Past performance is no guarantee of future results. Index performance shown for

Subprime mortgage woes dominated headlines for much of 2007, but intensified in
the summer and fall, spawning a widespread liquidity and credit crisis with
ramifications across global markets. The Federal Reserve Board (the "Fed") and
other countries' central banks stepped in to inject liquidity into the markets
and bolster investor confidence. The Fed cut the federal funds rate by 0.50% in
September and another 0.25% on the final day of the reporting period, bringing
its target rate to 4.50%. In taking action, the central bankers, who had long
deemed themselves inflation fighters, were seeking to stem the fallout from the
credit crunch and forestall a wider economic unraveling. By period-end, the Fed
had cited the risks between slower economic growth and faster inflation as
equally balanced.

Amid the volatility throughout the past year, equity markets have displayed
surprising resilience. Most recently, the credit turmoil dampened corporate
merger-and-acquisition (M&A) activity, a key source of strength for equity
markets. Still, market fundamentals have held firm, dividend payouts and share
buybacks have continued to grow, and valuations remain attractive. These
tailwinds generally have prevailed over the headwinds created by the slowing
U.S. economy, troubled housing market and, recently, a more difficult corporate
earnings backdrop. International markets fared even better than U.S. equities,
benefiting from robust M&A activity and generally stronger economies.

In fixed income markets, mixed economic signals and the credit woes resulted in
a flight to quality. At the height of the uncertainty, investors shunned bonds
associated with the housing and credit markets in favor of higher-quality
Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in
June (its highest level in five years), fell to 4.48% by period-end, while
prices correspondingly rose. The tax-exempt bond market has been challenged by a
combination of record-setting supply year-to-date, economic uncertainty and
concerns around the credit worthiness of bond insurers. This has brought
municipal bond prices to relatively attractive levels and, as such, demand
generally has remained firm.

As you navigate market volatility, we encourage you to review your investment
goals with your financial professional and to make portfolio changes, as needed.

Notes to Financial Statements

1. Significant Accounting Policies:

BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc.,
BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II,
Inc. (the "Funds" or individually as the "Fund"), are registered under the
Investment Company Act of 1940, as amended, as non-diversified, closed-end
management investment companies. The Funds' 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 Funds determine and make available for publication the net
asset value of their Common Stock on a daily basis. The Funds' Common Stock
shares are listed on the New York Stock Exchange under the symbol MYD for
BlackRock MuniYield Fund, Inc., MYI for BlackRock MuniYield Insured Fund, Inc.,
MQY for BlackRock MuniYield Quality Fund, Inc. and MQT for BlackRock MuniYield
Quality Fund II, Inc. The following is a summary of significant accounting
policies followed by the Funds.

(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 each of the Funds under the general
direction of the respective Board of Directors. Such valuations and procedures
are reviewed periodically by the Boards of Directors of the Funds. Financial
futures contracts and options thereon, which are traded on exchanges, are valued
at their closing prices as of the close of such exchanges. Effective September
4, 2007, exchange-traded options are valued at the mean between the last bid and
ask prices at the close of the options market in which the options trade and
previously were valued at the last sales price as of the close of options
trading on the applicable exchanges. 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 Funds' pricing service. 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 each Fund's Board of
Directors.

(b) Derivative financial instruments -- Each 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
due to an unfavorable change in the price of the underlying security or if the
counterparty does not perform under the contract. The counterparty for certain
instruments may pledge cash or securities as collateral.

o     Financial futures contracts -- Each 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 -- Each Fund may purchase and write call and put options. When the
      Fund writes an option, an amount equal to the premium received by the Fund
      is reflected as an asset and an equivalent liability. The amount of the
      liability is subsequently marked-to-market 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 -- Each 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 -- Each 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 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 Statements
      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

Notes to Financial Statements (continued)

      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 -- Certain Funds invest 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 a 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. Each Fund's transfers of the municipal
securities to a TOB do not qualify for sale treatment under Statement of
Financial Accounting Standards No. 140 ("FAS 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 Funds' schedules
of investments and the proceeds from the transactions are reported as liability
for trust certificates. 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
Funds 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 a 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 Funds include the right of the Funds (1) to cause
the holders of a proportional share of 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 Funds. At October 31, 2007, the
aggregate value of the underlying municipal securities transferred to TOBs and
the liability for trust certificates were:

--------------------------------------------------------------------------------
                                                                     Underlying
                                                                      Municipal
                                  Liability         Range of            Bonds
                                  for Trust         Interest         Transferred
                                Certificates         Rates             to TOBs
--------------------------------------------------------------------------------
BlackRock MuniYield
  Fund, Inc. ...............    $ 36,112,500    3.693% -- 3.72%     $ 77,237,013

BlackRock MuniYield
  Insured Fund, Inc. .......    $170,637,500    3.525% -- 3.758%    $355,738,664

BlackRock MuniYield
  Quality Fund, Inc. .......    $ 76,685,000    3.686% -- 3.758%    $161,925,912

BlackRock MuniYield
  Quality Fund II, Inc. ....    $ 47,725,000    3.701% -- 3.758%    $ 98,871,863
--------------------------------------------------------------------------------

Financial transactions executed through TOBs generally will underperform 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, a Fund's
investments in TOB Residuals likely will adversely affect a 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
Funds' net asset values per share.

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

(d) Income taxes -- It is each 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 Funds amortize 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 certain
Funds' Preferred Stock were charged to capital at the time of issuance of the
shares. Any adjustments to estimates of offering costs were recorded back to
capital.

(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
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on each of the Fund's financial statements, if any, is currently being assessed.

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. At this time, management is evaluating the implications of FAS 157
and its impact on each of the Fund's financial statements, if any, has not been
determined.

Notes to Financial Statements (continued)

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on each of the Fund's financial
statements, if any, has not been determined.

(i) Reclassifications -- U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, for BlackRock
MuniYield Insured Fund, Inc., during the current year, $5,774,510 has been
reclassified between accumulated net realized capital losses and paid-in capital
in excess of par as a result of permanent differences attributable to the
difference between the book and tax treatment of residual interests in tender
option bonds.

Accordingly, for BlackRock MuniYield Quality Fund, Inc., during the current
year, $4,779 has been reclassified between undistributed net investment income
and accumulated net realized capital losses as a result of permanent differences
attributable to amortization methods on fixed income securities. These
reclassifications have no effect on net assets or net asset values per share.

2. Investment Advisory Agreement and Transactions with Affiliates:

Each Fund has entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC
Financial Services Group, Inc. are the principal owners of BlackRock, Inc.

The Manager is responsible for the management of each of the Fund's portfolios
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of each Fund. For such services, each 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 has
agreed to reimburse its management fee by the amount of management fees each
Fund pays to the Manager indirectly through its investment in Merrill Lynch
Institutional Tax-Exempt Fund. The reimbursements for the year ended October 31,
2007 were as follows:

--------------------------------------------------------------------------------
                                                                  Reimbursement
                                                                  by the Manager

--------------------------------------------------------------------------------

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 monthly fee at an
annual rate that is a percentage of the management fee paid by each Fund to the
Manager.

The Funds reimbursed the Manager for certain accounting services. The
reimbursements for the year ended October 31, 2007 were as follows:

--------------------------------------------------------------------------------
                                                                  Reimbursement

6. Restatement Information:

Subsequent to the initial issuance of BlackRock MuniYield Insured Fund, Inc.'s
October 31, 2006 financial statements, the Fund determined that the criteria for
sale accounting in FAS 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. As a result, certain financial highlights for
each of the three years in the period ended October 31, 2005 have been restated
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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Boards of Directors of BlackRock MuniYield Fund, Inc.,
BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc.
and BlackRock MuniYield Quality Fund II, Inc.:

We have audited each of the accompanying statements of net assets, including the
schedules of investments, of BlackRock MuniYield Fund, Inc., BlackRock MuniYield
Quality Fund, Inc., and BlackRock MuniYield Quality Fund II, Inc. as of October
31, 2007, and the related statements 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 for each of the respective funds. We have also audited the
accompanying statement of net assets, including the schedule of investments, of
BlackRock MuniYield Insured Fund, Inc. as of October 31, 2007, and the related
statement of operations for the year then ended, and the statements of changes
in net assets and the financial highlights for each of the two years in the
period then ended. The above-referenced funds are hereinafter referred to
collectively as the "Funds." These financial statements and financial highlights
are the responsibility of the Funds' management. Our responsibility is to
express an opinion on the financial statements and financial highlights of each
of the Funds based on our audits. The financial highlights of BlackRock
MuniYield Insured Fund, Inc. for each of the three years in the period ended
October 31, 2005 (before the restatement described in Note 6) were audited by
other auditors whose report, dated December 9, 2005, expressed a qualified
opinion on those financial highlights because of the errors described in Note 6.

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 Funds
are not required to have, nor were we engaged to perform, audits of their
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 Funds' 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, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of October 31, 2007, 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 of BlackRock
MuniYield Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock
MuniYield Quality Fund II, Inc. referred to above present fairly, in all
material respects, the respective financial positions of each of those funds as
of October 31, 2007, the results of their operations for the year then ended,
the changes in their net assets for each of the two years in the period then
ended, and their 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. Additionally, in our opinion, the financial statements
and financial highlights of BlackRock MuniYield Insured Fund, Inc. as of October
31, 2007 and for each of the two years in the period then ended, present fairly,
in all material respects, its financial position as of October 31, 2007, the
results of its operations for the year then ended, and the changes in its net
assets and the financial highlights for each of the two years in the period then
ended, in conformity with accounting principles generally accepted in the United
States of America.

We also have audited the adjustments, applied by management, to restate certain
financial highlights of BlackRock MuniYield Insured Fund, Inc. (the "Insured
Fund") for each of the three years in the period ended October 31, 2005, to
correct the errors described in Note 6. These adjustments are the responsibility
of the Insured Fund's management. The audit procedures that we performed with
respect to the adjustments included such tests as we considered necessary in the
circumstances and were designed to obtain reasonable assurance about whether the
adjustments are appropriate and have been properly applied, in all material
respects, to the restated information in Insured Fund's financial highlights for
each of the three years in the period ended October 31, 2005. We did not perform
any audit procedures designed to assess whether any additional adjustments or
disclosures to the Insured Fund's financial highlights for each of the three
years in the period ended October 31, 2005 might be necessary in order for such
financial highlights to be presented in conformity with accounting principles
generally accepted in the United States of America. In our opinion, the
adjustments to the financial highlights of the Insured Fund for each of the
three years in the period ended October 31, 2005, for the restatement described
in Note 6 are appropriate and have been properly applied, in all material
respects. However, we were not engaged to audit, review, or apply any procedures
to the Insured Fund's financial highlights for each of the three years in the
period ended October 31, 2005, other than with respect to the adjustments
described in Note 6 and, accordingly, we do not express an opinion or any other
form of assurance on the Insured Fund's financial highlights for each of the
three years in the period ended October 31, 2005.

Important Tax Information

All of the net investment income distributions paid by BlackRock MuniYield Fund,
Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund,
Inc. and BlackRock MuniYield Quality Fund II, Inc. during the taxable year ended
October 31, 2007 qualify as tax-exempt interest dividends for federal income tax
purposes.

The Benefits and Risks of Leveraging

The Funds utilize leverage to seek to enhance the yield and net asset value of
their Common Stock. However, these objectives cannot be achieved in all interest
rate environments. To leverage, each 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 each 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, 2007, BlackRock MuniYield Fund, Inc., BlackRock MuniYield
Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock
MuniYield Quality Fund II, Inc. had leverage amounts, due to Auction Market
Preferred Stock, of 34.58%, 36.71%, 35.52% and 35.14% of total net assets,
respectively, before the deduction of Preferred Stock.

As a part of their investment strategy, the Funds 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 Funds 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 Funds invest
in inverse floaters, the market value of each Fund's portfolio and the net asset
value of each Fund's shares may also be more volatile than if the Funds did not
invest in these securities. To the extent the Funds invest in inverse floaters,
the market value of the Funds' portfolio and net asset value of the Funds'
shares may also be more volatile than if the Funds did not invest in these
securities. (See Note 1(c) to Financial Statements for details of municipal
bonds held in trust.)

Swap Agreements

The Funds 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 each
Fund has entered into a 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.

Automatic Dividend Reinvestment Plan

How the Plan Works -- The Funds offer a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by each Fund are
automatically reinvested in additional shares of Common Stock of each Fund. The
Plan is administered on behalf of the shareholders by The Bank of New York
Mellon for BlackRock MuniYield Fund, Inc. and BlackRock MuniYield Quality Fund
II, Inc. and Computershare Trust Company, N.A. for BlackRock MuniYield Insured
Fund, Inc. and BlackRock MuniYield Quality Fund, Inc. (individually, the "Plan
Agent" or together, the "Plan Agents"). Under the Plan, whenever the Funds
declare a dividend, participants in the Plan will receive the equivalent in
shares of Common Stock of each Fund. The Plan Agents will acquire the shares for
the participant's account either (i) through receipt of additional unissued but
authorized shares of each 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, each 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 Agents will invest the dividend amount in newly issued
shares. If the Funds' net asset value per share is greater than the market price
per share (a condition often referred to as a "market discount"), the Plan
Agents will invest the dividend amount by purchasing on the open market
additional shares. If the Plan Agents are 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 Agents 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 Funds 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 their 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 Funds. 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 each Fund's shares is above the net asset value,
participants in the Plan will receive shares of the Funds 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 each 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 Agents' service fees for handling the reinvestment of
distributions are paid for by the Funds. However, brokerage commissions may be
incurred when the Funds purchase 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 Funds' shares are trading at a
market premium, the Funds issue 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 each 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

As a result, the dividends paid by the Funds for any particular month may be
more or less than the amount of net investment income earned by the Funds during
such month. The Funds' current accumulated but undistributed net investment
income, if any, is disclosed in the Statements of Net Assets, which comprises

This report, including the financial information herein, is transmitted to
shareholders of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured
Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield

performance results shown in this report should not be considered a
representation of future performance. The Funds have leveraged their Common
Stock and intend to remain leveraged by issuing Preferred Stock to provide the

and the risk that fluctuations in the short-term dividend rates of the Preferred
Stock may affect the yield to Common Stock shareholders. Statements and other
information herein are as dated and are subject to change.

            principal financial officer and principal accounting officer, or

Item 3 -    Audit Committee Financial Expert - The registrant's board of
            directors or trustees, as applicable (the "board of directors") has
            determined that (i) the registrant has the following audit committee
            financial experts serving on its audit committee and (ii) each audit
            committee financial expert is independent:
            Joe Grills (term ended effective November 1, 2007)
            Robert S. Salomon, Jr.
            Kent Dixon (term began effective November 1, 2007)
            Frank J. Fabozzi (term began effective November 1, 2007)
            W. Carl Kester (term began effective November 1, 2007)
            James T. Flynn (term began effective November 1, 2007)
            Karen P. Robards (term began effective November 1, 2007)

            The registrant's board of directors has determined that W. Carl
            Kester and Karen P. Robards qualify as financial experts pursuant to
            Item 3(c)(4) of Form N-CSR.

            Prof. Kester has a thorough understanding of generally accepted
            accounting principles, financial statements and internal control
            over financial reporting as well as audit committee functions. Prof.
            Kester has been involved in providing valuation and other financial
            consulting services to corporate clients since 1978. Prof. Kester's
            financial consulting services present a breadth and level of
            complexity of accounting issues that are generally comparable to the
            breadth and complexity of issues that can reasonably be expected to
            be raised by the registrant's financial statements.

            Ms. Robards has a thorough understanding of generally accepted
            accounting principles, financial statements and internal control
            over financial reporting as well as audit committee functions. Ms.
            Robards has been President of Robards & Company, a financial
            advisory firm, since 1987. Ms. Robards was formerly an investment
            banker for more than 10 years where she was responsible for
            evaluating and assessing the performance of companies based on their
            financial results. Ms. Robards has over 30 years of experience
            analyzing financial statements. She also is the member of the Audit
            Committees of one publicly held company and a non-profit
            organization.

            Under applicable securities laws, a person determined to be an audit
            committee financial expert will not be deemed an "expert" for any
            purpose, including without limitation for the purposes of Section 11
            of the Securities Act of 1933, as a result of being designated or
            identified as an audit committee financial expert. The designation
            or identification as an audit committee financial expert does not
            impose on such person any duties, obligations, or liabilities
            greater than the duties, obligations, and liabilities imposed on
            such person as a member of the audit committee and board of
            directors in the absence of such designation or identification.

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

            (e)(2) None of the services described in each of Items 4(b) through
            (d) were approved by the audit committee pursuant to paragraph
            (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

            (f) Not Applicable

            registrant's investment adviser (not including any non-affiliated
            sub-adviser whose role is primarily portfolio management and is
            subcontracted with or overseen by the registrant's investment
            adviser), and any entity controlling, controlled by, or under common



            control with the investment adviser that provides ongoing services
            to the registrant that were not pre-approved pursuant to paragraph
            (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with

                      Proxy Voting Policies and Procedures

      These Proxy Voting Policies and Procedures ("Policy") for BlackRock
Advisors, LLC and its affiliated U.S. registered investment advisers(1)
("BlackRock") reflect our duty as a fiduciary under the Investment Advisers Act
of 1940 (the "Advisers Act") to vote proxies in the best interests of our
clients. BlackRock serves as the investment manager for investment companies,
other commingled investment vehicles and/or separate accounts of institutional
and other clients. The right to vote proxies for securities held in such
accounts belongs to BlackRock's clients. Certain clients of BlackRock have
retained the right to vote such proxies in general or in specific
circumstances.(2) Other clients, however, have delegated to BlackRock the right
to vote proxies for securities held in their accounts as part of BlackRock's
authority to manage, acquire and dispose of account assets.

      When BlackRock votes proxies for a client that has delegated to BlackRock
proxy voting authority, BlackRock acts as the client's agent. Under the Advisers
Act, an investment adviser is a fiduciary that owes each of its clients a duty
of care and loyalty with respect to all services the adviser undertakes on the
client's behalf, including proxy voting. BlackRock is therefore subject to a
fiduciary duty to vote proxies in a manner BlackRock believes is consistent with
the client's best interests,(3) whether or not the client's proxy voting is
subject to the fiduciary standards of the Employee Retirement Income Security
Act of 1974 ("ERISA").(4) When voting proxies for client accounts (including
investment companies), BlackRock's primary objective is to make voting decisions
solely in the best interests of clients and ERISA clients' plan beneficiaries
and participants. In fulfilling its obligations to clients, BlackRock will seek
to act in a manner that it believes is most likely to enhance the economic value
of the underlying securities held in client accounts.(5) It is imperative that
BlackRock considers the interests of its clients, and not the interests of
BlackRock, when voting proxies and that real (or perceived) material conflicts
that may arise between BlackRock's interest and those of BlackRock's clients are
properly addressed and resolved.

----------
(1) The Policy does not apply to BlackRock Asset Management U.K. Limited and
BlackRock Investment Managers International Limited, which are U.S. registered
investment advisers based in the United Kingdom.

(2) In certain situations, a client may direct BlackRock to vote in accordance
with the client's proxy voting policies. In these situations, BlackRock will
seek to comply with such policies to the extent it would not be inconsistent
with other BlackRock legal responsibilities.

(3) Letter from Harvey L. Pitt, Chairman, SEC, to John P.M. Higgins, President,
Ram Trust Services (February 12, 2002) (Section 206 of the Investment Advisers
Act imposes a fiduciary responsibility to vote proxies fairly and in the best
interests of clients); SEC Release No. IA-2106 (February 3, 2003).

(4) DOL Interpretative Bulletin of Sections 402, 403 and 404 of ERISA at 29
C.F.R. 2509.94-2.

(5) Other considerations, such as social, labor, environmental or other
policies, may be of interest to particular clients. While BlackRock is cognizant
of the importance of such considerations, when voting proxies it will generally
take such matters into account only to the extent that they have a direct
bearing on the economic value of the underlying securities. To the extent that a
BlackRock client desires to pursue a particular social, labor, environmental or
other agenda through the proxy votes made for its securities held through
BlackRock as investment adviser, BlackRock encourages the client to consider
retaining direct proxy voting authority or to appoint independently a special
proxy voting fiduciary other than BlackRock.


                                       1


      Advisers Act Rule 206(4)-6 was adopted by the SEC in 2003 and requires,
among other things, that an investment adviser that exercises voting authority
over clients' proxy voting adopt policies and procedures reasonably designed to
ensure that the adviser votes proxies in the best interests of clients,
discloses to its clients information about those policies and procedures and
also discloses to clients how they may obtain information on how the adviser has
voted their proxies.

      In light of such fiduciary duties, the requirements of Rule 206(4)-6, and
given the complexity of the issues that may be raised in connection with proxy
votes, BlackRock has adopted these policies and procedures. BlackRock's Equity
Investment Policy Oversight Committee, or a sub-committee thereof (the
"Committee"), addresses proxy voting issues on behalf of BlackRock and its
clients.(6) The Committee is comprised of senior members of BlackRock's
Portfolio Management Group and advised by BlackRock's Legal and Compliance
Department.

----------
(6) Subject to the Proxy Voting Policies of Merrill Lynch Bank & Trust Company
FSB, the Committee may also function jointly as the Proxy Voting Committee for
Merrill Lynch Bank & Trust Company FSB trust accounts managed by personnel
dually-employed by BlackRock.


                                       2


I. Scope of Committee Responsibilities

      The Committee shall have the responsibility for determining how to address
proxy votes made on behalf of all BlackRock clients, except for clients who have
retained the right to vote their own proxies, either generally or on any
specific matter. In so doing, the Committee shall seek to ensure that proxy
votes are made in the best interests of clients, and that proxy votes are
determined in a manner free from unwarranted or inappropriate influences. The
Committee shall also oversee the overall administration of proxy voting for
BlackRock accounts.(7)

      The Committee shall establish BlackRock's proxy voting guidelines, with
such advice, participation and research as the Committee deems appropriate from
portfolio managers, proxy voting services or other knowledgeable interested
parties. As it is anticipated that there will not necessarily be a "right" way
to vote proxies on any given issue applicable to all facts and circumstances,
the Committee shall also be responsible for determining how the proxy voting
guidelines will be 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 alternative actions. In
so doing, the Committee may determine to vote a particular proxy in a manner
contrary to its generally stated guidelines.

      The Committee may determine that the subject matter of certain proxy
issues are not suitable for general voting guidelines and requires a
case-by-case determination, in which case the Committee may elect not to adopt a
specific voting guideline applicable to such issues. BlackRock believes that
certain proxy voting issues - such as approval of mergers and other significant
corporate transactions - require investment analysis akin to investment
decisions, and are therefore not suitable for general guidelines. The Committee
may elect to adopt a common BlackRock position on certain proxy votes that are
akin to investment decisions, or determine to permit portfolio managers to make
individual decisions on how best to maximize economic value for the accounts for
which they are responsible (similar to normal buy/sell investment decisions made
by such portfolio managers).(8)

      While it is expected that BlackRock, as a fiduciary, will generally seek
to vote proxies over which BlackRock exercises voting authority in a uniform
manner for all BlackRock clients, the Committee, in conjunction with the
portfolio manager of an account, may determine that the specific circumstances
of such account require that such account's proxies be voted differently due to
such account's investment objective or other factors that differentiate it from
other accounts. In addition, on proxy votes that are akin to investment
decisions, BlackRock believes portfolio managers may from time to time

----------
(7) The Committee may delegate day-to-day administrative responsibilities to
other BlackRock personnel and/or outside service providers, as appropriate.

(8) The Committee will normally defer to portfolio managers on proxy votes that
are akin to investment decisions except for proxy votes that involve a material
conflict of interest, in which case it will determine, in its discretion, the
appropriate voting process so as to address such conflict.


                                       3


legitimately reach differing but equally valid views, as fiduciaries for
BlackRock's clients, on how best to maximize economic value in respect of a
particular investment.

      The Committee will also be responsible for ensuring the maintenance of
records of each proxy vote, as required by Advisers Act Rule 204-2.(9) All
records will be maintained in accordance with applicable law. Except as may be
required by applicable legal requirements, or as otherwise set forth herein, the
Committee's determinations and records shall be treated as proprietary,
nonpublic and confidential.

      The Committee shall be assisted by other BlackRock personnel, as may be
appropriate. In particular, the Committee has delegated to the BlackRock
Operations Department responsibility for monitoring corporate actions and
ensuring that proxy votes are submitted in a timely fashion. The Operations
Department shall ensure that proxy voting issues are promptly brought to the
Committee's attention and that the Committee's proxy voting decisions are
appropriately disseminated and implemented.

      To assist BlackRock in voting proxies, the Committee may retain the
services of a firm providing such services. BlackRock has currently retained
Institutional Shareholder Services ("ISS") in that role. 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
BlackRock may include, but are not limited to, in-depth research, voting
recommendations (which the Committee is not obligated to follow), vote
execution, and recordkeeping.

----------
(9) The Committee may delegate the actual maintenance of such records to an
outside service provider. Currently, the Committee has delegated the maintenance
of such records to Institutional Shareholder Services.


                                       4


II. Special Circumstances

      Routine Consents. BlackRock may be asked from time to time to consent to
an amendment to, or grant a waiver under, a loan agreement, partnership
agreement, indenture or other governing document of a specific financial
instrument held by BlackRock clients. BlackRock will generally treat such
requests for consents not as "proxies" subject to these Proxy Voting Policies
and Procedures but as investment matters to be dealt with by the responsible
BlackRock investment professionals would, provided that such consents (i) do not
relate to the election of a board of directors or appointment of auditors of a
public company, and (ii) either (A) would not otherwise materially affect the
structure, management or control of a public company, or (B) relate to a company
in which BlackRock clients hold only interests in bank loans or debt securities
and are consistent with customary standards and practices for such instruments.

      Securities on Loan. Registered investment companies that are advised by
BlackRock as well as certain of our advisory clients may participate in
securities lending programs. Under most securities lending arrangements,
securities on loan may not be voted by the lender (unless the loan is recalled).
BlackRock believes that each client has the right to determine whether
participating in a securities lending program enhances returns, to contract with
the securities lending agent of its choice and to structure a securities lending
program, through its lending agent, that balances any tension between loaning
and voting securities in a matter that satisfies such client. If client has
decided to participate in a securities lending program, BlackRock will therefore
defer to the client's determination and not attempt to seek recalls solely for
the purpose of voting routine proxies as this could impact the returns received
from securities lending and make the client a less desirable lender in a
marketplace. Where a client retains a lending agent that is unaffiliated with
BlackRock, BlackRock will generally not seek to vote proxies relating to
securities on loan because BlackRock does not have a contractual right to recall
such loaned securities for the purpose of voting proxies. Where BlackRock or an
affiliate acts as the lending agent, BlackRock will also generally not seek to
recall loaned securities for proxy voting purposes, unless the portfolio manager
responsible for the account or the Committee determines that voting the proxy is
in the client's best interest and requests that the security be recalled.

      Voting Proxies for Non-US Companies. While the proxy voting process is
well established in the United States, voting proxies of non-US companies
frequently involves logistical issues which can affect BlackRock's ability to
vote such proxies, as well as the desirability of voting such proxies. These
issues include (but are not limited to): (i) untimely notice of shareholder
meetings, (ii) restrictions on a foreigner's ability to exercise votes, (iii)
requirements to vote proxies in person, (iv) "shareblocking" (requirements that
investors who exercise their voting rights surrender the right to dispose of
their holdings for some specified period in proximity to the shareholder
meeting), (v) potential difficulties in translating the proxy, and (vi)
requirements to provide local agents with unrestricted powers of attorney to
facilitate voting instructions.


                                       5


      As a consequence, BlackRock votes proxies of non-US companies only on a
"best-efforts" basis. In addition, the Committee may determine that it is
generally in the best interests of BlackRock clients not to vote proxies of
companies in certain countries if the Committee determines that the costs
(including but not limited to opportunity costs associated with shareblocking
constraints) associated with exercising a vote generally are expected to
outweigh the benefit the client will derive by voting on the issuer's proposal.
If the Committee so determines in the case of a particular country, the
Committee (upon advice from BlackRock portfolio managers) may override such
determination with respect to a particular issuer's shareholder meeting if the
Committee believes the benefits of seeking to exercise a vote at such meeting
outweighs the costs, in which case BlackRock will seek to vote on a best-efforts
basis.

      Securities Sold After Record Date. With respect to votes in connection
with securities held on a particular record date but sold from a client account
prior to the holding of the related meeting, BlackRock may take no action on
proposals to be voted on in such meeting.

      Conflicts of Interest. From time to time, BlackRock may be required to
vote proxies in respect of an issuer that is an affiliate of BlackRock (a
"BlackRock Affiliate"), or a money management or other client of BlackRock (a
"BlackRock Client").(10) In such event, provided that the Committee is aware of
the real or potential conflict, the following procedures apply:

      o     The Committee intends to adhere to the voting guidelines set forth
            herein for all proxy issues including matters involving BlackRock
            Affiliates and BlackRock Clients. 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
            BlackRock's clients; and

      o     if the Committee determines not to retain an independent fiduciary,
            or does not desire to follow the advice of such independent
            fiduciary, the Committee shall determine how to vote the proxy after
            consulting with the BlackRock Legal and Compliance Department and
            concluding that the vote cast is in the client's best interest
            notwithstanding the conflict.

----------
(10) Such issuers may include investment companies for which BlackRock provides
investment advisory, administrative and/or other services.


                                       6


III. Voting Guidelines

      The Committee has determined that it is appropriate and in the best
interests of BlackRock's clients to adopt the following voting guidelines, which
represent the Committee's usual voting position on certain recurring proxy
issues that are not expected to involve unusual circumstances. With respect to
any particular proxy issue, however, the Committee may elect to vote differently
than a voting guideline if the Committee determines that doing so is, in the
Committee's judgment, in the best interest of its clients. The guidelines may be
reviewed at any time upon the request of any Committee member and may be amended
or deleted upon the vote of a majority of voting Committee members present at a
Committee meeting for which there is a quorum.


                                       7


      A. Boards of Directors

      These proposals concern those issues submitted to shareholders relating to
the composition of the Board of Directors of companies 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 Director nominee's history of
representing shareholder interests as a director of other companies, or other
factors to the extent the Committee deems relevant.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------

      elections, except for nominees who

            the previous year, unless the nominee missed the meeting(s) due to
            illness or company business
      o     voted to implement or renew a "dead-hand" poison pill
      o     ignored a shareholder proposal that was approved by either a
            majority of the shares outstanding in any year or by the majority of
            votes cast for two consecutive years
      o     failed to act on takeover offers where the majority of the
            shareholders have tendered their shares

            nominating committees or on a full Board that does not have such
            committees composed exclusively of independent directors
      o     on a case-by-case basis, have served as directors of other companies

A.21  FOR proposals permitting shareholder ability to remove directors directly
--------------------------------------------------------------------------------
A.22  AGAINST proposals to eliminate shareholder ability to remove directors
      directly
--------------------------------------------------------------------------------


                                       9


      B. Auditors

      These proposals concern those issues submitted to shareholders related to
the selection of 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.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
B.1   FOR approval of independent auditors, except for
      o     auditors that have a financial interest in, or material association
            with, the company they are auditing, and are therefore believed by
            the Committee not to be independent
      o     auditors who have rendered an opinion to any company which in the
            Committee's opinion is either not consistent with best accounting
            practices or not indicative of the company's financial situation
      o     on a case-by-case basis, auditors who in the Committee's opinion
            provide a significant amount of non-audit services to the company
--------------------------------------------------------------------------------
B.2   FOR proposals seeking authorization to fix the remuneration of auditors
--------------------------------------------------------------------------------
B.3   FOR approving internal statutory auditors
--------------------------------------------------------------------------------
B.4   FOR proposals for audit firm rotation, except for proposals that would
      require rotation after a period of less than 5 years
--------------------------------------------------------------------------------


                                       10


      C. Compensation and Benefits

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

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
C.1   IN ACCORDANCE WITH THE RECOMMENDATION OF ISS on compensation plans if the
      ISS recommendation is based solely on whether or not the company's plan
      satisfies the allowable cap as calculated by ISS. If the recommendation of
      ISS is based on factors other than whether the plan satisfies the
      allowable cap the Committee will analyze the particular proposed plan.
      This policy applies to amendments of plans as well as to initial
      approvals.
--------------------------------------------------------------------------------
C.2   FOR proposals to eliminate retirement benefits for outside directors
--------------------------------------------------------------------------------
C.3   AGAINST proposals to establish retirement benefits for outside directors
--------------------------------------------------------------------------------
C.4   FOR proposals approving the remuneration of directors or of supervisory
      board members
--------------------------------------------------------------------------------
C.5   AGAINST proposals to reprice stock options
--------------------------------------------------------------------------------
C.6   FOR proposals to approve employee stock purchase plans that apply to all
      employees. This policy applies to proposals to amend ESPPs if the plan as
      amended applies to all employees.
--------------------------------------------------------------------------------
C.7   FOR proposals to pay retirement bonuses to directors of Japanese companies
      unless the directors have served less than three years
--------------------------------------------------------------------------------
C.8   AGAINST proposals seeking to pay outside directors only in stock
--------------------------------------------------------------------------------
C.9   FOR proposals seeking further disclosure of executive pay or requiring
      companies to report on their supplemental executive retirement benefits
--------------------------------------------------------------------------------
C.10  AGAINST proposals to ban all future stock or stock option grants to
      executives
--------------------------------------------------------------------------------
C.11  AGAINST option plans or grants that apply to directors or employees of
      "related companies" without adequate disclosure of the corporate
      relationship and justification of the option policy
--------------------------------------------------------------------------------
C.12  FOR proposals to exclude pension plan income in the calculation of
      earnings used in determining executive bonuses/compensation
--------------------------------------------------------------------------------


                                       11


      D. Capital Structure

      These proposals relate to various requests, principally from management,
for approval of amendments that would alter the capital structure of a company,
such as an increase in authorized shares. As a general matter, the Committee
will support requests that it believes enhance the rights of common shareholders
and oppose requests that appear to be unreasonably dilutive.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
D.1   AGAINST proposals seeking authorization to issue shares without preemptive
      rights except for issuances up to 10% of a non-US company's total
      outstanding capital
--------------------------------------------------------------------------------
D.2   FOR management proposals seeking preemptive rights or seeking
      authorization to issue shares with preemptive rights
--------------------------------------------------------------------------------
D.3   FOR management proposals approving share repurchase programs
--------------------------------------------------------------------------------
D.4   FOR management proposals to split a company's stock
--------------------------------------------------------------------------------
D.5   FOR management proposals to denominate or authorize denomination of
      securities or other obligations or assets in Euros
--------------------------------------------------------------------------------
D.6   FOR proposals requiring a company to expense stock options (unless the
      company has already publicly committed to do so by a certain date).
--------------------------------------------------------------------------------


                                       12


      E. Corporate Charter and By-Laws

      These proposals relate to various requests for approval of amendments to a
corporation's charter or by-laws, principally for the purpose of adopting or
redeeming "poison pills". As a general matter, the Committee opposes poison pill
provisions.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
E.1   AGAINST proposals seeking to adopt a poison pill
--------------------------------------------------------------------------------
E.2   FOR proposals seeking to redeem a poison pill
--------------------------------------------------------------------------------
E.3   FOR proposals seeking to have poison pills submitted to shareholders for
      ratification
--------------------------------------------------------------------------------
E.4   FOR management proposals to change the company's name
--------------------------------------------------------------------------------


                                       13


      F. Corporate Meetings

      These are routine proposals relating to various requests regarding the
formalities of corporate meetings.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
F.1   AGAINST proposals that seek authority to act on "any other business that
      may arise"
--------------------------------------------------------------------------------
F.2   FOR proposals designating two shareholders to keep minutes of the meeting
--------------------------------------------------------------------------------
F.3   FOR proposals concerning accepting or approving financial statements and
      statutory reports
--------------------------------------------------------------------------------
F.4   FOR proposals approving the discharge of management and the supervisory
      board
--------------------------------------------------------------------------------
F.5   FOR proposals approving the allocation of income and the dividend
--------------------------------------------------------------------------------
F.6   FOR proposals seeking authorization to file required documents/other
      formalities
--------------------------------------------------------------------------------
F.7   FOR proposals to authorize the corporate board to ratify and execute
      approved resolutions
--------------------------------------------------------------------------------
F.8   FOR proposals appointing inspectors of elections
--------------------------------------------------------------------------------
F.9   FOR proposals electing a chair of the meeting
--------------------------------------------------------------------------------
F.10  FOR proposals to permit "virtual" shareholder meetings over the Internet
--------------------------------------------------------------------------------
F.11  AGAINST proposals to require rotating sites for shareholder meetings
--------------------------------------------------------------------------------


                                       14


      G. Investment Companies

      These proposals relate to proxy issues that are associated solely with
holdings of shares of investment companies, including, but not limited to,
investment companies for which BlackRock provides investment advisory,
administrative and/or other services. As with other types of companies, the
Committee believes that a fund's Board of Directors (rather than its
shareholders) is best-positioned to set fund policy and oversee management.
However, the Committee opposes granting Boards of Directors authority over
certain matters, such as changes to a fund's investment objective, that the
Investment Company Act of 1940 envisions will be approved directly by
shareholders.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
G.1   FOR nominees for director of mutual funds in uncontested elections, except
      for nominees who
      o     have missed at least two meetings and, as a result, attended less
            than 75% of meetings of the Board of Directors and its committees
            the previous year, unless the nominee missed the meeting due to
            illness or fund business
      o     ignore a shareholder proposal that was approved by either a majority
            of the shares outstanding in any year or by the majority of votes
            cast for two consecutive years
      o     are interested directors who serve on the audit or nominating
            committees or on a full Board that does not have such committees
            composed exclusively of independent directors
      o     on a case-by-case basis, have served as directors of companies with
            allegedly poor corporate governance
--------------------------------------------------------------------------------
G.2   FOR the establishment of new series or classes of shares
--------------------------------------------------------------------------------
G.3   AGAINST proposals to change a fund's investment objective to
      nonfundamental
--------------------------------------------------------------------------------
G.4   FOR proposals to establish a master-feeder structure or authorizing the
      Board to approve a master-feeder structure without a further shareholder
      vote
--------------------------------------------------------------------------------
G.5   AGAINST a shareholder proposal for the establishment of a director
      ownership requirement
--------------------------------------------------------------------------------
G.6   FOR classified boards of closed-end investment companies
--------------------------------------------------------------------------------


                                       15


      H. Environmental and Social Issues

      These are shareholder proposals to limit 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 the 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.

      The Committee's general policy is to vote:

--------------------------------------------------------------------------------
H.1   AGAINST proposals seeking to have companies adopt international codes of
      conduct
--------------------------------------------------------------------------------
H.2   AGAINST proposals seeking to have companies provide non-required reports
      on:
      o     environmental liabilities;
      o     bank lending policies;
      o     corporate political contributions or activities;
      o     alcohol advertising and efforts to discourage drinking by minors;
      o     costs and risk of doing business in any individual country;
      o     involvement in nuclear defense systems
--------------------------------------------------------------------------------
H.3   AGAINST proposals requesting reports on Maquiladora operations or on CERES
      principles
--------------------------------------------------------------------------------
H.4   AGAINST proposals seeking implementation of the CERES principles
--------------------------------------------------------------------------------


                                       16

            (iv) Potential Material Conflicts of Interest

            BlackRock, Inc. and its affiliates (collectively, herein
            "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, 2007:

            Portfolio Manager Compensation

                  The portfolio manager compensation program of BlackRock 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 BlackRock portfolio
            managers are: 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, fixed 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,
            the portfolio manager incentive compensation is based on a formulaic
            compensation program.

                  BlackRock's formulaic portfolio manager compensation program
            includes: pre-tax investment performance relative to the appropriate
            competitors or benchmarks over 1-, 3- and 5-year performance periods
            and a measure of operational efficiency. If a portfolio manager's
            tenure is less than 5 years, performance periods will reflect time
            in position. Portfolio managers are compensated based on products
            they manage. For these purposes, the performance of the Fund is
            compared to the Lipper Closed-end Leveraged Insured Municipal Debt
            Funds classification. A smaller 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 the portfolio managers.

            Stock Bonus

                  A portion of the dollar value of the total annual
            performance-based bonus is paid in restricted shares of stock of
            BlackRock, Inc. (the "Company"). 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 Company stock price performance. As
            such, the stock bonus aligns each portfolio manager's financial
            interests with those of the Company's 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
            the Company's reputation for integrity.

            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. For example, BlackRock, Inc. has created a variety of



            incentive savings plans in which BlackRock employees are eligible to
            participate, including a 401(k) plan, the BlackRock Retirement
            Savings Plan (RSP) and the BlackRock Employee Stock Purchase Plan
            (ESPP). The employer contribution components of the RSP include a
            company match equal to 50% of the first 6% of eligible pay
            contributed to the plan capped at $4,000 per year, and a company
            retirement contribution equal to 3% of eligible compensation, plus
            an additional contribution of 2% for any year in which BlackRock has
            positive net operating income. The RSP offers a range of investment
            options, including registered investment companies managed by the
            firm. Company contributions follow the investment direction set by
            participants for their own contributions or absent, employee
            investment direction, are invested into a stable value fund. The
            ESPP allows for investment in BlackRock common stock at a 5%
            discount on the fair market value of the stock on the purchase date.
            Annual participation in the ESPP is limited to the purchase of 1,000
            shares or a dollar value of $25,000. Each portfolio manager is
            eligible to participate in these plans.

            (a)(4)   Beneficial Ownership of Securities. As of October 31,
                     2007, none of Messrs. Bock, Jaeckel or O'Connor
                     beneficially owned any stock issued by the Fund.
