         This Post-Effective Amendment No. 1 to the Registrant's Registration
Statement on Form N-14 (File No. 333-76564) (the "N-14 Registration
Statement") consists of the following:

(1)      Facing Sheet of this Registration Statement.

(2)      Part C of this Registration Statement (including signature page).

Parts A and B are incorporated herein by reference from the Proxy Statement
and Prospectus filed on February 10, 2002 under Rule 497 under the Securities
Act of 1933, as amended (the "Securities Act").

         This Post-Effective Amendment No. 1 to the N-14 Registration
Statement is being filed solely to file a tax opinion of Sidley Austin Brown &
Wood LLP, special tax counsel for the Registrant, as Exhibit 12 to the N-14
Registration Statement. The tax opinion relates to the reorganization of
Merrill Lynch Florida Limited Maturity Municipal Bond Fund of Merrill Lynch
Multi-State Limited Maturity Municipal Series Trust into the Limited Maturity
Portfolio of the Registrant .



                                      2

                                    PART C

                               OTHER INFORMATION

Item 15.   Indemnification.

         Reference is made to Article VI of the Registrant's Articles of
Incorporation, Article VI of the Registrant's By-Laws, Section 2-418 of the
Maryland General Corporation Law and Section 9 of the Distribution Agreement.

         Insofar as the conditional advancing of indemnification moneys for
actions based on the Investment Company Act of 1940, as amended (the
"Investment Company Act"), may be concerned, Article VI of the Registrant's
By-Laws provides that such payments will be made only on the following
conditions: (i) advances may be made only on receipt of a written affirmation
of such person's good faith belief that the standard of conduct necessary for
indemnification has been met and a written undertaking to repay any such
advance if it is ultimately determined that the standard of conduct has not
been met; and (ii) (a) such promise must be secured by a security for the
undertaking in form and amount acceptable to the Registrant, (b) the
Registrant is insured against losses arising by receipt by the advance, or (c)
a majority of a quorum of the Registrant's disinterested non-party Directors,
or an independent legal counsel in a written opinion, shall determine, based
upon a review of readily available facts, that at the time the advance is
proposed to be made, there is reason to believe that the person seeking
indemnification will ultimately be found to be entitled to indemnification.

         In Section 9 of the Distribution Agreement relating to the securities
being offered hereby, the Registrant agrees to indemnify the FAM Distributors,
Inc (the "Distributor") and each person, if any, who controls the Distributor
within the meaning of the Securities Act, against certain types of civil
liabilities arising in connection with the Registration Statement or
Prospectus and Statement of Additional Information.

         Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to Directors, officers and controlling persons
of the Registrant and the principal underwriter pursuant to the foregoing
provisions or otherwise, the Registrant has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a Director, officer, or controlling person of the Registrant and the
principal underwriter in connection with the successful defense of any action,
suit or proceeding) is asserted by such Director, officer or controlling
person or the principal underwriter in connection with the shares being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
