##   Floating rate note obligations related to securities held. The interest
     rates shown reflect the rates in effect at July 31, 2007.

(a)  The Trust invests in Morgan Stanley Institutional Liquidity Tax-Exempt
     Portfolio - Institutional Class, an open end investment management company
     managed by the Investment Adviser. Investment advisory fees paid by the
     Trust are reduced by an amount equal to the advisory and administrative
     service fees paid by Morgan Stanley Institutional Liquidity Tax-Exempt
     Portfolio - Institutional Class with respect to assets invested by the
     Trust in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -
     Institutional Class. Income distributions earned by the Trust totaled
     $42,044 for the period ended July 31, 2007.

(b)  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 Trusts
     have interest rates that reset weekly and the floating rate note holders
     have the option to tender their notes to the Dealer Trusts for redemption
     at par at each reset date. At July 31, 2007, Trust investments with a value
     of $65,404,270 are held by the Dealer Trusts and serve as collateral for
     the $48,260,000 in floating rate note obligations outstanding at that date.
     Contractual maturities of the floating rate note obligations and interest
     rates in effect at July 31, 2007 are presented in the "Portfolio of
     Investments".

(c)  Securities have been designated as collateral in an amount equal to
     $14,026,909 in connection with open futures contracts and an open swap
     contract.

(d)  The aggregate cost for federal income tax purposes is $374,352,041. The
     aggregate gross unrealized appreciation is $15,244,394 and the aggregate
     gross unrealized depreciation is $2,038,001, resulting in net unrealized
     appreciation of $13,206,393.
