A Letter From the President


Dear Shareholder


By now, you have probably heard of the important changes unfolding at Merrill
Lynch Investment Managers ("MLIM"). We have been communicating with
shareholders, via letters like this and in a detailed proxy mailing, about
MLIM's impending union with another highly regarded investment manager -
BlackRock, Inc. ("BlackRock"). This transaction marks the next chapter in
MLIM's growth story and, we believe, will be a benefit to our investors.

MLIM, a division of Merrill Lynch with over $583 billion in assets under
management, is a leading investment manager offering more than 100 investment
strategies in vehicles ranging from mutual funds to institutional portfolios.
BlackRock, with $464.1 billion in assets under management, is one of the
largest publicly traded investment management firms in the United States
managing assets on behalf of institutional and individual investors worldwide
through a variety of equity, fixed income, liquidity and alternative investment
products. At the completion of the transaction, which is expected around the
end of the third quarter of 2006, the resultant firm will be a top-10
investment manager worldwide with over $1 trillion in assets under management.*

The combined company, to be known as BlackRock, will provide a wide selection
of high-quality investment solutions across a range of asset classes and
investment styles. The organization will have over 4,500 employees in 18
countries and a major presence in key markets worldwide. MLIM and BlackRock
possess complementary capabilities that together create a well-rounded
organization uniting some of the finest money managers in the industry. The
firms share similar values and beliefs - each strives for excellence in all
areas, and both make investment performance their single most important
mission. As such, our combination only reinforces our commitment to
shareholders.

Most of MLIM's investment products - including mutual funds, separately
managed accounts, annuities and variable insurance funds - eventually will
carry the "BlackRock" name. This will be reflected in newspaper and online
information sources beginning in October. Your account statements will reflect
the BlackRock name beginning with the October month-end reporting period.
Unless otherwise communicated via a proxy statement, your funds will maintain
the same investment objectives that they do today. Importantly, the MLIM/
BlackRock union will not affect your brokerage account or your relationship
with your financial advisor. If you are a client of Merrill Lynch, you will
remain a client of Merrill Lynch.

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



Sincerely,



(Robert C. Doll, Jr.)
Robert C. Doll, Jr.

A Discussion With Your Funds' Portfolio Managers


The Funds adopted a neutral stance on interest rates as the Federal Reserve
Board approached a pause in its prolonged interest rate tightening campaign.


Describe the recent market environment relative to municipal bonds.

During the past 12 months, long-term bond yields rose sharply while their
prices, which move in the opposite direction, declined. The drop in bond
prices largely reflects investors' focus on solid economic growth. Despite a
decline in gross domestic product growth between the first and second quarters
of 2006, U.S. economic activity so far this year has outpaced the 3.2% annual
growth rate posted in 2005. Rising commodity prices also have stoked
inflationary fears, further weighing on bond prices.

The Federal Reserve Board (the Fed) continued to raise short-term interest
rates at each of its meetings during the past year, bringing the federal funds
rate to 5.25%. Consequently, the yield curve continued to flatten, with short-
term interest rates rising more than longer-term interest rates. Overall,
30-year U.S. Treasury bond yields rose 60 basis points (.60%) during the
12-month period to 5.07%, while 10-year U.S. Treasury note yields rose 71 basis
points to 4.99%. Municipal bond yields also rose in recent months, although
the tax-exempt market's strong technical position provided significant price
support. This allowed municipal bond prices to decline less than their taxable
counterparts. As measured by Municipal Market Data, yields on AAA-rated issues
maturing in 30 years rose just 12 basis points to 4.47%, and yields on AAA-
rated issues maturing in 10 years rose 33 basis points to 3.99%.

The rise in yields prompted a revival in investor demand for municipal bonds.
The increased demand also was triggered by seasonal factors that served to
generate large cash flows into investor accounts. Investors received more than
$40 billion in June and July from coupon income and the proceeds from bond
maturities and early redemptions. Consequently, municipal bond fund flows have
continued to be supportive. As reported by the Investment Company Institute,
open-end tax-exempt bond funds received net new cash inflows of over $6.5
billion in the first six months of 2006, compared to $2.5 billion during the
same period in 2005.

Also contributing to the outperformance of the municipal bond market has been
declines in new issuance. During the past six months, more than $189 billion
in new long-term tax-exempt bonds was underwritten, a decline of 14% compared
to the same period a year earlier. Recent declines in issuance have largely
been the result of a 57% drop in refunding activity so far this year. Rising
bond yields have made the refinancing of existing higher-couponed debt issues
increasingly problematic, as the potential economic savings have rapidly
diminished. In addition, the improved fiscal condition of many state and local
governments has resulted in lower borrowing trends, with many new municipal
capital projects being financed from existing budget surpluses. The declines
in issuance have led many analysts to lower their annual issuance forecasts to
the $300 billion - $325 billion range. Lower annual issuance would further
solidify the tax-exempt market's already positive technical position.

Looking ahead, municipal market fundamentals are likely to remain favorable,
leading us to expect the tax-exempt market to perform at least as well as
comparable U.S. Treasury issues. Attractive yield ratios have continued to
draw both retail and institutional investors to the municipal market. Based on
this, and the prospect for reduced annual issuance in 2006, we believe the
municipal market should continue to perform well in the coming months.


MuniHoldings Fund II, Inc.

How did the Fund perform during the fiscal year?

For the 12-month period ended July 31, 2006, the Common Stock of MuniHoldings
Fund II, Inc. had net annualized yields of 6.00% and 6.30%, based on a year-
end per share net asset value of $14.82 and a per share market price of
$14.12, respectively, and $.889 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +4.89%,
based on a change in per share net asset value from $15.03 to $14.82, and
assuming reinvestment of all distributions.

The Fund's total return, based on net asset value, exceeded the +3.52% average
return of the Lipper General Municipal Debt Funds (Leveraged) category for the
12-month period. (Funds in this Lipper category invest primarily in municipal
debt issues rated in the top four credit-rating categories. These funds can be
leveraged via use of debt, preferred equity and/or reverse repurchase
agreements.)



ANNUAL REPORTS                                                    JULY 31, 2006



Fund performance during the year benefited from the continued contraction of
credit spreads in the municipal market. This had a favorable impact on our
positions in tax-backed and corporate-related debt, where we have a significant
concentration, as well as our healthcare-related holdings and land-secured
deals. The greatest contribution to performance came from the Fund's positions
in airline-related debt. While this sector lagged in the first six months,
airlines rallied strongly in the latter half of the period due to considerable
spread tightening. This proved beneficial to some of our larger holdings in
Continental Airlines, Inc., American Airlines Inc. and US Airways (formerly
America West Airlines). Also contributing to performance was strong
appreciation in the portfolio's holdings in the bonds of Pocahontas Parkway
Association, a toll road in Virginia that was constructed within the past few
years. The bonds increased in value as the roadway was sold to a private
entity resulting in the subsequent defeasance of the project's outstanding
debt. (When bonds are defeased, it typically means that the securities are
retired at their first call date, enabling the bonds to appreciate
significantly.) Finally, our yield curve strategy also proved advantageous.
For most of the period, the Fund was overweight in bonds with maturities
greater than 20 years. This benefited performance as the yield curve flattened
and longer-term bonds outperformed short-term issues.

For the six-month period ended July 31, 2006, the total investment return on
the Fund's Common Stock was +2.82%, based on a change in per share net asset
value from $14.84 to $14.82, and assuming reinvestment of all distributions.

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


What changes were made to the portfolio during the period?

Broadly speaking, we moved the portfolio from a slightly defensive stance to a
more neutral posture as the Fed appeared to be approaching a pause in its
interest rate-hiking campaign. Although both the Treasury and the municipal
yield curves continued to flatten during the past 12 months, the move was not
nearly as dramatic as we have seen in prior periods. Notably, the municipal
curve retained a positive slope, particularly relative to the Treasury curve,
which actually inverted early in 2006. This contributed to the municipal
market's and the Fund's positive performance.

The Fund maintained its focus on refundable, essential service securities from
high demand states. The lack of new-issue supply and increased demand for
municipal bonds has caused spreads to narrow in all sectors of the municipal
market. We took advantage of these tight spreads to move the Fund's exposure
to spread product to neutral while increasing its position in bonds exempt
from tax in specialty states. We believe this strategy should prove beneficial
with any shift in the demand/supply imbalance in both the high yield sector
and the broader municipal market.

For the six months ended July 31, 2006, the average yield for the Fund's
Auction Market Preferred Stock (AMPS) was 3.35% for Series A and 3.13% for
Series B. The Fed raised the short-term interest rate target 200 basis points
during the 12-month period, and this continued to affect the Fund's borrowing
costs. On August 8, 2006, the Fed opted to pause in its interest rate-hiking
campaign and is expected to be "data dependent" in determining monetary policy
going forward. As such, we would expect additional increases in the Fund's
cost of funds to be more limited. Despite the interest rate increases during
the period, the tax-exempt yield curve maintained a positive slope, allowing
us to borrow at a lower rate than where we invest. This continued to generate
an income benefit to the holders of Common Stock from the leveraging of
Preferred Stock. However, should the spread between short-term and long-term
interest rates narrow, the benefits of leveraging will decline and, as a
result, reduce the yield on the Fund's Common Stock. At the end of the period,
the Fund's leverage amount, due to AMPS, was 34.40% of total net assets,
before the deduction of Preferred Stock. (For a more complete explanation of
the benefits and risks of leveraging, see page 8 of this report to
shareholders.)



ANNUAL REPORTS                                                    JULY 31, 2006



A Discussion With Your Funds' Portfolio Managers (concluded)


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

We remain focused on generating an attractive level of tax-exempt income for
our shareholders. The Fund ended the period fully invested and with an overall
neutral market posture. After 17 consecutive interest rate hikes, the Fed
paused in its monetary tightening program in early August and has indicated
that it will look at the economic data when determining monetary policy going
forward. Because global economies and certain pockets of the U.S. economy
continue to show solid growth with higher headline inflationary figures, we
believe that it still may be early to become too aggressive in our investment
strategy. In our view, a neutral posture is prudent in the current environment
and should provide for competitive performance.


MuniHoldings New Jersey Insured Fund, Inc.

Describe conditions in the State of New Jersey.

Jon Corzine claimed victory in the state's November gubernatorial election
and, upon beginning his term in January, immediately faced the challenges of
the fiscal year 2007 budget. By the end of the second quarter, New Jersey had
failed to adopt a balanced budget for the new fiscal year (beginning July 1).
The point of contention was Governor Corzine's proposal to raise the state
sales tax to 7% from 6%. As a result, the governor ordered a shutdown of non-
essential state services for several days in early July until an agreement
could be reached with the State Assembly. In the past, deficit financing had
served as one alternative to deadlocked budget negotiations; however, the New
Jersey Supreme Court had recently prohibited the state from borrowing in order
to balance budgets. Nevertheless, throughout the shutdown, the rating agencies
maintained the state's ratings and outlook.

Ultimately, a $31 billion budget was adopted for fiscal year 2007. The 1%
sales tax increase was implemented and is expected to generate roughly
$1.2 billion in income. As part of the agreement with the Assembly, one-half
of the new sales tax receipts will be allocated to property tax rebates. The
budget also includes tax increases and surcharges on various items, such as
cigarettes, car rentals and luxury goods. Other key components in reducing the
projected $4.5 billion budget gap included approximately $2 billion in spending
reductions and freezes. The budget keeps state aid to municipalities and school
districts essentially flat for another year and, as such, local property taxes
are likely to increase. The budget also contributes $1.1 billion into the state
pension system, exceeding the entire amount allocated in the past 10 years.
The adopted budget significantly reduces reliance on onetime revenues and,
therefore, is more structurally balanced than the state's last several
budgets - a positive from a credit rating perspective.

New Jersey has a high and growing debt burden compared to similarly rated
states. In addition, the state recently started a five-year, $6 billion debt
financing program for transportation projects, and funding of billions of
dollars in court-mandated school construction projects is yet to be
determined.


How did the Fund perform during the fiscal year?

For the 12-month period ended July 31, 2006, the Common Stock of MuniHoldings
New Jersey Insured Fund, Inc. had net annualized yields of 5.74% and 5.71%,
based on a year-end per share net asset value of $14.91 and a per share market
price of $14.98, respectively, and $.856 per share income dividends. Over the
same period, the total investment return on the Fund's Common Stock was
+1.09%, based on a change in per share net asset value from $15.62 to $14.91,
and assuming reinvestment of all distributions.

The Fund's total return, based on net asset value, trailed the +2.70% average
return of the Lipper New Jersey Municipal Debt Funds category for the 12-month
period. (Funds in this Lipper category limit their investment to those
securities exempt from taxation in New Jersey or a city in New Jersey.
Notably, the Fund was disadvantaged relative to many of its peers by its
conservative investment parameters. Specifically, the Fund is limited in its
ability to invest in lower-quality issues, which outperformed during the year
as credit spreads (versus higher-quality issues of comparable maturity)
tightened dramatically. Per its investment parameters, at least 80% of the
portfolio was invested in AAA-rated, insured bonds throughout the year.

Another factor that weighed on the Fund's performance was the fact that a
number of seasoned holdings with higher coupons were called by their issuers.
Given our limited ability to buy lower-rated issues and a decline in new-issue
supply during the period, particularly in the early months of 2006, it was
especially difficult to compensate for the income lost to calls.



ANNUAL REPORTS                                                    JULY 31, 2006



For the six-month period ended July 31, 2006, the total investment return on
the Fund's Common Stock was +.53%, based on a change in per share net asset
value from $15.24 to $14.91, and assuming reinvestment of all distributions.

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


What changes were made to the portfolio during the period?

For most of the fiscal year, the portfolio was positioned for the yield curve
flattening we had anticipated, and we saw little need to make significant
changes as the Fed tirelessly increased interest rates and the long end of the
curve outperformed. In more recent months, as the Fed approached the end of
its monetary tightening campaign and the curve appeared ready to resteepen, we
began to see opportunities in the intermediate maturity range. This is an area
that suffered most as rates rose and, in a resteepening scenario, could be
positioned for strong relative performance. To take advantage, in the final
three months of the fiscal year, we focused mainly on trimming some of the
short-term investments in the portfolio, particularly bonds that are callable
or likely to be called within the next year or two. With the proceeds, we
invested in bonds in the 10-year - 15-year portion of the curve. Despite a
decline in new municipal bond issuance, we had little trouble finding
opportunities in this maturity range. Throughout the year, we continued to
maintain a high-quality portfolio consistent with our conservative investment
parameters. Approximately 83% - 84% of the Fund's net assets was invested in
insured municipal paper.

For the six-month period ended July 31, 2006, the Fund's Auction Market
Preferred Stock (AMPS) had average yields as follows: Series A, 3.07%; Series
B, 2.99%; Series C, 3.00%; Series D, 2.96%; and Series E, 2.94%. The Fed raised
the short-term interest rate target 200 basis points during the 12-month
period, and this continued to affect the Fund's borrowing costs. On August 8,
2006, the Fed opted to pause in its interest rate-hiking campaign and is
expected to be "data dependent" in determining monetary policy going forward.
As such, we would expect additional increases in the Fund's cost of funds to
be more limited. Despite the interest rate increases during the period, the
tax-exempt yield curve maintained a positive slope, allowing us to borrow at
a lower rate than where we invest. This continued to generate an income benefit
to the holders of Common Stock from the leveraging of Preferred Stock. However,
should the spread between short-term and long-term interest rates narrow, the
benefits of leveraging will decline and, as a result, reduce the yield on the
Fund's Common Stock. At the end of the period, the Fund's leverage amount, due
to AMPS, was 39.07% of total net assets, before the deduction of Preferred
Stock. (For a more complete explanation of the benefits and risks of
leveraging, see page 8 of this report to shareholders.)


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

At period-end, the Fund remained relatively neutral with respect to interest
rate risk. As mentioned earlier, our yield curve outlook changed in the final
months of the period on speculation that the Fed may be close to ending its
monetary tightening program. That pause in policy tightening came in early
August, affirming our revised yield curve strategy. Still, there remains
uncertainty as to whether the Fed will pursue additional interest rate hikes
down the road, as Chairman Bernanke and the governors have indicated that they
will let the economic and inflationary data guide their interest rate
decisions. Having said that, the consensus expectation is that economic growth
will continue to moderate, thereby alleviating inflationary pressures and
discouraging the Fed from pursuing further interest rate hikes. As such, we
will continue to seek out value closer to the middle of the municipal yield
curve, while maintaining a high-quality portfolio.

The Benefits and Risks of Leveraging


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

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

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

As a part of its investment strategy, the Funds may invest in certain
securities whose potential income return is inversely related to changes in a
floating interest rate ("inverse floaters"). In general, income on inverse
floaters will decrease when short-term interest rates increase and increase
when short-term interest rates decrease. Investments in inverse floaters may
be characterized as derivative securities and may subject the Funds to the
risks of reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of providing
investment leverage and, as a result, the market value of such securities will
generally be more volatile than that of fixed rate, tax-exempt securities. To
the extent the Funds invest in inverse floaters, the market value of each
Fund's portfolio and the net asset value of each Fund's shares may also be
more volatile than if the Funds did not invest in these securities. As of July
31, 2006, the percentages of MuniHoldings Fund II, Inc. and MuniHoldings New
Jersey Insured Fund, Inc.'s total net assets invested in inverse floaters were
8.26% and 4.97%, respectively, before the deduction of Preferred Stock.

Notes to Financial Statements


1. Significant Accounting Policies:
MuniHoldings Fund II, Inc. and MuniHoldings New Jersey Insured Fund, Inc. (the
"Funds" or individually as the "Fund") are registered under the Investment
Company Act of 1940, as amended, as non-diversified, closed-end management
investment companies. The Funds' financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may
require the use of management accruals and estimates. Actual results may
differ from these estimates. The Funds determine and make available for
publication the net asset value of their Common Stock on a daily basis. The
Funds' Common Stock shares are listed on the New York Stock Exchange under the
symbols MUH and MUJ, respectively. The following is a summary of significant
accounting policies followed by the Funds.

(a) Valuation of investments--Municipal bonds are traded primarily in the over-
the-counter ("OTC") markets and are valued at the last available bid price in
the OTC market or on the basis of values as obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Funds under the general
direction of the Board of Directors. Such valuations and procedures are
reviewed periodically by the Board of Directors of the Funds. Financial
futures contracts and options thereon, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges. Options
written or purchased are valued at the last sale price in the case of exchange-
traded options. In the case of options traded in the OTC market, valuation is
the last asked price (options written) or the last bid price (options
purchased). Swap agreements are valued by quoted fair values received daily by
the Funds' pricing service. Short-term investments with a remaining maturity
of 60 days or less are valued at amortized cost, which approximates market
value, under which method the investment is valued at cost and any premium or
discount is amortized on a straight line basis to maturity. Valuation of other
short-term investment vehicles is generally based on the net asset value of
the underlying investment vehicle or amortized cost. Investments in open-end
investment companies are valued at their net asset value each business day.
Securities and other assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Funds.

(b) Derivative financial instruments--Each Fund may engage in various
portfolio investment strategies both to increase the return of the Fund and to
hedge, or protect, its exposure to interest rate movements and movements in
the securities markets. Losses may arise due to changes in the value of the
contract or if the counterparty does not perform under the contract.

* Financial futures contracts--Each Fund may purchase or sell financial
futures contracts and options on such futures contracts. Futures contracts are
contracts for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund deposits
and maintains as collateral such initial margin as required by the exchange on
which the transaction is effected. Pursuant to the contract, the Fund agrees
to receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known as
variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

* Options--Each Fund may write covered call options and purchase call and put
options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked-to-market to reflect the
current market value of the option written. When a security is purchased or
sold through an exercise of an option, the related premium paid (or received)
is added to (or deducted from) the basis of the security acquired or deducted
from (or added to) the proceeds of the security sold. When an option expires
(or the Fund enters into a closing transaction), the Fund realizes a gain or
loss on the option to the extent of the premiums received or paid (or gain or
loss to the extent the cost of the closing transaction exceeds the premium
paid or received).

Written and purchased options are non-income producing investments.

Notes to Financial Statements (continued)


* Forward interest rate swaps--Each Fund may enter into swap agreements, which
are OTC contracts in which the Fund and a counterparty agree to make periodic
net payments on a specified notional amount. The net payments can be made for
a set period of time or may be triggered by a predetermined credit event. The
net periodic payments may be based on a fixed or variable interest rate; the
change in market value of a specified security, basket of securities, or
index; or the return generated by a security. These periodic payments received
or made by the Fund are recorded in the accompanying Statement of Operations
as realized gains or losses, respectively. Gains or losses are also realized
upon termination of the swap agreements. Swaps are marked-to-market daily and
changes in value are recorded as unrealized appreciation (depreciation). Risks
include changes in the returns of the underlying instruments, failure of the
counterparties to perform under the contracts' terms and the possible lack of
liquidity with respect to the swap agreements.

(c) 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.

(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Funds amortize all
premiums and discounts on debt securities.

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

(f) Recent accounting pronouncement--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48") entitled
"Accounting for Uncertainty in Income Taxes - an interpretation of FASB
Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax
position must meet in connection with accounting for uncertainties in income
tax positions taken or expected to be taken by an entity including mutual
funds before being measured and recognized in the financial statements. FIN 48
is effective for fiscal years beginning after December 15, 2006. The Funds
will adopt FIN 48 during the fiscal 2008 year and the impact on the Funds'
financial statements, if any, is currently being assessed.


2. Investment Advisory Agreement and Transactions with Affiliates:
Each Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services,
Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co.,
Inc. ("ML & Co."), which is the limited partner.

FAM is responsible for the management of each Fund's portfolio and provides
the necessary personnel, facilities, equipment and certain other services
necessary to the operations of the Fund. For such services, each Fund pays a
monthly fee at an annual rate of .55% of the Fund's average weekly net assets,
including proceeds from the issuance of Preferred Stock for the year ended
July 31, 2006. The Investment Adviser has agreed to reimburse its management
fee by the amount of management fees each Fund pays to FAM indirectly through
its investment described below:


                                                          Reimbursement

MuniHoldings New Jersey        CMA New Jersey
  Insured Fund, Inc.           Municipal Money Fund             $19,874


In addition, for MuniHoldings New Jersey Insured Fund, Inc., the Investment
Adviser has agreed to reimburse its management fee based on the proceeds of
Preferred Stock that exceeds 35% of the Fund's total net assets. For the year
ended July 31, 2006, FAM earned fees of $2,877,148, of which $167,935 was
waived.

For the year ended July 31, 2006, MuniHoldings Fund II, Inc. and MuniHoldings
New Jersey Insured Fund, Inc. reimbursed FAM $5,584 and $11,597, respectively,
for certain accounting services.

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

Notes to Financial Statements (continued)


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

On August 15, 2006, shareholders of each Fund approved a new Investment
Advisory Agreement with BlackRock Advisors, Inc., a subsidiary of BlackRock,
Inc., as well as a contingent sub-advisory agreement with BlackRock Advisors,
Inc. The new advisory agreement will become effective upon the closing of the
BlackRock transaction described above and the investment advisory fees will be
unchanged.

 * On July 31, 2006, the Fund had a net capital loss carryforward of
   $15,495,993, of which $2,509,399 expires in 2008, $12,107,981
   expires in 2009, $689,205 expires in 2010 and $189,408 expires
   in 2011. This amount will be available to offset like amounts of any
   future taxable gains.

** The difference between book-basis and tax-basis net unrealized
   gains is attributable primarily to the tax deferral of losses on wash
   sales and the difference between book and tax amortization
   methods for premiums and discounts on fixed income securities.

 * On July 31, 2006, the Fund had a net capital loss carryforward of
   $24,258,827, of which $24,022,933 expires in 2009 and $235,894
   expires in 2011. This amount will be available to offset like amounts
   of any future taxable gains.

** The difference between book-basis and tax-basis net unrealized
   gains is attributable primarily to the tax deferral of losses on
   straddles and the difference between book and tax amortization
   methods for premiums and discounts on fixed income securities.

Report of Independent Registered Public Accounting Firm


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

We have audited the accompanying statements of net assets, including the
schedules of investments, of MuniHoldings Fund II, Inc. and of MuniHoldings
New Jersey Insured Fund, Inc. (the "Funds") as of July 31, 2006, and the
related statements of operations, statements of changes in net assets, and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The respective financial statements
of each of the Funds for the year ended July 31, 2005 and the financial
highlights of each of the Funds for each of the four years in the period ended
July 31, 2005 were audited by other auditors whose report, dated September 12,
2005, expressed an unqualified opinion on those financial statements and
financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Funds are not required to have, nor were we engaged to
perform, an audit of their internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as
a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. Our procedures included confirmation of securities owned as of
July 31, 2006, by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the respective financial
positions of MuniHoldings Fund II, Inc. and of MuniHoldings New Jersey Insured
Fund, Inc. as of July 31, 2006, the results of their operations, the changes
in their net assets, and their financial highlights for the year then ended,
in conformity with U.S. generally accepted accounting principles.

ANNUAL REPORTS                                                    JULY 31, 2006



Automatic Dividend Reinvestment Plan


How the Plan Works--The Funds offer a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by each Fund are
automatically reinvested in additional shares of Common Stock of each Fund.
The Plan is administered on behalf of the shareholders by The Bank of New York
(the "Plan Agent"). Under the Plan, whenever the Funds declare a dividend,
participants in the Plan will receive the equivalent in shares of Common Stock
of each Fund. The Plan Agent will acquire the shares for the participant's
account either (i) through receipt of additional unissued but authorized
shares of each Fund ("newly issued shares") or (ii) by purchase of outstanding
shares of Common Stock on the open market on the New York Stock Exchange or
elsewhere. If, on the dividend payment date, each Fund's net asset value per
share is equal to or less than the market price per share plus estimated
brokerage commissions (a condition often referred to as a "market premium"),
the Plan Agent will invest the dividend amount in newly issued shares. If the
Funds' net asset value per share is greater than the market price per share (a
condition often referred to as a "market discount"), the Plan 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 voluntary and may be terminated or resumed at any
time without penalty by writing to the Plan Agent.

Benefits of the Plan--The Plan provides an easy, convenient way for
shareholders to make additional, regular investments in the Funds. The Plan
promotes a long-term strategy of investing at a lower cost. All shares
acquired pursuant to the Plan receive voting rights. In addition, if the
market price plus commissions of each Fund's shares is above the net asset
value, participants in the Plan will receive shares of the Funds for less than
they could otherwise purchase them and with a cash value greater than the
value of any cash distribution they would have received. However, there may
not be enough shares available in the market to make distributions in shares
at prices below the net asset value. Also, since each Fund does not redeem
shares, the price on resale may be more or less than the net asset value.

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

Tax Implications--The automatic reinvestment of dividends and distributions
will not relieve participants of any federal, state or local income tax that
may be payable (or required to be withheld) on such dividends. Therefore,
income and capital gains may still be realized even though shareholders do not
receive cash. Participation in the Plan generally will not effect the tax-
exempt status of exempt interest dividends paid by the Fund. If, when the
Funds' shares are trading at a market premium, the Funds issue shares pursuant
to the Plan that have a greater fair market value than the amount of cash
reinvested, it is possible that all or a portion of the discount from the
market value (which may not exceed 5% of the fair market value of each Fund's
shares) could be viewed as a taxable distribution. If the discount is viewed
as a taxable distribution, it is also possible that the taxable character of
this discount would be allocable to all the shareholders, including
shareholders who do not participate in the Plan. Thus, shareholders who do not
participate in the Plan might be required to report as ordinary income a
portion of their distributions equal to their allocable share of the discount.

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

Disclosure of Investment Advisory Agreement


Activities and Composition of the Boards of Directors

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


Investment Advisory Agreement--Matters Considered by the Boards

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

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

Each Board believes that the Investment Adviser is one of the most experienced
global asset management firms and considers the overall services provided by
the Investment Adviser to be of high quality. Each Board also believes that
the Investment Adviser is financially sound and well managed and notes that
the Investment Adviser is affiliated with one of America's largest financial
firms. Each Board works closely with the Investment Adviser in overseeing the
Investment Adviser's efforts to achieve good performance. As part of this
effort, each Board discusses portfolio manager effectiveness and, when
performance is not satisfactory, discusses with the Investment Adviser taking
steps such as changing investment personnel.


Annual Consideration of Approval by the Boards of Directors

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


Certain Specific Renewal Data

In connection with the most recent renewal of each Fund's Investment Advisory
Agreement in February 2006, the independent directors' and Boards' review
included the following:



ANNUAL REPORTS                                                    JULY 31, 2006



Disclosure of Investment Advisory Agreement (concluded)


Services Provided by the Investment Adviser--Each Board reviewed the nature,
extent and quality of services provided by the Investment Adviser, including
the investment advisory services and the resulting performance of the Fund.
Each Board focused primarily on the Investment Adviser's investment advisory
services and the Fund's investment performance. Each Board compared Fund
performance - both including and excluding the effects of the Fund's fees and
expenses - to the performance of a comparable group of funds and the
performance of a relevant index or combination of indexes. The Board
considered the small number of funds classified by Lipper as comparable funds
to MuniHoldings New Jersey Insured Fund, Inc. While each Board reviews
performance data at least quarterly, consistent with the Investment Adviser's
investment goals, the Boards attach more importance to performance over
relatively long periods of time, typically three to five years.

Relative to closed-end leveraged general municipal debt funds deemed
comparable by the Investment Adviser, the Board noted that for the periods
ended November 30, 2005, MuniHoldings Fund II, Inc.'s performance for the one-,
three- and five-year periods ranked in the first quintile. The Board also
reviewed MuniHoldings Fund II, Inc.'s performance based on annualized total
return and annualized yield. The Board noted that with respect to both total
return and yield the Fund ranked in the first quintile for the years ended
November 30, 2005, 2004 and 2003; with respect to total return in the third
quintile for the year ended November 30, 2002 and the first quintile for the
year ended November 30, 2001; and with respect to yield in the second quintile
for the years ended November 30, 2002 and 2001. The Board noted the lack of
any significant number of comparable closed-end leveraged New Jersey municipal
debt funds, but did note that relative to the three comparable funds
identified MuniHoldings New Jersey Insured Fund, Inc.'s performance for the
periods ended November 30, 2005 ranked third out of three funds for the one-
year period, second out of three funds for the three-year period and first out
of two funds for the five-year period. The Board also noted that MuniHoldings
New Jersey Insured Fund, Inc.'s performance based on annualized yields ranked
second out of three funds for the years ended November 30, 2005 and 2003,
third out of three funds for the year ended November 30, 2004, and second out
of two funds for the years ended November 30, 2002 and 2001. Each Board
concluded that the Fund's performance supported the continuation of the
Investment Advisory Agreement.

The Investment Adviser's Personnel and Investment Process--Each Board reviewed
the Fund's investment objectives and strategies. Each Board discusses with
senior management of the Investment Adviser responsible for investment
operations and the senior management of the Investment Adviser's municipal
investing group the strategies being used to achieve the stated objectives.
Among other things, each Board considers the size, education and experience of
the Investment Adviser's investment staff, its use of technology, and the
Investment Adviser's approach to training and retaining portfolio managers and
other research, advisory and management personnel. Each Board also reviews the
Investment Adviser's compensation policies and practices with respect to the
Fund's portfolio manager. Each Board also considered the experience of the
Fund's portfolio manager. It was noted that Mr. DiMella, the portfolio manager
for MuniHoldings Fund II, Inc., has more than 13 years' experience in
portfolio management and Mr. Jaeckel, the portfolio manager for MuniHoldings
New Jersey Insured Fund, Inc., has more than 15 years' experience. The Boards
considered that the Investment Adviser and its investment staff have extensive
experience in analyzing and managing the types of investments used by the
Funds. The Boards concluded that the Funds benefit from that experience.

Management Fees and Other Expenses--Each Board reviews the Fund's contractual
management fee rate and actual management fee rate as a percentage of total
assets at common asset levels - the actual rate includes advisory and
administrative service fees and the effects of any fee waivers - compared to
the other funds in its Lipper category. It also compares the Fund's total
expenses to those of other comparable funds. Each Board considered the
services provided to and the fees charged by the Investment Adviser to retail
closed-end funds with similar investment mandates. The Boards noted that the
investment advisory fees charged to each of the Funds was equal to or slightly
more than the fees charged to other retail closed-end funds of the Investment
Adviser. With respect to MuniHoldings Fund II, Inc., the Board noted that the
contractual and actual management fee rates and total expense ratio were below
the median fees charged by comparable funds, as determined by Lipper. With
respect to MuniHoldings New Jersey Insured Fund, Inc., the Board noted that
the contractual management fee rate was equal to and the actual management fee
rate was higher than the median fee charged by comparable funds, as determined
by Lipper, while the actual total expense ratio was slightly lower than the
median charged by such comparable funds. The Boards concluded that each Fund's
management fee rate (including fee waivers) and overall expense ratio are
reasonable compared to those of other comparable funds.



ANNUAL REPORTS                                                    JULY 31, 2006



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

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


Conclusion

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

Disclosure of New Investment Advisory Agreement


New BlackRock Investment Advisory Agreements--Matters Considered by the Boards

In connection with the Transaction between Merrill Lynch and BlackRock, each
Fund's Board of Directors considered a new investment advisory agreement (each
a "New Investment Advisory Agreement") between the Fund and BlackRock
Advisors, Inc. or its successor ("BlackRock Advisors"). Each Fund's New
Investment Advisory Agreement has been approved by the Fund's shareholders and
is expected to become effective upon the closing of the Transaction in the
third quarter of 2006.

The Boards discussed the New Investment Advisory Agreements at telephonic and
in-person meetings held during April and May 2006. Each Board, including the
independent directors, approved the applicable New Investment Advisory
Agreement at a meeting held on May 12, 2006.

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

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

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

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

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

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

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

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

*  that Merrill Lynch and BlackRock would derive benefits from the
   Transaction and that, as a result, they have a different financial
   interest in the matters that were being considered than do Fund
   shareholders.

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

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



ANNUAL REPORTS                                                    JULY 31, 2006



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

*  the compliance policies and procedures of BlackRock Advisors;

*  the terms and conditions of each New Investment Advisory Agreement,
   including the fact that neither Fund's schedule of total advisory fees
   will increase by virtue of the Fund's New Investment Advisory Agreement,
   but will remain the same;

*  that in February 2006, each Fund's Board performed a full annual review of
   the investment advisory agreement currently in effect for the Fund (each a
   "Current Investment Advisory Agreement") as required by the 1940 Act and
   determined that the Investment Adviser has the capabilities, resources and
   personnel necessary to provide the advisory and administrative services
   currently provided to the Fund; and that the advisory and/or management
   fees to be paid by the Fund, taking into account any applicable agreed-
   upon fee waivers and breakpoints, represented reasonable compensation to
   the Investment Adviser in light of the services to be provided, the
   expected costs to the Investment Adviser of providing those services,
   potential economies of scale, the fees and other expenses paid by similar
   funds (including information provided by Lipper Inc. ["Lipper"]), and such
   other matters as the directors considered relevant in the exercise of
   their reasonable judgment; and

*  that Merrill Lynch agreed to pay all expenses of each Fund in connection
   with the Board's consideration of the New Investment Advisory Agreement
   and related agreements and all costs of shareholder approval of the New
   Investment Advisory Agreement and as a result the Fund would bear no costs
   in obtaining shareholder approval of the New Investment Advisory
   Agreement.

Certain of these considerations are discussed in more detail below.

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

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

In their deliberations, each Fund's directors considered information received
in connection with their recent continuation of the Fund's Current Investment
Advisory Agreement, in addition to information provided by BlackRock and
BlackRock Advisors in connection with their evaluation of the terms and
conditions of the Fund's New Investment Advisory Agreement. Neither Fund's
directors identified any particular information that was all-important or
controlling, and each director attributed different weights to the various
factors. The directors of each Fund, including a majority of the independent
directors, concluded that the terms of the Fund's New Investment Advisory
Agreement are appropriate, that the fees to be paid are reasonable in light of
the services to be provided to the Fund, and that the New Investment Advisory
Agreement should be approved and recommended to Fund shareholders.

Disclosure of New Investment Advisory Agreement (continued)


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

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

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

Each Fund's directors were advised that, as a result of Merrill Lynch's equity
interest in BlackRock after the Transaction, the Fund will continue to be
subject to restrictions concerning certain transactions involving Merrill
Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer
acting as principal) absent revised or new regulatory relief. Each Fund's
directors were advised that a revision of existing regulatory relief with
respect to these restrictions was being sought from the Securities and
Exchange Commission and were advised of the possibility of receipt of such
revised regulatory relief. There can be no assurance that such relief will be
obtained.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, each Fund's
directors determined that the nature and quality of services to be provided to
the Fund under the New Investment Advisory Agreement were expected to be as
good as or better than that provided under the Fund's Current Investment
Advisory Agreement. It was noted, however, that it is expected that there will
be changes in personnel following the Transaction and the combination of the
operations of the Investment Adviser and its affiliates with those of
BlackRock. Each Fund's directors noted that if current portfolio managers or
other personnel cease to be available, the Board would consider all available
options, which could include seeking the investment advisory or other services
of BlackRock affiliates. Accordingly, each Fund's directors concluded that,
overall, they were satisfied at the present time with assurances from
BlackRock and BlackRock Advisors as to the expected nature, extent and quality
of the services to be provided to the Fund under its New Investment Advisory
Agreement.

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



ANNUAL REPORTS                                                    JULY 31, 2006



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

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

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

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

Fall-Out Benefits--In evaluating the fall-out benefits to be received by
BlackRock Advisors under the New Investment Advisory Agreement, each Fund's
directors considered whether the Transaction would have an impact on the fall-
out benefits received by the Investment Adviser by virtue of the Current
Investment Advisory Agreement. Based on their review of the materials
provided, including materials received in connection with their most recent
approval of the Current Investment Advisory Agreement, and their discussions
with management of the Investment Adviser and BlackRock, each Fund's directors
determined that those benefits could include increased ability for BlackRock
to distribute shares of its funds and other investment products. The directors
noted that any fall-out benefits were difficult to quantify with certainty at
this time, and indicated that they would continue to evaluate them going
forward.

Disclosure of New Investment Advisory Agreement (concluded)


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

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


Contingent BlackRock Subadvisory Agreements--Matters Considered by the Boards

At the telephonic and in-person meetings held during April and May 2006 at
which each Board of Directors discussed and approved the New Investment
Advisory Agreement, the Board, including the independent directors, also
considered and approved a contingent subadvisory agreement (each a "Contingent
Subadvisory Agreement") between the Investment Adviser and BlackRock Advisors
(the "BlackRock Subadviser"). Each Fund's Contingent Subadvisory Agreement is
intended to ensure that the Fund operates with efficient portfolio management
services until the closing of the Transaction, in the event that the Fund's
Board deems it necessary and in the best interests of the Fund and its
shareholders that the BlackRock Subadviser assist in managing the operations
of the Fund during the interim period until the closing of the Transaction.
Each Fund's Contingent Subadvisory Agreement would take effect only upon
recommendation from the Investment Adviser and upon subsequent approval of the
Fund's Board in the period up to the closing of the Transaction. The
effectiveness of each Fund's Contingent Subadvisory Agreement, therefore, is
contingent on further Board approval. Pursuant to each Contingent Subadvisory
Agreement, the BlackRock Subadviser would receive a monthly fee from the
Investment Adviser equal to 50% of the advisory fee received by the Investment
Adviser. The Investment Adviser would pay the BlackRock Subadviser out of its
own resources. There would be no increase in either Fund's expenses as a
result of the Contingent Subadvisory Agreement.

In making its approval at the May in-person meeting, each Board considered the
Contingent Subadvisory Agreement in conjunction with the New Investment
Advisory Agreement and reviewed the same information and factors discussed
above, and came to the same conclusions. Each Fund's Board also considered in
conjunction with the Contingent Subadvisory Agreement the necessity of
ensuring that the Fund operates with effective management services until the
closing of the Transaction. In reviewing the subadvisory fee rate provided in
each Fund's Contingent Subadvisory Agreement, the Fund's Board took note of
the fact that both the Investment Adviser and the BlackRock Subadviser would
have significant responsibilities under their respective advisory agreements.
The Investment Adviser would remain responsible for oversight of each Fund's
operations and administration and the BlackRock Subadviser would provide
advisory services to the Fund under the Contingent Subadvisory Agreement. Each
Fund's Board also took into account the expected short duration of the term of
any Contingent Subadvisory Agreement and the fact that total advisory fees
paid by the Fund would not increase as a result of the Contingent Subadvisory
Agreement. Under all of the circumstances, each Fund's Board concluded that it
was a reasonable allocation of fees for the BlackRock Subadviser to receive
50% of the advisory fee paid by the Fund to the Investment Adviser.

After the independent directors of each Fund deliberated in executive session,
the Fund's entire Board, including the independent directors, approved the
applicable Contingent Subadvisory Agreement, concluding that the advisory fee
was reasonable in relation to the services provided and that the Contingent
Subadvisory Agreement was in the best interests of the Fund's shareholders.

Swap Agreements


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



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 Net Assets, which comprises part of the financial information
included in these reports.



Change in Funds' Independent Registered Public Acccounting Firm


On August 28, 2006, Ernst & Young llp ("E&Y") resigned as the Independent
Registered Public Accounting Firm of MuniHoldings Fund II, Inc. and
MuniHoldings New Jersey Insured Fund, Inc. (each a "Fund" and collectively the
"Funds").

E&Y's reports on the financial statements of the Funds for the past two fiscal
years did not contain an adverse opinion or a disclaimer of opinion and were
not qualified or modified as to uncertainty, audit scope or accounting
principles.

In connection with its audits for the two most recent fiscal years and through
August 28, 2006 (1) there were no disagreements with E&Y on any matter of
accounting principle or practices, financial statement disclosure or auditing
scope or procedure, whereby such disagreements, if not resolved to the
satisfaction of E&Y, would have caused them to make reference to the subject
matter of the disagreements in connection with their report on the financial
statements for such years; and (2) there have been no reportable events (as
defined in Item 304(a)(1)(v) of Regulation S-K).

The Audit Committee of each of the Funds' Board of Directors approved the
engagement of Deloitte & Touche llp as the Funds' Independent Registered
Public Accounting Firm for the fiscal years ended July 31, 2006.

           similar functions.  A copy of the code of ethics is available
           without charge upon request by calling toll-free 1-800-MER-FUND
           (1-800-637-3863).

Item 3 -   Audit Committee Financial Expert - The registrant's 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: (1)
           Ronald W. Forbes, (2) Richard R. West, and (3) Edward D. Zinbarg.

Item 4 -   Principal Accountant Fees and Services

           Note: The Fund changed auditors effective August, 28, 2006.  Prior
           to that date, Ernst & Young LLP provided services as the Fund's
           independent registered public accountant.

           (a) Audit Fees -         Fiscal Year Ending July 31, 2006 - $28,000
                                    Fiscal Year Ending July 31, 2005 - $32,000

           (b) Audit-Related Fees - Fiscal Year Ending July 31, 2006 - $3,500
                                    Fiscal Year Ending July 31, 2005 - $3,500

           The nature of the services include assurance and related services
           reasonably related to the performance of the audit of financial
           statements not included in Audit Fees.

           (c) Tax Fees -           Fiscal Year Ending July 31, 2006 - $6,000
                                    Fiscal Year Ending July 31, 2005 - $5,700

           The nature of the services include tax compliance, tax advice and

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

               Fiscal Year Ending July 31, 2005 - $7,926,666

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

Item 6 -   Schedule of Investments - Not Applicable

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

           Proxy Voting Policies and Procedures

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

           (iv) Potential Material Conflicts of Interest



           Real, potential or apparent conflicts of interest may arise when a
portfolio manager has day-to-day portfolio management responsibilities with
respect to more than one fund or account, including the following:

           Certain investments may be appropriate for the Fund and also for
other clients advised by the Investment. Adviser and its affiliates, including
other client accounts managed by the Fund's portfolio management team.
Investment decisions for the Fund and other clients are made with a view to
achieving their respective investment objectives and after consideration of
such factors as their current holdings, availability of cash for investment and
the size of their investments generally. Frequently, a particular security may
be bought or sold for only one client or in different amounts and at different
times for more than one but less than all clients. Likewise, because clients of
the Investment Adviser and its affiliates may have differing investment
strategies, a particular security may be bought for one or more clients when
one or more other clients are selling the security. The investment results for
the Fund may differ from the results achieved by other clients of the
Investment Adviser and its affiliates and results among clients may differ. In
addition, purchases or sales of the same security may be made for two or more
clients on the same day. In such event, such transactions will be allocated
among the clients in a manner believed by the Investment Adviser and its
affiliates to be equitable to each. The Investment Adviser will not determine
allocations based on whether it receives a performance based fee from the
client. In some cases, the allocation procedure could have an adverse effect on
the price or amount of the securities purchased or sold by the Fund. Purchase
and sale orders for the Fund may be combined with those of other clients of the
Investment Adviser and its affiliates in the interest of achieving the most
favorable net results to the Fund.

           To the extent that the Fund's portfolio management team has
responsibilities for managing accounts in addition to the Fund, a portfolio
manager will need to divide his time and attention among relevant accounts.

           In some cases, a real, potential or apparent conflict may also arise
where (i) the Investment Adviser may have an incentive, such as a performance
based fee, in managing one account and not with respect to other accounts it
manages or (ii) where a member of the Fund's portfolio management team owns an
interest in one fund or account he or she manages and not another.

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

           Portfolio Manager Compensation

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

           Compensation Program

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

           Base Salary

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

           Performance-Based Compensation

           MLIM believes that the best interests of investors are served by
recruiting and retaining exceptional asset management talent and managing their
compensation within a consistent and disciplined framework that emphasizes pay
for performance in the context of an intensely competitive market for talent.
To that end, MLIM and its affiliates portfolio manager incentive compensation
is based on a formulaic compensation program. MLIM's formulaic portfolio
manager compensation program includes: investment performance relative to a
subset of general closed-end, New Jersey municipal debt funds over 1-, 3- and 5-
year performance periods and a measure of operational efficiency. Portfolio
managers are compensated based on the pre-tax performance of the products they
manage. If a portfolio manager's tenure is less than 5 years, performance
periods will reflect time in position. Portfolio managers are compensated based
on products they manage. A discretionary element of portfolio manager
compensation may include consideration of: financial results, expense control,
profit margins, strategic planning and implementation, quality of client
service, market share, corporate reputation, capital allocation, compliance and
risk control, leadership, workforce diversity, supervision, technology and
innovation. MLIM and its affiliates also consider the extent to which
individuals exemplify and foster ML & Co.'s principles of client focus, respect
for the individual, teamwork, responsible citizenship and integrity. All
factors are considered collectively by MLIM management.

           Cash Bonus

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

           Stock Bonus

           A portion of the dollar value of the total annual performance-based
bonus is paid in restricted shares of ML & Co. stock. Paying a portion of
annual bonuses in stock puts compensation earned by a portfolio manager for a
given year "at risk" based on the company's ability to sustain and improve its
performance over future periods. The ultimate value of stock bonuses is
dependent on future ML & Co. stock price performance. As such, the stock bonus
aligns each portfolio manager's financial interests with those of the ML & Co.
shareholders and encourages a balance between short-term goals and long-term
strategic objectives. Management strongly believes that providing a significant
portion of competitive performance-based compensation in stock is in the best
interests of investors and shareholders. This approach ensures that portfolio
managers participate as shareholders in both the "downside risk" and "upside
opportunity" of the company's performance. Portfolio managers therefore have a
direct incentive to protect ML & Co.'s reputation for integrity.

           Other Compensation Programs

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

           Other Benefits

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

           (a)(4) Beneficial Ownership of Securities. As of July 31, 2006,
                  Mr. Jaeckel does not beneficially own any stock issued by
                  the Fund.
