Announcement to Shareholders

On February 15, 2006, BlackRock, Inc. ("BlackRock") and Merrill Lynch & Co.,
Inc. ("Merrill Lynch") entered into an agreement to contribute Merrill Lynch's
investment management business, Merrill Lynch Investment Managers, L.P. and
certain affiliates (including Fund Asset Management, L.P. and Merrill Lynch
Investment Managers International Limited), to BlackRock to create a new
independent company that will be one of the world's largest asset management
firms with over $1 trillion in assets under management (based on combined assets
under management as of March 31, 2006). The transaction is expected to close in
the third quarter of 2006, at which time the new company will operate under the

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.

A Letter From the President

Dear Shareholder

You may be aware that changes are on the horizon at Merrill Lynch Investment
Managers ("MLIM"). On February 15, 2006, Merrill Lynch announced plans to
combine the firm's investment advisory business, including MLIM, with another
highly regarded investment manager -- BlackRock, Inc. ("BlackRock").

We believe this merger of asset management strength will benefit our investors.
MLIM is a leading investment management organization with over $576 billion in
assets under management globally and 2,757 employees in 17 countries. It offers
over 100 investment strategies in vehicles ranging from mutual funds to
institutional portfolios. BlackRock is one of the largest publicly traded
investment management firms in the United States with $463.1 billion in assets
under management and 1,839 employees. It manages assets on behalf of
institutional and individual investors worldwide through a variety of equity,
fixed income, liquidity and alternative investment products.

At the completion of the transaction, which is expected in the third quarter of
this year, the resultant firm will be a top-10 investment manager worldwide with
over $1 trillion in assets under management.* The combined company will provide
a wider selection of high-quality investment solutions across a range of asset
classes and investment styles. MLIM and BlackRock possess complementary
capabilities that together create a well-rounded organization uniting some of
the finest money managers in the industry. At the same time, the firms share
similar values and beliefs -- they are focused on delivering excellence on
behalf of clients, and both make investment performance their single most
important mission. In short, the merger only reinforces our commitment to
shareholders.

Most of MLIM's investment products -- including mutual funds, separately managed
accounts, annuities and variable insurance funds -- eventually will carry the
"BlackRock" name. As a shareholder in one or more MLIM-advised mutual funds, you
will receive a proxy package in the coming weeks in connection with this
transaction. After you receive this information, should you have any questions
or concerns, do not hesitate to contact your financial advisor.

As always, we thank you for entrusting us with your investment assets, and we
look forward to continuing to serve your investment needs with even greater
strength and scale as the new BlackRock.

                                          Sincerely,


                                          /s/ Robert C. Doll, Jr.

                                          Robert C. Doll, Jr.
                                          President and Chief Investment Officer
                                          Merrill Lynch Investment Managers

*     $1.039 trillion in assets under management as of March 31, 2006.

      Data, including assets under management, are as of March 31, 2006.

A Discussion With Your Fund's Portfolio Manager

      The Fund maintained an above-average distribution rate throughout the
period, and our commitment to providing shareholders with attractive income
continues to drive portfolio activity.

Describe the recent market environment relative to municipal bonds.

Long-term bond yields rose sharply during the six-month period ended April 30,
2006, with much of the increase occurring in March and April 2006. Bond prices,
which move opposite of yields, declined. Bond prices were pressured as investors
focused on solid economic growth, both globally and in the United States, and
renewed inflationary pressures deriving from rising commodity prices. First
quarter 2006 gross domestic product growth was recently estimated at 4.8%, well
above the 1.7% rate recorded in the fourth quarter of 2005.

The Federal Reserve Board (the Fed) continued to raise short-term interest rates
at each of its meetings during the period, bringing the federal funds target
rate to 4.75% at period-end, and to 5% on May 10. In response, the Treasury
curve continued to flatten, with short-term interest rates rising more than
longer-term interest rates. Over the past six months, 30-year U.S. Treasury bond
yields rose 41 basis points (.41%) to 5.17% and 10-year U.S. Treasury note
yields rose 50 basis points to 5.07%, the highest level since May 2002.

While the municipal yield curve also flattened during the period, the market's
strong technical position provided significant price support. This allowed
municipal bond prices to improve slightly or decline much less than those of
their taxable counterparts. As measured by Municipal Market Data, yields on
AAA-rated issues maturing in 30 years fell six basis points to 4.53%, while
yields on AAA-rated issues maturing in 10 years rose 16 basis points to 4.08%.

For the most part, the tax-exempt market's recent outperformance has been
fostered by a dramatic decline in new bond issuance so far in 2006. In 2005,
more than $408 billion in new long-term tax-exempt bonds was underwritten, a new
annual record and an increase of more than 13% compared to 2004. Over the past
six months, $170 billion in long-term municipal bonds was issued, a decline of
8.6% versus the same period a year earlier. The record new issuance in 2005 was
largely triggered by a 47% increase in refunding activity as issuers took
advantage of historically low bond yields and a flattening yield curve to
refinance outstanding higher-couponed debt. Year-to-date through April 2006,
refunding issuance declined more than 55% relative to the first four months of
2005. This decline already has led some analysts to reduce their forecasts for
2006 new issuance from the $350 billion - $370 billion range to the $300 billion
- - $325 billion range. Lower annual issuance would further solidify the
tax-exempt market's already positive technical position.

The tax-exempt market has continued to enjoy strong investor demand. As reported
by the Investment Company Institute, long-term municipal bond funds received net
new monies of $5.0 billion in 2005 -- a sharp reversal from the $3.7 billion
outflow in 2004. During the first quarter of 2006, tax-exempt mutual funds
received over $9.3 billion, slightly higher than the $8.9 billion inflow during
the same period in 2005. Recent statistics from AMG Data Services indicate that,
thus far in 2006, weekly cash flows into long-term municipal bond funds averaged
over $300 million, a significant improvement from the weekly average of $65
million in December 2005.

Looking ahead, the fundamentals for the tax-exempt bond market appear favorable,
and continued positive cash flows are anticipated. Given their attractive yields
relative to comparable U.S. Treasury bonds, and the prospects for reduced
issuance in 2006, we believe municipal bonds could enjoy solid results in the
coming months.

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

For the six-month period ended April 30, 2006, the Common Stock of MuniVest Fund
II, Inc. had net annualized yields of 7.03% and 6.54%, based on a period-end per
share net asset value of $14.97 and a per share market price of $16.09,
respectively, and $.522 per share income dividends. Over the same period, the
total investment return on the Fund's Common Stock was +2.43%, based on a change
in per share net asset value from $15.13 to $14.97, and assuming reinvestment of
all distributions.

The Fund's total return, based on net asset value, lagged the +2.60% average
return of its comparable Lipper category of General Municipal Debt Funds
(Leveraged). (Funds in this Lipper category invest primarily in municipal debt
issues rated in the top four credit-rating categories. These funds can be
leveraged via use of debt, preferred equity and/or reverse repurchase
agreements.)


4       MUNIVEST FUND II, INC.                          APRIL 30, 2006


Fund performance benefited from our neutral interest rate exposure and the
strong performance of its lower-rated holdings, which continued to outpace the
broader market during the six-month period. These lower-rated securities also
greatly contributed to the Fund's attractive distribution yield. The modest
underperformance on a total return basis is largely attributable to the
portfolio's considerable exposure to the intermediate sector of the municipal
yield curve, an area that underperformed as the curve flattened. The Fund's
exposure to the intermediate sector primarily results from both its derivative
position and the natural maturation of the portfolio. That is, as time
progresses, many of the Fund's holdings are prerefunded to shorter call dates
while other issues become priced to shorter and shorter call dates, resulting in
the increased exposure to intermediate maturities. Nevertheless, we retained
many of these bonds in the portfolio, as they provide a meaningful income
benefit and their sale could result in material taxable gains as well as
declines in the Fund's dividend stream.

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 of
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 returns based on
changes in the Fund's net asset value.

What changes were made to the portfolio during the period?

Given the aforementioned decline in new issuance during the past six months,
attractive trading opportunities have been limited. Portfolio activity has been
largely focused on the reinvestment of coupon income and the proceeds from bond
calls.

In terms of new purchases, we have recently targeted AA-rated and A-rated
revenue bonds, particularly in New York where new issuance trends have been
consistently stronger than national levels. The Fund's overall credit quality
profile remained essentially unchanged during the period, with more than 56% of
the portfolio's net assets rated A or higher at April month-end.

For the six-month period ended April 30, 2006, the Fund's Auction Market
Preferred Stock (AMPS) had average yields of 3.02% for Series A, 3.40% for
Series B, 3.01% for Series C and 3.01% for Series D. The Fed raised the
short-term interest rate target 100 basis points during the period, and this
continued to affect the Fund's borrowing costs. We would expect additional
increases in the cost of funds to be more limited as the Fed nears a pause in
its monetary tightening campaign. Despite interest rate increases during the
period, the tax-exempt yield curve maintained a positive slope, allowing us to
borrow at a lower rate than where we invest. This continued to generate an
income benefit to the holders of Common Stock from the leveraging of Preferred
Stock. 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, due to AMPS, was 36.72% of total net assets, before the
deduction of Preferred Stock. (For a more complete explanation of the benefits
and risks of leveraging, see page 6 of this report to shareholders.)

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

We recently adopted a more positive stance on the municipal market. After 16
consecutive interest rate hikes, the Fed may be nearing a pause in its monetary
tightening campaign. We would expect the end of Fed tightening, combined with
modest economic growth and muted inflationary pressures, to promote a gradual
improvement in tax-exempt bond prices later this year, underpinning our more
constructive outlook. Conversely, we would view accelerated economic activity
and/or rising wage pressures as signals to return to a more defensive
positioning.

Overall, we intend to maintain the Fund's fully invested stance as we seek to
enhance shareholder income. Portfolio activity in the months ahead is likely to
be driven by our efforts to maintain the Fund's already attractive distribution
yield.

The Benefits and Risks of Leveraging

MuniVest Fund II, 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.

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 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 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 such securities. As of April 30, 2006, the percentage of the Fund's
total net assets invested in inverse floaters was 10.70%, before the deduction
of Preferred Stock.

Swap Agreements

The Fund may 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. Swap agreements involve the risk that the party with whom the
Fund has entered into the swap will default on its obligation to pay the Fund
and the risk that the Fund will not be able to meet its obligations to pay the
other party to the agreement.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniVest Fund II, 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 U.S.
generally accepted accounting principles, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to present a fair statement of the
results for the interim period. All such adjustments are of a normal, recurring
nature. The Fund determines and makes available for publication the net asset
value of its Common Stock on a daily basis. The Fund's Common Stock shares are
listed on the New York Stock Exchange under the symbol MVT. 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 ("OTC") markets and are valued at the last available bid price
in the OTC market or on the basis of values as obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general direction
of the Board of Directors. Such valuations and procedures are reviewed
periodically by the Board of Directors of the Fund. 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 OTC 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's pricing service.
Short-term investments with a remaining maturity of 60 days or less are valued
at amortized cost, which approximates market value, under which method the
investment is valued at cost and any premium or discount is amortized on a
straight line basis to maturity. Investments in open-end investment companies
are valued at their net asset value each business day. Securities and other
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.

(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 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.

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 and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

(f) Offering costs -- Direct expenses relating to the public offering of the
Fund's Preferred Stock were charged to capital at the time of issuance of the
shares.

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
proceeds from the issuance of Preferred Stock. The Investment Adviser has agreed
to reimburse its management fee by the amount of the management fees the Fund
pays to FAM indirectly through its investment in Merrill Lynch Institutional
Tax-Exempt Fund. For the six months ended April 30, 2006, FAM reimbursed the
Fund in the amount of $250.

In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an
affiliate of FAM, received $1,000 in commissions on the execution of portfolio
security transactions for the Fund for the six months ended April 30, 2006.

For the six months ended April 30, 2006, the Fund reimbursed FAM $5,098 for
certain accounting services.

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

In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
contribute ML & Co.'s investment management business, including FAM, to the
investment management business of BlackRock, Inc. The transaction is expected to
close in the third quarter of 2006.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended April 30, 2006 were $160,657,088 and $161,610,110, respectively.

4. Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of stock, including Preferred
Stock, par value $.10 per 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 approval of holders of Common Stock.

Common Stock

Shares issued and outstanding during the six months ended April 30, 2006 and the
year ended October 31, 2005 increased by 64,795 and 126,778 as a result of
dividend reinvestment, respectively.

Preferred Stock

Auction Market Preferred Stock are shares of Preferred Stock of the Fund, with a
par value of $.05 per share on Series A Shares, Series B Shares and Series C
Shares, and $.10 per share on Series D Shares. In addition, there is 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 periods. The yields in effect at April 30, 2006
were as follows: Series A, 3.20%; Series B, 3.37%; Series C, 3.33%; and Series
D, 3.75%.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from .25% to .375%, calculated on the proceeds of each
auction. For the six months ended April 30, 2006, MLPF&S earned $119,678 as
commissions.

$12,488,454, of which $3,730,020 expires in 2007 and $8,758,434 expires in 2008.

MuniVest Fund II, 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 and prudent investment management by investing primarily in
a portfolio of long-term, investment grade municipal obligations the interest on
which, in the opinion of bond counsel to the issuer, is exempt from federal
income taxes.

This report, including the financial information herein, is transmitted to
shareholders of MuniVest Fund II, 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.
