PRUDENTIAL MUNICIPAL SERIES FUND/MARYLAND AND MICHIGAN SERIES
PRUDENTIAL MUNICIPAL BOND FUND/INTERMEDIATE SERIES
 
   
November 25, 1998
    
 
Dear Shareholder:
 
You may be aware that the Trustees of Prudential Municipal Series Fund/Maryland
Series and Michigan Series and the Trustees of Prudential Municipal Bond
Fund/Intermediate Series have recently approved a proposal to exchange the
assets and liabilities of your Series for shares of Prudential National
Municipals Fund. The enclosed proxy materials describe this proposal in detail.
If the proposal is approved by the shareholders and implemented, you will
automatically receive shares of Prudential National Municipals Fund in exchange
for your share of each Series.
 
THE TRUSTEES AND I STRONGLY RECOMMEND THAT YOU VOTE FOR THE PROPOSAL. WE BELIEVE
THAT THIS TRANSACTION SERVES YOUR INTERESTS IN THE FOLLOWING WAYS:
 
SIMILAR STRATEGIES--GREATER FLEXIBILITY
 
     The Funds' investment objectives and strategies, while not identical, are
     similar. Each invests primarily in investment grade, tax-exempt municipal
     bonds. While Maryland and Michigan Series seek to provide income exempt
     from federal and Maryland and Michigan state income taxes, respectively,
     Prudential National Municipals Fund seeks income exempt from only federal
     income taxes. Increasingly, single state series have had difficulty finding
     attractive issues due to a shrinking municipal bond supply--making
     portfolio diversification a challenge. In contrast, Prudential National
     Municipals Fund is nationally diversified, enabling it to invest in a wider
     range of municipal bond investment opportunities.
 
EXPENSE LEVELS
 
     The Series have relatively few assets and have not been able to attract new
     assets. They operated with relatively high expense ratios before voluntary
     management fee waivers, which were discontinued by the Manager as of
     September 1, 1997.
 
POTENTIAL FOR HIGHER INCOME GENERALLY EXEMPT INCOME TAXES
 
     The municipal obligations held by National Municipals Fund have
     historically had a higher gross yield than the obligations in the Series'
     portfolios and National Municipals Fund has lower expense ratios than the
     Series due to its appreciably larger size.
 
   
PRUDENTIAL NATIONAL MUNICIPALS FUND'S investment objective is to seek a high
level of current income exempt from federal income taxes. The Fund seeks to
achieve this objective by investing in a broadly diversified portfolio of
municipal bonds issued from across the country. Portfolio manager Peter
Allegrini has over 19 years of investment experience.

for their approval. The Shareholders of each Series vote separately on the
respective Plan, and the reorganization of any series (each a Reorganization)
into National Municipals Fund is not contingent on that Plan being approved by
any other Series.
 
THE PROPOSED REORGANIZATIONS
 
    The Directors of National Municipals Fund and the Trustees of both Series
Fund and Municipal Bond Fund have approved each respective Plan. Each Plan
provides for the transfer of all the assets of the respective Series in exchange
for shares of common stock of National Municipals Fund and the assumption
 
                                       2

by National Municipals Fund of the liabilities, if any, of such Series.
Following approval by the shareholders of the Maryland or Michigan Series, Class
A shares of National Municipals Fund will be distributed to Class A, Class B and
Class C shareholders of that Series and the Series will be terminated. Following
approval by Intermediate Series' shareholders, Class A, Class B, Class C and
Class Z shares of National Municipals Fund will be distributed to Class A, Class
B, Class C and Class Z shareholders, respectively, of Intermediate Series, and
Intermediate Series will be terminated. Each Reorganization will become
effective as soon as practicable after the Meeting. Each Series' shareholders
will receive the number of full and fractional shares of National Municipals
Fund of the applicable Class equal in value (rounded to the third decimal place)
to such shareholder's corresponding shares of the Series as of the closing date.
    
 
REASONS FOR THE REORGANIZATIONS
 
    There are a number of similarities between each Series and National
Municipals Fund that led to consideration of the Plans. The following are among
the reasons for each Reorganization proposed by Prudential Investments Fund
Management LLC (PIFM), the Manager of each Fund:
 
   
    THE SERIES HAVE BEEN UNABLE TO ATTRACT SIGNIFICANT ASSETS.  Assets in each
of the Series have been steadily declining during the past several years. As of
June 30, 1998, Maryland and Michigan Series' assets were approximately
$30,950,000 and $54,413,000, respectively, with 1,357 and 2,368 shareholders,
respectively. As of June 30, 1998, the Intermediate Series assets were
approximately $38,624,000, with 1,711 shareholders. As a result, the Series have
been operated with relatively high expense ratios. Because of their size, the
Series' do not enjoy the economies of scale of National Municipals Fund. The
Manager believes the Series' situations are not likely to improve. The
Distributor of Series Fund and Municipal Bond Fund limited distribution fees
with respect to the Class A and Class C shares of the Series to no more than .10
of 1% of the average daily net asset value of the Class A shares and to no more
than .75 of 1% of the average daily net assets of the Class C shares,
respectively, for each respective Series. Although such distribution fee
limitations or waivers have been in place for some time for the Series, such
limitations or waivers are voluntary and could therefore be eliminated at any
time.
    
 
    NATIONAL MUNICIPALS FUND AND THE SERIES HAVE SIMILAR INVESTMENT
POLICIES.  National Municipals Fund and each Series invest primarily in
investment grade debt securities of municipal debt obligations, the investment
income from which is exempt from federal income taxes. However, shareholders of
the Maryland and Michigan Series should recognize that if the Reorganization
occurs, income from their investment in National Municipals Fund will likely be
subject to Maryland and Michigan state income taxes, as applicable. Shareholders
of each Series are advised to consult their own tax advisers regarding specific
questions as to federal, state, or local taxes. See "--Investment Objectives and
Policies" below. An additional difference is that each of the Series seeks a
high level of income consistent with capital preservation while National
Municipals Fund does not similarly seek capital preservation.
 
    NATIONAL MUNICIPALS FUND OFFERS GREATER DIVERSIFICATION OF ASSETS AND
REDUCES POTENTIAL CONCERNS RELATING TO INADEQUATE SUPPLY OF MUNICIPAL BONDS FROM
SPECIFIC STATES.  Because the Maryland and Michigan Series must each invest at
least 80% of its total assets in municipal obligations of issuers located in
Maryland or Michigan, respectively, and other obligations of qualifying issuers,
each of their portfolios are more susceptible to factors adversely affecting
issuers of such obligations than is a national municipal bond fund such as
National Municipals Fund. In addition, the State Series from time to time may
have difficulty obtaining suitable investments due to inadequate supply. A
national municipal fund such as National Municipals Fund is not similarly
constrained as to potential purchasers.
 
                                       3
<PAGE>
    AFTER IMPLEMENTATION OF EACH PLAN, THE FORMER SHAREHOLDERS OF EACH SERIES
AND THE SHAREHOLDERS OF NATIONAL MUNICIPALS FUND MAY BENEFIT FROM REDUCED
EXPENSES RESULTING FROM GREATER ECONOMIES OF SCALE.  The Trustees of Series
Fund, the Trustees of the Municipal Bond Fund and the Directors of National
Municipals Fund believe that each Reorganization may achieve certain economies
of scale that each Series alone cannot realize because of its small size, and
that National Municipals Fund would realize the benefits of a larger asset base.
The combination of the Series and National Municipals Fund would eliminate
certain duplicate expenses, such as those incurred in connection with separate
audits and the preparation of separate financial statements for the Series and
National Municipals Fund, and reduce other expenses, because their expenses
would be spread across a larger asset base.
 
   
    The ratios of total expenses to average net assets for Class A, Class B,
Class C and Class Z shares of National Municipals Fund and Intermediate Series
and Class A, Class B, and Class C shares of each State Series were as follows:

    specified.
    
 
   
     AFTER IMPLEMENTATION OF THE PLANS, CERTAIN SHAREHOLDERS OF THE STATE SERIES
SHOULD BENEFIT FROM REDUCED DISTRIBUTION FEES AND SALES LOADS.  If the State
Series Plan is implemented, each Class A, Class B and Class C shareholder of the
State Series will receive the number of full and fractional Class A shares of
National Municipals Fund equal to the net asset value (rounded to the third
decimal place) of such shareholder's shares as of the closing date. Class A,
Class B and Class C shares of the State Series currently are subject to maximum
distribution fees of .10 of 1%, .50 of 1% and .75 of 1%, respectively (after
reduction). Class A shares of National Municipals Fund currently are subject to
a maximum distribution fee of .10 of 1% (after reduction). Accordingly, Class B
and Class C shareholders of the State Series should benefit from reduced
distribution fees since they will receive Class A shares in the Reorganization.
Furthermore, Class B shares of the State Series currently are subject to maximum
deferred sales loads of up to 5% and Class C shares of the State Series
currently are subject to an initial sales load of 1% and deferred sales load of
1%. If the State
    
 
                                       4
<PAGE>
Series Plan is implemented, such shareholders will receive Class A shares of
National Municipals Fund, which are not subject to a deferred sales load.
Therefore, Class B and Class C shareholders of the State Series should benefit
from the elimination of otherwise applicable sales loads if the State Series
Plan is approved.
 
    If the State Series Plan is implemented, Class A shareholders of the State
Series will be subject to the same distribution fee charged by National
Municipals Fund as is currently charged by the State Series (each after
reduction). Like Class A shares of the State Series, the Class A shares of
National Municipals Fund to be received in the Reorganizations by Class A
shareholders of the State Series will not be subject to any deferred sales load.
Therefore, Class A shareholders of the State Series will not be subject to any
additional distribution fees or sales loads following the Reorganizations.
 
   
    If the Intermediate Series Plan is implemented, each Class A, Class B, Class
C and Class Z shareholder of Intermediate Series will receive the number of full
and fractional Class A, Class B, Class C and Class Z shares of National
Municipals Fund equal to the net asset value (rounded to the third decimal
place) of such shareholder's shares as of the closing date. Class A, Class B and
Class C shares of Intermediate Series currently are subject to maximum
distribution fees (after reduction) of .10 of 1%, .50 of 1% and .75 of 1%,
respectively, which are the same maximum distribution fees (after reduction)
with respect to Class A, Class B and Class C shares of National Municipals Fund.
Class A shares of Intermediate Series and National Municipals Fund are not
subject to any deferred sales load and Class B and Class C shares of
Intermediate Series are subject to the same sales loads with respect to Class B
and Class C shares of National Municipals Fund, respectively. Furthermore, Class
Z shares of Intermediate Series and National Municipals Fund are not subject to
any distribution fees or sales loads. Therefore, Class A, Class B, Class C and
Class Z shareholders of Intermediate Series will not be subject to any
additional distribution fees or sales loads following the Reorganization.
    
 
   
    NATIONAL MUNICIPALS FUNDS HAS ACHIEVED A YIELD COMPARABLE TO THE
SERIES.  The municipal obligations held by National Municipals Fund have
historically had a higher gross yield than the obligations in the other Series'
portfolios, and National Municipals Fund has lower expense ratios than each
Series due to its appreciably larger size. The following table presents the
thirty day yield for each Series and National Municipals Fund (on a pre- and
after-state income tax basis) for the period ended June 30, 1998:

    For the reasons set forth below under "The Proposed Transaction--Reasons for
the Reorganizations Considered by the Trustees/Directors," the Directors of
National Municipals Fund, and the Trustees of Series Fund and Municipal Bond
Fund, including those Directors or Trustees who are not "interested persons"
(Independent Directors or Trustees), as that term is defined in the Investment
Company Act of 1940, as amended (Investment Company Act), have concluded that
each Reorganization would be in the best interests of the shareholders of
National Municipals Fund and the respective Series and that the interests of
shareholders of National Municipals Fund and the respective Series will not be
diluted as a result of the proposed transaction. Accordingly, the Board of
Directors of National Municipals Fund and the Trustees of Series Fund and
Municipal Bond Fund each recommend approval of the respective Plans.
 
STRUCTURE OF THE SERIES AND NATIONAL MUNICIPALS FUND
 
   
    Each Series is authorized to issue an unlimited number of shares of
beneficial interest, $.01 par value per share, whereas National Municipals Fund
is authorized to issue one billion shares of common stock, $.01 par value per
share. The State Series have each divided their shares into three classes,
designated Class A, Class B and Class C, each of which is currently being
offered by the respective funds. National Municipals Fund and Intermediate
Series have each divided their shares into four classes, designated Class A,
Class B, Class C and Class Z, each of which is currently being offered. Each
class of shares represents an interest in the same assets of the Maryland,
Michigan or Intermediate Series or National Municipals Fund, as the case may be,
and is identical in all respects except that (i) each class is subject to
different sales charges and/or service fees (except for Class Z shares of
National Municipals Fund and Intermediate Series, which are not subject to any
sales charges or 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, (iii) each class has a different exchange privilege, (iv) only
Class B shares have a conversion feature and (v) with respect to National
Municipals Fund and Intermediate Series, Class Z shares are offered to a limited
group of investors. The distribution systems for Class A, Class B and Class C
shares of each Fund are identical. Share certificates will be issued by National
Municipals Fund upon written request to Prudential Mutual Fund Services LLC, the
Fund's Transfer Agent. See "Shareholder Guide" in the National Municipals Fund's
Prospectus. National Municipals Fund has adopted a plan pursuant to Rule 18f-3
under the Investment Company Act permitting the issuance and sale of multiple
classes of shares. Pursuant to National Municipals Fund's Articles of
Incorporation, Series Fund's Declaration of Trust and Municipal Bond Fund's
Declaration of Trust, each Fund's Board of Directors/Trustees may authorize the
creation of additional series of shares, and classes within such series, with
such preferences, privileges, limitations and voting and dividend rights as that
Fund's Board of Directors/Trustees may determine.
    
 
   
    The Board of Directors/Trustees of each Fund may increase or decrease the
number of authorized shares of its respective Fund without approval by the
shareholders. Shares of National Municipals Fund or a Series, when issued, are
fully paid, nonassessable, fully transferable and redeemable at the option of
the holder. Shares are also redeemable at the option of each Fund under certain
circumstances. 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 National Municipals Fund or a Series is
entitled to its portion of all of National Municipals Fund's or the Series,
assets after all debt and expenses of that Fund have been paid. Since Class A,
Class B and Class C shares bear distribution expenses, the liquidation proceeds
to shareholders of those classes are likely to be lower than to shareholders of
Class Z shares, which are not subject to any distribution fees. None of the
Funds' shares have cumulative voting rights for the election of
Directors/Trustees.
    
 
                                       7
<PAGE>
    If a stock certificate is desired by a shareholder of National Municipals
Fund or a Series, it must be requested in writing for each purchase of shares.
Certificates are issued only for full shares. Shareholders who hold their shares
through Prudential Securities Incorporated (Prudential Securities) will not
receive stock certificates.
 
    It is the present intent of the Directors of National Municipals Fund and
the Trustees of Series Fund and Municipal Bond Fund not to hold annual meetings
of shareholders unless the election of Directors/Trustees is required under the
Investment Company Act, nor to hold special meetings of shareholders unless
required by the Investment Company Act or state law.
 
INVESTMENT OBJECTIVES AND POLICIES
 
    National Municipals Fund's investment objective is to seek a high level of
current income exempt from federal income taxes. There can be no assurance that
such investment objective will be achieved. National Municipals Fund seeks to
achieve its objective by investing primarily in long-term medium quality bonds
of municipalities possessing adequate but not outstanding capacities to service
their debt. While the investment adviser will not be limited by the ratings
assigned by the rating services, National Municipals Fund will be principally
invested in municipal bonds rated A and Baa by Moody's Investors Group (Moody's)
and A and BBB by Standard & Poor's Ratings Group (S&P). Unlike the Series,
preservation of capital is not an objective for National Municipals Fund. Under
normal circumstances, National Municipals Fund intends to invest substantially
all, and in any event at least 80%, of its total assets in municipal bonds and
municipal notes (E.G., tax revenue and bond anticipation notes). National
Municipals Fund may invest in variable rate securities and inverse floating rate
obligations and may engage in various hedging and return enhancing strategies,
including the purchase and sale of derivatives. These strategies include the
purchase of put options and the purchase and sale of financial futures contracts
and options thereon. See "Principal Risk Factors--Hedging and Return Enhancement
Strategies." National Municipals Fund may invest up to 15% of its net assets in
illiquid securities and may borrow an amount equal to no more than 33 1/3% of
the value of its total assets from banks for temporary, extraordinary or
emergency purposes or for the clearance of transactions.
 
    The investment objective of each of Maryland and Michigan Series is to
provide the maximum amount of income that is exempt from, respectively, Maryland
and Michigan state tax and federal income taxes as is consistent with the
preservation of capital and, in conjunction therewith, the Maryland and Michigan
Series may each invest in debt securities with the potential for capital gain.
There can be no assurance that such investment objectives will be achieved. To
achieve these objectives, the Maryland and Michigan Series each seeks to invest
at least 70% of its total assets in debt obligations rated Baa or above by
Moody's or BBB or above by S&P and may invest up to 30% of its total assets in
debt obligations rated below Baa by Moody's or BBB by S&P. The Maryland and
Michigan Series each invests primarily in municipal and local government
obligations of Maryland and Michigan, respectively, and obligations of other
qualifying issuers, such as issuers located in Puerto Rico, the Virgin Islands
and Guam, which pay income exempt, in the opinion of counsel, from the state
taxes of Michigan and Maryland, respectively, and federal income taxes.
Therefore, Maryland and Michigan Series investors who are residents of Maryland
or Michigan, respectively, receive income that is generally exempt from income
taxation by their state of residence.
 
    Intermediate Series' investment objective is to provide the maximum amount
of income that is eligible for exclusion from federal income taxes consistent
with the preservation of capital. There can be no assurance that the investment
objective will be achieved. Intermediate Series invests all of its assets in
securities rated at least BBB by S&P or Baa by Moody's and invests at least 60%
of its portfolio in securities rated A or better by Moody's or S&P.

    Each Series may invest in floating rate and variable rate securities,
including participation interests therein and inverse floating rate obligations.
Each Series may purchase and sell options and futures contracts, however, the
Maryland and Michigan Series may only do so for hedging purposes. See "Principal
Risk Factors--Hedging and Return Enhancement Strategies" below. Each Series may
invest up to 15% of its net assets in illiquid securities and may borrow an
amount equal to no more than 33 1/3% of the value of its total assets from banks
for temporary, extraordinary or emergency purposes or for the clearance of
transactions.
 
    The State Series will invest in long-term obligations and the
dollar-weighted average maturity of the State Series' portfolio will generally
range from ten to twenty years. The State Series may also invest in certain
short-term tax exempt notes such as Tax Anticipation Notes, Revenue Anticipation
Notes, Bond Anticipation Notes, Construction Loan Notes and variable and
floating rate demand notes. Intermediate Series invests in municipal obligations
with maturities of between 5 and 15 years and simultaneously hedges the price
volatility of such contracts through the sale of futures contracts. Rather than
hedging the municipal obligation entirely, Intermediate Series will sell futures
contracts in sufficient amounts so that the dollar-weighted average maturity of
Intermediate Series' portfolio will be more than three and less than ten years.
In this manner, the investment adviser creates a synthetic obligation through
the construction of a partially hedged longer-term obligation position. See
"Principal Risk Factors--Long Term Bonds."

1997.
 
   
    Under subadvisory agreements between PIFM and The Prudential Investment
Corporation, (PIC or the Subadviser), the Subadviser provides investment
advisory services for the management of the respective Funds. Each subadvisory
agreement provides that PIFM will reimburse the Subadviser for its reasonable
costs and expenses in providing investment advisory services. PIFM continues to
have responsibility for all investment advisory services pursuant to the
management agreements for both Funds and supervises the Subadviser's performance
of its services on behalf of each Fund.

    DISTRIBUTION FEES.  Prudential Investment Management Series LLC (the
Distributor), a wholly-owned subsidiary of Prudential and an affiliate of
Prudential Securities and Pruco Securities Corporation, serves as the
distributor of the Class A, Class B and Class C shares of each Fund and for
Class Z shares of National Municipals Fund and Intermediate Series for Municipal
Bond Fund.
    
 
   
    Under separate Distribution and Service Plans adopted by each Fund (the
Class A Plan, Class B Plan and Class C Plan, collectively, the Distribution
Plans) pursuant to Rule 12b-1 under the Investment Company Act, and approved by
the shareholders of the applicable class of National Municipals Fund and each
Series and under separate distribution agreements (the Distribution Agreements),
the Distributor incurs the expenses of distributing the Class A, Class B and
Class C shares of National Municipals Fund and each Series, respectively. The
Distributor incurs the expenses of distributing the Fund's Class Z shares under
Distribution Agreements with National Municipals Fund and Municipal Series Fund,
none of which are reimbursed. These expenses include (i) commissions and account
servicing fees, (ii) advertising expenses, (iii) the cost of printing and
mailing prospectuses, and (iv) indirect and overhead costs associated with the
sale of each of National Municipals Fund's and the Series' shares.
    
 
    Under the Funds' Class A, Class B and Class C Plans, each Fund pays the
Distributor for distribution expenses at an annual rate of up to .30 of 1%, .50
of 1% and up to 1% of the average daily net assets of the Class A, Class B and
Class C shares, respectively. Each Fund's Class B Plan provides for the payment
of an asset-based sales charge of up to .50 of 1% of the average daily net
assets of National Municipals Fund's and each Series' Class B shares and a
service fee of up to .25 of 1% of the average daily net assets of National
Municipals Fund's and each Series' Class B shares; provided that the total
distribution-related fee does not exceed .50 of 1%. National Municipals Fund's
and each Series' Class C Plan provides for the payment to the Distributor of an
asset-based sales charge of up to .75 of 1% of the average daily net assets of
the Class C shares and a service fee of up to .25 of 1% of the average daily net
assets of the Class C shares.
 
    The Distributor has voluntarily limited its distribution-related fees
payable under National Municipals Fund's and each Series', Class A and Class C
Plans to .10 of 1% and .75 of 1% of the average daily net assets, respectively,
of the Class A and Class C shares.
 
    For the most recently completed fiscal year ends, each Fund paid the
Distributor .10%, .50% and .75% of the average daily net assets of the Class A,
Class B and Class C shares, respectively.
 
    Under each Plan, each Fund is obligated to pay distribution and/or service
fees to the Distributor as compensation for distribution and service activities,
not as reimbursement for specific expenses incurred. If the Distributor's
expenses exceed its distribution and service fees, that Fund will not be
obligated to pay any additional expenses. If the Distributor's expenses are less
than such distribution and service fees, it will retain its full fees and
realize a profit. The Class A Plan, Class B Plan and Class C Plan of National
Municipals Fund are substantially identical to the Class A Plan, Class B Plan
and Class C Plan, respectively, of Series Fund (State Series) and Municipal Bond
Fund (Intermediate Series).
 
    OTHER EXPENSES.  National Municipals Fund and each Series also pay certain
other expenses in connection with their operation, including accounting, legal,
audit and registration expenses. Although the basis for calculating these fees
and expenses is the same for National Municipals Fund and each Series, the per
share effect on shareholder returns is affected by their relative size.
Combining the National Municipals Fund with each Series will reduce certain
expenses. For example, only one annual audit of the combined Fund will be
required rather than separate audits of National Municipals Fund and each Series
as is currently required.
 
   
    The following summaries of shareholder transaction expenses and annual
operating expenses are to assist investors in understanding the various costs
and expenses that an investor in each Series will bear directly or indirectly.

that an investor would be subject to in connection with a purchase or redemption
of Class A, Class B and Class C Shares of National Municipals Fund and the
Series and Class Z shares of National Municipals Fund and Intermediate Series.
However, if the Plans are implemented, Class A, Class B and Class C shareholders
of the State Series will receive Class A shares of National Municipals Fund,
regardless of the class of shares of the Series held prior to the
Reorganizations.

 + 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 National Municipals Fund and each Series may not
   exceed 6.25% of total gross sales, subject to certain exclusions. This 6.25%
   limitation is imposed on each class of each Fund/ Series rather than on a per
   shareholder basis. Therefore, long-term shareholders of each Fund/Series may
   pay more in total sales charges than the economic equivalent of 6.25% of such
   shareholders' investment in such shares.

   years after purchase.
 
   
    EXPENSE RATIOS.  For its fiscal year ended December 31, 1997, total expenses
stated as a percentage of average net assets of National Municipals Fund were
0.70%, 1.10% and 1.35% for Class A, Class B and Class C shares. Absent the
management fee waiver, such ratio would have been 0.73%, 1.13% and 1.38% for
Class A, Class B and Class C shares, respectively. For the six-month period
ended June 30, 1998, total expenses (annualized and unaudited), stated as a
percentage of average net assets of National Municipals Fund were 0.73%, 1.13%
and 1.38% for Class A, Class B, and Class C shares, respectively. National
Municipals Fund commenced offering Class Z shares November 23, 1998. Total
expenses (unaudited) stated as a percentage of average net assets with respect
to Class Z shares are estimated to be 0.60% (after waiver) and 0.63% (absent the
management fee waiver) for the fiscal year ended December 31, 1997 based on
expenses to have been incurred if Class Z shares had been in existence during
such fiscal year. Total expenses (annualized and unaudited) stated as a
percentage of average net assets with respect to Class Z shares are estimated to
be 0.63% for the six-month period ended June 30, 1998 based on expenses to have
been incurred if Class Z shares had been in existence during such period. For
the fiscal year ended August 31, 1998, total expenses stated as a percentage of
average net assets of each of the State Series were 1.19%, 1.58% and 1.83% for
Maryland Series and 0.92%, 1.32% and 1.57% for Michigan Series for Class A,
Class B and Class C shares, respectively. For the fiscal year ended April 30,
1998, total expenses stated as a percentage of average net assets of
Intermediate Series were 1.31%, 1.71%, 1.96% and 1.21% for Class A, Class B,
Class C and Class Z shares, respectively. Absent the management fee waiver and
expense subsidy, such ratios would have been 1.33%, 1.73%, 1.98% and 1.23% for
the Class A, Class B, Class C and Class Z shares, respectively.

    ANNUAL FUND OPERATING EXPENSES.  Following the Reorganizations, the actual
expense ratios of the combined fund are expected to be lower than those of the
State Series for the State Series' fiscal year ended August 31, 1998 and than
those of Intermediate Series for Intermediate Series' fiscal year ended April
30, 1998. Set forth below is a comparison of National Municipals Fund's and each
Series' anticipated operating expenses based on, in the case of National
Municipals Fund, the fiscal year ended December 31, 1997, in the case of State
Series, the fiscal year ended August 31, 1998 and, in the case of Intermediate
Series, the fiscal year ended April 30, 1998, each before management fee waiver
and before consideration of expense subsidy. The ratios for National Municipals
Fund, Maryland and Michigan Series, and Intermediate Series are also shown on a
pro forma (estimated) combined basis, after giving effect to the
Reorganizations.

    each Fund may pay a distribution fee of up to .30 of 1% and 1% per annum of

*   National Municipals Fund commenced offering Class Z shares November 23,
    1998.
    
 
PURCHASES AND REDEMPTIONS
 
   
    Purchases of shares of each Series and National Municipals Fund are made
through the Distributor, through dealers, including Prudential Securities, Pruco
Securities Corporation (Prusec) or directly from the respective Fund, through
its transfer agent, Prudential Mutual Fund Services LLC (PMFS or the Transfer
Agent), at the net asset value per share next determined after receipt of a
purchase order by the Transfer Agent or plus a sales charge which may be imposed
either (i) at the time of purchase (Class A shares), (ii) on a deferred basis
(Class B shares) or (iii) both (Class C shares).
    
 
    The minimum initial investment for Class A and Class B shares of each Fund
is $1,000 per class and $5,000 for Class C shares and the minimum subsequent
investment is $100 for all classes. Class A shares of each Fund are sold with an
initial sales charge of up to 3.00% of the offering price. Class B shares of
each
 
                                       13
<PAGE>
   
Fund are sold without an initial sales charge but are subject to a contingent
deferred sales charge (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 of each Fund are sold with an initial sales charge of
1% and, for eighteen months after purchase, are subject to a 1% contingent
deferred sales charge on redemptions. Like Class B shares, Class C shares are
subject to higher ongoing distribution-related expenses than Class A shares but
do not convert to another class. Class Z shares of National Municipals Fund and
Intermediate Series are sold without either an initial sales charge or
contingent deferred sales charge to a limited group of investors. Class Z Shares
are not subject to any ongoing service or distribution expenses.
    
 
   
    Shares of each Fund may be redeemed at any time at the net asset value next
determined after the Distributor or the Transfer Agent receives the sell order.
As indicated above, the proceeds of redemptions of Class B and Class C shares
may be subject to a contingent deferred sales charge. Class A, Class B and Class
C shareholders of the State Series will receive the number of full and
fractional Class A shares of National Municipals Fund equal to the net asset
value (rounded to the third decimal place) to such shareholders' Class A, Class
B, and Class C shares as of the closing date. The Class A, Class B, Class C and
Class Z shareholders of Intermediate Series will receive the number of full and
fractional Class A, Class B, Class C shares and Class Z of National Municipals
Fund equal to the net asset value (rounded to the third decimal place) to such
shareholders' shares as of the closing date. NO CONTINGENT DEFERRED SALES
CHARGES WILL BE IMPOSED IN CONNECTION WITH THE REORGANIZATION. FOLLOWING THE
REORGANIZATION, SHAREHOLDERS HOLDING CLASS A AND CLASS Z SHARES OF NATIONAL
MUNICIPALS FUND LIKEWISE WILL NOT BE SUBJECT TO ANY CONTINGENT DEFERRED SALES
CHARGES.
    
 
EXCHANGE PRIVILEGES
 
   
    The exchange privileges available to Class A, Class B, Class C and Class Z
shareholders of National Municipals Fund are identical to the exchange
privileges of Class A, Class B, Class C and Class Z (Intermediate Series only)
shareholders, respectively, of each Series. Shareholders of both National
Municipals Fund and each Series 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,
Class C and Class Z shares of each Fund may be exchanged for Class A, Class B,
Class C and Class Z shares, respectively, of another fund on the basis of
relative net asset value. No sales charge will be imposed at the time of the
exchange. Any applicable contingent deferred sales charge 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 of either Fund 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. An exchange will be treated as a redemption and purchase for
tax purposes.
    
 
DIVIDENDS AND DISTRIBUTIONS
 
    Each Fund expects to declare daily and to pay dividends of net investment
income, if any, monthly and make distributions at least annually of any net
capital gains. Shareholders of National Municipals Fund and each Series receive
dividends and other distributions in additional shares of National Municipals
Fund and
 
                                       14
<PAGE>
each Series, respectively, unless they elect to receive them in cash. Each
Series shareholder's election with respect to reinvestment of dividends and
distributions in each Series will be automatically applied with respect to the
National Municipals Fund shares he or she receives pursuant to the applicable
Plan.
 
FEDERAL TAX CONSEQUENCES OF PROPOSED REORGANIZATION
 
    The Funds shall have received on the closing date opinions of Swidler Berlin
Shereff Friedman, LLP to the effect that each of the proposed Reorganizations
will constitute a tax-free reorganization within the meaning of Section
368(a)(1)(C) of the Internal Revenue Code of 1986, as amended (the Internal
Revenue Code). Accordingly, no gain or loss will be recognized to National
Municipals Fund or any Series upon the transfer of assets solely in return for
shares of National Municipals Fund and National Municipals Fund's assumption of
liabilities, if any, or to shareholders of any Series upon their receipt of
shares of National Municipals Fund in return for their shares of the Series. The
tax basis for the shares of National Municipals Fund received by each Series'
shareholders will be the same as their tax basis for the shares of each
respective Series to be constructively surrendered in exchange therefor. In
addition, the holding period of the shares of National Municipals Fund to be
received pursuant to each Reorganization will include the period during which
the shares of each respective Series to be constructively surrendered in
exchange therefor were held, provided the latter shares were held as capital
assets by the shareholders on the date of the exchange. See "The Proposed
Transaction--Tax Considerations."
 
                             PRINCIPAL RISK FACTORS
 
    As the investment policies of Natural Municipals Fund and the Series are
similar, the risks associated with such investments also are similar. Below is a
summary of such risks. For a more complete discussion of the risks attendant to
an investment in National Municipals Fund, please see the National Municipals
Fund Prospectus, which accompanies this Prospectus and Proxy Statement.
 
RATINGS
 
    While National Municipals Fund's investment adviser will not be limited by
the ratings assigned by the ratings services, the municipal bonds in which
National Municipals Fund's portfolio will be principally invested will be rated
A or Baa by Moody's and A or BBB by S&P, or, if not rated, will be, in the
judgment of the investment adviser, of substantially comparable quality. Bonds
rated Baa by Moody's lack outstanding investment characteristics and, in fact,
have speculative characteristics as well. In addition, National Municipals Fund
may acquire municipal bonds which have been rated below medium quality (below
BBB/ Baa) by the ratings services if, in the judgment of National Municipals
Fund's investment adviser, the bonds have the characteristics of medium quality
obligations.
 
    Each of Maryland and Michigan Series invests at least 70% of its total
assets in securities which are rated BBB or above by S&P and Baa or above by
Moody's or comparably rated by another NRSRO and up to 30% of its total assets
in securities rated below BBB by S&P or below Baa by Moody's or comparably rated
by another NRSRO or, if unrated, will possess creditworthiness, in the opinion
of the investment adviser, comparable to such investment grade rated securities.
Such lower-rated high yield securities are commonly referred to as junk bonds.
Intermediate Series, under normal circumstances, invests all of its assets in
securities rated at least BBB by S&P or Baa by Moody's and invests at least 60%
of its portfolio in securities rated A or better by Moody's or S&P.
 
    Fixed-income securities are subject to the risk of an issuer's inability to
meet principal and interest payments on the obligations (credit risk) and may
also be subject to price volatility due to such factors as interest rate
sensitivity, market perception of the creditworthiness of the issuer and general
market liquidity
 
                                       15
<PAGE>
   
(market risk). Municipal bonds of medium or lower-rated quality (I.E., high
yield or junk bonds) are subject to fluctuation in value as a result of changing
economic circumstances, as well as changes in interest rates. Thus, while medium
or lower-rated obligations generally provide a higher yield than high quality
municipal bonds of similar maturities, such obligations 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 have
speculative characteristics not present in bonds of higher quality. Lower-rated
or unrated debt obligations also present the risk that, if an issuer calls the
obligation in for redemption, it may have to be replaced with a lower-yielding
security, resulting in a decreased return for investors. If a State Series
experiences unexpected net redemptions, it may be forced to sell its higher
quality securities, resulting in a decline in the overall credit quality of the
Series' portfolio and increasing the exposure of the Series to the risks of high
yield securities.
    
 
HEDGING AND RETURN ENHANCEMENT STRATEGIES
 
    National Municipals Fund may also engage in various portfolio strategies,
including the purchase and sale of derivatives, to reduce certain risks of its
investments for bona fide hedging, risk management and return enhancement
purposes. These strategies include the purchase of put or tender options on
municipal bonds and notes and the purchase and sale of financial futures
contracts and options thereon and municipal bond index futures contracts.
National Municipals 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.
 
    Participation in the options and futures markets involves investment risks
and transaction costs to which National Municipals Fund would not be subject
absent the use of these strategies. National Municipals Fund's successful use of
financial futures contracts and options on futures contracts depends upon the
ability of its investment adviser to accurately predict movements in the
direction of interest rates and other factors affecting markets for securities.
For example, if National Municipals Fund has hedged against the possibility of
an increase in interest rates which would adversely affect the price of
securities in its portfolio and prices of such securities increase instead,
National Municipals Fund will lose part or all of the benefit of the increased
value of its securities because it will have offsetting losses in its futures
positions. In addition, in such situations, if National Municipals Fund has
insufficient cash to meet daily variation margin requirements, it may have to
sell securities to meet such requirements. Such sales of securities may be, but
will not necessarily be, at increased prices which reflect the rising market.
National Municipals Fund may have to sell securities at a time when it is
disadvantageous to do so. Where futures are purchased to hedge against a
possible increase in the price of securities before National Municipals Fund is
able to invest its cash in an orderly fashion, it is possible that the market
may decline instead. If National Municipals Fund then concludes not to invest in
securities at that time because of concern as to possible future market decline
or for other reasons, the Fund will realize a loss on the futures contract that
is not offset by a reduction in the price of the securities purchased.
 
    Each Series may also engage in various portfolio strategies, including the
purchase and sale of certain derivatives although the State Series may not do so
for return enhancement purposes. These strategies include the purchase of put
options and the purchase and sale of futures contracts and options thereon. Each
Series' participation in the options and futures markets subjects the Series to
similar types of hedging risks and, in the case of Intermediate Series, return
enhancement risks, as described above for National Municipals Fund. Subsequent
to the Reorganizations, shareholders of the State Series will be subject to the
additional risks associated with the use of derivatives for return enhancement.
 
                                       16
<PAGE>
LONG TERM BONDS
 
    National Municipals Fund primarily invests in long-term municipal bonds,
including obligations with longer maturities (E.G., 20 years or more). The State
Series invest in long-term obligations, and the dollar-weighted average maturity
of the Series will generally range between 10 and 20 years. Intermediate Series
invests primarily in municipal obligations with maturities between 3 and 15
years and will have a dollar-weighted average portfolio maturity of more than 3
and less than 10 years. Obligations with longer maturities generally offer both
higher yields and greater exposure to market fluctuation from changes in
interest rates than do those with shorter maturities.
 
TAX CONSIDERATIONS
 
    National Municipals Fund may purchase municipal obligations of any state,
territory or possession of the United States, or any political subdivision
thereof. As a result, upon consummation of the Reorganizations, shareholders of
the Maryland or Michigan Series that are residents in Maryland or Michigan,
respectively, will be subject to certain state income taxes with respect to that
portion of National Municipals Fund's income not earned from municipal
obligations the income from which is exempt from Maryland or Michigan state
income taxes. Shareholders of each Series are advised to consult their own tax
advisers regarding specific questions as to federal, state or local taxes. Each
of the Series and National Municipals Fund has elected to qualify, and intends
to remain qualified, as a regulated investment company under the Internal
Revenue Code.
 
    Interest on certain municipal bonds and municipal notes held by National
Municipals Fund may be subject to the federal alternative minimum tax. From time
to time, National Municipals 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.
 
REALIGNMENT OF INVESTMENT PORTFOLIO
 
    The portfolio manager of National Municipals Fund anticipates selling
certain securities in the investment portfolio of the combined Fund following
the consummation of such transaction. The portfolio manager of National
Municipals Fund expects that the sale of assets acquired from each Series and
the purchase of other securities may affect the aggregate amount of taxable
gains and losses generated by National Municipals Fund.
 
                            THE PROPOSED TRANSACTION
 
AGREEMENTS AND PLANS OF REORGANIZATION
 
    The terms and conditions under which the proposed transaction may be
consummated are set forth in the Plans. Significant provisions of the Plans are
summarized below; however, this summary is qualified in its entirety by
reference to the Plans, a copy of each of which is attached as Appendix B to
this Prospectus and Proxy Statement.
 
   
    The State Series Plan contemplates (i) National Municipals Fund acquiring
all of the assets of each of Maryland and Michigan Series in exchange for shares
of National Municipals Fund and the assumption by National Municipals Fund of
Maryland and Michigan Series' liabilities, if any, as of the Closing Date
(December 18, 1998, or such later date as the parties may agree) and (ii) the
constructive distribution on the date of the exchange, expected to occur on or
about the Closing Date, of Class A shares of National Municipals Fund to the
Class A, Class B and Class C shareholders of Maryland and Michigan Series as
provided for by the State Series Plan.
    
 
                                       17
<PAGE>
   
    The Intermediate Series Plan contemplates (i) National Municipals Fund
acquiring all of the assets of Intermediate Series in exchange for shares of
National Municipals Fund and the assumption by National Municipals Fund of
Intermediate Series' liabilities, if any, as of the Closing Date (December 18,
1998, or such later date as the parties may agree) and (ii) the constructive
distribution on the date of the exchange, expected to occur on or about the
Closing Date, of Class A, Class B, Class C and Class Z shares of National
Municipals Fund to the Class A, Class B, Class C and Class Z shareholders of
Intermediate Series as provided for by the Intermediate Series Plan.
    
 
   
    The assets of each Series to be acquired by National Municipals Fund shall
include, without limitation, all cash, cash equivalents, securities, receivables
(including interest and dividends receivable) and other property of any kind
owned by each Series and deferred or prepaid assets shown as assets on the books
of each Series. National Municipals Fund will assume from each Series all debts,
liabilities, obligations and duties of each Series of whatever kind or nature,
if any; provided, however, that each Series will utilize its best efforts, to
the extent practicable, to discharge all of its known debts, liabilities,
obligations and duties prior to the Closing Date. National Municipals Fund will
deliver to the State Series Class A shares of National Municipals Fund, which
the Maryland and Michigan Series will then distribute to their Class A, Class B
and Class C shareholders, respectively. National Municipals Fund will
simultaneously deliver to Intermediate Series Class A, Class B, Class C and
Class Z shares of National Municipals Fund which Intermediate Series will then
distribute to its Class A, Class B, Class C and Class Z shareholders,
respectively. Share certificates in National Municipals Fund will only be issued
upon written request to Prudential Mutual Fund Services LLC. See "Shareholder
Guide" in National Municipals Fund's Prospectus.
    
 
    The value of each Series' assets to be acquired and liabilities to be
assumed by National Municipals Fund and the net asset value of a share of
National Municipals Fund will be determined as of 4:15 P.M., New York time, on
the Closing Date in accordance with the valuation procedures of each respective
Fund's then current prospectus and statement of additional information.
 
    As soon as practicable after the Closing Date, Series Fund and Municipal
Bond Fund will terminate the State Series and Intermediate Series, respectively,
and distribute PRO RATA to each respective Series' shareholders of record the
applicable shares of National Municipals Fund received by each Series in
exchange for the applicable shareholders' interests in the Series evidenced by
their shares of beneficial interest of the Series and each Fund will file with
the Secretary of State of the Commonwealth of Massachusetts a Certificate of
Termination terminating each respective Series. Such distribution will be
accomplished by opening accounts on the books of National Municipals Fund in the
name of each Series' shareholders and by transferring thereto the shares of
National Municipals Fund previously credited to the account of each Series on
those books. Each shareholder account shall represent the respective PRO RATA
number of National Municipals Fund shares of common stock due to such Series
shareholder. Fractional shares of National Municipals Fund will be rounded to
the third decimal place.
 
   
    Accordingly, each shareholder of Class A, Class B and Class C shares of the
State Series will own Class A shares of National Municipals Fund immediately
after the Reorganizations that, except for rounding, will be equal to the value
immediately prior to the Reorganizations of that shareholder's Class A, Class B
or Class C shares of Maryland and Michigan Series. Each Class A, Class B, Class
C and Class Z shareholder of the Intermediate Series will own Class A, Class B,
Class C and Class Z shares, respectively, of National Municipals Fund
immediately after the Reorganizations that, except for rounding, will be equal
to the value of that shareholder's Class A, Class B, Class C and Class Z shares,
respectively, of Intermediate Series immediately prior to the Reorganizations.
Moreover, because shares of National Municipals Fund will be issued at net asset
value in exchange for net assets of each Series that, except for rounding, will
equal
    
 
                                       18
<PAGE>
the aggregate value of those shares, the net asset value per share of National
Municipals Fund will be unchanged. Thus the Reorganizations will not result in a
dilution of the value of any shareholder account. However, in general, the
Reorganizations will substantially reduce the percentage of ownership of each
shareholder of the Series below such shareholder's current percentage of
ownership in that Series because, while such shareholder will have the same
dollar amount invested initially in National Municipals Fund that he or she had
invested in the Series, his or her investment will represent a smaller
percentage of the combined net assets of National Municipals Fund and the
Series.
 
    Any transfer taxes payable upon issuance of shares of National Municipals
Fund in a name other than that of the registered holder of the shares on the
books of each Series as of that time shall be paid by the person to whom such
shares are to be issued as a condition of such transfer. Any reporting
responsibility of each Series will continue to be the responsibility of each
Series up to and including the Closing Date and such later date on which each
Series is terminated.
 
    On the effective date of the Reorganizations, the name of National
Municipals Fund will be unchanged.
 
    The consummation of the proposed transactions is subject to a number of
conditions set forth in the Plans, some of which may be waived by the Directors
of National Municipals Fund and the Trustees of Series Fund and the Trustees of
Municipal Bond Fund. The Plans may be terminated and the proposed transactions
abandoned at any time with respect to one or more Series, before or after
approval by the shareholders of each Series, prior to the Closing Date. In
addition, the Plans may be amended with respect to each Series in any mutually
agreeable manner, except that no amendment may be made subsequent to the Meeting
of shareholders of each Series that would detrimentally affect the value of
National Municipals Fund shares to be distributed to each Series' shareholders.
 
REASONS FOR THE REORGANIZATIONS CONSIDERED BY THE TRUSTEES/DIRECTORS
 
    The Trustees of Series Fund and the Trustees of Municipal Bond Fund,
including a majority of the Independent Trustees, have determined that the
interests of each Series' shareholders will not be diluted as a result of the
proposed transaction and that the proposed transaction is in the best interests
of the shareholders of the respective Series. In addition, the Directors of
National Municipals Fund, including a majority of the Independent Directors,
have determined that the interests of National Municipals Fund shareholders will
not be diluted as a result of the proposed transaction and that the proposed
transactions are in the best interests of the shareholders of National
Municipals Fund.
 
    The reasons that the Reorganizations were proposed by PIFM are described
above under "Synopsis-- Reasons for the Reorganizations." The Trustees of Series
Fund and the Trustees of Municipal Bond Fund and the Directors of National
Municipals Fund based their decisions to approve the Plans on an inquiry into a
number of factors, including the following:
 
        (1) The compatibility of the investment objectives, policies and
    restrictions of National Municipals Fund and each respective Series, and the
    fact that National Municipals Fund's portfolio is less susceptible to the
    risks associated with investments concentrated in a single state;
 
        (2) the relative past and current growth in assets, historical
    investment performance and perceived future prospects of National Municipals
    Fund and each of the Series;
 
        (3) the effect of the proposed transactions on the expense ratios of
    National Municipals Fund and each of the Series;
 
                                       19
<PAGE>
        (4) the costs of the Reorganizations, which will be paid for by National
    Municipals Fund and each of the Series in proportion to their respective
    asset levels;
 
        (5) the tax-free nature of the Reorganizations to National Municipals
    Fund, each of the Series and their shareholders;
 
        (6) with respect to the State Series Plan, if such Plan is approved,
    former shareholders of Maryland and Michigan Series, who would have
    otherwise received income generally exempt from Maryland or Michigan
    taxation, respectively, from Maryland and Michigan Series, will be subject
    to Maryland and Michigan state taxation on income derived from National
    Municipals Fund following each Reorganization;
 
        (7) the potential benefits to the shareholders of each of the Series and
    National Municipals Fund; and
 
        (8) other options to each Reorganization, including a continuance of a
    Series in its present form, a change of manager or investment objective or a
    termination of a Series with the distribution of the cash proceeds to the
    Series shareholders.
 
    If a Plan is not approved by shareholders of any of the Series, Series
Fund's Trustees and Municipal Bond Fund's Trustees may consider other
appropriate action, such as the termination of the applicable Series or a merger
or other business combination with an investment company other than National
Municipals Fund. The Shareholders of each Series vote separately on the
respective Plan and the Reorganization of any Series into National Municipals
Fund is not contingent on the Plan being approved by any other Series.
 
DESCRIPTION OF SECURITIES TO BE ISSUED
 
    National Municipals Fund's shares represent shares of common stock with $.01
par value per share. Shares of National Municipals Fund will be issued to each
Series' shareholders on the Closing Date as considered in each Plan. Each share
represents an equal and proportionate interest in National Municipals Fund with
each other share of the same class. Shares entitle their holders to one vote per
full share and fractional votes for fractional shares held. Each share of
National Municipals Fund has equal voting, dividend and liquidation rights with
other shares, except that each class has exclusive voting rights with respect to
its distribution plan, as noted under "Synopsis--Structure of the Series and
National Municipals Fund" above. Dividends paid by National Municipals Fund with
respect to each class of shares, to the extent any 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.
 
TAX CONSIDERATIONS
 
    The Fund will have received opinions on the Closing Date from Swidler Berlin
Shereff Friedman, LLP to the effect that (1) the proposed transactions described
above will constitute reorganizations within the meaning of Section 368(a)(1)(C)
of the Internal Revenue Code; (2) no gain or loss will be recognized by
shareholders of the Series upon liquidation of each Series and the distribution
of shares of National Municipals Fund constructively in exchange for their
shares of that Series (Internal Revenue Code Section 354(a)(1)); (3) no gain or
loss will be recognized by each Series upon the transfer of that Series' assets
to National Municipals Fund in exchange solely for shares of National Municipals
Fund and the assumption by National Municipals Fund of such Series' liabilities,
if any, and the subsequent distribution of those shares to that Series'
shareholders in liquidation thereof (Internal Revenue Code Sections 361(a) and
357(a)); (4) no
 
                                       20
<PAGE>
gain or loss will be recognized by National Municipals Fund upon the receipt of
such assets in exchange solely for National Municipals Fund's shares and its
assumption of the Series' liabilities, if any (Internal Revenue Code Section
1032(a)); (5) National Municipals Fund's basis for the assets received pursuant
to each Reorganization will be the same as the basis thereof in the hands of
each Series immediately before the Reorganization, and the holding period of
those assets in the hands of National Municipals Fund will include the holding
period thereof in each Series' hands (Internal Revenue Code Sections 362(b) and
1223(2)); (6) each Series' shareholders' basis for the shares of National
Municipals Fund to be received by them pursuant to each Reorganization will be
the same as their basis for the shares of each Series to be constructively
surrendered in exchange therefor (Internal Revenue Code Section 358(a)(1)); and
(7) the holding period of the shares of National Municipals Fund to be received
by the shareholders of each Series pursuant to each Reorganization will include
the period during which the shares of each Series to be constructively
surrendered in exchange therefor were held, provided the latter shares were held
as capital assets by the shareholders on the date of the exchange (Internal
Revenue Code Section 1223(1)). It should be noted that no rulings have been
sought by the IRS and that an opinion of counsel is not binding on the IRS or
any court. If the IRS were to successfully assert that the proposed transaction
is taxable, then the proposed transactions would be treated as taxable sales of
each Series' assets to National Municipals Fund followed by the taxable
liquidation of each Series, and shareholders of each Series would recognize gain
or loss as a result of such transaction.
 
CERTAIN OTHER COMPARATIVE INFORMATION ABOUT THE FUNDS
 
    National Municipals Fund is a Maryland corporation and the rights of its
shareholders are governed by its Articles of Incorporation, By-Laws and the
Maryland General Corporation Law. Series Fund and Municipal Bond Fund are each a
Massachusetts business trust and the rights of each Fund's shareholders are
governed by that Fund's Declaration of Trust, By-Laws and applicable
Massachusetts law. Certain relevant differences between the two forms of
organization are summarized below.
 
   
    CAPITALIZATION.  National Municipals Fund has issued shares of common stock,
par value $.01 per share. Its Articles of Incorporation authorize National
Municipals Fund to issue one billion shares of common stock divided into four
classes, consisting of 250 million authorized Class A shares, 250 million
authorized Class B shares, 250 million authorized Class C shares and 250 million
authorized Class Z shares. Series Fund and Municipal Bond Fund each has issued
shares of beneficial interest, par value $.01 per share, currently divided into
thirteen series and three series, respectively. Series Fund's Declaration of
Trust authorizes the State Series to issue an unlimited number of shares of
beneficial interest, divided into three classes, designated Class A, Class B and
Class C shares. Municipal Bond Fund's Declaration of Trust authorizes Municipal
Bond Fund to issue an unlimited number of shares of beneficial interest, divided
into four classes, designated Class A, Class B, Class C and Class Z shares.
National Municipals Fund and Intermediate Series currently offer Class A, Class
B, Class C and Class Z shares. The State Series currently offer Class A, Class B
and Class C shares. The Board of Directors of National Municipals Fund may
authorize an increase in the number of authorized shares and the Board of
Directors/Trustees of each Fund may reclassify unissued shares to authorize
additional classes of shares having terms and rights determined by its Board of
Directors/Trustees, all without shareholder approval.
    
 
    SHAREHOLDER MEETINGS AND VOTING RIGHTS.  Generally, none of the Funds is
required to hold annual meetings of its shareholders. Each Fund is required to
call a meeting of shareholders for the purpose of voting upon the question of
removal of a Director/Trustee or to transact any other business when requested
 
                                       21
<PAGE>
in writing to do so by the holders of at least 10% of the Fund's outstanding
shares. In addition, each Fund is required to call a meeting of shareholders for
the purpose of electing Directors/Trustees if, at any time, less than a majority
of the Directors/Trustees holding office at the time were elected by
shareholders.
 
    Under each of the Declarations of Trust of Municipal Bond Fund and Series
Fund, shareholders are entitled to vote only with respect to the following
matters: (1) the election or removal of Trustees if a meeting is called for such
purpose; (2) the adoption of any contract for which shareholder approval is
required by the Investment Company Act; (3) any amendment of the Declaration of
Trust, other than amendments to change the Fund's name, authorize additional
series of shares, supply any omission or cure, correct or supplement any
ambiguity or defective or inconsistent provision contained therein; (4) any
termination or reorganization of the Fund to the extent and as provided in the
Declaration of Trust; (5) a determination as to whether a court action,
proceeding or claim should or should not be brought or maintained derivatively
or as a class action on behalf of the applicable Fund or its shareholders, to
the same extent as the shareholders of a Massachusetts business corporation
would be entitled to vote on such a determination; (6) with respect to any plan
of distribution adopted pursuant to Rule 12b-1 under the Investment Company Act;
and (7) such additional matters relating to the applicable Fund as may be
required by law, the applicable Fund's Declaration of Trust, By-Laws, or any
registration of the applicable Fund with the Commission or any state securities
commission, or as the Trustees may consider necessary or desirable. Each Fund's
shareholders also vote upon changes in fundamental investment policies or
restrictions.
 
    Each Declaration of Trust provides that a "Majority Shareholder Vote" of the
Fund is required to decide any question. "Majority Shareholder Vote" means the
vote of the holders of a majority of shares, which shall consist of: (i) a
majority of shares represented in person or by proxy and entitled to vote at a
meeting of shareholders at which a quorum, as determined in accordance with the
By-Laws, is present; (ii) a majority of shares issued and outstanding and
entitled to vote when action is taken by written consent of shareholders; or
(iii) a "majority of the outstanding voting securities," as that phrase is
defined in the Investment Company Act, when action is taken by shareholders with
respect to approval of an investment advisory or management contract or an
underwriting or distribution agreement or continuance thereof.
 
    Shareholders in National Municipals Fund are entitled to one vote for each
share on all matters submitted to a vote of its shareholders under Maryland law.
Approval of certain matters, such as an amendment to the charter, a merger,
consolidation or transfer of all or substantially all assets, dissolution and
removal of a Director, requires the affirmative vote of a majority of the votes
entitled to be cast. A plurality of votes cast is required to elect Directors.
Other matters require the approval of the affirmative vote of a majority of the
votes cast at a meeting at which a quorum is present.
 
    Series Fund's, Municipal Bond Fund's and National Municipals Fund's By-Laws
each provide that a majority of the outstanding shares shall constitute a quorum
for the transaction of business at a shareholders' meeting. Matters requiring a
larger vote by law or under the organization documents for any of the Funds are
not affected by such quorum requirements.
 
    SHAREHOLDER LIABILITY.  Under Maryland law, National Municipals Fund's
shareholders have no personal liability as such for National Municipals Fund's
acts or obligations.
 
    Under Massachusetts law, Series Fund's and Municipal Bond Fund's
shareholders, under certain circumstances, could be held personally liable for
their respective Fund's obligations. However, each Declaration of Trust of
Series Fund and Municipal Bond Fund disclaims shareholder liability for acts or
obligations of each Fund and requires that notice of such disclaimer be given in
each note, bond, contract, order, agreement, obligation or instrument entered
into or executed by such Fund or its Trustees. Each
 
                                       22
<PAGE>
Fund's Declaration of Trust provides for indemnification out of such Fund's
property for all losses and expenses of any shareholder held personally liable
for such Fund's obligations solely by reason of his or her being or having been
a Fund shareholder and not because of his or her acts or omissions or some other
reason. Thus, each such Fund considers the risk of a shareholder incurring
financial loss on account of shareholder liability to be remote since it is
limited to circumstances in which a disclaimer is inoperative or the Fund itself
would be unable to meet its obligations.
 
    LIABILITY AND INDEMNIFICATION OF DIRECTORS AND TRUSTEES.  Under Maryland
law, a Director or officer of National Municipals Fund is not liable to National
Municipals Fund or its shareholders for monetary damages for breach of fiduciary
duty as a Director or officer except to the extent such exemption from liability
or limitation thereof is not permitted by law, including the Investment Company
Act. National Municipals Fund's By-Laws provide that its Directors and officers
will not be liable to National Municipals Fund, and may be indemnified for
liabilities, for any action or failure to act, except for bad faith, willful
misfeasance, gross negligence or reckless disregard of duties.
 
    The Declaration of Trust of Series Fund and Municipal Bond Fund provides
that no Trustee or officer of such Fund shall be liable to the Trust or
shareholders for any action or failure to act, except for bad faith, willful
misfeasance, gross negligence or reckless disregard of duties. Under such Fund's
Declaration of Trust, a Trustee is entitled to indemnification against all
liability and expenses reasonably incurred by him or her in connection with the
defense or disposition of any threatened or actual proceeding by reason of his
or her being or having been a Trustee provided, generally, such Trustee acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the Fund.
 
    Under the Investment Company Act, a Director of National Municipals Fund and
a Trustee of Series Fund and Municipal Bond Fund may not be protected against
liability to National Municipals Fund, Series Fund or Municipal Bond Fund,
respectively, and their security holders to which he or she would otherwise be
subject as a result of his or her willful misfeasance, bad faith or gross
negligence in the performance of his or her duties, or by reason of reckless
disregard of his or her obligations and duties. The staff of the Commission
interprets the Investment Company Act to require additional limits on
indemnification of Directors, Trustees and officers.

                               VOTING INFORMATION
 
    If the accompanying form of Proxy is executed properly and returned, shares
represented by it will be voted at the Meeting in accordance with the
instructions on the Proxy. However, if no instructions are specified, shares
will be voted for the proposal. A Proxy may be revoked at any time prior to the
time it is voted by written notice to the Secretary of Series Fund or the
Secretary of Municipal Bond Fund, as applicable, or by attendance at the
Meeting. If sufficient votes to approve the proposal are not received, the
persons named as proxies may propose one or more adjournments of the Meeting to
permit further solicitation of Proxies. Any such adjournment will require the
affirmative vote of a majority of those shares present at the Meeting or
represented by proxy. Any questions as to an adjournment of the Meeting will be
voted on by the persons named in the enclosed Proxy in the same manner that the
Proxies are instructed to be voted. In the event that the Meeting is adjourned,
the same procedures will apply at a later Meeting date.
 
    If a Proxy that is properly executed and returned is accompanied by
instructions to withhold authority to vote (an abstention) or represents a
broker "non-vote" (that is, a Proxy from a broker or nominee indicating that
such person has not received instructions from the beneficial owner or other
person entitled to vote shares on a particular matter with respect to which the
broker or nominee does not have discretionary power), the shares represented
thereby will be considered present for purposes of determining the existence of
a quorum for the transaction of business. Because approval of each proposed
Reorganization requires the affirmative vote of a majority of the total shares
outstanding of the respective Series, an abstention or broker non-vote will have
the effect of a vote against such proposed matters.
 
   
    The close of business on November 20, 1998 has been fixed as the record date
for the determination of shareholders entitled to notice of, and to vote at, the
Series' Meeting. On that date, Maryland Series had 1,573,704 Class A shares,
997,676 Class B shares and 10,799 Class C shares outstanding and entitled to
vote; Michigan Series had 2,429,718 Class A, 1,730,468 Class B and 42,385 Class
C shares outstanding and entitled to vote; and Intermediate Series had 1,256,177
Class A, 1,959,297 Class B, 42,438 Class C and 175,765 Class Z shares
outstanding and entitled to vote.
    
 
   
    Each share of each Series will be entitled to one vote at the Series'
Meeting. It is expected that the Notice of Special Meeting, Prospectus and Proxy
Statement and form of Proxy will be mailed to the Series' shareholders on or
about November 27, 1998.

    The expenses of reorganization and solicitation will be borne by Series
Fund, Municipal Bond Fund and National Municipals Fund in proportion to their
respective assets and will include reimbursement to brokerage firms and others
for expenses in forwarding proxy solicitation material to shareholders. The
Trustees of Series Fund have retained Shareholder Communications Corporation, a
proxy solicitation firm, to assist in the solicitation of Proxies for the
Meeting. The fees and expenses of Shareholder Communications Corporation
 
                                       31
<PAGE>
are not expected to exceed $11,000, excluding mailing and printing costs. The
solicitation of Proxies will be largely by mail but may include telephonic,
telegraphic or oral communication by regular employees of Prudential Securities
and its affiliates, including PIFM. This cost, including specified expenses,
also will be borne by Series Fund, Municipal Bond Fund and National Municipals
Fund in proportion to their respective assets.
 
                                 OTHER MATTERS
 
    No business other than as set forth herein is expected to come before the
Meeting, but should any other matter requiring a vote of shareholders of each
Series arise, including any question as to an adjournment of the Meeting, the
persons named in the enclosed Proxy will vote thereon according to their best
judgment in the interests of each Series, taking into account all relevant
circumstances.
 
                            SHAREHOLDERS' PROPOSALS
 
    A shareholder proposal intended to be presented at any subsequent meeting of
the shareholders of the State Series or Intermediate Series must be received by
Series Fund or Municipal Bond Fund, respectively, a reasonable time before the
Trustees' solicitation relating to such meeting is made in order to be included
in the Series' Proxy Statement and form of Proxy relating to that meeting. The
mere submission of a proposal by a shareholder does not guarantee that such
proposal will be included in the proxy statement because certain rules under the
federal securities laws must be complied with before inclusion of the proposal
is required. In the event that the Plans are approved at this Meeting with
respect to each Series, it is not expected that there will be any future
shareholder meetings of the Series.
 
    It is the present intent of the Board of Directors of National Municipals
Fund and the Trustees of Series Fund and the Trustees of Municipal Bond Fund not
to hold annual meetings of shareholders unless the election of
Directors/Trustees is required under the Investment Company Act nor to hold
special meetings of shareholders unless required by the Investment Company Act
or state law.

Appendix A

Prudential National Municipals Fund, Inc.

PERFORMANCE AT A GLANCE.

Long-term interest rates declined (and bond prices rose) in the U.S. as
inflation remained mild in 1997.  Municipal bonds also indirectly benefited when
investors sought more dependable securities in the wake of an Asian economic
crisis. Your Prudential National Municipals Fund beat the Lipper Average by
investing in higher yielding bonds and non-callable bonds that gained sharply as
interest rates fell.

Past performance is not indicative of future results. Principal and investment
return will fluctuate so that an investor's shares, when redeemed, may be worth
more or less than their original cost. 

(1) Source: Prudential Investments Fund Management and Lipper Analytical 
Services. The cumulative total returns do not take into account sales 
charges. The average annual returns do take into account applicable sales 
charges. The Fund charges a maximum front-end sales load of 3% for Class A 
shares and a declining, six-year contingent deferred sales charge (CDSC) of 
5%, 4%, 3%, 2%, 1% and 1% for Class B shares.  Class C shares have a 1% CDSC 
for one year. Without waiver of management fees and/or expense subsidization, 
the Fund's return would have been lower as indicated by the numbers in the ()
parentheses.  Class B shares automatically convert to Class A shares on a 
quarterly basis, after approximately seven years.

(2) Inception dates: Class A, 1/22/90; Class B, 4/25/80; and Class C, 8/1/94.

(3) Lipper General Muni Fund Average is based on the average of all funds in
this category for one-, five- and 10-year periods.

(4) Some investors may be subject to the federal alternative minimum tax and/or
state and local taxes.  Taxable equivalent yields reflect federal taxes only.

***Lipper Since Inceptions returns were: Class A, 82.75%; Class B, 373.53; and
Class C, 27.95% for all funds in each Lipper share class.

Source: Lipper Analytical Services. Financial markets change, so a mutual fund's
past performance should never be used to predict future results. The risks to
each of the investments listed above are different - we provide 12-month total
returns for several Lipper mutual fund categories to show you that reaching for
higher yields means tolerating more risk. The greater the risk, the larger the
potential reward or loss. In addition, we've included historical 20-year average
annual returns. These returns assume the reinvestment of dividends.

U.S. Growth Funds will fluctuate a great deal. Investors have received higher
historical total returns from stocks than from most other investments. Smaller
capitalization stocks offer greater potential for long-term growth but may be
more volatile than larger capitalization stocks.

General Bond Funds provide more income than stock funds, which can help smooth
out their total returns year by year. But their prices still fluctuate
(sometimes significantly) and their returns have been historically lower than
those of stock funds. 

General Municipal Debt Funds invest in bonds issued by state governments, 
state agencies and/or municipalities. This investment provides income that is 
usually exempt from federal and state income taxes.

U.S. Taxable Money Funds attempt to preserve a constant share value; they 
don't fluctuate much in price but, historically, their returns have been 
generally among the lowest of the major investment categories.

Prudential National Municipals Fund, Inc. 

PERFORMANCE AT A GLANCE.

A bountiful supply of new municipal bonds were issued by state and local
governments to take advantage of low borrowing costs over the past six months.
Despite the large supply, we encountered difficulty finding attractively priced,
medium-quality bonds to enhance our return to you. Then too, portfolio duration
(a measure of sensitivity to changing interest rates) was not longer than the
average fund so the Prudential National Municipal Fund did not gain as rapidly
as it could have when bond prices rose. As a result, the Fund's Class A shares
returned 2.21% compared to 2.26% for the Lipper General Municipal Average.

return will fluctuate so that an investor's shares, when redeemed, may be worth
more or less than their original cost.

The average annual total returns do take into account applicable sales charges.
The Fund charges a maximum front-end sales load of 3% for Class A shares and a
declining contingent deferred sales charge (CDSC) of 5%, 4%, 3%, 2%, 1% and 1%
for six years for Class B shares. Class B shares will automatically convert to
Class A shares, on a quarterly basis, approximately seven years after purchase.
Class C shares have a 1% CDSC for one year. Without waiver of management fees

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
    Agreement and Plan of Reorganization (Agreement) made as of the 25th day of
November, 1998, by and between Prudential Municipal Bond Fund (Municipal Bond
Fund)--Intermediate Series and Prudential National Municipals Fund, Inc.
(National Municipals Fund) (collectively, with Intermediate Series and Municipal
Bond Fund, the Funds and each individually, a Fund). Municipal Bond Fund is a
business trust organized under the laws of the Commonwealth of Massachusetts and
the National Municipals Fund is a corporation organized under the laws of the
State of Maryland. Each Fund maintains its principal place of business at
Gateway Center Three, Newark, New Jersey 07102. Shares of National Municipals
Fund and Intermediate Series are divided into four classes, designated Class A,
Class B, Class C and Class Z. Municipal Bond Fund consists of three series, one
of which is Intermediate Series.
    
 
    This Agreement is intended to be, and is adopted as, a plan of
reorganization pursuant to Section 368(a)(1)(C) of the Internal Revenue Code of
1986, as amended (Internal Revenue Code). Upon receipt of such representations
from each of the Funds as Swidler Berlin Shereff Friedman, LLP may require,
Swidler Berlin Shereff Friedman, LLP will deliver the opinion referenced in
paragraph 8.6 herein. The reorganization will comprise the transfer of the
assets of Intermediate Series in exchange for shares of common stock of National
Municipals Fund, and National Municipals Fund's assumption of such Series'
liabilities, if any, and the constructive distribution, after the Closing Date
hereinafter referred to, of such shares of National Municipals Fund to the
shareholders of Intermediate Series, and the termination of Intermediate Series
as provided herein, all upon the terms and conditions as hereinafter set forth.
 
    In consideration of the premises and of the covenants and agreements set
forth herein, the parties covenant and agree as follows:
 
1.  TRANSFER OF ASSETS OF INTERMEDIATE SERIES IN EXCHANGE FOR SHARES OF NATIONAL
    MUNICIPALS FUND AND ASSUMPTION OF LIABILITIES, IF ANY, AND TERMINATION OF
    INTERMEDIATE SERIES
 
   
1.1  Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, Municipal Bond Fund on
behalf of Intermediate Series agrees to sell, assign, transfer and deliver the
assets of Intermediate Series, as set forth in paragraph 1.2, to National
Municipals Fund, and National Municipals Fund agrees (a) to issue and deliver to
Intermediate Series in exchange therefor the number of shares of Class A, Class
B, Class C and Class Z shares of Common Stock in National Municipals Fund
determined by dividing the net asset value of the Intermediate Series allocable
to Class A, Class B, Class C and Class Z shares of beneficial interest (computed
in the manner and as of the time and date set forth in paragraph 2.1) by the net
asset value allocable to a share of National Municipals Fund Class A, Class B,
Class C and Class Z shares of Common Stock (computed in the manner and as of the
time and date set forth in paragraph 2.2); and (b) to assume all of Intermediate
Series' liabilities, if any, as set forth in paragraph 1.3. Such transactions
shall take place at the closing provided for in paragraph 3 (Closing).
    
 
1.2  The assets of Intermediate Series to be acquired by National Municipals
Fund shall include without limitation all cash, cash equivalents, securities,
receivables (including interest and dividends receivable) and other property of
any kind owned by such Series and any deferred or prepaid expenses shown as
assets on the
 
                                     B-1(A)
<PAGE>
books of such Series on the closing date provided in paragraph 3 (Closing Date).
National Municipals Fund has no plan or intent to sell or otherwise dispose of
any assets of Intermediate Series, other than in the ordinary course of
business.
 
1.3  Except as otherwise provided herein, National Municipals Fund will assume
all debts, liabilities, obligations and duties of Intermediate Series of
whatever kind or nature, whether absolute, accrued, contingent or otherwise,
whether or not determinable as of the Closing Date and whether or not
specifically referred to in this Agreement; provided, however, that Intermediate
Series agrees to utilize its best efforts to cause such Series to discharge all
of the known debts, liabilities, obligations and duties of such Series prior to
the Closing Date.
 
1.4  On or immediately prior to the Closing Date, Intermediate Series will
declare and pay to its shareholders of record dividends and/or other
distributions so that it will have distributed substantially all (and in any
event not less than ninety-eight percent) of each of such Series' investment
company taxable income (computed without regard to any deduction for dividends
paid), net tax-exempt interest income, if any, and realized net capital gains,
if any, for all taxable years through its termination.
 
   
1.5  On a date (Termination Date), as soon after the Closing Date as is
conveniently practicable, but in any event within 30 days of the Closing Date,
Intermediate Series will distribute PRO RATA to its Class A, Class B, Class C
and Class Z shareholders of record, determined as of the close of business on
the Closing Date, the Class A, Class B, Class C and Class Z shares of National
Municipals Fund received by Intermediate Series pursuant to paragraph 1.1 in
exchange for their interest in such Series, and Municipal Bond Fund will file
with the Secretary of State of The Commonwealth of Massachusetts a Certificate
of Termination terminating Intermediate Series. Such distribution will be
accomplished by opening accounts on the books of National Municipals Fund in the
names of Intermediate Series' shareholders and transferring thereto the shares
credited to the account of Intermediate Series on the books of National
Municipals Fund. Each account opened shall be credited with the respective PRO
RATA number of National Municipals Fund Class A, Class B, Class C and Class Z
shares due such Series' Class A, Class B, Class C and Class Z shareholders,
respectively. Fractional shares of National Municipals Fund shall be rounded to
the third decimal place.
    
 
1.6  National Municipals Fund shall not issue certificates representing its
shares in connection with such exchange. With respect to any Intermediate Series
shareholder holding Intermediate Series receipts for shares of beneficial
interest as of the Closing Date, until National Municipals Fund is notified by
Municipal Bond Fund's transfer agent that such shareholder has surrendered his
or her outstanding Series receipts for shares of beneficial interest or, in the
event of lost, stolen or destroyed receipts for shares of beneficial interest,
posted adequate bond or submitted a lost certificate form, as the case may be,
National Municipals Fund will not permit such shareholder to (1) receive
dividends or other distributions on National Municipals Fund shares in cash
(although such dividends and distributions shall be credited to the account of
such shareholder established on National Municipals Fund's books pursuant to
paragraph 1.5, as provided in the next sentence), (2) exchange National
Municipals Fund shares credited to such shareholder's account for shares of
other Prudential Mutual Funds, or (3) pledge or redeem such shares. In the event
that a shareholder is not permitted to receive dividends or other distributions
on National Municipals Fund shares in cash as provided in the preceding
sentence, National Municipals Fund shall pay such dividends or other
distributions in additional National Municipals Fund shares, notwithstanding any
election such shareholder shall have made previously with respect to the payment
of dividends or other distributions on shares of Intermediate Series.
Intermediate Series will, at its expense, request its shareholders to surrender
their outstanding Intermediate Series receipts for shares of beneficial
interest, post adequate bond or submit a lost certificate form, as the case may
be.
 
                                     B-2(A)
<PAGE>
1.7  Ownership of National Municipals Fund shares will be shown on the books of
the National Municipals Fund's transfer agent. Shares of National Municipals
Fund will be issued in the manner described in National Municipals Fund's
then-current prospectus and statement of additional information.
 
1.8  Any transfer taxes payable upon issuance of shares of National Municipals
Fund in exchange for shares of Intermediate Series in a name other than that of
the registered holder of the shares being exchanged on the books of Intermediate
Series as of that time shall be paid by the person to whom such shares are to be
issued as a condition to the registration of such transfer.
 
1.9  Any reporting responsibility with the Securities and Exchange Commission
(SEC) or any state securities commission of Municipal Bond Fund with respect to
Intermediate Series is and shall remain the responsibility of Intermediate
Series up to and including the Termination Date.
 
1.10  All books and records of Intermediate Series, including all books and
records required to be maintained under the Investment Company Act of 1940
(Investment Company Act) and the rules and regulations thereunder, shall be
available to National Municipals Fund from and after the Closing Date and shall
be turned over to National Municipals Fund on or prior to the Termination Date.
 
2.  VALUATION
 
2.1  The value of Intermediate Series' assets and liabilities to be acquired and
assumed, respectively, by National Municipals Fund shall be the net asset value
computed as of 4:15 p.m., New York time, on the Closing Date (such time and date
being hereinafter called the Valuation Time), using the valuation procedures set
forth in Intermediate Series' then-current prospectus and Municipal Bond Fund's
statement of additional information.
 
2.2  The net asset value of a share of National Municipals Fund shall be the net
asset value per such share computed on a class-by-class basis as of the
Valuation Time, using the valuation procedures set forth in National Municipals
Fund's then-current prospectus and statement of additional information.
 
2.3  The number of National Municipals Fund shares to be issued (including
fractional shares, if any) in exchange for Intermediate Series' net assets shall
be calculated as set forth in paragraph 1.1.
 
2.4  All computations of net asset value shall be made by or under the direction
of Prudential Investments Fund Management LLC (PIFM) in accordance with its
regular practice as manager of the Funds.
 
3.  CLOSING AND CLOSING DATE
 
   
3.1  The Closing Date shall be December 18, 1998 or such later date as the
parties may agree in writing. All acts taking place at the Closing shall be
deemed to take place simultaneously as of the close of business on the Closing
Date unless otherwise provided. The Closing shall be at the office of National
Municipals Fund or at such other place as the parties may agree.
    
 
3.2  State Street Bank and Trust Company (State Street), as custodian for
Intermediate Series, shall deliver to National Municipals Fund at the Closing a
certificate of an authorized officer of State Street stating that (a)
Intermediate Series' portfolio securities, cash and any other assets have been
transferred in proper form to National Municipals Fund on the Closing Date and
(b) all necessary taxes, if any, have been paid, or provision for payment has
been made, in conjunction with the transfer of portfolio securities.
 
3.3  In the event that immediately prior to the Valuation Time (a) the New York
Stock Exchange (NYSE) or other primary exchange is closed to trading or trading
thereon is restricted or (b) trading or the reporting of trading on the NYSE or
other primary exchange or elsewhere is disrupted so that accurate appraisal of
the
 
                                     B-3(A)
<PAGE>
value of the net assets of Intermediate Series and of the net asset value per
share of National Municipals Fund is impracticable, the Closing Date shall be
postponed until the first business day after the date when such trading shall
have been fully resumed and such reporting shall have been restored.
 
3.4  Municipal Bond Fund shall deliver to National Municipals Fund on or prior
to the Termination Date the names and addresses of each of the shareholders of
Intermediate Series and the number of outstanding shares owned by each such
shareholder, all as of the close of business on the Closing Date, certified by
the Secretary or Assistant Secretary of Municipal Bond Fund. National Municipals
Fund shall issue and deliver to Municipal Bond Fund at the Closing a
confirmation or other evidence satisfactory to Municipal Bond Fund that shares
of National Municipals Fund have been or will be credited to Intermediate
Series' account on the books of National Municipals Fund. At the Closing each
party shall deliver to the other such bills of sale, checks, assignments, share
certificates, receipts and other documents as such other party or its counsel
may reasonably request to effect the transactions contemplated by this
Agreement.

    been audited by PricewaterhouseCoopers LLP, independent accountants, in

    statements are prepared in accordance with generally accepted accounting
    principles and present fairly, in all material respects, the financial
    condition,

Appendix B
 
                     AGREEMENT AND PLAN OF REORGANIZATIONS
 
   
    Agreement and Plan of Reorganizations (Agreement) made as of the 25th day of
November, 1998, by and between Prudential Municipal Series Fund (Series
Fund)--Maryland Series and Michigan Series and Prudential National Municipals
Fund, Inc. (National Municipals Fund and, collectively with Series Fund, the
Funds and each individually, a Fund). The Series Fund is a business trust
organized under the laws of the Commonwealth of Massachusetts and the National
Municipals Fund is a corporation organized under the laws of the State of
Maryland. Each Fund maintains its principal place of business at Gateway Center
Three, Newark, New Jersey 07102. Shares of National Municipals Fund are divided
into four classes, designated Class A, Class B, Class C and Class Z. Shares of
Maryland Series and Michigan Series are divided into three classes, designated
Class A, Class B and Class C. Series Fund consists of thirteen series, two of
which are the Maryland Series and Michigan Series (collectively, the Series and
each individually, a Series).
    
 
    This Agreement is intended to be, and is adopted as, a plan of
reorganizations pursuant to Section 368(a)(1)(C) of the Internal Revenue Code of
1986, as amended (Internal Revenue Code). The reorganizations will comprise the
transfer of the assets of the Maryland Series and Michigan Series, respectively,
in exchange for shares of common stock of National Municipals Fund, and National
Municipals Fund's assumption of such Series' liabilities, if any, and the
constructive distribution, after the Closing Date hereinafter referred to, of
such shares of National Municipals Fund to the shareholders of the respective
Series, and the termination of the Series as provided herein, all upon the terms
and conditions as hereinafter set forth.
 
    In consideration of the premises and of the covenants and agreements set
forth herein, the parties covenant and agree as follows:
 
1.  TRANSFER OF ASSETS OF THE SERIES IN EXCHANGE FOR SHARES OF NATIONAL
    MUNICIPALS FUND AND ASSUMPTION OF LIABILITIES, IF ANY, AND TERMINATION OF
    THE SERIES
 
1.1  Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, Series Fund on behalf of
Maryland and Michigan Series agrees to sell, assign, transfer and deliver the
assets of each Series, as set forth in paragraph 1.2, to National Municipals
Fund, and National Municipals Fund agrees (a) to issue and deliver to each
Series in exchange therefor the number of shares of Class A Common Stock in
National Municipals Fund determined by dividing the net asset value of the
respective Series allocable to Class A, Class B and Class C shares of beneficial
interest (computed in the manner and as of the time and date set forth in
paragraph 2.1) by the net asset value allocable to a share of National
Municipals Fund Class A Common Stock (computed in the manner and as of the time
and date set forth in paragraph 2.2) and (b) to assume all of each Series'
liabilities, if any, as set forth in paragraph 1.3. Such transactions shall take
place at the closing provided for in paragraph 3 (Closing).
 
1.2  The assets of each Series to be acquired by National Municipals Fund shall
include without limitation all cash, cash equivalents, securities, receivables
(including interest and dividends receivable) and other property of any kind
owned by such Series and any deferred or prepaid expenses shown as assets on the
books of such Series on the closing date provided in paragraph 3 (Closing Date).
National Municipals Fund has no plan or intent to sell or otherwise dispose of
any assets of the Series, other than in the ordinary course of business.
 
                                     B-1(B)
<PAGE>
1.3  Except as otherwise provided herein, National Municipals Fund will assume
all debts, liabilities, obligations and duties of each Series of whatever kind
or nature, whether absolute, accrued, contingent or otherwise, whether or not
determinable as of the Closing Date and whether or not specifically referred to
in this Agreement; provided, however, that each Series agrees to utilize its
best efforts to cause such Series to discharge all of the known debts,
liabilities, obligations and duties of such Series prior to the Closing Date.
 
1.4  On or immediately prior to the Closing Date, each Series will declare and
pay to its shareholders of record dividends and/or other distributions so that
it will have distributed substantially all (and in any event not less than
ninety-eight percent) of each of such Series' investment company taxable income
(computed without regard to any deduction for dividends paid), net tax-exempt
interest income, if any, and realized net capital gains, if any, for all taxable
years through its termination.
 
   
1.5  On a date (Termination Date), as soon after the Closing Date as is
conveniently practicable, but in any event within 30 days of the Closing Date,
each Series will distribute PRO RATA to its Class A, Class B and Class C
shareholders of record, determined as of the close of business on the Closing
Date, the Class A shares of National Municipals Fund received by the Series
pursuant to paragraph 1.1 in exchange for their interest in such Series, and
Municipal Series Fund will file with the Secretary of State of The Commonwealth
of Massachusetts a Certificate of Termination terminating each Series. Such
distribution will be accomplished by opening accounts on the books of National
Municipals Fund in the names of each Series' shareholders and transferring
thereto the shares credited to the account of the respective Series on the books
of National Municipals Fund. Each account opened shall be credited with the
respective PRO RATA number of National Municipals Fund Class A shares due such
Series' Class A, Class B and Class C shareholders, respectively. Fractional
shares of National Municipals Fund shall be rounded to the third decimal place.
    
 
1.6  National Municipals Fund shall not issue certificates representing its
shares in connection with such exchange. With respect to any Series shareholder
holding Series receipts for shares of beneficial interest as of the Closing
Date, until National Municipals Fund is notified by Series Fund's transfer agent
that such shareholder has surrendered his or her outstanding Series receipts for
shares of beneficial interest or, in the event of lost, stolen or destroyed
receipts for shares of beneficial interest, posted adequate bond or submitted a
lost certificate form, as the case may be, National Municipals Fund will not
permit such shareholder to (1) receive dividends or other distributions on
National Municipals Fund shares in cash (although such dividends and
distributions shall be credited to the account of such shareholder established
on National Municipals Fund's books pursuant to paragraph 1.5, as provided in
the next sentence), (2) exchange National Municipals Fund shares credited to
such shareholder's account for shares of other Prudential Mutual Funds, or (3)
pledge or redeem such shares. In the event that a shareholder is not permitted
to receive dividends or other distributions on National Municipals Fund shares
in cash as provided in the preceding sentence, National Municipals Fund shall
pay such dividends or other distributions in additional National Municipals Fund
shares, notwithstanding any election such shareholder shall have made previously
with respect to the payment of dividends or other distributions on shares of the
Series. Each Series will, at its expense, request its shareholders to surrender
their outstanding Series receipts for shares of beneficial interest, post
adequate bond or submit a lost certificate form, as the case may be.
 
1.7  Ownership of National Municipals Fund shares will be shown on the books of
the National Municipals Fund's transfer agent. Shares of National Municipals
Fund will be issued in the manner described in National Municipals Fund's
then-current prospectus and statement of additional information.
 
                                     B-2(B)
<PAGE>
1.8  Any transfer taxes payable upon issuance of shares of National Municipals
Fund in exchange for shares of the Series in a name other than that of the
registered holder of the shares being exchanged on the books of that Series as
of that time shall be paid by the person to whom such shares are to be issued as
a condition to the registration of such transfer.
 
1.9  Any reporting responsibility with the Securities and Exchange Commission
(SEC) or any state securities commission of Series Fund with respect to a Series
is and shall remain the responsibility of the Series up to and including the
Termination Date.
 
1.10  All books and records of Series Fund, including all books and records
required to be maintained under the Investment Company Act of 1940, as amended
(Investment Company Act) and the rules and regulations thereunder, shall be
available to National Municipals Fund from and after the Closing Date and shall
be turned over to National Municipals Fund on or prior to the Termination Date.
 
2.  VALUATION
 
2.1  The value of each Series' assets and liabilities to be acquired and
assumed, respectively, by National Municipals Fund shall be the net asset value
computed as of 4:15 p.m., New York time, on the Closing Date (such time and date
being hereinafter called the Valuation Time), using the valuation procedures set
forth in such Series' then-current prospectus and Series Fund's statement of
additional information.
 
2.2  The net asset value of a share of National Municipals Fund shall be the net
asset value per such share computed on a class-by-class basis as of the
Valuation Time, using the valuation procedures set forth in National Municipals
Fund's then-current prospectus and statement of additional information.
 
2.3  The number of National Municipals Fund shares to be issued (including
fractional shares, if any) in exchange for the Series' net assets shall be
calculated as set forth in paragraph 1.1.
 
2.4  All computations of net asset value shall be made by or under the direction
of Prudential Investments Fund Management LLC (PIFM) in accordance with its
regular practice as manager of the Funds.
 
3.  CLOSING AND CLOSING DATE
 
   
3.1  The Closing Date shall be December 18, 1998 or such later date as the
parties may agree in writing. All acts taking place at the Closing shall be
deemed to take place simultaneously as of the close of business on the Closing
Date unless otherwise provided. The Closing shall be at the office of National
Municipals Fund or at such other place as the parties may agree.
    
 
3.2  State Street Bank and Trust Company (State Street), as custodian for each
Series, shall deliver to National Municipals Fund at the Closing a certificate
of an authorized officer of State Street stating that (a) the applicable Series'
portfolio securities, cash and any other assets have been transferred in proper
form to National Municipals Fund on the Closing Date and (b) all necessary
taxes, if any, have been paid, or provision for payment has been made, in
conjunction with the transfer of portfolio securities.
 
3.3  In the event that immediately prior to the Valuation Time (a) the New York
Stock Exchange (NYSE) or other primary exchange is closed to trading or trading
thereon is restricted or (b) trading or the reporting of trading on the NYSE or
other primary exchange or elsewhere is disrupted so that accurate appraisal of
the value of the net assets of the Series and of the net asset value per share
of National Municipals Fund is impracticable, the Closing Date shall be
postponed until the first business day after the date when such trading shall
have been fully resumed and such reporting shall have been restored.
 
                                     B-3(B)
<PAGE>
3.4  Series Fund shall deliver to National Municipals Fund on or prior to the
Termination Date the names and addresses of each of the shareholders of each
Series and the number of outstanding shares owned by each such shareholder, all
as of the close of business on the Closing Date, certified by the Secretary or
Assistant Secretary of Series Fund. National Municipals Fund shall issue and
deliver to Series Fund at the Closing a confirmation or other evidence
satisfactory to Series Fund that shares of National Municipals Fund have been or
will be credited to each Series' account on the books of National Municipals
Fund. At the Closing each party shall deliver to the other such bills of sale,
checks, assignments, share certificates, receipts and other documents as such
other party or its counsel may reasonably request to effect the transactions
contemplated by this Agreement.

                              GENERAL INFORMATION
 
  At a special meeting held on July 19, 1994, shareholders approved an 
amendment to the Fund's Articles of Incorporation to change the Fund's name 
from Prudential-Bache National Municipals Fund, Inc. to Prudential National 
Municipals Fund, Inc. 
 
                       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, the Fund intends to invest substantially all, and in any event at 
least 80%, of its total assets in Municipal Bonds and Municipal Notes, except 
in certain circumstances. From time to time the Fund may invest in 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" in the 
Prospectus. There can be no assurance that the Fund's investment objective will 
be achieved. For a further description of the Fund's investment objective and 
policies see "How the Fund Invests-Investment Objective and Policies" in the 
Prospectus. 
 
Municipal Notes
 
  For liquidity purposes, pending investment in Municipal Bonds, or on a 
temporary or defensive basis due to market conditions, the Fund may invest in 
tax-exempt short-term debt obligations (maturing in one year or less). These 
obligations, known as "Municipal Notes," include tax, revenue and bond 
anticipation notes which are issued to obtain funds for various public 
purposes. The interest from these Notes is exempt from federal income taxes. 
The Fund will limit its investments in Municipal Notes to (1) those which are 
rated, at the time of purchase, within the three highest grades assigned by 
Moody's Investors Service (Moody's) or the two highest grades assigned by 
Standard & Poor's Ratings Group (S&P) or comparably rated by any other 
Nationally Recognized Statistical Rating Organization (NRSRO); (2) those of 
issuers having, at the time of purchase, an issue of outstanding Municipal 
Bonds rated within the four highest grades of Moody's or S&P or comparably 
rated by any other NRSRO; or (3) those which are guaranteed by the U.S. 
Government, its agents or instrumentalities. 
 
Municipal Bonds
 
  Municipal Bonds include debt obligations of a state, a territory, or a 
possession of the United States, or any political subdivision thereof (e.g., 
counties, cities, towns, villages, districts, authorities) or the District of 
Columbia issued to obtain funds for various purposes, including the 
construction of a wide range of public facilities such as airports, bridges, 
highways, housing, hospitals, mass transportation, schools, streets and water 
and sewer works. Other public purposes for which Municipal Bonds may be issued 
include the refunding of outstanding obligations, obtaining funds for general 
operating expenses and the obtaining of funds to loan to public or private 
institutions for the construction of facilities such as education, hospital and 
housing facilities. In addition, certain types of private activity bonds may be 
issued by or on behalf of public authorities to obtain funds to provide 
privately-operated housing facilities, sports facilities, convention or trade 
show facilities, airport, mass transit, port or parking facilities, air or 
water pollution control facilities and certain local facilities for water 
supply, gas, electricity or sewage or solid waste disposal. Such obligations 
are included within the term Municipal Bonds if the interest paid thereon is at 
the time of issuance, in the opinion of the issuer's bond counsel, exempt from 
federal income tax. The current federal tax laws, however, substantially limit 
the amount of such obligations that can be issued in each state. See "Taxes, 
Dividends and Distributions." 
 
  The two principal classifications of Municipal Bonds are "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. 
Private activity bonds that are Municipal Bonds are in most cases revenue bonds 
and do not generally constitute the pledge of the credit of the issuer of such 
bonds. The credit quality of private activity revenue bonds is usually directly 
related to the credit standing of the industrial user involved. There are, in 
addition, a variety of hybrid and special types of municipal obligations as 
well as numerous differences in the security of Municipal Bonds, both within 
and between the two principal classifications described above. 
 
  The interest rates payable on certain Municipal Bonds and Municipal 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 
obligation prior to its stated maturity (a demand feature) and the right of the 
issuer to prepay the principal 
                                      B-2
 
<PAGE> 

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 NAV 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 will treat an investment in a municipal security refunded with 
escrowed U.S. Government securities as U.S. Government securities for purposes 
of the Investment Company Act's diversification requirements provided: (i) the 
escrowed securities are "government securities" as defined in the Investment 
Company Act, (ii) the escrowed securities are irrevocably pledged only to 
payment of debt service on the refunded securities, except to the extent there 
are amounts in excess of funds necessary for such debt service, (iii) principal 
and interest on the escrowed securities will be sufficient to satisfy all 
scheduled principal, interest and any premiums on the refunded securities and a 
verification report prepared by a party acceptable to a nationally recognized 
statistical rating agency, or counsel to the holders of the refunded 
securities, so verifies, (iv) the escrow agreement provides that the issuer of 
the refunded securities grants and assigns to the escrow agent, for the equal 
and ratable benefit of the holders of the refunded securities, an express first 
lien on, pledge of and perfected security interest in the escrowed securities 
and the interest income thereon, (v) the escrow agent had no lien of any type 
with respect to the escrowed securities for payment of its fees or expenses 
except to the extent there are excess securities, as described in (ii) above. 
The Fund will not, however, invest more than 25% of its total assets in 
pre-refunded bonds of the same municipal issuer. 
 
Purchase And Exercise of Puts
 
  Puts 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 or tender options. 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 or tender options. Such increased cost may be paid either by 
way of an initial or periodic premium for the put or tender option or by way of 
a higher purchase price for securities to which the put or tender option 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 four highest quality grades as 
determined by Moody's or 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 four 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 two highest quality grades of such rating services. 
 
Portfolio Turnover
 
  Although the Fund does not intend to engage in substantial short-term 
trading, it may sell portfolio securities without regard to the length of time 
that they have been held in order to take advantage of new investment 
opportunities or yield differentials or because the Fund desires to preserve 
gains or limit losses due to changing economic conditions or the financial 
condition of the issuer. In order to seek a high level of current income, the 
investment adviser intends to change the composition of the Fund's portfolio, 
adjusting maturities and the quality and type of issue. Accordingly, it is 
possible that the Fund's portfolio turnover rate may reach, or even exceed, 
150%. A portfolio turnover rate of 150% may exceed that of other investment 
companies with similar objectives. The portfolio turnover rate is computed by 
dividing the lesser of the amount of the securities purchased or securities 
sold (excluding all securities whose maturities at acquisition were one year or 
less) by the average monthly value of such securities owned during the year. A 
100% turnover rate would occur, for example, if all of the securities held in 
the Fund's portfolio were sold and replaced within one year. However, when 
portfolio changes are deemed appropriate due to market or other conditions, 
such turnover rate may be greater than anticipated. A higher rate of turnover 
results in increased transaction costs to the Fund. For the years ended 
December 31, 1996 and 1997 the Fund's portfolio turnover rates were 46% and 
38%, respectively. 
 
Financial Futures Contracts
 
  The Fund will engage in transactions in financial futures contracts for 
return enhancement and risk management purposes as well as to hedge against 
interest rate related fluctuations in the value of securities which are held in 
the Fund's portfolio or which the Fund intends to purchase. The Fund will 
engage in such transactions consistent with the Fund's investment objective. A 
clearing 
                                      B-3
 
<PAGE> 

corporation associated with the commodities exchange on which a futures 
contract trades assumes responsibility for the completion of transactions and 
guarantees that open futures contracts will be performed. Although interest 
rate futures contracts call for actual delivery or acceptance of debt 
securities, in most cases the contracts are closed out before the settlement 
date without the making or taking of delivery. 
 
  Options on Financial Futures. The Fund may enter into options on future 
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. 
 
  Limitations on Purchase and Sale. Under regulations of the Commodity Exchange 
Act, investment companies registered under the Investment Company Act of 1940, 
as amended (the Investment Company Act) are exempt from the definition of 
"commodity pool operator," subject to compliance with certain conditions. The 
Fund will only engage in futures transactions for bona fide hedging, risk 
management and return enhancement purposes in accordance with the rules of the 
Commodity Futures Trading Commission and not for speculation. With respect to 
long positions assumed by the Fund, the Fund will segregate an amount of cash 
or other liquid assets so that the amount so segregated plus the amount of 
initial and variation margin held in the account of its broker equals the 
market value of the futures contracts, and thereby insure that the use of 
futures contracts is unleveraged. The Fund will continue to invest at least 80% 
of its total assets in Municipal Bonds and Municipal Notes except in certain 
circumstances, as described in the Prospectus under "How the Fund 
Invests-Investment Objective and Policies." The Fund may not enter into futures 
contracts if, immediately thereafter, the sum of the amount of initial and net 
cumulative variation margin on outstanding futures contracts, together with 
premiums paid on options thereon, would exceed 20% of the total assets of the 
Fund. 
 
  Risks of Financial Futures Transactions. In addition to the risk associated 
with predicting movements in the direction of interest rates, discussed in "How 
the Fund Invests-Investment Objective and Policies" in the Prospectus, there 
are a number of other risks associated with the use of financial futures for 
hedging purposes. 
 
  Hedging involves the risk of imperfect correlation because changes in the 
price of futures contracts only generally parallel but do not necessarily equal 
changes in the prices of the securities being hedged. The risk of imperfect 
correlation increases as the composition of the Fund's securities portfolio 
diverges from the securities that are the subject of the futures contract, for 
example, those included in the municipal index. Because the change in price of 
the futures contract may be more or less than the change in prices of the 
underlying securities, even a correct forecast of interest rate changes may not 
result in a successful hedging transaction. 
 
  The Fund intends to purchase and sell futures contracts only on exchanges 
where there appears to be a market in such futures sufficiently active to 
accommodate the volume of its trading activity. There can be no assurance that 
a liquid market will always exist for any particular contract at any particular 
time. Accordingly, there can be no assurance that it will always be possible to 
close a futures position when such closing is desired; and in the event of 
adverse price movements, the Fund would continue to be required to make daily 
cash payments of variation margin. However, in the event futures contracts have 
been sold to hedge portfolio securities, such securities will not be sold until 
the offsetting futures contracts can be executed. Similarly, in the event 
futures have been bought to hedge anticipated securities purchases, such 
purchases will not be executed until the offsetting futures contracts can be 
sold. 
 
  The hours of trading of interest rate futures contracts may not conform to 
the hours during which the Fund may trade Municipal Bonds. To the extent that 
the futures markets close before the municipal bond market, significant price 
and rate movements can take place that cannot be reflected in the futures 
markets on a day-to-day basis. 
 
  Risks of Transactions in Options on Financial Futures. In addition to the 
risks which apply to all options transactions, there are several special risks 
relating to options on futures. The ability to establish and close out 
positions on such options will be subject to the maintenance of a liquid 
secondary market. Compared to the sale of financial futures, the purchase of 
put options on financial futures involves less potential risk to the Fund 
because the maximum amount at risk is the premium paid for the options (plus 
transaction costs). However, there may be circumstances when the purchase of a 
put option on a financial future would result in a loss to the Fund when the 
sale of a financial future would not, such as when there is no movement in the 
price of debt securities. 
 
  An option position may be closed out only on an exchange which provides a 
secondary market for an option of the same series. Although the Fund generally 
will purchase only those options for which there appears to be an active 
secondary market, there is no assurance that a liquid secondary market on an 
exchange will exist for any particular option, or at any particular time, and 
for some options, no secondary market on an exchange may exist. In such event, 
it might not be possible to effect closing transactions in 
                                      B-4
 
<PAGE> 

particular options, with the result that the Fund would have to exercise its 
options in order to realize any profit and would incur transaction costs upon 
the sale of underlying securities pursuant to the exercise of put options. 
 
  Reasons for the absence of a liquid secondary market on an exchange include 
the following: (i) there may be insufficient trading interest in certain 
options; (ii) restrictions may be imposed by an exchange on opening 
transactions or closing transactions or both; (iii) trading halts, suspensions 
or other restrictions may be imposed with respect to particular classes or 
series of options or underlying securities; (iv) unusual or unforeseen 
circumstances may interrupt normal operations on an exchange; (v) the 
facilities of an exchange or the Options Clearing Corporation may not at all 
times be adequate to handle current trading volume; or (vi) one or more 
exchanges could, for economic or other reasons, decide or be compelled at some 
future date to discontinue the trading of options (or a particular class or 
series of options), in which event the secondary market on that exchange (or in 
that class or series of options) would cease to exist, although outstanding 
options on that exchange that had been issued by the Options Clearing 
Corporation as a result of trades on that exchange could continue to be 
exercisable in accordance with their terms. 
 
  There is no assurance that higher than anticipated trading activity or other 
unforeseen events might not, at times, render certain of the facilities of the 
Options Clearing Corporation inadequate, and thereby result in the institution 
by an exchange of special procedures which may interfere with the timely 
execution of customers' orders. 
 
Illiquid Securities
 
  The Fund may not hold more than 15% of its net assets in repurchase 
agreements which have a maturity of longer than seven days or in other illiquid 
securities, including securities that are illiquid by virtue of the absence of 
a readily available market or contractual restrictions on resale. Repurchase 
agreements subject to demand are deemed to have a maturity equal to the notice 
period. Mutual funds do not typically hold a significant amount of illiquid 
securities because of the potential for delays on resale and uncertainty in 
valuation. Limitations on resale may have an adverse effect on the 
marketability of portfolio securities and a mutual fund might be unable to 
dispose of illiquid securities promptly or at reasonable prices and might 
thereby experience difficulty satisfying redemptions within seven days. 
 
  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. In reaching liquidity decisions, the investment adviser will 
consider, inter alia, the following factors: (1) the frequency of trades and 
quotes for the security; (2) the number of dealers wishing to purchase or sell 
the security and the number of other potential purchasers; (3) dealer 
undertakings to make a market in the security; and (4) the nature of the 
security and the nature of the marketplace trades (e.g., the time needed to 
dispose of the security, the method of soliciting offers and the mechanics of 
the transfer). With respect to municipal lease obligations, the investment 
adviser also considers: (1) the willingness of the municipality to continue, 
annually or biannually, to appropriate funds for payment of the lease; (2) the 
general credit quality of the municipality and the essentiality to the 
municipality of the property covered by the lease; (3) in the case of unrated 
municipal lease obligations, an analysis of factors similar to that performed 
by nationally recognized statistical rating organizations in evaluating the 
credit quality of a municipal lease obligation, including (i) whether the lease 
can be cancelled; (ii) if applicable, what assurance there is that the assets 
represented by the lease can be sold; (iii) the strength of the lessee's 
general credit (e.g., its debt, administrative, economic and financial 
characteristics); (iv) the likelihood that the municipality will discontinue 
appropriating funding for the leased property because the property is no longer 
deemed essential to the operations of the municipality (e.g., the potential for 
an event of nonappropriation); (v) the legal recourse in the event of failure 
to appropriate; and (4) any other factors unique to municipal lease obligations 
as determined by the investment adviser. 
 
Segregated Accounts
 
  When the Fund is required to segregate assets in connection with certain 
hedging transactions, it will maintain cash or liquid assets in a segregated 
account. "Liquid assets" means cash, U.S. Government securities, equity 
securities (including foreign securities), debt obligations or other liquid, 
unencumbered assets, marked-to-market daily. 
 
                            INVESTMENT RESTRICTIONS
 
  The following restrictions are fundamental policies. Fundamental policies are 
those which cannot be changed without the approval of the holders of a majority 
of the Fund's outstanding voting securities. A "majority of the Fund's 
outstanding voting securities," when used in this Statement of Additional 
Information, means the lesser of (i) 67% of the voting shares represented at a 
meeting at which more than 50% of the outstanding voting shares are present in 
person or represented by proxy or (ii) more than 50% of the outstanding voting 
shares. 
                                      B-5

  The Fund may not:
 
  (1) With respect to 75% of its total assets, invest more than 5% of the 
market or other fair value of its total assets in the securities of any one 
issuer (other than obligations of, or guaranteed by, the U.S. Government, its 
agencies or instrumentalities). It is the current policy (but not a fundamental 
policy) of the Fund not to invest more than 5% of the market or other fair 
value of its total assets in the securities of any one issuer. 
 
  (2) Make short sales of securities.
 
  (3) Purchase securities on margin, except for such short-term credits as are 
necessary for the clearance of purchases and sales of portfolio securities and 
margin payments in connection with transactions in financial futures contracts. 
 
  (4) Issue senior securities, borrow money or pledge its assets, except that 
the Fund may borrow up to 331/3% of the value of its total assets (calculated 
when the loan is made) for temporary, extraordinary or emergency purposes or 
for the clearance of transactions. The Fund may pledge up to 331/3% of the 
value of its total assets to secure such borrowings. Secured borrowings may 
take the form of reverse repurchase agreements, pursuant to which the Fund 
would sell portfolio securities for cash and simultaneously agree to repurchase 
them at a specified date for the same amount of cash plus an interest 
component. The Fund would maintain, in a segregated account with its Custodian, 
liquid assets equal in value to the amount owed. For purposes of this 
restriction, obligations of the Fund to Directors pursuant to deferred 
compensation arrangements, the purchase and sale of securities on a when-issued 
or delayed delivery basis, the purchase and sale of financial futures contracts 
and options and collateral arrangements with respect to margins for financial 
futures contracts and with respect to options are not deemed to be the issuance 
of a senior security or a pledge of assets. 
 
  (5) Engage in the underwriting of securities or purchase any securities as to 
which registration under the Securities Act of 1933 would be required for 
resale of such securities to the public. 
 
  (6) Purchase or sell real estate or real estate mortgage loans, although it 
may purchase Municipal Bonds or Notes secured by interests in real estate. 
 
  (7) Make loans of money or securities except through the purchase of debt 
obligations or repurchase agreements. 
 
  (8) Purchase securities of other investment companies, except in the open 
market involving any customary brokerage commissions and as a result of which 
not more than 10% of its total assets (determined at the time of investment) 
would be invested in such securities or except in connection with a merger, 
consolidation, reorganization or acquisition of assets. 
 
  (9) Invest for the purpose of exercising control or management of another 
company. 
 
  (10) Purchase industrial revenue bonds if, as a result of such purchase, more 
than 5% of total Fund assets would be invested in industrial revenue bonds 
where payment of principal and interest are the responsibility of companies 
with less than three years of operating history. 
 
  (11) Purchase or sell commodities or commodities futures contracts except 
financial futures contracts and options thereon. 
 
  (12) Invest more than 25% of the value of its total assets in securities 
whose issuers are located in any one state. 
 
  Whenever any fundamental investment policy or investment restriction states a 
maximum percentage of the Fund's assets, it is intended that if the percentage 
limitation is met at the time the investment is made, a later change in 
percentage resulting from changing total or net asset values will not be 
considered a violation of such policy. However, in the event that the Fund's 
asset coverage for borrowings falls below 300%, the Fund will take prompt 
action to reduce its borrowings, as required by applicable law.

  Pursuant to the Management Agreement with the Fund (the Management 
Agreement), PIFM, subject to the supervision of the Fund's Board of Directors 
and in conformity with the stated policies of the Fund, manages both the 
investment operations of the Fund and the composition of the Fund's portfolio, 
including the purchase, retention, disposition and loan of securities. In 
connection therewith, PIFM is obligated to keep certain books and records of 
the Fund. PIFM also administers the Fund's corporate affairs and, in connection 
therewith, furnishes the Fund with office facilities, together with those 
ordinary clerical and bookkeeping services which are not being furnished by 
State Street Bank and Trust Company, the Fund's Custodian, and Prudential 
Mutual Fund Services LLC (PMFS or the Transfer Agent), the Fund's transfer and 
dividend disbursing agent. The management services of PMF for the Fund are not 
exclusive under the terms of the Management Agreement and PIFM is free to, and 
does, render management services to others. 
 
  For its services, PIFM receives, pursuant to the Management Agreement, a fee

$250 million and .375 of 1% of the Fund's average daily net assets in excess of

Agreement also provides that, in the event the expenses of the Fund (including 
the fees of PIFM, but excluding interest, taxes, brokerage commissions, 
distribution fees and litigation and indemnification expenses and other 
extraordinary expenses not incurred in the ordinary course of the Fund's 
business) for any fiscal year exceed the lowest applicable annual expense 
limitation established and enforced pursuant to the statutes or regulations of 
any jurisdiction in which the Fund's shares are qualified for offer and sale, 
the compensation due to PIFM will be reduced by the amount of such excess. 
Reductions in excess of the total compensation payable to PIFM will be paid by 
PIFM to the Fund. No such reductions were required during the fiscal year ended 
December 31, 1997. No jurisdiction currently limits the Fund's expenses. 
 
  In connection with its management of the corporate affairs of the Fund, PIFM 
bears the following expenses: 
 
  (a) the salaries and expenses of all of its and the Fund's personnel except 
the fees and expenses of Directors who are not affiliated persons of PIFM or 
the Fund's investment adviser; 
 
  (b) all expenses incurred by PIFM or by the Fund in connection with managing 
the ordinary course of the Fund's business, other than those assumed by the 
Fund as described below; and 
 
  (c) the costs and expenses payable to The Prudential Investment Corporation, 
doing business as Prudential Investments (PI the Subadviser or the investment 
adviser), pursuant to the subadvisory agreement between PIFM and PI (the 
Subadvisory Agreement). 
 
  Under the terms of the Management Agreement, the Fund is responsible for the 
payment of the following expenses: (a) the fees payable to the Manager, (b) the 
fees and expenses of Directors who are not affiliated persons of the Manager or 
the Fund's investment adviser, (c) the fees and certain expenses of the 
Custodian and Transfer and Dividend Disbursing Agent, including the cost of 
providing records to the Manager in connection with its obligation of 
maintaining required records of the Fund and of pricing the Fund's shares, (d) 
the charges and expenses of legal counsel and independent accountants for the 
Fund, (e) brokerage commissions and any issue or transfer taxes chargeable to 
the Fund in connection with its securities transactions, (f) all taxes and 
corporate fees payable by the Fund to governmental agencies, (g) the fees of 
any trade associations of which the Fund may be a member, (h) the cost of stock 
certificates representing shares of the Fund, (i) the cost of fidelity and 
liability insurance, (j) the fees and expenses involved in registering and 
maintaining registration of the Fund and of its shares with the Commission, and 
paying the fees and expenses of notice filings made in accordance with state 
securities laws, including the preparation and printing of the Fund's 
registration statements and prospectuses for such purposes, (k) allocable 
communications expenses with respect to investor services and all expenses of 
shareholders' and Directors' meetings and of preparing, printing and mailing 
reports, proxy statements and prospectuses to shareholders in the amount 
necessary for distribution to the shareholders, (l) litigation and 
indemnification expenses and other extraordinary expenses not incurred in the 
ordinary course of the Fund's business and (m) distribution fees. 
 
  The Management Agreement provides that PIFM will not be liable for any error 
of judgment or for any loss suffered by the Fund in connection with the matters 
to which the Management Agreement relates, except a loss resulting from willful 
misfeasance, bad faith, gross negligence or reckless disregard of duty. The 
Management Agreement provides that it will terminate automatically if assigned, 
and that it may be terminated without penalty by either party upon not more 
than 60 days' nor less than 30 days' written notice. The Management Agreement 
will continue in effect for a period of more than two years from the date of 
execution only so long as such continuance is specifically approved at least 
annually in conformity with the Investment Company Act. The Management 
Agreement was last approved by the Board of Directors of the Fund, including a 
majority of the Directors who are not parties to the contract or interested 
persons of any such party as defined in the Investment Company Act on May 22, 
1997 and by shareholders of the Fund on April 28, 1988.

are provided to the Fund by a unit of the Subadviser, known as Prudential 
Mutual Fund Investment Management. 
 
  The Subadvisory Agreement was last approved by the Board of Directors, 
including a majority of the Directors who are not parties to such contracts or 
interested persons of such parties as defined in the Investment Company Act, on 
May 22, 1997, and by shareholders of the Fund on April 28, 1988. 
 
  The Subadvisory Agreement provides that it will terminate in the event of its 
assignment (as defined in the Investment Company Act) or upon the termination 
of the Management Agreement. The Subadvisory Agreement may be terminated by the 
Fund, PIFM or the Subadviser upon not more than 60 days', nor less than 30 
days', written notice. The Subadvisory Agreement provides that it will continue 
in effect for a period of more than two years from its execution only so long 
as such continuance is specifically approved at least annually in accordance 
with the requirements of the Investment Company Act. 
 
                                  DISTRIBUTOR
 
  Prudential Securities Incorporated (Prudential Securities or the 
Distributor), One Seaport Plaza, New York, New York 10292, acts as the 
distributor of the shares of the Fund. 
 
  Pursuant to 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), the Distributor incurs the 
expenses of distributing the Fund's Class A, Class B and Class C shares. See 
"How the Fund is Managed-Distributor" in the Prospectus. 
 
  Prior to January 22, 1990, the Fund offered only one class of shares (the 
then existing Class B shares). On October 6, 1989, the Board of Directors, 
including a majority of the Directors who are not interested persons of the 
Fund and who have no direct or indirect financial interest in the operation of 
the Class A or Class B Plan or in any agreement related to either Plan (the 
Rule 12b-1 Directors), at a meeting called for the purpose of voting on each 
Plan, adopted a new plan of distribution for the Class A shares of the Fund 
(the Class A Plan) and approved an amended and restated plan of distribution 
with respect to the Class B shares of the Fund (the Class B Plan). On February 
8, 1993, the Board of Directors, including a majority of the Rule 12b-1 
Directors, at a meeting called for the purpose of voting on each Plan, approved 
modifications to the Fund's Class A and Class B Plans and Distribution 
Agreements to conform them to recent amendments to the National Association of 
Securities Dealers, Inc. (NASD) maximum sales charge rule described below. As 
so modified, 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 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%. As so modified, the Class B Plan provides that (i) up to .25 of 1% of 
the average daily net assets of the Class B shares may be paid as a service fee 
and (ii) up to .50 of 1% (including the service fee) of the average daily net 
assets of the Class B shares (asset-based sales charge) may be used as 
reimbursement for distribution-related expenses with respect to the Class B 
shares. On May 3, 1993, the Board of Directors, including a majority of the 
Rule 12b-1 Directors, at a meeting called for the purpose of voting on each 
Plan, adopted a plan of distribution for the Class C shares of the Fund and 
approved further amendments to the plans of distribution for the Fund's Class A 
and Class B shares changing them from reimbursement type plans to compensation 
type plans. The Class C plan provides that (i) up to .25 of 1% of the average 
daily net assets of the Class C shares may be paid for providing personal 
service and/or maintaining shareholder accounts, and (ii) up to .75 of 1% of 
the average daily net assets of the Class C shares may be paid for 
distribution-related expenses with respect to the Class C shares. The Plans 
were last approved by the Board of Directors, including a majority of the Rule 
12b-1 Directors, on May 22, 1997. The Class A Plan, as amended, was approved by 
the Class A and Class B shareholders and the Class B Plan, as amended, was 
approved by Class B shareholders on July 19, 1994. The Class C Plan was 
approved by the sole shareholder of Class C shares on August 1, 1994.

  Class A Plan. For the fiscal year ended December 31, 1997, the Distributor 
received $491,279 under the Class A Plan. This amount was primarily expended on 
commission credits to the Distributor and Prusec for payment of account 
servicing fees to financial advisers and other persons who sell Class A shares. 
For the fiscal year ended December 31, 1997, the Distributor also received 
approximately $52,100 in initial sales charges. 
 
  Class B Plan. For the fiscal year ended December 31, 1997, the Distributor 
received $759,692 from the Fund under the Class B Plan. It is estimated that 
the Distributor spent approximately $456,200 in distributing the Fund's Class B 
shares, on behalf of the Fund during the year ended December 31, 1997. It is 
estimated that of this amount approximately $6,600 (1.5%) was spent on printing 
and mailing of prospectuses to other than current shareholders; $112,200 
(24.6%) on compensation to Prusec, an affiliated broker-dealer, for commissions 
to its representatives and other expenses, including an allocation of overhead 
and other branch office distribution-related expenses, incurred by it for 
distribution of Fund shares; and $337,400 (73.9%) on the aggregate of (i) 
payments of commissions to financial advisers ($246,400 or 54.0%) and (ii) an 
allocation on account of overhead and other branch office distribution-related 
expenses ($91,000 or 19.9%). The term "overhead and other branch office 
distribution-related expenses" represents (a) the expenses of operating the 
Distributor's branch offices in connection with the sale of Fund shares, 
including lease costs, the salaries and employee benefits of operations and 
sales support personnel, utility costs, communications costs and the costs of 
stationery and supplies, (b) the costs of client sales seminars, (c) expenses 
of mutual fund sales coordinators to promote the sale of Fund shares and (d) 
other incidental expenses relating to branch promotion of Fund sales. 
 
  The Distributor also receives the proceeds of contingent deferred sales 
charges paid by holders of Class B shares upon certain redemptions of Class B 
shares. See "Shareholder Guide-How to Sell Your Shares-Contingent Deferred 
Sales Charge " in the Prospectus. For the fiscal year ended December 31, 1997, 
the Distributor received approximately $393,600 in contingent deferred sales 
charges with respect to Class B shares. 
 
  Class C Plan. For the fiscal year ended December 31, 1997 the Distributor 
received $5,686 under the Class C Plan and spent approximately $5,000 in 
distributing Class C shares. The Distributor also receives the proceeds of 
contingent deferred sales charges paid by investors upon certain redemptions of 
Class C shares. See "Shareholder Guide-How to Sell Your Shares-Contingent 
Deferred Sales Charges" in the Prospectus. For the fiscal year ended December 
31, 1997, the Distributor received approximately $3,900 in contingent deferred 
sales charges with respect to Class C shares. 
 
  The Class A, Class B and Class C Plans continue in effect from year to year, 
provided that each such continuance is approved at least annually by a vote of 
the Board of Directors, including a majority vote of the Rule 12b-1 Directors, 
cast in person at a meeting called for the purpose of voting on such 
continuance. The Plans may each be terminated at any time, without penalty, by 
the vote of a majority of the Rule 12b-1 Directors or by the vote of the 
holders of a majority of the outstanding shares of the applicable class on not 
more than 60 days' written notice to any other party to the Plans. None of the 
Plans may be amended to increase materially the amounts to be spent for the 
services described therein without approval by the shareholders of the 
applicable class (by both Class A and Class B shareholders, voting separately, 
in the case of material amendments to the Class A Plan), and all material 
amendments are required to be approved by the Board of Directors in the manner 
described above. Each Plan will automatically terminate in the event of its 
assignment. The Fund will not be contractually obligated to pay expenses 
incurred under any Plan if it is terminated or not continued. 
 
  Pursuant to each Plan, the Board of Directors will review at least quarterly 
a written report of the distribution expenses incurred on behalf of each class 
of shares of the Fund by the Distributor. The report will include an 
itemization of the distribution expenses and the purposes of such expenditures. 
In addition, as long as the Plans remain in effect, the selection and 
nomination of the Rule 12b-1 Directors shall be committed to the Rule 12b-1 
Directors. 
 
  Pursuant to the Distribution Agreement, the Fund has agreed to indemnify the 
Distributor to the extent permitted by applicable law against certain 
liabilities under federal securities law. A restated Distribution Agreement was 
last approved by the Board of Directors, including a majority of the Rule 12b-1 
Directors, on May 22, 1997. 
 
  NASD Maximum Sales Charge Rule. Pursuant to rules of the NASD, the 
Distributor is required to limit aggregate initial sales charges, deferred 
sales charges and asset-based sales charges to 6.25% of total gross sales of 
each class of shares. Interest charges on unreimbursed distribution expenses 
equal to the prime rate plus one percent per annum may be added to the 6.25% 
limitation. Sales from the reinvestment of dividends and distributions are not 
included in the calculation of the 6.25% limitation. The annual asset-based 
sales charge on shares of the Fund may not exceed .75 of 1% per class. The 
6.25% limitation applies to the Fund rather than on a per shareholder basis. If 
aggregate sales charges were to exceed 6.25% of total gross sales of any class, 
all sales charges on shares of that class would be suspended.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE
 
  The Manager is responsible for decisions to buy and sell securities and 
futures contracts for the Fund, the selection of brokers, dealers and futures 
commission merchants to effect the transactions and the negotiation of 
brokerage commissions, if any. The term "Manager" as used in this section 
includes the "Subadviser." Fixed-income securities are generally traded on a 
"net" basis with dealers acting as principal for their own accounts without a 
stated commission, although the price of the security usually includes a profit 
to the dealer. In underwritten offerings, securities are purchased at a fixed 
price which includes an amount of compensation to the underwriter, generally 
referred to as the underwriter's concession or discount. The Fund will not deal 
with Prudential Securities in any transaction in which Prudential Securities 
acts as principal. Purchases and sales of securities on a securities exchange, 
while infrequent, and purchases and sales of futures on a commodities exchange 
or board of trade will be effected through brokers who charge a commission for 
their services. Orders may be directed to any broker including, to the extent 
and in the manner permitted by applicable law, Prudential Securities and its 
affiliates. 
 
  In placing orders for portfolio securities of the Fund, the Manager is 
required to give primary consideration to obtaining the most favorable price 
and efficient execution. This means that the Manager will seek to execute each 
transaction at a price and commission, if any, which provide the most favorable 
total cost or proceeds reasonably attainable in the circumstances. While the 
Manager generally seeks reasonably competitive spreads or commissions, the Fund 
will not necessarily be paying the lowest spread or commission available. 
Within the framework of the policy of obtaining most favorable price and 
efficient execution, the Manager will consider research and investment services 
provided by brokers or dealers who effect or are parties to portfolio 
transactions of the Fund, the Manager or the Manager's other clients. Such 
research and investment services are those which brokerage houses customarily 
provide to institutional investors and include statistical and economic data 
and research reports on particular companies and industries. Such services are 
used by the Manager in connection with all of its investment activities, and 
some of such services obtained in connection with the execution of transactions 
for the Fund may be used in managing other investment accounts. Conversely, 
brokers furnishing such services may be selected for the execution of 
transactions of such other accounts, whose aggregate assets are larger than the 
Fund, and the services furnished by such brokers may be used by the Manager in 
providing investment management for the Fund. Commission rates are established 
pursuant to negotiations with the broker based on the quality and quantity of 
execution services provided by the broker in light of generally prevailing 
rates. The Manager's policy is to pay higher commissions to brokers, other than 
Prudential Securities, for particular transactions than might be charged if a 
different broker had been selected, on occasions when, in the Manager's 
opinion, this policy furthers the objective of obtaining best price and 
execution. In addition, the Manager is authorized to pay higher commissions on 
brokerage transactions for the Fund to brokers other than Prudential Securities 
in order to secure research and investment services described above, subject to 
the primary consideration of obtaining the most favorable price and efficient 
execution in the circumstances and subject to review by the Fund's Board of 
Directors from time to time as to the extent and continuation of this practice. 
The allocation of orders among brokers and the commission rates paid are 
reviewed periodically by the Board of Directors. Portfolio securities may not 
be purchased from any underwriting or selling syndicate of which Prudential 
Securities (or any affiliate), during the existence of the syndicate, is a 
principal underwriter (as defined in the Investment Company Act), except in 
accordance with rules of the Commission. This limitation, in the opinion of the 
Fund, will not significantly affect the Fund's ability to pursue its present 
investment objective. However, in the future in other circumstances, the Fund 
may be at a disadvantage because of this limitation in comparison to other 
funds with similar objectives but not subject to such limitations. 
 
  Subject to the above considerations, the Manager may use Prudential 
Securities as a broker or futures commission merchant for the Fund. In order 
for Prudential Securities (or any affiliate) to effect any portfolio 
transactions for the Fund on an exchange or board of trade, the commissions, 
fees or other remuneration received by Prudential Securities (or any affiliate) 
must be reasonable and fair compared to the commissions, fees or other 
remuneration paid to other brokers or futures commission merchants in 
connection with comparable transactions involving similar securities or futures 
contracts being purchased or sold on a securities exchange or board of trade 
during a comparable period of time. This standard would allow Prudential 
Securities (or any affiliate) to receive no more than the remuneration which 
would be expected to be received by an unaffiliated broker or futures 
commission merchant in a commensurate arm's-length transaction. Furthermore, 
the Board of Directors of the Fund, including a majority of the noninterested 
Directors has adopted procedures which are reasonably designed to provide that 
any commissions, fees or other remuneration paid to Prudential Securities (or 
any affiliate) are consistent with the foregoing standard. In accordance with 
Section 11(a) of the Securities Exchange Act of 1934, as amended, Prudential 
Securities may not retain compensation for effecting transactions on a national 
securities exchange for the Fund unless the Fund has expressly authorized the 
retention of such compensation. Prudential Securities must furnish to the Fund 
at least annually a statement setting forth the total amount of all 
compensation retained by Prudential Securities from transactions effected for 
the Fund during the applicable period. Brokerage transactions with Prudential 
Securities (or any affiliate) are also subject to such fiduciary standards as 
may be imposed upon Prudential Securities (or such affiliate) by applicable 
law.

  The Fund paid no brokerage commissions to Prudential Securities for the 
fiscal years ended December 31, 1994, 1995 and 1996. 
 
                     PURCHASE AND REDEMPTION OF FUND SHARES
 
  Shares of the Fund may be purchased at a price equal to the next determined 
net asset value (NAV) per share plus a sales charge which, at the election of 
the investor, may be imposed either (i) at the time of purchase (Class A 
shares) or (ii) on a deferred basis (Class B or Class C shares). See 
"Shareholder Guide" in the Prospectus. 
 
  Each class of shares 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, which may affect 
performance, (ii) each class has exclusive voting rights with respect to any 
matter submitted to shareholders that relates solely to its arrangement and has 
separate voting rights on any matter submitted to shareholders in which the 
interests of one class differ from the interests of any other class (except 
that the Fund has agreed with the Commission in connection with the offering of 
a conversion feature on Class B shares to submit any amendment of the Class A 
distribution and service plan to both Class A and Class B shareholders), and 
(iii) each class has a different exchange privilege and (iv) only Class B 
shares have a conversion feature. See "Distributor" and "Shareholder Investment 
Account-Exchange Privilege." 
 
Issuance of Fund Shares for Securities
 
  Transactions involving the issuance of Fund shares for securities (rather 
than cash) will be limited to (i) reorganizations, (ii) statutory mergers, or 
(iii) other acquisitions of portfolio securities that: (a) meet the investment 
objective and policies of the Fund, (b) are liquid and not subject to 
restrictions on resale, and (c) have a value that is readily ascertainable via 
listing on or trading in a recognized United States or international exchange 
market, and (d) are approved by the Fund's investment advisor. 
 
Specimen Price Make-up
 
  Under the current distribution arrangements between the Fund and the 
Distributor, Class A shares of the Fund are sold at a maximum sales charge of 
3% and Class B*, and Class C* shares of the Fund are sold at NAV. Using the 
Fund's NAV at December 31, 1997, the maximum offering price of the Fund's 
shares is as follows:

on certain redemptions. See "Shareholder Guide-How to Sell Your

Reduction and Waiver of Initial Sales Charges-Class A Shares
 
  Combined Purchase and Cumulative Purchase Privilege. If an investor or 
eligible group of related investors purchases Class A shares of the Fund 
concurrently with Class A shares of other Prudential Mutual Funds, the 
purchases may be combined to take advantage of the reduced sales charges 
applicable to larger purchases. See the table of breakpoints under "Shareholder 
Guide-Alternative Purchase Plan" in the Prospectus. 
 
  An eligible group of related Fund investors includes any combination of the 
following: 
 
  (a) an individual;
 
  (b) the individual's spouse, their children and their parents;
 
  (c) the individual's and spouse's Individual Retirement Account (IRA);
 
  (d) any company controlled by the individual (a person, entity or group that 
      holds 25% or more of the outstanding voting securities of a company will 
      be deemed to control the company, and a partnership will be deemed to be 
      controlled by each of its general partners); 
                                      B-15
 
<PAGE> 
 
  (e) a trust created by the individual, the beneficiaries of which are the 
individual, his or her spouse, parents or children; 
 
  (f) a Uniform Gifts to Minors Act/Uniform Transfers to Minors Act account 
      created by the individual or the individual's spouse; and 
 
  (g) one or more employee benefit plans of a company controlled by an 
individual. 
 
  An eligible group of related Fund investors may include an employer (or group 
of related employers) and one or more qualified retirement plans of such 
employer or employers (an employer controlling, controlled by or under common 
control with another employer is deemed related to that employer). 
 
  In addition, an eligible group of related Fund investors may include (i) a 
client of a Prudential Securities financial adviser who gives such financial 
adviser discretion to purchase the Prudential Mutual Funds for his or her 
account only in connection with participation in a market timing program and 
for which program Prudential Securities receives a separate advisory fee or 
(ii) a client of an unaffiliated registered investment adviser which is a 
client of a Prudential Securities financial adviser, if such unaffiliated 
adviser has discretion to purchase the Prudential Mutual Funds for the accounts 
of his or her customers but only if the client of such unaffiliated adviser 
participates in a market timing program conducted by such unaffiliated adviser; 
provided such accounts in the aggregate have assets of at least $15 million 
invested in the Prudential Mutual Funds. 
 
 
  The Distributor must be notified at the time of purchase that the investor is 
entitled to a reduced sales charge. The reduced sales charges will be granted 
subject to confirmation of the investor's holdings. The Combined Purchase and 
Cumulative Purchase Privilege does not apply to individual participants in any 
retirement or group plans. 
 
  Rights of Accumulation. Reduced sales charges are also available through 
Rights of Accumulation, under which an investor or an eligible group of related 
investors, as described above under "Combined Purchase and Cumulative Purchase 
Privilege," may aggregate the value of their existing holdings of the Class A 
shares of the Fund and Class A shares of other Prudential Mutual Funds 
(excluding money market funds other than those acquired pursuant to the 
exchange privilege) to determine the reduced sales charge. However, the value 
of shares held directly with the Transfer Agent and through Prudential 
Securities will not be aggregated to determine the reduced sales charge. All 
shares must be held either directly with the Transfer Agent or through 
Prudential Securities. The value of existing holdings for purposes of 
determining the reduced sales charge is calculated using the maximum offering 
price (NAV plus maximum sales charge) as of the previous business day. See "How 
the Fund Values its Shares" in the Prospectus. The Distributor must be notified 
at the time of purchase that the investor is entitled to a reduced sales 
charge. The reduced sales charges will be granted subject to confirmation of 
the investor's holdings. Rights of Accumulation are not available to individual 
participants in any retirement or group plans. 
 
  Letters of Intent. Reduced sales charges are also available to investors (or 
an eligible group of related investors) who enter into a written Letter of 
Intent providing for the purchase, within a thirteen-month period, of shares of 
the Fund and shares of other Prudential Mutual Funds. All shares of the Fund 
and shares of other Prudential Mutual Funds (excluding money market funds other 
than those acquired pursuant to the exchange privilege) which were previously 
purchased and are still owned are also included in determining the applicable 
reduction. However, the value of shares held directly with the Transfer Agent 
and through Prudential Securities will not be aggregated to determine the 
reduced sales charge. All shares must be held either directly with the Transfer 
Agent or through Prudential Securities. The Distributor must be notified at the 
time of purchase that the investor is entitled to a reduced sales charge. The 
reduced sales charges will be granted subject to confirmation of the investor's 
holdings. Letters of Intent are not available to individual participants in any 
retirement or group plans. 
 
  A Letter of Intent permits a purchaser to establish a total investment goal 
to be achieved by any number of investments over a thirteen-month period. Each 
investment made during the period will receive the reduced sales charge 
applicable to the amount represented by the goal, as if it were a single 
investment. Escrowed Class A shares totaling 5% of the dollar amount of the 
Letter of Intent will be held by the Transfer Agent in the name of the 
purchaser. The effective date of a Letter of Intent may be back-dated up to 90 
days, in order that any investments made during this 90-day period, valued at 
the purchaser's cost, can be applied to the fulfillment of the Letter of Intent 
goal. 
 
  The Letter of Intent does not obligate the investor to purchase, nor the Fund 
to sell, the indicated amount. In the event the Letter of Intent goal is not 
achieved within the thirteen-month period, the purchaser is required to pay the 
difference between the sales charge otherwise applicable to the purchases made 
during this period and sales charges actually paid. Such payment may be made 
directly to the Distributor or, if not paid, the Distributor will liquidate 
sufficient escrowed shares to obtain such difference. Investors electing to 
purchase Class A shares of the Fund pursuant to a Letter of Intent should 
carefully read such Letter of Intent.

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

  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 the reduced CDSC. The reduced CDSC will be granted subject to 
confirmation of your holdings. 
 
                         SHAREHOLDER INVESTMENT ACCOUNT
 
  Upon the initial purchase of Fund shares, a Shareholder Investment Account is 
established for each investor under which a record of the shares held is 
maintained by the Transfer Agent. If a share certificate is desired, it must be 
requested in writing for each transaction. Certificates are issued only for 
full shares and may be redeposited in the Account at any time. There is no 
charge to the investor for issuance of a certificate. The Fund makes available 
to the shareholders the following privileges and plans. 
 
Automatic Reinvestment of Dividends and/or Distributions
 
  For the convenience of investors, all dividends and distributions are 
automatically reinvested in full and fractional shares of the Fund at net asset 
value per share. An investor may direct the Transfer Agent in writing not less 
than five full business days prior to the record date to have subsequent 
dividends and/or distributions sent to him or her in cash rather than 
reinvested. In the case of recently purchased shares for which registration 
instructions have not been received on the record date, cash payment will be 
made directly to the dealer. Any shareholder who receives a cash payment 
representing a dividend or distribution may reinvest such distribution at NAV 
by returning the check or the proceeds to the Transfer Agent within 30 days 
after the payment date. Such investment will be made at the NAV per share next 
determined after receipt of the check or proceeds by the Transfer Agent. Such 
shareholder will receive credit for any CDSC paid in connection with the amount 
of proceeds being reinvested.

Exchange Privilege
 
  The Fund makes available to its shareholders the privilege of exchanging 
their shares of the Fund for shares of certain other Prudential Mutual Funds, 
including one or more specified money market funds, subject in each case to the 
minimum investment requirements of such funds. Shares of such other Prudential 
Mutual Funds may also be exchanged for shares, respectively, of the Fund. All 
exchanges are made on the basis of the relative NAV next determined after 
receipt of an order in proper form. An exchange will be treated as a redemption 
and purchase for tax purposes. Shares may be exchanged for shares of another 
fund only if shares of such fund may legally be sold under applicable state 
laws. 
 
  It is contemplated that the exchange privilege may be applicable to new 
mutual funds whose shares may be distributed by the Distributor. 
 
  Class A. Shareholders of the Fund may exchange their Class A shares for Class 
A shares of certain other Prudential Mutual Funds, shares of Prudential 
Structured Maturity Fund and Prudential Government Securities Trust 
(Short-Intermediate Term Series) and shares of the money market funds specified 
below. No fee or sales load will be imposed upon the exchange. Shareholders of 
money market funds who acquired such shares upon exchange of Class A shares may 
use the Exchange Privilege only to acquire Class A shares of the Prudential 
Mutual Funds participating in the Exchange Privilege. 
 
  The following money market funds participate in the Class A Exchange 
Privilege: 
 
Prudential California Municipal Fund
(California Money Market Series)
 
Prudential Government Securities Trust
(Money Market Series) (Class A shares)
(U.S. Treasury Money Market Series) (Class A shares)
 
Prudential Municipal Series Fund
(Connecticut Money Market Series)
(Massachusetts Money Market Series)
(New Jersey Money Market Series)
(New York Money Market Series)
 
Prudential MoneyMart Assets, Inc. (Class A shares)
 
Prudential Tax-Free Money Fund, Inc.
 
  Class B and Class C. Shareholders of the Fund may exchange their Class B and 
Class C shares for Class B and Class C shares, respectively, of certain other 
Prudential Mutual Funds and shares of Prudential Special Money Market Fund. No 
CDSC will be payable upon such exchange of Class B and Class C shares, but a 
CDSC will be payable upon the redemption of Class B shares acquired as a result 
of the exchange. The applicable sales charge will be that imposed by the fund 
in which shares were initially purchased and the purchase date will be deemed 
to be the first day of the month after the initial purchase, rather than the 
date of the exchange. 
 
  Class B and Class C shares of the Fund may also be exchanged for shares of 
Prudential Special Money Market Fund without imposition of any CDSC at the time 
of exchange. Upon subsequent redemption from such money market fund or after 
re-exchange into the Fund, such shares may be subject to the CDSC calculated by 
excluding the time such shares were held in the money market fund. In order to 
minimize the period of time in which shares are subject to a CDSC, shares 
exchanged out of the money market fund will be exchanged on the basis of their 
remaining holding periods, with the longest remaining holding periods being 
transferred first. In measuring the time period shares are held in a money 
market fund and "tolled" for purposes of calculating the CDSC holding period, 
exchanges are deemed to have been made on the last day of the month. Thus, if 
shares are exchanged into the Fund from a money market fund during the month 
(and are held in the Fund at the end of the month), the entire month will be 
included in the CDSC holding period. Conversely, if shares are exchanged into a 
money market fund prior to the last day of the month (and are held in the money 
market fund on the last day of the month), the entire month will be excluded 
from the CDSC holding period. For purposes of calculating the seven year 
holding period applicable to the Class B conversion feature, the time period 
during which Class B shares were held in a money market account will be 
excluded. 
 
  At any time after acquiring shares of other funds participating in the Class 
B or Class C exchange privilege the shareholder may again exchange those shares 
(and any reinvested dividends and distributions) for Class B or Class C shares 
of the Fund without subjecting such shares to any CDSC. Shares of any fund 
participating in the Class B or Class C exchange privilege that were acquired 
through reinvestment of dividends or distributions may be exchanged for Class B 
or Class C shares of other funds, respectively, without being subject to any 
CDSC.

<PAGE> 
 
  Additional details about the Exchange Privilege and prospectuses for each of 
the Prudential Mutual Funds are available from the Transfer Agent, Prudential 
Securities or Prusec. The Exchange Privilege may be modified, terminated or 
suspended on sixty days' notice, and any fund, including the Fund, or the 
Distributor, has the right to reject any exchange application relating to such 
fund's shares. 
 
Dollar Cost Averaging
 
  Dollar cost averaging is a method of accumulating shares by investing a fixed 
amount of dollars in shares at set intervals. An investor buys more shares when 
the price is low and fewer shares when the price is high. The average cost per 
share is lower than it would be if a constant number of shares were bought at 
set intervals. 
 
  Dollar cost averaging may be used, for example, to plan for retirement, to 
save for a major expenditure, such as the purchase of a home, or to finance a 
college education. The cost of a year's education at a four-year college today 
averages around $14,000 at a private college and around $6,000 at a public 
university. Assuming these costs increase at a rate of 7% a year, as has been 
projected, for the freshman class of 2011, the cost of four years at a private 
college could reach $210,000 and over $90,000 at a public university.1 
 
  The following chart shows how much you would need in monthly investments to 
achieve specified lump sums to finance your investment goals2.

  1Source information concerning the costs of education at public and private 
          universities is available from The College Board Annual Survey of 
          Colleges, 1993. Average costs for private institutions include 
          tuition, fees, room and board. 
  2The chart assumes an effective rate of return of 8% (assuming monthly 
       compounding). This example is for illustrative purposes only and is not 
       intended to reflect the performance of an investment in shares of the 
       Fund. The investment return and principal value of an investment will 
       fluctuate so that an investor's shares when redeemed may be worth more 
       or less than their original cost.  
 
Automatic Savings Accumulation Plan (ASAP)
 
  Under ASAP, an investor may arrange to have a fixed amount automatically 
invested in shares of the Fund monthly by authorizing his or her bank account 
or Prudential Securities account (including a Command Account) to be debited to 
invest specified dollar amounts in shares of the Fund. The investor's bank must 
be a member of the Automatic Clearing House System. Share certificates are not 
issued to ASAP participants. 
 
  Further information about this program and an application form can be 
obtained from the Transfer Agent, Prudential Securities or Prusec. 
 
Systematic Withdrawal Plan
 
  A systematic withdrawal plan is available to shareholders having shares of 
the Fund held through Prudential Securities or the Transfer Agent. Such 
withdrawal plan provides for monthly or quarterly checks in any amount, except 
as provided below, up to the value of the shares in the shareholder's account. 
Withdrawals of Class B or Class C shares may be subject to a CDSC. See 
"Shareholder Guide-How to Sell Your Shares-Contingent Deferred Sales Charges" 
in the Prospectus. 
 
  In the case of shares held through the Transfer Agent (i) a $10,000 minimum 
account value applies, (ii) withdrawals may not be for less than $100 and (iii) 
the shareholder must elect to have all dividends and/or distributions 
automatically reinvested in additional full and fractional shares at net asset 
value on shares held under this plan. See "Shareholder Investment 
Account-Automatic Reinvestment of Dividends and/or Distributions." 
 
                                      B-19
 
<PAGE> 

  Prudential Securities and the Transfer Agent act as agents for the 
shareholder in redeeming sufficient full and fractional shares to provide the 
amount of the periodic withdrawal payment. The systematic withdrawal plan may 
be terminated at any time, and the Distributor reserves the right to initiate a 
fee of up to $5 per withdrawal, upon 30 days' written notice to the 
shareholder. 
 
  Withdrawal payments should not be considered as dividends, yield, or income. 
If periodic withdrawals continuously exceed reinvested dividends and 
distributions, the shareholder's original investment will be correspondingly 
reduced and ultimately exhausted. 
 
  Furthermore, each withdrawal constitutes a redemption of shares, and any gain 
or loss realized generally must be recognized for federal income tax purposes. 
In addition, withdrawals made concurrently with purchases of additional shares 
are inadvisable because of the sales charge applicable to (i) the purchase of 
Class A shares and (ii) the withdrawal of Class B and Class C shares. Each 
shareholder should consult his or her own tax adviser with regard to the tax 
consequences of the systematic withdrawal plan. 
 
Mutual Fund Programs
 
  From time to time, the Fund may be included in a mutual fund program with 
other Prudential Mutual Funds. Under such a program, a group of portfolios will 
be selected and thereafter marketed collectively. Typically, these programs are 
created with an investment theme, e.g., to seek greater diversification, 
protection from interest rate movements or access to different management 
styles. In the event such a program is instituted, there may be a minimum 
investment requirement for the program as a whole. The Fund may waive or reduce 
the minimum initial investment requirements in connection with such a program. 
 
  The mutual funds in the program may be purchased individually or as part of 
the program. Since the allocation of portfolios included in the program may not 
be appropriate for all investors, individuals should consult their Prudential 
Securities Financial Advisor or Prudential/Pruco Securities Representative 
concerning the appropriate blend of portfolios for them. If investors elect to 
purchase the individual mutual funds that constitute the program in an 
investment ratio different from that offered by the program, the standard 
minimum investment requirements for the individual mutual funds will apply. 
 
                                NET ASSET VALUE
 
  The net asset value (NAV) per share is the net worth of the Fund (assets, 
including securities at value, minus liabilities) divided by the number of 
shares outstanding. NAV is calculated separately for each class. The Fund will 
compute its NAV once daily at 4:15 P.M., New York time, on each day the New 
York Stock Exchange is open for trading except on days on which no orders to 
purchase, sell or redeem Fund shares have been received or days on which 
changes in the value of the Fund's portfolio securities do not affect the NAV. 
The New York Stock Exchange is closed on the following holidays: New Year's 
Day, Washington's Birthday, Good Friday, Memorial Day, Independence Day, Labor 
Day, Thanksgiving Day and Christmas Day. In the event the New York Stock 
Exchange closes early on any business day, the NAV of the Fund's shares shall 
be determined at a time between such closing and 4:15 P.M., New York time. The 
New York Stock Exchange is closed on the following holidays: New Years Day, 
Martin Luther King, Jr. Day, Presidents Day, Good Friday, Memorial Day, 
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. 
 
  Portfolio securities for which reliable market quotations are readily 
available or for which the pricing agent or principal market maker does not 
provide a valuation or methodology or provides a valuation or methodology that, 
in the judgment of the Manager or Subadvisor, are valued by the Valuation 
Committee or Board of Directors in coordination with the Manager or Subadvisor. 
When market quotations are not readily available, such securities and other 
assets are valued at fair value in accordance with procedures adopted by the 
Board of Directors. Under these procedures, the Fund values municipal 
securities on the basis of valuations provided by a pricing service which uses 
information with respect to transactions in bonds, quotations from bond 
dealers, market transactions in comparable securities and various relationships 
between securities in determining value. This service is expected to be 
furnished by J. J. Kenny Information Systems Inc. Short-term securities 
maturing within 60 days of the valuation date are valued at amortized cost, if 
their original maturity was 60 days or less, or by amortizing their value on 
the 61st day prior to maturity, if their original term to maturity exceeded 60 
days, unless such valuation is determined not to represent fair value by the 
Board of Directors. 
 
  NAV is calculated separately for each class. The NAV of Class B and Class C 
shares will generally be lower than the NAV of Class A shares as a result of 
the larger distribution-related fee to which Class B and Class C shares are 
subject. It is expected, that the NAV 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.

                       TAXES, DIVIDENDS AND DISTRIBUTIONS
 
  The Fund will declare a dividend immediately prior to 4:15 P.M. on each day 
that net asset value per share of the Fund is determined of all of the daily 
net income of the Fund to shareholders of record of the Fund as of 4:15 P.M., 
New York time, of the preceding business day. The amount of the dividend may 
fluctuate from day to day. Unless otherwise requested by the shareholder, 
dividends are automatically reinvested monthly in additional full or fractional 
shares of the Fund at net asset value per share. The dividend payment date is 
on or about the 25th day of each month, although the Fund reserves the right to 
change this date without further notice to shareholders. Shareholders may 
receive cash payments from the Fund equal to the dividends earned during the 
month by completing the appropriate section on the Application Form or by 
notifying Prudential Mutual Fund Services LLC (PMFS), the Fund's Transfer and 
Dividend Disbursing Agent, at least five business days prior to the payable 
date. Cash distributions are paid by check within five business days after the 
dividend payment date. 
 
  The Fund intends to distribute to shareholders of record monthly dividends 
consisting of all of the net investment income of the Fund. Net capital gains 
of the Fund will be distributed at least annually. 
 
  The per share dividends on Class B and Class C shares will be lower than the 
per share dividends on Class A shares as a result of the higher 
distribution-related fee to which Class B and Class C shares are subject. The 
per share distributions of net capital gains, if any, will be paid in the same 
amount for Class A, Class B and Class C shares. See "Net Asset Value." 
 
  The Fund is qualified and intends to remain qualified as a regulated 
investment company under Subchapter M of the Internal Revenue Code of 1986, as 
amended (Internal Revenue Code). Under the Internal Revenue Code, the Fund is 
not subject to federal income taxes on the taxable income that it distributes 
to shareholders, provided that at least 90% of its net taxable investment 
income and net short-term capital gains in excess of net long-term capital 
losses and 90% of its net tax-exempt interest income in each taxable year is so 
distributed. Qualification as a regulated investment company under the Internal 
Revenue Code requires, among other things, that the Fund (a) derive at least 
90% of its annual gross income (without offset for losses from the sale or 
other disposition of securities or foreign currencies) from dividends, 
interest, payments with respect to securities loans and gains from the sale or 
other disposition of securities or foreign currencies and certain financial 
futures, options and forward contracts; (b) derive less than 30% of its gross 
income from gains from the sale or other disposition of securities or options 
thereon held for less than three months; and (c) diversify its holdings so 
that, at the end of each quarter of the taxable year, (i) at least 50% of the 
market value of the Fund's assets is represented by cash, U.S. Government 
securities and other securities limited in respect of any one issuer to an 
amount not greater than 5% of the market value of the Fund's assets and 10% of 
the outstanding voting securities of such issuer, and (ii) not more than 25% of 
the value of its assets is invested in the securities of any one issuer (other 
than U.S. Government securities). The Fund intends to comply with the 
provisions of the Internal Revenue Code that require at least 50% of the value 
of its total assets at the close of each quarter of its taxable year to consist 
of obligations the interest on which is exempt from federal income tax in order 
to pass through tax-exempt income to its shareholders. 
 
  The Fund generally will be subject to a nondeductible excise tax of 4% to the 
extent that it does not meet certain minimum distribution requirements as of 
the end of each calendar year. The Fund intends to make timely distributions of 
the Fund's income in compliance with these requirements. As a result, it is 
anticipated that the Fund will not be subject to the excise tax. 
 
  Gains or losses on sales of securities by the Fund will be treated as capital 
gains or losses the character of which will depend upon the Fund's holding 
period in the securities. The acquisition of a put by the Fund may affect the 
holding period of securities held by the Fund. Certain financial futures 
contracts held by the Fund will be required to be "marked to market" for 
federal income tax purposes, that is, treated as having been sold at their fair 
market value on the last day of the Fund's taxable year. Any gain or loss 
recognized on actual or deemed sales of these financial futures contracts will 
be treated as 60% long-term capital gain or loss and 40% short-term capital 
gain or loss. The Fund may be required to defer the recognition of losses on 
financial futures contracts to the extent of any unrecognized gains on related 
positions held by the Fund. 
 
  The Fund's gains and losses on the sale, lapse, or other termination of call 
options it holds on financial futures contracts will generally be treated as 
gains and losses from the sale of financial futures contracts. If call options 
written by the Fund expire unexercised, the premiums received by the Fund give 
rise to short-term capital gains at the time of expiration. The Fund may also 
have short-term gains and losses associated with closing transactions with 
respect to call options written by the Fund. If call options written by the 
Fund are exercised, the selling price of the financial futures contract is 
increased by the amount of the premium received by the Fund, and the character 
of the capital gain or loss on the sale of the futures contract depending on 
the contract's holding period. 
 
                                      B-21
 
<PAGE> 

  Upon the exercise of a put held by the Fund, the premium initially paid for 
the put is offset against the amount received for the futures contract, bond or 
note sold pursuant to the put thereby decreasing any gain (or increasing any 
loss) realized on the sale. Generally, such gain or loss is capital gain or 
loss, the character of which depends on the holding period of the futures 
contract, bond or note. However, in certain cases in which the put is not 
acquired on the same day as the underlying securities identified to be used in 
the put's exercise, gain on the exercise, sale or disposition of the put is 
short-term capital gain. If a put is sold prior to exercise, any gain or loss 
recognized by the Fund would be capital gain or loss, depending on the holding 
period of the put. If a put expires unexercised, the Fund would realize 
short-term or long-term capital loss, the character of which depends on the 
holding period of the put, in an amount equal to the premium paid for the put. 
In certain cases in which the put and securities identified to be used in its 
exercise are acquired on the same day, however, the premium paid for the 
unexercised put is added to the basis of the identified securities. 
 
  Interest on indebtedness incurred or continued by a shareholder, whether a 
corporation or an individual, to purchase or carry shares of the Fund is not 
deductible to the extent that distributions from the Fund are exempt from 
Federal income tax. The Treasury has the authority to issue regulations which 
would disallow the interest deduction if incurred to purchase or carry shares 
of the Fund owned by the taxpayer's spouse, minor child or an entity controlled 
by the taxpayer. Shareholders who have held their shares for six months or less 
may be subject to a disallowance of losses from the sale or exchange of those 
shares to the extent of any dividends received by the shareholders on such 
shares and, if such losses are not disallowed, they will be treated as 
long-term capital losses to the extent of any distribution of long-term capital 
gains received by the shareholders with respect to such shares. Entities or 
persons who are "substantial users" (or related persons) of facilities financed 
by private activity bonds should consult their tax advisers before purchasing 
shares of the Fund. 
 
  Any loss realized on a sale, redemption or exchange of shares of the Fund by 
a shareholder will be disallowed to the extent the shares are replaced within a 
61-day period (beginning 30 days before the disposition of shares). Shares 
purchased pursuant to the reinvestment of a dividend will constitute a 
replacement of shares. In such a case, the basis of the shares acquired will be 
adjusted to reflect the disallowed loss. 
 
  A shareholder who acquires shares of the Fund and sells or otherwise disposes 
of such shares within 90 days of acquisition may not be allowed to include 
certain sales charges incurred in acquiring such shares for purposes of 
calculating gain or loss realized upon a sale or exchange of shares of the 
Fund. 
 
  Exempt-interest dividends attributable to interest on certain "private 
activity" tax-exempt obligations is a preference item for purposes of computing 
the alternative minimum tax for both individuals and corporations. Moreover, 
exempt-interest dividends, whether or not on private activity bonds, that are 
held by corporations will be taken into account (i) in determining the 
alternative minimum tax imposed on 75% of the excess of adjusted current 
earnings over alternative minimum taxable income, (ii) in calculating the 
environmental tax equal to 0.12 percent of a corporation's modified alternative 
minimum taxable income in excess of $2 million, and (iii) in determining the 
foreign branch profits tax imposed on the effectively connected earnings and 
profits (with adjustments) of United States branches of foreign corporations. 
The Fund plans to avoid to the extent possible investing in private activity 
tax-exempt obligations. 
 
  The Fund may be subject to state or local tax in certain other states where 
it is deemed to be doing business. Further, in those states which have income 
tax laws, the tax treatment of the Fund and of shareholders of the Fund with 
respect to distributions by the Fund may differ from federal tax treatment. The 
exemption of interest income for federal income tax purposes may not result in 
similar exemption under the laws of a particular state or local taxing 
authority. The Fund will report annually to its shareholders the percentage and 
source, on a state-by-state basis, of interest income on Municipal Bonds 
received by the Fund during the preceding year and on other aspects of the 
federal income tax status of distributions made by the Fund. Shareholders are 
urged to consult their own tax advisers regarding specific questions as to 
federal, state or local taxes.

                            PERFORMANCE INFORMATION
 
  Yield. The Fund may from time to time advertise its yield as calculated over 
a 30-day period. Yield is determined separately for Class A, Class B and Class 
C shares. The yield will be computed by dividing the Fund's net investment 
income per share earned during this 30-day period by the net asset value per 
share on the last day of this period. 
 
  Yield is calculated according to the following formula:
 
                         YIELD = 2 [ ( a  -  b +1)6-1]
cd
 
  Where: a = dividends and interest earned during the period.
b = expenses accrued for the period (net of reimbursements).
c = the average daily number of shares outstanding during the period that were 
  entitled to receive dividends. 
d = the maximum offering price per share on the last day of the period.
 
  The yield for the 30-day period ended December 31, 1997 for the Fund's Class 
A, Class B and Class C shares was 4.22%, 3.95% and 3.70%, respectively. 
 
  Yield fluctuates and an annualized yield quotation is not a representation by 
the Fund as to what an investment in the Fund will actually yield for any given 
period. Yield for the Fund will vary based on a number of factors including 
change in NAV, market conditions, the level of interest rates and the level of 
Fund income and expenses. 
 
  Tax Equivalent Yield. The Fund may also calculate the tax equivalent yield 
over a 30-day period. The tax equivalent yield is determined separately for 
Class A, Class B and Class C shares. The tax equivalent yield will be 
determined by first computing the yield as discussed above. The Fund will then 
determine what portion of the yield is attributable to securities, the income 
of which is exempt for federal income tax purposes. This portion of the yield 
will then be divided by one minus 39.6% (the assumed maximum tax rate for 
individual taxpayers not subject to Alternative Minimum Tax) and then added to 
the portion of the yield that is attributable to other securities. 
 
  Tax equivalent yield is calculated according to the following formula:
 
                         TAX EQUIVALENT YIELD =  Yield
- -----
1-.396
 
  The tax equivalent yield for the 30-day period ended December 31, 1997 for 
the Fund's Class A, Class B and Class C shares was 6.99%, 6.54% and 6.13%, 
respectively. 
 
  Average Annual Total Return. The Fund may also from time to time advertise 
its average annual total return. Average annual total return is determined 
separately for Class A, Class B and Class C shares. See "How the Fund 
Calculates Performance" in the Prospectus. 
 
  Average annual total return is computed according to the following formula:
 
                                  P(1+T)n=ERV
 
Where: P = a hypothetical initial payment of $1000.
T = average annual total return.
n = number of years.
ERV = Ending Redeemable Value at the end of the 1, 5 or 10 year periods (or 
    fractional portion thereof) of a hypothetical $1000 payment made at the 
    beginning of the 1, 5 or 10 year periods. 
 
  Average annual total return takes into account any applicable initial or 
contingent deferred sales charges but does not take into account any federal or 
state income taxes that may be payable upon redemption. 
 
  The average annual total return (adjusted for management fee waiver) with 
respect to the Class A shares for the one year, five year and since inception 
(January 22, 1990) periods ended December 31, 1997 was 6.50%, 6.23% and 7.51%, 
respectively. The average annual total return (adjusted for management fee 
waiver) with respect to the Class B shares of the Fund for the one, five, and 
ten year periods ended on December 31, 1997 was 4.35%, 6.31% and 7.69%, 
respectively. The average annual total return (adjusted for management fee 
waiver) for Class C shares for the one year and since inception (August 1, 
1994) periods ended December 31, 1997 was 8.08% and 6.98%, respectively. 
                                      B-23

  The average annual total return (before management fee waiver) with respect 
to the Class A shares for the one year, five year and since inception (January 
22, 1990) periods ended December 31, 1997 was 6.44%, 6.20% and 7.50%, 
respectively. The average annual total return (before management fee waiver) 
with respect to the Class B shares of the Fund for the one, five and ten-year 
periods ended on December 31, 1997 was 4.28%, 6.28% and 7.68%, respectively. 
The average annual total return (before management fee waiver) for Class C 
shares for the one year and since inception (August 1, 1994) periods ended 
December 31, 1997 was 8.01% and 6.94%, respectively. 
 
  (PIFM eliminated its management fee waiver of .05 of 1%, effective September 
1, 1997. See "Fee Waivers" in the Prospectus.) 
 
  Aggregate Total Return. The Fund may from time to time advertise its 
aggregate total return. Aggregate total return is determined separately for 
Class A, Class B and Class C shares. See "How the Fund Calculates Performance" 
in the Prospectus. 
 
  Aggregate total return represents the cumulative change in the value of an 
investment in the Fund and is computed by the following formula: 
 
                                    ERV - P
                                       P
 
Where:
P   =
a hypothetical initial payment of $1000.
ERV =
Ending Redeemable Value at the end of the 1, 5, or 10 year periods (or 
fractional portion thereof) of a 
hypothetical $1000 investment made at the beginning of the 1, 5 or 10 year 
periods. 
 
  Aggregate total return does not take into account any federal or state income 
taxes that may be payable upon redemption or any applicable initial or 
contingent deferred sales charges. 
 
  The aggregate total return (after management fee waiver) with respect to the 
Class A shares for the one year, five year and since inception (January 22, 
1990) periods ended December 31, 1997 was 9.80%, 39.44% and 83.23%, 
respectively. The aggregate total return (after management fee waiver) with 
respect to the Class B shares of the Fund for the one, five and ten-year 
periods ended on December 31, 1997 was 9.35%, 36.76% and 109.77%, respectively. 
The aggregate total return (after management fee waiver) for Class C shares for 
the one year and since inception (August 1, 1994) periods ended December 31, 
1997 was 9.08% and 25.92%, respectively. 
 
  The aggregate total return (before management fee waiver) with respect to the 
Class A shares for the one year, five year and since inception (January 22, 
1990) periods ended December 31, 1997 was 9.73%, 39.26% and 83.01%, 
respectively. The aggregate total return (before management fee waiver) with 
respect to the Class B shares of the Fund for the one, five and ten-year 
periods ended on December 31, 1997 was 9.28%, 36.59% and 109.51%, respectively. 
The aggregate total return (before management fee waiver) for Class C shares 
for the one year and since inception (August 1, 1994) periods ended December 
31, 1997 was 9.01% and 25.77%, respectively.

                   DESCRIPTION OF TAX-EXEMPT SECURITY RATINGS
 
Corporate and Tax-Exempt Bond Ratings
 
  The four highest ratings of Moody's Investors Service ("Moody's") for 
tax-exempt and corporate bonds are Aaa, Aa, A and Baa. Bonds rated Aaa are 
judged to be of the "best quality." The rating of Aa is assigned to bonds which 
are of "high quality by all standards," but as to which margins of protection 
or other elements make long-term risks appear somewhat larger than Aaa rated 
bonds. The Aaa and Aa rated bonds comprise what are generally known as "high 
grade bonds." Bonds which are rated A by Moody's possess many favorable 
investment attributes and are considered "upper medium grade obligations." 
Factors giving security to principal and interest of A rated bonds are 
considered adequate, but elements may be present which suggest a susceptibility 
to impairment sometime in the future. Bonds rated Baa are considered as "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. Moody's applies numerical modifiers "1", "2", and "3" in each generic 
rating classification from Aa through B in its corporate bond rating system. 
The modifier "1" indicates that the security ranks in the higher end of its 
generic rating category; the modifier "2" indicates a mid-range ranking; and 
the modifier "3" indicates that the issue ranks in the lower end of its generic 
rating category. The forgoing ratings for tax-exempt bonds are sometimes 
presented in parentheses preceded with a "con" indicating the bonds are rated 
conditionally. Bonds for which the security depends upon the completion of some 
act or the fulfillment of some condition are rated conditionally. These are 
bonds secured by (a) earnings of projects under construction, (b) earnings of 
projects unseasoned in operation experience, (c) rentals which begin when 
facilities are completed or (d) payments to which some other limiting condition 
attaches. Such parenthetical rating denotes the probable credit stature upon 
completion of construction or elimination of the basis of the condition. 
 
  The four highest ratings of Standard & Poor's Ratings Group ("Standard & 
Poor's") for tax-exempt and corporate bonds are AAA, AA, A and BBB. Bonds rated 
AAA bear the highest rating assigned by Standard & Poor's to a debt obligation 
and indicate an extremely strong capacity to pay principal and interest. Bonds 
rated AA also qualify as high-quality debt obligations. Capacity to pay 
principal and interest is very strong, and in the majority of instances they 
differ from AAA issues only in small degree. Bonds rated A have a strong 
capacity to pay principal and interest, although they are somewhat more 
susceptible to the adverse effects of changes in circumstances and economic 
conditions. The BBB rating, which is the lowest "investment grade" security 
rating by Standard & Poor's, indicates an adequate capacity to pay principal 
and interest. Whereas they normally exhibit adequate protection parameters, 
adverse economic conditions or changing circumstances are more likely to lead 
to a weakened capacity to pay principal and interest for bonds in this category 
than for bonds in the A category. The foregoing ratings are sometimes followed 
by a "p" indicating that the rating is provisional. A provisional rating 
assumes the successful completion of the project being financed by the bonds 
being rated and indicates that payment of debt service requirements is largely 
and entirely dependent upon the successful and timely completion of the 
project. This rating, however, while addressing credit quality subsequent to 
completion of the project, makes no comment on the likelihood of, or the risk 
of default upon failure of, such completion. 
 
Tax-Exempt Note Ratings
 
  The ratings of Moody's for tax-exempt notes are MIG 1, MIG 2, MIG 3 and MIG 
4. Notes bearing the designation MIG 1 are judged to be of the best quality, 
enjoying strong protection from established cash flows of funds for their 
servicing or from established and broad-based access to the market for 
refinancing, or both. Notes bearing the designation MIG 2 are judged to be of 
high quality, with margins of protection ample although not so large as in the 
preceding group. Notes bearing the designation MIG 3 are judged to be of 
favorable quality, with all security elements accounted for but lacking the 
undeniable strength of the preceding grades. Market access for refinancing, in 
particular, is likely to be less well established. Notes bearing the 
designation MIG 4 are judged to be of adequate quality, carrying specific risk 
but having protection commonly regarded as required of an investment security 
and not distinctly or predominantly speculative. 
 
  The ratings of Standard & Poor's for municipal notes issued on or after July 
29, 1984 are "SP-1" "SP-2" and "SP-3". Prior to July 29, 1984, municipal notes 
carried the same symbols as municipal bonds. The designation "SP-1" indicates a 
very strong capacity to pay principal and interest. A "+" is added for those 
issues determined to possess overwhelming safety characteristics. An "SP-2" 
designation indicates a satisfactory capacity to pay principal and interest 
while an "SP-3" designation indicates speculative capacity to pay principal and 
interest. 
                                      I-1

Corporate and Tax-Exempt Commercial Paper Ratings
 
  Moody's and Standard & Poor's rating grades for commercial paper, set forth 
below, are applied to Municipal Commercial Paper as well as taxable commercial 
paper. 
 
  Moody's Commercial Paper ratings are opinions of the ability of issuers to 
repay punctually promissory obligations not having an original maturity in 
excess of nine months. Moody's employs the following three designations, all 
judged to be investment grade, to indicate the relative repayment capacity of 
rate issuers: Prime-1, superior capacity; Prime-2, strong capacity; and 
Prime-3, acceptable capacity. 
 
  Standard & Poor's commercial paper rating is a current assessment of the 
likelihood of timely payment of debt having an original maturity of no more 
than 365 days. Ratings are graded into four categories, ranging from "A" for 
the highest quality obligations to "D" for the lowest. Issues assigned A 
ratings are regarded as having the greatest capacity for timely payment. Issues 
in this category are further refined with the designation 1, 2 and 3 to 
indicate the relative degree of safety. The "A-1" designation indicates the 
degree of safety regarding timely payment is very strong. A "+" designation is 
applied to those issues rated "A-1" which possess an overwhelming degree of 
safety. The "A-2" designation indicates that capacity for timely payment is 
strong. However, the relative degree of safety is not as overwhelming as for 
issues designated "A-1." The "A-3" designation indicates that the capacity for 
timely payment is satisfactory. Such issues, however, are somewhat more 
vulnerable to the adverse effects of changes in circumstances than obligations 
carrying the higher designations. Issues rated "B" are regarded as having only 
an adequate capacity for timely payment and such capacity may be impaired by 
changing conditions or short-term adversities.

                                  APPENDIX II
                         GENERAL INVESTMENT INFORMATION
 
  The following terms are used in mutual fund investing.
 
Asset Allocation
 
  Asset allocation is a technique for reducing risk, providing balance. Asset 
allocation among different types of securities within an overall investment 
portfolio helps to reduce risk and to potentially provide stable returns, while 
enabling investors to work toward their financial goal(s). Asset allocation is 
also a strategy to gain exposure to better performing asset classes while 
maintaining investment in other asset classes. 
 
Diversification
 
  Diversification is a time-honored technique for reducing risk, providing 
"balance" to an overall portfolio and potentially achieving more stable 
returns. Owning a portfolio of securities mitigates the individual risks (and 
returns) of any one security. Additionally, diversification among types of 
securities reduces the risks and (general returns) of any one type of security. 
 
Duration
 
  Debt securities have varying levels of sensitivity to interest rates. As 
interest rates fluctuate, the value of a bond (or a bond portfolio) will 
increase or decrease. Longer term bonds are generally more sensitive to changes 
in interest rates. When interest rates fall, bond prices generally rise. 
Conversely, when interest rates rise, bond prices generally fall. 
 
  Duration is an approximation of the price sensitivity of a bond (or a bond 
portfolio) to interest rate changes. It measures the weighted average maturity 
of a bond's (or a bond portfolio's) cash flows, i.e., principal and interest 
rate payments. Duration is expressed as a measure of time in years-the longer 
the duration of a bond (or a bond portfolio), the greater the impact of 
interest rate changes on the bond's (or the bond portfolio's) price. Duration 
differs from effective maturity in that duration takes into account call 
provisions, coupon rates and other factors. Duration measures interest rate 
risk only and not other risks, such as credit risk and, in the case of non-U.S. 
dollar denominated securities, currency risk. Effective maturity measures the 
final maturity dates of a bond (or a bond portfolio). 
 
Market Timing
 
  Market timing-buying securities when prices are low and selling them when 
prices are relatively higher-may not work for many investors because it is 
impossible to predict with certainty how the price of a security will 
fluctuate. However, owning a security for a long period of time may help 
investors offset short-term price volatility and realize positive returns. 
 
Power of Compounding
 
  Over time, the compounding of returns can significantly impact investment 
returns. Compounding is the effect of continuous investment on long-term 
investment results, by which the proceeds of capital appreciation (and income 
distributions, if elected) are reinvested to contribute to the overall growth 
of assets. The long-term investment results of compounding may be greater than 
that of an equivalent initial investment in which the proceeds of capital 
appreciation and income distributions are taken in cash. 
 
Standard Deviation
 
  Standard deviation is an absolute (non-relative) measure of volatility which, 
for a mutual fund, depicts how widely the returns varied over a certain period 
of time. When a fund has a high standard deviation, its range of performance 
has been very wide, implying greater volatility potential. Standard deviation 
is only one of several measures of a fund's volatility. 
                                      II-1

                          HISTORICAL PERFORMANCE DATA
 
  The historical performance data contained in this Appendix relies on data 
obtained from statistical services, reports and other services believed by the 
Manager to be reliable. The information has not been independently verified by 
the Manager. 
 
  This chart shows the long-term performance of various asset classes and the 
rate of inflation.

purposes only and is not indicative of the past, present, or future performance 
of any asset class or any Prudential Mutual Fund. 
 
Generally, stock returns are attributable to capital appreciation and the 
reinvestment of distributions. Bond returns are attributable mainly to the 
reinvestment of distributions. Also, stock prices are usually more volatile 
than bond prices over the long-term. 
 
Small stock returns for 1926-1989 are those of stocks comprising the 5th 
quintile of the New York Stock Exchange. Thereafter, returns are those of the 
Dimensional Fund Advisors (DFA) Small Company Fund. Common stock returns are 
based on the S&P Composite Index, a market-weighted, unmanaged index of 500 
stocks (currently) in a variety of industries. It is often used as a broad 
measure of stock market performance. 
 
Long-term government bond returns are represented by a portfolio that contains 
only one bond with a maturity of roughly 20 years. At the beginning of each 
year a new bond with a then-current coupon replaces the old bond. Treasury bill 
returns are for a one-month bill. Treasuries are guaranteed by the government 
as to the timely payment of principal and interest; equities are not. Inflation 
is measured by the consumer price index (CPI). 
 
Impact of Inflation. The "real" rate of investment return is that which exceeds 
the rate of inflation, the percentage change in the value of consumer goods and 
the general cost of living. A common goal of long-term investors is to outpace 
the erosive impact of inflation on investment returns.

  Set forth below is historical performance data relating to various sectors of 
the fixed-income securities markets. The chart shows the historical total 
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds, 
U.S. high yield bonds and world government bonds on an annual basis from 1987 
to September 1996. The total returns of the indices include accrued interest, 
plus the price changes (gains or losses) of the underlying securities during 
the period mentioned. The data is provided to illustrate the varying historical 
total returns and investors should not consider this performance data as an 
indication of the future performance of the Fund or of any sector in which the 
Fund invests. 
 
  All information relies on data obtained from statistical services, reports 
and other services believed by the Manager to be reliable. Such information has 
not been verified. The figures do not reflect the operating expenses and fees 
of a mutual fund. See "Fund Expenses" in the prospectus. The net effect of the 
deduction of the operating expenses of a mutual fund on these historical total 
returns, including the compounded effect over time, could be substantial.

  From time to time, there may be media coverage of portfolio managers and 
other investment professionals associated with the Manager and the Subadviser 
in national and regional publications, on television and in other media. 
Additionally, individual mutual fund portfolios are frequently cited in surveys 
conducted by national and regional publications and media organizations such as 
The Wall Street Journal, The New York Times, Barron's and USA Today. 
 
  Equity Funds. Forbes magazine listed Prudential Equity Fund among twenty 
mutual funds on its Honor Roll in its mutual fund issue of August 28, 1995. 
Honorees are chosen annually among mutual funds (excluding sector funds) which 
are open to new investors and have had the same management for at least five 
years. Forbes considers, among other criteria, the total return of a mutual 
fund in both bull and bear markets as well as a fund's risk profile. Prudential 
Equity Fund is managed with a "value" investment style by PIC. In 1995, 
Prudential Securities introduced Prudential Jennison Fund, a growth-style 
equity fund managed by Jennison Associates Capital Corp., a premier 
institutional equity manager and a subsidiary of Prudential. 
 
  High Yield Funds. Investing in high yield bonds is a complex and research 
intensive pursuit. A separate team of high yield bond analysts monitor 
approximately 200 issues held in the Prudential High Yield Fund (currently the 
largest fund of its kind in the country) along with 100 or so other high yield 
bonds, which may be considered for purchase.3 Non-investment grade bonds, also 
known as junk bonds or high yield bonds, are subject to a greater risk of loss 
of principal and interest including default risk than higher-rated bonds. 
Prudential high yield portfolio managers and analysts meet face-to-face with 
almost every bond issuer in the High Yield Fund's portfolio annually, and have 
additional telephone contact throughout the year. 
 
  Prudential's portfolio managers are supported by a large and sophisticated 
research organization. Fourteen investment grade bond analysts monitor the 
financial viability of approximately 1,750 different bond issuers in the 
investment grade corporate and municipal bond markets-from IBM to small 
municipalities, such as Rockaway Township, New Jersey. These analysts consider 
among other things sinking fund provisions and interest coverage ratios. 
 
  Prudential's portfolio managers and analysts receive research services from 
almost 200 brokers and market service vendors. They also receive nearly 100 
trade publications and newspapers-from Pulp and Paper Forecaster to Women's 
Wear Daily-to keep them informed of the industries they follow. 
 
  Prudential Mutual Funds' traders scan over 100 computer monitors to collect 
detailed information on which to trade. From natural gas prices in the Rocky 
Mountains to the results of local municipal elections, a Prudential portfolio 
manager or trader is able to monitor it if it's important to a Prudential 
mutual fund. 
 
  Prudential Mutual Funds trade approximately $31 billion in U.S. and foreign 
government securities a year. PIC seeks information from government policy 
makers. In 1995, Prudential's portfolio managers met with several senior U.S. 
and foreign government officials, on issues ranging from economic conditions in 
foreign countries to the viability of index-linked securities in the United 
States. 
 
  Prudential Mutual Funds' portfolio managers and analysts met with over 1,200 
companies in 1995, often with the Chief Executive Officer (CEO) or Chief 
Financial Officer (CFO). They also attended over 250 industry conferences. 
 
  Prudential Mutual Fund global equity managers conducted many of their visits 
overseas, often holding private meetings with a company in a foreign language 
(our global equity managers speak 7 different languages, including Mandarin 
Chinese). 
 
  Trading Data.4 On an average day, Prudential Mutual Funds' U.S. and foreign 
equity trading desks traded $77 million in securities representing over 3.8 
million shares with nearly 200 different firms. Prudential Mutual Funds' bond 
trading desks traded $157 million in government and corporate bonds on an 
average day. That represents more in daily trading than most bond funds tracked 
by Lipper even have in assets.5 Prudential Mutual Funds' money market desk 
traded $3.2 billion in money market securities on an average day, or over $800 
billion a year. They made a trade every 3 minutes of every trading day. In 
1994, the Prudential Mutual Funds effected more than 40,000 trades in money 
market securities and held on average $20 billion of money market securities.6

Notes to Financial Statements          PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.
- --------------------------------------------------------------------------------
Prudential National Municipals Fund, Inc. (the 'Fund') is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to seek a high level of current
income exempt from federal income taxes by investing substantially all of its
total assets in carefully selected long-term municipal bonds of medium quality.
The ability of the issuers of debt securities held by the Fund to meet their
obligations may be affected by economic or political developments in a specific
state, industry or region.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.
Securities Valuations: The Fund values municipal securities (including
commitments to purchase such securities on a 'when-issued' basis) on the basis
of prices provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Board of Directors.
Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.
Options: The Fund may either purchase or write options in order to hedge against
adverse market movements or fluctuations in value caused by changes in
prevailing interest rates with respect to securities which the Fund currently
owns or intends to purchase. The Fund's principal reason for writing options is
to realize, through receipt of premiums, a greater current return than would be
realized on the underlying security alone. When the Fund purchases an option, it
pays a premium and an amount equal to that premium is recorded as an investment.
When the Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Fund realizes a gain or loss to the extent of the premium
received or paid. If an option is exercised, the premium received or paid is an
adjustment to the proceeds from the sale or the cost of the purchase in
determining whether the Fund has realized a gain or loss. The difference between
the premium and the amount received or paid on effecting a closing purchase or
sale transaction is also treated as a realized gain or loss. Gain or loss on
purchased options is included in net realized gain (loss) on investment
transactions. Gain or loss on written options is presented separately as net
realized gain (loss) on written option transactions.
The Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Fund bears the market risk of an unfavorable change in the price of the security
underlying the written option. The Fund, as purchaser of an option, bears the
risk of the potential inability of the counterparties to meet the terms of their
contracts.
Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain(loss) on financial futures
contracts.
The Fund invests in financial futures contracts in order to hedge its existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value caused by changes in prevailing interest rates. Should
interest rates move unexpectedly, the Fund may not achieve the anticipated
benefits of the financial futures contracts and may realize a loss. The use of
futures transactions involves the risk of imperfect correlation in movements in
the price of futures contracts, interest rates and the underlying hedged assets.
Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of portfolio
securities are calculated on an identified cost basis. Interest income is
recorded on an accrual basis. The Fund amortizes premiums and accretes original
issue discount on portfolio securities as adjustments to interest income.
Expenses are recorded on the accrual basis which may require the use of certain
estimates by management.
Net investment income (other than distribution fees) and unrealized and realized
gains or losses are allocated daily to each class of shares based upon the
relative proportion of net assets of each class at the beginning of the day.

Notes to Financial Statements          PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.
- --------------------------------------------------------------------------------
Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with Statement of Position 93-2:
Determination, Disclosure and Financial Statement Presentation of Income,
Capital Gain and Return of Capital Distributions by Investment Companies. The
effect of applying this statement was to increase undistributed net investment
income and decrease accumulated realized gain on investment by $196,161. The
current year effect of applying the Statement of Position was due to the sale of
securities purchased with market discount. Net investment income, net realized
gains and net assets were not affected by this change.
Federal Income Taxes: It is the intent of the Fund to continue to meet the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its net income to its shareholders. For this
reason, no federal income tax provision is required.
Dividends and Distributions: Dividends from net investment income are declared
daily and paid monthly. The Fund will distribute at least annually any net
capital gains. Dividends and distributions are recorded on the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
Custody Fee Credits: The Fund has an arrangement with its custodian bank,
whereby uninvested monies earn credits which reduce the fees charged by the
custodian.
- ------------------------------------------------------------
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the cost of the
subadviser's services, the compensation of officers of the Fund, occupancy and
certain clerical and bookkeeping costs of the Fund. The Fund bears all other
costs and expenses.
The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .50% of the Fund's average daily net assets up to and including $250
million, .475% of the next $250 million, .45% of the next $500 million, .425% of
the next $250 million, .40% of the next $250 million and .375% of the Fund's
average daily net assets in excess of $1.5 billion. Prior to September 1, 1997,
PIFM had agreed to waive a portion (.05 of 1% of the Fund's average daily net
assets) of its management fee which amounted to $215,979 ($.005 per share for
Class A, B and C shares). The Fund is not required to reimburse PIFM for such
waiver. Effective September 1, 1997, PIFM eliminated its management fee waiver.
The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class B and Class C
shares of the Fund. The Fund compensates PSI for distributing and servicing the
Fund's Class A, Class B and Class C shares, pursuant to plans of distribution
(the 'Class A, B and C Plans'), regardless of expenses actually incurred by
them. The distribution fees are accrued daily and payable monthly.
Pursuant to the Class A, B and C Plans, the Fund compensates PSI with respect to
Class A, B and C shares, for distribution-related activities at an annual rate
of up to .30 of 1%, .50 of 1% and 1%, of the average daily net assets of the
Class A, B and C shares, respectively. Such expenses under the Plans were .10 of
1%, .50 of 1% and .75 of 1% of the average daily net assets of the Class A, B
and C shares, respectively, for the year ended December 31, 1997.
PSI has advised the Fund that it received approximately $52,100 in front-end
sales charges resulting from sales of Class A shares during the year ended
December 31, 1997. From these fees, PSI paid such sales charges to dealers,
which in turn paid commissions to salespersons and incurred other distribution
costs.
PSI has advised the Fund that for the year ended December 31, 1997, it received
approximately $274,100 and $200 in contingent deferred sales charges imposed
upon certain redemptions by Class B and Class C shareholders, respectively.
PSI, PIFM and PIC are indirect, wholly owned subsidiaries of The Prudential
Insurance Company of America.
The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the year ended
December 31, 1997. The Funds pay a commitment fee at an annual rate of .055 of
1% on the unused portion of the credit facility. The commitment fee is

- --------------------------------------------------------------------------------
accrued and paid quarterly on a pro rata basis by the Funds. The Agreement
expired on December 30, 1997 and has been extended through December 29, 1998
under the same terms.
- ------------------------------------------------------------
Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent and during the year ended December 31, 1997,
the Fund incurred fees of approximately $413,100 for the services of PMFS. As of
December 31, 1997, $33,200 of such fees were due to PMFS. Transfer agent fees
and expenses in the Statement of Operations include certain out-of-pocket
expenses paid to non affiliates.
- ------------------------------------------------------------
Note 4. Portfolio Securities
Purchases and sales of investment securities, other than short-term investments,
for the year ended December 31, 1997, were $237,337,219 and $315,859,062,
respectively.
The federal income tax basis of the Fund's investments at December 31, 1997 was
substantially the same as for financial reporting purposes and, accordingly, net
and gross unrealized appreciation for federal income tax purposes was
$51,206,818.
The Fund utilized its capital loss carryforward of approximately $3,010,300 to
offset net taxable gains recognized during the year ended December 31, 1997.
During the year ended December 31, 1997, the Fund entered into financial futures
contracts. Details of open contracts at December 31, 1997 are as follows:

Report of Independent Accountants      PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of
Prudential National Municipals Fund, Inc.
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential National Municipals
Fund, Inc. (the 'Fund') at December 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended and the financial highlights for each of the periods
presented, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
'financial statements') are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
December 31, 1997 by correspondence with the custodian and brokers and the
application of alternative auditing procedures where confirmations from brokers
were not received, provide a reasonable basis for the opinion expressed above.

Tax Information                        PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.
- --------------------------------------------------------------------------------
We are required by the Internal Revenue Code to advise you within 60 days of the
Fund's fiscal year end (December 31, 1997) as to the federal tax status of
dividends paid by the Fund during such fiscal year. Accordingly, we are advising
you that in the fiscal year ended December 31, 1997, dividends paid from net
investment income totalling $.81 per Class A share, $.75 per Class B share and
$.71 per Class C shares were all federally tax-exempt interest dividends. In
addition, the Fund paid an ordinary distribution of $.005 per share (taxable as
ordinary income) and a long-term capital gain distribution of $.104 of which
$.063 is taxable at 28% and $.041 is taxable at 20%.
The portion of your dividends which may be subject to the Alternative Minimum
Tax (AMT) as well as information with respect to the state taxability of your
investment in the Fund was sent to you under separate cover.
For the purpose of preparing your annual federal income tax return, however, you
should report the amounts as reflected on the appropriate Form 1099-DIV or
substitute 1099-DIV.

(Unaudited)                           PRUDENTIAL NATIONAL MUNICIPALS FUND, INC.
- --------------------------------------------------------------------------------
Prudential National Municipals Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to seek a high level of current
income exempt from federal income taxes by investing substantially all of its
total assets in carefully selected long-term municipal bonds of medium quality.
The ability of the issuers of debt securities held by the Fund to meet their
obligations may be affected by economic or political developments in a specific
state, industry or region.
- ------------------------------------------------------------
Note 1. Accounting Policies

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

Securities Valuations: The Fund values municipal securities (including
commitments to purchase such securities on a "when-issued" basis) on the basis
of prices provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Board of Directors. All Securities are valued as
of 4:15 p.m., New York time.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

Options: The Fund may either purchase or write options in order to hedge against
adverse market movements or fluctuations in value caused by changes in
prevailing interest rates with respect to securities which the Fund currently
owns or intends to purchase. The Fund's principal reason for writing options is
to realize, through receipt of premiums, a greater current return than would be
realized on the underlying security alone. When the Fund purchases an option, it
pays a premium and an amount equal to that premium is recorded as an investment.
When the Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Fund realizes a gain or loss to the extent of the premium
received or paid. If an option is exercised, the premium received or paid is an
adjustment to the proceeds from the sale or the cost of the purchase in
determining whether the Fund has realized a gain or loss. The difference between
the premium and the amount received or paid on effecting a closing purchase or
sale transaction is also treated as a realized gain or loss. Gain or loss on
purchased options is included in net realized gain (loss) on investment
transactions. Gain or loss on written options is presented separately as net
realized gain (loss) on written option transactions.

The Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Fund bears the market risk of an unfavorable change in the price of the security
underlying the written option. The Fund, as purchaser of an option, bears the
risk of the potential inability of the counterparties to meet the terms of their
contracts.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Fund is required to pledge to the broker an amount of cash and/or other
assets equal to a certain percentage of the contract amount. This amount is
known as the 'initial margin.' Subsequent payments, known as 'variation margin,'
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying security. Such variation margin is recorded for
financial statement purposes on a daily basis as unrealized gain or loss. When
the contract expires or is closed, the gain or loss is realized and is presented
in the statement of operations as net realized gain(loss) on financial futures
contracts.

The Fund invests in financial futures contracts in order to hedge its existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value caused by changes in prevailing interest rates. Should
interest rates move unexpectedly, the Fund may not achieve the anticipated
benefits of the financial futures contracts and may realize a loss. The use of
futures transactions involves the risk of imperfect correlation in movements in
the price of futures contracts, interest rates and the underlying hedged assets.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of portfolio
securities are calculated on an identified cost basis. Interest income is
recorded on an accrual basis. The Fund amortizes premiums and accretes original
issue discount on portfolio securities as adjustments to interest income.
Expenses are recorded on the accrual basis which may require the use of certain
estimates by management.

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

- --------------------------------------------------------------------------------
Federal Income Taxes: It is the intent of the Fund to continue to meet the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its net income to its shareholders. For this
reason, no federal income tax provision is required.

Dividends and Distributions: Dividends from net investment income are declared
daily and paid monthly. The Fund will distribute at least annually any net
capital gains. Dividends and distributions are recorded on the ex-dividend date.

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

Custody Fee Credits: The Fund has an arrangement with its custodian bank,
whereby uninvested monies earn credits which reduce the fees charged by the
custodian.
- ------------------------------------------------------------
Note 2. Agreements

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

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .50% of the Fund's average daily net assets up to and including $250
million, .475% of the next $250 million, .45% of the next $500 million, .425% of
the next $250 million, .40% of the next $250 million and .375% of the Fund's
average daily net assets in excess of $1.5 billion.

The Fund had a distribution agreement with Prudential Securities Incorporated
("PSI"), which acted as the distributor of the Class A, Class B and Class C
shares of the Fund. The Fund compensated PSI for distributing and servicing the
Fund's Class A, Class B and Class C shares, pursuant to plans of distribution
(the "Class A, B and C Plans"), regardless of expenses actually incurred by
them. The distribution fees were accrued daily and payable monthly. Effective
July 1, 1998, Prudential Investment Management Services LLC ("PIMS") became the
distributor of the Fund and is serving the Fund under the same terms and
conditions as under the arrangment with PSI.

Pursuant to the Class A, B and C Plans, the Fund compensated PSI with respect to
Class A, B and C shares, for distribution-related activities at an annual rate
of up to .30 of 1%, .50 of 1% and 1%, of the average daily net assets of the
Class A, B and C shares, respectively. Such expenses under the Plans were .10 of
1%, .50 of 1% and .75 of 1% of the average daily net assets of the Class A, B
and C shares, respectively, for the six months ended June 30, 1998.

PSI has advised the Fund that it received approximately $39,700 in front-end
sales charges resulting from sales of Class A shares during the six months ended
June 30, 1998. From these fees, PSI paid such sales charges to dealers, which in
turn paid commissions to salespersons and incurred other distribution costs.

PSI has advised the Fund that for the six months ended June 30, 1998, it
received approximately $71,500 in contingent deferred sales charges imposed upon
certain redemptions by Class B and Class C shareholders.

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

The Fund, along with other affiliated registered investment companies (the
"Funds"), has a credit agreement (the "Agreement") with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund did not borrow any amounts pursuant to the Agreement during the six months
ended June 30, 1998. The Funds pay a commitment fee at an annual rate of .055 of
1% on the unused portion of the credit facility. The commitment fee is accrued
and paid quarterly on a pro rata basis by the Funds. The Agreement expires on
December 29, 1998.
- ------------------------------------------------------------
Note 3. Other Transactions with Affiliates

Prudential Mutual Fund Services LLC ("PMFS"), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent and during the six months ended June 30,
1998, the Fund incurred fees of approximately $196,200 for the services of PMFS.
As of June 30, 1998, $32,400 of such fees were due to PMFS. Transfer agent fees
and expenses in the Statement of Operations include certain out-of-pocket
expenses paid to nonaffiliates.

Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments,
for the six months ended June 30, 1998, were $86,131,037 and $113,863,128,
respectively.

The federal income tax basis of the Fund's investments at June 30, 1998 was
substantially the same as for financial reporting purposes and, accordingly, net
unrealized appreciation for federal income tax purposes was $46,972,767 (gross
unrealized appreciation--$47,016,655; gross unrealized depreciation--$43,888).

During the six months ended June 30, 1998, the Fund entered into financial
futures contracts. Details of open contracts at June 30, 1998 are as follows:

- --------------------------------------------------------------------------------
Prudential Municipal Bond Fund (the 'Fund') is registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
The Fund was organized as an unincorporated business trust in Massachusetts on
November 3, 1986 and consists of three series: the High Yield Series, the
Insured Series and the Intermediate Series. Investment operations for Class A,
Class B, Class C and Class Z shares of each series commenced on January 22,
1990, September 17, 1987, August 1, 1994 and September 16, 1996, respectively.

The investment objectives of the series are as follows: (i) the objective of the
High Yield Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes, (ii) the objective of the Insured and
Intermediate Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes consistent with the preservation of
capital. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic and political developments in a
specific state, region or industry.
- ------------------------------------------------------------
Note 1. Accounting Policies

Securities Valuation: Municipal securities (including commitments to purchase
such securities on a 'when-issued' basis) are valued on the basis of prices
provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of debt securities at a set
price for delivery on a future date. Upon entering into a financial futures
contract, the Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the 'initial margin.' Subsequent payments, known as 'variation
margin,' are made or received by the Fund each day, depending on the daily
fluctuations in the value of the underlying security. Such variation margin is
recorded for financial statement purposes on a daily basis as unrealized gain or
loss. When the contract expires or is closed, the gain or loss is realized and
is presented in the statement of operations as net realized gain (loss) on
financial futures contracts.

The Fund invests in financial futures contracts in order to hedge its existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value caused by changes in prevailing interest rates. Should
interest rates move unexpectedly, the Fund may not achieve the anticipated
benefits of the financial futures contracts and may realize a loss. The use of
futures transactions involves the risk of imperfect correlation in movements in
the price of futures contracts, interest rates and the underlying hedged assets.

Options: The Fund may either purchase or write options in order to hedge against
adverse market movements or fluctuations in value caused by changes in
prevailing interest rates with respect to securities which the Fund currently
owns or intends to purchase. When the Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Fund writes an option, it receives a premium and an amount equal to that
premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Fund realizes a gain or loss to the extent of the premium
received or paid. If an option is exercised, the premium received or paid is an
adjustment to the proceeds from the sale or the cost basis of the purchase in
determining whether the Fund has realized a gain or loss. The difference between
the premium and the amount received or paid on effecting a closing purchase or
sale transaction is also treated as a realized gain or loss. Gain or loss on
purchased options is included in net realized gain (loss) on investment
transactions.

The Fund, as writer of an option, has no control over whether the underlying
securities may be sold (called) or purchased (put). As a result, the Fund bears
the market risk of an unfavorable change in the price of the security underlying
the written option. The Fund, as purchaser of an option, bears the risk of the
potential inability of the counterparties to meet the terms of their contracts.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Interest income is recorded on the
accrual basis. The Fund amortizes premiums and accretes original issue discount
on portfolio securities as adjustments to interest income. Net investment
income, other than distribution fees, and realized and unrealized gains or
losses are allocated daily to each class of shares based upon the relative
proportion of net assets of each class at the beginning of the day. Expenses are
recorded on the accrual basis which may require the use of certain estimates by
management.

- --------------------------------------------------------------------------------
Federal Income Taxes: For federal income tax purposes, each series in the Fund
is treated as a separate tax paying entity. It is the intent of each series to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all net income to shareholders.
For this reason no federal income tax provision is required.

Dividends and Distributions: Dividends from net investment income are declared
daily and paid monthly. The Fund will distribute at least annually any net
capital gains. Dividends and distributions are recorded on the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with Statement of Position 93-2:
Determination, Disclosure, and Financial Statement Presentation of Income,
Capital Gain, and Return of Capital Distributions by Investment Companies. For
the fiscal year ended April 30, 1998, the effect of applying this statement was
to increase undistributed net investment income and decrease accumulated net
realized gain by $171,122 for the Insured Series.

Custody Fee Credits: The Fund has an arrangement with its custodian bank,
whereby uninvested monies earn credits which reduce the fees charged by the
custodian.
- ------------------------------------------------------------
Note 2. Agreements

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

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .50 of 1% of the average daily net assets of each series up to $1
billion and .45 of 1% of the average daily net assets of each series in excess
of $1 billion. PIFM has agreed to voluntarily waive a portion of each series'
management fee, which amounted to $535,931, $85,444 and $7,346 for the High
Yield Series, Insured Series and Intermediate Series, respectively. Such amounts
represented .05 of 1% of the average daily net assets or $.005 per share for the
High Yield Series and .02 of 1% of the average daily net assets or $.002 per
share for the Insured Series and Intermediate Series. Effective September 1,
1997, PIFM eliminated its management fee waiver for the Insured Series and
Intermediate Series.

The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund. The Fund compensates PSI for distributing and
servicing the Fund's Class A, Class B and Class C shares, pursuant to plans of
distribution (the 'Class A, B and C Plans'), regardless of expenses actually
incurred by PSI. The distribution fees are accrued daily and payable monthly. No
distribution or service fees are paid to PSI as distributor of the Class Z
shares of the Fund. Effective July 1, 1998, Prudential Investment Management
Services LLC will become the distributor of the Fund and will serve the Fund
under the same terms and conditions as under the arrangement with PSI.

Pursuant to the Class A, B and C Plans, the Fund compensates PSI for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1%, of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .10 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively,
for the year ended April 30, 1998.

PSI has advised the Fund that it received approximately $529,300 ($493,600-High
Yield Series; $30,400-Insured Series; $5,300-Intermediate Series) in front-end
sales charges resulting from sales of Class A shares during the year ended April
30, 1998. From these fees, PSI paid such sales charges to affiliated
broker-dealers which in turn paid commissions to salespersons and incurred other
distribution costs.

PSI has advised the Fund that for the year ended April 30, 1998, it received
approximately $1,320,700 ($866,900-High Yield Series; $388,200-Insured Series;
$65,600-Intermediate Series) in contingent deferred sales charges imposed upon
certain redemptions by Class B and C shareholders.

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

The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative

source of funding for capital share redemptions. The Fund has not borrowed any
amounts pursuant to the Agreement during the year ended April 30, 1998. The
Funds pay a commitment fee at an annual rate of .055 of 1% on the unused portion

Note 5. Capital

Each series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3.0%. Class B shares are sold
with a contingent deferred sales charge which declines from 5% to zero depending
on the period of time the shares are held. Class C shares are sold with a
contingent deferred sales charge of 1% during the first year. Class B shares
automatically convert to Class A shares on a quarterly basis approximately seven
years after purchase. A special exchange privilege is also available for
shareholders who qualify to purchase Class A shares at net asset value. Class Z
shares are not subject to any sales or redemption charge and are offered
exclusively for sale to a limited group of investors.

Report of Independent Accountants              PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
To the Shareholders and Trustees of
Prudential Municipal Bond Fund

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of High Yield Series, Insured Series
and Intermediate Series (constituting Prudential Municipal Bond Fund, hereafter
referred to as the 'Fund') at April 30, 1998, the results of each of their
operations for the year then ended and the changes in each of their net assets
and the financial highlights for each of the two years in the period then ended,
in conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at April 30, 1998 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above. The accompanying financial
highlights for each of the three years in the period ended April 30, 1996 were
audited by other independent accountants, whose opinion dated June 13, 1996 was
unqualified.

                               OTHER INFORMATION
 
ITEM 15. INDEMNIFICATION.
  As permitted by Section 17(h) and (i) of the Investment Company Act of 1940,
as amended (the 1940 Act) and pursuant to Article VII of the Fund's By-Laws
(Exhibit 2 to the Registration Statement), officers, directors, employees and
agents of the Registrant will not be liable to the Registrant, any shareholder,
officer, director, employee, agent or other person for any action or failure to
act, except for bad faith, willful misfeasance, gross negligence or reckless
disregard of duties, and those individuals may be indemnified against
liabilities in connection with the Registrant, subject to the same exceptions.
Section 2-418 of Maryland General Corporation Law permits indemnification of
directors who acted in good faith and reasonably believed that the conduct was
in the best interests of the Registrant. As permitted by Section 17(i) of the
1940 Act, pursuant to Section 10 of each Distribution Agreement (Exhibit 7 to
the Registration Statement), each Distributor of the Registrant may be
indemnified against liabilities which it may incur, except liabilities arising
from bad faith, gross negligence, willful misfeasance or reckless disregard of
duties.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (Securities Act) may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the 1940 Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in connection with the successful defense
of any action, suit or proceeding) is asserted against the Registrant by such
director, officer or controlling person in connection with the shares being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1940 Act and will be governed by the final
adjudication of such issue.
 
    The Registrant maintains an insurance policy insuring its officers and
directors against liabilities, and certain costs of defending claims against
such officers and directors, to the extent such officers and directors are not
found to have committed conduct constituting willful misfeasance, bad faith,
gross negligence or reckless disregard in the performance of their duties. The
insurance policy also insures the Registrant against the cost of indemnification
payments to officers and directors under certain circumstances.
 
    Section 9 of the Management Agreement (Exhibit 6(a) to the Registration
Statement) and Section 4 of the Subadvisory Agreement (Exhibit 6(b) to the
Registration Statement) limit the liability of Prudential Investment Fund
Management, LLC. (PIFM) and The Prudential Investment Corporation (PIC),
respectively, to liabilities arising from willful misfeasance, bad faith or
gross negligence in the performance of their respective duties or from reckless
disregard by them of their respective obligations and duties under the
agreements.
 
    The Registrant hereby undertakes that it will apply the indemnification
provisions of its By-Laws and each Distribution Agreement in a manner consistent
with Release No. 11330 of the Securities and Exchange Commission under the 1940
Act so long as the interpretation of Sections 17(h) and 17(i) of such Act remain
in effect and are consistently applied.

Appendix B
 
                      AGREEMENT AND PLAN OF REORGANIZATION
 

    Agreement and Plan of Reorganization (Agreement) made as of the     day of
November, 1998, by and between Prudential Municipal Bond Fund (Municipal Bond
Fund)--Intermediate Series and Prudential National Municipals Fund, Inc.
(National Municipals Fund) (collectively, with Intermediate Series and Municipal
Bond Fund, the Funds and each individually, a Fund). Municipal Bond Fund is a
business trust organized under the laws of the Commonwealth of Massachusetts and
the National Municipals Fund is a corporation organized under the laws of the
State of Maryland. Each Fund maintains its principal place of business at
Gateway Center Three, Newark, New Jersey 07102. Shares of National Municipals
Fund and Intermediate Series are divided into four classes, designated Class A,
Class B, Class C and Class Z. Municipal Bond Fund consists of three series, one
of which is Intermediate Series.

 
    This Agreement is intended to be, and is adopted as, a plan of
reorganization pursuant to Section 368(a)(1)(C) of the Internal Revenue Code of
1986, as amended (Internal Revenue Code). Upon receipt of such representations
from each of the Funds as Swidler Berlin Shereff Friedman, LLP may require,
Swidler Berlin Shereff Friedman, LLP will deliver the opinion referenced in
paragraph 8.6 herein. The reorganization will comprise the transfer of the
assets of Intermediate Series in exchange for shares of common stock of National
Municipals Fund, and National Municipals Fund's assumption of such Series'
liabilities, if any, and the constructive distribution, after the Closing Date
hereinafter referred to, of such shares of National Municipals Fund to the
shareholders of Intermediate Series, and the termination of Intermediate Series
as provided herein, all upon the terms and conditions as hereinafter set forth.
 
    In consideration of the premises and of the covenants and agreements set
forth herein, the parties covenant and agree as follows:
 
1.  TRANSFER OF ASSETS OF INTERMEDIATE SERIES IN EXCHANGE FOR SHARES OF NATIONAL
    MUNICIPALS FUND AND ASSUMPTION OF LIABILITIES, IF ANY, AND TERMINATION OF
    INTERMEDIATE SERIES
 

1.1  Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, Municipal Bond Fund on
behalf of Intermediate Series agrees to sell, assign, transfer and deliver the
assets of Intermediate Series, as set forth in paragraph 1.2, to National
Municipals Fund, and National Municipals Fund agrees (a) to issue and deliver to
Intermediate Series in exchange therefor the number of shares of Class A, Class
B, Class C and Class Z shares of Common Stock in National Municipals Fund
determined by dividing the net asset value of the Intermediate Series allocable
to Class A, Class B, Class C and Class Z shares of beneficial interest (computed
in the manner and as of the time and date set forth in paragraph 2.1) by the net
asset value allocable to a share of National Municipals Fund Class A, Class B,
Class C and Class Z shares of Common Stock (computed in the manner and as of the
time and date set forth in paragraph 2.2); and (b) to assume all of Intermediate
Series' liabilities, if any, as set forth in paragraph 1.3. Such transactions
shall take place at the closing provided for in paragraph 3 (Closing).

 
1.2  The assets of Intermediate Series to be acquired by National Municipals
Fund shall include without limitation all cash, cash equivalents, securities,
receivables (including interest and dividends receivable) and other property of
any kind owned by such Series and any deferred or prepaid expenses shown as
assets on the
 
                                     B-1(A)
<PAGE>
books of such Series on the closing date provided in paragraph 3 (Closing Date).
National Municipals Fund has no plan or intent to sell or otherwise dispose of
any assets of Intermediate Series, other than in the ordinary course of
business.
 
1.3  Except as otherwise provided herein, National Municipals Fund will assume
all debts, liabilities, obligations and duties of Intermediate Series of
whatever kind or nature, whether absolute, accrued, contingent or otherwise,
whether or not determinable as of the Closing Date and whether or not
specifically referred to in this Agreement; provided, however, that Intermediate
Series agrees to utilize its best efforts to cause such Series to discharge all
of the known debts, liabilities, obligations and duties of such Series prior to
the Closing Date.
 
1.4  On or immediately prior to the Closing Date, Intermediate Series will
declare and pay to its shareholders of record dividends and/or other
distributions so that it will have distributed substantially all (and in any
event not less than ninety-eight percent) of each of such Series' investment
company taxable income (computed without regard to any deduction for dividends
paid), net tax-exempt interest income, if any, and realized net capital gains,
if any, for all taxable years through its termination.
 

1.5  On a date (Termination Date), as soon after the Closing Date as is
conveniently practicable, but in any event within 30 days of the Closing Date,
Intermediate Series will distribute PRO RATA to its Class A, Class B, Class C
and Class Z shareholders of record, determined as of the close of business on
the Closing Date, the Class A, Class B, Class C and Class Z shares of National
Municipals Fund received by Intermediate Series pursuant to paragraph 1.1 in
exchange for their interest in such Series, and Municipal Bond Fund will file
with the Secretary of State of The Commonwealth of Massachusetts a Certificate
of Termination terminating Intermediate Series. Such distribution will be
accomplished by opening accounts on the books of National Municipals Fund in the
names of Intermediate Series' shareholders and transferring thereto the shares
credited to the account of Intermediate Series on the books of National
Municipals Fund. Each account opened shall be credited with the respective PRO
RATA number of National Municipals Fund Class A, Class B, Class C and Class Z
shares due such Series' Class A, Class B, Class C and Class Z shareholders,
respectively. Fractional shares of National Municipals Fund shall be rounded to
the third decimal place.

 
1.6  National Municipals Fund shall not issue certificates representing its
shares in connection with such exchange. With respect to any Intermediate Series
shareholder holding Intermediate Series receipts for shares of beneficial
interest as of the Closing Date, until National Municipals Fund is notified by
Municipal Bond Fund's transfer agent that such shareholder has surrendered his
or her outstanding Series receipts for shares of beneficial interest or, in the
event of lost, stolen or destroyed receipts for shares of beneficial interest,
posted adequate bond or submitted a lost certificate form, as the case may be,
National Municipals Fund will not permit such shareholder to (1) receive
dividends or other distributions on National Municipals Fund shares in cash
(although such dividends and distributions shall be credited to the account of
such shareholder established on National Municipals Fund's books pursuant to
paragraph 1.5, as provided in the next sentence), (2) exchange National
Municipals Fund shares credited to such shareholder's account for shares of
other Prudential Mutual Funds, or (3) pledge or redeem such shares. In the event
that a shareholder is not permitted to receive dividends or other distributions
on National Municipals Fund shares in cash as provided in the preceding
sentence, National Municipals Fund shall pay such dividends or other
distributions in additional National Municipals Fund shares, notwithstanding any
election such shareholder shall have made previously with respect to the payment
of dividends or other distributions on shares of Intermediate Series.
Intermediate Series will, at its expense, request its shareholders to surrender
their outstanding Intermediate Series receipts for shares of beneficial
interest, post adequate bond or submit a lost certificate form, as the case may
be.
 
                                     B-2(A)
<PAGE>
1.7  Ownership of National Municipals Fund shares will be shown on the books of
the National Municipals Fund's transfer agent. Shares of National Municipals
Fund will be issued in the manner described in National Municipals Fund's
then-current prospectus and statement of additional information.
 
1.8  Any transfer taxes payable upon issuance of shares of National Municipals
Fund in exchange for shares of Intermediate Series in a name other than that of
the registered holder of the shares being exchanged on the books of Intermediate
Series as of that time shall be paid by the person to whom such shares are to be
issued as a condition to the registration of such transfer.
 
1.9  Any reporting responsibility with the Securities and Exchange Commission
(SEC) or any state securities commission of Municipal Bond Fund with respect to
Intermediate Series is and shall remain the responsibility of Intermediate
Series up to and including the Termination Date.
 
1.10  All books and records of Intermediate Series, including all books and
records required to be maintained under the Investment Company Act of 1940
(Investment Company Act) and the rules and regulations thereunder, shall be
available to National Municipals Fund from and after the Closing Date and shall
be turned over to National Municipals Fund on or prior to the Termination Date.
 
2.  VALUATION
 
2.1  The value of Intermediate Series' assets and liabilities to be acquired and
assumed, respectively, by National Municipals Fund shall be the net asset value
computed as of 4:15 p.m., New York time, on the Closing Date (such time and date
being hereinafter called the Valuation Time), using the valuation procedures set
forth in Intermediate Series' then-current prospectus and Municipal Bond Fund's
statement of additional information.
 
2.2  The net asset value of a share of National Municipals Fund shall be the net
asset value per such share computed on a class-by-class basis as of the
Valuation Time, using the valuation procedures set forth in National Municipals
Fund's then-current prospectus and statement of additional information.
 
2.3  The number of National Municipals Fund shares to be issued (including
fractional shares, if any) in exchange for Intermediate Series' net assets shall
be calculated as set forth in paragraph 1.1.
 
2.4  All computations of net asset value shall be made by or under the direction
of Prudential Investments Fund Management LLC (PIFM) in accordance with its
regular practice as manager of the Funds.
 
3.  CLOSING AND CLOSING DATE
 

3.1  The Closing Date shall be December 18, 1998 or such later date as the
parties may agree in writing. All acts taking place at the Closing shall be
deemed to take place simultaneously as of the close of business on the Closing
Date unless otherwise provided. The Closing shall be at the office of National
Municipals Fund or at such other place as the parties may agree.

 
3.2  State Street Bank and Trust Company (State Street), as custodian for
Intermediate Series, shall deliver to National Municipals Fund at the Closing a
certificate of an authorized officer of State Street stating that (a)
Intermediate Series' portfolio securities, cash and any other assets have been
transferred in proper form to National Municipals Fund on the Closing Date and
(b) all necessary taxes, if any, have been paid, or provision for payment has
been made, in conjunction with the transfer of portfolio securities.
 
3.3  In the event that immediately prior to the Valuation Time (a) the New York
Stock Exchange (NYSE) or other primary exchange is closed to trading or trading
thereon is restricted or (b) trading or the reporting of trading on the NYSE or
other primary exchange or elsewhere is disrupted so that accurate appraisal of
the
 
                                     B-3(A)
<PAGE>
value of the net assets of Intermediate Series and of the net asset value per
share of National Municipals Fund is impracticable, the Closing Date shall be
postponed until the first business day after the date when such trading shall
have been fully resumed and such reporting shall have been restored.
 
3.4  Municipal Bond Fund shall deliver to National Municipals Fund on or prior
to the Termination Date the names and addresses of each of the shareholders of
Intermediate Series and the number of outstanding shares owned by each such
shareholder, all as of the close of business on the Closing Date, certified by
the Secretary or Assistant Secretary of Municipal Bond Fund. National Municipals
Fund shall issue and deliver to Municipal Bond Fund at the Closing a
confirmation or other evidence satisfactory to Municipal Bond Fund that shares
of National Municipals Fund have been or will be credited to Intermediate
Series' account on the books of National Municipals Fund. At the Closing each
party shall deliver to the other such bills of sale, checks, assignments, share
certificates, receipts and other documents as such other party or its counsel
may reasonably request to effect the transactions contemplated by this
Agreement.

    Municipals Fund and the assumption by National Municipals Fund of
    Intermediate Series' liabilities, if any, followed by the distribution of
    National Municipals Fund's voting shares pro rata to Intermediate Series'
    shareholders, pursuant to its termination and constructively in exchange for
    Intermediate Series' shares, will constitute a reorganization within the

    will be "a party to a reorganization" within the meaning of Section 368(b)
    of the Internal Revenue Code;

    distribution of those shares to Intermediate Series' shareholders in
    complete termination of Intermediate Series;
 
    8.6.4  No gain or loss will be recognized to National Municipals Fund upon
    the acquisition of Intermediate Series' assets solely in exchange for shares
    of National Municipals Fund and the assumption of Intermediate Series'

    8.6.5  National Municipals Fund's basis for the assets of Intermediate
    Series acquired in the Reorganization will be the same as the basis thereof
    when held by Intermediate Series immediately before the transfer, and the
    holding period of such assets acquired by National Municipals Fund will
    include the holding period thereof when held by Intermediate Series;
 
    8.6.6  Intermediate Series shareholders' basis for the shares of National
    Municipals Fund to be received by them pursuant to the reorganization will
    be the same as their basis for the shares of Intermediate Series to be
    constructively surrendered in exchange therefor; and
 
    8.6.7  The holding period of National Municipals Fund shares to be received
    by Intermediate Series' shareholders will include the period during which
    the shares of Intermediate Series to be constructively surrendered in
    exchange therefor were held; provided that the Intermediate Series shares
    surrendered were held as capital assets by those shareholders on the date of
    the exchange.

Appendix B
 
                     AGREEMENT AND PLAN OF REORGANIZATIONS
 

    Agreement and Plan of Reorganizations (Agreement) made as of the    day of
November, 1998, by and between Prudential Municipal Series Fund (Series
Fund)--Maryland Series and Michigan Series and Prudential National Municipals
Fund, Inc. (National Municipals Fund and, collectively with Series Fund, the
Funds and each individually, a Fund). The Series Fund is a business trust
organized under the laws of the Commonwealth of Massachusetts and the National
Municipals Fund is a corporation organized under the laws of the State of
Maryland. Each Fund maintains its principal place of business at Gateway Center
Three, Newark, New Jersey 07102. Shares of National Municipals Fund are divided
into four classes, designated Class A, Class B, Class C and Class Z. Shares of
Maryland Series and Michigan Series are divided into three classes, designated
Class A, Class B and Class C. Series Fund consists of thirteen series, two of
which are the Maryland Series and Michigan Series (collectively, the Series and
each individually, a Series).

 
    This Agreement is intended to be, and is adopted as, a plan of
reorganizations pursuant to Section 368(a)(1)(C) of the Internal Revenue Code of
1986, as amended (Internal Revenue Code). The reorganizations will comprise the
transfer of the assets of the Maryland Series and Michigan Series, respectively,
in exchange for shares of common stock of National Municipals Fund, and National
Municipals Fund's assumption of such Series' liabilities, if any, and the
constructive distribution, after the Closing Date hereinafter referred to, of
such shares of National Municipals Fund to the shareholders of the respective
Series, and the termination of the Series as provided herein, all upon the terms
and conditions as hereinafter set forth.
 
    In consideration of the premises and of the covenants and agreements set
forth herein, the parties covenant and agree as follows:
 
1.  TRANSFER OF ASSETS OF THE SERIES IN EXCHANGE FOR SHARES OF NATIONAL
    MUNICIPALS FUND AND ASSUMPTION OF LIABILITIES, IF ANY, AND TERMINATION OF
    THE SERIES
 
1.1  Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, Series Fund on behalf of
Maryland and Michigan Series agrees to sell, assign, transfer and deliver the
assets of each Series, as set forth in paragraph 1.2, to National Municipals
Fund, and National Municipals Fund agrees (a) to issue and deliver to each
Series in exchange therefor the number of shares of Class A Common Stock in
National Municipals Fund determined by dividing the net asset value of the
respective Series allocable to Class A, Class B and Class C shares of beneficial
interest (computed in the manner and as of the time and date set forth in
paragraph 2.1) by the net asset value allocable to a share of National
Municipals Fund Class A Common Stock (computed in the manner and as of the time
and date set forth in paragraph 2.2) and (b) to assume all of each Series'
liabilities, if any, as set forth in paragraph 1.3. Such transactions shall take
place at the closing provided for in paragraph 3 (Closing).
 
1.2  The assets of each Series to be acquired by National Municipals Fund shall
include without limitation all cash, cash equivalents, securities, receivables
(including interest and dividends receivable) and other property of any kind
owned by such Series and any deferred or prepaid expenses shown as assets on the
books of such Series on the closing date provided in paragraph 3 (Closing Date).
National Municipals Fund has no plan or intent to sell or otherwise dispose of
any assets of the Series, other than in the ordinary course of business.
 
                                     B-1(B)
<PAGE>
1.3  Except as otherwise provided herein, National Municipals Fund will assume
all debts, liabilities, obligations and duties of each Series of whatever kind
or nature, whether absolute, accrued, contingent or otherwise, whether or not
determinable as of the Closing Date and whether or not specifically referred to
in this Agreement; provided, however, that each Series agrees to utilize its
best efforts to cause such Series to discharge all of the known debts,
liabilities, obligations and duties of such Series prior to the Closing Date.
 
1.4  On or immediately prior to the Closing Date, each Series will declare and
pay to its shareholders of record dividends and/or other distributions so that
it will have distributed substantially all (and in any event not less than
ninety-eight percent) of each of such Series' investment company taxable income
(computed without regard to any deduction for dividends paid), net tax-exempt
interest income, if any, and realized net capital gains, if any, for all taxable
years through its termination.
 

1.5  On a date (Termination Date), as soon after the Closing Date as is
conveniently practicable, but in any event within 30 days of the Closing Date,
each Series will distribute PRO RATA to its Class A, Class B and Class C
shareholders of record, determined as of the close of business on the Closing
Date, the Class A shares of National Municipals Fund received by the Series
pursuant to paragraph 1.1 in exchange for their interest in such Series, and
Municipal Series Fund will file with the Secretary of State of The Commonwealth
of Massachusetts a Certificate of Termination terminating each Series. Such
distribution will be accomplished by opening accounts on the books of National
Municipals Fund in the names of each Series' shareholders and transferring
thereto the shares credited to the account of the respective Series on the books
of National Municipals Fund. Each account opened shall be credited with the
respective PRO RATA number of National Municipals Fund Class A shares due such
Series' Class A, Class B and Class C shareholders, respectively. Fractional
shares of National Municipals Fund shall be rounded to the third decimal place.

 
1.6  National Municipals Fund shall not issue certificates representing its
shares in connection with such exchange. With respect to any Series shareholder
holding Series receipts for shares of beneficial interest as of the Closing
Date, until National Municipals Fund is notified by Series Fund's transfer agent
that such shareholder has surrendered his or her outstanding Series receipts for
shares of beneficial interest or, in the event of lost, stolen or destroyed
receipts for shares of beneficial interest, posted adequate bond or submitted a
lost certificate form, as the case may be, National Municipals Fund will not
permit such shareholder to (1) receive dividends or other distributions on
National Municipals Fund shares in cash (although such dividends and
distributions shall be credited to the account of such shareholder established
on National Municipals Fund's books pursuant to paragraph 1.5, as provided in
the next sentence), (2) exchange National Municipals Fund shares credited to
such shareholder's account for shares of other Prudential Mutual Funds, or (3)
pledge or redeem such shares. In the event that a shareholder is not permitted
to receive dividends or other distributions on National Municipals Fund shares
in cash as provided in the preceding sentence, National Municipals Fund shall
pay such dividends or other distributions in additional National Municipals Fund
shares, notwithstanding any election such shareholder shall have made previously
with respect to the payment of dividends or other distributions on shares of the
Series. Each Series will, at its expense, request its shareholders to surrender
their outstanding Series receipts for shares of beneficial interest, post
adequate bond or submit a lost certificate form, as the case may be.
 
1.7  Ownership of National Municipals Fund shares will be shown on the books of
the National Municipals Fund's transfer agent. Shares of National Municipals
Fund will be issued in the manner described in National Municipals Fund's
then-current prospectus and statement of additional information.
 
                                     B-2(B)
<PAGE>
1.8  Any transfer taxes payable upon issuance of shares of National Municipals
Fund in exchange for shares of the Series in a name other than that of the
registered holder of the shares being exchanged on the books of that Series as
of that time shall be paid by the person to whom such shares are to be issued as
a condition to the registration of such transfer.
 
1.9  Any reporting responsibility with the Securities and Exchange Commission
(SEC) or any state securities commission of Series Fund with respect to a Series
is and shall remain the responsibility of the Series up to and including the
Termination Date.
 
1.10  All books and records of Series Fund, including all books and records
required to be maintained under the Investment Company Act of 1940, as amended
(Investment Company Act) and the rules and regulations thereunder, shall be
available to National Municipals Fund from and after the Closing Date and shall
be turned over to National Municipals Fund on or prior to the Termination Date.
 
2.  VALUATION
 
2.1  The value of each Series' assets and liabilities to be acquired and
assumed, respectively, by National Municipals Fund shall be the net asset value
computed as of 4:15 p.m., New York time, on the Closing Date (such time and date
being hereinafter called the Valuation Time), using the valuation procedures set
forth in such Series' then-current prospectus and Series Fund's statement of
additional information.
 
2.2  The net asset value of a share of National Municipals Fund shall be the net
asset value per such share computed on a class-by-class basis as of the
Valuation Time, using the valuation procedures set forth in National Municipals
Fund's then-current prospectus and statement of additional information.
 
2.3  The number of National Municipals Fund shares to be issued (including
fractional shares, if any) in exchange for the Series' net assets shall be
calculated as set forth in paragraph 1.1.
 
2.4  All computations of net asset value shall be made by or under the direction
of Prudential Investments Fund Management LLC (PIFM) in accordance with its
regular practice as manager of the Funds.
 
3.  CLOSING AND CLOSING DATE
 

3.1  The Closing Date shall be December 18, 1998 or such later date as the
parties may agree in writing. All acts taking place at the Closing shall be
deemed to take place simultaneously as of the close of business on the Closing
Date unless otherwise provided. The Closing shall be at the office of National
Municipals Fund or at such other place as the parties may agree.

 
3.2  State Street Bank and Trust Company (State Street), as custodian for each
Series, shall deliver to National Municipals Fund at the Closing a certificate
of an authorized officer of State Street stating that (a) the applicable Series'
portfolio securities, cash and any other assets have been transferred in proper
form to National Municipals Fund on the Closing Date and (b) all necessary
taxes, if any, have been paid, or provision for payment has been made, in
conjunction with the transfer of portfolio securities.
 
3.3  In the event that immediately prior to the Valuation Time (a) the New York
Stock Exchange (NYSE) or other primary exchange is closed to trading or trading
thereon is restricted or (b) trading or the reporting of trading on the NYSE or
other primary exchange or elsewhere is disrupted so that accurate appraisal of
the value of the net assets of the Series and of the net asset value per share
of National Municipals Fund is impracticable, the Closing Date shall be
postponed until the first business day after the date when such trading shall
have been fully resumed and such reporting shall have been restored.
 
                                     B-3(B)
<PAGE>
3.4  Series Fund shall deliver to National Municipals Fund on or prior to the
Termination Date the names and addresses of each of the shareholders of each
Series and the number of outstanding shares owned by each such shareholder, all
as of the close of business on the Closing Date, certified by the Secretary or
Assistant Secretary of Series Fund. National Municipals Fund shall issue and
deliver to Series Fund at the Closing a confirmation or other evidence
satisfactory to Series Fund that shares of National Municipals Fund have been or
will be credited to each Series' account on the books of National Municipals
Fund. At the Closing each party shall deliver to the other such bills of sale,
checks, assignments, share certificates, receipts and other documents as such
other party or its counsel may reasonably request to effect the transactions
contemplated by this Agreement.

C shares of the Fund and the Fund's assumption of all the liabilities, if 
any, of Intermediate Series (the "Reorganizations," and each a 
"Reorganization").  This opinion is furnished in connection with the Fund's 
Registration Statement on Form N-14 under the Securities Act of 1933, as 
amended (the "Registration Statement"), relating to Class A, Class B and 
Class C shares of common stock, par value $0.01 per share, of the Fund (the 
"Shares"), to be issued in the Reorganizations.

          As counsel for the Fund, we are familiar with the proceedings taken 
by it and to be taken by it in connection with the authorization, issuance 
and sale of the Shares.  In addition, we have examined and are familiar with 
the Articles of Incorporation of the Fund, as amended and supplemented, the 
By-Laws of the Fund, as amended, a certificate issued by the State Department 
of Assessments and Taxation of the State of Maryland, certifying the 
existence and good standing of the Fund, an opinion of Piper & Marbury, 
L.L.P., dated the date hereof, and attached as Annex A hereto and such other 
documents as we have deemed relevant to the matters referred to in this 
opinion.

          Based upon the foregoing, we are of the opinion that subsequent to 
the approval of each Agreement and Plan of Reorganization between the Fund 
and each of Series Fund and Bond Fund, respectively, set forth in the proxy 
statement and prospectus constituting a part of the Registration Statement 
(the "Proxy Statement and Prospectus"), the Shares, upon issuance in the 
manner referred to in the Registration Statement, for consideration not less 
than the par value thereof, will be legally issued, fully paid and 
non-assessable shares of common stock of the Fund.

    Re: Registration Statement on Form N-14
        -----------------------------------

Ladies and Gentlemen:

     We have acted as special Maryland counsel to Prudential National 
Municipals Fund, Inc. (the "Fund") in connection with the registration by the 
Fund of up to 750 million shares of its Common Stock divided into three 
classes, designated Class A, Class B and Class C shares (the "Shares"), 
pursuant to a registration statement on Form N-14, as amended (the 
"Registration Statement") under the Securities Act of 1933, as amended.

     In this capacity, we have examined the Fund's charter and by-laws, the 
proceedings of the Board of Directors of the Fund authorizing the issuance of 
the Shares in accordance with the Registration Statement, and such other 
statutes, certificates, instruments and documents relating to the Fund and 
matters of law as we have deemed necessary to the issuance of this opinion. 
In such examination, we have assumed the genuineness of all signatures, the 
conformity of final documents in all material respects to the versions 
thereof submitted to us in draft form, the authenticity of all documents 
submitted to us as originals, and the conformity with originals of all 
documents submitted to us as copies.

     Based upon the foregoing, and limited in all respects to applicable 
Maryland law, we are of the opinion and advise you that:

     1.  The Fund has been duly incorporated and is validly existing as a 
corporation under the laws of the State of Maryland.

<PAGE>

Prudential National Municipals Fund, Inc.

     2.  The Shares to be issued by the Fund pursuant to the Registration 
Statement have been duly authorized and, when issued as contemplated in the 
Registration Statement in an amount not to exceed the number of Shares 
authorized by the charter but unissued, will be legally issued, fully paid 
and nonassessable.

     Swidler Berlin Shereff Friedman, LLP are authorized to rely upon this 
opinion in rendering any opinion to the Fund which is to be filed as an 
exhibit to the Registration Statement. We hereby consent to the filing of 
this opinion as an exhibit to the Registration Statement.

                                 Very truly yours,

Dear Sirs:

     We are acting as counsel to Prudential National Municipals Fund, Inc., a 
Maryland corporation ("National Municipals Fund") and Prudential Municipal 
Bond Fund, a Massachusetts business trust ("Bond Fund") in connection with 
the proposed transfer of the assets of the Intermediate Series ("Intermediate 
Series") of Bond Fund to the National Municipals Fund and the assumption by 
National Municipals Fund of Intermediate Series' liabilities, if any, in 
exchange for shares of the National Municipals Fund (the "Shares") pursuant 
to an Agreement and Plan of Reorganization (the "Agreement").  The 
transactions contemplated by the Agreement are collectively referred to 
herein as the "Reorganization."

     We have participated in the preparation of the National Municipals 
Fund's Registration Statement on Form N-14 (the "Registration Statement") 
relating, among other things, to the Shares of National Municipals Fund to be 
offered in exchange for the assets and the assumption of the liabilities of 
Intermediate Series, and containing the Prospectus and Proxy Statement 
relating to the Reorganization (collectively, the "Prospectus"), filed with 
the Securities and Exchange Commission (the "Commission") pursuant to the 
provisions of the Securities Act of 1933, as amended (the "Securities Act"), 
and the rules and regulations of the Commission thereunder.  In addition, in 
connection with rendering the opinions expressed herein, we have examined 
originals or copies, certified or otherwise identified to our satisfaction, 
of such other documents, records and instruments as we have deemed necessary 
or appropriate for the purpose of rendering this opinion, including the form 
of the Agreement included as Appendix B to the Prospectus.

     In our examination of the foregoing documents, we have assumed the 
genuineness of all signatures, the authority of each signatory, the due 
execution and delivery of all documents by all

<PAGE>

Prudential National Municipals Fund, Inc. Prudential Municipal Bond Fund 
(Intermediate Series) September 18, 1998 Page 2

parties, the authenticity of all agreements, documents, certificates and 
instruments submitted to us as originals, the conformity of the Agreement as 
executed and delivered by the parties with the form of the Agreement 
contained in the Prospectus, and the conformity with originals of all 
agreements, documents, certificates and instruments submitted to us as copies.

     In rendering the opinions expressed herein, we have assumed that the 
transactions contemplated by the Agreement will be consummated in accordance 
therewith and as described in the Prospectus.  As to other questions of fact 
material to this opinion, we have assumed, with your approval and without 
independent investigation or verification, that the following facts will be 
accurate and complete as of the consummation of the Reorganization (the 
"Closing Date"). 

     1.   The fair market value of the Shares to be received by each 
Intermediate Series shareholder will be equal to the fair market value of the 
shares of beneficial interest of Intermediate Series surrendered in exchange 
therefor upon the liquidation of Intermediate Series.

     2.   There will be no plan or intention by any shareholder of 
Intermediate Series who owns 5 percent or more of Intermediate Series shares 
of beneficial interest, and to the best of the knowledge of management of 
Intermediate Series, there will be no plan or intention on the part of the 
remaining shareholders of Intermediate Series, to sell, exchange, or 
otherwise dispose of a number of Shares received in the Reorganization that 
would reduce Intermediate Series shareholders' ownership of Shares of 
National Municipals Fund to a number of Shares having a value, as of the 
Closing Date, of less than 50 percent of the value of all formerly 
outstanding shares of beneficial interest of Intermediate Series as of the 
same date.  For purposes hereof, shares of beneficial interest of 
Intermediate Series exchanged for cash or other property, surrendered by 
dissenters, or exchanged for cash in lieu of fractional Shares of National 
Municipals Fund will be treated as outstanding shares of beneficial interest 
of Intermediate Series at the Closing Date of the Reorganization.  Moreover, 
shares of beneficial interest of Intermediate Series and Shares of National 
Municipals Fund held by Intermediate Series shareholders and otherwise sold, 
redeemed, or disposed of prior or subsequent to the Reorganization and as 
part of the Reorganization will be considered in making this assumption.

     3.   Pursuant to the Agreement, Intermediate Series will distribute in 
complete liquidation of Intermediate Series, the Shares of National 
Municipals Fund received by Intermediate Series in the Reorganization.

     4.   The liabilities of Intermediate Series assumed by National 
Municipals Fund pursuant to the Reorganization, plus the liabilities, if any, 
to which assets transferred pursuant to the Reorganization will be subject, 
constitute less than 20% of the total consideration for the Reorganization, 
all such liabilities will have been incurred by Intermediate Series in the 
ordinary

<PAGE>

(Intermediate Series) September 18, 1998 Page 3

course of its business, and National Municipals Fund will pay no other 
consideration, except for the Shares, in connection with the Reorganization.

     5.   All expenses incurred by Intermediate Series with respect to the 
Reorganization will be borne by Intermediate Series.  Each shareholder of 
Intermediate Series will pay its respective share of the expenses, if any, 
incurred in connection with the Reorganization.  National Municipals Fund 
will pay the expenses, if any, incurred by it in connection with the 
Reorganization.

     6.   No intercorporate indebtedness will exist between National 
Municipals Fund and Intermediate Series that was issued, acquired, or will be 
settled at a discount.

     7.   Intermediate Series will not own, directly or indirectly, nor will 
it have owned during the  five years preceding the Closing Date, directly or 
indirectly, any stock of National Municipals Fund.

     8.   The assets of Intermediate Series transferred to National 
Municipals Fund will include all assets owned by Intermediate Series at fair 
market value on the Closing Date subject to all known liabilities of 
Intermediate Series at such time.

     9.   In accordance with the terms of the Agreement, Intermediate Series 
will transfer all of its business and will transfer assets to National 
Municipals Fund representing at least 90% of the fair market value of the net 
assets, and at least 70% of the fair market value of the gross assets, held 
by Intermediate Series immediately prior to the Reorganization.  For purposes 
of this assumption, amounts paid by Intermediate Series to shareholders who 
receive cash or other property, amounts paid to dissenters, amounts used by 
Intermediate Series to pay its reorganization expenses and all redemptions 
and distributions (other than regular, normal redemptions and dividends) made 
by Intermediate Series immediately preceding the Reorganization will be 
included as assets of Intermediate Series held immediately prior to the 
Reorganization.

     10.  The fair market value of the assets of Intermediate Series 
transferred to National Municipals Fund will equal or exceed the sum of 
liabilities assumed by National Municipals Fund, plus the amount of 
liabilities, if any, to which the transferred assets will be subject.

     11.  Intermediate Series will not be under the jurisdiction of a court 
in a Title 11 or similar case within the meaning of Section 368(a)(3)(A) of 
the Internal Revenue Code of 1986, as amended (the "Code").

<PAGE>

     12.  No cash will be paid to the shareholders of Intermediate Series in
lieu of fractional Shares.

     13.  For federal income tax purposes, Intermediate Series will qualify 
as a regulated investment company (as defined in Code Section 851) and will 
have so qualified since its formation.  The provisions of Code Sections 851 
through 855 apply to Intermediate Series and will continue to apply through 
the Closing Date.

     14.  As of the Closing Date, Intermediate Series will have declared to 
its shareholders of record a dividend or dividends payable prior to closing, 
which together with all previous such dividends will have the effect of 
distributing all of Intermediate Series' investment company taxable income 
plus the excess of its interest income, if any, excludable from gross income 
under Code Section 103(a) (including by virtue of prior Section 853(b)(5)(C) 
of the Code) over its deductions disallowed under Sections 265 and 171(a)(2) 
for the taxable year of Intermediate Series ending on the Closing Date and 
all its net capital gain realized in such taxable year.

     15.  Except to the extent necessary to comply with its legal obligation 
to redeem its own shares, National Municipals Fund will have no plan or 
intention to reacquire any of the Shares issued in the Reorganization.

     16.  Aside from an initial realignment of the portfolio of Intermediate 
Series in which National Municipals Fund will dispose of no more than 66 2/3% 
of Intermediate Series' assets acquired in the Reorganization, National 
Municipals Fund will have no plan or intention to sell or otherwise dispose 
of any of the assets of the Intermediate Series acquired in the 
Reorganization, other than dispositions made in the ordinary course of 
business.

     17.  Following the Reorganization, National Municipals Fund will 
continue the historic business of Intermediate Series or use a significant 
portion of Intermediate Series' historic business assets in its business.

     18.  National Municipals Fund will not own, directly or indirectly, nor 
will it have owned during the five years preceding the Closing Date, directly 
or indirectly, any shares of beneficial interest of Intermediate Series.

     19.  National Municipals Fund will not be under the jurisdiction of a 
court in a Title 11 or similar case within the meaning of Code Section 
368(a)(3)(A).

     20.  For federal income tax purposes, National Municipals Fund will 
qualify as a regulated investment company (as defined in Code Section 851) 
and will have so qualified since

<PAGE>

Prudential National Municipals Fund, Inc.
Prudential Municipal Bond Fund (Intermediate Series)

Page 5

its formation.  The provisions of Code Sections 851 through 855 apply to 
National Municipals Fund prior to the Reorganization and will continue to 
apply after the Closing Date.

     21.  No compensation received by any shareholder-employee of 
Intermediate Series will be separate consideration for the Reorganization; 
none of the Shares of National Municipals Fund received by any 
shareholder-employee will be separate consideration for, or allocable to, any 
employment agreement; and any compensation paid to any shareholder-employee 
will be for services actually rendered and will be commensurate with amounts 
paid to other parties bargaining at arm's length for similar services.

     We note that we are members of the Bar of the State of New York and that 
our opinion is expressly limited to the federal laws of the United States.

     Based on the foregoing and subject to the assumptions and limitations 
set forth above and such examination of law as we have deemed necessary, we 
are of the opinion that:

     1.   The Reorganization will constitute a reorganization within the meaning
          of Section 368(a)(1)(C) of the Code;

     2.   Intermediate Series and National Municipals Fund will each be a "party
          to a reorganization" within the meaning of Section 368(b) of the Code;

     3.   Pursuant to Sections 361(a) and 357(a) of the Code, no gain or loss
          will be recognized by Intermediate Series upon the transfer of its
          assets to National Municipals Fund in exchange solely for Shares of
          National Municipals Fund as a result of the Reorganization and the
          assumption by National Municipals Fund of Intermediate Series'
          liabilities, if any, or upon the distribution (whether actual or
          constructive) of the Shares of National Municipals Fund in complete
          liquidation of Intermediate Series;

     4.   Pursuant to Section 1032(a) of the Code, no gain or loss will be
          recognized by National Municipals Fund upon its acquisition of
          Intermediate Series' assets solely in exchange for Shares of  National
          Municipals Fund and the assumption by National Municipals Fund of the
          liabilities of Intermediate Series;

     5.   Pursuant to Section 362(b) of the Code, the basis of the assets of
          Intermediate Series acquired by  National Municipals Fund will be the
          same as the basis of such assets when held by Intermediate Series
          immediately prior to the Reorganization;

     6.   Pursuant to Section 1223(2) of the Code, the holding period of the
          assets of Intermediate Series acquired by National Municipals Fund
          will include the period during which such assets were held by
          Intermediate Series;

     7.   Pursuant to Section 354(a)(1) of the Code, no gain or loss will be
          recognized by a shareholder of Intermediate Series upon the exchange
          of his or her shares of beneficial interest solely for Shares of
          National Municipals Fund, including fractional Shares, in liquidation
          of Intermediate Series;

     8.   Pursuant to Section 358(a)(1) of the Code, the basis of the Shares of
          National Municipals Fund received by former Intermediate Series
          shareholders will be the same as the basis of Intermediate Series
          shares of beneficial interest surrendered in exchange therefor; and

     9.   Pursuant to Section 1223(1) of the Code, the holding period for Shares
          of National Municipals Fund received by each shareholder of
          Intermediate Series in exchange for his or her shares of beneficial
          interest of Intermediate Series will include the period during which
          such shareholder held shares of beneficial interest of Intermediate
          Series (provided Intermediate Series shares of beneficial interest
          were held as capital assets on the date of the exchange).

     The opinions expressed herein are based upon currently applicable 
statutes and regulations and existing judicial and administrative 
interpretations.  We can provide no assurance that such statutes or 
regulations, or existing judicial or administrative interpretations thereof, 
will not be amended, revoked or modified (possibly prior to the Closing Date) 
in a manner which would affect any of our conclusions.  Finally, we note that 
this opinion is solely for the benefit of the addressees hereof in connection 
with the transaction described herein and, except as otherwise provided 
herein, should not be referred to, used, relied upon or quoted (with or 
without specific reference to our firm) in any documents, reports, financial

Dear Sirs:

     We are acting as counsel to Prudential National Municipals Fund, Inc., a 
Maryland corporation ("National Municipals Fund") and Prudential Municipal 
Series Fund, a Massachusetts business trust ("Series Fund") in connection 
with the proposed transfer of the assets of the Michigan Series ("Michigan 
Series") of Series Fund to the National Municipals Fund and the assumption by 
National Municipals Fund of Michigan Series' liabilities, if any, in exchange 
for Class A shares of the National Municipals Fund (the "Shares") pursuant to 
an Agreement and Plan of Reorganization (the "Agreement").  The transactions 
contemplated by the Agreement are collectively referred to herein as the 
"Reorganization."

     We have participated in the preparation of the National Municipals 
Fund's Registration Statement on Form N-14 (the "Registration Statement") 
relating, among other things, to the Shares of National Municipals Fund to be 
offered in exchange for the assets and the assumption of the liabilities of 
Michigan Series, and containing the Prospectus and Proxy Statement relating 
to the Reorganization (collectively, the "Prospectus"), filed with the 
Securities and Exchange Commission (the "Commission") pursuant to the 
provisions of the Securities Act of 1933, as amended (the "Securities Act"), 
and the rules and regulations of the Commission thereunder.  In addition, in 
connection with rendering the opinions expressed herein, we have examined 
originals or copies, certified or otherwise identified to our satisfaction, 
of such other documents, records and instruments as we have deemed necessary 
or appropriate for the purpose of rendering this opinion, including the form 
of the Agreement included as Appendix B to the Prospectus.

     In our examination of the foregoing documents we have assumed the 
genuineness of all signatures, the authority of each signatory, the due 
execution and delivery of all documents by all parties, the authenticity of 
all agreements, documents, certificates and instruments submitted to

<PAGE>

Prudential National Municipals Fund, Inc.

us as originals, the conformity of the Agreement as executed and delivered by 
the parties with the form of the Agreement contained in the Prospectus, and 
the conformity with originals of all agreements, documents, certificates and 
instruments submitted to us as copies.

     In rendering the opinions expressed herein, we have assumed that the 
transactions contemplated by the Agreement will be consummated in accordance 
therewith and as described in the Prospectus.  As to other questions of fact 
material to this opinion, we have assumed, with your approval and without 
independent investigation or verification, that the following facts will be 
accurate and complete as of the consummation of the Reorganization (the 
"Closing Date"). 

     1.   The fair market value of the Shares to be received by each Michigan 
Series shareholder will be equal to the fair market value of the shares of 
beneficial interest of Michigan Series surrendered in exchange therefor upon 
the liquidation of Michigan Series.

     2.   There will be no plan or intention by any shareholder of Michigan 
Series who owns 5 percent or more of Michigan Series shares of beneficial 
interest, and to the best of the knowledge of management of Michigan Series, 
there will be no plan or intention on the part of the remaining shareholders 
of Michigan Series, to sell, exchange, or otherwise dispose of a number of 
Shares received in the Reorganization that would reduce Michigan Series 
shareholders' ownership of Shares of National Municipals Fund to a number of 
Shares having a value, as of the Closing Date, of less than 50 percent of the 
value of all formerly outstanding shares of beneficial interest of Michigan 
Series as of the same date.  For purposes hereof, shares of beneficial 
interest of Michigan Series exchanged for cash or other property, surrendered 
by dissenters, or exchanged for cash in lieu of fractional Shares of National 
Municipals Fund will be treated as outstanding shares of beneficial interest 
of Michigan Series at the Closing Date of the Reorganization.  Moreover, 
shares of beneficial interest of Michigan Series and Shares of National 
Municipals Fund held by Michigan Series shareholders and otherwise sold, 
redeemed, or disposed of prior or subsequent to the Reorganization and as 
part of the Reorganization will be considered in making this assumption.

     3.   Pursuant to the Agreement, Michigan Series will distribute in 
complete liquidation of Michigan Series, the Shares of National Municipals 
Fund received by Michigan Series in the Reorganization.

     4.   The liabilities of Michigan Series assumed by National Municipals 
Fund pursuant to the Reorganization, plus the liabilities, if any, to which 
assets transferred pursuant to the Reorganization will be subject, constitute 
less than 20% of the total consideration for the Reorganization, all such 
liabilities will have been incurred by Michigan Series in the ordinary course 
of its business, and National Municipals Fund will pay no other 
consideration, except for

<PAGE>

Prudential National Municipals Fund, Inc.

the Shares, in connection with the Reorganization.

     5.   All expenses incurred by Michigan Series with respect to the 
Reorganization will be borne by Michigan Series.  Each shareholder of 
Michigan Series will pay its respective share of the expenses, if any, 
incurred in connection with the Reorganization.  National Municipals Fund 
will pay the expenses, if any, incurred by it in connection with the 
Reorganization.

     6.   No intercorporate indebtedness will exist between National 
Municipals Fund and Michigan Series that was issued, acquired, or will be 
settled at a discount.

     7.   Michigan Series will not own, directly or indirectly, nor will it 
have owned during the  five years preceding the Closing Date, directly or 
indirectly, any stock of National Municipals Fund.

     8.   The assets of Michigan Series transferred to National Municipals 
Fund will include all assets owned by Michigan Series at fair market value on 
the Closing Date subject to all known liabilities of Michigan Series at such 
time.

     9.   In accordance with the terms of the Agreement, Michigan Series will 
transfer all of its business and will transfer assets to National Municipals 
Fund representing at least 90% of the fair market value of the net assets, 
and at least 70% of the fair market value of the gross assets, held by 
Michigan Series immediately prior to the Reorganization.  For purposes of 
this assumption, amounts paid by Michigan Series to shareholders who receive 
cash or other property, amounts paid to dissenters, amounts used by Michigan 
Series to pay its reorganization expenses and all redemptions and 
distributions (other than regular, normal redemptions and dividends) made by 
Michigan Series immediately preceding the Reorganization will be included as 
assets of Michigan Series held immediately prior to the Reorganization.

     10.  The fair market value of the assets of Michigan Series transferred 
to National Municipals Fund will equal or exceed the sum of liabilities 
assumed by National Municipals Fund, plus the amount of liabilities, if any, 
to which the transferred assets will be subject.

     11.  Michigan Series will not be under the jurisdiction of a court in a 
Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the 
Internal Revenue Code of 1986, as amended (the "Code").

fractional Shares.

     13.  For federal income tax purposes, Michigan Series will qualify as a 
regulated investment company (as defined in Code Section 851) and will have 
so qualified since its formation.  The provisions of Code Sections 851 
through 855 apply to Michigan Series and will continue to apply through the 
Closing Date.

     14.  As of the Closing Date, Michigan Series will have declared to its 
shareholders of record a dividend or dividends payable prior to closing, 
which together with all previous such dividends will have the effect of 
distributing all of Michigan Series' investment company taxable income plus 
the excess of its interest income, if any, excludable from gross income under 
Code Section 103(a) (including by virtue of prior Section 853(b)(5)(C) of the 
Code) over its deductions disallowed under Sections 265 and 171(a)(2) for the 
taxable year of Michigan Series ending on the Closing Date and all its net 
capital gain realized in such taxable year.

     15.  Except to the extent necessary to comply with its legal obligation 
to redeem its own shares, National Municipals Fund will have no plan or 
intention to reacquire any of the Shares issued in the Reorganization.

     16.  Aside from an initial realignment of the portfolio of Michigan 
Series in which National Municipals Fund will dispose of no more than 66 2/3% 
of Michigan Series' assets acquired in the Reorganization, National 
Municipals Fund will have no plan or intention to sell or otherwise dispose 
of any of the assets of the Michigan Series acquired in the Reorganization, 
other than dispositions made in the ordinary course of business.

     17.  Following the Reorganization, National Municipals Fund will 
continue the historic business of Michigan Series or use a significant 
portion of Michigan Series' historic business assets in its business.

     18.  National Municipals Fund will not own, directly or indirectly, nor 
will it have owned during the five years preceding the Closing Date, directly 
or indirectly, any shares of beneficial interest of Michigan Series.

     19.  National Municipals Fund will not be under the jurisdiction of a 
court in a Title 11 or similar case within the meaning of Code Section 
368(a)(3)(A).

     20.  For federal income tax purposes, National Municipals Fund will 
qualify as a regulated investment company (as defined in Code Section 851) 
and will have so qualified since its formation.  The provisions of Code 
Sections 851 through 855 apply to National Municipals Fund prior to the 
Reorganization and will continue to apply after the Closing Date.

     21.  No compensation received by any shareholder-employee of Michigan 
Series will be separate consideration for the Reorganization; none of the 
Shares of National Municipals Fund received by any shareholder-employee will 
be separate consideration for, or allocable to, any employment agreement; and 
any compensation paid to any shareholder-employee will be for services 
actually rendered and will be commensurate with amounts paid to other parties 
bargaining at arm's length for similar services.

     We note that we are members of the Bar of the State of New York and that 
our opinion is expressly limited to the federal laws of the United States.

     Based on the foregoing and subject to the assumptions and limitations 
set forth above and such examination of law as we have deemed necessary, we 
are of the opinion that:

     1.   The Reorganization will constitute a reorganization within the meaning
          of Section 368(a)(1)(C) of the Code;

     2.   Michigan Series and National Municipals Fund will each be a "party to
          a reorganization" within the meaning of Section 368(b) of the Code;

     3.   Pursuant to Sections 361(a) and 357(a) of the Code, no gain or loss
          will be recognized by Michigan Series upon the transfer of its assets
          to National Municipals Fund in exchange solely for Shares of National
          Municipals Fund as a result of the Reorganization and the assumption
          by National Municipals Fund of Michigan Series' liabilities, if any,
          or upon the distribution (whether actual or constructive) of the
          Shares of National Municipals Fund in complete liquidation of Michigan
          Series;

     4.   Pursuant to Section 1032(a) of the Code, no gain or loss will be
          recognized by National Municipals Fund upon its acquisition of
          Michigan Series' assets solely in exchange for Shares of  National
          Municipals Fund and the assumption by National Municipals Fund of the
          liabilities of Michigan Series;

     5.   Pursuant to Section 362(b) of the Code, the basis of the assets of
          Michigan Series acquired by National Municipals Fund will be the same
          as the basis of such assets when held by Michigan Series immediately
          prior to the Reorganization;

     6.   Pursuant to Section 1223(2) of the Code, the holding period of the
          assets of Michigan Series acquired by National Municipals Fund will
          include the period during which such assets were held by Michigan
          Series;

     7.   Pursuant to Section 354(a)(1) of the Code, no gain or loss will be
          recognized by a shareholder of Michigan Series upon the exchange of
          his or her shares of beneficial interest solely for Shares of National
          Municipals Fund, including fractional Shares, in liquidation of
          Michigan Series;

     8.   Pursuant to Section 358(a)(1) of the Code, the basis of the Shares of
          National Municipals Fund received by former Michigan Series
          shareholders will be the same as the basis of Michigan Series shares
          of beneficial interest surrendered in exchange therefor; and

     9.   Pursuant to Section 1223(1) of the Code, the holding period for Shares
          of National Municipals Fund received by each shareholder of Michigan
          Series in exchange for his or her shares of beneficial interest of
          Michigan Series will include the period during which such shareholder
          held shares of beneficial interest of Michigan Series (provided
          Michigan Series shares of beneficial interest were held as capital
          assets on the date of the exchange).
     
     The opinions expressed herein are based upon currently applicable 
statutes and regulations and existing judicial and administrative 
interpretations.  We can provide no assurance that such statutes or 
regulations, or existing judicial or administrative interpretations thereof, 
will not be amended, revoked or modified (possibly prior to the Closing Date) 
in a manner which would affect any of our conclusions.  Finally, we note that 
this opinion is solely for the benefit of the addressees hereof in connection

Dear Sirs:

     We are acting as counsel to Prudential National Municipals Fund, Inc., a 
Maryland corporation ("National Municipals Fund") and Prudential Municipal 
Series Fund, a Massachusetts business trust ("Series Fund") in connection 
with the proposed transfer of the assets of the Maryland Series ("Maryland 
Series") of Series Fund to the National Municipals Fund and the assumption by 
National Municipals Fund of Maryland Series' liabilities, if any, in exchange 
for Class A shares of the National Municipals Fund (the "Shares") pursuant to 
an Agreement and Plan of Reorganization (the "Agreement").  The transactions 
contemplated by the Agreement are collectively referred to herein as the 
"Reorganization."

     We have participated in the preparation of the National Municipals 
Fund's Registration Statement on Form N-14 (the "Registration Statement") 
relating, among other things, to the Shares of National Municipals Fund to be 
offered in exchange for the assets and the assumption of the liabilities of 
Maryland Series, and containing the Prospectus and Proxy Statement relating 
to the Reorganization (collectively, the "Prospectus"), filed with the 
Securities and Exchange Commission (the "Commission") pursuant to the 
provisions of the Securities Act of 1933, as amended (the "Securities Act"), 
and the rules and regulations of the Commission thereunder.  In addition, in 
connection with rendering the opinions expressed herein, we have examined 
originals or copies, certified or otherwise identified to our satisfaction, 
of such other documents, records and instruments as we have deemed necessary 
or appropriate for the purpose of rendering this opinion, including the form 
of the Agreement included as Appendix B to the Prospectus.

     In our examination of the foregoing documents, we have assumed the 
genuineness of all signatures, the authority of each signatory, the due 
execution and delivery of all documents by all parties, the authenticity of 
all agreements, documents, certificates and instruments submitted to

<PAGE>

Prudential National Municipals Fund, Inc.
Prudential Municipal Series Fund (Maryland Series)

Page 2

us as originals, the conformity of the Agreement as executed and delivered by 
the parties with the form of the Agreement contained in the Prospectus, and 
the conformity with originals of all agreements, documents, certificates and 
instruments submitted to us as copies.

     In rendering the opinions expressed herein, we have assumed that the 
transactions contemplated by the Agreement will be consummated in accordance 
therewith and as described in the Prospectus.  As to other questions of fact 
material to this opinion, we have assumed, with your approval and without 
independent investigation or verification, that the following facts will be 
accurate and complete as of the consummation of the Reorganization (the 
"Closing Date"). 

     1.   The fair market value of the Shares to be received by each Maryland 
Series shareholder will be equal to the fair market value of the shares of 
beneficial interest of Maryland Series surrendered in exchange therefor upon 
the liquidation of Maryland Series.

     2.   There will be no plan or intention by any shareholder of Maryland 
Series who owns 5 percent or more of Maryland Series shares of beneficial 
interest, and to the best of the knowledge of management of Maryland Series, 
there will be no plan or intention on the part of the remaining shareholders 
of Maryland Series, to sell, exchange, or otherwise dispose of a number of 
Shares received in the Reorganization that would reduce Maryland Series 
shareholders' ownership of Shares of National Municipals Fund to a number of 
Shares having a value, as of the Closing Date, of less than 50 percent of the 
value of all formerly outstanding shares of beneficial interest of Maryland 
Series as of the same date.  For purposes hereof, shares of beneficial 
interest of Maryland Series exchanged for cash or other property, surrendered 
by dissenters, or exchanged for cash in lieu of fractional Shares of National 
Municipals Fund will be treated as outstanding shares of beneficial interest 
of Maryland Series at the Closing Date of the Reorganization.  Moreover, 
shares of beneficial interest of Maryland Series and Shares of National 
Municipals Fund held by Maryland Series shareholders and otherwise sold, 
redeemed, or disposed of prior or subsequent to the Reorganization and as 
part of the Reorganization will be considered in making this assumption.

     3.   Pursuant to the Agreement, Maryland Series will distribute in 
complete liquidation of Maryland Series, the Shares of National Municipals 
Fund received by Maryland Series in the Reorganization.

     4.   The liabilities of Maryland Series assumed by National Municipals 
Fund pursuant to the Reorganization, plus the liabilities, if any, to which 
assets transferred pursuant to the Reorganization will be subject, constitute 
less than 20% of the total consideration for the Reorganization, all such 
liabilities will have been incurred by Maryland Series in the ordinary course 
of its business, and National Municipals Fund will pay no other 
consideration, except for

Page 3

the Shares, in connection with the Reorganization.

     5.   All expenses incurred by Maryland Series with respect to the 
Reorganization will be borne by Maryland Series.  Each shareholder of 
Maryland Series will pay its respective share of the expenses, if any, 
incurred in connection with the Reorganization.  National Municipals Fund 
will pay the expenses, if any, incurred by it in connection with the 
Reorganization.

     6.   No intercorporate indebtedness will exist between National 
Municipals Fund and Maryland Series that was issued, acquired, or will be 
settled at a discount.

     7.   Maryland Series will not own, directly or indirectly, nor will it 
have owned during the five years preceding the Closing Date, directly or 
indirectly, any stock of National Municipals Fund.

     8.   The assets of Maryland Series transferred to National Municipals 
Fund will include all assets owned by Maryland Series at fair market value on 
the Closing Date subject to all known liabilities of Maryland Series at such 
time.

     9.   In accordance with the terms of the Agreement, Maryland Series will 
transfer all of its business and will transfer assets to National Municipals 
Fund representing at least 90% of the fair market value of the net assets, 
and at least 70% of the fair market value of the gross assets, held by 
Maryland Series immediately prior to the Reorganization.  For purposes of 
this assumption, amounts paid by Maryland Series to shareholders who receive 
cash or other property, amounts paid to dissenters, amounts used by Maryland 
Series to pay its reorganization expenses and all redemptions and 
distributions (other than regular, normal redemptions and dividends) made by 
Maryland Series immediately preceding the Reorganization will be included as 
assets of Maryland Series held immediately prior to the Reorganization.

     10.  The fair market value of the assets of Maryland Series transferred 
to National Municipals Fund will equal or exceed the sum of liabilities 
assumed by National Municipals Fund, plus the amount of liabilities, if any, 
to which the transferred assets will be subject.

     11.  Maryland Series will not be under the jurisdiction of a court in a 
Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the 
Internal Revenue Code of 1986, as amended (the "Code").

     12.  No cash will be paid to the shareholders of Maryland Series in lieu 
of fractional Shares.

     13.  For federal income tax purposes, Maryland Series will qualify as a 
regulated investment company (as defined in Code Section 851) and will have 
so qualified since its formation.  The provisions of Code Sections 851 
through 855 apply to Maryland Series and will continue to apply through the 
Closing Date.

     14.  As of the Closing Date, Maryland Series will have declared to its 
shareholders of record a dividend or dividends payable prior to closing, 
which together with all previous such dividends will have the effect of 
distributing all of Maryland Series' investment company taxable income plus 
the excess of its interest income, if any, excludable from gross income under 
Code Section 103(a) (including by virtue of prior Section 853(b)(5)(C) of the 
Code) over its deductions disallowed under Sections 265 and 171(a)(2) for the 
taxable year of Maryland Series ending on the Closing Date and all its net 
capital gain realized in such taxable year.

     15.  Except to the extent necessary to comply with its legal obligation 
to redeem its own shares, National Municipals Fund will have no plan or 
intention to reacquire any of the Shares issued in the Reorganization.

     16.  Aside from an initial realignment of the portfolio of Maryland 
Series in which National Municipals Fund will dispose of no more than 66 2/3% 
of Maryland Series' assets acquired in the Reorganization, National 
Municipals Fund will have no plan or intention to sell or otherwise dispose 
of any of the assets of the Maryland Series acquired in the Reorganization, 
other than dispositions made in the ordinary course of business.

     17.  Following the Reorganization, National Municipals Fund will 
continue the historic business of Maryland Series or use a significant 
portion of Maryland Series' historic business assets in its business.

     18.  National Municipals Fund will not own, directly or indirectly, nor 
will it have owned during the five years preceding the Closing Date, directly 
or indirectly, any shares of beneficial interest of Maryland Series.

     19.  National Municipals Fund will not be under the jurisdiction of a 
court in a Title 11 or similar case within the meaning of Code Section 
368(a)(3)(A).

     20.  For federal income tax purposes, National Municipals Fund will 
qualify as a regulated investment company (as defined in Code Section 851) 
and will have so qualified since its formation.  The provisions of Code 
Sections 851 through 855 apply to National Municipals Fund prior to the 
Reorganization and will continue to apply after the Closing Date.

     21.  No compensation received by any shareholder-employee of Maryland 
Series will be separate consideration for the Reorganization; none of the 
Shares of National Municipals Fund received by any shareholder-employee will 
be separate consideration for, or allocable to, any employment agreement; and 
any compensation paid to any shareholder-employee will be for services 
actually rendered and will be commensurate with amounts paid to other parties 
bargaining at arm's length for similar services.

     We note that we are members of the Bar of the State of New York and that 
our opinion is expressly limited to the federal laws of the United States.

     Based on the foregoing and subject to the assumptions and limitations 
set forth above and such examination of law as we have deemed necessary, we 
are of the opinion that:

     1.   The Reorganization will constitute a reorganization within the 
          meaning of Section 368(a)(1)(C) of the Code;

     2.   Maryland Series and National Municipals Fund will each be a "party to
          a reorganization" within the meaning of Section 368(b) of the Code;

     3.   Pursuant to Sections 361(a) and 357(a) of the Code, no gain or loss
          will be recognized by Maryland Series upon the transfer of its assets
          to National Municipals Fund in exchange solely for Shares of National
          Municipals Fund as a result of the Reorganization and the assumption
          by National Municipals Fund of Maryland Series' liabilities, if any,
          or upon the distribution (whether actual or constructive) of the
          Shares of National Municipals Fund in complete liquidation of Maryland
          Series;

     4.   Pursuant to Section 1032(a) of the Code, no gain or loss will be
          recognized by National Municipals Fund upon its acquisition of
          Maryland Series' assets solely in exchange for Shares of National
          Municipals Fund and the assumption by National Municipals Fund of the
          liabilities of Maryland Series;

     5.   Pursuant to Section 362(b) of the Code, the basis of the assets of
          Maryland Series acquired by National Municipals Fund will be the same
          as the basis of such assets when held by Maryland Series immediately
          prior to the Reorganization;

     6.   Pursuant to Section 1223(2) of the Code, the holding period of the
          assets of Maryland Series acquired by National Municipals Fund will
          include the period during which such assets were held by Maryland
          Series;

     7.   Pursuant to Section 354(a)(1) of the Code, no gain or loss will be
          recognized by a shareholder of Maryland Series upon the exchange of
          his or her shares of beneficial interest solely for Shares of National
          Municipals Fund, including fractional Shares, in liquidation of
          Maryland Series;

     8.   Pursuant to Section 358(a)(1) of the Code, the basis of the Shares of
          National Municipals Fund received by former Maryland Series
          shareholders will be the same as the basis of Maryland Series shares
          of beneficial interest surrendered in exchange therefor; and

     9.   Pursuant to Section 1223(1) of the Code, the holding period for Shares
          of National Municipals Fund received by each shareholder of Maryland
          Series in exchange for his or her shares of beneficial interest of
          Maryland Series will include the period during which such shareholder
          held shares of beneficial interest of Maryland Series (provided
          Maryland Series shares of beneficial interest were held as capital
          assets on the date of the exchange).

for or reimbursed by the Fund. 
 
  The following information supplements "How the Fund Values its Shares" in 
the Retail Class Prospectus: 
 
  Although the legal rights of each class of shares are substantially 
identical, the different expenses borne by each class will result in 
different dividends. As long as the Fund declares dividends daily, the NAV of 
the Class A, Class B, Class C and Class Z shares will generally be the same. 
It is expected, however, that the Fund's dividends will differ by 
approximately the amount of any distribution and/or service fee expense 
accrual differential among the classes. 
 
  The following information supplements "Taxes, Dividends and 
Distributions-Dividends and Distributions" in the Retail Class Prospectus: 
 
  The per share dividends on Class Z shares will generally be higher than the 
per share dividends on Class A, Class B or Class C shares as a result of the 
fact that Class Z shares are not subject to any distribution or service fee. 
 
  The following information supplements "Shareholder Guide-How to Buy Shares 
of the Fund" and "Shareholder Guide-How to Sell Your Shares" in the Retail 
Class Prospectus: 
 
  Class Z shares of the Fund are currently available for purchase by the 
following categories of investors: 
 
  (i) participants in any fee-based program or trust program sponsored by any 
affiliate of the Distributor which includes mutual funds as investment 
options and for which the Fund is an available option; (ii) current and 
former Directors/Trustees of the Prudential Mutual Funds (including the 
Fund); and (iii) employees of Prudential or Prudential Securities who 
participate in an employer-sponsored employee saving plan. 
 
  In connection with the sale of Class Z shares, the Manager, the Distributor 
or one of their affiliates may pay brokers or dealers that have entered into 
agreements to act as participating or introducing brokers for the Distributor 
(Dealers), financial advisers and other persons which distribute shares a 
finders' fee, based on a percentage of the NAV of shares sold by such 
persons. 
 
  The following information supplements "Shareholder Guide-How to Exchange 
Your Shares" in the Retail Class Prospectus: 
 
  Class Z shareholders of the Fund may exchange their Class Z shares for 
Class Z shares of other Prudential Mutual Funds on the basis of relative net 
asset value. Shareholders who qualify to purchase Class Z shares (other than 
participants in any fee-based program) will have their Class B and Class C 
shares which are not subject to contingent deferred sales charges and their 
Class A shares exchanged for Class Z shares on a quarterly basis. 
Participants in any fee-based program for which the Fund is an available 
option will have their Class A shares, if any, exchanged for Class Z shares 
when they elect to have those assets become a part of the fee-based program. 
Upon leaving the program (whether voluntary or not), such Class Z shares 
(and, to the extent provided for in the program, Class Z shares acquired 
through participation in the program) will be exchanged for Class A shares at 
the net asset value. See "Shareholder Guide-How to Exchange Your 
Shares-Special Exchange Privileges." 
 
  The information above also supplements the information under "Fund 
Highlights" in the Retail Class Prospectus as appropriate.

  The following information supplements "Fund Expenses" and "Shareholder 
Guide": 
 
New Pricing Structure for Class C Shares
 
  Effective on November 2, 1998, Class C shares of the Prudential Mutual 
Funds will be sold with a 1% initial sales charge and will be subject to a 
contingent deferred sales charge of 1% of the lesser of the amount invested 
or the redemption proceeds if redeemed within 18 months of purchase. In 
connection with the sale of Class C shares, the Distributor will pay dealers, 
financial advisers and other persons who sell Class C shares a sales 
commission of up to 2% of the purchase price at the time of sale. 
 
  Class C shares issued before November 2, 1998 will not be affected by the 
new pricing structure described above and will continue to be subject to a 
contingent deferred sales charge of 1% on redemptions within one year of 
purchase. 
 
Waiver of Initial Sales Charge-Class A Shares
 
  The paragraph under "Alternative Purchase Plan-Class A Shares-Reduction and 
Waiver of Initial Sales Charges-Benefit Plans" is amended to read in its 
entirety as follows: 
 
  Benefit Plans. Class A shares may be purchased at NAV, without payment of 
an initial sales charge, by pension, profit-sharing or other employee benefit 
plans qualified under Section 401 of the Internal Revenue Code, deferred 
compensation and annuity plans under Sections 457 and 403 (b)(7) of the 
Internal Revenue Code and non-qualified deferred compensation plans that are 
sponsored by any employer that has a tax qualified benefit plan with 
Prudential (collectively, Benefit Plans), provided that the Benefit Plan has 
existing assets of at least $1 million invested in shares of Prudential 
Mutual Funds (excluding money market funds other than those acquired pursuant 
to the exchange privilege) or 250 eligible employees or participants. In the 
case of Benefit Plans whose accounts are held directly with the Transfer 
Agent or Prudential Securities and for which the Transfer Agent or Prudential 
Securities does individual account recordkeeping (Direct Account Benefit 
Plans) and Benefit Plans sponsored by Prudential, Prudential Securities or 
its subsidiaries (Prudential Securities or Subsidiary Prototype Benefit 
Plans), Class A shares may be purchased at NAV by participants who are 
repaying loans made from such plans to the participant. 
 
Waiver of Initial Sales Charge-Class C Shares
 
  Benefit Plans. Class C shares may be purchased at NAV, without payment of 
an initial sales charge, by Benefit Plans (as defined above). In the case of 
Benefit Plans whose accounts are held directly with the Transfer Agent or 
Prudential Securities and for which the Transfer Agent or Prudential 
Securities does individual account recordkeeping (Direct Account Benefit 
Plans) and Benefit Plans sponsored by Prudential, Prudential Securities or 
its subsidiaries (Prudential Securities or Subsidiary Prototype Benefit 
Plans), Class C shares may be purchased at NAV by participants who are 
repaying the loans made from such plans to the participant. 
 
  Prudential Retirement Plans. The initial sales charge will be waived with 
respect to purchases of Class C shares by qualified and non-qualified 
retirement and deferred compensation plans participating in the PruArray Plan 
and other plans for which Prudential provides administrative or recordkeeping 
services. 
 
  Investments of Redemption Proceeds from Other Investment Companies. 
Investors may purchase Class C shares at NAV, without the initial sales 
charge, with the proceeds from the redemption of shares of any unaffiliated 
registered investment company which were not held through an account with any 
Prudential affiliate.                                        2 <PAGE>
 
Such purchases must be made within 60 days of the redemption. Investors 
eligible for this waiver include: (i) investors purchasing shares through an 
account at Prudential Securities Incorporated; (ii) investors purchasing 
shares through an ADVANTAGE Account or an Investor Account with Pruco 
Securities Corporation; and (iii) investors purchasing shares through other 
Dealers. This waiver is not available to investors who purchase shares 
directly from the Transfer Agent. You must notify the Transfer Agent directly 
or through your Dealer if you are entitled to this waiver and provide the 
Transfer Agent with such supporting documents as it may deem appropriate. 
 
Waiver of Class C Contingent Deferred Sales Charges
 
  Prudential Retirement Plans. The CDSC will be waived on redemptions from 
qualified and non-qualified retirement and deferred compensation plans that 
participate in the PruArray Program and other plans for which Prudential 
provides administrative or recordkeeping services. The CDSC will also be 
waived on redemptions from Benefit Plans sponsored by Prudential and its 
affiliates to the extent that the redemption proceeds are invested in The 
Guaranteed Investment Account, a group annuity insurance product issued by 
Prudential, the Guaranteed Insulated Separate Account, a separate account 
offered by Prudential, and units of The Stable Value Fund, an unaffiliated 
bank collective fund. 
 
  Other Benefit Plans. The CDSC will be waived on redemptions from Benefit 
Plans holding shares through a Dealer not affiliated with Prudential and for 
whom the Dealer provides administrative or recordkeeping services. 
 
Minimum Initial Investment for Class C Shares
 
  The minimum initial investment for Class C shares has been lowered to 
$2,500. The minimum initial investment for purchases made through the 
Automatic Investment Plan is $50. 
 
Expense Table - Example
 
  The following replaces the information on Class C shares under "Fund 
Expenses - Example."

Shareholder Guide
 
  The following replaces information under "Shareholder Guide - Alternative 
Purchase Plan". 
 
  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 Funds.                                 
       3 <PAGE>
 
  If you intend to hold your investment in a Fund for less than 3 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 3 years, but less than 
4 years, or for more than 5 years, but less than 6 years, you should consider 
purchasing Class A shares because the maximum 3% initial sales charge plus 
the cumulative annual distribution-related fee on Class A shares would be 
lower than: (i) the contingent deferred sales charge plus the cumulative 
annual distribution-related fee on Class B shares; and (ii) the 1% initial 
sales charge plus the cumulative annual distribution-related fee on Class C 
shares. 
 
  If you intend to hold your investment for more than 4 years, but less than 
5 years, you may consider purchasing Class A or Class B shares because: (i) 
the maximum 3% initial sales charge plus the cumulative annual 
distribution-related fee on Class A shares and (ii) the contingent deferred 
sales charge plus the cumulative annual distribution-related fee on Class B 
shares would be lower than the 1% initial sales charge plus the cumulative 
annual distribution-related fee on Class C shares. 
 
  If you intend to hold your investment for more than 6 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 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 
3 years for the 1% initial sales charge plus the higher cumulative annual 
distribution-related fee on the 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 NAV, the effect of the return on the investment 
over this period of time or redemptions when the CDSC is applicable. 
 
  The following information supplements "How the Fund is Managed-Distributor" 
in the Prospectus: 
 
  Effective July 1, 1998, Prudential Investment Management Services LLC (PIMS), 
Gateway Center Three, 100 Mulberry Street, Newark, New Jersey 07102-4077, was 
appointed the exclusive Distributor of Fund shares. Shares continue to be 
offered through Prudential Securities Incorporated, Pruco Securities 
Corporation and other brokers and dealers. PIMS is a wholly owned subsidiary of 
The Prudential Insurance Company of America and an affiliate of Prudential 
Securities Incorporated and Pruco Securities Corporation. All other 
arrangements with respect to the distribution of Fund shares described in the 
Prospectus remain unchanged.

  The following information supplements "General Information-Description of 
Common Stock" in the Prospectus: 
 
  The Fund is authorized to offer 1 billion shares of common stock, $.01 par 
value per share, divided into four classes of shares, designated Class A, Class 
B, Class C and Class Z shares, 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 (except for 
Class Z shares, which are not subject to any sales charges or 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 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, (iii) each class has a different exchange 
privilege, (iv) only Class B shares have a conversion feature and (v) Class Z 
shares are offered exclusively for sale to a limited group of investors. Since 
Class B and Class C shares generally bear higher distribution expenses than 
Class A shares, the liquidation proceeds to shareholders of those classes are 
likely to be lower than to Class A shareholders and to Class Z shareholders, 
whose shares are not subject to any distribution and/or service fee. In 
accordance with the Fund's Articles of Incorporation, the Board of Directors 
may authorize the creation of additional series and classes within such series, 
with such preferences, privileges, limitations and voting and dividend rights 
as the Directors may determine. Currently, the Fund is offering four classes, 
designated Class A, Class B, Class C and Class Z shares. 
 
  The following information supplements "Shareholder Guide-Shareholder 
Services" in the Prospectus: 
 
  The PruTector Program-Optional Group Term Life Insurance. Prudential makes 
available optional group term life insurance coverage to purchasers of shares 
of certain Prudential Mutual Funds which are held in an eligible brokerage 
account. This insurance protects the value of your mutual fund investment for

                                   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. As with an investment in any Mutual Fund, an
investment in this Fund can decrease in value and you can lose money.

WHO MANAGES THE FUND?

     Prudential Investments Fund Management LLC (PIFM 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, 1998, PIFM served as manager or administrator to 64 investment companies,
including 42 mutual funds, with aggregate assets of approximately $63 billion.
The Prudential Investment Corporation (PIC), 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 PIFM. See "How the Fund is
Managed--Manager" at page 18.

WHO DISTRIBUTES THE FUND'S SHARES?

     Prudential Securities Incorporated (Prudential Securities or the
Distributor), a major securities underwriter and securities and commodities
broker, acts as the Distributor of the Fund's shares. The Distributor 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 19.

<PAGE>

WHAT IS THE MINIMUM INVESTMENT?

     The minimum initial investment is $1,000 for Class A and Class B shares 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 26 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 22 and "Shareholder Guide--How to Buy Shares of the Fund" at page 26.

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 27.

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 30.

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 23.

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

The above example is based on data for the Fund's fiscal year ended
December 31, 1997.  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 various
costs and expenses that an investor in the Fund will bear, whether directly or
indirectly. For more complete descriptions of the various costs and expenses,
see "How the Fund Is Managed." "Other Expenses" include operating expenses of
the Fund, such as directors' and professional fees, registration 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."
 **  The expense information in the table has been restated to reflect current
     fees. Effective September 1, 1997, PIFM eliminated its management fee
     waiver (.05 of 1%). See "How the Fund is Managed--Manager--Fee Waivers."
  +  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, 1998.
     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 of 1986, as amended (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.

     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.


                                          7
<PAGE>

     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 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 NAV 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.


                                          8
<PAGE>

     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 NAV 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 ITS INVESTORS, 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 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" 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. As with an
investment in any mutual fund, an investment in the Fund can decrease in value
and you can lose money.

PUTS

     THE FUND MAY PURCHASE AND EXERCISE PUTS OR TENDER OPTIONS ON MUNICIPAL
BONDS 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 generally
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.


                                          9
<PAGE>

     ALTHOUGH MOST 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 NAV 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, or other
liquid assets with a futures commission merchant or in a segregated 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 marking-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).


                                          10
<PAGE>

This restriction does not apply to the purchase and sale of interest rate
futures contracts and options thereon for bona fide hedging purposes.

     SEGREGATION REQUIREMENTS. To the extent the Fund enters into futures
contracts, it is required by the Commission to maintain a segregated asset
account sufficient to cover the Fund's obligations with respect to such futures
contracts, which will consist of cash or other liquid 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 respect to such futures contracts. Offsetting the
contract by another identical contract eliminates the segregation requirement.
See "Investment Objective and Policies--Segregated Accounts" in the Statement of
Additional Information.

     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 for the term of the option cash 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 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 NAV 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, 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


                                          11
<PAGE>

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.

     To the extent the Fund is not covered as described above with respect to
written options, it will segregate and maintain for the term of the option cash
or liquid assets.


     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.


                                          12
<PAGE>

     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 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; and (5) 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


                                          13
<PAGE>

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 NAV. 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 in which it will maintain cash or other liquid assets 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


                                          14
<PAGE>

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.


     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 NAV 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


                                          15
<PAGE>

outstanding voting securities, as defined in the Investment Company Act of 1940,
as amended (the Investment Company Act). See "Investment Restrictions" in the
Statement of Additional Information.


                              HOW THE FUND IS MANAGED

     THE FUND HAS A BOARD OF DIRECTORS WHICH, IN ADDITION TO OVERSEEING THE
ACTIONS OF THE FUND'S MANAGER, SUBADVISER AND DISTRIBUTOR, AS SET FORTH BELOW,
DECIDES UPON MATTERS OF GENERAL POLICY. THE FUND'S MANAGER CONDUCTS AND
SUPERVISES THE DAILY BUSINESS OPERATIONS OF THE FUND. THE FUND'S SUBADVISER
FURNISHES DAILY INVESTMENT ADVISORY SERVICES.

     For the year ended December 31, 1997, the Fund's total expenses as a
percentage of average net assets for the Fund's Class A, Class B and Class C
shares were .70%, 1.10%, and 1.35%, respectively. See "Financial Highlights."


MANAGER

     PRUDENTIAL INVESTMENTS FUND MANAGEMENT LLC (PIFM OR THE MANAGER), GATEWAY
CENTER THREE, 100 MULBERRY STREET, NEWARK, NEW JERSEY 07102-4077 IS THE MANAGER

New York as a limited liability company. It is the successor to Prudential
Mutual Fund Management, Inc., which transferred its assets to PIFM in September
1996. For the fiscal year ended December 31, 1997, the Fund paid management fees
to PIFM of .48% of the Fund's average daily net assets. See "Fee Waivers" below
and "Manager" in the Statement of Additional Information.

     As of January 31, 1998, PIFM served as the manager to 42 open-end
investment companies, constituting all of the Prudential Mutual Funds, and as
manager or administrator to 22 closed-end investment companies, with aggregate
assets of approximately $63 billion.

     UNDER THE MANAGEMENT AGREEMENT WITH THE FUND, PIFM MANAGES THE INVESTMENT
OPERATIONS OF THE FUND AND ALSO ADMINISTERS THE FUND'S CORPORATE AFFAIRS. See
"Manager" in the Statement of Additional Information.

     UNDER A SUBADVISORY AGREEMENT BETWEEN PIFM AND THE PRUDENTIAL INVESTMENT
CORPORATION (PIC), DOING BUSINESS AS PRUDENTIAL INVESTMENTS (PI, THE SUBADVISER
OR THE INVESTMENT ADVISER), THE SUBADVISER FURNISHES INVESTMENT ADVISORY
SERVICES IN CONNECTION WITH THE MANAGEMENT OF THE FUND AND IS REIMBURSED BY PIFM
FOR ITS REASONABLE COSTS AND EXPENSES INCURRED IN PROVIDING SUCH SERVICES. PIFM
continues to have responsibility pursuant to the Management Agreement for all
investment advisory services and supervises the Subadviser's performance of such
services.

     The current portfolio manager of the Fund is Peter J. Allegrini, a Managing
Director of Prudential Investments. Mr. Allegrini is responsible for the
day-to-day management of the Fund's portfolio. Mr. Allegrini has managed the
Fund's portfolio since April 1996. Mr. Allegrini has been employed by PI as a

DISTRIBUTOR

     PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR THE
DISTRIBUTOR), ONE SEAPORT PLAZA, NEW YORK, NEW YORK 10292, 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), 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 the Distributor 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 the
Distributor and Prusec associated with the sale of Fund shares, including lease,
utility, communications and sales promotion expenses.

     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 THE DISTRIBUTOR FOR ITS
DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS A SHARES AT AN ANNUAL RATE
OF UP TO .30 OF 1% OF THE AVERAGE DAILY NAV 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. The Distributor 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, 1998.

     UNDER THE CLASS B AND CLASS C PLANS, THE FUND MAY PAY THE DISTRIBUTOR 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 the Distributor 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 the Distributor 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. The Distributor
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, 1998. The Distributor 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, 1997, 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


                                          17
<PAGE>

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 NAV 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.


FEE WAIVERS

     PIFM may from time to time waive its management fee or a portion thereof
and subsidize certain operating expenses of the Fund. The Fund is not required
to reimburse PIFM for such management fee waivers. Effective September 1, 1997,
PIFM discontinued its waiver of its management fee of .05% of 1% of the Funds
average daily net assets. See "Fund Expenses."

     The Distributor has agreed to limit its distribution fee for the Class A
and Class C shares as described above under "Distributor." Fee waivers will
increase the Fund's yield and total return. See "Performance Information" in the
Statement of Additional Information and "Fund Expenses" above.


PORTFOLIO TRANSACTIONS

     The Distributor 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 and Brokerage" in the
Statement of Additional Information.


CUSTODIAN AND TRANSFER AND DIVIDEND DISBURSING AGENT

     State Street Bank and Trust Company (State Street or the Custodian), One
Heritage Drive, North Quincy, Massachusetts 02171, serves as Custodian for the
Fund's portfolio securities and cash and, in that capacity, maintains certain
financial and accounting books and records pursuant to an agreement with the
Fund. Its mailing address is P.O. Box 1713, Boston, Massachusetts 02105.

     Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), Raritan
Plaza One, Edison, New Jersey 08837, serves as Transfer Agent and Dividend
Disbursing Agent and in those capacities maintains certain books and records for
the Fund. Its mailing address is P.O. Box 15005, New Brunswick, New Jersey
08906-5005. PMFS is a wholly-owned subsidiary of PIFM.


YEAR 2000

     The services provided to the Fund and the shareholders by the Manager, the
Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of their outside service
providers. Many computer software systems in use today cannot distinguish the
year 2000 from the year 1900 because of the way dates are encoded and
calculated. Such event could have a negative impact on handling securities
income, payments of interest and dividends, pricing and account services.
Although, at this time, there can be no assurance that there will be no adverse
impact on the Fund. The Manager, the Distributor, the Transfer Agent and the
Custodian have advised the Fund that they have been actively working on
necessary changes to their computer systems to prepare for the year 2000 and
expect that their systems, and those of their outside services, will be adapted
in time for that event.


                                          18
<PAGE>

                           HOW THE FUND VALUES ITS SHARES

     THE FUND'S 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.

     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 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


                                          19
<PAGE>

INCOME AND NET CAPITAL AND CURRENCY 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
capital gains (I.E., the excess of net capital gains from the sale of assets
held for more than 12 months over net short-term capital losses) distributed to
shareholders will be taxable as capital gains to the shareholders, whether or
not reinvested and regardless of the length of time a shareholder has owned his
or her shares. The maximum capital gains rate for individuals is 28% with
respect to assets held for more than 12 months, but not more than 18 months, and
20% with respect to assets held for more than 18 months. The maximum capital
gains rate for corporate shareholders currently is the same as the maximum tax
rate for ordinary income.

     It is not anticipated that corporate shareholders will be entitled to any
dividends received deduction with respect to distributions from the Fund.

     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.

     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 capital gain or
loss. In the case of an individual, any such capital gain will be treated as
short-term capital loss if the shares were held for not more than 12 months,
capital gain taxable at the maximum rate of 28% if such shares were held for
more than 12, but not more than 18 months, and capital gain, taxable at the
maximum rate of 20% if such shares were held for more than 18 months. In the
case of a corporation, any such capital gain will be treated as long-term
capital gain, taxable at the same rates as ordinary income, if such shares were
held for more than 12 months. Any such capital loss will be treated as long-term
capital loss if the shares have been held for more than one year and otherwise
as a short-term capital loss. Any such loss with respect to shares that are held
for six months or less however, will be disallowed to the extent of any exempt
interest dividends received with respect to such shares, or treated as long-term
capital loss to the extent of any capital gain distributions received by the
shareholder with respect to such shares.

     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)
or, generally, 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).

     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.


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 NAV 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 the Distributor, 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.

     Any dividends or distributions of net capital gains paid shortly after a
purchase by an investor will have the effect of reducing the NAV of the
investor's shares by the per share amount of the distributions. Although in
effect a return of invested principal, capital gain distribution and dividends,
to the extent such distributions are out of taxable net income, are subject to
federal income taxes. Accordingly, prior to purchasing shares of the Fund, an
investor should carefully consider the impact of dividends and distributions
which are expected to be or have been announced.

     IF YOU BUY SHARES ON OR IMMEDIATELY BEFORE THE RECORD DATE (THE DATE THAT
DETERMINED WHO RECEIVES THE DIVIDEND), YOU WILL RECEIVE A PORTION OF THE MONEY
YOU INVESTED AS A TAXABLE DIVIDEND. THEREFORE, YOU SHOULD CONSIDER THE TIMING OF
DIVIDENDS WHEN BUYING SHARES OF THE FUND.


                                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


                                          21
<PAGE>

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 Commission 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
Commission 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 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.

     This Prospectus, including the Statement of Additional Information which
has been incorporated by reference herein, does not contain all the information
set forth in the Registration Statement filed by the Fund with the Commission
under the Securities Act. Copies of the Registration Statement may be obtained

HOW TO BUY SHARES OF THE FUND

     YOU MAY PURCHASE SHARES OF THE FUND THROUGH THE DISTRIBUTOR, PRUSEC OR
DIRECTLY FROM THE FUND THROUGH ITS TRANSFER AGENT, PRUDENTIAL MUTUAL FUND
SERVICES LLC (PMFS OR THE TRANSFER AGENT), ATTENTION: INVESTMENT SERVICES, P.O.
BOX 15020, NEW BRUNSWICK, NEW JERSEY 08906-5020. The purchase price is the NAV
next determined following receipt of an order by the Transfer Agent or the
Distributor plus a sales charge which, at your option, 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 "Alternative Purchase Plan" below. See also, "How the Fund
Values its Shares." Payments may be made by cash, wire, check or through your
brokerage account.


                                          22

     AN INVESTMENT IN THE FUND MAY NOT BE APPROPRIATE FOR TAX-EXEMPT OR
TAX-DEFERRED INVESTORS. SUCH INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISERS.

     The minimum initial investment is $1,000 for Class A and Class B shares and
$5,000 for Class C shares. The minimum subsequent investment is $100 for all
classes. All minimum investment requirements are waived for certain employee
savings plans. For purchases through the Automatic Savings Accumulation Plan,
the minimum initial and subsequent investment is $50. See "Shareholder Services"
below.

     Application forms can be obtained from PMFS, the Distributor or Prusec. If
a stock certificate is desired, it must be requested in writing for each
transaction. Certificates are issued only for full shares. Shareholders who hold
their shares through the Distributor will not receive stock certificates.

     The Fund reserves the right to reject any purchase order (including an
exchange into the Fund) or to suspend or modify the continuous offering of its
shares. See "How to Sell Your Shares" below.

     Your dealer is responsible for forwarding payment promptly to the Fund. The
Distributor reserves the right to cancel any purchase order for which payment
has not been received by the third business day following the investment.

     Transactions in Fund shares may be subject to postage and handling charges
imposed by your dealer.

     PURCHASE BY WIRE. For an initial purchase of shares of the Fund by wire,
you must first telephone PMFS to receive an account number at (800) 225 -1852
(toll-free). The following information will be requested: your name, address,
tax identification number, class election, dividend distribution election,
amount being wired and wiring bank. Instructions should then be given by you to
your bank to transfer funds by wire to State Street Bank and Trust Company
(State Street), Boston, Massachusetts, Custody and Shareholder Services
Division, Attention: Prudential National Municipals Fund, Inc., specifying on
the wire the account number assigned by PMFS and your name and identifying the
class in which you are eligible to invest (Class A, Class B, or Class C shares).

     If you arrange for receipt by State Street of Federal Funds prior to the
calculation of NAV (4:15 P.M., New York time), on a business day, you may
purchase shares of the Fund as of that day. See "Net Asset Value in the
Statement of Additional Information.

     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.


                                          24
<PAGE>

     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 NAV, 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:

</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 from its own resources based on a percentage of the NAV 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.

     PRUARRAY SAVINGS PLAN. Class A shares are also offered at NAV to employees
of companies that enter into a written agreement with Prudential Retirement
Services to participate in the PruArray Savings Program. Under this Program, a
limited number of Prudential Mutual Funds are available for purchase at NAV by
Savings Accumulation Plans of the company's employees. The Program is available
only to employees who open a Savings Accumulation Plan account with the Transfer
Agent. The program is offered to companies that have at least 250 eligible
employees.


                                          25
<PAGE>

     SPECIAL RULES APPLICABLE TO RETIREMENT PLANS. After a PruArray Plan
qualifies to purchase Class A shares at NAV, all subsequent purchases will be
made at NAV.

     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 PIFM and their
subsidiaries and members of the families of such persons who maintain an
"employee related" account at Prudential Securities or the Transfer Agent, (c)
employees of subadvisers of the Prudential Mutual Funds provided that purchases
at NAV are permitted by such person's employer, (d) Prudential employees and
special agents of Prudential and its subsidiaries and all persons who have
retired directly from active service with Prudential or one of its subsidiaries,
(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, (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, from its
own resources, 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. 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, from its own resources, 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 THROUGH PRUDENTIAL SECURITIES. PLEASE CONTACT YOUR PRUDENTIAL
SECURITIES FINANCIAL ADVISER.

     IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A WRITTEN REQUEST FOR
REDEMPTION SIGNED BY YOU EXACTLY AS THE ACCOUNT IS REGISTERED IS REQUIRED. IF
YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(s) SHOWN ON THE FACE
OF THE CERTIFICATES, MUST BE RECEIVED BY THE TRANSFER AGENT 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


                                          26
<PAGE>

concerning redemptions should be sent to the Fund in care of the 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

     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 Commission,
by order, so permits; provided that applicable rules and regulations of the
Commission 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 CASHIER'S 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 Commission. 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 are redeemed in kind, you would incur transaction costs in
converting the assets into cash. The Fund, however, has elected to be governed
by Rule 18f-1 under the Investment Company Act, under which the Fund is
obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of
the NAV of the Fund during any 90-day period for any one shareholder.

     INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the 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 CDSC 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 NAV next
determined after the order is received, which must be within 90 days after the
date of the redemption. Any CDSC paid in connection with such redemption will be
credited (in shares) to your account. (If less than a full repurchase is made,
the credit will be on a PRO RATA basis.) You must notify the Fund's Transfer
Agent, either directly or through the Distributor, 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 may not affect federal tax treatment of any gain
realized upon redemption.


     CONTINGENT DEFERRED SALES CHARGES

     Redemptions of Class B shares will be subject to a 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


                                          27
<PAGE>

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

</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 NAV 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 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 the
Distributor 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


                                          28
<PAGE>

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 be redeemed without charge. The
Transfer Agent will calculate the total amount available for this waiver
annually on the anniversary date of your purchase or, for shares purchased prior
to March 1, 1997, on March 1 of the current year. The CDSC will be waived (or
reduced) on redemptions until this threshold 12% is reached.

     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 NAV without the imposition of any additional sales charge.

     Since the Fund tracks amounts paid rather than the number of shares bought
on each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will be
determined on each conversion date in accordance with the following formula: (i)
the ratio of (a) the amounts paid for Class B shares purchased at least seven
years prior to the conversion date to (b) the total amount paid for all Class B
shares purchased and then held in your account (ii) multiplied by the total
number of Class B shares purchased and then held in your account. Each time any
Eligible Shares in your account convert to Class A shares, all shares or amounts
representing Class B shares then in your account that were acquired through the
automatic reinvestment of dividends and other distributions will convert to
Class A shares.

     For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different net asset values per share, the number of Eligible Shares
calculated as described above will generally be either more or less than the
number of shares actually purchased approximately seven years before such
conversion date. For example, if 100 shares were initially purchased at $10 per
share (for a total of $1,000) and a second purchase of 100 shares was
subsequently made at $11 per share (for a total of $1,100), 95.24 shares would
convert approximately seven years from the initial purchase (i.e., $1,000
divided by $2,100 (47.62%) multiplied by 200 shares equals 95.24 shares). The
Manager reserves the right to modify the formula for determining the number of
Eligible Shares in the future as it deems appropriate on notice to shareholders.

     Since annual distribution-related fees are lower for Class A shares than
Class B shares, the per share NAV of the Class A shares may be higher than that
of the Class B shares at the time of conversion. Thus, although the aggregate
dollar value will be the same, you may receive fewer Class A shares than Class B
shares converted. 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 and Class C shares
will not


                                          29
<PAGE>

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, Inc. 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. 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 THE DISTRIBUTOR, 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 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 NAV above the total amount of payments for the purchase of
Class B or Class C shares and (3) amounts representing Class B or Class C shares
held beyond the applicable CDSC period. Class B and Class C shareholders must
notify the Transfer Agent either directly or through the Distributor or Prusec
that they are eligible for this special exchange privilege.


                                          30
<PAGE>

     The exchange privilege is not a right and may be suspended, modified or
terminated on 60 days' notice to shareholders.

     FREQUENT TRADING. The Fund and other Prudential Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market timing
investment strategies and excessive trading can have on efficient portfolio
management, each Prudential Mutual Fund and the Fund reserves the right to
refuse purchase orders and exchanges by any person, group or commonly controlled
accounts, if, in the Manager's sole judgment, such person, group or accounts
were following a market timing strategy or were otherwise engaging in excessive
trading (Market Timers).

     To implement this authority to protect the Fund and its shareholders from
excessive trading, the Fund will reject all exchanges and purchases from a
Market Timer unless the Market Timer has entered into a written agreement with
the Fund or its affiliates pursuant to which the Market Timer has agreed to
abide by certain procedures, which include a daily dollar limit on trading. The
Fund may notify the Market Timer of rejection of an exchange or purchase order
subsequent to the day on which the order was placed.


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, 100 Mulberry Street, 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, 100 Mulberry Street, Newark, New Jersey 07102-4077, or by
telephone at (800) 225-1852 (toll-free) or, from outside the U.S.A., at (908)

Prudential Municipal Series Fund
(Maryland Series)
 
- ----------------------------------------------
 
   
PROSPECTUS DATED NOVEMBER 2, 1998
    
 
- ----------------------------------------------------------------
 
Prudential Municipal Series Fund (the Fund) (Maryland Series) (the Series) is
one of thirteen series of an open-end, management investment company, or mutual
fund. This Series is diversified and is designed to provide the maximum amount
of income that is exempt from Maryland State and federal income taxes consistent
with the preservation of capital and, in conjunction therewith, the Series may
invest in debt securities with the potential for capital gain. The net assets of
the Series are invested primarily in obligations within the four highest ratings
of Moody's Investors Service, Standard & Poor's Ratings Group or another
nationally recognized statistical rating organization or in unrated obligations
which, in the opinion of the Fund's investment adviser, are of comparable
quality. The Series may, however, also invest a portion of its assets in lower-
quality municipal obligations or in non-rated securities which, in the opinion
of the Fund's investment adviser, are of comparable quality. Subject to the
limitations described herein, the Series may utilize derivatives, including
buying and selling futures contracts and options thereon for the purpose of
hedging its portfolio securities. There can be no assurance that the Series'
investment objective will be achieved. See "How the Fund Invests--Investment
Objective and Policies." The Fund's address is Gateway Center Three, 100
Mulberry Street, Newark, New Jersey 07102-4077, and its telephone number is
(800) 225-1852.
 
   
The Trustees of the Fund have recently approved a proposal to exchange the
assets and liabilities of the Series of the Fund for shares of Prudential
National Municipals Fund, Inc. (National Municipals Fund). Class A, Class B and
Class C shares of the Series would be exchanged at relative net asset value for
Class A shares of National Municipals Fund. The transfer has been approved by
the Trustees of the Fund and by the Board of Directors of National Municipals
Fund and is subject to approval by the shareholders of the Series. It is
anticipated that a proxy statement/prospectus relating to the transaction will
have been mailed to the Series' shareholders in late October 1998. EFFECTIVE
IMMEDIATELY, THE FUND WILL NO LONGER ACCEPT ORDERS TO PURCHASE OR EXCHANGE FOR
SHARES OF THE SERIES, EXCEPT FOR PURCHASES BY CERTAIN RETIREMENT AND EMPLOYEE
PLANS (EXCLUDING IRA ACCOUNTS). Existing shareholders may continue to acquire
shares through dividend reinvestment. The current redemption privilege and the
current exchange privilege of obtaining shares of other Prudential Mutual Funds
will remain in effect until the transaction is consummated. If the transaction
is not consummated, the Fund will resume accepting orders to purchase or
exchange for shares of the Series. See "Shareholder Guide--How to Buy Shares of
the Fund."

                                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 THE SERIES' INVESTMENT OBJECTIVE?
 
    The Series' investment objective is to maximize current income that is
  exempt from Maryland State and federal income taxes consistent with the
  preservation of capital. It seeks to achieve this objective by investing
  primarily in Maryland State, municipal and local government obligations and
  obligations of other qualifying issuers, such as issuers located in Puerto
  Rico, the Virgin Islands and Guam, which pay income exempt, in the opinion
  of counsel, from Maryland State and federal income taxes (Maryland
  Obligations). There can be no assurance that the Series' investment
  objective will be achieved. See "How the Fund Invests--Investment Objective
  and Policies" at page 8.
 
  WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?
 
   
    In seeking to achieve its investment objective, the Series will invest at
  least 80% of the value of its total assets in Maryland Obligations. This
  degree of investment concentration makes the Series particularly susceptible
  to factors adversely affecting issuers of Maryland Obligations. See "How the
  Fund Invests--Investment Objective and Policies--Special Considerations" at
  page 13. The Series may invest up to 30% of its total assets in high yield
  securities, commonly known as junk bonds, which may be considered
  speculative and are subject to the risk of an issuer's inability to meet
  principal and interest payments on the obligations as well as price
  volatility. See "How the Fund Invests--Investment Objective and
  Policies--Risk Factors Relating to Investing in High Yield Municipal
  Obligations" at page 11. To hedge against changes in interest rates, the
  Series may also purchase put options and engage in transactions involving
  derivatives, including financial futures contracts and options thereon. See
  "How the Fund Invests--Investment Objective and Policies--Futures Contracts
  and Options Thereon" at page 12. As with an investment in any mutual fund,
  an investment in this Series can decrease in value and you can lose money.
    
 
  WHO MANAGES THE FUND?
 
   
    Prudential Investments Fund Management LLC (PIFM 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 Series' average daily net assets. As of September 30, 1998,
  PIFM served as manager or administrator to 66 investment companies,
  including 44 mutual funds, with aggregate assets of approximately $67
  billion. The Prudential Investment Corporation (PIC, the Subadviser or the
  investment adviser) furnishes investment advisory services in connection
  with the management of the Fund under a Subadvisory Agreement with PIFM. See
  "How the Fund is Managed--Manager" at page 15.
    
 
   
  WHO DISTRIBUTES THE SERIES' SHARES?
    
 
   
    Prudential Investment Management Services LLC (the Distributor) acts as
  the Distributor of the Series' Class A, Class B and Class C shares and is
  paid a distribution and service fee with respect to Class A shares at the
  rate of .25 of 1% of the average daily net assets of the Class A shares and
  is paid a distribution and service fee with respect to Class B shares at the
  annual rate of .50 of 1% of the average daily net assets of the Class B
  shares and is paid an annual distribution and service fee with respect to
  Class C shares 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 15.
    
 
                                       2
<PAGE>
  WHAT IS THE MINIMUM INVESTMENT?
 
   
    The minimum initial investment is $1,000 for Class A and Class B shares
  and $2,500 for Class C shares. The minimum subsequent investment is $100 for
  Class A, Class B and Class C shares. There is no minimum investment
  requirement for certain employee savings plans. For purchases made through
  the Automatic Investment Plan, the minimum initial and subsequent investment
  is $50. See "Shareholder Guide--How to Buy Shares of the Fund" at page 22
  and "Shareholder Guide--Shareholder Services" at page 32.
    
 
  HOW DO I PURCHASE SHARES?
 
   
    You may purchase shares of the Series through the Distributor or brokers
  or dealers that have entered into agreements to act as participating or
  introducing brokers for the Distributor (Dealers) or directly from the Fund
  through its transfer agent, Prudential Mutual Fund Services LLC (PMFS or the
  Transfer Agent). In each case, sales are made at the net asset value per
  share (NAV) next determined after receipt of your purchase order by the
  Transfer Agent, a Dealer or the Distributor plus a sales charge, which may
  be imposed at the time of purchase, on a deferred basis, or both. Class A
  shares are sold with a front-end sales charge. Class B shares are subject to
  a contingent-deferred sales charge (CDSC). Class C shares are sold with a
  low front-end sales charge, but are also subject to a CDSC. Dealers may
  charge their customers a separate fee for handling purchase transactions.
  See "How the Fund Values its Shares" at page 18 and "Shareholder Guide--How
  to Buy Shares of the Fund" at page 22.
    
 
  WHAT ARE MY PURCHASE ALTERNATIVES?
 
    The Series 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 with an initial sales charge of 1% of the
                         offering price and are also subject to a CDSC of 1%
                         on redemptions for a period of 18 months after
                         purchase. Class C shares are subject to higher
                         ongoing distribution-related expenses than Class A
                         shares but, unlike Class B shares, do not convert
                         to another class.
    
 
   
    See "Shareholder Guide--Alternative Purchase Plan" at page 24.
    
 
  HOW DO I SELL MY SHARES?
 
   
    You may redeem your shares at any time at the NAV next determined after
  your Dealer, the Distributor or the Transfer Agent receives your sell order.
  The proceeds of redemptions of Class B and Class C shares may be subject to
  a CDSC. Dealers may charge their customers a separate fee for handling sale
  transactions. See "Shareholder Guide--How to Sell Your Shares" at page 27.
    
 
  HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
 
    The Series expects to declare daily and pay monthly dividends of net
  investment income, if any, and make distributions of any net capital gains
  at least annually. Dividends and distributions will be automatically
  reinvested in additional shares of the Series at NAV without a sales charge
  unless you request that they be paid to you in cash. See "Taxes, Dividends
  and Distributions" at page 19.

   The purpose of this table is to assist investors in understanding the
   various costs and expenses that an investor in the Series will bear,
   whether directly or indirectly. For more complete descriptions of the
   various costs and expenses, see "How the Fund is Managed." The above
   examples are based on restated data for the Series' fiscal year ended
   August 31, 1998. "Other Expenses" includes Trustees' and professional
   fees, registration fees, reports to shareholders and 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."
    
   
+      Dealers independently may charge additional fees for shareholder
       transactions or advisory services. 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 Series may not exceed 6.25% of total gross sales, subject to
       certain exclusions. This 6.25% limitation is on each class of the Series
       rather than on a per shareholder basis. Therefore, long-term shareholders
       of the Series 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, Class B and Class C Distribution and Service Plans
       provide that the Fund may pay a distribution fee of up to .30 of 1%, .50
       of 1% and 1% per annum of the average daily net assets of the Class A,
       Class B and Class C shares, respectively, the Distributor may voluntarily
       limit its distribution fees. Presently the Distributor limits its
       distribution fees with respect to the Class A, Class B and Class C shares
       of the Series to no more than .10 of 1%, .10 of 1% and .25 of 1% of the
       average daily net asset value of the Class A, Class B and Class C shares,
       respectively. This voluntary limitation may be modified or terminated at
       any time without notice. The Distributor anticipates modifying its
       present limitation for Class A and Class C shares so that, in the future,
       the Fund will pay distribution fees of .25% and .75%, respectively, and
       eliminating its present limitation for Class B shares so that, in the
       future, the Fund will pay distribution fees of .50%. Total Fund Operating
       Expenses of the Class A and Class C shares without any limitations would
       be 1.39% and 2.08%, respectively. See "How the Fund is
       Managed--Distributor."

                              HOW THE FUND INVESTS
 
INVESTMENT OBJECTIVE AND POLICIES
 
  PRUDENTIAL MUNICIPAL SERIES FUND (THE FUND) IS AN OPEN-END, MANAGEMENT
INVESTMENT COMPANY, OR MUTUAL FUND, CONSISTING OF THIRTEEN SEPARATE SERIES. EACH
OF THESE SERIES IS MANAGED INDEPENDENTLY. THE MARYLAND SERIES (THE SERIES) IS
DIVERSIFIED AND ITS INVESTMENT OBJECTIVE IS TO MAXIMIZE CURRENT INCOME THAT IS
EXEMPT FROM MARYLAND STATE AND FEDERAL INCOME TAXES CONSISTENT WITH THE
PRESERVATION OF CAPITAL AND, IN CONJUNCTION THEREWITH, THE SERIES MAY INVEST IN
DEBT SECURITIES WITH THE POTENTIAL FOR CAPITAL GAIN. See "Investment Objectives
and Policies" in the Statement of Additional Information.
 
  THE SERIES' INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE, MAY
NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE SERIES'
OUTSTANDING VOTING SECURITIES AS DEFINED IN THE INVESTMENT COMPANY ACT OF 1940,
AS AMENDED (THE INVESTMENT COMPANY ACT). THE SERIES' POLICIES THAT ARE NOT
FUNDAMENTAL MAY BE MODIFIED BY THE TRUSTEES.
 
  THE SERIES WILL INVEST PRIMARILY IN MARYLAND STATE, MUNICIPAL AND LOCAL
GOVERNMENT OBLIGATIONS AND OBLIGATIONS OF OTHER QUALIFYING ISSUERS, SUCH AS
ISSUERS LOCATED IN PUERTO RICO, THE VIRGIN ISLANDS AND GUAM, WHICH PAY INCOME
EXEMPT, IN THE OPINION OF COUNSEL, FROM MARYLAND STATE AND FEDERAL INCOME TAXES
(MARYLAND OBLIGATIONS). THERE CAN BE NO ASSURANCE THAT THE SERIES WILL BE ABLE
TO ACHIEVE ITS INVESTMENT OBJECTIVE.
 
  As with an investment in any mutual fund, an investment in this Series can
decrease and you can lose money.
 
   
  Interest on certain municipal obligations may be a preference item for
purposes of the federal alternative minimum tax. The Series may invest without
limit in municipal obligations that are private activity bonds (as defined in
the Internal Revenue Code) the interest on which would be a preference item for
purposes of the federal alternative minimum tax (AMT bonds). See "Taxes,
Dividends and Distributions." Under Maryland law, dividends paid by the Series
are exempt from Maryland personal income tax for resident individuals to the
extent they are derived from interest payments on and, in some cases, gain from
the sale of Maryland Obligations, provided, however, that up to 50% of dividends
attributable to interest received by the Series on AMT bonds could be subject to
Maryland individual income tax. Maryland Obligations could include general
obligation bonds of the State, counties, cities, towns, etc., revenue bonds of
utility systems, highways, bridges, port and airport facilities, colleges,
hospitals, etc., and industrial development and pollution control bonds. The
Series will invest in long-term obligations, and the dollar-weighted average
maturity of the Series' portfolio will generally range between 10-20 years. The
Series also may invest in certain short-term, tax-exempt notes such as Tax
Anticipation Notes, Revenue Anticipation Notes, Bond Anticipation Notes,
Construction Loan Notes and variable and floating rate demand notes.
    
 
   
  Generally, municipal obligations with longer maturities produce higher yields
and are subject to greater price fluctuations as a result of changes in interest
rates (market risk) than municipal obligations with shorter maturities. The
prices of municipal obligations vary inversely with interest rates. Interest
rates are currently much lower than in recent years. As a general matter, bond
prices and the Series' NAV will vary inversely with interest rate fluctuations.
If rates were to rise sharply, the prices of bonds in the Series' portfolio
might be adversely affected.
    
 
  THE SERIES MAY INVEST ITS ASSETS IN FLOATING RATE AND VARIABLE RATE
SECURITIES, INCLUDING PARTICIPATION INTERESTS THEREIN AND INVERSE FLOATERS.There
is no limit on the amount of such securities that the Series may purchase.
Floating rate securities normally have a rate of interest which is set as a
specific percentage of a designated base rate, such as the rate on Treasury
bonds or bills or the prime rate at a major commercial bank. The interest rate
on floating rate securities changes periodically when there is a change in the
designated base interest rate. Variable rate securities provide for a specified
periodic adjustment in the interest rate based on prevailing market rates and
generally would allow the Series to demand payment of the obligation on short
notice at par plus accrued interest, which amount may be more or less than the
amount the Series paid for
 
                                       8
<PAGE>
them. 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.
 
  THE SERIES 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) or the
acquisition of equipment. 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 Trustees. Municipal lease obligations will not be considered illiquid for
purposes of the Series' 15% limitation on illiquid securities provided the
investment adviser determines that there is a readily available market for such
securities. See "Other Investments and Policies--Illiquid Securities" below.
 
   
  THE SERIES WILL INVEST AT LEAST 70% OF ITS TOTAL ASSETS IN MARYLAND
OBLIGATIONS WHICH, AT THE TIME OF PURCHASE, ARE RATED WITHIN THE FOUR HIGHEST
QUALITY GRADES AS DETERMINED BY MOODY'S INVESTORS SERVICE (MOODY'S) (CURRENTLY
Aaa, Aa, A, Baa FOR BONDS, MIG 1, MIG 2, MIG 3, MIG 4 FOR NOTES AND PRIME-1 FOR
COMMERCIAL PAPER), STANDARD & POOR'S RATINGS GROUP (S&P) (CURRENTLY AAA, AA, A,
BBB FOR BONDS, SP-1, SP-2 FOR NOTES AND A-1 FOR COMMERCIAL PAPER) OR ANOTHER
NATIONALLY RECOGNIZED STATISTICAL RATING ORGANIZATION (NRSRO) OR, IF UNRATED,
WILL POSSESS CREDITWORTHINESS, IN THE OPINION OF THE INVESTMENT ADVISER,
COMPARABLE TO SUCH INVESTMENT GRADE RATED SECURITIES.
    
 
   
  THE SERIES MAY ALSO INVEST UP TO 30% OF ITS TOTAL ASSETS IN MARYLAND
OBLIGATIONS RATED BELOW Baa BY MOODY'S OR BELOW BBB BY S&P, OR A COMPARABLE
RATING OF ANOTHER NRSRO OR, IF NON-RATED, OF COMPARABLE QUALITY, IN THE OPINION
OF THE FUND'S INVESTMENT ADVISER, BASED ON ITS CREDIT ANALYSIS. Securities rated
Baa by Moody's and BBB by S&P are described as being investment grade but are
also characterized as having speculative characteristics. Securities rated below
Baa by Moody's and below BBB by S&P are considered speculative. See "Description
of Security Ratings" in the Appendix. Such lower-rated high yield securities are
commonly referred to as junk bonds. Such securities generally offer a higher
current yield than those in the higher rating categories but may also involve
greater price volatility and risk of loss of principal and income. The
investment adviser will attempt to manage risk and enhance yield through credit
analysis and careful security selection. See "Risk Factors Relating to Investing
in High Yield Municipal Obligations" below. Subsequent to its purchase by the
Series, a municipal obligation may be assigned a lower rating or cease to be
rated. Such an event would not require the elimination of the issue from the
portfolio, but the investment adviser will consider such an event in determining
whether the Series should continue to hold the security in its portfolio. Many
issuers of lower-quality bonds choose not to have their obligations rated and
the Series may invest in such unrated securities. Investors should carefully
consider the relative risks associated with investments in securities which
carry lower ratings and in comparable non-rated securities.
    
 
   
  During the year ended August 31, 1998, the monthly dollar weighted average
ratings of the debt obligations held by the Series, expressed as a percentage of
the Series' total assets, were as follows:

<PAGE>
  From time to time, the Series may own the majority of a municipal issue. Such
majority-owned holdings may present market and credit risks.
 
  The Series may purchase Maryland Obligations which, in the opinion of the
investment adviser, offer the opportunity for capital appreciation. This may
occur, for example, when the investment adviser believes that the issuer of a
particular Maryland Obligation might receive an upgraded credit standing,
thereby increasing the market value of the bonds it has issued or when the
investment adviser believes that interest rates might decline.
 
  UNDER NORMAL MARKET CONDITIONS, THE SERIES WILL ATTEMPT TO INVEST
SUBSTANTIALLY ALL OF THE VALUE OF ITS ASSETS IN MARYLAND OBLIGATIONS. As a
matter of fundamental policy, during normal market conditions the Series' assets
will be invested so that at least 80% of the income will be exempt from Maryland
State and federal income taxes or the Series will have at least 80% of its total
assets invested in Maryland Obligations. During abnormal market conditions or to
provide liquidity, the Series may hold cash or cash equivalents or investment
grade taxable obligations, including obligations that are exempt from federal,
but not state, taxation and the Series may invest in tax-free cash equivalents,
such as floating rate demand notes, tax-exempt commercial paper and general
obligation and revenue notes or in taxable cash equivalents, such as
certificates of deposit, bankers acceptances and time deposits or other
short-term taxable investments such as repurchase agreements. When, in the
opinion of the investment adviser, abnormal market conditions require a
temporary defensive position, the Series may invest more than 20% of the value
of its assets in debt securities other than Maryland Obligations or may invest
its assets so that more than 20% of the income is subject to Maryland State or
federal income taxes. The Series will treat an investment in a municipal bond
refunded with escrowed U.S. Government securities as U.S. Government securities
for purposes of the Investment Company Act's diversification requirements
provided certain conditions are met. See "Investment Objectives and Policies--In
General" in the Statement of Additional Information.
 
   
  THE SERIES MAY ACQUIRE PUT OPTIONS (PUTS) GIVING THE SERIES THE RIGHT TO SELL
SECURITIES HELD IN THE SERIES' PORTFOLIO AT A SPECIFIED EXERCISE PRICE ON A
SPECIFIED DATE. Such puts may be acquired for the purpose of protecting the
Series from a possible decline in the market value of the security to which the
put applies in the event of interest rate fluctuations or, in the case of
liquidity puts, for the purpose of shortening the effective maturity of the
underlying security. The aggregate value of premiums paid to acquire puts held
in the Series' portfolio (other than liquidity puts) may not exceed 10% of the
NAV of the Series. The acquisition of a put may involve an additional cost to
the Series by payment of a premium for the put, by payment of a higher purchase
price for securities to which the put is attached or through a lower effective
interest rate.
    
 
  In addition, there is a credit risk associated with the purchase of puts in
that the issuer of the put may be unable to meet its obligation to purchase the
underlying security. Accordingly, the Series will acquire puts only under the
following circumstances: (1) the put is written by the issuer of the underlying
security and such security is rated within the four highest quality grades as
determined by an NRSRO; or (2) the put is written by a person other than the
issuer of the underlying security and such person has securities outstanding
which are rated within such four highest quality grades; or (3) the put is
backed by a letter of credit or similar financial guarantee issued by a person
having securities outstanding which are rated within the two highest quality
grades of an NRSRO.
 
   
  THE SERIES 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 the securities take place at a later date. During the period between
purchase and settlement, no interest accrues to the economic benefit of the
purchaser. In the case of purchases by the Series, the price that the Series 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 Series 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 Series makes the commitment to purchase a
municipal obligation on a when-issued or delayed delivery basis, it will record
the transaction and reflect the value of the obligation each day in determining
its NAV. This value may fluctuate from day to day in the same manner as
    
 
                                       10
<PAGE>
   
values of municipal obligations otherwise held by the Series. If the seller
defaults in the sale, the Series could fail to realize the appreciation, if any,
that had occurred. The Series will establish a segregated account in which it
will maintain cash or other liquid assets, equal or greater in value to its
commitments for when-issued or delayed delivery securities.
    
 
  THE SERIES MAY ALSO PURCHASE MUNICIPAL FORWARD CONTRACTS. A municipal forward
contract is a municipal security which is purchased on a when-issued basis with
delivery taking place up to five years from the date of purchase. No interest
will accrue on the security prior to the delivery date. The investment adviser
will monitor the liquidity, value, credit quality and delivery of the security
under the supervision of the Trustees.
 
  THE SERIES MAY PURCHASE SECONDARY MARKET INSURANCE ON MARYLAND OBLIGATIONS
WHICH IT HOLDS OR ACQUIRES. Secondary market insurance would be reflected in the
market value of the municipal obligation purchased and may enable the Series 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 Maryland Obligations held by the Series 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 NAV of the
shares of the Series.
    
 
   
  RISK FACTORS RELATING TO INVESTING IN HIGH YIELD MUNICIPAL
OBLIGATIONS. FIXED-INCOME SECURITIES ARE SUBJECT TO THE RISK OF AN ISSUER'S
INABILITY TO MEET PRINCIPAL AND INTEREST PAYMENTS ON THE OBLIGATIONS (CREDIT
RISK) AND MAY ALSO BE SUBJECT TO PRICE VOLATILITY DUE TO SUCH FACTORS AS
INTEREST RATE SENSITIVITY, MARKET PERCEPTION OF THE CREDITWORTHINESS OF THE
ISSUER AND GENERAL MARKET LIQUIDITY (MARKET RISK). Lower-rated or unrated (I.E.,
high yield) securities, commonly known as junk bonds, are more likely to react
to developments affecting market and credit risk than are more highly rated
securities, which react primarily to movements in the general level of interest
rates. The investment adviser will perform its own investment analysis and will
not rely principally on the ratings assigned by the rating services, although
such ratings will be considered by the investment adviser. The investment
adviser will consider, among other things, credit risk and market risk, as well
as the financial history and condition, the prospects and the management of an
issuer in selecting securities for the Series' portfolio. The achievement of the
Series' investment objective may be more dependent on the investment adviser's
credit analysis than is the case when investing in only higher quality bonds.
Investors should carefully consider the relative risks of investing in high
yield municipal obligations and understand that such securities are not
generally meant for short-term investing and that yields on junk bonds will
fluctuate over time.
    
 
   
  The amount of high yield securities outstanding has proliferated recently in
conjunction with the decline in creditworthiness of many obligors on municipal
debt, particularly health care providers and certain governmental bodies. An
economic downturn could severely affect the ability of highly leveraged issuers
to service their debt obligations or to repay their obligations upon maturity.
Furthermore, changes in economic conditions and other circumstances are more
likely to lead to a weakened capacity to make principal and interest payments
than in the case of higher grade bonds. In addition, the secondary market for
high yield securities, which is concentrated in relatively few market makers,
may not be as liquid as the secondary market for more highly rated securities
and, from time to time, it may be more difficult to value high yield securities
than more highly rated securities, and the judgment of the Board of Trustees and
investment adviser may play a greater role in valuation because there is less
reliable objective data available. Under adverse market or economic conditions,
the secondary market for high yield securities could contract further,
independent of any specific adverse changes in the condition of a particular
issuer. As a result, the investment adviser could find it more difficult to sell
these securities or may be able to sell the securities only at prices lower than
if such securities were widely traded. Prices realized upon the sale of such
lower rated or unrated securities, under these circumstances, may be less than
the prices used in calculating the Series' NAV. If the investment adviser
becomes involved in activities such as reorganizations of obligors of troubled
investments held by the Series, this may prevent the Series from disposing of
the securities, due to its possession of material, non-public information
concerning the obligor.
    
 
                                       11
<PAGE>
   
  LOWER-RATED OR UNRATED DEBT OBLIGATIONS ALSO PRESENT RISKS BASED ON PAYMENT
EXPECTATIONS. If an issuer calls the obligation for redemption, the Series may
have to replace the security with a lower-yielding security, resulting in a
decreased return for investors. If the Series experiences unexpected net
redemptions, it may be forced to sell its higher rated securities, resulting in
a decline in the overall credit quality of the portfolio and increasing the
exposure of the Series to the risks of high yield securities.
    
 
  FUTURES CONTRACTS AND OPTIONS THEREON
 
   
  THE SERIES IS AUTHORIZED TO PURCHASE AND SELL CERTAIN DERIVATIVES, INCLUDING
FINANCIAL FUTURES CONTRACTS (FUTURES CONTRACTS) AND OPTIONS THEREON FOR THE
PURPOSE OF HEDGING ITS PORTFOLIO SECURITIES AGAINST FLUCTUATIONS IN VALUE CAUSED
BY CHANGES IN PREVAILING MARKET INTEREST RATES AND HEDGING AGAINST INCREASES IN
THE COST OF SECURITIES THE SERIES INTENDS TO PURCHASE. THE SUCCESSFUL USE OF
FUTURES CONTRACTS AND OPTIONS THEREON BY THE SERIES INVOLVES ADDITIONAL
TRANSACTION COSTS, IS SUBJECT TO VARIOUS RISKS AND DEPENDS UPON THE INVESTMENT
ADVISER'S ABILITY TO PREDICT THE DIRECTION OF THE MARKET (INCLUDING INTEREST
RATES). THE SERIES, AND THUS INVESTORS, MAY LOSE MONEY THROUGH ANY UNSUCCESSFUL
USE OF THESE STRATEGIES.
    
 
  A FUTURES CONTRACT OBLIGATES THE SELLER OF THE CONTRACT TO DELIVER TO THE
PURCHASER OF THE CONTRACT CASH EQUAL TO A SPECIFIC DOLLAR AMOUNT TIMES THE
DIFFERENCE BETWEEN THE VALUE OF A SPECIFIC FIXED-INCOME SECURITY OR INDEX AT THE
CLOSE OF THE LAST TRADING DAY OF THE CONTRACT AND THE PRICE AT WHICH THE
AGREEMENT IS MADE. No physical delivery of the underlying securities is made.
The Series will engage in transactions in only those futures contracts and
options thereon that are traded on a commodities exchange or a board of trade.
 
   
  THE SERIES INTENDS TO ENGAGE IN FUTURES CONTRACTS AND OPTIONS THEREON AS A
HEDGE AGAINST CHANGES, RESULTING FROM MARKET CONDITIONS, IN THE VALUE OF
SECURITIES WHICH ARE HELD IN THE SERIES' PORTFOLIO OR WHICH THE SERIES INTENDS
TO PURCHASE, IN ACCORDANCE WITH THE RULES AND REGULATIONS OF THE COMMODITY
FUTURES TRADING COMMISSION (CFTC). The Series also intends to engage in such
transactions when they are economically appropriate for the reduction of risks
inherent in the ongoing management of the Series.
    
 
   
  THE SERIES MAY NOT PURCHASE OR SELL FUTURES CONTRACTS OR OPTIONS THEREON IF,
IMMEDIATELY THEREAFTER, (I) THE SUM OF INITIAL AND NET CUMULATIVE VARIATION
MARGIN ON OUTSTANDING FUTURES CONTRACTS, TOGETHER WITH PREMIUMS PAID FOR OPTIONS
THEREON, WOULD EXCEED 20% OF THE TOTAL ASSETS OF THE SERIES, OR (II) IN THE CASE
OF RISK MANAGEMENT TRANSACTIONS, THE SUM OF THE AMOUNT OF INITIAL MARGIN
DEPOSITS ON THE SERIES' FUTURES POSITIONS AND PREMIUMS PAID FOR OPTIONS THEREON
WOULD EXCEED 5% OF THE LIQUIDATION VALUE OF THE SERIES' TOTAL ASSETS. There are
no limitations on the percentage of the portfolio which may be hedged and no
limitations on the use of the Series' assets to cover futures contracts and
options thereon, except that the aggregate value of the obligations underlying
put options will not exceed 50% of the Series' assets.
    
 
  Currently, futures contracts are available on several types of fixed-income
securities, including U.S. Treasury bonds and notes, three-month U.S. Treasury
bills and Eurodollars. Futures contracts are also available on a municipal bond
index, based on THE BOND BUYER Municipal Bond Index, an index of 40 actively
traded municipal bonds. The Series may also engage in transactions in other
futures contracts that become available, from time to time, in other
fixed-income securities or municipal bond indices and in other options on such
contracts if the investment adviser believes such contracts and options would be
appropriate for hedging the Series' portfolio.
 
  THERE CAN BE NO ASSURANCE THAT VIABLE MARKETS WILL CONTINUE OR THAT A LIQUID
SECONDARY MARKET WILL EXIST TO TERMINATE ANY PARTICULAR FUTURES CONTRACT AT ANY
SPECIFIC TIME. If it is not possible to close a futures position entered into by
the Series, the Series will continue to be required to make daily cash payments
of variation margin in the event of adverse price movements. In such a
situation, if the Series had insufficient cash, it might have to sell portfolio
securities to meet daily variation margin requirements at a time when it might
be disadvantageous to do so. The inability to close futures positions also could
have an adverse impact on the ability of the Series to hedge effectively. There
is also a risk of loss by the Series of margin deposits in the event of
bankruptcy of a broker with whom the Series has an open position in a futures
contract.
 
                                       12
<PAGE>
  THE SUCCESSFUL USE OF FUTURES CONTRACTS AND OPTIONS THEREON BY THE SERIES IS
SUBJECT TO VARIOUS ADDITIONAL RISKS. Any use of futures transactions involves
the risk of imperfect correlation in movements in the price of futures contracts
and movements in interest rates and, in turn, the prices of the securities that
are the subject of the hedge. If the price of the futures contract moves more or
less than the price of the security that is the subject of the hedge, the Series
will experience a gain or loss that will not be completely offset by movements
in the price of the security. The risk of imperfect correlation is greater where
the securities underlying futures contracts are taxable securities (rather than
municipal securities), are issued by companies in different market sectors or
have different maturities, ratings or geographic mixes than the security being
hedged. In addition, the correlation may be affected by additions to or
deletions from the index which serves as the basis for a futures contract.
Finally, if the price of the security that is subject to the hedge were to move
in a favorable direction, the advantage to the Series would be partially offset
by the loss incurred on the futures contract.
 
  SPECIAL CONSIDERATIONS
 
   
  BECAUSE THE SERIES WILL INVEST AT LEAST 80% OF THE VALUE OF ITS TOTAL ASSETS
IN MARYLAND OBLIGATIONS AND BECAUSE IT SEEKS TO MAXIMIZE INCOME DERIVED FROM
MARYLAND OBLIGATIONS, IT IS MORE SUSCEPTIBLE TO FACTORS ADVERSELY AFFECTING
ISSUERS OF MARYLAND OBLIGATIONS THAN IS A COMPARABLE MUNICIPAL BOND MUTUAL FUND
THAT IS NOT CONCENTRATED IN SUCH OBLIGATIONS TO THIS DEGREE. During the three
fiscal years from 1991 through 1993, the State's finances were severely affected
by the national recession. Nevertheless, the State closed fiscal year 1993 with
a $10.5 million operating surplus on a budgetary basis and closed fiscal year
1994 with a $60 million operating surplus on a budgetary basis. On a GAAP basis,
the State's General Fund moved from a deficit of $121.7 million as of June 30,
1993 to a positive balance of $113.9 million on June 30, 1994. Financial
operations continued to improve in fiscal year 1995, with revenues exceeding
estimates by $217 million and expenditures at $184 million above budget.
Estimates for 1996 General Fund revenues were revised downward by $148 million,
compared to projections made in the enacted budget; nevertheless, the State
closed fiscal year 1996 with a General Fund balance on a budgetary basis of
$13.1 million and $461.2 million in the Revenue Stabilization Account of the
State Reserve Fund. The State had a General Fund balance for fiscal 1997 on a
budgetary basis of $144.5 million and $490.4 million in the Revenue
Stabilization Account of the State Reserve Fund. The enacted 1997 budget held
overall appropriations to slightly over 1996 levels, reflecting slowed revenue
growth and the absence of an appropriation to the now fully funded Revenue
Stabilization Account of the State Reserve Fund.
    
 
   
  In April 1997 the General Assembly approved a $15.4 billion 1998 fiscal year
budget. This budget (i) includes funds sufficient to meet all specific statutory
funding requirements; (ii) incorporates the first year of a five-year phase-in
of a 10% reduction in personal income taxes (estimated to reduce revenues by
$38.5 million in fiscal year 1998 and $450 million when fully phased in) and
certain reductions in sales taxes on certain manufacturing equipment (estimated
to reduce revenues by $38.6 million when the reductions are fully phased in
fiscal year 2001); and (iii) includes the first year's $30 million funding under
an agreement to provide additional funds totaling $230 million over a five-year
period to schools in the City of Baltimore and related grants to other
subdivisions totaling $32 million. As of July, 1998, the State projected ending
fiscal year 1998 with a General Fund balance on a budgetary basis of $317.2
million and $617 million in the Revenue Stabilization Account of the State
Reserve Fund.
    
 
  Other issuers of Maryland Obligations are subject to various risks and
uncertainties, and the credit quality of the securities issued by them may vary
considerably from the credit quality of obligations issued by the State. If
either the State or any of its local governmental entities is unable to meet its
financial obligations, the income derived by the Series, the ability to preserve
or realize appreciation of the Series' capital and the Series' liquidity could
be adversely affected. See "Investment Objectives and Policies--Special
Considerations Regarding Investments in Tax-Exempt Securities" in the Statement
of Additional Information.

OTHER INVESTMENTS AND POLICIES
 
  REPURCHASE AGREEMENTS
 
   
  The Series may on occasion enter into repurchase agreements whereby the seller
of a security agrees to repurchase that security from the Series at a mutually
agreed-upon time and price. The period of maturity is usually quite short,
possibly overnight or a few days, although it may extend over a number of
months. The resale price is in excess of the purchase price, reflecting an
agreed-upon rate of return effective for the period of time the Series' money is
invested in the repurchase agreement. The Series' repurchase agreements will at
all times be fully collateralized in an amount at least equal to the resale
price. The instruments held as collateral are valued daily and if the value of
the instruments declines, the Series will require additional collateral. If the
seller defaults and the value of the collateral securing the repurchase
agreement declines, the Series may incur a loss. The Series participates in a
joint repurchase account with other investment companies managed by PIFM
pursuant to an order of the Commission.
    
 
  BORROWING
 
  The Series 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) for temporary, extraordinary
or emergency purposes or for the clearance of transactions. The Series may
pledge up to 33 1/3% of the value of its total assets to secure these
borrowings. The Series will not purchase portfolio securities if its borrowings
exceed 5% of its total assets.
 
  PORTFOLIO TURNOVER
 
   
  The Series does not expect to trade in securities for short-term gain. It is
anticipated that the annual portfolio turnover rate will not exceed 150%. The
portfolio turnover rate is calculated by dividing the lesser of sales or
purchases of portfolio securities by the average monthly value of the portfolio
securities, excluding securities having a maturity at the date of purchase of
one year or less. High portfolio turnover of a Series may involve
correspondingly greater brokerage commissions and other transaction costs, which
will be borne directly by that Series. In addition, high portfolio turnover may
result in increased short-term capital gains, which, when distributed to
shareholders, are treated as ordinary income. See "Taxes, Dividends and
Distributions."
    
 
  ILLIQUID SECURITIES
 
   
  The Series may hold up to 15% of its net assets in illiquid securities
including repurchase agreements which have a maturity of longer than seven days,
securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable. Securities,
including restricted securities eligible for resale pursuant to Rule 144A under
the Securities Act of 1933, as amended (the Securities Act), privately placed
commercial paper and 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 restricted securities
under the supervision of the Trustees. The Series' investment in Rule 144A
securities could have the effect of increasing illiquidity to the extent that
qualified institutional buyers become, for a limited time, uninterested in
purchasing Rule 144A securities. See "Investment Objectives and
Policies--Illiquid Securities" and "Investment Restrictions" in the Statement of
Additional Information. Repurchase agreements subject to demand are deemed to
have a maturity equal to the notice period.
    
 
INVESTMENT RESTRICTIONS
 
  The Series 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
Series' outstanding voting securities, as defined in the Investment Company Act.
See "Investment Restrictions" in the Statement of Additional Information.

DISTRIBUTOR
 
   
  PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC (THE DISTRIBUTOR), GATEWAY
CENTER THREE, 100 MULBERRY STREET, NEWARK, NEW JERSEY 07102-4077, IS A LIMITED
LIABILITY COMPANY ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE
    
 
                                       15
<PAGE>
   
AND SERVES AS THE DISTRIBUTOR OF THE SHARES OF THE SERIES. IT IS A WHOLLY-OWNED
SUBSIDIARY OF PRUDENTIAL. Prudential Securities Incorporated (Prudential
Securities), One Seaport Plaza, New York, New York 10292, previously served as
distributor of the Series' shares. 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, COLLECTIVELY, THE PLANS) ADOPTED BY THE FUND UNDER
RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT AND A DISTRIBUTION AGREEMENT (THE
DISTRIBUTION AGREEMENT), THE DISTRIBUTOR INCURS THE EXPENSES OF DISTRIBUTING THE
CLASS A, CLASS B AND CLASS C SHARES OF THE SERIES. These expenses include
commissions and account servicing fees paid to, or on account of, Dealers or
financial institutions which have entered into agreements with the Distributor,
advertising expenses, the cost of printing and mailing prospectuses to potential
investors and indirect and overhead costs of the Distributor associated with the
sale of Series shares, including lease, utility, communications and sales
promotion expenses. Certain Dealers are paid higher fees than others with
respect to Class A shares pursuant to separate agreements with the Distributor.
    
 
  Under the Plans, the Series 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 Series will
not be obligated to pay any additional expenses. If the Distributor's expenses
are less than such distribution and service fees, it will retain its full fees
and realize a profit.
 
   
  The distribution and/or service fees may also be used by the Distributor to
compensate on a continuing basis Dealers in consideration for the distribution,
marketing, administrative and other services and activities provided by Dealers
with respect to the promotion of the sale of the Series' shares and the
maintenance of related shareholder accounts.
    
 
   
  UNDER THE CLASS A PLAN, THE SERIES MAY PAY THE DISTRIBUTOR FOR ITS
DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS A SHARES AT AN ANNUAL RATE
OF UP TO .30 OF 1% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS A SHARES OF THE
SERIES. 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. The Distributor has
voluntarily limited 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. This
voluntary limitation may be modified or terminated at any time without notice.
    
 
   
  UNDER THE CLASS B AND CLASS C PLANS, THE SERIES MAY PAY THE DISTRIBUTOR 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 the Distributor 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 B and Class C shares, respectively, 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. The Distributor has voluntarily limited its
distribution-related fees payable under the Class B and Class C Plans to .10 of
1% and .25 of 1% of the average daily net assets of the Class B and Class C
shares, respectively. These voluntary limitations may be modified or terminated
at any time without notice. The Distributor also receives CDSC's from certain
redeeming shareholders. See "Shareholder Guide--How to Sell Your
Shares--Contingent Deferred Sales Charges."
    
 
   
  For the fiscal year ended August 31, 1998, the Series paid distribution
expenses of .10 of 1%, .50 of 1% and .75 of 1% of the average daily net assets
of the Class A, Class B and Class C shares, respectively. The Series records all
payments made under the Plans as expenses in the calculation of net investment
income. See "Distributor" in the Statement of Additional Information.
    
 
                                       16
<PAGE>
   
  Distribution expenses attributable to the sale of Class A, Class B and Class C
shares of the Series will be allocated to each such class based upon the ratio
of sales of each such class to the sales of Class A, Class B or Class C shares
of the Series other than expenses allocable to a particular class. The
distribution fee and sales charge of one class will not be used to subsidize the
sale of another class.
    
 
   
  Each Plan provides that it shall continue in effect from year to year provided
that a majority of the Trustees of the Fund, including a majority of the
Trustees 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
Trustees), vote annually to continue the Plan. Each Plan may be terminated with
respect to the Series at any time by vote of a majority of the Rule 12b-1
Trustees or of a majority of the outstanding shares of the applicable class of
the Series. The Series will not be obligated to pay distribution and service
fees incurred under any Plan if it is terminated or not continued.
    
 
   
  In addition to distribution and service fees paid by the Series 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 and other persons which
distribute shares of the Series. Such payments may be calculated by reference to
the NAV of shares sold by such persons or otherwise.
    
 
   
  The Distributor is subject to the rules of the National Association of
Securities Dealers, Inc. (the NASD) governing maximum sales charges. See
"Distributor" in the Statement of Additional Information.
    
 
   
PORTFOLIO TRANSACTIONS
    
 
   
  Affiliates of the Distributor may act as brokers or futures commission
merchants for the Fund, provided that the commissions, fees or other
remuneration they receive are fair and reasonable. See "Portfolio Transactions
and Brokerage" in the Statement of Additional Information.
    
 
CUSTODIAN AND TRANSFER AND DIVIDEND DISBURSING AGENT
 
  State Street Bank and Trust Company, One Heritage Drive, North Quincy,
Massachusetts 02171, serves as Custodian for the portfolio securities of the
Series and cash and, in that capacity, maintains certain financial and
accounting books and records pursuant to an agreement with the Fund. Its mailing
address is P.O. Box 1713, Boston, Massachusetts 02105.
 
   
  Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), Raritan
Plaza One, Edison, New Jersey 08837, serves as Transfer Agent and Dividend
Disbursing Agent and, in those capacities, maintains certain books and records
for the Fund. PMFS is a wholly-owned subsidiary of PIFM. Its mailing address is
P.O. Box 15005, New Brunswick, New Jersey 08906-5005.
    
 
   
YEAR 2000
    
 
   
  The services provided to the Fund and the shareholders by the Manager, the
Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of outside service providers.
Many computer software systems in use today cannot distinguish the year 2000
from the year 1900 because of the way dates are encoded and calculated. Such
event could have a negative impact on handling securities trades, payments of
interest and dividends, pricing and account services. Although, at this time,
there can be no assurance that there will be no adverse impact on the Fund, the
Manager, the Distributor, the Transfer Agent and the Custodian have advised the
Fund that they have been actively working on necessary changes to their computer
systems to prepare for the year 2000 and expect that their systems, and those of
outside service providers, will be adapted in time for the event.
    
 
   
  Additionally, issuers of securities generally as well as those purchased by
the Fund may confront year 2000 compliance issues which, if material and not
resolved, could have an adverse impact on securities markets and/or a specific
issuer's performance and result in a decline in the value of securities held by
the Fund.
    
 
                                       17
<PAGE>
                         HOW THE FUND VALUES ITS SHARES
 
   
  THE SERIES' NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING ITS
LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE REMAINDER BY THE
NUMBER OF OUTSTANDING SHARES. NAV IS CALCULATED SEPARATELY FOR EACH CLASS. THE
TRUSTEES HAVE FIXED THE SPECIFIC TIME OF DAY FOR THE COMPUTATION OF THE NAV OF
THE SERIES 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 Trustees. Securities may also be valued based on values
provided by a pricing service. See "Net Asset Value" in the Statement of
Additional Information.
 
  The Series 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 Series or days on which changes in
the value of the Series' portfolio securities do not materially affect the NAV.
 
   
  Although the legal rights of each class of shares are substantially identical,
the different expenses borne by each class will result in different NAV's 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 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 THE YIELD, TAX EQUIVALENT YIELD AND
AVERAGE ANNUAL TOTAL RETURN AND AGGREGATE TOTAL RETURN OF THE SERIES 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
Series over a one-month or 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 Series. The total
return shows how much an investment in the Series would have increased
(decreased) over a specified period of time (I.E., one, five or ten years or
since inception of the Series) assuming that all distributions and dividends by
the Series 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 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 shares of
the Series. 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 Series' 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 SERIES HAS QUALIFIED AND INTENDS TO REMAIN QUALIFIED AS A REGULATED
INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, THE SERIES WILL
NOT BE SUBJECT TO FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME AND NET
CAPITAL GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS. TO THE EXTENT
NOT DISTRIBUTED BY THE SERIES, NET TAXABLE INVESTMENT INCOME AND CAPITAL GAINS
AND LOSSES ARE TAXABLE TO THE SERIES. See "Taxes, Dividends and Distributions"
in the Statement of Additional Information.
    
 
   
  To the extent the Series invests in taxable obligations, it will earn taxable
investment income. Also, to the extent the Series sells securities or engages in
hedging transactions in futures contracts and options thereon, it may earn both
capital gain or loss. Capital gain or loss may also arise upon the sale of
municipal securities, as well as taxable obligations. Under the Internal Revenue
Code, special rules apply to the treatment of certain options and futures
contracts (Section 1256 contracts). At the end of each year, such investments
held by the Series will be required to be marked to market for federal income
tax purposes; that is, treated as having been sold at market value. Sixty
percent of any gain or loss recognized on these deemed sales and on actual
dispositions will be treated as long-term capital gain or loss, and the
remainder will be treated as short-term capital gain or loss. See "Taxes,
Dividends and Distributions" in the Statement of Additional Information.
    
 
   
  Gain or loss realized by the Series 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 taxable ordinary
income to the extent of any market discount. Market discount generally is the
difference, if any, between the price paid by the Series 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 issue price of the security). The market
discount rule does not apply to any security that was acquired by the Series at
its original issue.
    
 
TAXATION OF SHAREHOLDERS
 
  In general, the character of tax-exempt interest distributed by the Series
will flow through as tax-exempt interest to its shareholders provided that 50%
or more of the value of its assets at the end of each quarter of its taxable
year is invested in state, municipal and other obligations, the interest on
which is excluded from gross income for federal income tax purposes. During
normal market conditions, at least 80% of the Series' total assets will be
invested in such obligations. See "How the Fund Invests--Investment Objective
and Policies."
 
   
  Any dividends out of net investment income, together with distributions of net
short-term gains (I.E., the excess of net short-term capital gains over net
long-term capital losses) distributed to shareholders, will be taxable as
ordinary income to the shareholder whether or not reinvested. Any net capital
gains (I.E., the excess of net capital gains from the sale of assets held for
more than 12 months over net short-term capital losses) distributed to
shareholders will be taxable as capital gains to the shareholders, whether or
not reinvested and regardless of the length of time a shareholder has owned his
or her shares. Recent legislation created various categories of capital gains
applicable to individuals. For capital gains recognized upon the sale of assets
by the Series after December 31, 1997. The maximum long-term capital gains tax
rate for individuals is 20%. The maximum capital gains tax rate for corporate
shareholders currently is the same as the maximum tax rate for ordinary income.
    
 
   
  Any gain or loss realized upon a sale or redemption of Series shares by a
shareholder who is not a dealer in securities will be treated as capital gain or
loss. Any such capital gain or loss will be treated as long-term capital gain or
loss if the shares were held for more than 12 months. In the case of an
individual, any such long-term capital gain will be taxable at the maximum rate
of 20%. The maximum capital gain tax rate for a corporation is the same as that
for ordinary income. Any loss with respect to shares that
    
 
                                       19
<PAGE>
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. In addition, any short-term capital loss will be disallowed to the
extent of any tax-exempt dividends received by the shareholder on shares that
are held for six months or less.
 
  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 Class
B or Class C shares for Class A shares constitutes a taxable event for federal
income tax purposes. However, such opinions are not binding on the Internal
Revenue Service.
 
   
  CERTAIN INVESTORS MAY INCUR FEDERAL ALTERNATIVE MINIMUM TAX LIABILITY AS A
RESULT OF THEIR INVESTMENT IN THE FUND. Tax-exempt interest from certain
municipal obligations (I.E., certain private activity bonds issued after August
7, 1986) will be treated as an item of tax preference for purposes of the
alternative minimum tax. The Fund anticipates that, under regulations to be
promulgated, items of tax preference incurred by the Series will be attributed
to the Series' shareholders, although some portion of such items could be
allocated to the Series itself. Depending upon each shareholder's individual
circumstances, the attribution of items of tax preference incurred by the Series
could result in liability for the shareholder for the alternative minimum tax.
Similarly, the Series could be liable for the alternative minimum tax for items
of tax preference attributed to it. The Series is permitted to invest in
municipal obligations of the type that will produce items of tax preference.
    
 
   
  Distributions relating to interest on all municipal obligations will be
included in a corporate shareholder's current earnings for purposes of the
adjustment for current earnings for alternative minimum tax purposes. Corporate
shareholders should consult with their tax advisers with respect to this
potential adjustment.
    
 
  Under Maryland law, dividends paid by the Series are exempt from Maryland
personal income tax for individuals who reside in Maryland to the extent such
dividends are exempt from federal income tax and are derived from interest
payments on Maryland Obligations, provided, however, that up to 50% of dividends
attributable to interest received by the Series on certain private activity
bonds which are not issued by the State of Maryland or its political
subdivisions could be subject to Maryland individual income tax. In addition,
distributions attributable (i) to gain realized by the Series on the disposition
of those Maryland Obligations issued by the State of Maryland or its political
subdivisions and (ii) to interest received by the Series on U.S. Government
obligations are exempt from Maryland personal income tax.
 
  Distributions other than those described as exempt in the preceding paragraph
will be subject to Maryland personal income tax.
 
   
  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 Series is required to withhold and remit
to the U.S. Treasury 31% of redemption proceeds on the accounts of certain
shareholders who fail to furnish their tax identification numbers on IRS Form
W-9 (or IRS Form W-8 in the case of certain foreign shareholders) with the
required certifications regarding the shareholder's status under the federal
income tax law. Such withholding also is required on taxable dividends and
capital gain distributions made by the Series unless it is reasonably expected
that at least 95% of the distributions of the Series are comprised of tax-exempt
dividends.
 
  Dividends of net taxable investment income and distributions of net short-term
capital gains paid to a shareholder (including a shareholder acting as a nominee
or fiduciary) who is a nonresident alien individual, a foreign corporation or a
foreign partnership (foreign shareholder) are subject to a 30% (or lower treaty
rate) withholding tax upon the gross amount of the dividends unless the
dividends are effectively connected with a U.S. trade or business conducted by
the foreign shareholder. Capital gain dividends paid to a foreign shareholder
are generally not subject to withholding tax. A foreign shareholder will,
however, be required to pay U.S. income tax on any dividends and capital gain
distributions which are effectively connected with a U.S. trade or business of
the foreign shareholder.

DIVIDENDS AND DISTRIBUTIONS
 
  THE SERIES EXPECTS TO DECLARE DAILY AND PAY MONTHLY DIVIDENDS OF NET
INVESTMENT INCOME, IF ANY, AND MAKE DISTRIBUTIONS AT LEAST ANNUALLY OF ANY
CAPITAL GAINS IN EXCESS OF CAPITAL LOSSES. Dividends paid by the Series 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 charges,
generally resulting in lower dividends for Class B and Class C 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 SHARES OF THE SERIES
BASED ON THE NAV OF EACH CLASS OF THE SERIES ON THE PAYMENT DATE AND RECORD
DATE, RESPECTIVELY, OR SUCH OTHER DATE AS THE TRUSTEES 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 of both the
dollar amount and the taxable status of that year's dividends and distributions
on a per share basis.
    
 
   
  IF YOU BUY SHARES ON OR IMMEDIATELY BEFORE THE RECORD DATE (THE DATE THAT
DETERMINES WHO RECEIVES THE DIVIDEND), YOU WILL RECEIVE A PORTION OF THE MONEY
YOU INVESTED AS A TAXABLE DIVIDEND. THEREFORE, YOU SHOULD CONSIDER THE TIMING OF
DIVIDENDS WHEN BUYING SHARES OF THE FUND.
    
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
 
  THE FUND WAS ESTABLISHED AS A MASSACHUSETTS BUSINESS TRUST ON MAY 18, 1984, BY
A DECLARATION OF TRUST. The Fund's activities are supervised by its Trustees.
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares in separate series, currently designated as the
Connecticut Money Market Series, Florida Series, Maryland Series, Massachusetts
Series, Massachusetts Money Market Series, Michigan Series, New Jersey Series,
New Jersey Money Market Series, New York Series, New York Money Market Series,
North Carolina Series, Ohio Series and Pennsylvania Series. The Series is
authorized to issue an unlimited number of shares, divided into three classes,
designated Class A, Class B and Class C. Each class of shares represents an
interest in the same assets of the Series and are identical in all respects
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 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, (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." In accordance with the Fund's Declaration of Trust, the
Trustees may authorize the creation of additional series and classes within such
series, with such preferences, privileges, limitations and voting and dividend
rights as the Trustees may determine.
 
  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
the Series is equal as to earnings, assets and voting privileges, except as
noted above, and each class 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 beneficial interest of each series is entitled to
its portion of all of the Fund's assets after all debt and expenses of the Fund
have
 
                                       21
<PAGE>
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 Trustees.
 
  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 TRUSTEES IS REQUIRED TO BE
ACTED UPON 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 TRUSTEES OR TO TRANSACT ANY OTHER BUSINESS.
 
  The Declaration of Trust and the By-Laws of the Fund are designed to make the
Fund similar in certain respects to a Massachusetts business corporation. The
principal distinction between a Massachusetts business corporation and a
Massachusetts business trust relates to shareholder liability. Under
Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
fund, which is not the case with a corporation. The Declaration of Trust of the
Fund provides that shareholders shall not be subject to any personal liability
for the acts or obligations of the Fund and that every written obligation,
contract, instrument or undertaking made by the Fund shall contain a provision
to the effect that the shareholders are not individually bound thereunder.
 
ADDITIONAL INFORMATION
 
   
  This Prospectus, including the Statement of Additional Information which has
been incorporated by reference herein, does not contain all the information set
forth in the Registration Statement filed by the Fund with the Commission under
the Securities Act. Copies of the Registration Statement may be obtained at a
reasonable charge from the Commission or may be examined, without charge, at the
office of the Commission in Washington, D.C.
    
 
                               SHAREHOLDER GUIDE
 
HOW TO BUY SHARES OF THE FUND
 
   
  The Trustees of the Fund have recently approved a proposal to exchange the
assets and liabilities of the Series of the Fund for shares of Prudential
National Municipals Fund, Inc. (National Municipals Fund). Class A, Class B and
Class C shares of the Series would be exchanged at relative net asset value for
Class A shares of National Municipals Fund, the investment objective of which is
to seek a high level of current income exempt from federal income taxes. The
transfer has been approved by the Trustees of the Fund and by the Board of
Directors of National Municipals Fund and is subject to approval by the
shareholders of the Series. It is anticipated that a proxy statement/prospectus
relating to the transaction will be mailed to the Series' shareholders in late
October 1998.
    
 
   
  Under the terms of the proposal, shareholders of the Series would become
shareholders of National Municipals Fund. No sales charge would be imposed on
the proposed transfer. The Fund anticipates obtaining an opinion of its counsel
that the transaction would be a tax-free reorganization under the Internal
Revenue Code and therefore no gain or loss for Federal income tax purposes would
be recognized by shareholders of the Series.
    
 
   
  EFFECTIVE IMMEDIATELY, THE FUND WILL NO LONGER ACCEPT ORDERS TO PURCHASE OR
EXCHANGE FOR SHARES OF THE SERIES, EXCEPT FOR PURCHASES BY CERTAIN RETIREMENT
AND EMPLOYEE PLANS (EXCLUDING IRA ACCOUNTS). Existing shareholders may continue
to acquire shares through dividend reinvestment. The current redemption
privilege and the current exchange privilege of obtaining shares of other
Prudential Mutual Funds will remain in effect until the transaction is
consummated. If the transaction is not consummated, the Fund will resume
accepting orders to purchase or exchange for shares of the Series. See "How to
Sell Your Shares" and "How to Exchange Your Shares" below.
    
 
                                       22
<PAGE>
   
  IF THE FUND RESUMES ACCEPTING ORDERS TO PURCHASE SHARES OF THE SERIES, YOU MAY
PURCHASE SHARES OF THE SERIES THROUGH THE DISTRIBUTOR, THROUGH DEALERS INCLUDING
PRUDENTIAL SECURITIES OR PRUSEC, OR DIRECTLY FROM THE FUND THROUGH ITS TRANSFER
AGENT, PRUDENTIAL MUTUAL FUND SERVICES LLC (PMFS OR THE TRANSFER AGENT),
ATTENTION: INVESTMENT SERVICES, P.O. BOX 15020, NEW BRUNSWICK, NEW JERSEY
08906-5020. The purchase price is the NAV next determined following receipt of
an order in proper form (in accordance with procedures established by the
Transfer Agent in connection with investors' accounts) by the Distributor, your
Dealer or the Transfer Agent plus a sales charge which, at your option, may be
imposed either at the time of purchase, on a deferred basis, or both. Class A
shares are sold with a front-end sales charge. Class B shares are subject to a
CDSC. Class C shares are sold with a low front-end sales charge, but are also
subject to a CDSC. Payments may be made by wire, check or through your brokerage
account. See also "Alternative Purchase Plan" below and "How the Fund Values its
Shares."
    
 
  An investment in the Series may not be appropriate for tax-exempt or
tax-deferred investors. Such investors should consult their own tax advisers.
 
   
  The minimum initial investment is $1,000 for Class A and Class B shares and
$2,500 for Class C shares. The minimum subsequent investment is $100 for all
classes. All minimum investment requirements are waived for certain employee
savings plans. For purchases made through the Automatic Investment Plan, the
minimum initial and subsequent investment is $50. See "Shareholder Services"
below.
    
 
  The Fund reserves the right to reject any purchase order (including an
exchange into the Series) or to suspend or modify the continuous offering of its
shares. See "How to Sell Your Shares" below.
 
   
  Application forms can be obtained from the Transfer Agent, your Dealer or the
Distributor. If a share certificate is desired, it must be requested in writing
for each transaction. Certificates are issued only for full shares. Shareholders
who hold their shares through Prudential Securities will not receive share
certificates.
    
 
   
  Your Dealer is responsible for forwarding payment promptly to the Fund. The
Distributor reserves the right to cancel any purchase order for which payment
has not been received by the third business day following the placement of the
order.
    
 
   
  Dealers may charge their customers a separate fee for processing purchases and
redemptions. In addition, transactions in shares of the Series may be subject to
postage and handling charges imposed by your Dealer. Any such charge is retained
by the Dealer and is not remitted to the Fund.
    
 
  PURCHASE BY WIRE. For an initial purchase of shares of the Series by wire, you
must first telephone PMFS at (800) 225-1852 (toll-free) to receive an account
number. The following information will be requested: your name, address, tax
identification number, class election, dividend distribution election, amount
being wired and wiring bank. Instructions should then be given by you to your
bank to transfer funds by wire to State Street Bank and Trust Company (State
Street), Boston, Massachusetts, Custody and Shareholder Services Division,
Attention: Prudential Municipal Series Fund (Maryland Series), specifying on the
wire the account number assigned by PMFS and your name and identifying the class
in which you are eligible to invest (Class A, Class B or Class C shares).
 
   
  If you arrange for receipt by State Street of federal funds prior to the
calculation of NAV (4:15 P.M., New York time), on a business day, you may
purchase shares of the Series as of that day. See "Net Asset Value" in the
Statement of Additional Information.
    
 
   
  In making a subsequent purchase order by wire, you should wire State Street
directly and should be sure that the wire specifies Prudential Municipal Series
Fund, the name of the Series, 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.

             of the amount invested or the                                               purchase

             the amount invested or the
             redemption proceeds on redemptions
             made within 18 months of purchase
</TABLE>
    
 
   
  The three classes of shares represent an interest in the same portfolio of
investments of the Series 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 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, (iii) each
class has a different exchange privilege, 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 the Class A shares.
    
 
   
  Dealers, financial advisers and other sales agents who sell shares of the
Series 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 Series:
    
 
   
  If you intend to hold your investment in a Fund for less than 3 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.
    
 
                                       24
<PAGE>
   
  If you intend to hold your investment for more than 3 years, but less than 4
years, or for more than 5 years, but less than 6 years, you should consider
purchasing Class A shares, because the maximum 3% initial sales charge plus the
cumulative annual distribution-related fee on Class A shares would be lower
than: (i) the CDSC plus the cumulative annual distribution-related fee on Class
B shares; and (ii) the 1% initial sales charge plus the cumulative annual
distribution-related fee on Class C shares.
    
 
   
  If you intend to hold your investment for more than 4 years, but less than 5
years, you may consider purchasing Class A or Class B shares because: (i) the
maximum 3% initial sales charge plus the cumulative annual distribution-related
fee on Class A shares and (ii) the CDSC plus the cumulative annual
distribution-related fee on Class B shares would be lower than the 1% initial
sales charge plus the cumulative annual distribution-related fee on Class C
shares.
    
 
   
  If you intend to hold your investment for more than 6 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 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 3
years for the 1% initial sales charge plus the higher cumulative annual
distribution-related fee on the 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 NAV, the effect of the return on the investment over this period
of time or redemptions when 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.
Dealers may be deemed to be underwriters, as that term is defined under federal
securities laws. The Distributor reserves the right, without prior notice to any
Dealer, to suspend or eliminate Dealer concessions or commissions.
    
 
   
  In connection with the sale of Class A shares at NAV (without payment of an
initial sales charge), the Manager, the Distributor or one of their affiliates
may pay Dealers, financial advisers and other persons which distribute shares a
finders' fee from their own resources based on a percentage of the NAV of shares
sold by such persons.
    
 
  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 the Distributor
or the Transfer Agent, by the following persons: (a) officers of Prudential
Mutual Funds (including the Fund), (b) employees of the Distributor, Prudential
Securities, PIFM and their subsidiaries and members of the families of such
persons who maintain an employee related account at Prudential Securities or the
Transfer Agent, (c) employees of subadvisers of the Prudential Mutual Funds
provided that the purchases at NAV are permitted by such person's employer, (d)
Prudential, employees and special agents of Prudential and its subsidiaries and
all persons who have retired directly from active service with Prudential or one
of its subsidiaries, (e) registered representatives and employees of Dealers who
have entered into a selected dealer agreement with the Distributor, 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.
    
 
   
  For an investor to obtain any reduction or waiver of the initial sales
charges, at the time of the sale either the Transfer Agent must be notified
directly by the investor or the Distributor must be notified by the Dealer
facilitating the transaction that the sale qualifies for the reduced or waived
sales charge. The reduction or waiver will be granted subject to confirmation of
your entitlement. No initial sales charges are imposed upon Class A shares
acquired upon the reinvestment of dividends and distributions. 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 shares is the NAV next determined following
receipt of an order in proper form by the Transfer Agent, your Dealer or the
Distributor. The offering price of Class C shares is the NAV next determined
following receipt of an order in proper form by the Transfer Agent, your Dealer
or the Distributor plus a sales charge equal to 1% of the public offering price.
Redemption 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, from its own resources, sales commissions of up to
4% of the purchase price of Class B shares to Dealers, financial advisers and
other persons who sell Class B shares at the time of sale. This facilitates the
ability of the Trust to sell the Class B shares of the Funds without an initial
sales charge being deducted at the time of purchase. The Distributor anticipates
that it will recoup its advancement of sales commissions from the combination of
the CDSC and the distribution fee. In connection with the sale of Class C
shares, the Distributor will pay, partially from its own resources, Dealers,
financial advisers
    
 
                                       26
<PAGE>
   
and other persons which distribute Class C shares a sales commission of up to 2%
of the purchase price at the time of the sale. The Distributor anticipates that
it would recoup its advancement of sales commissions from the combination of the
CDSC and the distribution fee. See "How the Fund is Managed--Distributor."
    
 
   
  WAIVER OF INITIAL SALES CHARGE--CLASS C SHARES
    
 
   
  INVESTMENTS OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. Investors
may purchase Class C shares at NAV, without the initial sales charge, with the
proceeds from the redemption of shares of any unaffiliated registered investment
company which were not held through an account with any Prudential affiliate.
Such purchases must be made within 60 days of the redemption. Investors eligible
for this waiver include: (i) investors purchasing shares through an account at
Prudential Securities Incorporated; (ii) investors purchasing shares through an
ADVANTAGE Account or an Investor Account with Pruco Securities Corporation; and
(iii) investors purchasing shares through other Dealers. This waiver is not
available to investors who purchase shares directly from the Transfer Agent. You
must notify the Transfer Agent directly or through your Dealer if you are
entitled to this waiver and provide the Transfer Agent with such supporting
documents as it may deem appropriate.
    
 
HOW TO SELL YOUR SHARES
 
   
  YOU CAN REDEEM YOUR SHARES OF THE SERIES AT ANY TIME FOR CASH AT THE NAV NEXT
DETERMINED AFTER THE REDEMPTION REQUEST IS RECEIVED IN PROPER FORM (IN
ACCORDANCE WITH PROCEDURES ESTABLISHED BY THE TRANSFER AGENT IN CONNECTION WITH
INVESTORS' ACCOUNTS) BY THE DISTRIBUTOR, YOUR DEALER OR THE TRANSFER AGENT. SEE
"HOW THE FUND VALUES ITS SHARES." In certain cases, however, redemption proceeds
will be reduced by the amount of any applicable CDSC, as described below. See
"Contingent Deferred Sales Charges" below. If you are redeeming your shares
through a Dealer, your Dealer must receive your sell order before the Fund
computes its NAV for that day (I.E., 4:15 p.m., New York time) in order to
receive that day's NAV. Your Dealer will be responsible for furnishing all
necessary documentation to the Distributor and may charge you for its services
in connection with redeeming shares of the Fund.
    
 
   
  IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A WRITTEN REQUEST FOR REDEMPTION
SIGNED BY YOU EXACTLY AS THE ACCOUNT IS REGISTERED IS REQUIRED. IF YOU HOLD
CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE FACE OF THE
CERTIFICATES, MUST BE RECEIVED BY THE TRANSFER AGENT, THE DISTRIBUTOR OR YOUR
DEALER IN ORDER FOR THE REDEMPTION REQUEST TO BE PROCESSED. IF REDEMPTION IS
REQUESTED BY A CORPORATION, PARTNERSHIP, TRUST OR FIDUCIARY, WRITTEN EVIDENCE OF
AUTHORITY ACCEPTABLE TO THE TRANSFER AGENT MUST BE SUBMITTED BEFORE SUCH REQUEST
WILL BE ACCEPTED. All correspondence and documents concerning redemptions should
be sent to the Fund in care of its Transfer Agent, Prudential Mutual Fund
Services LLC, Attention: Redemption Services, P.O. Box 15010, New Brunswick, New
Jersey 08906-5010, the Distributor or your Dealer.
    
 
   
  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.
    
 
   
  PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE MADE BY CHECK WITHIN SEVEN
DAYS AFTER RECEIPT BY THE TRANSFER AGENT, THE DISTRIBUTOR OR YOUR DEALER OF THE
CERTIFICATE AND/OR WRITTEN REQUEST EXCEPT AS INDICATED BELOW. IF YOU HOLD SHARES
THROUGH A DEALER, PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE CREDITED
TO YOUR ACCOUNT AT YOUR DEALER, 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 Series of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Series fairly
to determine the value of its net assets, or (d) during any other period when
the Commission, by order, so permits: provided that applicable rules and
regulations of the Commission shall govern as to whether the conditions
prescribed in (b), (c) or (d) exist.
    
 
                                       27
<PAGE>
   
  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, WHICH MAY TAKE 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 CASHIER'S CHECK.
    
 
   
  REDEMPTION IN KIND. If the Trustees determine that it would be detrimental to
the best interests of the remaining shareholders of the Fund to make payment
wholly or partly in cash, the Fund may pay the redemption price in whole or in
part by a distribution in kind of securities from the investment portfolio of
the Series of the Fund, in lieu of cash, in conformity with applicable rules of
the Commission. Securities will be readily marketable and will be valued in the
same manner as in a regular redemption. See "How the Fund Values its Shares." If
your shares are redeemed in kind, you will incur transaction costs in converting
the assets into cash. The Fund, however, has elected to be governed by Rule
18f-1 under the Investment Company Act, under which the Fund is obligated to
redeem shares solely in cash up to the lesser of $250,000 or 1% of the NAV of
the Fund during any 90-day period for any one shareholder.
    
 
   
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Trustees
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 NAV of less
than $500 due to a redemption. The Fund will give such shareholders 60 days'
prior written notice in which to purchase sufficient additional shares to avoid
such redemption. No CDSC will be imposed on any such involuntary redemption.
    
 
   
  90-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not previously
exercised the repurchase privilege, you may reinvest any portion or all of the
proceeds of such redemption in shares of the Series at the NAV next determined
after the order is received, which must be within 90 days after the date of the
redemption. Any CDSC paid in connection with such redemption will be credited
(in shares) to your account. If less than a full repurchase is made, the credit
will be on a PRO RATA basis. You must notify the Transfer Agent, either directly
or through the Distributor or your Dealer, 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 may affect the federal tax treatment of any gain
realized upon redemption.
    
 
  CONTINGENT DEFERRED SALES CHARGES
 
   
  Redemptions of Class B shares will be subject to a CDSC declining from 5% to
zero over a six-year period. Class C shares redeemed within 18 months 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 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. See "How
to Exchange Your Shares" below.
 
                                       28

  The following table sets forth the rates of the CDSC applicable to redemptions
of Class B shares:

</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 NAV above the total amount of payments for
the purchase of Series shares made during the preceding six years (five years
for Class B shares purchased prior to January 22, 1990); then of amounts
representing the cost of shares held beyond the applicable CDSC period; and
finally, of amounts representing the cost of shares held for the longest period
of time within the applicable CDSC period.
    
 
  For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided to
redeem $500 of your investment. Assuming at the time of the redemption the NAV
had appreciated to $12 per share, the value of your Class B shares would be
$1,260 (105 shares at $12 per share). The CDSC would not be applied to the value
of the reinvested dividend shares and the amount which represents appreciation
($260). Therefore, $240 of the $500 redemption proceeds ($500 minus $260) would
be charged at a rate of 4% (the applicable rate in the second year after
purchase) for a total CDSC of $9.60.
 
  For federal income tax purposes, the amount of the CDSC will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the
redemption of shares.
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES. The CDSC will be
waived in the case of a redemption following the death or disability of a
shareholder or, in the case of a trust account, following the death or
disability of the grantor. The waiver is available for total or partial
redemptions of shares owned by a person, either individually or in joint tenancy
(with rights of survivorship), at the time of death or initial determination of
disability, provided that the shares were purchased prior to death or
disability. In addition, the CDSC will be waived on redemptions of shares held
by a Trustee of the Fund.
    
 
  SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on certain
redemptions from a Systematic Withdrawal Plan. On an annual basis, up to 12% of
the total dollar amount subject to the CDSC may be redeemed without charge. The
Transfer Agent will calculate the total amount available for this waiver
annually on the anniversary of your purchase or, for shares purchased prior to
March 1, 1997, on March 1 of the current year. The CDSC will be waived (or
reduced) on redemptions until this threshold 12% amount is reached.
 
   
  You must notify the Transfer Agent either directly or through your Dealer, at
the time of redemption, that you are entitled to waiver of the CDSC 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.
    
 
   
  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.

<PAGE>
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 NAV without the imposition of any additional sales charge.
    
 
  Since the Fund tracks amounts paid rather than the number of shares bought on
each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will be
determined on each conversion date in accordance with the following formula: (i)
the ratio of (a) the amounts paid for Class B shares purchased at least seven
years prior to the conversion date to (b) the total amount paid for all Class B
shares purchased and then held in your account (ii) multiplied by the total
number of Class B shares purchased and then held in your account. Each time any
Eligible Shares in your account convert to Class A shares, all shares or amounts
representing Class B shares then in your account that were acquired through the
automatic reinvestment of dividends and other distributions will convert to
Class A shares.
 
   
  For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different NAV's, 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 NAV of the Class A shares may be higher than that of the Class B
shares at the time of conversion. Thus, although the aggregate dollar value will
be the same, you may receive fewer Class A shares than Class B shares converted.
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 and Class C 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 Series 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 SERIES, YOU HAVE AN EXCHANGE PRIVILEGE WITH THE OTHER
SERIES OF THE FUND AND 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 OF THE SERIES
MAY BE EXCHANGED FOR CLASS A, CLASS B AND CLASS C SHARES, RESPECTIVELY, OF THE
OTHER SERIES OF THE FUND OR ANOTHER FUND ON THE BASIS OF THE RELATIVE NAV. No
    
 
                                       30
<PAGE>
   
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, Inc. 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, weekdays, except
holidays, between the hours of 8:00 A.M. and 6:00 P.M., New York time. For your
protection and to prevent fraudulent exchanges, your telephone call will be
recorded and you will be asked to provide your personal identification number. A
written confirmation of the exchange transaction will be sent to you. NEITHER
THE FUND NOR ITS AGENTS WILL BE LIABLE FOR ANY LOSS, LIABILITY OR COST WHICH
RESULTS FROM ACTING UPON INSTRUCTIONS REASONABLY BELIEVED TO BE GENUINE UNDER
THE FOREGOING PROCEDURES. All exchanges will be made on the basis of the
relative NAV of the two funds (or series) next determined after the request is
received in good order.
    
 
  IF YOU HOLD SHARES THROUGH PRUDENTIAL SECURITIES, YOU MUST EXCHANGE YOUR
SHARES BY CONTACTING YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISER.
 
  IF YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE
FACE OF THE CERTIFICATES, MUST BE RETURNED IN ORDER FOR THE SHARES TO BE
EXCHANGED. 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 PRIVILEGE. 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"
above). Under this exchange privilege, amounts representing any Class B and
Class C shares (which are not subject to a CDSC) held in such a shareholder's
account will be automatically exchanged for Class A shares 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 NAV above the total amount of
payments for the purchase of Class B or Class C shares and (3) amounts
representing Class B or Class C shares held beyond the applicable CDSC period.
Class B and Class C shareholders must notify the Transfer Agent either directly
or through their Dealer or the Distributor that they are eligible for this
special exchange privilege.
    
 
   
  The exchange privilege is not a right and may be suspended, terminated or
modified on 60 days' notice to shareholders.
    
 
   
  FREQUENT TRADING. The Fund and the other Prudential Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market timing
investment strategies and excessive trading can have on efficient portfolio
management, each Prudential Mutual Fund, including the Fund, reserves the right
to refuse purchase orders and exchanges by any person, group or commonly
controlled accounts, if, in the Manager's sole judgment, such person, group or
accounts were following a market timing strategy or were otherwise engaging in
excessive trading (Market Timers).
    
 
                                       31
<PAGE>
  To implement this authority to protect the Fund and its shareholders from
excessive trading, the Fund will reject all exchanges and purchases from a
Market Timer unless the Market Timer has entered into a written agreement with
the Fund or its affiliates pursuant to which the Market Timer has agreed to
abide by certain procedures, which include a daily dollar limit on trading. The
Fund may notify the Market Timer of rejection of an exchange or purchase order
subsequent to the day on which the order was placed.
 
SHAREHOLDER SERVICES
 
   
  In addition to the exchange privilege, as a shareholder in the Series, you can
take advantage of the following 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 Series 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
your Dealer, you should contact your Dealer.

the Series' shares in amounts as little as $50 via an automatic charge to a bank
account or brokerage account (including a Command Account). For additional
information about this service, you may contact the Distributor, your Dealer or
the Transfer Agent directly.
    
 
   
  - THE PRUTECTOR PROGRAM-OPTIONAL GROUP TERM LIFE INSURANCE. Prudential makes
available optional group term life insurance coverage to purchasers of shares of
certain Prudential Mutual Funds which are held in an eligible brokerage account.
This insurance protects the value of your mutual fund investment for your
beneficiaries against market downturns. The insurance benefit is based on the
difference at the time of the insured's death between the protected value and
the then current market value of the shares. This coverage is not available in
all states and is subject to various restrictions and limitations. For more
complete information about this program, including charges and expenses, please
contact your Prudential representative.
    
 
  - SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available to

                        DESCRIPTION OF SECURITY RATINGS
 
MOODY'S INVESTORS SERVICE
 
BOND RATINGS
 
  Aaa: Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
   
  Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group, they comprise what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than the Aaa securities.
    
 
  A: Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium-grade obligations. Factors giving security
to principal and interest are considered adequate but elements may be present
which suggest a susceptibility to impairment sometime in the future.
 
   
  Baa: Bonds which are rated Baa are considered as medium grade obligations,
(I.E., 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.
    
 
  Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
  B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
  Ca: Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.
 
  C: Bonds which are rated C are the lowest-rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.
 
SHORT-TERM RATINGS
 
  Moody's ratings for tax-exempt notes and other short-term loans are designated
Moody's Investment Grade (MIG). This distinction is in recognition of the
differences between short-term and long-term credit risk.
 
  MIG 1: Loans bearing the designation MIG 1 are of the best quality, enjoying
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.
 
  MIG 2: Loans bearing the designation MIG 2 are of high quality, with margins
of protection ample although not so large as in the preceding group.
 
                                      A-1
<PAGE>
  MIG 3: Loans bearing the designation MIG 3 are of favorable quality, with all
security elements accounted for but lacking the strength of the preceding
grades.
 
   
  MIG 4: Loans bearing the designation MIG 4 are of adequate quality. Protection
commonly regarded and required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.
    
 
   
  SG: This designation denotes speculative quality. Debt instruments in this
category lack margins of protection.

  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted.
    
 
   
  PRIME-1: Issuers rated "Prime-1" (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
    
 
   
  - Leading market positions in well-established industries.
    
 
   
  - High rates of return on funds employed.
    
 
   
  - Conservative capitalization structure with moderate reliance on debt and
  ample asset protection.
    
 
   
  - Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
    
 
   
  - Well-established access to a range of financial markets and assured
  sources of alternate liquidity.
    
 
   
  PRIME-2: Issuers rated "Prime-2" (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This normally will
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
    
 
  PRIME-3: Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term debt obligations.
 
   
  NOT PRIME: Issuers rated Not Prime do not fall within any of the Prime rating
categories.
    
 
   
STANDARD & POOR'S RATINGS GROUP
    
 
   
DEBT RATINGS
    
 
   
  AAA: An obligation rated AAA has the highest rating assigned by S&P. The
obligor's capacity to meet its financial commitment on the obligation is
extremely strong.
    
 
   
  AA: An obligation rated AA differs from the highest rated obligations only in
small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.
    
 
   
  A: An obligation rated A is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.
    
 
   
  BBB: An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.
    
 
   
  BB, B, CCC, CC AND C: Obligations rated BB, B, CCC, CC and C are regarded as
having significant speculative characteristics. BB indicates the least degree of
speculation and C the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.
    
 
                                      A-2
<PAGE>
  D: Debt rated D is in payment default. This rating is used when interest
payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period.
 
COMMERCIAL PAPER RATINGS
 
  An S&P Commercial Paper rating is a current assessment of the likelihood of
timely payment of debt considered short-term in the relevant market.
 
   
  A-1: This designation indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus sign (+) designation.
    
 
   
  A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.
    
 
  A-3: Issues carrying this designation have adequate capacity for timely
payment. They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.
 
MUNICIPAL NOTES
 
  A municipal note rating reflects the liquidity concerns and market access
risks unique to municipal notes. Municipal notes due in three years or less will
likely receive a municipal note rating, while notes maturing beyond three years
will most likely receive a long-term debt rating. Municipal notes are rated
SP-1, SP-2 or SP-3. The designation SP-1 indicates a very strong capacity to pay
principal and interest. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation. An SP-2
designation indicates a satisfactory capacity to pay principal and interest. An
SP-3 designation indicates speculative capacity to pay principal and interest.

Prudential Municipal Series Fund
(Michigan Series)

PROSPECTUS DATED NOVEMBER 2, 1998
    
- ----------------------------------------------------------------
 
Prudential Municipal Series Fund (the Fund) (Michigan Series) (the Series) is
one of thirteen series of an open-end, management investment company, or mutual
fund. This Series is diversified and is designed to provide the maximum amount
of income that is exempt from Michigan State and federal income taxes consistent
with the preservation of capital and, in conjunction therewith, the Series may
invest in debt securities with the potential for capital gain. The net assets of
the Series are invested primarily in obligations within the four highest ratings
of Moody's Investors Service, Standard & Poor's Ratings Group or another
nationally recognized statistical rating organization or in unrated obligations
which, in the opinion of the Fund's investment adviser, are of comparable
quality. The Series may, however, also invest a portion of its assets in
lower-quality municipal obligations or in non-rated securities which, in the
opinion of the Fund's investment adviser, are of comparable quality. Subject to
the limitations described herein, the Series may utilize derivatives, including
buying and selling futures contracts and options thereon for the purpose of
hedging its portfolio securities. There can be no assurance that the Series'
investment objective will be achieved. See "How the Fund Invests--Investment
Objective and Policies." The Fund's address is Gateway Center Three, 100
Mulberry Street, Newark, New Jersey 07102-4077, and its telephone number is
(800) 225-1852.
 
   
The Trustees of the Fund have recently approved a proposal to exchange the
assets and liabilities of the Series of the Fund for shares of Prudential
National Municipals Fund, Inc. (National Municipals Fund). Class A, Class B and
Class C shares of the Series would be exchanged at relative net asset value for
Class A shares of National Municipals Fund. The transfer has been approved by
the Trustees of the Fund and by the Board of Directors of National Municipals
Fund and is subject to approval by the shareholders of the Series. It is
anticipated that a proxy statement/prospectus relating to the transaction will
have been mailed to the Series' shareholders in late October 1998. EFFECTIVE
IMMEDIATELY, THE FUND WILL NO LONGER ACCEPT ORDERS TO PURCHASE OR EXCHANGE FOR
SHARES OF THE SERIES, EXCEPT FOR PURCHASES BY CERTAIN RETIREMENT AND EMPLOYEE
PLANS (EXCLUDING IRA ACCOUNTS). Existing shareholders may continue to acquire
shares through dividend reinvestment. The current redemption privilege and the
current exchange privilege of obtaining shares of other Prudential Mutual Funds
will remain in effect until the transaction is consummated. If the transaction
is not consummated, the Fund will resume accepting orders to purchase or
exchange for shares of the Series. See "Shareholder Guide--How to Buy Shares of
the Fund."
    
 
   
This Prospectus sets forth concisely the information about the Fund and the
Michigan Series that a prospective investor should know before investing and is
available at the Web site of the Prudential Insurance Company of America
(http://www.prudential.com). Additional information about the Fund has been
filed with the Securities and Exchange Commission (the Commission) in a
Statement of Additional Information dated November 2, 1998, which information is
incorporated herein by reference (is legally considered a part of this
Prospectus) and is available without charge upon request to the Fund at the
address or telephone number noted above. The Commission maintains a Web site
(http://www.sec.gov) that contains the Statement of Additional Information,
material incorporated by reference and other information regarding the Fund.

                                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 MUNICIPAL SERIES FUND?
 
    Prudential Municipal Series Fund is a mutual fund whose shares are offered
  in thirteen series, each of which operates as a separate 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,
  management investment company. Only the Michigan Series is offered through
  this Prospectus.
 
  WHAT IS THE SERIES' INVESTMENT OBJECTIVE?
 
    The Series' investment objective is to maximize current income that is
  exempt from Michigan State and federal income taxes consistent with the
  preservation of capital. It seeks to achieve this objective by investing
  primarily in Michigan State, municipal and local government obligations and
  obligations of other qualifying issuers, such as issuers located in Puerto
  Rico, the Virgin Islands and Guam, which pay income exempt, in the opinion
  of counsel, from Michigan State and federal income taxes (Michigan
  Obligations). There can be no assurance that the Series' investment
  objective will be achieved. See "How the Fund Invests--Investment Objective
  and Policies" at page 8.
 
  WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?
 
   
    In seeking to achieve its investment objective, the Series will invest at
  least 80% of the value of its total assets in Michigan Obligations. This
  degree of investment concentration makes the Series particularly susceptible
  to factors adversely affecting issuers of Michigan Obligations. See "How the
  Fund Invests--Investment Objective and Policies-- Special Considerations" at
  page 13. The Series may invest up to 30% of its total assets in high yield
  securities, commonly known as junk bonds, which may be considered
  speculative and are subject to the risk of an issuer's inability to meet
  principal and interest payments on the obligations as well as price
  volatility. See "How the Fund Invests--Investment Objective and
  Policies--Risk Factors Relating to Investing in High Yield Municipal
  Obligations" at page 11. To hedge against changes in interest rates, the
  Series may also purchase put options and engage in transactions involving
  derivatives, including financial futures contracts and options thereon. See
  "How the Fund Invests--Investment Objective and Policies--Futures Contracts
  and Options Thereon" at page 12. As with an investment in any mutual fund,
  an investment in this Series can decrease in value and you can lose money.
    
 
  WHO MANAGES THE FUND?
 
   
    Prudential Investments Fund Management LLC (PIFM 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 Series' average daily net assets. As of September 30, 1998,
  PIFM served as manager or administrator to 66 investment companies,
  including 44 mutual funds, with aggregate assets of approximately $67
  billion. The Prudential Investment Corporation (PIC, the Subadviser or the
  investment adviser), furnishes investment advisory services in connection
  with the management of the Fund under a Subadvisory Agreement with PIFM. See
  "How the Fund is Managed--Manager" at page 14.
    
 
  WHO DISTRIBUTES THE SERIES' SHARES?
 
   
    Prudential Investment Management Services LLC (the Distributor) acts as
  the Distributor of the Series' Class A, Class B and Class C shares and is
  paid a distribution and service fee with respect to Class A shares at the
  annual rate of .25 of 1% of the average daily net assets of the Class A
  shares and is paid a distribution and service fee with respect to Class B
  shares at the annual rate of .50 of 1% of the average daily net assets of
  the Class B shares and is paid an annual distribution and service fee with
  respect to Class C shares 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 15.
    
 
                                       2
<PAGE>
  WHAT IS THE MINIMUM INVESTMENT?
 
   
    The minimum initial investment is $1,000 for Class A and Class B shares
  and $2,500 for Class C shares. The minimum subsequent investment is $100 for
  Class A, Class B and Class C shares. There is no minimum investment
  requirement for certain employee savings plans. For purchases made through
  the Automatic Investment Plan, the minimum initial and subsequent investment
  is $50. See "Shareholder Guide--How to Buy Shares of the Fund" at page 22
  and "Shareholder Guide--Shareholder Services" at page 31.
    
 
  HOW DO I PURCHASE SHARES?
 
   
    You may purchase shares of the Series through the Distributor or brokers
  or dealers that have entered into agreements to act as participating or
  introducing brokers for the Distributor (Dealers) or directly from the Fund
  through its transfer agent, Prudential Mutual Fund Services LLC. (PMFS or
  the Transfer Agent). In each case, sales are made at the net asset value per
  share (NAV) next determined after receipt of your purchase order by the
  Transfer Agent, a Dealer or the Distributor plus a sales charge, which may
  be imposed at the time of purchase, on a deferred basis, or both. Class A
  shares are sold with a front-end sales charge. Class B shares are subject to
  a contingent-deferred sales charge (CDSC). Class C shares are sold with a
  low front-end sales charge, but are also subject to a CDSC. Dealers may
  charge their customers a separate fee for handling purchase transactions.
  See "How the Fund Values its Shares" at page 17 and "Shareholder Guide--How
  to Buy Shares of the Fund" at page 22.
    
 
  WHAT ARE MY PURCHASE ALTERNATIVES?
 
    The Series 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 with an initial sales charge of 1% of the
                         offering price and are also subject to a CDSC of 1%
                         on redemptions for a period of 18 months after
                         purchase. Class C shares are subject to higher
                         ongoing distribution-related expenses than Class A
                         shares but, unlike Class B shares, do not convert
                         to another class.
    
 
    See "Shareholder Guide--Alternative Purchase Plan" at page 23.
 
  HOW DO I SELL MY SHARES?
 
   
    You may redeem your shares at any time at the NAV next determined after
  your Dealer, the Distributor or the Transfer Agent receives your sell order.
  The proceeds of redemptions of Class B and Class C shares may be subject to
  a CDSC. Dealers may charge their customers a separate fee for handling sale
  transactions. See "Shareholder Guide--How to Sell Your Shares" at page 26.
    
 
  HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
 
   
    The Series expects to declare daily and pay monthly dividends of net
  investment income, if any, and make distributions of any net capital gains
  at least annually. Dividends and distributions will be automatically
  reinvested in additional shares of the Series at NAV without a sales charge
  unless you request that they be paid to you in cash. See "Taxes, Dividends
  and Distributions" at page 18.

EXAMPLE
You would pay the following expenses on
  a $1,000 investment, assuming (1) 5%
  annual return and (2) redemption at
  the end of each time period:
    Class A............................  $  41   $   63   $   87   $   157
    Class B............................  $  63   $   72   $   82   $   149
    Class C............................  $  36   $   59   $   95   $   195
You would pay the following expenses on
  the same investment, assuming no
  redemption:
    Class A............................  $  41   $   63   $   87   $   157
    Class B............................  $  13   $   42   $   72   $   149
    Class C............................  $  26   $   59   $   95   $   195
</TABLE>
    
 
   
   THE EXAMPLES 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
   various costs and expenses that an investor in the Series will bear,
   whether directly or indirectly. For more complete descriptions of the
   various costs and expenses, see "How the Fund is Managed." The above
   examples are based on restated data for the Series' fiscal year ended
   August 31, 1998. "Other Expenses" includes Trustees' and professional
   fees, registration fees, reports to shareholders and 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."
    
 
   
+  Dealers independently may charge additional fees for shareholder transactions
       or advisory services. 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 Series may
       not exceed 6.25% of total gross sales, subject to certain exclusions.
       This 6.25% limitation is imposed on each class of the Series rather than
       on a per shareholder basis. Therefore, long-term shareholders of the
       Series 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, Class B and Class C Distribution and Service Plans
       provide that the Fund may pay a distribution fee of up to .30 of 1%, .50
       of 1% and 1% per annum of the average daily net assets of the Class A,
       Class B and Class C shares, respectively, the Distributor may voluntarily
       limit its distribution fees. Presently the Distributor limits its
       distribution fees with respect to the Class A, Class B and Class C shares
       of the Series to no more than .10 of 1%, .10 of 1% and .25 of 1% of the
       average daily net asset value of the Class A, Class B and Class C shares,
       respectively. This voluntary limitation may be modified or terminated at
       any time without notice. The Distributor anticipates modifying its
       present limitation for Class A and Class C shares so that, in the future,
       the Fund will pay distribution fees of .25% and .75%, respectively, and
       eliminating its present limitation for Class B shares so that, in the
       future, the Fund will pay distribution fees of .50%. Total Fund Operating
       Expenses of the Class A and Class C shares without any limitations would
       be 1.12% and 1.82%, respectively. See "How the Fund is
       Managed--Distributor."

                              HOW THE FUND INVESTS
 
INVESTMENT OBJECTIVE AND POLICIES
 
  PRUDENTIAL MUNICIPAL SERIES FUND (THE FUND) IS AN OPEN-END, MANAGEMENT
INVESTMENT COMPANY, OR MUTUAL FUND, CONSISTING OF THIRTEEN SEPARATE SERIES. EACH
OF THESE SERIES IS MANAGED INDEPENDENTLY. THE MICHIGAN SERIES (THE SERIES) IS
DIVERSIFIED AND ITS INVESTMENT OBJECTIVE IS TO MAXIMIZE CURRENT INCOME THAT IS
EXEMPT FROM MICHIGAN STATE AND FEDERAL INCOME TAXES CONSISTENT WITH THE
PRESERVATION OF CAPITAL AND, IN CONJUNCTION THEREWITH, THE SERIES MAY INVEST IN
DEBT SECURITIES WITH THE POTENTIAL FOR CAPITAL GAIN. See "Investment Objectives
and Policies" in the Statement of Additional Information.
 
  THE SERIES' INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE, MAY
NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE SERIES'
OUTSTANDING VOTING SECURITIES AS DEFINED IN THE INVESTMENT COMPANY ACT OF 1940,
AS AMENDED (THE INVESTMENT COMPANY ACT). THE SERIES' POLICIES THAT ARE NOT
FUNDAMENTAL MAY BE MODIFIED BY THE TRUSTEES.
 
  THE SERIES WILL INVEST PRIMARILY IN MICHIGAN STATE, MUNICIPAL AND LOCAL
GOVERNMENT OBLIGATIONS AND OBLIGATIONS OF OTHER QUALIFYING ISSUERS, SUCH AS
ISSUERS LOCATED IN PUERTO RICO, THE VIRGIN ISLANDS AND GUAM, WHICH PAY INCOME
EXEMPT, IN THE OPINION OF COUNSEL, FROM MICHIGAN STATE AND FEDERAL INCOME TAXES
(MICHIGAN OBLIGATIONS). THERE CAN BE NO ASSURANCE THAT THE SERIES WILL BE ABLE
TO ACHIEVE ITS INVESTMENT OBJECTIVE.
 
  As with an investment in any mutual fund, an investment in this Series can
decrease and you can lose money.
 
   
  Interest on certain municipal obligations may be a preference item for
purposes of the federal alternative minimum tax. The Series may invest without
limit in municipal obligations that are private activity bonds (as defined in
the Internal Revenue Code) the interest on which would be a preference item for
purposes of the federal alternative minimum tax. See "Taxes, Dividends and
Distributions." Under Michigan law, dividends paid by the Series are exempt from
Michigan income tax and single business tax for resident individuals and
corporations to the extent they are derived from interest payments on Michigan
Obligations. Michigan Obligations could include general obligation bonds of the
State, counties, cities, towns, etc., revenue bonds of utility systems,
highways, bridges, port and airport facilities, colleges, hospitals, etc., and
industrial development and pollution control bonds. The Series will invest in
long-term obligations, and the dollar-weighted average maturity of the Series'
portfolio will generally range between 10-20 years. The Series also may invest
in certain short-term, tax-exempt notes such as Tax Anticipation Notes, Revenue
Anticipation Notes, Bond Anticipation Notes, Construction Loan Notes and
variable and floating rate demand notes.
    
 
   
  Generally, municipal obligations with longer maturities produce higher yields
and are subject to greater price fluctuations as a result of changes in interest
rates (market risk) than municipal obligations with shorter maturities. The
prices of municipal obligations vary inversely with interest rates. Interest
rates are currently much lower than in recent years. As a general matter, bond
prices and the Series' NAV will vary inversely with interest rate fluctuations.
If rates were to rise sharply, the prices of bonds in the Series' portfolio
might be adversely affected.
    
 
  THE SERIES MAY INVEST ITS ASSETS IN FLOATING RATE AND VARIABLE RATE
SECURITIES, INCLUDING PARTICIPATION INTERESTS THEREIN AND INVERSE FLOATERS.
There is no limit on the amount of such securities that the Series may purchase.
Floating rate securities normally have a rate of interest which is set as a
specific percentage of a designated base rate, such as the rate on Treasury
bonds or bills or the prime rate at a major commercial bank. The interest rate
on floating rate securities changes periodically when there is a change in the
designated base interest rate. Variable rate securities provide for a specified
periodic adjustment in the interest rate based on prevailing market rates and
generally would allow the Series to demand payment of the obligation on short
notice at par plus accrued interest, which amount may be more or less than the
amount the Series paid for them. An inverse floater is a debt instrument with a
floating or variable interest rate that moves in the opposite direction of the
 
                                       8
<PAGE>
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 the inverse floaters is relatively new.
 
  THE SERIES 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) or the
acquisition of equipment. 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 Trustees. Municipal lease obligations will not be considered illiquid for
purposes of the Series' 15% limitation on illiquid securities provided the
investment adviser determines that there is a readily available market for such
securities. See "Other Investments and Policies--Illiquid Securities" below.
 
   
  THE SERIES WILL INVEST AT LEAST 70% OF ITS TOTAL ASSETS IN MICHIGAN
OBLIGATIONS WHICH, AT THE TIME OF PURCHASE, ARE RATED WITHIN THE FOUR HIGHEST
QUALITY GRADES AS DETERMINED BY MOODY'S INVESTORS SERVICE (MOODY'S) (CURRENTLY
Aaa, Aa, A, Baa FOR BONDS, MIG 1, MIG 2, MIG 3, MIG 4 FOR NOTES AND PRIME-1 FOR
COMMERCIAL PAPER), STANDARD & POOR'S RATINGS GROUP (S&P) (CURRENTLY AAA, AA, A,
BBB FOR BONDS, SP-1, SP-2 FOR NOTES AND A-1 FOR COMMERCIAL PAPER) OR ANOTHER
NATIONALLY RECOGNIZED STATISTICAL RATING ORGANIZATION (NRSRO) OR, IF UNRATED,
WILL POSSESS CREDITWORTHINESS, IN THE OPINION OF THE INVESTMENT ADVISER,
COMPARABLE TO SUCH INVESTMENT GRADE RATED SECURITIES.
    
 
   
  THE SERIES MAY ALSO INVEST UP TO 30% OF ITS TOTAL ASSETS IN MICHIGAN
OBLIGATIONS RATED BELOW Baa BY MOODY'S OR BELOW BBB BY S&P, OR A COMPARABLE
RATING OF ANOTHER NRSRO OR, IF NON-RATED, OF COMPARABLE QUALITY, IN THE OPINION
OF THE FUND'S INVESTMENT ADVISER, BASED ON ITS CREDIT ANALYSIS. Securities rated
Baa by Moody's and BBB by S&P are described as being investment grade but are
also characterized as having speculative characteristics. Securities rated below
Baa by Moody's and below BBB by S&P are considered speculative. See "Description
of Security Ratings" in the Appendix. Such lower-rated high yield securities are
commonly referred to as junk bonds. Such securities generally offer a higher
current yield than those in the higher rating categories but may also involve
greater price volatility and risk of loss of principal and income. The
investment adviser will attempt to manage risk and enhance yield through credit
analysis and careful security selection. See "Risk Factors Relating to Investing
in High Yield Municipal Obligations" below. Subsequent to its purchase by the
Series, a municipal obligation may be assigned a lower rating or cease to be
rated. Such an event would not require the elimination of the issue from the
portfolio, but the investment adviser will consider such an event in determining
whether the Series should continue to hold the security in its portfolio. Many
issuers of lower-quality bonds choose not to have their obligations rated and
the Series may invest in such unrated securities. Investors should carefully
consider the relative risks associated with investments in securities which
carry lower ratings and in comparable non-rated securities.
    
 
   
  During the year ended August 31, 1998, the monthly dollar weighted average
ratings of the debt obligations held by the Series, expressed as a percentage of
the Series' total assets, were as follows:

  From time to time, the Series may own the majority of a municipal issue. Such
majority-owned holdings may present market and credit risks.
 
  The Series may purchase Michigan Obligations which, in the opinion of the
investment adviser, offer the opportunity for capital appreciation. This may
occur, for example, when the investment adviser believes that the issuer of a
particular Michigan Obligation might receive an upgraded credit standing,
thereby increasing the market value of the bonds it has issued or when the
investment adviser believes that interest rates might decline.
 
  UNDER NORMAL MARKET CONDITIONS, THE SERIES WILL ATTEMPT TO INVEST
SUBSTANTIALLY ALL OF THE VALUE OF ITS ASSETS IN MICHIGAN OBLIGATIONS. As a
matter of fundamental policy, during normal market conditions the Series' assets
will be invested so that at least 80% of the income will be exempt from Michigan
State and federal income taxes or the Series will have at least 80% of its total
assets invested in Michigan Obligations. During abnormal market conditions or to
provide liquidity, the Series may hold cash or cash equivalents or investment
grade taxable obligations, including obligations that are exempt from federal,
but not state, taxation and the Series may invest in tax-free cash equivalents,
such as floating rate demand notes, tax-exempt commercial paper and general
obligation and revenue notes or in taxable cash equivalents, such as
certificates of deposit, bankers acceptances, time deposits or other short-term
taxable investments such as repurchase agreements. When, in the opinion of the
investment adviser, abnormal market conditions require a temporary defensive
position, the Series may invest more than 20% of the value of its assets in debt
securities other than Michigan Obligations or may invest its assets so that more
than 20% of the income is subject to Michigan State or federal income taxes. The
Series will treat an investment in a municipal bond refunded with escrowed U.S.
Government securities as U.S. Government securities for purposes of the
Investment Company Act's diversification requirements provided certain
conditions are met. See "Investment Objectives and Policies--In General" in the
Statement of Additional Information.
 
   
  THE SERIES MAY ACQUIRE PUT OPTIONS (PUTS) GIVING THE SERIES THE RIGHT TO SELL
SECURITIES HELD IN THE SERIES' PORTFOLIO AT A SPECIFIED EXERCISE PRICE ON A
SPECIFIED DATE. Such puts may be acquired for the purpose of protecting the
Series from a possible decline in the market value of the security to which the
put applies in the event of interest rate fluctuations or, in the case of
liquidity puts, for the purpose of shortening the effective maturity of the
underlying security. The aggregate value of premiums paid to acquire puts held
in the Series' portfolio (other than liquidity puts) may not exceed 10% of the
NAV of the Series. The acquisition of a put may involve an additional cost to
the Series by payment of a premium for the put, by payment of a higher purchase
price for securities to which the put is attached or through a lower effective
interest rate.
    
 
  In addition, there is a credit risk associated with the purchase of puts in
that the issuer of the put may be unable to meet its obligation to purchase the
underlying security. Accordingly, the Series will acquire puts only under the
following circumstances: (1) the put is written by the issuer of the underlying
security and such security is rated within the four highest quality grades as
determined by an NRSRO; or (2) the put is written by a person other than the
issuer of the underlying security and such person has securities outstanding
which are rated within such four highest quality grades; or (3) the put is
backed by a letter of credit or similar financial guarantee issued by a person
having securities outstanding which are rated within the two highest quality
grades of an NRSRO.
 
   
  THE SERIES 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 the securities take place at a later date. During the period between
purchase and settlement, no interest accrues to the economic benefit of the
purchaser. In the case of purchases by the Series, the price that the Series 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 Series 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 Series makes the commitment to purchase a
municipal obligation on a when-issued or delayed delivery basis, it will record
the transaction and reflect the value of the obligation each day in determining
its NAV. This value may fluctuate from day to day in the same manner as
    
 
                                       10
<PAGE>
   
values of municipal obligations otherwise held by the Series. If the seller
defaults in the sale, the Series could fail to realize the appreciation, if any,
that had occurred. The Series will establish a segregated account in which it
will maintain cash or other liquid assets, equal or greater in value to its
commitments for when-issued or delayed delivery securities.
    
 
  THE SERIES MAY ALSO PURCHASE MUNICIPAL FORWARD CONTRACTS. A municipal forward
contract is a municipal security which is purchased on a when-issued basis with
delivery taking place up to five years from the date of purchase. No interest
will accrue on the security prior to the delivery date. The investment adviser
will monitor the liquidity, value, credit quality and delivery of the security
under the supervision of the Trustees.
 
  THE SERIES MAY PURCHASE SECONDARY MARKET INSURANCE ON MICHIGAN OBLIGATIONS
WHICH IT HOLDS OR ACQUIRES. Secondary market insurance would be reflected in the
market value of the municipal obligation purchased and may enable the Series 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 Michigan Obligations held by the Series 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 NAV of the
shares of the Series.
    
 
   
  RISK FACTORS RELATING TO INVESTING IN HIGH YIELD MUNICIPAL OBLIGATIONS.
FIXED-INCOME SECURITIES ARE SUBJECT TO THE RISK OF AN ISSUER'S INABILITY TO MEET
PRINCIPAL AND INTEREST PAYMENTS ON THE OBLIGATIONS (CREDIT RISK) AND MAY ALSO BE
SUBJECT TO PRICE VOLATILITY DUE TO SUCH FACTORS AS INTEREST RATE SENSITIVITY,
MARKET PERCEPTION OF THE CREDITWORTHINESS OF THE ISSUER AND GENERAL MARKET
LIQUIDITY (MARKET RISK). Lower-rated or unrated (I.E., high yield) securities,
commonly known as junk bonds, are more likely to react to developments affecting
market and credit risk than are more highly rated securities, which react
primarily to movements in the general level of interest rates. The investment
adviser will perform its own investment analysis and will not rely principally
on the ratings assigned by the rating services, although such ratings will be
considered by the investment adviser. The investment adviser will consider,
among other things, credit risk and market risk, as well as the financial
history and condition, the prospects and the management of an issuer in
selecting securities for the Series' portfolio. The achievement of the Series'
investment objective may be more dependent on the investment adviser's credit
analysis than is the case when investing in only higher quality bonds. Investors
should carefully consider the relative risks of investing in high yield
municipal obligations and understand that such securities are not generally
meant for short-term investing and that yields on junk bonds will fluctuate over
time.
    
 
   
  The amount of high yield securities outstanding has proliferated recently in
conjunction with the decline in creditworthiness of many obligors on municipal
debt, particularly health care providers and certain governmental bodies. An
economic downturn could severely affect the ability of highly leveraged issuers
to service their debt obligations or to repay their obligations upon maturity.
Furthermore, changes in economic conditions and other circumstances are more
likely to lead to a weakened capacity to make principal and interest payments
than in the case of higher grade bonds. In addition, the secondary market for
high yield securities, which is concentrated in relatively few market makers,
may not be as liquid as the secondary market for more highly rated securities
and, from time to time, it may be more difficult to value high yield securities
than more highly rated securities, and the judgment of the Board of Trustees and
the investment adviser may play a greater role in valuation because there is
less reliable objective data available. Under adverse market or economic
conditions, the secondary market for high yield securities could contract
further, independent of any specific adverse changes in the condition of a
particular issuer. As a result, the investment adviser could find it more
difficult to sell these securities or may be able to sell the securities only at
prices lower than if such securities were widely traded. Prices realized upon
the sale of such lower rated or unrated securities, under these circumstances,
may be less than the prices used in calculating the Series' NAV. If the
investment adviser becomes involved in activities such as reorganizations of
obligors of troubled investments held by the Series, this may prevent the Series
from disposing of the securities, due to its possession of material, non-public
information concerning the obligor.
    
 
                                       11
<PAGE>
   
  LOWER-RATED OR UNRATED DEBT OBLIGATIONS ALSO PRESENT RISKS BASED ON PAYMENT
EXPECTATIONS. If an issuer calls the obligation for redemption, the Series may
have to replace the security with a lower-yielding security, resulting in a
decreased return for investors. If the Series experiences unexpected net
redemptions, it may be forced to sell its higher rated securities, resulting in
a decline in the overall credit quality of the portfolio and increasing the
exposure of the Series to the risks of high yield securities.
    
 
  FUTURES CONTRACTS AND OPTIONS THEREON
 
   
  THE SERIES IS AUTHORIZED TO PURCHASE AND SELL CERTAIN DERIVATIVES, INCLUDING
FINANCIAL FUTURES CONTRACTS (FUTURES CONTRACTS) AND OPTIONS THEREON FOR THE
PURPOSE OF HEDGING ITS PORTFOLIO SECURITIES AGAINST FLUCTUATIONS IN VALUE CAUSED
BY CHANGES IN PREVAILING MARKET INTEREST RATES AND HEDGING AGAINST INCREASES IN
THE COST OF SECURITIES THE SERIES INTENDS TO PURCHASE. THE SUCCESSFUL USE OF
FUTURES CONTRACTS AND OPTIONS THEREON BY THE SERIES INVOLVES ADDITIONAL
TRANSACTION COSTS, IS SUBJECT TO VARIOUS RISKS AND DEPENDS UPON THE INVESTMENT
ADVISER'S ABILITY TO PREDICT THE DIRECTION OF THE MARKET (INCLUDING INTEREST
RATES). THE SERIES, AND THUS INVESTORS, MAY LOSE MONEY THROUGH ANY UNSUCCESSFUL
USE OF THESE STRATEGIES.
    
 
  A FUTURES CONTRACT OBLIGATES THE SELLER OF THE CONTRACT TO DELIVER TO THE
PURCHASER OF THE CONTRACT CASH EQUAL TO A SPECIFIC DOLLAR AMOUNT TIMES THE
DIFFERENCE BETWEEN THE VALUE OF A SPECIFIC FIXED-INCOME SECURITY OR INDEX AT THE
CLOSE OF THE LAST TRADING DAY OF THE CONTRACT AND THE PRICE AT WHICH THE
AGREEMENT IS MADE. No physical delivery of the underlying securities is made.
The Series will engage in transactions in only those futures contracts and
options thereon that are traded on a commodities exchange or a board of trade.
 
   
  THE SERIES INTENDS TO ENGAGE IN FUTURES CONTRACTS AND OPTIONS THEREON AS A
HEDGE AGAINST CHANGES, RESULTING FROM MARKET CONDITIONS, IN THE VALUE OF
SECURITIES WHICH ARE HELD IN THE SERIES' PORTFOLIO OR WHICH THE SERIES INTENDS
TO PURCHASE, IN ACCORDANCE WITH THE RULES AND REGULATIONS OF THE COMMODITY
FUTURES TRADING COMMISSION (CFTC). The Series also intends to engage in such
transactions when they are economically appropriate for the reduction of risks
inherent in the ongoing management of the Series.
    
 
   
  THE SERIES MAY NOT PURCHASE OR SELL FUTURES CONTRACTS OR OPTIONS THEREON IF,
IMMEDIATELY THEREAFTER, (I) THE SUM OF INITIAL AND NET CUMULATIVE VARIATION
MARGIN ON OUTSTANDING FUTURES CONTRACTS, TOGETHER WITH PREMIUMS PAID FOR OPTIONS
THEREON, WOULD EXCEED 20% OF THE TOTAL ASSETS OF THE SERIES, OR (II) IN THE CASE
OF RISK MANAGEMENT TRANSACTIONS, THE SUM OF THE AMOUNT OF INITIAL MARGIN
DEPOSITS ON THE SERIES' FUTURES POSITIONS AND PREMIUMS PAID FOR OPTIONS THEREON
WOULD EXCEED 5% OF THE LIQUIDATION VALUE OF THE SERIES' TOTAL ASSETS. There are
no limitations on the percentage of the portfolio which may be hedged and no
limitations on the use of the Series' assets to cover futures contracts and
options thereon, except that the aggregate value of the obligations underlying
put options will not exceed 50% of the Series' assets.
    
 
  Currently, futures contracts are available on several types of fixed-income
securities, including U.S. Treasury bonds and notes, three-month U.S. Treasury
bills and Eurodollars. Futures contracts are also available on a municipal bond
index, based on THE BOND BUYER Municipal Bond Index, an index of 40 actively
traded municipal bonds. The Series may also engage in transactions in other
futures contracts that become available, from time to time, in other
fixed-income securities or municipal bond indices and in other options on such
contracts if the investment adviser believes such contracts and options would be
appropriate for hedging the Series' portfolio.
 
  THERE CAN BE NO ASSURANCE THAT VIABLE MARKETS WILL CONTINUE OR THAT A LIQUID
SECONDARY MARKET WILL EXIST TO TERMINATE ANY PARTICULAR FUTURES CONTRACT AT ANY
SPECIFIC TIME. If it is not possible to close a futures position entered into by
the Series, the Series will continue to be required to make daily cash payments
of variation margin in the event of adverse price movements. In such a
situation, if the Series had insufficient cash, it might have to sell portfolio
securities to meet daily variation margin requirements at a time when it might
be disadvantageous to do so. The inability to close futures positions also could
have an adverse impact on the ability of the Series to hedge effectively. There
is also a risk of loss by the Series of margin deposits in the event of
bankruptcy of a broker with whom the Series has an open position in a futures
contract.
 
                                       12
<PAGE>
  THE SUCCESSFUL USE OF FUTURES CONTRACTS AND OPTIONS THEREON BY THE SERIES IS
SUBJECT TO VARIOUS ADDITIONAL RISKS. Any use of futures transactions involves
the risk of imperfect correlation in movements in the price of futures contracts
and movements in interest rates and, in turn, the prices of the securities that
are the subject of the hedge. If the price of the futures contract moves more or
less than the price of the security that is the subject of the hedge, the Series
will experience a gain or loss that will not be completely offset by movements
in the price of the security. The risk of imperfect correlation is greater where
the securities underlying futures contracts are taxable securities (rather than
municipal securities), are issued by companies in different market sectors or
have different maturities, ratings or geographic mixes than the security being
hedged. In addition, the correlation may be affected by additions to or
deletions from the index which serves as the basis for a futures contract.
Finally, if the price of the security that is subject to the hedge were to move
in a favorable direction, the advantage to the Series would be partially offset
by the loss incurred on the futures contract.
 
  SPECIAL CONSIDERATIONS
 
   
  BECAUSE THE SERIES WILL INVEST AT LEAST 80% OF THE VALUE OF ITS TOTAL ASSETS
IN MICHIGAN OBLIGATIONS AND BECAUSE IT SEEKS TO MAXIMIZE INCOME DERIVED FROM
MICHIGAN OBLIGATIONS, IT IS MORE SUSCEPTIBLE TO FACTORS ADVERSELY AFFECTING
ISSUERS OF MICHIGAN OBLIGATIONS THAN IS A COMPARABLE MUNICIPAL BOND MUTUAL FUND
THAT IS NOT CONCENTRATED IN SUCH OBLIGATIONS TO THIS DEGREE. Michigan is a
highly industrialized state with an economy principally dependent upon three
sectors: manufacturing (particularly durable goods, automotive products and
office equipment), tourism and agriculture. Michigan's recovery from the effects
of a downturn in the automotive industry in the late 1980's has proved to be
robust. At the end of calendar 1997, the employment levels had reached an
all-time high, and total wage and salary employment is projected to grow 1.7% in
1998 and 0.8% in 1999. This growth reflects the ongoing diversification of the
Michigan economy. At the end of calendar 1997, the unemployment rate in Michigan
had fallen to 4.2%, and it is projected to average 4.1% in 1998 and 4.4% in
1999, continuing the recent trend of being below the national average.
Michigan's economy is among the most cyclical of all the states and remains
dependent on domestic vehicle production and durable goods consumption. For
fiscal 1995, 1996 and 1997, the State achieved budget surpluses of $82 million,
$197 million and $13 million, respectively. Fiscal 1998 General Fund revenues
and expenditures are expected to be $8,590 million and $8,602 million,
respectively. Current projections are that the unreserved balance of the State's
Budget Stabilization Fund was $646 million at the end of fiscal year 1997.
    
 
  The market value and the marketability of Michigan Obligations may be affected
adversely by the same factors that affect Michigan's economy generally. If
either Michigan or any of its local governmental entities is unable to meet its
financial obligations, the income derived by the Series, the ability to preserve
or realize appreciation of the Series' capital and the Series' liquidity could
be adversely affected. See "Investment Objectives and Policies--Special
Considerations Regarding Investments in Tax-Exempt Securities" in the Statement
of Additional Information.
 
OTHER INVESTMENTS AND POLICIES
 
  REPURCHASE AGREEMENTS
 
   
  The Series may on occasion enter into repurchase agreements whereby the seller
of a security agrees to repurchase that security from the Series at a mutually
agreed-upon time and price. The period of maturity is usually quite short,
possibly overnight or a few days, although it may extend over a number of
months. The resale price is in excess of the purchase price, reflecting an
agreed-upon rate of return effective for the period of time the Series' money is
invested in the repurchase agreement. The Series' repurchase agreements will at
all times be fully collateralized in an amount at least equal to the resale
price. The instruments held as collateral are valued daily and if the value of
the instruments declines, the Series will require additional collateral. If the
seller defaults and the value of the collateral securing the repurchase
agreement declines, the Series may incur a loss. The Series participates in a
joint repurchase account with other investment companies managed by PIFM
pursuant to an order of the Commission.
    
 
                                       13
<PAGE>
  BORROWING
 
  The Series 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) for temporary, extraordinary
or emergency purposes or for the clearance of transactions. The Series may
pledge up to 33 1/3% of the value of its total assets to secure these
borrowings. The Series will not purchase portfolio securities if its borrowings
exceed 5% of its total assets.
 
  PORTFOLIO TURNOVER
 
   
  The Series does not expect to trade in securities for short-term gain. It is
anticipated that the annual portfolio turnover rate will not exceed 150%. The
portfolio turnover rate is calculated by dividing the lesser of sales or
purchases of portfolio securities by the average monthly value of the portfolio
securities, excluding securities having a maturity at the date of purchase of
one year or less. High portfolio turnover of a Series may involve
correspondingly greater brokerage commissions and other transaction costs, which
will be borne directly by that Series. In addition, high portfolio turnover may
result in increased short-term capital gains, which, when distributed to
shareholders, are treated as ordinary income. See "Taxes, Dividends and
Distributions."
    
 
  ILLIQUID SECURITIES
 
   
  The Series may hold up to 15% of its net assets in illiquid securities
including repurchase agreements which have a maturity of longer than seven days,
securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable. Securities,
including restricted securities eligible for resale pursuant to Rule 144A under
the Securities Act of 1933, as amended (the Securities Act), privately placed
commercial paper and 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 restricted securities
under the supervision of the Trustees. The Series' investment in Rule 144A
securities could have the effect of increasing illiquidity to the extent that
qualified institutional buyers become, for a limited time, uninterested in
purchasing Rule 144A securities. See "Investment Objectives and
Policies--Illiquid Securities" and "Investment Restrictions" in the Statement of
Additional Information. Repurchase agreements subject to demand are deemed to
have a maturity equal to the notice period.
    
 
INVESTMENT RESTRICTIONS
 
  The Series 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
Series' outstanding voting securities, as defined in the Investment Company Act.
See "Investment Restrictions" in the Statement of Additional Information.
 
                            HOW THE FUND IS MANAGED

  PIFM may from time to time agree to waive all or a portion of its management
fee and subsidize all or a portion of the operating expenses of the Series. Fee
waivers and expense subsidies will increase the Series' yield and total return.
The Series is not required to reimburse PIFM for such management fee waiver. See
"Performance Information" in the Statement of Additional Information and "Fund
Expenses."
    
 
DISTRIBUTOR
 
   
  PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC (THE DISTRIBUTOR), GATEWAY
CENTER THREE, 100 MULBERRY STREET, NEWARK, NEW JERSEY 07102-4077, IS A LIMITED
LIABILITY COMPANY ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND SERVES
AS THE DISTRIBUTOR OF THE SHARES OF THE SERIES. IT IS A WHOLLY-OWNED SUBSIDIARY
OF PRUDENTIAL. Prudential Securities Incorporated (Prudential Securities), One
Seaport Plaza, New York, New York 10292, previously served as distributor of the
Series' shares. 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, COLLECTIVELY, THE PLANS) ADOPTED BY THE FUND UNDER
RULE 12b-1 UNDER THE INVESTMENT COMPANY ACT AND A DISTRIBUTION AGREEMENT (THE
DISTRIBUTION AGREEMENT), THE DISTRIBUTOR INCURS THE EXPENSES OF DISTRIBUTING THE
CLASS A, CLASS B AND CLASS C SHARES OF THE SERIES. These expenses include
commissions and account servicing fees paid to, or on account of Dealers or
financial institutions which have entered into agreements with the Distributor,
advertising expenses, the cost of printing and mailing prospectuses to potential
investors and indirect and overhead costs of the Distributor associated with the
sale of Series shares, including lease, utility, communications and sales
promotion expenses. Certain Dealers are paid higher fees than others with
respect to Class A shares pursuant to separate agreements with the Distributor.
    
 
                                       15
<PAGE>
  Under the Plans, the Series 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 Series will
not be obligated to pay any additional expenses. If the Distributor's expenses
are less than such distribution and service fees, it will retain its full fees
and realize a profit.
 
   
  The distribution and/or service fees may also be used by the Distributor to
compensate on a continuing basis Dealers in consideration for the distribution,
marketing, administrative and other services and activities provided by Dealers
with respect to the promotion of the sale of the Series' shares and the
maintenance of related shareholder accounts.
    
 
   
  UNDER THE CLASS A PLAN, THE SERIES MAY PAY THE DISTRIBUTOR FOR ITS
DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS A SHARES AT AN ANNUAL RATE
OF UP TO .30 OF 1% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS A SHARES OF THE
SERIES. 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. The Distributor has
voluntarily limited 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. This
voluntary limitation may be modified or terminated at any time without notice.
    
 
   
  UNDER THE CLASS B AND CLASS C PLANS, THE SERIES MAY PAY THE DISTRIBUTOR 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 the Distributor 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 the Distributor 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. The Distributor
has voluntarily limited its distribution-related fees payable under the Class B
and Class C Plans to .10 of 1% and .25 of 1% of the average daily net assets of
the Class B and Class C shares, respectively. These voluntary limitations may be
modified or terminated at any time without notice. The Distributor also receives
CDSC's from certain redeeming shareholders. See "Shareholder Guide--How to Sell
Your Shares--Contingent Deferred Sales Charges."
    
 
   
  For the fiscal year ended August 31, 1998, the Series paid distribution
expenses of .10 of 1%, .50 of 1% and .74 of 1% of the average daily net assets
of the Class A, Class B and Class C shares, respectively. The Series 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 Class A, Class B and Class C
shares of the Series will be allocated to each such class based upon the ratio
of sales of each such class to the sales of Class A, Class B or Class C shares
of the Series other than expenses allocable to a particular class. The
distribution fee and sales charge of one class will not be used to subsidize the
sale of another class.
    
 
   
  Each Plan provides that it shall continue in effect from year to year provided
that a majority of the Trustees of the Fund, including a majority of the
Trustees 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
Trustees), vote annually to continue the Plan. Each Plan may be terminated with
respect to the Series at any time by vote of a majority of the Rule 12b-1
Trustees or of a majority of the outstanding shares of the applicable class of
the Series. The Series will not be obligated to pay distribution and service
fees incurred under any Plan if it is terminated or not continued.
    
 
   
  In addition to distribution and service fees paid by the Series 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 and other persons which
distribute shares of the Series. Such payments may be calculated by reference to
the NAV of shares sold by such persons or otherwise.
    
 
                                       16

CUSTODIAN AND TRANSFER AND DIVIDEND DISBURSING AGENT
 
  State Street Bank and Trust Company, One Heritage Drive, North Quincy,
Massachusetts 02171, serves as Custodian for the portfolio securities of the
Series and cash and, in that capacity, maintains certain financial and
accounting books and records pursuant to an agreement with the Fund. Its mailing
address is P. O. Box 1713, Boston, Massachusetts 02105.
 
   
  Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), Raritan
Plaza One, Edison, New Jersey 08837, serves as Transfer Agent and Dividend
Disbursing Agent and, in those capacities, maintains certain books and records
for the Fund. PMFS is a wholly-owned subsidiary of PIFM. Its mailing address is
P. O. Box 15005, New Brunswick, New Jersey 08906-5005.
    
 
   
YEAR 2000
    
 
   
  The services provided to the Fund and the shareholders by the Manager, the
Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of outside service providers.
Many computer software systems in use today cannot distinguish the year 2000
from the year 1900 because of the way dates are encoded and calculated. Such
event could have a negative impact on handling securities trades, payments of
interest and dividends, pricing and account services. Although, at this time,
there can be no assurance that there will be no adverse impact on the Fund, the
Manager, the Distributor, the Transfer Agent and the Custodian have advised the
Fund that they have been actively working on necessary changes to their computer
systems to prepare for the year 2000 and expect that their systems, and those of
outside service providers, will be adapted in time for the event.
    
 
   
  Additionally, issuers of securities generally as well as those purchased by
the Fund may confront year 2000 compliance issues which, if material and not
resolved, could have an adverse impact on securities markets and/or a specific
issuer's performance and result in a decline in the value of securities held by
the Fund.
    
 
                         HOW THE FUND VALUES ITS SHARES
 
   
  THE SERIES' NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING ITS
LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE REMAINDER BY THE
NUMBER OF OUTSTANDING SHARES. NAV IS CALCULATED SEPARATELY FOR EACH CLASS. THE
TRUSTEES HAVE FIXED THE SPECIFIC TIME OF DAY FOR THE COMPUTATION OF THE NAV OF
THE SERIES 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 Trustees. Securities may also be valued based on values
provided by a pricing service. See "Net Asset Value" in the Statement of
Additional Information.
 
  The Series 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 Series or days on which changes in
the value of the Series' portfolio securities do not materially affect the NAV.

  Although the legal rights of each class of shares are substantially identical,
the different expenses borne by each class will result in different NAV's 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 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 THE YIELD, TAX EQUIVALENT YIELD AND
AVERAGE ANNUAL TOTAL RETURN AND AGGREGATE TOTAL RETURN OF THE SERIES 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
Series over a one-month or 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 Series. The total
return shows how much an investment in the Series would have increased
(decreased) over a specified period of time (I.E., one, five or ten years or
since inception of the Series) assuming that all distributions and dividends by
the Series 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 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 shares of
the Series. 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 Series' 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 SERIES HAS QUALIFIED AND INTENDS TO REMAIN QUALIFIED AS A REGULATED
INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, THE SERIES WILL
NOT BE SUBJECT TO FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME AND NET
CAPITAL GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS. TO THE EXTENT
NOT DISTRIBUTED BY THE SERIES, NET TAXABLE INVESTMENT INCOME AND CAPITAL GAINS
AND LOSSES ARE TAXABLE TO THE SERIES. See "Taxes, Dividends and Distributions"
in the Statement of Additional Information.
    
 
   
  To the extent the Series invests in taxable obligations, it will earn taxable
investment income. Also, to the extent the Series sells securities or engages in
hedging transactions in futures contracts and options thereon, it may earn both
capital gain or loss. Capital gain or loss may also arise upon the sale of
municipal securities, as well as taxable obligations. Under the Internal Revenue
Code, special rules apply to the treatment of certain options and futures
contracts (Section 1256 contracts). At the end of each year, such investments
held by the Series will be required to be marked to market for federal income
tax purposes; that is,
    
 
                                       18
<PAGE>
   
treated as having been sold at market value. Sixty percent of any gain or loss
recognized on these deemed sales and on actual dispositions will be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss. See "Taxes, Dividends and Distributions" in the Statement
of Additional Information.
    
 
   
  Gain or loss realized by the Series 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 taxable ordinary
income to the extent of any market discount. Market discount generally is the
difference, if any, between the price paid by the Series 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 issue price of the security). The market
discount rule does not apply to any security that was acquired by the Series at
its original issue.
    
 
TAXATION OF SHAREHOLDERS
 
  In general, the character of tax-exempt interest distributed by the Series
will flow through as tax-exempt interest to its shareholders provided that 50%
or more of the value of its assets at the end of each quarter of its taxable
year is invested in state, municipal and other obligations, the interest on
which is excluded from gross income for federal income tax purposes. During
normal market conditions, at least 80% of the Series' total assets will be
invested in such obligations. See "How the Fund Invests--Investment Objective
and Policies."
 
   
  Any dividends out of net taxable investment income, together with
distributions of net short-term gains (I.E., the excess of net short-term
capital gains over net long-term capital losses) distributed to shareholders,
will be taxable as ordinary income to the shareholder whether or not reinvested.
Any net capital gains (I.E., the excess of net capital gains from the sale of
assets held for more than 12 months over net short-term capital losses)
distributed to shareholders will be taxable as capital gains to the
shareholders, whether or not reinvested and regardless of the length of time a
shareholder has owned his or her shares. Recent legislation created various
categories of capital gains applicable to individuals. For capital gains
recognized upon the sale of assets by this series after December 31, 1997, the
maximum long-term capital gains tax rate for individuals is 20%. The maximum
capital gains tax rate for corporate shareholders currently is the same as the
maximum tax rate for ordinary income.
    
 
   
  Any gain or loss realized upon a sale or redemption of Series shares by a
shareholder who is not a dealer in securities will be treated as capital gain or
loss. Any such capital gain or loss will be treated as long-term capital gain or
loss if the shares were held for more than 12 months. In the case of an
individual, any such long-term capital gain will be taxable at the maximum rate
of 20%. The maximum capital gain tax rate for a corporation is the same as that
for ordinary income. Any 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. In addition, any
short-term capital loss will be disallowed to the extent of any tax-exempt
dividends received by the shareholder on shares that are held for six months or
less.
    
 
  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 Class
B or Class C shares for Class A shares constitutes a taxable event for federal
income tax purposes. However, such opinions are not binding on the Internal
Revenue Service.
 
  CERTAIN INVESTORS MAY INCUR FEDERAL ALTERNATIVE MINIMUM TAX LIABILITY AS A
RESULT OF THEIR INVESTMENT IN THE FUND. Tax-exempt interest from certain
municipal obligations (I.E., certain private activity bonds issued after August
7, 1986) will be treated as an item of tax preference for purposes of the
alternative minimum tax. The Fund anticipates that, under regulations to be
promulgated, items of tax preference incurred by the Series will be attributed
to the Series' shareholders, although some portion of such items could be
allocated to the Series itself. Depending upon each shareholder's individual
circumstances, the attribution of items of tax preference incurred by the Series
could result in liability for the shareholder for the alternative minimum tax.
Similarly, the Series could be liable for the alternative minimum tax for items
of tax preference attributed to it. The Series is permitted to invest in
municipal obligations of the type that will produce items of tax preference.
 
                                       19
<PAGE>
   
  Distributions relating to interest on all municipal obligations will be
included in a corporate shareholder's current earnings for purposes of the
adjustment for current earnings for alternative minimum tax purposes. Corporate
shareholders should consult with
their tax advisers with respect to this potential adjustment.
    
 
  Under Michigan law, dividends paid by the Series that are derived from
interest payments attributable to Michigan Obligations are exempt from Michigan
income tax and any income taxes imposed by cities in Michigan for individuals
who reside in Michigan and from the Michigan single business tax for
corporations that are subject to such tax to the extent such dividends are
exempt from federal income tax (except for possible application of the
alternative minimum tax). An investment in the Series, to the extent
attributable to interest on Michigan Obligations, will also be excluded from the
Michigan intangibles tax.
 
   
  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 Series is required to withhold and remit
to the U.S. Treasury 31% of redemption proceeds on the accounts of certain
shareholders who fail to furnish their tax identification numbers on IRS Form
W-9 (or IRS Form W-8 in the case of certain foreign shareholders) with the
required certifications regarding the shareholder's status under the federal
income tax law. Such withholding is also required on taxable dividends and
capital gain distributions made by the Series unless it is reasonably expected
that at least 95% of the distributions of the Series are comprised of tax-exempt
dividends.
 
  Dividends of net taxable investment income and distributions of net short-term
capital gains paid to a shareholder (including a shareholder acting as a nominee
or fiduciary) who is a nonresident alien individual, a foreign corporation or a
foreign partnership (foreign shareholder) are subject to a 30% (or lower treaty
rate) withholding tax upon the gross amount of the dividends unless the
dividends are effectively connected with a U.S. trade or business conducted by
the foreign shareholder. Capital gain dividends paid to a foreign shareholder
are generally not subject to withholding tax. A foreign shareholder will,
however, be required to pay U.S. income tax on any dividends and capital gain
distributions which are effectively connected with a U.S. trade or business of
the foreign shareholder.
 
DIVIDENDS AND DISTRIBUTIONS
 
  THE SERIES EXPECTS TO DECLARE DAILY AND PAY MONTHLY DIVIDENDS OF NET
INVESTMENT INCOME, IF ANY, AND MAKE DISTRIBUTIONS AT LEAST ANNUALLY OF ANY
CAPITAL GAINS IN EXCESS OF CAPITAL LOSSES. Dividends paid by the Series 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 charges,
generally resulting in lower dividends for Class B and Class C 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 SHARES OF THE SERIES
BASED ON THE NAV OF EACH CLASS OF THE SERIES ON THE PAYMENT DATE AND RECORD
DATE, RESPECTIVELY, OR SUCH OTHER DATE AS THE TRUSTEES 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 of both the
dollar amount and the taxable status of that year's dividends and distributions
on a per share basis.
    
 
   
  IF YOU BUY SHARES ON OR IMMEDIATELY BEFORE THE RECORD DATE (THE DATE THAT
DETERMINES WHO RECEIVES THE DIVIDEND), YOU WILL RECEIVE A PORTION OF THE MONEY
YOU INVESTED AS A TAXABLE DIVIDEND. THEREFORE, YOU SHOULD CONSIDER THE TIMING OF
DIVIDENDS WHEN BUYING SHARES OF THE FUND.

                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
 
  THE FUND WAS ESTABLISHED AS A MASSACHUSETTS BUSINESS TRUST ON MAY 18, 1984, BY
A DECLARATION OF TRUST. The Fund's activities are supervised by its Trustees.
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares in separate series, currently designated as the
Connecticut Money Market Series, Florida Series, Maryland Series, Massachusetts
Series, Massachusetts Money Market Series, Michigan Series, New Jersey Series,
New Jersey Money Market Series, New York Series, New York Money Market Series,
North Carolina Series, Ohio Series and Pennsylvania Series. The Series is
authorized to issue an unlimited number of shares, divided into three classes,
designated Class A, Class B and Class C. Each class of shares represents an
interest in the same assets of the Series and are identical in all respects
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 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, (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." In accordance with the Fund's Declaration of Trust, the
Trustees may authorize the creation of additional series and classes within such
series, with such preferences, privileges, limitations and voting and dividend
rights as the Trustees may determine.
 
  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
the Series is equal as to earnings, assets and voting privileges, except as
noted above, and each class 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 beneficial interest of each series 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 Trustees.
 
  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 TRUSTEES IS REQUIRED TO BE
ACTED UPON 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 TRUSTEES OR TO TRANSACT ANY OTHER BUSINESS.
 
  The Declaration of Trust and the By-Laws of the Fund are designed to make the
Fund similar in certain respects to a Massachusetts business corporation. The
principal distinction between a Massachusetts business corporation and a
Massachusetts business trust relates to shareholder liability. Under
Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
fund, which is not the case with a corporation. The Declaration of Trust of the
Fund provides that shareholders shall not be subject to any personal liability
for the acts or obligations of the Fund and that every written obligation,
contract, instrument or undertaking made by the Fund shall contain a provision
to the effect that the shareholders are not individually bound thereunder.

  This Prospectus, including the Statement of Additional Information which has
been incorporated by reference herein, does not contain all the information set
forth in the Registration Statement filed by the Fund with the Commission under
the Securities Act. Copies of the Registration Statement may be obtained at a

                               SHAREHOLDER GUIDE
 
HOW TO BUY SHARES OF THE FUND
 
   
  The Trustees of the Fund have recently approved a proposal to exchange the
assets and liabilities of the Series of the Fund for shares of Prudential
National Municipals Fund, Inc. (National Municipals Fund). Class A, Class B and
Class C shares of the Series would be exchanged at relative net asset value for
Class A shares of National Municipals Fund, the investment objective of which is
to seek a high level of current income exempt from federal income taxes. The
transfer has been approved by the Trustees of the Fund and by the Board of
Directors of National Municipals Fund and is subject to approval by the
shareholders of the Series. It is anticipated that a proxy statement/prospectus
relating to the transaction will be mailed to the Series' shareholders in late
October 1998.
    
 
   
  Under the terms of the proposal, shareholders of the Series would become
shareholders of National Municipals Fund. No sales charge would be imposed on
the proposed transfer. The Fund anticipates obtaining an opinion of its counsel
that the transaction would be a tax-free reorganization under the Internal
Revenue Code and therefore no gain or loss for Federal income tax purposes would
be recognized by shareholders of the Series.
    
 
   
  EFFECTIVE IMMEDIATELY, THE FUND WILL NO LONGER ACCEPT ORDERS TO PURCHASE OR
EXCHANGE FOR SHARES OF THE SERIES, EXCEPT FOR PURCHASES BY CERTAIN RETIREMENT
AND EMPLOYEE PLANS (EXCLUDING IRA ACCOUNTS). Existing shareholders may continue
to acquire shares through dividend reinvestment. The current redemption
privilege and the current exchange privilege of obtaining shares of other
Prudential Mutual Funds will remain in effect until the transaction is
consummated. If the transaction is not consummated, the Fund will resume
accepting orders to purchase or exchange for shares of the Series. See "How to
Sell Your Shares" and "How to Exchange Your Shares" below.
    
 
   
  IF THE FUND RESUMES ACCEPTING ORDERS TO PURCHASE SHARES OF THE SERIES, YOU MAY
PURCHASE SHARES OF THE SERIES THROUGH THE DISTRIBUTOR, THROUGH DEALERS,
INCLUDING PRUDENTIAL SECURITIES OR PRUSEC, OR DIRECTLY FROM THE FUND THROUGH ITS
TRANSFER AGENT, PRUDENTIAL MUTUAL FUND SERVICES LLC (PMFS OR THE TRANSFER
AGENT), ATTENTION: INVESTMENT SERVICES, P.O. BOX 15020, NEW BRUNSWICK, NEW
JERSEY 08906-5020. The purchase price is the NAV next determined following
receipt of an order in proper form (in accordance with procedures established by
the Transfer Agent in connection with investors' accounts) by the Distributor,
your Dealer or the Transfer Agent plus a sales charge which, at your option, may
be imposed either at the time of purchase, on a deferred basis, or both. Class A
shares are sold with a front-end sales charge. Class B shares are subject to a
CDSC. Class C shares are sold with a low front-end sales charge, but are also
subject to a CDSC. Payments may be made by wire, check or through your brokerage
account. See "Alternative Purchase Plan" below and "How the Fund Values its
Shares."
    
 
  An investment in the Series may not be appropriate for tax-exempt or
tax-deferred investors. Such investors should consult their own tax advisers.
 
   
  The minimum initial investment is $1,000 for Class A and Class B shares and
$2,500 for Class C shares. The minimum subsequent investment is $100 for all
classes. All minimum investment requirements are waived for certain employee
savings plans. For purchases made through the Automatic Investment Plan, the
minimum initial and subsequent investment is $50. See "Shareholder Services"
below.
    
 
  The Fund reserves the right to reject any purchase order (including an
exchange into the Series) or to suspend or modify the continuous offering of its
shares. See "How to Sell Your Shares" below.
 
   
  Application forms can be obtained from the Transfer Agent, your Dealer or the
Distributor. If a share certificate is desired, it must be requested in writing
for each transaction. Certificates are issued only for full shares. Shareholders
who hold their shares through Prudential Securities will not receive share
certificates.
    
 
                                       22
<PAGE>
   
  Your Dealer is responsible for forwarding payment promptly to the Fund. The
Distributor reserves the right to cancel any purchase order for which payment
has not been received by the third business day following the placement of the
order.
    
 
   
  Dealers may charge their customers a separate fee for processing purchases and
redemptions. In addition, transactions in shares of the Series may be subject to
postage and handling charges imposed by your Dealer. Any such charge is retained
by the Dealer and is not remitted to the Fund.
    
 
  PURCHASE BY WIRE. For an initial purchase of shares of the Series by wire, you
must first telephone PMFS at (800) 225-1852 (toll-free) to receive an account
number. The following information will be requested: your name, address, tax
identification number, class election, dividend distribution election, amount
being wired and wiring bank. Instructions should then be given by you to your
bank to transfer funds by wire to State Street Bank and Trust Company (State
Street), Boston, Massachusetts, Custody and Shareholder Services Division,
Attention: Prudential Municipal Series Fund (Michigan Series), specifying on the
wire the account number assigned by PMFS and your name and identifying the class
in which you are eligible to invest (Class A, Class B or Class C shares) and the
name of the Series.
 
   
  If you arrange for receipt by State Street of federal funds prior to the
calculation of NAV (4:15 P.M., New York time), on a business day, you may
purchase shares of the Series as of that day. See "Net Asset Value" in the
Statement of Additional Information.
    
 
   
  In making a subsequent purchase order by wire, you should wire State Street
directly and should be sure that the wire specifies Prudential Municipal Series
Fund, (Michigan Series), 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.
    
 
ALTERNATIVE PURCHASE PLAN
 
   
  THE FUND OFFERS THROUGH THIS PROSPECTUS THREE CLASSES OF SHARES (CLASS A,
CLASS B AND CLASS C SHARES) WHICH ALLOWS YOU TO CHOOSE THE MOST BENEFICIAL SALES
CHARGE STRUCTURE FOR YOUR INDIVIDUAL CIRCUMSTANCES, GIVEN THE AMOUNT OF THE
PURCHASE, THE LENGTH OF TIME YOU EXPECT TO HOLD THE SHARES AND OTHER RELEVANT
CIRCUMSTANCES (ALTERNATIVE PURCHASE PLAN).

  The three classes of shares represent an interest in the same portfolio of
investments of the Series 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 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

<PAGE>
   
other class, (iii) each class has a different exchange privilege, 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 the Class A shares.
    
 
   
  Dealers, financial advisers and other sales agents who sell shares of the
Series 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 Series:
    
 
   
  If you intend to hold your investment in a Fund for less than 3 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 3 years, but less than 4
years, or for more than 5 years, but less than 6 years, you should consider
purchasing Class A shares, because the maximum 3% initial sales charge plus the
cumulative annual distribution-related fee on Class A would be lower than: (i)
the CDSC plus the cumulative annual distribution-related fee on Class B shares;
and (ii) the 1% initial sales charge plus the cumulative annual
distribution-related fee on Class C shares.
    
 
   
  If you intend to hold your investment for more than 4 years, but less than 5
years, you may consider purchasing Class A or Class B shares because: (i) the
maximum 3% initial sales charge plus the cumulative annual distribution-related
fee on Class A shares and (ii) the CDSC plus the cumulative annual
distribution-related fee on Class B shares would be lower than 1% initial sales
charge plus the cumulative annual distribution-related fee on Class C shares.
    
 
   
  If you intend to hold your investment for more than 6 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 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 3
years for the 1% initial sales charge plus the higher cumulative annual
distribution-related fee on the 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 NAV, the effect of the return on the investment over this period
of time or redemptions when the CDSC is applicable.

  The Distributor may reallow the entire initial sales charge to Dealers.
Dealers may be deemed to be underwriters, as that term is defined under federal
securities laws. The Distributor reserves the right, without prior notice to any
Dealer, to suspend or eliminate Dealer concessions or commissions.
    
 
   
  In connection with the sale of Class A shares at NAV (without payment of an
initial sales charge), the Manager, the Distributor or one of their affiliates
may pay Dealers, financial advisers and other persons which distribute shares a
finders' fee from their own resources based on a percentage of the NAV of shares
sold by such persons.
    
 
  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 the Distributor
or the Transfer Agent, by the following persons: (a) officers of the Prudential
Mutual Funds (including the Fund), (b) employees of the Distributor, Prudential
Securities, PIFM and their subsidiaries and members of the families of such
persons who maintain an employee related account at Prudential Securities or the
Transfer Agent, (c) employees of subadvisers of the Prudential Mutual Funds
provided that the purchases at NAV are permitted by such person's employer, (d)
Prudential, employees and special agents of Prudential and its subsidiaries and
all persons who have retired directly from active service with Prudential or one
of its subsidiaries, (e) registered representatives and employees of Dealers who
have entered into a selected dealer agreement with the Distributor, 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.
    
 
   
  For an investor to obtain any reduction or waiver of the initial sales
charges, at the time of the sale either the Transfer Agent must be notified
directly by the investor or the Distributor must be notified by the Dealer
facilitating the transaction that the sale qualifies for the reduced or waived
sales charge. The reduction or waiver will be granted subject to confirmation of
your
    
 
                                       25
<PAGE>
entitlement. No initial sales charges are imposed upon Class A shares acquired
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 shares is the NAV next determined following
receipt of an order in proper form by the Transfer Agent, your Dealer or the
Distributor. The offering price of Class C shares is the NAV next determined
following receipt of an order in proper form by the Transfer Agent, your Dealer
or the Distributor plus a sales charge equal to 1% of the public offering price.
Redemption 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, from its own resources, sales commissions of up to
4% of the purchase price of Class B shares to Dealers, financial advisers and
other persons who sell Class B shares at the time of sale. This facilitates the
ability of the Trust to sell the Class B shares of the Funds without an initial
sales charge being deducted at the time of purchase. The Distributor anticipates
that it will recoup its advancement of sales commissions from the combination of
the CDSC and the distribution fee. In connection with the sale of Class C
shares, the Distributor will pay, partially from its own resources, Dealers,
financial advisers and other persons which distribute Class C shares a sales
commission of up to 2% of the purchase price at the time of the sale. The
Distributor anticipates that it would recoup its advancement of sales
commissions from the combination of the CDSC and the distribution fee. See "How
the Fund is Managed--Distributor."
    
 
   
  WAIVER OF INITIAL SALES CHARGE--CLASS C SHARES
    
 
   
  INVESTMENTS OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. Investors
may purchase Class C shares at NAV, without the initial sales charge, with the
proceeds from the redemption of shares of any unaffiliated registered investment
company which were not held through an account with any Prudential affiliate.
Such purchases must be made within 60 days of the redemption. Investors eligible
for this waiver include: (i) investors purchasing shares through an account at
Prudential Securities Incorporated; (ii) investors purchasing shares through an
ADVANTAGE Account or an Investor Account with Pruco Securities Corporation; and
(iii) investors purchasing shares through other Dealers. This waiver is not
available to investors who purchase shares directly from the Transfer Agent. You
must notify the Transfer Agent directly or through your Dealer if you are
entitled to this waiver and provide the Transfer Agent with such supporting
documents as it may deem appropriate.
    
 
HOW TO SELL YOUR SHARES
 
   
  YOU CAN REDEEM YOUR SHARES OF THE SERIES AT ANY TIME FOR CASH AT THE NAV NEXT
DETERMINED AFTER THE REDEMPTION REQUEST IS RECEIVED IN PROPER FORM (IN
ACCORDANCE WITH PROCEDURES ESTABLISHED BY THE TRANSFER AGENT IN CONNECTION WITH
INVESTORS' ACCOUNTS) BY THE DISTRIBUTOR, YOUR DEALER OR THE TRANSFER AGENT. SEE
"HOW THE FUND VALUES ITS SHARES." In certain cases, however, redemption proceeds
will be reduced by the amount of any applicable CDSC, as described below. See
"Contingent Deferred Sales Charges" below. If you are redeeming your shares
through a Dealer, your Dealer must receive your sell order before the Fund
computes its NAV for that day (I.E., 4:15 p.m., New York time) in order to
receive that day's NAV. Your Dealer will be responsible for furnishing all
necessary documentation to the Distributor and may charge you for its services
in connection with redeeming shares of the Fund.
    
 
   
  IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A WRITTEN REQUEST FOR REDEMPTION
SIGNED BY YOU EXACTLY AS THE ACCOUNT IS REGISTERED IS REQUIRED. IF YOU HOLD
CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE FACE OF THE
CERTIFICATES, MUST BE RECEIVED BY THE TRANSFER AGENT, THE DISTRIBUTOR OR YOUR
DEALER IN ORDER FOR THE REDEMPTION REQUEST TO BE PROCESSED. IF REDEMPTION IS
REQUESTED BY A CORPORATION, PARTNERSHIP, TRUST OR FIDUCIARY, WRITTEN EVIDENCE
    
 
                                       26
<PAGE>
   
OF AUTHORITY ACCEPTABLE TO THE TRANSFER AGENT MUST BE SUBMITTED BEFORE SUCH
REQUEST WILL BE ACCEPTED. All correspondence and documents concerning
redemptions should be sent to the Fund in care of its Transfer Agent, Prudential
Mutual Fund Services LLC, Attention: Redemption Services, P.O. Box 15010, New
Brunswick, New Jersey 08906-5010, the Distributor or your Dealer.
    
 
   
  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.
    
 
   
  PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE MADE BY CHECK WITHIN SEVEN
DAYS AFTER RECEIPT BY THE TRANSFER AGENT, THE DISTRIBUTOR OR YOUR DEALER OF THE
CERTIFICATE AND/OR WRITTEN REQUEST EXCEPT AS INDICATED BELOW. IF YOU HOLD SHARES
THROUGH A DEALER, PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE CREDITED
TO YOUR ACCOUNT AT YOUR DEALER 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 Series of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Series fairly
to determine the value of its net assets, or (d) during any other period when
the Commission, by order, so permits; provided that applicable rules and
regulations of the Commission shall govern as to whether the conditions
prescribed in (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, WHICH MAY TAKE 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 CASHIER'S CHECK.
    
 
   
  REDEMPTION IN KIND. If the Trustees determine that it would be detrimental to
the best interests of the remaining shareholders of the Fund to make payment
wholly or partly in cash, the Fund may pay the redemption price in whole or in
part by a distribution in kind of securities from the investment portfolio of
the Series of the Fund, in lieu of cash, in conformity with applicable rules of
the Commission. Securities will be readily marketable and will be valued in the
same manner as in a regular redemption. See "How the Fund Values its Shares." If
your shares are redeemed in kind, you will incur transaction costs in converting
the assets into cash. The Fund, however, has elected to be governed by Rule
18f-1 under the Investment Company Act, under which the Fund is obligated to
redeem shares solely in cash up to the lesser of $250,000 or 1% of the NAV of
the Fund during any 90-day period for any one shareholder.
    
 
   
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Trustees
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 NAV of less
than $500 due to a redemption. The Fund will give such shareholders 60 days'
prior written notice in which to purchase sufficient additional shares to avoid
such redemption. No CDSC will be imposed on any such involuntary redemption.
    
 
   
  90-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not previously
exercised the repurchase privilege, you may reinvest any portion or all of the
proceeds of such redemption in shares of the Series at the NAV next determined
after the order is received, which must be within 90 days after the date of the
redemption. Any CDSC paid in connection with such redemption will be credited
(in shares) to your account. (If less than a full repurchase is made, the credit
will be on a PRO RATA basis.) You must notify the Transfer Agent, either
directly or through the Distributor or your Dealer, 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 may affect the federal tax treatment of any gain
realized upon redemption.

<PAGE>
  CONTINGENT DEFERRED SALES CHARGES
 
   
  Redemptions of Class B shares will be subject to a CDSC declining from 5% to
zero over a six-year period. Class C shares redeemed within 18 months 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 18 months, 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 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. 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 NAV above the total amount of payments for
the purchase of Series shares made during the preceding six years (five years
for Class B shares purchased prior to January 22, 1990); then of amounts
representing the cost of shares held beyond the applicable CDSC period; and
finally, of amounts representing the cost of shares held for the longest period
of time within the applicable CDSC period.
    
 
  For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided to
redeem $500 of your investment. Assuming at the time of the redemption the NAV
had appreciated to $12 per share, the value of your Class B shares would be
$1,260 (105 shares at $12 per share). The CDSC would not be applied to the value
of the reinvested dividend shares and the amount which represents appreciation
($260). Therefore, $240 of the $500 redemption proceeds ($500 minus $260) would
be charged at a rate of 4% (the applicable rate in the second year after
purchase) for a total CDSC of $9.60.
 
  For federal income tax purposes, the amount of the CDSC will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the
redemption of shares.
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES. The CDSC will be
waived in the case of a redemption following the death or disability of a
shareholder or, in the case of a trust account, following the death or
disability of the grantor.
    
 
                                       28
<PAGE>
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 Trustee of the Fund.
 
   
  SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on certain
redemptions from a Systematic Withdrawal Plan. On an annual basis, up to 12% of
the total dollar amount subject to the CDSC may be redeemed without charge. The
Transfer Agent will calculate the total amount available for this waiver
annually on the anniversary date of your purchase or, for shares purchased prior
to March 1, 1997, on March 1 of the current year. The CDSC will be waived (or
reduced) on redemptions until this threshold 12% amount is reached.
    
 
   
  You must notify the Transfer Agent either directly or through your Dealer, at
the time of redemption, that you are entitled to waiver of the CDSC 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.
    
 
  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 NAV without the imposition of any additional sales charge.
    
 
  Since the Fund tracks amounts paid rather than the number of shares bought on
each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will be
determined on each conversion date in accordance with the following formula: (i)
the ratio of (a) the amounts paid for Class B shares purchased at least seven
years prior to the conversion date to (b) the total amount paid for all Class B
shares purchased and then held in your account (ii) multiplied by the total
number of Class B shares purchased and then held in your account. Each time any
Eligible Shares in your account convert to Class A shares, all shares or amounts
representing Class B shares then in your account that were acquired through the
automatic reinvestment of dividends and other distributions will convert to
Class A shares.
 
   
  For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different NAV's, 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 NAV of the Class A shares may be higher than that of the Class B
shares at the time of conversion. Thus, although the aggregate dollar value will
be the same, you may receive fewer Class A shares than Class B shares converted.
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
 
                                       29
<PAGE>
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 and Class C 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 Series 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 SERIES, YOU HAVE AN EXCHANGE PRIVILEGE WITH THE OTHER
SERIES OF THE FUND AND 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 OF THE SERIES
MAY BE EXCHANGED FOR CLASS A, CLASS B AND CLASS C SHARES, RESPECTIVELY, OF THE
OTHER SERIES OF THE FUND OR ANOTHER FUND ON THE BASIS OF THE RELATIVE NAV. No
sales charge will be imposed at the time of 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, Inc. 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, weekdays, except
holidays, between the hours of 8:00 A.M. and 6:00 P.M., New York time. For your
protection and to prevent fraudulent exchanges, your telephone call will be
recorded and you will be asked to provide your personal identification number. A
written confirmation of the exchange transaction will be sent to you. NEITHER
THE FUND NOR ITS AGENTS WILL BE LIABLE FOR ANY LOSS, LIABILITY OR COST WHICH
RESULTS FROM ACTING UPON INSTRUCTIONS REASONABLY BELIEVED TO BE GENUINE UNDER
THE FOREGOING PROCEDURES. All exchanges will be made on the basis of the
relative NAV of the two funds (or series) next determined after the request is
received in good order.
    
 
  IF YOU HOLD SHARES THROUGH PRUDENTIAL SECURITIES, YOU MUST EXCHANGE YOUR
SHARES BY CONTACTING YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISER.
 
  IF YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE
FACE OF THE CERTIFICATES, MUST BE RETURNED IN ORDER FOR THE SHARES TO BE
EXCHANGED. 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 PRIVILEGE. 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"
above). Under this exchange privilege, amounts representing any Class B and
Class C shares (which are not subject to a CDSC) held in such a
 
                                       30
<PAGE>
   
shareholder's account will be automatically exchanged for Class A shares 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 NAV above the total
amount of payments for the purchase of Class B or Class C shares and (3) amounts
representing Class B or Class C shares held beyond the applicable CDSC period.
Class B and Class C shareholders must notify the Transfer Agent either directly
or through their Dealer or the Distributor that they are eligible for this
special exchange privilege.
    
 
   
  The exchange privilege is not a right and may be suspended, terminated or
modified on 60 days' notice to shareholders.
    
 
   
  FREQUENT TRADING. The Fund and the other Prudential Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market timing
investment strategies and excessive trading can have on efficient portfolio
management, each Prudential Mutual Fund, including the Fund, reserves the right
to refuse purchase orders and exchanges by any person, group or commonly
controlled accounts, if, in the Manager's sole judgment, such person, group or
accounts were following a market timing strategy or were otherwise engaging in
excessive trading (Market Timers).
    
 
  To implement this authority to protect the Fund and its shareholders from
excessive trading, the Fund will reject all exchanges and purchases from a
Market Timer unless the Market Timer has entered into a written agreement with
the Fund or its affiliates pursuant to which the Market Timer has agreed to
abide by certain procedures, which include a daily dollar limit on trading. The
Fund may notify the Market Timer of rejection of an exchange or purchase order
subsequent to the day on which the order was placed.
 
SHAREHOLDER SERVICES
 
   
  In addition to the exchange privilege, as a shareholder in the Series, you can
take advantage of the following 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 Series 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
your Dealer, you should contact your Dealer.
    
 
   
  - AUTOMATIC INVESTMENT PLAN (AIP). Under AIP you may make regular purchases of
the Series' shares in amounts as little as $50 via an automatic debit to a bank
account or brokerage account (including a Command Account). For additional
information about this service, you may contact the Distributor, your Dealer 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" above.
 
   
  - THE PRUTECTOR PROGRAM-OPTIONAL GROUP TERM LIFE INSURANCE. Prudential makes
available optional group term life insurance coverage to purchasers of shares of
certain Prudential Mutual Funds which are held in an eligible brokerage account.
This insurance protects the value of your mutual fund investment for your
beneficiaries against market downturns. The insurance benefit is based on the
difference at the time of the insured's death between the protected value and
the then current market value of the shares. This coverage is not available in
all states and is subject to various restrictions and limitations. For more
complete information about this program, including charges and expenses, please
contact your Prudential representative.
    
 
  - 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
 
                                       31
<PAGE>
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, 100 Mulberry Street,
Newark, New Jersey 07102-4077. In addition, monthly unaudited financial data is

                        DESCRIPTION OF SECURITY RATINGS
 
MOODY'S INVESTORS SERVICE
 
BOND RATINGS
 
  Aaa:  Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
   
  Aa:  Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group, they comprise what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than the Aaa securities.
    
 
  A:  Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium-grade obligations. Factors giving security
to principal and interest are considered adequate but elements may be present
which suggest a susceptibility to impairment sometime in the future.
 
   
  Baa:  Bonds which are rated Baa are considered as medium grade obligations,
(I.E., 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.
    
 
  Ba:  Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
   
  B:  Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
    
 
  Caa:  Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
  Ca:  Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.
 
  C:  Bonds which are rated C are the lowest-rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.
 
SHORT-TERM RATINGS
 
  Moody's ratings for tax-exempt notes and other short-term loans are designated
Moody's Investment Grade (MIG). This distinction is in recognition of the
differences between short-term and long-term credit risk.
 
  MIG 1:  Loans bearing the designation MIG 1 are of the best quality, enjoying
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.
 
  MIG 2:  Loans bearing the designation MIG 2 are of high quality, with margins
of protection ample although not so large as in the preceding group.
 
                                      A-1
<PAGE>
  MIG 3:  Loans bearing the designation MIG 3 are of favorable quality, with all
security elements accounted for but lacking the strength of the preceding
grades.
 
  MIG 4:  Loans bearing the designation MIG 4 are of adequate quality.
Protection commonly regarded and required of an investment security is present
and although not distinctly or predominantly speculative, there is specific
risk.
 
   
  SG:  This designation denotes speculative quality. Debt instruments in this
category lack margins of protection.
    
 
   
SHORT-TERM DEBT RATINGS
    
 
   
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted.
    
 
   
  PRIME-1: Issuers rated "Prime-1" (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
    
 
   
  - Leading market positions in well-established industries.
    
 
   
  - High rates of return on funds employed.
    
 
   
  - Conservative capitalization structure with moderate reliance on debt and
  ample asset protection.
    
 
   
  - Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
    
 
   
  - Well-established access to a range of financial markets and assured
  sources of alternate liquidity.
    
 
   
  PRIME-2: Issuers rated "Prime-2" (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This normally will
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
    
 
  PRIME-3:  Issuers rated Prime-3 (or supporting institutions) have an
acceptable ability for repayment of senior short-term debt obligations.
 
  NOT PRIME:  Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
   
STANDARD & POOR'S RATINGS GROUP
    
 
   
DEBT RATINGS
    
 
   
  AAA: An obligation rated AAA has the highest rating assigned by S&P. The
obligor's capacity to meet its financial commitment on the obligation is
extremely strong.
    
 
   
  AA: An obligation rated AA differs from the highest rated obligations only in
small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.
    
 
   
  A: An obligation rated A is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.
    
 
   
  BBB: An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.
    
 
   
  BB, B, CCC, CC AND C: Obligations rated BB, B, CCC, CC and C are regarded as
having significant speculative characteristics. BB indicates the least degree of
speculation and C the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.
    
 
                                      A-2
<PAGE>
  D:  Debt rated D is in payment default. This rating is used when interest
payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period.
 
COMMERCIAL PAPER RATINGS
 
  An S&P Commercial Paper rating is a current assessment of the likelihood of
timely payment of debt considered short-term in the relevant market.
 
   
  A-1:  This designation indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus sign (+) designation.
    
 
   
  A-2:  Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.
    
 
  A-3:  Issues carrying this designation have adequate capacity for timely
payment. They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.
 
MUNICIPAL NOTES
 
  A municipal note rating reflects the liquidity concerns and market access
risks unique to municipal notes. Municipal notes due in three years or less will
likely receive a municipal note rating, while notes maturing beyond three years
will most likely receive a long-term debt rating. Municipal notes are rated
SP-1, SP-2 or SP-3. The designation SP-1 indicates a very strong capacity to pay
principal and interest. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation. An SP-2
designation indicates a satisfactory capacity to pay principal and interest. An
SP-3 designation indicates speculative capacity to pay principal and interest.

PROSPECTUS DATED JULY 2, 1997
 
- --------------------------------------------------------------------------------
 
Prudential Municipal Bond Fund (the Fund) is an open-end, diversified,
management investment company, or mutual fund, consisting of three separate
portfolios--the High Yield Series, the Insured Series and the Intermediate
Series. Each Series operates as a separate fund with its own investment
objectives. Only shares of the Intermediate Series (the Series) are offered
through this Prospectus. The investment objective of the Intermediate Series is
to provide a high level of income that is eligible for exclusion from federal
income taxes consistent with the preservation of capital. Although the Series
will seek income that is eligible for exclusion from federal income taxes, a
portion of the dividends and distributions paid by the Series may be treated as
a preference item for purposes of the alternative minimum tax. The Series seeks
to achieve its objective through the investment policies described in this
Prospectus. There can be no assurance that the Series' investment objectives
will be achieved. See "How the Fund Invests--Investment Objectives and
Policies."
 
Subject to the limitations described herein, the Series may utilize derivatives,
including buying and selling futures contracts for the purpose of hedging its
portfolio securities. See "How the Fund Invests--Investment Objectives and
Policies."
 
The Fund's address is Gateway Center Three, 100 Mulberry Street, Newark, New
Jersey 07102-4077, and its telephone number is (800) 225-1852.
 
This Prospectus sets forth concisely the information about the Fund and the
Series that a prospective investor should know before investing. Additional
information about the Fund has been filed with the Securities and Exchange
Commission (SEC) in a Statement of Additional Information, dated July 2, 1997,
which information is incorporated herein by reference (is legally considered a
part of this Prospectus) and is available without charge upon request to the
Fund at the address or telephone number noted above.
- --------------------------------------------------------------------------------
 
INVESTORS ARE ADVISED TO READ THIS PROSPECTUS AND RETAIN IT FOR FUTURE
REFERENCE.
- --------------------------------------------------------------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                                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 MUNICIPAL BOND FUND?
  Prudential Municipal Bond Fund 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. The Fund is comprised of three separate
portfolios--the High Yield Series, the Insured Series and the Intermediate
Series. Only shares of the Intermediate Series are offered through this
Prospectus.
WHAT IS THE SERIES' INVESTMENT OBJECTIVE?
  The investment objective of the Series is to provide a high level of income
that is eligible for exclusion from federal income taxes consistent with the
preservation of capital. There can be no assurance that the Series' objective
will be achieved. See "How the Fund Invests--Investment Objectives and Policies"
at page 9.
WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?
  In seeking to achieve its objective, the Series will under normal
circumstances invest primarily in municipal obligations with maturities between
3 and 15 years and will have a dollar-weighted average portfolio maturity of
more than 3 and less than 10 years. Generally, the yield earned on longer-term
municipal obligations is greater than that earned on similar obligations with
shorter maturities. However, obligations with longer maturities are subject to
greater market risk due to larger fluctuations in value given specific changes
in the level of interest rates relative to the value of shorter-term
obligations. See "How the Fund Invests-- Investment Objectives and Policies" at
page 9. The Series may purchase and sell derivatives, including certain
financial futures contracts and options thereon, for hedging purposes. These
activities may be considered speculative and may result in higher risks and
costs to the Series. See "How the Fund Invests--Hedging Strategies--Risks of
Hedging Strategies" at page 12. As with an investment in any mutual fund, an
investment in this Series can decrease in value and you can lose money.
WHO MANAGES THE FUND?
  Prudential Investments Fund Management LLC (PIFM 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 average daily net assets of the Series up to $1 billion and .45 of
1% of the average daily net assets of the Series in excess of $1 billion. As of
May 31, 1997, PIFM served as manager or administrator to 62 investment
companies, including 40 mutual funds, with aggregate assets of approximately $56
billion. The Prudential Investment Corporation, which does business under the
name 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 PIFM. See "How the Fund is
Managed--Manager" at page 15.
WHO DISTRIBUTES THE SERIES' SHARES?
  Prudential Securities Incorporated (Prudential Securities or PSI), a major
securities underwriter and securities and commodities broker, acts as the
Distributor of the Series' shares. PSI 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 of the Series, is paid an annual
distribution and service fee which is currently being charged at the rate of .50
of 1% of the average daily net assets of the Class B shares of the Series and is
paid an annual distribution and service fee which is currently being charged at
the rate of .75 of 1% of the average daily net assets of the Class C shares of
the Series. Prudential Securities incurs the expense of distributing the Series'
Class Z shares under a distribution agreement with the Fund, none of which is
reimbursed or paid for by the Fund. See "How the Fund is Managed--Distributor"
at page 16.

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
for Class A, Class B and Class C shares. Class Z shares are not subject to any
minimum investment requirements. There is no minimum investment requirement for
certain employee savings plans. 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 23 and "Shareholder
Guide--Shareholder Services" at page 33.
HOW DO I PURCHASE SHARES?
  You may purchase shares of the Series 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). Class Z shares are offered to a
limited group of investors at net asset value without any sales charge. See "How
the Fund Values its Shares" at page 19 and "Shareholder Guide--How to Buy Shares
of the Fund" at page 23.
WHAT ARE MY PURCHASE ALTERNATIVES?
  The Series offers four classes of shares through this Prospectus:
 
<TABLE>
<S>                 <C>
- - 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 do not
                    convert to another class.
- - Class Z Shares:   Sold without either an initial or contingent deferred sales
                    charge to a limited group of investors. Class Z shares are
                    not subject to any ongoing service or distribution expenses.
</TABLE>
 
  See "Shareholder Guide--Alternative Purchase Plan" at page 25.
HOW DO I SELL MY SHARES?
  You may redeem your shares 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 28.
HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
  The Series expects to declare daily and pay monthly dividends of net
investment income, if any, and make distributions of any net capital gains at
least annually. Dividends and distributions will be automatically reinvested in
additional shares of the Series at NAV without a sales charge unless you request
that they be paid to you in cash. See "Taxes, Dividends and Distributions" at
page 20.

- ------------------
 (a) 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 Series may not exceed 6.25% of total gross
     sales, subject to certain exclusions. This 6.25% limitation is imposed on
     each class of the Series rather than on a per shareholder basis. Therefore,
     long-term shareholders of the Series 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."
 (b) Class B shares will automatically convert to Class A shares approximately
     seven years after purchase. See "Shareholder Guide--Conversion Feature--
     Class B Shares."
 (c) Based on expenses incurred during the fiscal year ended April 30, 1997,
     without taking into account the management fee waiver. At the current level
     of management fee waiver (10%), Management Fees would be .45% for all
     classes for the Series and Total Fund Operating Expenses for Class A, B, C,
     and Class Z shares would be 1.15%, 1.55%, 1.80% and 1.05%, respectively.
 (d) Although the Class A and Class C Distribution and Service Plans provide
     that the Series may pay a distribution fee of up to .30 of 1% and 1% 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
     the Class A and Class C shares of the Series to no more than .10 of 1% and
     .75 of 1% of the average daily net assets of the Class A and Class C
     shares, respectively, for the fiscal year ending April 30, 1998. Total Fund
     Operating Expenses of the Class A and Class C shares without such
     limitation would be 1.40% and 2.10%, respectively. See "How the Fund is
     Managed--Distributor."
 (e) Estimated based on expenses expected to have been incurred if Class Z
     shares had been in existence throughout the fiscal year ended April 30,

                              HOW THE FUND INVESTS
 
INVESTMENT OBJECTIVES AND POLICIES
 
  THE INVESTMENT OBJECTIVE OF THE SERIES IS TO PROVIDE A HIGH LEVEL OF INCOME
THAT IS ELIGIBLE FOR EXCLUSION FROM FEDERAL INCOME TAXES CONSISTENT WITH THE
PRESERVATION OF CAPITAL. THERE CAN BE NO ASSURANCE THAT SUCH OBJECTIVE WILL BE
ACHIEVED. See "Investment Objectives and Policies" in the Statement of
Additional Information. Although the Series will seek income that is eligible
for exclusion from federal income taxes, a portion of the dividends and
distributions paid by the Series may be treated as a preference item for
purposes of the alternative minimum tax. See "Taxes, Dividends and
Distributions."
 
  As with an investment in any mutual fund, an investment in this Series can
decrease in value and you can lose money.
 
  THE SERIES' INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE, MAY
NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE
OUTSTANDING VOTING SECURITIES OF THE SERIES AS DEFINED IN THE INVESTMENT COMPANY
ACT OF 1940, AS AMENDED (THE INVESTMENT COMPANY ACT). POLICIES OF THE SERIES
THAT ARE NOT FUNDAMENTAL MAY BE MODIFIED BY THE TRUSTEES.
 
  THE SERIES WILL SEEK TO ACHIEVE ITS INVESTMENT OBJECTIVE BY INVESTING IN A
PORTFOLIO OF OBLIGATIONS ISSUED BY OR ON BEHALF OF STATES, TERRITORIES AND
POSSESSIONS OF THE UNITED STATES AND THE DISTRICT OF COLUMBIA AND THEIR
POLITICAL SUBDIVISIONS, AGENCIES AND INSTRUMENTALITIES, THE INTEREST ON WHICH IS
GENERALLY ELIGIBLE FOR EXCLUSION FROM FEDERAL INCOME TAXATION (MUNICIPAL
OBLIGATIONS OR MUNICIPAL SECURITIES). THE PORTFOLIO SECURITIES HELD BY THE
SERIES WILL VARY WITH RESPECT TO YIELD, MARKET PRICE VOLATILITY AND QUALITY.
Generally, municipal obligations with longer maturities produce higher yields
and are subject to greater price fluctuations as a result of changes in interest
rates (market risk) than municipal obligations with shorter maturities. The
prices of municipal obligations vary inversely with interest rates. In addition,
lower rated municipal obligations typically provide a higher yield than higher
rated municipal obligations of similar maturity. However, lower rated municipal
obligations are also subject to a greater degree of risk with respect to the
ability of the issuer to meet the principal and interest payments on the
obligations (credit risk) and may also be subject to greater price volatility
due to the market perceptions of the creditworthiness of the issuer. Insurance
policies may be obtained to insure against credit risk, but not against market
risk.
 
  THE SERIES WILL INVEST PRIMARILY IN MUNICIPAL OBLIGATIONS WITH MATURITIES
BETWEEN 3 AND 15 YEARS AND WILL HAVE A DOLLAR-WEIGHTED AVERAGE PORTFOLIO
MATURITY OF MORE THAN 3 AND LESS THAN 10 YEARS. ALL OF THE MUNICIPAL OBLIGATIONS
HELD BY THE SERIES WILL BE RATED AT LEAST BAA BY MOODY'S INVESTORS SERVICE
(MOODY'S) OR BBB BY STANDARD & POOR'S RATINGS GROUP (S&P) OR A SIMILAR
NATIONALLY RECOGNIZED STATISTICAL RATING ORGANIZATION (NRSRO) AT THE TIME OF
PURCHASE OR BE NON-RATED OBLIGATIONS OF COMPARABLE QUALITY IN THE OPINION OF THE
FUND'S INVESTMENT ADVISER. Securities rated Baa by Moody's or BBB by S&P have
speculative characteristics and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with high grade bonds. Subsequent to its
purchase by the Series, a municipal obligation may be assigned a lower rating or
cease to be rated. Such an event would not require the elimination of the issue
from the portfolio, but the investment adviser will consider such an event in
determining whether the Series should continue to hold the security in its
portfolio. Under normal circumstances, at least 60% of the municipal obligations
purchased by the Series will be rated A or better by Moody's or S&P or a similar
NRSRO.
 
  For purposes of determining the dollar-weighted average portfolio maturity of
the Series' portfolio, the maturity of a municipal security will be its ultimate
maturity, unless it is probable that the issuer of the security will take
advantage of maturity-shortening devices such as a call, refunding or redemption
provision, in which case the maturity date will be the date on which it is
probable
 
                                       9
<PAGE>
that the security will be called, refunded or redeemed. If the municipal
security includes the right to demand payment, the maturity of the security for
purposes of determining the Series' dollar-weighted average portfolio maturity
will be the period remaining until the principal amount of the security can be
recovered by exercising the right to demand payment.
 
  GENERALLY, THE YIELD EARNED ON LONGER-TERM MUNICIPAL OBLIGATIONS IS GREATER
THAN THAT EARNED ON SIMILAR OBLIGATIONS WITH SHORTER MATURITIES. HOWEVER,
OBLIGATIONS WITH LONGER MATURITIES ARE SUBJECT TO GREATER MARKET RISK. Given a
specific change in the level of interest rates, the value of longer-term
obligations will fluctuate relatively more than the value of shorter-term
obligations. For example, 30-year municipal obligations typically yield 60-90
basis points (.60%-.90%) more than 10-year obligations and have 60-70% more
price volatility (market risk) than 10-year obligations.
 
  THE SERIES INTENDS TO INVEST IN LONGER-TERM, HIGHER YIELDING OBLIGATIONS AND
REDUCE THE GREATER MARKET RISK OF SUCH OBLIGATIONS THROUGH THE USE OF FINANCIAL
FUTURES CONTRACTS. SPECIFICALLY, THE SERIES WILL INVEST IN MUNICIPAL OBLIGATIONS
WITH MATURITIES OF BETWEEN 5 AND 30 YEARS AND SIMULTANEOUSLY HEDGE THE PRICE
VOLATILITY OF SUCH OBLIGATIONS THROUGH THE SALE OF FUTURES CONTRACTS. RATHER
THAN HEDGING THE MUNICIPAL OBLIGATION ENTIRELY, THE SERIES WILL SELL FUTURES
CONTRACTS IN SUFFICIENT AMOUNTS SO THAT THE DOLLAR-WEIGHTED AVERAGE MATURITY OF
THE COMBINED MUNICIPAL OBLIGATION/ FUTURES POSITION WILL BE MORE THAN 3 AND LESS
THAN 10 YEARS. IN THIS MANNER, THE INVESTMENT ADVISER WILL CREATE A "SYNTHETIC
OBLIGATION" THROUGH THE CONSTRUCTION OF A PARTIALLY HEDGED LONGER-TERM
OBLIGATION POSITION.
 
  The Series' investment adviser intends to create such synthetic obligation
positions when, in its opinion, the Series will realize one or more of the
following benefits compared to buying municipal obligations with shorter
maturities: (a) greater market liquidity; (b) lower transaction costs; (c)
greater expected capital appreciation or enhanced preservation of capital; or
(d) higher yields.
 
  In the municipal securities market, most new issues are structured with many
serial maturities that are relatively small in principal amount and one or
several longer-term maturities that are relatively large in principal amount.
Therefore, long-term municipal obligations typically have greater liquidity and
the associated transaction costs are relatively less than obligations with
maturities of 3 to 15 years.
 
  It is expected that synthetic obligation positions will often provide greater
returns than actual intermediate maturity municipal obligations. This can occur
when interest rate futures contracts are relatively overpriced in relation to
the current prices of municipal obligations, so that the sale of the futures
contracts, as part of a synthetic position, would be advantageous to the Series.
Synthetic positions can also be more attractive to the Series when the
investment adviser expects yields on longer-term municipal obligations to
decrease more (or increase less) than yields on medium-term municipal
obligations. If such expectations are correct, the net capital appreciation of
the synthetic obligation position should exceed (or the price decline be less
than) that of an actual intermediate-term municipal obligation.
 
  THERE IS NO ASSURANCE THAT THE SYNTHETIC OBLIGATION POSITION WILL TRADE LIKE
AN INTERMEDIATE-TERM MUNICIPAL OBLIGATION. ANY USE OF FUTURES CONTRACTS INVOLVES
THE RISK OF IMPERFECT CORRELATION IN MOVEMENTS IN THE PRICE OF THE FUTURES
CONTRACTS AND MOVEMENTS IN THE PRICE OF THE SECURITY BEING HEDGED. FURTHERMORE,
THE SERIES' ABILITY TO CREATE SYNTHETIC OBLIGATIONS IS SUBJECT TO VARIOUS OTHER
LIMITATIONS. See "Hedging Strategies--Futures Contracts and Options Thereon"
below.
 
  THE SERIES ALSO MAY USE FUTURES CONTRACTS TO HEDGE AGAINST OVERALL MARKET RISK
OF THE ENTIRE PORTFOLIO, as described under "Hedging Strategies--Futures
Contracts and Options Thereon" below.
 
  BORROWING
 
  The Series may borrow an amount equal to no more than 33 1/3% of the value of
its total assets (computed at the time the loan is made) for temporary,
extraordinary or emergency purposes and to take advantage of investment
opportunities or for the clearance of transactions. The Series may pledge up to
33 1/3% of the value of its total assets to secure these borrowings. If the
Series' asset coverage for borrowings falls below 300%, the Series will take
prompt action to reduce its borrowings. If the Series borrows to
 
                                       10
<PAGE>
invest in securities, any investment gains made on the securities in excess of
interest paid on the borrowing will cause the net asset value of the shares to
rise faster than would otherwise be the case. On the other hand, if the
investment performance of the additional securities purchased fails to cover
their cost (including any interest paid on the money borrowed) to the Series,
the net asset value of the Series' shares will decrease faster than would
otherwise be the case. This is the speculative factor known as "leverage." Money
borrowed for leveraging will be subject to interest costs which may or may not
be recovered by appreciation of the securities purchased and may exceed the
income from the securities purchased. In addition, the Fund may be required to
maintain minimum average balances in connection with such borrowing or pay a
commitment fee to maintain a line of credit which would increase the cost of
borrowing over the stated interest rate.
 
HEDGING STRATEGIES
 
FUTURES CONTRACTS AND OPTIONS THEREON
 
  THE SERIES IS AUTHORIZED TO PURCHASE AND SELL CERTAIN DERIVATIVES, INCLUDING
FINANCIAL FUTURES CONTRACTS (FUTURES CONTRACTS) AND OPTIONS THEREON FOR THE
PURPOSE OF ATTEMPTING TO HEDGE ITS INVESTMENT IN MUNICIPAL OBLIGATIONS AGAINST
FLUCTUATIONS IN VALUE CAUSED BY CHANGES IN PREVAILING MARKET INTEREST RATES AND
ATTEMPTING TO HEDGE AGAINST INCREASES IN THE COST OF SECURITIES THE SERIES
INTENDS TO PURCHASE. THE SERIES, AND THUS THE INVESTOR, MAY LOSE MONEY THROUGH
ANY UNSUCCESSFUL USE OF THESE STRATEGIES. In that regard, the Series may sell
futures contracts to create "synthetic positions" by partially hedging
longer-term obligation positions. See "Investment Objectives and Policies"
above. The successful use of futures contracts and options thereon by the Series
involves additional transaction costs, is subject to various risks and depends
upon the investment adviser's ability to predict the direction of the market and
interest rates.
 
  A FUTURES CONTRACT OBLIGATES THE SELLER OF A CONTRACT TO DELIVER TO THE
PURCHASER OF A CONTRACT CASH EQUAL TO A SPECIFIC DOLLAR AMOUNT TIMES THE
DIFFERENCE BETWEEN THE VALUE OF A SPECIFIC FIXED-INCOME SECURITY OR INDEX AT THE
CLOSE OF THE LAST TRADING DAY OF THE CONTRACT AND THE PRICE AT WHICH THE
AGREEMENT IS MADE. No physical delivery of the underlying securities is made.
The Series will engage in transactions in only those futures contracts and
options thereon that are traded on a commodities exchange or a board of trade.
 
  THE SERIES INTENDS TO ENGAGE IN FUTURES CONTRACTS AND OPTIONS THEREON AS A
HEDGE AGAINST CHANGES, RESULTING FROM MARKET CONDITIONS, IN THE VALUE OF
SECURITIES WHICH ARE HELD IN THE SERIES' PORTFOLIO OR WHICH THE SERIES INTENDS
TO PURCHASE, IN ACCORDANCE WITH THE RULES AND REGULATIONS OF THE COMMODITY
FUTURES TRADING COMMISSION (THE CFTC). The Series also intend to engage in such
transactions when they are economically appropriate for the reduction of risks
inherent in the ongoing management of the Series. The Series may purchase and
sell futures contracts and options thereon for bona fide hedging transactions,
except that the Series may purchase and sell futures contracts and options
thereon for any other purpose to the extent that the aggregate initial margin
and option premiums do not exceed 5% of the liquidation value of the Fund's
total assets. In addition, the Series may not purchase or sell futures contracts
or purchase options thereon if, immediately thereafter, the sum of initial and
net cumulative variation margin on outstanding futures contracts, together with
premiums paid on options thereon, would exceed 20% of the total assets of the
Series. There are no limitations on the percentage of a portfolio which may be
hedged and no limitations on the use of the Series' assets to cover futures
contracts and options thereon, except that the aggregate value of the
obligations underlying put options will not exceed 50% of the Series' assets.
 
  Currently, futures contracts are available on several types of fixed-income
securities, including U.S. Treasury Bonds and Notes, Government National
Mortgage Association modified pass-through mortgage-backed securities,
three-month U.S. Treasury Bills and bank certificates of deposit. Futures
contracts are also available on a municipal bond index, based on THE BOND BUYER
Municipal Bond Index, an index of 40 actively traded municipal bonds. The Series
may also engage in transactions in other futures contracts that become
available, from time to time, in other fixed-income securities or municipal bond
indices and in other options on such contracts if the investment adviser
believes such contracts and options would be appropriate for hedging investments
in municipal obligations.
 
                                       11
<PAGE>
  THERE CAN BE NO ASSURANCE THAT VIABLE MARKETS WILL CONTINUE OR THAT A LIQUID
SECONDARY MARKET WILL EXIST TO TERMINATE ANY PARTICULAR FUTURES CONTRACT AT ANY
SPECIFIC TIME. If it is not possible to close a futures position entered into by
the Series, the Series will continue to be required to make daily cash payments
of variation margin in the event of adverse price movements. In such a
situation, if the Series had insufficient cash, it might have to sell portfolio
securities to meet daily variation margin requirements at a time when it might
be disadvantageous to do so. The inability to close futures positions also could
have an adverse impact on the ability of the Series to hedge effectively. There
is also a risk of loss by the Series of margin deposits in the event of
bankruptcy of a broker with whom the Series has an open position in a futures
contract.
 
  THE SUCCESSFUL USE OF FUTURES CONTRACTS AND OPTIONS THEREON BY THE SERIES IS
SUBJECT TO VARIOUS ADDITIONAL RISKS. Any use of futures transactions involves
the risk of imperfect correlation in movements in the price of futures contracts
and movements in interest rates and, in turn, the prices of the securities that
are the subject of the hedge. If the price of the futures contract moves more or
less than the price of the security that is the subject of the hedge, the Series
will experience a gain or loss that will not be completely offset by movements
in the price of the security. The risk of imperfect correlation is greater where
the securities underlying futures contracts are taxable securities (rather than
municipal securities), are issued by companies in different market sectors or
have different maturities, ratings or geographic mixes than the security being
hedged. In addition, the correlation may be affected by additions to or
deletions from the index which serves as the basis for a futures contract.
Finally, if the price of the security that is subject to the hedge were to move
in a favorable direction, the advantage to the Series would be partially offset
by the loss incurred on the futures contract.
 
  THE SERIES' ABILITY TO ENTER INTO AND CLOSE OUT FUTURES CONTRACTS AND OPTIONS
THEREON IS LIMITED BY THE REQUIREMENTS OF THE INTERNAL REVENUE CODE OF 1986, AS
AMENDED (THE INTERNAL REVENUE CODE), FOR QUALIFICATION AS A REGULATED INVESTMENT
COMPANY. See "Taxes, Dividends and Distributions" in the Statement of Additional
Information.
 
  RISKS OF HEDGING STRATEGIES
 
  PARTICIPATION IN THE OPTIONS OR FUTURES MARKETS INVOLVES INVESTMENT RISKS AND
TRANSACTION COSTS TO WHICH THE SERIES WOULD NOT BE SUBJECT ABSENT THE USE OF
THESE STRATEGIES. THE SERIES, AND THUS THE INVESTOR, MAY LOSE MONEY THROUGH ANY
UNSUCCESSFUL USE OF THESE STRATEGIES. If the investment adviser's prediction of
movements in the direction of the securities and interest rate markets is
inaccurate, the adverse consequences to the Series may leave the Series in a
worse position than if such strategies were not used. Risks inherent in the use
of futures contracts and options thereon include (1) dependence on the
investment adviser's ability to predict correctly movements in the direction of
interest rates and securities prices or the movement in indicies; (2) imperfect
correlation between the price of futures contracts and options thereon and
movements in the prices of the securities being hedged; (3) the fact that skills
needed to use these strategies are different from those needed to select
portfolio securities; (4) the possible absence of a liquid secondary market for
any particular instrument at any time; (5) the possible need to defer closing
out certain hedged positions to avoid adverse tax consequences; and (6) the
possible inability of the Series to purchase or sell a portfolio security at a
time that otherwise would be favorable for it to do so, or the possible need for
the Series to sell a portfolio security at a disadvantageous time, due to the
need for the Series to maintain "cover" or to segregate securities in connection
with hedging transactions. See "Investment Objectives and Policies" and "Taxes,
Dividends and Distributions" in the Statement of Additional Information.
 
OTHER INVESTMENTS AND POLICIES
 
GENERAL
 
  MUNICIPAL SECURITIES INCLUDE BONDS AND NOTES ISSUED BY OR ON BEHALF OF STATES,
TERRITORIES AND POSSESSIONS OF THE UNITED STATES AND THEIR POLITICAL
SUBDIVISIONS, AGENCIES AND INSTRUMENTALITIES, THE INTEREST ON WHICH IS GENERALLY
ELIGIBLE FOR EXCLUSION FROM FEDERAL INCOME TAX. MUNICIPAL BONDS ARE TYPICALLY
ISSUED TO OBTAIN FUNDS FOR VARIOUS PUBLIC
 
                                       12
<PAGE>
PURPOSES, INCLUDING THE CONSTRUCTION OF A WIDE RANGE OF PUBLIC FACILITIES SUCH
AS AIRPORTS, BRIDGES, HIGHWAYS, HOUSING, HOSPITALS, MASS TRANSPORTATION,
SCHOOLS, STREETS, WATER AND SEWER WORKS AND GAS AND ELECTRIC UTILITIES.
MUNICIPAL NOTES GENERALLY ARE USED TO FINANCE SHORT-TERM CAPITAL NEEDS AND
TYPICALLY HAVE MATURITIES OF ONE YEAR OR LESS.
 
  THE SERIES MAY INVEST MORE THAN 5% OF ITS NET ASSETS IN FLOATING RATE AND
VARIABLE RATE SECURITIES, INCLUDING PARTICIPATION INTERESTS THEREIN. Floating
and variable rate securities normally have a rate of interest which is set as a
specific percentage of a designated base rate, such as the rate on Treasury
Bonds or Bills or the prime rate at a major commercial bank. These securities
also allow the holder to demand payment of the obligation on short notice at par
plus accrued interest, which amount may be more or less than the amount the
Series paid for them. Variable rate securities provide for a specified periodic
adjustment in the interest rate. The interest rate on floating rate securities
changes whenever there is a change in the designated base interest rate.
 
  The Series 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.
 
  The Series may purchase a rating from an NRSRO for non-rated securities. The
purchase of a rating is expected to enhance the value of the security for which
the rating is purchased. The cost of purchasing a rating is an expense of the
Series.
 
  DURING NORMAL MARKET CONDITIONS, THE ASSETS OF THE SERIES WILL BE INVESTED SO
THAT IT WILL HAVE AT LEAST 80% OF ITS NET ASSETS INVESTED IN MUNICIPAL
OBLIGATIONS. However, when the Series' investment adviser believes that market
conditions warrant a temporary defensive investment posture or when necessary to
meet large redemptions, the Series may hold more than 20% of its net assets in
cash, cash equivalents or investment grade taxable obligations, including
obligations that are generally exempt from state, but not federal, taxation. The
Series may invest in municipal cash equivalents, such as floating rate demand
notes, municipal commercial paper and general obligation and revenue notes, or
in taxable cash equivalents, such as certificates of deposit, bankers'
acceptances and time deposits or other short-term taxable investments, such as
repurchase agreements. The Series will treat an investment in a municipal bond
refunded with escrowed U.S. Government securities as U.S. Government securities
for purposes of the Investment Company Act's diversification requirements
provided certain conditions are met. See "Investment Objectives and
Policies--Other Investments and Policies" in the Statement of Additional
Information.
 
  WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
 
  The Series may purchase municipal obligations on a "when-issued" or "delayed
delivery" basis and may from time to time sell obligations on a 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 the
when-issued securities take place at a later date. Normally, the settlement date
occurs within one month of purchase. During the period between purchase and
settlement, no interest accrues to the purchaser. In the case of purchases by
the Series, the price that the Series 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 Series 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 Series 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 Series. If
the seller defaults in the sale, the Series could fail to realize the
appreciation, if any, that had occurred. The Series 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, having a value equal to or greater than the Series'
purchase commitments.
 
  As in the case of purchases, the price of the municipal obligations sold on a
delayed delivery basis is determined at the time of the commitment. The price
that the Series may be required to accept on the settlement date may be less
than the market value of the obligation on that date.
 
                                       13
<PAGE>
  The Series may also purchase municipal forward contracts. A municipal forward
contract is a municipal security which is purchased on a when-issued basis with
delivery taking place up to five years from the date of purchase. The investment
adviser will monitor the liquidity, value, credit quality and delivery of the
security under the supervision of the Trustees.
 
  MUNICIPAL LEASE OBLIGATIONS
 
  The Series may 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) or the
acquisition of equipment. 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 Trustees. See "Illiquid Securities" below.
 
  LIQUIDITY PUTS
 
  The Series may purchase and exercise puts on municipal bonds and notes without
limit. Puts give the Series the right to sell the securities at a specified
exercise price on a specified date. Puts may be acquired to reduce the
volatility of the market value of the securities subject to the puts, but the
acquisition of the puts may involve an additional cost to the Series. See
"Investment Objectives and Policies" in the Statement of Additional Information.
 
  REPURCHASE AGREEMENTS
 
  The Series may on occasion enter into repurchase agreements, whereby the
seller of a security agrees to repurchase that security from the Series at a
mutually agreed-upon time and price. The period of maturity is usually quite
short, possibly overnight or a few days, although it may extend over a number of
months. The resale price is in excess of the purchase price, reflecting an
agreed-upon rate of return effective for the period of time the Series' money is
invested in the security. The Series' repurchase agreements will at all times be
fully collateralized in an amount at least equal to the resale price. The
instruments held as collateral are valued daily, and if the value of the
instruments declines, the Series will require additional collateral. If the
seller defaults and the value of the collateral securing the repurchase
agreement declines, the Series may incur a loss. The Series participates in a
joint repurchase account with other investment companies managed by PIFM
pursuant to an order of the Securities and Exchange Commission (SEC).
 
  ILLIQUID SECURITIES
 
  The Series may hold up to 15% of its net assets in illiquid securities,
including repurchase agreements which have a maturity of longer than seven days,
securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable. Securities,
including municipal lease obligations, that have a readily available market are
not considered illiquid for purposes of this limitation. The investment adviser
will monitor the liquidity of such restricted securities under the supervision
of the Trustees. The Series' investment in Rule 144A securities could have the
effect of increasing illiquidity to the extent that qualified institutional
buyers become, for a limited time, uninterested in purchasing Rule 144A
securities. See "Investment Restrictions" in the Statement of Additional
Information. Repurchase agreements subject to demand are deemed to have a
maturity equal to the applicable notice period.
 
  Municipal lease obligations will not be considered illiquid for purposes of
the Series' 15% limitation on illiquid securities provided the investment
adviser determines that there is a readily available market for such securities.
In reaching liquidity decisions, the investment adviser will consider, INTER
ALIA, the following factors: (1) the frequency of trades and quotes for the
security; (2) the number of dealers wishing to purchase or sell the security and
the number of other potential purchasers; (3) dealer undertakings to make a
market in the security; and (4) the nature of the security and the nature of the
marketplace trades (E.G., the time needed to dispose of the security, the method
of soliciting offers and the mechanics of the transfer). With respect to
 
                                       14
<PAGE>
municipal lease obligations, the investment adviser also considers: (1) the
willingness of the municipality to continue, annually or biannually, to
appropriate funds for payment of the lease; (2) the general credit quality of
the municipality and the essentiality to the municipality of the property
covered by the lease; (3) in the case of unrated municipal lease obligations, an
analysis of factors similar to that performed by nationally recognized
statistical rating organizations in evaluating the credit quality of a municipal
lease obligation, including (i) whether the lease can be cancelled; (ii) if
applicable, what assurance there is that the assets represented by the lease can
be sold; (iii) the strength of the lessee's general credit (E.G., its debt,
administrative, economic and financial characteristics); (iv) the likelihood
that the municipality will discontinue appropriating funding for the leased
property because the property is no longer deemed essential to the operations of
the municipality (E.G., the potential for an event of nonappropriation); (v) the
legal recourse in the event of failure to appropriate; and (4) any other factors
unique to municipal lease obligations as determined by the investment adviser.
 
  SECURITIES LENDING
 
  The Series is permitted to lend its portfolio securities. See "Investment
Objectives and Policies--Municipal Securities-- Lending of Securities" in the
Statement of Additional Information.
 
  PORTFOLIO TURNOVER
 
  The Series does not expect to trade in securities for short-term gain. It is
anticipated that the annual portfolio turnover rate will not exceed 150%. The
portfolio turnover rate is calculated by dividing the lesser of sales or
purchases of portfolio securities by the average monthly value of the Series'
portfolio securities, excluding securities having a maturity at the date of
purchase of one year or less.
 
INVESTMENT RESTRICTIONS
 
  The Series 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
Series' outstanding voting securities, as defined in the Investment Company Act.
See "Investment Restrictions" in the Statement of Additional Information.
 
                            HOW THE FUND IS MANAGED
 
  THE FUND HAS TRUSTEES WHO, IN ADDITION TO OVERSEEING THE ACTIONS OF THE FUND'S
MANAGER, SUBADVISER AND DISTRIBUTOR, AS SET FORTH BELOW, DECIDE UPON MATTERS OF
GENERAL POLICY. THE FUND'S MANAGER CONDUCTS AND SUPERVISES THE DAILY BUSINESS
OPERATIONS OF THE FUND. THE FUND'S SUBADVISER FURNISHES DAILY INVESTMENT
ADVISORY SERVICES.
 
  For the fiscal year ended April 30, 1997, the total expenses as a percentage
of average net assets were 1.15%, 1.55%, 1.80% and 1.05% of the Class A, Class
B, Class C and Class Z shares, respectively, of the Series. See "Financial
Highlights."
 
MANAGER
 
  PRUDENTIAL INVESTMENTS FUND MANAGEMENT LLC (PIFM OR THE MANAGER), GATEWAY
CENTER THREE, NEWARK, NEW JERSEY 07102, IS THE MANAGER OF THE FUND AND IS
COMPENSATED FOR ITS SERVICES AT AN ANNUAL RATE OF .50 OF 1% OF THE AVERAGE DAILY
NET ASSETS OF THE SERIES UP TO $1 BILLION AND .45 OF 1% OF THE AVERAGE DAILY NET
ASSETS OF THE SERIES IN EXCESS OF $1 BILLION. PIFM, which changed its name from
Prudential Mutual Fund Management LLC, effective May 1, 1997, is organized as a
New York limited liability company. It is the successor to Prudential Mutual
Fund Management, Inc., which transferred its assets to PIFM in September 1996.
For the fiscal year ended April 30, 1997, PIFM received a management fee of .45%
of average daily net assets on behalf of the Series. See "Manager" in the
Statement of Additional Information.
 
                                       15
<PAGE>
  PIFM may from time to time waive its management fee and subsidize operating
expenses of the Series. PIFM has agreed to waive 10% of its management fee (.05
of 1% of average net assets, as annualized). See "Fund Expenses." The Fund is
not required to reimburse PIFM for such fee waiver. Fee waivers and expense
subsidies will increase the Series' yield and total return. See "How the Fund
Calculates Performance."
 
  As of May 31, 1997, PIFM served as the manager to 40 open-end investment
companies, constituting all of the Prudential Mutual Funds, and as manager or
administrator to 22 closed-end investment companies with aggregate assets of
approximately $56 billion.
 
  UNDER THE MANAGEMENT AGREEMENT WITH THE FUND, PIFM MANAGES THE INVESTMENT
OPERATIONS OF EACH SERIES OF THE FUND AND ALSO ADMINISTERS THE FUND'S BUSINESS
AFFAIRS. See "Manager" in the Statement of Additional Information.
 
  UNDER A SUBADVISORY AGREEMENT BETWEEN PIFM AND THE PRUDENTIAL INVESTMENT
CORPORATION (PIC), DOING BUSINESS AS PRUDENTIAL INVESTMENTS (PI, THE SUBADVISER
OR THE INVESTMENT ADVISER), PI FURNISHES INVESTMENT ADVISORY SERVICES IN
CONNECTION WITH THE MANAGEMENT OF THE FUND AND IS REIMBURSED BY PIFM FOR ITS
REASONABLE COSTS AND EXPENSES INCURRED IN PROVIDING SUCH SERVICES. Under the
Management Agreement, PIFM continues to have responsibility for all investment
advisory services pursuant to the Management Agreement and supervises PI's
performance of such services.
 
  The current portfolio manager of the Series is Marie Conti, a Vice President
of PIFM, who has responsibility for the day-to-day management of the Series'
portfolio. Ms. Conti has managed the Series' portfolio since 1990 and has been
employed by PIC as a portfolio manager since September 1989 and prior thereto
was employed in an administrative capacity at PIC since August 1988.
 
  PIFM and PIC are wholly-owned subsidiaries of The Prudential Insurance Company
of America (Prudential), a major diversified insurance and financial services
company.
 
DISTRIBUTOR
 
  PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES, PSI OR THE
DISTRIBUTOR), ONE SEAPORT PLAZA, NEW YORK, NEW YORK 10292, IS A CORPORATION
ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND SERVES AS THE DISTRIBUTOR
OF THE SHARES OF EACH SERIES 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, 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 CLASS A, CLASS B AND CLASS C SHARES. Prudential
Securities incurs the expenses of distributing the Series' Class Z shares under
the Distribution Agreement, none of which is reimbursed by or paid for by the
Fund. 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.
 
  Under the Plans, the Series 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 SERIES 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 ASSETS OF THE CLASS A SHARES. The
Class A
 
                                       16
<PAGE>
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 up to .25 of 1%) may not exceed .30 of 1% of the average
daily net assets of the Class A shares. 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
April 30, 1998.
 
  UNDER THE CLASS B AND CLASS C PLANS, THE SERIES 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 shareholders 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 April 30, 1998. Prudential Securities also receives
contingent deferred sales charges from certain redeeming shareholders. See
"Shareholder Guide--How to Sell Your Shares--Contingent Deferred Sales Charges."
 
  For the fiscal year ended April 30, 1997, the Series paid distribution
expenses of .10%, .50% and .75% of the average daily net assets of the Class A,
Class B and Class C shares, respectively. The Series 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 Class A, Class B and Class C
shares of the Series will be allocated to each such class based upon the ratio
of sales of each such class to the sales of Class A, Class B and Class C shares
of the Series other than expenses allocable to a particular class. The
distribution fee and sales charge of one class will not be used to subsidize the
sale of another class.
 
  Each Plan provides that it shall continue in effect from year to year provided
that a majority of the Trustees of the Fund, including a majority of the
Trustees 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
Trustees), vote annually to continue the Plan. Each Plan may be terminated at
any time by vote of a majority of the Rule 12b-1 Trustees or of a majority of
the outstanding shares of the applicable class of the Series. The Series will
not be obligated to pay distribution and service fees incurred under any Plan if
it is terminated or not continued.
 
  In addition to distribution and service fees paid by the Series 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 Series (including
Class Z shares). 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. (the 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
 
                                       17
<PAGE>
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
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 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 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 (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 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 and Brokerage" in the
Statement of Additional Information.
 
CUSTODIAN AND TRANSFER AND DIVIDEND DISBURSING AGENT
 
  State Street Bank and Trust Company, One Heritage Drive, North Quincy,
Massachusetts 02171, serves as Custodian for the portfolio securities and cash
of the Series and, in that capacity, maintains certain financial and accounting
books and records pursuant to an agreement with the Fund. Its mailing address is
P.O. Box 1713, Boston, Massachusetts 02105.
 
  Prudential Mutual Fund Services LLC (PMFS), Raritan Plaza One, Edison, New
Jersey 08837, serves as Transfer Agent and Dividend Disbursing Agent and in
those capacities maintains certain books and records for the Fund. PMFS is a
wholly-owned subsidiary of PIFM. Its mailing address is P.O. Box 15005, New
Brunswick, New Jersey 08906-5005.

<PAGE>
                         HOW THE FUND VALUES ITS SHARES
 
  THE SERIES' NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING ITS
LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE REMAINDER BY THE
NUMBER OF OUTSTANDING SHARES. NAV IS CALCULATED SEPARATELY FOR EACH CLASS. THE
TRUSTEES HAVE FIXED THE SPECIFIC TIME OF DAY FOR THE COMPUTATION OF THE SERIES'
NET ASSET VALUE 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 Trustees. Securities may also be valued based on
values provided by a pricing service. See "Net Asset Value" in the Statement of
Additional Information.
 
  The Series 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 Series or days on which changes in
the value of the Series' portfolio securities do not materially affect the NAV.
 
  Although the legal rights of each class of shares are substantially identical,
the different expenses borne by each class will result in different dividends.
As long as the Series declares dividends daily, the NAV of the Class A, Class B,
Class C and Class Z shares will generally be the same. It is expected, however,
that the Series' dividends will differ by approximately the amount of any
distribution and or service fee expense accrual differential among the classes.
 
                      HOW THE FUND CALCULATES PERFORMANCE
 
  FROM TIME TO TIME THE FUND MAY ADVERTISE THE "YIELD," "TAX EQUIVALENT YIELD"
AND "TOTAL RETURN" (INCLUDING "AVERAGE ANNUAL" TOTAL RETURN AND "AGGREGATE"
TOTAL RETURN) OF THE SERIES IN ADVERTISEMENTS OR SALES LITERATURE. YIELD, TAX
EQUIVALENT YIELD AND TOTAL RETURN ARE CALCULATED SEPARATELY FOR CLASS A, CLASS
B, CLASS C AND CLASS Z 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 Series over a one-month or 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 Series. The "total return" shows how much an
investment in the Series would have increased (decreased) over a specified
period of time (I.E., one, five or ten years or since inception of the Series)
assuming that all distributions and dividends by the Series 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 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 Series also may
include comparative performance information in advertising or marketing its
shares. Such performance information may include data from Lipper Analytical
Services, Inc.,
 
                                       19
<PAGE>
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
Series' 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 SERIES HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, THE
SERIES WILL NOT BE SUBJECT TO FEDERAL INCOME TAXES ON ITS NET TAXABLE INVESTMENT
INCOME AND NET CAPITAL GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS.
TO THE EXTENT NOT DISTRIBUTED BY THE SERIES, NET TAXABLE INVESTMENT INCOME AND
CAPITAL GAINS ARE TAXABLE. See "Taxes, Dividends and Distributions" in the
Statement of Additional Information.
 
  To the extent the Series invests in taxable obligations, it will earn taxable
investment income. Also, to the extent the Series sells securities or engages in
hedging transactions in futures contracts and options thereon, it may earn both
short-term and long-term capital gain or loss. Capital gain or loss may also
arise upon the sale of municipal securities, as well as taxable obligations.
Under the Internal Revenue Code, special rules apply to the treatment of certain
options and futures contracts (Section 1256 contracts). At the end of each year,
such investments held by the Series will be required to be "marked to market"
for federal income tax purposes; that is, treated as having been sold at market
value. Sixty percent of any gain or loss recognized on these "deemed sales" and
on actual dispositions will be treated as long-term capital gain or loss, and
the remainder will be treated as short-term capital gain or loss. See "Taxes,
Dividends and Distributions" in the Statement of Additional Information.
 
  Gain or loss realized by the Series 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 Series 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 issue price of the security). The market
discount rule does not apply to any security that was acquired by the Series at
its original issue.
 
TAXATION OF SHAREHOLDERS
 
  In general, the character of tax-exempt interest distributed by the Series
will flow through as tax-exempt interest to its shareholders provided that 50%
or more of the value of its assets at the end of each quarter of its taxable
year is invested in state, municipal and other obligations, the interest on
which is excluded from gross income for federal income tax purposes. During
normal market conditions, at least 80% of the Series' net assets will be
invested in such obligations. See "How the Fund Invests--Other Investments and
Policies."
 
  Any dividends out of net taxable investment income, together with
distributions of net short-term gains (I.E., the excess of net short-term
capital gains over net long-term capital losses) distributed to shareholders,
will be taxable as ordinary income to the shareholder whether or not reinvested.
Any net 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
long-term capital gains 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 currently is 28%. The
maximum long-term capital gains rate for corporate shareholders is currently the
same as the maximum tax rate for ordinary income.
 
                                       20
<PAGE>
  Any gain or loss realized upon a sale, exchange or redemption of the Series'
shares by a shareholder who is not a dealer in securities will be treated as
long-term capital gain or loss if the shares have been held more than one year
and otherwise as short-term capital gain or loss. Any loss, however, with
respect to the sale, exchange or redemption of shares that are held for six
months or less will be disallowed to the extent of any exempt interest dividends
received by the shareholder with respect to such shares, and otherwise will be
treated as long-term capital loss to the extent of any capital gain
distributions received by the shareholder with respect to such shares.
 
  Any loss realized on a sale, redemption or exchange of shares of the Series by
a shareholder will be disallowed to the extent the shares are replaced within a
61-day period (beginning 30 days before the disposition of shares). Shares
purchased pursuant to the reinvestment of a dividend will constitute a
replacement of shares.
 
  A shareholder who acquires shares of the Series and sells or otherwise
disposes of such shares within 90 days of acquisition may not be allowed to
include certain sales charges incurred in acquiring such shares for purposes of
calculating gain or loss realized upon a sale or exchange of shares of the
Series.
 
  CERTAIN INVESTORS MAY INCUR FEDERAL ALTERNATIVE MINIMUM TAX LIABILITY AS A
RESULT OF THEIR INVESTMENT IN THE SERIES. Tax-exempt interest from certain
municipal obligations (I.E., certain private activity bonds issued after August
7, 1986) will be treated as an item of tax preference for purposes of the
alternative minimum tax. The Series anticipates that, under regulations to be
promulgated, items of tax preference incurred by a Series which has invested in
such municipal obligations will be attributed to the Series' shareholders,
although some portion of such items could be allocated to the Series itself.
Depending upon each shareholder's individual circumstances, the attribution of
items of tax preference incurred by a Series could result in liability for the
shareholder for the alternative minimum tax. Similarly, the Series could be
liable for the alternative minimum tax for items of tax preference attributed to
it.
 
  The Series intends to minimize its investment in municipal obligations of the
type that will produce items of tax preference.
 
  Distributions relating to interest on all municipal obligations will be
included in a corporate shareholder's current earnings for purposes of the
adjustment for current earnings for alternative minimum tax purposes. Corporate
shareholders should consult with their tax advisers with respect to this
potential adjustment.
 
  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.
 
  Shareholders are advised to consult their own tax advisers regarding specific
questions as to federal, state, local or foreign taxes. See "Taxes, Dividends
and Distributions" in the Statement of Additional Information.
 
WITHHOLDING TAXES
 
  Under the Internal Revenue Code, the Series is required to withhold and remit
to the U.S. Treasury 31% of redemption proceeds on the accounts of those
shareholders who fail to furnish their tax identification numbers on IRS Form
W-9 (or IRS Form W-8 in the case of certain foreign shareholders) with the
required certifications regarding the shareholders' status under the federal
income tax law. Withholding generally is also required on taxable dividends and
capital gains distributions made by the Series.
 
  Dividends of net investment income and distributions of net short-term capital
gains paid to a shareholder (including a shareholder acting as a nominee or
fiduciary) who is a nonresident alien individual, a foreign corporation or a
foreign partnership (foreign shareholder) are subject to a 30% (or lower treaty
rate) witholding tax upon the gross amount of the dividends unless the dividends
are effectively connected with a U.S. trade or business conducted by the foreign
shareholder. Capital gain dividends
 
                                       21
<PAGE>
paid to a foreign shareholder are generally not subject to withholding tax. A
foreign shareholder will, however, be required to pay U.S. income tax on any
dividends and capital gain distributions which are effectively connected with a
U.S. trade or business of the foreign shareholder.
 
DIVIDENDS AND DISTRIBUTIONS
 
  THE SERIES EXPECTS TO DECLARE DAILY AND PAY MONTHLY DIVIDENDS OF NET
INVESTMENT INCOME, IF ANY, AND MAKE DISTRIBUTIONS AT LEAST ANNUALLY OF ANY NET
CAPITAL GAINS. Dividends paid by the Series with respect to each class of
shares, to the extent 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 (other than Class Z) will bear its own distribution charges,
generally resulting in lower dividends for Class B and Class C shares in
relation to Class A shares and lower dividends for Class A shares in relation to
Class Z 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 SHARES OF THE SERIES
BASED ON THE NAV OF EACH CLASS ON THE PAYMENT DATE, OR SUCH OTHER DATE AS THE
TRUSTEES 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. If you hold shares through Prudential
Securities, you should contact your financial adviser to elect to receive
dividends and distributions in cash. 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.
 
  Any taxable dividends or 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 dividends or
distributions. Such dividends or distributions, although in effect a return of
invested principal, are subject to federal income taxes. Accordingly, prior to
purchasing shares of the Series, an investor should carefully consider the
impact of taxable dividends and capital gains distributions which are expected
to be or have been announced.
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
 
  THE FUND IS AN OPEN-END, MANAGEMENT INVESTMENT COMPANY COMPRISED OF THREE
SERIES WHICH WAS ORGANIZED UNDER THE LAWS OF MASSACHUSETTS ON NOVEMBER 3, 1986
AS AN UNINCORPORATED BUSINESS TRUST, A FORM OF ORGANIZATION THAT IS COMMONLY
CALLED A MASSACHUSETTS BUSINESS TRUST. THE FUND IS AUTHORIZED TO ISSUE AN
UNLIMITED NUMBER OF SHARES, DIVIDED INTO FOUR CLASSES, DESIGNATED CLASS A, CLASS
B, CLASS C AND CLASS Z. Each class of shares represents an interest in the same
assets of each Series and is identical in all respects except that (i) each
class is subject to different sales charges and distribution and/or service fees
(except for Class Z shares, which are not subject to any sales charges or
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 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, (iii) each class has a different exchange privilege, (iv) only
Class B shares have a conversion feature and (v) Class Z shares are offered
exclusively to a limited group of investors. See "How the Fund is
Managed--Distributor." In accordance with the Fund's Declaration of Trust, the
Trustees may authorize the creation of additional series and classes of shares
within such series, with such preferences, privileges, limitations and voting
and dividend rights as the Trustees may determine.

  Shares of the Series, 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 Series under certain circumstances as described
under "Shareholder Guide-- How to Sell Your Shares." Each share of each class of
each Series is equal as to earnings, assets and voting privileges, except as
noted above, and each class of shares (with the exception of Class Z shares,
which are not subject to any distribution or service fees) bears the expenses
related to the distribution of its shares. Except for the conversion feature
applicable to the Class B shares, there are no conversion, preemptive or other
subscription rights. In the event of liquidation, each share of beneficial
interest in the Series is entitled to its portion of all of the Series' assets
after all debt and expenses of the Series have been paid. Since Class B and
Class C shares generally bear higher distribution expenses than Class A shares,
the liquidation proceeds to shareholders of those classes are likely to be lower
than to Class A shareholders and to Class Z shareholders, whose shares are not
subject to any distribution and/or service fees. The Series' shares do not have
cumulative voting rights for the election of Trustees.
 
  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 TRUSTEES 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 TRUSTEES OR TO TRANSACT ANY OTHER BUSINESS.
 
  The Declaration of Trust and the By-Laws of the Fund are designed to make the
Fund similar in certain respects to a Massachusetts business corporation. The
principal distinction between a Massachusetts business corporation and a
Massachusetts business trust relates to shareholder liability. Under
Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Fund, which is not the case with a corporation. The Declaration of Trust of the
Fund provides that shareholders shall not be subject to any personal liability
for the acts or obligations of the Fund and that every written obligation,
contract, instrument or undertaking made by the Fund shall contain a provision
to the effect that the shareholders are not individually bound thereunder.

Shares."
 
                                       23
<PAGE>
  An investment in the Series may not be appropriate for tax-exempt or
tax-deferred investors. Such investors should consult their own tax advisers.
 
  The minimum initial investment is $1,000 for Class A and Class B shares and
$5,000 for Class C shares except that the minimum initial investment for Class C
shares may be waived from time to time. There is no minimum investment
requirement for Class Z shares. The minimum subsequent investment is $100 for
all classes, except for Class Z shares, for which there is no minimum. All
minimum investment requirements are waived for certain employee savings plans.
For purchases made through the Automatic Savings Accumulation Plan, the minimum
initial and subsequent investment is $50. See "Shareholder Services" below.
 
  Application forms can be obtained from PMFS, Prudential Securities or Prusec
or a selected dealer (Class A only). If a share certificate is desired, it must
be requested in writing for each transaction. Certificates are issued only for
full shares. Shareholders who hold their shares through Prudential Securities
will not receive share certificates.
 
  The Fund reserves the right to reject any purchase order (including an
exchange into the Series) or to suspend or modify the continuous offering of its
shares. See "How to Sell Your Shares" below.
 
  Your dealer is responsible for forwarding payment promptly to the Fund. The
Distributor reserves the right to cancel any purchase order for which payment
has not been received by the third business day following the investment.
 
  Transactions in Fund shares may be subject to postage and handling charges
imposed by your dealer.
 
  PURCHASE BY WIRE. For an initial purchase of shares of the Series by wire, you
must first telephone PMFS at (800) 225-1852 (toll-free) to receive an account
number. The following information will be requested: your name, address, tax
identification number, class election, dividend distribution election, amount
being wired and wiring bank. Instructions should then be given by you to your
bank to transfer funds by wire to State Street Bank and Trust Company, Boston,
Massachusetts, Custody and Shareholder Services Division, Attention: Prudential
Municipal Bond Fund (Intermediate Series), specifying on the wire the account
number assigned by PMFS and your name and identifying the class in which you are
eligible to invest (Class A, Class B, Class C or Class Z shares).
 
  If you arrange for receipt by State Street of Federal Funds prior to the
calculation of NAV (4:15 P.M., New York time), on a business day, you may
purchase shares of the Series as of that day. See "Net Asset Value" in the
Statement of Additional Information.
 
  In making a subsequent purchase order by wire, you should wire State Street
directly and should be sure that the wire specifies Prudential Municipal Bond
Fund (Intermediate Series), Class A, Class B, Class C or Class Z 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.

ALTERNATIVE PURCHASE PLAN
 
  THE SERIES OFFERS THROUGH THIS PROSPECTUS FOUR CLASSES OF SHARES (CLASS A,
CLASS B, CLASS C AND CLASS Z SHARES) WHICH ALLOWS YOU TO CHOOSE THE MOST

</TABLE>
 
  The four classes of shares represent an interest in the same portfolio of
investments of the Series and have the same rights, except that (i) each class
is subject to different sales charges and distribution and/or service fees (with
the exception of Class Z shares, which are not subject to any distribution 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
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, and (iii) only Class B shares have a conversion feature. The
four classes also have separate exchange privileges. 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 the Class A and Class Z shares.
 
  Financial advisers and other sales agents who sell shares of the Series will
receive different compensation for selling Class A, Class B, Class C and Class Z
shares and will generally receive more compensation initially for selling Class
A and Class B shares than for selling Class C or Class Z 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).
 
                                       25
<PAGE>
  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 Series:
 
  If you intend to hold your investment in the Series 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 in the case of Class C shares for the higher cumulative annual
distribution-related fee on those shares to exceed the initial sales charge plus
cumulative annual distribution-related fee 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 when 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
UNLESS THE PURCHASER IS ELIGIBLE TO PURCHASE CLASS Z SHARES. See "Reduction and
Waiver of Initial Sales Charges" and "Class Z Shares" 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 of 1933.
 
  In connection with the sale of Class A shares at NAV (without payment of an
initial sales charge), the Manager, the Distributor or one of their affiliates
will pay dealers, financial advisers and other persons which distribute shares a
finders' fee based on a percentage of the net asset value of shares sold by such
persons.
 
  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
 
                                       26
<PAGE>
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 PIFM and their
subsidiaries and members of the families of such persons who maintain an
"employee related" account at Prudential Securities or the Transfer Agent, (c)
employees of Subadvisers of the Prudential Mutual Funds provided that the
purchases at NAV are permitted by such person's employer, (d) Prudential
employees and special agents of Prudential and its subsidiaries and all persons
who have retired directly from active service with Prudential or one of its
subsidiaries, (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 purchase.
 
  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
acquired 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 advisers and other persons who sell 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
sales commissions from the combination of the CDSC and the distribution fee. See
"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.
 
  CLASS Z SHARES
 
  Class Z shares of the Series are available for purchase by the following
categories of investors:
 
  (i) pension, profit-sharing or other employee benefit plans qualified under
Section 401 of the Internal Revenue Code, deferred compensation plans and
annuity plans under Sections 457 and 403(b)(7) of the Internal Revenue Code, and
non-qualified plans for which the Series is an available option (collectively,
Benefit Plans), provided that such Benefit Plans (in combination with other
plans sponsored by the same employer or group of related employers) have at
least $50 million in defined contribution assets; (ii) participants in any
fee-based program or trust program sponsored by Prudential Securities, The
Prudential Savings Bank, F.S.B. (or any affiliate) which includes mutual funds
as investment options and for which the Series is an available option; (iii)
certain participants in the MEDLEY Program (group variable annuity contracts)
sponsored by Prudential for whom Class Z
 
                                       27
<PAGE>
shares are an available investment option; (iv) Benefit Plans for which
Prudential Retirement Services serves as record keeper and, as of September 20,
1996, (a) were Class Z shareholders of the Prudential Mutual Funds, or (b)
executed a letter of intent to purchase Class Z shares of the Prudential Mutual
Funds; (v) current and former Directors/Trustees of the Prudential Mutual Funds
(including the Fund); and (vi) employees of Prudential and/or Prudential
Securities who participate in a Prudential-sponsored employee saving plan.
 
  In connection with the sale of Class Z shares, the Manager, the Distributor or
one of their affiliates may pay dealers, financial advisers and other persons
which distribute shares a finders' fee based on a percentage of the net asset
value of shares sold by such persons.
 
HOW TO SELL YOUR SHARES
 
  YOU CAN REDEEM YOUR SHARES OF THE SERIES 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 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 SERIES THROUGH PRUDENTIAL SECURITIES, YOU MUST
REDEEM YOUR SHARES THROUGH PRUDENTIAL SECURITIES. PLEASE CONTACT YOUR PRUDENTIAL
SECURITIES FINANCIAL ADVISER. IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A
WRITTEN REQUEST FOR REDEMPTION SIGNED BY YOU EXACTLY AS THE ACCOUNT IS
REGISTERED IS REQUIRED. IF YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN
THE NAME(S) SHOWN ON THE FACE OF THE CERTIFICATES, MUST BE RECEIVED BY THE
TRANSFER AGENT 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 CASHIER'S CHECK.
 
                                       28
<PAGE>
  REDEMPTION IN KIND. If the Trustees determine that it would be detrimental to
the best interests of the remaining shareholders of the Series 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 Series, 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 a
regular redemption. See "How the Fund Values its Shares." If your shares are
redeemed in kind, you would incur transaction costs in converting the assets
into cash. The Fund, however, has elected to be governed by Rule 18f-1 under the
Investment Company Act, under which the Fund is obligated to redeem shares
solely in cash up to the lesser of $250,000 or 1% of the net asset value of the
Series during any 90-day period for any one shareholder.
 
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Trustees
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 charge
will be imposed on any such involuntary redemption.
 
  90-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not previously
exercised the repurchase privilege, you may reinvest any portion or all of the
proceeds of such redemption in shares of the Series at the NAV next determined
after the order is received, which must be within 90 days after the date of the
redemption. Any CDSC paid in connection with such redemption will be credited
(in shares) to your account. If less than a full repurchase is made, the credit
will be on a PRO RATA basis. You must notify the 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 may affect the federal tax treatment of any gain or
loss realized upon redemption. 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 or 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 of the Series to an amount which is lower than
the amount of all payments by you for shares of the Series 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 contingent deferred sales charge 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. See "How
to Exchange Your Shares" below.
 
                                       29

  The following table sets forth the rates of the CDSC applicable to redemptions

  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 Series shares made during the preceding six years
(five years for Class B shares purchased prior to January 22, 1990); then of
amounts representing the cost of shares held beyond the applicable CDSC period;
and finally, of amounts representing the cost of shares held for the longest
period of time within the applicable CDSC period.
 
  For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided to
redeem $500 of your investment. Assuming at the time of the redemption the 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 account, following the death or
disability of the grantor. The waiver is available for total or partial
redemptions of shares owned by a person, either individually or in joint tenancy
(with rights of survivorship), or a trust 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 Trustee of the Fund.
 
  You must notify the Transfer Agent either directly or through Prudential
Securities or Prusec, at the time of redemption, that you are entitled to waiver
of the CDSC 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.
 
  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.
 
                                       30

  SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on certain
redemptions from a Systematic Withdrawal Plan. On an annual basis, up to 12% of
the total dollar amount subject to the CDSC may be redeemed without charge. The
Transfer Agent will calculate the total amount available for this waiver
annually, on the 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.
 
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 Series 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 SERIES, YOU HAVE AN EXCHANGE PRIVILEGE WITH THE OTHER
SERIES OF THE FUND AND CERTAIN OTHER PRUDENTIAL MUTUAL FUNDS (THE EXCHANGE
PRIVILEGE), INCLUDING ONE OR MORE SPECIFIED MONEY MARKET FUNDS, SUBJECT TO THE
MINIMUM INVESTMENT REQUIREMENTS OF SUCH FUNDS. CLASS A, CLASS B, CLASS C AND
CLASS Z SHARES MAY BE EXCHANGED FOR CLASS A, CLASS B, CLASS C AND CLASS Z
SHARES, RESPECTIVELY, OF THE OTHER SERIES OF THE FUND AND 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, Inc. 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, weekdays, except
holidays, between the hours of 8:00 A.M. and 6:00 P.M., New York time. For your
protection and to prevent fraudulent exchanges, your telephone call will be
recorded and you will be asked to provide your personal identification number. A
written confirmation of the exchange transaction will be sent to you. NEITHER
THE FUND NOR ITS AGENTS WILL BE LIABLE FOR ANY LOSS, LIABILITY OR COST WHICH
RESULTS FROM ACTING UPON INSTRUCTIONS REASONABLY BELIEVED TO BE GENUINE UNDER
THE FOREGOING PROCEDURES. All exchanges will be made on the basis of the
relative NAV of the two funds or two Series 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"
above) and for shareholders who qualify to purchase Class Z shares (see
"Alternative Purchase Plan--Class Z Shares" above). Under this exchange
privilege, amounts representing any Class B and Class C shares (which are not
subject to a CDSC) held in such a shareholder's account will be automatically
exchanged for Class A shares for shareholders who qualify to purchase Class A
shares at NAV, on a quarterly basis, unless the shareholder elects otherwise.
Similarly, shareholders who qualify to purchase Class Z shares will have their
Class B and Class C shares which are not subject to a CDSC and their Class A
shares exchanged for Class Z shares on a quarterly basis. Eligibility for this
exchange privilege will be calculated on the business day prior to the date of
the exchange. Amounts representing Class B or Class C shares which are not
subject to a CDSC include the following: (1) amounts representing Class B or
Class C shares acquired pursuant to the automatic reinvestment of dividends and
distributions, (2) amounts representing the increase in the net asset value
above the total amount of payments for the purchase of Class B or
 
                                       32
<PAGE>
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.
 
  Participants in any fee-based program for which the Series is an available
option will have their Class A shares, if any, exchanged for Class Z shares when
they elect to have those assets become a part of the fee-based program. Upon
leaving the program (whether voluntarily or not), such Class Z shares (and, to
the extent provided for in the program, Class Z shares acquired through
participation in the program) will be exchanged for Class A shares at net asset
value. Similarly, participants in PSI's 401(k) Plan for which the Series' Class
Z shares is an available option and who wish to transfer their Class Z shares
out of the PSI 401(k) Plan following separation from service (I.E., voluntary or
involuntary termination of employment or retirement) will have their Class Z
shares exchanged for Class A shares at NAV.
 
  The Fund reserves the right to reject any exchange order including exchanges
(and market timing transactions) which are of the 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.

Prudential Securities financial adviser, Prusec representative or the Transfer
Agent directly.
 
  -SYSTEMATIC WITHDRAWAL PLAN.  A systematic withdrawal plan is available to

                                (INTERMEDIATE SERIES)

                           Supplement Dated August 27, 1998
                           to Prospectus Dated July 1, 1998

     The Trustees of Prudential Municipal Bond Fund (the Fund) have recently 
approved a proposal to exchange the assets and liabilities of the 
Intermediate Series (the Series) of the Fund for shares of Prudential 
National Municipals Fund, Inc. (National Municipals Fund).  Class A and Class 
Z shares of the Series would be exchanged at relative net asset value for 
Class A shares of National Municipals Fund and Class B and Class C shares of 
the Series would be exchanged at relative net asset value for Class B and C 
shares, respectively, of National Municipals Fund.

     The transfer has been approved by the Trustees of the Fund and by the 
Board of Directors of National Municipals Fund and is subject to approval by 
the shareholders of the Series.  It is anticipated that a proxy 
statement/prospectus relating to the transaction will be mailed to the 
Series' shareholders in late October 1998.

     Under the terms of the proposal, shareholders of the Series would become 
shareholders of National Municipals Fund.  No shales charge would be imposed 
on the proposed transfer.  The Fund anticipates obtaining an opinion of its 
counsel that the transaction would be a tax-free reorganization under the 
Internal Revenue Code and therefore no gain or loss for Federal income tax 
purposes would be recognized by shareholders of the Series. 

     EFFECTIVE IMMEDIATELY, THE FUND WILL NO LONGER ACCEPT ORDERS TO PURCHASE 
OR EXCHANGE INTO SHARES OF THE SERIES, EXCEPT FOR PURCHASES BY CERTAIN 
RETIREMENT AND EMPLOYEE PLANS (EXCLUDING IRA ACCOUNTS).  Existing 
shareholders may continue to acquire shares through dividend reinvestment.  
The current exchange privilege of obtaining shares of other Prudential Mutual 
Funds and the current redemption privilege will remain in effect until the 
transaction is consummated.

     National Municipals Funds' investment objective is to seek a high level 
of current income exempt from federal income taxes.

SHAREHOLDER GUIDE

SHAREHOLDER SERVICES

     THE PROTECTOR PROGRAM-OPTIONAL GROUP TERM LIFE INSURANCE.  Prudential 
makes available optional group term life insurance coverage to purchasers of 
shares of certain Prudential Mutual Funds which are held in an eligible 
brokerage account. This insurance protects the value of your mutual fund 
investment for your beneficiaries against market downturns.  The insurance 
benefit is based on the difference at the time of the insured's death between 
the "protected value" and the then current market value of the shares.  This 
coverage is not available in all states and is subject to various 
restrictions and limitations.  For more complete information about this 
program, including charges and expenses, please contact your Prudential 
representative.

     Listed below are the names of the Prudential Mutual Funds and the dates 
of the Prospectuses to which the supplement relates.

                               PRUDENTIAL MUTUAL FUNDS

                          Supplement dated October 21, 1998


NEW PRICING STRUCTURE FOR CLASS C SHARES

     Effective on November 2, 1998, Class C shares of the Prudential Mutual 
Funds will be sold with a 1% initial sales charge and will be subject to a 
contingent deferred sales charge of 1% of the lesser of the amount invested 
or the redemption proceeds if redeemed within 18 months of purchase.  In 
connection with the sale of Class C shares, the Distributor will pay dealers, 
financial advisers and other persons who sell Class C shares a sales 
commission of up to 2% of the purchase price at the time of sale.

     Class C shares issued before November 2, 1998 will no be affected by the 
new pricing structure described above and will continue to be subject to a 
contingent deferred sales charge of 1% on redemptions within one year of 
purchase.

WAIVER OF INITIAL SALES CHARGE - CLASS A SHARES

     The paragraph under "Alternative Purchase Plan - Class A Shares - 
Reduction and Waiver of Initial Sales Charges - Benefit Plans" is amended to 
read in its entirety as follows:

     BENEFIT PLANS.  Class A shares may be purchased at NAV, without payment 
of an initial shales charge, by pension, profit-sharing or other employee 
benefit plans qualified under Section 401 of the Internal Revenue Code, 
deferred compensation and annuity plans under Sections 457 and 403(b)(7) of 
the Internal Revenue Code and non-qualified deferred compensation plans that 
are sponsored by any employer that has a tax qualified benefit plan with 
Prudential (collectively, Benefit Plans), provided that the Benefit Plan has 
existing assets of at least $1 million invested in shares of Prudential 
Mutual Funds (excluding money market funds other than those acquired pursuant 
to the exchange privilege) or 250 eligible employees or participants.  In the 
case of Benefit Plans whose accounts are held directly with the Transfer 
Agent or Prudential Securities and for which the Transfer Agent or Prudential 
Securities does individual account recordkeeping (Direct Account Benefit 
Plans) and Benefit Plans sponsored by Prudential, Prudential Securities or 
its subsidiaries (Prudential Securities or Subsidiary Prototype Benefit 
Plans), Class A shares may be purchased at NAV by participants who are 
repaying loans made from such plans to the participant.

WAIVER OF INITIAL SALES CHARGE - CLASS C SHARES

     BENEFIT PLANS.  Class C shares may be purchased at NAV, without payment 
of an initial sales charge, by Benefit Plans (as defined above).  In the case 
of Benefit Plans whose accounts are held directly with the Transfer Agent or 
Prudential Securities and for which the Transfer Agent or Prudential 
Securities does individual account recordkeeping (Direct Account Benefit 
Plans) and Benefit Plans sponsored by Prudential, Prudential Securities or 
its subsidiaries (Prudential Securities or Subsidiary Prototype Benefit 
Plans), Class C shares may be purchased at NAV by participants who are 
repaying the loans made from such plans to the participants.

     PRUDENTIAL RETIREMENT PLANS.  The initial sales charge will be waived 
with respect to purchase of Class C shares by qualified and non-qualified 
retirement and deferred compensation plans participating in the PruArray Plan 
and other plans for which Prudential provides administrative or recordkeeping 
services.

     INVESTMENTS OF REDEMPTION PROCEEDS FROM OTHER INVESTMENT COMPANIES. 
Investors may purchase Class C shares at NAV, without the initial sales 
charge, with the proceeds from the redemption of shares of any unaffiliated 
registered investment company which were not held through an account with any 
Prudential affiliate.  Such purchases must be made within 60 days of the 
redemption.  Investors eligible for this waiver

SHAREHOLDER GUIDE

     The following replaces information under "Shareholder Guide -- Alternative
Purchase Plan":

     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 Funds.

EQUITY FUNDS

     If you intend to hold your investment in a Fund for less than 4 years 
and do not qualify for a reduced sales charge on class A shares, since Class 
A shares are subject to an initial sales charge of 5% and Class B shares are 
subject to a CDSC of 5% which declines to zero over a 6-year period, you 
should consider purchasing Class C shares over either Class A or Class B 
shares.

     If you intend to hold your investment for longer than 4 years, but less 
than 5 years, and do not qualify a reduced sales charge on Class A shares, 
you should consider purchasing Class B or Class shares over Class A shares.  
This is because the sales charge plus the cumulative annual 
distribution-related fee on Class A shares would exceed those of the Class B 
and Class C shares if you redeem your investment during this time period.  In 
addition, more of your money would be invested initially in the case of Class 
C shares, because of the relatively low initial sales charge, and all of your 
money would be invested initially in the case of Class B shares, which are 
sold at NAV.

     If you intend to hold your investment for longer than 5 years, you 
should consider purchasing Class A shares over either Class B or C shares.  
This is because the maximum sales charge plus the cumulative annual 
distribution-related fee on Class A shares would be less than those of Class 
B and C shares.

     If you qualify for a reduced sales charge on Class A shares, it may be 
more advantageous for you to purchase Class A shares over either Class B or 
Class C shares regardless of how long you intend to hold your investment.  
However, unlike Class B shares, you would not have all of your money invested 
initially because the sales charge on Class A shares is deducted at the time 
of purchase.

     If you do not qualify for a reduced sales charge on Class A shares and 
you purchase Class B or Class C Shares, you would have to hold your 
investment for more than 6 years in the case of Class B shares and for more 
than 5 years in the case of Class C shares for the higher cumulative annual 
distribution-related fee on those shares plus, in the case of Class C shares, 
the 1% initial sales charge to exceed the intitial sales charge plus the 
cumulative annual distribution-related fees on Class A shares.  This does not 
take into account the fee value of money, which further reduces the impact of 
the higher Class B or Class C distribution-related fee of the investment, 
fluctuations in NAV, the effect of the return on the investment over this 
period of time or exemptions when the CDSC is applicable.

TAX-EXEMPT BOND FUNDS

     If you intend to hold your investment in a Fund for less than 3 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 3 years, but less 
than 4 years, or for more than 5 years, but less than 6 years, you should 
consider purchasing Class A shares, because the maximum 3% initial sales 
charge plus the cumulative annual distribution-related fee on Class A shares 
would be lower than: (i) the contingent-deferred sales charge plus the 
cumulative annual distribution-related fee on Class B shares; and (ii) the 3% 
initial sales charge plus the cumulative annual distribution-related fee on 
Class C shares.

value of money, which further reduces the impact of the higher Class B or 
Class C distribution-related fee on the investment, fluctuation in NAV, the 
effect of the return on the investment over this period of time or 
redemptions when the CDSC is applicable.

GOVERNMENT INCOME FUND

     If you intend to hold your investment in the Fund for less than 4 years 
and do not qualify for a reduced sales charge on Class A shares, since Class 
A shares are subject to a maximum initial sales charge of 4% 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 4 years, but less 
than 5 years, you may consider purchasing Class A shares or Class C share 
because: (i) the maximum 4% initial sales charge plus the cumulative annual 
distribution-related fee on Class A shares; and (ii) the maximum 1% initial 
sales charge plus the cumulative annual distribution-related fee on Class C 
shares would be lower than the contingent-deferred sales charge plus the 
cumulative annual distribution-related fee on Class B shares.

     If you intend to hold your investment for longer than 5 years, you 
should consider purchasing Class A shares over either Class  B or Class C 
shares. This is because the maximum sales charge plus the cumulative annual 
distribution-related fee on Class A shares would be less than those of the 
Class B and Class C shares.

     If you qualify for a reduced sales charge on Class A shares, it may be 
more advantageous for you to purchase Class A shares over either Class B or 
Class C shares regardless of how long you intend to hold your investment. 
However, unlike Class B shares, you would not have all of your money invested 
initially because be sales charge on Class A shares is deducted at the time 
of purchase.

     If you do not qualify for a reduced sales charge on Class A shares and 
you purchase Class B or Class C shares, you would have to hold your 
investment for more than 5 years for the higher cumulative annual 
bisolution-related fee on those shares plus, in the case of Class C shares, 
the 1% initial sales charge to exceed the initial sales charge plus 
cumulative annual distribution-related fee on Class A shares. This does not 
take into account the time value of money, which further reduces the impact 
of the higher Class B or Class C distribution-related fee on the investment, 
fluctuations in NAV, the effect of the return on the investment over this 
period of time or redemptions when the CDSC is applicable.

STRUCTURED MATURITY FUND

     If you intend to hold your investment in the Fund for less than 2 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 3.25% and Class B 
shares are subject to a CDSC of 3% which declines to zero over a 4 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 2 years, but less 
than 3 years, you may consider purchasing Class B or Class C shares because: 
(i) the contingent-deferred shales load plus the cumulative annual 
distribution-related fee on Class B shares: and (ii) the maximum 1% initial 
sales charge plus the cumulative annual distribution-related fee on Class C 
shares would be lower than the maximum 3.25% initial sales charge plus the 
cumulative annual distribution-related fee on Class A shares. In addition, 
more of your money would be invested initially in the case of Class C shares, 
because of the relatively low initial sales charge, and all of your money 
would be invested initially in the case of Class B shares, which are sold at 
NAV.

     If you intend to hold your investment for more than 3 years, but less 
than 4 years, you may consider purchasing Class A shares because the maximum 
3.25% initial sales charge plus the cumulative annual distribution-related 
fee on Class A shares would be lower than: (i) the contingent-deferred sales 
charge plus

<PAGE>

would be less than the maximum 1% initial sales charge plus the cumulative 
annual distribution-related fee on Class C shares.

     If you intend to hold your investment for longer than 5 years, you 
should consider purchasing Class A shares over either Class B or Class C 
shares. This is because the maximum sales charge plus the cumulative annual 
distribution-related fee on Class A shares would be less than the cumulative 
annual distribution-related fee on Class B shares and less than the initial 
sales charge plus the cumulative annual distribution-related fee on 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 you investment. 
However, unlike Class B shares, you would not have all of your money invested 
initially because the sales charge on Class A shares is deducted at the time 
of purchase.

     If you do not qualify for a reduced sales charge on Class A shares and 
you purchase Class C shares, you would have to hold your investment for more 
than 3 years for the higher cumulative annual distribution-related fee on the 
Class C shares plus the 1% initial sales charge to exceed the initial sales 
charge plus cumulative annual distribution-related fee 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 NAV, the effect of the return on the investment 
over this period of time or redemptions when the CDSC is applicable.

PRUDENTIAL MUNICIPAL SERIES FUND/MARYLAND AND MICHIGAN SERIES
PRUDENTIAL MUNICIPAL BOND FUND/INTERMEDIATE SERIES
 
November 25, 1998

 
Dear Shareholder:
 
You may be aware that the Trustees of Prudential Municipal Series Fund/Maryland
Series and Michigan Series and the Trustees of Prudential Municipal Bond
Fund/Intermediate Series have recently approved a proposal to exchange the
assets and liabilities of your Series for shares of Prudential National
Municipals Fund. The enclosed proxy materials describe this proposal in detail.
If the proposal is approved by the shareholders and implemented, you will
automatically receive shares of Prudential National Municipals Fund in exchange
for your share of each Series.
 
THE TRUSTEES AND I STRONGLY RECOMMEND THAT YOU VOTE FOR THE PROPOSAL. WE BELIEVE
THAT THIS TRANSACTION SERVES YOUR INTERESTS IN THE FOLLOWING WAYS:
 
SIMILAR STRATEGIES--GREATER FLEXIBILITY
 
     The Funds' investment objectives and strategies, while not identical, are
     similar. Each invests primarily in investment grade, tax-exempt municipal
     bonds. While Maryland and Michigan Series seek to provide income exempt
     from federal and Maryland and Michigan state income taxes, respectively,
     Prudential National Municipals Fund seeks income exempt from only federal
     income taxes. Increasingly, single state series have had difficulty finding
     attractive issues due to a shrinking municipal bond supply--making
     portfolio diversification a challenge. In contrast, Prudential National
     Municipals Fund is nationally diversified, enabling it to invest in a wider
     range of municipal bond investment opportunities.
 
EXPENSE LEVELS
 
     The Series have relatively few assets and have not been able to attract new
     assets. They operated with relatively high expense ratios before voluntary
     management fee waivers, which were discontinued by the Manager as of
     September 1, 1997.
 
POTENTIAL FOR HIGHER INCOME GENERALLY EXEMPT INCOME TAXES
 
     The municipal obligations held by National Municipals Fund have
     historically had a higher gross yield than the obligations in the Series'
     portfolios and National Municipals Fund has lower expense ratios than the
     Series due to its appreciably larger size.
 

PRUDENTIAL NATIONAL MUNICIPALS FUND'S investment objective is to seek a high
level of current income exempt from federal income taxes. The Fund seeks to
achieve this objective by investing in a broadly diversified portfolio of
municipal bonds issued from across the country. Portfolio manager Peter
Allegrini has over 19 years of investment experience.
