A Letter to Shareholders

Dear Shareholder

For more than a year, investors have been besieged by a weak housing market, the bursting of the credit bubble that has

troubled the financial sector, and surging food and oil prices, which have stoked inflation concerns. Healthy nonfinancial

corporate profits and robust exporting activity remained among the few bright spots, helping the economy to grow at a

modest, but still positive, pace.

The Federal Reserve Board (the “Fed”) has been aggressive in its attempts to stimulate economic growth and stabilize

financial markets. In addition to slashing the target federal funds rate 325 basis points (3.25%) between September

2007 and April 2008, the central bank introduced the new Term Securities Lending Facility, granted broker-dealers access

to the discount window and used its own balance sheet to help negotiate the sale of Bear Stearns. However, the end of

the period saw a pause in Fed action; the central bank held the target rate steady at 2.0% as it attempted to balance

weak growth and inflationary pressures.

The Fed’s bold response to the financial crisis helped mitigate credit stress and investor anxiety, albeit temporarily.

U.S. equity markets sank sharply over the reporting period, notwithstanding a brief rally in the spring and another in

mid-summer, and international markets followed suit.

Treasury securities also traded in a volatile fashion, but generally rallied (yields fell as prices correspondingly rose), as

the broader flight-to-quality theme persisted. The yield on 10-year Treasury issues, which fell to 3.34% in March, climbed

to the 4.20% range in mid-June as investors temporarily shifted out of Treasury issues in favor of riskier assets (such as

stocks and other high-quality fixed income sectors), then reversed course and declined to 3.99% by period-end when

credit fears re-emerged. Meanwhile, tax-exempt issues underperformed their taxable counterparts, as problems among

municipal bond insurers and the failure in the market for auction rate securities continued to pressure the group.

Overall, the major benchmark indexes generated results that reflected heightened risk aversion:

Shortly before this shareholder report mailing, the investment landscape was dramatically altered as the ongoing

credit crisis intensified, resulting in a widespread breakdown in the financial services sector and unprecedented govern

ment intervention. Through periods of market turbulence, as ever, BlackRock's full resources are dedicated to the

management of our clients’ assets. For our most current views on the economy and financial markets, we invite you

Fund Summary as of July 31, 2008 BlackRock MuniHoldings Fund II, Inc.

Investment Objective

BlackRock MuniHoldings Fund II, Inc. (MUH) (the “Fund”) seeks to provide shareholders with current income exempt from federal income taxes 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.

Performance

For the 12 months ended July 31, 2008, the Fund returned (1.69)% based on market price and (2.30)% based on net asset value (“NAV”). For the
same period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of (4.15)% on a NAV basis. All
returns reflect reinvestment of dividends. Fund performance was positively impacted by three factors: a higher-quality bias amid a widening in credit
spreads; an emphasis on pre-refunded securities, which outperformed as the yield curve steepened; and a competitive dividend yield.
The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These
views are not intended to be a forecast of future events and are no guarantee of future results.

Fund Summary as of July 31, 2008 BlackRock MuniHoldings New Jersey Insured Fund, Inc.

Investment Objective

BlackRock MuniHoldings New Jersey Insured Fund, Inc. (MUJ) (the “Fund”) seeks to provide shareholders with current income exempt from federal
income tax and New Jersey personal income taxes by investing 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 tax and New Jersey personal income taxes.

Performance

For the 12 months ended July 31, 2008, the Fund returned (5.76)% based on market price and 1.35% based on NAV. For the same period, the
closed-end Lipper Single-State Insured Municipal Debt Funds category posted an average return of (1.42)% on a NAV basis. All returns reflect reinvest-
ment of dividends. The performance of the Lipper category does not necessarily correlate to that of the Fund, as the Lipper group comprises funds rep-
resenting various states and not New Jersey alone. Nevertheless, the Fund’s short duration position benefited performance during a period of rising tax-
exempt bond yields. Although the Fund increased its exposure to lower-rated bonds, limiting exposure to these issues also enhanced results, as these
issues significantly underperformed over the last year amid dramatic widening in credit spreads.

The Benefits and Risks of Leveraging

BlackRock MuniHoldings Fund II, Inc. and BlackRock MuniHoldings
New Jersey Insured Fund, Inc. (each a “Fund” and, collectively, the
“Funds”) utilize leverage to seek to enhance the yield and NAV 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 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 invest-
ments, and therefore the Common Stock shareholders are the benefici-
aries 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 NAV 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 NAV,
the market value of the fund’s Common Stock may also decline.

In addition, the Funds may from time to time leverage their assets
through the use of tender option bond (“TOB”) programs. In a typical
TOB program, the Fund transfers one or more municipal bonds to a TOB
trust, which issues short-term variable rate securities to third-party
investors and a residual interest to the Fund. The cash received by the
TOB trust from the issuance of the short-term securities (less transaction
expenses) is paid to the Fund, which invests the cash in additional port-
folio securities. The distribution rate on the short-term securities is reset
periodically (typically every seven days) through a remarketing of the
short-term securities. Any income earned on the bonds in the TOB trust,
net of expenses incurred by the TOB trust, that is not paid to the holders
of the short-term securities is paid to the Fund. In connection with man-
aging the Funds’ assets, the Funds’ investment advisor may at any time
retrieve the bonds out of the TOB trust typically within seven days. TOB
investments generally will provide the Funds with economic benefits in
periods of declining short-term interest rates, but expose the Funds to
risks during periods of rising short-term interest rates similar to those
associated with Preferred Stock issued by the Funds, as described
above. Additionally, fluctuations in the market value of municipal secu-
rities deposited into the TOB trust may adversely affect the Funds’ NAVs
per share. (See Note 1 of the Notes to Financial Statements for details
of municipal bonds transferred to TOB trusts.)

Under the Investment Company Act of 1940, the Funds are permitted to
issue Preferred Stock in an amount up to 50% of their total managed
assets at the time of issuance. Each Fund also anticipates that its
total economic leverage from Preferred Stock and TOBs will not exceed
50% of its total managed assets. As of July 31, 2008, BlackRock
MuniHoldings Fund II, Inc. and BlackRock MuniHoldings New Jersey
Insured Fund, Inc. had leverage from Preferred Stock and TOBs of 39%
and 41% of their total managed assets, respectively.

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 securi-
ties. Swap agreements involve the risk that the party with whom each
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.

JULY 31, 2008

Notes to Financial Statements

1. Significant Accounting Policies:

BlackRock MuniHoldings Fund II, Inc. and BlackRock MuniHoldings New
Jersey Insured Fund, Inc. (the “Funds” or individually as the “Fund”), are
registered under the Investment Company Act of 1940, as amended,
(the “1940 Act”) as non-diversified, closed-end management investment
companies. The Funds’ financial statements are prepared in conformity
with accounting principles generally accepted in the United States of
America, which may require the use of management accruals and esti-
mates. Actual results may differ from these estimates. The Funds deter-
mine, and make available for publication, the net asset values of their
Common Stock on a daily basis.

The following is a summary of significant accounting policies followed
by the Funds:

Valuation of Investments: Municipal investments (including commit-
ments to purchase such investments on a “when-issued” basis) are
valued on the basis of prices provided by dealers or pricing services
selected under the supervision of each Fund’s Board of Directors (the
“Board”). In determining the value of a particular investment, pricing
services may use certain information with respect to transactions in
such investments, quotations from dealers, pricing matrixes, market
transactions in comparable investments and various relationships
between investments. Swaps are valued by quoted fair values received
daily by each Fund’s pricing service or through brokers. Short-term secu-
rities are valued at amortized cost. Investments in open-end investment
companies are valued at net asset value each business day.

In the event that application of these methods of valuation results in
a price for an investment which is deemed not to be representative of
the market value of such investment, the investment will be valued by
a method approved by the Board as reflecting fair value (“Fair Value
Assets”). When determining the price for Fair Value Assets, the invest-
ment advisor and/or sub-advisor seeks to determine the price that the
Funds might reasonably expect to receive from the current sale of that
asset in an arm’s-length transaction. Fair value determinations shall be
based upon all available factors that the investment advisor and/or sub-
advisor deems relevant. The pricing of all Fair Value Assets is subse-
quently reported to the Board or a committee thereof.

Derivative Financial Instruments: The Funds may engage in various
portfolio investment strategies both to increase the return of the Funds
and to hedge, or protect, their exposure to interest rate movements
and movements in the securities markets. Losses may arise if the value
of the contract decreases due to an unfavorable change in the price of
the underlying security or if the counterparty does not perform under
the contract.

_•_{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. Changes in the value of the forward
interest rate swap are recognized as unrealized gains and losses.
When the agreement is closed, the Funds record a realized gain or
loss in an amount equal to the value of the agreement. The Funds
generally intend to close each forward interest rate swap before
the effective date specified in the agreement and therefore avoid
entering into the interest rate swap underlying each forward interest
rate swap.

Forward Commitments and When-Issued Delayed Delivery Securities:
The Funds may purchase securities on a when-issued basis and may
purchase or sell securities on a forward commitment basis. Settlement
of such transactions normally occurs within a month or more after the
purchase or sale commitment is made. The Funds may purchase securi-
ties under such conditions only with the intention of actually acquiring
them, but may enter into a separate agreement to sell the securities
before the settlement date. Since the value of securities purchased may
fluctuate prior to settlement, the Funds may be required to pay more at
settlement than the security is worth. In addition, the purchaser is not
entitled to any of the interest earned prior to settlement. Upon making a
commitment to purchase a security on a when-issued basis, the Funds
will hold liquid assets worth at least the equivalent of the amount due.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Funds
leverage their assets through the use of tender option bond trusts
(“TOBs”). A TOB is established by a third party sponsor forming a special
purpose entity, into which one or more funds, or an agent on behalf of
the funds, transfers municipal securities. Other funds managed by the
investment advisor may also contribute municipal securities to a TOB
into which each Fund has contributed 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 (“TOB
Residuals”), which are generally issued to the participating fund that
made the transfer. The TOB Residuals held by the Funds include the right
of each 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, within seven days, a corresponding share of the municipal secu-
rities from the TOB to the Fund. The cash received by the TOB from the
sale of the short-term floating rate certificates, less transaction expens-
es, is paid to the Fund, which typically invests the cash in additional
municipal securities. Each Fund’s transfer of the municipal securities to
a TOB is accounted for as a secured borrowing, 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 of the Funds.

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

ANNUAL REPORT

JULY 31, 2008

Notes to Financial Statements (continued)

services to a TOB are reported as expenses of the Funds. 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. As of July 31, 2008, the aggregate value of the
underlying municipal securities transferred to TOBs, the related liability
for trust certificates and the range of interest rates were as follows:

Underlying
Municipal
	Securities	Liability	Range of
	Transferred	for Trust	Interest
	to TOBs	Certificates	Rates

BlackRock MuniHoldings			1.685% –
Fund II, Inc	$64,193,073	$38,411,348	2.954%
BlackRock MuniHoldings
New Jersey			1.739% –
Insured Fund, Inc	$50,560,868	$31,822,920	2.084%

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, each Fund’s investment in TOBs likely will adversely
affect each Fund’s investment income and dividends to Common Stock
shareholders. Fluctuations in the market value of municipal securities
deposited into the TOB may adversely affect each Fund’s net asset
value per share.

Zero-Coupon Bonds: The Funds may invest in zero-coupon bonds,
which are normally issued at a significant discount from face value and
do not provide for periodic interest payments. Zero-coupon bonds may
experience greater volatility in market value than similar maturity debt
obligations which provide for regular interest payments.

Segregation: In cases in which the 1940 Act and the interpretive posi-
tions of the Securities and Exchange Commission (“SEC”) require that
the Funds segregate assets in connection with certain investments
(e.g., swaps) and certain borrowings, each Fund will, consistent with
certain interpretive letters issued by the SEC, designate on its books
and records cash or other liquid debt securities having a market value
at least equal to the amount that would otherwise be required to be
physically segregated.

Investment Transactions and Investment Income: Investment trans-
actions 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
method. The Funds amortize all premiums and discounts on debt
securities.

Dividends and Distributions: Dividends from net investment income
are declared and paid monthly. Distributions of capital gains are record-
ed on the ex-dividend dates. Dividends and distributions to Preferred
Stock shareholders are accrued and determined as described in Note 4.

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.

Effective January 31, 2008, the Funds implemented Financial
Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting
for Uncertainty in Income Taxes — an interpretation of FASB Statement
No. 109” (“FIN 48”). FIN 48 prescribes the minimum recognition thresh-
old a tax position must meet in connection with accounting for uncer-
tainties in income tax positions taken or expected to be taken by an
entity, including investment companies, before being measured and
recognized in the financial statements. The investment advisor has evalu-
ated the application of FIN 48 to each Fund, and has determined that
the adoption of FIN 48 does not have a material impact on each Fund’s
financial statements. The Funds file U.S. federal and various state and
local tax returns. No income tax returns are currently under examination.
The statute of limitations on each Fund’s U.S. federal tax return remains
open for the years ended July 31, 2005 through July 31, 2007. The
statutes of limitations on each Fund’s state and local tax returns may
remain open for an additional year depending upon the jurisdiction.

Recent Accounting Pronouncements: 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 frame-
work for measuring fair value and expands disclosures about fair value
measurements. The impact on each Fund’s financial statement disclo-
sures, if any, is currently being assessed.

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. 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. The
impact on each Fund’s financial statement disclosures, if any, is currently
being assessed.

In March 2008, Statement of Financial Accounting Standards No. 161,
“Disclosures about Derivative Instruments and Hedging Activities — an
amendment of FASB Statement No. 133” (“FAS 161”), was issued and
is effective for fiscal years beginning after November 15, 2008. FAS 161

22 ANNUAL REPORT

is intended to improve financial reporting for derivative instruments by
requiring enhanced disclosure that enables investors to understand how
and why an entity uses derivatives, how derivatives are accounted for,
and how derivative instruments affect an entity’s results of operations
and financial position. The impact on each Fund’s financial statement
disclosures, if any, is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent
Investment Plan: Under the deferred compensation plan approved by
each Fund’s Board, non-interested Directors (“Independent Directors”)
may defer a portion of their annual complex-wide compensation.
Deferred amounts earn an approximate return as though equivalent dol-
lar amounts have been invested in common shares of other certain
BlackRock Closed-End Funds selected by the Independent Directors.
This has approximately the same economic effect for the Independent
Directors as if the Independent Directors had invested the deferred
amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations there-
under represent general unsecured claims against the general assets of
each Fund. Each Fund may, however, elect to invest in common stock of
other certain BlackRock Closed-End Funds selected by the Independent
Directors in order to match its deferred compensation obligations.

Other: Expenses directly related to each Fund are charged to that
Fund. Other operating expenses shared by several funds are pro-rated
among those funds on the basis of relative net assets or other
appropriate methods.

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

Each Fund has entered into an Investment Advisory Agreement with
BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned sub-
sidiary of BlackRock, Inc., to provide investment advisory and adminis-
tration services. Merrill Lynch & Co., Inc. (“Merrill Lynch”) and The PNC
Financial Services Group, Inc. are principal owners of BlackRock, Inc.

The Advisor is responsible for the management of each Fund’s portfolio
and provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of each Fund. For such
services, each Fund pays the Advisor a monthly fee at an annual rate
of 0.55% of each Fund’s average daily net assets. Average daily net
assets is the average daily value of the Fund’s total assets minus the
sum of its accrued liabilities.

The Advisor has voluntarily agreed to waive its advisory fee on the pro-
ceeds of Preferred Stock and TOBs that exceeds 35% of the average
daily net assets of BlackRock MuniHoldings New Jersey Insured Fund,
Inc. For the year ended July 31, 2008, the amount was $195,615.
This amount is included in fees waived by advisor on the Statements
of Operations.

The Advisor has agreed to waive its advisory fee by the amount of invest-
ment advisory fees each Fund pays to the Advisor indirectly through its
investment in affiliated money market funds. This amount is included in
fees waived by advisor on the Statements of Operations. For the year
ended July 31, 2008, the amounts were as follows:

		Fees Waived by Advisor

BlackRock MuniHoldings Fund II, Inc		$ 22
BlackRock MuniHoldings New Jersey Insured Fund, Inc		$43,185

The Advisor has entered into separate sub-advisory agreements with
BlackRock Investment Management, LLC (“BIM”), an affiliate of the
Advisor, with respect to each Fund, under which the Advisor pays BIM
for services it provides, a monthly fee that is a percentage of the invest-
ment advisory fee paid by each Fund to the Advisor.

For the year ended July 31, 2008, the Funds reimbursed the Advisor for
certain accounting services, which are included in accounting services
on the Statements of Operations. The reimbursements were as follows:

		Reimbursement
		to the Advisor

BlackRock MuniHoldings Fund II, Inc		$4,203
BlackRock MuniHoldings New Jersey Insured Fund, Inc		$8,721

Certain officers and/or directors of the Funds are officers and/or direc-
tors of BlackRock, Inc. or its affiliates. The Funds reimburse the Advisor
for compensation paid to the Funds’ Chief Compliance Officer.

3. Investments:

Purchases and sales of investments, excluding short-term securities,
for the year ended July 31, 2008 were as follows:

Total Purchases	$74,739,607	$61,766,470
Total Sales	$72,930,367	$65,548,399


4. Capital Stock Transactions:

Each Fund is authorized to issue 200,000,000 shares of stock, includ-
ing Preferred Stock, par value $0.10 per share, all of which were initially
classified as Common Stock. Each Board is authorized, however, to
reclassify any unissued shares of common stock without approval of
the holders of Common Stock.

Common Stock

BlackRock MuniHoldings Fund II, Inc.

Shares issued and outstanding during the year ended July 31, 2008

Preferred Stock

Preferred Stock of the Funds has a par value of $0.10 per share and a
liquidation preference of $25,000 per share, plus accrued and unpaid
dividends, that entitles their holders to receive cash dividends at varying
annualized rates for each dividend period. The yields in effect at July 31,
2008 were as follows:

		BlackRock
		MuniHoldings
	BlackRock	New Jersey
	MuniHoldings	Insured

Series B	3.579%	3.579%
Series C	—	3.503%
Series D	—	3.427%
Series E	—	3.579%

Each Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate of 0.25%, calculated on the aggregate
principal amount. For the year ended July 31, 2008, Merrill Lynch,
Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of
Merrill Lynch, earned commissions as follows:

		Commissions

BlackRock MuniHoldings Fund II, Inc		$ 80,144
BlackRock MuniHoldings New Jersey Insured Fund, Inc		$265,947

On June 4, 2008, the Funds announced the following redemptions of
Preferred Stock at a price of $25,000 per share plus any accrued and
unpaid dividends through the redemption date:

BlackRock	Redemption	Stock	Aggregate
MuniHoldings Fund II, Inc.	Date	Redeemed	Principal

Series A	6/25/08	520	$13,000,000
Series B	6/23/08	520	$13,000,000




BlackRock MuniHoldings	Redemption	Stock	Aggregate
New Jersey Insured Fund, Inc.	Date	Redeemed	Principal

Series A	6/24/08	176	$ 4,400,000
Series B	6/27/08	176	$ 4,400,000
Series C	6/25/08	311	$ 7,775,000
Series D	6/26/08	244	$ 6,100,000
Series E	6/23/08	145	$ 3,625,000

The Funds financed the Preferred Stock redemptions with cash received
from TOB transactions.

Shares issued and outstanding during the year ended July 31, 2007
remained constant.

Dividends on seven-day Preferred Stock are cumulative at a rate which
is reset every seven days based on the results of an auction. If the
Preferred Stock fails to clear the auction on an auction date, each Fund
is required to pay the maximum applicable rate on the Preferred Stock
to holders of such shares for successive dividend periods until such time
as the stock is successfully auctioned. The maximum applicable rate on
the Preferred Stock is the higher of 110% of the AA commercial paper
rate or 110% of 90% of the Kenny S&P 30-day High Grade Index rate
divided by 1.00 minus the marginal tax rate. For the year ended July 31,
2008, the Preferred Stock of each Fund was successfully auctioned at
each auction date until February 13, 2008. The low, high and average
dividend rates on the Preferred Stock for each Fund for the year ended
July 31, 2008 were as follows:

BlackRock MuniHoldings Fund II, Inc.


	Low	High	Average

Series A	2.535%	4.750%	3.490%
Series B	2.535%	4.60%	3.464%


BlackRock MuniHoldings New Jersey Insured Fund, Inc.


	Low	High	Average

Series A	1.900%	4.508%	3.311%
Series B	1.500%	4.508%	3.243%
Series C	2.535%	4.356%	3.353%
Series D	2.480%	4.356%	3.312%
Series E	2.483%	4.508%	3.309%

Since February 13, 2008, the Preferred Stock of the Funds failed to
clear any of their auctions. As a result, the Preferred Stock dividend rates
were reset to the maximum applicable rate, which ranged from 2.458%
to 4.508% . A failed auction is not an event of default for the Fund but it
has a negative impact on the liquidity of the Preferred Stock. A failed
auction occurs when there are more sellers of a Fund’s auction rate pre-
ferred stock than buyers. It is impossible to predict how long this imbal-
ance will last. A successful auction for the Funds’ Preferred Stock may
not occur for some time, if ever, and even if liquidity does resume, hold-
ers of Preferred Stock may not have the ability to sell the Preferred Stock
at its liquidation preference.

The Funds may not declare dividends or make other distributions on
Common Stock or purchase any such shares if, at the time of the
declaration, distribution or purchase, asset coverage with respect to
the outstanding Preferred Stock is less than 200%.

24 ANNUAL REPORT

JULY 31, 2008

Notes to Financial Statements (continued)

The Preferred Stock is redeemable at the option of each Fund, in whole or
in part, on any dividend payment date at $25,000 per share plus
any accumulated and unpaid dividends whether or not declared. The
Preferred Stock is also subject to mandatory redemption at $25,000
per share plus any accumulated and unpaid dividends, whether or not
declared, if certain requirements relating to the composition of the assets
and liabilities of each Fund, as set forth in each Fund’s Articles Supple-
mentary, are not satisfied.

The holders of Preferred Stock have voting rights equal to the holders of
Common Stock (one vote per share) and will vote together with holders of
Common Stock (one vote per share) as a single class. However, the holders
of Preferred Stock, voting as a separate class, are also entitled to elect two
Directors for a Fund. In addition, the 1940 Act requires that along with
approval by shareholders that might otherwise be required, the approval
of the holders of a majority of any outstFanding Preferred Stock, voting
separately as a class, would be required to (a) adopt any plan of reorgani-
zation that would adversely affect the Preferred Stock (b) change a Fund’s
sub-classification as a closed-end investment company or change its
fundamental investment restrictions or (c) change its business so as to
cease to be an investment company.

5. Income Tax Information:

Reclassifications: Accounting principles generally accepted in the United
States of America require that certain components of net assets be
adjusted to reflect permanent differences between financial and tax
reporting. Accordingly, during the current year, $455,008 has been reclas-
sified in BlackRock MuniHoldings Fund II, Inc. between paid-in capital in
excess of par and accumulated net realized loss and $189,649 has been
reclassified between accumulated net realized loss and undistributed net
investment income as a result of permanent differences attributable to
expiration of capital loss carryforwards, amortization methods on fixed
income securities and reclassification of distributions. These reclassifica-
tions have no effect on net assets or net asset value per share.

BlackRock MuniHoldings Fund II, Inc.

The tax character of distributions paid during the fiscal years ended
July 31, 2008 and July 31, 2007 was as follows:

	7/31/2008	7/31/2007

Distributions paid from:
Tax-exempt income	$11,399,342	$11,685,098
Ordinary income	42,062	—

Total distributions	$11,441,404	$11,685,098

As of July 31, 2008, the components of accumulated loss on a tax basis
were as follows:

Undistributed tax-exempt net income		$ 1,004,433
Ordinary income		75,519

Total undistributed net earnings		1,079,952
Capital loss carryforward		(12,986,594)*
Net unrealized losses		(1,415,966)**

Total accumulated net loss		$ (13,322,608)

* On July 31, 2008, the Fund had a capital loss carryforward of $12,986,594, of
which $12,107,981 expires in 2009, $689,205 expires in 2010 and $189,408
expires in 2011. This amount will be available to offset future realized capital gains
** The difference between book-basis and tax-basis net unrealized losses is attribut-
able primarily to the difference between the book and tax treatment of residual
interests in tender option bond trusts and the difference between book and tax
amortization methods for premiums and discounts on fixed income securities.

BlackRock MuniHoldings New Jersey Insured Fund, Inc.

The tax character of distributions paid during the fiscal years ended
July 31, 2008 and July 31, 2007 was as follows:

	7/31/2008	7/31/2007

Distributions paid from:
Tax-exempt income	$20,713,946	$22,294,792

Total distributions	$20,713,946	$22,294,792

As of July 31, 2008, the components of accumulated loss on a
tax basis were as follows:

Undistributed tax-exempt net income		$ 868,477

Total undistributed net earnings		868,477
Capital loss carryforward		(22,781,740)*
Net unrealized gains		5,347,282**

Total accumulated net loss		$ (16,565,981)

* On July 31, 2008, the Fund had a capital loss carryforward of $22,781,740 of
which $22,545,846 expires in 2009 and $235,894 expires in 2011. This amount
will be available to offset future realized capital gains.
** The difference between book-basis and tax-basis net unrealized gains is attributable
primarily to the tax deferral of losses on straddles, the difference between book and
tax amortization methods for premiums and discounts on fixed income securities, the
deferral of post-October capital losses for tax purposes and the difference between
the book and tax treatment of residual interests in tender option bond trusts.

6. Concentration Risk:

Each Fund’s investments are concentrated in certain states, which may be
affected by adverse financial, social, environmental, economic, regulatory
and political factors.

Many municipalities insure repayment of their bonds, which reduces the
risk of loss due to issuer default. The market value of these bonds may
fluctuate for other reasons, including market perception of the value of
such insurance, and there is no guarantee that the insurer will meet
its obligation.

7. Restatement Information:

Subsequent to the initial issuance of their July 31, 2006 financial state-
ments, the Funds determined that the criteria for sale accounting 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 the years ended
July 31, 2005 and July 31, 2004 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.

Series E	—	$ 65,988

On September 12, 2008, the Board of Directors of BlackRock
MuniHoldings New Jersey Insured Fund, Inc. voted unanimously to
change certain investment guidelines of the Fund. Under normal market
conditions, the Fund is required to invest at least 80% of its total assets
in municipal bonds either (i) insured under an insurance policy pur-
chased by the Fund or (ii) insured under an insurance policy obtained
by the issuer of the municipal bond or any other party. Historically, the
Fund has had an additional non-fundamental investment policy limiting
its purchase of insured municipal bonds to those bonds insured by
insurance providers with claims-paying abilities rated AAA or Aaa at
the time of investment.

Following the onset of the credit and liquidity crises currently troubling
the financial markets, the applicable rating agencies lowered the claims-
paying ability rating of most of the municipal bond insurance providers
below the highest rating category. As a result, the Advisor recommended,
and the Board approved, an amended policy with respect to the pur-
chase of insured municipal bonds that such bonds must be insured by
insurance providers or other entities with claims-paying abilities rated at
least investment grade. This investment grade restriction is measured at
the time of investment, and the Fund will not be required to dispose of
municipal bonds it holds in the event of subsequent downgrades. The
approved changes do not alter the Fund’s investment objective.

The Advisor and the Board believe the amended policy will allow the
Advisor to better manage the Fund’s portfolio in the best interests of the
Fund’s shareholders and to better meet the Fund’s investment objective.

On September 15, 2008, Bank of America Corporation announced that
it has agreed to acquire Merrill Lynch, one of the principal owners of
BlackRock, Inc. The purchase has been approved by the directors of
both companies. Subject to shareholder and regulatory approvals, the
transaction is expected to close in the first quarter of 2009.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Boards of Directors of BlackRock
MuniHoldings Fund II, Inc. and BlackRock MuniHoldings
New Jersey Insured Fund, Inc.:

We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of BlackRock MuniHoldings Fund
II, Inc. and BlackRock MuniHoldings New Jersey Insured Fund, Inc. (the
"Funds") as of July 31, 2008, and the related statements of operations
for the year then ended and 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 three years in the period then ended. 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 based on our audits. The
financial highlights for each of the two years in the period ended July
31, 2005 (before the restatement described in Note 7) were audited by
other auditors whose report, dated September 12, 2005, expressed a
qualified opinion on those financial highlights because of the errors
described in Note 7.

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 audits to obtain reasonable assur-
ance 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, an audit of their internal control over finan-
cial 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 finan-
cial 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 July 31, 2008, by
correspondence with the custodian and brokers. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights of
BlackRock MuniHoldings Fund II, Inc. and BlackRock MuniHoldings New
Jersey Insured Fund, Inc. referred to above, present fairly, in all material
respects, their financial position as of July 31, 2008, the results of their
operations for the year then ended and 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 three years in the period then ended, in con-
formity 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 for each of the two years in the period
ended July 31, 2005 to correct the errors described in Note 7. These
adjustments are the responsibility of the Funds' 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 adjust-
ments are appropriate and have been properly applied, in all material
respects, to the restated financial highlights for each of the two years
in the period ended July 31, 2005. We did not perform any audit proce-
dures designed to assess whether any additional adjustments to such
financial highlights might be necessary in order for such financial high-
lights to be presented in conformity with generally accepted accounting
principles. In our opinion, the adjustments to the financial highlights for
each of the two years in the period ended July 31, 2005 described in
Note 7 are appropriate and have been properly applied, in all material
respects. However, we were not engaged to audit, review, or apply any
procedures to such financial highlights other than with respect to the
adjustments described in Note 7 and, accordingly, we do not express
an opinion or any other form of assurance on such financial highlights.

28 ANNUAL REPORT

JULY 31, 2008

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 a
Fund are automatically reinvested in additional shares of Common Stock
of the Fund. The Plan is administered on behalf of the shareholders by
BNY Mellon Shareowner Services (the “Plan Agent”). Under the Plan,
whenever a 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
Funds (“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 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 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 volun-
tary 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 a 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 the Funds do 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 partici-
pating in the Plan. The Plan Agent’s service fees for handling the rein-
vestment 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 distri-
butions 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. Participation in the Plan generally will
not effect the tax-exempt status of exempt interest dividends paid by the
Funds. 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 por-
tion of the discount from the market value (which may not exceed 5% of
the fair market value of the Funds’ 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, includ-
ing any questions about the Plan, should be directed to the Plan Agent
at BNY Mellon Shareowner Services, .O. Box 358035, Pittsburgh, PA
15252-8035, Telephone: (866) 216-0242.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Directors (collectively, the “Board,” the members of
which are referred to as “Directors”) of the BlackRock MuniHoldings
Fund II, Inc. (“MUH”) and BlackRock MuniHoldings New Jersey Insured
Fund, Inc. (“MUJ,” and together with MUH, the “Funds”) met in April
and May 2008 to consider approving the continuation of each Fund’s
investment advisory agreement (each, an “Advisory Agreement”) with
BlackRock Advisors, LLC (the “Advisor”), each Fund’s investment adviser.
The Board also considered the approval of each Fund’s subadvisory
agreement (each, a “Subadvisory Agreement” and, together with the
“Advisory Agreement,” the “Agreements”) between the Advisor and
BlackRock Investment Management, LLC (the “Subadvisor”). The Advisor
and the Subadvisor are collectively referred to herein as the “Advisors”
and, together with BlackRock, Inc., “BlackRock.”

Activities and Composition of the Board

The Board of each Fund consists of thirteen individuals, eleven of whom
are not “interested persons” of the Funds as defined in the Investment
Company Act of 1940 (the “1940 Act”) (the “Independent Directors”).
The Directors are responsible for the oversight of the operations of the
Funds and perform the various duties imposed on the directors of invest-
ment companies by the 1940 Act. The Independent Directors have
retained independent legal counsel to assist them in connection with
their duties. The Chairman of the Board is an Independent Director. The
Board has established four standing committees: an Audit Committee, a
Governance and Nominating Committee, a Compliance Committee and
a Performance Oversight Committee.

Advisory Agreement and Subadvisory Agreement

Upon the consummation of the combination of BlackRock, Inc.’s invest-
ment management business with Merrill Lynch & Co., Inc.’s investment
management business, including Merrill Lynch Investment Managers, L. .,
and certain affiliates, each Fund entered into an Advisory Agreement and
a Subadvisory Agreement, each with an initial two-year term. Consistent
with the 1940 Act, after the Advisory Agreement’s and Subadvisory
Agreement’s respective initial two-year term, the Board is required to
consider the continuation of each Fund’s Advisory Agreement and
Subadvisory Agreement on an annual basis. In connection with this
process, the Board assessed, among other things, the nature, scope
and quality of the services provided to each Fund by the personnel of
BlackRock and its affiliates, including investment advisory services,
administrative services, secondary market support services, oversight of
fund accounting and custody, and assistance in meeting legal and regu-
latory requirements. The Board also received and assessed information
regarding the services provided to each Fund by certain unaffiliated
service providers.

Throughout the year, the Board also considered a range of information in
connection with its oversight of the services provided by BlackRock and
its affiliates. Among the matters the Board considered were: (a) invest-
ment performance for one-, three- and five-year periods, as applicable,
against peer funds, as well as senior management and portfolio man-
agers’ analysis of the reasons for underperformance, if applicable;
(b) fees, including advisory, administration and other fees paid to
BlackRock and its affiliates by each Fund, as applicable; (c) Fund oper-
ating expenses paid to third parties; (d) the resources devoted to and
compliance reports relating to each Fund’s investment objective, policies
and restrictions; (e) each Fund’s compliance with its Code of Ethics and
compliance policies and procedures; (f) the nature, cost and character
of non-investment management services provided by BlackRock and its
affiliates; (g) BlackRock’s and other service providers’ internal controls;
(h) BlackRock’s implementation of the proxy voting guidelines approved
by the Board; (i) execution quality; (j) valuation and liquidity procedures;
and (k) reviews of BlackRock’s business, including BlackRock’s response
to the increasing scale of its business.

Board Considerations in Approving the Advisory
Agreement and Subadvisory Agreement

To assist the Board in its evaluation of the Agreements, the Directors
received information from BlackRock in advance of the April 22, 2008
meeting which detailed, among other things, the organization, business
lines and capabilities of the Advisors, including: (a) the responsibilities
of various departments and key personnel and biographical information
relating to key personnel; (b) financial statements for BlackRock; (c) the
advisory and/or administrative fees paid by each Fund to the Advisors,
including comparisons, compiled by Lipper Inc. (“Lipper”), an independ-
ent third party, with the management fees, which include advisory and
administration fees, of funds with similar investment objectives (“Peers”);
(d) the profitability of BlackRock and certain industry profitability analy-
ses for advisers to registered investment companies; (e) the expenses
of BlackRock in providing various services; (f) non-investment advisory
reimbursements, if applicable, and “fallout” benefits to BlackRock;
(g) economies of scale, if any, generated through the Advisors’ manage-
ment of all of the BlackRock closed-end funds (the “Fund Complex”);
(h) the expenses of each Fund, including comparisons of each such
Fund’s expense ratios (both before and after any fee waivers) with the
expense ratios of its Peers; (i) an internal comparison of management
fees classified by Lipper, if applicable; and (j) each Fund’s performance
for the past one-, three- and five-year periods, as applicable, as well as
each Fund’s performance compared to its Peers.

The Board also considered other matters it deemed important to the
approval process, where applicable, such as payments made to
BlackRock or its affiliates relating to the distribution of Fund shares,
services related to the valuation and pricing of Fund portfolio holdings,
and direct and indirect benefits to BlackRock and its affiliates from their
relationship with the Funds.

30 ANNUAL REPORT

JULY 31, 2008

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

In addition to the foregoing materials, independent legal counsel to the
Independent Directors provided a legal memorandum outlining, among
other things, the duties of the Board under the 1940 Act, as well as the
general principles of relevant law in reviewing and approving advisory
contracts, the requirements of the 1940 Act in such matters, an adviser’s
fiduciary duty with respect to advisory agreements and compensation,
and the standards used by courts in determining whether investment
company boards of directors have fulfilled their duties and the factors
to be considered by boards in voting on advisory agreements.

The Independent Directors reviewed this information and discussed it
with independent legal counsel prior to the meeting on April 22, 2008.
At the Board meeting on April 22, 2008, BlackRock made a presenta-
tion to and responded to questions from the Board. Following the meet-
ing on April 22, 2008, the Board presented BlackRock with questions
and requests for additional information. BlackRock responded to these
requests with additional written materials provided to the Directors prior
to the meetings on May 29 and 30, 2008. At the Board meetings on
May 29 and 30, 2008, BlackRock responded to further questions from
the Board. In connection with BlackRock’s presentations, the Board con-
sidered each Agreement and, in consultation with independent legal
counsel, reviewed the factors set out in judicial decisions and Securities
and Exchange Commission (“SEC”) statements relating to the renewal
of the Agreements.

Matters Considered by the Board

In connection with its deliberations with respect to the Agreements, the
Board considered all factors it believed relevant with respect to each
Fund, including the following: the nature, extent and quality of the ser-
vices provided by the Advisors; the investment performance of each
Fund; the costs of the services to be provided and profits to be realized
by the Advisors and their affiliates from their relationship with the Funds;
the extent to which economies of scale would be realized as the Fund
Complex grows; and whether BlackRock realizes other benefits from its
relationship with the Funds.

A. Nature, Extent and Quality of the Services: In evaluating the nature,
extent and quality of the Advisors’ services, the Board reviewed informa-
tion concerning the types of services that the Advisors provide and are
expected to provide to each Fund, narrative and statistical information
concerning each Fund’s performance record and how such performance
compares to each Fund’s Peers, information describing BlackRock’s
organization and its various departments, the experience and responsi-
bilities of key personnel and available resources. The Board noted the
willingness of the personnel of BlackRock to engage in open, candid dis-
cussions with the Board. The Board further considered the quality of the
Advisors’ investment process in making portfolio management decisions.

In addition to advisory services, the Directors considered the quality of
the administrative and non-investment advisory services provided to the
Funds. The Advisors and their affiliates provided each Fund with such
administrative and other services, as applicable (in addition to any such
services provided by others for the Funds), and officers and other
personnel as are necessary for the operations of the respective Fund.
In addition to investment management services, the Advisors and their
affiliates provided each Fund with services such as: preparing share-
holder reports and communications, including annual and semi-annual
financial statements and the Funds’ websites; communications with ana-
lysts to support secondary market trading; assisting with daily account-
ing and pricing; preparing periodic filings with regulators and stock
exchanges; overseeing and coordinating the activities of other service
providers; administering and organizing Board meetings and preparing
the Board materials for such meetings; providing legal and compliance
support (such as helping to prepare proxy statements and responding
to regulatory inquiries); and performing other Fund administrative tasks
necessary for the operation of the respective Fund (such as tax reporting
and fulfilling regulatory filing requirements). The Board considered the
Advisors’ policies and procedures for assuring compliance with appli-
cable laws and regulations.

B. The Investment Performance of the Funds and BlackRock: As previ-
ously noted, the Board received performance information regarding each
Fund and its Peers. Among other things, the Board received materials
reflecting each Fund’s historic performance and each Fund’s perform-
ance compared to its Peers. More specifically, each Fund’s one-, three-
and five-year total returns (as applicable) were evaluated relative to its
Peers (including the Peers’ median performance).

The Board reviewed a narrative and statistical analysis of the Lipper
data that was prepared by BlackRock, which analyzed various factors
that affect Lipper rankings.

The Board noted that in general MUH performed better than its Peers in
that its performance was at or above the median in at least two of the
one-, three- and five-year periods reported.

The Board noted that, although MUJ underperformed its Peers in at least
two of the one-, three- and five-year periods reported, its underperfor-
mance was not greater than 10% of the median return of its Peers for
any of the periods above and therefore not considered to be material.
The Board concluded that BlackRock was committed to providing the
resources necessary to assist the portfolio managers and to continue
improving MUJ’s performance. Based on its review, the Board generally
was satisfied with BlackRock’s efforts to manage the Fund.

ANNUAL REPORT

JULY 31, 2008

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

After considering this information, the Boards concluded that the per-
formance of each Fund, in light of and after considering the other facts
and circumstances applicable to each Fund, supports a conclusion that
each Fund’s Agreements should be renewed.

C. Consideration of the Advisory Fees and the Cost of the Services
and Profits to be Realized by BlackRock and its Affiliates from their
Relationship with the Funds: In evaluating the management fees and
expenses that each Fund is expected to bear, the Board considered
each Fund’s current management fee structure and each Fund’s expense
ratios in absolute terms as well as relative to the fees and expense
ratios of its applicable Peers. The Board, among other things, reviewed
comparisons of each Fund’s gross management fees before and after
any applicable reimbursements and fee waivers and total expense ratios
before and after any applicable waivers with those of applicable Peers.
The Board also reviewed a narrative analysis of the Peer rankings pre-
pared by Lipper and summarized by BlackRock at the request of the
Board. This summary placed the Peer rankings into context by analyzing
various factors that affect these comparisons.

The Board noted that the Funds paid contractual management fees
lower than or equal to the median contractual fees paid by their
respective Peers. This comparison was made without giving effect to
any expense reimbursements or fee waivers.

The Board also compared the management fees charged and services
provided by the Advisors to closed-end funds in general versus other
types of clients (such as open-end investment companies and separa-
tely managed institutional accounts) in similar investment categories.
The Board noted certain differences in services provided and costs
incurred by the Advisor with respect to closed-end funds compared to
these other types of clients and the reasons for such differences.

In connection with the Board’s consideration of the fees and expense
information, the Board reviewed the considerable investment manage-
ment experience of the Advisors and considered the high level of invest-
ment management, administrative and other services provided by the
Advisors. In light of these factors and the other facts and circumstances
applicable to each Fund, the Board concluded that the fees paid and
level of expenses incurred by each Fund under its Agreements support a
conclusion that each Fund’s Agreements should be renewed.

D. Profitability of BlackRock: The Board also considered BlackRock’s
profitability in conjunction with its review of fees. The Board reviewed
BlackRock’s profitability with respect to the Fund Complex and other
fund complexes managed by the Advisors. In reviewing profitability, the
Board recognized that one of the most difficult issues in determining
profitability is establishing a method of allocating expenses. The Board
also reviewed BlackRock’s assumptions and methodology of allocating
expenses, noting the inherent limitations in allocating costs among
various advisory products. The Board also recognized that individual
fund or product line profitability of other advisors is generally not
publicly available.

The Board recognized that profitability may be affected by numerous
factors including, among other things, the types of funds managed,
expense allocations and business mix, and therefore comparability of
profitability is somewhat limited. Nevertheless, to the extent available,
the Board considered BlackRock’s operating margin compared to the
operating margin estimated by BlackRock for a leading investment man-
agement firm whose operations consist primarily of advising closed-end
funds. The comparison indicated that BlackRock’s operating margin was
approximately the same as the operating margin of such firm.

In evaluating the reasonableness of the Advisors’ compensation, the
Board also considered any other revenues paid to the Advisors, including
partial reimbursements paid to the Advisors for certain non-investment
advisory services, if applicable. The Board noted that these payments
were less than the Advisors’ costs for providing these services. The Board
also considered indirect benefits (such as soft dollar arrangements)
that the Advisors and their affiliates are expected to receive, which are
attributable to their management of the Fund.

The Board concluded that BlackRock’s profitability, in light of all the
other facts and circumstances applicable to each Fund, supports a
conclusion that each Fund’s Agreements should be renewed.

E. Economies of Scale: In reviewing each Fund’s fees and expenses,
the Board examined the potential benefits of economies of scale, and
whether any economies of scale should be reflected in the Fund’s fee
structure, for example through the use of breakpoints for the Fund or the
Fund Complex. In this regard, the Board reviewed information provided
by BlackRock, noting that most closed-end fund complexes do not have
fund-level breakpoints because closed-end funds generally do not expe-
rience substantial growth after their initial public offering and each fund
is managed independently consistent with its own investment objectives.
The Board noted that only three closed-end funds in the Fund Complex
have breakpoints in their fee structures. Information provided by Lipper
also revealed that only one closed-end fund complex used a complex-
level breakpoint structure. The Board found, based on its review of
comparable funds, that each Fund’s management fee is appropriate
in light of the scale of the respective Fund.

32 ANNUAL REPORT

JULY 31, 2008

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded)

F. Other Factors: In evaluating fees, the Board also considered indirect
benefits or profits the Advisors or their affiliates may receive as a result
of their relationships with the Funds (“fall-out benefits”). The Directors,
including the Independent Directors, considered the intangible benefits
that accrue to the Advisors and their affiliates by virtue of their relation-
ships with the Funds, including potential benefits accruing to the
Advisors and their affiliates as a result of participating in offerings of
the Funds’ shares, potentially stronger relationships with members of the
broker-dealer community, increased name recognition of the Advisors
and their affiliates, enhanced sales of other investment funds and prod-
ucts sponsored by the Advisors and their affiliates and increased assets
under management which may increase the benefits realized by the
Advisors from soft dollar arrangements with broker-dealers. The Board
also considered the unquantifiable nature of these potential benefits.

Conclusion with Respect to the Agreements

In reviewing the Agreements, the Directors did not identify any single
factor discussed above as all-important or controlling and different
Directors may have attributed different weights to the various factors
considered. The Directors, including the Independent Directors, unani-
mously determined that each of the factors described above, in light of
all the other factors and all of the facts and circumstances applicable
to each respective Fund, was acceptable for each Fund and supported
the Directors’ conclusion that the terms of each Agreement were fair
and reasonable, that each Fund’s fees are reasonable in light of the
services provided to the respective Fund and that each Agreement
should be approved.

JULY 31, 2008

Additional Information

Dividend Policy

The Funds’ dividend policy is to distribute all or a portion of their net
investment income to their shareholders on a monthly basis. In order to
provide shareholders with a more stable level of dividend distributions,
the Funds 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 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
Statement of Assets and Liabilities, which comprieses part of the financial
information included in these reports.

Fund Certification

The Funds are listed for trading on the New York Stock Exchange (“NYSE”)
and have filed with the NYSE their annual chief executive officer certifica-
tion regarding compliance with the NYSE’s listing standards. Each Fund

filed with the Securities and Exchange Commission (“SEC”) the certifica-
tion of their chief executive officer and chief financial officer required by
section 302 of the Sabanes-Oxley Act.

Availability of Quarterly Schedule of Investments

The Funds file their complete schedule of portfolio holdings with the SEC
for the first and third quarters of each fiscal year on Form N-Q. The Funds’
Forms N-Q are available on the SEC’s website at http://www.sec.gov and
may also be reviewed and copied at the SEC’s Public Reference Room

in Washington, DC. Information on the operation of the Public Reference
Room may be obtained by calling (800) SEC-0330. The Funds’ Forms
N-Q may also be obtained upon request and without charge by calling
(800) 441-7762.

Electronic Delivery

Electronic copies of most financial reports are available on the Funds’
websites or shareholders can sign up for e-mail notifications of quarterly
statements, annual and semi-annual reports by enrolling in the Funds’
electronic delivery program.

Shareholders Who Hold Accounts with Investment Advisors, Banks
or Brokerages:

Please contact your financial advisor to enroll. Please note that not all
investment advisors, banks or brokerages may offer this service.

ANNUAL REPORT

JULY 31, 2008

Additional Information (continued)

General Information

The Funds do not make available copies of their Statements of Additional
Information because the Funds’ shares are not continuously offered,
which means that the Statements of Additional Information of the Funds
have not been updated after completion of the Funds’ offering and the
information contained in the Funds’ Statements of Additional Information
may have become outdated.

During the period, there were no material changes in the Funds’ invest-
ment objectives or policies or to the Funds’ charters or by-laws that were
not approved by the shareholders or in the principal risk factors associ-
ated with investment in the Funds. There have been no changes in the
persons who are primarily responsible for the day-to-day management of
the Funds’ portfolios.

The Funds will mail only one copy of shareholder documents, including
annual and semi-annual reports and proxy statements, to shareholders
with multiple accounts at the same address. This practice is commonly
called “householding” and it is intended to reduce expenses and elimi-
nate duplicate mailings of shareholder documents. Mailings of your
shareholder documents may be householded indefinitely unless you
instruct us otherwise. If you do not want the mailing of these documents
to be combined with those for other members of your household, please
contact the Funds at (800) 441-7762.

Quarterly performance, semi-annual and annual reports and other
information regarding the Funds may be found on BlackRock’s website,
which can be accessed at http://www.blackrock.com. This reference
to BlackRock’s website is intended to allow investors public access to
information regarding the Funds and does not, and is not intended to,
incorporate BlackRock’s website into this report.

Deposit Securities

Effective May 30, 2008, following approval by the Funds’ Boards and the
applicable ratings agencies, the definition of “Deposit Securities” in the
Funds’ Articles Supplementary was amended as follows in order to facili-
tate the redemption of the Funds’ Preferred Stock. The following phrase
was added to the definition of “Deposit Securities” found in the Funds’
Articles Supplementary:

; provided, however, that solely in connection with any redemption of
Preferred Stock the term Deposit Securities shall include (i) any com-
mitted financing pursuant to a credit agreement, reverse repurchase
agreement facility or similar credit arrangement, in each case which
makes available to the Corporation, no later than the day preceding

the applicable redemption date, cash in an amount not less than the
aggregate amount due to Holders by reason of the redemption of
their shares of Preferred Stock on such redemption date; and (ii) cash
amounts due and payable to the Corporation out of a sale of its
securities if such cash amount is not less than the aggregate amount
due to Holders by reason of the redemption of their shares of
Preferred Stock on such redemption date and such sale will be set-
tled not later than the day preceding the applicable redemption date.

Additional Information (concluded)

BlackRock Privacy Principles

BlackRock is committed to maintaining the privacy of its current and
former fund investors and individual clients (collectively, “Clients”) and to
safeguarding their non-public personal information. The following infor-
mation is provided to help you understand what personal information
BlackRock collects, how we protect that information and why in certain
cases we share such information with select parties.

If you are located in a jurisdiction where specific laws, rules or regulations
require BlackRock to provide you with additional or different privacy-
related rights beyond what is set forth below, then BlackRock will comply
with those specific laws, rules or regulations.

BlackRock obtains or verifies personal non-public information from and
about you from different sources, including the following: (i) information
we receive from you or, if applicable, your financial intermediary, on appli-
cations, forms or other documents; (ii) information about your transac-
tions with us, our affiliates, or others; (iii) information we receive from a
consumer reporting agency; and (iv) from visits to our websites.

BlackRock does not sell or disclose to non-affiliated third parties any non-
public personal information about its Clients, except as permitted by law
or as is necessary to respond to regulatory requests or to service Client
accounts. These non-affiliated third parties are required to protect the
confidentiality and security of this information and to use it only for its
intended purpose.

We may share information with our affiliates to service your account or to
provide you with information about other BlackRock products or services
that may be of interest to you. In addition, BlackRock restricts access to
non-public personal information about its Clients to those BlackRock
employees with a legitimate business need for the information. BlackRock
maintains physical, electronic and procedural safeguards that are
designed to protect the non-public personal information of its Clients,
including procedures relating to the proper storage and disposal of
such information.

Proxy Voting Policy

The Boards of the Funds have delegated the voting of proxies for Fund
securities to the Advisor pursuant to the Advisor’s proxy voting guidelines.
Under these guidelines, the Advisor will vote proxies related to Fund secu-
rities in the best interests of each Fund and its stockholders. From time
to time, a vote may present a conflict between the interests of the Funds’
stockholders, on the one hand, and those of the Advisor, or any affiliated
person of the Funds or the Advisor, on the other. In such event, provided
that the Advisor’s Equity Investment Policy Oversight Committee, or a sub-
committee thereof (the “Committee”) is aware of the real or potential
conflict or material non-routine matter and if the Committee does not

reasonably believe it is able to follow its general voting guidelines (or if
the particular proxy matter is not addressed in the guidelines) and vote
impartially, the Committee may retain an independent fiduciary to advise
the Committee on how to vote or to cast votes on behalf of the Advisor’s
clients. If the Advisor 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 Advisor’s Portfolio Management Group and/or the Advisor’s Legal and
Compliance Department and concluding that the vote is in its client’s
best interest notwithstanding the conflict.

ANNUAL REPORT

JULY 31, 2008

This report is transmitted to shareholders only. This is not a prospec-
tus. Past performance results shown in this report should not be
considered a representation of future performance. The Funds have
leveraged their Common Stock, which creates risks for Common
Stock shareholders, including the likelihood of greater volatility of
net asset value and market price of shares of the Common Stock,
and the risk that fluctuations in the short-term dividend rates of the
Preferred Stock, currently set at the maximum reset rate as a result
of failed auctions, may affect the yield to Common Stock share-
holders. Statements and other information herein are as dated
and are subject to change.

A description of the policies and procedures that the Funds use to
determine how to vote proxies relating to portfolio securities is
available (1) without charge, upon request, by calling toll-free
(800) 441-7762; (2) at www.blackrock.com; and (3) on the Securities
and Exchange Commission’s website at http://www.sec.gov. Infor-
mation about how the Funds voted proxies relating to securities
held in the Funds’ portfolios during the most recent 12-month
period ended June 30 is available upon request and without
charge (1) at www.blackrock.com or by calling (800) 441-7762

Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end
of the period covered by this report, applicable to the registrant’s principal executive officer,
principal financial officer and principal accounting officer, or persons performing similar
functions. During the period covered by this report, there have been no amendments to or
waivers granted under the code of ethics. A copy of the code of ethics is available without
charge at www.blackrock.com.

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:
Kent Dixon (term began effective November 1, 2007)
Frank J. Fabozzi (term began effective November 1, 2007)
James T. Flynn (term began effective November 1, 2007)
Ronald W. Forbes (term ended effective November 1, 2007)
W. Carl Kester (term began effective November 1, 2007)
Karen P. Robards (term began effective November 1, 2007)
Robert S. Salomon, Jr. (term began effective November 1, 2007)
Richard R. West (term ended 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 a member of the audit committee 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.

3 The nature of the services include a review of compliance procedures and attestation thereto.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:
The registrant’s audit committee (the “Committee”) has adopted policies and
procedures with regard to the pre-approval of services. Audit, audit-related and tax
compliance services provided to the registrant on an annual basis require specific pre-
approval by the Committee. The Committee also must approve other non-audit services
provided to the registrant and those non-audit services provided to the registrant’s affiliated
service providers that relate directly to the operations and the financial reporting of the
registrant. Certain of these non-audit services that the Committee believes are a) consistent
with the SEC’s auditor independence rules and b) routine and recurring services that will
not impair the independence of the independent accountants may be approved by the
Committee without consideration on a specific case-by-case basis (“general pre-approval”).
The term of any general pre-approval is 12 months from the date of the pre-approval, unless
the Committee provides for a different period. Tax or other non-audit services provided to
the registrant which have a direct impact on the operation or financial reporting of the
registrant will only be deemed pre-approved provided that any individual project does not
exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the
Committee oversees. For this purpose, multiple projects will be aggregated to determine if
they exceed the previously mentioned cost levels.
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. At this meeting, an analysis of such services is presented to the Committee
for ratification. The Committee may delegate to one or more of its members the authority to
approve the provision of and fees for any specific engagement of permitted non-audit
services, including services exceeding pre-approved cost levels.

(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

(g) Affiliates’ Aggregate Non-Audit Fees:

(h) The registrant’s audit committee has considered and determined that the provision of
non-audit services that were rendered to the 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 maintaining the principal
accountant’s independence.

(a) The registrant’s Schedule of Investments is included as part of the Report to
Stockholders filed under Item 1 of this form.
(b) Not Applicable due to no such divestments during the semi-annual period covered since
the previous Form N-CSR filing.

Item 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management
Investment Companies – The Board of Directors of the Fund has delegated the voting of
proxies for the Fund securities to the Investment Adviser pursuant to the Investment
Adviser’s proxy voting guidelines. Under these guidelines, the Investment Adviser will vote
proxies related to Fund securities in the best interests of the Fund and its stockholders. From
time to time, a vote may present a conflict between the interests of the Fund’s stockholders,
on the one hand, and those of the Investment Adviser, or any affiliated person of the Fund or
the Investment Adviser, on the other. In such event, provided that the Investment Adviser’s
Equity Investment Policy Oversight Committee, or a sub-committee thereof (the
“Committee”) is aware of the real or potential conflict or material non-routine matter and if
the Committee does not reasonably believe it is able to follow its general voting guidelines
(or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the
Committee may retain an independent fiduciary to advise the Committee on how to vote or
to cast votes on behalf of the Investment Adviser’s clients. If the Investment Adviser
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 Investment Adviser’s Portfolio Management Group and/or the
Investment Adviser’s Legal and Compliance Department and concluding that the vote cast
is in its client’s best interest notwithstanding the conflict. A copy of the Fund’s Proxy
Voting Policy and Procedures are attached as Exhibit 99.PROXYPOL. Information on how
the Fund voted proxies relating to portfolio securities during the most recent 12-month
period ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the
SEC’s website at http://www.sec.gov.

(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 for 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 or 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 a
fund. In this regard, it should be noted that a portfolio manager may currently manage
certain accounts that are subject to performance fees. In addition, a portfolio manager may
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 July 31, 2008:

Portfolio Manager Compensation Overview

BlackRock’s financial arrangements with its portfolio managers, its competitive
compensation and its career path emphasis at all levels reflect the value senior management
places on key resources. Compensation may include a variety of components and may vary
from year to year based on a number of factors. The principal components of compensation

include a base salary, a performance-based discretionary bonus, participation in various
benefits programs and one or more of the incentive compensation programs established by
BlackRock such as its Long-Term Retention and Incentive Plan.

Base compensation. Generally, portfolio managers receive base compensation based on
their seniority and/or their position with the firm. Senior portfolio managers who perform
additional management functions within the portfolio management group or within
BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation
Discretionary incentive compensation is a function of several components: the performance
of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock,
the investment performance, including risk-adjusted returns, of the firm’s assets under
management or supervision by that portfolio manager relative to predetermined
benchmarks, and the individual’s seniority, role within the portfolio management team,
teamwork and contribution to the overall performance of these portfolios and BlackRock.
In most cases, including for the portfolio managers of the Fund, these benchmarks are the
same as the benchmark or benchmarks against which the performance of the Fund or other
accounts managed by the portfolio managers are measured. BlackRock’s Chief Investment
Officers determine the benchmarks against which the performance of funds and other
accounts managed by each portfolio manager is compared and the period of time over which
performance is evaluated. With respect to the portfolio managers, such benchmarks for the
Fund include a combination of market-based indices (e.g. Lehman Brothers Municipal Bond
Index), certain customized indices and certain fund industry peer groups.

BlackRock’s Chief Investment Officers make a subjective determination with respect to the
portfolio managers’ compensation based on the performance of the funds and other accounts
managed by each portfolio manager relative to the various benchmarks noted above.
Performance is measured on both a pre-tax and after-tax basis over various time periods
including 1, 3, 5 and 10-year periods, as applicable.

Distribution of Discretionary Incentive Compensation
Discretionary incentive compensation is distributed to portfolio managers in a combination
of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of
years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in
BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base
salary, represents more than 60% of total compensation for the portfolio managers. Paying
a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a
given year “at risk” based on BlackRock’s ability to sustain and improve its performance
over future periods.

Long-Term Retention and Incentive Plan (“LTIP”) — The LTIP is a long-term
incentive plan that seeks to reward certain key employees. Beginning in 2006, awards are
granted under the LTIP in the form of BlackRock, Inc. restricted stock units that, if properly
vested and subject to the attainment of certain performance goals, will be settled in
BlackRock, Inc. common stock. Each portfolio manager except Mr. Stuebe has received
awards under the LTIP.

Deferred Compensation Program — A portion of the compensation paid to eligible
BlackRock employees may be voluntarily deferred into an account that tracks the
performance of certain of the firm’s investment products. Each participant in the deferred

compensation program is permitted to allocate his deferred amounts among the various
investment options. Each portfolio manager has participated in the deferred compensation
program.

Other compensation benefits. In addition to base compensation and discretionary
incentive compensation, portfolio managers may be eligible to receive or participate in one
or more of the following:

Incentive Savings Plans — 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. BlackRock contributions follow the
investment direction set by participants for their own contributions or, absent employee
investment direction, are invested into a balanced portfolio. 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 July 31, 2008, none of Messrs. Jaeckel,
O’Connor or Stuebe beneficially owned any stock issued by the Fund.

Item 9 – Purchases of Equity Securities by Closed-End Management Investment Company and
