                                FUND HIGHLIGHTS
 
   The following summary is intended to highlight certain information
 contained in this Prospectus and is qualified in its entirety by the more
 detailed information appearing elsewhere herein.
 
 
 WHAT IS PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.?
 
   Prudential National Municipals Fund, Inc. is a mutual fund. A mutual fund
 pools the resources of investors by selling its shares to the public and
 investing the proceeds of such sale in a portfolio of securities designed
 to achieve its investment objective. Technically, the Fund is an open-end,
 diversified management investment company.
 
 WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
 
   The investment objective of the Fund is to seek a high level of current
 income exempt from federal income taxes. In attempting to achieve this
 objective, under normal circumstances, the Fund intends to invest
 substantially all, and in any event at least 80%, of its total assets in
 Municipal Bonds and Municipal Notes. There can be no assurance that the
 Fund's objective will be achieved. See "How the Fund Invests--Investment
 Objective and Policies" at page 8.
 
 WHAT ARE THE FUND'S RISK FACTORS AND SPECIAL CHARACTERISTICS?
 
   The Fund's portfolio will consist primarily of carefully selected long-
 term Municipal Bonds of medium quality. While the Fund's investment adviser
 will not be limited by the ratings assigned by the rating services, the
 Municipal Bonds in which the Fund's portfolio will be principally invested
 will be rated A and Baa by Moody's Investors Service (Moody's) and A and
 BBB by Standard & Poor's Ratings Group (S&P) or comparably rated by any
 other Nationally Recognized Statistical Rating Organization (NRSRO) or, if
 not rated, will be, in the judgment of the investment adviser, of
 substantially comparable quality. See "How the Fund Invests--Investment
 Objective and Policies" at page 8. The Fund may also engage in various
 hedging and return enhancement strategies, including using derivatives,
 which may be considered speculative and may result in higher risks and
 costs to the Fund. See "How the Fund Invests--Hedging and Return
 Enhancement Strategies" at page 10.
 
 WHO MANAGES THE FUND?
 
   Prudential Mutual Fund Management LLC (PMF or the Manager) is the Manager
 of the Fund and is compensated for its services at an annual rate of .50 of
 1% of the Fund's average daily net assets up to and including $250 million,
 .475 of 1% of the next $250 million, .45 of 1% of the next $500 million,
 .425 of 1% of the next $250 million, .40 of 1% of the next $250 million and
 .375 of 1% of the Fund's average daily net assets in excess of $1.5
 billion. As of January 31, 1996, PMF served as manager or administrator to
 62 investment companies, including 40 mutual funds, with aggregate assets
 of approximately $55.8 billion. The Prudential Investment Corporation,
 which does business under the name of Prudential Investments (PI, the
 Subadviser or the investment adviser), furnishes investment advisory
 services in connection with the management of the Fund under a Subadvisory
 Agreement with PMF. See "How the Fund is Managed--Manager" at page 19.
 
 WHO DISTRIBUTES THE FUND'S SHARES?
 
   Prudential Securities Incorporated (Prudential Securities or PSI), a
 major securities underwriter and securities and commodities broker, acts as
 the Distributor of the Fund's Class A, Class B and Class C shares and is
 paid an annual distribution and service fee which is currently being
 charged at the rate of .10 of 1% of the average daily net assets of the
 Class A shares, at the rate of .50 of 1% of the average daily net assets of
 the Class B shares and which is currently being charged at the rate of .75
 of 1% of the average daily net assets of the Class C shares. See "How the
 Fund is Managed--Distributor" at page 20.
 
 
                                       2
<PAGE>
 
 
WHAT IS THE MINIMUM INVESTMENT?
 
  The minimum initial investment for Class A and Class B shares is $1,000 per
class and $5,000 for Class C shares. The minimum subsequent investment is $100.
There is no minimum investment requirement for certain employee savings plans
or custodial accounts for the benefit of minors. For purchases made through the
Automatic Savings Accumulation Plan, the minimum initial and subsequent
investment is $50. See "Shareholder Guide--How to Buy Shares of the Fund" at
page 27 and "Shareholder Guide--Shareholder Services" at page 36.
 
HOW DO I PURCHASE SHARES?
 
  You may purchase shares of the Fund through Prudential Securities, Pruco
Securities Corporation (Prusec) or directly from the Fund, through its transfer
agent, Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), at the
net asset value per share (NAV) next determined after receipt of your purchase
order by the Transfer Agent or Prudential Securities plus a sales charge which
may be imposed either (i) at the time of purchase (Class A shares) or (ii) on a
deferred basis (Class B or Class C shares). See "How the Fund Values its
Shares" at page 23 and "Shareholder Guide--How to Buy Shares of the Fund" at
page 27.
 
WHAT ARE MY PURCHASE ALTERNATIVES?
 
  The Fund offers three classes of shares:
 
 . Class A Shares:Sold with an initial sales charge of up to 3% of the offering
            price.
 
 . Class B Shares: Sold without an initial sales charge but are subject to a
                  contingent deferred sales charge or CDSC (declining from 5%
                  to zero of the lower of the amount invested or the redemption
                  proceeds) which will be imposed on certain redemptions made
                  within six years of purchase. Although Class B shares are
                  subject to higher ongoing distribution-related expenses than
                  Class A shares, Class B shares will automatically convert to
                  Class A shares (which are subject to lower ongoing
                  distribution-related expenses) approximately seven years
                  after purchase.
 
 . Class C Shares: Sold without an initial sales charge and, for one year after
                  purchase, are subject to a 1% CDSC on redemptions. Like Class
                  B shares, Class C shares are subject to higher ongoing
                  distribution-related expenses than Class A shares but, unlike
                  Class B Shares, Class C Shares do not convert to another
                  class.
 
  See "Shareholder Guide--Alternative Purchase Plan" at page 28.
 
HOW DO I SELL MY SHARES?
 
  You may redeem shares of the Fund at any time at the NAV next determined
after Prudential Securities or the Transfer Agent receives your sell order.
However, the proceeds of redemptions of Class B and Class C shares may be
subject to a CDSC. See "Shareholder Guide--How to Sell Your Shares" at page 31.
 
HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
 
  The Fund expects to declare daily and pay monthly dividends of net investment
income and make distributions of net capital gains, if any, at least annually.
Dividends and distributions will be automatically reinvested in additional
shares of the Fund at NAV without a sales charge unless you request that they
be paid to you in cash. See "Taxes, Dividends and Distributions" at page 24.

  You would pay the following expenses on a
   $1,000 investment, assuming (1) 5% annual
   return, and (2) redemption at the end of

 The above example is based on data for the Fund's fiscal year ended Decem-
 ber 31, 1996. The example should not be considered a representation of past
 or future expenses. Actual expenses may be greater or less than those
 shown.
 The purpose of this table is to assist investors in understanding the vari-
 ous costs and expenses that an investor in the Fund will bear, whether di-
 rectly or indirectly. For more complete descriptions of the various costs
 and expenses, see "How the Fund Is Managed." "Other Expenses" include oper-
 ating expenses of the Fund, such as directors' and professional fees, reg-
 istration fees, reports to shareholders, transfer agency and custodian
 fees.
 --------
  * Class B shares will automatically convert to Class A shares
    approximately seven years after purchase. See "Shareholder Guide--
    Conversion Feature--Class B Shares."
 ** Based on expenses incurred during the fiscal year ended December 31,
    1996, without taking into account the management fee waiver. At the
    current level of management fee waiver (.05%), Management Fees and Total
    Fund Operating Expenses would be .43% and .68%, respectively, for Class
    A shares, .43% and 1.08%, respectively, for Class B shares, .43% and
    1.33%, respectively, for Class C shares.
  + Pursuant to rules of the National Association of Securities Dealers,
    Inc., the aggregate initial sales charges, deferred sales charges and
    asset-based sales charges on shares of the Fund may not exceed 6.25% of
    the total gross sales, subject to certain exclusions. This 6.25%
    limitation is imposed on each class of the Fund rather than on a per
    shareholder basis. Therefore, long-term shareholders of the Fund may pay
    more in total sales charges than the economic equivalent of 6.25% of
    such shareholders' investment in such shares. See "How the Fund is
    Managed--Distributor."
 ++ Although the Class A and Class C Distribution and Service Plans provide
    that the Fund may pay a distribution fee of up to .30 of 1% per annum
    and 1% per annum of the average daily net assets of the Class A and
    Class C shares, respectively, the Distributor has agreed to limit its
    distribution fees with respect to Class A and Class C shares of the Fund
    to no more than .10 of 1% and .75 of 1% of the average daily net asset
    value of the Class A and Class C shares, respectively, for the year
    ending December 31, 1997. Total operating expenses (before management
    fee waiver) and without such limitations would be .93% and 1.63% for
    Class A and Class C shares, respectively. See "How the Fund is Managed--
    Distributor."

                             HOW THE FUND INVESTS
 
 
INVESTMENT OBJECTIVE AND POLICIES
 
  THE INVESTMENT OBJECTIVE OF THE FUND IS TO SEEK A HIGH LEVEL OF CURRENT
INCOME EXEMPT FROM FEDERAL INCOME TAXES. IN ATTEMPTING TO ACHIEVE THIS
OBJECTIVE, UNDER NORMAL CIRCUMSTANCES THE FUND INTENDS TO INVEST SUBSTANTIALLY
ALL, AND IN ANY EVENT AT LEAST 80%, OF ITS TOTAL ASSETS IN MUNICIPAL BONDS AND
MUNICIPAL NOTES. THERE CAN BE NO ASSURANCE THAT SUCH OBJECTIVE WILL BE
ACHIEVED. See "Investment Objective and Policies" in the Statement of
Additional Information.
 
  THE FUND'S INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE, MAY
NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE FUND'S
OUTSTANDING VOTING SECURITIES AS DEFINED IN THE INVESTMENT COMPANY ACT OF
1940, AS AMENDED (THE INVESTMENT COMPANY ACT). FUND POLICIES THAT ARE NOT
FUNDAMENTAL MAY BE MODIFIED BY THE BOARD OF DIRECTORS.
 
  THE MUNICIPAL BONDS IN WHICH THE FUND MAY INVEST INCLUDE GENERAL OBLIGATION
AND LIMITED OBLIGATION OR REVENUE BONDS. GENERAL OBLIGATION BONDS ARE SECURED
BY THE ISSUER'S PLEDGE OF ITS FAITH, CREDIT AND TAXING POWER FOR THE PAYMENT
OF PRINCIPAL AND INTEREST, WHEREAS REVENUE BONDS ARE PAYABLE ONLY FROM THE
REVENUES DERIVED FROM A PARTICULAR FACILITY OR CLASS OF FACILITIES OR IN SOME
CASES, FROM THE PROCEEDS OF A SPECIAL EXCISE OR OTHER SPECIFIC REVENUE SOURCE.
THE MUNICIPAL NOTES IN WHICH THE FUND MAY INVEST INCLUDE TAX, REVENUE AND BOND
ANTICIPATION NOTES WHICH ARE ISSUED TO OBTAIN FUNDS FOR VARIOUS PUBLIC
PURPOSES.
 
  Interest on certain Municipal Bonds and Municipal Notes may be subject to
the federal alternative minimum tax. From time to time the Fund may purchase
Municipal Bonds and Municipal Notes that are "private activity bonds" (as
defined in the Internal Revenue Code), the interest on which is a tax
preference subject to the alternative minimum tax. See "Taxes, Dividends and
Distributions".
 
  THE FUND'S PORTFOLIO WILL CONSIST PRIMARILY OF CAREFULLY SELECTED LONG-TERM
MUNICIPAL BONDS OF MEDIUM QUALITY. WHILE THE FUND'S INVESTMENT ADVISER WILL
NOT BE LIMITED BY THE RATINGS ASSIGNED BY THE RATING SERVICES, THE MUNICIPAL
BONDS IN WHICH THE FUND'S PORTFOLIO WILL BE PRINCIPALLY INVESTED WILL BE RATED
A AND BAA BY MOODY'S INVESTORS SERVICE (MOODY'S) AND A AND BBB BY STANDARD &
POOR'S RATINGS GROUP (S&P) OR COMPARABLY RATED BY ANY OTHER NATIONALLY
RECOGNIZED STATISTICAL RATING ORGANIZATION (NRSRO) OR, IF NOT RATED, WILL BE,
IN THE JUDGMENT OF THE INVESTMENT ADVISER, OF SUBSTANTIALLY COMPARABLE
QUALITY. Bonds rated BBB by S&P normally exhibit adequate payment protection
parameters, but in the event of adverse market conditions are more likely to
lead to a weakened capacity to pay principal and interest than bonds in the A
category. Bonds rated Baa by Moody's are considered "medium grade"
obligations. They are neither highly protected nor poorly secured. Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable
over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well. A more
complete description of these and other Municipal Bond and Note ratings is
contained in Appendix A to the Statement of Additional Information.
 
                                       8
<PAGE>
 
  As of December 31, 1996, the composition of the Fund's portfolio by rating
category was as follows:
 
<TABLE>
<CAPTION>
                 PERCENTAGE OF
     RATINGS   TOTAL INVESTMENTS
     -------   -----------------
     <S>       <C>
     AAA/Aaa         60.2%
     AA/Aa           12.1%
     A/A              7.2%
     BBB/Baa         18.9%
     B/B              --
     CCC/Caa          --
     CC/Ca            --
     C/C              --
     Unrated          1.6%
</TABLE>
 
  BECAUSE ISSUERS OF MEDIUM QUALITY MUNICIPAL BONDS MAY CHOOSE NOT TO HAVE
THEIR OBLIGATIONS RATED, IT IS POSSIBLE THAT A SUBSTANTIAL PORTION OF THE
FUND'S PORTFOLIO MAY CONSIST OF OBLIGATIONS WHICH ARE NOT RATED. The market
for rated bonds is usually broader than that for non-rated bonds, which may
result in less flexibility in disposal of such non-rated bonds.
 
  THE FUND MAY ALSO ACQUIRE MUNICIPAL BONDS WHICH HAVE BEEN RATED BELOW MEDIUM
QUALITY BY THE RATING SERVICES IF, IN THE JUDGMENT OF THE FUND'S INVESTMENT
ADVISER, THE BONDS HAVE THE CHARACTERISTICS OF MEDIUM QUALITY OBLIGATIONS. In
determining whether Municipal Bonds which are not rated or which have been
rated below medium quality by the rating services have the characteristics of
rated Municipal Bonds of medium quality, the investment adviser will rely upon
information from various sources, including, if available, reports by the
rating services, research, analysis and appraisals of brokers and dealers and
the views of the Fund's directors and others regarding economic developments
and the creditworthiness of particular issuers.
 
  MUNICIPAL BONDS OF MEDIUM QUALITY ARE SUBJECT TO FLUCTUATION IN VALUE AS A
RESULT OF CHANGING ECONOMIC CIRCUMSTANCES AS WELL AS CHANGES IN INTEREST
RATES. THUS, WHILE MEDIUM QUALITY OBLIGATIONS WILL GENERALLY PROVIDE A HIGHER
YIELD THAN DO HIGH QUALITY MUNICIPAL BONDS OF SIMILAR MATURITIES, THEY ARE
SUBJECT TO A GREATER DEGREE OF MARKET FLUCTUATION WITH LESS CERTAINTY OF THE
ISSUER'S CONTINUING ABILITY TO MEET THE PAYMENTS OF PRINCIPAL AND INTEREST
WHEN DUE AND MAY HAVE SPECULATIVE CHARACTERISTICS NOT PRESENT IN BONDS OF
HIGHER QUALITY. IN ADDITION, OBLIGATIONS WITH LONGER MATURITIES (E.G., 20
YEARS OR MORE) GENERALLY OFFER BOTH HIGHER YIELDS AND GREATER EXPOSURE TO
MARKET FLUCTUATION FROM CHANGES IN INTEREST RATES THAN DO THOSE WITH SHORTER
MATURITIES. CONSEQUENTLY, SHARES OF THE FUND MAY NOT BE SUITABLE FOR PERSONS
WHO CANNOT ASSUME THE SOMEWHAT GREATER RISKS OF CAPITAL DEPRECIATION INVOLVED
IN SEEKING HIGHER TAX-EXEMPT YIELDS.
 
  In recent years, there has been a narrowing of the yield spreads between
higher and lower quality Municipal Bonds and a reduction in the supply of
medium grade Municipal Bonds. As a result of these changing conditions in the
municipal securities markets, the investment adviser has invested a
substantial portion of the Fund's assets in higher quality Municipal Bonds.
The investment adviser intends to invest in medium grade Municipal Bonds to
the extent market conditions warrant.
 
  THE INTEREST RATES PAYABLE ON CERTAIN MUNICIPAL BONDS AND NOTES ARE NOT
FIXED AND MAY FLUCTUATE BASED UPON CHANGES IN MARKET RATES. MUNICIPAL BONDS
AND NOTES OF THIS TYPE ARE CALLED "VARIABLE RATE" OBLIGATIONS. The interest
rate payable on a variable rate obligation is adjusted either at predesignated
intervals or whenever there is a change in the market rate of interest on
which the interest rate payable is based. Other features may include the right
whereby the Fund may demand prepayment of the principal amount of the
 
                                       9
<PAGE>
 
obligation prior to its stated maturity (a demand feature) and the right of
the issuer to prepay the principal amount prior to maturity. The principal
benefit of a variable rate obligation is that the interest rate adjustment
minimizes changes in the market value of the obligation. As a result, the
purchase of variable rate obligations should enhance the ability of the Fund
to maintain a stable net asset value per share and to sell an obligation prior
to maturity at a price approximating the full principal amount of the
obligation. The payment of principal and interest by issuers of certain
Municipal Bonds and Notes purchased by the Fund may be guaranteed by letters
of credit or other credit facilities offered by banks or other financial
institutions. Such guarantees will be considered in determining whether a
Municipal Bond or Note meets the Fund's investment quality requirements.
 
  THE FUND MAY ALSO INVEST IN INVERSE FLOATERS. An inverse floater is a debt
instrument with a floating or variable interest rate that moves in the
opposite direction of the interest rate on another security or the value of an
index. Changes in the interest rate on the other security or index inversely
affect the residual interest rate paid on the inverse floater, with the result
that the inverse floater's price will be considerably more volatile than that
of a fixed rate bond. The market for inverse floaters is relatively new.
 
  SOME MUNICIPAL SECURITIES, SUCH AS ZERO COUPON MUNICIPAL SECURITIES, DO NOT
PAY CURRENT INTEREST BUT ARE PURCHASED AT A DISCOUNT FROM THEIR FACE VALUES.
The discount approximates the total amount of interest the security will
accrue and compound over the period until maturity or the particular interest
payment date at a rate of interest reflecting the market rate of the security
at the time of issuance. Zero coupon securities do not require the periodic
payment of interest. These investments benefit the issuer by mitigating its
need for cash to meet debt service, but also require a higher rate of return
to attract investors who are willing to defer receipt of cash. These
investments may experience greater volatility in market value than securities
that make regular payments of interest.
 
  THE FUND MAY BE ABLE TO REDUCE THE RISK OF FLUCTUATIONS IN ASSET VALUE
CAUSED BY CHANGES IN INTEREST RATES BY HEDGING ITS PORTFOLIO THROUGH THE USE
OF FINANCIAL FUTURES. During or in anticipation of a decline in interest
rates, the Fund may purchase futures contracts to hedge against subsequent
purchases of long-term bonds at higher prices. During or in anticipation of an
increase in interest rates, the Fund may hedge its portfolio securities by
selling futures contracts for the purpose of limiting the exposure of its
portfolio to the resulting decrease in value. There are risks associated with
hedging transactions and there can be no assurance that hedges will have the
intended result. See "Hedging and Return Enhancement Strategies" below.
 
  ALSO, THE FUND MAY PURCHASE SECONDARY MARKET INSURANCE ON MUNICIPAL BONDS
AND NOTES WHICH IT HOLDS OR ACQUIRES. Although the fee for secondary market
insurance will reduce the yield of the insured Bonds and Notes, such insurance
would be reflected in the market value of the municipal obligation purchased
and may enable the Fund to dispose of a defaulted obligation at a price
similar to that of comparable municipal obligations which are not in default.
 
  Insurance is not a substitute for the basic credit of an issuer, but
supplements the existing credit and provides additional security therefor.
While insurance coverage for the Municipal Bonds and Notes held by the Fund
reduces credit risk by providing that the insurance company will make timely
payment of principal and interest if the issuer defaults on its obligation to
make such payment, it does not afford protection against fluctuation in the
price, i.e., the market value, of the municipal obligations caused by changes
in interest rates and other factors, nor in turn against fluctuations in the
net asset value of the shares of the Fund.
 
HEDGING AND RETURN ENHANCEMENT STRATEGIES
 
  THE FUND MAY ALSO ENGAGE IN VARIOUS PORTFOLIO STRATEGIES, INCLUDING
DERIVATIVES, TO REDUCE CERTAIN RISKS OF ITS INVESTMENTS AND TO ATTEMPT TO
ENHANCE RETURN, BUT NOT FOR SPECULATION. THE FUND, AND THUS THE INVESTOR, MAY
LOSE MONEY THROUGH ANY UNSUCCESSFUL USE OF THESE STRATEGIES. These strategies
currently include the purchase of put or tender options on Municipal Bonds and
Notes and the purchase and sale of
 
                                      10
<PAGE>
 
financial futures contracts and options thereon and municipal bond index
futures contracts. The Fund's ability to use these strategies may be limited
by market conditions, regulatory limits and tax considerations and there can
be no assurance that any of these strategies will succeed. See "Investment
Objective and Policies--Additional Investment Policies" in the Statement of
Additional Information. New financial products and risk management techniques
continue to be developed and the Fund may use these new investments and
techniques to the extent consistent with its investment objective and
policies.

AND NOTES. PUTS OR TENDER OPTIONS GIVE THE FUND THE RIGHT TO SELL SECURITIES
HELD IN THE FUND'S PORTFOLIO AT A SPECIFIED EXERCISE PRICE ON A SPECIFIED
DATE. Puts or tender options may be acquired to reduce the volatility of the
market value of securities subject to puts or tender options compared to the
volatility of similar securities not subject to puts. The acquisition of a put
or tender option may involve an additional cost to the Fund compared to the
cost of securities with similar credit ratings, stated maturities and interest
coupons but without applicable puts. Such increased cost may be paid either by
way of an initial or periodic premium for the put or by way of a higher
purchase price for securities to which the put is attached. In addition, there
is a credit risk associated with the purchase of puts or tender options in
that the issuer of the put or tender option may be unable to meet its
obligation to purchase the underlying security. Accordingly, the Fund will
acquire puts or tender options under the following circumstances: (1) the put
or tender option is written by the issuer of the underlying security and such
security is rated within the 4 highest quality grades as determined by
Moody's, S&P or other NRSRO; (2) the put or tender option is written by a
person other than the issuer of the underlying security and such person has
securities outstanding which are rated within such 4 highest quality grades;
or (3) the put or tender option is backed by a letter of credit or similar
financial guarantee issued by a person having securities outstanding which are
rated within the 2 highest quality grades of such rating services.
 
  THE FUND ANTICIPATES BEING AS FULLY INVESTED AS PRACTICABLE IN MUNICIPAL
BONDS AND NOTES; HOWEVER, BECAUSE THE FUND DOES NOT INTEND TO INVEST IN
TAXABLE OBLIGATIONS, THERE MAY BE OCCASIONS WHEN, AS A RESULT OF MATURITIES OF
PORTFOLIO SECURITIES OR SALES OF FUND SHARES OR IN ORDER TO MEET ANTICIPATED
REDEMPTION REQUESTS, THE FUND MAY HOLD CASH WHICH IS NOT EARNING INCOME. IN
ADDITION, THERE MAY BE OCCASIONS WHEN, IN ORDER TO RAISE CASH TO MEET
REDEMPTIONS, THE FUND MIGHT BE REQUIRED TO SELL SECURITIES AT A LOSS.
 
  Unlike many issues of common and preferred stock and corporate bonds which
are traded between brokers acting as agent for their customers on securities
exchanges, Municipal Bonds and Notes are customarily purchased from or sold to
dealers who are selling or buying for their own account. There are no
requirements that most Municipal Bonds and Notes be registered with or
qualified for sale by federal or state securities regulators. Since there are
large numbers of Municipal Bond and Note issues of many different issuers,
most issues do not trade on any single day. On the other hand, most issues are
always marketable, since a major dealer will normally, on request, bid for any
issue, other than obscure ones. Regional municipal securities dealers are
frequently more willing to bid on issues of municipalities in their geographic
area.
 
  ALTHOUGH ALMOST ALL MUNICIPAL BONDS AND NOTES ARE MARKETABLE, THE STRUCTURE
OF THE MARKET INTRODUCES ITS OWN ELEMENT OF RISK; A SELLER MAY FIND, ON
OCCASION, THAT DEALERS ARE UNWILLING TO MAKE BIDS FOR CERTAIN ISSUES THAT THE
SELLER CONSIDERS REASONABLE. IF THE SELLER IS FORCED TO SELL, HE OR SHE MAY
REALIZE A CAPITAL LOSS THAT WOULD NOT HAVE BEEN NECESSARY IN DIFFERENT
CIRCUMSTANCES. BECAUSE THE NET ASSET VALUE OF THE FUND'S SHARES REFLECTS THE
DEGREE OF WILLINGNESS OF DEALERS TO BID FOR MUNICIPAL BONDS AND NOTES, THE
PRICE OF THE FUND'S SHARES MAY BE SUBJECT TO GREATER FLUCTUATION THAN SHARES
OF OTHER INVESTMENT COMPANIES WITH DIFFERENT INVESTMENT POLICIES. SEE "NET
ASSET VALUE" IN THE STATEMENT OF ADDITIONAL INFORMATION.

  The ratings of Moody's, S&P and other NRSROs represent each service's
opinion as to the quality of the Municipal Bonds or Notes rated. It should be
emphasized that ratings are general and are not absolute standards of quality
or guarantees as to the creditworthiness of an issuer. Subsequent to its
purchase by the Fund, an issue of Municipal Bonds or Notes may cease to be
rated, or its ratings may be reduced. Neither event requires the elimination
of that obligation from the Fund's portfolio, but will be a factor in
determining whether the Fund should continue to hold that issue in its
portfolio.
 
  FROM TIME TO TIME, PROPOSALS HAVE BEEN INTRODUCED BEFORE CONGRESS FOR THE
PURPOSE OF RESTRICTING OR ELIMINATING THE FEDERAL INCOME TAX EXEMPTION FOR
INTEREST ON MUNICIPAL BONDS AND NOTES AND FOR PROVIDING STATE AND LOCAL
GOVERNMENTS WITH FEDERAL CREDIT ASSISTANCE. REEVALUATION OF THE FUND'S
INVESTMENT OBJECTIVE AND STRUCTURE MIGHT BE NECESSARY IN THE FUTURE DUE TO
MARKET CONDITIONS WHICH MAY RESULT FROM FUTURE CHANGES IN THE TAX LAWS.
 
FUTURES CONTRACTS AND OPTIONS THEREON
 
  THE FUND MAY ENGAGE IN TRANSACTIONS IN FUTURES CONTRACTS FOR RETURN
ENHANCEMENT AND RISK MANAGEMENT PURPOSES AS WELL AS TO REDUCE THE RISK OF
FLUCTUATIONS IN THE VALUE OF ITS ASSETS CAUSED BY INTEREST RATE CHANGES BY
HEDGING ITS PORTFOLIO THROUGH THE USE OF FINANCIAL FUTURES AND OPTIONS THEREON
TRADED ON A COMMODITIES EXCHANGE OR BOARD OF TRADE.
 
  FUTURES CONTRACTS
 
  The Fund may enter into futures contracts for the purchase or sale of debt
securities and financial indices (collectively, interest rate futures
contracts) in accordance with the Fund's investment objective. A "purchase" of
a futures contract (or a "long" futures position) means the assumption of a
contractual obligation to acquire a specified quantity of the securities
underlying the contract at a specified price at a specified future date. A
"sale" of a futures contract (or a "short" futures position) means the
assumption of a contractual obligation to deliver a specified quantity of the
securities underlying the contract at a specified price at a specified future
date. At the time a futures contract is purchased or sold, the Fund is
required to deposit cash, U.S. Government securities or other liquid
unencumbered assets with a futures commission merchant or in a segregated
custodial account representing between approximately 1 1/2% to 5% of the
contract amount, called "initial margin." Thereafter, the futures contract
will be valued daily and the payment in cash of "maintenance" or "variation
margin" may be required, resulting in the Fund paying or receiving cash that
reflects any decline or increase in the contract's value, a process known as
"mark-to-market."
 
  Some futures contracts by their terms may call for the actual delivery or
acquisition of the underlying assets and other futures contracts must be "cash
settled." In most cases the contractual obligation is extinguished before the
expiration of the contract by buying (to offset an earlier sale) or selling
(to offset an earlier purchase) an identical futures contract calling for
delivery or acquisition in the same month. The purchase (or sale) of an
offsetting futures contract is referred to as a "closing transaction."
 
  LIMITATIONS ON THE PURCHASE AND SALE OF FUTURES CONTRACTS AND RELATED
OPTIONS
 
  CFTC LIMITS. In accordance with Commodity Futures Trading Commission (CFTC)
regulations, the Fund is not permitted to purchase or sell interest rate
futures contracts or options thereon for return enhancement or risk management
purposes if immediately thereafter the sum of the amounts of initial margin
deposits on a Fund's existing futures and premiums paid for options on futures
exceed 5% of the liquidation value of such Fund's total assets (the 5% CFTC
limit). This restriction does not apply to the purchase and sale of interest
rate futures contracts and options thereon for bona fide hedging purposes.
 
                                      12
<PAGE>
 
  SEGREGATION REQUIREMENTS. To the extent the Fund enters into futures
contracts, it is required by the SEC to maintain a segregated asset account
with its custodian or a futures commissions merchant sufficient to cover the
Fund's obligations with respect to such futures contracts, which will consist
of cash, U.S. government securities or other liquid, unencumbered assets from
their portfolios in an amount equal to the difference between the fluctuating
market value of such futures contracts and the aggregate value of the initial
margin deposited by the Fund with the Custodian or a futures commission
merchant with respect to such futures contracts. Offsetting the contract by
another identical contract eliminates the segregation requirement.
 
  With respect to options on futures, there are no segregation requirements
for options that are purchased and owned by the Fund. However, written
options, since they involve potential obligations of the Fund, may require
segregation of Fund assets if the options are not "covered" as described below
under "Options on Futures Contracts." If the Fund writes a call option that is
not "covered," it must segregate and maintain with the custodian for the term
of the option cash, U.S. government securities or other liquid, unencumbered
assets equal to the fluctuating value of the optioned futures. If a Fund
writes a put option that is not "covered," the segregated amount would have to
be at all times equal in value to the exercise price of the put (less any
initial margin deposited by the Fund with the Custodian or a futures
commission merchant with respect to such option).
 
  USE OF INTEREST RATE FUTURES CONTRACTS
 
  Interest rate futures contracts will be used for bona fide hedging, risk
management and return enhancement purposes.
 
  POSITION HEDGING. The Fund might sell interest rate futures contracts to
protect the Fund against a rise in interest rates which would be expected to
decrease the value of debt securities which the Fund holds. This would be
considered a bona fide hedge and, therefore, is not subject to the 5% CFTC
limit. For example, if interest rates are expected to increase, the Fund might
sell futures contracts on debt securities, the values of which historically
have closely correlated or are expected to closely correlate to the values of
the Fund's portfolio securities. Such a sale would have an effect similar to
selling an equivalent value of the Fund's portfolio securities. If interest
rates increase, the value of the Fund's portfolio securities will decline, but
the value of the futures contracts to the Fund will increase at approximately
an equivalent rate thereby keeping the net asset value of the Fund from
declining as much as it otherwise would have. The Fund could accomplish
similar results by selling debt securities with longer maturities and
investing in debt securities with shorter maturities when interest rates are
expected to increase. However, since the futures market may be more liquid
than the cash market, the use of futures contracts as a hedging technique
would allow the Fund to maintain a defensive position without having to sell
portfolio securities. If in fact interest rates decline rather than rise, the
value of the futures contract will fall but the value of the bonds should rise
and should offset all or part of the loss. If futures contracts are used to
hedge 100% of the bond position and correlate precisely with the bond
positions, there should be no loss or gain with a rise (or fall) in interest
rates. However, if only 50% of the bond position is hedged with futures, then
the value of the remaining 50% of the bond position would be subject to change
because of interest rate fluctuations. Whether the bond positions and futures
contracts correlate is a significant risk factor.
 
  ANTICIPATORY POSITION HEDGING. Similarly, when it is expected that interest
rates may decline and the Fund intends to acquire debt securities, the Fund
might purchase interest rate futures contracts. The purchase of futures
contracts for this purpose would constitute an anticipatory hedge against
increases in the price of debt securities (caused by declining interest rates)
which the Fund subsequently acquires and would normally qualify as a bona fide
hedge not subject to the 5% CFTC limit. Since fluctuations in the value of
appropriately selected futures contracts should approximate that of the debt
securities that would be purchased, the Fund could take advantage of the
anticipated rise in the cost of the debt securities without actually buying
them. Subsequently,
 
                                      13
<PAGE>
 
the Fund could make the intended purchases of the debt securities in the cash
market and concurrently liquidate the futures positions.
 
  RISK MANAGEMENT AND RETURN ENHANCEMENT. The Fund might sell interest rate
futures contracts covering bonds. This has the same effect as selling bonds in
the portfolio and holding cash and reduces the duration of the portfolio.
(Duration measures the price sensitivity of the portfolio to interest rates.
The longer the duration, the greater the impact of interest rate changes on
the portfolio's price.) This should lessen the risks associated with a rise in
interest rates. In some circumstances, this may serve as a hedge against a
loss of principal, but is usually referred to as an aspect of risk management.
 
  The Fund might buy interest rate futures contracts covering bonds with a
longer maturity than its portfolio average. This would tend to increase the
duration and should increase the gain in the overall portfolio if interest
rates fall. This is often referred to as risk management rather than hedging
but, if it works as intended, has the effect of increasing principal value. It
if does not work as intended because interest rates rise instead of fall, the
loss will be greater than would otherwise have been the case. Futures
contracts used for these purposes are not considered bona fide hedges and,
therefore, are subject to the 5% CFTC limit.
 
  OPTIONS ON FUTURES CONTRACTS
 
  The Fund may enter into options on futures contracts for certain bona fide
hedging, risk management and return enhancement purposes. This includes the
ability to purchase put and call options and write (i.e., sell) "covered" put
and call options on futures contracts that are traded on commodity and futures
exchanges.
 
  If the Fund purchased an option on a futures contract, it has the right but
not the obligation, in return for the premium paid, to assume a position in a
futures contract (a long position if the option is a call or a short position
if the option is a put) at a specified exercise price at any time during the
option exercise period.
 
  Unlike purchasing an option, which is similar to purchasing insurance to
protect against a possible rise or fall of security prices or currency values,
the writer or seller of an option undertakes an obligation upon exercise of
the option to either buy or sell the underlying futures contract at the
exercise price. A writer of a call option has the obligation upon exercise to
assume a short futures position and a writer of a put option has the
obligation to assume a long futures position. 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. If there is no balance in the writer's margin
account, the option is "out of the money" and will not be exercised. The Fund,
as the writer, has income in the amount it was paid for the option. If there
is a margin balance, the Fund will have a loss in the amount of the amount of
the balance less the premium it was paid for writing the option.
 
  When the Fund writes a put or call option on futures contracts, the option
must either be "covered" or, to the extent not "covered," will be subject to
segregation requirements. The Fund will be considered "covered" with respect
to a call option it writes on a futures contract if the Fund owns the
securities or currency which is deliverable under the futures contract or an
option to purchase that futures contract having a strike price equal to or
less than the strike price of the "covered" option. A Fund will be considered
"'covered" with respect to a put option it writes on a futures contract if it
owns an option to sell that futures contract having a strike price equal to or
greater than the strike price of the "covered" option.
 
                                      14
<PAGE>
 
 To the extent the Fund is not "covered" as described above with respect to
written options, it will segregate and maintain with its custodian for the
term of the option cash or liquid securities as described above under--
"Segregation Requirements."
 
  USE OF OPTIONS ON FUTURES CONTRACTS
 
  Options on interest rate futures contracts would be used for bona fide
hedging, risk management and return enhancement purposes.
 
  POSITION HEDGING. The Fund may purchase put options on interest rate or
currency futures contracts to hedge its portfolio against the risk of a
decline in the value of the debt securities it owns as a result of rising
interest rates.
 
  ANTICIPATORY HEDGING. The Fund may also purchase call options on futures
contracts as a hedge against an increase in the value of securities the Fund
might intend to acquire as a result of declining interest rates.
 
  Writing a put option on a futures contract may serve as a partial
anticipatory hedge against an increase in the value of debt securities the
Fund might intend to acquire. If the futures price at expiration of the option
is above the exercise price, the Fund retains the full amount of the option
premium which provides a partial hedge against any increase that may have
occurred in the price of the debt securities the Fund intended to acquire. If
the market price of the underlying futures contract is below the exercise
price when the option is exercised, the Fund would incur a loss, which may be
wholly or partially offset by the decrease in the value of the securities the
Fund might intend to acquire.
 
  Whether options on interest rate futures contracts are subject to or exempt
from the 5% CFTC limit depends on whether the purpose of the options
constitutes a bona fide hedge.
 
  RISK MANAGEMENT AND RETURN ENHANCEMENT. Writing a put option that does not
relate to securities the Fund intends to acquire would be a return enhancement
strategy which would result in a loss if interest rates rise.
 
  Similarly, writing a covered call option on a futures contract is also a
return enhancement strategy. If the market price of the underlying futures
contract at expiration of a written call option is below the exercise price,
the Fund would retain the full amount of the option premium increasing the
income of the Fund. If the futures price when the option is exercised is above
the exercise price, however, the Fund would sell the underlying securities
which was the "cover" for the contract and incur a gain or loss depending on
the cost basis for the underlying assets.
 
  Writing a covered call option as in any return enhancement strategy can also
be considered a partial hedge against a decrease in the value of a Fund's
portfolio securities. The amount of the premium received acts as a partial
hedge against any decline that may have occurred in the Fund's debt
securities.
 
  RISKS RELATING TO TRANSACTIONS IN FUTURES CONTRACTS AND OPTIONS THEREON
 
  The Fund's ability to establish and close out positions in futures contracts
and options on futures contracts would be impacted by the liquidity of these
markets. Although the Fund generally would purchase or sell only those futures
contracts and options thereon for which there appeared to be a liquid market,
there is no assurance that a liquid market on an exchange will exist for any
particular futures contract or option at any
 
                                      15
<PAGE>
 
particular time. In the event no liquid market exists for a particular futures
contract or option thereon in which the Fund maintains a position, it would
not be possible to effect a closing transaction in that contract or to do so
at a satisfactory price and the Fund would have to either make or take
delivery under the futures contract or, in the case of a written call option,
wait to sell the underlying securities until the option expired or was
exercised, or, in the case of a purchased option, exercise the option. In the
case of a futures contract or an option on a futures contract which the Fund
had written and which the Fund was unable to close, the Fund would be required
to maintain margin deposits on the futures contract or option and to make
variation margin payments until the contract is closed.
 
  Risks inherent in the use of these strategies include (1) dependence on the
investment adviser's ability to predict correctly movements in the direction
of interest rates, securities prices and markets; (2) imperfect correlation
between the price of futures contracts and options thereon and movement in the
prices of the securities being hedged; (3) the fact that the 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 possible need to defer closing out
certain hedged positions to avoid adverse tax consequences; and (6) the
possible inability of the Fund to sell a portfolio security at a time that
otherwise would be favorable for it to do so. In the event it did sell the
security and eliminated its "cover," it would have to replace its "cover" with
an appropriate futures contract or option or segregate securities with the
required value, as described under--"Segregation Requirements."
 
  Although futures prices themselves have the potential to be extremely
volatile, in the case of any strategy involving interest rate futures
contracts and options thereon when the Subadviser's expectations are not met,
assuming proper adherence to the segregation requirement, the volatility of
the Fund as a whole should be no greater than if the same strategy had been
pursued in the cash market.
 
  Exchanges on which futures and related options trade may impose limits on
the positions that the Fund may take in certain circumstances. In addition,
the hours of trading of financial futures contracts and options thereon 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.
 
  Pursuant to the requirements of the Commodity Exchange Act, as amended (the
Commodity Exchange Act), all futures contracts and options thereon must be
traded on an exchange. Since a clearing corporation effectively acts as the
counterparty on every futures contract and option thereon, the counterparty
risk depends on the strength of the clearing or settlement corporation
associated with the exchange. Additionally, although the exchanges provide a
means of closing out a position previously established, there can be no
assurance that a liquid market will exist for a particular contract at a
particular time. In the case of options on futures, 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.
 
  There can be no assurance that the Fund's use of futures contracts and
related options will be successful and the Fund may incur losses in connection
with its purchase and sale of future contracts and related options.

OTHER INVESTMENTS AND POLICIES
 
  WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
 
  The Fund may purchase municipal obligations on a "when-issued" or "delayed
delivery basis," in each case without limit. When municipal obligations are
offered on a when-issued or delayed delivery basis, the price and coupon rate
are fixed at the time the commitment to purchase is made, but delivery and
payment for such securities take place at a later date. During the period
between purchase and settlement, no interest accrues to the purchaser. In the
case of purchases by the Fund, the price that the Fund is required to pay on
the settlement date may be in excess of the market value of the municipal
obligations on that date. While securities may be sold prior to the settlement
date, the Fund intends to purchase these securities with the purpose of
actually acquiring them unless a sale would be desirable for investment
reasons. At the time the Fund makes the commitment to purchase a municipal
obligation on a when-issued basis, it will record the transaction and reflect
the value of the obligation, each day, in determining its net asset value.
This value may fluctuate from day to day in the same manner as values of
municipal obligations otherwise held by the Fund. If the seller defaults in
the sale, the Fund could fail to realize the appreciation, if any, that had
occurred. The Fund will establish a segregated account with its Custodian in
which it will maintain cash, U.S. Government Securities, equity securities or
other liquid unencumbered assets, marked-to-market daily equal in value to its
commitments for when-issued or delayed delivery securities.
 
  MUNICIPAL LEASE OBLIGATIONS
 
  THE FUND MAY ALSO INVEST IN MUNICIPAL LEASE OBLIGATIONS. A MUNICIPAL LEASE
OBLIGATION IS A MUNICIPAL SECURITY THE INTEREST ON AND PRINCIPAL OF WHICH IS
PAYABLE OUT OF LEASE PAYMENTS MADE BY THE PARTY LEASING THE FACILITIES
FINANCED BY THE ISSUE. Typically, municipal lease obligations are issued by a
state or municipal financing authority to provide funds for the construction
of facilities (e.g., schools, dormitories, office buildings or prisons). The
facilities are typically used by the state or municipality pursuant to a lease
with a financing authority. Certain municipal lease obligations may trade
infrequently. Accordingly, the investment adviser will monitor the liquidity
of municipal lease obligations under the supervision of the Board of
Directors. Municipal lease obligations will not be considered illiquid for
purposes of the Fund's 15% limitation on illiquid securities provided the
investment adviser determines that there is a readily available market for
such securities. See "Illiquid Securities" below and "Investment Objective and
Policies--Illiquid Securities" in the Statement of Additional Information.
 
  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 or contractual restrictions on resale and securities that are not readily
marketable. Securities, including municipal lease obligations, that have a
readily available market are not considered illiquid for the purposes of this
limitation. The investment adviser will monitor the liquidity of such
securities under the supervision of the Directors. See "Investment Objectives
and Policies--Illiquid Securities" in the Statement of Additional Information.
Repurchase agreements subject to demand are deemed to have a maturity equal to
the notice period.
 
  INVESTMENTS IN SECURITIES OF OTHER INVESTMENT COMPANIES
 
  The Fund may invest up to 10% of its total assets in shares of other
investment companies. To the extent that the Fund does invest in securities of
other investment companies, shareholders of the Fund may be subject to
duplicate management and advisory fees.
 
                                      17
<PAGE>
 
  BORROWING
 
  The Fund may borrow an amount equal to no more than 33 1/3% of the value of
its total assets (calculated when the loan is made) from banks for temporary,
extraordinary or emergency purposes or for the clearance of transactions. The
Fund may pledge up to 33 1/3% of its total assets to secure these borrowings.
However, the Fund will not purchase portfolio securities when borrowings
exceed 5% of the value of the Fund's total assets.
 
PORTFOLIO MANAGEMENT TECHNIQUES
 
  In seeking to achieve the Fund's investment objective, the Fund's investment
adviser will cause the Fund to purchase securities which it believes represent
the best values then currently available in the marketplace. Such values are a
function of yield, maturity, issue classification and quality characteristics,
coupled with expectations regarding the economy, movements in the general
level and term structure of interest rates, political developments and
variations in the supply of funds available for investment in the tax-exempt
market relative to the demand for funds placed upon it. The following are some
of the more important management techniques which will be utilized by the
Fund's investment adviser.
 
  ADJUSTMENT OF MATURITIES
 
  The investment adviser will seek to anticipate movements in interest rates
and will adjust the maturity distribution of the portfolio accordingly. Longer
term securities have ordinarily yielded more than shorter term securities.
From time to time, however, the normal yield relationships between longer and
shorter term securities have been reversed. In addition, longer term
securities have historically been subject to greater and more rapid price
fluctuation. The investment adviser will be free to take advantage of price
volatility in order to attempt to increase the Fund's net asset value by
making appropriate sales and purchases of portfolio securities.
 
  ISSUE AND QUALITY CLASSIFICATION
 
  Securities with the same general quality rating and maturity
characteristics, but which vary according to the purpose for which they were
issued, often tend to trade at different yields. Similarly, securities issued
for similar purposes and with the same general maturity characteristics, but
which vary according to the creditworthiness of their respective issuers, tend
to trade at different yields. These yield differentials tend to fluctuate in
response to political and economic developments as well as temporary
imbalances in normal supply and demand relationships. The investment adviser
monitors these fluctuations closely, and will adjust portfolio positions in
various issue and quality classifications according to the value disparities
brought about by these yield relationship fluctuations.
 
INVESTMENT RESTRICTIONS
 
  The Fund is subject to certain investment restrictions which, like its
investment objective, constitute fundamental policies. Fundamental policies
cannot be changed without the approval of the holders of a majority of the
Fund's outstanding voting securities, as defined in the Investment Company
Act. See "Investment Restrictions" in the Statement of Additional Information.

  FEE WAIVER AND SUBSIDY
 
  Effective January 1, 1995, PMF voluntarily agreed to waive .05 of 1% of its
management fee. After the waiver, the management fee is .45 of 1% of the
Fund's average daily net assets up to and including $250 million, .425 of 1%
of the next $250 million, .40 of 1% of the next $500 million, .375 of 1% of
the next $250 million, .35 of 1% of the next $250 million and .325 of 1% of
the Fund's average daily net assets in excess of $1.5 billion. PMF may
hereafter agree, from time to time, to further waive or modify any waiver of
its management fee and subsidize certain operating expenses of the Fund. The
Fund is not required to reimburse PMF for such management fee waiver or
expense subsidy. Fee waivers and expense subsidies will increase the Fund's
yield and total return. See "Fund Expenses."
 
DISTRIBUTOR
 
  PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR PSI), GATEWAY
CENTER THREE, NEWARK, NEW JERSEY 07102-4077 (PRUDENTIAL SECURITIES OR PSI), IS
A CORPORATION ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND SERVES AS
THE DISTRIBUTOR OF THE SHARES OF THE FUND. IT IS AN INDIRECT, WHOLLY-OWNED
SUBSIDIARY OF PRUDENTIAL.
 
  UNDER SEPARATE DISTRIBUTION AND SERVICE PLANS (THE CLASS A PLAN, THE CLASS B
PLAN AND THE CLASS C PLAN, EACH A PLAN, AND COLLECTIVELY, THE PLANS) ADOPTED
BY THE FUND UNDER RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT AND A
DISTRIBUTION AGREEMENT (THE DISTRIBUTION AGREEMENT), PRUDENTIAL SECURITIES
(THE DISTRIBUTOR) INCURS THE EXPENSES OF DISTRIBUTING THE FUND'S CLASS A,
CLASS B AND CLASS C SHARES. These expenses include commissions and account
servicing fees paid to, or on account of, financial advisers of Prudential
Securities and representatives of Pruco Securities Corporation (Prusec), an
affiliated broker-dealer, commissions and account servicing fees paid to, or
on account of, other broker-dealers or financial institutions (other than
national banks) 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 Prudential Securities
and Prusec associated with the sale of Fund shares, including lease, utility,
communications and sales promotion expenses. The State of Texas requires that
shares of the Fund may be sold in that state only by dealers or other
financial institutions which are registered there as broker-dealers.
 
  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.
 
  UNDER THE CLASS A PLAN, THE FUND MAY PAY PRUDENTIAL SECURITIES 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 ASSET VALUE OF THE CLASS A
SHARES. The Class A Plan provides that (i) 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 (ii) total
distribution fees (including the service fee of .25 of 1%) may not exceed .30
of 1% of the average daily net assets of the Class A shares. It is expected
that in the case of Class A shares, proceeds from the distribution fee will be
used primarily to pay account servicing fees to financial advisers. Prudential
Securities has agreed to limit its distribution-related fees payable under the
Class A Plan to .10 of 1% of the average daily net assets of the Class A
shares for the fiscal year ending December 31, 1997.
 
 
                                      20
<PAGE>
 
  UNDER THE CLASS B AND CLASS C PLANS, THE FUND MAY PAY PRUDENTIAL SECURITIES
FOR ITS DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS B AND CLASS C
SHARES AT AN ANNUAL RATE OF UP TO .50 OF 1% AND UP TO 1% OF THE AVERAGE DAILY
NET ASSETS OF THE CLASS B AND CLASS C SHARES, RESPECTIVELY. The Class B Plan
provides for the payment to Prudential Securities of (i) an asset-based sales
charge of up to .50 of 1% of the average daily net assets of the Class B
shares, and (ii) a service fee of up to .25 of 1% of the average daily net
assets of the Class B shares; provided that the total distribution-related fee
does not exceed .50 of 1%. The Class C Plan provides for the payment to
Prudential Securities of (i) an asset-based sales charge of up to .75 of 1% of
the average daily net assets of the Class C shares, and (ii) a service fee of
up to .25 of 1% of the average daily net assets of the Class C shares. The
service fee is used to pay for personal service and/or the maintenance of
shareholder accounts. Prudential Securities has agreed to limit its
distribution-related fees payable under the Class C Plan to .75 of 1% of the
average daily net assets of the Class C shares for the fiscal year ending
December 31, 1997. Prudential Securities also receives contingent deferred
sales charges from certain redeeming shareholders. See "Shareholder Guide--How
to Sell Your Shares--Contingent Deferred Sales Charge."
 
  For the fiscal year ended December 31, 1996, the Fund paid distribution
expenses of .10 of 1%, .50 of 1% and .75 of 1% of the average net assets of
the Class A, Class B and Class C shares, respectively. The Fund records all
payments made under the Plans as expenses in the calculation of net investment
income. See "Distributor" in the Statement of Additional Information.
 
  Distribution expenses attributable to the sale of shares of the Fund will be
allocated to each such class based upon the ratio of sales of each such class
to the sales of all shares of the Fund other than expenses allowable to a
particular class. The distribution fee and sales charge of one class will not
be used to subsidize the sale of another class.
 
  Each Plan provides that it shall continue in effect from year to year
provided that a majority of the Board of Directors of the Fund, including a
majority of the 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 the Plan or any agreement related to
the Plan (the Rule 12b-1 Directors), vote annually to continue the Plan. Each
Plan may be terminated at any time by vote of a majority of the Rule 12b-1
Directors or of a majority of the outstanding shares of the applicable class
of the Fund. The Fund will not be obligated to pay expenses incurred under any
plan if it is terminated or not continued.
 
  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 out of its own resources to dealers (including Prudential
Securities) and other persons who distribute shares of the Fund. Such payments
may be calculated by reference to the net asset value of shares sold by such
persons or otherwise.
 
  The Distributor is subject to the rules of the National Association of
Securities Dealers, Inc. (NASD) governing maximum sales charges. See
"Distributor" in the Statement of Additional Information.
 
  On October 21, 1993, PSI entered into an omnibus settlement with the SEC,
state securities regulators (with the exception of the Texas Securities
Commissioner who joined the settlement on January 18, 1994) and the NASD to
resolve allegations that from 1980 through 1990 PSI sold certain limited
partnership interests in violation of securities laws to persons for whom such
securities were not suitable and misrepresented the safety, potential returns
and liquidity of these investments. Without admitting or denying the
allegations asserted against it, PSI consented to the entry of an SEC
Administrative Order which stated that PSI's conduct violated the federal
 
                                      21
<PAGE>
 
securities laws, directed PSI to cease and desist from violating the federal
securities laws, pay civil penalties, and adopt certain remedial measures to
address the violations.
 
  Pursuant to the terms of the SEC settlement, PSI agreed to the imposition of
a $10,000,000 civil penalty, established a settlement fund in the amount of
$330,000,000 and procedures to resolve legitimate claims for compensatory
damages by purchasers of the partnership interests. PSI has agreed to provide
additional funds, if necessary, for the purpose of the settlement fund. PSI's
settlement with the state securities regulators included an agreement to pay a
penalty of $500,000 per jurisdiction. PSI consented to a censure and to the
payment of a $5,000,000 fine in settling the NASD action.
 
  In October 1994, a criminal complaint was filed with the United States
Magistrate for the Southern District of New York alleging that PSI committed
fraud in connection with the sale of certain limited partnership interests in
violation of federal securities laws. An agreement was simultaneously filed to
defer prosecution of these charges for a period of three years from the
signing of the agreement, provided that PSI complies with the terms of the
agreement. If, upon the completion of the three year period, PSI has complied
with the terms of the agreement, no prosecution will be instituted by the
United States for the offenses charged in the complaint. If on the other hand,
during the course of the three year period, PSI violates the terms of the
agreement, the U.S. Attorney can then elect to pursue these charges. Under the
terms of the agreement, PSI agreed, among other things, to pay an additional
$330,000,000 into the fund established by the SEC to pay restitution to
investors who purchased certain PSI limited partnership interests.
 
  For more detailed information concerning the foregoing matters, see
"Distributor" in the Statement of Additional Information, a copy of which may
be obtained at no cost by calling 1-800-225-1852.
 
  The Fund is not affected by PSI's financial condition and is an entirely
separate legal entity from PSI, which has no beneficial ownership therein and
the Fund's assets which are held by State Street Bank and Trust Company, an
independent custodian, are separate and distinct from PSI.
 
PORTFOLIO TRANSACTIONS
 
  Prudential Securities may also act as a broker or futures commission
merchant for the Fund, provided that the commissions, fees or other
remuneration it receives are fair and reasonable. See "Portfolio Transactions

<PAGE>
 
 
                        HOW THE FUND VALUES ITS SHARES
 
 
  THE FUND'S NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING ITS
LIABILITIES FROM ITS ASSETS AND DIVIDING THE REMAINDER BY THE NUMBER OF
OUTSTANDING SHARES. NAV IS CALCULATED SEPARATELY FOR EACH CLASS. THE BOARD OF
DIRECTORS HAS FIXED THE SPECIFIC TIME OF DAY FOR THE COMPUTATION OF THE FUND'S
NAV TO BE AS OF 4:15 P.M., NEW YORK TIME.
 
  Portfolio securities are valued based on market quotations or, if not
readily available, at fair value as determined in good faith under procedures
established by the Fund's Board of Directors. See "Net Asset Value" in the
Statement of Additional Information.
 
  The Fund will compute its NAV once daily on days that the New York Stock
Exchange is open for trading except on days on which no orders to purchase,
sell or redeem shares have been received by the Fund or days on which changes
in the value of the Fund's portfolio securities do not materially affect the
NAV. The New York Stock Exchange is closed on the following holidays: New
Year's 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. 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. It is expected,
however, that the NAV per share of the three 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.
 
 
                      HOW THE FUND CALCULATES PERFORMANCE
 
 
  FROM TIME TO TIME THE FUND MAY ADVERTISE ITS "YIELD," "TAX EQUIVALENT
YIELD," AND "TOTAL RETURN" (INCLUDING "AVERAGE ANNUAL" TOTAL RETURN AND
"AGGREGATE" TOTAL RETURN) IN ADVERTISEMENTS OR SALES LITERATURE. YIELD, TAX
EQUIVALENT YIELD, AND TOTAL RETURN ARE CALCULATED SEPARATELY FOR CLASS A,
CLASS B AND CLASS C SHARES. These figures are based on historical earnings and
are not intended to indicate future performance. The "yield" refers to the
income generated by an investment in the Fund over a 30-day period. This
income is then "annualized"; that is, the amount of income generated by the
investment during that 30-day period is assumed to be generated each 30-day
period for twelve periods and is shown as a percentage of the investment. The
income earned on the investment is also assumed to be reinvested at the end of
the sixth 30-day period. The "tax equivalent yield" is calculated similarly to
the "yield," except that the yield is increased using a stated income tax rate
to demonstrate the taxable yield necessary to produce an after-tax yield
equivalent to the Fund. The "total return" shows what an investment in the
Fund would have earned over a specified period of time (i.e., one, five or ten
years or since inception of the Fund) assuming that all distributions and
dividends by the Fund were reinvested on the reinvestment dates during the
period and less all recurring fees. The "aggregate" total return reflects
actual performance over a stated period of time. "Average annual" total return
is a hypothetical rate of return that, if achieved annually, would have
produced the same aggregate total return
 
                                      23
<PAGE>
 
if performance had been constant over the entire period. Average annual total
return smooths out variations in performance and takes into account any
applicable initial or contingent deferred sales charges. Neither "average
annual" total return nor "aggregate" total return takes into account any
federal or state income taxes which may be payable upon redemption. The Fund
also may include comparative performance information in advertising or
marketing the Fund's shares. Such performance information may include data
from Lipper Analytical Services, Inc., Morningstar Publications, Inc., other
industry publications, business periodicals, and market indices. See
"Performance Information" in the Statement of Additional Information. Further
performance information is contained in the Fund's annual and semi-annual
reports to shareholders, which may be obtained without charge. See
"Shareholder Guide--Shareholder Services--Reports to Shareholders."
 
                      TAXES, DIVIDENDS AND DISTRIBUTIONS
 
 
TAXATION OF THE FUND
 
  THE FUND HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, THE
FUND WILL NOT BE SUBJECT TO FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME
AND CAPITAL GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS. SEE
"TAXES, DIVIDENDS AND DISTRIBUTIONS" IN THE STATEMENT OF ADDITIONAL
INFORMATION.
 
  Gain or loss realized by the Fund from the sale of securities generally will
be treated as capital gain or loss; however, gain from the sale of certain
securities (including municipal obligations) will be treated as ordinary
income to the extent of any "market discount." Market discount generally is
the difference, if any, between the price paid by the Fund for the security
and the principal amount of the security (or, in the case of a security issued
at an original issue discount, the revised issued price of the security). The
market discount rule does not apply to any security that was acquired by the
Fund at its original issue price.
 
TAXATION OF SHAREHOLDERS
 
  Distributions out of net investment income, to the extent attributable to
interest received on tax-exempt securities, are exempt from federal income tax
when paid to shareholders. Distributions of other net investment income and
net short-term capital gains in excess of net long-term capital losses will be
taxable as ordinary income to the shareholder whether or not reinvested. Any
net long-term capital gains (i.e., the excess of net long-term capital gains
over net short-term capital losses) distributed to shareholders will be
taxable as such to the shareholders, whether or not reinvested and regardless
of the length of time a shareholder has owned his or her shares. The maximum
long-term capital gains rate for individuals is currently 28% and the maximum
tax rate for ordinary income is 39.6%. The maximum long-term capital gains
rate for corporate shareholders is currently the same as the 35% maximum
corporate tax rate for ordinary income.
 
  Interest on certain "private activity" tax-exempt obligations issued on or
after August 8, 1986, is a preference item for purposes of the alternative
minimum tax for both individual and corporate shareholders. In the event that
the Fund invests in such obligations, the portion of an exempt-interest
dividend of the Fund that is allocable to such municipal obligations will be
treated as a preference item to shareholders for purposes of the alternative
minimum tax. In addition, a portion of the exempt-interest dividends received
by corporate shareholders with respect to interest on tax-exempt obligations,
whether or not private activity bonds, will be taken into account in computing
the alternative minimum tax. See "Taxes, Dividends and Distributions" in the
Statement of Additional Information.
 
                                      24
<PAGE>
 
  Any gain or loss realized upon a sale of shares of the Fund by a shareholder
who is not a dealer in securities will be treated as a long-term capital gain
or loss if the shares have been held for more than one year and otherwise as a
short-term capital gain or loss. Any such loss with respect to shares that are
held for six months or less however, will be treated as long-term capital loss
to the extent of any capital gain distributions received by the shareholder.
 
  The Fund has obtained opinions of counsel to the effect that neither (i) the
conversion of Class B shares into Class A shares nor (ii) the exchange of any
Class of the Fund's shares for any other Class of its shares constitutes a
taxable event for federal income tax purposes. However, such opinions are not
binding on the Internal Revenue Service.
 
  Net tax-exempt interest distributed by the Fund to shareholders may not be
exempt from state or local taxation. Shareholders are advised to consult their
own tax advisers regarding specific questions as to federal, state or local
taxes. See "Taxes, Dividends and Distributions" in the Statement of Additional
Information.
 
WITHHOLDING TAXES
 
  Under the Internal Revenue Code, the Fund is generally required to withhold
and remit to the U.S. Treasury 31% of taxable dividends, capital gain
distributions and redemption proceeds payable to individuals and certain
noncorporate shareholders who fail to furnish correct tax identification
numbers on IRS Form W-9 (or IRS Form W-8 in the case of certain foreign
shareholders). Withholding at this rate is also required from dividends and
capital gain distributions (but not redemption proceeds) payable to
shareholders who are otherwise subject to backup withholding. Dividends from
taxable net investment income and net short-term capital gains paid to a
foreign shareholder will generally be subject to U.S. withholding tax at the
rate of 30% (or lower treaty rate).
 
DIVIDENDS AND DISTRIBUTIONS
 
  THE FUND EXPECTS TO DECLARE DAILY AND PAY MONTHLY DIVIDENDS OF NET
INVESTMENT INCOME AND MAKE DISTRIBUTIONS OF NET CAPITAL GAINS, IF ANY, AT
LEAST ANNUALLY. Dividends paid by the Fund with respect to each class of
shares, to the extent any dividends are paid, will be calculated in the same
manner, at the same time, on the same day and will be in the same amount
except that each class will bear its own distribution expenses, generally
resulting in lower dividends for Class B and Class C shares in relation to
Class A shares. Distributions of net capital gains, if any, will be paid in
the same amount for each class of shares. See "How the Fund Values its
Shares."
 
  DIVIDENDS AND DISTRIBUTIONS WILL BE PAID IN ADDITIONAL FUND SHARES BASED ON
THE NET ASSET VALUE OF EACH CLASS OF FUND SHARES ON THE PAYMENT DATE OR SUCH
OTHER DATE AS THE BOARD OF DIRECTORS MAY DETERMINE, UNLESS THE SHAREHOLDER
ELECTS IN WRITING NOT LESS THAN FIVE BUSINESS DAYS PRIOR TO THE RECORD DATE TO
RECEIVE SUCH DIVIDENDS AND DISTRIBUTIONS IN CASH. Such election should be
submitted to Prudential Mutual Fund Services LLC, Attention: Account
Maintenance, P.O. Box 15015, New Brunswick, New Jersey 08906-5015. The Fund
will notify each shareholder after the close of the Fund's taxable year both
of the dollar amount and the taxable status of that year's dividends and
distributions on a per share basis. If you hold shares through Prudential
Securities, you should contact your financial adviser to elect to receive
dividends and distributions in cash.
 
  In determining the amount of capital gains to be distributed, any capital
loss carryovers from prior years will be offset against capital gains. The
Fund intends to invest its assets so that dividends paid from net tax-exempt
interest earned from Municipal Bonds and Notes will qualify as exempt-interest
dividends and be excluded from the shareholder's gross income under the
Internal Revenue Code.
 
                                      25
<PAGE>
 
  Any distributions of net capital gains paid shortly after a purchase by an
investor will have the effect of reducing the per share net asset value of the
investor's shares by the per share amount of the distributions. Such
distributions, although in effect a return of invested principal, are subject
to federal income taxes. Accordingly, prior to purchasing shares of the Fund,
an investor should carefully consider the impact of capital gains
distributions which are expected to be or have been announced.
 
  As of December 31, 1996 the Fund had a capital loss carryforward for federal
income tax purposes of approximately $3,010,300. Accordingly, no capital gains
distribution is expected to be paid to shareholders until net gains have been
realized in excess of such carryforward amount.
 
 
                              GENERAL INFORMATION
 
 
DESCRIPTION OF COMMON STOCK
 
  THE FUND WAS INCORPORATED IN MARYLAND ON JANUARY 9, 1980. THE FUND IS
AUTHORIZED TO ISSUE 750 MILLION SHARES OF COMMON STOCK, $.01 PAR VALUE PER
SHARE, DIVIDED INTO THREE CLASSES, DESIGNATED CLASS A, CLASS B AND CLASS C
COMMON STOCK, EACH OF WHICH CONSISTS OF 250 MILLION AUTHORIZED SHARES. Each
class of common stock represents an interest in the same assets of the Fund
and is identical in all respects except that (i) each class is subject to
different sales charges and distribution and/or service fees, (ii) 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 (except that the Fund has agreed with the SEC in
connection with the offering of a conversion feature on Class B shares to
submit any amendment of the Class A Plan to both Class A and Class B
shareholders), (iii) each class has a different exchange privilege and (iv)
only Class B shares have a conversion feature. See "How the Fund is Managed--
Distributor." The Fund has received an order from the Securities and Exchange
Commission (SEC) permitting the issuance and sale of multiple classes of
common stock. Currently, the Fund is offering only three classes designated
Class A, Class B, and Class C shares. In accordance with the Fund's Articles
of Incorporation, the Board of Directors may authorize the creation of
additional series of common stock and classes within such series, with such
preferences, privileges, limitations and voting and dividend rights as the
Board may determine.
 
  The Board of Directors may increase or decrease the number of authorized
shares without approval by the shareholders. 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 as described under "Shareholder Guide--How to Sell Your
Shares." Each share of each class of common stock is equal as to earnings,
assets and voting privileges, except as noted above, and each class of shares
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 common stock 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. The Fund's shares do not have
cumulative voting rights for the election of Directors, 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 Directors.
 
  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
 
                                      26
<PAGE>
 
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 A 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.

  In making a subsequent purchase order by wire, you should wire State Street
directly and should be sure that the wire specifies Prudential National
Municipals Fund, Inc., Class A, Class B, or Class C shares and your name and
individual account number. It is not necessary to call PMFS to make subsequent
purchase orders utilizing Federal Funds. The minimum amount which may be
invested by wire is $1,000.

</TABLE>
 
  The three classes of shares represent an interest in the same portfolio of
investments of the Fund and have the same rights, except that (i) each class
is subject to different sales charges and distribution and/or service fees,
which may affect performance, (ii) each class has exclusive voting rights on
any matter submitted to shareholders that relates solely to its arrangements
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
(except as noted under the heading "General Information--Description of Common
Stock"), (iii) each class has a different exchange feature and (iv) only Class
B shares have a conversion feature. See "How to Exchange Your Shares" below.
The income attributable to each class and the dividends payable on the shares
of each class will be reduced by the amount of the distribution fee (if any)
of each class. Class B and Class C shares bear the expenses of a higher
distribution fee which will generally cause them to have higher expense ratios
and to pay lower dividends than Class A shares.
 
  Financial advisers and other sales agents who sell shares of the Fund will
receive different compensation for selling Class A, Class B and Class C shares
and will generally receive more compensation initially for selling Class A and
Class B shares than for selling Class C shares.

  IN SELECTING A PURCHASE ALTERNATIVE, YOU SHOULD CONSIDER, AMONG OTHER
THINGS, (1) the length of time you expect to hold your investment, (2) the
amount of any applicable sales charge (whether imposed at the time of purchase
or redemption) and distribution-related fees, as noted above, (3) whether you
qualify for any reduction or waiver of any applicable sales charge, (4) the
various exchange privileges among the different classes of shares (see "How to
Exchange Your Shares" below) and (5) the fact that Class B shares
automatically convert to Class A shares approximately seven years after
purchase (see "Conversion Feature--Class B Shares" below).
 
  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 5 years and
do not qualify for a reduced sales charge on Class A shares, since Class A
shares are subject to a maximum initial sales charge of 3% 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 more than 5 years and do not
qualify for a reduced sales charge on Class A shares, since Class B shares
convert to Class A shares approximately 7 years after purchase and because all
of your money would be invested initially in the case of Class B shares, you
should consider purchasing Class B shares over either Class A or 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 and Class C 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 C shares, you would have to hold your investment for more than
4 years for the higher cumulative annual distribution-related fee on Class C
shares to exceed the initial sales charge plus 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 C distribution-
related fee on the investment, fluctuations in net asset value, the effect of
the return on the investment over this period of time or redemptions during
which the CDSC is applicable.
 
  ALL PURCHASES OF $1 MILLION OR MORE, EITHER AS PART OF A SINGLE INVESTMENT
OR UNDER RIGHTS OF ACCUMULATION OR LETTERS OF INTENT, MUST BE FOR CLASS A
SHARES. SEE "REDUCTION AND WAIVER OF INITIAL SALES CHARGES" BELOW.
 
  CLASS A SHARES
 
  The offering price of Class A shares for investors choosing the initial
sales charge alternative is the next determined NAV plus a sales charge
(expressed as a percentage of the offering price and of the amount invested)
as shown in the following table:

  The Distributor may reallow the entire initial sales charge to dealers.
Selling dealers may be deemed to be underwriters, as that term is defined in
the Securities Act.
 
  In connection with the sale of Class A shares of NAV (without payment of an
initial sales charge), the Manager, the Distributor or one of their affiliates
will pay dealers, financial advisors and other persons which distribute shares
a finders' fee based on a percentage of the net asset value of shares sold by
such person.
 
  REDUCTION AND WAIVER OF INITIAL SALES CHARGES. Reduced sales charges are
available through Rights of Accumulation and Letters of Intent. Shares of the
Fund and shares of other Prudential Mutual Funds (excluding money market funds
other than those acquired pursuant to the exchange privilege) may be
aggregated to determine the applicable reduction. See "Purchase and Redemption
of Fund Shares--Reduction and Waiver of Initial Sales Charges--Class A Shares"
in the Statement of Additional Information.
 
  Other Waivers. Class A shares may be purchased at NAV, through Prudential
Securities or the Transfer Agent, by the following persons: (a) officers and
current and former Directors/Trustees of the Prudential Mutual Funds
(including the Fund), (b) employees of Prudential Securities and PMF and their
subsidiaries and members of the families of such persons who maintain an
"employee related" account at Prudential Securities or the Transfer Agent, (c)
employees of subadvisers of the Prudential Mutual Funds provided that
purchases at NAV are permitted by such person's employer, (d) 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, (e) registered representatives and employees of dealers who have
entered into a selected dealer agreement with Prudential Securities provided
that purchases at NAV are permitted by such person's employer and (f)
investors who have a business relationship with a financial adviser who joined
Prudential Securities from another investment firm, provided that (i) 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, (ii) 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 (iii) the financial adviser served as
the client's broker on the previous purchases.
 
  You must notify the Transfer Agent either directly or through Prudential
Securities or Prusec that you are entitled to the reduction or waiver of the
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
purchased upon the reinvestment of dividends and distributions. See "Purchase
and Redemption of Fund Shares--Reduction and Waiver of Initial Sales Charges--
Class A Shares" in the Statement of Additional Information.
 
  CLASS B AND CLASS C SHARES
 
  The offering price of Class B and Class C shares for investors choosing one
of the deferred sales charge alternatives is the NAV next determined following
receipt of an order by the Transfer Agent or Prudential Securities. Although
there is no sales charge imposed at the time of purchase, redemptions of Class
B and Class C shares may be subject to a CDSC. See "How to Sell Your Shares--
Contingent Deferred Sales Charges." The Distributor will pay sales commissions
of up to 4% of the purchase price of Class B shares to dealers, financial
advisors and other persons who sell the Class B shares at the time of sale
from its own resources. 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
sale commissions from the combination of the CDSC and the distribution fee.
See "How the Fund is Managed--Distributor." In connection with the sale of
Class C shares, the Distributor will pay dealers, financial advisers and other
persons which distribute Class C shares a sales commission of up to 1% of the
purchase price at the time of the sale.

HOW TO SELL YOUR 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 BY THE TRANSFER AGENT
OR PRUDENTIAL SECURITIES. SEE "HOW THE FUND VALUES ITS SHARES." In certain
cases, however, redemption proceeds from the Class B shares will be reduced by
the amount of any applicable contingent deferred sales charge, as described
below. See "Contingent Deferred Sales Charges" below.
 
  IF YOU HOLD SHARES OF THE FUND THROUGH PRUDENTIAL SECURITIES, YOU MUST
REDEEM YOUR SHARES BY CONTACTING 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 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.
 
  If the proceeds of the redemption (a) exceed $50,000, (b) are to be paid to
a person other than the record owner, (c) are to be sent to an address other
than the address on the Transfer Agent's records, or (d) 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.
 
  PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE MADE BY CHECK WITHIN
SEVEN DAYS AFTER RECEIPT BY THE TRANSFER AGENT OF THE CERTIFICATE AND/OR
WRITTEN REQUEST EXCEPT AS INDICATED BELOW. IF YOU HOLD SHARES THROUGH
PRUDENTIAL SECURITIES, PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE
CREDITED TO YOUR PRUDENTIAL SECURITIES ACCOUNT, UNLESS YOU INDICATE OTHERWISE.
Such payment may be postponed or the right of redemption suspended at times
(a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on such Exchange is restricted, (c)
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
(d) during any other period when the SEC, by order, so permits; provided that
applicable rules and regulations of the SEC shall govern as to whether the
conditions prescribed in (b), (c) or (d) exist.
 
  PAYMENT FOR REDEMPTION OF RECENTLY PURCHASED SHARES WILL BE DELAYED UNTIL
THE FUND OR ITS TRANSFER AGENT HAS BEEN ADVISED THAT THE PURCHASE CHECK HAS
BEEN HONORED, UP TO 10 CALENDAR DAYS FROM THE TIME OF RECEIPT OF THE PURCHASE
CHECK BY THE TRANSFER AGENT. SUCH DELAY MAY BE AVOIDED BY PURCHASING SHARES BY
WIRE OR BY CERTIFIED OR OFFICIAL BANK CHECK.
 
  REDEMPTION IN KIND. If the Board of Directors determines 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 SEC. Securities will be readily marketable and will be
valued in the same manner as in regular redemption. See "How the Fund Values
its Shares." If your shares
 
                                      31
<PAGE>
 
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 net asset
value of the Fund during any 90-day period for any one shareholder.
 
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Board
of 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 contingent deferred
sales charges will be imposed on any 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 net asset
value 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 Fund's Transfer Agent, either directly or through Prudential Securities,
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 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. For
more information see "Taxes, Dividends and Distributions" in the Statement of
Additional Information.
 
  CONTINGENT DEFERRED SALES CHARGES
 
  Redemptions of Class B shares will be subject to a contingent deferred sales
charge (CDSC) declining from 5% to zero over a six-year period. Class C shares
redeemed within one year of purchase 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 one year, in the case of Class C
shares. 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. See "How the Fund is Managed--Distributor" and "Waiver of
the Contingent Deferred Sales Charges--Class B Shares" below.
 
  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.
 
                                      32

See "How to Exchange Your Shares" below. The following table sets forth the
rates of the CDSC applicable to redemptions of Class B shares:

        Seventh......................................           None
</TABLE>
 
  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 net asset value above the total amount of
payments for the purchase of Fund shares made during the preceding six years
(five years for shares purchased prior to January 22, 1990); then of amounts
representing the cost of shares held beyond the applicable CDSC period; then
of amounts representing the cost of shares acquired prior to July 1, 1985; 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
net asset value 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.
 
  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 THE 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, 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. In
addition, the CDSC will be waived on redemptions of shares held by a Director
of the Fund.
 
  You must notify the Fund's Transfer Agent either directly or through
Prudential Securities or Prusec, at the time of redemption, that you are
entitled to waiver of the contingent deferred sales charge and provide the
Transfer Agent with such supporting documentation as it may deem appropriate.
The waiver will be granted subject to confirmation of your entitlement. See
"Purchase and Redemption of Fund Shares--Waiver of the Contingent Deferred
Sales Charge--Class B Shares" in the Statement of Additional Information.
 
  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
 
                                      33
<PAGE>
 
be redeemed without charge. The Transfer Agent will calculate the total amount
available for this waiver annually, on the earlier of March 1, 1997 or the
anniversary date of your purchase. The CDSC will be waived (or reduced) on
redemptions until this threshold 12% amount is reached.
 
  A quantity discount may apply to redemptions of Class B shares purchased
prior to August 1, 1994. See "Purchase and Redemption of Fund Shares--Quantity
Discount--Class B Shares Purchased Prior to August 1, 1994," in the Statement
of Additional Information.
 
CONVERSION FEATURE--CLASS B SHARES
 
  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. The first conversion of Class B shares occurred in February 1995, when
the conversion feature was first implemented.
 
  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 net asset value 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. See "How the Fund Values its
Shares."
 
  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 will 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 (i) 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 (ii) that the conversion of shares does not 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.
 
HOW TO EXCHANGE YOUR SHARES
 
  AS A SHAREHOLDER OF THE FUND, YOU HAVE AN EXCHANGE PRIVILEGE WITH CERTAIN
OTHER PRUDENTIAL MUTUAL FUNDS, INCLUDING ONE OR MORE SPECIFIED MONEY MARKET
FUNDS, SUBJECT TO THE MINIMUM INVESTMENT REQUIREMENTS OF SUCH FUNDS. CLASS A,
CLASS B AND CLASS C SHARES MAY BE EXCHANGED FOR CLASS A, CLASS B, AND CLASS C
SHARES, RESPECTIVELY, OF ANOTHER FUND ON THE BASIS OF THE RELATIVE NAV. No
sales charge will be imposed at the time of the exchange. Any applicable CDSC
payable upon the redemption of shares exchanged 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. Class B and Class C shares may not be
exchanged into money market funds other than Prudential Special Money Market
Fund. For purposes of calculating the 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. See "Conversion Feature--Class B Shares"
above. An exchange will be treated as a redemption and purchase for tax
purposes. See "Shareholder Investment Account--Exchange Privilege" in the
Statement of Additional Information.
 
  IN ORDER TO EXCHANGE SHARES BY TELEPHONE, YOU MUST AUTHORIZE TELEPHONE
EXCHANGES ON 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. (The Fund or its agents
could be subject to liability if they fail to employ reasonable 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. The Exchange
Privilege is available only in states where the exchange may legally be made.
 
  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. SEE
"HOW TO SELL YOUR SHARES" ABOVE.
 
  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.
 
  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.
 
  SPECIAL EXCHANGE PRIVILEGES. A special exchange privilege is available for
shareholders who qualify to purchase Class A shares at NAV. See "Alternative
Purchase Plan--Class A Shares--Reduction and Waiver of Initial Sales
Charges". 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
 
                                      35
<PAGE>
 
Class A shares for shareholders who qualify to purchase Class A shares at NAV
on a quarterly basis, unless the shareholder elects otherwise. 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 net asset
value 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 or Prusec that
they are eligible for this special exchange privilege.
 
  The Fund reserves the right to reject any exchange order including exchanges
(and market timing transactions) which are of a size and/or frequency engaged
in by one or more accounts acting in concert or otherwise, that have or may
have an adverse effect on the ability of the Subadviser to manage the
portfolio. The determination that such exchanges or activity may have an
adverse effect and the determination to reject any exchange order shall be in
the discretion of the Manager and the Subadviser.
 
  The Exchange Privilege is not a right and may be suspended, modified or
terminated on 60 days' notice to shareholders.
 
SHAREHOLDER SERVICES
 
  In addition to the exchange privilege, as a shareholder in the Fund, you can
take advantage of the following additional services and privileges:
 
  . AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS WITHOUT A SALES
CHARGE. For your convenience, all dividends and distributions are
automatically reinvested in full and fractional shares of the Fund at NAV
without a sales charge. You 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. If you
hold shares through Prudential Securities, you should contact your financial
adviser.
 
  . AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP). Under ASAP you may make
regular purchases of the Fund's shares in amounts as little as $50 via an
automatic debit to a bank account or Prudential Securities account (including
a Command Account). For additional information about this service, you may
contact your Prudential Securities financial adviser, Prusec representative or
the Transfer Agent directly.
 
  . SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available to
shareholders which provides for monthly or quarterly checks. Withdrawals of
Class B and Class C shares may be subject to a CDSC. See "How to Sell Your
Shares--Contingent Deferred Sales Charges."
 
  . REPORTS TO SHAREHOLDERS. The Fund will send you annual and semi-annual
reports. The financial statements appearing in annual reports are audited by
independent accountants. In order to reduce duplicate mailing and printing
expenses, the Fund will provide one annual and semi-annual shareholder report
and annual prospectus per household. You may request additional copies of such
reports by calling (800) 225-1852 or by writing to the Fund at Gateway Center
Three, Newark, New Jersey 07102-4077. In addition, monthly unaudited financial
data are available upon request from the Fund.
 
  . SHAREHOLDER INQUIRIES. Inquiries should be addressed to the Fund at
Gateway Center Three, Newark, New Jersey 07102-4077, or by telephone at (800)
225-1852 (toll-free) or, from outside the U.S.A., at (908) 417-7555 (collect).
 
  For additional information regarding the services and privileges described
above, see "Shareholder Investment Account" in the Statement of Additional
Information.
