MuniEnhanced Fund, Inc.

The Benefits and Risks of Leveraging

MuniEnhanced Fund, Inc. utilizes leveraging to seek to enhance the yield and net
asset value of its Common Stock. However, these objectives cannot be achieved in
all interest rate environments. To leverage, the Fund issues Preferred Stock,
which pays dividends at prevailing short-term interest rates, and invests the
proceeds in long-term municipal bonds. The interest earned on these investments,
net of dividends to Preferred Stock, is paid to Common Stock shareholders in the
form of dividends, and the value of these portfolio holdings is reflected in the
per share net asset value of the Fund's Common Stock. However, in order to
benefit Common Stock shareholders, the yield curve must be positively sloped;
that is, short-term interest rates must be lower than long-term interest rates.
At the same time, a period of generally declining interest rates will benefit
Common Stock shareholders. If either of these conditions change, then the risks
of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value on the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange), may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

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 on 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 floaters, 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. As of January 31, 2004, the percentage of the Fund's
net assets invested in inverse floaters was 11.47%, before the deduction of
Preferred Stock.

Swap Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

A Letter From the President

Dear Shareholder

In my 35 years in the asset management business, 2003 was among the more
memorable. The year, which opened with geopolitical turmoil, unrelenting
economic uncertainty and a dismal continuation of a three-year equity market
slump, vigorously reversed course in the months that followed.

As we entered 2004, the equity markets maintained their positive momentum from
year-end 2003. For the six-month and 12-month periods ended January 31, 2004,
the Standard & Poor's (S&P) 500 Index returned +15.23% and +34.57%,
respectively. In the fixed income markets, investors willing to accept the
greatest risk were rewarded the most. This trend held true in the municipal bond
market as well, where high yield issues generally outperformed investment grade
bonds. For the six-month and 12-month periods ended January 31, 2004, the Lehman
Brothers Non-Investment Grade Index of municipal bonds posted respective returns
of +9.99% and +15.33%.

The major signposts indicate that we are seeing a shift from economic growth
fueled primarily by fiscal and monetary stimulus to a broader-based,
self-sustaining economic expansion. Gross domestic product growth, which peaked
at an annualized rate of 8.2% in the third quarter of 2003, is estimated at a
more sustainable 4% in the fourth quarter. That level of growth is expected to
repeat itself in the first quarter of 2004. For its part, the Federal Reserve
Board has reiterated its willingness to keep short-term interest rates at
current low levels to ensure the economy's strength.

Accompanying the increase in economic activity was an improvement in corporate
earnings. By the end of January, 298 of the S&P 500 companies had reported their
fourth-quarter results, and 67.4% of those exceeded expectations. In the
meantime, the American consumer, who continued to spend despite the faltering
economy, may get further incentive from another round of Federal tax refunds in
2004.

At Merrill Lynch Investment Managers, we believe the events and efforts of 2003
leave us with a much stronger economy and recent optimism suggests it is time
for investors to consider what can go right in 2004. We encourage you to revisit
your portfolio and your asset allocation strategy to ensure you are well
positioned to take advantage of the opportunities that lie ahead.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the months and years ahead.

                                        Sincerely,


                                        /s/ Terry K. Glenn

                                        Terry K. Glenn
                                        President and Director

A Discussion With Your Fund's Portfolio Manager

      In anticipation of rising interest rates ahead, we ended the year in a
slightly defensive stance so as to protect the Fund's net asset value and the
returns earned for shareholders over the past several months.

Discuss the recent market environment relative to municipal bonds.

The year was characterized by considerable month-to-month interest rate
volatility. By January 31, 2004, yields on long-term U.S. Treasury bonds were
moderately higher than they were a year earlier while long-term tax-exempt bond
yields were slightly lower than one year ago.

Throughout most of the first five months of the fiscal year, long-term bond
yields headed significantly lower while bond prices -- which move opposite of
yields -- rose in response to volatile equity markets, concerns about the war in
Iraq and continued sub-par economic growth. To spur business and consumer
activity, the Federal Reserve Board continued to lower short-term interest
rates. By mid-June, with the target Federal Funds rate at 1%, long-term U.S.
Treasury bond yields had fallen approximately 65 basis points (0.65%) to 4.17%.
The tide turned in July and August, as yields rose in reaction to improving
economic conditions and increasing confidence that the Federal Reserve Board was
through cutting short-term interest rates. By mid-August, U.S. Treasury bond
yields reached 5.45%, their highest level during the reporting period, before
generally moving lower for the remainder of the fiscal year. The decline was
largely influenced by sluggish employment growth and the Federal Reserve Board's
indication that it would remain on hold in the absence of material inflationary
pressures.

At January 31, 2004, long-term U.S. Treasury bond yields stood at 4.96%, 10
basis points higher than a year earlier. In contrast, long-term municipal
revenue bond yields had fallen approximately 20 basis points to 5.02%, as
measured by the Bond Buyer Revenue Bond Index. Yields on long-term tax-exempt
bonds rated Aaa -- the highest rating -- fell approximately 25 basis points to
end the period at 4.60%, according to Municipal Market Data.

The municipal bond market's performance benefited from solid investor demand for
tax-exempt products and a notable improvement in supply/demand dynamics as the
year wore on. In recent months, the pace of new municipal bond issuance has
greatly declined. For the 12 months ended January 31, 2004, municipalities
issued more than $375 billion in new securities, an increase of approximately 5%
compared to last year's issuance. Clearly, municipalities viewed the
historically low interest rates over the past year as an opportunity to finance
existing infrastructure needs and to refinance outstanding, higher-coupon debt.
Over the past six months, however, new issuance fell 11.5% compared to the same
period a year earlier. The decline was even more pronounced in the last three
months, with a decrease of more than 13% versus the same three months last year.
This decline in supply helped strengthen the municipal market's positive
technical position and enhanced recent performance. New-issue supply is expected
to remain manageable in early 2004 and should help support the tax-exempt bond
market's position as an attractive fixed income investment alternative.

How did the Fund perform during the year in light of the existing market
conditions?

For the 12-month period ended January 31, 2004, the Common Stock of MuniEnhanced
Fund, Inc. had net annualized yields of 6.09% and 6.43%, based on a year-end per
share net asset value of $11.83 and a per share market price of $11.22,
respectively, and $.721 per share income dividends. During the same period, the
total investment return on the Fund's Common Stock was +8.46%, based on a change
in per share net asset value from $11.65 to $11.83, and assuming reinvestment of
$.720 per share ordinary income dividends.

For the six-month period ended January 31, 2004, the total investment return on
the Fund's Common Stock was +9.49%, based on a change in per share net asset
value from $11.17 to $11.83, and assuming reinvestment of $.360 per share
ordinary income dividends.

For the six-month period ended January 31, 2004, the Fund's Auction Market
Preferred Stock ("AMPS") had an average yield as follows: Series A, .95%; Series
B, .94%; and Series C, .89%.

The Fund's total return performance, based on net asset value, for the year
modestly lagged that of its comparable Lipper category of Insured Municipal Debt
Funds (Leveraged), which had an average return of +8.68% for the 12-month period
ended January 31, 2004. (Funds in this Lipper category invest primarily in
municipal debt issues insured as to timely payment. These funds can be leveraged
via use of debt, preferred equity and/or reverse repurchase agree-

ments.) Much of the relative underperformance is attributed to poor results from
the Fund's single-family housing bonds during the first half of the period.
Single-family housing bond prices were negatively affected by the significant
increase in refinancing activity, which dramatically shortened the duration of
these bonds as homeowners paid off their higher-interest mortgages. We reduced
the portfolio's exposure to this sector significantly and, for the six-month
period ended January 31, 2004, the Fund outperformed its Lipper category average
return of +9.22%.

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section
included in this report. As a closed-end fund, the Fund's shares may trade in
the secondary market at a premium or discount to the Fund's net asset value. As
a result, total investment returns based on changes in the market value of the
Fund's Common Stock can vary significantly from total investment return based on
changes in the Fund's net asset value.

What changes were made to the portfolio during the period?

Changes during the year generally followed three themes. First, we replaced
bonds that were called during the period, including the single-family housing
bonds mentioned earlier. In making new purchases, we moved further out on the
yield curve to the 25-year range. These maturities were favored because the
municipal yield curve flattened out past this range, meaning there was no
significant yield to be gained by extending further. We also continued to favor
premium-coupon bonds when making new purchases. Second, given their heavy
supply, we took the opportunity to purchase California municipal bonds at
relatively inexpensive levels. Our goal is to achieve generous returns on these
bonds when conditions improve in the state and prices return to their
historically higher levels -- that is, to buy low and sell high as supply
dwindles and demand increases. The third change was a move to a slightly
defensive market position late in the period in recognition of certain robust
economic indicators. While strong payroll growth has yet to materialize, recent
indicators point to continued progress in this area. A defensive stance on
interest rates should help us to protect the portfolio's net asset value when
interest rates rise.

We generally maintained the Fund's fully invested position during the period in
an effort to enhance shareholder income. As short-term interest rates stayed at
historic lows, the cost of holding cash reserves would have been relatively
high. Given the low level of short-term interest rates, the Fund's borrowing
costs also remained at or below 1%. These attractive funding levels, in
combination with a positively sloped yield curve, provided a generous income
benefit to the Common Stock shareholder from the leveraging of Preferred Stock.
While further material declines in short-term interest rates are not expected,
neither is an imminent increase in rates. We believe that the Fund's borrowing
costs should remain at current levels for the foreseeable future. However,
should the spread between short-term and long-term interest rates narrow, the
benefits of leveraging will decline and, as a result, reduce the yield on the
Fund's Common Stock. At the end of the period, the Fund's leverage amount, based
on AMPS, was 30.16% of total assets. (For a more complete explanation of the
benefits and risks of leveraging, see page 2 of this report to shareholders.)

How would you characterize the portfolio's position at the close of the period?

At the end of the period, the portfolio remained essentially fully invested in
high-quality municipal bonds. The fully invested position should continue to
provide a material benefit to the Common Stock shareholder as short-term
interest rates stay near historic lows. Additionally, the Fund remained
overweight in premium-coupon bonds, favoring maturities in the 25-year range.
The Fund is positioned in a slightly defensive manner, which we believe prepares
it for favorable investment results in a stable-to-rising interest rate
environment.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniEnhanced Fund, Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as amended, 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 MEN. 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 last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained by the
Fund's pricing service from one or more dealers that make markets in the
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). Swap agreements are valued by quoted fair values
received daily by the Fund from the counterparty. Short-term investments with a
remaining maturity 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 both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. 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. 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 may write covered call options and purchase call and 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 reflecting
      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.

o     Forward interest rate swaps--The Fund may enter into forward interest rate
      swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

Notes to Financial Statements (continued)

(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. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(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 .50% of the Fund's average weekly net assets, including assets
acquired from the issuance of Preferred Stock. For the year ended January 31,
2004, FAM reimbursed the Fund in the amount of $12,279.

Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of
FAM, received $2,000 in commissions on the execution of portfolio security
transactions for the Fund for the year ended January 31, 2004.

For the year ended January 31, 2004, the Fund reimbursed FAM $10,454 for certain
accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

year ended January 31, 2004 were $243,242,361 and $255,432,945, respectively.

                                              ================================

share, all of which were initially classified as Common Stock. The Board of
Directors is authorized, however, to reclassify any unissued shares of stock
without the approval of the holders of Common Stock.

Preferred Stock

Auction Market Preferred Stock are shares of Preferred Stock of the Fund, with a
par value of $.025 per share and a liquidation preference of $25,000 per share,
plus accrued and unpaid dividends, that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive dividend period for
each series. The yields in effect at January 31, 2004 were as follows: Series A,
..97%; Series B, .97%; and Series C, .70%.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from .25% to .50%, calculated on the proceeds of each
auction. For the year ended January 31, 2004, MLPF&S received $148,355 as
commissions.

The tax character of distributions paid during the fiscal years ended January

--------------------------------------------------------------------------------
                                                  1/31/2004           1/31/2003

Total distributions ....................         $22,774,911         $22,815,272
                                                 ===============================

As of January 31, 2004, the components of accumulated earnings on a tax basis
were as follows:

-----------------------------------------------------------------------------
Undistributed tax-exempt income--net ....................        $  5,624,362
Undistributed long-term capital gains--net ..............                  --
                                                                 ------------
Total undistributed earnings--net .......................           5,624,362
Capital loss carryforward ...............................         (15,033,608)*
Unrealized gains--net ...................................          30,756,879**
                                                                 ------------
Total accumulated earnings--net .........................        $ 21,347,633
                                                                 ============

*     On January 31, 2004, the Fund had a net capital loss carryforward of
      $15,033,608, of which $4,572,805 expires in 2008, $8,505,599 expires in
      2009 and $1,955,204 expires in 2011. This amount will be available to
      offset like amounts of any future taxable gains.
**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on straddles and the
      difference between book and tax amortization methods for premiums and
      discounts on fixed income securities.

Independent Auditors' Report

To the Shareholders and Board of Directors of
MuniEnhanced Fund, Inc.:

We have audited the accompanying statement of net assets, including the schedule
of investments, of MuniEnhanced Fund, Inc., as of January 31, 2004, and the
related statement of operations for the year then ended, the statements of

These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted

perform the audit to obtain reasonable assurance about whether the financial

disclosures in the financial statements. Our procedures included confirmation of
securities owned as of January 31, 2004, by correspondence with the custodian

Automatic Dividend Reinvestment Plan

The following description of the Fund's Automatic Dividend Reinvestment Plan
(the "Plan") is sent to you annually as required by Federal securities laws.

Pursuant to the Fund's Plan, unless a holder of Common Stock otherwise elects,
all dividend and capital gains distributions will be automatically reinvested by
EquiServe (the "Plan Agent"), as agent for shareholders in administering the
Plan, in additional shares of Common Stock of the Fund. Holders of Common Stock
who elect not to participate in the Plan will receive all distributions in cash
paid by check mailed directly to the shareholder of record (or, if the shares
are held in street or other nominee name then to such nominee) by EquiServe, as
dividend paying agent. Such participants may elect not to participate in the
Plan and to receive all distributions of dividends and capital gains in cash by
sending written instructions to EquiServe, as dividend paying agent, at the
address set forth below. Participation in the Plan is completely voluntary and
may be terminated or resumed at any time without penalty by written notice if
received by the Plan Agent not less than ten days prior to any dividend record
date; otherwise such termination will be effective with respect to any
subsequently declared dividend or distribution.

Whenever the Fund declares an income dividend or capital gains distribution
(collectively referred to as "dividends") payable either in shares or in cash,
non-participants in the Plan will receive cash and participants in the Plan will
receive the equivalent in shares of Common Stock. The shares will be acquired by
the Plan Agent for the participant's account, depending upon the circumstances
described below, either (i) through receipt of additional unissued but
authorized shares of Common Stock from the Fund ("newly issued shares") or (ii)
by purchase of outstanding shares of Common Stock on the open market
("open-market purchases") on the New York Stock Exchange or elsewhere. If on the
payment date for the dividend, the net asset value per share of the Common Stock
is equal to or less than the market price per share of the Common Stock plus
estimated brokerage commissions (such conditions being referred to herein as
"market premium"), the Plan Agent will invest the dividend amount in newly
issued shares on behalf of the participant. The number of newly issued shares of
Common Stock to be credited to the participant's account will be determined by
dividing the dollar amount of the dividend by the net asset value per share on
the date the shares are issued, provided that the maximum discount from the then
current market price per share on the date of issuance may not exceed 5%. If on
the dividend payment date the net asset value per share is greater than the
market value (such condition being referred to herein as "market discount"), the
Plan Agent will invest the dividend amount in shares acquired on behalf of the
participant in open-market purchases.

In the event of a market discount on the dividend payment date, the Plan Agent
will have until the last business day before the next date on which the shares
trade on an "ex-dividend" basis or in no event more than 30 days after the
dividend payment date (the "last purchase date") to invest the dividend amount
in shares acquired in open-market purchases. It is contemplated that the Fund
will pay monthly income dividends. Therefore, the period during which
open-market purchases can be made will exist only from the payment date on the
dividend through the date before the next "ex-dividend" date, which typically
will be approximately ten days. If, before the Plan Agent has completed its
open-market purchases, the market price of a share of Common Stock exceeds the
net asset value per share, the average per share purchase price paid by the Plan
Agent may exceed the net asset value of the Fund's shares, resulting in the
acquisitions of fewer shares than if the dividend had been paid in newly issued
shares on the dividend payment date. Because of the foregoing difficulty with
respect to open-market purchases, the Plan provides that if the Plan Agent is
unable to invest the full dividend amount in open-market purchases during the
purchase period or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market purchases and will
invest the uninvested portion of the dividend amount in newly issued shares at
the close of business on the last purchase date determined by dividing the
uninvested portion of the dividend by the net asset value per share.

The Plan Agent maintains all shareholders' accounts in the Plan and furnishes
written confirmation of all transactions in the account, including information
needed by shareholders for tax records. Shares in the account of each Plan
participant will be held by the Plan Agent in non-certificated form in the name
of the participant, and each shareholder's proxy will include those shares
purchased or received pursuant to the Plan. The Plan Agent will forward all
proxy solicitation materials to participants and vote proxies for shares held
pursuant to the Plan in accordance with the instructions of the participants.

In the case of shareholders such as banks, brokers or nominees which hold shares
of others who are the beneficial owners, the Plan Agent will administer the Plan
on the basis of the number of shares certified from time to time by the record
shareholders as representing the total amount registered in the record
shareholder's name and held for the account of beneficial owners who are to
participate in the Plan.

There will be no brokerage charges with respect to shares issued directly by the
Fund as a result of dividends or capital gains distributions payable either in
shares or in cash. However, each participant will pay a pro rata share of
brokerage commissions incurred with respect to the Plan Agent's open-market
purchases in connection with the reinvestment of dividends.

The automatic reinvestment of dividends and distributions will not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends.

Shareholders participating in the Plan may receive benefits not available to
shareholders not participating in the Plan. If the market price plus commissions
of the Fund's shares is above the net asset value, participants in the Plan will
receive shares of the Fund at less than they could otherwise purchase them and
will have shares with a cash value greater than the value of any cash
distribution they would have received on their shares. If the market price plus
commissions is below the net asset value, participants will receive
distributions in shares with a net asset value greater than the value of any
cash distribution they would have received on their shares. However, there may
be insufficient shares available in the market to make distributions in shares
at prices below the net asset value. Also, since the Fund does not redeem
shares, the price on resale may be more or less than the net asset value.

The value of shares acquired pursuant to the Plan will generally be excluded
from gross income to the extent that the cash amount reinvested would be
excluded from gross income. If, when the Fund's shares are trading at a premium
over net asset value, the Fund issues shares pursuant to the Plan that have a
greater fair market value than the amount of cash reinvested, it is possible
that all or a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable distribution. If
the discount is viewed as a taxable distribution, it is also possible that the
taxable character of this discount would be allocable to all the shareholders,
including shareholders who do not participate in the Plan. Thus, shareholders
who do not participate in the Plan might be required to report as ordinary
income a portion of their distributions equal to their allocable share of the
discount.

Experience under the Plan may indicate that changes are desirable. Accordingly,
the Fund reserves the right to amend or terminate the Plan. There is no direct
service charge to participants in the Plan; however, the Fund reserves the right
to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Agent at
EquiServe, P.O. Box 43010, Providence, RI 02940-3010, Telephone: 800-426-5523.

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 stable level of dividend distributions, 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 Net Assets, which
comprises part of the financial information included in this report.

MuniEnhanced Fund, Inc. seeks to provide shareholders with as high a level of
current income exempt from Federal income taxes as is consistent with its
investment policies by investing primarily in a portfolio of long-term,
investment grade municipal obligations, the interest on which is exempt from
Federal income taxes in the opinion of the bond counsel to the issuer.

This report, including the financial information herein, is transmitted to
shareholders of MuniEnhanced Fund, Inc. for their information. It is not a
prospectus. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred Stock to
provide the Common Stock shareholders with a potentially higher rate of return.
Leverage creates risks for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of shares of the
Common Stock, and the risk that fluctuations in the short-term dividend rates of
the Preferred Stock may affect the yield to Common Stock shareholders.

         (b) Audit-Related Fees - Current Year -- $5,600   Prior Year -- $10,400
                                  The nature of the services include assurance
                                  and related services reasonably related to the
                                  performance of the audit of financial
                                  statements not included in Audit Fees above.

         (c) Tax Fees - Current Year -- $5,610          Prior Year -- $4,800

         (e)(1) The registrant's audit committee (the "Committee") has adopted
                policies and procedures with regard to the pre-approval of
                services. Audit, audit-related and tax compliance services
                provided to the registrant on an annual basis require specific
                pre-approval by the Committee. The Committee also must approve
                other non-audit services provided to the registrant and those
                non-audit services provided to the registrant's affiliated
                service providers that relate directly to the operations and the
                financial reporting of the registrant. Certain of these
                non-audit services that the Committee believes are a) consistent
                with the SEC's auditor independence rules and b) routine and
                recurring services that will not impair the independence of the
                independent accountants may be approved by the Committee without
                consideration on a specific case-by-case basis ("general
                pre-approval"). However, such services will only be deemed
                pre-approved provided that any individual project does not
                exceed $5,000 attributable to the registrant or $50,000 for the
                project as a whole. Any proposed services exceeding the
                pre-approved cost levels will require specific pre-approval by
                the Committee, as will any other services not subject to general
                pre-approval (e.g., unanticipated but permissible services). The
                Committee is informed of each service approved subject to
                general pre-approval at the next regularly scheduled in-person
                board meeting.

         (g) Current Year -- $18,176,900        Prior Year -- $17,134,248

         (h) The registrant's audit committee has considered that the provision
             of non-audit services that were rendered to the registrant's
             investment adviser and any entity controlling, controlled by, or
             under common control with the investment adviser that provides
             ongoing services to the registrant that were not pre-approved
             pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is
             compatible with maintaining the principal accountant's
             independence.

Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End
         Management Investment Companies -

         Proxy Voting Policies and Procedures

         Each Fund's Board of Directors/Trustees has delegated to Merrill Lynch
         Investment Managers, L.P. and/or Fund Asset Management, L.P. (the
         "Investment Adviser") authority to vote all proxies relating to the
         Fund's portfolio securities. The Investment Adviser has adopted
         policies and procedures ("Proxy Voting Procedures") with respect to the
         voting of proxies related to the portfolio securities held in the
         account of one or more of its clients, including a Fund. Pursuant to
         these Proxy Voting Procedures, the Investment Adviser's primary
         objective when voting proxies is to make proxy voting decisions solely
         in the best interests of each Fund and its shareholders, and to act in
         a manner that the Investment Adviser believes is most likely to enhance
         the economic value of the securities held by the Fund. The Proxy Voting
         Procedures are designed to ensure that the Investment Adviser considers
         the interests of its clients, including the Funds, and not the
         interests of the Investment Adviser, when voting proxies and that real
         (or perceived) material conflicts that may arise between the Investment
         Adviser's interest and those of the Investment Adviser's clients are
         properly addressed and resolved.

         In order to implement the Proxy Voting Procedures, the Investment
         Adviser has formed a Proxy Voting Committee (the "Committee"). The
         Committee is comprised of the Investment Adviser's Chief Investment
         Officer (the "CIO"), one or more other senior investment professionals
         appointed by the CIO, portfolio managers and investment analysts
         appointed by the CIO and any other personnel the CIO deems appropriate.
         The Committee will also include two non-voting representatives from the
         Investment Adviser's Legal department appointed by the Investment
         Adviser's General Counsel. The Committee's membership shall be limited
         to full-time employees of the Investment Adviser. No person with any
         investment banking, trading, retail brokerage or research
         responsibilities for the Investment Adviser's affiliates may serve as a
         member of the Committee or participate in its decision making (except
         to the extent such person is asked by the Committee to present
         information to the Committee, on the same basis as other interested
         knowledgeable parties not affiliated with the Investment Adviser might
         be asked to do so). The Committee determines how to vote the proxies of
         all clients, including a Fund, that have delegated proxy voting
         authority to the Investment Adviser and seeks to ensure that all votes
         are consistent with the best interests of those clients and are free
         from unwarranted and inappropriate influences. The Committee
         establishes general proxy voting policies for the Investment Adviser
         and is responsible for determining how those policies are applied to
         specific proxy votes, in light of each issuer's unique structure,
         management, strategic options and, in certain circumstances, probable
         economic and other anticipated consequences of alternate actions. In so
         doing, the Committee may determine to vote a particular proxy in a
         manner contrary to its generally stated policies. In addition, the
         Committee will be responsible for ensuring that all reporting and
         recordkeeping requirements related to proxy voting are fulfilled.



         The Committee may determine that the subject matter of a recurring
         proxy issue is not suitable for general voting policies and requires a
         case-by-case determination. In such cases, the Committee may elect not
         to adopt a specific voting policy applicable to that issue. The
         Investment Adviser believes that certain proxy voting issues require
         investment analysis - such as approval of mergers and other significant
         corporate transactions - akin to investment decisions, and are,
         therefore, not suitable for general guidelines. The Committee may elect
         to adopt a common position for the Investment Adviser on certain proxy
         votes that are akin to investment decisions, or determine to permit the
         portfolio manager to make individual decisions on how best to maximize
         economic value for a Fund (similar to normal buy/sell investment
         decisions made by such portfolio managers). While it is expected that
         the Investment Adviser will generally seek to vote proxies over which
         the Investment Adviser exercises voting authority in a uniform manner
         for all the Investment Adviser's clients, the Committee, in conjunction
         with a Fund's portfolio manager, may determine that the Fund's specific
         circumstances require that its proxies be voted differently.

         To assist the Investment Adviser in voting proxies, the Committee has
         retained Institutional Shareholder Services ("ISS"). ISS is an
         independent adviser that specializes in providing a variety of
         fiduciary-level proxy-related services to institutional investment
         managers, plan sponsors, custodians, consultants, and other
         institutional investors. The services provided to the Investment
         Adviser by ISS include in-depth research, voting recommendations
         (although the Investment Adviser is not obligated to follow such
         recommendations), vote execution, and recordkeeping. ISS will also
         assist the Fund in fulfilling its reporting and recordkeeping
         obligations under the Investment Company Act.

         The Investment Adviser's Proxy Voting Procedures also address special
         circumstances that can arise in connection with proxy voting. For
         instance, under the Proxy Voting Procedures, the Investment Adviser
         generally will not seek to vote proxies related to portfolio securities
         that are on loan, although it may do so under certain circumstances. In
         addition, the Investment Adviser will vote proxies related to
         securities of foreign issuers only on a best efforts basis and may
         elect not to vote at all in certain countries where the Committee
         determines that the costs associated with voting generally outweigh the
         benefits. The Committee may at any time override these general policies
         if it determines that such action is in the best interests of a Fund.

From time to time, the Investment Adviser may be required to vote proxies in
respect of an issuer where an affiliate of the Investment Adviser (each, an
"Affiliate"), or a money management or other client of the Investment Adviser
(each, a "Client") is involved. The Proxy Voting Procedures and the Investment
Adviser's adherence to those procedures are designed to address such conflicts
of interest. The Committee intends to strictly adhere to the Proxy Voting
Procedures in all proxy matters, including matters involving Affiliates and
Clients. If, however, an issue representing a non-routine matter that is
material to an Affiliate or a widely known Client is involved such that the
Committee does not reasonably believe it is able to follow its guidelines (or if
the particular proxy matter is not addressed by the guidelines) and vote
impartially, the Committee may, in its discretion for the purposes of ensuring
that an independent determination is reached, retain an independent fiduciary to
advise the Committee on how to vote or to cast votes on behalf of the Investment
Adviser's clients.

         In the event that the Committee determines not to retain an independent
         fiduciary, or it does not follow the advice of such an independent
         fiduciary, the powers of the Committee shall pass to a subcommittee,
         appointed by the CIO (with advice from the Secretary of the Committee),
         consisting solely of Committee members selected by the CIO. The CIO
         shall appoint to the subcommittee, where appropriate, only persons
         whose job responsibilities do not include contact with the Client and
         whose job evaluations would not be affected by the Investment Adviser's
         relationship with the Client (or failure to retain such relationship).
         The subcommittee shall determine whether and how to vote all proxies on
         behalf of the Investment Adviser's clients or, if the proxy matter is,
         in their judgment, akin to an investment decision, to defer to the
         applicable portfolio managers, provided that, if the subcommittee
         determines to alter the Investment Adviser's normal voting guidelines
         or, on matters where the Investment Adviser's policy is case-by-case,
         does not follow the voting recommendation of any proxy voting service
         or other independent fiduciary that may be retained to provide research
         or advice to the Investment Adviser on that matter, no proxies relating
         to the Client may be voted unless the Secretary, or in the Secretary's
         absence, the Assistant Secretary of the Committee concurs that the
         subcommittee's determination is consistent with the Investment
         Adviser's fiduciary duties



         In addition to the general principles outlined above, the Investment
         Adviser has adopted voting guidelines with respect to certain recurring
         proxy issues that are not expected to involve unusual circumstances.
         These policies are guidelines only, and the Investment Adviser may
         elect to vote differently from the recommendation set forth in a voting
         guideline if the Committee determines that it is in a Fund's best
         interest to do so. In addition, the guidelines may be reviewed at any
         time upon the request of a Committee member and may be amended or
         deleted upon the vote of a majority of Committee members present at a
         Committee meeting at which there is a quorum.

         The Investment Adviser has adopted specific voting guidelines with
         respect to the following proxy issues:

o     Proposals related to the composition of the Board of Directors of issuers
      other than investment companies. As a general matter, the Committee
      believes that a company's Board of Directors (rather than shareholders) is
      most likely to have access to important, nonpublic information regarding a
      company's business and prospects, and is therefore best-positioned to set
      corporate policy and oversee management. The Committee, therefore,
      believes that the foundation of good corporate governance is the election
      of qualified, independent corporate directors who are likely to diligently
      represent the interests of shareholders and oversee management of the
      corporation in a manner that will seek to maximize shareholder value over
      time. In individual cases, the Committee may look at a nominee's history
      of representing shareholder interests as a director of other companies or
      other factors, to the extent the Committee deems relevant.

o     Proposals related to the selection of an issuer's independent auditors. As
      a general matter, the Committee believes that corporate auditors have a
      responsibility to represent the interests of shareholders and provide an
      independent view on the propriety of financial reporting decisions of
      corporate management. While the Committee will generally defer to a
      corporation's choice of auditor, in individual cases, the Committee may
      look at an auditors' history of representing shareholder interests as
      auditor of other companies, to the extent the Committee deems relevant.

o     Proposals related to management compensation and employee benefits. As a
      general matter, the Committee favors disclosure of an issuer's
      compensation and benefit policies and opposes excessive compensation, but
      believes that compensation matters are normally best determined by an
      issuer's board of directors, rather than shareholders. Proposals to
      "micro-manage" an issuer's compensation practices or to set arbitrary
      restrictions on compensation or benefits will, therefore, generally not be
      supported.

o     Proposals related to requests, principally from management, for approval
      of amendments that would alter an issuer's capital structure. As a general
      matter, the Committee will support requests that enhance the rights of
      common shareholders and oppose requests that appear to be unreasonably
      dilutive.

o     Proposals related to requests for approval of amendments to an issuer's
      charter or by-laws. As a general matter, the Committee opposes poison pill
      provisions.

o     Routine proposals related to requests regarding the formalities of
      corporate meetings.



o     Proposals related to proxy issues associated solely with holdings of
      investment company shares. As with other types of companies, the Committee
      believes that a fund's Board of Directors (rather than its shareholders)
      is best-positioned to set fund policy and oversee management. However, the
      Committee opposes granting Boards of Directors authority over certain
      matters, such as changes to a fund's investment objective, that the
      Investment Company Act envisions will be approved directly by
      shareholders.

o     Proposals related to limiting corporate conduct in some manner that
      relates to the shareholder's environmental or social concerns. The
      Committee generally believes that annual shareholder meetings are
      inappropriate forums for discussion of larger social issues, and opposes
      shareholder resolutions "micromanaging" corporate conduct or requesting
      release of information that would not help a shareholder evaluate an
      investment in the corporation as an economic matter. While the Committee
      is generally supportive of proposals to require corporate disclosure of
      matters that seem relevant and material to the economic interests of
      shareholders, the Committee is generally not supportive of proposals to
      require disclosure of corporate matters for other purposes.
