NR -- NOT RATED






          
      +      Bank Loans rated below Baa by Moody's Investor Service, Inc. or BBB by Standard & Poor's
             Group are considered to be below investment grade.

             Industry percentages are calculated as a percentage of net assets
             applicable to common shares.

     (a)     This Senior Loan interest is non-income producing.

     (b)     A portion of this security is segregated in connection with unfunded loan commitments.

     (c)     This borrower has filed for protection in federal bankruptcy court.

     (d)     Affiliated company.

     (e)     Non-income producing security as this stock or warrant currently does not declare dividends.

     (f)     Restricted Security. Securities were acquired through the
             restructuring of senior loans. These securities are restricted as
             they are not allowed to be deposited via the Depository Trust
             Company. If at a later point in time, the company wishes to
             register, the issuer will bear the costs associated with
             registration. The aggregate value of restricted securities
             represents 0.03% of the net assets applicable to common shares of
             the Trust.

     (g)     Payment-in-kind security.

     (h)     Variable rate security.  Interest rate shown is that in effect at April 30, 2006.

     (i)     This borrower is currently in liquidation.

     (j)     The borrower is in the process of restructuring or amending the terms of this loan.

     (k)     Subsequent to April 30, 2006, this borrower has filed for protection in federal bankruptcy court.

          *  Senior Loans in the Trust's portfolio generally are subject to
             mandatory and/or optional prepayment. Because of these mandatory
             prepayment conditions and because there may be significant economic
             incentives for a Borrower to prepay, prepayments of Senior Loans in
             the Trust's portfolio may occur. As a result, the actual remaining
             maturity of Senior Loans held in the Trust's portfolio may be
             substantially less than the stated maturities shown. Although the
             Trust is unable to accurately estimate the actual remaining maturity
             of individual Senior Loans, the Trust estimates that the actual
             average maturity of the Senior Loans held in its portfolio will be
             approximately 18-24 months.

         **  Senior Loans in which the Trust invests generally pay interest at
             rates which are periodically redetermined by reference to a base
             lending rate plus a premium. These base lending rates are generally
             (i) the lending rate offered by one or more








          
             major European banks,  such as the London  Inter-Bank  Offered Rate
             ("LIBOR"),  (ii) the prime rate offered by one or more major United
             States  banks and (iii) the  certificate  of deposit  rate.  Senior
             Loans are  generally  considered to be restricted in that the Trust
             ordinarily is contractually  obligated to receive approval from the
             Agent Bank and/or  Borrower  prior to the  disposition  of a Senior
             Loan.
