Trust's investment assets, and the related floating
            rate notes reflected as trust liabilities. The notes issued by the
            Dealer Trust have interest rates that reset weekly and the floating
            rate note holders have the option to tender the notes to the Dealer
            Trust for redemption at par at each reset date. At January 31, 2007,
            Trust investments with a value of $15,199,705 are held by the Dealer
            Trust and serve as collateral for the $11,057,315 in floating rate
            note obligations outstanding at that date. Contractual maturities of
            the floating rate note obligations and interest rates in effect at
            January 31, 2007 are presented in the "Portfolio of Investments".

ITEM 2.  CONTROLS AND PROCEDURES.

(a) The Trust's principal executive officer and principal financial officer have
concluded that the Trust's disclosure controls and procedures are sufficient to
provide reasonable assurance that information required to be disclosed by the
Trust in this Form N-Q was recorded, processed, summarized and reported within
the time periods specified in the Securities and Exchange Commission's ("SEC")
rules and forms, based upon such officers' evaluation of these controls and
procedures as of a date within 90 days of the filing date of the report. The
Trust's principal executive officer and principal financial officer have also
concluded that the Trust's disclosure controls and procedures designed to ensure
that information required to be disclosed by the Trust in this Form N-Q is
accumulated and communicated to the Trust's management, including its principal
executive officer and principal financial officer, as appropriate to allow
timely decisions regarding required disclosure were effective.

Management of the Trust has determined that as of and prior to January 31, 2007,
the Trust's fiscal quarter end period, the Trust had a deficiency in its
internal control over financial reporting related to the review, analysis and
determination of whether certain transfers of municipal securities qualified for
sale accounting under the provisions of Statement of Financial Accounting
Standards No. 140 "Accounting for Transfers and Servicing of Financial Assets
and Extinguishments of Liabilities." Since January 31, 2007 and prior to the
issuance of the Fund's quarterly schedule of portfolio holdings, management has
revised its disclosure controls and procedures and its internal control over
financial reporting in order to improve the controls' effectiveness to ensure
that transactions in transfer of municipal securities are accounted for
properly.

Management notes that other investment companies investing in similar
investments over similar time periods had been accounting for such investments
in a similar manner as the Trust. Accordingly, other investment companies are
also concluding that there was a material weakness in their internal control
over financial reporting of such investments. There was no impact to the net
asset value of the Trust's shares or the Trust's total return for any period as
a result of the changes in financial reporting of such investments.

(b) There were no changes in the Trust's internal control over financial
reporting that occurred during the fiscal quarter that has materially affected,
or is reasonably likely to materially affect, the Trust's internal control over
financial reporting. However, as discussed above, subsequent to January 31,
2007, the Trust's internal control over financial reporting was revised.


ITEM 3.  EXHIBITS.

(a) A separate certification for each principal executive officer and principal
financial officer of the registrant are attached hereto.
