                                ELIGIBLE ASSETS

On the Date of Original Issue and at all times thereafter that the VMTP
Preferred Shares are Outstanding:

1. "Eligible Assets" are defined to consist only of assets that conform to the
   following requirements as of the time of investment:

    A. Debt obligations. The following debt obligations which are not in
       payment default at the time of investment:

       i. "Municipal securities," defined as obligations of a State, the
          District of Columbia, a U.S. territory, or a political subdivision
          thereof and including general obligations, limited obligation bonds,
          revenue bonds, and obligations that satisfy the requirements of
          section 142(b)(1) of the Internal Revenue Code of 1986 issued by or
          on behalf of any State, the District of Columbia, any U.S. territory
          or any political subdivision thereof, including any municipal
          corporate instrumentality of 1 or more States, or any public agency
          or authority of any State, the District of Columbia, any U.S.
          territory or any political subdivision thereof. The purchase of any
          municipal security will be based upon the Investment Adviser's
          assessment of an asset's relative value in terms of current yield,
          price, credit quality, and future prospects; and the Investment
          Adviser will monitor the creditworthiness of the Trust's portfolio
          investments and analyze economic, political and demographic trends
          affecting the markets for such assets.

       ii.Debt obligations of the United States.

      iii.Debt obligations issued, insured, or guaranteed by a department or an
          agency of the U.S. Government, if the obligation, insurance, or
          guarantee commits the full faith and credit of the United States for
          the repayment of the obligation.

       iv.Debt obligations of the Washington Metropolitan Area Transit
          Authority guaranteed by the Secretary of Transportation under
          Section 9 of the National Capital Transportation Act of 1969.

       v. Debt obligations of the Federal Home Loan Banks.

       vi.Debt obligations, participations or other instruments of or issued by
          the Federal National Mortgage Association or the Government National
          Mortgage Association.

<PAGE>

      vii.Debt obligations which are or ever have been sold by the Federal Home
          Loan Mortgage Corporation pursuant to sections 305 or 306 of the
          Federal Home Loan Mortgage Corporation Act.

     viii.Debt obligations of any agency named in 12 U.S.C. (S) 24(Seventh) as
          eligible to issue obligations that a national bank may underwrite,
          deal in, purchase and sell for the bank's own account, including
          qualified Canadian government obligations.

       ix.Debt obligations of issuers other than those specified in (i) through
          (viii) above that are rated in one of the three highest rating
          categories by two or more NRSROs, or by one NRSRO if the security has
          been rated by only one NRSRO, and which have been determined by the
          Trust, based on the Trust's internal credit due diligence, to be
          securities where the issuer has adequate capacity to meet financial
          commitments under the security for the projected life of the security
          such that the lack of default on the security such that the risk of
          default on the security is low, and the full and timely repayment of
          principal and interest is expected, and that are "marketable". For
          these purposes, an obligation is "marketable" if:

          .   it is registered under the Securities Act;

          .   it is offered and sold pursuant to Securities and Exchange
              Commission Rule 144A; 17 CFR 230.144A; or

          .   it can be sold with reasonable promptness at a price that
              corresponds reasonably to its fair value.

       x. Certificates or other securities evidencing ownership interests in a
          municipal bond trust structure (generally referred to as a tender
          option bond structure) that invests in (a) debt obligations of the
          types described in (i) above or (b) depository receipts reflecting
          ownership interests in accounts holding debt obligations of the types
          described in (i) above.

An asset shall not fail to qualify as an Eligible Asset solely by virtue of the
fact that:

          .   it provides for repayment of principal and interest in any form
              including fixed and floating rate, zero interest, capital
              appreciation, discount, leases, and payment in kind; or

          .   it is for long-term or short-term financing purposes.

    B. Derivatives

       i. Interest rate derivatives; or

       ii.Swaps, credit default swaps, futures, forwards, structured notes,

    C. Other Assets

       i. (A) Shares of other investment companies registered under Section 8
          of the Investment Company Act of 1940 (open- or closed-end funds and
          ETFs) the assets of which consist entirely of Eligible Assets based
          on the Investment Adviser's assessment of the assets of each such
          investment company taking into account the investment company's most
          recent publicly available schedule of investments and publicly
          disclosed investment policies.

          (B) Notwithstanding Paragraph C.i.(A) above, the Trust shall be
          permitted, subject to Applicable Law, to invest up to five percent
          (5%) of the Trust's Managed Assets as of the time of investment in
          securities issued by a money-market fund (each, an "Eligible
          Money-Market Fund") that is (a) registered under the Investment
          Company Act of 1940, and (b) affiliated with the Investment Adviser;
          provided that if the Investment Advisor represents that the Eligible
          Money-Market Fund meets the requirements of Paragraph C.i.(A) above,
          the amount of such Managed Assets invested in any such Eligible
          Money-Market Fund meeting the requirements of Paragraph C.i.(A) above
          shall be excluded from the foregoing five percent (5%) limitation.

       ii.Cash.

      iii.Repurchase agreements on assets described in A above.

       iv.Taxable fixed-income securities issued by an issuer described in
          Paragraph 1(A) (a "Permitted Issuer") that are not in default at the
          time of acquisition, acquired for the purpose of influencing control
          over such Permitted Issuer or creditor group of municipal bonds of
          such Permitted Issuer (a) the Trust already owns and (b) which have
          deteriorated or are expected shortly to deteriorate, with the
          expectation that such investment should enable the Trust to better
          maximize the value of its existing investment in such issuer,
          provided that the taxable fixed-income securities of such issuer so
          acquired do not constitute more than 0.5% of the Trust's Managed
          Assets as of the time of investment.
