Dear Stockholders:

   The Board of Directors (the "Directors") of ACM Municipal Securities Income
Fund, Inc. ("ACM Municipal Securities") is pleased to invite you to a Special
Meeting of Stockholders of ACM Municipal Securities (the "Meeting") to be held
on Thursday, February 22, 2007. At this Meeting, we are asking you to approve
the acquisition of the assets and the assumption of the liabilities of ACM
Municipal Securities by Alliance National Municipal Income Fund, Inc.
("Alliance National Municipal") and the dissolution of ACM Municipal
Securities. The proposed acquisition is described in more detail in the
attached Prospectus/Proxy Statement.

   Alliance National Municipal is larger and has somewhat broader investment
policies than ACM Municipal Securities. We anticipate that the proposed
acquisition will result in benefits to the stockholders of ACM Municipal
Securities as are more fully discussed in the Prospectus/Proxy Statement.

   The Directors of ACM Municipal Securities have given careful consideration
to the proposed acquisition and have concluded that the acquisition is in the
best interests of ACM Municipal Securities and its stockholders. The Directors
of ACM Municipal Securities unanimously recommend that you vote "for" the
proposed acquisition of ACM Municipal Securities by Alliance National Municipal.

   If the acquisition of ACM Municipal Securities by Alliance National
Municipal is approved, (i) each holder of ACM Municipal Securities common stock
will receive shares of Alliance National Municipal common stock having an
aggregate net asset value ("NAV") equal to the aggregate NAV of the
stockholder's shares in ACM Municipal Securities and (ii) each holder of a
class of ACM Municipal Securities preferred stock will receive shares of a
similar class of Alliance National Municipal preferred stock having the same
aggregate liquidation preference and value. ACM Municipal Securities would then
cease operations. You will not be assessed any sales charges or other
stockholder fees in connection with the proposed acquisition.

   We welcome your attendance at the Meeting. If you are unable to attend, we
encourage you to authorize proxies to cast your votes. The Altman Group, Inc.
(the "Proxy Solicitor"), a proxy solicitation firm, has been selected to assist
in the proxy solicitation process. If we have not received your proxy as the
date of the Meeting approaches, you may receive a telephone call from the Proxy
Solicitor to remind you to submit your proxy. No matter how many shares you
own, your vote is important.

Sincerely,

Marc O. Mayer
President

                             QUESTIONS AND ANSWERS

The following questions and answers provide an overview of key features of the
proposed acquisition and the information contained in this Prospectus/Proxy
Statement. Please review the full Prospectus/Proxy Statement before casting
your vote.

1. What is this document and why did we send it to you?

This is a combined Prospectus/Proxy Statement that provides you with
information about the acquisition (the "Acquisition") of the assets and
assumption of the liabilities of ACM Municipal Securities Income Fund, Inc.
("ACM Municipal Securities") by Alliance National Municipal Income Fund, Inc.
("Alliance National Municipal") and the subsequent dissolution of ACM Municipal
Securities (ACM Municipal Securities and Alliance National Municipal are each a
"Fund" and collectively, the "Funds"). This document also solicits your vote on
the Acquisition by requesting that you approve the Agreement and Plan of
Acquisition and Liquidation dated as of November 20, 2006 (the "Plan"), among
ACM Municipal Securities, Alliance National Municipal and AllianceBernstein
L.P. (the "Adviser").

On November 20, 2006, the Directors approved and declared advisable the
Acquisition of ACM Municipal Securities by Alliance National Municipal and the
subsequent dissolution of ACM Municipal Securities and directed that the
Acquisition and dissolution be submitted to stockholders of ACM Municipal
Securities for approval at a Special Meeting of Stockholders to be held on
February 22, 2007, at 11:00 a.m., Eastern Time (the "Meeting"). You are
receiving this Prospectus/Proxy Statement because you own shares of ACM
Municipal Securities. Each stockholder of record of ACM Municipal Securities as
of the close of business on the record date has the right under applicable
legal and regulatory requirements to vote on the Acquisition and dissolution.
The Acquisition will not occur unless it is approved by ACM Municipal
Securities stockholders. This Prospectus/Proxy Statement contains the
information you should know before voting on the proposed Acquisition.

The Board of Directors of Alliance National Municipal also approved holding a
special meeting of the stockholders of their Fund to seek stockholder approval
of the issuance of shares of Alliance National Municipal common stock to be
issued in connection with the Acquisition. The vote is required under rules of
the New York Stock Exchange ("NYSE") and will be solicited by a separate proxy
statement. If the stockholders of Alliance National Municipal do not approve
the issuance of shares of Alliance National Municipal common stock, the
Acquisition will not occur even if ACM Municipal Securities stockholders
approve the Acquisition.

You may contact a Fund at 1-800-221-5672 or write to a Fund at 1345 Avenue of
the Americas, New York, NY 10105.

2. Who is eligible to vote on the Acquisition?

Stockholders of record at the close of business on December 15, 2006 (the
"Record Date") are entitled to notice of and to vote at the Meeting or any
adjournment or postponement of the Meeting. If you owned common or preferred
stock of ACM Municipal Securities on the Record Date, you have the right to
vote even if you later sold your shares.

Each share of common and preferred stock is entitled to one vote. Common and
preferred stockholders will vote together on the Acquisition. A separate vote
of the preferred stockholders voting as a class is also required to approve the
Acquisition. Shares represented by properly executed proxies, unless revoked
before or at the Meeting will be voted according to stockholders' instructions.
If you sign and return a proxy card but do not fill in a vote, your shares will
be voted "FOR" the Acquisition. If any other business properly comes before the
Meeting, your shares will be voted at the discretion of the persons named as
proxies.

3. How will the Acquisition work?

The Plan provides for: (i) the transfer of all of the assets of ACM Municipal
Securities to Alliance National Municipal, (ii) the assumption by Alliance
National Municipal of all of the liabilities of ACM Municipal Securities,
(iii) the liquidating distribution to ACM Municipal Securities common
stockholders of shares of Alliance

                                      4



National Municipal common stock equal in aggregate net asset value ("NAV") to
their former ACM Municipal Securities shares of common stock and to preferred
stockholders a similar class of Alliance National Municipal preferred stock
having the same aggregate liquidation preference and value, and (iv) the
dissolution of ACM Municipal Securities.

As a result of the Acquisition, stockholders of ACM Municipal Securities will
no longer hold shares of ACM Municipal Securities, and instead, will become
stockholders of Alliance National Municipal having, with respect to common
stockholders, the same aggregate NAV as the shares of ACM Municipal Securities
common stock that they held immediately before the Acquisition and, with
respect to the preferred stockholders, the same aggregate liquidation
preference and value they held immediately before the Acquisition. Please note
that ACM Municipal Securities common stockholders who do not participate in ACM
Municipal Securities' Dividend Reinvestment and Cash Purchase Plan will receive
cash in lieu of fractional shares.

You will not be assessed any sales charges or other stockholder fees in
connection with the proposed Acquisition. The Acquisition will not occur unless
the stockholders of ACM Municipal Securities approve the Acquisition and
stockholders of Alliance National Municipal approve the issuance of shares of
Alliance National Municipal to be issued in connection with the Acquisition.

4. Why is the Acquisition being proposed?

Based on the recommendation of the Adviser, the Board of Directors of ACM
Municipal Securities (the "Board") concluded that participation by ACM
Municipal Securities in the proposed Acquisition is in the best interests of
ACM Municipal Securities and its stockholders. The Board also concluded that
the proposed Acquisition would not dilute stockholders' interests. In reaching
this conclusion, the Board considered, among other things, the Funds'
investment objectives and investment policies, the expense benefits for ACM
Municipal Securities common stockholders expected to result from the
Acquisition, the investment performance and trading history of the Funds'
common stock, the costs of the Acquisition, and the tax-free nature of the
Acquisition. It is not anticipated that the Acquisition will directly benefit
ACM Municipal Securities preferred stockholders; however, the Acquisition will
not adversely affect the preferred stockholders of ACM Municipal Securities.

5. When will the Acquisition Take Place?

If the stockholders of ACM Municipal Securities approve the Acquisition, then
the Acquisition is expected to occur in the second quarter of 2007.

6. Where May I Find Additional Information Regarding the Funds?

Additional Information ("SAI") dated January 8, 2007 that has been filed with

                                   PROPOSAL:
       APPROVAL OF AN AGREEMENT AND PLAN OF ACQUISITION AND LIQUIDATION
                      AMONG ALLIANCE NATIONAL MUNICIPAL,
                   ACM MUNICIPAL SECURITIES AND THE ADVISER

I. Introduction

   On November 20, 2006, the Board of Directors of ACM Municipal Securities
declared advisable and voted to approve the Plan and the transactions
contemplated thereby, subject to the approval of ACM Municipal Securities
stockholders. The Plan provides for: (i) the transfer of all of the assets of
ACM Municipal Securities to Alliance National Municipal, (ii) and the
assumption by Alliance National Municipal of all of the liabilities of ACM
Municipal Securities, (iii) the liquidating distribution to ACM Municipal
Securities common stockholders of shares of Alliance National Municipal common
stock equal in aggregate NAV to their former ACM Municipal Securities shares of
common stock and to preferred stockholders a similar class of Alliance National
Municipal preferred stock having the same aggregate liquidation preference and
value, and (iv) the dissolution of ACM Municipal Securities.

   Each holder of ACM Municipal Securities common stock will receive the number
of full shares of Alliance National Municipal common stock, plus fractional
shares for stockholders that participate in a Dividend Reinvestment and Cash
Purchase Plan ("DRIP") and cash in lieu of any fractional shares for non-DRIP
participating stockholders, having an aggregate NAV that is equal to the
aggregate NAV of the stockholder's shares of ACM Municipal Securities common
stock. Holders of ACM Municipal Securities common stock will recognize no gain
or loss, except with respect to any cash received in lieu of fractional
Alliance National Municipal shares by non-DRIP stockholders. If approved by
stockholders of ACM Municipal Securities, the Acquisition is expected to occur
in the second quarter of 2007.

   Each holder of ACM Municipal Securities Preferred Shares Series A, Preferred
Shares Series B, and Preferred Shares C will receive respectively, Alliance
National Municipal Preferred Shares Series W, Preferred Series M and Preferred
Shares Series TH having, in each case, an aggregate liquidation preference and
value equal to the aggregate liquidation preference and value attributable to
the respective class of ACM Municipal Securities preferred stock.

   An exchange of ACM Municipal Securities common stock for Alliance National
Municipal common stock at NAV may result in ACM Municipal Securities
stockholders' receiving Alliance National Municipal shares with an aggregate
market value on the date of exchange that is higher or lower than the market
value of their shares immediately prior to the exchange. The reason for this
difference is that the market price for shares of the Funds in relation to
their NAVs may be different, i.e., a Fund's shares may trade at different
discounts or premiums to its NAV.

   The stockholders of ACM Municipal Securities must approve the Acquisition
for it to occur. The holders of ACM Municipal Securities common stock and the
holders of ACM Municipal Securities preferred stock will vote together on the
Acquisition. In addition, holders of ACM Municipal Securities preferred stock
will vote separately as a class on the Acquisition. Approval of the Acquisition
requires: (i) the affirmative vote by ACM Municipal Securities common stock and
preferred stockholders entitled to cast a majority of the votes entitled to be
cast on the matter, voting together as a single class and (ii) with respect to
ACM Municipal Securities preferred stockholders, voting as a separate class,
the affirmative vote of the holders of a "majority of the outstanding voting
securities" as defined in the Investment Company Act of 1940 Act (the "1940
Act"), which means the lesser of (i) 67% or more of such shares present or
represented by proxy, if the holders of more than 50% of the outstanding
preferred stock are present or represented by proxy, or (ii) more than 50% of
the outstanding shares of preferred stock of ACM Municipal Securities. Although
stockholders of Alliance National Municipal are not being asked to approve the
Acquisition, they will be asked at a separate stockholder meeting to approve
the issuance of shares of common stock of Alliance National Municipal in
connection with the Acquisition. If stockholders of Alliance National Municipal
do not approve the issuance of the shares of its common stock in connection
with the Acquisition, the Acquisition will not occur even if ACM Municipal
Securities common and preferred stockholders approve the Acquisition.

                                      7



   A quorum for the transaction of business by common stockholders and
preferred stockholders of ACM Municipal Securities will consist of the presence
in person or by proxy of the holders of a majority of the shares of the Fund
entitled to vote at the Meeting. In addition, with respect to the separate vote
by preferred stockholders, a quorum will consist of the presence in person or
by proxy of the holders of a majority of the shares of the preferred stock
entitled to vote at the Meeting.

   The Board of Directors of ACM Municipal Securities concluded that ACM
Municipal Securities' participation in the proposed Acquisition is in the best
interests of ACM Municipal Securities and its stockholders. The Board also
concluded that the proposed Acquisition would not dilute stockholders'
interests. In reaching this conclusion, the Board considered, among other
things, the Funds' investment objectives and investment policies, the
investment performance and trading history of the Funds' common stock, the
expense benefits for ACM Municipal Securities common stockholders expected to
result from the Acquisition, the cost thereof, and the tax-free nature of the
Acquisition. It is not anticipated that the Acquisition will directly benefit
ACM Municipal Securities preferred stockholders; however, the Acquisition will
not adversely affect the preferred stockholders of ACM Municipal Securities.
For a more complete discussion of the factors considered by the Board in
approving the Acquisition, see "Reasons for the Acquisition" in Information
About the Proposed Transaction.

                                    SUMMARY

   The following summary highlights differences between the Funds. This summary
is not complete and does not contain all of the information that you should
consider before voting on the Acquisition. For more complete information,
please read this entire document. Note that certain information is presented as
of April 30, 2006. At the November 20, 2006, Special Board Meeting of the Board
of Directors of ACM Municipal Securities referred to below (the "November 20
Meeting"), the Adviser represented to the Board that, if the information was
updated, it would not differ in any material respect.

Comparison of Investment Advisory Fees

   The current management fees of the Funds are shown in the table below. As
indicated in the table, we expect that the Combined Fund would have a lower
management fee after the Acquisition than the current management fee of ACM
Municipal Securities.



                                Management Fee         Management Fee
                                Before Waiver           After Waiver
                               --------------         --------------
                                                
   ACM Municipal Securities         0.50%                  0.50%
   Alliance National Municipal      0.65%                  0.40%
   Combined Fund                    0.65% (pro forma)      0.40% (pro forma)


   Alliance National Municipal's contractual management fee is 0.65% of its
average daily net assets. The management fee is calculated on the basis of net
assets (including assets attributable to preferred stock) accrued daily and
reflected in the net asset value of the common stock. The Adviser has
voluntarily agreed to waive a portion of Alliance National Municipal's
management fee or reimburse the Fund for expenses in the amount of 0.25% of the
Fund's average daily net assets until January 28, 2007 with the waiver
decreasing by 0.05% for each one year period commencing January 28 thereafter
with the full fee being payable commencing January 28, 2011 and beyond.
However, on November 20, 2006, the Adviser agreed, at the request of the
Directors, to place a cap on the amounts payable under the Advisory Agreement
of 0.55% of Alliance National Municipal's average daily net assets. The Adviser
has also agreed to request that the Board approve a new investment advisory
contract between the Adviser and Alliance National Municipal that would make
the maximum fee of 0.55% permanent. Even when the management fee increases to
its maximum amount of 0.55% in January 2009, ACM Municipal Securities
stockholders would benefit, as discussed below, from overall decreased expenses
as a result of the Acquisition.

Fee Table and Comparison of Total Expenses Ratios

                                   FEE TABLE

   The purpose of the tables below is to assist you in understanding the
various costs and expenses that a stockholder bears directly and indirectly
from an investment in the Funds. The tables allow you to compare the sales
charges, expenses of each Fund and the estimates for the combined Fund in its
first year following the Acquisition (shown as a percentage of net assets,
excluding assets attributable to preferred stock).

(a)There are no charges with respect to stock issued directly by a Fund to
   satisfy the dividend reinvestment requirements. However, each participant
   will pay a pro-rata share of brokerage commissions incurred with respect to
   a Fund's dividend reinvestment plan agent's open market purchases of stock.
   In each case, the cost per share of stock purchased for each stockholder's
   account will be the average cost, including brokerage commissions, of any
   stock purchased in the open market plus the cost of any stock issued by a
   Fund.
(b)The Adviser has voluntarily agreed to waive a portion of its fees or
   reimburse the Fund for expenses in the amount of 0.25% of the Fund's average
   daily net assets (including assets attributable to the common and preferred
   stock) for the first 5 full years of the Fund's operations (the Fund is in
   its 5th year of operation), with 0.20% of the Fund's average daily net
   assets attributable to common and preferred stock in year 6, 0.15% in year
   7, 0.10% in year 8, and 0.05% in year 9. The Adviser has agreed to place a
   cap on the advisory fee rate of 0.55% and to seek approval of the Board of a
   new investment advisory contract with a maximum fee rate of 0.55%. For the
   year ended October 31, 2005, the amount of such fees waived was $1,284,310.
(c)Based on estimated expenses.
(d)As noted above, the Adviser has voluntarily waived a portion of its fees or
   reimbursed the Fund for expenses so that the current advisory fee for
   Alliance National Municipal is 0.40%. Assuming this waiver and the maximum
   fee of 0.65% based on common average daily net assets agreed to by the
   Adviser, the expenses would be:

EXAMPLE

   You would pay the following on a $1,000 investment assuming a 5% annual
return. The Example assumes the reinvestment of all dividends and distributions
at net asset value and reflects all recurring and nonrecurring fees.

                After 10 Years   $166       $189       $147

** The Adviser has agreed to place a cap on the advisory fee rate of 0.55%
   based on common and preferred average daily net assets. The pro forma
   expenses give effect to the new cap on the advisory fee rate and are based
   on net assets attributable to common stock only.

   The projected post-Acquisition pro forma Annual Fund Expenses and Example
presented above are based upon numerous material assumptions, including that
(1) the current contractual agreements will remain in place and (2) certain
fixed costs involved in operating ACM Municipal Securities are eliminated.
Although these projections represent good faith estimates, there can be no
assurance that any particular level of expenses or expense savings will be
achieved, because expenses depend on a variety of factors, many of which are
beyond the control of Alliance National Municipal or the Adviser. Consequently,
the Example should not be considered a representation of future expenses.
Actual expenses may be greater or less than those shown.

Comparison of Total Operating Expenses

   This discussion provides an explanation of the information regarding
expenses included in the Fee Table above. ACM Municipal Securities, which is
approximately one-half the size of Alliance National Municipal, has higher
total operating expenses than Alliance National Municipal (before and after
waiver). The Acquisition would, as shown below, result in a sizeable reduction
in operating expenses for former common stockholders of ACM Municipal
Securities. ACM Municipal Securities has a 0.15% administration fee (of which
the Adviser in its capacity as the Fund's Administrator is currently waiving
0.10%). Alliance National Municipal does not have a separate administration fee
and although its advisory contract provides for reimbursement for the costs of
providing certain administrative services, the Adviser has not sought such
reimbursement and has no current intention of doing so.

   Total expenses on a net and gross basis (shown as a percentage of net assets
including assets attributable to common and preferred stock) for the period
November 1, 2005 through April 30, 2006, annualized for the Funds were:



                                  Total Annual          Total Annual
                                  Expense Ratio        Expense Ratio
                                  After Waivers        Before Waivers
                                -------------         --------------
                                                
    ACM Municipal Securities        0.84%                  0.94%
    Alliance National Municipal     0.60%                  0.85%
    Combined Fund                   0.59% (pro forma)      0.84% (pro forma)


   As the table indicates, after giving effect to waivers, the estimated
expenses after the Acquisition are 0.25% lower than ACM Municipal Securities'
current expenses. In addition, as the table indicates, on a "before waivers"
basis, ACM Municipal Securities stockholders would benefit even if the maximum
management fee (before the new capped fees) of Alliance National Municipal was
applicable.

                                      11



   Giving effect to the new advisory fee cap of 0.55%, the gross expense ratio
would be:



                                             Gross Expense
                                                 Ratio
                                           -------------
                                        
               ACM Municipal Securities        0.94%
               Alliance National Municipal     0.75%
               Combined Fund                   0.74% (pro forma)


   As indicated in the table, on a "before waivers" basis ACM Municipal
Securities stockholders would benefit even if the maximum fee of 0.55% were
applicable, because the total gross expense ratio on a pro forma basis would be
0.74%, a reduction of 0.20%.

   If the Fund's expenses were based on a percentage of net assets attributable
to each Fund's common stock (i.e., excluding assets attributable to preferred
stock), total expenses on a net and gross basis for the period November 1, 2005
through April 30, 2006, annualized for the Funds were:



                                    Net Expense         Gross Expense
                                       Ratio                Ratio
                                 -----------          -------------
                                                
     ACM Municipal Securities       1.43%                 1.61%
     Alliance National Municipal    0.98%                 1.38%
     Combined Fund                  0.97% (pro forma)     1.38% (pro forma)


   Giving effect to the new advisory fee cap of 0.55%, the gross expense ratio
would be:



                                             Gross Expense
                                                 Ratio
                                           -------------
                                        
               ACM Municipal Securities        1.61%
               Alliance National Municipal     1.22%
               Combined Fund                   1.21% (pro forma)


   The large difference between the expense ratios of ACM Municipal Securities
and Alliance National Municipal is primarily due to the effect of spreading
fixed expenses over a larger asset base for Alliance National Municipal and the
Combined Fund.

Comparison of Investment Objectives and Policies

   Alliance National Municipal is a fund of significantly larger size and scale
that employs investment strategies similar to ACM Municipal Securities although
Alliance National Municipal has greater investment flexibility than ACM
Municipal Securities. Both Funds primarily invest in municipal securities
exempt from regular federal income tax. The following table shows the Funds'
investment objectives and certain principal investment strategies.

                                                                bonds rated below investment grade.


                                      12



   As the table above shows, the Funds have similar investment strategies of
investing primarily in investment grade municipal securities. Although Alliance
National Municipal has greater flexibility to invest in municipal bonds rated
below investment grade, the constraints imposed by the ratings agencies in
order for Alliance National Municipal to maintain the rating on its preferred
stock significantly limit the extent to which the Fund can use this flexibility.

   When ACM Municipal Securities was first offered, most investors were not
subject to the alternative minimum tax ("AMT"). Over time, however, an
increasing percentage of investors have become subject to the AMT. In response
to that trend, ACM Municipal Securities has decreased the percentage of its
portfolio that is invested in bonds that pay interest that is subject to the
AMT and, currently, approximately 16% of ACM Municipal Securities' assets are
invested in bonds that pay interest that is subject to the AMT. Alliance
National Municipal is a more recently organized Fund that primarily invests in
bonds that pay interest that is not subject to the AMT. However, the Fund may
invest without limit in bonds that pay interest that is subject to the AMT.
Currently, Alliance National Municipal invests approximately 23% of its assets
in bonds that pay interest that is subject to the AMT. A more detailed
comparison of the Funds' existing investment strategies and policies is
provided in Appendix A. You can find additional information on the Funds in the
SAI.

   Both of the Funds use similar preferred stock for leverage. The Adviser
recommended and the Board approved that the Combined Fund maintain the current
level of leverage through the continued use of preferred stock and that the
classes of ACM Municipal Securities preferred stock be exchanged for preferred
stock of Alliance National Municipal having the same aggregate liquidation
preference and value. Specifically, ACM Municipal Securities Preferred Shares
Series A would be exchanged for Alliance National Municipal Preferred
Shares Series W; ACM Municipal Securities Preferred Shares Series B would be
exchanged for Alliance National Municipal Preferred Shares Series M; and ACM
Municipal Securities Preferred Shares Series C would be exchanged for Alliance
National Municipal Preferred Shares Series TH. A discussion of the Funds'
preferred stock is provided in Appendix C.

Principal Risks

   Each Fund is subject to market risk, interest rate risk, credit risk,
leverage risk, and municipal bond market risk. There are no substantial
differences in the principal risks to which the Funds are subject. A
description of each of these and other risks is provided in Appendix B.

Federal Income Tax Consequences

   No gain or loss will be recognized by the ACM Municipal Securities
stockholders except with respect to cash received in lieu of fractional shares
of Alliance National Municipal by non-DRIP stockholders, as a result of the
Acquisition. The aggregate tax basis of the shares of Alliance National
Municipal received by a stockholder of ACM Municipal Securities (including any
fractional shares to which the stockholder may be entitled) will be the same as
the aggregate tax basis of the stockholder's shares of ACM Municipal
Securities. The holding period of the shares of Alliance National Municipal
common stock and preferred stock received by a stockholder of ACM Municipal
Securities (including any fractional shares to which the stockholder may be
entitled) will include the holding period of the shares of ACM Municipal
Securities common stock or preferred stock held by the stockholder, provided
that such shares are held as capital assets by the stockholder of ACM Municipal
Securities at the time of the Acquisition. The holding period and tax basis of
each asset of ACM Municipal Securities in the hands of Alliance National
Municipal as a result of the Acquisition will be the same as the holding period
and tax basis of each such asset in the hands of ACM Municipal Securities prior
to the Acquisition. Any gain or loss realized by a common stockholder of ACM
Municipal Securities upon receipt of cash in lieu of fractional shares of
common stock of Alliance National Municipal by non-DRIP stockholders will be
recognized by the stockholder and measured by the difference between the amount
of cash received and the basis of the fractional share and, provided that the
ACM Municipal Securities shares surrendered constitute capital assets in the
hands of the stockholder, will be capital gain or loss. This tax information is
based on the advice of Seward & Kissel LLP, counsel to the Fund. It is a
condition to the closing of the Acquisition that such advice be confirmed in a
written opinion of counsel. An opinion of counsel is not binding on the
Internal Revenue Service.

                                      13



   ACM Municipal Securities has capital loss carryforwards of approximately
$22.5 million, or $2.02 per share, while Alliance National Municipal has
capital loss carryforwards of approximately $1.5 million or $0.07 per share.
After the Acquisition, the Combined Fund's capital loss carryforwards will be
approximately $24 million, or $0.84 per share. As a result, the amount of loss
carryforwards available to ACM Municipal Securities' stockholders will be
reduced significantly. In addition, the acquisition of ACM Municipal Securities
is likely to trigger the loss limitation provisions of section 382 of the
Internal Revenue Code, the "Code", which would subject the use of the loss
carryforwards to an annual limitation for taxable years after the Acquisition.
This could accelerate potential distributions of net realized capital gains to
the Combined Fund's stockholders. However, it is unclear whether the Combined
Fund would be able to use all of its capital loss carryforwards before they
expire.

Service Providers

   The Funds have the same service providers, which will continue in their
capacity after the Acquisition, with one exception. State Street Bank and Trust
Company serves as the custodian for Alliance National Municipal, and will serve
in that capacity after the Acquisition in lieu of ACM Municipal Securities'
current custodian, The Bank of New York.

Comparison of Stockholder Services

   The stockholder services of each Fund are generally the same. The DRIP,
which is available to the Funds' stockholders, provides automatic reinvestment
of dividends and capital gain distributions in additional shares of a Fund's
common stock. The DRIP also allows stockholders to make optional cash
investments in shares of a Fund's common stock through a plan agent. Assuming
the Acquisition is approved, the DRIP stockholders of ACM Municipal Securities
will automatically be enrolled in the DRIP for Alliance National Municipal. A
more detailed discussion of the DRIP and other stockholder services and
procedures is provided in Appendix C.

Comparison of Business Structures

   Each Fund is organized as a Maryland corporation and is governed by its
Charter, Bylaws and Maryland law. Generally, there are no significant
differences between the Funds in terms of their respective corporate
organizational structure. For more information on the comparison of the
business structure of the Funds, see Appendix C.

                  INFORMATION ABOUT THE PROPOSED TRANSACTION

Introduction

   This Prospectus/Proxy Statement is provided to you to solicit your proxy for
exercise at the Meeting to approve the acquisition of the assets and assumption
of the liabilities of ACM Municipal Securities by Alliance National Municipal
and the liquidation and subsequent dissolution of ACM Municipal Securities. The
Meeting will be held at the offices of the Funds, 1345 Avenue of the Americas,
41/st/ Floor, New York, New York 10105 at 11:00 a.m., Eastern Time, on
February 22, 2007. This Prospectus/Proxy Statement, the accompanying Notice of
a Special Meeting of Stockholders and the enclosed proxy card are being mailed
to stockholders of ACM Municipal Securities on or about January 8, 2007.

Description of the Plan

   As provided in the Plan, Alliance National Municipal will acquire all the
assets and assume all the liabilities of ACM Municipal Securities at the
effective time of the Acquisition (the "Effective Time"). In return, Alliance
National Municipal will issue, and ACM Municipal Securities will distribute to
its holders of common stock, a number of full and fractional shares of Alliance
National Municipal common stock (and cash in lieu of fractional shares for
non-DRIP stockholders), determined by dividing the net value of all the assets
of ACM Municipal Securities (i.e., cash or other assets (including interest
accrued but not yet received) minus all liabilities (including accrued
expenses) and the aggregate liquidation value of the outstanding preferred
stock of ACM Municipal Securities) by the NAV of one share of common stock of
Alliance National Municipal. For this purpose, the Plan provides the times for
and methods of determining the net value of the assets of each Fund. The Plan
provides that stockholders of ACM Municipal Securities common stock will be
credited with shares of Alliance National Municipal (or cash in lieu of
fractional shares for non-DRIP stockholders) corresponding to the aggregate NAV
of the ACM Municipal Securities' shares of common stock that the stockholder
holds of record at the Effective Time. The shares of Alliance National
Municipal Preferred Shares Series M, Preferred Shares Series W and Preferred
Shares Series TH that Alliance National Municipal issues to holders of ACM
Municipal Securities Preferred Shares Series B, Preferred Shares Series A, and
Preferred Shares Series C, respectively, will have an aggregate liquidation
preference and value equal to the aggregate liquidation preference and value of
the outstanding ACM Municipal Securities preferred stock.

   Prior to the transfer of the assets and liabilities of ACM Municipal
Securities to Alliance National Municipal, Alliance National Municipal will
file Articles of Amendment and/or Articles Supplementary to the Fund's Charter
authorizing the issuance of additional shares of Preferred Shares Series M,
Preferred Shares Series W and Preferred Shares Series TH with the State
Department of Assessments and Taxation of Maryland (the "Maryland Department").
Following the distribution of shares of Alliance National Municipal in full
liquidation of ACM Municipal Securities, ACM Municipal Securities will wind up
its affairs, and liquidate and dissolve as soon as is reasonably practicable
after the Acquisition. In the event the Acquisition does not receive the
required stockholder approval, ACM Municipal Securities will continue its
operations and its Directors will consider what future action, if any, is
appropriate.

   The projected expenses of the Acquisition, largely those for legal,
accounting, printing and proxy solicitation expenses, are estimated to total
approximately $372,000 of which $234,000 will be borne by ACM Municipal
Securities and $138,000 will be borne by Alliance National Municipal.

   The Acquisition is expected to occur in the second quarter of 2007. The
Acquisition is conditioned upon approval of the Plan by ACM Municipal
Securities stockholders, the approval of Alliance National Municipal
stockholders of the issuance of shares of Alliance National Municipal common
stock in connection with the Acquisition, and the Funds satisfying the terms of
the Plan. Under applicable legal and regulatory requirements, none of the
holders of ACM Municipal Securities' common stock will be entitled to exercise
objecting stockholders' appraisal rights, i.e., to demand the fair value of
their shares in connection with the Acquisition. Therefore, stockholders will
be bound by the terms of the Acquisition under the Plan. However, any holder of
ACM Municipal Securities common stock may sell shares of common stock on the
NYSE prior to the Acquisition. The

                                      15



shares of ACM Municipal Securities common stock may cease trading on the NYSE
beginning several days prior to the date of the Acquisition. Any cessation of
trading will be accomplished in compliance with NYSE rules, including issuance
of a press release.

   After the Acquisition, shares of ACM Municipal Securities common stock will
be removed from listing on the NYSE. In addition, shares of ACM Municipal
Securities common stock will be withdrawn from registration under the
Securities Exchange Act of 1934 and ACM Municipal Securities will deregister as
an investment company under the Investment Company Act of 1940, as amended (the
"1940 Act") and will dissolve under Maryland law.

   Since the preferred stock of ACM Municipal Securities are not traded
publicly on a national securities exchange, holders of such shares are entitled
to appraisal rights upon the consummation of the Acquisition. The preservation
and exercise of appraisal rights are conditioned on strict adherence to the
applicable provisions of the Maryland General Corporation Law, or MGCL. Each
holder of preferred stock desiring to exercise appraisal rights should refer to
Title 3, Subtitle 2, of the MGCL for a complete statement of their rights and
the steps which must be followed in connection with the exercise of those
rights. The following summary of the rights of objecting stockholders does not
purport to be a complete statement of the procedures to be followed by
preferred stockholders of ACM Municipal Securities desiring to exercise
appraisal rights, a holder of preferred stock of ACM Municipal Securities
desiring to receive payment of the fair value of his or her stock (an
"objecting stockholder") (i) must file with ACM Municipal Securities a written
objection to the Acquisition at or before the Meeting for ACM Municipal
Securities, (ii) must not vote in favor of the Plan (although a vote against
the Plan is not required), and (iii) must make written demand on Alliance
National Municipal for payment of his or her stock, stating the number and
class of shares for which he or she demands payment, within 20 days after the
Maryland Department accepts for filing the Articles of Transfer with respect to
the Acquisition (Alliance National Municipal is required promptly to give
written notice to all objecting stockholders of the date that the Articles of
Transfer are accepted for record). A vote against the Plan will not be
sufficient to satisfy the requirement of a written demand described in (iii).
An objecting stockholder who fails to adhere to this procedure will be bound by
the terms of the Plan. An objecting stockholder ceases to have any rights of a
stockholder except the right to receive fair value for his or her shares and
has no right to receive any dividends or distribution payable to such holders
on a record date after the close of business on the date on which fair value is
to be determined, which, for these purposes, will be the date of the Meeting
for ACM Municipal Securities. A demand for payment of fair market value may not
be withdrawn, except upon the consent of Alliance National Municipal. Within 50
days after the Articles of Transfer have been accepted for filing, an objecting
stockholder who has not received payment for his or her shares may petition a
court located in Baltimore, Maryland for an appraisal to determine the fair
market value of his or her stock.

   Completion of the Acquisition is subject to certain conditions set forth in
the Plan, some of which may be waived by a party to the Plan. The Plan may be
amended in any mutually agreed manner, except that no amendment may be made
subsequent to the Meeting that materially alters the obligations of either
party. The parties to the Plan may terminate the Plan by mutual consent and
either party has the right to unilaterally terminate the Plan under certain
circumstances. Among other circumstances, either party may at any time
terminate the Plan unilaterally upon a determination by the party's Board of
Directors that proceeding with the Plan is not in the best interests of the
Fund or its stockholders.

   A copy of a form of the Plan is attached as Appendix D.

Reasons for the Acquisition

   At the November 20 Meeting, the Adviser recommended that the Board of
Directors approve and recommend to the Fund's stockholders for their approval
the proposed Plan and the Acquisition. The Directors considered the factors
discussed below from the point of view of the interests of the Fund and its
stockholders. After careful consideration, the Board of Directors (including
all of the Directors who are not "interested persons" of the Fund, the Adviser
or its affiliates) determined that the Acquisition would be in the best
interests of the Fund's stockholders and that the interests of existing
stockholders of the Fund would not be diluted as a result of the

                                      16



Acquisition. The Directors unanimously approved the Plan and the Acquisition
and the Directors of ACM Municipal Securities recommended that the stockholders
of ACM Municipal Securities vote in favor of the Acquisition by approving the
Plan.

   The Adviser presented the following information and reasons in favor of the
Acquisition:

  .   ACM Municipal Securities, which was launched in 1993, raised $194.7
      million (including $90 million from preferred stock) in its initial
      public offerings. As of April 30, 2006, ACM Municipal Securities' total
      assets were $213 million, which includes the $90 million attributable to
      preferred stock. Alliance National Municipal, which was launched in 2002,
      raised $486 million (including $195 million from preferred stock) in its
      initial public offerings. As of April 30, 2006, Alliance National
      Municipal's total assets were $508 million, which includes the $195
      million attributable to preferred stock.

  .   The Adviser discussed with the Board that it believes that the
      Acquisition of ACM Municipal Securities, which is a smaller fund with
      higher operating expenses, by its larger counterpart, Alliance National
      Municipal, would benefit ACM Municipal Securities and its stockholders.
      Currently, Alliance National Municipal and ACM Municipal Securities have
      essentially the same investment strategies of investing in investment
      grade municipal securities, although, as discussed herein, Alliance
      National Municipal has greater investment flexibility than ACM Municipal
      Securities.

  .   The Adviser also discussed that ACM Municipal Securities is ten years
      older than Alliance National Municipal so that the period during which
      their performance can be compared is relatively short. While the
      three-year returns for the Funds based on net asset value through
      September 30, 2006 are similar, 7.66% and 7.99%, respectively, Alliance
      National Municipal outperformed ACM Municipal Securities in the past year
      with returns of 6.34% versus 5.93% for ACM Municipal Securities. ACM
      Municipal Securities performed modestly better in 2003 and 2004, while
      Alliance National Municipal outperformed ACM Municipal Securities in 2005
      and through September 30 in 2006. As the Adviser explained, the
      differences in performance for these Funds, which pursue essentially the
      same strategy, are primarily due to the effect of the timing of their
      offerings on the composition of each Fund's portfolio. ACM Municipal
      Securities, being ten years older, had established positions in longer
      duration securities and higher credit spread securities in 2002, when
      Alliance National Municipal was launched. Market conditions in 2003
      provided ACM Municipal Securities with the opportunity to take advantage
      of a stronger market and advantageously reduce its position in higher
      credit spread securities. The Funds' credit profiles are now
      substantially the same and Alliance National Municipal's recent
      outperformance benefited from its lower expenses and shorter duration.

   At the November 20 Meeting, the Directors (with the advice and assistance of
independent counsel) also considered, among other things:

  .   potential stockholder benefits including that (i) the total expenses of
      Alliance National Municipal on a pro forma basis after the Acquisition
      would be significantly lower than the current expenses of ACM Municipal
      Securities and (ii) the potential for ACM Municipal Securities'
      stockholders to benefit from increased earnings of Alliance National
      Municipal after the Acquisition due to the higher earnings of Alliance
      National Municipal;

  .   the current asset levels of ACM Municipal Securities and the combined pro
      forma asset levels of Alliance National Municipal;

  .   the distribution and trading history of the two Funds, including that
      Alliance National Municipal's dividend has consistently exceeded that of
      ACM Municipal Securities, and that the trading price of Alliance National
      Municipal's common stock compared to its net asset value is currently
      somewhat more favorable than that of ACM Municipal Securities (trading
      price information for the two Funds in provided in Appendix F);

  .   the advisory and administration fee arrangements of the two Funds,
      including that Alliance National Municipal's advisory fee rate, after
      waiver, is currently lower than that of ACM Municipal Securities

                                      17



     and is, after waiver, 0.40%, but will increase by 0.05% per year
      commencing January 28, 2007 to a maximum of 0.65% in 2011 and beyond but
      that the cap on the advisory fee recently agreed to by the Adviser upon
      the request of the Board will result in a maximum fee of 0.55%, and that
      the Adviser has agreed to seek approval of a new investment advisory
      contract by the Directors that would make the maximum fee rate of 0.55%
      contractual;

  .   the amount and type of preferred stock used as leverage by the two Funds;

  .   the investment objectives and principal investment strategies of the
      Funds; and

  .   the portfolio management team of Alliance National Municipal, which is
      the same as the portfolio management team of ACM Municipal Securities,
      would continue to manage Alliance National Municipal after the
      Acquisition.

   The Directors also considered, among other things:

  .   the historical and pro forma tax attributes of ACM Municipal Securities,
      including that ACM Municipal Securities has realized capital gains and
      sizable capital loss carryforwards and that Alliance National Municipal
      has a lower amount of capital loss carryforwards, which will
      significantly reduce the amount of loss carryforwards available to ACM
      Municipal Securities' stockholders after the Acquisition and trigger the
      loss limitations provisions of the Internal Revenue Code, although it is
      uncertain whether the Combined Fund would be able to use these capital
      loss carryforwards before they expire;

  .   the form of the Plan and the terms and conditions of the Acquisition;

  .   the effect of the Acquisition on the advisory fees of the Funds;

  .   whether the Acquisition would result in the dilution of stockholders'
      interests;

  .   the number of stockholder accounts and average account sizes of the Funds;

  .   changes in service providers that would result from the Acquisition;

  .   the benefits of the Acquisition to persons other than ACM Municipal
      Securities and its stockholders, including the Adviser in particular,
      which would benefit from the elimination of monitoring and administering
      ACM Municipal Securities, a relatively small fund, that is substantially
      duplicative of its larger counterpart, Alliance National Municipal;

  .   that Alliance National Municipal will assume all the liabilities of ACM
      Municipal Securities;

  .   the expected federal income tax consequences of the Acquisition;

  .   whether the Acquisition would be preferable to acquisition by potential
      acquirers other than Alliance National Municipal including funds that are
      not sponsored by the Adviser;

  .   that the costs of the Acquisition will be borne by ACM Municipal
      Securities and Alliance National Municipal;

  .   the tender offer/repurchase policies of the two Funds, which differ
      somewhat; and

  .   that the Adviser has agreed to indemnify Alliance National Municipal for
      a three-year period against any undisclosed or other liability of ACM
      Municipal Securities and to reimburse Alliance National Municipal for any
      costs in connection with investigating any such liability, and to
      continue certain insurance coverage for ACM Municipal Securities for a
      six year period.

   Also at the November 20 Meeting, the Board of Directors of Alliance National
Municipal (comprised of the same persons as the Board of ACM Municipal
Securities) approved the proposed Plan. No vote of stockholders of Alliance
National Municipal is required in to approve the Acquisition, although, under
NYSE rules, Alliance National Municipal Securities stockholders must approve
the issuance of common stock of such Fund in connection with the Acquisition.

                                      18



Description of Securities to be Issued

   Under the Plan, Alliance National Municipal will issue shares of common
stock for distribution to ACM Municipal Securities. Under its Charter and
Bylaws, Alliance National Municipal may issue up to 1,999,992,200 shares of
common stock, par value $.001 per share. For information regarding the rights
and privileges associated with the Fund's common stock, see Appendix C, "Other
Information".

   Under the Plan, Alliance National Municipal will also issue additional
shares of Preferred Shares Series M, Preferred Shares Series W, and Preferred
Shares Series TH. Each such preferred stock has a par value of $.001 per share,
and a liquidation preference of $25,000 per share plus an amount equal to
accumulated buy unpaid dividends (whether or not earned or declared).
Generally, unless there is a special dividend payment period, auctions for
Preferred Shares Series M, Preferred Shares Series W and Preferred Shares
Series TH are held on Monday, Wednesday and Thursday, respectively, and
dividends are paid on Tuesday, Thursday and Friday, respectively.

   Preferred stockholders will be entitled to receive dividends that may vary
for successive dividend periods. Dividend rates that are payable are subject to
a maximum rate ceiling that takes into consideration a number of factors, which
include the credit rating assigned to the preferred stock and the duration of
the dividend period. As a general matter, a dividend period can be as little as
7 days or as much as 1,820 days. Generally, a rate period between 7 and 1,820
days may be any number evenly divided by 7. Special rate periods are designated
as any periods greater than 7 days for which, among other things, (i) proper
notice as specified in the Fund's charter has been given to the auction agent
and the holders of the preferred stock and (ii) certain asset maintenance
information required by Moody's and S&P have been set forth in a report. For
additional information regarding the rights and privileges associated with
Alliance National Municipal's preferred stock, see Appendix C, "Other
Information".

Dividends and Other Distributions

   On or before the Closing Date, as defined in the Plan, ACM Municipal
Securities will, if necessary, declare and pay as a distribution substantially
all of its undistributed net investment income, net short-term capital gain,
net long-term capital gain, and net gains from foreign currency transactions as
applicable to maintain its treatment as a regulated investment company.

Surrender and Exchange of ACM Municipal Securities Stock Certificates

   After the Plan's Effective Time, each holder of a certificate (or
certificates) formerly representing shares of ACM Municipal Securities common
stock will be entitled to receive, upon surrender of the certificate, a
certificate representing the number of Alliance National Municipal shares of
common stock distributable as a result of the Acquisition. Promptly after the
Plan's Effective Time, Computershare Trust Company, N.A. will mail to ACM
Municipal Securities' certificate holders instructions and a letter of
transmittal for use in surrendering the certificates. Please do not send share
certificates at this time. Although the certificates will be deemed for all
purposes to evidence ownership of the equivalent number of Alliance National
Municipal shares of common stock, no dividends will be paid to holders of
certificates of ACM Municipal Securities common stock until the holder
surrenders the certificates in accordance with the instructions and letter of
transmittal. Any dividends on Alliance National Municipal shares payable after
the Effective Time, will be paid to the certificate holder, without interest,
when that holder surrenders an ACM Municipal Securities share certificate for
exchange.

   Each ACM Municipal Securities common stockholder will receive the number of
full shares of Alliance National Municipal, plus fractional shares for
stockholders that participate in ACM Municipal Securities' DRIP and cash in
lieu of any fractional shares for non-DRIP stockholders, having an aggregate
NAV that, on the effective date of the Acquisition, is equal to the aggregate
NAV of the stockholder's shares of the ACM Municipal Securities. Holders of ACM
Municipal Securities preferred stock will receive preferred stock of Alliance
National Municipal that have an aggregate liquidation preference and value
equal to the aggregate liquidation preference and value of the outstanding ACM
Municipal Securities preferred stock. Stockholders of ACM Municipal Securities
will recognize no gain or loss, except with respect to any cash received in
lieu of fractional Alliance National Municipal shares by non-DRIP stockholders.

                                      19



Federal Income Tax Consequences

   Subject to certain stated assumptions contained therein, the Funds will
receive an opinion of Seward & Kissel LLP, its counsel, substantially to the
following effect: (i) the Acquisition will constitute a "reorganization" within
the meaning of section 368(a) of the Code and that the Funds will each be "a
party to a reorganization" within the meaning of section 368(b) of the Code;
(ii) a stockholder of ACM Municipal Securities will recognize no gain or loss
on the exchange of the stockholder's shares of ACM Municipal Securities solely
for shares of Alliance National Municipal, except with respect to cash received
in lieu of a fractional share of Alliance National Municipal by non-DRIP
stockholders in connection with the Acquisition; (iii) neither ACM Municipal
Securities nor Alliance National Municipal will recognize any gain or loss upon
the transfer of all of the assets of ACM Municipal Securities to Alliance
National Municipal in exchange for shares of Alliance National Municipal (plus
cash in lieu of certain fractional shares by non-DRIP stockholders) and the
assumption by Alliance National Municipal of the liabilities of ACM Municipal
Securities pursuant to the Plan or upon the distribution of shares of Alliance
National Municipal to stockholders of ACM Municipal Securities (and cash to
non-DRIP stockholders for their fractional shares) in exchange for shares of
ACM Municipal Securities; (iv) the holding period and tax basis of the assets
of ACM Municipal Securities acquired by Alliance National Municipal will be the
same as the holding period and tax basis that ACM Municipal Securities had in
such assets immediately prior to the Acquisition; (v) the aggregate tax basis
of shares of Alliance National Municipal received in connection with the
Acquisition by each stockholder of ACM Municipal Securities (including any
fractional share to which the stockholder may be entitled) will be the same as
the aggregate tax basis of the shares of the ACM Municipal Securities
surrendered in exchange therefor; (vi) the holding period of shares of Alliance
National Municipal received in connection with the Acquisition by each
stockholder of ACM Municipal Securities (including any fractional share to
which the stockholder may be entitled) will include the holding period of the
shares of ACM Municipal Securities surrendered in exchange therefor, provided
that such ACM Municipal Securities shares constitute capital assets in the
hands of the stockholder as of the Closing Date; (vii) Alliance National
Municipal will succeed to the capital loss carryovers of ACM Municipal
Securities, if any, under section 381 of the Code, but the use by Alliance
National Municipal of any such capital loss carryovers (and of capital loss
carryovers of Alliance National Municipal) may be subject to limitation under
section 383 of the Code; and (viii) any gain or loss realized by a non-DRIP
stockholder of ACM Municipal Securities upon the receipt of cash for a
fractional share of Alliance National Municipal common stock to which the
stockholder is entitled will be recognized to the common stockholder and
measured by the difference between the amount of cash received and the basis of
the fractional share and, provided that the ACM Municipal Securities shares
surrendered constitute capital assets in the hands of the stockholder, will be
capital gain or loss. This opinion of counsel will not be binding on the
Internal Revenue Service or a court and there is no assurance that the Internal
Revenue Service or a court will not take a view contrary to those expressed in
the opinion.

   Stockholders of ACM Municipal Securities are encouraged to consult their tax
advisers regarding the effect, if any, of the Acquisition in light of their

                          INFORMATION ABOUT THE FUNDS

   Alliance National Municipal and ACM Municipal Securities are each a
diversified, closed-end management investment companies registered under the
1940 Act and organized as a Maryland corporation in 2001, and 1993,
respectively.

Management of the Funds

   The Board of Directors of each Fund, which is comprised of the same persons,
directs the management of the business and affairs of the Fund. Each Board of
Directors approves all significant agreements between the respective Fund and
persons or companies furnishing services to it, including a Fund's agreements
with the Adviser and the Fund's administrator, custodian and transfer and
dividend disbursing agent. The Board of ACM Municipal Securities approves its
agreement with its administrator, while Alliance National Municipal does not
have a separate administrator. The day-to-day operations of a Fund are
delegated to its officers and the Fund's Adviser, subject to the Fund's
investment objective and policies and to general supervision by the Fund's
Board of Directors. Subsequent to the consummation of the Acquisition, the
directors and officers of Alliance National Municipal will continue to serve as
the directors and officers of Alliance National Municipal after the
Acquisition. The portfolio managers jointly and primarily for the management of
Alliance National Municipal and ACM Municipal Securities are the same, they
are: Michael G. Brooks, Fred S. Cohen, Robert B. Davidson III, and Terrance T.
Hults. Mr. Brooks is a Vice President with the Adviser, with which he has been
associated since prior to 2001. Messrs. Cohen, Davidson III, and Hults are each
a Senior Vice President with the Adviser, with which each has been associated
since prior to 2001. Subsequent to the consummation of the Acquisition, Messrs.
Brooks, Cohen, Davidson III, and Hults will continue to be jointly and
primarily responsible for the day-to-day management of Alliance National
Municipal.

   The SAI provides additional information about the portfolio managers'
compensation, other accounts managed by the portfolio managers, and the
portfolio managers' ownership of securities in Alliance National Municipal.

Advisory Agreement and Fees

   Each Fund's investment adviser is AllianceBernstein L.P. (the "Adviser"),
1345 Avenue of the Americas, New York, New York 10105. The Adviser is a leading
international investment adviser managing client accounts with assets as of
September 30, 2006 totaling more than $659 billion (of which more than $82
billion represented the assets of investment companies). As of September 30,
2006, the Adviser managed retirement assets for many of the largest public and
private employee benefit plans (including 41 of the nations' FORTUNE 100
companies), for public employee retirement funds in 37 states, for investment
companies, and for foundations, endowments, banks and insurance companies
worldwide. The 44 registered investment companies managed by the Adviser,
comprising 125 separate investment portfolios, currently have approximately
4.0 million stockholder accounts.

   Under each Fund's advisory agreement with the Adviser (the "Advisory
Agreement"), the Adviser provides office space, investment advisory services,
and order placement facilities for the Fund and pays all compensation of
directors and officers of the Fund who are affiliated persons of the Adviser.
Under the Advisory Agreement of ACM Municipal Securities, the Fund pays the
Adviser, an investment advisory fee of 0.50% of the average weekly net assets
of the Fund. Under the Advisory Agreement of Alliance National Municipal, the
Fund pays the Adviser, an investment advisory fee of 0.65% of the Fund's
average daily net assets. Alliance National Municipal's advisory fee is
effectively reduced as a result of the Adviser's voluntary agreement to waive a
portion of its fees or reimburse the Fund for expenses in the amount of 0.25%
of the Fund's average daily net assets applicable to common and preferred
stockholders for the first 5 full years of the Fund's operations, 0.20% of the
Fund's average daily net assets applicable to common and preferred stockholders
in year 6, 0.15% in year 7, 0.10% in year 8, and 0.05% in year 9. The Fund is
currently in its fifth year of operation. The Adviser has agreed to waive the
advisory fee increase in the years 8 and 9 and cap the advisory fee at 0.55%.
The Adviser has also agreed to

                                      21



seek approval by the Board of Directors of a new advisory contract that would
have a maximum advisory fee of 0.55%. For the fiscal year ended October 31,
2005, the amount of such fees waived was $1,284,310. The advisory fee for each
Fund is accrued daily and paid monthly.

   The Advisory Agreements by their terms continue in effect from year to year
if such continuance is specifically approved, at least annually, by a majority
vote of the directors of a Fund who neither are interested persons of the Fund
nor have any direct or indirect financial interest in the Advisory Agreement,
cast in person at a meeting called for the purpose of voting on such approval.
A discussion regarding the basis for a Board of Directors approving the
investment advisory contracts of ACM Municipal Securities and Alliance National
Municipal is available in each Fund's Semi-Annual Report to Stockholders for
the fiscal periods ended April 30, 2006.

   The Adviser is the subject of certain legal proceedings relating to market
timing in certain open-end funds advised by the Adviser. A discussion of those
proceedings is presented in Appendix G.

Administrator

   The Adviser serves as administrator for the Funds and in that capacity
performs certain administrative services. The Adviser provides administration
services to Alliance National Municipal under that Fund's Advisory Agreement
and such agreement provides that the Fund will reimburse the Adviser for the
cost of providing certain administrative services. However, the Adviser has
informed the Board that it has no present intention of submitting reimbursement
requests to the Board pursuant to such provision and will not seek
reimbursement in the future without first obtaining the Board's approval. Under
an administrative services agreement, the Adviser performs administrative
services for ACM Municipal Securities.

   ACM Municipal Securities pays a fee under the administrative services
agreement at an annual rate of 0.15% of the average weekly net assets of the
Fund. Such fee is accrued daily and paid monthly. Currently, the Adviser has
voluntarily agreed to waive administrative expenses of the Fund at an annual
rate of 0.10 of 1% of the average weekly net assets of the Fund. The Adviser
has engaged Prudential Investments LLC, an indirect, wholly-owned subsidiary of
Prudential Financial, Inc., to act as sub-administrator. The Adviser, out of
its own assets, pays the Sub-Administrator a monthly fee equal to an annual
rate of 0.10 of 1% of the Fund's average weekly net assets. The
Sub-Administrator prepares financial and regulatory reports for the Fund and
provides other clerical services.

Other Service Providers

   The Acquisition will result in one change to ACM Municipal Securities'
service providers as described below. AllianceBernstein Investor Services, Inc.
("ABIS"), an affiliate of the Adviser, provides certain stockholder services
for the Funds. The Funds compensate ABIS for these services. The Bank of New
York, One Wall Street, New York, NY 10286 serves as the custodian for ACM
Municipal Securities. State Street Bank and Trust Company, 225 Franklin Street,

                              VOTING INFORMATION

   The Board of Directors of ACM Municipal Securities has fixed the close of
business on December 15, 2006 as the Record Date for the determination of
stockholders entitled to notice of, and to vote at, the Meeting and at any
adjournments or postponements thereof. Appendix H to this Prospectus/Proxy
Statement lists the total number of shares of ACM Municipal Securities
outstanding as of December 15, 2006. It also identifies holders of more than
five percent of shares of each Fund, and contains information about the
executive officers and Directors of each Fund and their shareholdings in each
Fund.

   Those stockholders who hold shares directly and not through a broker or
nominee (that is, a stockholder of record) may authorize their proxies to cast
their votes by completing a proxy card and returning it by mail in the enclosed
postage-paid envelope or by telephoning toll free 1-800-331-5817. Owners of
shares held through a broker or nominee (who is the stockholder of record for
those shares) should follow the directions provided to the stockholder by the
broker or nominee to submit voting instructions. Instructions to be followed by
a stockholder of record to authorize a proxy via telephone, including use of
the Control Number on the stockholder's proxy card, are designed to verify
stockholder identities, to allow stockholders to give voting instructions and
to confirm that stockholder instructions have been recorded properly.
Stockholders who authorize proxies by telephone should not also return a proxy
card. A stockholder of record may revoke that stockholder's proxy at any time
prior to exercise thereof by giving written notice to the Secretary of ACM
Municipal Securities at 1345 Avenue of the Americas, New York, New York 10105,
by authorizing a later-dated proxy (either by signing and mailing another proxy
card or, by telephone as indicated above), or by personally voting at the
Meeting.

   Properly executed proxies may be returned with instructions to abstain from
voting or to withhold authority to vote (an "abstention") or represent a broker
"non-vote" (which is a proxy from a broker or nominee indicating that the
broker or nominee has not received instructions from the beneficial owner or
other person entitled to vote shares on a particular matter with respect to
which the broker or nominee does not have the discretionary power to vote).
Approval of the Proposal requires: (i) the affirmative vote by ACM Municipal
Securities common stock and preferred stock holders entitled to cast a majority
of the votes entitled to be cast on the matter, voting together as a single
class (ii) with respect to ACM Municipal Securities preferred stock holders,
voting as a separate class, the affirmative vote of the holders of a "majority
of the outstanding voting securities" of such shares as defined in the 1940
Act, which means the lesser of (i) 67% or more of such shares present or
represented by proxy, if the holders of more than 50% of the outstanding
preferred stock are present or represented by proxy, or (ii) more than 50% of
the outstanding preferred stock of ACM Municipal Securities. Abstentions and
broker non-votes will be considered present for purposes of determining the
existence of a quorum for the transaction of business but will have the effect
of a vote against the Proposal.

   If any proposal, other than the Proposal, properly comes before the Meeting,
the shares represented by proxies will be voted on all such proposals in the
discretion of the person or persons voting the proxies. ACM Municipal
Securities has not received notice of, and is not otherwise aware of, any other
matter to be presented at the Meeting.

   A quorum for the transaction of business by common stockholders and
preferred stockholders of ACM Municipal Securities will consist of the presence
in person or by proxy of the holders of a majority of the shares of the Fund
entitled to vote at the Meeting. In addition, with respect to the separate vote
by preferred stockholders, a quorum will consist of the presence in person or
by proxy of the holders of a majority of the shares of the preferred stock
entitled to vote at the Meeting. In the event that a quorum is not represented
at the Meeting or, even if a quorum is so present, if sufficient votes in favor
of the position recommended by the Board of Directors on the Proposal are not
timely received, the Chairman of the Board may authorize, or the persons named
as proxies may propose and vote for one or more adjournments of the Meeting
with no other notice than announcement at the Meeting, in order to permit
further solicitation of proxies. Shares represented by proxies indicating a
vote against the Proposal will be voted against adjournment.

                                      23



   ACM Municipal Securities has engaged The Altman Group, Inc. (the "Proxy
Solicitor"), 60 East 42/nd/ Street, Suite 405, New York, New York 10165 to
assist in soliciting proxies for the Meetings. The Proxy Solicitor will receive
a fee of approximately $14,000 from the Fund for its solicitation services,
plus reimbursement of out-of-pocket expenses.

              centage restrictions on the

              first restriction is that the

              and premiums paid on op-

              would exceed 5% of the
              market value of the total as-
              sets of the Fund. The second
              restriction is that the ag-
              gregate market value of the
              futures contracts purchased
              by the Fund not exceed 50%

                                  APPENDIX B

                  DESCRIPTION OF PRINCIPAL RISKS OF THE FUNDS

   Among the principal risks of investing in a Fund are market risk, interest
rate risk, credit risk, leveraging risk, derivatives risk, liquidity risk and
management risk. Each of these risks and other risks are more fully described
below. There are no substantial differences in the principal risks to which the
Funds are subject. Each Fund could become subject to additional risks because
the types of investments made by each Fund can change over time.


                       
Market Risk and           This is the risk that the value of a Fund's investments will fluctuate as
Net Asset Value of Shares municipal bond markets fluctuate and that prices overall will decline over
                          shorter or longer-term periods. Shares of common stock of closed-end
                          investment companies, such as the Funds, frequently trade at a discount
                          to their NAVs. Whether an investor will realize gains or losses upon the
                          sale of shares of a Fund does not depend directly upon changes in the
                          Fund's NAV, but rather upon whether the market price of the shares at
                          the time of sale is above or below the investor's purchase price for the
                          shares. The market price of the shares of each Fund is determined by
                          such factors as relative demand for and supply of the shares in the mar-
                          ket, general market and economic conditions, changes in the Fund's
                          NAV and other factors beyond the control of the Fund. This market risk
                          is separate and distinct from the risk that each Fund's NAV may de-
                          crease.

Interest Rate Risk        This is the risk that changes in interest rates will affect the yield and
                          value of a Fund's investments in municipal bonds. When interest rates
                          rise, the value of a Fund's investments tends to fall and this decrease in
                          value may not be offset by higher interest income from new investments.
                          Interest rate risk is generally greater for investment companies like the
                          Funds that invest in municipal bonds with longer maturities or durations.
                          The value of these securities is affected more by changes in interest rates
                          because when interest rates rise, the maturities of these types of securities
                          tend to lengthen and the value of the securities decreases more sig-
                          nificantly, which, in turn reduces the asset coverage on the Funds' pre-
                          ferred stock. In addition, these types of securities are subject to
                          prepayment when interest rates fall, which generally results in lower re-
                          turns because a Fund must reinvest its assets in municipal bonds with
                          lower interest rates.


                                      37




              
Credit Risk      This is the risk that the issuer or the guarantor of a municipal bond, or the
                 counterparty to a derivatives or other contract, will be unable or unwill-
                 ing to make timely payments of interest or principal or to otherwise
                 honor its obligations. The issuer or guarantor may default causing a loss
                 of the full principal amount of a security and any accrued interest. The
                 degree of risk for a particular security may be reflected in its credit rat-
                 ing. Investments in municipal bonds with lower ratings tend to have a
                 higher probability that an issuer will default or fail to meet its payment
                 obligations.

                 Because Alliance National Municipal may invest up to 25% (measured at
                 the time of investment) of its net assets in municipal bonds that are rated
                 below investment grade or, if unrated, determined to be of comparable
                 quality by the Adviser, Alliance National Municipal is more susceptible
                 to credit risk. The prices of these lower grade municipal bonds are more
                 sensitive to negative developments, such as a decline in the issuer's rev-
                 enues or a general economic downturn, than are the prices of higher-
                 grade municipal bonds.

                 Municipal bonds of below investment grade quality (commonly referred
                 to as "junk bonds") are predominantly speculative with respect to the
                 issuer's capacity to pay interest and repay principal when due and there-
                 fore involve a greater risk of default. Municipal bonds in the lowest in-
                 vestment grade category may also be considered to possess some
                 speculative characteristics by certain rating agencies. Any default by an
                 issuer of a municipal bond could have a negative impact on a Fund's
                 ability to pay dividends on its preferred stock and could result in the re-
                 demption of some or all of the preferred stock.

Leverage Risk    The Funds use financial leverage for investment purposes. When a Fund
                 borrows money or otherwise leverages its portfolio, it may be more vola-
                 tile because leverage tends to exaggerate the effect of any increase or
                 decrease in the value of the portfolio's investments. Leverage risk in-
                 cludes the risk associated with the issuance of preferred stock to leverage
                 the a Fund's common stock. If the dividend rate on the preferred stock
                 exceeds the net rate of return on a Fund's portfolio, the leverage will re-
                 sult in a lower NAV than if the Fund were not leveraged, and the Fund's
                 ability to pay dividends and to meet its asset coverage tests would be
                 reduced.

                 Investment by the Fund in derivative instruments may amplify the effects
                 of leverage.

                 Because the management fees received by the Adviser are based on the
                 total net assets of a Fund (including assets acquired with the proceeds of
                 preferred stock), the Adviser has a financial incentive for a Fund to use
                 leverage and issue preferred stock.

Derivatives Risk The Funds may use derivatives. These investment strategies may be risk-
                 ier than other investment strategies and may result in greater volatility for
                 a Fund, particularly during periods of market declines.

Liquidity Risk   Liquidity risk exists when particular investments are difficult to purchase
                 or sell, possibly preventing a Fund from selling out of these illiquid secu-
                 rities at an advantageous price. Derivatives and securities involving sub-
                 stantial market and credit risk tend to involve greater liquidity risk.

Management Risk                 Each Fund is subject to management risk because it is an actively man-
                                aged investment portfolio. The Adviser will apply its investment tech-
                                niques and risk analyses in making investment decisions for each Fund,
                                but there can be no guarantee that its decisions will produce the desired
                                results.

Municipal Bond Market Risk      This is the risk that special factors, such as legislative changes and local
                                and business developments, may adversely affect the yield or value of a
                                Fund's investments in municipal bonds or other municipal securities. The
                                amount of public information available about municipal bonds is gen-
                                erally less than that for corporate equities or bonds and the investment
                                performance of a Fund may therefore be more dependent on the ana-
                                lytical abilities of the Adviser than would be a stock fund or taxable bond
                                fund. The secondary market for municipal bonds, particularly below in-
                                vestment grade municipal bonds in which the Fund may invest, also tends
                                to be less developed and less liquid than many other securities markets,
                                which may adversely affect a Fund's ability to sell its municipal bonds at
                                attractive prices.

Auction Risk                    You may not be able to sell the preferred stock at an auction if the auc-
                                tion fails; that is, if there are more preferred stock offered for sale than
                                there are buyers for those shares. As a result, your investment in pre-
                                ferred stock may be illiquid. Neither the participating broker-dealers nor
                                a Fund are obligated to purchase preferred stock in an auction or other-
                                wise, nor is the Fund required to redeem the preferred stock in the event
                                of a failed auction.

Ratings and Asset Coverage Risk A rating agency could downgrade the preferred stock, which could affect
                                their liquidity and value. In addition, a Fund may be forced to redeem
                                preferred stock to meet regulatory or rating agency requirements. The
                                Fund may also voluntarily redeem preferred stock under certain circum-
                                stances.

Secondary Market Risk           You could receive less than the price you paid for your preferred stock if
                                you sell them outside of an auction, especially when market interest rates
                                are rising. Although participating broker-dealers may maintain a secon-
                                dary trading market in the preferred stock outside of auctions, they are
                                not obligated to do so, and no secondary market may develop or exist at
                                any time for the preferred stock.



                                      39



                                  APPENDIX C

                               OTHER INFORMATION

   The following information provides only a summary of the key features of the
organizational structure, governing documents, and stockholder services of the
Funds.

   Each Fund is organized as a Maryland corporation. The Bylaw provisions that
govern each of the Funds are the same. Unless noted below, there are no
significant differences among the Funds in terms of their respective corporate
organizational structures.

Shares of Common Stock of the Funds

   Alliance National Municipal is authorized to issue 1,999,992,200 shares of
common stock, $.001 par value per share. ACM Municipal Securities is authorized
to issue 99,996,400 shares of common stock, $.01 par value per share. The
charter of Alliance National Municipal provides that the Board of Directors,
without any action by the stockholders of the Fund, may amend the charter from
time to time to increase or decrease the aggregate number of shares of stock or
the number of shares of stock of any class or series that the Fund has
authority to issue. There are no subscription/preemptive or exchange rights
under the charters. Each share of a Fund's common stock has equal voting,
dividend, distribution and liquidation rights subject to the preferential
rights of a Fund's preferred stock. At any time when a Fund's preferred stock
are outstanding, common stockholders will not be entitled to receive any
distributions from a Fund unless all accrued dividends on preferred stock have
been paid, and unless asset coverage (as defined in the 1940 Act) with respect
to the preferred stock would be at least 200% after giving effect to such
distributions. Shares of common stock when issued are duly authorized, fully
paid and nonassessable. Under the rules of the NYSE applicable to listed
companies, each Fund is required to hold an annual meeting of stockholders each
year.

   Holders of the common stock of each Fund are entitled to one vote per share.
All voting rights for the election of directors are non-cumulative, which means
that the holders of more than 50% of the shares of a Fund's stock can elect
100% of the directors then nominated for election if they choose to do so and,
in such event, the holders of the remaining shares of stock will not be able to
elect any directors.

   Each Fund intends to distribute monthly its net investment income to holders
of their common stock. Monthly distributions to common stockholders will
consist of net investment income remaining after the payment of dividends on
outstanding preferred stock. Net capital gains, if any, will be distributed at
least annually to common stockholders to the extent such net capital gains are
not necessary to satisfy the dividend, redemption or liquidation preferences of
any preferred stock. For tax purposes, a Fund will be required, assuming
issuance of preferred stock, to allocate net capital gain and other taxable
income, if any, between common stock and preferred stock in proportion to total
dividends paid to each class for the year in which such net capital gain or
other taxable income is realized. While any preferred stock are outstanding, a
Fund may not declare any cash dividend or other distribution on its common
stock, unless, at the time of such declaration, (a) all accrued preferred stock
dividends have been paid and (b) the NAV of the Fund's portfolio (determined
after deducting the amount of such dividend or other distribution) is at least
200% of the liquidation value of the outstanding preferred stock (expected to
equal the original purchase price per share plus any accrued and unpaid
dividends thereon). This limitation on a Fund's ability to make distributions
on its common stock could under certain circumstances impair the ability of the
Fund to maintain its qualification for taxation as a regulated investment
company.

Description of Preferred Stock

   Alliance National Municipal has authorized, issued and outstanding 7,800
shares of Auction Preferred Stock as follows: 1,950 Series M Preferred Shares,
1,950 Series T Preferred Shares, 1,950 Series W Preferred Shares and 1,950
Series TH Preferred Shares. The preferred shares have a liquidation value of
$25,000 per share plus accumulated unpaid dividends. Alliance National
Municipal's preferred stock will pay dividends based on a rate set at Auctions,
normally held weekly, except in the case of special rate periods. For Series M
Preferred Shares, Series T Preferred Shares, Series W Preferred Shares and
Series TH Preferred Shares auctions are generally held

                                      40



respectively, on Mondays, Tuesdays, Wednesdays and Thursdays. Dividends are
generally payable, when, as and if authorized by the Board and declared by the
Fund: on Series M Preferred Shares on Tuesdays; on Series T Preferred Shares on
Wednesdays; on Series W Preferred Shares on Thursdays and on Series TH
Preferred Shares on Fridays.

   ACM Municipal Securities has authorized, issued and outstanding 3,600 shares
of Auction Preferred Stock as follows: 1,200 Series A Preferred Shares, 1,200
Series B Preferred Shares and 1,200 Series C Preferred Shares. The preferred
shares have a liquidation value of $25,000 per share plus accumulated unpaid
dividends. ACM Municipal Securities' preferred stock will pay dividends based
on a rate set at Auctions, normally held weekly, except in the case of special
rate periods. For Series A Preferred Shares, Series B Preferred Shares, and
Series C Preferred Shares auctions are generally held, respectively, on
Wednesdays, Mondays, and Thursdays. Dividends are generally payable, when, as
and if authorized by the Board and declared by the Fund: on Series A Preferred
Shares on Thursdays; on Series B Preferred Shares on Tuesdays; and on Series C
Preferred Shares on Fridays.

   If dividends are payable on a day that is not a business day then such
dividends will be paid on such shares on the first business day that falls
after that day.

   Each series of preferred stock of a Fund will rank on parity with any other
series of preferred stock of that Fund as to the payment of dividends and the
distribution of assets upon liquidation. Preferred shares are, when issued,
fully paid and non-assessable and have no preemptive or conversion rights or
rights to cumulative voting. The preferred stock of each series of each Fund
has a liquidation value of $25,000 per share plus accumulated, unpaid dividends.

   Except as otherwise provided in a Fund's charter or as otherwise required by
law, preferred stockholders will have equal voting rights with common
stockholders (one vote per share) and will vote together with common
stockholders and any other preferred stockholders as a single class. A Fund's
charter sets forth matters on which a Fund's preferred stockholders will vote
separately as a single class.

   In connection with the election of a Fund's Directors, holders of
outstanding preferred stock, voting as a separate class, are entitled to elect
two of the Fund's Directors, and the remaining Directors are elected by common
stockholders and preferred stockholders, voting together as a single class. The
Funds' charters sets forth circumstances relating to outstanding and unpaid
dividends due to preferred stockholders that would entitle such stockholders to
elect members to the Board that would result in such stockholders having
elected a majority of the Directors to the Board.

   (i) Redemptions

   The redemption provisions pertaining to the preferred stock of each Fund are
similar. It is anticipated that preferred stock of each Fund will generally be
redeemable at the option of the applicable Fund at a price equal to the
liquidation preference of each ($25,000 per share), plus accumulated but unpaid
dividends (whether or not earned or declared) to the date of redemption plus,
in certain circumstances, a redemption premium. Preferred shares of each Fund
are also subject to mandatory redemption at a price equal to their liquidation
preference plus accumulated but unpaid dividends (whether or not earned or
declared) to the date of redemption upon the occurrence of certain specified
events, such as the failure of a Fund to maintain asset coverage requirements
for its preferred stock specified by Moody's and S&P in connection with their
issuance of ratings on their preferred stock.

   (ii) Liquidation

   Subject to the rights of holders of any series or class or classes of shares
ranking on parity with a Fund's preferred stock with respect to the
distribution of assets upon liquidation of a Fund, upon liquidation of a Fund,
whether voluntary or involuntary, the holders of preferred stock then
outstanding will be entitled to receive and to be paid out of the assets of the
Fund available for distribution to its stockholders, before any payment or
distribution shall be made on the common stock or on any other class of stock
of the Fund ranking junior to the

                                      41



preferred stock, an amount equal to the liquidation preference with respect to
such shares, plus an amount equal to all dividends thereon (whether or not
earned or declared) accumulated but unpaid to (but not including) the date of
final distribution in same-day funds, together with any applicable gross-up
payments (i.e., to account for certain federal income tax liability
consequences) in connection with the liquidation of the Fund. After the payment
to the holders of preferred stock of the full preferential amounts provided for
as described herein, the holders of preferred stock shall have no right or
claim to any of the remaining assets of a Fund.

   Neither the sale of all or substantially all the property or business of the
Fund, nor the merger or consolidation of a Fund into or with any other
corporation nor the merger or consolidation of any other corporation into or
with a Fund, shall be a liquidation, whether voluntary or involuntary, for the
purposes of the foregoing paragraph.

   The terms of the Series M, Series T, Series W and Series TH Preferred Shares
of Alliance National Municipal provide that, in determining whether a
distribution (other than upon voluntary or involuntary dissolution) by
dividend, redemption or other acquisition of shares of stock of the Fund or
otherwise is permitted under the MGCL, amounts that would be needed, if the
Fund were to be dissolved at the time of the distribution, to satisfy the
preferential rights upon dissolution of the holders of such series of Preferred
Shares will not be added to the Fund's total liabilities.

   (iii) Ratings

   The preferred stock of each Fund has been assigned a rating of "AAA" from
S&P and "Aaa" from Moody's. Each Fund intends that, so long as its preferred
shares are outstanding, the composition of its portfolio will reflect
guidelines established by S&P and Moody's in connection with each Fund's
receipt of a rating for such shares of at least "AAA" from S&P and "Aaa" from
Moody's. S&P and Moody's, which are nationally recognized statistical rating
organizations, issue ratings for various securities reflecting the perceived
creditworthiness of such securities. The guidelines for rating such preferred
stock have been developed by S&P and Moody's and are designed to ensure that
assets underlying outstanding debt or preferred stock will be varied
sufficiently and will be of sufficient quality and amount to justify investment
grade ratings. The guidelines do not have the force of law but have been
adopted by each Fund in order to satisfy current requirements necessary for S&P
and Moody's to issue the above-described ratings for preferred stock, which
ratings generally are relied upon by institutional investors in purchasing such
securities. The guidelines provide a set of tests for portfolio composition and
asset coverage that supplement (and in some cases are more restrictive than)
the applicable requirements under the 1940 Act.

   Each Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by S&P or Moody's. Failure to
adopt any such modifications, however, may result in a change in the ratings
described above or a withdrawal of the ratings altogether. In addition, any
rating agency providing a rating for a Fund's preferred stock, at any time, may
change or withdraw any such rating. As set forth in each Fund's Articles
Supplementary, each Fund, without stockholder approval, may modify certain
definitions or restrictions that have been adopted by the Fund pursuant to the
rating agency guidelines, provided the Board of a Fund has obtained written
confirmation from S&P and Moody's that any such change would not impair the
ratings then assigned by S&P and Moody's to the preferred stock.

Board of Directors

   Each Fund has a Board of Directors that is divided into three classes of
Directors. The terms of the Directors in a class are staggered so that for a
given year only one class of Directors will be up for election by a Fund's
stockholders. The Funds believe that classification of the Board of Directors
will help to ensure the continuity and stability of a Fund's business
strategies and policies as determined by the Board of Directors.

   The classified board provision could have the effect of making the
replacement of incumbent Directors more time-consuming and difficult. At least
two annual meetings of stockholders, instead of one, will generally be required
to effect a change in a majority of the Board of Directors. Thus, the
classified board provision could increase the likelihood that incumbent
Directors will retain their positions. The staggered terms of Directors may

                                      42



delay, defer, or prevent a tender offer or an attempt to change control of a
Fund, although the tender offer or change in control might be in the best
interest of the stockholders.

   The procedures available to a Fund's stockholders for calling stockholders'
meetings for the removal of directors are the same. Under Maryland law and the
Funds' charters, a director may be removed only with cause at a meeting duly
called and at which a quorum is present by the affirmative vote of seventy-five
percent of all the votes entitled to be cast.

Stockholder Meetings

   The Bylaws of the Funds provide that special meetings of stockholders for
any purpose shall be called by a Fund's Secretary upon the written request of
holders of shares entitled to cast not less than a majority of the votes
entitled to be cast at a meeting. Special meetings may also be called by the
Board of Directors and certain officers.

   Except as otherwise required by law or a Fund's charter, the presence in
person or by proxy of the holders entitled to cast a majority of the votes
entitled to be cast constitutes a quorum at any meeting of stockholders of a
Fund. Pursuant to each Fund's charter, except in instances involving
extraordinary corporate action, such as a merger, amendments to its charter or
removal of a director, generally, the vote of a majority of the aggregate
number of votes entitled to be cast on a matter is required in order to take or
authorize any such action for which approval of the stockholders is required.
The Bylaws of each Fund provides that each director shall be elected by the
affirmative vote of the holders of a majority of the votes entitled to be cast;
for other matters, when a quorum is present, the affirmative vote of a majority
of the votes cast shall decide any question brought before such meeting unless
a statute or charter requires a higher voting margin.

Dividend Reinvestment Plans

   Stockholders of ACM Municipal Securities whose common shares are registered
in their own names will automatically be enrolled as participants in that
Fund's Dividend Reinvestment and Cash Purchase Plan (the "DRIP"), under which
dividends and capital gain distributions to stockholders will be paid or
reinvested in additional shares of the Fund (the "Dividend Shares"). Procedures
are available to stockholders who do not wish to participate in the DRIP.
Stockholders of Alliance National Municipal whose common shares are registered
in their own names may elect to participate in that Fund's DRIP. Computershare
Trust Company, N.A. ("Agent") acts as agent to stockholders under the Plan.
Stockholders whose shares are held in the name of a broker or nominee should
contact such broker or nominee to determine whether or how they may participate
in the DRIP. Assuming the Acquisition is approved, the DRIP stockholders of ACM
Municipal Securities will automatically be enrolled in the DRIP for Alliance
National Municipal.

   If the Board declares an income distribution or determines to make a capital
gain distribution payable either in shares or in cash, as holders of a Fund's
common stock may have elected, non-participants in the DRIP will receive cash
and participants in the Plan will receive the equivalent in shares of common
stock of the Fund valued as follows:

    (i)If the shares of common stock are trading at NAV or at a premium above
       net asset value at the time of valuation, the Fund will issue new shares
       at the greater of net asset value or 95% of the then current market
       price.

   (ii)If the shares of common stock are trading at a discount from NAV at the
       time of valuation, the Agent will receive the dividend or distribution
       in cash and apply it to the purchase of the Fund's shares of common
       stock in the open market on the NYSE or elsewhere, for the participants'
       accounts. Such purchases will be made on or shortly after the payment
       date for such dividend or distribution and in no event more than 30 days
       after such date except where temporary curtailment or suspension of
       purchase is necessary to comply with Federal securities laws. If, before
       the Agent has completed its purchases, the market price exceeds the NAV
       of a share of common stock, the average purchase price per share paid by
       Agent may exceed the NAV of the Fund's shares of common stock, resulting
       in the acquisition of fewer shares than if the dividend or distribution
       had been paid in shares issued by the Fund.

                                      43



   The Agent will maintain all stockholders' accounts in the DRIP and furnish
written confirmation of all transactions in the account, including information
needed by stockholders for tax records. Shares in the account of each DRIP
participant will be held by the Agent in non-certificate form in the name of
the participant, and each stockholder's proxy will include those shares
purchased or received pursuant to the Plan.

   There will be no charges with respect to shares issued directly by a Fund to
satisfy the dividend reinvestment requirements. However, each participant will
pay a pro rata share of brokerage commissions incurred with respect to the
Agent's open market purchases of shares. In each case, the cost per share of
shares purchased for each stockholder's account will be the average cost,
including brokerage commissions, of any shares purchased in the open market
plus the cost of any shares issued by a Fund.

   The automatic reinvestment of dividends and distributions will not relieve
participants of any income taxes that may be payable (or required to be
withheld) on dividends and distributions.

   Experience under a DRIP may indicate that changes are desirable.
Accordingly, a Fund reserves the right to amend or terminate the DRIP as
applied to any voluntary cash payments made and any dividend or distribution
paid subsequent to written notice of the change sent to participants in the
Plan at least 90 days before the record date for such dividend or distribution.
The Plan may also be amended or terminated by the Agent on at least 90 days'
written notice to participants in the Plan.

   All correspondence concerning the DRIPs for the Funds should be directed to
Computershare Trust Company N.A., P.O. Box 43010, Providence, RI 02940-3011.

Tender Offer/Share Repurchase Policies

   In recognition that their shares may trade at a discount, both Funds have
voluntary share repurchase and tender offer policies. The policies differ
somewhat. ACM Municipal Securities' policy states that "the Board has
determined that it would be in the best interests" of stockholders for the Fund
to take action to attempt to reduce or eliminate a discount. Alliance National
Municipal's policy states that the Fund "may consider" a share repurchase or
tender offer if the Fund's shares trade at a substantial discount for an
extended period of time. In addition, ACM Municipal Securities' policy provides
that the Fund may "from time to time" take action either to repurchase shares
or make a tender offer, while Alliance National Municipal's policy states that
the Fund has "no present intention" to repurchase shares. After the
Acquisition, Alliance National Municipal will retain its current voluntary
tender offer/share repurchase policy.

Possible Future Conversion to Open-End Investment Company

   A Fund's Board of Directors may also from time to time consider submitting
for a stockholder vote a proposal to convert the Fund to an open-end investment
company in an attempt to reduce or eliminate the significant market discounts
from NAV. A Fund's charter requires the affirmative vote or consent of holders
of at least seventy-five percent (75%) of each class of the Fund's shares
entitled to vote on the matter to authorize a conversion of the Fund from a
closed-end to an open- end investment company. This seventy-five percent
(75%) stockholder approval requirement is higher than is required under the
1940 Act.

   If a Fund converted to an open-end company, it would be required to redeem
all preferred stock then outstanding (requiring in turn that it liquidate a
portion of its investment portfolio), and the Fund's common shares likely would
no longer be listed on the NYSE. Stockholders of an open-end investment company
may require the company to redeem their shares on any business day (except in
certain circumstances as authorized by or under the 1940 Act) at their net
asset value, less such redemption charge, if any, as might be in effect at the
time of redemption. In order to avoid maintaining large cash positions or
liquidating favorable investments to meet redemptions, open-end companies
typically engage in a continuous offering of their shares. Open-end companies
are thus subject to periodic asset in-flows and out-flows that can complicate
portfolio management.

   The repurchase by the Fund of its shares at prices below NAV will result in
an increase in the NAV of those shares that remain outstanding. However, there
can be no assurance that share repurchases or tender offers at or below NAV
will result in a Fund's shares trading at a price equal to their NAV.
Nevertheless, the fact that a

                                      44



Fund's shares may be the subject of repurchase or tender offers at NAV from
time to time, or that the Fund may be converted to an open-end company, may
reduce any spread between market price and NAV that might otherwise exist.

   In addition, a purchase by a Fund of its shares would decrease the Fund's
total assets, which would likely have the effect of increasing the Fund's
expense ratio and may also require the redemption of a portion of any
outstanding preferred stock in order to maintain coverage ratios. Any purchase
by a Fund of its common shares at a time when preferred shares are outstanding
will increase the leverage applicable to the outstanding common shares then
remaining.

Certain Anti-Takeover Provisions of the Funds' Charters and Bylaws

   The Funds presently have provisions in their charters and Bylaws (together,
the "Charter Documents") that are intended to limit (i) the ability of other
entities or persons to acquire control of a Fund, (ii) a Fund's freedom to
engage in certain transactions, or (iii) the ability of a Fund's directors or
stockholders to amend the Charter Documents or effect changes in the Fund's
management. These provisions of the Charter Documents may be regarded as
"anti-takeover" provisions.

   The Board of Directors of each Fund is divided into three classes, each
having a term of three years. At each annual meeting of stockholders, the term
of one class of directors expires. Accordingly, only those directors in one
class may be changed in any one year, and it would require two years to change
a majority of the Board of Directors (although under Maryland law procedures
are available for the removal of directors even if they are not then standing
for reelections and under SEC regulations procedures are available for
including stockholder proposals in management's annual proxy statement). Such a
system of electing directors may have the effect of maintaining the continuity
of management and, thus, make it more difficult for a Fund's stockholders to
change the majority of directors. Generally, under a Fund's charter, the
affirmative vote of the stockholders entitled to cast a majority of the votes
entitled to be cast is required for the consolidation of the Fund with another
corporation, a merger of the Fund with or into another corporation (except for
certain mergers in which the Fund is the successor), a statutory share exchange
in which the Fund is not the successor, a sale or transfer of all or
substantially all of the Fund's assets, the dissolution of the Fund and most
amendments to the Fund's Charter. In addition, the affirmative vote of 75%
(which is higher than that required under Maryland law or the 1940 Act) of the
outstanding shares of common stock of a Fund is required generally to authorize
any of the following transactions or to amend the provisions of the Charter
relating to such transactions:

    (i)merger, consolidation or statutory share exchange of the Fund with or
       into any other corporation;

   (ii)issuance of any securities of the Fund to any person or entity for cash;

  (iii)sale, lease or exchange of all or any substantial part of the assets of
       the Fund to any entity or person (except assets having an aggregate fair
       market value of less than $1,000,000); or

   (iv)sale, lease or exchange to the Fund, in exchange for securities of the
       Fund, of any assets of any entity or person (except assets having an
       aggregate fair market value of less than $1,000,000);

   if such corporation, person or entity is directly, or indirectly through
affiliates, the beneficial owner of more than 5% of the outstanding shares of
the Fund (a "principal stockholder"). However, such vote would not be required
where, under certain conditions, the Board of Directors approves the
transaction, although in certain cases involving merger, consolidation or
statutory share exchange or sale of all or substantially all of a Fund's assets
the affirmative vote of a majority of the outstanding shares of the Fund would
nevertheless be required.

   The provisions of the Charter Documents described above and a Fund's right
to repurchase or make a tender offer for its common stock could have the effect
of depriving the owners of shares of opportunities to sell their shares at a
premium over prevailing market prices, by discouraging a third party from
seeking to obtain control of the Fund in a tender offer or similar transaction.
The overall effect of these provisions is to render more difficult the
accomplishment of a merger or the assumption of control by a principal
stockholder. However, they provide the advantage of potentially requiring
persons seeking control of the Fund to negotiate with its management

                                      45



regarding the price to be paid and facilitating the continuity of the Fund's
management and investment objective and policies. The Board of Directors of
each Fund has considered the foregoing anti-takeover provisions and concluded
that they are in the best interests of the Fund and its stockholders.

Limitation of Liability of Directors and Officers; Indemnification

   The charter of each Fund provides that, to the fullest extent that
limitations on the liability of directors and officers are permitted by
Maryland law, no director or officer of the Fund shall have any liability to
the Fund or its stockholders for money damages. The charter and Bylaws of each
of the Funds provide that each Fund shall indemnify its officers and directors,
as applicable, to the maximum extent permitted by Maryland law. This
indemnification does not protect any such person against any liability to a
Fund or any stockholder thereof to which such person would otherwise be subject
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the satisfaction of such person's office.

Purchase and Sale Information

   Purchase and sale procedures for the Funds' common stock are substantially
similar. Investors typically purchase and sell shares of the Funds through a
registered broker-dealer on the NYSE, thereby incurring a brokerage commission
set by the broker-dealer. Alternatively, investors may purchase or sell shares
of the Funds through privately negotiated transactions with existing
stockholders.

   The purchase and sale procedures with respect to the Funds' preferred stock
are substantially similar. The preferred stock are not listed on an exchange
but may be bought and sold at an auction that is normally held weekly by
submitting orders to a participating broker-dealer. In addition to the
auctions, participating broker-dealers may maintain a secondary trading market
in preferred stock outside of the auctions, but may discontinue this activity
at any time.

                                 set value per Acquiring Fund Common Stock Share and the Acquired
                                 Fund determines the net value of the Assets.

                                 then subtracting liabilities and the value of the liquidation preference
                                 applicable to a Fund's preferred shares and then dividing the balance by
                                 the number of shares of common stock that are outstanding.


2. Regulatory Filings

   The Acquiring Fund shall promptly prepare and file the N-14 Registration
Statement with the SEC, and the Acquiring Fund and the Acquired Fund also shall
make any other required or appropriate filings with respect to the actions
contemplated hereby.

3. Stockholder Action

   As soon as practicable after the effective date of the N-14 Registration
Statement, the Acquired Fund shall hold a stockholders meeting to consider and
approve the Acquisition and this Plan and such other matters as the Board of
Directors may determine. Such approval by the stockholders of the Acquired Fund
shall, to the extent necessary to permit the consummation of the transactions
contemplated herein without violating any investment objective, policy or
restriction of the Acquired Fund, be deemed to constitute approval by the
stockholders of a temporary amendment of any investment objective, policy or
restriction that would otherwise be inconsistent with or violated upon the
consummation of such transactions solely for the purpose of consummating such
transactions.

                                      48



4. Transfer of the Acquired Fund's Assets.

   The Acquiring Fund and the Acquired Fund shall take the following steps with
respect to the Acquisition, as applicable:

    (a)On or prior to the Closing Date, the Acquired Fund shall pay or provide
       for the payment of all of the Liabilities, expenses, costs and charges
       of or attributable to the Acquired Fund that are known to the Acquired
       Fund and that are due and payable prior to or as of the Closing Date.

    (b)Prior to the Effective Time, except to the extent prohibited by Rule
       19b-1 under the 1940 Act, the Acquired Fund will declare to Acquired
       Fund stockholders of record a dividend or dividends which, together with
       all previous such dividends, shall have the effect of distributing
       (a) all the excess of (i) Acquired Fund's investment income excludable
       from gross income under section 103(a) of the Code over (ii) Acquired
       Fund's deductions disallowed under section 265 and 171(a)(2) of the
       Code, (b) all of Acquired Fund's investment company taxable income (as
       defined in Code section 852), (computed in each case without regard to
       any deduction for dividends paid), and (c) all of Acquired Fund's net
       realized capital gain (as defined in Code section 1222), if any (after
       reduction for any capital loss carryover), in each case for both the
       taxable year ending on [      ], and the short taxable year beginning on
       [      ], and ending on the Closing Date. Such dividends will be made to
       ensure continued qualification of the Acquired Fund as a "regulated
       investment company" for tax purposes and to eliminate fund-level tax.

    (c)At the Effective Time, pursuant to Articles of Transfer accepted for
       record by the State Department of Assessments and Taxation of Maryland
       (the "SDAT"), the Acquired Fund shall assign, transfer, deliver and
       convey the Assets to the Acquiring Fund, subject to the Liabilities. The
       Acquiring Fund shall then accept the Assets and assume the Liabilities
       such that at and after the Effective Time (i) the Assets at or after the
       Effective Time shall become and be assets of the Acquiring Fund, and
       (ii) the Liabilities at the Effective Time shall attach to the Acquiring
       Fund, and shall be enforceable against the Acquiring Fund to the same
       extent as if initially incurred by the Acquiring Fund.

    (d)Dividends on the preferred shares of the Acquired Fund shall accumulate
       to and include the Closing Date and then cease to accumulate. At or
       prior to the Closing, the Acquired Fund will declare all accumulated but
       unpaid dividends on the preferred shares of the Acquired Fund up to and
       including the Closing Date, such dividends to be paid to holders thereof
       on the applicable dividend payment date corresponding to a particular
       series of preferred shares of the Acquired Fund.

    (e)Within a reasonable time prior to the Closing Date, the Acquired Fund
       shall provide, if requested, a list of the Assets to the Acquiring Fund.
       The Acquired Fund may sell any asset on such list prior to the Effective
       Time. After the Acquired Fund provides such list, the Acquired Fund will
       not acquire any additional securities or permit to exist any
       encumbrances, rights, restrictions or claims not reflected on such list,
       without the approval of the Acquiring Fund. Within a reasonable time
       after receipt of the list and prior to the Closing Date, the Acquiring
       Fund will advise the Acquired Fund in writing of any investments shown
       on the list that the Acquiring Fund has determined to be inconsistent
       with its investment objective, policies and restrictions. The Acquired
       Fund will dispose of any such securities prior to the Closing Date to
       the extent practicable and consistent with applicable legal
       requirements, including the Acquired Fund's investment objectives,
       policies and restrictions. In addition, if the Acquiring Fund determines
       that, as a result of the Acquisition, the Acquiring Fund would own an
       aggregate amount of an investment that would exceed a percentage
       limitation applicable to the Acquiring Fund, the Acquiring Fund will
       advise the Acquired Fund in writing of any such limitation and the
       Acquired Fund shall dispose of a sufficient amount of such investment as
       may be necessary to avoid the limitation as of the Effective Time, to
       the extent practicable and consistent with applicable legal
       requirements, including the Acquired Fund's investment objectives,
       policies and restrictions.

                                      49



    (f)The Acquired Fund shall assign, transfer, deliver and convey the Assets
       to the Acquiring Fund at the Effective Time on the following basis:

       (1)The value of the Assets less the Liabilities, both determined as of
          the Valuation Time, shall be divided by the then NAV of one Acquiring
          Fund Common Stock Share, and, in exchange for the transfer of the
          Assets, the Acquiring Fund shall simultaneously issue and deliver to
          the Acquired Fund the number of full Acquiring Fund Common Stock
          Shares so determined that are allocable to all shares held by or for
          those stockholders of the Acquired Fund on a stockholder by
          stockholder basis plus fractional Acquiring Fund Common Stock Shares,
          rounded to the second decimal place or such other decimal place as
          the parties may agree to in writing, allocable to those stockholders
          of the Acquired Fund that at the Effective Time participate in the
          Acquired Fund's Dividend Reinvestment Plan ("DRIP Stockholders"),
          regardless of whether the shares of the Acquired Fund with respect to
          which such fractional Acquiring Fund Common Stock Shares are to be
          issued and delivered are held by or for the DRIP Stockholders
          directly or in the Acquired Fund's Dividend Reinvestment Plan. The
          Acquiring Fund shall at the same time deliver to the Acquired Fund
          cash in lieu of any fractional Acquiring Fund Common Stock Shares
          allocable to those stockholders of the Acquired Fund that are not
          DRIP Stockholders;

       (2)[      ] Series M Preferred Shares, [      ] Series W Preferred
          Shares and [      ] Series TH Preferred Shares shall be issued in
          exchange for [      ] Series B Preferred Shares, Series A Preferred
          Shares, and Series C Preferred Shares of the Acquired Fund, so that a
          preferred stockholder, respectively, of the Acquired Fund shall
          receive such Acquiring Fund Preferred Shares that have an aggregate
          liquidation preference and value equal to the preferred shares
          previously held by the stockholder of the Acquired Fund. The
          liquidation preference of the preferred shares of the Acquired Fund
          and the Acquiring Fund Preferred Shares is $       per share.

       (3)The NAV of the Acquiring Fund Common Stock Shares to be delivered to
          the Acquired Fund shall be determined as of the Valuation Time in
          accordance with the Acquiring Fund's then applicable valuation
          procedures, and the net value of the Assets to be conveyed to the
          Acquiring Fund shall be determined as of the Valuation Time in
          accordance with the then applicable valuation procedures of the
          Acquired Fund; and

       (4)The portfolio securities of the Acquired Fund shall be made available
          by the Acquired Fund to       , as custodian for the Acquiring Fund
          (the "Custodian"), for examination no later than five business days
          preceding the Valuation Time. On the Closing Date, such portfolio
          securities and all the Acquired Fund's cash shall be delivered by the
          Acquired Fund to the Custodian for the account of the Acquiring Fund,
          such portfolio securities to be duly endorsed in proper form for
          transfer in such manner and condition as to constitute good delivery
          thereof in accordance with the custom of brokers or, in the case of
          portfolio securities held in the U.S. Treasury Department's
          book-entry system or by The Depository Trust Company, Participants
          Trust Company or other third party depositories, by transfer to the
          account of the Custodian in accordance with Rule 17f-4, Rule 17f-5 or
          Rule 17f-7, as the case may be, under the 1940 Act and accompanied by
          all necessary federal and state stock transfer stamps or a check for
          the appropriate purchase price thereof. The cash delivered shall be
          in the form of currency or certified or official bank checks, payable
          to the order of       , the Custodian, or shall be wired to an
          account pursuant to instructions provided by the Acquiring Fund.

    (g)Promptly after the Closing Date, the Acquired Fund will deliver to the
       Acquiring Fund a Statement of Assets and Liabilities of the Acquired
       Fund as of the Closing Date.

                                      50



5. Liquidation and Dissolution of the Acquired Fund, Registration of Acquiring
   Fund Common Stock Shares and Acquiring Fund Preferred Shares and Access to
   Records.

   The Acquired Fund and the Acquiring Fund also shall take the following
steps, as applicable:

    (a)At or as soon as reasonably practical after the Effective Time, the
       Acquired Fund shall (i) liquidate by transferring pro rata to its common
       stock holders of record, the Acquiring Fund Common Stock Shares and cash
       it receives pursuant to Section 4(f)(1) of this Plan and by transferring
       to its preferred stock holders of record, the Acquiring Fund Preferred
       Shares it receives pursuant to Section 4(f)(2) of this Plan and
       (ii) dissolve. The Acquiring Fund shall record on its books the
       ownership by the Acquired Fund's stockholders of the Acquiring Fund
       Common Stock Shares and Acquiring Fund Preferred Shares so transferred
       to such stockholders, and the Acquired Fund shall simultaneously cancel
       on its books all of the issued and outstanding shares of the Acquired

       litigation, proceeding or investigation. Subject to the foregoing, there
       are no facts that the Acquired Fund has reason to believe are likely to
       form the basis for the institution of any such claim, action, suit,
       investigation or proceeding against the Acquired Fund. The Acquired Fund
       is not a party to nor subject to the provisions of any order, decree or
       judgment of any court or governmental body that adversely affects, or is
       reasonably likely to adversely affect, its financial condition, results

       asserted with respect to such returns. To the best of the Acquired
       Fund's knowledge, it will not have any tax deficiency or liability
       asserted against it or question with respect thereto raised, and it will
       not be under audit by the Internal Revenue Service or by any state or
       local tax authority for taxes in excess of those already paid. The
       Acquired Fund will timely file its federal income tax return for each
       subsequent taxable year including its current taxable year.

       "regulated investment company," and the provisions of section 851

       be issued to the Acquired Fund pursuant to paragraph 4(f)(2) will not be
       acquired for the purpose of making any distribution thereof other than
       to the Acquired Fund Stockholders as provided in paragraph 4(f)(1) and

          the sale of a fractional share of the Acquiring Fund to which the
          stockholder is entitled will be recognized to the stockholder and
          measured by the difference between the amount of cash received and
          the basis of the fractional share and, provided that the Acquired
          Fund shares surrendered constitute capital assets in the hands of the
          stockholder, will be a capital gain or loss.

       The opinion will be based on certain factual certifications made by
       officers of the Funds and will also be based on customary assumptions
       and subject to certain qualifications. The opinion is not a guarantee
       that the tax consequences of the Acquisition will be as described above.

       Notwithstanding this subparagraph (e), Seward & Kissel LLP will express
       no view with respect to the effect of the Acquisition on any transferred
       asset as to which any unrealized gain or loss is required to be
       recognized at the end of a taxable year (or on the termination or
       transfer thereof) under federal income tax principles. Each Fund shall
       agree to make and provide additional representations to Seward & Kissel
       LLP with respect to the Funds that are reasonably necessary to enable
       Seward & Kissel LLP to deliver the tax opinion. Notwithstanding anything
       in this Plan to the contrary, neither Fund may waive in any material
       respect the conditions set forth under this subparagraph (e).

    (f)The N-14 Registration Statement shall have become effective under the
       1933 Act as to the Acquiring Fund Common Stock Shares and Acquiring Fund
       Preferred Shares, and the SEC shall not have instituted and to the
       knowledge of the Acquiring Fund is not contemplating instituting, any
       stop order suspending the effectiveness of the N-14 Registration
       Statement.

    (g)No action, suit or other proceeding shall be threatened or pending
       before any court or governmental agency in which it is sought to
       restrain or prohibit, or obtain damages or other relief in connection
       with, the Acquisition.

    (h)The SEC shall not have issued any unfavorable advisory report under
       Section 25(b) of the 1940 Act nor instituted any proceeding seeking to
       enjoin consummation of the Acquisition under Section 25(c) of the 1940
       Act.

    (i)Neither party shall have terminated this Plan with respect to the
       Acquisition pursuant to Section 13 of this Plan.

    (j)The NYSE shall have approved, upon official notice of issuance, the
       listing of the Acquiring Fund Common Stock Shares to be issued and
       delivered to the Acquired Fund pursuant hereto.

9. Conditions to the Obligations of the Acquired Fund.

   The obligations of the Acquired Fund with respect to the Acquisition shall
be subject to the following conditions precedent:

    (a)The Acquired Fund shall have received an opinion of Seward & Kissel LLP,
       counsel to the Acquiring Fund, in form and substance reasonably
       satisfactory to the Acquired Fund and dated as of the Closing Date,
       substantially to the effect that:

       (1)The Acquiring Fund is a corporation duly incorporated, existing and
          in good standing under the laws of the State of Maryland and is a
          closed-end, management investment company registered under the 1940
          Act and duly registered under the 1934 Act;

       (2)This Plan has been duly authorized, executed and, so far is known to
          such counsel, delivered by the Acquiring Fund and, assuming the N-14
          Registration Statement referred to in Section 2 of this Plan does not
          contain any material misstatements or omissions, and assuming due
          authorization,

                                      57



          execution and delivery of this Plan by the Acquired Fund, represents
          a legal, valid and binding contract, enforceable in accordance with
          its terms, subject to the effect of bankruptcy, insolvency,
          moratorium, fraudulent conveyance and transfer and similar laws
          relating to or affecting creditors' rights generally and court
          decisions with respect thereto, and further subject to the
          application of equitable principles in any proceeding, whether at law
          or in equity or with respect to the enforcement of provisions of the
          Plan and the effect of judicial decisions which have held that
          certain provisions are unenforceable when their enforcement would
          violate an implied covenant of good faith and fair dealing or would
          be commercially unreasonable or when default under the Plan is not
          material;

       (3)The Acquiring Fund Common Stock Shares and Acquiring Fund Preferred
          Shares to be delivered as provided for by this Plan are duly
          authorized and, when issued in accordance with this Plan and the
          resolutions of the Board of Directors authorizing the issuance
          thereof, will be validly issued, fully paid and non-assessable;

       (4)The execution and delivery of this Plan did not, and the consummation
          of the Acquisition will not, violate the Acquiring Fund Charter or
          the Acquiring Fund Bylaws or any agreement of the Acquiring Fund
          known to such counsel, after reasonable inquiry; and

       (5)To the knowledge of such counsel, no consent, approval, authorization
          or order of any federal or state court or administrative or
          regulatory agency, other than the acceptance of record of Articles of
          Transfer by the SDAT, is required for the Acquiring Fund to enter
          into this Plan or carry out its terms, except those that have been
          obtained under the 1933 Act, the 1934 Act, the 1940 Act and the rules
          and regulations under those Acts or that may be required under state
          securities laws or subsequent to the Effective Time or when the
          failure to obtain the consent, approval, authorization or order would
          not have a material adverse effect on the operation of the Acquiring
          Fund.

       In rendering such opinion, Seward & Kissel LLP may (i) rely on the
       opinion of Venable LLP as to matters of Maryland law to the extent set
       forth in such opinion, (ii) make assumptions regarding the authenticity,
       genuineness and/or conformity of documents and copies thereof without
       independent verification thereof, (iii) limit such opinion to applicable
       federal and state law, (iv) define the word "knowledge" and related
       terms to mean the knowledge of attorneys then with such firm who have
       devoted substantive attention to matters directly related to this Plan
       and (v) rely on certificates of officers or directors of the Acquiring
       Fund as to factual matters.

    (b)The Acquired Fund shall have received a letter from the Adviser with
       respect to insurance matters in form and substance satisfactory to the
       Acquired Fund.

          Acquired Fund and, assuming the N-14 Registration Statement referred
          to in Section 2 of this Plan does not contain any material
          misstatements or omissions, and assuming due authorization, execution
          and delivery of this Plan by the Acquiring Fund, represents a legal,

          fraudulent conveyance

                                      58



          and transfer and similar laws relating to or affecting creditors'
          rights generally and court decisions with respect thereto, and
          further subject to the application of equitable principles in any
          proceeding, whether at law or in equity or with respect to the
          enforcement of provisions of the Plan and the effect of judicial
          decisions which have held that certain provisions are unenforceable

       (3)The execution and delivery of this Plan did not, and the consummation
          of the Acquisition will not, violate the Acquired Fund Charter or the

                     TRADING HISTORY AND SHARE PRICE DATA

   Shares of each Fund are traded on the NYSE under the following symbols:
Alliance National Municipal -"AFB" and ACM Municipal Securities - "AMU". Shares
of closed-end management companies frequently trade at discounts from their
NAVs, and the Funds' shares have also traded at a discount in recent times.
Alliance National Municipal has traded at a premium from 02/15/2006 to
10/24/2006. Alliance National Municipal has since traded at a discount ranging
from (3.71)% to (0.19)%. From 05/17/2000 to 11/23/2004, ACM Municipal
Securities traded at a premium. ACM Municipal Securities has since traded at a
discount ranging from (10.27)% to (0.53)%. The following tables set forth for
each Fund's fiscal quarter within the two most recent fiscal years and each
Fund's fiscal quarter since the beginning of the current fiscal year: (a) the
per share high and low sales prices as reported by the NYSE; (b) the NAV per
share, based on the Fund's computation as of 4:00 p.m. on the last NYSE
business day for the week corresponding to the dates on which the respective
high and low prices were recorded; and (c) the discount or premium to NAV
represented by the high and low sales prices shown. The range of NAVs and of
premiums and discounts for the shares during the periods shown may be broader
than is shown in this table. On November 17, 2006, the closing price per share
was $15.28, and $10.63, the NAV per share was $15.58 and $11.43, and the

                                  APPENDIX G

                               LEGAL PROCEEDINGS

   The staff of the U.S. Securities and Exchange Commission ("SEC") and the
Office of the New York Attorney General ("NYAG") have been investigating
practices in the mutual fund industry identified as "market timing" and "late
trading" of mutual fund shares. Certain other regulatory authorities have also
been conducting investigations into these practices within the industry and
have requested that the Adviser provide information to them. The Adviser has
been cooperating and will continue to cooperate with all of these authorities.

   Excluding the occurrences of tender offers or stock repurchases, the shares
of a Fund are not redeemable by a Fund, but are traded on an exchange at prices
established by the market. Accordingly, the Fund and its stockholders are not
subject to the market timing and late trading practices that are the subject of
the investigations mentioned above or the lawsuits described below. Please see
below for a description of the agreements reached by the Adviser and the SEC
and NYAG in connection with the investigations mentioned above.

   Numerous lawsuits have been filed against the Adviser and certain other
defendants in which plaintiffs make claims purportedly based on or related to
the same practices that are the subject of the SEC and NYAG investigations
referred to above. Some of these lawsuits name one or more of the Funds as a
party. The lawsuits are now pending in the United States District Court for the
District of Maryland pursuant to a ruling by the Judicial Panel on
Multidistrict Litigation transferring and centralizing all of the mutual funds
involving market and late trading in the District of Maryland (the "Mutual Fund
MDL"). Management of the Adviser believes that these private lawsuits are not
likely to have a material adverse effect on the results of operations or
financial condition of a Fund.

   On December 18, 2003, the Adviser confirmed that it had reached terms with
the SEC and the NYAG for the resolution of regulatory claims relating to the
practice of "market timing" mutual fund shares in some of the AllianceBernstein
Mutual Funds. The agreement with the SEC is reflected in an Order of the
Commission ("SEC Order"). The agreement with the NYAG is memorialized in an
Assurance of Discontinuation dated September 1, 2004 ("NYAG Order"). Among the
key provisions of these agreements are the following:

    (i)The Adviser agreed to establish a $250 million fund (the "Reimbursement
       Fund") to compensate mutual fund stockholders for the adverse effects of
       market timing attributable to market timing relationships described in
       the SEC Order. According to the SEC Order, the Reimbursement Fund is to
       be paid, in order of priority, to fund investors based on (i) their
       aliquot share of losses suffered by the fund due to market timing, and
       (ii) a proportionate share of advisory fees paid by such fund during the
       period of such market timing;

   (ii)The Adviser agreed to reduce the advisory fees it receives from some of
       the AllianceBernstein long-term, open-end retail funds, commencing
       January 1, 2004, for a period of at least five years; and

  (iii)The Adviser agreed to implement changes to its governance and compliance
       procedures. Additionally, the SEC Order contemplates that the Adviser's
       registered investment company clients, including the Fund, will
       introduce governance and compliance changes.

   The shares of a Fund are not redeemable by a Fund, but are traded on an
exchange at prices established by the market. Accordingly, a Fund and its
stockholders are not subject to the market timing practices described in the
SEC Order and are not expected to participate in the Reimbursement Fund. Since
the Funds are closed-end funds, they will not have their advisory fee reduced
pursuant to the terms of the agreements mentioned above.

   On February 10, 2004, the Adviser received (i) a subpoena duces tecum from
the Office of the Attorney General of the State of West Virginia and (ii) a
request for information from West Virginia's Office of the State Auditor,
Securities Commission (the "West Virginia Securities Commission") (together,
the "Information Requests"). Both Information Requests require the Adviser to
produce documents concerning, among other things, any market timing or late
trading in the Adviser's sponsored mutual funds. The Adviser responded to the
Information Requests and has been cooperating fully with the investigation.

                                      66



   On April 11, 2005, a complaint entitled The Attorney General of the State of
West Virginia v. AIM Advisors, Inc., et al. ("WVAG Complaint") was filed
against the Adviser, Alliance Capital Management Holding L.P. ("Alliance
Holding"), and various other defendants not affiliated with the Adviser. The
WVAG Complaint was filed in the Circuit Court of Marshall County, West Virginia
by the Attorney General of the State of West Virginia. The WVAG Complaint makes
factual allegations generally similar to those in certain of the complaints
related to the lawsuits discussed above. On May 31, 2005, defendants removed
the WVAG Complaint to the United States District Court for the Northern
District of West Virginia. On July 12, 2005, plaintiff moved to remand. On
October 19, 2005, the WVAG Complaint was transferred to the Mutual fund MDL.

   On August 30, 2005, the deputy commissioner of securities of the West
Virginia Securities Commission signed a "Summary Order to Cease and Desist, and
Notice of Right to Hearing" addressed to the Adviser and Alliance Holding. The
Summary Order claims that the Adviser and Alliance Holding violated the West
Virginia Uniform Securities Act, and makes factual allegations generally
similar to those in the SEC Order and the NYAG Order. On January 26, 2006, the
Adviser, Alliance Holding, and various unaffiliated defendants filed a Petition
for Writ of Prohibition and Order Suspending Proceedings in West Virginia state
court seeking to vacate the Summary Order and for other relief. The Adviser
intends to vigorously defend against the allegations in the WVAG Complaint.

   On June 22, 2004, a purported class action complaint entitled Aucoin, et al.
v. Alliance Capital Management L.P., et al. ("Aucoin Complaint") was filed
against the Adviser, Alliance Capital Management Holding L.P., Alliance Capital
Management Corporation, AXA Financial, Inc., AllianceBernstein Investment
Research & Management, Inc., certain current and former directors of the
AllianceBernstein Mutual Funds, and unnamed Doe defendants. The Aucoin
Complaint names certain of the AllianceBernstein mutual funds as nominal
defendants. The Funds were not named as defendants in the Aucoin Complaint. The
Aucoin Complaint was filed in the United States District Court for the Southern
District of New York by an alleged stockholder of an AllianceBernstein mutual
fund. The Aucoin Complaint alleges, among other things, (i) that certain of the
defendants improperly authorized the payment of excessive commissions and other
fees from fund assets to broker-dealers in exchange for preferential marketing
services, (ii) that certain of the defendants misrepresented and omitted from
registration statements and other reports material facts concerning such
payments, and (iii) that certain defendants caused such conduct as control
persons of other defendants. The Aucoin Complaint asserts claims for violation
of Sections 34(b), 36(b) and 48(a) of the Investment Company Act, Sections 206
and 215 of the Advisers Act, breach of common law fiduciary duties, and aiding
and abetting breaches of common law fiduciary duties. Plaintiffs seek an
unspecified amount of compensatory damages and punitive damages, rescission of
their contracts with the Adviser, including recovery of all fees paid to the
Adviser pursuant to such contracts, an accounting of all fund-related fees,
commissions and soft dollar payments, and restitution of all unlawfully or
discriminatorily obtained fees and expenses.

   Since June 22, 2004, nine additional lawsuits making factual allegations
substantially similar to those in the Aucoin Complaint were filed against the
Adviser and certain other defendants. All nine of the lawsuits (i) were brought
as class actions filed in the United States District Court for the Southern
District of New York, (ii) assert claims substantially identical to the Aucoin
Complaint, and (iii) are brought on behalf of stockholders of the Funds.

   On February 2, 2005, plaintiffs filed a consolidated amended class action
complaint ("Aucoin Consolidated Amended Complaint") that asserts claims
substantially similar to the Aucoin Complaint and the nine additional lawsuits
referenced above. On October 19, 2005, the District Court dismissed each of the
claims set forth in the Aucoin Consolidated Amended Complaint, except for
plaintiff's claim under Section 36(b) of the Investment Company Act. On
January 11, 2006, the District Court granted defendants' motion for
reconsideration and dismissed the remaining Section 36(b) claim. Plaintiffs
have moved for leave to amend their consolidated complaint.

                                      67



   On October 19, 2005, the District Court granted in part, and denied in part,
defendants' motion to dismiss the Aucoin Complaint and as a result the only
claim remaining is plaintiffs' Section 36(b).

   On August 7, 2006, the Mutual Fund MDL signed an Order staying the actions
(including discovery) against the Alliance defendants pending settlement.

   The Adviser believes that these matters are not likely to have a material
adverse effect on the Funds or the Adviser's ability to perform advisory
services relating to the Funds.

                                      68

                          FINANCIAL HIGHLIGHTS TABLE

   The financial highlights table is intended to help you understand a Fund's
financial performance for the past 5 years (or since inception of the Fund).
Certain information reflects financial results for a single share of a Fund.
The total returns in the table represent the rate that an investor would have
earned (or lost) on an investment in a Fund (assuming reinvestment of all
dividends and distributions). This information (as noted below) has been
audited by Ernst & Young LLP, the independent registered public accounting firm
for a Fund, whose reports, along with the Fund's financial statements, are
included in the Fund's annual report, which is available upon request.

(a)As of November 1, 2003, the Fund has adopted the method of accounting for
   interim payments on swap contracts in accordance with Financial Accounting
   Standards Board Statement No. 133. These interim payments are reflected
   within net realized and unrealized gain (loss) on swap contracts, however,
   prior to November 1, 2003, these interim payments were reflected within
   interest income/expense on the statement of operations. For the year ended
   October 31, 2004, the effect of this change to the net investment income and
   the net realized and unrealized gain (loss) on investment transactions was
   less than $0.01 per share and the ratio of net investment income to average
   net assets was .00%.

                                      71



(b)Commencement of operations. Net asset value immediately after the closing of
   the first public offering was $14.30.
(c)Based on average shares outstanding.
(d)Net of fees waived by the Adviser.
(e)Total investment return is calculated assuming a purchase of common stock on
   the opening of the first day and a sale on the closing of the last day of
   the period reported. Dividends and distributions, if any, are assumed for
   purposes of this calculation, to be reinvested at prices obtained under the
   Fund's dividend reinvestment plan. Generally, total investment return based
   on net asset value will be higher than total investment return based on
   market value in periods where there is an increase in the discount or a
   decrease in the premium of the market value to net asset value from the
   beginning to the end of such periods. Conversely, total investment return
   based on net asset value will be lower than total investment return based on
   market value in periods where there is a decrease in the discount or an
   increase in the premium of the market value to the net asset value from the
   beginning to the end of the period. Total investment return calculated for a
   period of less than one year is not annualized.
(f)These expense and net investment income ratios do not reflect the effect of
   dividend payments to preferred shareholders.
(g)Annualized.

(a)As of November 1, 2003, the Fund has adopted the method of accounting for

   within net realized and unrealized gain (loss) on swap

                                      73



   contracts, however, prior to November 1, 2003, these interim payments were
   reflected within interest income/expense on the statement of operations. For
   the year ended October 31, 2004, the effect of this change to the net
   investment income and the net realized and unrealized gain (loss) on
   investment transactions was less than $0.01 per share and the ratio of net
   investment income to average net assets was less than .01%.
(b)Total investment return is calculated assuming a purchase of common stock on
   the opening of the first day and a sale on the closing of the last day of
   each period reported. Dividends and distributions, if any, are assumed for
   purposes of this calculation, to be reinvested at prices obtained under the
   Fund's dividend reinvestment plan. Generally, total investment return based
   on net asset value will be higher than total investment return based on
   market value in periods where there is an increase in the discount or a
   decrease in the premium of the market value to net asset value from the
   beginning to the end of such periods. Conversely, total investment return

   market value in periods where there is a decrease in the discount or an
   increase in the premium of the market value to the net asset value from the
   beginning to the end of the period. Total investment returns for periods of
   less than one full year are not annualized.
(c)These expense and net investment income ratios do not reflect the effect of
   dividend payments to preferred shareholders.
(d)Net of fee waiver. If the Administrator had not waived expenses, the ratios
   to average net assets applicable to common shareholders for expenses, net
   investment income before preferred stock dividends and net investment income
   net of preferred stock dividends would have been 1.61%, 7.19% and 5.03%,
   respectively, for the six months ended April 30, 2006.

     The following supplements the information contained in the Prospectus/Proxy
Statement concerning the Funds. Alliance National Municipal and ACM Municipal
Securities are each diversified closed-end investment companies registered under
the Investment Company Act of 1940, as amended (the "1940 Act").

                       INVESTMENT OBJECTIVES AND POLICIES

     GENERAL. The investment objective of both Alliance National Municipal and
ACM Municipal Securities is to seek to provide high current income exempt from
regular federal income tax. In seeking to achieve its investment objective,
Alliance National Municipal invests, under normal market conditions, at least
80%, and normally substantially all, of its net assets in municipal bonds (as
defined below) paying interest that is exempt from regular federal income tax.
ACM Municipal Securities invests, under normal market conditions, at least 80%
of its total assets in municipal securities. Alliance National Municipal will
normally invest at least 75% of its net assets and ACM Municipal Securities will
invest substantially all of its assets in investment-grade municipal bonds (and,
in the case of Alliance National Municipal, also unrated municipal bonds
considered to be of comparable quality by the Adviser). ACM Municipal Securities
may invest up to 20% of its total assets in unrated municipal securities that
are determined to be of equivalent credit quality by the Adviser. Alliance
National Municipal may invest up to 25% of its net assets in municipal bonds
rated below investment grade and unrated municipal bonds considered to be of
comparable quality by the Adviser. The Funds may also invest in municipal notes
(as defined below) and may buy and sell futures contracts on municipal
securities or U.S. Government Securities (as defined below). The Funds are
designed primarily for long term investment and investors should not consider
any Fund to be a short-term trading vehicle. As with all investment companies,
there can be no assurance that a Fund's objective will be achieved.

     Alliance National Municipal has adopted a fundamental policy that it will
invest at least 80% of its net assets in municipal bonds. ACM Municipal
Securities has a fundamental policy that it will invest at least 80% of its
total assets in municipal securities. Each Fund's investment objective and
fundamental policy (and its investment restrictions set forth below under
"Investment Restrictions") may be changed only with the approval of the holders
of a "majority of the Fund's outstanding voting securities," (whether voting
together as a single series or voting as a separate series) which means the
lesser of (i) 67% of the shares of the Fund represented at a meeting at which
more than 50% of the outstanding shares are present in person or represented by
proxy, or (ii) more than 50% of the outstanding shares. Each Fund's other
investment policies described below, except as set forth under "Investment
Restrictions," are not fundamental and may be changed by the Fund without
stockholder approval, but the Fund will not change its investment policies
without contemporaneous notice to its stockholders.

     MUNICIPAL BONDS. Municipal bonds are typically classified as either general
obligation or revenue (or special tax) bonds and are typically issued to finance
public projects (such as roads or public buildings), to pay general operating
expenses, or to refinance outstanding debt. Municipal bonds may also be issued
for private activities, such as housing, medical and educational facility
construction, or for privately owned industrial development and pollution
control projects. General obligation bonds are backed by the full faith and
credit, or taxing authority, of the issuer and may be repaid from any revenue
source; revenue bonds may be repaid only from the revenues of a specific
facility or source. The Funds also may purchase municipal bonds that represent
lease obligations. (However, ACM Municipal Securities will not invest more than
5% of its assets in municipal lease obligations that contain non-appropriation
clauses.) These carry special risks because the issuer of the bonds may not be
obligated to appropriate money annually to make payments under the lease. In
order to reduce this risk, a Fund will only purchase municipal bonds
representing lease obligations when the Adviser believes the issuer has a strong
incentive to continue making appropriations until maturity.

     The yields on municipal bonds depend on a variety of factors, including
prevailing interest rates and the condition of the general money market and the
municipal bond market, the size of a particular offering, the maturity of the
obligation and the rating of the issue. The market value of municipal bonds will
vary with changes in interest rate levels and as a result of changing
evaluations of the ability of their issuers to meet interest and principal
payments.

     Alliance National Municipal will invest primarily in municipal bonds with
long-term maturities in order to maintain a weighted average maturity of 15-30
years, but the weighted average maturity of obligations held by the Fund may be
shortened, depending on market conditions. ACM Municipal Securities expects that
the dollar-weighted average maturity of its investments will be approximately
15-20 years.

     MUNICIPAL SECURITIES. Municipal Securities are issued to obtain funds for
various public purposes, including the construction and maintenance of such
public facilities as airports, bridges, highways, housing, hospitals, mass
transportation, schools, streets and water and sewer works. Other public
purposes for which Municipal Securities may be issued include the refinancing of
outstanding obligations and the obtaining of funds for general operating
expenses and for loans to other public institutions and facilities. In addition,
certain industrial development, private activity and pollution control bonds may
be considered to be Municipal Securities if the interest paid thereon qualifies
as exempt from regular federal income tax. Both Funds intend to invest primarily
in municipal bonds that pay interest that is not subject to the alternative
minimum tax ("AMT"), but may invest without limit in municipal bonds that pay
interest that is subject to the AMT.

     Municipal Securities have two principal classifications: "general
obligation" bonds and "revenue" or "special obligation" bonds. General
obligation bonds are secured by the issuer's pledge of its full faith, credit
and taxing power for the payment of principal and interest. Revenue or special
obligation bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special excise tax or other specific revenue source but not from general tax or
other unrestricted revenues of the issuer. Private activity, industrial
development and pollution control bonds are in most cases revenue bonds and do
not generally constitute the pledge of the credit or taxing power of the issuer
of such bonds. The payment of the principal and interest on such revenue bonds
depends solely on the ability of the user of the facilities financed by the
bonds to meet its financial obligations and the pledge, if any, of real and
personal property so financed as security for such payment. There are, of
course, variations in the security of Municipal Securities, both within a
particular classification and between classifications, depending on numerous
factors.

     Also included within the general category of Municipal Securities are
certain lease obligations or installment purchase contract obligations and
participations therein (hereinafter collectively called "Municipal Lease
Obligations") of municipal authorities or entities. Although Municipal Lease
Obligations do not constitute general obligations of the municipality for which
the municipality's taxing power is pledged, a Municipal Lease Obligation is
ordinarily backed by the municipality's covenant to budget for, appropriate and
make the payments due under the lease obligation. Interest on Municipal Lease
Obligations is tax-exempt to the same extent as if the municipality had issued
debt obligations to finance the underlying project or purchase. However, certain
Municipal Lease Obligations contain "non-appropriation" clauses which provide
that the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. Although "non-appropriation" lease obligations are generally
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. In addition, the tax treatment of such
obligations in the event of non-appropriation is unclear. ACM Municipal
Securities will seek to minimize these risks by not investing more that 5% of
its total investment assets in Municipal Lease Obligations that contain
"non-appropriation" clauses.

     The Funds may invest a portion of their assets in Municipal Securities that
pay interest at a coupon rate equal to a base rate plus additional interest for
a certain period of time if short-term interest rates rise above a predetermined
level or "cap." Although the specific terms of these Municipal Securities may
differ, the amount of any additional interest payment typically is calculated
pursuant to a formula based upon an applicable short-term interest rate index
multiplied by a designated factor. This use of a designated factor in the
calculation of additional interest effectively multiplies the underlying
principal amount of these Municipal Securities, and will enable a Fund to
purchase a sufficient amount of these securities so that the "notional
principal" on which any additional interest is calculated is equal to at least
100% of the liquidation preference of any preferred stock that a Fund may issue.
The Adviser believes that during periods of sharp increases in short-term
interest rates, the total coupon rate payable on these Municipal Securities
frequently would exceed prevailing short-term interest rates. The additional
interest component of the coupon rate of these Municipal Securities generally
expires before the maturity of the underlying instrument. These Municipal
Securities may also contain provisions that provide for conversion at the option
of the issuer to constant interest rates in addition to standard call features.

     Municipal Securities may have fixed, variable, or floating rates of
interest. Variable and floating rate securities pay interest at rates that are
adjusted periodically, according to a specified formula, in order to minimize
fluctuation in the principal value of the securities. A "variable" interest rate
adjusts at predetermined intervals (e.g., daily, weekly, or monthly), while a
"floating" interest rate adjusts whenever a specified benchmark rate (e.g., bank
prime lending rate) changes.

     Other Municipal Securities are zero coupon securities, which are debt
obligations that do not entitle the holder to any periodic payments prior to
maturity and are issued and traded at a discount from their face amounts. The
discount varies depending on the time remaining until maturity, prevailing
interest rates, liquidity of the security, and perceived credit quality of the
issuer. The market prices of zero coupon securities are generally more volatile
than the market prices of securities that pay interest periodically and are
likely to respond to changes in interest rates to a greater degree than do
securities having similar maturities and credit quality that do pay periodic
interest.

     Zero coupon Municipal Securities may be created by investment banks under
proprietary programs in which they strip the interest component from the
principal component and sell both separately in the form of custodial receipts
or certificates underwritten by securities dealers or banks that evidence
ownership of future interest payments, principal payments, or both on certain
Municipal Securities. ACM Municipal Securities may invest up to 10% of its total
assets in such custodial receipts or certificates underwritten by securities
dealers or banks. The underwriter of these certificates or receipts typically
purchases Municipal Securities and deposits the obligations in an irrevocable
trust or custodial account with a custodian bank, which then issues receipts or
certificates that evidence ownership of the periodic unmatured coupon payments
and the final principal payment on the obligations. Custodial receipts
evidencing specific coupon or principal payments have the same general
attributes as zero coupon Municipal Securities described above. Although under
the terms of a custodial receipt, ACM Municipal Securities typically would be
authorized to assert its rights directly against the issuer of the underlying
obligations, ACM Municipal Securities could be required to assert through the
custodian bank those rights as may exist against the underlying issuer. Thus, in
the event the underlying issuer fails to pay principal and/or interest when due,
ACM Municipal Securities may be subject to delays, expenses, and risks that are
greater than those that would have been involved if ACM Municipal Securities had
purchased a direct obligation of the issuer. In addition, in the event that the
trust or custodial account in which the underlying security has been deposited
is determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.

     ACM Municipal Securities may also invest in Municipal Securities, the
interest rate on which has been divided into two different and variable
components, which together result in a fixed interest rate. Typically, the first
of the components (the "Auction Component") pays an interest rate that is reset
periodically through an auction process, whereas the second of the components
(the "Residual Component") pays a current residual interest rate based on the
difference between the total interest paid by the issuer on the Municipal
Security and the auction rate paid on the Auction Component. ACM Municipal
Securities may purchase both Auction and Residual Components. If ACM Municipal
Securities issues shares of preferred stock, the Fund will limit its investment
in Residual Components to no more than 10% of its total assets.

     Because the interest rate paid to holders of Residual Components is
generally determined by subtracting the interest rate paid to the holders of
Auction Components from a fixed amount, the interest rate paid to Residual
Component holders will decrease as the Auction Component's rate increases and
increase as the Auction Component's rate decreases. Moreover, the extent of the
increases and decreases in market value of Residual Components may be larger
than comparable changes in the market value of an equal principal amount of a
fixed rate Municipal Security having similar credit quality, redemption
provisions, and maturity.

     Although the Funds intend to invest a substantial portion of their assets
in longer term Municipal Securities, Municipal Securities in which the Funds may
invest include municipal notes, which may be either "general obligation" or
"revenue" securities, are intended to fulfill short-term capital needs and
generally have original maturities not exceeding one year.

     Municipal notes in which the Funds may invest include demand notes, which
are tax-exempt obligations that have stated maturities in excess of one year,
but permit the holder to sell back the security (at par) to the issuer within 1
to 7 days notice. The payment of principal and interest by the issuer of these
obligations will ordinarily be guaranteed by letters of credit offered by banks.
The interest rate on a demand note may be based upon a known lending rate, such
as a bank's prime rate, and may be adjusted when such rate changes, or the
interest rate on a demand note may be a market rate that is adjusted at
specified intervals.

     Other short-term obligations constituting municipal notes include tax
anticipation notes, revenue anticipation notes, and bond anticipation notes, and
tax-exempt commercial paper.

     Tax anticipation notes are issued to finance working capital needs of
municipalities. Generally, they are issued in anticipation of various seasonal
tax revenues, such as income, sales, use, and business taxes. Revenue
anticipation notes are issued in expectation of receipt of other types of
revenues, such as federal revenues available under the Federal Revenue Sharing
Programs. Bond anticipation notes are issued to provide interim financing until
long-term financing can be arranged. In most such cases, the long-term bonds
provide the money for the repayment of the notes.

     Tax-exempt commercial paper is a short-term obligation with a stated
maturity of 365 days or less (however, issuers typically do not issue such
obligations with maturities longer than seven days). Such obligations are issued
by state and local municipalities to finance seasonal working capital needs or
as short-term financing in anticipation of longer-term financing.

     Yields on Municipal Securities are dependent on a variety of factors,
including the general conditions of the municipal securities market, the size of
a particular offering, the maturity of the obligation and the rating of the
issue. Municipal Securities with longer maturities tend to produce higher yields
and are generally subject to greater price movements than obligations with
shorter maturities. An increase in interest rates generally will reduce the
market value of portfolio investments, and a decline in interest rates generally
will increase the value of portfolio investments. The achievement of a Fund's
investment objectives depends in part on the continuing ability of the issuers
of Municipal Securities in which a Fund invests to meet their obligations for
the payment of principal and interest when due. Municipal Securities
historically have not been subject to registration with the Securities and
Exchange Commission, although, from time to time, there have been proposals that
would require registration in the future.

     Obligations of issuers of Municipal Securities are subject to the
provisions of bankruptcy, insolvency, and other laws affecting the rights and
remedies of creditors, such as the Federal Bankruptcy Code. In addition, the
obligations of such issuers may become subject to laws enacted in the future by
Congress, state legislatures, or referenda extending the time for payment of
principal and/or interest, or imposing other constraints upon enforcement of
such obligations or upon the ability of municipalities to levy taxes. There is
also the possibility that, as a result of litigation or other conditions, the
ability of any issuer to pay, when due, the principal or the interest on its
municipal bonds may be materially affected. See "Risk Factors and Special
Considerations."

     U.S. GOVERNMENT SECURITIES. Securities issued or guaranteed by the United
States Government, its agencies or instrumentalities include: (i) U.S. Treasury
obligations, which differ only in their interest rates, maturities and times of
issuance, U.S. Treasury bills (maturity of one year or less), U.S. Treasury
notes (maturities of one to 10 years), and U.S. Treasury bonds (generally
maturities of greater than 10 years), all of which are backed by the full faith
and credit of the United States, and (ii) obligations issued or guaranteed by
U.S. Government agencies or instrumentalities, including government guaranteed
mortgage-related securities, some of which are backed by the full faith and
credit of the U.S. Treasury (e.g., direct pass-through certificates of the
Government National Mortgage Association), some of which are supported by the
right of the issuer to borrow from the U.S. Government (e.g., obligations of
Federal Home Loan Banks), and some of which are backed only by the credit of the
issuer itself (e.g., obligations of the Student Loan Marketing Association).

     General. U.S. Government Securities do not generally involve the credit
risks associated with other types of interest-bearing securities although, as a
result, the yields available from U.S Government Securities are generally lower
than the yields available from other interest-bearing securities. Like other
fixed-income securities, however, the values of U.S. Government Securities
change as interest rates fluctuate. When interest rates decline, the values of
U.S. Government Securities can be expected to increase and when interest rates
rise, the values of U.S. Government Securities can be expected to decrease.

     Government Guaranteed Mortgage-Related Securities--General. Mortgages
backing the securities purchased by a Fund include, among others, conventional
thirty-year fixed rate mortgages, graduated payment mortgages, fifteen-year
mortgages and adjustable rate mortgages. All of these mortgages can be used to
create pass-through securities. A pass-through security is formed when mortgages
are pooled together and undivided interests in the pool or pools are sold. The
cash flow from the mortgages is passed through to the holders of the securities
in the form of periodic payments of interest, principal and prepayments (net of
a service fee). Prepayments occur when the holder of an individual mortgage
prepays the remaining principal before the mortgages scheduled maturity date. As
a result of the pass-through of prepayments of principal on the underlying
securities, mortgage-backed securities are often subject to more rapid
prepayment of principal than their stated maturity would indicate. Because the
prepayment characteristics of the underlying mortgages vary, it is not possible
to predict accurately the realized yield or average life of a particular issue
of pass-through certificates. Prepayment rates are important because of their
effect on the yield and price of the securities. Accelerated prepayments
adversely impact the yields for pass-through securities purchased at a premium
(i.e., a price in excess of principal amount) and may involve additional risk of
loss of principal because the premium may not have been fully amortized at the
time the obligation is repaid. The opposite is true for pass-through securities
purchased at a discount. A Fund may purchase mortgage-related securities at a
premium or at a discount. Principal and interest payments on the
mortgage-related securities are government guaranteed to the extent described
below. Such guarantees do not extend to the value or yield of the
mortgage-related securities themselves or of a Fund's shares of common stock.

     GNMA Certificates. Certificates of the Government National Mortgage
Association ("GNMA Certificates") are mortgage-backed securities, which evidence
an undivided interest in a pool or pools of mortgages. GNMA Certificates that a
Fund purchases are the "modified pass-through" type, which entitle the holder to
receive timely payment of all interest and principal payments due on the
mortgage pool, net of fees paid to the "issuer" and GNMA, regardless of whether
or not the mortgagor actually makes the payment.

     The National Housing Act authorizes GNMA to guarantee the timely payment of
principal and interest in securities backed by a pool of mortgages insured by
the Federal Housing Administration ("FHA") or guaranteed by the Veterans
Administration ("VA"). The GNMA guarantee is backed by the full faith and credit
of the United States. The GNMA is also empowered to borrow without limitation
from the U.S. Treasury, if necessary, to make any payments required under its
guarantee.

     The average life of a GNMA Certificate is likely to be substantially
shorter than the original maturity of the mortgages underlying the securities.
Prepayments of principal by mortgagors and mortgage foreclosures will usually
result in the return of the greater part of principal investment long before the
maturity of the mortgages in the pool. Foreclosures impose no risk to principal
investment because of the GNMA guarantee, except to the extent that a Fund has
purchased the certificates above par in the secondary market.

     FHLMC Securities. The Federal Home Loan Mortgage Corporation ("FHLMC") was
created in 1970 through the enactment of Title III of the Emergency Home Finance
Act of 1970. Its purpose is to promote development of a nationwide secondary
market in conventional residential mortgages.

     The FHLMC issues two types of mortgage pass-through securities ("FHLMC
Certificates"), mortgage participation certificates ("PCs") and guaranteed
mortgage certificates ("GMCs"). PCs resemble GNMA Certificates in that each PC
represents a pro rata share of all interest and principal payments made and owed
on the underlying pool. The FHMLC guarantees timely monthly payment of interest
on PCs and the ultimate payment of principal.

     GMCs also represent a pro rata interest in a pool of mortgages. However,
these instruments pay interest semi-annually and return principal once a year in
guaranteed minimum payments. The expected average life of these securities is
approximately ten years. The FHLMC guarantee is not backed by the full faith and
credit of the United States.

     FNMA Securities. The Federal National Mortgage Association ("FNMA") was
established in 1938 to create a secondary market in mortgages insured by the
FHA.

     FNMA issues guaranteed mortgage pass-through certificates ("FNMA
Certificates"). FNMA Certificates resemble GNMA Certificates in that each FNMA
Certificate represents a pro rata share of all interest and principal payments
made and owed on the underlying pool. FNMA guarantees timely payment of interest
and principal on FNMA Certificates. The FNMA guarantee is not backed by the full
faith and credit of the United States.

     OTHER SECURITIES. While the principal investment strategies of Alliance
National Municipal and ACM Municipal Securities emphasize investment in
municipal securities, a Fund may, where consistent with its investment
objective, invest in securities other than Municipal Securities, including (i)
futures contracts and options on futures contracts on Municipal Securities or
U.S. Government Securities; and (ii) repurchase agreements pertaining to U.S.
Government Securities.

     ACM Municipal Securities may invest in high-quality municipal notes rated
SP-2 or higher by Standard & Poor's ("S&P") or MIG 2 (or VMIG 2) or higher by
Moody's Investor Service ("Moody's) or rated of equivalent credit quality by any
other nationally recognized statistical rating organization ("NRSRO"), or in
taxable cash equivalents, including: (i) U.S. Government Securities, (ii)
certificates of deposit, banker's acceptances, and interest-bearing savings
deposits of banks having total assets of more than $1 billion and which are
members of the Federal Deposit Insurance Corporation, (iii) commercial paper of
prime quality rated A-1 or higher by S&P, Prime-1 or higher by Moody's, or rated
of equivalent credit quality by any other NRSRO or, if not rated, issued by
companies that have an outstanding debt rated AA or higher by S&P or Aa or
higher by Moody's or rated of equivalent credit quality by any other NRSRO, and
(iv) repurchase agreements pertaining to U.S. Government Securities. ACM
Municipal Securities will not be required to dispose of a Municipal Security
that is downgraded below BBB or Baa, or, if unrated, determined by the Adviser
to have undergone similar credit quality deterioration, subsequent to purchase
by the Fund, although the Adviser will monitor the creditworthiness of such
securities and dispose of them as it deems appropriate. ACM Municipal Securities
expects that no more than 5%, if any, of its total assets will consist of
Municipal Securities whose ratings have been downgraded below BBB or Baa or, if
unrated, determined by the Adviser to have undergone similar credit quality
deterioration. See Appendix A for a general description of S&P's and Moody's
securities ratings.

     ACM Municipal Securities has not established any limit on the percentage of
its portfolio that may be invested in Municipal Securities the interest on which
is subject to the alternative minimum tax provisions of federal income tax law
("AMT Municipal Securities"), and a substantial portion of the income produced
by ACM Municipal Securities may be includable in the calculation of alternative
minimum taxable income. Shares of ACM Municipal Securities' common stock,
therefore, generally will not be a suitable investment for investors who are
subject to the federal alternative minimum tax. The suitability of shares of ACM
Municipal Securities' common stock for investors will depend upon a comparison
of the after-tax yield likely to be provided from the Fund with that from
comparable tax-exempt investment not subject to the federal alternative minimum
tax, and from comparable fully taxable investments, in light of each such
investor's tax position. Special considerations apply to corporate investors.
See "Taxation - Alternative Minimum Tax."

     The Funds may utilize certain futures, options, interest rate swaps, and
related transactions for hedging purposes. To the extent a Fund generates
taxable income by utilizing such hedging practices or investing in taxable
securities, a Fund's ability to achieve its investment objective of providing
high current income exempt from regular federal income tax may be limited.

INVESTMENT PRACTICES

     Options on U.S. Government Securities. In an effort to increase current
income and to reduce fluctuations in net asset value ("NAV"), ACM Municipal
Securities intends to write covered put and call options and purchase put and
call options on Municipal Securities and U.S. Government Securities of the types
in which it is permitted to invest that are traded on U.S. exchanges. ACM
Municipal Securities also intends to write call options for cross-hedging
purposes. There are no specific limitations on the Funds' writing and purchasing
of options.

     A put option gives the purchaser of such option, upon payment of a premium,
the right to deliver a specified amount of a security to the writer of the
option on or before a fixed date at a predetermined price. A call option gives
the purchaser of the option, upon payment of a premium, the right to call upon
the writer to deliver a specified amount of a security on or before a fixed date
at a predetermined price. A call option written by a Fund is "covered" if a Fund
owns the underlying security covered by the call or has an absolute and
immediate right to acquire that security without additional cash consideration
(or for additional cash consideration held in a segregated account by its
Custodian) upon conversion or exchange of other securities held in its
portfolio. A call option is also covered if a Fund holds a call on the same
security in the same principal amount as the call written and the exercise price
of the call held (a) is equal to or less than the exercise price of the call or
(b) is greater than the exercise price of the call written and the difference is
maintained by a Fund in cash and liquid high-grade debt securities in a
segregated account with its Custodian. A put option written by a Fund is
"covered" if a Fund maintains cash not available for investment or liquid
high-grade debt securities with a value equal to the exercise price in a
segregated amount with its Custodian, or else holds a put on the same security
in the same principal amount as the put written and the exercise price of the
put held is equal to or greater than the exercise price of the put written. The
premium paid by the purchaser of an option reflects, among other things, the
relationship of the exercise price to the market price and volatility of the
underlying security, the remaining term of the option, supply and demand and
interest rates.

     A call option is written for cross-hedging purposes if a Fund does not own
the underlying security but seeks to provide a hedge against a decline in value
in another security which a Fund owns or has the right to acquire. In such
circumstances, a Fund collateralizes the option by maintaining in a segregated
account with its Custodian cash or liquid U.S. Government Securities in an
amount not less than the market value of the underlying security, marked to
market daily. A Fund would write a call option for cross-hedging purposes,
instead of writing a covered call option, when the premium to be received from
the cross-hedge transaction would exceed that which would be received from
writing a covered call option, while at the same time achieving the desired
hedge.

     In purchasing a call option, a Fund would be in a position to realize a
gain if, during the option period, the price of the underlying security
increased by an amount in excess of the premium paid. It would realize a loss if
the price of the underlying security declined or remained the same or did not
increase during the period by more than the amount of the premium. In purchasing
a put option, a Fund would be in a position to realize a gain if, during the
option period, the price of the underlying security declined by an amount in
excess of the premium paid. It would realize a loss if the price of the
underlying security increased or remained the same or did not decrease during
that period by more than the amount of the premium. If a put or call option
purchased by a Fund were permitted to expire without being sold or exercised,
the Fund would lose the premium.

     If a put option written by a Fund were exercised, a Fund would be obligated
to purchase the underlying security at the exercise price. If a call option
written by a Fund were exercised, a Fund would be obligated to sell the
underlying security at the exercise price. The risk involved in writing a put
option is that there could be a decrease in the market value of the underlying
security caused by rising interest rates or other factors. If this occurred, the
option could be exercised and the underlying security would then be sold by the
option holder to a Fund at a higher price than its current market value. The
risk involved in writing a call option is that there could be an increase in the
market value or the underlying security caused by declining interest rates or
other factors. If this occurred, the option could be exercised and the
underlying security would then be sold by a Fund at a lower price than its
current market value. These risks could be reduced by entering into a closing
transaction. A Fund retains the premium received from writing a put or call
option whether or not the option is exercised.

     A Fund may purchase or write options on securities of the types in which it
is permitted to invest in privately negotiated transactions. A Fund will effect
such transactions only with investment dealers and other financial institutions
(such as commercial banks or savings and loan institutions) deemed creditworthy
by the Adviser, and the Adviser has adopted procedures for monitoring the
creditworthiness of such entities. Options purchased or written by a Fund in
negotiated transactions are illiquid and it may not be possible for a Fund to
effect a closing transaction at a time when the Adviser believes it would be
advantageous to do so. See "Risk Factors and Special Considerations - General
Risks of Investing in the Funds - Securities Not Readily Marketable."

     Zero Coupon Treasury Securities. The Funds may invest in Zero Coupon
Treasury securities. Currently the only U.S. Treasury security issued without
coupons is the Treasury bill. Although the U.S. Treasury does not itself issue
Treasury notes and bonds without coupons, under the U.S. Treasury STRIPS program
interest and principal payments on certain long term Treasury securities may be
maintained separately in the Federal Reserve book entry system and may be
separately traded and owned. In addition, in the last few years a number of
banks and brokerage firms have separated ("stripped") the principal portions
("corpus") from the coupon portions of U.S. Treasury bonds and notes and hold
them separately in the form of receipts or certificates representing undivided
interests in these instruments (which instruments are generally held by a bank
in a custodial or trust account). The staff of the Securities and Exchange
Commission ("SEC") has indicated, that, in its view these receipts or
certificates should be considered as securities issued by the bank or brokerage
firm involved and, therefore, should not be included in a Fund's categorization
of U.S. Government Securities. The Funds disagree with the staff's
interpretation but have undertaken that they will not invest in such securities
until final resolution of the issue. However, if such securities are deemed to
be U.S. Government Securities, a Fund will not be subject to any limitations on
their purchase.

     Zero Coupon Treasury securities do not entitle the holder to any periodic
payments of interest prior to maturity. Accordingly, such securities usually
trade at a deep discount from their face or par value and will be subject to
greater fluctuations of market value in response to changing interest rates than
debt obligations of comparable maturity which make current distributions of
interest. Current federal tax law requires that a holder (such as a Fund) of a
zero coupon security accrue a portion of the discount at which the security was
purchased as income each year even though a Fund receives no interest payment in
cash on the security during the year.

     Zero Coupon Bonds. Zero Coupons Bonds are debt securities that have been
issued without interest coupons or stripped of their unmatured interest coupons,
and include receipts or certificates representing interests in such securities.
Such a security pays no interest to its holder during its life. Its value to an
investor consists of the difference between its face value at the time of
maturity and the price for which it was acquired, which is generally an amount
significantly less than its face value. Even though the Funds do not receive any
interest on zero coupon bonds during their life, they nonetheless accrue income
with respect to such bonds and thus may have to dispose of portfolio securities
under disadvantageous circumstances in order to obtain cash needed to pay
dividends in amounts necessary to avoid unfavorable tax consequences. Zero
coupon bonds usually trade at a deep discount from their face or par value and
are subject to greater fluctuations in market value in response to changing
interest rates than debt obligations of comparable maturities and credit quality
that make current distributions of interest. On the other hand, because there
are no periodic interest payments to be reinvested prior to maturity, these
securities eliminate reinvestment risk and "lock in" a rate of return to
maturity.

     Futures Contracts and Options on Futures Contracts. Both Alliance National
Municipal and ACM Municipal Securities may enter into contracts for the purchase
or sale for future delivery of Municipal Securities or U.S. Government
Securities, or contracts based on financial indices including any index of
Municipal Securities or U.S. Government Securities ("futures contracts") and ACM
Municipal Securities may purchase and write put and call options to buy or sell
futures contracts ("options on futures contracts"). A "sale" of a futures
contract means the acquisition of a contractual obligation to deliver the
securities called for by the contract at a specified price on a specified date.
A "purchase" of a futures contract means the incurring of a contractual
obligation to acquire the securities called for by the contract at a specified
price on a specified date. The purchaser of a futures contract on an index
agrees to take or make delivery of an amount of cash equal to the difference
between a specified dollar multiple of the value of the index on the expiration
date of the contract ("current contract value") and the price at which the
contract was originally struck. No physical delivery of the fixed-income
securities underlying the index is made. Options on futures contracts to be
written or purchased by ACM Municipal Securities will be traded on U.S.
exchanges or over-the-counter. These investment techniques are used only to
hedge against anticipated future changes in market conditions and interest rates
that otherwise might either adversely affect the value of a Fund's portfolio
securities or adversely affect the prices of securities which a Fund intends to
purchase at a later date.

     ACM Municipal Securities has adopted the requirement that futures contracts
and options on futures contracts may only be used as a hedge and may not be used
for speculation. In addition to this requirement, the ACM Municipal Securities
Board has also adopted two percentage restrictions on the use of futures
contracts that reflect previous requirements of the Commodity Futures Trading
Commission. The first restriction is that the Fund will not enter into any
futures contracts or options on futures contracts if immediately thereafter the
aggregate amount of initial margin deposits on all the futures contracts of the
Fund and premiums paid on options on futures contracts would exceed 5% of the
market value of the total assets of the Fund. The second restriction is that the
aggregate market value of the futures contracts purchased by the Fund not exceed
50% of the market value of the total assets of the Fund. Neither of these
restrictions will be changed by the Board without considering the policies and
concerns of the various applicable federal and state regulatory agencies.

     Interest Rate Transactions (Swaps, Caps, and Floors). While Alliance
National Municipal does not currently intend to do so, both Funds may enter into
interest rate swap, cap, or floor transactions primarily for hedging purposes,
which may include preserving a return or spread on a particular investment or
portion of its portfolio or protecting against an increase in the price of
securities the Funds anticipate purchasing at a later date. The Funds do not
intend to use these transactions in a speculative manner. Interest rate swaps
involve the exchange by a Fund with another party of their respective
commitments to pay or receive interest, e.g., an exchange of floating rate
payments for fixed rate payments. The purchase of an interest rate cap entitles
the purchaser, to the extent that a specified index exceeds a predetermined
interest rate, to receive payments of interest on a contractually-based
principal amount from the party selling such interest rate cap. The purchase of
an interest rate floor entitles the purchaser, to the extent that a specified
index falls below a predetermined interest rate, to receive payments of interest
on a contractually-based principal amount from the party selling such interest
rate floor.

     The Funds may enter into interest swaps, caps, and floors on either an
asset-based or liability-based basis, depending upon whether it is hedging its
assets or its liabilities, and will usually enter into interest rate swaps on a
net basis, i.e., the two payment streams are netted out, with a Fund receiving
or paying, as the case may be, only the net amount of the two payments. The net
amount of the excess, if any, of a Fund's obligations over its entitlements with
respect to each interest rate swap will be accrued on a daily basis and an
amount of cash or high-quality liquid fixed income securities having an
aggregate NAV at least equal to the accrued excess will be maintained in a
segregated account by a Fund's Custodian. If a Fund enters into an interest rate
swap other than on a net basis, the Fund would maintain a segregated account in
the full amount accrued on a daily basis of the Fund's obligations with respect
to the swap. A Fund will not enter into any interest rate swap, cap, or floor
transaction unless the unsecured senior debt or the claims-paying ability of the
other party thereto is rated in the highest rating category of at least one
nationally recognized ratings organization at the time of entering into the
transaction. The Adviser will monitor the creditworthiness of counterparties on
an ongoing basis. If there is a default by the other party to such a
transaction, a Fund will have contractual remedies pursuant to the agreements
related to the transaction. The swap market has grown substantially in recent
years with a large number of banks and investment banking firms acting both as
principals and as agents utilizing standardized swap documentation. The Adviser
has determined that, as a result, the swap market has become relatively liquid.
Caps and floors are more recent innovations for which standardized documentation
has not yet been developed and, accordingly, are less liquid than swaps. To the
extent a Fund sells (i.e., writes) caps and floors it will maintain in a
segregated account cash, or high-quality liquid debt securities having an
aggregate NAV at least equal to the full amount, accrued on a daily basis, of a
Fund's obligations with respect to any caps or floors. The use of interest rate
swaps is a highly specialized activity that involves investment techniques and
risks different from those associated with ordinary portfolio securities
transactions. If the Adviser is incorrect in its forecasts of market values,
interest rates and other applicable factors, the investment performance of a
Fund would diminish compared with what it would have been if these investment
techniques were not used. Moreover, even if the Adviser is correct in its
forecasts, there is a risk that the swap position may correlate imperfectly with
the price of the asset or liability being hedged.

     There is no limit on the amount of interest rate swap transactions into
which a Fund may enter. These transactions do not involve the delivery of
securities or other underlying assets of principal. Accordingly, the risk of
loss with respect to interest rate swaps is limited to the net amount of
interest payments a Fund is contractually obligated to make. If the other party
to an interest rate swap defaults, a Fund's risk of loss consists of the net
amount of interest payments that a Fund is contractually entitled to receive. A
Fund may purchase and sell (i.e., write) caps and floors without limitation,
subject to the segregated account requirement described above.

     Derivatives. The Funds may use derivatives. Derivatives are financial
contracts whose value depends on, or is derived from, the value of an underlying
asset, reference rate, or index. These assets, rates, and indices may include
bonds, stocks, mortgages, commodities, interest rates, bond indices, and stock
indices. Generally, there are four types of derivative instruments - options,
futures, forwards, and swaps - from which virtually any type of derivative
transaction can be created. While Alliance National Municipal does not currently
intend to utilize any of these types of derivative instruments, it reserves the
flexibility to use these techniques under appropriate circumstances. Derivatives
can be used to earn income or protect against risk, or both. The Funds may use
derivatives to earn income and enhance returns, to hedge or adjust the risk
profile of its investment portfolio, or to obtain exposure to otherwise
inaccessible markets. The Funds will generally use derivatives primarily as
direct investments in order to enhance yields. Each of these uses entails
greater risk than if derivatives were used solely for hedging purposes. The
successful use of derivatives depends upon the Adviser's ability to assess the
risk that a derivative adds to a Fund's portfolio and to forecast price and
interest rate movements correctly. Since many derivatives may have a leverage
component, adverse changes in the value or level of the underlying asset, rate,
or index can result in a loss substantially greater than the amount invested in
the derivative.

     Lending of Portfolio Securities. The Funds may not make loans except
through: (i) the purchase of debt obligations in accordance with their
investment objectives and policies, or (ii) the use of repurchase agreements.

     Forward Commitments. ACM Municipal Securities may enter into forward
commitments for the purchase or sale of securities. Alliance National Municipal
may purchase or sell municipal bonds on a forward commitment basis. Such
transactions may include purchases on a "when-issued" basis or purchases or
sales on a "delayed delivery" basis. In some cases, a forward commitment may be
conditioned upon the occurrence of a subsequent event, such as approval of a
proposed financing by appropriate municipal authorities (i.e., a "when, as, and
if issued" trade).

     When forward commitment transactions are negotiated, the price, which is
generally expressed in yield terms, is fixed at the time the commitment is made,
but delivery and payment for the securities take place at a later date.
Normally, the settlement date occurs within two months after the transaction,
but delayed settlements beyond two months may be negotiated. Securities
purchased or sold under a forward commitment are subject to market fluctuation,
and no interest accrues to the purchaser prior to the settlement date. At the
time a Fund enters into a forward commitment, it will record the transaction and
thereafter reflect the value of the security purchased or, if sold, the proceeds
to be received, in determining the NAV of its shares. Any unrealized
appreciation or depreciation reflected in such valuation of a "when, as, and if
issued" security would be cancelled in the event that the required condition did
not occur and the trade was cancelled.

     The use of forward commitments enables a Fund to protect against
anticipated changes in interest rates and prices. For instance, in periods of
rising interest rate and falling bond prices, a Fund might sell securities in
its portfolio on a forward commitment basis to limit its exposure to falling
prices. In periods of falling interest rates and rising bond prices, a Fund
might sell a security in its portfolio and purchase the same or a similar
security on a when-issued or forward commitment basis, thereby obtaining the
benefit of currently higher cash yields. However, if the Adviser were to
forecast incorrectly the direction of interest rate movements, a Fund might be
required to complete such when-issued of forward transactions at prices inferior
to then current market values. No forward commitments will be made by ACM
Municipal Securities if, as a result, ACM Municipal Securities' aggregate
commitments under such transactions would be more than 30% of the then current
value of ACM Municipal Securities' total assets. No forward commitments will be
made by Alliance National Municipal if, as a result, Alliance National
Municipal's aggregate commitments under such transactions would be more than 10%
of Alliance National Municipal's total assets.

     The Funds' right to receive or deliver a security under a forward
commitment may be sold prior to the settlement date, but each Fund enters into
forward commitments only with the intention of actually receiving or delivering
the securities, as the case may be. To facilitate such transactions, each Fund's
Custodian will maintain, in a segregated account of each Fund, cash or liquid
high-grade debt securities having value equal to, or greater than, any
commitments to purchase securities on a forward commitment basis and, with
respect to forward commitments to sell portfolio securities of a Fund, the
portfolio securities themselves. If a Fund, however, chooses to dispose of the
right to receive or deliver a security subject to a forward commitment prior to
the settlement date of the transaction, it may incur a gain or loss. In the
event the other party to a forward commitment transaction were to default, a
Fund might lose the opportunity to invest money at favorable rates or to dispose
of securities at favorable prices.

     General Information Regarding Futures, Options and Forward Contracts. The
successful use of the foregoing investment practices draws upon the Adviser's
special skill and experience with respect to such instruments and usually
depends on the Adviser's ability to forecast interest and exchange rate
movements correctly. Should interest or exchange rates move in an unexpected
manner, a Fund may not achieve the anticipated benefits of the use of these
techniques or may realize losses and thus be in a worse position than if such
strategies had not been used. Unlike many exchange-traded futures contracts and
options on futures contracts, there are no daily price fluctuation limits with
respect to forward contracts, and adverse market movements could therefore
continue to an unlimited extent over a period of time. In addition, the
correlation between movements in the prices of such instruments and movements in
the price of the securities hedged or used for cover will not be perfect and
could produce unanticipated losses.

     A Fund's ability to dispose of its positions in futures contracts, options
and forward contracts will depend on the availability of liquid markets in such
instruments. It is impossible to predict the amount of trading interest that may
exist in various types of futures contracts, options and forward contracts. If a
secondary market does not exist with respect to an option purchased or written
by a Fund over-the-counter, it might not be possible to effect a closing
transaction in the option (i.e., dispose of the option) with the result that (i)
an option purchased by a Fund would have to be exercised in order for a Fund to
realize any profit and (ii) a Fund may not be able to sell portfolio securities
covering an option written by a Fund until the option expires or it delivers the
underlying security or futures contract upon exercise. Therefore, no assurance
can be given that a Fund will be able to utilize these instruments at all or
utilize them effectively for the purposes set forth above. Furthermore, a Fund's
ability to engage in options and futures transactions may be limited by tax
considerations. See "Taxation - U.S. Federal Income Taxation of a Fund."

     Repurchase Agreements. While Alliance National Municipal does not intend to
do so, both Funds may enter into repurchase agreements pertaining to U.S.
Government Securities with member banks of the Federal Reserve System or
"primary dealers" (as designated by the Federal Reserve Bank of New York) in
such securities. Currently, ACM Municipal Securities plans to enter into
repurchase agreements only with its Custodian and such primary dealers. A
repurchase agreement arises when a buyer such as a Fund purchases a security and
simultaneously agrees to resell it to the vendor at an agreed-upon future date,
normally one day or a few days later. The resale price is greater than the
purchase price, reflecting an agreed-upon interest rate which is effective for
the period of time the buyer's money is invested in the security and which is
related to the current market rate rather than the coupon rate on the purchased
security. Such agreements permit a Fund to keep all of its assets at work while
retaining "overnight" flexibility in pursuit of investments of a longer-term
nature. A Fund requires continual maintenance by its Custodian for its account
in the Federal Reserve/Treasury Book Entry System of collateral in an amount
equal to, or in excess of, the resale price. If a vendor defaults on its
repurchase obligation, a Fund would suffer a loss to the extent that the
proceeds from the sale of the collateral were less than the repurchase price. In
the event of a vendor's bankruptcy, a Fund might be delayed in, or prevented
from, selling the collateral for a Fund's benefit. Each Fund's Board of
Directors ("Board") has established procedures, which are periodically reviewed
by the Board, pursuant to which the Adviser monitors the creditworthiness of the
dealers with which a Fund enters into repurchase agreement transactions.

     Reverse Repurchase Agreements. Reverse repurchase agreements involve sales
by a Fund of portfolio assets concurrent with an agreement by a Fund to
repurchase the same assets at a later date at a fixed price. During the reverse
repurchase agreement period, a Fund continues to receive principal and interest
payments on these securities. Generally, the effect of such a transaction is
that a Fund can recover all or most of the cash invested in the portfolio
securities involved during the term of the reverse repurchase agreement, while
it will be able to keep the interest income associated with those portfolio
securities. Such transactions are advantageous only if the interest cost to a
Fund of the reverse repurchase transaction is less than the cost of otherwise
obtaining the cash.

     Reverse repurchase agreements involve the risk that the market value of the
securities a Fund is obligated to repurchase under the agreement may decline
below the repurchase price. In the event the buyer of securities under a reverse
repurchase agreement files for bankruptcy or becomes insolvent, a Fund's use of
the proceeds of the agreement may be restricted pending a determination by the
other party, or its trustee or receiver, whether to enforce a Fund's obligation
to repurchase the securities.

     Short Sales. ACM Municipal Securities may make short sales of securities or
maintain a short position only for the purpose of deferring realization of gain
or loss for U.S. federal income tax purposes, provided that at all times when a
short position is open the Fund owns an equal amount of such securities of the
same issue as, and equal in amount to, the securities sold short. In addition,
ACM Municipal Securities may not make a short sale if more than 10% of the
Fund's net assets (taken at market value) are held as collateral for short sales
at any one time. If the price of the security sold short increases between the
time of the short sale and the time ACM Municipal Securities replaces the
borrowed security, the Fund will incur a loss; conversely, if the price
declines, the Fund will realize a capital gain. Although ACM Municipal
Securities gain is limited to the price at which it sold the security short, its
potential loss is unlimited. Certain special federal income tax considerations
may apply to short sales entered into by ACM Municipal Securities. See "Taxation
- Tax Straddles."

     Variable and Floating Rate Instruments. Fixed-income securities may have
fixed, variable, or floating rates of interest. Variable and floating rate
securities pay interest at rates that are adjusted periodically, according to a
specified formula. A "variable" interest rate adjusts at predetermined intervals
(e.g., daily, weekly, or monthly), while a "floating" interest rate adjusts
whenever a specified benchmark rate (such as the bank prime lending rate)
changes.

     The Funds may invest in variable rate demand notes, which are instruments
whose interest rates change on a specific date (such as coupon date or interest
payment date) or whose interest rates vary with changes in a designated base
rate (such as prime interest rate). This instrument is payable on demand and is
secured by letters of credit or other credit support agreements from major
banks.

     The Funds may invest in fixed-income securities that pay interest at a
coupon rate equal to a base rate, plus additional interest for a certain period
of time if short-term interest rates rise above a predetermined level or "cap."
The amount of such an additional interest payment typically is calculated under
a formula based on a short-term interest rate index multiplied by a designated
factor.

     Illiquid Securities. The Funds may invest in illiquid securities, which
include, among others, (i) direct placements or other securities that are
subject to legal or contractual restrictions on resale or for which there is no
readily available market (e.g., trading in the security is suspended or, in the
case of unlisted securities, market makers do not exist or will not entertain
bids or offers), (ii) options purchased by a Fund over-the-counter and the cover
for options written by a Fund over-the-counter, and (iii) repurchase agreements
not terminable within seven days. Securities that have legal or contractual
restrictions on resale but have a readily available market are not deemed
illiquid for purposes of this limitation.

     Illiquid securities generally include securities subject to contractual or
legal restrictions on resale because they have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), securities that are
otherwise not readily marketable, and repurchase agreements having a maturity of
longer than seven days. Securities that have not been registered under the
Securities Act are referred to as private placements or restricted securities
and are purchased directly from the issuer or in the secondary market.

     Rule 144A under the Securities Act permits a broader institutional trading
market for securities otherwise subject to restriction on resale to the general
public. Rule 144A establishes a "safe harbor" from the registration requirements
of the Securities Act for resales of certain securities to qualified
institutional buyers. An insufficient number of qualified institutional buyers
interested in purchasing certain restricted securities held by a Fund, however,
could affect adversely the marketability of such Fund securities. The Adviser,
acting under the supervision of the Board, will monitor the liquidity of
restricted securities in a Fund that are eligible for resale pursuant to Rule
144A. In reaching liquidity decisions, the Adviser will consider, among others,
the following factors: (1) the frequency of trades and quotes for the security;
(2) the number of dealers issuing quotations to purchase or sell the security;
(3) the number of other potential purchasers of the security; (4) the number of
dealers undertaking to make a market in the security; (5) the nature of the
security (including its unregistered nature) and the nature of the marketplace
for the security (e.g., the time needed to dispose of the security, the method
of soliciting offers, and the mechanics of the transfer); and (6) any applicable
Commission interpretation or position with respect to such type of securities.

     Future Developments. The Funds may, following written notice to their
stockholders, take advantage of other investment practices which are not at
present contemplated for use by the Funds or which currently are not available
but which may be developed, to the extent such investment practices are both
consistent with a Fund's investment objectives and legally permissible for a
Fund. Such investment practices, if they arise, may involve risks that exceed
those involved in the activities described above.

                             INVESTMENT RESTRICTIONS

     Each Fund has adopted the following investment restrictions, which may not
be changed without the approval of the holders of a majority of that Fund's
outstanding voting securities as defined above. The percentage limitations set
forth below, as well as those described in the Prospectus/Proxy Statement and
elsewhere in this Statement of Additional Information, apply only at the time an
investment is made or other relevant action is taken by a Fund.

     Each Fund will not:

     1.   Make loans except through (a) the purchase of debt obligations in
          accordance with its investment objective and policies; or (b) the use
          of repurchase agreements.

     2.   Pledge, hypothecate, mortgage or otherwise encumber its assets, except
          (i) to secure permitted borrowings, (ii) in connection with initial
          and variation margin deposits relating to futures contracts, and (iii)
          any segregated accounts established in accordance with its investment
          objective and policies.

     Alliance National Municipal will not:

     1.   Concentrate its investments in a particular industry, as that term is
          used in the 1940 Act and as interpreted, modified, or otherwise
          permitted by regulatory authority having jurisdiction, from time to
          time. (The Fund's industry concentration policy does not preclude it
          from focusing investments in issuers in a group of related industries,
          such as different types of utilities.)

     2.   Purchase or sell real estate, although it may purchase securities
          (including municipal bonds) secured by real estate or interests
          therein, or securities issued by companies which invest in real
          estate, or interests therein.

     3.   Purchase or sell commodities or commodities contracts or oil, gas or
          mineral programs. This restriction shall not prohibit the Fund,
          subject to restrictions described in the Prospectus and elsewhere in
          this SAI, from purchasing, selling or entering into futures contracts,
          options on futures contracts, forward contracts, or any interest rate,
          securities-related or other hedging instruments, including swap
          agreements and other derivative instruments, subject to compliance
          with any applicable provisions of the federal securities or
          commodities laws.

     4.   Borrow money or issue any senior security, except in accordance with
          provisions of the 1940 Act, and specifically, the Fund may (a) borrow
          from a bank or other entity in a privately arranged transaction and
          issue commercial paper, bonds, debentures or notes, in series or
          otherwise, with such interest rates, conversion rights and other terms
          and provisions as are determined by the Fund's Board of Directors, if
          after such borrowing or issuance there is asset coverage of at least
          300% as defined in the 1940 Act; and (b) issue preferred shares with
          such preferences, conversion and other rights, voting powers,
          restrictions, limitations as to dividends and other distributions,
          qualifications, and terms and conditions of redemption as are
          determined by the Fund's Board of Directors, if after such issuance
          there is asset coverage of at least 200% as defined in the 1940 Act.

     5.   Act as an underwriter of securities of other issuers, except to the
          extent that in connection with the disposition of portfolio
          securities, it may be deemed to be an underwriter under the federal
          securities laws.

     ACM Municipal Securities will not:

     1.   Invest 25% or more of its total assets in any one industry, provided
          that such limitation shall not be applicable to municipal securities
          other than those municipal securities backed only by assets and
          revenues of non-governmental users.

     2.   With respect to 75% of its total assets, invest more than 5% of the
          value of its total assets (taken at market value at time of purchase)
          in the outstanding securities of any one issuer or own more than 10%
          of the outstanding voting securities of any one issuer, in each case
          other than securities issued or guaranteed by the U.S. Government or
          any agency or instrumentality thereof or other investment companies.

     3.   Borrow money or issue senior securities, except the Fund may, in
          accordance with provisions of the 1940 Act, (a) borrow from a bank or
          other entity in a privately arranged transaction and issue commercial
          paper, bonds, debentures or notes, in series or otherwise, with such
          interest rates, conversion rights and other terms and provisions as
          are determined by the Fund's Board of Directors, if after such
          borrowing or issuance there is asset coverage of at least 300% as
          defined in the 1940 Act; (b) issue preferred stock with such
          preferences, conversion and other rights, voting powers, restrictions,
          limitations as to dividends, qualifications, and terms and conditions
          of redemption as are determined by the Fund's Board of Directors, if
          after such issuance there is asset coverage of at least 200% as
          defined in the 1940 Act; and (c) borrow for temporary purposes in an
          amount not exceeding 5% of the value of the total assets of the Fund.

     4.   Invest in companies for the purpose of exercising control.

     5.   Make short sales of securities or maintain a short position, unless at
          all times when a short position is open it owns an equal amount of
          such securities or securities convertible into or exchangeable for,
          without payment of any further consideration, securities of the same
          issue as, and equal in amount to, the securities sold short ("short
          sales against the box"), and unless not more than 10% of the Fund's
          net assets (taken at market value) is held as collateral for such
          sales at any one time (it is the Fund's present intention to make such
          sales only for the purpose of deferring realization of gain or loss
          for federal income tax purposes).

     6.   (i) Purchase or sell real estate, except that it may purchase and sell
          securities of companies which deal in real estate or interests
          therein, (ii) purchase or sell commodities or commodity contracts
          (except forward contracts or contracts for the future acquisition or
          delivery of debt securities and related options, futures contracts and
          options on futures contracts and other similar contracts), (iii) write
          put and call options except in accordance with its investment
          objective and policies, (iv) invest in interests in oil, gas or other
          mineral exploration or development programs, except that it may
          purchase and sell securities of companies that deal in oil, gas or
          other mineral exploration or development programs, (v) purchase
          securities on margin, except for such short-term credits as may be
          necessary for the clearance of transactions or (vi) act as an
          underwriter of securities, except that the Fund may acquire restricted
          securities under circumstances in which, if such securities were sold,
          the Fund might be deemed to be an underwriter within the meaning of
          the Securities Act of 1933, as amended.

                     RISK FACTORS AND SPECIAL CONSIDERATIONS

     Risk is inherent in all investing. Investing in any investment company
security involves risks, including the risks that you may receive little or no
return on your investment or even that you may lose all or part of your
investment. Therefore, you should consider carefully the following risks before
investing in the shares of Alliance National Municipal.

GENERAL RISKS OF INVESTING IN THE FUNDS

     General. The NAV of shares of a Fund varies as the aggregate value of a
Fund's portfolio securities increases or decreases. A Fund's NAV changes as the
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed-income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed-income securities can be expected to decline. If the Adviser's expectation
of changes in interest rates or its evaluation of the normal yield relationships
in the fixed-income markets proves to be incorrect, a Fund's income, NAV and
potential capital gain may be decreased or its potential capital loss may be
increased.

     ACM Municipal Securities expects that the dollar-weighted average maturity
of its investments will be approximately 15 to 20 years. Alliance National
Municipal expects that the dollar-weighted average maturity of its investments
will be approximately 15-30 years. In general, the longer the maturity of a
security, the higher the rate of interest it pays. However, a longer average
maturity is generally associated with a higher level of volatility in the market
value of a security. The average maturity of the Funds' portfolios will vary
depending on anticipated market conditions.

     Although changes in the value of a Fund's portfolio securities subsequent
to their acquisition are reflected in a Fund's NAV, such changes will not affect
the income received by a Fund from such securities. The dividends paid by a Fund
increase or decrease in relation to the income received by a Fund from its
investments, which is reduced by a Fund's expenses before being distributed to a
Fund's stockholders.

     A Fund's use of options, futures contracts, options on futures contracts,
interest rate transactions, and forward commitment contracts may result in the
loss of principal under certain market conditions.

     For these reasons, an investment in shares of a Fund should not constitute
a complete investment program and may not be appropriate for investors who
cannot assume the greater risk of capital depreciation inherent in seeking
higher income.

     Interest Rate Risk. Interest rate risk is the risk that changes in interest
rates will adversely affect the yield or value of a Fund's investments in
municipal bonds. When interest rates rise, the value of a Fund's investment
tends to fall, and this decrease in value may not be offset by higher interest
income from new investments. Interest rate risk is generally greater for
investment companies like the Funds that invest in municipal bonds with longer
maturities or durations. The value of these securities is affected more by
changes in interest rates because when interest rates rise, the maturities of
these types of securities tend to lengthen and the value of the securities
decreases more significantly, which, in turn reduces the asset coverage on the
Funds' preferred shares. In addition, these types of securities are subject to
prepayment when interest rates fall, which generally results in lower returns
because a Fund must reinvest its assets in municipal bonds with lower interest
rates. A Fund may utilize certain strategies for the purpose of reducing the
interest rate sensitivity of the portfolio and decreasing the Fund's exposure to
interest rate risk, although there is no assurance that it will do so or that
such strategies will be successful.

     Credit Risk. Credit risk is the risk that the issuer or guarantor of a
municipal bond or the guarantor to a derivatives or other contract, will be
unable or unwilling to make timely payments of interest or principal or to
otherwise honor its obligations. The issuer or guarantor may default causing a
loss of the full principal amount of a security and any accrued interest. The
degree of risk for a particular security may be reflected in its credit rating.
Investments in municipal bonds with lower ratings tend to have a higher
probability that an issuer will default or fail to meet its payment obligations.

     Because Alliance National Municipal may invest up to 25% (measured at the
time of investment) of its net assets in municipal bonds that are rated below
investment grade or, if unrated, determined to be of comparable quality by the
Adviser, Alliance National Municipal is more susceptible to credit risk. The
prices of these lower-grade municipal bonds are more sensitive to negative
developments, such as a decline in the issuer's revenues or a general economic
turndown, than are the prices of higher-grade securities.

     Municipal bonds of below investment grade quality (commonly referred to as
"junk bonds") are predominately speculative with respect to the issuer's
capacity to pay interest and repay principal when due, and therefore involve a
greater risk of default. Municipal bonds in the lowest investment grade category
may also be considered to possess some speculative characteristics by certain
rating agencies. Any default by an issuer of a municipal bond could have a
negative effect on a Fund's ability to pay dividends on its preferred stock and
could result in the redemption of some or all of the preferred stock.

     Effects of Leverage. The Funds use financial leverage for investment
purposes. When a Fund borrows money or otherwise leverages its portfolio, it may
be more volatile because leverage tends to exaggerate the effect of any increase
or decrease in the value of the portfolio's investments. Leverage risk includes
the risk associated with the issuance of preferred shares to leverage a Fund's
common stock. Long-term municipal bond rates of return are typically, although
not always, higher than short-term municipal bond rates of return. If the
dividend rate on the preferred stock exceeds the net rate of return on a Fund's
portfolio, the leverage will result in a lower NAV than if a Fund were not
leveraged, and a Fund's ability to pay dividends and meet its asset coverage
tests would be reduced.

     Investment by the Funds in derivative instruments may amplify the effects
of leverage.

     Because the management fees received by the Adviser are based on the total
net assets of a Fund (including assets acquired with the proceeds of preferred
stock), the Adviser has a financial incentive for a Fund to use leverage and
issue preferred stock.

     Derivatives Risk. The Funds may use derivatives to achieve their investment
objectives. In addition to the credit risk of the counterparty to a derivatives
transaction, derivatives involve the risk of difficulties in pricing and
valuation and the risks that changes in value of a derivative may not correlate
perfectly with relevant underlying assets, rates, or indexes.

     Market Risk and Net Asset Value of Shares. This is the risk that the value
of a Fund's investments will fluctuate as municipal bond markets fluctuate and
that prices overall will decline over shorter or longer-term periods. Shares of
common stock of closed-end investment companies, such as the Funds, frequently
trade at a discount to their NAVs. Whether an investor will realize gains or
losses upon the sale of shares of a Fund does not depend directly upon changes
in a Fund's NAV, buy rather upon whether the market price of the shares at the
time of sale is above or below the investor's purchase price for the shares. The
market price of the shares of each Fund is determined by such factors as
relative demand for and supply of the shares in the market, general market and
economic conditions, changes in a Fund's NAV and other factors beyond the
control of a Fund. This market risk is separate and distinct from the risk that
each Fund's NAV may decrease.

     Municipal Bond Market Risk. This is the risk that special factors, such as
legislative changes and local and business developments, may adversely affect
the yield or value of a Fund's investments in municipal bonds or other municipal
securities. The amount of public information available about municipal bonds is
generally less than that for corporate equities or bonds, and the investment
performance for a Fund may therefore be more dependent on the analytical
abilities of the Adviser than would be the case for a stock fund or taxable bond
fund. The secondary market for municipal bonds, particularly below investment
grade municipal bonds in which the Funds may invest, also tends to be less
developed and less liquid than many other securities markets, which may
adversely affect a Fund's ability to sell its municipal bonds at attractive
prices.

     Reinvestment Risk. Reinvestment risk is the risk that income from the
Funds' municipal bond portfolio will decline if and when the Funds invest the
proceeds from matured, traded, or called municipal bonds at market interest
rates that are below the portfolio's current earnings rate. A decline in income
could affect the Funds' NAV or reduce asset coverage on the preferred stock.

     Inflation Risk. Inflation risk is the risk that the value of assets or
income from an investment will be worth less in the future as inflation
decreases the value of money. As inflation increases, the real value of the
preferred stock or the income from that investment will be less in the future.
During any periods of rising inflation, however, preferred stock dividend rates
are expected, through the auction process, to increase, tending to reduce this
risk.

     Securities Ratings Risk. In the case of securities rated BBB by S&P or Baa
by Moody's, sustained periods of deteriorating economic conditions or rising
interest rates are more likely to lead to a weakening in the issuer's capacity
to pay interest and repay principal than in the case of higher-rated securities.
Securities rated Baa are considered by Moody's to have speculative
characteristics. The ratings of fixed-income securities by S&P and Moody's are a
generally accepted barometer of credit risk. They are, however, subject to
certain limitations from an investor's standpoint. The rating of an issuer is
heavily weighted by past developments and does not necessarily reflect probable
future conditions. There is frequently a lag between the time a rating is
assigned and the time it is updated. In addition, there may be varying degrees
of difference in credit risk of securities within each credit rating. See
Appendix A herein for a description of such ratings.

     ACM Municipal Securities may invest up to 20% of its total assets in
securities that are not rated. Non-rated securities will also be considered for
investment by ACM Municipal Securities when the Adviser believes that the
financial condition of the issuers of such securities, or the protection
afforded by the terms of the securities themselves, limits the risk to the Fund
to a degree comparable to that of rated securities that are consistent with the
Fund's objective and policies.

     Securities Not Readily Marketable. Both Funds may invest in securities that
are not readily marketable. (ACM Municipal Securities may invest up to 10% of
its total assets in securities that are not readily marketable.) These
securities include, among others, securities for which there is no readily
available market (e.g., trading in the security is suspended, or, in the case of
unlisted securities, market makers do not exist or will not entertain bids or
offers), options purchased by a Fund over-the-counter and the cover for options
written by a Fund over-the-counter, and repurchase agreements not terminable
within seven days. Because of the absence of a trading market for these
investments, a Fund may not be able to realize their value upon sale.

     Portfolio Management and Other Considerations. In the event of an increase
in yields on short-term securities or other changes in market conditions, to the
extent that a Fund's leveraged capital structure could adversely affect the
holders of the common stock (as noted above), or in anticipation of such
increase or changes, a Fund may attempt to shorten the average maturity of its
investment portfolios, which would tend to offset partially the negative effect
of such structure on the holders of the common stock. A Fund also may attempt to
reduce the degree to which their capital structure is leveraged by redeeming or
otherwise purchasing the preferred stock. Purchases of preferred stock, whether
on the open market or in negotiated transactions, are subject to limitations
under the 1940 Act. If market conditions subsequently change, a Fund may sell
previously unissued shares of preferred stock or shares of preferred stock that
a Fund previously issued but later repurchased. However, such sales could be
made only pursuant to an effective registration statement under the Securities
Act, or pursuant to an exemption from registration.

     Under the 1940 Act, a Fund is not permitted to issue shares of preferred
stock unless immediately after such issuance the asset coverage of a Fund's
portfolio is at least 200% of the liquidation value of the outstanding preferred
stock (expected to equal original purchase price per share plus any accrued and
unpaid dividends). In addition, a Fund is not permitted to declare any cash
dividend or other distributions on their common stock unless, at the time of
such declaration, the NAV of a Fund's portfolio (determined after deducting the
amount of such dividend or other distribution) is at least 200% of such
liquidation value.

     Borrowing. The Funds reserve the right to borrow money, or issue debt
securities, to the extent permitted under the 1940 Act. At present, the Funds
have no intention of borrowing money or issuing senior securities except that
the Funds intend to offer shares of preferred stock as described above. The
Funds may also borrow to finance repurchases of or tenders for their shares when
they deem it desirable in order to avoid the untimely disposition of portfolio
securities.

     The 1940 Act requires a Fund to maintain "asset coverage" of not less than
300% of its "senior securities representing indebtedness," as those terms are
defined and used in the 1940 Act. In addition, under the 1940 Act, a Fund may
not make any cash distributions to stockholders if, after the distribution,
there would be less than 300% asset coverage of a senior security representing
indebtedness for borrowings (excluding for this purpose certain evidences of
indebtedness made by a bank or other entity and privately arranged, and not
intended to be publicly distributed). This limitation on a Fund's ability to
make distributions could under certain circumstances impair a Fund's ability to
maintain its qualification for taxation as a registered investment company.

     ACM Municipal Securities may also borrow for temporary purposes in an
amount not exceeding 5% of the value of the total assets of the Fund. Such
borrowings are not subject to the asset coverage restrictions set forth in the
preceding paragraph.

     Any investment gains made with the proceeds obtained from borrowings in
excess or interest paid on the borrowings will cause the net income per share or
the NAV per share of a Fund's common stock to be greater than would otherwise be
the case. On the other hand, if the investment performance of the additional
securities purchased fails to cover their cost (including any interest paid on
the money borrowed) to a Fund, then the net income per share or NAV per share of
a Fund's common stock will be less than would otherwise be the case. This is the
speculative factor known as "leverage."

     Repurchase of Shares. In recognition of the possibility that a Fund's
shares might trade at a discount to NAV, each Fund's Board has determined that
it would be in the interest of stockholders of a Fund to attempt to reduce or
eliminate any market value discount should it exist for an extended period of
time. To that end, each Fund's Board will from time to time contemplate a share
repurchase or tender offer for its own shares at NAV. The Funds are closed-end
investment companies and as such, their stockholders will not have the right to
cause a Fund to redeem their shares. Instead, the Funds' common stock will trade
in the open market at prices that will be a function of several factors,
including dividend levels (which are in turn affected by expenses), NAV,
quality, average maturity and call protection of its portfolio securities,
price, dividend stability, relative demand for and supply of such shares in the
market, general market and economic conditions and other factors. Shares of a
closed-end investment company may frequently trade at prices lower than NAV.
Each Fund's Board of Directors will regularly monitor the relationship between
the market price and NAV of the common stock. If the common stock were to trade
at a substantial discount to NAV for an extended period of time, a Fund may
consider the repurchase by a Fund of its common stock or the making of a tender
offer for such shares. The Funds have no present intention to repurchase their
common stock.

     Notwithstanding the foregoing, at any time when preferred stock is
outstanding, a Fund may not purchase, redeem or otherwise acquire any of its
common stock unless (1) all accrued preferred stock dividends have been paid and
(2) at the time of such purchase, redemption or acquisition, the NAV of a Fund's
portfolio (determined after deducting the acquisition price of the common stock)
is at least 200% of the liquidation value of the outstanding preferred stock
(expected to equal the original purchase price per share plus any accrued and
unpaid dividends thereon).

     Subject to a Fund's fundamental policy with respect to borrowings, a Fund
may incur debt to finance repurchases and/or tender offers. Interest on any such
borrowing will reduce a Fund's net income.

     The repurchase by a Fund of its shares at prices below NAV will result in
an increase in the NAV of those shares that remain outstanding. However, there
can be no assurance that share repurchases or tender offers at or below NAV will
result in a Fund's shares trading at a price equal to its NAV. Nevertheless, the
fact that a Fund's shares may be the subject of repurchase or tender offers at
NAV from time to time, or that a Fund may be converted to an open-end company,
may reduce any spread between market price and NAV that might otherwise exist.

     In addition, a purchase by a Fund of its shares would decrease a Fund's
total assets, which would likely have the effect of increasing a Fund's expense
ratio and may also require the redemption of a portion of any outstanding
preferred stock in order to maintain coverage ratios. Any purchase by a Fund of
its common stock at a time when preferred stock is outstanding will increase the
leverage applicable to the outstanding common stock then remaining.

     Before deciding whether to take any action if a Fund's common stock trade
substantially below NAV, the Board of Directors would consider all factors that
it deemed relevant. Such factors may include the extent and duration of the
discount, the liquidity of a Fund's portfolio, the relationship of the market
price of the common stock to NAV, the extent to which a Fund's capital structure
is leveraged and the possibility of re-leveraging the spread, if any, between
the yields on securities in a Fund's portfolio and interest and dividend charges
on preferred stock issued by a Fund, the effect of any action that might be
taken on a Fund or its stockholders and general market and economic
considerations. Based on these considerations, even if a Fund's shares should
trade at a substantial discount for a significant period of time, the Board of
Directors may determine that no action should be taken.

     There can be no assurance that repurchases and/or tender offers will result
in a Fund's shares trading at a price equal to their NAV. Each Fund anticipates
that the market price of its shares will from time to time vary from NAV. The
market price of a Fund's shares will, among other things, be affected by the
relative demand for and supply of such shares in the market, a Fund's investment
performance, a Fund's dividends and yield and investor perception of a Fund's
overall attractiveness as an investment as compared with other investment
alternatives. Nevertheless, the fact that a Fund's shares may be the subject of
tender offers at NAV from time to time may reduce the spread that might
otherwise exist between market price and NAV. In the opinion of the Adviser,
sellers may be less inclined to accept a significant discount if they have a
reasonable expectation of being able to recover NAV in conjunction with a
possible tender offer.

     Although each Fund's Board believes that share repurchases and tender
offers might, in certain circumstances have a favorable effect an the market
price of a Fund's shares, it should be recognized that the acquisition of shares
by a Fund would decrease the total assets of a Fund and therefore have the
effect of increasing a Fund's expense ratio. Because of the nature of a Fund's
investment objective, policies and portfolio, each Fund's Adviser does not
anticipate that repurchases and tenders should have an adverse effect on a
Fund's investment performance and does not anticipate any material difficulty in
disposing of portfolio securities in order to consummate stock repurchases and
tenders.

     Possible Future Conversion to Open-End Investment Company. A Fund's Board
of Directors may also from time to time consider submitting for stockholder vote
a proposal to convert a Fund to an open-end investment company in an attempt to
reduce or eliminate the significant market discounts from NAV. Each Fund's
Charter requires the affirmative vote or consent of holders of at least
seventy-five percent (75%) of each class of a Fund's shares entitled to vote on
the matter to authorize a conversion of a Fund from a closed-end to an open-end
investment company. This seventy-five percent (75%) stockholder approval
requirement is higher than is required under the 1940 Act.

     If a Fund converted to an open-end company, it would be required to redeem
all preferred stock then outstanding (requiring in turn that it liquidate a
portion of its investment portfolio), and a Fund's common stock likely would no
longer be listed on the NYSE. Stockholders of an open-end investment company may
require the company to redeem their shares on any business day (except in
certain circumstances as authorized by or under the 1940 Act) at their NAV, less
such redemption charge, if any, as might be in effect at the time of redemption.
In order to avoid maintaining large cash positions or liquidating favorable
investments to meet redemptions, open-end companies typically engage in a
continuous offering of their shares. Open-end companies are thus subject to
periodic asset in-flows and out-flows that can complicate portfolio management.

     The repurchase by a Fund of its shares would result in an increase in the
NAV of those shares that remain outstanding. However, there can be no assurance
that share repurchases or tender offers at or below NAV will result in a Fund's
shares trading at a price equal to its NAV. Nevertheless, the fact that a Fund's
shares may be the subject of repurchase or tender offers at NAV from time to
time, or that a Fund may be converted to an open-end company, may reduce any
spread between market price and NAV that might otherwise exist.

     In addition, a purchase by a Fund of its shares would decrease the Fund's
total assets, which would likely have the effect of increasing the Fund's
expense ratio and may also require the redemption of a portion of any
outstanding preferred stock in order to maintain coverage ratios. Any purchase
by a Fund of its common stock at a time when preferred stock is outstanding will
increase the leverage applicable to the outstanding common stock remaining.

RISKS OF INVESTING IN PREFERRED STOCK

     Auction Risk. You may not be able to sell the preferred stock at an auction
if the auction fails; that is, if there is more preferred stock offered for sale
than there are buyers for those shares. Also, if you place hold orders (orders
to retain preferred stock) at an auction only at a specified rate, and that bid
rate exceeds the rate set at the auction, you will not retain your preferred
stock. Finally, if you buy shares or elect to retain shares without specifying a
rate below which you would not wish to continue to hold those shares, and the
auction sets a below-market rate, you may receive a lower rate of return on your
shares than the market rate. As a result, your investment in preferred stock may
be illiquid. Neither the participating broker-dealers nor a Fund are obligated
to purchase preferred stock in an auction or otherwise, nor is a Fund required
to redeem the preferred stock in the event of a failed auction.

     Secondary Market Risk. The preferred stock may be illiquid because you may
not be able to sell any or all of your shares if you try to sell the preferred
stock between Auctions. Also, you may not be able to sell them for $25,000 per
share or $25,000 per share plus accumulated dividends. If a Fund has designated
a Special Rate Period, changes in interest rates could affect the price you
would receive if you sold your shares in the secondary market. Broker-Dealers
that maintain a secondary trading market for the preferred stock are not
required to maintain this market, and a Fund is not required to redeem shares if
either an Auction or an attempted secondary market sale fails because of a lack
of buyers. The preferred stock is not registered on a stock exchange or the
NASDAQ stock market. If you sell the preferred stock to a Broker-Dealer between
Auctions, you may receive less than the price you paid for them, especially if
market interest rates have risen since the last Auction. Accrued preferred stock
dividends, however, should at least partially compensate for any increased
market interest rates.

     Ratings and Asset Coverage Risk. While Moody's and S&P assign ratings of
Aaa or AAA to the preferred stock, the ratings do not eliminate or necessarily
mitigate the risks of investing in the preferred stock. A rating agency could
downgrade the preferred stock, which may make your shares less liquid at an
Auction or in the secondary market, though probably with higher resulting
dividend rates. If a rating agency downgrades the preferred stock, a Fund will
alter its portfolio or redeem the preferred stock. A Fund may voluntarily redeem
the preferred stock under certain circumstances.

*    "Interested person" as defined in the Investment Company Act of 1940, as
     amended, of each Fund because of an affiliation with each Fund's investment
     adviser, AllianceBernstein L.P.
+    Member of the Audit Committee, the Governance and Nominating Committee and
     the Independent Directors Committee.
**   Member of the Fair Value Pricing Committee.

     During a Fund's fiscal year ended in 2005, the Board of Alliance National
Municipal met ten times and the Board of ACM Municipal Securities met ten times.
The Funds do not have a policy that requires a Director to attend annual
meetings of stockholders.

     Each Fund's Board has four standing committees: an Audit Committee, a
Governance and Nominating Committee, an Independent Directors Committee, and a
Fair Value Pricing Committee. The members of the Committees are identified above
in the table listing the Directors. The function of the Audit Committee of each
Fund is to assist the Board in its oversight of a Fund's financial reporting
process. The members of the Audit Committee are "independent" as required by
applicable listing standards of the New York Stock Exchange. During a Fund's
fiscal year ended in 2005, the Audit Committee of each of Alliance National
Municipal met eight times and of ACM Municipal Securities met eight times.
During a Fund's fiscal year ended in 2005, the Governance and Nominating
Committee of Alliance National Municipal met seven times and of ACM Municipal
Securities met seven times.

     Each Fund's Board of Directors has adopted a charter for its Governance and
Nominating Committee, a copy of which may be found on the Adviser's website,
http://www.alliancebernstein.com (click on Investor Solutions/Mutual
Funds/Closed-End). Pursuant to the charter of the Governance and Nominating
Committee, the Governance and Nominating Committee assists each Board in
carrying out its responsibilities with respect to governance of a Fund and
identifies, evaluates and selects and nominates candidates for that Board. The
Committee also may set standards or qualifications for Directors. The Committee
may consider candidates as Directors submitted by a Fund's current Board
members, officers, investment adviser, stockholders and other appropriate
sources.

     The Governance and Nominating Committee will consider candidates submitted
by a stockholder or group of stockholders who have owned at least 5% of a Fund's
outstanding common stock for at least two years at the time of submission and
who timely provide specified information about the candidates and the nominating
stockholder or group. To be timely for consideration by the Committee, the
submission, including all required information, must be submitted in writing to
the attention of the Secretary at the principal executive offices of a Fund not
less than 120 days before the date of the proxy statement for the previous
year's annual meeting of stockholders. The Committee will consider only one
candidate submitted by such a stockholder or group for nomination for election
at an annual meeting of stockholders. The Committee will not consider
self-nominated candidates.

     The Governance and Nominating Committee will consider and evaluate
candidates submitted by stockholders on the basis of the same criteria as those
used to consider and evaluate candidates submitted from other sources. These
criteria include the candidate's relevant knowledge, experience, and expertise,
the candidate's ability to carry out his or her duties in the best interests of
a Fund and the candidate's ability to qualify as a disinterested Director.

     The function of each Fund's Fair Value Pricing Committee is to consider, in
advance if possible, any fair valuation decision of the Adviser's Valuation
Committee relating to a security held by a Fund made under unique or highly
unusual circumstances not previously addressed by the Valuation Committee that
would result in a change in a Fund's NAV by more than $0.01 per share. The Fair
Value Pricing Committee did not meet during a Fund's most recently completed
fiscal year.

     The function of each Fund's Independent Directors Committee is to consider
and take action on matters that the Board or Committee believes should be
addressed in executive session of the disinterested Directors, such as review
and approval of the Advisory Agreements. During a Fund's fiscal year ended in
2005, the Independent Directors Committee of Alliance National Municipal met ten
times and of ACM Municipal Securities met ten times.

Adviser

     The Funds' investment adviser, AllianceBernstein L.P. (the "Adviser"), 1345
Avenue of the Americas, New York, NY 10105, is a leading international
investment adviser managing client accounts with assets as of September 30, 2006
totaling more than $659 billion (of which more than $82 billion represented the
assets of investment companies). As of September 30, 2006, the Adviser managed
retirement assets for many of the largest public and private employee benefit
plans (including 41 of the nations' FORTUNE 100 companies), for public employee
retirement funds in 37 states, for investment companies, and for foundations,
endowments, banks and insurance companies worldwide. The 44 registered
investment companies managed by the Adviser, comprising 125 separate investment
portfolios, currently have approximately 4.0 million stockholder accounts.

     The Adviser is a registered investment adviser under the Investment
Advisers Act of 1940, as amended. As of June 30, 2006, AllianceBernstein
Holding, L.P. ("Holding"), a Delaware limited partnership, owned approximately
32.7% of the issued and outstanding units of limited partnership interest in the
Adviser ("AllianceBernstein Units"). Units representing assignments of
beneficial ownership of limited partnership interests in Holding ("Holding
Units") trade publicly on the Exchange under the ticker symbol "AB".
AllianceBernstein Units do not trade publicly and are subject to significant
restrictions on transfer. AllianceBernstein Corporation ("AB Corp.") is the
general partner of both the Adviser and Holding. AB Corp. owns 100,000 general
partnership units in Holding and a 1% general partnership interest in the
Adviser. AB Corp. is an indirect wholly-owned subsidiary of AXA Financial, Inc.
("AXA Financial"), a Delaware corporation.

     As of June 30, 2006, AXA, AXA Financial, AXA Equitable Life Insurance
Company ("AXA Equitable") and certain subsidiaries of AXA Equitable beneficially
owned approximately 59.6% of the issued and outstanding AllianceBernstein Units
and approximately 1.7% of the issued and outstanding Holding Units that,
including the general partnership interests in the Adviser and Holding,
represent an economic interest of approximately 60.6% in the Adviser. As of June
30, 2006, SCB Partners, Inc., a wholly-owned subsidiary of SCB, Inc.,
beneficially owned approximately 6.3% of the issued and outstanding
AllianceBernstein Units.

     AXA, a French company, is the holding company for an international group of
companies and a worldwide leader in financial protection and wealth management.
AXA operates primarily in Western Europe, North America and the Asia/Pacific
region and, to a lesser extent, in other regions, including the Middle East,
Africa and South America. AXA has five operating business segments: life and
savings, property and casualty insurance, international insurance (including
reinsurance), asset management and other financial services. AXA Financial is a
wholly-owned subsidiary of AXA. AXA Equitable is an indirect wholly-owned
subsidiary of AXA Financial.

     Based on information provided by AXA, as of December 31, 2005,
approximately 14.30% of the issued ordinary shares (representing 23.19% of the
voting power) of AXA were owned directly and indirectly by three French mutual
insurance companies.

     The Advisory Agreements for Alliance National Municipal, and ACM Municipal
Securities were each approved on December 14, 2005. Each Fund's Advisory
Agreement was approved by the vote, cast in person, of the Fund's Directors
including the Directors who are not parties to the Advisory Agreement or
interested persons as defined in the 1940 Act, of any such party, at a meeting
called and held for that purpose.

     Under each Fund's advisory agreement with its Adviser (the "Advisory
Agreement") the Adviser provides office space, investment advisory services, and
order placement facilities for the Fund and pays all compensation of Directors
and officers of the Fund who are affiliated persons of the Adviser. The Adviser
or its affiliates also furnish a Fund, without charge, with management
supervision and assistance and office facilities, and provide persons
satisfactory to a Fund's Board to serve as the Fund's officers. Each Fund has,
under the Advisory Agreement, assumed obligation to pay for all other expenses.
As to the obtaining of services other than those specifically provided to a Fund
by the Adviser, the Fund may employ its own personnel. For such services, a Fund
may also utilize personnel employed by the Adviser or its affiliates and, in
such event, the services will be provided to a Fund at cost and the payments
therefore must be specifically approved by a Fund's Board.

     Under their Advisory Agreements, the Funds pay the Adviser the following
management fees:

     Alliance National Municipal's contractual management fee is 0.65% of its
average daily net assets. The management fee is calculated on the basis of net
assets including assets attributable to preferred stock accrued daily and
reflected in the net asset value of the common shares. The Adviser has
voluntarily agreed to waive a portion of Alliance National Municipal's
management fee or reimburse the Fund for expenses in the amount of 0.25% of the
Fund's average daily net assets until January 28, 2007 with the waiver
decreasing by 0.05% for each one year period commencing January 28 thereafter
with the full fee being payable commencing January 28, 2011 and beyond. However,
on November 20, 2006, the Adviser agreed, at the request of the Directors, to
place a cap on the amounts payable under the Advisory Agreement of 0.55% of
Alliance National Municipal's average daily net assets. The Adviser has also
agreed to request that the Board approve a new investment advisory contract
between the adviser and Alliance National Municipal that would make the maximum
fee of 0.55% permanent.

     ACM Municipal Securities: the Fund pays the Adviser an advisory fee at an
annual rate of .50 of 1% of the average weekly net assets of the Fund (i.e., the
average weekly value of the Fund's total assets, including assets attributable
to any preferred stock that may be outstanding, less the accrued liabilities of
the Fund). Such fee is accrued daily and paid monthly. The liquidation value of
any outstanding shares of preferred stock is not considered a liability of a
Fund for purposes of determining the average weekly net assets of the Fund.

     For the fiscal years ended October 31, 2005, 2004 and 2003, Alliance
National Municipal paid advisory fees to the Adviser that, in the aggregate,
amounted to $3,339,205, $3,294,746, and $3,268,527, respectively. For the fiscal
year ended October 31, 2005, 2004 and 2003, ACM Municipal Securities paid
advisory fees to the Adviser that, in the aggregate, amounted to $1,085,441,
$1,069,790, and $1,058,130, respectively.

     For purposes of the calculation of the fee payable to the Adviser, average
weekly net assets are determined on the basis of the average net assets of a
Fund for each weekly period (ending on Fridays) ending during the month. The net
assets for each weekly period are determined by averaging the net assets on
Friday of such weekly period with the net assets on Friday of the immediately
preceding weekly period. When a Friday is not a Fund business day, the
calculation will be based on the net assets of a Fund on the Fund business day
immediately preceding such Friday. This advisory fee may be greater than that
paid by most funds. In addition to payments to the Adviser under the Advisory
Agreement, a Fund pays certain other costs.

     As to the obtaining of services other than those specifically provided to a
Fund by the Adviser, a Fund may employ its own personnel. For such services, it
also may utilize personnel employed by the Adviser or by other subsidiaries of
Equitable. In such event, the services will be provided to a Fund at cost and
the payments specifically approved by a Fund's Board.

     Each Fund's Advisory Agreement is terminable with respect to that Fund
without penalty on 60 days' written notice by a vote of a majority of the
outstanding voting securities of such Fund or by a vote of a majority of a
Fund's Directors, or by the Adviser on 60 days' written notice, and will
automatically terminate in the event of its assignment. Each Fund's Advisory
Agreement provides that in the absence of willful misfeasance, bad faith or
gross negligence on the part of the Adviser, or of reckless disregard of its
obligations thereunder, the Adviser shall not be liable for any action or
failure to act in accordance with its duties thereunder.

     The Advisory Agreements for the Funds continue in effect from year to year,
provided that such continuance is specifically approved at least annually by a
vote of a majority of a Fund's outstanding voting securities or by a Fund's
Board, including in either case approval by a majority of the Directors who are
not parties to the Advisory Agreement or interested persons of such parties as
defined by the 1940 Act. Most recently, continuance of the Advisory Agreements
of the Funds was approved by the Board, including a majority of the Directors
who are not parties to the Advisory Agreements or interested persons of any such
party, at Meetings held on December 14, 2005.

Investment Professional Conflict of Interest Disclosure
-------------------------------------------------------

     As an investment adviser and fiduciary, the Adviser owes its clients and
stockholders an undivided duty of loyalty. We recognize that conflicts of
interest are inherent in our business and accordingly have developed policies
and procedures (including oversight monitoring) reasonably designed to detect,
manage and mitigate the effects of actual or potential conflicts of interest in
the area of employee personal trading, managing multiple accounts for multiple
clients, including AllianceBernstein Mutual Funds, and allocating investment
opportunities. Investment professionals, including portfolio managers and
research analysts, are subject to the above-mentioned policies and oversight
monitoring to ensure that all clients are treated equitably. We place the
interests of our clients first and expect all of our employees to meet their
fiduciary duties.

     Employee Personal Trading. The Adviser has adopted a Code of Business
Conduct and Ethics that is designed to detect and prevent conflicts of interest
when investment professionals and other personnel of the Adviser own, buy or
sell securities which may be owned by, or bought or sold for, clients. Personal
securities transactions by an employee may raise a potential conflict of
interest when an employee owns or trades in a security that is owned or
considered for purchase or sale by a client, or recommended for purchase or sale
by an employee to a client. Subject to the reporting requirements and other
limitations of its Code of Business Conduct and Ethics, the Adviser permits its
employees to engage in personal securities transactions, and also allows them to
acquire investments in the AllianceBernstein Mutual Funds through direct
purchase, 401K/profit sharing plan investment and/or notionally in connection
with deferred incentive compensation awards. The Adviser's Code of Ethics and
Business Conduct requires disclosure of all personal accounts and maintenance of
brokerage accounts with designated broker-dealers approved by the Adviser. The
Code also requires pre-clearance of all securities transactions and imposes a
one-year holding period for securities purchased by employees to discourage
short-term trading.

     Managing Multiple Accounts for Multiple Clients. The Adviser has compliance
policies and oversight monitoring in place to address conflicts of interest
relating to the management of multiple accounts for multiple clients. Conflicts
of interest may arise when an investment professional has responsibilities for
the investments of more than one account because the investment professional may
be unable to devote equal time and attention to each account. The investment
professional or investment professional teams for each client may have
responsibilities for managing all or a portion of the investments of multiple
accounts with a common investment strategy, including other registered
investment companies, unregistered investment vehicles, such as hedge funds,
pension plans, separate accounts, collective trusts and charitable foundations.
Among other things, the Adviser's policies and procedures provide for the prompt
dissemination to investment professionals of initial or changed investment
recommendations by analysts so that investment professionals are better able to
develop investment strategies for all accounts they manage. In addition,
investment decisions by investment professionals are reviewed for the purpose of
maintaining uniformity among similar accounts and ensuring that accounts are
treated equitably. No investment professional that manages client accounts
carrying performance fees is compensated directly or specifically for the
performance of those accounts. Investment professional compensation reflects a
broad contribution in multiple dimensions to long-term investment success for
our clients and is not tied specifically to the performance of any particular
client's account, nor is it directly tied to the level or change in level of
assets under management.

     Allocating Investment Opportunities. The Adviser has policies and
procedures intended to address conflicts of interest relating to the allocation
of investment opportunities. These policies and procedures are designed to
ensure that information relevant to investment decisions is disseminated
promptly within its portfolio management teams and investment opportunities are
allocated equitably among different clients. The investment professionals at the
Adviser routinely are required to select and allocate investment opportunities
among accounts. Portfolio holdings, position sizes, and industry and sector
exposures tend to be similar across similar accounts, which minimizes the
potential for conflicts of interest relating to the allocation of investment
opportunities. Nevertheless, investment opportunities may be allocated
differently among accounts due to the particular characteristics of an account,
such as size of the account, cash position, tax status, risk tolerance and
investment restrictions or for other reasons.

     The Adviser's procedures are also designed to prevent potential conflicts
of interest that may arise when the Adviser has a particular financial
incentive, such as a performance-based management fee, relating to an account.
An investment professional may perceive that he or she has an incentive to
devote more time to developing and analyzing investment strategies and
opportunities or allocating securities preferentially to accounts for which the
Adviser could share in investment gains.

     To address these conflicts of interest, the Adviser's policies and
procedures require, among other things, the prompt dissemination to investment
professionals of any initial or changed investment recommendations by analysts;
the aggregation of orders to facilitate best execution for all accounts; price
averaging for all aggregated orders; objective allocation for limited investment
opportunities (e.g., on a rotational basis) to ensure fair and equitable
allocation among accounts; and limitations on short sales of securities. These
procedures also require documentation and review of justifications for any
decisions to make investments only for select accounts or in a manner
disproportionate to the size of the account.

     Portfolio Manager Compensation

     The Adviser's compensation program for investment professionals is designed
to be competitive and effective in order to attract and retain the highest
caliber employees. The compensation program for investment professionals is
designed to reflect their ability to generate long-term investment success for
our clients, including stockholders of the AllianceBernstein Mutual Funds.
Investment professionals do not receive any direct compensation based upon the
investment returns of any individual client account, nor is compensation tied
directly to the level or change in level of assets under management. Investment
professionals' annual compensation is comprised of the following:

     (i) Fixed base salary: This is generally the smallest portion of
compensation. The base salary is a relatively low, fixed salary within a similar
range for all investment professionals. The base salary is determined at the
outset of employment based on level of experience, does not change significantly
from year-to-year and hence, is not particularly sensitive to performance.

     (ii) Discretionary incentive compensation in the form of an annual cash
bonus: The Adviser's overall profitability determines the total amount of
incentive compensation available to investment professionals. This portion of
compensation is determined subjectively based on qualitative and quantitative
factors. In evaluating this component of an investment professional's
compensation, the Adviser considers the contribution to his/her team or
discipline as it relates to that team's overall contribution to the long-term
investment success, business results and strategy of the Adviser. Quantitative
factors considered include, among other things, relative investment performance
(e.g., by comparison to competitor or peer group funds or similar styles of
investments, and appropriate, broad-based or specific market indices), and
consistency of performance. There are no specific formulas used to determine
this part of an investment professional's compensation and the compensation is
not tied to any pre-determined or specified level of performance. The Adviser
also considers qualitative factors such as the complexity and risk of investment
strategies involved in the style or type of assets managed by the investment
professional; success of marketing/business development efforts and client
servicing; seniority/length of service with the firm; management and supervisory
responsibilities; and fulfillment of the Adviser's leadership criteria.

     (iii) Discretionary incentive compensation in the form of awards under the
Adviser's Partners Compensation Plan ("deferred awards"): the Adviser's overall
profitability determines the total amount of deferred awards available to
investment professionals. The deferred awards are allocated among investment
professionals based on criteria similar to those used to determine the annual
cash bonus. There is no fixed formula for determining these amounts. Deferred
awards, for which there are various investment options, vest over a four-year
period and are generally forfeited if the employee resigns or the Adviser
terminates his/her employment. Investment options under the deferred awards plan
include many of the same AllianceBernstein Mutual Funds offered to mutual fund
investors, thereby creating a close alignment between the financial interests of
the investment professionals and those of the Adviser's clients and mutual fund
stockholders with respect to the performance of those mutual funds. The Adviser
also permits deferred award recipients to allocate up to 50% of their award to
investments in the Adviser's publicly traded equity securities.(1)

----------
(1)  Prior to 2002, investment professional compensation also included
     discretionary long-term incentive in the form of restricted grants of
     Alliance Capital's Master Limited Partnership Units.

     (iv) Contributions under the Adviser's Profit Sharing/401(k) Plan: The
contributions are based on the Adviser's overall profitability. The amount and
allocation of the contributions are determined at the sole discretion of
Adviser.

     The Adviser may act as an investment adviser to other persons, firms or
corporations, including investment companies, and is investment adviser to the
following registered investment companies: AllianceBernstein Balanced Shares,
Inc., AllianceBernstein Blended Style Series, Inc., AllianceBernstein Bond Fund,
Inc., AllianceBernstein Cap Fund, Inc., AllianceBernstein Corporate Shares,

Administrator

     The Adviser serves as administrator for the Funds and in that capacity
performs standard administrative services. The Adviser provides administrative
services to Alliance National Municipal under that Fund's Advisory Agreement and
performs administrative services for ACM Municipal Securities under an
Administration Agreement. The Administrator has engaged Prudential Mutual Fund
Management, Inc. (the "Sub-Administrator"), an indirect, wholly-owned subsidiary
of Prudential Financial, Inc., to act as sub-administrator. The
Sub-Administrator prepares financial and regulatory reports for the Funds and
provides other clerical services.

     Under the Administration Agreement, ACM Municipal Securities pays the fees
set forth below:

     ACM Municipal Securities: The Fund pays an administrative fee at an annual
rate of .15% of 1% of the Fund's average weekly net assets (determined in the
same manner as described above with respect to the Advisory Agreement).
Effective February 11, 2005, the Administrator has voluntarily agreed to
reimburse the Fund for administrative expenses at an annual rate of .10 of 1% of
the average weekly net assets of the Fund. For the services rendered to the
Administrator or the Fund and related expenses borne by the Sub-Administrator,
the Administrator from its own assets will pay the Sub-Administrator a monthly
fee at an annual rate of .10 of 1% of the average weekly net assets of the Fund
(determined in the same manner as described above with respect to the Advisory
Agreement). The fee paid by the Administrator to the Sub-Administrator will not
increase the expenses of the Fund. The Administration Agreement and the
Sub-Administration Agreement have been approved by the Fund's Board of
Directors.

     For the fiscal years ended October 31, 2005, 2004 and 2003, ACM Municipal
Securities paid administrative fees to the Adviser that, in the aggregate,
amounted to $325,633, $320,937, and $317,439, respectively, of which $156,635
was waived in 2005.

Stockholder Servicing

     AllianceBernstein Investor Services, Inc. ("ABIS"), an affiliate of the
Adviser, provides stockholder services for the Funds. The Funds reimburse ABIS
for these services. For these services and for the fiscal years ended October
31, 2005; October 31, 2004; and October 31, 2003, there was no reimbursement by
either Fund to ABIS.

Custodian

     Alliance National Municipal's securities and cash are held under a
Custodian Agreement by State Street Bank and Trust Company ("State Street"), One
Lincoln Street, Boston, MA 02111. ACM Municipal Securities' securities and cash
are held under a Custodian Agreement by The Bank of New York ("BONY"), One Wall
Street, New York, NY 10286. The Funds' assets are held under bank custodianship
in compliance with the 1940 Act.

     For these services and for the fiscal years ended October 31, 2005, October
31, 2004, and October 31, 2003, Alliance National Municipal paid BONY: $182,816,
$165,853, and $145,532, respectively. For these services and for the fiscal
years ended October 31, 2005, October 31, 2004, and October 31, 2003, ACM
Municipal Securities paid BONY: $102,673, $125,113, and $97,489, respectively.

Dividend Paying Agent, Transfer Agent and Registrar

     BONY serves as the dividend paying agent, transfer agent and registrar for
ACM Municipal Securities. Computershare Trust Company, N.A., P.O. Box 43010,
Providence, RI 02940-3011 will act as the dividend paying agent, transfer agent
and registrar for the common stock of each Fund. BONY is the Auction agent with
respect to each Fund's preferred stock and acts as transfer agent, registrar,
dividend disbursing agent, and redemption agent for such shares.

                             VALUATION OF PORTFOLIO SECURITIES

     Each Fund calculates and makes available for weekly publication the NAV of
its shares of common stock. The NAV per share of a Fund's common stock is
determined as of the close of trading on the NYSE each Friday or, when Friday is
not a Fund business day, on the immediately preceding Fund business day, by
adding the market value of all securities in a Fund's portfolio and other
assets, subtracting liabilities incurred or accrued, subtracting the aggregate
liquidation value of the outstanding shares of preferred stock, and dividing by
the total number of a Fund's shares of common stock then outstanding.

     In accordance with applicable rules under the 1940 Act, portfolio
securities are valued at current market value or at fair value as determined in
good faith by the Board of Directors. The Board of Directors has delegated to
the Adviser certain of the Board's duties with respect to the following
procedures. Readily marketable securities listed on the Exchange are valued,
except as indicated below, at the last sale price reflected on the consolidated
tape at the close of the Exchange on the business day as of which such value is
being determined. If there has been no sale on such day, the securities are
valued at the quoted bid prices on such day. If no bid prices are quoted on such
day, then the security is valued at the mean of the bid and asked prices at the
close of the Exchange on such day as obtained from one or more dealers regularly
making a market in such security. Where a bid and asked price can be obtained
from only one such dealer, such security is valued at the mean of the bid and
asked price obtained from such dealer unless it is determined that such price
does not represent current market value, in which case the security shall be
valued in good faith at fair value by, or pursuant to procedures established by,
the Board of Directors. Securities for which no bid and asked price quotations
are readily available are valued in good faith at fair value by, or in
accordance with procedures established by, the Board of Directors. Readily
marketable securities not listed on the Exchange are valued in like manner.
Portfolio securities traded on the Exchange and on one or more other national
securities exchange, and portfolio securities not traded on the Exchange but
traded on one or more other national securities exchange are valued in
accordance with these procedures by reference to the principal exchange on which
the securities are traded.

     Readily marketable securities traded only in the over-the-counter market
and debt securities listed on a U.S. national securities exchange whose primary
market is believed to be over-the-counter, are valued at the mean of the bid and
asked prices at the close of the Exchange on such day as obtained from two or
more dealers regularly making a market in such security. Where a bid and asked
price can be obtained from only one such dealer, such security is valued at the
mean of the bid and asked price obtained from such dealer unless it is
determined that such price does not represent current market value, in which
case the security shall be valued in good faith at fair value by, or in
accordance with procedures established by, the Board of Directors.

     Listed put and call options purchased by a Fund are valued at the last sale
price. If there has been no sale on that day, such securities will be valued at
the closing bid prices on that day.

     Open futures contracts and options thereon will be valued using the closing
settlement price or, in the absence of such a price, the most recent quoted bid
price. If there are no quotations available for the day of valuations, the last
available closing settlement price will be used.

     U.S. Government Securities and other debt instruments having 60 days or
less remaining until maturity are valued at amortized cost if their original
maturity was 60 days or less, or by amortizing their fair value as of the 61st
day prior to maturity if their original term to maturity exceeded 60 days
(unless in either case the Board of Directors determines that this method does
not represent fair value).

     Fixed-income securities may be valued on the basis of prices provided by a
pricing service when such prices are believed to reflect the fair market value
of such securities. The prices provided by a pricing service take into account
may factors, including institutional size trading in similar groups of
securities and any developments related to specific securities. Mortgage backed
and asset backed securities may be valued at prices obtained from a bond pricing
service or at a price obtained from one or more of the major broker/dealers in
such securities. In cases where broker/dealers quotes are obtained, the Adviser
may establish procedures whereby changes in market yields or spreads are used to
adjust, on a daily basis, a recently obtained quoted bid price on a security.

     All other assets of a Fund are valued in good faith at fair value by, or in
accordance with procedures established by, the Board of Directors.

     The Board of Directors may suspend the determination of a Fund's NAV
subject to the rules of the SEC and other governmental rules and regulations, at
a time when: (1) the Exchange is closed, other than customary weekend and
holiday closings, (2) an emergency exists whereby it is not reasonably
practicable for a Fund to dispose of securities owned by it or to determine
fairly the value of its net assets.

                           DIVIDEND REINVESTMENT PLAN

     Stockholders of ACM Municipal Securities whose common stock is registered
in their own names will automatically be enrolled as participants in that Fund's
Dividend Reinvestment and Cash Purchase Plan (the "DRIP"), under which dividends
and capital gain distributions to stockholders will be paid or reinvested in
additional shares of the Fund (the "Dividend Shares"). Procedures are available
to stockholders who do not wish to participate in the DRIP. Stockholders of
Alliance National Municipal whose common stock is registered in their own names
may elect to participate in that Fund's DRIP. Computershare Trust Company NA
("Agent") acts as agent to stockholders under the Plan. Stockholders whose
shares are held in the name of a broker or nominee should contact such broker or
nominee to determine whether or how they may participate in the DRIP. Assuming
the Acquisition is approved, the DRIP stockholders of ACM Municipal Securities
will automatically be enrolled in the DRIP for Alliance National Municipal.

     If the Board declares an income distribution or determines to make a
capital gains distribution payable either in shares or in cash, as holders of
the shares of common stock may have elected, non-participants in the DRIP will
receive cash and participants in the DRIP will receive the equivalent in shares
of common stock of a Fund valued as follows:

          (i)  If the shares of common stock are trading at NAV or at a premium
               above NAV at the time of valuation, the Fund will issue new
               shares at the greater of NAV or 95% of the then current market
               price.

          (ii) If the shares of common stock are trading at a discount from NAV
               at the time of valuation, the Agent will receive the dividend or
               distribution in cash and apply it to the purchase of the Fund's
               shares of common stock in the open market on the NYSE or
               elsewhere, for the participants' accounts. Such purchase will be
               made on or shortly after the payment date for such dividend or
               distribution and in no event more than 30 days after such date
               except where temporary curtailment or suspension of purchase is
               necessary to comply with Federal securities laws. If, before the
               Agent has completed its purchases, the market price exceeds the
               NAV of a share of common stock, the average purchase price per
               share paid by the Agent may exceed the NAV of the Fund's shares
               of common stock, resulting in the acquisition of fewer shares
               than if the dividend or distribution had been in shares issued by
               the Fund.

     The Agent will maintain all stockholder's accounts in the DRIP and furnish
written confirmation of all transactions in the account, including information
needed by stockholders for tax records. Shares in the account of each DRIP
participant will be held by the Agent in non-certificate form in the name of the
participant, and each stockholder's proxy will include those shares purchased or
received pursuant to the DRIP.

     There will be no charges with respect to shares issued directly by a Fund
to satisfy the dividend reinvestment requirements. However, each participant
will pay a pro rata share of brokerage commissions incurred with respect to the
Agent's open market purchases of shares. In each case, the cost per share of
shares purchased for each stockholder's account will be the average cost,
including brokerage commissions, of any share purchased in the open market plus
the cost of any shares issued by a Fund.

     The automatic reinvestment of dividends and distributions will not relieve
participants of any income taxes that may be payable (or required to be
withheld) on dividends and distributions.

     Experience under the DRIP may indicate that changes are desirable.
Accordingly, a Fund reserves the right to amend or terminate the DRIP as applied
to any voluntary cash payments made and any dividend or distribution paid
subsequent to written notice of the change sent to participants at least 90 days
before the record date for such dividend or distribution. The DRIP may also be
amended or terminated by the Agent on at least 90 days' written notice to
participants in the DRIP. All correspondence concerning the DRIP should be
directed Computershare Trust Company N.A., P.O. Box 43010, Providence, RI
02940-3011.

                    DESCRIPTION OF COMMON AND PREFERRED STOCK

Shares of Common Stock of the Funds

     Alliance National Municipal is authorized to issue 1,999,992,200 shares of
common stock at $.001 par value. ACM Municipal Securities is authorized to issue
99,996,400 shares of common stock at $.01 par value. There are no
subscription/preemptive or exchange rights under the charters. Each share of a
Fund's common stock has equal voting, dividend, distribution and liquidation
rights subject to the preferential rights of a Fund's preferred stock. At any
time when a Fund's preferred stock are outstanding, common stockholders will not
be entitled to receive any distributions from a Fund unless all accrued
dividends on preferred stock have been paid, and unless asset coverage (as
defined in the 1940 Act) with respect to the preferred stock would be at least
200% after giving effect to such distributions. Shares of common stock when
issued are duly authorized, fully paid and nonassessable. Under the rules of the
NYSE applicable to listed companies, each Fund is required to hold an annual
meeting of stockholders each year.

     Holders of common stock are entitled to one vote per share. All voting
rights for the election of directors are non-cumulative, which means that the
holders of more than 50% of the shares of common stock of a Fund can elect 100%
of the directors then nominated for election if they choose to do so and, in
such event, the holders of the remaining shares of common stock will not be able
to elect any directors.

     Each Fund intends to distribute monthly its net investment income to
holders of its common stock. Monthly distributions to common stockholders will
consist of net investment income remaining after the payment of dividends on
outstanding preferred stock. Net capital gains, if any, will be distributed at
least annually to common stockholders to the extent such net capital gains are
not necessary to satisfy the dividend, redemption or liquidation preferences of
any preferred stock. For tax purposes, a Fund will be required, assuming
issuance of preferred stock, to allocate net capital gain and other taxable
income, if any, between common stock and preferred stock in proportion to total
dividends paid to each class for the year in which such net capital gain or
other taxable income is realized. While any preferred stock is outstanding, a
Fund may not declare any cash dividend or other distribution on its common
stock, unless, at the time of such declaration, (a) all accrued preferred stock
dividends have been paid and (b) the NAV of the Fund's portfolio (determined
after deducting the amount of such dividend or other distribution) is at least
200% of the liquidation value of the outstanding preferred stock (expected to
equal the original purchase price per share plus any accrued and unpaid
dividends thereon). This limitation on a Fund's ability to make distributions on
its common stock could under certain circumstances impair the ability of the
Fund to maintain its qualification for taxation as a regulated investment
company.

Shares of Preferred Stock of the Funds

     Alliance National Municipal has authorized, issued and outstanding 7,800
shares of Auction Preferred Stock as follows: 1,950 Series M Preferred Shares,
1,950 Series T Preferred Shares, 1,950 Series W Preferred Shares and 1,950
Series TH Preferred Shares. The preferred shares have a liquidation value of
$25,000 per share plus accumulated unpaid dividends. Alliance National
Municipal's preferred stock will pay dividends based on a rate set at Auctions,
normally held weekly, except in the case of special rate periods. For Series M
Preferred Shares, Series T Preferred Shares, Series W Preferred Shares and
Series TH Preferred Shares auctions are held respectively, on Mondays, Tuesdays,
Wednesdays and Thursdays. Dividends are payable, when, as and if authorized by
the Board and declared by the Fund: on Series M Preferred Shares on Tuesdays; on
Series T Preferred Shares on Wednesdays; on Series W Preferred Shares on
Thursdays and on Series TH Preferred Shares on Fridays.

     ACM Municipal Securities has authorized, issued and outstanding 3,600
shares of Auction Preferred Stock as follows: 1,200 Series A Preferred Shares,
1,200 Series B Preferred Shares and 1,200 Series C Preferred Shares. The
preferred shares have a liquidation value of $25,000 per share plus accumulated
unpaid dividends. ACM Municipal Securities' preferred shares will pay dividends
based on a rate set at Auctions, normally held weekly, except in the case of
special rate periods. For Series A Preferred Shares, Series B Preferred Shares,
and Series C Preferred Shares auctions are held, respectively, on Wednesdays,
Mondays, and Thursdays. Dividends are payable, when, as and if authorized by the
Board and declared by the Fund: on Series A Preferred Shares on Thursdays; on
Series B Preferred Shares on Tuesdays; and on Series C Preferred Shares on
Fridays.

     If dividends are payable on a day that is not a business day then such
dividends will be paid on such shares on the first business day that falls after
that day.

     Each series of preferred stock of a Fund will rank on parity with any other
series of preferred stock of that Fund as to the payment of dividends and the
distribution of assets upon liquidation. Preferred stock is, when issued, fully
paid and, subject to matters discussed in a Fund's Articles of Supplementary,
non-assessable and have no preemptive or conversion rights or rights to
cumulative voting.

     Except as otherwise provided in a Fund's Charter or as otherwise required
by law, preferred stockholders will have equal voting rights with common
stockholders (one vote per share) and will vote together with common
stockholders and any other preferred stockholders as a single class. The Firm's
charter sets forth matters on which a Fund's preferred stockholders will vote
separately as a single class.

     In connection with the election of a Fund's Directors, holders of
outstanding preferred stock, voting as a separate class, are entitled to elect
two of a Fund's Directors, and the remaining Directors are elected by common
stockholders and preferred stockholders, voting together as a single class. The
Funds' Charters sets forth circumstances relating to outstanding and unpaid
dividends due to preferred stockholders that would entitle such stockholders to
elect members to the Board that would result in such stockholders having elected
a majority of the Directors to the Board.

     (i)  Redemptions

     The redemption provisions pertaining to the preferred stock of each Fund
are similar. It is anticipated that preferred stock of each Fund will generally
be redeemable at the option of the applicable Fund at a price equal to the
liquidation preference of each ($25,000 per share), plus accumulated but unpaid
dividends (whether or not earned or declared) to the date of redemption plus, in
certain circumstances, a redemption premium. Preferred stock of each Fund is
also subject to mandatory redemption at a price equal to their liquidation
preference plus accumulated but unpaid dividends (whether or not earned or
declared) to the date of redemption upon the occurrence of certain specified
events, such as the failure of a Fund to maintain asset coverage requirements
for its preferred stock specified by Moody's and S&P in connection with their
issuance of ratings on their preferred stock.

     (ii) Liquidation

     Subject to the rights of holders of any series or class or classes of
shares ranking on parity with a Fund's preferred stock with respect to the
distribution of assets upon liquidation of a Fund, upon liquidation of a Fund,
whether voluntary or involuntary, the holders of preferred stock then
outstanding will be entitled to receive and be paid out of the assets of a Fund
available for distribution to its stockholders, before any payment or
distribution shall be made on the common stock or on any other class of stock of
a Fund ranking junior to the preferred stock, an amount equal to the liquidation
preference with respect to such shares, plus an amount equal to all dividends
thereon (whether or not earned or declared) accumulated but unpaid to (but not
including) the date of final distribution in same-day funds, together with any
applicable gross-up payments (i.e., to account for certain federal income tax
liability consequences) in connection with the liquidation of a Fund. After the
payment to the holders of preferred stock of the full preferential amounts
provided for as described herein, the holders of preferred stock shall have no
right or claim to any of the remaining assets of a Fund.

     Neither the sale of all or substantially all the property or business of a
Fund, nor the merger or consolidation of a Fund into or with any other
corporation nor the merger or consolidation of any other corporation into or
with a Fund, shall be a liquidation, whether voluntary or involuntary, for the
purposes of the foregoing paragraph.

     (iii) Ratings

     The preferred stock of each Fund has been assigned a rating of "AAA" from
S&P and "Aaa" from Moody's. Each Fund intends that, so long as its preferred
stock are outstanding, the composition of its portfolio will reflect guidelines
established by S&P and Moody's in connection with each Fund's receipt of a
rating for such shares of at least "AAA" from S&P and "Aaa" from Moody's. S&P
and Moody's, which are nationally recognized statistical rating organizations,
issue ratings for various securities reflecting the perceived creditworthiness
of such securities. The guidelines for rating such preferred stock have been
developed by S&P and Moody's and are designed to ensure that assets underlying
outstanding debt or preferred stock will be varied sufficiently and will be of
sufficient quality and amount to justify investment grade ratings. The
guidelines do not have the force of law but have been adopted by each Fund in
order to satisfy current requirements necessary for S&P and Moody's to issue the
above-described ratings for preferred stock, which ratings generally are relied
upon by institutional investors in purchasing such securities. The guidelines
provide a set of tests for portfolio composition and asset coverage that
supplement (and in some cases are more restrictive than) the applicable
requirements under the 1940 Act.

     Each Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by S&P or Moody's. Failure to adopt
any such modifications, however, may result in a change in the ratings described
above or a withdrawal of the ratings altogether. In addition, any rating agency
providing a rating for a Fund's preferred stock, may, at any time, change or
withdraw any such rating. As set forth in the Articles of Supplementary, each
Fund, without stockholder approval, may modify certain definitions or
restrictions that have been adopted by a Fund pursuant to the rating agency
guidelines, provided the Board of a Fund has obtained written confirmation from
S&P and Moody's that any such change would not impair the ratings then assigned
by S&P and Moody's to the preferred stock.

     Each Fund is required under the 1940 Act and Moody's and S&P guidelines to
maintain assets having in the aggregate a Discounted Value at least equal to the
preferred stock Basic Maintenance Amount. Moody's and S&P have each established
separate guidelines for determining Discounted Value. To the extent any
particular portfolio holding does not satisfy the applicable rating agency's
guidelines, all or a portion of such holding's value will not be included in the
calculation of Discounted Value (as defined by such rating agency). The Moody's
and S&P guidelines do not impose any limitations on the percentage of a Fund's
assets that may be invested in holdings not eligible for inclusion in the
calculation of the Discounted Value of a Fund's portfolio. The amount of such
assets included in the portfolio at any time may vary depending upon the rating,
diversification and other characteristics of the eligible assets included in the
portfolio, although it is not anticipated that in the normal course of business
the value of such assets would exceed 20% of each Fund's total assets. The
preferred stock Basic Maintenance Amount includes, among other things, the sum
of (a) the aggregate liquidation preference of preferred stock then outstanding
and (b) certain accrued and projected payment obligations of a Fund.

     Each Fund is also required under the 1940 Act and rating agency guidelines
to maintain, with respect to preferred stock, as of the last Business Day of
each month in which any such shares are outstanding, asset coverage of at least
200% with respect to senior securities that are shares, including preferred
stock (or such other asset coverage as may in the future be specified in or
under the 1940 Act as the minimum asset coverage for senior securities that are
shares of a closed-end investment company as a condition of declaring dividends
on its common stock or 1940 Act preferred stock asset coverage).

     In the event each Fund does not timely cure a failure to maintain (a) a
Discounted Value of its portfolio equal to the preferred shares basic
maintenance amount or (b) the 1940 Act preferred stock asset coverage, in each
case in accordance with the requirements of the rating agency or agencies then
rating the preferred stock, a Fund will be required to redeem preferred stock as
described under "Redemption--Mandatory Redemption" above.

     Each Fund may, but is not required to, adopt any modifications to the
guidelines that may hereafter be established by Moody's or S&P. Failure to adopt
any such modifications, however, may result in a change in the ratings described
above or a withdrawal of ratings altogether. In addition, any rating agency
providing a rating for the preferred stock may, at any time, change or withdraw
any such rating. The Board may in its sole discretion modify the definitions and
related provisions that have been adopted by each Fund pursuant to the rating
agency guidelines if necessary or appropriate with respect to the preferred
stock if each Fund receives written confirmation from Moody's or S&P, or both,
as appropriate, that any such modification would not impair the ratings then
assigned by Moody's and S&P to the preferred stock.

     As recently described by Moody's and S&P, a preferred stock rating is an
assessment of the capacity and willingness of an issuer to pay preferred stock
obligations. The ratings on the preferred stock are not recommendations to
purchase, hold or sell those shares, inasmuch as the ratings do not comment as
to market price or suitability for a particular investor. The rating agency
guidelines described above also do not address the likelihood that an owner of
preferred stock will be able to sell such shares in an Auction or otherwise. The
ratings are based on current information furnished to Moody's and S&P by a Fund
and the Adviser and information obtained from other sources. The ratings may be
changed, suspended or withdrawn as a result of changes in, or the unavailability
of, such information. The common stock has not been rated by an NRSRO.

     A rating agency's guidelines will apply to the preferred stock only so long
as such rating agency is rating such shares. Each Fund will pay certain fees to
Moody's or S&P, or both, for rating the preferred stock.

     Board of Directors
     ------------------

     Each Fund has a Board of Directors that is divided into three classes of
Directors. The terms of the Directors in a class are staggered so that for a
given year only one class of Directors will be up for election by a Fund's
stockholders. The Funds believe that classification of the Board of Directors
will help to assure the continuity and stability of a Fund's business strategies
and policies as determined by the Board of Directors.

     The classified board provision could have the effect of making the
replacement of incumbent Directors more time-consuming and difficult. At least
two annual meetings of stockholders, instead of one, will generally be required
to effect a change in a majority of the Board of Directors. Thus, the classified
board provision could increase the likelihood that incumbent Directors will
retain their positions. The staggered terms of Directors may delay, defer, or
prevent a tender offer or an attempt to change control of a Fund, although the
tender offer or change in control might be in the best interest of the
stockholders.

     The procedures available to a Fund's stockholders for calling stockholders'
meetings for the removal of directors are the same. Under Maryland law and the
Funds' charters, a director may be removed only with cause at a meeting duly
called and at which a quorum is present by the affirmative vote of seventy-five
percent of all the votes entitled to be cast.

Stockholder Meetings
--------------------

     Special meetings of stockholders for any purpose may be called by a Fund's
Secretary upon the written request of holders of shares entitled to cast not
less than a majority of the votes entitled to be cast at a meeting.

     Except as otherwise required by law or a Fund's charter, the presence in
person or by proxy of the holders of a majority of the shares entitled to be
cast constitutes a quorum at any meeting of stockholders of a Fund. Pursuant to
each Fund's charter, except in instances involving extraordinary corporate
action, such as in a merger, making amendments to its Charter or removal of a
director, generally, the vote of a majority of the aggregate number of votes
entitled to be cast on a matter is required in order to take or authorize any
such action for which approval of the stockholders is sought. The By-Laws of
each Fund provides that each director shall be elected by the affirmative vote
of the holders of a majority of the votes entitled to be cast; for other
matters, when a quorum is present, the affirmative vote of a majority of the
votes cast shall decide any question brought before such meeting unless a
statute or charter requires a higher voting margin.

The Auction
-----------

     General. The Articles provide that, except as otherwise described herein,
the Applicable Rate for the shares of each series of preferred stock, for each
Rate Period of shares of such series after the Initial Rate Period thereof,
shall be equal to the rate per annum that the Auction Agent advises has resulted
on the Business Day preceding the first day of such Subsequent Rate Period (an
"Auction Date") from implementation of the auction procedures (the "Auction
Procedures"), in which persons determine to hold or offer to sell or, based on
dividend rates bid by them, offer to purchase or sell shares of such series.
Each periodic implementation of the Auction Procedures is referred to herein as
an Auction. See the Articles for a more complete description of the Auction
process.

     Auction Agency Agreement. Each Fund has entered into an Auction Agency
Agreement with the Auction Agent that provides, among other things, that the
Auction Agent will follow the Auction Procedures for purposes of determining the
Applicable Rate for each series of preferred stock so long as the Applicable
Rate for shares of such series is to be based on the results of an Auction. Each
Fund will pay the Auction Agent compensation for its services under the Auction
Agency Agreement.

     The Auction Agent may terminate the Auction Agency Agreement upon notice to
a Fund on a date no earlier than 45 days after such notice, except that if the
Auction Agent has not received amounts due to it under the terms of the Auction
Agency Agreement, the Auction Agent may terminate on a date 30 days after
delivering to a Fund notice of its failure to receive such amounts. If the
Auction Agent should resign, a Fund will use its best efforts to enter into an
agreement with a successor Auction Agent containing substantially the same terms
and conditions as the Auction Agency Agreement. A Fund may remove the Auction
Agent provided that prior to such removal a Fund shall have entered into such an
agreement with a successor Auction Agent.

     Broker-Dealer Agreements. Each Auction requires the participation of one or
more Broker-Dealers. The Auction Agent has entered into agreements
(collectively, the "Broker-Dealer Agreements") with several Broker-Dealers
selected by a Fund, which provide for the participation of those Broker-Dealers
in Auctions for preferred stock.

     The Auction Agent after each Auction for preferred stock will pay from
funds provided by each Fund a service charge to each Broker-Dealer on the basis
of the purchase price of the preferred stock placed by the Broker-Dealer at the
Auction. The service charge will be paid at the annual rate of .25% in the case
of any Minimum Rate Period or a Rate Period of less than one year, or a
percentage agreed to by a Fund and the Broker-Dealers in the case of any Auction
for a Rate Period of one year or longer. For the purposes of the preceding
sentence, preferred stock will be placed by a Broker-Dealer if such shares were
(a) the subject of Hold Orders deemed to have been submitted to the Auction
Agent by the Broker-Dealer and were acquired by such Broker-Dealer for its own
account or were acquired by such Broker-Dealer for its customers who are
Beneficial Owners or (b) the subject of an Order submitted by such Broker-Dealer
that is (i) a Submitted Bid of an Existing Holder that resulted in such Existing
Holder continuing to hold such shares as a result of the Auction or (ii) a
Submitted Bid of a Potential Holder that resulted in such Potential Holder
purchasing such shares as a result of the Auction or (iii) a valid Hold Order.

     Each Fund may request the Auction Agent to terminate one or more
Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer
Agreement is in effect after such termination.

Auction Procedures
------------------

     Prior to the Submission Deadline on each Auction Date for a series of
Preferred Shares, each customer of a Broker-Dealer who is listed on the records
of that Broker-Dealer (or, if applicable, the Auction Agent) as holder of shares
of the series, or a Beneficial Owner, may submit Orders with respect to shares
of such series to that Broker-Dealer as follows:

     o    Hold Order--indicating its desire to hold shares of the series without
          regard to the Applicable Rate for shares of the series for the next
          Rate Period thereof.

     o    Bid--indicating its desire to sell shares of the series at $25,000 per
          share if the Applicable Rate for the shares for the next Rate Period
          thereof is less than the rate specified in such Bid (also known as a
          hold-at-a-rate order).

     o    Sell Order--indicating its desire to sell shares of the series at
          $25,000 per share without regard to the Applicable Rate for shares of
          such series for the next Rate Period thereof.

     A Beneficial Owner may submit different types of Orders to its
Broker-Dealer with respect to a series of preferred stock then held by such
Beneficial Owner. A Beneficial Owner of shares of such series that submits a Bid
with respect to shares of such series to its Broker-Dealer having a rate higher
than the Maximum Rate for shares of such series on the Auction Date therefore
will be treated as having submitted a Sell Order with respect to such shares to
its Broker-Dealer. A Beneficial Owner of shares of such series that fails to
submit an Order with respect to such shares to its Broker-Dealer will be deemed
to have submitted a Hold Order with respect to such shares of such series to its
Broker-Dealer; provided, however, that if a Beneficial Owner of shares of such
series fails to submit an Order with respect to shares of such series to its
Broker-Dealer for an Auction relating to a Rate Period of more than 28 Rate
Period Days, such Beneficial Owner will be deemed to have submitted a Sell Order
with respect to such shares to its Broker-Dealer. A Sell Order shall constitute
an irrevocable offer to sell the preferred stock subject thereto. A Beneficial
Owner that offers to become the Beneficial Owner of additional preferred stock
is, for purposes of such offer, a Potential Beneficial Owner as discussed below.

     A customer of a Broker-Dealer that is not a Beneficial Owner of a series of
preferred stock but that wishes to purchase shares of such series, or that is a
Beneficial Owner of shares of such series that wishes to purchase additional
shares of such series (in each case, a "Potential Beneficial Owner"), may submit
Bids to its Broker-Dealer in which it offers to purchase shares of such series
at $25,000 per share if the Applicable Rate for shares of such series for the
next Rate Period thereof is not less than the rate specified in such Bid. A Bid
placed by a Potential Benefit Owner of shares of such series specifying a rate
higher than the Maximum Rate for shares of such series on the Auction Date
therefore will not be accepted.

     The Broker-Dealers in turn will submit the Orders of their respective
customers who are Beneficial Owners and Potential Beneficial Owners to the
Auction Agent, designating themselves (unless otherwise permitted by a Fund) as
Existing Holders in respect of shares subject to Orders submitted or deemed
submitted to them by Beneficial Owners and as Potential Holders in respect of
shares subject to Orders submitted to them by Potential Beneficial Owners.
However, neither a Fund nor the Auction Agent will be responsible for a
Broker-Dealer's failure to comply with the foregoing. Any Order placed with the
Auction Agent by a Broker-Dealer as or on behalf of an Existing Holder or a
Potential Holder will be treated in the same manner as an Order placed with a
Broker-Dealer by a Beneficial Owner or Potential Beneficial Owner. Similarly,
any failure by a Broker-Dealer to submit to the Auction Agent an Order in
respect of any preferred stock held by it or customers who are Beneficial Owners
will be treated in the same manner as a Beneficial Owner's failure to submit to
its Broker-Dealer an Order in respect of preferred stock held by it. A
Broker-Dealer may also submit Orders to the Auction Agent for its own account as
an Existing Holder or Potential Holder, provided it is not an affiliate of a
Fund.

     If Sufficient Clearing Bids for a series of preferred stock exist (that is,
the number of shares of such series subject to Bids submitted or deemed
submitted to the Auction Agent by Broker-Dealers as or on behalf of Potential
Holders with rates equal to or lower than the Maximum Rate for shares of such
series is at least equal to the number of shares of such series subject to Sell
Orders submitted or deemed submitted to the Auction Agent by Broker-Dealers as
or on behalf of Existing Holders), the Applicable Rate for shares of such series
for the next succeeding Rate Period thereof will be the lowest rate specified in
the Submitted Bids which, taking into account such rate and all lower rates bid
by Broker-Dealers as or on behalf of Existing Holders and Potential Holders,
would result in Existing Holders and Potential Holders owning the shares of such
series available for purchase in the Auction. If Sufficient Clearing Bids for a
series of preferred stock do not exist, the Applicable Rate for shares of such
series for the next succeeding Rate Period thereof will be the Maximum Rate for
shares of such series on the Auction Date therefor. In such event, Beneficial
Owners of shares of such series that have submitted or are deemed to have
submitted Sell Orders may not be able to sell in such Auction all shares of such
series subject to such Sell Orders. If Broker-Dealers submit or are deemed to
have submitted to the Auction Agent Hold Orders with respect to all Existing
Holders of a series of preferred stock, the Applicable Rate for shares of such
series for the next succeeding Rate Period thereof will be the All Hold Order
Rate.

     The Auction Procedures include a pro rata allocation of shares for purchase
and sale, which may result in an Existing Holder continuing to hold or selling,
or a Potential Holder purchasing, a number of a series of preferred stock that
is fewer than the number of shares of such series specified in its Order. To the
extent the allocation procedures have that result, Broker-Dealers that have
designated themselves as Existing Holders or Potential Holders in respect of
customer Orders will be required to make appropriate pro rata allocations among
their respective customers.

     Settlement of purchases and sales will be made on the next Business Day
(also a Dividend Payment Date) after the Auction Date through the Securities
Depository. Purchasers will make payment through their Agent Members in the
same-day funds to the Securities Depository against delivery to their respective
Agent Members. The Securities Depository will make payment to the sellers' Agent
Members in accordance with the Securities Depository's normal procedures, which
now provide for payment against delivery by their Agent Members in same-day
funds.

     The Auction for Series M Preferred Shares will normally be held every
Monday, and each Subsequent Rate Period of shares of such series will normally
begin on the following Tuesday. The Auction for Series T Preferred Shares will
normally be held every Tuesday, and each Subsequent Rate Period of shares of
such series will normally begin on the following Wednesday. The Auction for
Series W Preferred Shares will normally be held every Wednesday, and each
Subsequent Rate Period of shares of such series will normally begin on the
following Thursday. The Auction for Series TH Preferred Shares will normally be
held every Thursday, and each Subsequent Rate Period of shares of such series
will normally begin on the following Friday.

     Whenever a Fund intends to include any net capital gain or other income
taxable for regular federal income tax purposes in any dividend on preferred
stock, a Fund shall, in the case of Minimum Rate Periods or Special Rate Periods
of 28 Rate Period Days or fewer, and may, in the case of any other Special Rate
Period, notify the Auction Agent of the amount to be so included not later than
the Dividend Payment Date next preceding the Auction Date on which the
Applicable Rate for such dividend is to be established. Whenever the Auction
Agent receives such notice from a Fund, it will be required in turn to notify
each Broker-Dealer, who, on or prior to such Auction Date, in accordance with
its Broker-Dealer Agreement, will be required to notify its customers who are
Beneficial Owners and Potential Beneficial Owners believed by it to be
interested in submitting an Order in the Auction to be held on such Auction
Date.

Secondary Trading Market and Transfer of Preferred Stock
--------------------------------------------------------

     The Broker-Dealers are expected to maintain a secondary trading market in
preferred stock outside of Auctions, but are not obligated to do so, and may
discontinue such activity at any time. There can be no assurance that such
secondary trading market in preferred stock will provide owners with liquidity
of investment. The preferred stock is not registered on any stock exchange or on
the NASDAQ Stock Market. Investors who purchase shares in an Auction for a
Special Rate Period should note that because the dividend rate on such shares
will be fixed for the length of such Rate Period, the value of the shares may
fluctuate in response to changes in interest rates, and may be more or less than
their original cost if sold on the open market in advance of the next Auction
therefor, depending upon market conditions.

     A Beneficial Owner or an Existing Holder may sell, transfer or otherwise
dispose of preferred stock only in whole shares and only (1) pursuant to a Bid
or Sell Order placed with the Auction Agent in accordance with the Auction
Procedures, (2) to a Broker-Dealer or (3) to such other persons as may be
permitted by a Fund; provided, however, that (a) a sale, transfer or other
disposition of preferred stock from a customer of a Broker-Dealer who is listed
on the records of that Broker-Dealer as the holder of such shares to that
Broker-Dealer or another customer of that Broker-Dealer shall not be deemed to
be a sale, transfer or other disposition for purposes of the foregoing if such
Broker-Dealer remains the Existing Holder of the shares so sold, transferred or
disposed of immediately after such sale, transfer or disposition and (b) in the
case of all transfers other than pursuant to Auctions, the Broker-Dealer (or
other person, if permitted by a Fund) to whom such transfer is made shall advise
the Auction Agent of such transfer.

Certain Anti-Takeover Provisions of the Funds' Charters and By-Laws

     The Funds presently have provisions in their Charters and By-Laws
(together, the "Charter Documents") that are intended to limit (i) the ability
of other entities or persons to acquired control of a Fund, (ii) a Fund's
freedom to engage in certain transactions, or (iii) the ability of a Fund's
Directors or stockholders to amend the Charter Documents or effect changes in a
Fund's management. These provisions of the Charter Documents may be regarded as
"anti-takeover" provisions.

     The Board of Directors of each Fund is divided into three classes, each
having a term of three years. At each annual meeting of stockholders, the term
of one class of Directors expires. Accordingly, only those Directors in one
class maybe changed in any one year, and it would require two years to change a
majority of the Board of Directors (although under Maryland law procedures are
available for the removal of Directors even if they are not then standing for
reelections and under SEC regulations procedures are available for including
stockholders proposals in management's annual proxy statement). Such a system of
electing Directors may have the effect of maintaining the continuity of
management and, thus, make it more difficult for a Fund's stockholders to change
the majority of Directors. Generally under a Fund's Charter, the affirmative
vote of the holders of a majority of the votes entitled to be cast is required
for the consolidation of the Fund with another corporation, a merger of the Fund
with or into another corporation (except for certain mergers in which the Fund
is the successor), a statutory share exchange in which the Fund is not the
successor, a sale or transfer of all or substantially all of the Fund's assets,
the dissolution of the Fund and amendment to the Fund's Charter. In addition,
the affirmative vote of 75% (which is higher than that required under Maryland
law or the 1940 Act) of the outstanding shares of common stock of a Fund is
required generally to authorize any of the following transactions or to amend
the provisions of the Charter relating to such transactions:

          (i)  merger, consolidation or statutory share exchange of the Fund
               with or into any other corporation;

          (ii) issuance of any securities of the Fund to any person or entity
               for cash;

         (iii) sale, lease, or exchange of all or any substantial part of the
               assets of the Fund to any entity or person (except assets having
               an aggregate fair market value of less than $1,000,000); or

          (iv) sale, lease, or exchange to the Fund, in exchange for securities
               of the Fund, of any assets of any entity or person (except assets
               having an aggregate fair market value of less than $1,000,000);

if such corporation, person or entity is directly, or indirectly through
affiliates, the beneficial owner of more than 5% of the outstanding shares of
the Fund (a "principal stockholder"). However, such vote would not be required
where, under certain conditions, the Board of Directors approves the
transaction, although in certain cases involving merger, consolidation or
statutory share exchange, or sale of all or substantially all of a Fund's
assets, the affirmative vote of a majority of the outstanding shares of the Fund
would nevertheless be required.

     The provisions of the Charter Documents described above and a Fund's right
to repurchase or make a tender offer for its common stock could have the effect
of depriving the owners of shares of opportunities to sell their shares at a
premium over prevailing market prices, by discouraging a third party from
seeking to obtain control of a Fund in a tender offer or similar transaction.
The overall effect of these provisions is to render more difficult the
accomplishment of a merger or the assumption of control by a principal
stockholder. However, they provide the advantage of potentially requiring
persons seeking control of a Fund to negotiate with its management regarding the
price to be paid and facilitating the continuity of a Fund's management and
investment objective and policies. The Board of Directors of each Fund has
considered the foregoing anti-takeover provisions and concluded that they are in
the best interests of a Fund and its stockholders.

                             PORTFOLIO TRANSACTIONS

     Subject to the general supervision of a Fund's Board, the Adviser is
responsible for the investment decisions and the placing of orders for portfolio
transactions for a Fund. A Fund's portfolio transactions occur primarily with
issuers, underwriters or major dealers acting as principals. Such transactions
are normally on a net basis, which does not involve payment of brokerage
commissions. The cost of securities purchased from an underwriter usually
includes a commission paid by the issuer to the underwriters; transactions with
dealers normally reflect the spread between bid and asked prices. Premiums are
paid with respect to options purchased by a Fund and brokerage commissions are
payable with respect to transactions in exchange-traded futures contracts.

     A Fund has no obligation to enter into transactions in portfolio securities
with any dealer, issuer, underwriter or other entity. In placing orders, it is
the policy of each Fund to obtain the best price and execution for its
transactions. Where best price and execution may be obtained from more than one
dealer, the Adviser may, in its discretion, purchase and sell securities through
dealers who provide research, statistical and other information to the Adviser.
Such services may be used by the Adviser for all of its investment advisory
accounts and, accordingly, not all such services may be used by the Adviser in
connection with a Fund. The supplemental information received from a dealer is
in addition to the services required to be performed by the Adviser under the
Advisory Agreement, and the expenses of the Adviser will not necessarily be
reduced as a result of the receipt of such information. Consistent with the
Rules of Fair Practice of the National Association of Securities Dealers, Inc.,
and subject to seeking best price and execution, a Fund may consider sales of
shares of a Fund as a factor in the selection of dealers to enter into portfolio
transactions with a Fund.

     The Funds may deal in some instances in securities that are not listed on a
national stock exchange but are traded in the over-the-counter market. The Funds
may also purchase listed securities through the third market, i.e., from a
dealer that is not a member of the exchange on which a security is listed. Where
transactions are executed in the over-the-counter market or third market, the
Funds will seek to deal with the primary market makers, but when necessary in
order to obtain the best price and execution, it will utilize the services of
others. In all cases, the Funds will attempt to negotiate best execution.

Brokerage Allocation and Other Practices

     Neither a Fund nor the Adviser has entered into agreements or
understandings with any brokers or dealers regarding the placement of securities
transactions because of research or statistical services they provide. To the
extent that such persons or firms supply investment information to the Adviser
for use in rendering investment advice to a Fund, such information may be
supplied at no cost to the Adviser and, therefore, may have the effect of
reducing the expenses of the Adviser in rendering advice to a Fund. While it is
impossible to place an actual dollar value on such investment information, its
receipt by the Adviser probably does not reduce the overall expenses of the
Adviser to any material extent.

     The investment information provided to the Adviser is of the types
described in Section 28(e)(3) of the Securities Exchange Act of 1934 and is
designed to augment the Adviser's own internal research and investment strategy
capabilities. Research and statistical services furnished by brokers through
whom a Fund effects securities transactions are used by the Adviser in carrying
out its investment management responsibilities with respect to all its client
accounts but not all such services may be utilized by the Adviser in connection
with a Fund. A Fund will deal in some instances in equity securities, which are
not listed on a national stock exchange but are traded in the over-the-counter
market. Where transactions are executed in the over-the-counter market, a Fund
will seek to deal with the primary market makers, but when necessary in order to
obtain the best price and execution, it will utilize the services of others. In
all cases, a Fund will attempt to negotiate best execution.

     A Fund may from time to time place orders for the purchase or sale of
securities (including listed call options) with SCB & Co., an affiliate of the
Adviser. With respect to orders placed with SCB & Co. for execution on a
national securities exchange, commissions received must conform to Section
17(e)(2)(A) of the 1940 Act and Rule 17e-1 thereunder, which permit an
affiliated person of a registered investment company (such as a Fund), or any
affiliated person of such person, to receive a brokerage commission from such
registered investment company provided that such commission is reasonable and
fair compared to the commissions received by other brokers in connection with
comparable transactions involving similar securities during a comparable period
of time.

                                  DISTRIBUTIONS

     Each Fund intends to distribute monthly its net investment income. Net
capital gains, if any, will normally be distributed at least annually to holders
of common stock to the extent such net capital gains are not necessary to
satisfy the dividend, redemption, or liquidation preferences of any preferred
stock. For tax purposes, the Funds are currently required to allocate net
capital gains and other taxable income, if any, between shares of common stock
and shares of preferred stock in proportion to total distributions paid to each
class for the year in which such net capital gains or other taxable income is
realized. See "Taxation - United States Federal Income Taxes - Distributions."
While any shares of preferred stock are outstanding, the Funds may not declare
any cash dividend or other distribution on their common stock, unless at the
time of such declaration, (a) all accrued preferred stock dividends have been
paid and (b) the NAV of the Funds' portfolios (determined after deducting the
amount of such dividend or other distribution) is at least 200% of the
liquidation value of the outstanding preferred stock (expected to equal the
original purchase price per share plus any accrued and unpaid dividends
thereon). This limitation on the Funds' ability to make distributions on their
common stock could under certain circumstances impair the ability of the Funds
to maintain their qualifications for taxation as regulated investment companies.
See "Taxation - United States Federal Income Taxes - Distributions."

                                    TAXATION

     Taxation of the Funds. The Funds intend to qualify each year as regulated
investment companies under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). In order to qualify for the special tax treatment accorded
regulated investment companies and their stockholders, the Funds must, among
other things:

     (a) derive at least 90% of their gross income from dividends, interest,
     payments with respect to certain securities loans, gains from the sale of
     stock, securities or foreign currencies, other income (including but not
     limited to gains from options, futures, or forward contracts) derived with
     respect to their business of investing in such stock, securities, or
     currencies or net income from certain publicly traded partnerships;

     (b) distribute with respect to each taxable year at least 90% of the sum of
     their taxable net investment income (which includes the excess, if any, of
     net short-term capital gains over net long-term capital losses) and their
     net tax-exempt income for such year; and

     (c) diversify their holdings so that, at the end of each quarter of a
     Fund's taxable year, (i) at least 50% of the market value of a Fund's
     assets is represented by cash and cash items, U.S. Government securities,
     securities of other regulated investment companies, and other securities
     limited in respect of any one issuer to a value not greater than 5% of the
     value of a Fund's total assets and not more than 10% of the outstanding
     voting securities of such issuer, (ii) not more than 25% of the value of a
     Fund's assets is invested in the securities (other than those of the U.S.
     Government or other regulated investment companies) of any one issuer or of
     two or more issuers that a Fund controls and which are engaged in the same,
     similar, or related trades or businesses and (iii) not more than 25% of the
     value of a Fund's assets is invested in securities of one or more
     "qualified publicly traded partnerships".

     If a Fund qualifies as a regulated investment company that is accorded
special tax treatment, that Fund will not be subject to federal income tax on
income distributed in a timely manner to its stockholders in the form of
dividends (including capital gain dividends).

     If a Fund failed to qualify as a regulated investment company accorded
special tax treatment in any taxable year, that Fund would be subject to tax on
its taxable income at corporate rates, and all distributions from earnings and
profits, including any distributions of net tax-exempt income and net long-term
capital gains, would be taxable to stockholders as ordinary income or "qualified
dividend income" taxable at a maximum rate of 15% to U.S. non-corporate
stockholders (through 2010) provided certain requirements are satisfied. Such
distributions generally would be eligible for the dividends received deduction
in the case of corporate stockholders. In addition, a Fund could be required to
recognize unrealized gains, pay substantial taxes and interest and make
substantial distributions before requalifying as a regulated investment company
that is accorded special tax treatment.

     Each Fund may retain for investment its net capital gain. However, if a
Fund retains any net capital gain or any net investment income, it will be
subject to tax at regular corporate rates on the amount retained. Each Fund
intends to distribute at least annually to its stockholders all or substantially
all of its net tax-exempt interest and any net investment income and net capital
gain.

     If a Fund fails to distribute in a calendar year at least an amount equal
to the sum of 98% of its ordinary income for such year and 98% of its capital
gain net income for the one-year period ending October 31 of such calendar year,
plus any undistributed ordinary income and capital gain net income from previous
years, that Fund will be subject to a 4% excise tax on the undistributed
amounts. For this purpose, any income or gain retained by a Fund that is subject
to corporate tax will be considered to have been distributed by year end. A
dividend paid to stockholders in January of a year generally is deemed to have
been paid by a Fund on December 31 of the preceding year, if the dividend was
declared and payable to stockholders of record on a date in October, November or
December of that preceding year. Each Fund intends generally to make
distributions sufficient to avoid imposition of the 4% excise tax.

     If at any time when preferred stock is outstanding a Fund does not meet
applicable asset coverage requirements, it will be required to suspend
distributions to common stockholders until the requisite asset coverage is
restored. Any such suspension may cause a Fund to pay the 4% federal excise tax
and may, in certain circumstances, prevent a Fund from qualifying for treatment
as a regulated investment company. Each Fund may redeem preferred stock in an
effort to comply with the distribution requirement applicable to regulated
investment companies and to avoid income and excise taxes. There can be no
assurance, however, that any such action would achieve such objectives.

     Fund Distributions. Distributions from the Funds (other than
exempt-interest dividends, as discussed below) will be taxable to stockholders
as ordinary income to the extent derived from net investment income (which
includes any net short-term capital gains). Distributions of net capital gain
(that is, the excess of net gains from the sale of capital assets held more than
one year over net losses from the sale of capital assets held for not more than
one year) will be taxable to stockholders as long-term capital gain, regardless
of how long a stockholder has held the shares in a Fund. The Funds'
distributions will not qualify for the dividends received deduction for
corporate stockholders. It is not expected that any portion of the Funds'
distributors will be treated as "qualified dividend income" taxable at a maximum
rate of 15% to U.S. non-corporate stockholders (through 2010).

     Alternative Minimum Tax. Current federal income tax law imposes an AMT with
respect to both corporations and individuals. Interest on tax-exempt Municipal
Securities issued after August 7, 1986 that are "specified private activity
bonds," and the proportionate share of any exempt-interest dividend paid by a
regulated investment company, such as the Funds, which receive interest from
such specified private activity bonds, will be treated as an item of tax
preference for purposes of the AMT, though for regular Federal income tax
purposes such interest will remain fully tax-exempt. The Funds will annually
notify stockholders of the portion of exempt-interest dividends paid by the
Funds that will be treated as an item of tax preference for purposes of the AMT.
In addition, interest on all tax-exempt Municipal Securities, and therefore all
distributions by the Funds that would otherwise be tax-exempt, will be included
in the "adjusted current earnings" of corporations for AMT purposes.

     The interest on AMT Municipal Securities, in which the Funds will invest a
substantial portion of their assets, is not tax-exempt for federal income tax
purposes when received by persons who are "substantial users" of the facilities
financed by such bonds or by "related persons" of such substantial users.
Consequently, the Funds may not be appropriate investments for persons who are
considered either a substantial user or a related person under the applicable
rules, and prospective investors should consult their tax advisers on whether
they would constitute substantial users or related persons of facilities
financed by AMT Municipal Securities before purchasing shares of the Funds.

     Exempt-interest dividends. The Funds will be qualified to pay
exempt-interest dividends to their stockholders only if, at the close of each
quarter of each Fund's taxable year, at least 50% of the total value of that
Fund's assets consists of obligations the interest on which is exempt from
federal income tax under Code Section 103(a). Distributions from each Fund will
constitute exempt-interest dividends to the extent of that Fund's tax-exempt
interest income (net of expenses and amortized bond premium). Distributions that
the Funds properly designate as exempt-interest dividends are treated as
interest excludable from stockholders' gross income for federal income tax
purposes, although such distributions are required to be reported on the
stockholders' federal income tax returns and may be taxable for state and local
purposes. Because the Funds intend to qualify to pay exempt-interest dividends,
the Funds may be limited in their ability to enter into taxable transactions
involving forward commitments, repurchase agreements, financial futures and
options contracts on financial futures, tax-exempt bond indices and other
assets.

     The Funds designate distributions made to the share classes as consisting
of a portion of each type of income distributed by the Funds. The portion of
each type of income deemed received by each class of stockholders is equal to
the portion of total Fund dividends received by such class for that taxable
year. Thus, the Funds will designate dividends paid as exempt-interest dividends
in a manner that allocates such dividends between the Preferred and common
stockholders in proportion to the total dividends paid to each class during or
with respect to the taxable year, or otherwise as required by applicable law.
Long-term capital gain distributions and other income subject to regular federal
income tax will similarly be allocated between the two (or more) classes.

     Dividend and capital gains distributions will be taxable as described above
whether received in cash or in shares. A stockholder whose distributions are
reinvested in shares will be treated as having received a dividend equal to the
fair market value of the new shares issued to the stockholder, or the amount of
cash allocated to the stockholder for the purchase of shares on its behalf.

     Part or all of the interest on indebtedness, if any, incurred or continued
by a stockholder to purchase or carry shares of the Funds paying exempt-interest
dividends is not deductible. Under rules used by the Internal Revenue Service
(the "Service") to determine when borrowed funds are considered used for the
purpose of purchasing or carrying particular assets, the purchase of shares may
be considered to have been made with borrowed funds even though such funds are
not directly traceable to the purchase of shares.

     The Funds may invest in tax-exempt municipal securities subject to the AMT.
Under current federal income tax law, (i) interest on tax-exempt municipal
securities issued after August 7, 1986 which are "specified private activity
bonds" and the proportionate share of any exempt-interest dividend paid by a
regulated investment company which receives interest from such specified private
activity bonds will be treated as an item of tax preference for purposes of the
AMT imposed on individuals and corporations although for regular federal income
tax purposes such interest will remain fully tax-exempt, and (ii) interest on
all tax-exempt obligations and all exempt-interest dividends will be included in
"adjusted current earnings" of corporations for AMT purposes.

     In general, exempt-interest dividends, if any, attributable to interest
received on certain private activity obligations and certain industrial
development bonds will not be tax-exempt to any stockholders who are
"substantial users," within the meaning of Section 147(a) of the Code, of the
facilities financed by such obligations or bonds or who are "related persons" of
such substantial users.

     Each Fund will inform investors within 60 days of that Fund's taxable
year-end of the percentage of its income distributions designated as tax-exempt.
The percentage is applied uniformly to all distributions made during the year.
The percentage of income designated as tax-exempt for any particular
distribution may be substantially different from the percentage of each Fund's
income that was tax-exempt during the period covered by the distribution.

     The Funds will allocate distributions to stockholders that are treated as
tax-exempt interest and as long-term capital gain and ordinary income, if any,
among the common stock and preferred stock in proportion to total dividends paid
to each class for the year.

     Hedging Transactions. If the Funds engage in hedging transactions,
including hedging transactions in options, futures contracts, and straddles, or
other similar transactions, it will be subject to special tax rules (including
constructive sale, mark-to-market, straddle, wash sale, and short sale rules),
the effect of which may be to accelerate income to the Funds, defer losses to
the Funds, cause adjustments in the holding periods of the Funds' securities,
affect whether gains and losses realized by the Funds are ordinary or capital,
convert long-term capital gains into short-term capital gains or convert
short-term capital losses into long-term capital losses. These rules could
therefore affect the amount, timing and character of distributions to
stockholders. Income earned as a result of the Funds' hedging activities will
not be eligible to be treated as exempt-interest dividends when distributed to
stockholders. The Funds will endeavor to make any available elections and
entries in its books and records pertaining to such transactions in a manner
believed to be in the best interests of the Funds and their stockholders.

     Return of Capital Distributions. If a Fund makes a distribution to you in
excess of its current and accumulated earnings and profits in any taxable year,
the excess distribution will be treated as a return of capital to the extent of
your tax basis in your shares, and thereafter as capital gain. A return of
capital is not taxable, but it reduces your tax basis in your shares, thus
reducing any loss or increasing any gain on a subsequent taxable disposition by
you of your shares.

     Dividends and distributions on the Funds' shares are generally subject to
federal income tax as described herein, even though such dividends and
distributions may economically represent a return of a particular stockholder's
investment. Such distributions are likely to occur in respect of shares
purchased at a time when the Funds' NAV reflects gains that are either
unrealized, or realized but not distributed. Such realized gains may be required
to be distributed even when the Funds' NAV also reflects unrealized losses.
Distributions are taxable to a stockholder even if they are paid from income or
gains earned by the Fund prior to the stockholder's investment (and thus
included in the price paid by the stockholder).

     Securities Issued or Purchased at a Discount. The Funds' investment in
securities issued at a more than de minimis discount, and certain other
obligations, will (and investments in securities purchased at a discount may)
require the Funds to accrue and distribute income not yet received. In order to
generate sufficient cash to make the requisite distributions, the Funds may be
required to sell securities in its portfolio that it otherwise would have
continued to hold.

     Sale or Redemption of Shares. The sale, exchange or redemption of Fund
shares will give rise to gain or loss in an amount equal to the difference
between the proceeds of the sale, exchange or redemption and the stockholder's
adjusted tax basis in the shares. Any gain or loss realized upon a taxable
disposition of shares held as a capital asset will be treated as long-term
capital gain or loss if the shares have been held for more than 12 months.
Otherwise, the gain or loss on the taxable disposition of Fund shares held as a
capital asset will be treated as short-term capital gain or loss. However, if a
stockholder sells shares at a loss within six months of purchase, any loss will
be disallowed for federal income tax purposes to the extent of any
exempt-interest dividends received on such shares. In addition, any loss
realized upon a taxable disposition of shares held for six months or less but
not disallowed as provided in the preceding sentence will be treated as
long-term, rather than short-term, to the extent of any long-term capital gain
distributions received by the stockholder with respect to the shares. All or a
portion of any loss realized upon a taxable disposition of Fund shares will be
disallowed if other substantially identical shares of a Fund are purchased
within 30 days before or after the disposition. In such a case, the basis of the
newly purchased shares will be adjusted to reflect the disallowed loss.

     If a Fund redeems some but not all of the preferred stock held by a
preferred stockholder and such stockholder is treated as having received a
taxable dividend upon such redemption, there is a remote risk that non-redeeming
preferred stockholders will be treated as having received taxable distributions
from that Fund.

     Backup Withholding. The Funds generally are required to withhold and remit
to the U.S. Treasury a percentage of the taxable dividends and other
distributions paid to any non- corporate stockholder who fails to properly
furnish a Fund with a correct taxpayer identification number (TIN), who has
under-reported dividend or interest income, or who fails to certify to the Funds
that he or she is not subject to such withholding. Backup withholding is not an
additional tax; rather any amounts withheld may be credited against the
stockholder's U.S. federal income tax liability.

     General. The federal income tax discussion set forth above is for general
information only. Prospective investors should consult their tax advisers
regarding the specific federal tax consequences of purchasing, holding, and
disposing of shares of the Funds, as well as the effects of state, local and
foreign tax law and any proposed tax law changes.

UNITED STATES FEDERAL INCOME TAXATION OF A FUND

     The following discussion relates to certain significant United States
federal income tax consequences to a Fund with respect to the determination of
its "investment company taxable income" each year. This discussion assumes that
a Fund will be taxed as a regulated investment company for each of its taxable
years.

     Currency Fluctuations - "Section 988" Gains or Losses. Under the Code,
gains or losses attributable to fluctuations in exchange rates which occur
between the time a Fund accrues interest or other receivables or accrues
expenses or other liabilities denominated in a foreign currency and the time a
Fund actually collects such receivables or pays such liabilities are treated as
ordinary income or ordinary loss. Similarly, gains or losses from the
disposition of foreign currencies, from the disposition of debt securities
denominated in a foreign currency, or from the disposition of a forward contract
denominated in a foreign currency which are attributable to fluctuations in the
value of the foreign currency between the date of acquisition of the asset and
the date of disposition also are treated as ordinary income or loss. These gains
or losses, referred to under the Code as "section 988" gains or losses, increase
or decrease the amount of a Fund's investment company taxable income available
to be distributed to its stockholders as ordinary income, rather than increasing
or decreasing the amount of a Fund's net capital gain. Because section 988
losses reduce the amount of ordinary dividends a Fund will be allowed to
distribute for a taxable year, such section 988 losses may result in all or a
portion of prior dividend distributions for such year being recharacterized as a
non-taxable return of capital to stockholders, rather than as an ordinary
dividend, reducing each stockholder's basis in his Fund shares. To the extent
that such distributions exceed such stockholder's basis, each will be treated as
a gain from the sale of shares.

     Options and Futures Contracts. Certain listed options and regulated futures
contracts are considered "section 1256 contracts" for federal income tax
purposes. Section 1256 contracts held by a Fund at the end of each taxable year
will be "marked to market" and treated for federal income tax purposes as though
sold for fair market value on the last business day of such taxable year. Gain
or loss realized by a Fund on section 1256 contracts will be considered 60%
long-term and 40% short-term capital gain or loss. A Fund can elect to exempt
its section 1256 contracts which are part of a "mixed straddle" (as described
below) from the application of section 1256.

     With respect to over-the-counter put and call options, gain or loss
realized by a Fund upon the lapse or sale of such options held by the Fund will
be either long-term or short-term capital gain or loss depending upon the Fund's
holding period with respect to such option. However, gain or loss realized upon
the lapse or closing out of such options that are written by a Fund will be
treated as short-term capital gain or loss. In general, if a Fund exercises an
option, or if an option that the Fund has written is exercised, gain or loss on
the option will not be separately recognized but the premium received or paid
will be included in the calculation of gain or loss upon disposition of the
property underlying the option.

     Tax Straddles. Any option, futures contract, forward contract, or other
position entered into or held by a Fund in conjunction with any other position
held by the Fund may constitute a "straddle" for federal income tax purposes. A
straddle of which at least one, but not all, the positions are section 1256
contracts may constitute a "mixed straddle." In general, straddles are subject
to certain rules that may affect the character and timing of a Fund's gains and
losses with respect to straddle positions by requiring, among other things, that
(i) loss realized on disposition of one position of a straddle not be recognized
to the extent that the Fund has unrealized gains with respect to the other
position in such straddle; (ii) the Fund's holding period in straddle positions
be suspended while the straddle exists (possibly resulting in gain being treated
as short-term capital gain rather than long-term capital gain); (iii) losses
recognized with respect to certain straddle positions which are part of a mixed
straddle and which are non-section 1256 positions be treated as 60% long-term
and 40% short-term capital loss; (iv) losses recognized with respect to certain
straddle positions which would otherwise constitute short-term capital losses be
treated as long-term capital losses; and (v) the deduction of interest and
carrying charges attributable to certain straddle positions may be deferred. The
Treasury Department is authorized to issue regulations providing for the proper
treatment of a mixed straddle where at least one position is capital. No such
regulations have yet been issued. Various elections are available to a Fund
which may mitigate the effects of the straddle rules, particularly with respect
to mixed straddles. In general, the straddle rules described above do not apply
to any straddles held by a Fund all of the offsetting positions of which consist
of section 1256 contracts.

     Zero Coupon Treasury Securities. Under current federal tax law, a Fund will
receive net investment income in the form of interest by virtue of holding
Treasury bills, notes and bonds, and will recognize interest attributable to it
under the original issue discount rules of the Code from holding zero coupon
Treasury securities. Current federal tax law requires that a holder (such as a
Fund) of a zero coupon security accrue a portion of the discount at which the
security was purchased as income each year even though a Fund receives no
interest payment in cash on the security during the year. Accordingly, a Fund
may be required to pay out as an income distribution each year an amount which
is greater than the total amount of cash interest the Fund actually received.
Such distributions will be made from the cash assets of a Fund or by liquidation
of portfolio securities, if necessary. A Fund may realize a gain or loss from
such sales. In the event a Fund realize net capital gains from such
transactions, its stockholders may receive a larger capital gain distribution,
if any, than they would have received in the absence of such transactions.

     Government Guaranteed Mortgage Pass-Through Securities. Mortgage
pass-through securities such as GNMA Certificates, FNMA Certificates, and FHLMC
Certificates generally are taxable as trusts for Federal income tax purposes,
with the certificate holders treated as the owners of the trust involved. As a
result, payments of interest, principal and prepayments made on the underlying
mortgage pool are taxed directly to certificate holders such as a Fund. Payments
of interest, principal and prepayments made on the underlying mortgage pool will
therefore generally maintain their character when received by a Fund.

NOTES TO FINANCIAL STATEMENTS
PRO FORMA ALLIANCE
NATIONAL MUNICIPAL INCOME FUND
                                      Alliance National Municipal Income Fund
April 30, 2006 (unaudited)              ACM Municipal Securities Income Fund
--------------------------------------------------------------------------------

NOTE A: General

The Pro Forma Alliance National Municipal Income Fund Financial Statements give
effect to the proposed acquisition (the "Acquisition") of the assets and
liabilities of ACM Municipal Securities Income Fund, Inc. (the "Acquired Fund")
by Alliance National Municipal Income Fund, Inc. (the "Fund" or "Acquiring
Fund") pursuant to Agreements and Plans of Reorganization. The Acquisition would
be accomplished by a tax-free exchange of the assets and liabilities of ACM
Municipal Securities Income Fund for shares of the Fund.

The Fund commenced operations on January 28, 2002. The Fund's unaudited Pro
Forma Portfolio of Investments, Statement of Assets and Liabilities and
Statement of Operations are prepared as though the Acquisition was effective for
the period May 1, 2005 - April 30, 2006. You should read them in conjunction
with the Fund's historical financial statements, which are included in the
Fund's Statement of Additional Information. The Fund's Pro Forma Statement of
Operations reflects the assumption that certain expense would be lower for the
combined Fund as a result of the Acquisition. The estimated Acquisition expenses
of approximately $372,000 shall be paid by the Funds, such that the Fund will
bear $138,000 and the Acquired Fund will bear $234,000 of the cost. Acquisition
expenses include the costs of proxy solicitation, except that the Acquired Fund
will bear its own costs associated with the disposition of any assets or
liabilities not being transferred to the Fund in connection with the
Acquisition.

NOTE B: Significant Accounting Policies

The Fund's Pro Forma financial statements have been prepared in conformity with
U.S. generally accepted accounting principles, which require management to make
certain estimates and assumptions that affect the reported amounts of assets and
liabilities in the financial statements and amounts of income and expenses
during the reporting period. Actual results could differ from those estimates.

1. Security Valuation

Portfolio securities are valued at their current market value determined on the
basis of market quotations or, if market quotations are not readily available or
are deemed unreliable, at "fair value" as determined in accordance with
procedures established by and under the general supervision of the Fund's Board
of Directors.

In general, the market value of securities which are readily available and
deemed reliable are determined as follows: Securities listed on a national
securities exchange or on a foreign securities exchange are valued at the last
sale price at the close of the exchange or foreign securities exchange. If there
has been no sale on such day, the securities are valued at the mean of the
closing bid and asked prices on such day. Securities listed on more than one
exchange are valued by reference to the principal exchange on which the
securities are traded; securities not listed on an exchange but traded on The
NASDAQ Stock Market, Inc. ("NASDAQ") are valued in accordance with the NASDAQ
Official Closing Price; listed put or call options are valued at the last sale
price. If there has been no sale on that day, such securities will be valued at
the closing bid prices on that day; open futures contracts and options thereon
are valued using the closing settlement price or, in the absence of such a
price, the most recent quoted bid price. If there are no quotations available
for the day of valuation, the last available closing settlement price is used;
securities traded in the over-the-counter market, ("OTC") (but excluding
securities traded on NASDAQ) are valued at the mean of the current bid and asked
prices as reported by the National Quotation Bureau or other comparable sources;
U.S. Government securities and other debt instruments having 60 days or less
remaining until maturity are valued at amortized cost if their original maturity
was 60 days or less; or by amortizing their fair value as of the 61st day prior
to maturity if their original term to maturity exceeded 60 days; fixed-income
securities, including mortgage backed and asset backed securities, may be valued
on the basis of prices provided by a pricing service or at a price obtained from
one or more of the major broker/dealers. In cases where broker/dealer quotes are
obtained, AllianceBernstein L.P., may establish procedures whereby changes in
market yields or spreads are used to adjust, on a daily basis, a recently
obtained quoted price on a security; and OTC and other derivatives are valued on
the basis of a quoted bid price or spread from a major broker/dealer in such
security.

     Securities for which market quotations are not readily available (including
restricted securities) or are deemed unreliable are valued at fair value.
Factors considered in making this determination may include, but are not limited
to, information obtained by contacting the issuer, analysts, analysis of the
issuer's financial statements or other available documents.

2. Taxes

It is the Fund's policy to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its
investment company taxable income and net realized gains, if any, to
shareholders. Therefore, no provisions for federal income or excise taxes are
required.

3. Investment Income and Investment Transactions

Interest income is accrued daily. Investment transactions are accounted for on
the trade date securities are purchased or sold. Investment gains and losses are
determined on the identified cost basis. The Fund amortizes premiums and
accretes original issue discount and market discount as adjustments to interest
income.

4. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the
ex-dividend date. Income dividends and capital gains distributions are
determined in accordance with federal tax regulations and may differ from those
determined in accordance with U.S. generally accepted accounting principles. To
the extent these differences are permanent, such amounts are reclassified within
the capital accounts based on their federal tax basis treatment; temporary
differences do not require such reclassification.

NOTE C: Advisory Fee and other Transactions with Affiliates

Under the terms of the investment advisory agreement, the Fund pays the Adviser
an advisory fee at an annual rate of .65% of 1% of the Fund's average daily net
assets applicable to common and preferred shareholders. Such fee is accrued
daily and paid monthly. The Adviser has voluntarily agreed to waive a portion of
its fees or reimburse the Fund for expenses in the amount of 0.25% of the Fund's
average daily net assets applicable to common and preferred shareholders for the
first 5 full years of the Fund's operations, 0.20% of the Fund's average daily
net assets applicable to common and preferred shareholders in year 6, 0.15% in
year 7, 0.10% in year 8 and 0.05% in year 9. For the twelve months ended April
30, 2006, such reimbursement waivers amounted to $1,815,203.

Under the terms of a Shareholder Inquiry Agency Agreement with AllianceBernstein
Investor Services, Inc. (prior to February 24, 2006 known as Alliance Global
Investor Services, Inc.) ("ABIS"), an affiliate of the Adviser, the Fund
reimburses ABIS for costs relating to servicing phone inquiries for the Fund.
During the twelve months ended April 30, 2006, there was no reimbursement paid
to ABIS.

NOTE D: Capital Shares

The pro-forma combining net assets value per share assumes the issuance of
Acquiring Fund shares to Acquired Fund shareholders in connection with the
proposed merger. The number of shares assumed to be issued is equal to the net
asset value per share of the Acquired Fund divided by the net asset value per
share of the Acquiring Fund as of April 30, 2006. The pro-forma number of shares
outstanding for the combined entity consists of the following at April 30, 2006:

                             Additional Shares         Total Shares
   Shares of Acquiring        Assumed Issued           Outstanding
  Fund Pre-Combination          with Merger          Post-Combination

--------------------------------------------------------------------------------
                      U.S. MUNICIPAL AND TAX-EXEMPT RATINGS
--------------------------------------------------------------------------------

Moody's Investors Service, Inc.
-------------------------------

Aaa                 Bonds which are rated Aaa are judged to be of the best
                    quality. They carry the smallest degree of investment risk
                    and are generally referred to as "gilt edge." Interest
                    payments are protected by a large or by an exceptionally
                    stable margin and principal is secure. While the various
                    protective elements are likely to change, such changes as
                    can be visualized are most unlikely to impair the
                    fundamentally strong position of such issues.

Aa                  Bonds which are rated Aa are judged to be of high quality by
                    all standards. Together with the Aaa group they comprise
                    what are generally known as high grade bonds. They are rated
                    lower than the best bonds because margins of protection may
                    not be as large as in Aaa securities or fluctuation of
                    protective elements may be of greater amplitude or there may
                    be other elements present which make the long-term risks
                    appear somewhat larger than the Aaa securities.

A                   Bonds which are rated A possess many favorable investment
                    attributes and are to be considered as upper-medium-grade
                    obligations. Factors giving security to principal and
                    interest are considered adequate but elements may be present
                    which suggest a susceptibility to impairment some time in
                    the future.

Baa                 Bonds which are rated Baa are considered as medium-grade
                    obligations, i.e., they are neither highly protected nor
                    poorly secured. Interest payments and principal security
                    appear adequate for the present but certain protective
                    elements may be lacking or may be characteristically
                    unreliable over any great length of time. Such bonds lack
                    outstanding investment characteristics and in fact have
                    speculative characteristics as well.

Ba                  Bonds which are rated Ba are judged to have speculative
                    elements; their future cannot be considered as well-assured.
                    Often the protection of interest and principal payments may
                    be very moderate and thereby not well safeguarded during
                    both good and bad times over the future. Uncertainty of
                    position characterizes bonds in this class.

B                   Bonds which are rated B generally lack characteristics of
                    the desirable investment. Assurance of interest and
                    principal payments or of maintenance of other terms of the
                    contract over any long period of time may be small.

Caa                 Bonds which are rated Caa are of poor standing. Such issues
                    may be in default or there may be present elements of danger
                    with respect to principal or interest.

Ca                  Bonds which are rated Ca represent obligations which are
                    speculative in a high degree. Such issues are often in
                    default or have other marked shortcomings.

C                   Bonds which are rated C are the lowest rated class of bonds
                    and issues so rated can be regarded as having extremely poor
                    prospects of ever attaining any real investment standing.

Absence of Rating   When no rating has been assigned or where a rating has been
                    suspended or withdrawn, it may be for reasons unrelated to
                    the quality of the issue.

Should no rating be assigned, the reason may be one of the following:

1.   An application for rating was not received or accepted.

2.   The issue or issuer belongs to a group of securities or companies that are
     unrated as a matter of policy.

3.   There is a lack of essential data pertaining to the issue or issuer.

4.   The issue was privately placed, in which case the rating is not published
     in Moody's publications.

Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.

Note      Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
          classification from Aa through Caa in its corporate bond rating
          system. The modifier 1 indicates that the security ranks in the higher
          end of its generic rating category; the modifier 2 indicates a
          mid-range ranking; and the modifier 3 indicates that the issue ranks
          in the lower end of its generic rating category.

Standards & Poor's Ratings Services
-----------------------------------

AAA                      Debt rated AAA has the highest rating assigned by S&P.
                         Capacity to pay interest and repay principal is
                         extremely strong.

AA                       Debt rated AA has a very strong capacity to pay
                         interest and repay principal and differs from the
                         highest rated issues only in small degree.

A                        Debt rated A has a strong capacity to pay interest and
                         repay principal although it is somewhat more
                         susceptible to the adverse effects of changes in
                         circumstances and economic conditions than debt in
                         higher rated categories.

BBB                      Debt rated BBB normally exhibits adequate protection
                         parameters. However, adverse economic conditions or
                         changing circumstances are more likely to lead to a
                         weakened capacity to pay interest and repay principal
                         for debt in this category than in higher rated
                         categories.

BB, B, CCC, CC, C        Debt rated BB, B, CCC, CC or C is regarded as having
                         significant speculative characteristics. BB indicates
                         the lowest degree of speculation and C the highest.
                         While such debt will likely have some quality and
                         protective characteristics, these are outweighed by
                         large uncertainties or major exposures to adverse
                         conditions.

BB                       Debt rated BB is less vulnerable to nonpayment than
                         other speculative debt. However, it faces major ongoing
                         uncertainties or exposure to adverse business,
                         financial or economic conditions which could lead to an
                         inadequate capacity to pay interest and repay
                         principal.

B                        Debt rated B is more vulnerable to nonpayment than debt
                         rated BB, but there is capacity to pay interest and
                         repay principal. Adverse business, financial or
                         economic conditions will likely impair the capacity or
                         willingness to pay principal or repay interest.

CCC                      Debt rated CCC is currently vulnerable to nonpayment,
                         and is dependent upon favorable business, financial and
                         economic conditions to pay interest and repay
                         principal. In the event of adverse business, financial
                         or economic conditions, there is not likely to be
                         capacity to pay interest or repay principal.

CC                       Debt rated CC is currently highly vulnerable to
                         nonpayment.

C                        The C rating may be used to cover a situation where a
                         bankruptcy petition has been filed or similar action
                         has been taken, but payments are being continued.

D                        The D rating, unlike other ratings, is not prospective;
                         rather, it is used only where a default has actually
                         occurred.

Plus (+) or Minus (-)    The ratings from AA to CCC may be modified by the
                         addition of a plus or minus sign to show relative
                         standing within the major rating categories.

NR                       Not rated.

Fitch Ratings
-------------

AAA                      Bonds considered to be investment grade and of the
                         highest credit quality. The obligor has an
                         exceptionally strong ability to pay interest and repay
                         principal, which is unlikely to be affected by
                         reasonably foreseeable events.

AA                       Bonds considered to be investment grade and of very
                         high credit quality. The obligor's ability to pay
                         interest and repay principal is very strong, although
                         not quite as strong as bonds rated AAA. Because bonds
                         rated in the AAA and AA categories are not
                         significantly vulnerable to foreseeable future
                         developments, short-term debt of these issuers is
                         generally rated F- 1+.

A                        Bonds considered to be investment grade and of high
                         credit quality. The obligor's ability to pay interest
                         and repay principal is considered to be strong, but may
                         be more vulnerable to adverse changes in economic
                         conditions and circumstances than bonds with higher
                         ratings.

BBB                      Bonds considered to be investment grade and of
                         satisfactory credit quality. The obligor's ability to
                         pay interest and repay principal is considered to be
                         adequate. Adverse changes in economic conditions and
                         circumstances, however, are more likely to have adverse
                         impact on these bonds, and therefore impair timely
                         payment. The likelihood that the ratings of these bonds
                         will fall below investment grade is higher than for
                         bonds with higher ratings.

BB                       Bonds are considered speculative. The obligor's ability
                         to pay interest and repay principal may be affected
                         over time by adverse economic changes. However,
                         business and financial alternatives can be identified
                         which could assist the obligor in satisfying its debt
                         service requirements.

B                        Bonds are considered highly speculative. While bonds in
                         this class are currently meeting debt service
                         requirements, the probability of continued timely
                         payment of principal and interest reflects the
                         obligor's limited margin of safety and the need for
                         reasonable business and economic activity throughout
                         the life of the issue.

CCC                      Bonds have certain identifiable characteristics which,
                         if not remedied, may lead to default. The ability to
                         meet obligations requires an advantageous business and
                         economic environment.

CC                       Bonds are minimally protected. Default in payment of
                         interest and/or principal seems probable over time.

C                        Bonds are in imminent default in payment of interest or
                         principal.

DDD, DD, D               Bonds are in default on interest and/or principal
                         payments. Such bonds are extremely speculative and
                         should be valued on the basis of their ultimate
                         recovery value in liquidation or reorganization of the
                         obligor. DDD represents the highest potential for
                         recovery on these bonds, and D represents the lowest
                         potential for recovery.

Plus (+) Minus (-)       Plus and minus signs are used with a rating symbol to
                         indicate the relative position of a credit within the
                         rating category. Plus and minus signs, however, are not
                         used in the AAA, DDD, DD or D categories.

NR                       Indicates that Fitch does not rate the specific issue.
