Dear Stockholder:

We are writing to inform you that the Special Meeting of stockholders of the
above-listed funds has been adjourned until July 25, 2000. The proposal being

("Insured II") will acquire substantially all of the assets of MuniHoldings
Insured Fund III, Inc. and MuniHoldings Insured Fund IV, Inc. solely in
exchange for an equal aggregate value of newly-issued shares of Insured II

Stock of Insured II.

Our records indicate that we have not yet received voting instructions for
