     This Post-Effective Amendment No. 1 to the Registrant's Registration
Statement on Form N-14 (File No. 333-76504) (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 Joint Proxy
Statement and Prospectus filed on February 12, 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
Connecticut Municipal Bond Fund, Merrill Lynch Maryland Municipal Bond Fund,
Merrill Lynch Minnesota Municipal Bond Fund, and Merrill Lynch Texas Municipal
Bond Fund, each a series of Merrill Lynch Multi-State Municipal Series Trust
into the National Portfolio of the Registrant.

                                    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.
