Risk/Return Summary
    
 
   
This section highlights key information about the PRUDENTIAL UTILITY FUND, INC.,
which we refer to as "the Fund." Additional information follows this summary.
    
 
   
INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGIES
    
   
Our investment objective is TOTAL RETURN through a combination of capital
appreciation and current income. This means we seek investments whose price will
increase as well as pay the Fund dividends and other income. We normally invest
at least 80% of the Fund's total assets in equity-related and debt securities of
utility companies. These include electric, gas, gas pipeline, telephone,
telecommunications, water, cable, airport, seaport and toll road companies. Some
of these securities are issued by foreign companies. While we make every effort
to achieve our objective, we can't guarantee success.
    
 
   
PRINCIPAL RISKS
    
   
Although we try to invest wisely, all investments involve risk. The Fund is
subject to risks of the utility industry because it concentrates its investments
in utility securities. Since the Fund invests in stocks, there is the risk that
the price of particular stocks we own could go down or pay lower-than-expected
dividends. The value of the equity markets or a sector of them could go down.
Stock markets are volatile.
    
   
    Our investments in investment-grade debt securities involve market risk,
too, and credit risk.
    
   
    Some of our investment strategies -- as well as foreign investments that we
may make -- also involve risk. Like any mutual fund, an investment in the Fund
could lose value, and you could lose money. For more detailed information about
the risks associated with the Fund, see "Investment Risks."
    
   
    An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.
    
 
- -------------------------------------------------------------------
   
WE'RE VALUE INVESTORS
    
   
In deciding which stocks to buy, we use what is known as a value investment
style. This means we invest in stocks of companies that we believe are
undervalued given the company's earnings, assets, cash flow and dividends. Using
this approach, we seek reasonable growth with an eye toward minimizing risk. We
consider selling a security if it has increased to the point where we no longer
consider it to be undervalued.

EVALUATING PERFORMANCE
    
   
A number of factors -- including risk -- affect how the Fund performs. The
following bar chart and table show the Fund's performance for each full calendar
year of operation for the last 10 years. They demonstrate the risk of investing
in the Fund and how returns can change. Past performance does not mean that the
Fund will achieve similar results in the future.

EXAMPLE
    
   
This example will help you compare the fees and expenses of the Fund's
different share classes and compare the cost of investing in the Fund with the
cost of investing in other mutual funds.
    
   
    The example assumes that you invest $10,000 in the Fund for the time
periods indicated and then sell all of your shares at the end of those periods.
The example also assumes that your investment has a 5% return each year
and that the Fund's operating expenses remain the same. Although your
actual costs may be higher or lower, based on these assumptions your costs
would be:

How the Fund Invests
    
 
   
INVESTMENT OBJECTIVE AND POLICIES
    
   
The Fund's investment objective is TOTAL RETURN THROUGH A COMBINATION OF CAPITAL
APPRECIATION AND CURRENT INCOME. This means we seek investments whose price will
increase over several years as well as pay the Fund dividends and other income.
While we make every effort to achieve our objective, we can't guarantee success.
    
   
        In pursuing our objective, we normally invest primarily (at least 80% of
the Fund's total assets) in EQUITY-RELATED AND DEBT SECURITIES OF UTILITY
COMPANIES. This means that we concentrate on companies in the electric, gas, gas
pipeline, telephone, telecommunication, water, cable, airport, seaport and toll
road industries. We buy equity-related securities including common stock,
non-convertible preferred stock, warrants and rights that can be exercised to
obtain stock, investments in various types of business ventures, including
partnerships and joint ventures and securities -- like American Depositary
Receipts (ADRs) -- which are certificates representing the right to receive
foreign securities that have been deposited with a U.S. bank (or a foreign
branch of a U.S. bank).
    
   
    We may also buy convertible securities. These are securities -- like bonds,
corporate notes and preferred stock -- that can be converted into the company's
common stock or some other equity security. Our investment in debt securities is
limited to those rated investment grade by a major rating service or, if not
rated, we believe are of comparable quality. Generally, we consider selling a
security when it has increased in price to the point where it is no longer
underpriced in the opinion of the investment adviser.
    
   
    For more information, see the "Investment Risks" below and the Statement of
Additional Information, "Description of the Fund, Its Investments and Risks."
The Statement of Additional Information -- which we refer to as the
SAI -- contains additional information about the Fund. To obtain a copy, see the
back cover page of this prospectus.

How the Fund Invests
    
   
    The Fund's investment objective is a fundamental policy that cannot be
changed without shareholder approval. The Board of the Fund can change
investment policies that are not fundamental.
    
 
   
OTHER INVESTMENTS
    
   
We may also make the following investments to increase the Fund's returns or
protect its assets if market conditions warrant.
    
 
   
NON-UTILITY INVESTMENTS
    
   
Under normal circumstances, the Fund may invest up to 20% of its total assets in
securities of issuers not in the utility industry. These include stocks,
fixed-income obligations like bonds and money market instruments.
    
 
   
FOREIGN SECURITIES
    
   
The Fund can invest up to 30% of its total assets in stocks and other equity-
related securities and money market instruments and other investment-grade
fixed-income securities of FOREIGN ISSUERS. For these purposes, we do not
consider ADRs and other similar receipts or shares to be foreign securities.
    
 
   
TEMPORARY DEFENSIVE INVESTMENTS
    
   
In response to adverse market, economic or political conditions, we may
temporarily invest up to 100% of the Fund's assets in money market instruments
or short-term municipal obligations. Investing heavily in these securities
limits our ability to achieve capital appreciation, but can help to preserve the
Fund's assets when the equity markets are unstable.
    
 
   
REPURCHASE AGREEMENTS
    
   
The Fund may also use REPURCHASE AGREEMENTS, where a party agrees to sell a
security to the Fund and then repurchase it at an agreed-upon price at a stated
time. This creates a fixed return for the Fund.
    
 
   
DERIVATIVE STRATEGIES
    
   
We may use alternative investment strategies -- including DERIVATIVES -- to try
to improve the Fund's returns or protect its assets, although we cannot
guarantee these strategies will work, that the instruments necessary to
implement these strategies will be available or that the Fund will not lose

money. Derivatives -- such as futures, options, foreign currency forward
contracts and options on futures -- involve costs and can be volatile. With
derivatives, the investment adviser tries to predict whether the underlying
investment, a security, market index, currency, interest rate or some other
investment, will go up or down at some future date. We may use derivatives to
try to reduce risk or to increase return consistent with the Fund's overall
investment objective. The investment adviser will consider other factors (such
as cost) in deciding whether to employ any particular strategy or use any
particular instrument. Any derivatives we may use may not match the Fund's
underlying holdings. For more information about these strategies, see the SAI,
"Description of the Fund, Its Investments and Risks -- Risk Management and
Return Enhancement Strategies."
    
   
ADDITIONAL STRATEGIES
    
   
The Fund also follows certain policies when it BORROWS MONEY (the Fund can
borrow up to 20% of the value of it total assets); LENDS IT SECURITIES to others
(the Fund can lend up to 33% of the value of its total assets, including
collateral received in the transaction); and holds ILLIQUID SECURITIES (the Fund
may hold up to 15% of its net assets in illiquid securities, including
securities with legal or contractual restrictions, those without a readily
available market and repurchase agreements with maturities longer than seven
days). The Fund is subject to certain investment restrictions that are
fundamental policies, and cannot be changed without shareholder approval. For
more information about these restrictions, see the SAI.

YEAR 2000 READINESS DISCLOSURE
    
   
Many computer systems used today cannot distinguish the year 2000 from the year
1900 because of the way dates are encoded. This could be a problem when the year
2000 arrives and could affect securities trades, interest and dividend payments,
pricing and account services. Although we cannot guarantee that this will not be
a problem, the Fund's service providers have been working on adapting their
computer systems. They expect that their systems, and the systems of their
service providers, will be ready for the year 2000.
    
   
    In addition, issuers of securities may also encounter year 2000 compliance
problems. If these problems are significant and are not corrected, securities
markets could go down or issuers could have poor performance. If the Fund owns
these securities, then it is possible that the Fund could lose money.

Fund Distributions
and Tax Issues
    
 
   
Investors who buy shares of the Fund should be aware of some important tax
issues. For example, the Fund distributes DIVIDENDS of ordinary income and any
realized net CAPITAL GAINS to shareholders. These distributions are subject to
taxes, unless you hold your shares in a 401(k) plan, an Individual Retirement
Account (IRA) or some other qualified tax-deferred plan or account.
    
   
    Also, if you sell shares of the Fund for a profit, you may have to pay
capital gains taxes on the amount of your profit, again unless you hold your
shares in a qualified tax-deferred plan or account.
    
   
    The following briefly discusses some of the important federal tax issues you
should be aware of, but is not meant to be tax advice. For tax advice, please
speak with your tax adviser.
    
 
DISTRIBUTIONS
   
The Fund distributes DIVIDENDS of any net investment income to shareholders,
typically every quarter. For example, if the Fund owns ACME Corp. stock and the
stock pays a dividend, the Fund will pay out a portion of this dividend to its
shareholders, assuming the Fund's income is more than its costs and expenses.
The dividends you receive from the Fund will be taxed as ordinary income,
whether or not they are reinvested in the Fund.
    
   
    The Fund also distributes realized net CAPITAL GAINS to shareholders --
typically once a year -- which are generated when the Fund sells its assets for
a profit. For example, if the Fund bought 100 shares of ACME Corp. stock for a
total of $1,000 and more than one year later sold the shares for a total of
$1,500, the Fund has net long-term capital gains of $500, which it will pass on
to shareholders (assuming the Fund's total gains are greater than any losses it
may have). Capital gains are taxed differently depending on how long the Fund
holds the security -- if a security is held more than one year before it is
sold, LONG-TERM capital gains are taxed at the rate of 20% but if the security
is held one year or less, SHORT-TERM capital gains are taxed at ordinary income
rates of up to 39.6%. Different rates apply to corporate shareholders.
    
   
    For your convenience, Fund distributions of dividends and capital gains are
AUTOMATICALLY REINVESTED in the Fund without any sales charge. If you ask us to
pay the distributions in cash, we will send you a check if your account is with
the Transfer Agent. Otherwise, if your account is with a broker you will receive
a credit to your account. Either way, the distributions

may be subject to taxes, unless your shares are held in a qualified tax-deferred
plan or account. For more information about automatic reinvestment and other
shareholder services, see "Step 4: Additional Shareholder Services" in the next
section.
    
 
   
TAX ISSUES
    
   
FORM 1099
    
   
Every year, you will receive a Form 1099, which reports the amount of dividends
and capital gains we distributed to you during the prior year. If you own shares
of the Fund as part of a qualified tax-deferred plan or account, your taxes are
deferred, so you will not receive a Form 1099. However, you will receive a Form
1099 when you take any distributions from your qualified tax-deferred plan or
account.
    
   
    Fund distributions are generally taxable to you in the year they are
received, except when we declare certain dividends in the fourth quarter and
actually pay them in January of the following year. In such cases, the dividends
are treated as if they were paid on December 31 of the prior year. Corporate
shareholders are eligible for the 70% dividends-received deduction for certain
dividends.
    
 
   
WITHHOLDING TAXES
    
   
If federal tax law requires you to provide the Fund with your tax identification
number and certifications as to your tax status, and you fail to do this, we
will withhold and pay to the U.S. Treasury 31% of your distributions and sale
proceeds. If you are subject to backup withholding, we will withhold and pay to
the U.S. Treasury 31% of your distributions. Dividends of net investment income
and short-term capital gains paid to a nonresident foreign shareholder generally
will be subject to a U.S. withholding tax of 30%. This rate may be lower,
depending on any tax treaty the U.S. may have with the shareholder's country.
    
 
   
IF YOU PURCHASE JUST BEFORE RECORD DATE
    
   
If you buy shares of the Fund just before the record date (the date that
determines who receives the distribution), that distribution will be paid to
you. As explained above, the distribution may be subject to income or capital
gains taxes. You may think you've done well, since you bought shares one

day and soon after received a distribution. That is not so because when
dividends are paid out, the value of each share of the Fund decreases by the
amount of the dividend and the market changes (if any) to reflect the payout.
The distribution you receive makes up for the decrease in share value. However,
the timing of your purchase does mean that part of your investment came back to
you as taxable income.
    
 
   
QUALIFIED RETIREMENT PLANS
    
   
Retirement plans and accounts allow you to defer paying taxes on investment
income and capital gains. Contributions to these plans may also be tax
deductible, although distributions from these plans generally are taxable. In
the case of Roth IRA accounts, contributions are not tax deductible, but
distributions from the plan may be tax-free. Please contact your financial
adviser for information on a variety of Prudential Mutual Funds that are
suitable for retirement plans offered by Prudential.
    
 
   
IF YOU SELL OR EXCHANGE YOUR SHARES
    
   
If you sell any shares of the Fund for a profit, you have realized a capital
gain, which is subject to tax unless you hold shares in a qualified tax-deferred
plan or account. The amount of tax you pay depends on how long you owned your
shares. If you sell shares of the Fund for a loss, you may have a capital loss,
which you may use to offset certain capital gains you have.
    
   
    Exchanging your shares of the Fund for the shares of another Prudential
Mutual Fund is considered a sale for tax purposes. In other words, it's a
"taxable event." Therefore, if the shares you exchanged have increased in value
since you purchased them, you have capital gains, which are subject to the taxes
described above.
    
   
    Any gain or loss you may have from selling or exchanging Fund shares will
not be reported on the Form 1099. Therefore, unless you hold your shares in a
qualified tax-deferred plan or account, you or your financial

adviser should keep track of the dates on which you buy and sell -- or
exchange -- Fund shares, as well as the amount of any gain or loss on each
transaction. For tax advice, please see your tax adviser.
    
 
   
AUTOMATIC CONVERSION OF CLASS B SHARES
    
   
We have obtained a legal opinion that the conversion of Class B shares into
Class A shares -- which happens automatically approximately seven years after
purchase -- is not a "taxable event" because it does not involve an actual sale
of your Class B shares. This opinion, however, is not binding on the IRS. For
more information about the automatic conversion of Class B shares, see "Class B
Shares Convert to Class A Shares After Approximately Seven Years" in the next
section.

HOW TO BUY SHARES
    
   
STEP 1: OPEN AN ACCOUNT
    
   
If you don't have an account with us or a securities firm that is permitted to
buy or sell shares of the Fund for you, call Prudential Mutual Fund Services LLC
(PMFS) at (800) 225-1852 or contact:
    
 
   
PRUDENTIAL MUTUAL FUND SERVICES LLC
ATTN: INVESTMENT SERVICES
P.O. BOX 15020
NEW BRUNSWICK, NJ 08906-5020
    
 
   
    To purchase by wire, call the number above to obtain an application. After
PMFS receives your completed application, you will receive an account number.
For additional information about purchasing shares of the Fund, see the back
cover page of this prospectus. We have the right to reject any purchase order
(including an exchange into the Fund) or suspend or modify the Fund's sale of
its shares.
    
 
   
STEP 2: CHOOSE A SHARE CLASS
    
   
Individual investors can choose among Class A, Class B, Class C and Class Z
shares of the Fund, although Class Z shares are available only to a limited
group of investors.
    
   
    Multiple share classes let you choose a cost structure that better meets
your needs. With Class A shares, you pay the sales charge at the time of
purchase, but the operating expenses each year are lower than the expenses of
Class B and Class C shares. With Class B shares, you only pay a sales charge if
you sell your shares within six years (that is why it is called a Contingent
Deferred Sales Charge, or CDSC), but the operating expenses each year are higher
than the Class A share expenses. With Class C shares, you pay a 1% front-end
sales charge and a 1% CDSC if you sell within 18 months of purchase, but the
operating expenses are also higher than the expenses for Class A shares.
    
   
    When choosing a share class, you should consider the following:
    
 
   
     -    The amount of your investment
    
 
   
     -    The length of time you expect to hold the shares and the impact of
          varying distribution fees

BENEFIT PLANS. Benefit Plans can avoid Class A's initial sales charge if the
Benefit Plan has existing assets of at least $1 million invested in shares of
Prudential Mutual Funds (excluding money market funds other than those acquired
under the exchange privilege) or 250 eligible employees or participants. For
these purposes, a Benefit Plan is a pension, profit-sharing or other employee
benefit plan qualified under Section 401 of the Internal Revenue Code, a
deferred compensation or annuity plan under Sections 403(b) and 457 of the
Internal Revenue Code, a "rabbi" trust or a non-qualified deferred compensation
plan sponsored by an employer that has a tax-qualified benefit plan with
Prudential. Class A shares may also be purchased without a sales charge by
participants who are repaying loans from Benefit Plans where Prudential (or its
affiliates) provides administrative or recordkeeping services, sponsors the
product or provides account services.
    
   
    Certain Prudential retirement programs -- such as PruArray Association
Benefit Plans and PruArray Savings Programs -- may also be exempt from Class A's
sales charge. For more information, see the SAI or contact your financial
adviser. In addition, waivers are available to investors in certain programs
sponsored by brokers, investment advisers and financial planners who have
agreements with Prudential Investments Advisory Group relating to:
    
 
   
     -    Mutual fund "wrap" or asset allocation programs where the sponsor
          places Fund trades and charges its clients a management, consulting or
          other fee for its services; and
    
 
   
     -    Mutual fund "supermarket" programs where the sponsor links its
          customers' accounts to a master account in the sponsor's name and the
          sponsor charges a fee for its services.
    
 
   
OTHER TYPES OF INVESTORS. Other investors pay no sales charges, including
certain officers, employees or agents of Prudential and its affiliates,
Prudential Mutual Funds, the subadvisers of the Prudential Mutual Funds and
clients of brokers that have entered into a selected dealer agreement with the
Distributor. To qualify for a reduction or waiver of the sales charge, you must
notify the Transfer Agent or your broker at the time of purchase. For more
information, see the SAI, "Purchase, Redemption and Pricing of Fund

WAIVING CLASS C'S INITIAL SALES CHARGE
    
   
BENEFIT PLANS. Benefit Plans (as defined above) may purchase Class C shares
without paying an initial sales charge. Class C shares may also be purchased
without an initial sales charge by participants who are repaying loans from
Benefit Plans where Prudential (or its affiliates) provides administrative or
recordkeeping services, sponsors the product or provides account services.
    
 
   
PRUDENTIAL RETIREMENT PLANS. The initial sales charge will be waived for
purchases of Class C shares by both qualified and non-qualified retirement and
deferred compensation plans participating in the PruArray Plan and other plans
if Prudential also provides administrative or recordkeeping services.
    
 
   
INVESTMENT OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. The initial
sales charge will be waived for purchases of Class C shares if the purchase is
made with money from the redemption of shares of any unaffiliated investment
company, as long as the shares were not held in an account at Prudential
Securities Incorporated or one of its affiliates. These purchases must be made
within 60 days of the redemption. To qualify for this waiver, you must:
    
 
   
     -    purchase your shares through an account at Prudential Securities,
    
 
   
     -    purchase your shares through an ADVANTAGE Account or an Investor
          Account with Pruco Securities Corporation, or
    
 
   
     -    purchase your shares through another broker.
    
   
    This waiver is not available to investors who purchase shares directly from
the Transfer Agent. If you are entitled to the waiver, you must notify either
the Transfer Agent or your broker. The Transfer Agent may require any supporting
documents it considers appropriate.
    
 
   
QUALIFYING FOR CLASS Z SHARES
    
   
Class Z shares of the Fund can be purchased by any of the following:
    
 
   
     -    Any Benefit Plan as defined above, and certain non-qualified plans,
          provided the Benefit Plan -- in combination with other plans sponsored
          by the same employer or group of related employers -- has at least $50
          million in defined contribution assets

          in a Prudential-sponsored employee savings plan
    
 
   
     -    Prudential with an investment of $10 million or more
    
 
   
    In connection with the sale of shares, the Manager, the Distributor or one
of their affiliates may pay brokers, financial advisers and other persons a
commission of up to 4% of the purchase price for Class B shares, up to 2% of the
purchase price for Class C shares and a finder's fee for Class Z shares from
their own resources based on a percentage of the net asset value of shares sold
or otherwise.
    
 
   
CLASS B SHARES CONVERT TO CLASS A SHARES AFTER APPROXIMATELY SEVEN YEARS
    
   
If you buy Class B shares and hold them for approximately seven years, we will
automatically convert them into Class A shares without charge. At that time, we
will also convert any Class B shares that you purchased with reinvested
dividends and other distributions. Since the 12b-1 fees for Class A shares are
lower than for Class B shares, converting to Class A shares lowers your Fund
expenses.
    
   
    When we do the conversion, you will get fewer Class A shares than the number
of Class B shares converted if the price of the Class A shares is higher than
the price of Class B shares. The total dollar value will be the same, so you
will not have lost any money by getting fewer Class A shares. We do the
conversions quarterly, not on the anniversary date of your

purchase. For more information, see the SAI, "Purchase, Redemption and Pricing
of Fund Shares -- Conversion Feature -- Class B Shares."
    
 
   
STEP 3: UNDERSTANDING THE PRICE YOU'LL PAY
    
   
The price you pay for each share of the Fund is based on the share value. The
share value of a mutual fund -- known as the NET ASSET VALUE or NAV -- is
determined by a simple calculation -- it's the total value of the Fund (assets
minus liabilities) divided by the total number of shares outstanding. For
example, if the value of the investments held by Fund XYZ (minus its
liabilities) is $1,000 and there are 100 shares of Fund XYZ owned by
shareholders, the price of one share of the fund -- or the NAV -- is $10 ($1,000
divided by 100). Portfolio securities are valued based upon market quotations
or, if not readily available, at fair value as determined in good faith under
procedures established by the Fund's Board. Most national newspapers report the
NAVs of most mutual funds, which allows investors to check the price of mutual
funds daily.
    
   
    We determine the NAV of our shares once each business day at 4:15 p.m. New
York Time on days that the New York Stock Exchange is open for trading. We do
not determine NAV on days when we have not received any orders to purchase, sell
or exchange Fund shares, or when changes in the value of the Fund's portfolio do
not materially affect the NAV.
    
 
   
WHAT PRICE WILL YOU PAY FOR SHARES OF THE FUND?
    
   
For Class A and Class C shares, you'll pay the public offering price, which is
NAV next determined after we receive your order to purchase, plus an initial
sales charge (unless you're entitled to a waiver). For Class B and Class Z
shares, you will pay the NAV next determined after we receive your order to
purchase (remember, there are no up-front sales charges for these share
 
- -------------------------------------------------------------------
    
MUTUAL FUND SHARES
   
The NAV of mutual fund shares changes every day because the value of a fund's
portfolio changes constantly. For example, if Fund XYZ holds ACME Corp. stock in
its portfolio and the price of ACME stock goes up, while the value of the fund's
other holdings remains the same and expenses don't change, the NAV of Fund XYZ
will increase.

classes). Your broker may charge you a separate or additional fee for purchases
of shares.
    
 
   
STEP 4: ADDITIONAL SHAREHOLDER SERVICES
    
   
As a Fund shareholder, you can take advantage of the following services and
privileges:
    
 
   
AUTOMATIC REINVESTMENT. As we explained in the "Fund Distributions and Tax
Issues" section, the Fund pays out -- or distributes -- its net investment
income and capital gains to all shareholders. For your convenience, we will
automatically reinvest your distributions in the Fund at NAV, without any sales
charge. If you want your distributions paid in cash, you can indicate this
preference on your application, notify your broker or notify the Transfer Agent
in writing (at the address below) at least five business days before the date we
determine who receives dividends:

AUTOMATIC INVESTMENT PLAN. You can make regular purchases of the Fund for as
little as $50 by having the funds automatically withdrawn from your bank or
brokerage account at specified intervals.
    
 
   
RETIREMENT PLAN SERVICES. Prudential offers a wide variety of retirement plans
for individuals and institutions, including large and small businesses. For
information on IRAs, including Roth IRAs, or SEP-IRAs for a one-person business,
please contact your financial adviser. If you are interested in opening a 401(k)
or other company-sponsored retirement plan (SIMPLES, SEP plans, Keoghs,
403(b)(7) plans, pension and profit-sharing plans), your financial adviser will
help you determine which retirement plan best meets your needs. Complete
instructions about how to establish and maintain your plan and how to open
accounts for you and your employees will be included in the retirement plan kit
you receive in the mail.

THE PRUTECTOR PROGRAM. Optional group term life insurance -- which protects the
value of your Prudential Mutual Fund investment for your beneficiaries against
market declines -- is available to investors who purchase their shares through
Prudential. This insurance is subject to various restrictions and charges and is
not available in all states.
    
 
   
SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available that will
provide you with monthly or quarterly checks. Remember, the sale of Class B and
Class C shares may be subject to a CDSC.
    
 
   
REPORTS TO SHAREHOLDERS. Every year we will send you an annual report (along
with an updated prospectus) and a semi-annual report, which contain important
financial information about the Fund. To reduce Fund expenses, we will send one
annual shareholder report, one semi-annual shareholder report and one annual
prospectus per household, unless you instruct us or your broker otherwise.
    
 
   
HOW TO SELL YOUR SHARES
    
   
You can sell your shares of the Fund for cash (in the form of a check) at any
time, subject to certain restrictions.
    
   
    When you sell shares of the Fund -- also known as redeeming your
shares -- the price you will receive will be the NAV next determined after the
Transfer Agent, the Distributor or your broker receives your order to sell. If
your broker holds your shares, he must receive your order to sell by 4:15 p.m.
New York time to process the sale on that day. Otherwise, contact:

    Generally, we will pay you for the shares that you sell within seven days
after the Transfer Agent, the Distributor or your broker receives your sell
order. If you hold shares through a broker, payment will be credited to your
account. If you are selling shares you recently purchased with a check, we may
delay sending you the sale proceeds until your check clears, which can

take up to 10 days from your purchase date. You can avoid delay if you purchase
shares by wire, certified check or cashier's check. Your broker may charge you a
separate or additional fee for sales of shares.
    
 
   
RESTRICTIONS ON SALES
    
   
There are certain times when you may not be able to sell shares of the Fund, or
when we may delay paying you the proceeds from a sale. This may happen during
unusual market conditions or emergencies when the Fund can't determine the value
of its assets or sell its holdings. For more information, see the SAI,
"Purchase, Redemption and Pricing of Fund Shares -- Sale of Shares."
    
   
    If you are selling more than $50,000 of shares, you want the check sent to
someone or some place that is not in our records, or you are a business or a
trust and if you hold your shares directly with the Transfer Agent, you may have
to have the signature on your sell order guaranteed by a financial institution.
For more information, see the SAI, "Purchase, Redemption and Pricing of Fund
Shares -- Sale of Shares -- Signature Guarantee."
    
 
   
CONTINGENT DEFERRED SALES CHARGES (CDSC)
    
   
If you sell Class B shares within six years of purchase or Class C shares within
18 months of purchase (1 year for Class C shares purchased before November 2,
1998), you will have to pay a CDSC. To keep the CDSC as low as possible, we will
sell amounts representing shares in the following order:
    
 
   
     -    Amounts representing shares you purchased with reinvested dividends
          and distributions
    
 
   
     -    Amounts representing the increase in NAV above the total amount of
          payments for shares made during the past six years for Class B shares
          (five years for Class B shares purchased before January 22, 1990) and
          18 months for Class C shares
    
 
   
     -    Amounts representing the cost of shares held beyond the CDSC period
          (six years for Class B shares and 18 months for Class C shares)
    
 
   
     -    Amounts representing the cost of shares acquired prior to July 1, 1985
    
 
                                                           27
<PAGE>
   
How to Buy, Sell and Exchange
Shares of the Fund
    
 
   
    Since shares that fall into any of the categories listed above are not
subject to the CDSC, selling them first helps you to avoid -- or at least
minimize -- the CDSC.
    
   
    Having sold the exempt shares first, if there are any remaining shares that
are subject to the CDSC, we will apply the CDSC to amounts representing the cost
of shares held for the longest period of time within the applicable CDSC period.
    
   
    As we noted before in the "Share Class Comparison" chart, the CDSC for Class
B shares is 5% in the first year, 4% in the second, 3% in the third, 2% in the
fourth and 1% in the fifth and sixth years. The rate decreases on the first day
of the month following the anniversary date of your purchase, not on the
anniversary date itself. The CDSC is 1% for Class C shares -- which is applied
to shares sold within 18 months of purchase (one year for Class C shares
purchased before November 2, 1998). For both Class B and Class C shares, the
CDSC is the lesser of the original purchase price or the redemption proceeds.
For purposes of determining how long you've held your shares, all purchases
during the month are grouped together and considered to have been made on the
last day of the month.
    
   
    The holding period for purposes of determining the applicable CDSC will be
calculated from the first day of the month after initial purchase, excluding any
time shares were held in a money market fund.
    
 
   
WAIVER OF THE CDSC -- CLASS B SHARES
    
   
The CDSC will be waived if the Class B shares are sold:
    
 
   
     -    After a shareholder is deceased or disabled (or, in the case of a
          trust account, the death or disability of the grantor). This waiver
          applies to individual shareholders, as well as shares owned in joint
          tenancy (with rights of survivorship), provided the shares were
          purchased before the death or disability
    
 
   
     -    To provide for certain distributions -- made without IRS penalty --
          from a tax-deferred retirement plan, IRA or Section 403(b) custodial
          account
    
 
   
     -    On certain sales from a Systematic Withdrawal Plan
    
 
   
    For more information on the above and other waivers, see the SAI, "Purchase,
Redemption and Pricing of Fund Shares -- Waiver of Contingent Deferred Sales
Charges -- Class B Shares."

Shares of the Fund
    
 
   
WAIVER OF THE CDSC -- CLASS C SHARES
    
   
PRUDENTIAL RETIREMENT PLANS. The CDSC will be waived for purchases of Class C
shares by both qualified and non-qualified retirement and deferred compensation
plans participating in the PruArray Plan and other plans if Prudential also
provides administrative or recordkeeping services. The CDSC will also be waived
on redemptions from Benefit Plans sponsored by Prudential and its affiliates to
the extent that the redemption proceeds are invested in The Guaranteed
Investment Account (a group annuity insurance product sponsored by Prudential),
the Guaranteed Insulated Separate Account (a separate account offered by
Prudential), and shares of The Stable Value Fund (an unaffiliated bank
collective fund).
    
 
   
OTHER BENEFIT PLANS. The CDSC will be waived on redemptions from Benefit Plans
holding shares through a broker not affiliated with Prudential and for which the
broker provides administrative or recordkeeping services.
    
 
   
REDEMPTION IN KIND
    
   
If the sales of Fund shares you make during any 90-day period reach the lesser
of $250,000 or 1% of the value of the Fund's net assets, we can then give you
securities from the Fund's portfolio instead of cash. If you want to sell the
securities for cash, you would have to pay the costs charged by a broker.
    
 
   
SMALL ACCOUNTS
    
   
If you make a sale that reduces your account value to less than $500, we may
sell the rest of your shares (without charging any CDSC) and close your account.
We would do this to minimize the Fund's expenses paid by other shareholders. We
will give you 60 days' notice, during which time you can purchase additional
shares to avoid this action. This involuntary sale does not apply to
shareholders who own their shares as part of a 401(k) plan, an IRA or some other
tax-deferred plan or account.
    
 
   
90-DAY REPURCHASE PRIVILEGE
    
   
After you redeem your shares, you have a 90-day period during which you may
reinvest any of the redemption proceeds in shares of the same Fund without
paying an initial sales charge. Also, if you paid a CDSC when you
    
 
                                                           29

How to Buy, Sell and Exchange
Shares of the Fund
    
   
redeemed your shares, we will credit your new account with the appropriate
numbers of shares to reflect the amount of the CDSC you paid. In order to take
advantage of this one-time privilege, you must notify the Transfer Agent or your
broker at the time of the repurchase. See the SAI, "Purchase, Redemption and
Pricing of Fund Shares -- Sale of Shares."
    
 
   
RETIREMENT PLANS
    
   
To sell shares and receive a distribution from a retirement account, call your
broker or the Transfer Agent for a distribution request form. There are special
distribution and income tax withholding requirements for distributions from
retirement plans and you must submit a withholding form with your request to
avoid delay. If your retirement plan account is held for you by your employer or
plan trustee, you must arrange for the distribution request to be signed and
sent by the plan administrator or trustee. For additional information, see the
SAI.
    
 
   
HOW TO EXCHANGE YOUR SHARES
    
   
You can exchange your shares of the Fund for shares of the same class in certain
other Prudential Mutual Funds -- including certain money market funds -- if you
satisfy the minimum investment requirements. For example, you can exchange Class
A shares of the Fund for Class A shares of another Prudential Mutual Fund, but
you can't exchange Class A shares for Class B, Class C or Class Z shares. Class
B and Class C shares may not be exchanged into money market funds other than
Prudential Special Money Market Fund, Inc. After an exchange, at redemption the
CDSC will be calculated from the first day of the month after initial purchase,
excluding any time shares were held in a money market fund. We may change the
terms of the exchange privilege after giving you 60 days' notice.
    
   
    If you hold shares through a broker, you must exchange shares through your
broker. Otherwise contact:

Shares of the Fund
    
 
   
    There is no sales charge for such exchanges. However, if you exchange -- and
then sell -- Class B shares within approximately six years of your original
purchase or Class C shares within 18 months of your original purchase, you must
still pay the applicable CDSC. If you have exchanged Class B or Class C shares
into a money market fund, the time you hold the shares in the money market
account will not be counted in calculating the required holding period for CDSC
liability.
    
   
    Remember, as we explained in the section entitled "Fund Distribution and Tax
Issues -- If You Sell or Exchange Your Shares," exchanging shares is considered
a sale for tax purposes. Therefore, if the shares you exchange are worth more
than you paid for them, you may have to pay capital gains tax. For additional
information about exchanging shares, see the SAI, "Shareholder Investment
Account -- Exchange Privilege."
    
   
    If you own Class B or Class C shares and qualify to purchase either Class A
shares without paying an initial sales charge or Class Z shares, we will
automatically exchange your Class B or Class C shares which are not subject to a
CDSC for Class A or Class Z shares, as appropriate. We make such exchanges on a
quarterly basis if you qualify for this exchange privilege. We have obtained
legal opinion that this exchange is not a "taxable event" for federal income tax
purposes. This opinion is not binding on the IRS.
    
 
   
FREQUENT TRADING
    
   
Frequent trading of Fund shares in response to short-term fluctuations in the
market -- also known as "market timing" -- may make it very difficult to manage
the Fund's investments. Also when market timing occurs, the Fund may have to
sell portfolio securities to have the cash necessary to redeem the market
timer's shares. This can happen at a time when it is not advantageous to sell
any securities, so the Fund's performance may be hurt. When large dollar amounts
are involved, market timing can also make it difficult to use long-term
investment strategies because we cannot predict how much cash the Fund will have
to invest. When in our opinion such activity would have a disruptive effect on
portfolio management, the Fund reserves the right to refuse purchase orders and
exchanges into the Fund by any person, group or commonly controlled accounts.
The Fund may notify a market timer of rejection of an exchange or purchase order
subsequent to the day the order is placed. If the Fund allows a market timer to
trade Fund shares, it may require the market timer to enter into a written
agreement to follow certain procedures and limitations.

                      STATEMENT OF ADDITIONAL INFORMATION
                                 MARCH 1, 1999
    
 
   
    Prudential Utility Fund, Inc. (the Fund), is an open-end, diversified,
management investment company. Its investment objective is to seek total return
through a combination of current income and capital appreciation. The Fund seeks
to achieve its objective through investment in equity-related and debt
securities of utility companies, which include electric, gas, gas pipeline,
telephone, telecommunications, water, cable, airport, seaport and toll road
companies. In normal circumstances, the Fund intends to invest at least 80% of
its assets in such securities. It is anticipated that the Fund will invest
primarily in common stocks of utility companies that the Subadviser believes
have the potential for total return; however, the Fund may invest primarily in
preferred stocks and debt securities of utility companies when it appears that
the Fund will be better able to achieve its investment objective through
investments in such securities, or when the Fund is temporarily in a defensive
position. The remaining 20% of its assets may be invested in other securities,
including stocks, debt obligations and money market instruments, as well as
certain derivative instruments. Moreover, should extraordinary conditions
affecting such sectors or securities markets as a whole warrant, the Fund may
temporarily be primarily invested in money market instruments. There can be no
assurance that the Fund's investment objective will be achieved. See
"Description of the Fund, Its Investments and Risks."
    
 
    The Fund's address is Gateway Center Three, 100 Mulberry Street, Newark, New
Jersey 07102-4077, and its telephone number is (800) 225-1852.
 
   
    This Statement of Additional Information is not a prospectus and should be
read in conjunction with the Fund's Prospectus dated March 1, 1999, a copy of
which may be obtained from the Fund upon request.

                                  FUND HISTORY
    
 
    At a special meeting held on July 19, 1994, shareholders approved an
amendment to the Fund's Articles of Incorporation to change the Fund's name from
Prudential-Bache Utility Fund, Inc. to Prudential Utility Fund, Inc.
 
   
               DESCRIPTION OF THE FUND, ITS INVESTMENTS AND RISKS
    
 
   
    (A) CLASSIFICATION. The Fund is a diversified, open-end management
investment company.
    
 
   
    (B) AND (C) INVESTMENT STRATEGIES, POLICIES AND RISKS. The Fund's investment
objective is to seek total return through a combination of current income and
capital appreciation. While the principal investment policies and strategies for
seeking to achieve this objective are described in the Fund's Prospectus, the
Fund may from time to time also use the securities, instruments, policies and
strategies described below in seeking to achieve its objective. The Fund may not
be successful in achieving its objective and you could lose money.
    
 
   
FOREIGN SECURITIES
    
 
   
    The Fund may invest up to 30% of its total assets in foreign securities. In
many instances, foreign debt securities may provide higher yields but may be
subject to greater fluctuations in price than securities of domestic issuers
which have similar maturities and quality. Under certain market conditions,
these investments may be less liquid than the securities of U.S. corporations
and are certainly less liquid than securities issued or guaranteed by the U.S.
Government, its instrumentalities or agencies.
    
 
   
    Foreign securities involve certain risks which should be considered
carefully by an investor in the Fund. These risks include exchange rate
fluctuations, political, social or economic instability of the country of issue,
diplomatic developments which could affect the assets of the Fund held in
foreign countries, and the possible imposition of exchange controls, withholding
taxes on dividends or interest payments, confiscatory taxes or expropriation.
There may be less government supervision and regulation of foreign securities
exchanges, brokers and listed companies than exists in the United States,
foreign brokerage commissions and custody fees are generally higher than those
in the United States, and foreign security settlements will in some instances be
subject to delays and related administrative uncertainties. The Fund will
probably have greater difficulty in obtaining or enforcing a court judgment
abroad than it would have doing so within the United States. Less information
may be publicly available about a foreign company than about a domestic company,
and foreign companies may not be subject to uniform accounting, auditing and
financial reporting standards comparable to those applicable to domestic
companies. In addition, foreign securities markets have substantially less
volume than the New York Stock Exchange and securities of some foreign companies
are less liquid and more volatile than securities of comparable U.S. companies.
    
 
   
    Although the foreign companies in which the Fund may invest will be
providing products and services substantially similar to domestic companies in
which the Fund has and may invest, the utility companies of many major
countries, such as the United Kingdom, Spain and Mexico, have only recently
substantially increased investor ownership (including ownership by U.S.
investors) and, as a result, have only recently become subject to adversarial
rate-making procedures. In addition, certain foreign utilities are experiencing
demand growth at rates greater than economic expansion in their countries or
regions. These factors as well as those associated with foreign issuers
generally may affect the future values of foreign securities held by the Fund.
    
 
   
RISK FACTORS AND SPECIAL CONSIDERATIONS OF INVESTING IN EURO-DENOMINATED
SECURITIES
    
 
   
    On January 1, 1999, 11 of the 15 member states of the European Monetary
Union introduced the "euro" as a common currency. During a three-year
transitional period, the euro will coexist with each participating state's
currency and, on July 1, 2002, the euro is expected to become the sole currency
of the participating states. During the transition period, the Fund will treat
the euro as a separate currency from that of any participating state.
    
 
   
    The conversion may adversely affect the Fund if the euro does not take
effect as planned; if a participating state withdraws from the European Monetary
Union; or if the computing, accounting and trading systems used by the Funds'
    
 
                                      B-2
<PAGE>
   
service providers, or by entities with which the Fund or its service providers
do business, are not capable of recognizing the euro as a distinct currency at
the time of, and following, euro conversion. In addition, the conversion could
cause markets to become more volatile.
    
 
   
    The overall effect to the transition of member states' currencies to the
euro is not known at this time. It is likely that more general short- and
long-term ramifications can be expected, such as changes in the economic
environment and change in the behavior of investors, which would affect the
Fund's investments and its net asset value. In addition, although U.S. Treasury
regulations generally provide that the euro conversion will not, in itself,
cause a U.S. taxpayer to realize gain or loss, other changes that may occur at
the time of the conversion, such as accrual periods, holiday conventions,
indices, and other features may require the realization of a gain or loss by the
Fund as determined under existing tax law.
    
 
   
    The Fund's Manager is taking steps: (1) that it believes will reasonably
address euro-related changes to enable the Fund to process transactions
accurately and completely with mininal disruption to business activities and (2)
to obtain reasonable assurances that appropriate steps have been taken by the
Fund's other service providers to address the conversion.
    
 
   
RISK MANAGEMENT AND RETURN ENHANCEMENT STRATEGIES
    
 
   
    The Fund may also engage in various portfolio strategies, including using
derivatives, to seek to reduce certain risks of its investments and to enhance
return. These strategies include (1) the purchase and writing (that is, sale) of
put and call options on equity securities and on stock indices, (2) the purchase
and sale of listed stock and bond index futures and options thereon and (3) the
purchase and sale of options on foreign currencies and futures contracts on
foreign currencies and options on such contracts. The Fund may engage in these
transactions on U.S. or foreign securities exchanges or, in the case of equity
and stock index options, in the over-the-counter market. The Fund may also
purchase and sell foreign currency forward contracts. The Fund, and thus its
investors, may lose money through any unsuccessful use of these strategies. The
Fund's ability to use these strategies may be limited by various factors, such
as market conditions, regulatory limits and tax considerations, and there can be
no assurance that any of these strategies will succeed. If new financial
products and risk management techniques are developed, the Fund may use them to
the extent they are consistent with its investment objective and policies.
    
 
OPTIONS ON EQUITY SECURITIES
 
   
    The Fund may purchase and write (that is, sell) put and call options on
equity securities that are traded on securities exchanges, on NASDAQ (NASDAQ
options) or in the over-the-counter market (OTC options).
    
 
   
    CALL OPTIONS ON STOCK. A call option is a short-term contract which gives
the purchaser, in return for a premium paid, the right to buy the security
subject to the option at a specified exercise price at any time during the term
of the option. The writer of the call option, in return for the premium, has the
obligation, upon exercise of the option, to deliver, depending on the terms of
the option contract, the underlying securities to the purchaser upon receipt of
the exercise price. When the Fund writes a call option, the Fund gives up the
potential for gain on the underlying securities in excess of the exercise price
of the option during the period that the option is open. There is no limitation
on the amount of call options the Fund may write.
    
 
    The Fund may, from time to time, write call options on its portfolio
securities. The Fund may write only call options which are "covered," meaning
that the Fund either owns the underlying security or has an absolute and
immediate right to acquire that security, without additional consideration (or
for additional consideration held in a segregated account by its Custodian),
upon conversion or exchange of other securities currently held in its portfolio.
In addition, the Fund will not permit the call to become uncovered prior to the
expiration of the option or termination through a closing purchase transaction
as described below. If the Fund writes a call option, the purchaser of the
option has the right to buy (and the Fund has the obligation to sell) the
underlying security at the exercise price throughout the term of the option. The
amount paid to the Fund by the purchaser of the option is the "premium." The
Fund's obligation to deliver the underlying security
 
                                      B-3
<PAGE>
against payment of the exercise price would terminate either upon expiration of
the option or earlier if the Fund were to effect a "closing purchase
transaction" through the purchase of an equivalent option on an exchange. There
can be no assurance that a closing purchase transaction can be effected.
 
   
    The Fund would not be able to effect a closing purchase transaction after it
had received notice of exercise. In order to write a call option on an exchange,
the Fund is required to comply with the rules of The Options Clearing
Corporation and the various exchanges with respect to collateral requirements.
It is possible that the cost of effecting a closing purchase transaction may be
greater than the premium received by the Fund for writing the option.
    
 
   
    PUT OPTIONS ON STOCK. A put option gives the purchaser, in return for a
premium, the right, for a specified period of time, to sell the securities
subject to the option to the writer of the put at the specified exercise price.
The writer of the put, in return for the premium, has the obligation, upon
exercise of the option, to acquire the securities underlying the option at the
exercise price. The Fund as the writer of a put option might, therefore, be
obligated to purchase underlying securities for more than their current market
price. If the Fund purchases a put option, it has the option to sell a given
security at a specified price at any time during the term of the option. If the
Fund purchases a call option, it has the option to buy a security at a specified
price at any time during the term of the option.
    
 
   
    The Fund may also purchase a "protective put," that is, a put option
acquired for the purpose of protecting a portfolio security from a decline in
market value. In exchange for the premium paid for the put option, the Fund
acquires the right to sell the underlying security at the exercise price of the
put regardless of the extent to which the underlying security declines in value.
The loss to the Fund is limited to the premium paid for, and transaction costs
in connection with, the put plus the initial excess, if any, of the market price
of the underlying security over the exercise price. However, if the market price
of the security underlying the put rises, the profit the Fund realizes on the
sale of the security will be reduced by the premium paid for the put option less
any amount (net of transaction costs) for which the put may be sold. Similar
principles apply to the purchase of puts on stock indices as described below.
    
 
    Purchasing put options may be used as a portfolio investment strategy when
the investment adviser perceives significant short-term risk but substantial
long-term appreciation for the underlying security. The put option acts as an
insurance policy, as it protects against significant downward price movement
while it allows full participation in any upward movement. If the Fund is
holding a security which it feels has strong fundamentals, but for some reason
may be weak in the near term, it may purchase a put on such security, thereby
giving itself the right to sell such security at a certain strike price
throughout the term of the option. Consequently, the Fund will exercise the put
only if the price of such security falls below the strike price of the put. The
difference between the put's strike price and the market price of the underlying
security on the date the Fund exercises the put, less transaction costs, will be
the amount by which the Fund will be able to hedge against a decline in the
underlying security. If during the period of the option the market price for the
underlying security remains at or above the put's strike price, the put will
expire worthless, representing a loss of the price the Fund paid for the put,
plus transaction costs. If the price of the underlying security increases, the
profit the Fund realizes on the sale of the security will be reduced by the
premium paid for the put option less any amount for which the put may be sold
prior to its expiration.
 
STOCK INDEX OPTIONS
 
   
    The Fund may also purchase and write (that is, sell) put and call options on
stock indices traded on securities exchanges, on NASDAQ or in the OTC market.
Such options may include options on non-utility companies. Options on stock
indices are similar to options on stock except that, rather than the right to
take or make delivery of a stock at a specified price, an option on a stock
index gives the holder the right in return for premium paid to receive, upon
exercise of the option, an amount of cash if the closing level of the index upon
which the option is based is greater than, in the case of a call, or less than,
in the case of a put, the exercise price of the option. The writer of the index
option, in return for a premium, is obligated to pay the amount of cash due upon
exercise of the option. Unlike stock options, all settlements are in cash, and
gain or loss depends on price movements in the underlying market generally (or
in a particular industry or segment of the market) rather than price movements
in individual securities.
    
 
   
    The Fund's successful use of options on indices depends upon the investment
adviser's ability to predict the direction of the market and is subject to
various additional risks. The correlation between movements in the index and the
    
 
                                      B-4
<PAGE>
   
price of the securities being written against is imperfect and the risk from
imperfect correlation increases as the composition of the Fund's portfolio
diverges from the composition of the relevant index. Accordingly, a decrease in
the value of the securities being written against may not be wholly offset by a
gain on the exercise of a stock index put option held by the Fund. Likewise, if
a stock index call option written by the Fund is exercised, the Fund may incur a
loss on the transaction which is not offset, in whole or in part, by an increase
in the value of the securities being written against, which securities may,
depending on market circumstances, decline in value. For additional discussion
of risks associated with these transactions, see "Limitations on Purchase and
Sale of Stock Options, Options on Indices, and Stock and Bond Index Futures and
Options Thereon" below.
    
 
    Except as described below, the Fund will write call options on indices only
if on such date it holds a portfolio of stocks at least equal to the value of
the index times the multiplier times the number of contracts. When the Fund
writes a call option on a broadly-based stock market index, the Fund will
segregate or put into escrow with its Custodian, or pledge to a broker as
collateral for the option, any combination of cash, other liquid assets or
"qualified securities" with a market value at the time the option is written of
not less than 100% of the current index value times the multiplier times the
number of contracts.
 
    If the Fund has written an option on an industry or market segment index, it
will segregate or put into escrow with its Custodian, or pledge to a broker as
collateral for the option, one or more "qualified securities," all of which are
stocks of issuers in such industry or market segment, with a market value at the
time the option is written of not less than 100% of the current index value
times the multiplier times the number of contracts.
 
    If at the close of business on any day the market value of such qualified
securities so segregated, escrowed or pledged falls below 100% of the current
index value times the multiplier times the number of contracts, the Fund will so
segregate, escrow or pledge an amount in cash or other liquid assets equal in
value to the difference. In addition, when the Fund writes a call on an index
which is in-the-money at the time the call is written, the Fund will segregate
with its Custodian or pledge to the broker as collateral cash or other liquid
assets equal in value to the amount by which the call is in-the-money times the
multiplier times the number of contracts. Any amount segregated pursuant to the
foregoing sentence may be applied to the Fund's obligation to segregate
additional amounts in the event that the market value of the qualified
securities falls below 100% of the current index value times the multiplier
times the number of contracts. A "qualified security" is an equity security
which is listed on a securities exchange or listed on NASDAQ against which the
Fund has not written a stock call option and which has not been hedged by the
Fund by the sale of stock index futures. However, if the Fund holds a call on
the same index as the call written where the exercise price of the call held is
equal to or less than the exercise price of the call written or greater than the
exercise price of the call written if the difference is maintained by the Fund
in cash or other liquid assets in a segregated account with its Custodian, it
will not be subject to the requirements described in this paragraph.
 
FUTURES CONTRACTS AND OPTIONS THEREON
 
   
    STOCK AND BOND INDEX FUTURES. The Fund may use listed stock and bond index
futures traded on a commodities exchange or board of trade for certain hedging
and risk management purposes and to attempt to enhance return in accordance with
regulations of the Commodity Futures Trading Commission. The Fund, and thus its
investors, may lose money through any unsuccessful use of these strategies.
    
 
   
    A stock or bond index futures contract is an agreement in which one party
agrees to deliver to the other an amount of cash equal to a specific dollar
amount times the difference between the value of a specific stock or bond index
at the close of the last trading day of the contract and the price at which the
agreement is made. No physical delivery of the underlying stocks in the index is
made.
    
 
   
    Under regulations of the Commodity Exchange Act, investment companies
registered under the Investment Company Act are exempt from the definition of
"commodity pool operator," subject to compliance with certain conditions. The
exemption is conditioned upon the Fund's purchasing and selling futures
contracts and options thereon for bona fide hedging transactions, except that
the Fund may purchase and sell futures contracts and options thereon for any
other purpose to the extent that the aggregate initial margin and option
premiums do not exceed 5% of the liquidation value of the Fund's total assets.
    
 
                                      B-5
<PAGE>
    The Fund will purchase and sell stock and bond index futures contracts as a
hedge against changes resulting from market conditions in the values of
securities which are held in the Fund's portfolio or which it intends to
purchase or when they are economically appropriate for the reduction of risks
inherent in the ongoing management of the Fund or for return enhancement. In
instances involving the purchase of stock or bond index futures contracts by the
Fund, an amount of cash or other liquid assets equal to the market value of the
futures contracts, will be deposited in a segregated account with the Fund's
Custodian and/or in a margin account with a broker or futures commission
merchant to collateralize the position and thereby insure that the use of such
futures is unleveraged.
 
    Pursuant to the requirements of the Commodity Exchange Act, all futures
contracts and options thereon must be traded on an exchange. Therefore, as with
exchange-traded options, a clearing corporation is technically the counterparty
on every futures contract and option thereon.
 
   
    OPTIONS ON STOCK AND BOND INDEX FUTURES CONTRACTS. The Fund may also
purchase and write options on stock and bond index futures for certain hedging
and risk management purposes and to attempt to enhance return. In the case of
options on stock or bond index futures, the holder of the option pays a premium
and receives the right, upon exercise of the option at a specified price during
the option period, to assume a position in a stock or bond index futures
contract (a long position if the option is a call and a short position if the
option is a put). If the option is exercised by the holder before the last
trading day during the option period, the option writer delivers the futures
position, as well as any balance in the writer's futures margin account, which
represents the amount by which the market price of the stock or bond index
futures contract at exercise exceeds, in the case of a call, or is less than, in
the case of a put, the exercise price of the option on the stock or bond index
future. If it is exercised on the last trading day, the option writer delivers
to the option holder cash in an amount equal to the difference between the
option exercise price and the closing level of the relevant index on the date
the option expires.
    
 
    In the case of options on stock or bond index futures, the holder of the
option pays a premium and receives the right, upon exercise of the option at a
specified price during the option period, to assume a position in a stock or
bond index futures contract (a long position if the option is a call and a short
position if the option is a put). If the option is exercised by the holder
before the last trading day during the option period, the option writer delivers
the futures position, as well as any balance in the writer's futures margin
account, which represents the amount by which the market price of the stock or
bond index futures contract at exercise exceeds, in the case of a call, or is
less than, in the case of a put, the exercise price of the option on the stock
or bond index future. If it is exercised on the last trading day, the option
writer delivers to the option holder cash in an amount equal to the difference
between the option exercise price and the closing level of the relevant index on
the date the option expires.
 
   
    FUTURES CONTRACTS ON FOREIGN CURRENCIES. The Fund is permitted to buy and
sell futures contracts on foreign currencies (futures contracts), and purchase
and write options thereon for hedging purposes. The Fund will engage in
transactions in only those futures contracts and options thereon that are traded
on a commodities exchange or a board of trade. A "sale" of a futures contract on
foreign currency means the assumption of a contractual obligation to deliver the
specified amount of foreign currency at a specified price in a specified future
month. A "purchase" of a futures contract means the assumption of a contractual
obligation to acquire the currency called for by the contract at a specified
price in a specified future month. At the time a futures contract is purchased
or sold, the Fund must allocate cash or securities as a deposit payment (initial
margin). Thereafter, the futures contract is valued daily and the payment of
"variation margin" may be required, resulting in the Fund's paying or receiving
cash that reflects any decline or increase, respectively, in the contract's
value, a process known as "mark-to-market."
    
 
   
    The Fund's successful use of futures contracts and options thereon depends
upon the investment adviser's ability to predict the direction of the market and
is subject to various additional risks. The correlation between movements in the
price of a futures contract and the price of the securities being hedged is
imperfect and there is a risk that the value of the securities being hedged may
increase or decrease at a greater rate than the related futures contract,
resulting in losses to the Fund. The use of these instruments will hedge only
the currency risks associated with investments in foreign securities, not market
risks. Certain futures exchanges or boards of trade have established daily
limits on the amount that the price of a futures contract or option thereon may
vary, either up or down, from the previous day's settlement price. These daily
limits may restrict the Fund's ability to purchase or sell certain futures
contracts or options thereon on any
    
 
                                      B-6
<PAGE>
   
particular day. In addition, if the Fund purchases futures to hedge against
market advances before it can invest in stocks or bonds in an advantageous
manner and the market declines, the Fund might incur a loss on the futures
contract. In addition, the ability of the Fund to close out a futures position
or an option depends on a liquid secondary market. There is no assurance that
liquid secondary markets will exist for any particular futures contract or
option thereon at any particular time.
    
 
   
RISKS OF RISK MANAGEMENT AND RETURN ENHANCEMENT STRATEGIES
    
 
   
    Participation in the options or futures markets and in currency exchange
transactions involves investment risks and transaction costs to which the Fund
would not be subject absent the use of these strategies. The Fund, and thus its
investors, may lose money through any unsuccessful use of these strategies. If
the investment adviser's prediction of movements in the direction of the
securities, foreign currency or interest rate markets is inaccurate, the adverse
consequences to the Fund may leave the Fund in a worse position than if such
strategies were not used. Risks inherent in the use of options, foreign currency
and futures contracts and options on futures contracts include: (1) dependence
on the investment adviser's ability to predict correctly movements in the
direction of interest rates, securities prices and currency markets; (2)
imperfect correlation between the price of options and futures contracts and
options thereon and movements in the prices of the securities or currencies
being hedged; (3) the fact that skills needed to use these strategies are
different from those needed to select portfolio securities; (4) the possible
absence of a liquid secondary market for any particular instrument at any time;
(5) the risk that the counterparty may be unable to complete the transaction;
and (6) the possible inability of the Fund to purchase or sell a portfolio
security at a time that otherwise would be favorable for it to do so or the
possible need for the Fund to sell a portfolio security at a disadvantageous
time, due to the need for the Fund to maintain "cover" or to segregate
securities in connection with hedging transactions.
    
 
LIMITATIONS ON THE PURCHASE AND SALE OF STOCK OPTIONS, OPTIONS ON INDICES, AND
STOCK AND BOND INDEX FUTURES AND OPTIONS THEREON
 
   
    Under regulations of the Commodity Exchange Act, investment companies
registered under the Investment Company Act of 1940, as amended (the Investment
Company Act), are exempt from the definition of "commodity pool operator,"
subject to compliance with certain conditions. The exemption is conditioned upon
the Fund's purchasing and selling futures contracts and options thereon for BONA
FIDE hedging transactions, except that the Fund may purchase and sell futures
and options thereon for any other purpose to the extent that the aggregate
initial margin and option premiums do not exceed 5% of the market value of the
Fund's total assets.
    
 
   
RISKS OF TRANSACTIONS IN STOCK OPTIONS
    
 
    Writing of options involves the risk that there will be no market in which
to effect a closing transaction. An exchange traded option may be closed out
only on an exchange, board of trade or other trading facility which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those exchange-traded options for which there
appears to be an active secondary market, there is no assurance that a liquid
secondary market on an exchange will exist for any particular option, or at any
particular time, and for some options no secondary market on an exchange may
exist. In such event it might not be possible to effect closing transactions in
particular exchange-traded options, with the result that the Fund would have to
exercise its options in order to realize any profit and would incur brokerage
commissions upon the exercise of call options and upon the subsequent
disposition of underlying securities acquired through the exercise of call
options or upon the purchase of underlying securities for the exercise of put
options. If the Fund as a covered call option writer is unable to effect a
closing purchase transaction in a secondary market, it will not be able to sell
the underlying security until the option expires or it delivers the underlying
security upon exercise.
 
    In the case of OTC options, it is not possible to effect a closing
transaction in the same manner as exchange-traded options because a clearing
corporation is not interposed between the buyer and seller of the option. When
the Fund writes an OTC option, it generally will be able to close out the OTC
option prior to its expiration only by entering into a closing purchase
transaction with the dealer with which the Fund originally wrote the OTC option.
Any such cancellation, if agreed to, may require the Fund to pay a premium to
the counterparty. While the Fund will enter into OTC options only with dealers
which agree to, and which are expected to be capable of, entering into closing
transactions with the Fund, there can be no assurance that the Fund will be able
to liquidate an OTC option at a favorable price at any time prior to expiration.
Until the
 
                                      B-7
<PAGE>
Fund is able to effect a closing purchase transaction in a covered OTC call
option the Fund has written, it will not be able to liquidate securities used as
cover until the option expires or is exercised or different cover is
substituted. Alternatively, the Fund could write an OTC call option to, in
effect, close an existing OTC call option or write an OTC put option to close
its position on an OTC put option. However, the Fund would remain exposed to
each counterparty's credit risk on the put or call until such option is
exercised or expires. There is no guarantee that the Fund will be able to write
put or call options, as the case may be, that would effectively close an
existing position. In the event of insolvency of the counterparty, the Fund may
be unable to liquidate an OTC option.
 
   
    The Fund may also purchase a "protective put," that is, a put option
acquired for the purpose of protecting a portfolio security from a decline in
market value. In exchange for the premium paid for the put option, the Fund
acquires the right to sell the underlying security at the exercise price of the
put regardless of the extent to which the underlying security declines in value.
The loss to the Fund is limited to the premium paid for, and transaction costs
in connection with, the put plus the initial excess, if any, of the market price
of the underlying security over the exercise price. However, if the market price
of the security underlying the put rises, the profit the Fund realizes on the
sale of the security will be reduced by the premium paid for the put option less
any amount (net of transaction costs) for which the put may be sold. Similar
principles apply to the purchase of puts on stock or bond indices in the
over-the-counter market.
    
 
   
    As discussed above, an OTC option is a direct contractual relationship with
another party. Consequently, in entering into OTC options, the Fund will be
exposed to the risk that the counterparty will default on, or be unable to
complete, due to bankruptcy or otherwise, its obligation on the option. In such
an event, the Fund may lose the benefit of the transaction. The value of an OTC
option to the Fund is dependent upon the financial viability of the
counterparty. If the Fund decides to enter into transactions in OTC options, the
investment adviser will take into account the credit quality of counterparties
in order to limit the risk of default by the counterparty.
    
 
   
    The staff of the Securities and Exchange Commission (Commission) has taken
the position that purchased OTC options and the assets used as "cover" for
written OTC options are illiquid securities unless the Fund and the counterparty
have provided for the Fund, at the Fund's election, to unwind the OTC option.
The exercise of such an option ordinarily would involve the payment by the Fund
of an amount designed to reflect the counterparty's economic loss from an early
termination, but does allow the Fund to treat the assets used as "cover" as
"liquid."
    
 
   
RISKS OF OPTIONS ON INDICES
    
 
    The Fund's purchase and sale of options on indices will be subject to risks
described above under "Risks of Transactions in Stock Options." In addition, the
distinctive characteristics of options on indices create certain risks that are
not present with stock options.
 
    Because the value of an index option depends upon movements in the level of
the index rather than the price of a particular security, whether the Fund will
realize a gain or loss on the purchase or sale of an option on an index depends
upon movements in the level of prices in the market in which the securities
comprising the index are traded generally or in an industry or market segment
rather than movements in the price of a particular security. Accordingly,
successful use by the Fund of options on indices would be subject to the
investment adviser's ability to predict correctly movements in the direction of
the market generally or of a particular industry. This requires different skills
and techniques than predicting changes in the price of individual securities.
The investment adviser currently uses such techniques in conjunction with the
management of other mutual funds.
 
    Index prices may be distorted if trading of certain securities included in
the index is interrupted. Trading in index options also may be interrupted in
certain circumstances, such as if trading were halted in a substantial number of
securities included in the index. If this occurred, the Fund would not be able
to close out options which it had purchased or written and, if restrictions on
exercise were imposed, may be unable to exercise an option it holds, which could
result in substantial losses to the Fund. It is the Fund's policy to purchase or
write options only on indices which include a number of securities sufficient to
minimize the likelihood of a trading halt in the index, such as the S&P 100 or
S&P 500 index option.
 
    Although the markets for certain index option contracts have developed
rapidly, the markets for other index options are still relatively illiquid. The
ability to establish and close out positions on such options will be subject to
the development
 
                                      B-8
<PAGE>
and maintenance of a liquid secondary market. It is not certain that this market
will develop in all index option contracts. The Fund will not purchase or sell
any index option contract unless and until, in the investment adviser's opinion,
the market for such options has developed sufficiently that the risk in
connection with these transactions is no greater than the risk in connection
with options on stocks.
 
   
SPECIAL RISKS OF WRITING CALLS ON INDICES
    
 
    Because exercises of index options are settled in cash, a call writer such
as the Fund cannot determine the amount of its settlement obligations in advance
and, unlike call writing on specific stocks, cannot provide in advance for, or
cover, its potential settlement obligations by acquiring and holding the
underlying securities. However, the Fund will write call options on indices only
under the circumstances described above under "Stock Index Options."
 
    Price movements in the Fund's portfolio probably will not correlate
precisely with movements in the level of a particular index and, therefore, the
Fund bears the risk that the price of the securities held by the Fund may not
increase as much as the index. In such an event, the Fund would bear a loss on
the call which is not completely offset by movements in the price of the Fund's
portfolio. It is also possible that the index may rise when the price of the
Fund's portfolio does not rise. If this occurred, the Fund would experience a
loss on the call which is not offset by an increase in the value of its
portfolio and might also experience a loss in its portfolio. However, because
the value of a diversified portfolio will, over time, tend to move in the same
direction as the market, movements in the value of the Fund in the opposite
direction as the market would be likely to occur for only a short period or to a
small degree.
 
    Unless the Fund has other liquid assets which are sufficient to satisfy the
exercise of a call, the Fund would be required to liquidate portfolio securities
in order to satisfy the exercise. Because an exercise must be settled within
hours after receiving the notice of exercise, if the Fund fails to anticipate an
exercise, it may have to borrow from a bank (in amounts not exceeding 20% of the
Fund's total assets) pending settlement of the sale of securities in its
portfolio and would incur interest charges thereon.
 
    When the Fund has written a call, there is also a risk that the market may
decline between the time the Fund has a call exercised against it, at a price
which is fixed as of the closing level of the index on the date of exercise, and
the time the Fund is able to sell securities in its portfolio. As with stock
options, the Fund will not learn that an index option has been exercised until
the day following the exercise date but, unlike a call on stock where the Fund
would be able to deliver the underlying securities in settlement, the Fund may
have to sell part of its portfolio in order to make settlement in cash, and the
price of such securities might decline before they can be sold. This timing risk
makes certain strategies involving more than one option substantially more risky
with index options than with stock or bond options. For example, even if an
index call which the Fund has written is "covered" by an index call held by the
Fund with the same strike price, the Fund will bear the risk that the level of
the index may decline between the close of trading on the date the exercise
notice is filed with the clearing corporation and the close of trading on the
date the Fund exercises the call it holds or the time the Fund sells the call
which in either case would occur no earlier than the day following the day the
exercise notice was filed.
 
   
SPECIAL RISKS OF PURCHASING PUTS AND CALLS ON INDICES
    
 
    If the Fund holds an index option and exercises it before final
determination of the closing index value for that day, it runs the risk that the
level of the underlying index may change before closing. If such a change causes
the exercised option to fall out-of-the-money, the Fund will be required to pay
the difference between the closing index value and the exercise price of the
option (times the applicable multiple) to the assigned writer. Although the Fund
may be able to minimize this risk by withholding exercise instructions until
just before the daily cutoff time or by selling rather than exercising an option
when the index level is close to the exercise price, it may not be possible to
eliminate this risk entirely because the cutoff times for index options may be
earlier than those fixed for other types of options and may occur before
definitive closing index values are announced.

<PAGE>
   
RISKS OF TRANSACTIONS IN OPTIONS ON STOCK AND BOND INDEX FUTURES
    
 
    There are several risks in connection with the use of options on stock and
bond index futures contracts as a hedging device. The correlation between the
price of the futures contract and the movements in the index may not be perfect.
Therefore, a correct forecast of interest rates and other factors affecting
markets for securities may still not result in a successful hedging transaction.
 
    Futures prices often are extremely volatile so successful use of options on
stock or bond index futures contracts by the Fund is also subject to the ability
of the Fund's investment adviser to predict correctly movements in the direction
of markets, changes in supply and demand, interest rates, international
political and economic policies, and other factors affecting the stock and bond
markets generally. For example, if the Fund has hedged against the possibility
of a decrease in an index which would adversely affect the price of securities
in its portfolio and the price of such securities increases instead, then the
Fund will lose part or all of the benefit of the increased value of its
securities because it will have offsetting losses in its futures positions. In
addition, in such situations, if the Fund has insufficient cash to meet daily
variation margin requirements, it may need to sell securities to meet such
requirements at a time when it is disadvantageous to do so. Such sales of
securities may be, but will not necessarily be, at increased prices which
reflect the rising market.
 
    The hours of trading of options on stock or bond index futures contracts may
not conform to the hours during which the Fund may trade the underlying
securities. To the extent the futures markets close before the securities
markets, significant price and rate movements can take place in the securities
markets that cannot be reflected in the futures markets.
 
    Options on stock and bond index futures contracts are highly leveraged and
the specific market movements of the contract underlying an option cannot be
predicted. Options on futures must be bought and sold on exchanges. Although the
exchanges provide a means of selling an option previously purchased or of
liquidating an option previously written by an offsetting purchase, there can be
no assurance that a liquid market will exist for a particular option at a
particular time. If such a market does not exist, the Fund, as the holder of an
option on futures contracts, would have to exercise the option and comply with
the margin requirements for the underlying futures contract to realize any
profit, and if the Fund were the writer of the option, its obligation would not
terminate until the option expired or the Fund was assigned an exercise notice.
 
   
FOREIGN CURRENCY FORWARD CONTRACTS
    
 
   
    The Fund may enter into foreign currency forward contracts to protect the
value of its portfolio against future changes in the level of currency exchange
rates. A forward contract on foreign currency is an obligation to purchase or
sell a specific currency at a future date, which may be any fixed number of days
agreed upon by the parties from the date of the contract at a price set on the
date of the contract. These contracts are traded in the interbank market
conducted directly between currency traders (typically large commercial banks)
and their customers. A forward contract generally has no deposit requirements,
and no commissions are charged for such trades.
    
 
   
    The Fund may not use forward contracts to generate income, although the use
of such contracts may incidentally generate income. There is no limitation on
the value of forward contracts into which the Fund may enter. However, the
Fund's dealings in forward contracts will be limited to hedging involving either
specific transactions or portfolio positions. Transaction hedging is the
purchase or sale of a forward contract with respect to specific receivables or
payables of the Fund generally arising in connection with the purchase or sale
of its portfolio securities and accruals of interest or dividends receivable and
Fund expenses. Position hedging is the sale of a foreign currency with respect
to portfolio security positions denominated or quoted in that currency or in a
different foreign currency (cross-hedge). The Fund will not speculate in forward
contracts. The Fund may not position hedge (including cross-hedges) with respect
to a particular currency for an amount greater than the aggregate market value
(determined at the time of making any sale of foreign currency) of the
securities being hedged.
    
 
   
    When the Fund enters into a contract for the purchase or sale of a security
denominated in a foreign currency, or when the Fund anticipates the receipt in a
foreign currency of dividends or interest payments on a security which it holds,
the Fund may desire to "lock in" the U.S. dollar price of the security or the
U.S. dollar equivalent of such dividend or interest payment, as the case may be.
By entering into a forward contract for a fixed amount of dollars for the
purchase or sale of the amount of foreign currency involved in the underlying
transaction, the Fund will be able to protect itself against
    
 
                                      B-10
<PAGE>
   
possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the subject foreign currency during the period between the date
on which the security is purchased or sold, or on which the dividend or interest
payment is declared, and the date on which such payments are made or received.
Additionally, when the investment adviser believes that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar, the Fund may enter into a forward contract, for a fixed amount of
dollars, to sell the amount of foreign currency approximating the value of some
or all of the portfolio securities of the Fund denominated in such foreign
currency.
    
 
   
    Since investments in foreign companies will usually involve currencies of
foreign countries, and since the Fund may hold funds in bank deposits in foreign
currencies, the value of the assets of the Fund as measured in U.S. dollars may
be affected favorably or unfavorably by changes in foreign currency rates and
exchange control regulations, and the Fund may incur costs in connection with
conversions between various currencies. The Fund will conduct its foreign
currency exchange transactions on a spot (that is, cash) basis at the spot rate
prevailing in the foreign currency exchange market, or through entering into
forward contracts to purchase or sell foreign currencies. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of the
contract. A forward contract generally has no deposit requirement, and no
commissions are charged at any stage for such trades.
    
 
   
    Forward foreign currency exchange contracts are traded in the interbank
market conducted directly between currency traders (usually large commercial
banks) and their customers. They are not traded on exchanges regulated by the
CFTC or the Commission. As a result, many of the protections afforded to
exchange participants will not be available.
    
 
    The Fund may enter into forward foreign currency exchange contracts in
several circumstances. When the Fund enters into a contract for the purchase or
sale of a security denominated in a foreign currency, or when the Fund
anticipates the receipt in a foreign currency of dividends or interest payments
on a security which it holds, the Fund may desire to "lock-in" the U.S. dollar
price of the security or the U.S. dollar equivalent of such dividend or interest
payment, as the case may be. By entering into a forward contract for a fixed
amount of dollars for the purchase or sale of the amount of foreign currency
involved in the underlying transactions, the Fund will be able to protect itself
against a possible loss resulting from an adverse change in the relationship
between the U.S. dollar and the subject foreign currency during the period
between the date on which the security is purchased or sold, or on which the
dividend or interest payment is declared, and the date on which such payments
are made or received.
 
   
    Additionally, when the investment adviser believes that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar, the Fund may enter into a forward contract for a fixed amount of
dollars, to sell the amount of foreign currency approximating the value of some
or all of the Fund's portfolio securities denominated in such foreign currency.
The precise matching of the forward contract amounts and the value of the
securities involved will not generally be possible since the future value of
securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the forward
contract is entered into and the date it matures. The projection of short-term
currency market movement is extremely difficult and the successful execution of
a short-term hedging strategy is highly uncertain. The Fund will not enter into
such forward contracts or maintain a net exposure to such contracts where the
consummation of the contracts would obligate the Fund to deliver an amount of
foreign currency in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency. Under normal circumstances,
consideration of the prospect for currency parities will be incorporated into
the long-term investment decisions made with regard to overall diversification
strategies. However, the Fund believes that it is important to have the
flexibility to enter into such forward contracts when it determines that the
best interests of the Fund will thereby be served. If the Fund enters into a
position hedging transaction, the transaction will be covered by the position
being hedged, or the Fund's Custodian will segregate cash or other liquid assets
into a segregated account of the Fund (less the value of the "covering"
positions, if any) in an amount equal to the value of the Fund's total assets
committed to the consummation of the given forward contract. The assets
segregated will be marked-to-market daily, and if the value of the securities
segregated declines, additional cash or securities will be segregated so that
the value of the account will equal the amount of the Fund's net commitments
with respect to such contracts.
    
 
                                      B-11
<PAGE>
    The Fund generally will not enter into a forward contract with a term of
greater than one year. At the maturity of a forward contract, the Fund may
either sell the portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate its contractual obligation to deliver
the foreign currency by purchasing an "offsetting" contract with the same
currency trader obligating it to purchase, on the same maturity date, the same
amount of the foreign currency.
 
    It is impossible to forecast with absolute precision the market value of a
particular portfolio security at the expiration of the contract. Accordingly, it
may be necessary for the Fund to purchase additional foreign currency on the
spot market (and bear the expense of such purchase) if the market value of the
security is less than the amount of foreign currency that the Fund is obligated
to deliver and if a decision is made to sell the security and make delivery of
the foreign currency.
 
    If the Fund retains the portfolio security and engages in an offsetting
transaction, the Fund will incur a gain or a loss (as described below) to the
extent that there has been movement in forward contract prices. Should forward
prices decline during the period between the Fund's entering into a forward
contract for the sale of a foreign currency and the date it enters into an
offsetting contract for the purchase of the foreign currency, the Fund will
realize a gain to the extent that the price of the currency it has agreed to
sell exceeds the price of the currency it has agreed to purchase. Should forward
contract prices increase, the Fund will suffer a loss to the extent that the
price of the currency it has agreed to purchase exceeds the price of the
currency it has agreed to sell.
 
   
    The Fund's dealing in foreign currency forward contracts will be limited to
the transactions described above. Of course, the Fund is not required to enter
into such transactions with regard to its foreign currency-denominated
securities. It also should be realized that this method of protecting the value
of the Fund's portfolio securities against a decline in the value of a currency
does not eliminate fluctuations in the underlying prices of the securities which
are unrelated to exchange rates. It simply establishes a rate of exchange which
one can achieve at some future point in time. Additionally, although such
contracts tend to minimize the risk of loss due to a decline in the value of the
hedged currency, at the same time, they tend to limit any potential gain which
might result should the value of such currency increase. The Fund's ability to
enter into foreign currency forward contracts may be limited by certain
requirements for qualification as a regulated investment company under the
Internal Revenue Code. See "Taxes, Dividends and Distributions."
    
 
    Although the Fund values its assets daily in terms of U.S. dollars, it does
not intend physically to convert its holdings of foreign currencies into U.S.
dollars on a daily basis. It will do so from time to time, and investors should
be aware of the costs of currency conversion. Although foreign exchange dealers
do not charge a fee for conversion, they do realize a profit based on the
difference (the spread) between the prices at which they are buying and selling
various currencies. Thus, a dealer may offer to sell a foreign currency to the
Fund at one rate, while offering a lesser rate of exchange should the Fund
desire to resell that currency to the dealer.
 
OPTIONS ON FOREIGN CURRENCIES
 
   
    The Fund is permitted to purchase and write put and call options on foreign
currencies and on futures contracts on foreign currencies traded on securities
exchanges or boards of trade (foreign and domestic) for hedging purposes in a
manner similar to that in which forward foreign currency exchange contracts and
futures contracts on foreign currencies will be employed. Options on foreign
currencies and on futures contracts on foreign currencies are similar to options
on stock, except that the Fund has the right to take or make delivery of a
specified amount of foreign currency, rather than stock.
    
 
   
    The Fund may purchase and write options to hedge the Fund's portfolio
securities denominated in foreign currencies. If there is a decline in the
dollar value of a foreign currency in which the Fund's portfolio securities are
denominated, the dollar value of such securities will decline even though the
foreign currency value remains the same. To hedge against the decline of the
foreign currency, the Fund may purchase put options on futures contracts on such
foreign currency. If the value of the foreign currency declines, the gain
realized on the put option would offset, in whole or in part, the adverse effect
such decline would have on the value of the portfolio securities. Alternatively,
the Fund may write a call option on a
    
 
                                      B-12
<PAGE>
   
futures contract on the foreign currency. If the value of the foreign currency
declines, the option would not be exercised and the decline in the value of the
portfolio securities denominated in such foreign currency would be offset in
part by the premium the Fund received for the option.
    
 
   
    If, on the other hand, the investment adviser anticipates purchasing a
foreign security and also anticipates a rise in the value of such foreign
currency (thereby increasing the cost of such security), the Fund may purchase
call options on the foreign currency. The purchase of such options could offset,
at least partially, the effects of the adverse movements of the exchange rates.
Alternatively, the Fund could write a put option on the currency and, if the
exchange rates move as anticipated, the option would expire unexercised.
    
 
    Instead of purchasing or selling futures or forward currency exchange
contracts, the Fund may attempt to accomplish similar objectives by purchasing
put or call options on currencies either on exchanges or in over-the-counter
markets or by writing put options or covered call options on currencies. A put
option gives the Fund the right to sell a currency at the exercise price until
the option expires. A call option gives the Fund the right to purchase a
currency at the exercise price until the option expires. Both options serve to
insure against adverse currency price movements in the underlying portfolio
assets designated in a given currency. Currency options traded on U.S. or other
exchanges may be subject to position limits which may limit the ability of the
Fund to fully hedge its positions by purchasing such options.
 
   
    The Fund may hedge against the risk of a decrease or increase in the U.S.
dollar value of a foreign currency denominated security which the Fund owns or
intends to acquire by purchasing or selling options contracts, futures contracts
or options thereon with respect to a foreign currency other than the foreign
currency in which such security is denominated, where the values of such
different currencies (as compared to the U.S. dollar) historically have a high
degree of positive correlation.
    
 
RISK OF TRANSACTIONS IN EXCHANGE TRADED OPTIONS
 
    An option position may be closed out only on an exchange, board of trade or
other trading facility which provides a secondary market for an option of the
same series. Although the Fund will generally purchase or write only those
options for which there appears to be an active secondary market, there is no
assurance that a liquid secondary market on an exchange will exist for any
particular option, or at any particular time, and for some options no secondary
market on an exchange or otherwise may exist. In such event it might not be
possible to effect closing transactions in particular options, with the result
that the Fund would have to exercise its options in order to realize any profits
and would incur brokerage commissions upon the exercise of call options and upon
the subsequent disposition of underlying currencies acquired through the
exercise of call options or upon the purchase of underlying currencies for the
exercise of put options. If the Fund, as a covered call option writer, is unable
to effect a closing purchase transaction in a secondary market, it will not be
able to sell the underlying currency until the option expires or it delivers the
underlying currency upon exercise.
 
   
    Reasons for the absence of a liquid secondary market on an exchange include
the following: (1) there may be insufficient trading interest in certain
options; (2) restrictions may be imposed by an exchange on opening transactions
or closing transactions or both; (3) trading halts, suspensions or other
restrictions may be imposed with respect to particular classes or series of
options; (4) unusual or unforeseen circumstances may interrupt normal operations
on an exchange; (5) the facilities of an exchange or a clearing corporation may
not at all times be adequate to handle current trading or volume; or (6) one or
more exchanges could, for economic or other reasons, decide or be compelled at
some future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that exchange (or in
the class or series of options) would cease to exist, although outstanding
options on that exchange that had been issued by a clearing corporation as a
result of trades on that exchange would continue to be exercisable in accordance
with their terms. There is no assurance that higher than anticipated trading
activity or other unforeseen events might not, at times, render certain of the
facilities of any of the clearing corporations inadequate, and thereby result in
the institution by an exchange of special procedures which may interfere with
the timely execution of customers' orders. The Fund intends to purchase and sell
only those options which are cleared by a clearinghouse whose facilities are
considered to be adequate to handle the volume of options transactions.

RISKS OF OPTIONS ON FOREIGN CURRENCIES
 
   
    Options on foreign currencies involve the currencies of two nations and,
therefore, developments in either or both countries can affect the values of
options on foreign currencies. Risks include those described above under "Risks
of Risk Management and Return Enhancement Strategies," including government
actions affecting currency valuation and the movements of currencies from one
country to another. The quantity of currency underlying option contracts
represents odd lots in a market dominated by transactions between banks; this
can mean extra transaction costs upon exercise. Options markets may be closed
while round-the-clock interbank currency markets are open. This can create price
and rate discrepancies.
    
 
RISKS OF TRANSACTIONS IN FUTURES CONTRACTS ON FOREIGN CURRENCIES
 
   
    There are several risks in connection with the use of futures contracts as a
hedging device. Due to the imperfect correlation between the price of futures
contracts and movements in the currency or group of currencies, the price of a
futures contract may move more or less than the price of the currencies being
hedged. Therefore, a correct forecast of currency rates, market trends or
international political trends by the Manager or investment adviser may still
not result in a successful hedging transaction.
    
 
   
    Although the Fund will purchase or sell futures contracts only on exchanges
where there appears to be an adequate secondary market, there is no assurance
that a liquid secondary market on an exchange will exist for any particular
contract or at any particular time. Accordingly, there can be no assurance that
it will be possible, at any particular time, to close a futures position. In the
event the Fund could not close a futures position and the value of such position
declined, the Fund would be required to continue to make daily cash payments of
variation margin. There is no guarantee that the price movements of the
portfolio securities denominated in foreign currencies will, in fact, correlate
with the price movements in the futures contracts and thus provide an offset to
losses on a futures contract.
    
 
   
    Successful use of futures contracts by the Fund is also subject to the
ability of the Fund's Manager or investment adviser to predict correctly
movements in the direction of markets and other factors affecting currencies
generally. For example, if the Fund has hedged against the possibility of an
increase in the price of securities in its portfolio and the price of such
securities increases instead, the Fund will lose part or all of the benefit of
the increased value of its securities because it will have offsetting losses in
its futures positions. In addition, in such situations, if the Fund has
insufficient cash to meet daily variation margin requirements, it may need to
sell securities to meet such requirements. Such sales of securities may be, but
will not necessarily be, at increased prices which reflect the rising market.
The Fund may have to sell securities at a time when it is disadvantageous to do
so.
    
 
    The hours of trading of futures contracts may not conform to the hours
during which the Fund may trade the underlying securities. To the extent that
the futures markets close before the securities markets, significant price and
rate movements can take place in the securities markets that cannot be reflected
in the futures markets.
 
OPTIONS ON FUTURES CONTRACTS ON FOREIGN CURRENCIES
 
   
    An option on a futures contract gives the purchaser the right, but not the
obligation, to assume a position in a futures contract (a long position if the
option is a call and a short position if the option is a put) at a specified
exercise price at any time during the option exercise period. The writer of the
option is required upon exercise to assume an offsetting futures position (a
short position if the option is a call and a long position if the option is a
put). Upon exercise of the option, the assumption of offsetting futures
positions by the writer and holder of the option will be accompanied by delivery
of the accumulated cash balance in the writer's futures margin account which
represents the amount by which the market price of the futures contract, at
exercise, exceeds, in the case of a call, or is less than, in the case of a put,
the exercise price of the option on the futures contract.
    
 
    The holder or writer of an option may terminate its position by selling or
purchasing an option of the same series. There is no guarantee that such closing
transactions can be effected.
 
                                      B-14
<PAGE>
LIMITATIONS ON PURCHASE AND SALE OF OPTIONS ON FOREIGN CURRENCIES AND FUTURES
CONTRACTS ON FOREIGN CURRENCIES
 
    The Fund will write put options on foreign currencies and futures contracts
on foreign currencies only if they are covered by segregating with the Fund's
Custodian an amount of cash or other liquid assets equal to the aggregate
exercise price of the puts.
 
    The Fund intends to engage in futures contracts and options on futures
contracts as a hedge against changes in the value of the currencies to which the
Fund is subject or to which the Fund expects to be subject in connection with
futures purchases. The Fund also intends to engage in such transactions when
they are economically appropriate for the reduction of risks inherent in the
ongoing management of the Fund.
 
POSITION LIMITS
 
    Transactions by the Fund in futures contracts and options will be subject to
limitations, if any, established by each of the exchanges, boards of trade or
other trading facilities (including NASDAQ) governing the maximum number of
options in each class which may be written or purchased by a single investor or
group of investors acting in concert, regardless of whether the options are
written on the same or different exchanges, boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of futures contracts and options which the Fund may
write or purchase may be affected by the futures contracts and options written
or purchased by other investment advisory clients of the investment adviser. An
exchange, board of trade or other trading facility may order the liquidation of
positions found to be in excess of these limits, and it may impose certain other
sanctions.
 
   
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
    
 
   
    The Fund may purchase or sell securities on a when-issued or delayed
delivery basis. When-issued or delayed delivery transactions arise when
securities are purchased or sold by the Fund with payment and delivery taking
place in the future in order to secure what is considered to be an advantageous
price and yield to the Fund at the time of entering into the transaction. The
Fund's Custodian will maintain, in a segregated account of the Fund, cash or
other liquid assets having a value equal to or greater than the Fund's purchase
commitments. The securities so purchased are subject to market fluctuation and
no interest accrues to the purchaser during the period between purchase and
settlement. At the time of delivery of the securities, the value may be more or
less than the purchase price and an increase in the percentage of the Fund's
assets committed to the purchase of securities on a when-issued or delayed
delivery basis may increase the volatility of the Fund's net asset value.
    
 
REPURCHASE AGREEMENTS
 
   
    The Fund may on occasion enter into repurchase agreements whereby the seller
agrees to repurchase that security from the Fund at a mutually agreed-upon time
and price. The period of maturity is usually quite short, possibly overnight or
a few days, although it may extend over a number of months. The resale price is
in excess of the purchase price, reflecting an agreed-upon rate of return
effective for the period of time the Fund's money is invested in the repurchase
agreement. The Fund's repurchase agreements will at all times be fully
collateralized in an amount at least equal to the resale price. The instruments
held as collateral are valued daily, and if the value of instruments declines,
the Fund will require additional collateral. If the seller defaults and the
value of the collateral securing the repurchase agreement declines, the Fund may
incur a loss. The Fund participates in a joint repurchase account with other
investment companies managed by the Manager pursuant to an order of the
Commission.
    
 
   
BORROWING
    
 
   
    The Fund may borrow up to 20% of the value of its total assets (calculated
when the loan is made) for temporary, extraordinary or emergency purposes or for
the clearance of transactions. The Fund may pledge up to 20% of its total assets
to secure these borrowings.
    
 
                                      B-15
<PAGE>
   
LENDING OF SECURITIES
    
 
   
    Consistent with applicable regulatory requirements, the Fund may lend its
portfolio securities to brokers, dealers and financial institutions, provided
that outstanding loans do not exceed in the aggregate 33% of the value of the
Fund's total assets and that the loans are callable at any time by the Fund. As
a matter of fundamental policy, the Fund will not lend more than 33% of the
value of its total assets. The loans must at all times be secured by cash or
other liquid assets or secured by an irrevocable letter of credit in favor of
the Fund in an amount equal to at least 100%, determined daily, of the market
value of the loaned securities. The collateral is segregated pursuant to
applicable regulations. During the time portfolio securities are on loan, the
borrower will pay the Fund an amount equivalent to any dividend or interest paid
on such securities and the Fund may invest the cash collateral and earn
additional income, or it may receive an agreed-upon amount of interest income
from the borrower. The advantage of such loans is that the Fund continues to
receive payments in lieu of the interest and dividends on the loaned securities,
while at the same time earning interest either directly from the borrower or on
the collateral, which will be invested in short-term obligations.
    
 
    A loan may be terminated by the borrower on one business day's notice or by
the Fund at any time. If the borrower fails to maintain the requisite amount of
collateral, the loan automatically terminates, and the Fund could use the
collateral to replace the securities while holding the borrower liable for any
excess of replacement cost over collateral. As with any extensions of credit,
there are risks of delay in recovery and in some cases loss of rights in the
collateral should the borrower of the securities fail financially. However,
these loans of portfolio securities will only be made to firms determined to be
creditworthy pursuant to procedures approved by the Board of Directors of the
Fund. On termination of the loan, the borrower is required to return the
securities to the Fund, and any gain or loss in the market price during the loan
would inure to the Fund.
 
    Since voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loan, in whole or in
part as may be appropriate, to permit the exercise of such rights if the matters
involved would have a material effect on the Fund's investment in the securities
which are the subject of the loan. The Fund will pay reasonable finders',
administrative and custodial fees in connection with a loan of its securities or
may share the interest earned on collateral with the borrower.
 
   
SEGREGATED ASSETS
    
 
   
    The Fund will mark as segregated with its Custodian, State Street Bank and
Trust Company, cash, U.S. Government securities, equity securities (including
foreign securities), debt securities or other liquid, unencumbered assets equal
in value to its obligations in respect of potentially leveraged transactions.
These include forward contracts, when-issued and delayed delivery securities,
futures contracts, written options and options on futures contracts (unless
otherwise covered). If collateralized or otherwise covered, in accordance with
Commission guidelines, these will not be deemed to be senior securities. The
assets deposited in the segregated account will be marked-to-market daily.
    
 
ILLIQUID SECURITIES
 
   
    The Fund may hold up to 15% of its net assets in illiquid securities,
including repurchase agreements which have a maturity of longer than seven days,
securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable in securities markets
either within or outside of the United States. Repurchase agreements subject to
demand are deemed to have a maturity equal to the applicable notice period.
    
 
   
    Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (the Securities Act),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the Securities Act are referred to as private placements or
restricted securities and are purchased directly from the issuer or in the
secondary market. Mutual funds do not typically hold a significant amount of
restricted or other illiquid securities because of the potential for delays on
resale and uncertainty in valuation. Limitations on resale may have an adverse
effect on the marketability of portfolio securities and a mutual fund might be
unable to dispose of restricted or other illiquid securities promptly or at
reasonable prices and might thereby experience
    
 
                                      B-16
<PAGE>
difficulty satisfying redemptions within seven days. A mutual fund might also
have to register such restricted securities in order to dispose of them,
resulting in additional expense and delay. Adverse market conditions could
impede such a public offering of securities.
 
    In recent years, however, a large institutional market has developed for
certain securities that are not registered under the Securities Act including
repurchase agreements, commercial paper, foreign securities, municipal
securities, convertible securities and corporate bonds and notes. Institutional
investors depend on an efficient institutional market in which the unregistered
security can be readily resold or on an issuer's ability to honor a demand for
repayment. The fact that there are contractual or legal restrictions on resale
to the general public or to certain institutions may not be indicative of the
liquidity of such investments.
 
    Rule 144A under the Securities Act allows for a broader institutional
trading market for securities otherwise subject to restriction on resale to the
general public. Rule 144A establishes a "safe harbor" from the registration
requirements of the Securities Act for resales of certain securities to
qualified institutional buyers. The investment adviser anticipates that the
market for certain restricted securities such as institutional commercial paper
and foreign previously government-owned utility company securities will expand
further as a result of this new regulation and the development of automated
systems for the trading, clearance and settlement of unregistered securities of
domestic and foreign issuers, such as the PORTAL System sponsored by the
National Association of Securities Dealers, Inc.
 
   
    Restricted securities eligible for resale pursuant to Rule 144A under the
Securities Act and privately placed commercial paper for which there is a
readily available market are treated as liquid only when deemed liquid under
procedures established by the Directors. The Fund's investment in Rule 144A
securities could have the effect of increasing illiquidity to the extent that
qualified institutional buyers become, for a limited time, uninterested in
purchasing Rule 144A securities. The investment adviser will monitor the
liquidity of such restricted securities subject to the supervision of the Board
of Directors. In reaching liquidity decisions, the investment adviser will
consider, among others, the following factors: (1) the frequency of trades and
quotes for the security; (2) the number of dealers wishing to purchase or sell
the security and the number of other potential purchasers; (3) dealer
undertakings to make a market in the security; and (4) the nature of the
security and the nature of the marketplace trades (for example, the time needed
to dispose of the security, the method of soliciting offers and the mechanics of
the transfer). In addition, in order for commercial paper that is issued in
reliance on Section 4(2) of the Securities Act to be considered liquid, (a) it
must be rated in one of the two highest rating categories by at least two
nationally recognized statistical rating organizations (NRSRO), or if only one
NRSRO rates the securities, by that NRSRO, or, if unrated, be of comparable
quality in the view of the investment adviser; and (b) it must not be "traded
flat" (that is, without accrued interest) or in default as to principal or
interest. Repurchase agreements subject to demand are deemed to have a maturity
equal to the notice period.
    
 
   
(D)  DEFENSIVE STRATEGY AND SHORT-TERM INVESTMENTS
    
 
   
    When conditions dictate a defensive strategy, or pending investment of
proceeds from sales of the Fund's shares, the Fund may invest in money market
instruments, including commercial paper of domestic corporations, certificates
of deposit, bankers' acceptances and other obligations of domestic banks
(including foreign branches), and obligations issued or guaranteed by the U.S.
Government, its instrumentalities or its agencies. Investments in foreign
branches of domestic banks may be subject to certain risks, including future
political and economic developments, the possible imposition of withholding
taxes on interest income, the seizure or nationalization of foreign deposits and
foreign exchange controls or other restrictions. The Fund may also invest in
short-term municipal obligations, such as tax, bond and revenue anticipation
notes, construction loan and project financing notes and tax-exempt commercial
paper. When cash may be available only for a few days, it may be invested by the
Fund in repurchase agreements until such time as it may otherwise be invested or
used for payment of obligations of the Fund. See "Repurchase Agreements" above.
    
 
   
(E)  PORTFOLIO TURNOVER
    
 
   
    The Fund expects that its portfolio turnover rate may exceed 100%, although
such rate is not expected to exceed 200%. The portfolio's turnover rate is
computed by dividing the lesser of portfolio purchases or sales (excluding all
    
 
                                      B-17
<PAGE>
   
securities whose maturities at acquisition were one year or less) by the average
value of the portfolio. High portfolio turnover (100% or more) involves
correspondingly greater brokerage commissions and other transaction costs, which
are borne directly by the Fund.
    
 
                            INVESTMENT RESTRICTIONS
 
   
    The following restrictions are fundamental policies. Fundamental policies
are those which cannot be changed without the approval of the holders of a
majority of the Fund's outstanding voting securities. A "majority of the Fund's
outstanding voting securities," when used in this Statement of Additional
Information, means the lesser of (1) 67% of the voting shares represented at a
meeting at which more than 50% of the outstanding voting shares are present in
person or represented by proxy or (2) more than 50% of the outstanding voting
shares.
    
 
    The Fund may not:
 
     1. Purchase any security (other than obligations of the U.S. Government,
its agencies, or instrumentalities) if as a result with respect to 75% of the
Fund's total assets, more than 5% of the Fund's total assets (taken at current
value) would then be invested in securities of a single issuer; the Fund will
concentrate its investments in utility stocks as described under "Investment
Objective and Policies."
 
     2. Purchase securities on margin (but the Fund may obtain such short-term
credits as may be necessary for the clearance of transactions); the deposit or
payment by the Fund of initial or maintenance margin in connection with options,
futures contracts, options on futures contracts, forward foreign currency
exchange contracts or options on currencies is not considered the purchase of a
security on margin.
 
     3. Make short sales of securities or maintain a short position, unless at
all times when a short position is open it owns an equal amount of such
securities or securities convertible into or exchangeable, without payment of
any further consideration, for securities of the same issue as, and equal in
amount to, the securities sold short, and unless not more than 25% of the Fund's
net assets (taken at current value) is held as collateral for such sales at any
one time.
 
     4. Issue senior securities, borrow money or pledge its assets, except that
the Fund may borrow up to 20% of the value of its total assets (calculated when
the loan is made) for temporary, extraordinary or emergency purposes or for the
clearance of transactions. The Fund may pledge up to 20% of the value of its
total assets to secure such borrowings. For purposes of this restriction,
obligations of the Fund to Directors pursuant to deferred compensation
arrangements, the purchase and sale of securities on a when-issued or delayed
delivery basis, the purchase and sale of options, futures contracts, options on
futures contracts, forward foreign currency exchange contracts and options on
currencies and collateral arrangements with respect to the purchase and sale of
options, futures contracts, options on futures contracts, forward foreign
currency exchange contracts and options on currencies are not deemed to be the
issuance of a senior security or the pledge of assets.
 
     5. Purchase any security if as a result the Fund would then hold more than
10% of the outstanding voting securities of an issuer.
 
     6. Purchase any security if as a result the Fund would then have more than
5% of its total assets (taken at current value) invested in securities of
companies (including predecessors) less than three years old.
 
     7. Buy or sell commodities or commodity contracts, or real estate or
interests in real estate, except that the Fund may purchase and sell options,
futures contracts, options on futures contracts, forward foreign currency
exchange contracts and options on currencies and securities which are secured by
real estate and securities of companies which invest or deal in real estate.
 
     8. Act as underwriter except to the extent that, in connection with the
disposition of portfolio securities, it may be deemed to be an underwriter under
certain federal securities laws.
 
     9. Make investments for the purpose of exercising control or management.
 
                                      B-18
<PAGE>
    10. Invest in securities of other investment companies, except by purchases
in the open market involving only customary brokerage commissions and as a
result of which not more than 5% of its total assets (taken at current value)
would be invested in such securities, or except as part of a merger,
consolidation or other acquisition.
 
    11. Invest in interests in oil, gas or other mineral exploration or
development programs, although it may invest in the common stocks of companies
which invest in or sponsor such programs.
 
   
    12. Make loans, except through (i) the purchase of bonds, debentures,
commercial paper, corporate notes and similar evidences of indebtedness of a
type commonly sold privately to financial institutions, (ii) the lending of its
portfolio securities, as described under "Description of the Fund, Its
Investments and Risks--Lending of Securities" and (iii) repurchase agreements.
(The purchase of a portion of an issue of securities described under (i) above
distributed publicly, whether or not the purchase is made on the original
issuance, is not considered the making of a loan.)
    
 
    Whenever any fundamental investment policy or investment restriction states
a maximum percentage of the Fund's assets, it is intended that if the percentage
limitation is met at the time the investment is made, a later change in
percentage resulting from changing total or net asset values will not be
considered a violation of such policy. However, in the event that the Fund's
asset coverage for borrowings falls below 300%, the Fund will take prompt action
to reduce its borrowings, as required by applicable law.
 
   
    The Fund's policy with respect to put and call options is not a fundamental
policy and may be changed without shareholder approval.
    
 
   
    The Office of Public Utility Regulation of the SEC has advised The
Prudential Insurance Company of America and its subsidiaries (Prudential) that
the Office would not recommend enforcement action with respect to the purchase
by Prudential of securities of "public utility companies" as defined by the
Public Utility Holding Company Act of 1935 in Prudential's capacity as owner or
manager of securities on the conditions that (1) the aggregate voting securities
of public utility companies held by accounts owned or managed by Prudential,
including the Fund, will be less than 10% of the outstanding voting securities
of any public utility company and (2) Prudential will not attempt to control any
public utility company, other than through the exercise of rights associated
with stock ownership (including director representation). Accordingly, it is a
policy of the Fund, which may be changed without shareholder approval, not to
purchase any voting security of any public utility company if, as a result, the
Fund, along with other accounts owned or managed by Prudential, would then hold
10% or more of the outstanding voting securities of such company.

policy. The Directors also review the actions of the Fund's officers, who
conduct and supervise the daily business operations of the Fund.
    
 
   
    Directors and officers of the Fund are also trustees, directors and officers
of some or all of the other investment companies distributed by Prudential
Investment Management Services LLC.
    
 
   
    The Directors have adopted a retirement policy which calls for the
retirement of Directors on December 31 of the year in which they reach the age
of 72, except that retirement is being phased in for Directors who are age 68 or
older as of December 31, 1993. Under this phase-in provision, Mr. Beach is
scheduled to retire on December 31, 1999.
    
 
   
    Pursuant to the Management Agreement with the Fund, the Manager pays all
compensation of officers and employees of the Fund as well as the fees and
expenses of all Directors of the Fund who are affiliated persons of the Manager.
The Fund pays each of its Directors who is not an affiliated person of PIFM
annual compensation of [$5,000], in addition to certain out-of-pocket expenses.
The amount of annual compensation paid each Director may change as a result of
the introduction of additional funds on whose Boards the Director may be asked
to serve.
    
 
   
    Directors may receive their Directors' fees pursuant to a deferred fee
agreement with the Fund. Under the terms of such agreement, the Fund accrues
daily the amount of Directors' fees which accrue interest at a rate equivalent
to the prevailing rate applicable to 90-day U.S. Treasury bills at the beginning
of each calendar quarter or, pursuant to a Commission exemptive order, at the
daily rate of return of the Fund. Payment of the interest so accrued is also
deferred and accruals become payable at the option of the Director. The Fund's
obligation to make payments of deferred Directors' fees, together with interest
thereon, is a general obligation of the Fund.
    
 
   
    The following table sets forth the aggregate compensation paid by the Fund
to the Directors who are not affiliated with the Manager for the fiscal year
ended December 31, 1998 and the aggregate compensation paid to such Directors
for service on the Fund's Board and the boards of all other investment companies
managed by PIFM (Fund Complex) for the calendar year ended December 31, 1998.

                     INVESTMENT ADVISORY AND OTHER SERVICES
    
 
   
(A) MANAGER AND INVESTMENT ADVISER
    
 
   
    The manager of the Fund is Prudential Investments Fund Management LLC (PIFM
or the Manager), Gateway Center Three, 100 Mulberry Street, Newark, New Jersey
07102-4077. PIFM serves as manager to all of the other investment companies
that, together with the Fund, comprise the Prudential Mutual Funds. See "How the
Fund Is Managed-- Manager" in the Prospectus. As of January 31, 1999, PIFM
managed and/or administered open-end and closed-end management investment
companies with assets of approximately $ billion. According to the Investment
Company Institute, as of November 30, 1998, the Prudential Mutual Funds were the
 th largest family of mutual funds in the United States.
    
 
   
    PIFM is a subsidiary of Prudential Securities and The Prudential Insurance
Company of America (Prudential). Prudential Mutual Fund Services LLC (PMFS or
the Transfer Agent), a wholly-owned subsidiary of PIFM, serves as the transfer
agent for the Prudential Mutual Funds and, in addition, provides customer
service, recordkeeping and management and administration services to qualified
plans.
    
 
    Pursuant to the Management Agreement with the Fund (the Management
Agreement), PIFM, subject to the supervision of the Fund's Board of Directors
and in conformity with the stated policies of the Fund, manages both the
investment operations of the Fund and the composition of the Fund's portfolio,
including the purchase, retention, disposition and loan of securities. In
connection therewith, PIFM is obligated to keep certain books and records of the
Fund. PIFM also administers the Fund's corporate affairs and, in connection
therewith, furnishes the Fund with office facilities, together with those
ordinary clerical and bookkeeping services which are not being furnished by
State Street Bank and Trust Company, the Fund's custodian, and PMFS, the Fund's
transfer and dividend disbursing agent. The management services of PIFM for the
Fund are not exclusive under the terms of the Management Agreement and PIFM is
free to, and does, render management services to others.
 
   
    For its services, PIFM receives, pursuant to the Management Agreement, a fee
at an annual rate of .60 of 1% of the Fund's average daily net assets up to and
including $250 million, .50 of 1% of the next $500 million, .45 of 1% of the
next $750 million, .40 of 1% of the next $500 million, .35 of 1% of the next $2
billion, .325 of 1% of the next $2 billion and .30 of 1% of average daily net
assets in excess of $6 billion. The fee is computed daily and payable monthly.
The Management Agreement also provides that, in the event the expenses of the
Fund (including the fees of PIFM, but excluding interest, taxes, brokerage
commissions, distribution fees and litigation and indemnification expenses and
other extraordinary expenses not incurred in the ordinary course of the Fund's
business) for any fiscal year exceed the lowest applicable annual expense
limitation established and enforced pursuant to the statutes or regulations of
any jurisdiction in which the Fund's shares are qualified for offer and sale,
the compensation due PIFM will be reduced by the amount of such excess. No
jurisdiction currently limits the Fund's expenses.

    The Management Agreement provides that PIFM will not be liable for any error
of judgment or for any loss suffered by the Fund in connection with the matters
to which the Management Agreement relates, except a loss resulting from willful
misfeasance, bad faith, gross negligence or reckless disregard of duty. The
Management Agreement provides that it will terminate automatically if assigned,
and that it may be terminated without penalty by either party upon not more than
60 days' nor less than 30 days' written notice. The Management Agreement will
continue in effect for a period of more than two years from the date of
execution only so long as such continuance is specifically approved at least
annually in conformity with the Investment Company Act.
    
 
   
    For the years ended December 31, 1998, 1997 and 1996, the Fund paid
management fees to PIFM of $      , $17,370,271 and $16,378,451, respectively.
    
 
   
    PIFM has entered into the Subadvisory Agreement with PI, a wholly-owned
subsidiary of Prudential. The Subadvisory Agreement provides that the Subadviser
will furnish investment advisory services in connection with the management of
the Fund. In connection therewith, the Subadviser is obligated to keep certain
books and records of the Fund. PIFM continues to have responsibility for all
investment advisory services pursuant to the Management Agreement and supervises
the Subadviser's performance of such services. The Subadviser is reimbursed by
PIFM for the reasonable costs and expenses incurred by the Subadviser in
furnishing those services.
    
 
   
    The Subadvisory Agreement provides that it will terminate in the event of
its assignment (as defined in the Investment Company Act) or upon the
termination of the Management Agreement. The Subadvisory Agreement may be
terminated by the Fund, PIFM or the Subadviser upon not more than 60 days', nor
less than 30 days', written notice. The Subadvisory Agreement provides that it
will continue in effect for a period of more than two years from its execution
only so long as such continuance is specifically approved at least annually in
accordance with the requirements of the Investment Company Act.

(B) PRINCIPAL UNDERWRITER, DISTRIBUTOR AND RULE 12B-1 PLANS
    
 
   
    Prudential Investment Management Services LLC (PIMS or the Distributor),
Gateway Center Three, 100 Mulberry Street, Newark, New Jersey 07102-4077, acts
as the distributor of the shares of the Fund. Prior to June 1, 1998, Prudential
Securities Incorporated (Prudential Securities) was the Fund's distributor. PIMS
and Prudential Securities are subsidiaries of Prudential.
    
 
   
    Pursuant to separate Distribution and Service Plans (the Class A Plan, the
Class B Plan and the Class C Plan, collectively, the Plans) adopted by the Fund
under Rule 12b-1 under the Investment Company Act and a distribution agreement
(the Distribution Agreement), the Distributor incurs the expenses of
distributing the Fund's Class A, Class B and Class C shares. The Distributor
also incurs the expenses of distributing the Fund's Class Z shares under the
Distribution Agreement, none of which are reimbursed by or paid for by the Fund.
See "How the Fund is Managed--Distributor" in the Prospectus.
    
 
   
    The expenses incurred under the Plans include commissions and account
servicing fees paid to, or on account of, brokers or financial institutions
which have entered into agreements with the Distributor, advertising expenses,
the cost of printing and mailing prospectuses to potential investors and
indirect and overhead costs of the Distributor associated with the sale of Fund
shares, including lease, utility, communications and sales promotion expenses.
The distribution and/or service fees may also be used by brokers to compensate
on a continuing basis brokers in consideration for the distribution, marketing,
administrative and other services and activities provided by brokers with
respect to the promotion of the sale of the Fund's shares and the maintenance of
related shareholder accounts.
    
 
   
    Under the Plans, the Fund is obligated to pay distribution and/or service
fees to the Distributor as compensation for its distribution and service
activities, not as reimbursement for specific expenses incurred. If the
Distributor's expenses exceed its distribution and service fees, the Fund will
not be obligated to pay any additional expenses. If the Distributor's expenses
are less than such distribution and service fees, it will retain its full fees
and realize a profit.
    
 
   
    The distribution and/or service fees may also be used by the Distributor to
compensate on a continuing basis brokers in consideration for the distribution,
marketing, administrative and other services and activities provided by brokers
with respect to the promotion of the sale of the Fund's shares and the
maintenance of related shareholder accounts.
    
 
   
    CLASS A PLAN. Under the Class A Plan, the Fund may pay the Distributor for
its distribution-related activities with respect to Class A shares at an annual
rate of up to .30 of 1% of the average daily net assets of the Class A shares.
The Class A Plan provides that (1) up to .25 of 1% of the average daily net
assets of the Class A shares may be used to pay for personal service and/or the
maintenance of shareholder accounts (service fee) and (2) total distribution
fees (including the service fee of .25 of 1%) may not exceed .30 of 1%. The
Distributor has voluntarily limited its distribution-related fees payable under
the Class A Plan to .25 of 1% of the average daily net assets of the Class A
shares. This voluntary waiver may be terminated at any time without notice.
    
 
   
    For the fiscal year ended December 31, 1998, the Distributor and Prudential
Securities received payments of $      and $      , respectively, under the
Class A Plan and spent approximately $    and $    , respectively, in
distributing the Fund's shares. This amount was primarily expended for payment
of account servicing fees to financial advisers and other persons who sell Class
A shares. For the fiscal year ended December 31, 1998, the Distributor and
Prudential Securities also received approximately $    and $      ,
respectively, in initial sales charges.
    
 
   
    CLASS B AND CLASS C PLANS. Under the Class B and Class C Plans, the Fund
pays the Distributor for its distribution-related activities with respect to
Class B and Class C shares at an annual rate of up to 1% of the average daily
net assets of each of the Class B and Class C shares. The Class B Plan provides
that (1) up to .25 of 1% of the average daily net assets of the Class B shares
may be paid as a service fee and (2) up to .75 of 1% (not including the service
fee) of the average daily net assets of the Class B shares (asset-based sales
charge) may be used as reimbursement for distribution-related expenses with
respect to the Class B shares. The Class C Plan provides that (1) up to .25 of
1% of the average daily net assets of the Class C shares may be paid as a
service fee for providing personal service and/or maintaining shareholder
accounts and (2) up to .75 of 1% of the average daily net assets of the Class C
shares may be paid for distribution-related
    
 
                                      B-26
<PAGE>
   
expenses with respect to Class C shares. The service fee (.25 of 1% of average
daily net assets) is used to pay for personal service and/or the maintenance of
shareholder accounts. The Distributor also receives contingent deferred sales
charges from certain redeeming shareholders.
    
 
   
    CLASS B PLAN. For the fiscal year ended December 31, 1998, the Distributor
and Prudential Securities received $    and $     , respectively, from the Fund
under the Class B Plan and spent approximately $    and $     , respectively, in
distributing the Fund's Class B shares. It is estimated that of the latter total
amount, approximately   % ($      ) was spent on printing and mailing of
prospectuses to other than current shareholders;   % ($      ) on compensation
to broker-dealers for commissions to representatives and other expenses,
including an allocation on account of overhead and other branch office
distribution-related expenses, incurred by it for distribution of Fund shares;
and   % ($      ) on the aggregate of (1) payments of commissions and account
servicing fees to financial advisers (  % or $      ) and (2) an allocation of
overhead and other branch office distribution-related expenses (  % or $      ).
The term "overhead and other branch office distribution-related expenses"
represents (a) the expenses of operating Prudential Securities' and Pruco
Securities Corporation's (Prusec's) branch offices in connection with the sale
of Fund shares, including lease costs, the salaries and employee benefits of
operations and sales support personnel, utility costs, communications costs and
the costs of stationery and supplies, (b) the costs of client sales seminars,
(c) expenses of mutual fund sales coordinators to promote the sale of Fund
shares, and (d) other incidental expenses relating to branch promotion of Fund
sales.
    
 
   
    The Distributor (and Prudential Securities as its predecessor) also receives
the proceeds of contingent deferred sales charges paid by holders of Class B
shares upon certain redemptions of Class B shares. For the fiscal year ended
December 31, 1998, the Distributor and Prudential Securities received
approximately $      and $      , respectively, in contingent deferred sales
charges attributable to Class B shares.
    
 
   
    CLASS C PLAN. For the fiscal year ended December 31, 1998, the Distributor
and Prudential Securities received $    and $      , respectively, under the
Class C Plan and spent approximately $    and $      , respectively, in
distributing Class C shares. It is estimated that of the latter total amount,
approximately   % ($    ) was spent on printing and mailing of prospectuses to
other than current shareholders;    % ($     ) on compensation to broker-dealers
for commissions to representatives and other expenses, including an allocation
of overhead and other branch office distribution-related expenses, incurred for
distribution of Fund shares; and    % ($     ) on the aggregate of (1) payments
of commissions and account servicing fees to financial advisers (   % or
$      ) and (2) an allocation of overhead and other branch office
distribution-related expenses for payments of related expenses (   % or
$      ). The Distributor (and Prudential Securities as its predecessor) also
receives the proceeds of contingent deferred sales charges paid by investors
upon certain redemptions of Class C shares. For the fiscal year ended December
31, 1998, the Distributor and Prudential Securities received approximately $
and $      , respectively, in contingent deferred sales charges attributable to
Class C shares.
    
 
   
    Distribution expenses attributable to the sale of Class A, Class B and Class
C shares of the Fund are allocated to each such class based upon the ratio of
sales of each such class to the sales of Class A, Class B and Class C shares of
the Fund other than expenses allocable to a particular class. The distribution
fee and sales charge of one class will not be used to subsidize the sale of
another class.
    
 
   
    The Class A, Class B and Class C Plans continue in effect from year to year,
provided that each such continuance is approved at least annually by a vote of
the Directors who are not interested persons of the Fund and who have no direct
or indirect financial interest in the Class A, Class B and Class C Plan or in
any agreement related to the Plans (Rule 12b-1 Directors), cast in person at a
meeting called for the purpose of voting on such continuance. A Plan may be
terminated at any time, without penalty, by the vote of a majority of the Rule
12b-1 Directors or by the vote of the holders of a majority of the outstanding
shares of the applicable class of the Fund on not more than 30 days' written
notice to any other party to the Plan. The Plans may not be amended to increase
materially the amounts to be spent for the services described therein without
approval by the shareholders of the applicable class (by both Class A and Class
B shareholders, voting separately, in the case of material amendments to the
Class A Plan), and all material amendments are required to be approved by the
Board of Directors in the manner described above. Each Plan will automatically
terminate in the event of its assignment. The Fund will not be contractually
obligated to pay expenses incurred under any Plan if it is terminated or not
continued.
    
 
                                      B-27
<PAGE>
    Pursuant to each Plan, the Board of Directors will review at least quarterly
a written report of the distribution expenses incurred on behalf of each class
of shares of the Fund by the Distributor. The report includes an itemization of
the distribution expenses and the purposes of such expenditures. In addition, as
long as the Plans remain in effect, the selection and nomination of the Rule
12b-1 Directors shall be committed to the Rule 12b-1 Directors.
 
   
    Pursuant to the Distribution Agreement, the Fund has agreed to indemnify the
Distributor to the extent permitted by applicable law against certain
liabilities under federal securities laws.
    
 
   
    In addition to distribution and service fees paid by the Fund under the
Class A, Class B and Class C Plans, the Manager (or one of its affiliates) may
make payments to dealers (including Prudential Securities) and other persons
which distribute shares of the Fund (including Class Z shares). Such payments
may be calculated by reference to the net asset value of shares sold by such
persons or otherwise.
    
 
   
    PIFM may from time to time waive all or a portion of its management fee and
subsidize all or a portion of the operating expenses of the Fund. In addition,
the Distributor has waived a portion of its distribution fees for the Class A
shares as described above. Fee waivers and subsidies will increase the Fund's
total return. These voluntary waivers may be terminated at any time without
notice. See "Performance Information."
    
 
   
    NASD MAXIMUM SALES CHARGE RULE. Pursuant to rules of the NASD, the
Distributor is required to limit aggregate initial sales charges, deferred sales
charges and asset-based sales charges to 6.25% of total gross sales of each
class of shares. Interest charges on unreimbursed distribution expenses equal to
the prime rate plus one percent per annum may be added to the 6.25% limitation.
Sales from the reinvestment of dividends and distributions are not included in
the calculation of the 6.25% limitation. The annual asset-based sales charge on
Class B shares of the Fund may not exceed .75 of 1% per class. The 6.25%
limitation applies to each class of the Fund rather than on a per shareholder
basis. If aggregate sales charges were to exceed 6.25% of total gross sales of
any class, all sales charges on shares of that class would be suspended.

                    BROKERAGE ALLOCATION AND OTHER PRACTICES
    
 
    The Manager is responsible for decisions to buy and sell securities for the
Fund, the selection of brokers and dealers to effect the transactions and the
negotiation of brokerage commissions, if any. The term "Manager" as used in this
section includes the Subadviser. Purchases and sales of securities on a
securities exchange are effected through brokers who charge a commission for
their services. Orders may be directed to any broker including, to the extent
and in the manner permitted by applicable law, Prudential Securities and its
affiliates. Brokerage commissions on United States securities, options and
futures exchanges or boards of trade are subject to negotiation between the
Manager and the broker or futures commission merchant.
 
                                      B-28
<PAGE>
   
    In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own account without a stated
commission, although the price of the security usually includes a profit to the
dealer. In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid. The Fund will not deal with Prudential
Securities or any affiliate in any transaction in which Prudential Securities or
any affilate acts as principal, except in accordance with rules of the
Commission. Thus it will not deal in the over-the-counter market with Prudential
Securities acting as market maker, and it will not execute a negotiated trade
with Prudential Securities if execution involves Prudential Securities acting as
principal with respect to any part of the Fund's order.
    
 
   
    In placing orders for portfolio securities of the Fund, the Manager's
overriding objective is to obtain the best possible combination of price and
efficient execution. The Manager seeks to effect each transaction at a price and
commission that provides the most favorable total cost or proceeds reasonably
attainable in the circumstances. The factors that the Manager may consider in
selecting a particular broker, dealer or futures commission merchant (firms) are
the Manager's knowledge of negotiated commission rates currently available and
other current transaction costs; the nature of the portfolio transaction; the
size of the transaction; the desired timing of the trade; the activity existing
and expected in the market for the particular transaction; confidentiality; the
execution, clearance and settlement capabilities of the firms; the availability
of research and research related services provided through such firms; the
Manager's knowledge of the financial stability of the firms; the Manager's
knowledge of actual or apparent operational problems of firms; and the amount of
capital, if any, that would be contributed by firms executing the transaction.
Given these factors, the Fund may pay transaction costs in excess of that which
another firm might have charged for effecting the same transaction.
    
 
   
    When the Manager selects a firm that executes orders or is a party to
portfolio transactions, relevant factors taken into consideration are whether
that firm has furnished research and research related products and/or services,
such as research reports, research compilations, statistical and economic data,
computer data bases, quotation equipment and services, research oriented
computer-software, hardware and services, reports concerning the performance of
accounts, valuations of securities, investment related periodicals, investment
seminars and other economic services and consultants. Such services are used in
connection with some or all of the Manager's investment activities; some of such
services, obtained in connection with the execution of transactions for one
investment account, may be used in managing other accounts, and not all of these
services may be used in connection with the Fund.
    
 
   
    The Manager maintains an internal allocation procedure to identify those
firms who have provided it with research and research related products and/or
services, and the amount that was provided, and to endeavor to direct sufficient
commissions to them to ensure the continued receipt of those services that the
Manager believes provides a benefit to the Fund and its other clients. The
Manager makes a good faith determination that the research and/or services is
reasonable in light of the type of service provided and the price and execution
of the related portfolio transactions.
    
 
   
    When the Manager deems the purchase or sale of equities to be in the best
interests of the Fund or its other clients, including Prudential, the Manager
may, but is under no obligation to, aggregate the transactions in order to
obtain the most favorable price or lower brokerage commissions and efficient
execution. In such event, allocation of the transactions, as well as the
expenses incurred in the transaction, will be made by the Manager in the manner
it considers to be most equitable and consistent with its fiduciary obligations
to its clients. The allocation of orders among firms and dealers and the
commission rates paid are reviewed periodically by the Fund's Board of
Directors. Portfolio securities may not be purchased from any underwriting or
selling syndicate of which Prudential Securities or any affiliate, during the
existence of the syndicate, is a principal underwriter (as defined in the
Investment Company Act), except in accordance with rules of the Commission. This
limitation, in the opinion of the Fund, will not significantly affect the Fund's
ability to pursue its present investment objective. However, in the future in
other circumstances, the Fund may be at a disadvantage because of this
limitation in comparison to other funds with similar objectives but not subject
to such limitations.
    
 
   
    Subject to the above considerations, the Manager may use Prudential
Securities as a broker or futures commission merchant for the Fund. In order for
Prudential Securities (or any affiliate) to effect any portfolio transactions
for the Fund, the commissions, fees or other remuneration received by Prudential
Securities (or any affiliate) must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other firms in connection with
comparable transactions involving similar securities being purchased or sold on
a securities exchange during a comparable period of
    
 
                                      B-29
<PAGE>
   
time. This standard would allow Prudential Securities (or any affiliate) to
receive no more than the remuneration which would be expected to be received by
an unaffiliated firm in a commensurate arm's-length transaction. Furthermore,
the Board of Directors of the Fund, including a majority of the non-interested
Directors, has adopted procedures which are reasonably designed to provide that
any commissions, fees or other remuneration paid to Prudential Securities (or
any affiliate) are consistent with the foregoing standard. In accordance with
Section 11(a) of the Securities Exchange Act of 1934, as amended, Prudential
Securities may not retain compensation for effecting transactions on a national
securities exchange for the Fund unless the Fund has expressly authorized the
retention of such compensation. Prudential Securities must furnish to the Fund
at least annually a statement setting forth the total amount of all compensation
retained by Prudential Securities from transactions effected for the Fund during
the applicable period. Brokerage transactions with Prudential Securities (or any
affiliate) are also subject to such fiduciary standards as may be imposed upon
Prudential Securities (or such affiliate) by applicable law.
    
 
    Transactions in options by the Fund will be subject to limitations
established by each of the exchanges governing the maximum number of options
which may be written or held by a single investor or group of investors acting
in concert, regardless of whether the options are written or held on the same or
different exchanges or are written or held in one or more accounts or through
one or more brokers. Thus, the number of options which the Fund may write or
hold may be affected by options written or held by the Manager and other
investment advisory clients of the Manager. An exchange may order the
liquidation of positions found to be in excess of these limits, and it may
impose certain other sanctions.

    The Fund effected approximately    % of the total dollar amount of its
transactions involving the payment of commissions through Prudential Securities
during the year ended December 31, 1998. Of the total brokerage commissions paid
during that period, $       (    %) were paid to firms which provide research,
statistical or other services to PI. PIFM has not separately identified the
portion of such brokerage commissions as applicable to the provision of such
research, statistical or other services.
    
 
   
    The Fund is required to disclose its holdings of securities of its regular
brokers and dealers (as defined under Rule 10b-1 of the Investment Company Act)
and their parents at December 31, 1998. As of December 31, 1998, the Fund held
securities of                     in the amount of $      .
    
 
   
               CAPITAL SHARES, OTHER SECURITIES AND ORGANIZATION
    
 
   
    The Fund is authorized to issue 2 billion shares of common stock, $.01 par
value per share divided into four classes, designated Class A, Class B, Class C
and Class Z shares, consisting of 500 million shares of Class A common stock,
700 million shares of Class B common stock, 400 million shares of Class C common
stock and 400 million shares of Class Z common stock. Each class of par value
shares represents an interest in the same assets of the Fund and is identical in
all respects except that (1) each class is subject to different sales charges
and distribution and/or service fees (except for Class Z shares, which are not
subject to any sales charges and distribution and/or service fees), which may
affect performance, (2) each class has exclusive voting rights on any matter
submitted to shareholders that relates solely to its arrangement and has
separate voting rights on any matter submitted to shareholders in which the
interests of one class differ from the interests of any other class, (3) each
class has a different exchange privilege, (4) only Class B shares have a
conversion feature and (5) Class Z shares are offered exclusively for sale to a
limited group of investors. In accordance with the Fund's Articles of
Incorporation, the Directors may authorize the creation of additional series and
classes within such series, with such preferences, privileges, limitations and
voting and dividend rights as the Directors may determine. The voting rights of
the shareholders of a series or class can be modified only by the majority vote
of shareholders of that series or class.
    
 
                                      B-30
<PAGE>
   
    Shares of the Fund, when issued, are fully paid, nonassessable, fully
transferable and redeemable at the option of the holder. Shares are also
redeemable at the option of the Fund under certain circumstances. Each share of
each class is equal as to earnings, assets and voting privileges, except as
noted above, and each class of shares (with the exception of Class Z shares,
which are not subject to any distribution or service fees) bears the expenses
related to the distribution of its shares. Except for the conversion feature
applicable to the Class B shares, there are no conversion, preemptive or other
subscription rights. In the event of liquidation, each share of the Fund is
entitled to its portion of all of the Fund's assets after all debt and expenses
of the Fund have been paid. Since Class B and Class C shares generally bear
higher distribution expenses than Class A shares, the liquidation proceeds to
shareholders of those classes are likely to be lower than to Class A
shareholders and to Class Z shareholders, whose shares are not subject to any
distribution and/or service fees.
    
 
   
    The Fund does not intend to hold annual meetings of shareholders unless
otherwise required by law. The Fund will not be required to hold meetings of
shareholders unless, for example, the election of Directors is required to be
acted on by shareholders under the Investment Company Act. Shareholders have
certain rights, including the right to call a meeting upon the vote of 10% of
the Fund's outstanding shares for the purpose of voting on the removal of one or
more Directors or to transact any other business.
    
 
   
    Under the Articles of Incorporation, the Directors may authorize the
creation of additional series of shares (the proceeds of which would be invested
in separate, independently managed portfolios with distinct investment
objectives and policies and share purchase, redemption and net asset value
procedures) with such preferences, privileges, limitations and voting and
dividend rights as the Directors may determine. All consideration received by
the Fund for shares of any additional series, and all assets in which such
consideration is invested, would belong to that series (subject only to the
rights of creditors of that series) and would be subject to the liabilities
related thereto. Under the Investment Company Act, shareholders of any
additional series of shares would normally have to approve the adoption of any
advisory contract relating to such series and of any changes in the investment
policies related thereto. The Directors do not intend to authorize additional
series at the present time.
    
 
   
    The Directors have the power to alter the number and the terms of office of
the Directors and they may at any time lengthen their own terms or make their
terms of unlimited duration and appoint their own successors, provided that
always at least a majority of the Directors have been elected by the
shareholders of the Fund. The voting rights of shareholders are not cumulative,
so that holders of more than 50 percent of the shares voting can if they choose,
elect all Directors being selected, while the holders of the remaining shares
would be unable to elect any Director.
    
 
   
                PURCHASE, REDEMPTION AND PRICING OF FUND SHARES
    
 
   
    Shares of the Fund may be purchased at a price equal to the next determined
net asset value (NAV) per share plus a sales charge which, at the election of
the investor, may be imposed either (1) at the time of purchase (the Class A or
Class C shares) or (2) on a deferred basis (the Class B or Class C shares).
Class Z shares of the Fund are not subject to any sales or redemption charge and
are offered exclusively for sale to a limited group of investors at NAV.
    
 
   
    Each class of shares represents an interest in the same assets of the Fund
and is identical in all respects except that (1) each class is subject to
different sales charges and distribution and/or service fees (except for Class Z
shares, which are not subject to any sales charges and distribution and/or
service fees), which may affect performance, (2) each class has exclusive voting
rights with respect to any matter submitted to shareholders that relates solely
to its arrangement and has separate voting rights on any matter submitted to
shareholders in which the interests of one class differ from the interests of
any other class, (3) each class has a different exchange privilege, (4) only
Class B shares have a conversion feature and (5) Class Z shares are offered
exclusively for sale to a limited group of investors.

SELECTING A PURCHASE ALTERNATIVE
    
 
   
    The following is provided to assist you in determining which method of
purchase best suits your individual circumstances and is based on current fees
and expenses being charged to the Fund:
    
 
   
    If you intend to hold your investment in the Fund for less than 4 years and
do not qualify for a reduced sales charge on Class A shares, since Class A
shares are subject to an initial sales charge of 5% and Class B shares are
subject to a CDSC of 5% which declines to zero over a 6 year period, you should
consider purchasing Class C shares over either Class A or Class B shares.
    
 
   
    If you intend to hold your investment for longer than 4 years, but less than
5 years, and do not qualify for a reduced sales charge on Class A shares, you
should consider purchasing Class B or Class C shares over Class A shares. This
is because the initial sales charge plus the cumulative annual
distribution-related fee on Class A shares would exceed those of the Class B and
Class C shares if you redeem your investment during this time period. In
addition, more of your money would be invested initially in the case of Class C
shares, because of the relatively low initial sales charge, and all of your
money would be invested initially in the case of Class B shares, which are sold
at NAV.
    
 
                                      B-32
<PAGE>
   
    If you intend to hold your investment for longer than 5 years, you should
consider purchasing Class A shares over either Class B or Class C shares. This
is because the maximum sales charge plus the cumulative annual distribution-
related fee on Class A shares would be less than those of the Class B and Class
C shares.
    
 
   
    If you qualify for a reduced sales charge on Class A shares, it may be more
advantageous for you to purchase Class A shares over either Class B or Class C
shares regardless of how long you intend to hold your investment. However,
unlike Class B shares, you would not have all of your money invested initially
because the sales charge on Class A shares is deducted at the time of purchase.
    
 
   
    If you do not qualify for a reduced sales charge on Class A shares and you
purchase Class B or Class C shares, you would have to hold your investment for
more than 6 years in the case of Class B shares and 5 years in the case of Class
C shares for the higher cumulative annual distribution-related fee on those
shares plus, in the case of Class C shares, the 1% initial sales charge to
exceed the initial sales charge plus the cumulative annual distribution-related
fees on Class A shares. This does not take into account the time value of money,
which further reduces the impact of the higher Class B or Class C
distribution-related fee on the investment, fluctuations in NAV, the effect of
the return on the investment over this period of time or redemptions when the
CDSC is applicable.
    
 
   
REDUCTION AND WAIVER OF INITIAL SALES CHARGES--CLASS A SHARES
    
 
   
    BENEFIT PLANS. Class A shares may be purchased at NAV, without payment of an
initial sales charge, by pension, profit-sharing or other employee benefit plans
qualified under Section 401 of the Internal Revenue Code, deferred compensation
and annuity plans under Sections 403(b) and 457 of the Internal Revenue Code and
non-qualified deferred compensation plans that are sponsored by an employer that
has a tax-qualified benefit with Prudential, "rabbi" trusts and non-qualifed
deferred compensation plans that are sponsored by any employer that has a
tax-qualified plan with Prudential (collectively, Benefit Plans), provided that
the Benefit Plan has existing assets of at least $1 million invested in shares
of Prudential Mutual Funds (excluding money market funds other than those
acquired pursuant to the exchange privilege) or 250 eligible employees or
participants. In the case of Benefit Plans whose accounts are held directly with
the Transfer Agent or Prudential Securities and for which the Transfer Agent or
Prudential Securities does individual account recordkeeping (Direct Account
Benefit Plans) and Benefit Plans sponsored by Prudential, Prudential Securities
or its subsidiaries (Prudential Securities or Subsidiary Prototype Benefit
Plans), Class A shares may be purchased at NAV by participants who are repaying
loans made from such plans to the participant.
    
 
   
    PRUDENTIAL RETIREMENT PROGRAMS. Class A shares may be purchased at NAV by
certain savings, retirement and deferred compensation plans, qualified or
non-qualified under the Internal Revenue Code, for which Prudential provides
administrative or recordkeeping services, provided that (1) the plan has at
least $1 million in existing assets or 250 eligible employees and (2) the Fund
is an available investment option. These plans include pension, profit-sharing,
stock-bonus or other employee benefit plans under Section 401 of the Internal
Revenue Code, deferred compensation and annuity plans under Sections 457 and
403(b)(7) of the Internal Revenue Code and plans that participate in the
PruArray Program (benefit plan recordkeeping service) (hereafter referred to as
a PruArray Plan). All plans of a company (or affiliated companies under common
control) for which Prudential serves as plan administrator or recordkeeper are
aggregated in meeting the $1 million threshold, provided that Prudential has
been notified in advance of the establishment of the waiver of the sales charge
based on the aggregate assets. The term "existing assets" as used herein
includes stock issued by a plan sponsor, shares of Prudential Mutual Funds and
shares of certain unaffiliated mutual funds that participate in the PruArray
Plan (Participating Fund). "Existing assets" also include monies invested in The
Guaranteed Investment Account (GIA), a group annuity insurance product issued by
Prudential, the Guaranteed Insulated Separate Account, a separate account
offered by Prudential, and units of The Stable Value Fund (SVF), an unaffiliated
bank collective fund, Class A shares may also be purchased at NAV by plans that
have monies invested in GIA and SVF, provided (1) the purchase is made with the
proceeds of a redemption from either GIA or SVF and (2) Class A shares are an
investment option of the plan.
    
 
   
    PRUARRAY ASSOCIATION BENEFIT PLANS. Class A shares are also offered at NAV
to Benefit Plans or non-qualified plans sponsored by employers which are members
of a common trade, professional or membership association (Association) that
participate in the PruArray Plan provided that the Association enters into a
written agreement with Prudential. Such
    
 
                                      B-33
<PAGE>
   
Benefit Plans or non-qualified plans may purchase Class A shares at NAV without
regard to the assets or number of participants in the individual employer's
qualified Plan(s) or non-qualified plans so long as the employers in the
Association (1) have retirement plan assets in the aggregate of at least $1
million or 250 participants in the aggregate and (2) maintain their accounts
with the Transfer Agent.
    
 
   
    PRUARRAY SAVINGS PROGRAM. Class A shares are also offered at NAV to
employees of companies that enter into a written agreement with Prudential
Retirement Services to participate in the PruArray Savings Program. Under this
Program, a limited number of Prudential Mutual Funds are available for purchase
at NAV by Individual Retirement Accounts and Savings Accumulation Plans of the
company's employees. The Program is available only to (1) employees who open an
IRA or Savings Accumulation Plan account with the Transfer Agent and (2) spouses
of employees who open an IRA account with the Transfer Agent. The program is
offered to companies that have at least 250 eligible employees.
    
 
   
    SPECIAL RULES APPLICABLE TO RETIREMENT PLANS. After a Benefit Plan or
PruArray Plan qualifies to purchase Class A shares at NAV, all subsequent
purchases will be made at NAV.
    
 
   
    OTHER WAIVERS. In addition, Class A shares may be purchased at NAV, through
the Distributor or the Transfer Agent, by:
    
 
   
    - officers of the Prudential Mutual Funds (including the Fund),
    
 
   
    - employees of the Distributor, Prudential Securities, PIFM and their
      subsidiaries and members of the families of such persons who maintain an
      "employee related" account at Prudential Securities or the Transfer Agent,
    
 
   
    - employees of subadvisers of the Prudential Mutual Funds provided that
      purchases at NAV are permitted by such person's employer,
    
 
   
    - Prudential, employees and special agents of Prudential and its
      subsidiaries and all persons who have retired directly from active service
      with Prudential or one of its subsidiaries,
    
 
   
    - registered representatives and employees of brokers who have entered into
      a selected dealer agreement with the Distributor provided that purchases
      at NAV are permitted by such person's employer,
    
 
   
    - investors who have a business relationship with a financial adviser who
      joined Prudential Securities from another investment firm, provided that
      (1) the purchase is made within 180 days of the commencement of the
      financial adviser's employment at Prudential Securities, or within one
      year in the case of Benefit Plans, (2) the purchase is made with proceeds
      of a redemption of shares of any open-end non-money market fund sponsored
      by the financial adviser's previous employer (other than a fund which
      imposes a distribution or service fee of .25 of 1% or less) and (3) the
      financial adviser served as the client's broker on the previous purchase,
    
 
   
    - investors in Individual Retirement Accounts, provided the purchase is made
      with the proceeds of a tax-free rollover of assets from a Benefit Plan for
      which Prudential provides administrative or recordkeeping services and
      further provided that such purchase is made within 60 days of receipt of
      the Benefit Plan distribution,
    
 
   
    - orders placed by broker-dealers, investment advisers or financial planners
      who have entered into an agreement with the Distributor, who place trades
      for their own accounts or the accounts of their clients and who charge a
      management, consulting or other fee for their services (for example,
      mutual fund "wrap" or asset allocation programs), and
    
 
   
    - orders placed by clients of broker-dealers, investment advisers or
      financial planners who place trades for customer accounts if the accounts
      are linked to the master account of such broker-dealer, investment adviser
      or financial planner and the broker-dealer, investment adviser or
      financial planner charges its clients a separate fee for its services (for
      example, mutual fund "supermarket programs").
    
 
   
    For an investor to obtain any reduction or waiver of the initial sales
charges, at the time of the sale either the Transfer Agent must be notified
directly by the investor or the Distributor must be notified by the broker
facilitating the transaction that the sale qualifies for the reduced or waived
sales charge. The reduction or waiver will be granted subject to confirmation of
your entitlement. No initial sales charges are imposed upon Class A shares
acquired upon the reinvestment of dividends and distributions.

    COMBINED PURCHASE AND CUMULATIVE PURCHASE PRIVILEGE. If an investor or
eligible group of related investors purchases Class A shares of the Fund
concurrently with Class A shares of other Prudential Mutual Funds, the purchases
may be combined to take advantage of the reduced sales charges applicable to
larger purchases. See "How to Buy, Sell and Exchange Shares of the
Fund--Reducing or Waiving Class A's Initial Sales Charge" in the Prospectus.
    
 
    An eligible group of related Fund investors includes any combination of the
following:
 
   
    - an individual;
    
 
   
    - the individual's spouse, their children and their parents;
    
 
   
    - the individual's and spouse's Individual Retirement Account (IRA);
    
 
   
    - any company controlled by the individual (a person, entity or group that
      holds 25% or more of the outstanding voting securities of a company will
      be deemed to control the company, and a partnership will be deemed to be
      controlled by each of its general partners);
    
 
   
    - a trust created by the individual, the beneficiaries of which are the
      individual, his or her spouse, parents or children;
    
 
   
    - a Uniform Gifts to Minors Act/Uniform Transfers to Minors Act account
      created by the individual or the individual's spouse; and
    
 
   
    - one or more employee benefit plans of a company controlled by an
      individual.
    
 
    In addition, an eligible group of related Fund investors may include an
employer (or group of related employers) and one or more qualified retirement
plans of such employer or employers (an employer controlling, controlled by or
under common control with another employer is deemed related to that employer).
 
   
    The Transfer Agent, the Distributor or your broker must be notified at the
time of purchase that the investor is entitled to a reduced sales charge. The
reduced sales charges will be granted subject to confirmation of the investor's
holdings. The Combined Purchase and Cumulative Purchase Privilege does not apply
to individual participants in any retirement or group plans.
    
 
   
    RIGHTS OF ACCUMULATION. Reduced sales charges are also available through
Rights of Accumulation, under which an investor or an eligible group of related
investors, as described above under "Combined Purchase and Cumulative Purchase
Privilege," may aggregate the value of their existing holdings of shares of the
Fund and shares of other Prudential Mutual Funds (excluding money market funds
other than those acquired pursuant to the exchange privilege) to determine the
reduced sales charge. However, the value of shares held directly with the
Transfer Agent and through your broker will not be aggregated to determine the
reduced sales charge. The value of existing holdings for purposes of determining
the reduced sales charge is calculated using the maximum offering price (NAV
plus maximum sales charge) as of the previous business day. The Distributor or
the Transfer Agent must be notified at the time of purchase that the shareholder
is entitled to a reduced sales charge. The reduced sales charges will be granted
subject to confirmation of the investor's holdings. Rights of Accumulation are
not available to individual participants in any retirement or group plans.
    
 
    LETTERS OF INTENT. Reduced sales charges are available to investors (or an
eligible group of related investors), including retirement and group plans, who
enter into a written Letter of Intent providing for the purchase, within a
thirteen-month period, of shares of the Fund and shares of other Prudential
Mutual Funds (Investment Letter of Intent). Retirement and group plans may also
qualify to purchase Class A shares at NAV by entering into a Letter of Intent
whereby they agree to enroll, within a thirteen-month period, a specified number
of eligible employees or participants (Participant Letter of Intent).
 
   
    For purposes of the Investment Letter of Intent, all shares of the Fund and
shares of other Prudential Mutual Funds (excluding money market funds other than
those acquired pursuant to the exchange privilege) which were previously
purchased and are still owned are also included in determining the applicable
reduction. However, the value of shares held directly with the Transfer Agent,
Prudential or its affiliates, and through your broker will not be aggregated to
determine the reduced sales charge.
    
 
                                      B-35
<PAGE>
    A Letter of Intent permits a purchaser, in the case of an Investment Letter
of Intent, to establish a total investment goal to be achieved by any number of
investments over a thirteen-month period and, in the case of a Participant
Letter of Intent, to establish a minimum eligible employee or participant
enrollment goal over a thirteen-month period. Each investment made during the
period, in the case of an Investment Letter of Intent, will receive the reduced
sales charge applicable to the amount represented by the goal, as if it were a
single investment. In the case of a Participant Letter of Intent, each
investment made during the period will be made at net asset value. Escrowed
Class A shares totaling 5% of the dollar amount of the Letter of Intent will be
held by the Transfer Agent in the name of the purchaser, except in the case of
retirement and group plans where the employer or plan sponsor will be
responsible for paying any applicable sales charge. The effective date of an
Investment Letter of Intent (except in the case of retirement and group plans)
may be back-dated up to 90 days, in order that any investments made during this
90-day period, valued at the purchaser's cost, can be applied to the fulfillment
of the Letter of Intent goal, except in the case of retirement and group plans.
 
    The Investment Letter of Intent does not obligate the investor to purchase,
nor the Fund to sell, the indicated amount. Similarly, the Participant Letter of
Intent does not obligate the retirement or group plan to enroll the indicated
number of eligible employees or participants. In the event the Letter of Intent
goal is not achieved within the thirteen-month period, the purchaser (or the
employer or plan sponsor, in the case of any retirement or group plan) is
required to pay the difference between the sales charge otherwise applicable to
the purchases made during this period and sales charge actually paid. Such
payment may be made directly to the Distributor or, if not paid, the Distributor
will liquidate sufficient escrowed shares to obtain such difference. Investors
electing to purchase Class A shares of the Fund pursuant to a Letter of Intent
should carefully read such Letter of Intent.
 
    The Distributor must be notified at the time of purchase that the investor
is entitled to a reduced sales charge. The reduced sales charge will, in the
case of an Investment Letter of Intent, be granted subject to confirmation of
the investor's holdings or in the case of a Participant Letter of Intent,
subject to confirmation of the number of eligible employees or participants in
the retirement or group plan. Letters of Intent are not available to individual
participants in any retirement or group plans.
 
   
CLASS B SHARES
    
 
   
    The offering price of Class B shares for investors choosing one of the
deferred sales charge alternatives is the NAV next determined following receipt
of an order in proper form by the Transfer Agent, your broker or the
Distributor. Although there is no sales charge imposed at the time of purchase,
redemptions of Class B shares may be subject to a CDSC. See "Sale of
Shares--Contingent Deferred Sales Charges" below.
    
 
   
    The Distributor will pay, from its own resources, sales commissions of up to
4% of the purchase price of Class B shares to brokers, financial advisers and
other persons who sell Class B shares at the time of sale. This facilitates the
ability of the Fund to sell the Class B shares without an initial sales charge
being deducted at the time of purchase. The Distributor anticipates that it will
recoup its advancement of sales commissions from the combination of the CDSC and
the distribution fee.
    
 
   
CLASS C SHARES
    
 
   
    The offering price of Class C shares is the next determined NAV plus a 1%
sales charge. In connection with the sale of Class C shares, the Distributor
will pay, from its own resources, brokers, financial advisers and other persons
which distribute Class C shares a sale commission of up to 2% of the purchase
price at the time of the sale.
    
 
   
    BENEFIT PLANS. Class C shares may be purchased at NAV, without payment of an
initial sales charge, by Benefit Plans (as defined above). In the case of
Benefit Plans whose accounts are held directly with the Transfer Agent or
Prudential Securities and for which the Transfer Agent or Prudential Securities
does individual account recordkeeping (Direct Account Benefit Plans) and Benefit
Plans sponsored by Prudential, Prudential Securities or its subsidiaries
(Prudential Securities or Subsidiary Prototype Benefit Plans), Class C shares
may be purchased at NAV by participants who are repaying the loans made from
such plans to the participant.
    
 
                                      B-36
<PAGE>
   
    PRUDENTIAL RETIREMENT PLANS. The initial sales charge will be waived with
respect to purchases of Class C shares by qualified and non-qualified retirement
and deferred compensation plans participating in the PruArray Plan and other
plans for which Prudential provides administrative or recordkeeping services.
    
 
   
    INVESTMENT OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. Investors
may purchase Class C shares at NAV, without the initial sales charge, with the
proceeds from the redemption of shares of any unaffiliated registered investment
company which were not held through an account with any Prudential affiliate.
Such purchases must be made within 60 days of the redemption. Investors eligible
for this waiver include: (1) investors purchasing shares through an account at
Prudential Securities; (2) investors purchasing shares through an ADVANTAGE
Account or an Investor Account with Prusec; and (3) investors purchasing shares
through other brokers. This waiver is not available to investors who purchase
shares directly from the Transfer Agent. You must notify the Transfer Agent
directly or through your broker if you are entitled to this waiver and provide
the Transfer Agent with such supporting documents as it may deem appropriate.
    
 
   
CLASS Z SHARES
    
 
   
    Class Z shares of the Fund currently are available for purchase by the
following categories of investors:
    
 
   
    - pension, profit-sharing or other employee benefit plans qualified under
      Section 401 of the Internal Revenue Code, deferred compensation and
      annuity plans under Sections 457 and 403(b)(7) of the Internal Revenue
      Code and non-qualified plans for which the Fund is an available option
      (collectively, Benefit Plans), provided such Benefit Plans (in combination
      with other plans sponsored by the same employer or group of related
      employers) have at least $50 million in defined contribution assets,
    
 
   
    - participants in any fee-based program sponsored by an affiliate of the
      Distributor which includes mutual funds as investment options and for
      which the Fund is an available option,
    
 
   
    - certain participants in the MEDLEY Program (group variable annuity
      contracts) sponsored by Prudential for whom Class Z shares of the
      Prudential Mutual Funds are an available option,
    
 
   
    - Benefit Plans for which an affiliate of the Distributor provides
      administrative or recordkeeping services and as of September 20, 1996, (a)
      were Class Z shareholders of the Prudential Mutual Funds or (b) executed a
      letter of intent to purchase Class Z shares of the Prudential Mutual
      Funds,
    
 
   
    - current and former Directors/Trustees of the Prudential Mutual Funds
      (including the Fund),
    
 
   
    - employees of Prudential and/or Prudential Securities who participate in a
      Prudential-sponsored employee savings plan, and
    
 
   
    - Prudential with an investment of $10 million or more.
    
 
   
    After a Benefit Plan qualifies a purchase Class Z shares, all subsequent
purchases will be for Class Z shares.
    
 
   
    In connection with the sale of Class Z shares, the Manager, the Distributor
or one of their affiliates may pay brokers, financial advisers and other persons
which distribute shares a finder's fee, from its own resources, based on a
percentage of the net asset value of shares sold by such persons.
    
 
   
SALE OF SHARES
    
 
   
    You can redeem your shares at any time for cash at the NAV next determined
after the redemption request is received in proper form (in accordance with
procedures established by the Transfer Agent in connection with investors'
accounts) by the Transfer Agent, the Distributor or your broker. In certain
cases, however, redemption proceeds will be reduced by the amount of any
applicable CDSC, as described below. See "Contingent Deferred Sales Charges"
below. If you are redeeming your shares through a broker, your broker must
receive your sell order before the Fund computes its NAV for that day (that is
4:15 P.M., New York time) in order to receive that day's NAV. Your broker will
be responsible for furnishing all necessary documentation to the Distributor and
may charge you for its services in connection with redeeming shares of the Fund.
    
 
                                      B-37
<PAGE>
   
    If you hold shares of the Fund through Prudential Securities, you must
redeem your shares through Prudential Securities. Please contact your Prudential
Securities financial adviser.
    
 
   
    If you hold shares in non-certificate form, a written request for redemption
signed by you exactly as the account is registered is required. If you hold
certificates, the certificates, signed in the name(s) shown on the face of the
certificates, must be received by the Transfer Agent, the Distributor or your
broker in order for the redemption request to be processed. If redemption is
requested by a corporation, partnership, trust or fiduciary, written evidence of
authority acceptable to the Transfer Agent must be submitted before such request
will be accepted. All correspondence and documents concerning redemptions should
be sent to the Fund in care of its Transfer Agent, Prudential Mutual Fund
Services LLC, Attention: Redemption Services, P.O. Box 15010, New Brunswick, New
Jersey 08906-5010, the Distributor or to your broker.
    
 
   
    SIGNATURE GUARANTEE. If the proceeds of the redemption (1) exceed $50,000,
(2) are to be paid to a person other than the record owner, (3) are to be sent
to an address other than the address on the Transfer Agent's records, or (4) are
to be paid to a corporation, partnership, trust or fiduciary, the signature(s)
on the redemption request and on the certificates, if any, or stock power must
be guaranteed by an "eligible guarantor institution." An "eligible guarantor
institution" includes any bank, broker, dealer or credit union. The Transfer
Agent reserves the right to request additional information from, and make
reasonable inquiries of, any eligible guarantor institution. For clients of
Prusec, a signature guarantee may be obtained from the agency or office manager
of most Prudential Insurance and Financial Services or Preferred Services
offices. In the case of redemptions form a PruArray Plan, if the proceeds of the
redemption are invested in another investment option of the plan in the name of
the record holder and at the same address as reflected in the Transfer Agent's
records, a signature guarantee is not required.
    
 
   
    Payment for shares presented for redemption will be made by check within
seven days after receipt by the Transfer Agent, the Distributor or your broker
of the certificate and/or written request, except as indicated below. If you
hold shares through a broker, payment for shares presented for redemption will
be credited to your account at your broker, unless you indicate otherwise. Such
payment may be postponed or the right of redemption suspended at times (1) when
the New York Stock Exchange is closed for other than customary weekends and
holidays, (2) when trading on such Exchange is restricted, (3) when an emergency
exists as a result of which disposal by the Fund of securities owned by it is
not reasonably practicable or it is not reasonably practicable for the Fund
fairly to determine the value of its net assets, or (4) during any other period
when the Commission, by order, so permits; provided that applicable rules and
regulations of the Commission shall govern as to whether the conditions
prescribed in (2), (3) or (4) exist.
    
 
   
    REDEMPTION IN KIND. If the Directors determine that it would be detrimental
to the best interests of the remaining shareholders of the Fund to make payment
wholly or partly in cash, the Fund may pay the redemption price in whole or in
part by a distribution in kind of securities from the investment portfolio of
the Fund, in lieu of cash, in conformity with applicable rules of the
Commission. Securities will be readily marketable and will be valued in the same
manner as in a regular redemption. If your shares are redeemed in kind, you
would incur transaction costs in converting the assets into cash. The Fund,
however, has elected to be governed by Rule 18f-1 under the Investment Company
Act, under which the Fund is obligated to redeem shares solely in cash up to the
lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any
one shareholder.
    
 
   
    INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the
Directors may redeem all of the shares of any shareholder, other than a
shareholder which is an IRA or other tax-deferred retirement plan, whose account
has a net asset value of less than $500 due to a redemption. The Fund will give
such shareholders 60 days' prior written notice in which to purchase sufficient
additional shares to avoid such redemption. No CDSC will be imposed on any such
involuntary redemption.
    
 
   
    90-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not
previously exercised the repurchase privilege, you may reinvest any portion or
all of the proceeds of such redemption in shares of the Fund at the NAV next
determined after the order is received, which must be within 90 days after the
date of the redemption. Any CDSC paid in connection with such redemption will be
credited (in shares) to your account. (If less than a full repurchase is made,
the credit will be on a PRO RATA basis.) You must notify the Transfer Agent,
either directly or through the Distributor or your broker, at the time the
repurchase privilege is exercised to adjust your account for the CDSC you
previously paid. Thereafter, any redemptions will be subject to the CDSC
applicable at the time of the redemption. See "Contingent
    
 
                                      B-38
<PAGE>
   
Deferred Sales Charges" below. Exercise of the repurchase privilege will
generally not affect federal tax treatment of any gain realized upon redemption.
However, if the redemption was made within a 30 day period of the repurchase and
if the redemption resulted in a loss, some or all of the loss, depending on the
amount reinvested, may not be allowed for federal income tax purposes.
    
 
   
CONTINGENT DEFERRED SALES CHARGES
    
 
   
    Redemptions of Class B shares will be subject to a contingent deferred sales
charge or CDSC declining from 5% to zero over a six-year period. Class C shares
redeemed within 18 months of purchase (one year in the case of shares purchased
before November 2, 1998) will be subject to a 1% CDSC. The CDSC will be deducted
from the redemption proceeds and reduce the amount paid to you. The CDSC will be
imposed on any redemption by you which reduces the current value of your Class B
or Class C shares to an amount which is lower than the amount of all payments by
you for shares during the preceding six years, in the case of Class B shares,
and 18 months, in the case of Class C shares (one year for Class C shares
purchased before November 2, 1998). A CDSC will be applied on the lesser of the
original purchase price or the current value of the shares being redeemed.
Increases in the value of your shares or shares acquired through reinvestment of
dividends or distributions are not subject to a CDSC. The amount of any CDSC
will be paid to and retained by the Distributor.
    
 
   
    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of shares until the time of redemption
of such shares. Solely for purposes of determining the number of years from the
time of any payment for the purchase of shares, all payments during a month will
be aggregated and deemed to have been made on the last day of the month. The
CDSC will be calculated from the first day of the month after the initial
purchase, excluding the time shares were held in a money market fund. See
"Shareholder Investment Account-- Exchange Privilege."
    
 
   
    The following table sets forth the rates of the CDSC applicable to
redemptions of Class B shares:

    In determining whether a CDSC is applicable to a redemption, the calculation
will be made in a manner that results in the lowest possible rate. It will be
assumed that the redemption is made first of amounts representing shares
acquired pursuant to the reinvestment of dividends and distributions; then of
amounts representing the increase in NAV above the total amount of payments for
the purchase of Fund shares made during the preceding six years (five years for
Class B shares purchased prior to January 22, 1990); then of amounts
representing the cost of shares held beyond the applicable CDSC period; and
finally, of amounts representing the cost of shares held for the longest period
of time within the applicable CDSC period.
    
 
   
    For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided to
redeem $500 of your investment. Assuming at the time of the redemption the NAV
had appreciated to $12 per share, the value of your Class B shares would be
$1,260 (105 shares at $12 per share). The CDSC would not be applied to the value
of the reinvested dividend shares and the amount which represents appreciation
($260). Therefore, $240 of the $500 redemption proceeds ($500 minus $260) would
be charged at a rate of 4% (the applicable rate in the second year after
purchase) for a total CDSC of $9.60.
    
 
                                      B-39
<PAGE>
   
    For federal income tax purposes, the amount of the CDSC will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the
redemption of shares.
    
 
   
    WAIVER OF CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES. The CDSC will
be waived in the case of a redemption following the death or disability of a
shareholder or, in the case of a trust account, following the death or
disability of the grantor. The waiver is available for total or partial
redemptions of shares owned by a person, either individually or in joint tenancy
(with rights of survivorship), at the time of death or initial determination of
disability, provided that the shares were purchased prior to death or
disability.
    
 
   
    The CDSC will also be waived in the case of a total or partial redemption in
connection with certain distributions made without penalty under the Internal
Revenue Code from a tax-deferred retirement plan, an IRA or Section 403(b)
custodial account. These distributions are:
    
 
   
    (1)in the case of a tax-deferred retirement plan, a lump-sum or other
       distribution after retirement;
    
 
   
    (2)in the case of an IRA (including a Roth IRA), a lump-sum or other
       distribution after attaining age 59 1/2 or a periodic distribution based
on life expectancy;
    
 
   
    (3)in the case of a Section 403(b) custodial account, a lump sum or other
       distribution after attaining age 59 1/2; and
    
 
   
    (4)a tax-free return of an excess contribution or plan distributions
       following the death or disability of the shareholder, provided that the
shares were purchased prior to death or disability.
    
 
   
    The waiver does not apply in the case of a tax-free rollover or transfer of
assets, other than one following a separation from service (that is, following
voluntary or involuntary termination of employment or following retirement).
Under no circumstances will the CDSC be waived on redemptions resulting from the
termination of a tax-deferred retirement plan, unless such redemptions otherwise
qualify for a waiver as described above. In the case of Direct Account and
Prudential Securities or Subsidiary Prototype Benefit Plans, the CDSC will be
waived on redemptions which represent borrowings from such plans. Shares
purchased with amounts used to repay a loan from such plans on which a CDSC was
not previously deducted will thereafter be subject to a CDSC without regard to
the time such amounts were previously invested. In the case of a 401(k) plan,
the CDSC will also be waived upon the redemption of shares purchased with
amounts used to repay loans made from the account to the participant and from
which a CDSC was previously deducted.
    
 
   
    Finally, the CDSC will be waived to the extent that the proceeds from shares
redeemed are invested in Prudential Mutual Funds, The Guaranteed Investment
Account, the Guaranteed Insulated Separate Account or units of The Stable Value
Fund.
    
 
   
    SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on certain
redemptions from a Systematic Withdrawal Plan. On an annual basis, up to 12% of
the total dollar amount subject to the CDSC may be redeemed without charge. The
Transfer Agent will calculate the total amount available for this waiver
annually on the anniversary date of your purchase or, for shares purchased prior
to March 1, 1997, on March 1 of the current year. The CDSC will be waived (or
reduced) on redemptions until this threshold 12% is reached.
    
 
   
    In addition, the CDSC will be waived on redemptions of shares held by
Directors of the Fund.

QUANTITY DISCOUNT--CLASS B SHARES PURCHASED PRIOR TO AUGUST 1, 1994
 
    The CDSC is reduced on redemptions of Class B shares of the Fund purchased
prior to August 1, 1994 if immediately after a purchase of such shares, the
aggregate cost of all Class B shares of the Fund owned by you in a single
account exceeded $500,000. For example, if you purchase $100,000 of Class B
shares of the Fund and the following year purchase an additional $450,000 of
Class B shares with the result that the aggregate cost of your Class B shares of
the Fund following the second purchase was $550,000, the quantity discount would
be available for the second purchase of $450,000 but not for the first purchase
of $100,000. The quantity discount will be imposed at the following rates
depending on whether the aggregate value exceeded $500,000 or $1 million:

WAIVER OF CONTINGENT DEFERRED SALES CHARGES--CLASS C SHARES
    
 
   
    PRUDENTIAL RETIREMENT PLANS. The CDSC will be waived on redemptions from
qualified and non-qualified retirement and deferred compensation plans that
participate in the PruArray Program and other plans for which Prudential
provides administrative or recordkeeping services. The CDSC will also be waived
on redemptions from Benefit Plans sponsored by Prudential and its affiliates to
the extent that the redemption proceeds are invested in The Guaranteed
Investment Account, a group annuity insurance product issued by Prudential, the
Guaranteed Insulated Separate Account, a separate account offered by Prudential,
and units of The Stable Value Fund, an unaffiliated bank collective fund.
    
 
   
    OTHER BENEFIT PLANS. The CDSC will be waived on redemptions from Benefit
Plans holding shares through a broker not affiliated with Prudential and for
which the broker provides administrative or recordkeeping services.
    
 
   
CONVERSION FEATURE--CLASS B SHARE
    
 
   
    Class B shares will automatically convert to Class A shares on a quarterly
basis approximately seven years after purchase. Conversions will be effected at
relative net asset value without the imposition of any additional sales charge.
    
 
   
    Since the Fund tracks amounts paid rather than the number of shares bought
on each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will be
determined on each conversion date in accordance with the following formula: (i)
the ratio of (a) the amounts paid for Class B shares purchased at least seven
years prior to the conversion date to (b) the total amount paid for all Class B
shares purchased and then held in your account (ii) multiplied by the total
number of Class B shares purchased and then held in your account. Each time any
Eligible Shares in your account convert to Class A shares, all shares or amounts
representing Class B shares then in your account that were acquired through the
automatic reinvestment of dividends and other distributions will convert to
Class A shares.
    
 
   
    For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different net asset values per share, the number of Eligible Shares
calculated as described above will generally be either more or less than the
number of shares actually purchased approximately seven years before such
conversion date. For example, if 100 shares were initially purchased at $10 per
share (for a total of $1,000) and a second purchase of 100 shares was
subsequently made at $11 per share (for a total of $1,100), 95.24 shares would
convert approximately seven years from the initial purchase (I.E., $1,000
divided by $2,100 (47.62%), multiplied by 200 shares equals 95.24 shares). The
Manager reserves the right to modify the formula for determining the number of
Eligible Shares in the future as it deems appropriate on notice to shareholders.
    
 
   
    Since annual distribution-related fees are lower for Class A shares than
Class B shares, the per share NAV of the Class A shares may be higher than that
of the Class B shares at the time of conversion. Thus, although the aggregate
dollar value will be the same, you may receive fewer Class A shares than Class B
shares converted.
    
 
   
    For purposes of calculating the applicable holding period for conversions,
all payments for Class B shares during a month will be deemed to have been made
on the last day of the month, or for Class B shares acquired through exchange,
or a series of exchanges, on the last day of the month in which the original
payment for purchases of such Class B shares was made. For Class B shares
previously exchanged for shares of a money market fund, the time period during
which such shares were held in the money market fund will be excluded. For
example, Class B shares held in a money market fund for one year would not
convert to Class A shares until approximately eight years from purchase. For
purposes of measuring the time period during which shares are held in a money
market fund, exchanges will be deemed to have been made on the last day of the
month. Class B shares acquired through exchange will convert to Class A shares
after expiration of the conversion period applicable to the original purchase of
such shares.
    
 
   
    The conversion feature may be subject to the continuing availability of
opinions of counsel or rulings of the Internal Revenue Service (1) that the
dividends and other distributions paid on Class A, Class B, Class C and Class Z
shares will not constitute "preferential dividends" under the Internal Revenue
Code and (2) that the conversion of shares does not
    
 
                                      B-42
<PAGE>
   
constitute a taxable event. The conversion of Class B shares into Class A shares
may be suspended if such opinions or rulings are no longer available. If
conversions are suspended, Class B shares of the Fund will continue to be
subject, possibly indefinitely, to their higher annual distribution and service
fee.
    
 
                         SHAREHOLDER INVESTMENT ACCOUNT
 
    Upon the initial purchase of shares of the Fund, a Shareholder Investment
Account is established for each investor under which the shares are held for the
investor by the Transfer Agent. If a stock certificate is desired, it must be
requested in writing for each transaction. Certificates are issued only for full
shares and may be redeposited in the Account at any time. There is no charge to
the investor for issuance of a certificate. The Fund makes available to the
shareholder the following privileges and plans.
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS
 
   
    For the convenience of investors, all dividends and distributions are
automatically reinvested in full and fractional shares of the Fund. An investor
may direct the Transfer Agent in writing not less than 5 full business days
prior to the record date to have subsequent dividends and/or distributions sent
in cash rather than reinvested. In the case of recently purchased shares for
which registration instructions have not been received on the record date, cash
payment will be made directly to the broker. Any shareholder who receives a cash
payment representing a dividend or distribution may reinvest such dividend or
distribution at NAV by returning the check or the proceeds to the Transfer Agent
within 30 days after the payment date. Such investment will be made at the NAV
per share next determined after receipt of the check or proceeds by the Transfer
Agent. Such shareholder will receive credit for any CDSC paid in connection with
the amount of proceeds being reinvested.
    
 
EXCHANGE PRIVILEGE
 
    The Fund makes available to its shareholders the privilege of exchanging
their shares of the Fund for shares of certain other Prudential Mutual Funds,
including one or more specified money market funds, subject in each case to the
minimum investment requirements of such funds. Shares of such other Prudential
Mutual Funds may also be exchanged for shares of the Fund. All exchanges are
made on the basis of the relative NAV next determined after receipt of an order
in proper form. An exchange will be treated as a redemption and purchase for tax
purposes. For retirement and group plans having a limited menu of Prudential
Mutual Funds, the exchange privilege is available for those funds eligible for
investment in the particular program.
 
    It is contemplated that the exchange privilege may be applicable to new
mutual funds whose shares may be distributed by the Distributor.
 
   
    In order to exchange shares by telephone, you must authorize telephone
exchanges in your initial application form or by written notice to the Transfer
Agent and hold shares in non-certificate form. Thereafter, you may call the Fund
at (800) 225-1852 to execute a telephone exchange of shares, on weekdays, except
holidays, between the hours of 8:00 A.M. and 6:00 P.M., New York time. For your
protection and to prevent fraudulent exchanges, your telephone call will be
recorded and you will be asked to provide your personal identification number. A
written confirmation of the exchange transaction will be sent to you. Neither
the Fund nor its agents will be liable for any loss, liability or cost which
results from acting upon instructions reasonably believed to be genuine under
the foregoing procedures. All exchanges will be made on the basis of the
relative NAV of the two funds next determined after the request is received in
good order.
    
 
   
    If you hold shares through Prudential Securities, you must exchange your
shares by contacting your Prudential Securities financial adviser.
    
 
   
    If you hold certificates, the certificates, signed in the name(s) shown on
the face of the certificates, must be returned in order for the shares to be
exchanged.
    
 
   
    You may also exchange shares by mail by writing to Prudential Mutual Fund
Services LLC, Attention: Exchange Processing, P.O. Box 15010, New Brunswick, New
Jersey 08906-5010.
    
 
                                      B-43
<PAGE>
   
    In periods of severe market or economic conditions the telephone exchange of
shares may be difficult to implement and you should make exchanges by mail by
writing to Prudential Mutual Fund Services LLC, at the address noted above.
    
 
   
    CLASS A. Shareholders of the Fund may exchange their Class A shares for
Class A shares of certain other Prudential Mutual Funds, shares of Prudential
Government Securities Trust (Short-Intermediate Series) and shares of the money
market funds specified below. No fee or sales load will be imposed upon the
exchange. Shareholders of money market funds who acquired such shares upon
exchange of Class A shares may use the exchange privilege only to acquire Class
A shares of the Prudential Mutual Funds participating in the exchange privilege.
    
 
    The following money market funds participate in the Class A exchange
privilege:
 
       Prudential California Municipal Fund
         (California Money Market Series)
       Prudential Government Securities Trust
         (Money Market Series)
         (U.S. Treasury Money Market Series)
       Prudential Municipal Series Fund
         (Connecticut Money Market Series)
         (Massachusetts Money Market Series)
         (New Jersey Money Market Series)
         (New York Money Market Series)
       Prudential MoneyMart Assets, Inc. (Class A shares)
       Prudential Tax-Free Money Fund, Inc.
 
   
    CLASS B AND CLASS C. Shareholders of the Fund may exchange their Class B and
Class C shares for Class B and Class C shares, respectively, of certain other
Prudential Mutual Funds and shares of Prudential Special Money Market Fund,
Inc., a money market fund. No CDSC will be payable upon such exchange, but a
CDSC may be payable upon the redemption of the Class B and Class C shares
acquired as a result of an exchange. The applicable sales charge will be that
imposed by the fund in which shares were initially purchased and the purchase
date will be deemed to be the first day of the month after the initial purchase,
rather than the date of the exchange.
    
 
    Class B and Class C shares of the Fund may also be exchanged for shares of
Prudential Special Money Market Fund, Inc. without imposition of any CDSC at the
time of exchange. Upon subsequent redemption from such money market fund or
after re-exchange into the Fund, such shares will be subject to the CDSC
calculated by excluding the time such shares were held in the money market fund.
In order to minimize the period of time in which shares are subject to a CDSC,
shares exchanged out of the money market fund will be exchanged on the basis of
their remaining holding periods, with the longest remaining holding periods
being transferred first. In measuring the time period shares are held in a money
market fund and "tolled" for purposes of calculating the CDSC holding period,
exchanges are deemed to have been made on the last day of the month. Thus, if
shares are exchanged into the Fund from a money market fund during the month
(and are held in the Fund at the end of the month), the entire month will be
included in the CDSC holding period. Conversely, if shares are exchanged into a
money market fund prior to the last day of the month (and are held in the money
market fund on the last day of the month), the entire month will be excluded
from the CDSC holding period. For purposes of calculating the seven-year holding
period applicable to the Class B conversion feature, the time period during
which Class B shares were held in a money market fund will be excluded.
 
    At any time after acquiring shares of other funds participating in the Class
B or Class C exchange privilege, the shareholder may again exchange those shares
(and any reinvested dividends and distributions) for Class B or Class C shares
of the Fund, respectively, without subjecting such shares to any CDSC. Shares of
any fund participating in the Class B or Class C exchange privilege that were
acquired through reinvestment of dividends or distributions may be exchanged for
Class B or Class C shares of other funds, respectively, without being subject to
any CDSC.
 
    CLASS Z. Class Z shares may be exchanged for Class Z shares of other
Prudential Mutual Funds.
 
                                      B-44
<PAGE>
   
    SPECIAL EXCHANGE PRIVILEGES. A special exchange privilege is available for
shareholders who qualify to purchase Class A shares at NAV and for shareholders
who qualify to purchase Class Z shares. Under this exchange privilege, amounts
representing any Class B and Class C shares which are not subject to a CDSC held
in such a shareholder's account will be automatically exchanged for Class A
shares for shareholders who qualify to purchase Class A shares at NAV on a
quarterly basis, unless the shareholder elects otherwise. Similarly,
shareholders who qualify to purchase Class Z shares will have their Class B and
Class C shares which are not subject to a CDSC and their Class A shares
exchanged for Class Z shares on a quarterly basis. Eligibility for this exchange
privilege will be calculated on the business day prior to the date of the
exchange. Amounts representing Class B or Class C shares which are not subject
to a CDSC include the following: (1) amounts representing Class B or Class C
shares acquired pursuant to the automatic reinvestment of dividends and
distributions, (2) amounts representing the increase in the NAV above the total
amount of payments for the purchase of Class B or Class C shares and (3) amounts
representing Class B or Class C shares held beyond the applicable CDSC period.
Class B and Class C shareholders must notify the Transfer Agent either directly
or through Prudential Securities, Prusec or another broker that they are
eligible for this special exchange privilege.
    
 
   
    Participants in any fee-based program for which the Fund is an available
option will have their Class A shares, if any, exchanged for Class Z shares when
they elect to have those assets become a part of the fee-based program. Upon
leaving the program (whether voluntarily or not), such Class Z shares (and, to
the extent provided for in the program, Class Z shares acquired through
participation in the program) will be exchanged for Class A shares at NAV.
Similarly, participants in Prudential Securities' 401(k) Plan for which the
Fund's Class Z shares is an available option and who wish to transfer their
Class Z shares out of the Prudential Securities 401(k) Plan following separation
from service (that is, voluntary or involuntary termination of employment or
retirement) will have their Class Z shares exchanged for Class A shares at NAV.
    
 
   
    Additional details about the exchange privilege and prospectuses for each of
the Prudential Mutual Funds are available from the Fund's Transfer Agent, the
Distributor or your broker. The exchange privilege may be modified, terminated
or suspended on sixty days' notice, and any fund, including the Fund, or the
Distributor, has the right to reject any exchange application relating to such
fund's shares.
    
 
DOLLAR COST AVERAGING
 
    Dollar cost averaging is a method of accumulating shares by investing a
fixed amount of dollars in shares at set intervals. An investor buys more shares
when the price is low and fewer shares when the price is high. The average cost
per share is lower than it would be if a constant number of shares were bought
at set intervals.
 
    Dollar cost averaging may be used, for example, to plan for retirement, to
save for a major expenditure, such as the purchase of a home, or to finance a
college education. The cost of a year's education at a four-year college today
averages around $14,000 at a private college and around $6,000 at a public
university. Assuming these costs increase at a rate of 7% a year, as has been
projected, for the freshman class beginning in 2011, the cost of four years at a
private college could reach $210,000 and over $90,000 at a public university.(1)
 
- ------------
 
    (1)Source information concerning the costs of education at public and
private universities is available from The College Board Annual Survey of
Colleges, 1993. Average costs for private institutions include tuition, fees,
room and board for the 1993-1994 academic year.

    (2)The chart assumes an average rate of return of 8% (assuming monthly
compounding). This example is for illustrative purposes only and is not intended
to reflect the performance of an investment in shares of the Fund. The
investment return and principal value of an investment will fluctuate so that an
investor's shares when redeemed may be worth more or less than their original
cost.
 
   
AUTOMATIC INVESTMENT PLAN (AIP)
    
 
   
    Under AIP, an investor may arrange to have a fixed amount automatically
invested in shares of the Fund monthly by authorizing his or her bank account or
brokerage account (including a Prudential Securities Command Account) to be
debited to invest specified dollar amounts in shares of the Fund. The investor's
bank must be a member of the Automatic Clearing House System. Stock certificates
are not issued to AIP participants.
    
 
   
    Further information about this program and an application form can be
obtained from the Transfer Agent, the Distributor or your broker.
    
 
SYSTEMATIC WITHDRAWAL PLAN
 
   
    A systematic withdrawal plan is available to shareholders through the
Transfer Agent, the Distributor or your broker. Such withdrawal plan provides
for monthly or quarterly checks in any amount, except as provided below, up to
the value of the shares in the shareholder's account. Withdrawals of Class B or
Class C shares may be subject to a CDSC.
    
 
   
    In the case of shares held through the Transfer Agent (1) a $10,000 minimum
account value applies, (2) withdrawals may not be for less than $100 and (3) the
shareholder must elect to have all dividends and/or distributions automatically
reinvested in additional full and fractional shares at NAV on shares held under
this plan.
    
 
   
    The Transfer Agent, the Distributor or your broker act as agents for the
shareholder in redeeming sufficient full and fractional shares to provide the
amount of the periodic withdrawal payment. The systematic withdrawal plan may be
terminated at any time, and the Distributor reserves the right to initiate a fee
of up to $5 per withdrawal, upon 30 days' written notice to the shareholder.
    
 
    Withdrawal payments should not be considered as dividends, yield or income.
If periodic withdrawals continuously exceed reinvested dividends and
distributions, the shareholder's original investment will be correspondingly
reduced and ultimately exhausted.
 
   
    Furthermore, each withdrawal constitutes a redemption of shares, and any
gain or loss realized must generally be recognized for federal income tax
purposes. In addition, withdrawals made concurrently with the purchases of
additional shares are inadvisable because of the sales charge applicable to (1)
the purchase of Class A and Class C shares and (2) the redemption of Class B and
Class C shares. Each shareholder should consult his or her own tax adviser with
regard to the tax consequences of the systematic withdrawal plan, particularly
if used in connection with a retirement plan.
    
 
TAX-DEFERRED RETIREMENT PLANS
 
    Various tax-deferred retirement plans, including a 401(k) plan,
self-directed individual retirement accounts and "tax sheltered accounts" under
Section 403(b)(7) of the Internal Revenue Code are available through the
Distributor. These plans are for use by both self-employed individuals and
corporate employers. These plans permit either self-direction of accounts by
participants, or a pooled account arrangement. Information regarding the
establishment of these plans, the administration, custodial fees and other
details are available from Prudential Securities or the Transfer Agent.
 
                                      B-46

    Investors who are considering the adoption of such a plan should consult
with their own legal counsel or tax adviser with respect to the establishment
and maintenance of any such plan.
 
TAX-DEFERRED RETIREMENT ACCOUNTS
 
    INDIVIDUAL RETIREMENT ACCOUNTS. An individual retirement account (IRA)
permits the deferral of federal income tax on income earned in the account until
the earnings are withdrawn. The following chart represents a comparison of the
earnings in a personal savings account with those in an IRA, assuming a $2,000
annual contribution, an 8% rate of return and a 39.6% federal income tax bracket
and shows how much more retirement income can accumulate within an IRA as
opposed to a taxable individual savings account.

  (1) The chart is for illustrative purposes only and does not represent the
performance of the Fund or any specific investment. It shows taxable versus
tax-deferred compounding for the periods and on the terms indicated. Earnings in
a traditional IRA account will be subject to tax when withdrawn from the
account. Distributions from a Roth IRA which meet the conditions required under
the Internal Revenue Code will not be subject to tax upon withdrawal from the
account.
 
MUTUAL FUND PROGRAMS
 
    From time to time, the Fund may be included in a mutual fund program with
other Prudential Mutual Funds. Under such a program, a group of portfolios will
be selected and thereafter marketed collectively. Typically, these programs are
created with an investment theme, E.G., to seek greater diversification,
protection from interest rate movements or access to different management
styles. In the event such a program is instituted, there may be a minimum
investment requirement for the program as a whole. The Fund may waive or reduce
the minimum initial investment requirements in connection with such a program.
 
   
    The mutual funds in the program may be purchased individually or as part of
a program. Since the allocation of portfolios included in the program may not be
appropriate for all investors, individuals should consult their financial
adviser concerning the appropriate blend of portfolios for them. If investors
elect to purchase the individual mutual funds that constitute the program in an
investment ratio different from that offered by the program, the standard
minimum investment requirements for the individual mutual funds will apply.
    
 
                                NET ASSET VALUE
 
   
    The Fund's net asset value per share or NAV is determined by subtracting its
liabilities from the value of its assets and dividing the remainder by the
number of outstanding shares. NAV is calculated separately for each class.
    
 
   
    Under the Investment Company Act, the Board of Directors is responsible for
determining in good faith the fair value of securities of the Fund. In
accordance with procedures adopted by the Board of Directors, the value of
investments listed on a securities exchange and NASDAQ National Market System
securities (other than options on stock and stock indices) are valued at the
last sale price of such exchange system on the day of valuation or, if there was
no sale on such day, the mean between the last bid and asked prices on such day,
or at the bid price on such day in the absence of an asked price. Corporate
bonds (other than convertible debt securities) and U.S. Government securities
that are actively traded in the over-the-counter market, including listed
securities for which the primary market is believed by the Manager in
consultation with the Subadviser to be over-the-counter, are valued on the basis
of valuations provided by an independent pricing agent or principal market maker
which uses information with respect to transactions in bonds, quotations from
bond dealers, agency ratings, market transactions in comparable securities and
various relationships between securities in
    
 
                                      B-47
<PAGE>
   
determining value. Convertible debt securities that are actively traded in the
over-the-counter market, including listed securities for which the primary
market is believed by the Manager in consultation with the Subadviser to be
over-the-counter, are valued at the mean between the last reported bid and asked
prices provided by principal market makers. Options on stock and stock indices
traded on an exchange are valued at the mean between the most recently quoted
bid and asked prices on the respective exchange and futures contracts and
options thereon are valued at their last sale prices as of the close of trading
on the applicable commodities exchange or board of trade or, if there was no
sale on the applicable commodities exchange or board of trade on such day, at
the mean between the most recently quoted bid and asked prices on such exchange
or board of trade. Quotations of foreign securities in a foreign currency are
converted to U.S. dollar equivalents at the current rate obtained from a
recognized bank or dealer and foreign currency forward contracts are valued at
the current cost of covering or offsetting such contracts. Should an
extraordinary event, which is likely to affect the value of the security, occur
after the close of an exchange on which a portfolio security is traded, such
security will be valued at fair value considering factors determined in good
faith by the investment adviser under procedures established by and under the
general supervision of the Fund's Board of Directors.
    
 
   
    Securities or other assets for which reliable market quotations are not
readily available or for which the pricing agent or principal market maker does
not provide a valuation or methodology or provides a valuation or methodology
that, in the judgment of the Manager or Subadviser (or Valuation Committee or
Board of Directors) does not represent fair value, are valued by the Valuation
Committee or Board of Directors in consultation with the Manager or Subadviser,
including its portfolio manager, traders, and its research and credit analysts,
on the basis of the following factors: cost of the security, transactions in
comparable securities, relationships among various securities and such other
factors as may be determined by the Manager, Subadviser, Board of Directors or
Valuation Committee to materially affect the value of the security. Short-term
debt securities are valued at cost, with interest accrued or discount amortized
to the date of maturity, if their original maturity was 60 days or less, unless
this is determined by the Board of Directors not to represent fair value.
Short-term securities with remaining maturities of more than 60 days, for which
market quotations are readily available, are valued at their current market
quotations as supplied by an independent pricing agent or principal market
maker. The Fund will compute its NAV at 4:15 P.M., New York time, on each day
the New York Stock Exchange is open for trading except on days on which no
orders to purchase, sell or redeem Fund shares have been received or days on
which changes in the value of the Fund's portfolio securities do not affect NAV.
In the event the New York Stock Exchange closes early on any business day, the
NAV of the Fund's shares shall be determined at the time between such closing
and 4:15 P.M., New York time. The New York Stock Exchange is closed on the
following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
and Christmas Day.
    
 
   
    Although the legal rights of each class of shares are substantially
identical, the different expenses borne by each class will result in different
NAVs and dividends. NAV is calculated separately for each class. The NAV of
Class B and Class C shares will generally be lower than the NAV of Class A
shares as a result of the larger distribution-related fee to which Class B and
Class C shares are subject. The NAV of Class Z shares will generally be higher
than the NAV of Class A, Class B or Class C shares as a result of the fact that
the Class Z shares are not subject to any distribution or service fee. It is
expected, however, that the NAV of the four classes will tend to converge
immediately after the recording of dividends, if any, which will differ by
approximately the amount of the distribution and/or service fee expense accrual
differential among the classes.
    
 
                       TAXES, DIVIDENDS AND DISTRIBUTIONS
 
    The Fund is qualified and intends to remain qualified as a regulated
investment company under Subchapter M of the Internal Revenue Code. In order to
qualify as a regulated investment company, the Fund must, among other things,
(a) derive at least 90% of its annual gross income (without reduction for losses
from the sale or other disposition of securities) from dividends, interest,
payments with respect to securities loans and gains from the sale or other
disposition of securities or foreign currencies, or other income (including, but
not limited to, gains from options, futures or forward contracts) derived with
respect to its business of investing in such securities or currencies; (b)
diversify its holdings so that, at the end of each fiscal quarter, (i) at least
50% of the market value of the Fund's assets is represented by cash, U.S.
Government securities and other securities limited, in respect of any one
issuer, to an amount not greater than 5% of the market value of the Fund's
assets and 10% of the outstanding voting securities of such issuer, and (ii) not
more than 25%
 
                                      B-48
<PAGE>
   
of the value of its assets is invested in the securities of any one issuer
(other than U.S. Government securities); and (c) the Fund distribute to its
shareholders at least 90% of its net investment income and net short-term gains
(that is, the excess of net short-term capital gains over net long-term capital
losses) in each year.
    
 
    As a regulated investment company, the Fund will not be subject to federal
income tax on its net investment income and capital gains, if any, that it
distributes to its shareholders. The Fund intends to distribute to its
shareholders all such income and any gains. The Board of Directors of the Fund
will determine at least once a year whether to distribute any net long-term
capital gains in excess of any net short-term capital losses. In determining
amounts of capital gains to be distributed, any capital loss carryovers from
prior years will be offset against capital gains.
 
    In addition to the foregoing, a 4% nondeductible excise tax will be imposed
on the Fund to the extent the Fund does not meet certain minimum distribution
requirements by the end of each calendar year. For this purpose, any income or
gain retained by the Fund which is subject to income tax will be considered to
have been distributed by year-end. In addition, dividends declared in October,
November and December payable to shareholders of record on a specified date in
October, November and December and paid in the following January will be treated
as having been paid by the Fund and received by each shareholder on December 31
of the calendar year in which declared. Under this rule, therefore, a
shareholder may be taxed in one year on dividends or distributions actually
received in January of the following year.
 
   
    Gains or losses on sales of securities by the Fund will be long-term capital
gains or losses if the securities have been held by it for more than one year,
except in certain cases where the Fund acquires a put or writes a call thereon
or otherwise holds an offsetting position with respect to the securities. Other
gains or losses on the sale of securities will be short-term capital gains or
losses. Gains and losses on the sale, lapse or other termination of options on
stock will be treated as gains and losses from the sale of stock. For federal
income tax purposes, when call options which the Fund has written expire
unexercised, the premiums received by the Fund give rise to short-term capital
gains at the time of expiration. When a call written by the Fund is exercised,
the selling price of the stock is increased by the amount of the premium, and
the gain or loss on the sale of stock becomes long-term or short-term depending
on the stock's holding period. Certain futures contracts and options held by the
Fund will be required to be "marked-to-market" for federal income tax purposes,
that is, treated as having been sold at fair market value on the last day of the
Fund's fiscal year. Any gain or loss recognized on these deemed sales of these
futures contracts and options will be treated 60% as long-term capital gain or
loss, and the remainder will be treated as short-term capital gain or loss.
Certain of the Fund's transactions may be subject to wash sale, short sale,
constructive sale, anti-conversion and straddle provisions of the Internal
Revenue Code that may, among other things, require the Fund to defer recognition
of losses.
    
 
    The "straddle" provisions of the Internal Revenue Code may affect the
taxation of the Fund's transactions (including transactions in options on
securities, stock index futures and options on futures) and limit the
deductibility of any loss from the disposition of a position to the amount of
the unrealized gain on any offsetting position.
 
    Gains or losses attributable to fluctuations in exchange rates which occur
between the time the Fund accrues interest or other receivables or accrues
expenses or other liabilities denominated in a foreign currency and the time the
Fund actually collects such receivables or pays such liabilities are treated as
ordinary income or ordinary loss. Similarly, gains or losses on forward foreign
currency exchange contracts or dispositions of debt securities denominated in a
foreign currency attributable to fluctuations in the value of the foreign
currency between the date of acquisition of the security and the date of
disposition also are treated as ordinary gain or loss. These gains or losses,
referred to under the Internal Revenue Code as "Section 988" gains or losses,
increase or decrease the amount of the Fund's investment company taxable income
available to be distributed to its shareholders as ordinary income, rather than
increasing or decreasing the amount of the Fund's net capital gain. If Section
988 losses exceed other investment company taxable income during a taxable year,
the Fund would not be able to make any ordinary dividend distributions, or
distributions made before the losses were realized would be recharacterized as a
return of capital to shareholders, rather than as an ordinary dividend, reducing
each shareholder's basis in his or her Fund shares.
 
    Any loss realized on a sale, redemption or exchange of shares of the Fund by
a shareholder will be disallowed to the extent the shares are replaced within a
61-day period (beginning 30 days before the disposition of shares). Shares
purchased pursuant to the reinvestment of a dividend will constitute a
replacement of shares.
 
                                      B-49
<PAGE>
    If a shareholder acquires shares of the Fund and sells or otherwise disposes
of such shares within 90 days of acquisition, certain sales charges incurred in
acquiring such shares may not be included in the basis of such shares for
purposes of calculating gain or loss realized upon such sale or disposition.
 
    The per share dividends on Class B and Class C shares will be lower than the
per share dividends on Class A and Class Z shares as a result of the higher
distribution-related fee applicable to the Class B and Class C shares and lower
on Class A shares in relation to Class Z shares. The per share distributions of
net capital gains, if any, will be paid in the same amount for Class A, Class B,
Class C and Class Z shares. See "Net Asset Value."
 
    Shareholders electing to receive dividends and distributions in the form of
additional shares will have a cost basis for federal income tax purposes in each
share so received equal to the net asset value of a share of the Fund on the
reinvestment date.
 
    Any dividends or distributions paid shortly after a purchase by an investor
may have the effect of reducing the per share net asset value of the investor's
shares by the per share amount of the dividends or distributions. Furthermore,
such dividends or distributions, although in effect a return of capital, are
subject to federal income taxes. Prior to purchasing shares of the Fund,
therefore, the investor should carefully consider the impact of dividends or
capital gains distributions which are expected to be or have been announced.
 
    Dividends and distributions may also be subject to state and local taxes.

    AVERAGE ANNUAL TOTAL RETURN. The Fund may from time to time advertise its
average annual total return. Average annual total return is determined
separately for Class A, Class B, Class C and Class Z shares.
    
 
    Average annual total return is computed according to the following formula:
 
                         P(1+T) to the power of n = ERV
 
Where: P = a hypothetical initial payment of $1000.
 
       T = average annual total return.
 
       n = number of years.
 
   
       ERV = Ending Redeemable Value of a hypothetical $1000 investment made at
             the beginning of the 1, 5 or 10 year periods at the end of the 1, 5
             or 10 year periods (or fractional portion thereof).
    
 
   
    Average annual total return takes into account any applicable initial or
contingent deferred sales charges but does not take into account any federal or
state income taxes that may be payable upon redemption.

           ERV = Ending Redeemable Value of a hypothetical $1000 investment made
                 at the beginning of the 1, 5 or 10 year periods at the end of
                 the 1, 5, or 10 year periods (or fractional portion thereof).

    YIELD. The Fund may from time to time advertise its yield as calculated over
a 30-day period. Yield is calculated separately for Class A, Class B, Class C
and Class Z shares. This yield will be computed by dividing the Fund's net
investment income per share earned during this 30-day period by the maximum
offering price per share on the last day of this period. Yield is calculated
according to the following formula:
 
                            a - b
               YIELD = 2[( -------   +1)to the power of 6 - 1]
                             cd
 
Where: a=dividends and interest earned during the period.
     b=expenses accrued for the period (net of reimbursements).
     c=the average daily number of shares outstanding during the
       period that were entitled to receive dividends.
     d=the maximum offering price per share on the last day of the period.
 
    Yield fluctuates and an annualized yield quotation is not a representation
by the Fund as to what an investment in the Fund will actually yield for any
given period.
 
   
    The Fund's 30-day yields for the period ended December 31, 1998 were   %,

Notes to Financial Statements                      PRUDENTIAL UTILITY FUND, INC.
- --------------------------------------------------------------------------------
Prudential Utility Fund, Inc. (the 'Fund') is registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
Its investment objective is to seek total return, through a combination of
income and capital appreciation. The Fund seeks to achieve this objective by
investing primarily in equity and debt securities of utility companies. Utility
companies include electric, gas, gas pipeline, telephone, telecommunications,
water, cable, airport, seaport and toll road companies. The ability of issuers
of certain debt securities held by the Fund to meet their obligations may be
affected by economic developments in a specific industry or region.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

Securities Valuation: Investments traded on a national securities exchange are
valued at the last reported sales price on the primary exchange on which they
are traded. Securities traded in the over-the-counter market (including
securities listed on exchanges whose primary market is believed to be
over-the-counter) and listed securities for which no sale was reported on that
date are valued at the mean between the last reported bid and asked prices.
Short-term securities which mature in more than 60 days are valued based on
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost.

In connection with repurchase agreements with U.S. financial institutions, it is
the Fund's policy that its custodian or designated subcustodians, as the case
may be under triparty repurchase agreements, takes possession of the underlying
collateral securities, the value of which exceeds the principal amount of the
repurchase transaction, including accrued interest. If the seller defaults and
the value of the collateral declines or if bankruptcy proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Fund may be delayed or limited.

All securities are valued as of 4:15 P.M., New York time.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
closing daily rate of exchange;

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the year, the Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the year. Similarly, the Fund does not
isolate the effect of changes in foreign exchange rates from the fluctuations
arising from changes in the market prices of portfolio securities sold during
the year.

Net realized gains or losses on foreign currency transactions represent net
foreign exchange gains or losses from sales and maturities of short-term
securities, disposition of foreign currency, gains or losses realized between
the trade and settlement dates of security transactions, and the difference
between amounts of dividends, interest and foreign withholding taxes recorded on
the Fund's books and the US dollar equivalent amounts actually received or paid.
Net currency gains and losses from valuing foreign currency denominated assets,
except portfolio securities, and liabilities (other than investments) at year
end exchange rates are reflected as a component of unrealized appreciation or
depreciation on investments and foreign currencies.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of investments
and foreign currencies are calculated on the identified cost basis. Dividend
income is recorded on the ex-dividend date and interest income is recorded on
the accrual basis. The Fund amortizes discounts on purchases of debt securities
as adjustments to interest income. Expenses are recorded on the accrual basis
which may require the use of certain estimates by management.

Net investment income (other than distribution fees) and unrealized and realized
gains or losses are allocated daily to each class of shares based upon the
relative proportion of net assets of each class at the beginning of the day.

Dividends and Distributions: Dividends from net investment income are declared
and paid quarterly. The Fund will distribute at least annually any net capital
gains in excess of capital loss carryforwards. Dividends and distributions are
recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: It is the Fund's policy to continue to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable net income to its shareholders. Therefore, no
federal income tax provision is required.

Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.

Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to decrease undistributed net investment income by $738,273
and increase accumulated net realized gain on investments by $738,273 for
realized foreign currency losses during the year ended December 31, 1997. Net
investment income, net realized gains and net assets were not affected by this
change.
- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. Pursuant to a subadvisory agreement between PIFM and The Prudential
Investment Corporation ('PIC'), PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the cost of the
subadviser's services, the cost of compensation of officers of the Fund,
occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears
all other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .60% of the Fund's average daily net assets up to $250 million, .50% of
the next $500 million, .45% of the next $750 million, .40% of the next $500
million, .35% of the next $2 billion, .325% of the next $2 billion and .30% of
the average daily net assets of the Fund in excess of $6 billion.

The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund. The Fund compensates PSI for distributing and
servicing the Fund's Class A, Class B and Class C shares, pursuant to plans of
distribution, (the 'Class A, B and C Plans'), regardless of expenses actually
incurred by PSI. The distribution fees for Class A, B and C shares are accrued
daily and payable monthly. PSI also incurs the expenses of distributing the
Fund's Class Z shares under the distribution agreement, none of which is
reimbursed or paid by the Fund.

Pursuant to the Class A, B and C Plans, the Fund compensates PSI for
distribution-related activities at an annual rate of up to .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C shares, respectively.
Such expenses under the Plans were .25 of 1%, 1% and 1% of the average daily net
assets of the Class A, B and C shares, respectively, for the year ended December
31, 1997.

PSI has advised the Fund that it has received approximately $745,100 in
front-end sales charges resulting from sales of Class A shares during the year
ended December 31, 1997. From these fees, PSI paid such sales charges to Pruco
Securities Corporation, an affiliated broker-dealer, which in turn paid
commissions to salespersons and incurred other distribution costs.

PSI advised the Fund that for the year ended December 31, 1997, it received
approximately $2,226,900 and $2,800 in contingent deferred sales charges imposed
upon redemptions by certain Class B and Class C shareholders, respectively.

PSI, PIFM and PIC are indirect, wholly owned subsidiaries of The Prudential
Insurance Company of America.

The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the year ended
December 31, 1997. The Funds pay a commitment fee at an annual rate of .055 of
1% on the unused portion of the credit facility. The commitment fee is accrued
and paid quarterly on a pro-rata basis by the Funds. The Agreement expired on
December 30, 1997 and has been extended through December 29, 1998 under the same
terms.

Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,

brokerage commissions from portfolio transactions executed on behalf of the
Fund.

for the year ended December 31, 1997, were $638,350,290 and $1,119,864,954,
respectively.

The federal income tax basis of the Fund's investments at December 31, 1997 was

Notes to Financial Statements (Unaudited)          PRUDENTIAL UTILITY FUND, INC.
- --------------------------------------------------------------------------------
Prudential Utility Fund, Inc. (the 'Fund') is registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
Its investment objective is to seek total return, through a combination of
income and capital appreciation. The Fund seeks to achieve this objective by
investing primarily in equity-related and debt securities of utility companies.
Utility companies include electric, gas, gas pipeline, telephone,
telecommunications, water, cable, airport, seaport and toll road companies. The
ability of issuers of certain debt securities held by the Fund to meet their
obligations may be affected by economic developments in a specific industry or
region.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

Securities Valuation: Investments traded on a national securities exchange are
valued at the last reported sales price on the primary exchange on which they
are traded. Securities traded in the over-the-counter market (including
securities listed on exchanges whose primary market is believed to be
over-the-counter) and listed securities for which no sale was reported on that
date are valued at the mean between the last reported bid and asked prices, or
at the bid price in the absence of an asked price. Short-term securities which
mature in more than 60 days are valued based on current market quotations.
Short-term securities which mature in 60 days or less are valued at amortized
cost.

In connection with repurchase agreements with U.S. financial institutions, it is
the Fund's policy that its custodian or designated subcustodians, as the case
may be under triparty repurchase agreements, takes possession of the underlying
collateral securities, the value of which exceeds the principal amount of the
repurchase transaction, including accrued interest. If the seller defaults and
the value of the collateral declines or if bankruptcy proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Fund may be delayed or limited.

All securities are valued as of 4:15 p.m., New York time.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
closing daily rate of exchange;

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the period, the Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of securities held at the end of the period. Similarly, the Fund does not
isolate the effect of changes in foreign exchange rates from the fluctuations
arising from changes in the market prices of portfolio securities sold during
the period.

Net realized gains or losses on foreign currency transactions represent net
foreign exchange gains or losses from sales and maturities of short-term
securities, disposition of foreign currency, gains or losses realized between
the trade and settlement dates of security transactions, and the difference
between amounts of dividends, interest and foreign withholding taxes recorded on
the Fund's books and the U.S. dollar equivalent amounts actually received or
paid. Net currency gains and losses from valuing foreign currency denominated
assets, except portfolio securities, and liabilities (other than investments) at
period end exchange rates are reflected as a component of unrealized
appreciation or depreciation on investments and foreign currencies.
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of investments
and foreign currencies are calculated on the identified cost basis. Dividend
income is recorded on the ex-dividend date and interest income is recorded on
the accrual basis. The Fund amortizes discounts on purchases of debt securities
as adjustments to interest income. Expenses are recorded on the accrual basis
which may require the use of certain estimates by management.

Net investment income (other than distribution fees) and unrealized and realized
gains or losses are allocated daily to each class of shares based upon the
relative proportion of net assets of each class at the beginning of the day.

Dividends and Distributions: Dividends from net investment income are declared
and paid quarterly. The Fund will distribute at least annually any

<PAGE>

Notes to Financial Statements (Unaudited)          PRUDENTIAL UTILITY FUND, INC.
- --------------------------------------------------------------------------------
net capital gains in excess of capital loss carryforwards. Dividends and
distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Taxes: It is the Fund's policy to continue to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable net income to its shareholders. Therefore, no
federal income tax provision is required.

Withholding taxes on foreign dividends have been provided for in accordance with
the Fund's understanding of the applicable country's tax rules and rates.

Reclassification of Capital Accounts: The Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to decrease undistributed net investment income by $676,243
and increase accumulated net realized gain on investments by $676,243 for
realized foreign currency losses during the six months ended June 30, 1998. Net
investment income, net realized gains and net assets were not affected by this
change.

- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. Pursuant to a subadvisory agreement between PIFM and The Prudential
Investment Corporation ('PIC'), PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the cost of the
subadviser's services, the cost of compensation of officers of the Fund,
occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears
all other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .60% of the Fund's average daily net assets up to $250 million, .50% of
the next $500 million, .45% of the next $750 million, .40% of the next $500
million, .35% of the next $2 billion, .325% of the next $2 billion and .30% of
the average daily net assets of the Fund in excess of $6 billion.
The Fund had a distribution agreement with Prudential Securities Incorporated
('PSI'), which acted as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund. The Fund compensated PSI for distributing and
servicing the Fund's Class A, Class B and Class C shares, pursuant to plans of
distribution, (the 'Class A, B and C Plans'), regardless of expenses actually
incurred by PSI. The distribution fees for Class A, B and C shares were accrued
daily and payable monthly. PSI also incurred the expenses of distributing the
Fund's Class Z shares under the distribution agreement, none of which was
reimbursed or paid by the Fund. Effective July 1, 1998, Prudential Investment
Management Services LLC ('PIMS') became the distributor of the Fund and is
serving the Fund under the same terms and conditions as under the arrangement
with PSI.

Pursuant to the Class A, B and C Plans, the Fund compensated PSI for
distribution-related activities at an annual rate of up to .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C shares, respectively.
Such expenses under the Plans were .25 of 1%, 1% and 1% of the average daily net
assets of the Class A, B and C shares, respectively, for the six months ended
June 30, 1998.

PSI has advised the Fund that it has received approximately $717,000 in
front-end sales charges resulting from sales of Class A shares during the six
months ended June 30, 1998. From these fees, PSI paid such sales charges to
Pruco Securities Corporation, an affiliated broker-dealer, which in turn paid
commissions to salespersons and incurred other distribution costs.

PSI advised the Fund that for the six months ended June 30, 1998, it received
approximately $820,000 and $3,500 in contingent deferred sales charges imposed
upon redemptions by certain Class B and Class C shareholders, respectively.

PSI, PIFM, PIC and PIMS are indirect, wholly owned subsidiaries of The
Prudential Insurance Company of America.

The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the six months
ended June 30, 1998. The Funds pay a commitment fee at an annual rate of .055 of
1% on the unused portion of the credit facility. The commitment fee is accrued
and paid quarterly on a pro rata basis by the Funds. The Agreement expires on
December 29, 1998.

Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended June 30, 1998,
the Fund incurred fees of approximately $2,215,000 for the services of PMFS. As
of June 30, 1998, approximately $372,000 of such fees were due to PMFS. Transfer
agent fees and expenses in the Statement of Operations also include certain
out-of-pocket expenses paid to nonaffiliates.

- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the six months ended June 30, 1998, were $286,729,850 and $226,116,951,
respectively.

The federal income tax basis of the Fund's investments at June 30, 1998 was
$3,064,546,349 and, accordingly, net unrealized appreciation for federal income
tax purposes was $1,954,303,854 (gross unrealized appreciation--$2,000,162,090;
gross unrealized depreciation--$45,858,236).

The Fund elected to treat approximately $302,200 of net currency losses incurred
during the two month period ended December 31, 1997 as having incurred in the
current fiscal year.

- ------------------------------------------------------------
Note 5. Joint Repurchase Agreement Account

The Fund, along with other affiliated registered investment companies, transfers
uninvested cash balances into a single joint account, the daily aggregate
balance of which is invested in one or more repurchase agreements collateralized
by U.S. Treasury or federal agency obligations. As of June 30, 1998, the Fund
had a 6.59% undivided interest in the joint account. The undivided interest for
the Fund represents $81,860,000 in the principal amount. As of such date, each
repurchase agreement in the joint account and the collateral therefor were as
follows:

Bear Stearns & Co., Inc., 5.85%, in the principal amount of $345,000,000,
repurchase price $345,056,063, due 7/1/98. The value of the collateral including
accrued interest was $353,215,323.

Goldman Sachs & Co. Inc., 5.20%, in the principal amount of $206,264,000,
repurchase price $206,293,794, due 7/1/98. The value of the collateral including
accrued interest was $210,389,609.

Warburg Dillon Read LLC, 5.93%, in the principal amount of $345,000,000,
repurchase price $345,056,829, due 7/1/98. The value of the collateral including
accrued interest was $352,174,874.

Salomon Smith Barney Inc., 5.70%, in the principal amount of $345,000,000,
repurchase price $345,054,625, due 7/1/98. The value of the collateral including
accrued interest was $352,383,850.

- ------------------------------------------------------------
Note 6. Capital

The Fund offers Class A, Class B, Class C and Class Z shares. Class A shares are
sold with a front-end sales charge of up to 5%. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a contingent
deferred sales charge of 1% during the first year. Class B shares automatically
convert to Class A shares on a quarterly basis approximately seven years after
purchase. A special exchange privilege is also available for shareholders who

                   APPENDIX I--GENERAL INVESTMENT INFORMATION
 
    The following terms are used in mutual fund investing.
 
ASSET ALLOCATION
 
    Asset allocation is a technique for reducing risk and providing balance.
Asset allocation among different types of securities within an overall
investment portfolio helps to reduce risk and to potentially provide stable
returns, while enabling investors to work toward their financial goal(s). Asset
allocation is also a strategy to gain exposure to better performing asset
classes while maintaining investment in other asset classes.
 
DIVERSIFICATION
 
    Diversification is a time-honored technique for reducing risk, providing
"balance" to an overall portfolio and potentially achieving more stable returns.
Owning a portfolio of securities mitigates the individual risks (and returns) of
any one security. Additionally, diversification among types of securities
reduces the risks (and general returns) of any one type of security.
 
DURATION
 
    Debt securities have varying levels of sensitivity to interest rates. As
interest rates fluctuate, the value of a bond (or a bond portfolio) will
increase or decrease. Longer term bonds are generally more sensitive to changes
in interest rates. When interest rates fall, bond prices generally rise.
Conversely, when interest rates rise, bond prices generally fall.
 
    Duration is an approximation of the price sensitivity of a bond (or a bond
portfolio) to interest rate changes. It measures the weighted average maturity
of a bond's (or a bond portfolio's) cash flows, I.E., principal and interest
rate payments. Duration is expressed as a measure of time in years--the longer
the duration of a bond (or a bond portfolio), the greater the impact of interest
rate changes on the bond's (or the bond portfolio's) price. Duration differs
from effective maturity in that duration takes into account call provisions,
coupon rates and other factors. Duration measures interest rate risk only and
not other risks, such as credit risk and, in the case of non-U.S. dollar
denominated securities, currency risk. Effective maturity measures the final
maturity dates of a bond (or a bond portfolio).
 
MARKET TIMING
 
    Market timing--buying securities when prices are low and selling them when
prices are relatively higher--may not work for many investors because it is
impossible to predict with certainty how the price of a security will fluctuate.
However, owning a security for a long period of time may help investors off-set
short-term price volatility and realize positive returns.
 
POWER OF COMPOUNDING
 
    Over time, the compounding of returns can significantly impact investment
returns. Compounding is the effect of continuous investment on long-term
investment results, by which the proceeds of capital appreciation (and income
distributions, if elected) are reinvested to contribute to the overall growth of
assets. The long-term investment results of compounding may be greater than that
of an equivalent initial investment in which the proceeds of capital
appreciation and income distributions are taken in cash.
 
STANDARD DEVIATION
 
    Standard deviation is an absolute (non-relative) measure of volatility
which, for a mutual fund, depicts how widely the returns varied over a certain
period of time. When a fund has a high standard deviation, its range of
performance has been very wide, implying greater volatility potential. Standard
deviation is only one of several measures of a fund's volatility.

Generally, stock returns are due to capital appreciation and the reinvestment of
gains. Bond returns are due mainly to reinvesting interest. Also, stock prices
usually are more volatile than bond prices over the long-term. Small stock
returns for 1926-1980 are those of stocks comprising the 5th quintile of the New
York Stock Exchange. Thereafter, returns are those of the Dimensional Fund
Advisors (DFA) Small Company Fund. Common stock returns are based on the S&P
Composite Index, a market-weighted, unmanaged index of 500 stocks (currently) in
a variety of industries. It is often used as a broad measure of stock market
performance.
 
Long-term government bond returns are measured using a constant one-bond
portfolio with a maturity of roughly 20 years. Treasury bill returns are for a
one-month bill. Treasuries are guaranteed by the government as to the timely
payment of principal and interest; equities are not. Inflation is measured by
the consumer price index (CPI).

    Set forth below is historical performance data relating to various sectors
of the fixed-income securities markets. The chart shows the historical total
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds,
U.S. high yield bonds and world government bonds on an annual basis from 1987
through 1997. The total returns of the indices include accrued interest, plus
the price changes (gains or losses) of the underlying securities during the
period mentioned. The data is provided to illustrate the varying historical
total returns and investors should not consider this performance data as an
indication of the future performance of the Fund or of any sector in which the
Fund invests.
 
   
    All information relies on data obtained from statistical services, reports
and other services believed by the Manager to be reliable. Such information has
not been verified. The figures do not reflect the operating expenses and fees of
a mutual fund. See "Risk/Return Summary--Fees and Expenses" in the prospectus.
The net effect of the deduction of the operating expenses of a mutual fund on
the historical total returns, including the compounded effect over time, could
be substantial.

$36 billion of individual retirement plan assets, such as 401(k) plans. As of
December 31, 1997, Prudential had more than $370 billion in assets under
management. Prudential Investments, a business group of Prudential (of which
Prudential Mutual Funds is a key part), manages over $211 billion in assets of

    (1)PIC serves as the Subadviser to substantially all of the Prudential
Mutual Funds. Wellington Management Company serves as the subadviser to Global
Utility Fund, Inc., Nicholas-Applegate Capital Management as the subadviser to
Nicholas-Applegate Fund, Inc., Jennison Associates LLC as one of the subadvisers
to The Prudential Investment Portfolios, Inc. and Mercator Asset Management LP
as the Subadviser to International Stock Series, a portfolio of Prudential World
Fund, Inc. There are multiple subadvisers for The Target Portfolio Trust.

    The Prudential Mutual Funds have over 30 portfolio managers who manage over
$55 billion in mutual fund and variable annuity assets. Some of Prudential's
portfolio managers have over 20 years of experience managing investment
portfolios.
 
    From time to time, there may be media coverage of portfolio managers and
other investment professionals associated with the Manager and the Subadviser in
national and regional publications, on television and in other media.
Additionally, individual mutual fund portfolios are frequently cited in surveys
conducted by national and regional publications and media organizations such as
THE WALL STREET JOURNAL, THE NEW YORK TIMES, BARRON'S and USA TODAY.
 
    EQUITY FUNDS. Forbes magazine listed Prudential Equity Fund among twenty
mutual funds on its Honor Roll in its mutual fund issue of August 28, 1995.
Honorees are chosen annually among mutual funds (excluding sector funds) which
are open to new investors and have had the same management for at least five
years. Forbes considers, among other criteria, the total return of a mutual fund
in both bull and bear markets as well as a fund's risk profile. Prudential
Equity Fund is managed with a "value" investment style by PIC. In 1995,
Prudential Securities introduced Prudential Jennison Fund, a growth-style equity
fund managed by Jennison Associates LLC, a premier institutional equity manager
and a subsidiary of Prudential.
 
    HIGH YIELD FUNDS. Investing in high yield bonds is a complex and research
intensive pursuit. A separate team of high yield bond analysts monitor
approximately 200 issues held in the Prudential High Yield Fund (currently the
largest fund of its kind in the country) along with 100 or so other high yield
bonds, which may be considered for purchase.(3) Non-investment grade bonds, also
known as junk bonds or high yield bonds, are subject to a greater risk of loss
of principal and interest including default risk than higher-rated bonds.
Prudential high yield portfolio managers and analysts meet face-to-face with
almost every bond issuer in the High Yield Fund's portfolio annually, and have
additional telephone contact throughout the year.
 
    Prudential's portfolio managers are supported by a large and sophisticated
research organization. Fourteen investment grade bond analysts monitor the
financial viability of approximately 1,750 different bond issuers in the
investment grade corporate and municipal bond markets--from IBM to small
municipalities, such as Rockaway Township, New Jersey. These analysts consider
among other things sinking fund provisions and interest coverage ratios.
 
    Prudential's portfolio managers and analysts receive research services from
almost 200 brokers and market service vendors. They also receive nearly 100
trade publications and newspapers--from PULP AND PAPER FORECASTER to WOMEN'S
WEAR DAILY--to keep them informed of the industries they follow.
 
    Prudential Mutual Funds' traders scan over 100 computer monitors to collect
detailed information on which to trade. From natural gas prices in the Rocky
Mountains to the results of local municipal elections, a Prudential portfolio
manager or trader is able to monitor it if it's important to a Prudential Mutual
Fund.
 
    Prudential Mutual Funds trade approximately $31 billion in U.S. and foreign
government securities a year. PIC seeks information from government policy
makers. In 1995, Prudential's portfolio managers met with several senior U.S.
and foreign government officials, on issues ranging from economic conditions in
foreign countries to the viability of index-linked securities in the United
States.
 
    Prudential Mutual Funds' portfolio managers and analysts met with over 1,200
companies in 1995, often with the Chief Executive Officer (CEO) or Chief
Financial Officer (CFO). They also attended over 250 industry conferences.
 
    Prudential Mutual Fund global equity managers conducted many of their visits
overseas, often holding private meetings with a company in a foreign language
(our global equity managers speak 7 different languages, including Mandarin
Chinese).
 
    TRADING DATA.(4) On an average day, Prudential Mutual Funds' U.S. and
foreign equity trading desks traded $77 million in securities representing over
3.8 million shares with nearly 200 different firms. Prudential Mutual Funds'

bond trading desks traded $157 million in government and corporate bonds on an
average day. That represents more in daily trading than most bond funds tracked
by Lipper even have in assets.(5) Prudential Mutual Funds' money market desk
traded $3.2 billion in money market securities on an average day, or over $800
billion a year. They made a trade every 3 minutes of every trading day. In 1994,
the Prudential Mutual Funds effected more than 40,000 trades in money market
securities and held on average $20 billion of money market securities.(6)
 
    Based on complex-wide data, on an average day, over 7,250 shareholders
telephoned Prudential Mutual Fund Services LLC, the Transfer Agent of the
Prudential Mutual Funds, on the Prudential Mutual Funds' toll-free number. On an
annual basis, that represents approximately 1.8 million telephone calls
answered.

ITEM 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT.
    
 
    None.
 
   
ITEM 25.  INDEMNIFICATION.
    
 
   
    As permitted by Sections 17(h) and (i) of the Investment Company Act of 1940
(the 1940 Act) and pursuant to Article VI of the Fund's By-Laws (Exhibit b to
the Registration Statement), officers, directors, employees and agents of the
Registrant will not be liable to the Registrant, any stockholder, officer,
director, employee, agent or other person for any action or failure to act,
except for bad faith, willful misfeasance, gross negligence or reckless
disregard of duties, and those individuals may be indemnified against
liabilities in connection with the Registrant, subject to the same exceptions.
Section 2-418 of Maryland General Corporation Law permits indemnification of
directors who acted in good faith and reasonably believed that the conduct was
in the best interests of the Registrant. As permitted by Section 17(i) of the
1940 Act, pursuant to Section 10 of the Distribution Agreement (Exhibit e(2) to
the Registration Statement), the Distributor of the Registrant may be
indemnified against liabilities which it may incur, except liabilities arising
from bad faith, gross negligence, willful misfeasance or reckless disregard of
duties.
    
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (Securities Act) may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the 1940 Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in connection with the successful defense
of any action, suit or proceeding) is asserted against the Registrant by such
director, officer or controlling person in connection with the shares being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1940 Act and will be governed by the final
adjudication of such issue.
 
    The Registrant has purchased an insurance policy insuring its officers and
directors against liabilities, and certain costs of defending claims against
such officers and directors, to the extent such officers and directors are not
found to have committed conduct constituting willful misfeasance, bad faith,
gross negligence or reckless disregard in the performance of their duties. The
insurance policy also insures the Registrant against the cost of indemnification
payments to officers and directors under certain circumstances.
 
   
    Section 9 of the amended Management Agreement (Exhibit d (2) to the
Registration Statement) and Section 4 of the Subadvisory Agreement (Exhibit d
(1) to the Registration Statement) limit the liability of Prudential Investments
Fund Management LLC (PIFM) and The Prudential Investment Corporation (PIC),
respectively, to liabilities arising from willful misfeasance, bad faith or
gross negligence in the performance of their respective duties or from reckless
disregard by them of their respective obligations and duties under the
agreements.
    
 
    The Registrant hereby undertakes that it will apply the indemnification
provisions of its By-Laws and each Distribution Agreement in a manner consistent
with Release No. 11330 of the Securities and Exchange Commission under the 1940
Act so long as the interpretation of Sections 17(h) and 17(i) of such Act remain
in effect and are consistently applied.

                                  DEALER AGREEMENT

                   PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC


     Prudential Investment Management Services LLC ("Distributor") and
_________________ ("Dealer") have agreed that Dealer will participate in the
distribution of shares ("Shares") of all the funds and series thereof (as they
may exist from time to time) comprising the Prudential Mutual Fund Family (each
a "Fund" and collectively the "Funds") and any classes thereof for which
Distributor now or in the future serves as principal underwriter and
distributor, subject to the terms of this Dealer Agreement ("Agreement").  Any
such additional Funds will be included in this Agreement upon Distributor's
written notification to Dealer.

     1.   LICENSING

          a.   Dealer represents and warrants that it is: (i) a broker-dealer
registered with the Securities and Exchange Commission ("SEC"); (ii) a member in
good standing of the National Association of Securities Dealers, Inc. ("NASD");
and (iii) licensed by the appropriate regulatory agency of each state or other
jurisdiction in which Dealer will offer and sell Shares of the Funds, to the
extent necessary to perform the duties and activities contemplated by this
Agreement.

          b.   Dealer represents and warrants that each of its partners,
directors, officers, employees, and agents who will be utilized by Dealer with
respect to its duties and activities under this Agreement is either
appropriately licensed or exempt from such licensing requirements by the
appropriate regulatory agency of each state or other jurisdiction in which
Dealer will offer and sell Shares of the Funds.

          c.   Dealer agrees that:  (i) termination or suspension of its
registration with the SEC; (ii) termination or suspension of its membership with
the NASD; or (iii) termination or suspension of its license to do business by
any state or other jurisdiction or federal regulatory agency shall immediately
cause the termination of this Agreement.  Dealer further agrees to immediately
notify Distributor in writing of any such action or event.

          d.   Dealer agrees that this Agreement is in all respects subject to
the Conduct Rules of the NASD and such Conduct Rules shall control any provision
to the contrary in this Agreement.

          e.   Dealer agrees to be bound by and to comply with all applicable
state and federal laws and all rules and regulations promulgated thereunder
generally affecting the sale or distribution of mutual fund shares.

     2.   ORDERS

          a.   Dealer agrees to offer and sell Shares of the Funds (including
those of each of its classes) only at the regular public offering price
applicable to such Shares and in effect at the time of each transaction.  The
procedures relating to all orders and the handling of each order (including the
manner of computing the net asset value of Shares and the effective time of
orders received from Dealer) are subject to:  (i) the terms of the then current
prospectus and statement of


                                         A-1
<PAGE>

additional information (including any supplements, stickers or amendments
thereto) relating to each Fund, as filed with the SEC ("Prospectus"); (ii) the
new account application for each Fund, as supplemented or amended from time to
time; and  (iii) Distributor's written instructions and multiple class pricing
procedures and guidelines, as provided to Dealer from time to time.  To the
extent that the Prospectus contains provisions that are inconsistent with this
Agreement or any other document, the terms of the Prospectus shall be
controlling.

          b.   Distributor reserves the right at any time, and without notice to
Dealer, to suspend the sale of Shares or to withdraw or limit the offering of
Shares.  Distributor reserves the unqualified right not to accept any specific
order for the purchase or sale of Shares.

          c.   In all offers and sales of the Shares to the public, Dealer is
not authorized to act as broker or agent for, or employee of, Distributor, any
Fund or any other dealer, and Dealer shall not in any manner represent to any
third party that Dealer has such authority or is acting in such capacity.
Rather, Dealer agrees that it is acting as principal for Dealer's own account or
as agent on behalf of Dealer's customers in all transactions in Shares, except
as provided in Section 3.i. hereof.  Dealer acknowledges that it is solely
responsible for all suitability determinations with respect to sales of Shares
of the Funds to Dealer's customers and that Distributor has no responsibility
for the manner of Dealer's performance of, or for Dealer's acts or omissions in
connection with, the duties and activities Dealer provides under this Agreement.

          d.   All orders are subject to acceptance by Distributor in its sole
discretion and become effective only upon confirmation by Distributor.

          e.   Distributor agrees that it will accept from Dealer orders placed
through a remote terminal or otherwise electronically transmitted via the
National Securities Clearing Corporation ("NSCC") Fund/Serv Networking program,
provided, however, that appropriate documentation thereof and agreements
relating thereto are executed by both parties to this Agreement, including in
particular the standard NSCC Networking Agreement and any other related
agreements between Distributor and Dealer deemed appropriate by Distributor, and
that all accounts opened or maintained pursuant to that program will be governed
by applicable NSCC rules and procedures.  Both parties further agree that, if
the NSCC Fund/Serv Networking program is used to place orders, the standard NSCC
Networking Agreement will control insofar as there is any conflict between any
provision of the Dealer Agreement and the standard NSCC Networking Agreement.


     3.   DUTIES OF DEALER

          a.   Dealer agrees to purchase Shares only from Distributor or from
Dealer's customers.

          b.   Dealer agrees to enter orders for the purchase of Shares only
from Distributor and only for the purpose of covering purchase orders Dealer has
already received from its customers or for Dealer's own bona fide investment.

          c.   Dealer agrees to date and time stamp all orders received by
Dealer and promptly, upon receipt of any and all orders, to transmit to
Distributor all orders received prior to


                                         A-2
<PAGE>

the time described in the Prospectus for the calculation of each Fund's net
asset value so as to permit Distributor to process all orders at the price next
determined after receipt by Dealer, in accordance with the Prospectus. Dealer
agrees not to withhold placing orders for Shares with Distributor so as to
profit itself as a result of such inaction.

          d.   Dealer agrees to maintain records of all purchases and sales of
Shares made through Dealer and to furnish Distributor or regulatory authorities
with copies of such records upon request.  In that regard, Dealer agrees that,
unless Dealer holds Shares as nominee for its customers or participates in the
NSCC Fund/Serv Networking program, at certain matrix levels, it will provide
Distributor with all necessary information to comply properly with all federal,
state and local reporting requirements and backup and nonresident alien
withholding requirements for its customer accounts including, without
limitation, those requirements that apply by treating Shares issued by the Funds
as readily tradable instruments.  Dealer represents and agrees that all Taxpayer
Identification Numbers ("TINs") provided are certified, and that no account that
requires a certified TIN will be established without such certified TIN.  With
respect to all other accounts, including Shares held by Dealer in omnibus
accounts and Shares purchased or sold through the NSCC Fund/Serv Networking
program, at certain matrix levels, Dealer agrees to perform all federal, state
and local tax reporting with respect to such accounts, including without
limitation redemptions and exchanges.

          e.   Dealer agrees to distribute or cause to be delivered to its
customers Prospectuses, proxy solicitation materials and related information and
proxy cards, semi-annual and annual shareholder reports and any other materials
in compliance with applicable legal requirements, except to the extent that
Distributor expressly undertakes to do so in writing.

          f.   Dealer agrees that if any Share is repurchased by any Fund or is
tendered for redemption within seven (7) business days after confirmation by
Distributor of the original purchase order from Dealer, Dealer shall forfeit its
right to any concession or commission received by Dealer with respect to such
Share and shall forthwith refund to Distributor the full concession allowed to
Dealer or commission paid to Dealer on the original sale.  Distributor agrees to
notify Dealer of such repurchase or redemption within a reasonable time after
settlement.  Termination or cancellation of this Agreement shall not relieve
Dealer from its obligation under this provision.

          g.   Dealer agrees that payment for Shares ordered from Distributor
shall be in Fed Funds, New York clearinghouse or other immediately available
funds and that such funds shall be received by Distributor by the earlier of:
(i) the end of the third (3rd) business day following Dealer's receipt of the
customer's order to purchase such Shares; or (ii) the settlement date
established in accordance with Rule 15c6-1 under the Securities Exchange Act of
1934, as amended.  If such payment is not received by Distributor by such date,
Dealer shall forfeit its right to any concession or commission with respect to
such order, and Distributor reserves the right, without notice, forthwith to
cancel the sale, or, at its option, to sell the Shares ordered back to the Fund,
in which case Distributor may hold Dealer responsible for any loss, including
loss of profit, suffered by Distributor resulting from Dealer's failure to make
payment as aforesaid.  If a purchase is made by check, the purchase is deemed
made upon conversion of the purchase instrument into Fed Funds, New York
clearinghouse or other immediately available funds.


                                         A-3
<PAGE>

          h.   Dealer agrees that it: (i) shall assume responsibility for any
loss to the Fund caused by a correction to any order placed by Dealer that is
made subsequent to the trade date for the order, provided such order correction
was not based on any negligence on Distributor's part; and (ii) will immediately
pay such loss to the Fund upon notification.

          i.   Dealer agrees that in connection with orders for the purchase of
Shares on behalf of any IRAs, 401(k) plans or other retirement plan accounts, by
mail, telephone, or wire, Dealer shall act as agent for the custodian or trustee
of such plans (solely with respect to the time of receipt of the application and
payments), and Dealer shall not place such an order with Distributor until it
has received from its customer payment for such purchase and, if such purchase
represents the first contribution to such a retirement plan account, the
completed documents necessary to establish the retirement plan.  Dealer agrees
to indemnify Distributor and its affiliates for any claim, loss, or liability
resulting from incorrect investment instructions received by Distributor from
Dealer.

          j.   Dealer agrees that it will not make any conditional orders for
the purchase or redemption of Shares and acknowledges that Distributor will not
accept conditional orders for Shares.

          k.   Dealer agrees that all out-of-pocket expenses incurred by it in
connection with its activities under this Agreement will be borne by Dealer.

          l.   Dealer agrees that it will keep in force appropriate broker's
blanket bond insurance policies covering any and all acts of Dealer's partners,
directors, officers, employees, and agents adequate to reasonably protect and
indemnify the Distributor and the Funds against any loss which any party may
suffer or incur, directly or indirectly, as a result of any action by Dealer or
Dealer's partners, directors, officers, employees, and agents.

          m.   Dealer agrees that it will maintain the required net capital as
specified by the rules and regulations of the SEC, NASD and other regulatory
authorities.

     4.   DEALER COMPENSATION

          a.   On each purchase of Shares by Dealer from Distributor, the total
sales charges and dealer concessions or commissions, if any, payable to Dealer
shall be as stated on Schedule A to this Agreement, which may be amended by
Distributor from time to time.  Distributor reserves the right, without prior
notice, to suspend or eliminate such dealer concession or commissions by
amendment, sticker or supplement to the then current Prospectus for each Fund.
Such sales charges and dealer concessions or commissions, are subject to
reduction under a variety of circumstances as described in each Fund's then
current Prospectus.  For an investor to obtain any reduction, Distributor must
be notified at the time of the sale that the sale qualifies for the reduced
sales charge.  If Dealer fails to notify Distributor of the applicability of a
reduction in the sales charge at the time the trade is placed, neither
Distributor nor any Fund will be liable for amounts necessary to reimburse any
investor for the reduction that should have been effected.  Dealer acknowledges
that no sales charge or concession or commission will be paid to Dealer on the
reinvestment of dividends or capital gains reinvestment or on Shares acquired in
exchange for Shares of another Fund, or class thereof, having the same sales
charge structure as the Fund, or class thereof, from which the exchange was
made, in accordance with the Prospectus.


                                         A-4
<PAGE>

          b.   In accordance with the Funds' Prospectuses, Distributor or any
affiliate may, but is not obligated to, make payments to dealers from
Distributor's own resources as compensation for certain sales that are made at
net asset value ("Qualifying Sales").  If Dealer notifies Distributor of a
Qualifying Sale, Distributor may make a contingent advance payment up to the
maximum amount available for payment on the sale.  If any of the Shares
purchased in a Qualifying Sale are redeemed within twelve (12) months of the end
of the month of purchase, Distributor shall be entitled to recover any advance
payment attributable to the redeemed Shares by reducing any account payable or
other monetary obligation Distributor may owe to Dealer or by making demand upon
Dealer for repayment in cash.  Distributor reserves the right to withhold
advances to Dealer, if for any reason Distributor believes that it may not be
able to recover unearned advances from Dealer.

          c.   With respect to any Fund that offers Shares for which
distribution plans have been adopted under Rule 12b-1 under the Investment
Company Act of 1940, as amended ("Rule 12b-1 Plans"), Distributor also is
authorized to pay the Dealer continuing distribution and/or service fees, as
specified in Schedule A and the relevant Fund Prospectus, with respect to Shares
of any such Fund, to the extent that Dealer provides distribution, marketing,
administrative and other services and activities regarding the promotion of such
Shares and the maintenance of related shareholder accounts.

          d.   In connection with the receipt of distribution fees and/or
service fees under Rule 12b-1 Plans applicable to Shares purchased by Dealer's
customers, Distributor directs Dealer to provide enhanced shareholder services
such as: processing purchase and redemption transactions; establishing
shareholder accounts; and providing certain information and assistance with
respect to the Funds.  (Redemption levels of shareholder accounts assigned to
Dealer will be considered in evaluating Dealer's continued ability to receive
payments of distribution and/or service fees.)  In addition, Dealer agrees to
support Distributor's marketing efforts by, among other things, granting
reasonable requests for visits to Dealer's office by Distributor's wholesalers
and marketing representatives, including all Funds covered by a Rule 12b-1 Plan
on Dealer's "approved," "preferred" or other similar product lists, if
applicable, and otherwise providing satisfactory product, marketing and sales
support.  Further, Dealer agrees to provide Distributor with supporting
documentation concerning the shareholder services provided, as Distributor may
reasonably request from time to time.

          e.   All Rule 12b-1 Plan distribution and/or servicing fees shall be
based on the value of Shares attributable to Dealer's customers and eligible for
such payment, and shall be calculated on the basis of and at the rates set forth
in the compensation schedule then in effect.  Without prior approval by a
majority of the outstanding shares of a Fund, the aggregate annual fees paid to
Dealer pursuant to any Rule 12b-1 Plan shall not exceed the amounts stated as
the "annual maximums" in each Fund's Prospectus, which amount shall be a
specified percent of the value of the Fund's net assets held in Dealer's
customers' accounts that are eligible for payment pursuant to the Rule 12b-1
Plans (determined in the same manner as each Fund uses to compute its net assets
as set forth in its then current Prospectus).

          f.   The provisions of any Rule 12b-1 Plan between the Funds and the
Distributor shall control over this Agreement in the event of any inconsistency.
Each Rule 12b-1 Plan in effect on the date of this Agreement is described in the
relevant Fund's Prospectus.  Dealer


                                         A-5
<PAGE>

hereby acknowledges that all payments under Rule 12b-1 Plans are subject to
limitations contained in such Rule 12b-1 Plans and may be varied or discontinued
at any time.

     5.   REDEMPTIONS, REPURCHASES AND EXCHANGES

          a.   The Prospectus for each Fund describes the provisions whereby the
Fund, under all ordinary circumstances, will redeem Shares held by shareholders
on demand.  Dealer agrees that it will not make any representations to
shareholders relating to the redemption of their Shares other than the
statements contained in the Prospectus and the underlying organizational
documents of the Fund, to which it refers, and that Dealer will pay as
redemption proceeds to shareholders the net asset value, minus any applicable
deferred sales charge or redemption fee, determined after receipt of the order
as discussed in the Prospectus.

          b.   Dealer agrees not to repurchase any Shares from its customers at
a price below that next quoted by the Fund for redemption or repurchase, I.E.,
at the net asset value of such Shares, less any applicable deferred sales
charge, or redemption fee, in accordance with the Fund's Prospectus.  Dealer
shall, however, be permitted to sell Shares for the account of the customer or
record owner to the Funds at the repurchase price then currently in effect for
such Shares and may charge the customer or record owner a fair service fee or
commission for handling the transaction, provided Dealer discloses the fee or
commission to the customer or record owner.  Nevertheless, Dealer agrees that it
shall not under any circumstances maintain a secondary market in such
repurchased Shares.

          c.   Dealer agrees that, with respect to a redemption order it has
made, if instructions in proper form, including any outstanding certificates,
are not received by Distributor within the time customary or the time required
by law, the redemption may be canceled forthwith without any responsibility or
liability on Distributor's part or on the part of any Fund, or Distributor, at
its option, may buy the shares redeemed on behalf of the Fund, in which latter
case Distributor may hold Dealer responsible for any loss, including loss of
profit, suffered by Distributor resulting from Distributor's failure to settle
the redemption.

          d.   Dealer agrees that it will comply with any restrictions and
limitations on exchanges described in each Fund's Prospectus, including any
restrictions or prohibitions relating to frequent purchases and redemptions
(i.e., market timing).

     6.   MULTIPLE CLASSES OF SHARES

          Distributor may, from time to time, provide Dealer with written
guidelines or standards relating to the sale or distribution of Funds offering
multiple classes of Shares with different sales charges and distribution-related
operating expenses.

     7.   FUND INFORMATION

          a.   Dealer agrees that neither it nor any of its partners, directors,
officers, employees, and agents is authorized to give any information or make
any representations concerning Shares of any Fund except those contained in the
Fund's then current Prospectus or in materials provided by Distributor.


                                         A-6
<PAGE>

          b.   Distributor will supply to Dealer Prospectuses, reasonable
quantities of sales literature, sales bulletins, and additional sales
information as provided by Distributor.  Dealer agrees to use only advertising
or sales material relating to the Funds that: (i) is supplied by Distributor, or
(ii) conforms to the requirements of all applicable laws or regulations of any
government or authorized agency having jurisdiction over the offering or sale of
Shares of the Funds and is approved in writing by Distributor in advance of its
use.  Such approval may be withdrawn by Distributor in whole or in part upon
written notice to Dealer, and Dealer shall, upon receipt of such notice,
immediately discontinue the use of such sales literature, sales bulletins and
advertising.  Dealer is not authorized to modify or translate any such materials
without Distributor's prior written consent.

     8.   SHARES

          a.   Distributor acts solely as agent for the Fund and Distributor
shall have no obligation or responsibility with respect to Dealer's right to
purchase or sell Shares in any state or jurisdiction.

          b.   Distributor shall periodically furnish Dealer with information
identifying the states or jurisdictions in which it is believed that all
necessary notice, registration or exemptive filings for Shares have been made
under applicable securities laws such that offers and sales of Shares may be
made in such states or jurisdictions.  Distributor shall have no obligation to
make such notice, registration or exemptive filings with respect to Shares in
any state or jurisdiction.

          c.   Dealer agrees not to transact orders for Shares in states or
jurisdictions in which it has been informed that Shares may not be sold or in
which it and its personnel are not authorized to sell Shares.

          d.   Distributor shall have no responsibility, under the laws
regulating the sale of securities in the United States or any foreign
jurisdiction, with respect to the qualification or status of Dealer or Dealer's
personnel selling Fund Shares.  Distributor shall not, in any event, be liable
or responsible for the issue, form, validity, enforceability and value of such
Shares or for any matter in connection therewith.

          e.   Dealer agrees that it will make no offers or sales of Shares in
any foreign jurisdiction, except with the express written consent of
Distributor.

     9.   INDEMNIFICATION

          a.   Dealer agrees to indemnify, defend and hold harmless Distributor
and the Funds and their predecessors, successors, and affiliates, each current
or former partner, officer, director, employee, shareholder or agent and each
person who controls or is controlled by Distributor from any and all losses,
claims, liabilities, costs, and expenses, including attorney fees, that may be
assessed against or suffered or incurred by any of them howsoever they arise,
and as they are incurred, which relate in any way to:  (i) any alleged violation
of any statute or regulation (including without limitation the securities laws
and regulations of the United States or any state or foreign country) or any
alleged tort or breach of contract, related to the offer or sale by Dealer of
Shares of the Funds pursuant to this Agreement (except to the extent that
Distributor's negligence or failure to follow correct instructions received from
Dealer is the cause of such loss,


                                         A-7
<PAGE>

claim, liability, cost or expense); (ii) any redemption or exchange pursuant to
instructions received from Dealer or its partners, affiliates, officers,
directors, employees or agents; or (iii) the breach by Dealer of any of its
representations and warranties specified herein or the Dealer's failure to
comply with the terms and conditions of this Agreement, whether or not such
action, failure, error, omission, misconduct or breach is committed by Dealer or
its predecessor, successor, or affiliate, each current or former partner,
officer, director, employee or agent and each person who controls or is
controlled by Dealer.

          b.   Distributor agrees to indemnify, defend and hold harmless Dealer
and its predecessors, successors and affiliates, each current or former partner,
officer, director, employee or agent, and each person who controls or is
controlled by Dealer from any and all losses, claims, liabilities, costs and
expenses, including attorney fees, that may be assessed against or suffered or
incurred by any of them which arise, and which relate to any untrue statement of
or omission to state a material fact contained in the Prospectus or any written
sales literature or other marketing materials provided by the Distributor to the
Dealer, required to be stated therein or necessary to make the statements
therein not misleading.

          c.   Dealer agrees to notify Distributor, within a reasonable time, of
any claim or complaint or any enforcement action or other proceeding with
respect to Shares offered hereunder against Dealer or its partners, affiliates,
officers, directors, employees or agents, or any person who controls Dealer,
within the meaning of Section 15 of the Securities Act of 1933, as amended.

          d.   Dealer further agrees promptly to send Distributor copies of
(i) any report filed pursuant to NASD Conduct Rule 3070, including, without
limitation quarterly reports filed pursuant to Rule 3070(c), (ii) reports filed
with any other self-regulatory organization in lieu of Rule 3070 reports
pursuant to Rule 3070(e) and (iii) amendments to Dealer's Form BD.

          e.   Each party's obligations under these indemnification provisions
shall survive any termination of this Agreement.

     10.  TERMINATION; AMENDMENT

          a.   In addition to the automatic termination of this Agreement
specified in Section 1.c. of this Agreement, each party to this Agreement may
unilaterally cancel its participation in this Agreement by giving thirty (30)
days prior written notice to the other party.  In addition, each party to this
Agreement may terminate this Agreement immediately by giving written notice to
the other party of that other party's material breach of this Agreement.  Such
notice shall be deemed to have been given and to be effective on the date on
which it was either delivered personally to the other party or any officer or
member thereof, or was mailed postpaid or delivered to a telegraph office for
transmission to the other party's designated person at the addresses shown
herein or in the most recent NASD Manual.

          b.   This Agreement shall terminate immediately upon the appointment
of a Trustee under the Securities Investor Protection Act or any other act of
insolvency by Dealer.

          c.   The termination of this Agreement by any of the foregoing means
shall have no effect upon transactions entered into prior to the effective date
of termination and shall


                                         A-8
<PAGE>

not relieve Dealer of its obligations, duties and indemnities specified in this
Agreement.  A trade placed by Dealer subsequent to its voluntary termination of
this Agreement will not serve to reinstate the Agreement.  Reinstatement, except
in the case of a temporary suspension of Dealer, will only be effective upon
written notification by Distributor.

          d.   This Agreement is not assignable or transferable and will
terminate automatically in the event of its "assignment," as defined in the
Investment Company Act of 1940, as amended and the rules, regulations and
interpretations thereunder.  The Distributor may, however, transfer any of its
duties under this Agreement to any entity that controls or is under common
control with Distributor.

          e.   This Agreement may be amended by Distributor at any time by
written notice to Dealer.  Dealer's placing of an order or accepting payment of
any kind after the effective date and receipt of notice of such amendment shall
constitute Dealer's acceptance of such amendment.

     11.  DISTRIBUTOR'S REPRESENTATIONS AND WARRANTIES

          Distributor represents and warrants that:

                                DISTRIBUTION AGREEMENT


          Agreement made as of June 1, 1998, between Prudential Utility Fund,
Inc. (the Fund), and Prudential Investment Management Services LLC, a Delaware
limited liability company (the Distributor).

                                      WITNESSETH

          WHEREAS, the Fund is registered under the Investment Company Act of
1940, as amended (the Investment Company Act), as a diversified, open-end,
management investment company and it is in the interest of the Fund to offer its
shares for sale continuously;

          WHEREAS, the shares of the Fund may be divided into classes and/or
series (all such shares being referred to herein as Shares) and the Fund
currently is authorized to offer Class A, Class B, Class C and Class Z Shares;

          WHEREAS, the Distributor is a broker-dealer registered under the
Securities Exchange Act of 1934, as amended, and is engaged in the business of
selling shares of registered investment companies either directly or through
other broker-dealers;

          WHEREAS, the Fund and the Distributor wish to enter into an agreement
with each other, with respect to the continuous offering of the Fund's Shares
from and after the date hereof in order to promote the growth of the Fund and
facilitate the distribution of its Shares; and

          WHEREAS, the Fund has adopted a plan (or plans) of distribution
pursuant to Rule 12b-1 under the Investment Company Act with respect to certain
of its classes and/or series of Shares (the Plans) authorizing payments by the
Fund to the Distributor with respect to the distribution of such classes and/or
series of Shares and the maintenance of related shareholder accounts.

          NOW, THEREFORE, the parties agree as follows:

Section 1.  APPOINTMENT OF THE DISTRIBUTOR

          The Fund hereby appoints the Distributor as the principal underwriter
and distributor of the Shares of the Fund to sell Shares to the public on behalf
of the Fund and the Distributor hereby accepts such appointment and agrees to
act hereunder.  The Fund hereby agrees during the term of this Agreement to sell
Shares of the Fund through the Distributor on the terms and conditions set forth
below.

<PAGE>

Section 2.  EXCLUSIVE NATURE OF DUTIES

          The Distributor shall be the exclusive representative of the Fund to
act as principal underwriter and distributor of the Fund's Shares, except that:

          2.1  The exclusive rights granted to the Distributor to sell Shares of
the Fund shall not apply to Shares of the Fund issued in connection with the
merger or consolidation of any other investment company or personal holding
company with the Fund or the acquisition by purchase or otherwise of all (or
substantially all) the assets or the outstanding shares of any such company by
the Fund.

          2.2  Such exclusive rights shall not apply to Shares issued by the
Fund pursuant to reinvestment of dividends or capital gains distributions or
through the exercise of any conversion feature or exchange privilege.

          2.3  Such exclusive rights shall not apply to Shares issued by the
Fund pursuant to the reinstatement privilege afforded redeeming shareholders.


          2.4  Such exclusive rights shall not apply to purchases made through
the Fund's transfer and dividend disbursing agent in the manner set forth in the
currently effective Prospectus of the Fund.  The term "Prospectus" shall mean
the Prospectus and Statement of Additional Information included as part of the
Fund's Registration Statement, as such Prospectus and Statement of Additional
Information may be amended or supplemented from time to time, and the term
"Registration Statement" shall mean the Registration Statement filed by the Fund
with the Securities and Exchange Commission and effective under the Securities
Act of 1933, as amended (Securities Act), and the Investment Company Act, as
such Registration Statement is amended from time to time.

Section 3.  PURCHASE OF SHARES FROM THE FUND

          3.1  The Distributor shall have the right to buy from the Fund on
behalf of investors the Shares needed, but not more than the Shares needed
(except for clerical errors in transmission) to fill unconditional orders for
Shares placed with the Distributor by investors or registered and qualified
securities dealers and other financial institutions (selected dealers).

          3.2  The Shares shall be sold by the Distributor on behalf of the Fund
and delivered by the Distributor or selected dealers, as described in Section
6.4 hereof, to investors at the offering price as set forth in the Prospectus.

          3.3  The Fund shall have the right to suspend the sale of any or all
classes and/or series of its Shares at times when redemption is suspended
pursuant to


                                          2
<PAGE>

the conditions in Section 4.3 hereof or at such other times as may be determined
by the Board.  The Fund shall also have the right to suspend the sale of any or
all classes and/or series of its Shares if a banking moratorium shall have been
declared by federal or New Jersey authorities.

          3.4  The Fund, or any agent of the Fund designated in writing by the
Fund, shall be promptly advised of all purchase orders for Shares received by
the Distributor.  Any order may be rejected by the Fund; provided, however, that
the Fund will not arbitrarily or without reasonable cause refuse to accept or
confirm orders for the purchase of Shares.  The Fund (or its agent) will confirm
orders upon their receipt, will make appropriate book entries and upon receipt
by the Fund (or its agent) of payment therefor, will deliver deposit receipts
for such Shares pursuant to the instructions of the Distributor.  Payment shall
be made to the Fund in New York Clearing House funds or federal funds.  The
Distributor agrees to cause such payment and such instructions to be delivered
promptly to the Fund (or its agent).

Section 4.  REPURCHASE OR REDEMPTION OF SHARES BY THE FUND

          4.1  Any of the outstanding Shares may be tendered for redemption at
any time, and the Fund agrees to repurchase or redeem the Shares so tendered in
accordance with its Articles of Incorporation as amended from time to time, and
in accordance with the applicable provisions of the Prospectus.  The price to be
paid to redeem or repurchase the Shares shall be equal to the net asset value
determined as set forth in the Prospectus.  All payments by the Fund hereunder
shall be made in the manner set forth in Section 4.2 below.

          4.2  The Fund shall pay the total amount of the redemption price as
defined in the above paragraph pursuant to the instructions of the Distributor
on or before the seventh day subsequent to its having received the notice of
redemption in proper form.  The proceeds of any redemption of Shares shall be
paid by the Fund as follows:  (i) in the case of Shares subject to a contingent
deferred sales charge, any applicable contingent deferred sales charge shall be
paid to the Distributor, and the balance shall be paid to or for the account of
the redeeming shareholder, in each case in accordance with applicable provisions
of the Prospectus; and (ii) in the case of all other Shares, proceeds shall be
paid to or for the account of the redeeming shareholder, in each case in
accordance with applicable provisions of the Prospectus.

          4.3  Redemption of any class and/or series of Shares or payment may be
suspended at times when the New York Stock Exchange is closed for other than
customary weekends and holidays, when trading on said Exchange is restricted,
when an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable

Section 5.  DUTIES OF THE FUND

          5.1  Subject to the possible suspension of the sale of Shares as
provided herein, the Fund agrees to sell its Shares so long as it has Shares of
the respective class and/or series available.

          5.2  The Fund shall furnish the Distributor copies of all information,
financial statements and other papers which the Distributor may reasonably
request for use in connection with the distribution of Shares, and this shall
include one certified copy, upon request by the Distributor, of all financial

shall make available to the Distributor such number of copies of its Prospectus
and annual and interim reports as the Distributor shall reasonably request.

          5.3  The Fund shall take, from time to time, but subject to the
necessary approval of the Board and the shareholders, all necessary action to
fix the number of authorized Shares and such steps as may be necessary to
register the same under the Securities Act, to the end that there will be
available for sale such number of Shares as the Distributor reasonably may
expect to sell.  The Fund agrees to file from time to time such amendments,
reports and other documents as may be necessary in order that there will be no
untrue statement of a material fact in the Registration Statement, or necessary
in order that there will be no omission to state a material fact in the
Registration Statement which omission would make the statements therein
misleading.

          5.4  The Fund shall use its best efforts to notify such states as the
Distributor and the Fund may approve of its intention to sell any appropriate
number of its Shares; provided that the Fund shall not be required to amend its
Articles of Incorporation or By-Laws to comply with the laws of any state, to
maintain an office in any state, to change the terms of the offering of its
Shares in any state from the terms set forth in its Registration Statement, to
qualify as a foreign corporation in any state or to consent to service of
process in any state other than with respect to claims arising out of the
offering of its Shares.  Any such notification may be withheld, terminated or
withdrawn by the Fund at any time in its discretion.  As provided in Section 9
hereof, the expense of notification and maintenance of notification shall be
borne by the Fund.  The Distributor shall furnish such information and other
material relating to its affairs and activities as may be required by the Fund
in connection with such notifications.

of the NASD.

Distributor shall inform the Board of the commissions and account servicing fees
with respect to the relevant class and/or series of Shares to be paid by the
Distributor to account executives of the Distributor and to broker-dealers,
financial institutions and investment advisers which have dealer agreements with

therewith, of qualifying the Fund as a broker or dealer, in such states of the
United States or other jurisdictions as shall be selected by the Fund and the
Distributor pursuant to Section 5.4 hereof and the cost and expense payable to
each such state for continuing notification therein until the Fund decides to

the Securities Act or under common law or otherwise, but only to the extent that
such liability or expense incurred by the Fund, its

Directors or officers or such controlling person resulting from such claims or
demands shall arise out of or be based upon any alleged untrue statement of a
material fact contained in information furnished by the Distributor to the Fund
for use in the Registration Statement or Prospectus or shall arise out of or be
based upon any alleged omission to state a material fact in connection with such
information required to be stated in the Registration Statement or Prospectus or
necessary to make such information not misleading.  The Distributor's agreement
to indemnify the Fund, its officers and Directors and any such controlling
person as aforesaid, is expressly conditioned upon the Distributor's being

                            Distribution and Service Plan
                                   (CLASS A SHARES)

                                     INTRODUCTION


     The Distribution and Service Plan (the Plan) set forth below which is
designed to conform to the requirements of Rule 12b-1 under the Investment
Company Act of 1940 (the Investment Company Act) and Rule 2830 of the Conduct
Rules of the National Association of Securities Dealers, Inc. (NASD) has been
adopted by Prudential Utility Fund, Inc. (the Fund) and by Prudential Investment
Management Services LLC,  the Fund's distributor (the Distributor).

     The Fund has entered into a distribution agreement pursuant to which the
Fund will employ the Distributor to distribute Class A shares issued by the Fund
(Class A shares).  Under the Plan, the Fund intends to pay to the Distributor,
as compensation for its services, a distribution and service fee with respect to
Class A shares.

     A majority of the Board of Directors of the Fund, including a majority of
those Directors who are not "interested persons" of the Fund (as defined in the
Investment Company Act) and who have no direct or indirect financial interest in
the operation of this Plan or any agreements related to it (the Rule 12b-1
Directors), have determined by votes cast in person at a meeting called for the
purpose of voting on this Plan that there is a reasonable likelihood that
adoption and continuation of this Plan will benefit the Fund and its
shareholders.  Expenditures under this Plan by the Fund for Distribution
Activities (defined below) are primarily intended to result in the sale of Class
A shares


                                          1
<PAGE>

of the Fund within the meaning of paragraph (a)(2) of Rule 12b-1 promulgated
under the Investment Company Act.

     The purpose of the Plan is to create incentives to the Distributor and/or
other qualified broker-dealers and their account executives to provide
distribution assistance to their customers who are investors in the Fund, to
defray the costs and expenses associated with the preparation, printing and
distribution of prospectuses and sales literature and other promotional and
distribution activities and to provide for the servicing and maintenance of
shareholder accounts.

                                       THE PLAN

     The material aspects of the Plan are as follows:

1.   DISTRIBUTION ACTIVITIES

     The Fund shall engage the Distributor to distribute Class A shares of the
Fund and to service shareholder accounts using all of the facilities of the
Distributor's distribution network, including sales personnel and branch office
and central support systems, and also using such other qualified broker-dealers
and financial institutions as the Distributor may select, including Prudential
Securities Incorporated (Prudential Securities) and Pruco Securities Corporation
(Prusec). Services provided and activities undertaken to distribute Class A
shares of the Fund are referred to herein as "Distribution Activities."

2.   PAYMENT OF SERVICE FEE

     The Fund shall pay to the Distributor as compensation for providing
personal service and/or maintaining shareholder accounts a service fee of .25 of
1% per annum of the average daily net assets of the Class A shares (service
fee).  The Fund shall


                                          2
<PAGE>

calculate and accrue daily amounts payable by the Class A shares of the Fund
hereunder and shall pay such amounts monthly or at such other intervals as the
Board of Directors may determine.

3.   PAYMENT FOR DISTRIBUTION ACTIVITIES

     The Fund shall pay to the Distributor as compensation for its services a
distribution fee, together with the service fee (described in Section 2 hereof),
of .30 of 1% per annum of the average daily net assets of the Class A shares of
the Fund for the performance of Distribution Activities.  The Fund shall
calculate and accrue daily amounts payable by the Class A shares of the Fund
hereunder and shall pay such amounts monthly or at such other intervals as the
Board of Directors may determine.  Amounts payable under the Plan shall be
subject to the limitations of Rule 2830 of the NASD Conduct Rules.

     Amounts paid to the Distributor by the Class A shares of the Fund will not
be used to pay the distribution expenses incurred with respect to any other
class of shares of the Fund except that distribution expenses attributable to
the Fund as a whole will be allocated to the Class A shares according to the
ratio of the sales of Class A shares to the total sales of the Fund's shares
over the Fund's fiscal year or such other allocation method approved by the
Board of Directors.  The allocation of distribution expenses among classes will
be subject to the review of the Board of Directors.

     The Distributor shall spend such amounts as it deems appropriate on
Distribution Activities which include, among others:


     (a)  sales commissions and trailer commissions paid to, or on account of,
          account executives of the Distributor;


                                          3
<PAGE>

     (b)  indirect and overhead costs of the Distributor associated with
          Distribution Activities, including central office and branch expenses;

     (c)  amounts paid to Prudential Securities or Prusec for performing
          services under a selected dealer agreement between Prudential
          Securities or Prusec and the Distributor for sale of Class A shares of
          the Fund, including sales commissions, trailer commissions paid to, or
          on account of, agents and indirect and overhead costs associated with
          Distribution Activities;

     (d)  advertising for the Fund in various forms through any available
          medium, including the cost of printing and mailing Fund prospectuses,
          statements of additional information and periodic financial reports
          and sales literature to persons other than current shareholders of
          the Fund; and

     (e)  sales commissions (including trailer commissions) paid to, or on
          account of, broker-dealers and financial institutions (other than
          Prudential Securities or Prusec) which have entered into selected
          dealer agreements with the Distributor with respect to Class A shares
          of the Fund.

4.   QUARTERLY REPORTS; ADDITIONAL INFORMATION

     An appropriate officer of the Fund will provide to the Board of Directors 
of the Fund for review, at least quarterly, a written report specifying in
reasonable detail the amounts expended for Distribution Activities (including
payment of the service fee) and the purposes for which such expenditures were
made in compliance with the requirements of Rule 12b-1.  The Distributor will
provide to the Board of Directors of the Fund such additional information as the
Board shall from time to time reasonably request, including information about
Distribution Activities undertaken or to be undertaken by the Distributor.

     The Distributor will inform the Board of Directors of the Fund of the
commissions and account servicing fees to be paid by the Distributor to account
executives of the


                                          4
<PAGE>

Distributor and to broker-dealers and financial institutions which have selected
dealer agreements with the Distributor.

5.   EFFECTIVENESS; CONTINUATION

     The Plan shall not take effect until it has been approved by a vote of a
majority of the outstanding voting securities (as defined in the Investment
Company Act) of the Class A shares of the Fund.

     If approved by a vote of a majority of the outstanding voting securities of
the Class A shares of the Fund, the Plan shall, unless earlier terminated in
accordance with its terms, continue in full force and effect thereafter for so
long as such continuance is specifically approved at least annually by a
majority of the Board of Directors of the Fund and a majority of the Rule 12b-1
Directors by votes cast in person at a meeting called for the purpose of voting
on the continuation of the Plan.

6.   TERMINATION

     This Plan may be terminated at any time, without the payment of any
penalty, by  a majority of the Rule 12b-1 Directors, or by vote of a majority of
the outstanding voting securities (as defined in the Investment Company Act) of
the Class A shares of the Fund, or by the Distributor, on sixty (60) days'
written notice to the other party.  This Plan shall automatically terminate in
the event of its assignment.

7.   AMENDMENTS

     The Plan may not be amended to change the combined service and distribution
fees to be paid as provided for in Sections 2 and 3 hereof so as to increase
materially the amounts payable under this Plan unless such amendment shall be
approved by the vote of a majority of the outstanding voting securities (as
defined in the Investment


                                          5
<PAGE>

Company Act) of the Class A shares of the Fund.  All material amendments of the
Plan shall be approved by a majority of the Board of Directors of the Fund and a
majority of the Rule 12b-1 Directors by votes cast in person at a meeting called
for the purpose of voting on the Plan.

8.   RULE 12b-1 DIRECTORS

     While the Plan is in effect, the selection and nomination of the Directors
shall be committed to the discretion of the Rule 12b-1 Directors.

9.   RECORDS

     The Fund shall preserve copies of the Plan and any related agreements and
all reports made pursuant to Section 4 hereof, for a period of not less than six
years from the date of effectiveness of the Plan, such agreements or reports,
and for at least the first two years in an easily accessible place.

                                 Amended and Restated
                            Distribution and Service Plan
                                   (CLASS C SHARES)


                                     INTRODUCTION

     The Distribution and Service Plan (the Plan) set forth below which is
designed to conform to the requirements of Rule 12b-1 under the Investment
Company Act of 1940 (the Investment Company Act) and Rule 2830 of the Conduct
Rules of the National Association of Securities Dealers, Inc. (NASD) has been
adopted by Prudential Utility Fund, Inc. (the Fund) and by Prudential Investment
Management Services LLC, the Fund's distributor (the Distributor).

     The Fund has entered into a distribution agreement pursuant to which the
Fund will employ the Distributor to distribute Class C shares issued by the Fund
(Class C shares).  Under the Plan, the Fund wishes to pay to the Distributor, as
compensation for its services, a distribution and service fee with respect to
Class C shares.

     A majority of the Board of Directors of the Fund, including a majority who
are not "interested persons" of the Fund (as defined in the Investment Company
Act) and who have no direct or indirect financial interest in the operation of
this Plan or any agreements related to it (the Rule 12b-1 Directors), have
determined by votes cast in person at a meeting called for the purpose of voting
on this Plan that there is a reasonable likelihood that adoption and
continuation of this Plan will benefit the Fund and its shareholders.
Expenditures under this Plan by the Fund for Distribution Activities (defined
below) are primarily intended to result in the sale of Class C shares


                                          1
<PAGE>

of the Fund within the meaning of paragraph (a)(2) of Rule 12b-1 promulgated
under the Investment Company Act.

     The purpose of the Plan is to create incentives to the Distributor and/or
other qualified broker-dealers and their account executives to provide
distribution assistance to their customers who are investors in the Fund, to
defray the costs and expenses associated with the preparation, printing and
distribution of prospectuses and sales literature and other promotional and
distribution activities and to provide for the servicing and maintenance of
shareholder accounts.

                                     (the Fund)


                  AMENDED AND RESTATED PLAN PURSUANT TO RULE 18F-3

     The Fund hereby adopts this plan pursuant to Rule 18f-3 under the
Investment Company Act of 1940 (the 1940 Act), setting forth the separate
arrangement and expense allocation of each class of shares in the Fund.  Any
material amendment to this plan is subject to prior approval of the Board of
Directors, including a majority of the independent Directors.


                                CLASS CHARACTERISTICS

CLASS A SHARES: Class A shares are subject to a high initial sales charge and a
                    distribution and/or service fee pursuant to Rule 12b-1 under
                    the 1940 Act (Rule 12b-1 fee) not to exceed .30 of 1% per
                    annum of the average daily net assets of the class.  The
                    initial sales charge is waived or reduced for certain
                    eligible investors.

CLASS B SHARES: Class B shares are not subject to an initial sales charge but
                    aresubject to a high contingent deferred sales charge
                    (declining from 5% to zero over a six-year period) which
                    will be imposed on certain redemptions and a Rule 12b-1 fee
                    not to exceed 1% per annum of the average daily net assets
                    of the class.  The contingent deferred sales charge is
                    waived for certain eligible investors.  Class B shares
                    automatically convert to Class A shares approximately seven
                    years after purchase.

CLASS C SHARES: Class C shares issued before November 2, 1998 are not subject to
                    an initial sales charge but are subject to a 1% contingent
                    deferred sales charge which will be imposed on certain
                    redemptions within the first 12 month after purchase and a
                    Rule 12b-1 fee not to exceed 1% per annum of the average
                    daily net assets of the class.  Class C shares issued on or
                    after November 2, 1998 are subject to a low initial sales
                    charge and a 1% contingent deferred sales charge which will
                    be imposed on certain redemptions within the first 18 months
                    after purchase and a Rule 12b-1 fee not to exceed 1% per
                    annum of the average daily net assets of the class.

<PAGE>

CLASS Z SHARES:  Class Z shares are not subject to either an initial or
                    contingent deferred sales charge, nor are they subject to
                    any Rule 12b-1 fee.

                            INCOME AND EXPENSE ALLOCATIONS

     Income, any realized and unrealized capital gains and losses, and expenses
     not allocated to a particular class of the Fund will be allocated to each
     class of the Fund on the basis of the net asset value of that class in
     relation to the net asset value of the Fund.

                             DIVIDENDS AND DISTRIBUTIONS

     Dividends and other distributions paid by the Fund to each class of 
     shares, to the extent paid, will be paid on the same day and at the same 
     time, and will be determined in the same manner and will be in the same 
     amount, except that the amount of the dividends and other distributions 
     declared and paid by a particular class of the Fund may be different 
     from that paid by another class of the Fund because of Rule 12b-1 fees 
     and other expenses borne exclusively by that class.

                                  EXCHANGE PRIVILEGE

     Holders of Class A Shares, Class B Shares, Class C Shares and Class Z
     Shares shall have such exchange privileges as set forth in the Fund's
     current prospectus.  Exchange privileges may vary among classes and among
     holders of a Class.

                                CONVERSION FEATURES

     Class B shares will automatically convert to Class A shares on a 
     quarterly basis approximately seven years after purchase.  Conversions 
     will be effected at relative net asset value without the imposition of 
     any additional sales charge.

                                       GENERAL

A.   Each class of shares shall have exclusive voting rights on any matter
     submitted to shareholders that relates solely to its arrangement and shall
     have separate voting rights on any matter submitted to shareholders in
     which the interests of one class differ from the interests of any other
     class.

B.   On an ongoing basis, the Directors, pursuant to their fiduciary
     responsibilities under the 1940 Act and otherwise, will monitor the Fund
     for the existence of any material conflicts among the interests of its
     several classes.  The Directors,


                                          2
<PAGE>

     including a majority of the independent Directors, shall take such action
     as is reasonably necessary to eliminate any such conflicts that may
     develop.  Prudential Investments Fund Management LLC, the Fund's Manager,
     will be responsible for reporting any potential or existing conflicts to
     the Directors.

C.   For purposes of expressing an opinion on the financial statements of the 
     Fund, the methodology and procedures for calculating the net asset value 
     and dividends/distributions of the Fund's several classes and the proper 
     allocation of income and expenses among such classes will be examined 
     annually by the Fund's independent auditors who, in performing such 
     examination, shall consider the factors set forth in the relevant 
     auditing standards adopted, from time to time, by the American Institute 
     of Certified Public Accountants.
