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.

Announcement of Annual Stockholders Meeting

The Fund has determined that its annual stockholders meeting originally
scheduled to be held in April 2007 will be postponed until and will be held in
June 2007. Proposals of stockholders intended to be presented at the meeting
must be received by the Fund by February 15, 2007 for inclusion in the Fund's
proxy statement and form of proxy for that meeting. The persons named as proxies
in the proxy materials for the Fund's 2007 annual meeting of stockholders may
exercise discretionary authority with respect to any stockholder proposal
presented at such meeting if written notice of such proposal has not been
received by the Fund by April 1, 2007. Written proposals and notices should be
sent to the Secretary of the Fund, 800 Scudders Mill Road, Plainsboro, New
Jersey 08536.

A Letter to Shareholders

Dear Shareholder

Ten months into 2006, we are able to say it has been an interesting year for
investors. After a volatile start and far-reaching mid-year correction, the
financial markets regained some positive momentum through late summer and fall.
For the six- and 12-month periods ended October 31, 2006, most major market
indexes managed to post positive returns:

The Federal Reserve Board (the Fed), after raising the target short-term
interest rate 17 times between June 2004 and June 2006, finally opted to pause
on August 8, 2006. This left the federal funds rate at 5.25%, where it remained
through the September and October Fed meetings. In interrupting its two-year
rate-hiking campaign, the Fed acknowledged that economic growth is slowing, led
by softness in the housing market. However, the central bankers continue to take
a cautionary position on inflation, despite a decline in energy prices in recent
months. At the time of this writing, the price of oil had settled into the
$60-per-barrel range after reaching nearly $78 per barrel earlier in the year.

Notwithstanding the mid-year correction, equity markets generally found support
in solid corporate earnings reports in the first three quarters of the year.
Overall corporate health, including strong company balance sheets, helped to
sustain robust dividend-distribution, share-buyback and merger-and-acquisition
activity. Many international equity markets fared equally well or better, thanks
in part to higher economic growth rates and low inflation.

In the U.S. bond market, prices declined for much of the year as investors
focused on decent economic activity and inflation concerns. Bond prices began to
improve in late June as the economy showed signs of weakening and inflation
pressures subsided. Notably, the Treasury curve inverted periodically, a
phenomenon typically associated with periods of economic weakness. At the end of
October, the one-month Treasury bill offered the highest yield on the curve at
5.18%, while the 30-year Treasury bond had a yield of 4.72%.

Amid the uncertainty inherent in the financial markets, we encourage you to
review your goals periodically with your financial professional and to make
portfolio changes, as needed. For additional insight and timely "food for
thought" for investors, we also invite you to visit Shareholder magazine at
www.blackrock.com/shareholdermagazine. We are pleased to make our
investor-friendly magazine available to you online. We thank you for trusting
BlackRock with your investment assets, and we look forward to continuing to
serve your investment needs.

                                                         /s/ Robert C. Doll, Jr.

A Discussion With Your Fund's Portfolio Manager

      The Fund's relatively neutral interest rate position and adequate exposure
to lower-rated, higher-yielding issues allowed it to continue distributing one
of the highest dividend yields among its peers.

Describe the recent market environment relative to municipal bonds.

Supported by a positive technical backdrop, municipal bonds managed to
significantly outperform their taxable counterparts for the 12-month period
ended October 31, 2006. Despite considerable volatility, taxable bond yields
were little changed over the past year. Tax-exempt bonds, in the meantime, saw
their yields decline (as prices, which move opposite of yields, rose).

For much of the first half of the fiscal period, longer-maturity U.S. Treasury
bond yields rose (and prices declined) as investors focused on strong U.S.
economic activity and inflationary concerns triggered by rising oil prices. By
mid-May 2006, the yield on 30-year U.S. Treasury bonds had risen more than 70
basis points (.70%) to 5.31%. Bond prices began to improve in late June as
economic activity weakened and inflationary pressures subsided. Bond price
improvement accelerated after the Federal Reserve Board (the Fed) refrained from
raising the target interest rate at its August 8 meeting, a move that occurred
after 17 consecutive interest rate hikes since June 2004. Recent declines in oil
prices, especially gasoline, helped to reverse earlier inflationary concerns and
support higher bond prices. Over the 12-month period, 30-year U.S. Treasury bond
yields fell four basis points to 4.72%, while 10-year Treasury yields rose four
basis points to 4.61%.

Meanwhile, the municipal bond market found support in declining new-issue volume
and increasing investor demand. As reported by Municipal Market Data, yields on
AAA-rated municipal issues maturing in 30 years declined 52 basis points to
4.07% over the past 12 months. Shorter maturities experienced smaller yield
declines, with yields on AAA-rated municipal issues maturing in 10 years falling
28 basis points to 3.64%.

Demand for municipal product by retail and institutional investors has remained
very strong despite the recent decline in bond yields. The strong demand is
reflected in continued flows into long-term, tax-exempt mutual funds. As
reported by the Investment Company Institute, long-term municipal bond funds saw
net new cash inflows of more than $1.3 billion during September 2006, a material
increase from $344 million in July and $283 million in June. During the first
nine months of 2006, long-term tax-exempt bond funds had net new cash flows of
over $9.6 billion, a 43% increase compared to the same period a year earlier.
Recent weekly fund flows, reported by AMG Data, averaged $416 million in October
2006, well above the July average of $247 million and the year-to-date weekly
average of $315 million.

Also supporting municipal bond price improvement has been a decline in new
issuance. In the first 10 months of 2006, more than $295 billion in new
long-term municipal bonds was underwritten, a decline of more than 12.5% versus
the same period a year ago. Notably, after declining for much of the year,
refunding activity increased slightly in October as the lower interest rate
environment sparked an increase in refinancing activity. On a year-to-date
basis, however, refunding activity has declined over 50% relative to last year's
refunding issuance.

Looking ahead, the positive technical framework in the municipal marketplace
suggests that the tax-exempt market should continue to perform well. New supply
is expected to remain manageable and tax-exempt bond yield ratios remain in
their recent range of 86% - 89% of comparable long-term U.S. Treasury yields,
well within their recent historic norms. These ratios argue for continued strong
demand from non-traditional, arbitrage-related accounts, which continue to be
attracted to the municipal bond market given its relatively steep yield curve.
Taken together, these factors suggest that the municipal market is poised to
continue to perform well as we approach year-end.

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

For the 12-month period ended October 31, 2006, the Common Stock of BlackRock
MuniVest Fund II, Inc. (formerly MuniVest Fund II, Inc.) had net annualized
yields of 6.45% and 6.08%, based on a year-end per share net asset value of
$15.35 and a per share market price of $16.29, respectively, and $.990 per share
income dividends. Over the same period, the total investment return on the
Fund's Common Stock was +8.36%, based on a change in per share net asset value
from $15.13 to $15.35, and assuming reinvestment of all distributions.

The Fund's total return, based on net asset value, was competitive with the
+8.42% average return of its comparable Lipper category of General Municipal
Debt Funds (Leveraged).


4       BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006


(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.)

Our strategy of maintaining a relatively neutral interest rate position was a
primary contributor to Fund performance during a period of volatile, but
generally declining, bond yields. The Fund's results also benefited from the
strong performance of its lower-rated holdings, which outpaced the broader
market for much of the fiscal period as credit spreads (versus higher-rated
issues of comparable maturity) continued to tighten. The exposure to
higher-yielding credits, along with maintaining a fully invested portfolio,
contributed to the Fund's above-average distribution yield, making it a
top-yielding fund in the Lipper category for the 12 months ended October 31,
2006.

For the six-month period ended October 31, 2006, the total investment return on
the Fund's Common Stock was +5.79%, based on a change in per share net asset
value from $14.97 to $15.35, and assuming reinvestment of all distributions.

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?

Attractive trading opportunities were limited given the aforementioned decline
in new issuance and low nominal bond yields that characterized the majority of
the annual period.

In making new purchases, we focused on AA-rated and A-rated revenue bonds,
particularly in New York where new issuance trends have been consistently
stronger than those on the national level. Additionally, AA-rated and A-rated
hospital revenue bonds were recent acquisition targets given their incremental
yield and significant market liquidity. The Fund's credit quality profile
remained essentially unchanged, with more than 60% of net assets rated A or
higher at October month-end.

For the six-month period ended October 31, 2006, the Fund's Auction Market
Preferred Stock (AMPS) had average yields of 3.54% for Series A, 3.55% for
Series B, 3.39% for Series C and 3.48% for Series D. The Fed raised short-term
interest rates six times during the 12-month period, but opted to keep the
target rate on hold at 5.25% in August, September and October. As such, the
Fund's borrowing costs began to stabilize and even move slightly lower late in
the period. Despite the Fed's interest rate increases during the period, the
municipal yield curve remained positively sloped and continued to generate an
income benefit to the Common Stock shareholder from the leveraging of Preferred
Stock. However, should the spread between short-term and long-term interest
rates narrow, the benefits of leverage will decline and, as a result, the yield
on the Fund's Common Stock will be reduced. (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?

The Fund ended the annual period in a slightly defensive position with respect
to interest rate risk, as current yield levels appear to be lower than economic
and inflation fundamentals alone would support. Ongoing positive technical
factors -- particularly the significant amount of excess liquidity-driven demand
seen in recent months -- prevent taking a more defensive duration posture.

Moving forward, we will continue to monitor economic trends, particularly the
employment and housing statistics, to ensure the Fund's current structuring is
appropriate. We intend to maintain the Fund's fully invested stance, and we will
avoid accumulating large cash reserve positions in order to enhance shareholder
income. Future portfolio activity also is expected to support our ongoing
efforts to maintain the Fund's higher-than-average distribution yield.

The Benefits and Risks of Leveraging

BlackRock 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 of 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 of October 31, 2006, the Fund's leverage amount, due to Auction Market
Preferred Stock, was 36.08%, before the deduction of Preferred Stock.

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.

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:

On September 29, 2006, MuniVest Fund II, Inc. was renamed BlackRock MuniVest
Fund II, Inc. (the "Fund"). 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. 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. Options
traded in the OTC market are valued at 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 financial futures contracts.
      Financial 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.

o     Swaps -- The Fund may enter into swap agreements, which are OTC contracts
      in which the Fund and a counterparty agree to make periodic net payments
      on a specified notional amount. The net payments can be made for a set
      period of time or may be triggered by a predetermined credit event. The
      net periodic payments


16      BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006


Notes to Financial Statements (continued)

      may be based on a fixed or variable interest rate; the change in market
      value of a specified security, basket of securities, or index; or the
      return generated by a security. These periodic payments received or made
      by the Fund are recorded in the accompanying Statement of Operations as
      realized gains or losses, respectively. Gains or losses are also realized
      upon termination of the swap agreements. Swaps are marked-to-market daily
      and changes in value are recorded as unrealized appreciation
      (depreciation). Risks include changes in the returns of the underlying
      instruments, failure of the counterparties to perform under the contracts'
      terms and the possible lack of liquidity with respect to the swap
      agreements.

(c) Municipal bonds held in trust -- The Fund invests in leveraged residual
certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A
TOB is established by a third party sponsor forming a special purpose entity,
into which the Fund, or an agent on behalf of the Fund, transfers municipal
securities. A TOB typically issues two classes of beneficial interests:
short-term floating rate certificates, which are sold to third party investors,
and residual certificates, which are generally issued to the Fund which made the
transfer or to affiliates of the Fund. The transfer of the municipal securities
to a TOB does not qualify for sale treatment under Statement of Financial
Accounting Standards No. 140 "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities", therefore the municipal
securities deposited into a TOB are presented in the Fund's schedule of
investments and the proceeds from the transaction are reported as a liability
for trust certificates of the Fund. Similarly, proceeds from residual
certificates issued to affiliates, if any, from the transaction are included in
the liability for trust certificates. Interest income from the underlying
security is recorded by the Fund on an accrual basis. Interest expense incurred
on the secured borrowing and other expenses related to remarketing,
administration and trustee services to a TOB are reported as expenses of the
Fund. The floating rate certificates have interest rates that generally reset
weekly and their holders have the option to tender certificates to the TOB for
redemption at par at each reset date. The residual interests held by the Fund
include the right of the Fund (1) to cause the holders of a proportional share
of the floating rate certificates to tender their certificates at par, and (2)
to transfer a corresponding share of the municipal securities from the TOB to
the Fund. At October 31, 2006, the aggregate value of the underlying municipal
securities transferred to TOBs was $90,864,728, the related liability for trust
certificates was $41,300,000 and the range of interest rates was 3.58% to 3.63%.

Financial transactions executed through TOBs generally will under perform the
market for fixed rate municipal bonds in a rising interest rate environment, but
tend to outperform the market for fixed rate bonds when interest rates decline
or remain relatively stable. Should short-term interest rates rise, the Fund's
investment in TOB Residuals likely will adversely affect the Fund's investment
income-net and distributions to shareholders. Fluctuations in the market value
of municipal securities deposited into the TOB may adversely affect the Fund's
net asset value per share.

While the Fund's investment policies and restrictions expressly permit
investments in inverse floating rate securities such as TOB Residuals, they
generally do not allow the Fund to borrow money for purposes of making
investments. The Fund's management believes that the Fund's restrictions on
borrowings do not apply to the secured borrowings deemed to have occurred for
accounting purposes.

(d) 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.

(e) 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.

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

(g) 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.

(h) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
fiscal years beginning after December

15, 2006. The impact on the Fund's financial statements, if any, is currently
being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the implications of
FAS 157. At this time its impact on the Fund's financial statements has not been
determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM") and its affiliates, including Fund Asset
Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent
company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest
in the combined company and The PNC Financial Services Group, Inc. has
approximately a 34% economic and voting interest. The new company operates under
the BlackRock name and is governed by a board of directors with a majority of
independent members.

On August 15, 2006, shareholders of the Fund approved a new Investment Advisory
Agreement with BlackRock Advisors, Inc. (the "Manager"), an indirect, wholly
owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc. was recently
reorganized into a limited liability company and renamed BlackRock Advisors,
LLC. The new Investment Advisory Agreement between the Fund and the Manager
became effective on September 29, 2006. Prior to September 29, 2006, FAM was the
Investment Adviser. The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the
limited partner.

The Manager 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 daily net
assets, including proceeds from the issuance of Preferred Stock. The Manager
(and formerly FAM) has agreed to reimburse its management fee by the amount of
management fees the Fund pays to FAM and/or the Manager indirectly through its
investment in the Merrill Lynch Institutional Tax-Exempt Fund. The
reimbursements were as follows:

--------------------------------------------------------------------------------
          For the Period                                For the Period
        November 1, 2005 to                           September 30, 2006
        September 29, 2006                            to October 31, 2006
          Reimbursement                                 Reimbursement
              to FAM                                    to the Manager
--------------------------------------------------------------------------------
              $250                                            --
================================================================================

In addition, the Manager has entered into a sub-advisory agreement with
BlackRock Investment Management, LLC, an affiliate of the Manager, under which
the Manager pays the Sub-Adviser for services it provides a fee equal to 59% of
the management fee paid by the Fund to the Manager.

The Fund reimbursed FAM and/or the Manager for certain accounting services. The
reimbursements were as follows:

--------------------------------------------------------------------------------
          For the Period                                For the Period
        November 1, 2005 to                           September 30, 2006
        September 29, 2006                            to October 31, 2006
          Reimbursement                                 Reimbursement
              to FAM                                    to the Manager
--------------------------------------------------------------------------------
             $9,771                                          $779
================================================================================

In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a
wholly owned subsidiary of Merrill Lynch, received $1,000 in commissions on the
execution of portfolio security transactions for the Fund for the year ended
October 31, 2006.

Prior to September 29, 2006, certain officers and/or directors of the Funds were
officers and/or directors of Merrill Lynch, FAM, MLIM, and/or PSI.

Commencing September 29, 2006, certain officers and/or directors of the Fund are
officers and/or directors of BlackRock, Inc. or its affiliates.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 2006 were $308,645,192 and $315,403,495, 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 years ended October 31, 2006 and October
31, 2005 increased by 121,589 and 126,778, respectively, as a result of dividend
reinvestment.

Notes to Financial Statements (continued)

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 entitles their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yields in effect at October 31,
2006 were as follows: Series A, 3.50%; Series B, 3.62%; Series C, 3.45%; and
Series D, 3.45%.

Shares issued and outstanding during the year ended October 31, 2006 remained
constant. Shares issued and outstanding during the year ended October 31, 2005
increased by 1,600 shares from the issuance of an additional series of Preferred
Stock.

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 year ended October 31, 2006, MLPF&S earned $243,132 as
commissions.

5. Distributions to Shareholders:

The Fund paid a tax-exempt income dividend to holders of Common Stock in the
amount of $.078000 per share on November 29, 2006 to shareholders of record on
November 14, 2006.

The tax character of distributions paid during the fiscal years ended October
31, 2006 and October 31, 2005 was as follows:

--------------------------------------------------------------------------------
                                                 10/31/2006           10/31/2005
--------------------------------------------------------------------------------
Distributions paid from:
  Tax-exempt income ....................        $25,985,792          $25,570,538
                                                --------------------------------
Total distributions ....................        $25,985,792          $25,570,538
                                                ================================

As of October 31, 2006, the components of accumulated earnings on a tax basis
were as follows:

-----------------------------------------------------------------------------
Undistributed tax-exempt income -- net ..................        $  2,508,605
Undistributed long-term capital gains -- net ............                  --
                                                                 ------------
Total undistributed earnings -- net .....................           2,508,605
Capital loss carryforward ...............................         (10,072,402)*
Unrealized gains -- net .................................          34,179,311**
                                                                 ------------
Total accumulated earnings -- net .......................        $ 26,615,514
                                                                 ============

*     On October 31, 2006, the Fund had a net capital loss carryforward of
      $10,072,402, of which $1,158,684 expires in 2007 and $8,913,718 expires in
      2008. 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 wash sales, the
      tax deferral of losses on straddles, the difference between book and tax
      amortization methods for premiums and discounts on fixed income securities
      and the difference between the book and tax treatment of residual
      interests in tender option bond trusts.

6. Restatement Information:

During the year ended October 31, 2006, the Fund determined that the criteria
for sale accounting in Statement of Financial Accounting Standards No. 140 had
not been met for certain transfers of municipal bonds and that these transfers
should have been accounted for as secured borrowings rather than as sales.
Accordingly, the Fund has restated the financial highlights for the years ended
October 31, 2005, 2004, 2003 and 2002 to give effect to recording the transfers
of the municipal bonds as secured borrowings, including recording interest on
the bonds as interest income and interest on the secured borrowings as interest
expense.

Notes to Financial Statements (concluded)

While the Statements of Net Assets as of October 31, 2005, 2004, 2003 and 2002,
not presented herein, have not been reissued to give effect to the restatement,
the principal effects of the restatement would be to increase investments and
liability for trust certificates by corresponding amounts at each year, with no
effect on previously reported net assets. The Statements of Operations for the
years ended October 31, 2005, 2004, 2003 and 2002, not presented herein, have
not been reissued to give effect to the restatement. However, the principal
effects of the restatement would be to increase interest income and interest
expense and fees by corresponding amounts each year, and, where applicable, to
revise realized gain (loss) on investments -- net, and the change in unrealized
appreciation/depreciation on investments -- net, by corresponding and offsetting
amounts. The Statements of Changes in Net Assets for the years ended October 31,
2004, 2003 and 2002, not presented herein, have not been reissued to give effect
to the restatement, but the principal effects of a restatement, where
applicable, would be to revise previously reported realized gain (loss) -- net,
and change in unrealized appreciation/depreciation-net, by corresponding and
offsetting amounts.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of BlackRock MuniVest Fund II, Inc.:

We have audited the accompanying statement of net assets, including the schedule
of investments, of BlackRock MuniVest Fund II, Inc. (formerly MuniVest Fund II,
Inc.) as of October 31, 2006, and the related statement of operations for the
year then ended, the statements of changes in net assets for each of the two
years in the period then ended and the financial highlights for each of the five
years in the period then ended. 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 the standards of the Public Company
Accounting Oversight Board (United States). 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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2006, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
BlackRock MuniVest Fund II, Inc. as of October 31, 2006, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and its financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

As discussed in Note 6, the financial highlights for the years ended October 31,
2005, 2004, 2003 and 2002 have been restated.

Automatic Dividend Reinvestment Plan

How the Plan Works -- The Fund offers a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by the Fund are
automatically reinvested in additional shares of Common Stock of the Fund. The
Plan is administered on behalf of the shareholders by The Bank of New York (the
"Plan Agent"). Under the Plan, whenever the Fund declares a dividend,
participants in the Plan will receive the equivalent in shares of Common Stock
of the Fund. The Plan Agent will acquire the shares for the participant's
account either (i) through receipt of additional unissued but authorized shares
of the Fund ("newly issued shares") or (ii) by purchase of outstanding shares of
Common Stock on the open market on the New York Stock Exchange or elsewhere. If,
on the dividend payment date, the Fund's net asset value per share is equal to
or less than the market price per share plus estimated brokerage commissions (a
condition often referred to as a "market premium"), the Plan Agent will invest
the dividend amount in newly issued shares. If the Fund's net asset value per
share is greater than the market price per share (a condition often referred to
as a "market discount"), the Plan Agent will invest the dividend amount by
purchasing on the open market additional shares. If the Plan Agent is unable to
invest the full dividend amount in open market purchases, or if the market
discount shifts to a market premium during the purchase period, the Plan Agent
will invest any uninvested portion in newly issued shares. The shares acquired
are credited to each shareholder's account. The amount credited is determined by
dividing the dollar amount of the dividend by either (i) when the shares are
newly issued, the net asset value per share on the date the shares are issued or
(ii) when shares are purchased in the open market, the average purchase price
per share.

Participation in the Plan -- Participation in the Plan is automatic, that is, a
shareholder is automatically enrolled in the Plan when he or she purchases
shares of Common Stock of the Fund unless the shareholder specifically elects
not to participate in the Plan. Shareholders who elect not to participate will
receive all dividend distributions in cash. Shareholders who do not wish to
participate in the Plan, must advise the Plan Agent in writing (at the address
set forth below) that they elect not to participate in the Plan. Participation
in the Plan is completely voluntary and may be terminated or resumed at any time
without penalty by writing to the Plan Agent.

Benefits of the Plan -- The Plan provides an easy, convenient way for
shareholders to make additional, regular investments in the Fund. The Plan
promotes a long-term strategy of investing at a lower cost. All shares acquired
pursuant to the Plan receive voting rights. In addition, 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 for less than they could otherwise
purchase them and with a cash value greater than the value of any cash
distribution they would have received. However, there may not be enough 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.

Plan Fees -- There are no enrollment fees or brokerage fees for participating in
the Plan. The Plan Agent's service fees for handling the reinvestment of
distributions are paid for by the Fund. However, brokerage commissions may be
incurred when the Fund purchases shares on the open market and shareholders will
pay a pro rata share of any such commissions.

Tax Implications -- 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. Therefore, income and
capital gains may still be realized even though shareholders do not receive
cash. 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
market premium, 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 the discount from the market value (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.

Contact Information -- All correspondence concerning the Plan, including any
questions about the Plan, should be directed to the Plan Agent at The Bank of
New York, Church Street Station, P.O. Box 11258, New York, NY 10286-1258,
Telephone: 800-432-8224.

Disclosure of Investment Advisory Agreement

Disclosure of FAM Investment Advisory Agreement

The Board of Directors of the Fund met in May 2006 to consider approval of the
Fund's investment advisory agreement with Fund Asset Management, L.P. ("FAM"),
the Fund's investment adviser at that time.

Activities and Composition of the Board

All but one member of the Board is an independent director, whose only
affiliation with FAM or other Merrill Lynch affiliates was as a director of the
Fund and as a director or trustee of certain other funds advised by FAM or its
affiliates. The Chairman of the Board is also an independent director. New
director nominees are chosen by a Nominating Committee comprised of independent
directors. All independent directors also are members of the Board's Audit
Committee, and the independent directors meet in executive session at each
in-person Board meeting. The Board and the Audit Committee meet in person for at
least two days each quarter and conduct other in-person and telephone meetings
throughout the year, some of which are formal Board meetings and some of which
are informational meetings. The independent counsel to the independent directors
attends all in-person Board and Audit Committee meetings and other meetings at
the independent directors' request.

FAM Investment Advisory Agreement -- Matters Considered by the Board

Every year, the Board considers approval of the Fund's investment advisory
agreement. The Board assesses the nature, scope and quality of the services
provided to the Fund by the personnel of the investment adviser and its
affiliates, including administrative services, shareholder services, oversight
of fund accounting, marketing services and assistance in meeting legal and
regulatory requirements. The Board also receives and assesses information
regarding the services provided to the Fund by certain unaffiliated service
providers.

At various times throughout the year, the Board also considers a range of
information in connection with its oversight of the services provided by the
investment adviser and its affiliates. Among the matters considered are: (a)
fees (in addition to management fees) paid to the investment adviser and its
affiliates by the Fund; (b) Fund operating expenses paid to third parties; (c)
the resources devoted to and compliance reports relating to the Fund's
investment objective, policies and restrictions, and its compliance with its
Code of Ethics and compliance policies and procedures; and (d) the nature, cost
and character of non-investment management services provided by the investment
adviser and its affiliates.

The Board noted its view of FAM as one of the most experienced global asset
management firms and considered the overall services provided by FAM to be of
high quality. The Board also noted its view of FAM as financially sound and well
managed and noted FAM's affiliation with one of America's largest financial
firms. The Board works closely with the investment adviser in overseeing the
investment adviser's efforts to achieve good performance. As part of this
effort, the Board discusses portfolio manager effectiveness and, when
performance is not satisfactory, discusses with the investment adviser taking
steps such as changing investment personnel.

Annual Consideration of Approval by the Board

In the period prior to the Board meeting to consider renewal of the investment
advisory agreement, the Board requests and receives materials specifically
relating to the investment advisory agreement. These materials include (a)
information compiled by Lipper Inc. ("Lipper") on the fees and expenses,
investment performance and leverage of the Fund as compared to a comparable
group of funds as classified by Lipper; (b) information comparing the Fund's
market price with its net asset value per share; (c) a discussion by the Fund's
portfolio management team regarding investment strategies used by the Fund
during its most recent fiscal year; (d) information on the profitability to the
investment adviser and its affiliates of the investment advisory agreement and
other relationships with the Fund; and (e) information provided by the
investment adviser concerning investment advisory fees charged to other retail
closed-end funds under similar investment mandates. The Board also considers
other matters it deems important to the approval process, such as payments made
for services related to the valuation and pricing of Fund portfolio holdings,
the Fund's portfolio turnover statistics, and direct and indirect benefits to
the investment adviser and its affiliates from their relationship with the Fund.
The Board did not identify any particular information as controlling, and each
member of the Board may have attributed different weights to the various items
considered.

Certain Specific Renewal Data

In connection with the most recent renewal of the Fund's investment advisory
agreement with FAM (the "FAM Investment Advisory Agreement") in May 2006, the
independent directors' and the Board's review included the following:


        BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006              23


Disclosure of Investment Advisory Agreement (concluded)

Services Provided by the Investment Adviser -- The Board reviewed the nature,
extent and quality of services provided by FAM, including the investment
advisory services and the resulting performance of the Fund. The Board focused
primarily on FAM's investment advisory services and the Fund's investment
performance. The Board compared Fund performance -- both including and excluding
the effects of the Fund's fees and expenses -- to the performance of a
comparable group of funds as classified by Lipper and the performance of a
relevant index or combination of indexes. While the Board reviews performance
data at least quarterly, consistent with the investment adviser's investment
goals, the Board attaches more importance to performance over relatively long
periods of time, typically three to five years. The Board concluded that the
comparative data indicated that the Fund's performance was competitive.
Considering all these factors, the Board concluded that the Fund's performance
and the nature and quality of the services provided supported the continuation
of the FAM Investment Advisory Agreement.

FAM's Personnel and Investment Process -- The Board reviewed the Fund's
investment objectives and strategies. The Board discussed with FAM's senior
management responsible for investment operations and the senior management of
FAM's municipal investing group the strategies being used to achieve the stated
objectives. Among other things, the Board considered the size, education and
experience of FAM's investment staff, its use of technology, and FAM's approach
to training and retaining portfolio managers and other research, advisory and
management personnel. The Board also reviewed FAM's compensation policies and
practices with respect to the Fund's portfolio managers. The Board also
considered the experience of the Fund's portfolio manager and noted that Mr.
Stuebe has more than 15 years of experience in portfolio management. The Board
considered the extensive experience of FAM and its investment staff in analyzing
and managing the types of investments used by the Fund. The Board concluded that
the Fund benefits from that experience.

Management Fees and Other Expenses -- The Board reviewed the Fund's contractual
management fee rate and actual management fee rate as a percentage of total
assets at common asset levels -- the actual rate includes advisory and
administrative service fees and the effects of any fee waivers -- compared to
the other funds in its Lipper category. The Board also compared the Fund's total
expenses to those of other comparable funds. The Board considered the services
provided to and the fees charged by FAM to other types of clients with similar
investment mandates. The Board determined that the Fund's contractual and actual
management fee rates, as well as total expenses, were competitive with those of
comparable funds. The Board concluded that the Fund's management fee rate and
overall expense ratio were reasonable compared to those of other comparable
funds.

Profitability -- The Board considers the cost of the services provided to the
Fund by the investment adviser and the investment adviser's and its affiliates'
profits relating to the management and distribution of the Fund and the funds
advised by the investment manager and its affiliates. As part of its analysis,
the Board reviewed FAM's methodology in allocating its costs to the management
of the Fund and concluded that there was a reasonable basis for the allocation.
The Board also considered federal court decisions discussing an investment
adviser's profitability and profitability levels considered to be reasonable in
those decisions. The Board concluded that the profits of FAM and its affiliates
were acceptable in relation to the nature and quality of services provided and
given the level of fees and expenses overall.

Economies of Scale -- The Board considered the extent to which economies of
scale might be realized as the assets of the Fund increase and whether there
should be changes in the management fee rate or structure in order to enable the
Fund to participate in these economies of scale. The Board considered economies
of scale to the extent applicable to the Fund's closed-end structure and
determined that no changes were currently necessary.

Conclusion

After the independent directors deliberated in executive session, the entire
Board, including all of the independent directors, approved the renewal of the
existing FAM Investment Advisory Agreement, concluding that the management fee
rate was reasonable in relation to the services provided and that a contract
renewal was in the best interests of the shareholders.


24      BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006


Disclosure of New Investment Advisory Agreement

New BlackRock Investment Advisory Agreement -- Matters Considered by the Board

In connection with the combination of Merrill Lynch's investment advisory
business, including Fund Asset Management, L.P. (the "Previous Investment
Adviser"), with that of BlackRock, Inc. ("BlackRock") to create a new
independent company ("New BlackRock") (the "Transaction"), the Board of
Directors considered and approved a new investment advisory agreement (the
"BlackRock Investment Advisory Agreement") between the Fund and BlackRock
Advisors, LLC ("BlackRock Advisors"). The Fund's shareholders subsequently
approved the BlackRock Investment Advisory Agreement and it became effective on
September 29, 2006, replacing the Fund's investment advisory agreement with the
Previous Investment Adviser (the "Previous Investment Advisory Agreement").

The Board discussed the BlackRock Investment Advisory Agreement at telephonic
and in-person meetings held during April and May 2006. The Board, including the
independent directors, approved the BlackRock Investment Advisory Agreement at
an in-person meeting held on May 12, 2006.

To assist the Board in its consideration of the BlackRock Investment Advisory
Agreement, BlackRock provided materials and information about BlackRock,
including its financial condition and asset management capabilities and
organization, and Merrill Lynch provided materials and information about the
Transaction. The independent directors, through their independent legal counsel,
also requested and received additional information from Merrill Lynch and
BlackRock in connection with their consideration of the BlackRock Investment
Advisory Agreement. The additional information was provided in advance of the
May 12, 2006 meetings. In addition, the independent directors consulted with
their counsel and Fund counsel on numerous occasions, discussing, among other
things, the legal standards and certain other considerations relevant to the
directors' deliberations.

At the Board meetings, the directors discussed with Merrill Lynch management and
certain BlackRock representatives the Transaction, its strategic rationale and
BlackRock's general plans and intentions regarding the Fund. At these Board
meetings, representatives of Merrill Lynch and BlackRock made presentations to
and responded to questions from the Board. The directors also inquired about the
plans for and anticipated roles and responsibilities of certain employees and
officers of the Previous Investment Adviser, and of its affiliates, to be
transferred to BlackRock in connection with the Transaction. The independent
directors also conferred separately and with their counsel about the Transaction
and other matters related to the Transaction on a number of occasions, including
in connection with the April and May 2006 meetings. After the presentations and
after reviewing the written materials provided, the independent directors met in
executive sessions with their counsel to consider the BlackRock Investment
Advisory Agreement.

In connection with the Board's review of the BlackRock Investment Advisory
Agreement, Merrill Lynch and/or BlackRock advised the directors about a variety
of matters. The advice included the following, among other matters:

o     that there was not expected to be any diminution in the nature, quality
      and extent of services provided to the Fund or its shareholders by
      BlackRock Advisors, including compliance services;

o     that operation of New BlackRock as an independent investment management
      firm would enhance its ability to attract and retain talented
      professionals;

o     that the Fund was expected to benefit from having access to BlackRock's
      state of the art technology and risk management analytic tools, including
      investment tools, provided under the BlackRock Solutions(R) brand name;

o     that BlackRock had no present intention to alter any applicable expense
      waivers or reimbursements that were currently in effect and, while it
      reserved the right to do so in the future, it would seek Board approval
      before making any changes;

o     that in connection with the Transaction, Merrill Lynch and BlackRock had
      agreed to conduct, and use reasonable best efforts to cause their
      respective affiliates to conduct, their respective businesses in
      compliance with the conditions of Section 15(f) of the Investment Company
      Act of 1940 (the "1940 Act") in relation to any public funds advised by
      BlackRock or the Previous Investment Adviser (or affiliates),
      respectively; and

o     that Merrill Lynch and BlackRock would derive benefits from the
      Transaction and that, as a result, they had a financial interest in the
      matters being considered that was different from that of Fund
      shareholders.

The directors considered the information provided by Merrill Lynch and BlackRock
above, and, among other factors, the following:


        BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006              25


Disclosure of New Investment Advisory Agreement (continued)

o     the potential benefits to the Fund's shareholders from being part of a
      combined fund family with BlackRock-sponsored funds, including possible
      economies of scale and access to investment opportunities;

o     the reputation, financial strength and resources of BlackRock and its
      investment advisory subsidiaries and the anticipated financial strength
      and resources of New BlackRock;

o     the compliance policies and procedures of BlackRock Advisors;

o     the terms and conditions of the BlackRock Investment Advisory Agreement,
      including the fact that the Fund's schedule of total advisory fees would
      not increase under the BlackRock Investment Advisory Agreement, but would
      remain the same;

o     that in May 2005, the Board had performed a full annual review of the
      Previous Investment Advisory Agreement, as required by the 1940 Act, and
      had determined that the Previous Investment Adviser had the capabilities,
      resources and personnel necessary to provide the advisory and
      administrative services that were then being provided to the Fund; and
      that the advisory and/or management fees paid by the Fund, taking into
      account any applicable agreed-upon fee waivers and breakpoints, had
      represented reasonable compensation to the Previous Investment Adviser in
      light of the services provided, the costs to the Previous Investment
      Adviser of providing those services, economies of scale, the fees and
      other expenses paid by similar funds (including information provided by
      Lipper Inc. ["Lipper"]), and such other matters as the directors had
      considered relevant in the exercise of their reasonable judgment; and

o     that Merrill Lynch had agreed to pay all expenses of the Fund in
      connection with the consideration by the Board of the BlackRock Investment
      Advisory Agreement and related agreements and all costs of shareholder
      approval of the BlackRock Investment Advisory Agreement and as a result
      the Fund would bear no costs in obtaining shareholder approval of the
      BlackRock Investment Advisory Agreement.

Certain of these considerations are discussed in more detail below.

In its review of the BlackRock Investment Advisory Agreement, the Board assessed
the nature, quality and scope of the services to be provided to the Fund by the
personnel of BlackRock Advisors and its affiliates, including administrative
services, shareholder services, oversight of fund accounting and assistance in
meeting legal and regulatory requirements. In its review of the BlackRock
Investment Advisory Agreement, the Board also considered a range of information
in connection with its oversight of the services to be provided by BlackRock
Advisors and its affiliates. Among the matters considered were: (a) fees (in
addition to management fees) to be paid to BlackRock Advisors and its affiliates
by the Fund; (b) Fund operating expenses paid to third parties; (c) the
resources devoted to and compliance reports relating to the Fund's investment
objective, policies and restrictions, and its compliance with its Code of Ethics
and BlackRock Advisors' compliance policies and procedures; and (d) the nature,
cost and character of non-investment management services to be provided by
BlackRock Advisors and its affiliates.

In the period prior to the Board meeting to consider renewal of the Previous
Investment Advisory Agreement, the Board had requested and received materials
specifically relating to the Previous Investment Advisory Agreement. These
materials included (a) information compiled by Lipper on the fees and expenses
and the investment performance of the Fund as compared to a comparable group of
funds as classified by Lipper; (b) information comparing the Fund's market price
with its net asset value per share; (c) a discussion by the Fund's portfolio
management team on investment strategies used by the Fund during its most recent
fiscal year; (d) information on the profitability to the Previous Investment
Adviser of the Previous Investment Advisory Agreement and other payments
received by the Previous Investment Adviser and its affiliates from the Fund;
and (e) information provided by the Previous Investment Adviser concerning
services related to the valuation and pricing of Fund portfolio holdings, the
Fund's portfolio turnover statistics, and direct and indirect benefits to the
Previous Investment Adviser and its affiliates from their relationship with the
Fund.

In their deliberations, the directors considered information received in
connection with their most recent approval of the continuance of the Previous
Investment Advisory Agreement, in addition to information provided by BlackRock
and BlackRock Advisors in connection with their evaluation of the terms and
conditions of the BlackRock Investment Advisory Agreement. The directors did not
identify any particular information that was all-important or controlling, and
each director attributed different weights to the various factors. The
directors, including a majority of the independent directors, concluded that the
terms of the BlackRock Investment Advisory Agreement are appropriate, that the
fees to be paid are


26      BLACKROCK MUNIVEST FUND II, INC.        OCTOBER 31, 2006


reasonable in light of the services to be provided to the Fund, and that the
BlackRock Investment Advisory Agreement should be approved and recommended to
Fund shareholders.

Nature, Quality and Extent of Services Provided -- The Board reviewed the
nature, quality and scope of services provided by the Previous Investment
Adviser, including the investment advisory services and the resulting
performance of the Fund, as well as the nature, quality and extent of services
expected to be provided by BlackRock Advisors. The Board focused primarily on
the Previous Investment Adviser's investment advisory services and the Fund's
investment performance, but also considered certain areas in which both the
Previous Investment Adviser and the Fund received services as part of the
Merrill Lynch complex. The Board compared the Fund's performance -- both
including and excluding the effects of fees and expenses -- to the performance
of a comparable group of funds, and the performance of a relevant index or
combination of indexes. While the Board reviews performance data at least
quarterly, consistent with the Previous Investment Adviser's investment goals,
the Board attaches more importance to performance over relatively long periods
of time, typically three to five years.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the BlackRock Investment Advisory Agreement, the
directors considered, among other things, the expected impact of the Transaction
on the operations, facilities, organization and personnel of BlackRock Advisors
and how it would affect the Fund; the ability of BlackRock Advisors to perform
its duties after the Transaction; and any anticipated changes to the investment
and other practices of the Fund.

The Board was given information with respect to the potential benefits to the
Fund and its shareholders from having access to BlackRock's state of the art
technology and risk management analytic tools, including the investment tools
provided under the BlackRock Solutions brand name.

The Board was advised that, as a result of Merrill Lynch's equity interest in
BlackRock after the Transaction, the Fund would continue to be subject to
restrictions concerning certain transactions involving Merrill Lynch affiliates
(for example, transactions with a Merrill Lynch broker-dealer acting as
principal) absent revised or new regulatory relief. The directors were advised
that a revision of existing regulatory relief with respect to these restrictions
was being sought from the Securities and Exchange Commission and were advised of
the possibility of the receipt of such revised regulatory relief.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, the directors
determined that the nature and quality of services to be provided to the Fund
under the BlackRock Investment Advisory Agreement were expected to be as good as
or better than that provided under the Previous Investment Advisory Agreement.
The directors were advised that BlackRock Advisors did not plan to change the
Fund's portfolio management team upon the closing of the transaction. It was
noted, however, that other changes in personnel were expected to follow the
Transaction and the combination of the operations of the Previous Investment
Adviser and its affiliates with those of BlackRock. The directors noted that if
current portfolio managers or other personnel were to cease to be available
prior to the closing of the Transaction, the Board would consider all available
options, including seeking the investment advisory or other services of
BlackRock affiliates. Accordingly, the Board concluded that, overall, the Board
was satisfied at the present time with assurances from BlackRock and BlackRock
Advisors as to the expected nature, quality and extent of the services to be
provided to the Fund under the BlackRock Investment Advisory Agreement.

Costs of Services Provided and Profitability -- It was noted that, in
conjunction with their recent review of the Previous Investment Advisory
Agreement, the directors had received, among other things, a report from Lipper
comparing the Fund's fees and expenses to those of a peer group selected by
Lipper, and information as to the fees charged by the Previous Investment
Adviser or its affiliates to other registered investment company clients for
investment management services. The Board reviewed the Fund's contractual
management fee rate and actual management fee rate as a percentage of total
assets at common asset levels -- the actual rate includes advisory fees and the
effects of any fee waivers -- compared to the other funds in its Lipper
category. The Board also compared the Fund's total expenses to those of other
comparable funds. The information showed that the Fund had fees and expenses
within the range of fees and expenses of comparable funds. The Board considered
the services to be provided by and the fees to be charged by BlackRock Advisors
to other funds with similar investment mandates and noted that the fees charged
by BlackRock Advisors in those cases, including fee waivers and expense
reimbursements, were generally comparable to those being charged to the Fund.
The Board concluded that the Fund's management fee rate and overall expense
ratio were reasonable compared to those of other comparable funds.

Disclosure of New Investment Advisory Agreement (concluded)

In evaluating the costs of the services to be provided by BlackRock Advisors
under the BlackRock Investment Advisory Agreement, the Board considered, among
other things, whether advisory fees or other expenses would change as a result
of the Transaction. Based on their review of the materials provided and the fact
that the BlackRock Investment Advisory Agreement is substantially similar to the
Previous Investment Advisory Agreement in all material respects, including the
rate of compensation, the Board determined that the Transaction should not
increase the total fees payable, including any fee waivers and expense
reimbursements, for advisory and administrative services. The Board noted that
it was not possible to predict how the Transaction would affect BlackRock
Advisors' profitability from its relationship with the Fund.

The Board discussed with BlackRock Advisors its general methodology to be used
in determining New BlackRock's profitability with respect to its relationship
with the Fund. The directors noted that they expect to receive profitability
information from BlackRock Advisors on at least an annual basis and thus be in a
position to evaluate whether any adjustments in Fund fees and/or fee breakpoints
would be appropriate.

Fees and Economies of Scale -- The Board considered the extent to which
economies of scale might be realized as the assets of the Fund increase and
whether there should be changes in the management fee rate or structure in order
to enable the Fund to participate in these economies of scale. The Board
determined that changes were not currently necessary.

In reviewing the Transaction, the directors considered, among other things,
whether advisory fees or other expenses would change as a result of the
Transaction. Based on the fact that the BlackRock Investment Advisory Agreement
is substantially similar to the Previous Investment Advisory Agreement in all
material respects, including the rate of compensation, the Board determined that
as a result of the Transaction, the Fund's total advisory fees would be no
higher than the fees under the Previous Investment Advisory Agreement. The
directors noted that in conjunction with their most recent deliberations
concerning the Previous Investment Advisory Agreement, they had determined that
the total fees for advisory and administrative services for the Fund were
reasonable in light of the services provided. It was noted that in conjunction
with the most recent review of the Previous Investment Advisory Agreement, the
Board had received, among other things, a report from Lipper comparing the
Fund's fees, expenses and performance to those of a peer group selected by
Lipper, and information as to the fees charged by the Previous Investment
Adviser to other registered investment company clients for investment management
services. The Board concluded that because the rates for advisory fees for the
Fund would be no higher than the fee rates in effect at the time, the proposed
management fee structure, including any fee waivers, was reasonable in relation
to the services provided and that no changes were currently necessary.

Fall-Out Benefits -- In evaluating the fall-out benefits to be received by
BlackRock Advisors under the BlackRock Investment Advisory Agreement, the Board
considered whether BlackRock Advisors would experience such benefits to the same
extent that the Previous Investment Adviser was experiencing such benefits under
the Previous Investment Advisory Agreement. Based on their review of the
materials provided, including materials received in connection with their most
recent approval of the continuance of the Previous Investment Advisory
Agreement, and their discussions with management of the Previous Investment
Adviser and BlackRock, the directors determined that BlackRock Advisors'
fall-out benefits could include increased ability for BlackRock to distribute
shares of its funds and other investment products. The directors noted that any
fall-out benefits were difficult to quantify with certainty at this time, and
indicated that they would continue to evaluate them going forward.

Investment Performance -- The Board considered investment performance for the
Fund. The Board compared the Fund's performance -- both including and excluding
the effects of fees and expenses -- to the performance of a comparable group of
funds, and the performance of a relevant index or combination of indexes. The
comparative information received from Lipper showed Fund performance at various
levels within the range of performance of comparable funds over different time
periods. While the Board reviews performance data at least quarterly, consistent
with the Previous Investment Adviser's investment goals, the Board attaches more
importance over relatively long periods of time, typically three to five years.
The directors believed the Fund's performance was satisfactory. Also, the Board
took into account the investment performance of funds advised by BlackRock
Advisors. The Board considered comparative information from Lipper which showed
that the performance of the funds advised by BlackRock Advisors was within the
range of performance of comparable funds over different time periods. The Board
noted BlackRock's considerable investment management experience and
capabilities, but was unable to predict what effect, if any, consummation of the
Transaction would have on the future performance of the Fund.

Conclusion -- After the independent directors of the Fund deliberated in
executive session, the entire Board, including the independent directors,
approved the BlackRock Investment Advisory Agreement, concluding that the
management fee rate was reasonable in relation to the services provided and that
the BlackRock Investment Advisory Agreement was in the best interests of the
shareholders. In approving the BlackRock Investment Advisory Agreement, the
Board noted that it anticipated reviewing the continuance of the agreement in
advance of the expiration of the initial two-year period.

New BlackRock Sub-Advisory Agreement -- Matters Considered by the Board

At an in-person meeting held on August 14-16, 2006, the Board of Directors,
including the independent directors, discussed and approved the sub-advisory
agreement (the "BlackRock Sub-Advisory Agreement") between BlackRock Advisors
and its affiliate, BlackRock Investment Management, LLC (the "Sub-Adviser"). The
BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at the
same time the BlackRock Investment Advisory Agreement became effective.

Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a
monthly fee from BlackRock Advisors equal to 59% of the advisory fee received by
BlackRock Advisors from the Fund. BlackRock Advisors pays the Sub-Adviser out of
its own resources, and there is no increase in the Fund expenses as a result of
the BlackRock Sub-Advisory Agreement.

In approving the BlackRock Sub-Advisory Agreement at the August in-person
meeting, the Board reviewed its considerations in connection with its approval
of the BlackRock Investment Advisory Agreement in May 2006. The Board relied on
the same information and considered the same factors as those discussed above in
connection with the approval of the BlackRock Investment Advisory Agreement. In
reviewing the sub-advisory fee rate provided in the BlackRock Sub-Advisory
Agreement, the Board noted the fact that both BlackRock Advisors and the
Sub-Adviser have significant responsibilities under their respective advisory
agreements. BlackRock Advisors remains responsible for oversight of the Fund's
operations and administration, and the Sub-Adviser provides advisory services to
the Fund and is responsible for the day-to-day management of the Fund's
portfolio under the BlackRock Sub-Advisory Agreement. The Board also took into
account the fact that there is no increase in total advisory fees paid by the
Fund as a result of the BlackRock Sub-Advisory Agreement. Under all of the
circumstances, the Board concluded that it was a reasonable allocation of fees
for the Sub-Adviser to receive 59% of the advisory fee paid by the Fund to
BlackRock Advisors.

After the Fund's independent directors deliberated in executive session, the
entire Board, including the independent directors, approved the BlackRock
Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in
relation to the services provided and that the BlackRock Sub-Advisory Agreement
was in the best interests of shareholders.

BlackRock 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

         The Committee is informed of each service approved subject to general
         pre-approval at the next regularly scheduled in-person board meeting.

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

         Proxy Voting Policies and Procedures

         Each Fund's Board of Directors has delegated to the Manager authority
         to vote all proxies relating to the Fund's portfolio securities. The
         Manager has adopted policies and procedures (the "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
         Manager'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 Manager 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
         Manager considers the interests of its clients, including each Fund,
         and not the interests of the Manager, when voting proxies and that real
         (or perceived) material conflicts that may arise between the Manager's
         interest and those of the Manager's clients are properly addressed and
         resolved.

         In order to implement the Proxy Voting Procedures, the Manager has
         formed a Proxy Voting Committee (the "Committee"). The Committee, which
         is a subcommittee of the Manager's Equity Investment Policy Oversight
         Committee ("EIPOC"), is comprised of a senior member of the Manager's
         equity management group who is also a member of EIPOC, one or more
         other senior investment professionals appointed by EIPOC, portfolio
         managers and investment analysts appointed by EIPOC and any other
         personnel EIPOC deems appropriate. The Committee will also include two
         non-voting representatives from the Manager's Legal Department
         appointed by the Manager's General Counsel. The Committee's membership
         shall be limited to full-time employees of the Manager. No person with
         any investment banking, trading, retail brokerage or research
         responsibilities for the Manager'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 Manager 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 Manager 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 Manager 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 Manager
         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 Manager 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 Manager will
         generally seek to vote proxies over which the Manager exercises voting
         authority in a uniform manner for all the Manager'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 Manager 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 Manager by ISS include in-depth research,
         voting recommendations (although the Manager 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 Manager's Proxy Voting Procedures also address special
         circumstances that can arise in connection with proxy voting. For
         instance, under the Proxy Voting Procedures, the Manager 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 Manager 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 Manager may be required to vote proxies in
         respect of an issuer where an affiliate of the Manager (each, an
         "Affiliate"), or a money management or other client of the Manager,
         including investment companies for which the Manager provides
         investment advisory, administrative and/or other services (each, a
         "Client"), is involved. The Proxy Voting Procedures and the Manager'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 Manager'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 Committee may pass the voting power to a subcommittee,
         appointed by EIPOC (with advice from the Secretary of the Committee),
         consisting solely of Committee members selected by EIPOC. EIPOC 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 Manager'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
         Manager'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
         Manager's normal voting guidelines or, on matters where the Manager'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 Manager 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
         Manager's fiduciary duties.

         In addition to the general principles outlined above, the Manager 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 Manager 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 Manager 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 number of other
         directorships, 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, which 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.

         in the Fund's portfolio during the most recent 12 month period ended
         October 31 is available without charge (1) at www.blackrock.com and (2)

         (iv) Potential Material Conflicts of Interest

         BlackRock has built a professional working environment, firm-wide
         compliance culture and compliance procedures and systems designed to
         protect against potential incentives that may favor one account over
         another. BlackRock has adopted policies and procedures that address the
         allocation of investment opportunities, execution of portfolio
         transactions, personal trading by employees and other potential
         conflicts of interest that are designed to ensure that all client
         accounts are treated equitably over time. Nevertheless, BlackRock
         furnishes investment management and advisory services to numerous
         clients in addition to the Fund, and BlackRock may, consistent with
         applicable law, make investment recommendations to other clients or
         accounts (including accounts which are hedge funds or have performance
         or higher fees paid to BlackRock, or in which portfolio managers have a
         personal interest in the receipt of such fees), which may be the same
         as or different from those made to the Fund. In addition, BlackRock,
         its affiliates and any officer, director, stockholder or employee may
         or may not have an interest in the securities whose purchase and sale
         BlackRock recommends to the Fund. BlackRock, or any of its affiliates,
         or any officer, director, stockholder, employee or any member of their
         families may take different actions than those recommended to the Fund
         by BlackRock with respect to the same securities. Moreover, BlackRock
         may refrain from rendering any advice or services concerning securities
         of companies of which any of BlackRock's (or its affiliates') officers,
         directors or employees are directors or officers, or companies as to
         which BlackRock or any of its affiliates or the officers, directors and
         employees of any of them has any substantial economic interest or
         possesses material non-public information. Each portfolio manager also
         may manage accounts whose investment strategies may at times be opposed
         to the strategy utilized for the Fund. In this connection, it should be
         noted that certain portfolio managers currently manage certain accounts
         that are subject to performance fees. In addition, certain portfolio
         managers assist in managing certain hedge funds and may be entitled to
         receive a portion of any incentive fees earned on such funds and a
         portion of such incentive fees may be voluntarily or involuntarily
         deferred. Additional portfolio managers may in the future manage other
         such accounts or funds and may be entitled to receive incentive fees.

         As a fiduciary, BlackRock owes a duty of loyalty to its clients and
         must treat each client fairly. When BlackRock purchases or sells
         securities for more than one account, the trades must be allocated in a
         manner consistent with its fiduciary duties. BlackRock attempts to
         allocate investments in a fair and equitable manner among client
         accounts, with no account receiving preferential treatment. To this
         end, BlackRock has adopted a policy that is intended to ensure that
         investment opportunities are allocated fairly and equitably among
         client accounts over time. This policy also seeks to achieve reasonable
         efficiency in client transactions and provide BlackRock with sufficient
         flexibility to allocate investments in a manner that is consistent with
         the particular investment discipline and client base.

         (a)(3) As of October 31, 2006:

      Portfolio Manager Compensation

      The portfolio manager compensation program of BlackRock and its
affiliates, including the Investment Adviser, is critical to BlackRock's ability
to attract and retain the most talented asset management professionals. This
program ensures that compensation is aligned with maximizing investment returns
and it provides a competitive pay opportunity for competitive performance.



      Compensation Program

      The elements of total compensation for certain BlackRock and its
affiliates portfolio managers are a fixed base salary, annual performance-based
cash and stock compensation (cash and stock bonus) and other benefits. BlackRock
has balanced these components of pay to provide portfolio managers with a
powerful incentive to achieve consistently superior investment performance. By
design, portfolio manager compensation levels fluctuate -- both up and down --
with the relative investment performance of the portfolios that they manage.

      Base Salary

      Under the BlackRock approach, like that of many asset management firms,
base salaries represent a relatively small portion of a portfolio manager's
total compensation. This approach serves to enhance the motivational value of
the performance-based (and therefore variable) compensation elements of the
compensation program.

      Performance-Based Compensation

      BlackRock believes that the best interests of investors are served by
recruiting and retaining exceptional asset management talent and managing their
compensation within a consistent and disciplined framework that emphasizes pay
for performance in the context of an intensely competitive market for talent. To
that end, certain BlackRock and its affiliates portfolio manager incentive
compensation is based on a formulaic compensation program.

      BlackRock's formulaic portfolio manager compensation program includes:
investment performance relative to a subset of general closed-end, leveraged,
municipal debt funds over 1-, 3- and 5-year performance periods and a measure of
operational efficiency. Portfolio managers are compensated based on the pre-tax
performance of the products they manage. If a portfolio manager's tenure is less
than 5-years, performance periods will reflect time in position. Portfolio
managers are compensated based on the products they manage. A discretionary
element of portfolio manager compensation may include consideration of:
financial results, expense control, profit margins, strategic planning and
implementation, quality of client service, market share, corporate reputation,
capital allocation, compliance and risk control, leadership, workforce
diversity, supervision, technology and innovation. All factors are considered
collectively by BlackRock management.

      Cash Bonus

      Performance-based compensation is distributed to portfolio managers in a
combination of cash and stock. Typically, the cash bonus, when combined with
base salary, represents more than 60% of total compensation for portfolio
managers.

      Stock Bonus

      A portion of the dollar value of the total annual performance-based bonus
is paid in restricted shares of BlackRock stock. Paying a portion of annual
bonuses in stock puts compensation earned by a portfolio manager for a given
year "at risk" based on the Company's ability to sustain and improve its
performance over future periods.

      The ultimate value of stock bonuses is dependent on future BlackRock stock
price performance. As such, the stock bonus aligns each portfolio manager's
financial interests with those of BlackRock shareholders and encourages a
balance between short-term goals and long-term strategic objectives. Management



strongly believes that providing a significant portion of competitive
performance-based compensation in stock is in the best interests of investors
and shareholders. This approach ensures that portfolio managers participate as
shareholders in both the "downside risk" and "upside opportunity" of the
Company's performance. Portfolio managers therefore have a direct incentive to
protect BlackRock's reputation for integrity.

      Other Compensation Programs

      Portfolio managers who meet relative investment performance and financial
management objectives during a performance year are eligible to participate in a
deferred cash program. Awards under this program are in the form of deferred
cash that may be benchmarked to a menu of certain BlackRock mutual funds
(including their own funds) during a five-year vesting period. The deferred cash
program aligns the interests of participating portfolio managers with the
investment results of BlackRock products and promotes continuity of successful
portfolio management teams.

      Other Benefits

      Portfolio managers are also eligible to participate in broad-based plans
offered generally to BlackRock employees, including broad-based retirement,
401(k), health, and other employee benefit plans.

      (a)(4) Beneficial Ownership of Securities. As of October 31, 2006, neither
             of Messrs. Jaeckel and O'Connor beneficially owns stock issued by
             the Fund. Mr. Stuebe beneficially owns stock issued by the Fund in
             the range of over $100,000.

Item 9 - Purchases of Equity Securities by Closed-End Management Investment
         Company and Affiliated Purchasers - Not Applicable

Item 10 - Submission of Matters to a Vote of Security Holders - Not Applicable

Item 11 - Controls and Procedures

11(a) - The Registrant's principal executive and principal financial officers
        have evaluated the Registrant's disclosure controls and procedures,
        including internal control over financial reporting, within 90 days of
        this filing. Such principal officers have concluded that the
        Registrant's disclosure controls and procedures were effective in design
        and operation to reasonably ensure that information required to be
        disclosed by the Registrant in this Form N-CSR was recorded, processed,
        summarized, and reported within the required time periods, and were
        sufficient to form the basis of the certifications required by Rule
        30a-(2) of the Investment Company Act of 1940, as amended. Prior to
        reaching that conclusion, such principal officers had become aware of
        matters relating to the Registrant's participation in certain inverse
        floater structures that necessitated adjustments to financial
        information included in Item 1 of this filing. As a result, management
        of the Registrant has reevaluated certain disclosure controls and
        procedures determined not to be effective, as discussed more fully
        below.

        Management of the Registrant is responsible for establishing and
        maintaining effective internal control over financial reporting. In
        fulfilling this responsibility, estimates and judgments by management
        are required to assess the expected benefits and related costs of
        controls. The Registrant's internal control over financial reporting is
        a process designed to provide reasonable assurance regarding the
        reliability of financial reporting and the preparation of financial



        statements for external purposes in accordance with U.S. generally
        accepted accounting principles. Such internal control includes policies
        and procedures that provide reasonable assurance regarding prevention or
        timely detection of unauthorized acquisition, use or disposition of a
        registrant's assets that could have a material effect on the financial
        statements.

        Because of its inherent limitations, internal control over financial
        reporting may not prevent or detect misstatements. Also, projections of
        any evaluation of effectiveness to future periods are subject to the
        risk that controls may become inadequate because of changes in
        conditions, or that the degree of compliance with the policies or
        procedures may deteriorate.

        A control deficiency exists when the design or operation of a control
        does not allow management or employees, in the normal course of
        performing their assigned functions, to prevent or detect misstatements
        on a timely basis. A significant deficiency is a control deficiency, or
        combination of control deficiencies, that adversely affects the
        Registrant's ability to initiate, authorize, record, process or report
        financial data reliably in accordance with generally accepted accounting
        principles such that there is more than a remote likelihood that a
        misstatement of the Registrant's annual or interim financial statements
        that is more than inconsequential will not be prevented or detected. A
        material weakness is a significant deficiency, or combination of
        significant deficiencies, that results in more than a remote likelihood
        that a material misstatement of the annual or interim financial
        statements will not be prevented or detected.

        Prior to the filing of this Form N-CSR, the Registrant identified the
        following control deficiency, that was determined to be a material
        weakness, as defined above, in the Registrant's internal control over
        financial reporting. The Registrant's controls related to the review and
        analysis of relevant terms and conditions of transfers of certain assets
        pertaining to inverse floater structures were not operating effectively
        to appropriately determine whether the transfers of assets qualified for
        sale accounting under the provisions of Statement of Financial
        Accounting Standards No. 140, "Accounting for Transfers and Servicing of
        Financial Assets and Extinguishments of Liabilities" ("SFAS 140").
        Accordingly, the Registrant's financial statements as of and for the
        period ended October 31, 2006, including prior periods where applicable,
        were adjusted prior to being issued to appropriately reflect transfers
        of such securities as secured borrowings and to report the related
        income and expense. These adjustments had no impact on net assets, net
        asset value per share or total return.

        Management of the Registrant believes that subsequent to the
        adjustments, the Registrant's accounting treatment of such transfers is
        appropriate under SFAS 140. Additionally, management of the Registrant
        is taking such further actions as are necessary to enhance its internal
        control over financial reporting, and in doing so, increase the
        effectiveness of such controls, so that such transfers of assets are
        reviewed and evaluated appropriately under the provisions of SFAS 140.

11(b) - There have been no changes in the Registrant's internal control over
        financial reporting (as defined in Rule 30a-3(d) under the Investment
        Company Act of 1940, as amended) that occurred during the second half of
        the Registrant's fiscal year that have materially affected, or are
        reasonably likely to materially affect, the Registrant's internal
        control over financial reporting. However, as discussed above,
        subsequent to October 31, 2006, the Registrant is further enhancing
        controls related to the application of SFAS 140.
