APEX MUNICIPAL FUND, INC.

Managed Dividend Policy

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more consistent yield to the current trading price of shares
of Common Stock of the Fund, the Fund may at times pay out less than the entire
amount of net investment income earned in any particular month and may at times
in any particular month pay out such accumulated but undistributed income in
addition to net investment income earned in that month. As a result, the
dividends paid by the Fund for any particular month may be more or less than the
amount of net investment income earned by the Fund during such month. The Fund's
current accumulated but undistributed net investment income, if any, is
disclosed in the Statement of Assets, Liabilities and Capital, which comprises
part of the financial information included in this report.

DEAR SHAREHOLDER

For the year ended June 30, 2001, Apex Municipal Fund, Inc. earned $0.596 per
share income dividends, which included earned and unpaid dividends of $0.049.
This represents a net annualized yield of 6.30%, based on a month-end net asset
value of $9.45 per share. Over the same period, the Fund's total investment
return was +8.48%, based on a change in per share net asset value from $9.33 to
$9.45, and assuming reinvestment of $0.597 per share income dividends. For the
six-month period ended June 30, 2001, the Fund's total investment return was
+5.54%, based on a change in per share net asset value from $9.26 to $9.45, and
assuming reinvestment of $0.301 per share income dividends.

The Municipal Market Environment

During the six-month period ended June 30, 2001, among considerable weekly
volatility, long-term fixed-income bond yields generally moved higher. So far in
2001, investors generally focused on the actions taken by the Federal Reserve
Board to reverse the ongoing US economic slowdown. US economic growth fell into
the 1%-2% range in 2001 after expanding at more than 5% during the first half of
2000. In mid-December 2000, the Federal Reserve Board announced that economic
conditions warranted the cessation of the series of short-term interest rate
increases initiated in February 2000. Citing declining consumer confidence and
weakening industrial production, the Federal Reserve Board at each of their
meetings in January, February and March of this year lowered short-term interest
rates in an effort to promote stronger US economic growth. Given continued weak
equity markets, investors focused on the declining supply of US Treasury
securities and forecasts of sizeable Federal budget surpluses. This positive
economic environment fostered a significant decline in US Treasury bond yields.
By late March 2001, US Treasury bond yields declined approximately 20 basis
points (0.20%) to 5.25%.

Despite additional actions by the Federal Reserve Board in April, May and June,
fixed-income securities were unable to maintain their earlier market gains.
Recovering US stock markets, especially the NASDAQ, caused many investors to
reallocate assets out of US Treasury securities to equities. Additionally, many
investors believed that the 275 basis point decline in short-term interest rates
engineered by the Federal Reserve Board over the last six months would
eventually rekindle a strong US economy with concomitant inflationary pressures.
In recent months, recovering equity markets, renewed inflationary fears, and the
expectation that the US economy will resume strong growth in late 2001 put
consistent pressures on fixed-income issues. By the end of June 2001, long-term
US Treasury bond yields rose to 5.75%, an increase of approximately 30 basis
points over the last six months.

During the last six months, tax-exempt bond yields also reacted to the Federal
Reserve Board actions and equity market volatility. However, this reaction was
muted in both intensity and degree. In early 2001, municipal bond yields traded
in a narrow range supported by a strong US Treasury market and continued
investor demand. As it became apparent that any proposed changes in the Federal
tax system were unlikely to have any immediate, material impact on existing
Federal tax brackets, tax-exempt bond yields responded by moving higher in early
2001. By late March 2001, long-term uninsured revenue bond yields, as measured
by the Bond Buyer Revenue Bond Index, approached 5.40%, a decline of
approximately 10 basis points from the end of December 2000. Similar to the US
Treasury market, tax-exempt bond yields were pushed higher during the remainder
of the period by equity market improvement in April, as well as the possibility
that the Federal Reserve Board was close to the end of its current interest rate
easing cycle. At the end of June 2001, long-term municipal bond yields rose to
approximately 5.50%, although over the past six months, they rose approximately
five basis points.

The recent relative outperformance of the tax-exempt bond market was
particularly impressive given the dramatic increase in long-term municipal bond
issuance during the June 2001 quarter. Historically, low municipal bond yields
have continued to allow municipalities to refund outstanding, high-couponed
debt. Also, as yields rose in early April, tax-exempt issuers rushed to issue
new financing, fearing higher yields in the coming months. During the past six
months, almost $135 billion in long-term tax-exempt bonds was issued, an
increase of over 40% compared to the same period a year ago. During the
three-month period ended June 30, 2001, tax-exempt bond issuance was
particularly heavy, with more than $75 billion in long-term municipal bonds
underwritten, an increase of over 45% compared to the same three-month period a
year ago.

Historically, June has been a period of weak investor demand for tax-exempt
products as investors are often forced to liquidate bond positions to meet
Federal and state tax payments. In recent months, there was no appreciable
selling by retail accounts. It has been noted that, thus far in 2001, new net
cash inflows into municipal bond mutual funds have reached $4 billion compared
to new net cash outflows of more than $13 billion for the same period a year
ago. This suggests that the positive technical structure of the municipal market
has remained intact. Also, the months of June and July tend to be periods of
strong retail demand in response to the larger-coupon income payments and
proceeds from bond maturities these months generate. Additionally, short-term
tax-exempt interest rates are poised to move lower. Seasonal tax pressures have
kept short-term municipal rates artificially high, although not as high as in
recent years. As these pressures abate, short-term interest rates are likely to
decline below 3%. As short-term interest rates decline, investors have tended to
extend maturities to take advantage of the steep municipal yield curve. We
believe all of these factors should enhance the tax-exempt market's technical
position in the coming months.

Looking forward, the municipal market's direction appears uncertain. Should the
US economy materially weaken into late summer, the Federal Reserve Board may be
forced to ease monetary policy to a greater extent than investors currently
expect. The prospect of two or three additional interest rate easings may push
fixed-income bond yields, including municipal bond yields, lower. However,
should the cumulative 275 basis point reduction in short-term interest rates by
the Federal Reserve Board and the economic stimulus produced by recent Federal
tax reform combine to restore consumer confidence and economic activity,
tax-exempt bond yields may not decline further. Given the strong technical
position of the municipal bond market, we believe the tax-exempt market is
poised to continue to outperform its taxable counterpart in the coming months.

Portfolio Strategy

During the six-month period ended June 30, 2001, the high-yield tax-exempt
market saw a marked improvement in valuations for much of the high-yield sector,
in contrast to the prior six-month period, in which the high-yield tax-exempt
market deteriorated significantly. The more constructive environment was
attributable to the abrupt and forceful easing of monetary policy in January
2001 by the Federal Reserve Board in response to a rapid deterioration in
economic fundamentals. Encouraged by prospects of steadily declining short-term
interest rates, fixed-income investors increased exposure to speculative-grade
credits in anticipation of the stimulative effect of an easing in monetary
policy. Implicit in the decision to reallocate asset weightings in this manner
has been the belief that credit spreads already reflect current weak economic
conditions. The anticipatory nature of markets suggests that investors are
looking beyond present circumstances and are now beginning to discount an
eventual economic rebound. In effect, the investors are demonstrating their
conviction that the Federal Reserve Board will be successful in its efforts to
reignite growth.

While these developments suggest a brighter outlook ahead, the months leading up
to the Federal Reserve Board's first rate reduction proved to be a difficult
environment for investors in the high-yield market. Poor liquidity and anemic
investor demand continued to chip away at valuations. The effect was all the
more pronounced as the late year bond market rally was largely confined to the
higher

investment-grade sectors. By year end, with investor sentiment at its nadir and
credit spreads near their widest point in several years, the stage was set for
the Federal Reserve Board's surprise move and the ensuing turnaround.

Our investment strategy remains largely unchanged. We have consistently sought
to manage reinvestment risk in an effort to stabilize the Fund's dividend stream
in a variety of interest rate environments. The distressed nature of the
high-yield market provided the opportunity to continue the gradual restructuring
of the Fund at some of the most attractive yields in recent years. Recent
additions to the Fund included a senior living project in North Carolina and tax
increment financing in Missouri. Despite the well-publicized financial woes
affecting California's two largest privately owned utilities, the utility sector
remains a favorite given current trends toward consolidation within the
industry. The Fund had no exposure to either utility and was unaffected by the
subsequent decline in market value of their respective debt obligations. Apart
from the debt issued by Southern California Edison and Pacific Gas and Electric,
the utility sector has been one of the best-performing groups in the tax-exempt
high-yield market. Notwithstanding our favorable outlook, this outperformance
prompted us to reduce our exposure modestly as a means of funding new purchases.

In Conclusion

We appreciate your ongoing interest in Apex Municipal Fund, Inc., and we look
forward to serving your investment needs in the months and years to come.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

Apex Municipal Fund, Inc. (the "Fund") is registered under the Investment
Company Act of 1940 as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require the use of management accruals and estimates. The Fund determines
and makes available for publication the net asset value of its Common Stock on a
weekly basis. The Fund's Common Stock is listed on the New York Stock Exchange
under the symbol APX. The following is a summary of significant accounting
policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various portfolio
investment strategies to increase or decrease the level of risk to which the
Fund is exposed more quickly and efficiently than transactions in other types of
instruments. Losses may arise due to changes in the value of the contract or if
the counterparty does not perform under the contract.

o Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Options--The Fund is authorized to write covered call options and purchase put
options. When the Fund writes an option, an amount equal to the premium received
by the Fund is reflected as an asset and an equivalent liability. The amount of
the liability is subsequently marked to market to reflect the current market
value of the option written.

When a security is purchased or sold through an exercise of an option, the
related premium paid (or received) is added to (or deducted from) the basis of
the security acquired or deducted from (or added to) the proceeds of the
security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes--It is the Fund's policy to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Interest income is recognized on the accrual basis. The
Fund will adopt the provisions to amortize all premiums and discounts on debt
securities effective July 1, 2001, as now required under the new AICPA Audit and
Accounting Guide for Investment Companies. The cumulative effect of this
accounting change will have no impact on the total net assets of the Fund, but
will result in a $34,920 increase to the cost of securities and a corresponding
$34,920 decrease to net unrealized depreciation, based on debt securities held
as of June 30, 2001.

(e) Dividends and distributions--Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .65% of the Fund's average weekly net assets.

Prior to January 1, 2001, FAM provided accounting services to the Fund at its
cost and the Fund reimbursed FAM for these services. FAM continues to provide
certain accounting services to the Fund. The Fund reimburses FAM at its cost for
such services. For the year ended June 30, 2001, the Fund reimbursed FAM an
aggregate of $24,777 for the above-described services. The Fund entered into an
agreement with State Street Bank and Trust Company ("State Street"), effective
January 1, 2001, pursuant to which State Street provides certain accounting
services to the Fund. The Fund pays a fee for these services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and/or ML & Co.

management. Our responsibility is to express an opinion on the financial
statements and the financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit

made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our

IMPORTANT TAX INFORMATION (unaudited)

All of the net investment income distributions declared monthly by Apex
Municipal Fund, Inc. during its taxable year ended June 30, 2001 qualify as
tax-exempt interest dividends for Federal income tax purposes.

Please retain this information for your records.

ABOUT INVERSE FLOATERS

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed rate, tax-exempt securities. To the extent the Fund invests in
inverse securities, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities.
