                                                                     APPENDIX A

                                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 Corporation'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 Corporation, based on the Corporation'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

<PAGE>

       ii.   Swaps, credit default swaps, futures, forwards, structured notes,
             options and swaptions related to Eligible Assets or on an index
             related to Eligible Assets.

    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 Corporation already owns
             and (b) which have deteriorated or are expected shortly to
             deteriorate, with the expectation that such investment should
             enable the Corporation 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 Corporation's Managed Assets as
             of the time of investment.

2. At any time that VMTP Preferred Shares are outstanding, for any investment
   company the securities of which are held by the Corporation, the Corporation
   will provide or make available the following information to the Holders
   within 10 days after the public quarterly release of such information and on
   the Date of Original Issue (for the reporting period having ended most
   recently prior to the closing):

             number of shares owned, as of the end of the prior quarter, and
             the percentage of the investment company's equity represented by
             the Corporation's investment, as of the end of the prior quarter;

       ii.   other than in the case of an investment in an Eligible
             Money-Market Fund, a representation that each such investment
             company invests solely in "Eligible Assets," which representation
             may be based upon the affirmative representation of the underlying
             investment company's investment adviser; and

       iii.  other than in the case of an investment in an Eligible
             Money-Market Fund, the information contained in the most recently
             released financial statements of each such underlying investment
             company relating to the portfolio holdings of each such investment
             company.
