MuniHoldings
Insured Fund, Inc.


www.mlim.ml.com


MuniHoldings Insured Fund, Inc. seeks to provide shareholders with
current income exempt from Federal income taxes by investing
primarily in a portfolio of long-term, investment-grade municipal
obligations the interest on which, in the opinion of bond counsel to
the issuer, is exempt from Federal income taxes. Under normal
circumstances, the Fund invests at least 80% of its total assets in
municipal bonds that are covered by insurance.

This report, including the financial information herein, is
transmitted to shareholders of MuniHoldings Insured Fund, Inc. for
their information. It is not a prospectus. Past performance results
shown in this report should not be considered a representation of
future performance. The Fund has leveraged its Common Stock and
intends to remain leveraged by issuing Preferred Stock to provide
the Common Stock shareholders with a potentially higher rate of
return. Leverage creates risks for Common Stock shareholders,
including the likelihood of greater volatility of net asset value
and market price of shares of the Common Stock, and the risk that
fluctuations in the short-term dividend rates of the Preferred Stock
may affect the yield to Common Stock shareholders. Statements and
other information herein are as dated and are subject to change.

MUNIHOLDINGS INSURED FUND, INC.


The Benefits and
Risks of
Leveraging


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

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issue 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 on the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange), may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities.



Swap
Agreements


The Fund may also 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.




MuniHoldings Insured Fund, Inc., April 30, 2003


DEAR SHAREHOLDER


For the year ended April 30, 2003, the Common Stock of MuniHoldings
Insured Fund, Inc. had a net annualized yield of 5.86%, based on a
year-end per share net asset value of $14.48 and $.848 per share
income dividends. Over the same period, the total investment return
on the Fund's Common Stock was +12.04%, based on a change in per
share net asset value from $13.78 to $14.48, and assuming
reinvestment of $.845 per share income dividends.

For the six-month period ended April 30, 2003, the total investment
return on the Fund's Common Stock was +7.24%, based on a change in
per share net asset value from $13.95 to $14.48, and assuming
reinvestment of $.428 per share ordinary income dividends.

For the six-month period ended April 30, 2003, the Fund's Auction
Market Preferred Stock had an average yield of 1.13% for Series A
and 1.10% for Series B.

For a description of the Fund's total investment return based on a
change in the per share market value (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 the Financial Statements included in 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
Fund's market value can vary significantly from total investment
return based on changes in the Fund's net asset value.


The Municipal Market Environment
During the six-month period ended April 30, 2003, amid considerable
weekly and monthly volatility, long-term fixed income interest rates
generally declined. Geopolitical tensions and volatile equity
valuations continued to overshadow economic fundamentals as they
have for most of the last 12 months. Reacting to the strong U.S.
equity rally that began last October, fixed income bond yields
remained under pressure in November 2002, as U.S. equity markets
continued to strengthen. During November, the Standard & Poor's 500
(S&P 500) Index rose an additional 5.50%. Equity prices were
supported by further signs of U.S. economic recovery, especially
improving labor market activity. In late November, third-quarter
2002 U.S. gross domestic product growth was 4%, well above the
second-quarter 2002 rate of 1.30%. Financial conditions were also
strengthened by a larger-than-expected reduction in short-term
interest rates by the Federal Reserve Board in early November. The
Federal Funds target rate was lowered 50 basis points (0.50%) to
1.25%, its lowest level since the 1960s. This action by the Federal
Reserve Board was largely viewed as being taken to bolster the
sputtering U.S. economic recovery. Rebounding U.S. equity markets
and the prospects for a more substantial U.S. economic recovery
pushed long-term U.S. Treasury yield levels to 5.10% by late
November.

However, into early 2003, softer equity prices and renewed investor
concerns about U.S. military action against Iraq and North Korea
again pushed bond prices higher. Reacting to disappointing holiday
sales and corporate managements' attempts to scale back analysts'
expectation of future earnings, the S&P 500 Index declined more than
10% from December 2002 to February 2003. Fearing an eventual U.S./
Iraq military confrontation in 2003, investors again sought the
safety of U.S. Treasury obligations and the prices of fixed income
issues rose. By the end of February 2003, U.S. Treasury bond yields
had declined approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. Once direct U.S.
military action against Iraq began, bond yields quickly rose. Prior
uncertainty surrounding the Iraqi situation was obviously removed
and early U.S. military successes fostered the hope that the
conflict would be quickly and positively concluded. Concurrently,
the S&P 400 Index rose over 6% as investors, in part, sold fixed
income issues to purchase equities in anticipation of a strong U.S.
economic recovery once the Iraqi conflict was resolved. By mid-
March, U.S. Treasury bond yields again rose to above 5%. However, as
there was growing sentiment that hostilities may not be resolved in
a matter of weeks, U.S. Treasury bond yields again declined to end
the month at 4.81%.

For the six months ended April 30, 2003, long-term U.S. Treasury
bond yields ratcheted back to near 5% by mid-April, as U.S. equity
markets continued to improve and the safe-haven premium U.S.
Treasury issues had commanded prior to the beginning of the Iraqi
conflict continued to be withdrawn. However, with the quick positive
resolution of the Iraqi war, investors quickly resumed their focus
on the fragile U.S. economic recovery. Business activity in the
United States has remained sluggish, especially job creation.
Investors have also been concerned that the recent SARS outbreak
would have a material, negative impact on world economic conditions,
especially in China and Japan. First quarter 2003 U.S. gross
domestic product was released in late April initially estimating
U.S. economic activity to be growing at 1.60%, well below many
analysts' assessments. These factors, as well as the possibility
that the Federal Reserve Board could again lower short-term interest
rates to encourage more robust U.S. economic growth, pushed bond
prices higher during the last two weeks of the period. By April 30,
2003, long-term U.S. Treasury bond yields had declined to almost
4.75%. Over the past six months, long-term U.S. bond yields fell
more than 20 basis points.

For the six months ended April 30, 2003, long-term tax-exempt bond
yields also fell modestly. Yield volatility was reduced relative to
that seen in U.S. Treasury issues, as municipal bond prices were
much less sensitive to worldwide geopolitical pressures on a daily
and weekly basis. Tax-exempt bond yields generally followed their
taxable counterparts higher, responding to a more positive U.S.
fixed income environment and continued slow economic growth. After
rising approximately 10 basis points in November 2002 to 5.30%,
municipal bond yields generally declined through February 2003. At
February 28, 2003, long-term tax-exempt revenue bond yields, as
measured by the Bond Buyer Revenue Bond Index, fell to approximately
5.05%. However, similar to U.S. Treasury bond yields, once military
action began in Iraq, municipal bond yields rose sharply to nearly
5.20% before declining to approximately 5.10% by the end of April.
Over the past six months, long-term tax-exempt bond yields fell
approximately 11 basis points, slightly less than U.S. Treasury
obligations.

A number of factors have combined to generate consistently strong
demand for municipal bonds throughout the six-month period ended
April 30, 2003. Generally weak U.S. equity markets have supported
continued positive demand for tax-exempt products as investors have
sought the relative security of fixed income issues. Also, with tax-
exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer
maturity issues rather than remain in cash reserves. Additionally,
investors received approximately $30 billion in January 2003 from
bond maturities, coupon income and proceeds from early redemptions.
However, these positive demand factors were not totally able to
offset the increase in tax-exempt new-issue supply, preventing more
significant declines in tax-exempt bond yields. This modest
underperformance has served to make municipal bonds a particularly
attractive purchase relative to their taxable counterparts.
Throughout most of the yield curve, municipal bonds have been able
to be purchased at yields near or exceeding those of comparable
Treasury issues. Compared to their recent historical averages of
82% - 88% of U.S. Treasury yields, municipal bond yield ratios in
their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures
have resulted in reduced economic activity and consumer confidence.
It is important to note that, despite all the recent negative
factors impeding the growth of U.S. businesses, the U.S. economy
still grew at an approximate 2.50% rate for all of 2002, twice that
of 2001. Similar expansion is expected for early 2003. Lower oil
prices, reduced geopolitical uncertainties, increased Federal
spending for defense, and a likely Federal tax cut are all factors
which should promote stronger economic growth later this year.
However, it is questionable to expect that business and investor
confidence can be so quickly restored as to trigger dramatic,
explosive U.S. economic growth and engender associated, large-scale
interest rate increases. The resumption of solid economic growth is
likely to be a gradual process accompanied by equally graduated
increases in bond yields. Moderate economic growth, especially
within a context of negligible inflationary pressures, should not
greatly endanger the positive fixed income environments tax-exempt
products currently enjoy.



MuniHoldings Insured Fund, Inc., April 30, 2003


Portfolio Strategy
During the past six months, our principal portfolio strategy has
been to maintain the slightly defensive market stance adopted early
in 2002 while maintaining a competitive tax-exempt yield. We focused
on positioning the Fund into sectors demonstrating value and
reducing exposure in sectors that seemed expensive by historical
standards. Because of heavy issuance, California insured bonds were
trading at a deep discount compared to the rest of the municipal
market. We took advantage of this by overweighting the California
sector during the fourth quarter of 2002. Our strategy proved
successful as supply declined during the first quarter of 2003,
enabling the Fund to perform well relative to its peers. We also
continued to pursue extending out the yield curve. The municipal
yield curve has become extremely steep during the past year, with
the ten-year area of the curve being the most volatile. We sold
bonds maturing inside of ten years and used the proceeds to purchase
bonds with maturities greater than 20 years. This enabled the Fund
to increase its average accrual yield, while reducing its
volatility. Looking forward, we will maintain the Fund's defensive
structure to limit portfolio asset volatility and retain its
competitive yield. We will wait until the domestic economy begins a
recovery before positioning the Fund in a more defensive stance.

During the period, the Fund's borrowing costs remained in the
1% - 1.50% range, with interest rates presently near 1%. These very
attractive funding levels, in combination with the steep tax-exempt
yield curve, have continued to generate significant income benefits
to the Fund's Common Stock shareholders. We do not expect any
material reduction in the Fund's borrowing costs in 2003 as no
additional easings by the Federal Reserve Board are anticipated. We
expect the Fund's short-term borrowing costs to remain at current
attractive levels for the coming months. However, should the spread
between short-term and long-term interest rates narrow, the benefits
of leverage will decline, and as a result, reduce the yield on the
Fund's Common Stock. (For a more complete explanation of the
benefits and risks of leveraging, see page 1 of this report to
shareholders.)

We appreciate your investment in MuniHoldings Insured Fund, Inc.,

MuniHoldings Insured Fund, Inc., April 30, 2003


NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniHoldings Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. The Fund's financial statements are
prepared in conformity with accounting principles generally accepted
in the United States of America, which may require the use of
management accruals and estimates. The Fund's Common Stock is listed
on the New York Stock Exchange under the symbol MUS. The following
is a summary of significant accounting policies followed by the
Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. 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 over-the-counter-market, valuation is the last
asked price (options written) or the last bid price (options
purchased). Securities with remaining maturities of sixty days or
less are valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of
the Fund and to hedge, or protect, its exposure to interest rate
movement 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--The Fund may purchase or sell
financial futures contracts and options on such futures contracts.
Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

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

Written and purchased options are non-income producing investments.

* Forward interest rate swaps--The Fund is authorized to enter
into forward interest rate swaps. In a forward interest rate swap,
the Fund and the counterparty agree to pay or receive interest on
a specified notional contract amount, commencing on a specified
future effective date, unless terminated earlier. The value of the
agreement is determind by quoted fair values received daily by the
Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of
the agreement.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

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

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

(f) Reclassification--Accounting principles generally accepted in
the United States of America require that certain components of
net assets be adjusted to reflect permanent differences between
financial and tax reporting. Accordingly, the current year's
permanent book/tax difference of $18,946 has been reclassified
between undistributed net investment income and accumulated net
realized capital losses. This reclassification has no effect on net
assets or net asset value per share.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect, wholly-owned

limited partner.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of .55% of
the Fund's average weekly net assets, including proceeds from the
issuance of Preferred Stock. For the year ended April 30, 2003, FAM
earned fees of $1,732,685, of which $171,866 was waived. For the
year ended April 30, 2003, FAM reimbursed the Fund in the amount of
$9,310.

For the year ended April 30, 2003, the Fund reimbursed FAM $12,262
for certain accounting services.

directors of FAM, PSI, and/or ML & Co.

4. Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of stock,

were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of stock
without approval of holders of Common Stock.

Preferred Stock of the Fund, with a par value of $.10 per share and
a liquidation preference of $25,000 per share plus accrued and

follows: Series A, 1.15% and Series B, 1.25%.

                                                      =============


*On April 30, 2003, the Fund had a net capital loss carryforward of
$24,817,934, of which $15,234,021 expires in 2008 and $9,583,913
expires in 2009. 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.

MANAGED DIVIDEND POLICY (unaudited)

order to provide shareholders with a more consistent yield to the
current trading price of shares of Common Stock of the Fund, the
Fund may at times pay out less than the entire amount of net
investment income earned in any particular month and may at times in
any particular month pay out such accumulated but undistributed
income in addition to net investment income earned in that month. As
a result, the dividends paid by the Fund for any particular month
may be more or less than the amount of net investment income earned
by the Fund during such month. The Fund's current accumulated but
undistributed net investment income, if any, is disclosed in the
Statement of Net Assets, which comprises part of the financial
information included in this report.

AUTOMATIC DIVIDEND REINVESTMENT PLAN (unaudited)


The following description of the Fund's Automatic Dividend
Reinvestment Plan (the "Plan") is sent to you annually as required
by Federal securities laws.

Pursuant to the Fund's Plan, unless a holder of Common Stock
otherwise elects, all dividend and capital gains distributions
will be automatically reinvested by The Bank of New York (the "Plan
Agent"), as agent for shareholders in administering the Plan, in
additional shares of Common Stock of the Fund. Holders of Common
Stock who elect not to participate in the Plan will receive
all distributions in cash paid by check mailed directly to the
shareholder of record (or, if the shares are held in street or
other nominee name then to such nominee) by The Bank of New York,
as dividend paying agent. Such participants may elect not to
participate in the Plan and to receive all distributions of
dividends and capital gains in cash by sending written instructions
to The Bank of New York, as dividend paying agent, at the address
set forth below. Participation in the Plan is completely voluntary
and may be terminated or resumed at any time without penalty by
written notice if received by the Plan Agent not less than ten days
prior to any dividend record date; otherwise such termination will
be effective with respect to any subsequently declared dividend or
distribution.

Whenever the Fund declares an income dividend or capital gains
distribution (collectively referred to as "dividends") payable
either in shares or in cash, non-participants in the Plan will
receive cash and participants in the Plan will receive the
equivalent in shares of Common Stock. The shares will be acquired
by the Plan Agent for the participant's account, depending upon the
circumstances described below, either (i) through receipt of
additional unissued but authorized shares of Common Stock from the
Fund ("newly issued shares") or (ii) by purchase of outstanding
shares of Common Stock on the open market ("open-market purchases")
on the New York Stock Exchange or elsewhere. If on the payment date
for the dividend, the net asset value per share of the Common Stock
is equal to or less than the market price per share of the Common
Stock plus estimated brokerage commissions (such conditions being
referred to herein as "market premium"), the Plan Agent will invest
the dividend amount in newly issued shares on behalf of the
participant. The number of newly issued shares of Common Stock to be
credited to the participant's account will be determined by dividing
the dollar amount of the dividend by the net asset value per share
on the date the shares are issued, provided that the maximum
discount from the then current market price per share on the date of
issuance may not exceed 5%. If on the dividend payment date the net
asset value per share is greater than the market value (such
condition being referred to herein as "market discount"), the Plan
Agent will invest the dividend amount in shares acquired on behalf
of the participant in open-market purchases.

In the event of a market discount on the dividend payment date, the
Plan Agent will have until the last business day before the next
date on which the shares trade on an "ex-dividend" basis or in no
event more than 30 days after the dividend payment date (the "last
purchase date") to invest the dividend amount in shares acquired in
open-market purchases. It is contemplated that the Fund will pay
monthly income dividends. Therefore, the period during which open-
market purchases can be made will exist only from the payment date
on the dividend through the date before the next "ex-dividend" date,
which typically will be approximately ten days. If, before the Plan
Agent has completed its open-market purchases, the market price of
a share of Common Stock exceeds the net asset value per share,
the average per share purchase price paid by the Plan Agent may
exceed the net asset value of the Fund's shares, resulting in the
acquisitions of fewer shares than if the dividend had been paid in
newly issued shares on the dividend payment date. Because of the
foregoing difficulty with respect to open-market purchases, the
Plan provides that if the Plan Agent is unable to invest the full
dividend amount in open-market purchases during the purchase period
or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market
purchases and will invest the uninvested portion of the dividend
amount in newly issued shares at the close of business on the last
purchase date determined by dividing the uninvested portion of the
dividend by the net asset value per share.

The Plan Agent maintains all shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account,
including information needed by shareholders for tax records. Shares
in the account of each Plan participant will be held by the Plan
Agent in non-certificated form in the name of the participant, and
each shareholder's proxy will include those shares purchased or
received pursuant to the Plan. The Plan Agent will forward all proxy
solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.

In the case of shareholders such as banks, brokers or nominees which
hold shares of others who are the beneficial owners, the Plan Agent
will administer the Plan on the basis of the number of shares
certified from time to time by the record shareholders as
representing the total amount registered in the record shareholder's
name and held for the account of beneficial owners who are to
participate in the Plan.

There will be no brokerage charges with respect to shares issued
directly by the Fund as a result of dividends or capital gains
distributions payable either in shares or in cash. However, each
participant will pay a pro rata share of brokerage commissions
incurred with respect to the Plan Agent's open-market purchases in
connection with the reinvestment of dividends.

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.

Shareholders participating in the Plan may receive benefits not
available to shareholders not participating in the Plan. If the
market price plus commissions of the Fund's shares is above the net
asset value, participants in the Plan will receive shares of the
Fund at less than they could otherwise purchase them and will have
shares with a cash value greater than the value of any cash
distribution they would have received on their shares. If the market
price plus commissions is below the net asset value, participants
will receive distributions in shares with a net asset value greater
than the value of any cash distribution they would have received on
their shares. However, there may be insufficient shares available in
the market to make distributions in shares at prices below the net
asset value. Also, since the Fund does not redeem shares, the price
on resale may be more or less than the net asset value.

The value of shares acquired pursuant to the Plan will generally be
excluded from gross income to the extent that the cash amount
reinvested would be excluded from gross income. If, when the Fund's
shares are trading at a premium over net asset value, the Fund
issues shares pursuant to the Plan that have a greater fair market
value than the amount of cash reinvested, it is possible that all or
a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable
distribution. If the discount is viewed as a taxable distribution,
it is also possible that the taxable character of this discount
would be allocable to all the shareholders, including shareholders
who do not participate in the Plan. Thus, shareholders who do not
