of the discount, the liquidity of the Acquiring Fund’s portfolio, the impact of any action that might be taken on the Acquiring

the Merger SAI under “Repurchase of Common Shares; Conversion to Open-End Fund” for a further discussion of possible
action to reduce or eliminate such discount to net asset value.

AMTP Share payable on any dividend payment date will equal the sum of dividends accumulated but not yet paid for each rate period
during the relevant monthly dividend period. The dividend rate applicable to any rate period (which typically consists of seven
days) is an index rate based on the SIFMA Municipal Swap Index plus an applicable spread. The applicable spread is subject to adjustment
in certain circumstances, including a change in the credit rating assigned to the outstanding AMTP Shares. In no circumstances
may the dividend rate exceed 15% per annum with respect to any rate period.
