      gross unrealized depreciation is $272,554, resulting in net unrealized
      appreciation of $19,663,277.

(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 their notes to the Dealer
      Trust for redemption at par at each reset date. At January 31, 2007, Trust
      investments with a value of $50,891,590 are held by the Dealer Trust and
      serve as collateral for the $36,260,000 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 November 30,
2006, 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 November 30, 2006, and prior to the
issuance of the Trust'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 November 30,
2006, 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.
