PRUDENTIAL MUNICIPAL SERIES FUND/MARYLAND AND MICHIGAN SERIES
PRUDENTIAL MUNICIPAL BOND FUND/INTERMEDIATE SERIES
    
 
   
October  , 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 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.

             PROSPECTUS AND PROXY STATEMENT DATED OCTOBER   , 1998

                                    SYNOPSIS
 
   
    The  following  synopsis  is  a  summary  of  certain  information contained
elsewhere in this Prospectus and Proxy Statement and the Agreements and Plans of
Reorganization (with respect to  each of the Maryland  and Michigan Series,  the
State  Series Plan;  with respect to  the Intermediate  Series, the Intermediate
Series Plan, and collectively, the Plans)  and is qualified by reference to  the
more complete information contained herein as well as in the Prospectuses of the
Maryland   Series  and  Michigan  Series  (collectively  the  State  Series)  of
Prudential  Municipal  Series   Fund  (Series  Fund)   and  the  Prospectus   of
Intermediate  Series (Intermediate  Series, collectively with  the State Series,
the Series) of the Prudential Municipal Bond Fund (Municipal Bond Fund) and  the
enclosed  Prospectus  of  Prudential National  Municipals  Fund,  Inc. (National
Municipals Fund, and together with the Series Fund and Municipal Bond Fund,  the
Funds).  Shareholders  should read  the  entire Prospectus  and  Proxy Statement
carefully.
    
 
   
GENERAL
    
 
   
    This Prospectus and  Proxy Statement  is furnished  by the  Trustees of  the
Series  Fund  and Municipal  Bond Fund  in connection  with the  solicitation of
Proxies for use at a  Special Meeting of Shareholders of  each of the Series  of
such  Funds (the Meeting)  to be held  at 9:00 A.M.  on December 3,  1998 at the
Prudential Insurance  Company  of America,  Plaza  Building, 751  Broad  Street,
Newark,  New Jersey 07102.  The purpose of  the Meeting is  to approve each Plan
whereby all of the assets of the respective Series will be acquired by, and  the
liabilities of each Series, if any, will be assumed by National Municipals Fund,
in  exchange for shares  of common stock  of National Municipals  Fund, and such
other business  as may  properly  come before  the  Meeting or  any  adjournment
thereof.  The  Plans are  attached  to this  Prospectus  and Proxy  Statement as
Appendix B.
    
 
   
    Approval of  the Plans  with respect  to a  particular Series  requires  the
affirmative vote of a majority of the shares of that Series that are outstanding
and  entitled to  vote. Shareholders  of each  Series vote  together and  not by
separate class within each Series. Approval of the Plans by the shareholders  of
National  Municipals Fund is not required and  the Plans are not being submitted
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  and Class C
shares of National Municipals Fund will be  distributed to Class A, Class B  and
Class  C shareholders, respectively, of Intermediate  Series; and Class A shares
of National  Municipals Fund  will be  distributed to  Class Z  shareholders  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 and
Class C shares of  National Municipals Fund  and Class A, Class  B, and Class  C
shares  of each Series and, with respect  to Intermediate Series, Class Z shares
were as follows:

    respect to both National Municipal Fund and the Series.

     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 and Intermediate 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  and Class C  shares of the
Series currently are subject to maximum deferred sales loads of up to 5% and 1%,
respectively. If the State  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.

<PAGE>
   
    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 and Class  Z
shareholder  of  Intermediate  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. Each  Class B and Class  C shareholder of Intermediate  Series
will  receive the  number of  full and  fractional Class  B and  Class C shares,
respectively, 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. Furthermore, 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 deferred sales  loads
with  respect  to  Class B  and  Class  C shares  of  National  Municipals Fund,
respectively.  Therefore,  Class  A,  Class  B  and  Class  C  shareholders   of
Intermediate  Series will not be subject  to any additional distribution fees or
sales loads  following  the Reorganization.  Although  Class Z  shareholders  of
Intermediate  Series  will  be  subject to  a  maximum  distribution  fee (after
reduction) of  .10  of  1% with  respect  to  the Class  A  shares  of  National
Municipals Fund to be received in the Reorganization, it is anticipated that the
Total  Fund Operating Expenses (after reduction)  with respect to Class A shares
of National  Municipals Fund  following the  Reorganization will  be lower  than
Total  Fund Operating  Expenses with respect  to Class Z  shares of Intermediate
Series prior to the  Reorganization. See "Fees  and Expenses--Pro Forma  Expense
Ratios--Annual Fund Operating Expenses (as a percentage of average net assets)."
    
 
   
    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 30
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 750  million shares of common  stock, $.01 par value  per
share.  The State  Series and National  Municipals Fund 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. Intermediate Series
has divided its shares into four classes,  designated Class A, Class B, Class  C
and  Class Z, each of  which is currently being  offered by Municipal Bond Fund.
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
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 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 received
an order  from the  Commission  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 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. 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
    
 
                                       8
<PAGE>
   
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."
    
 
FEES AND EXPENSES
 
   
    MANAGEMENT  FEES.    PIFM,  the  Manager  of  each  Fund  and  an  indirect,
wholly-owned  subsidiary  of  The   Prudential  Insurance  Company  of   America
(Prudential),  is compensated, pursuant to  a management agreement with National
Municipals Fund, at an annual rate of .50 of 1% of the first $250 million of the
average daily net assets  of National Municipals  Fund, .475 of  1% of the  next
$250 million of the average daily net assets of National Municipals Fund, .45 of
1%  of the  next $500  million of National  Municipals Fund's  average daily net
assets, .425  of 1%  of the  next  $250 million  of National  Municipals  Fund's
average  daily  net assets,  .40  of 1%  of the  next  $250 million  of National
Municipals Fund's average daily net assets and  .375 of 1% of the average  daily
net  assets of National Municipals Fund in excess of $1.5 billion. Pursuant to a
management agreement with Series Fund, PIFM is compensated at an annual rate  of
 .50  of 1%  of the  average daily net  assets of  each of  Maryland and Michigan
Series. Pursuant to  a management agreement  with Municipal Bond  Fund, PIFM  is
compensated  at an annual rate of  .50 of 1% of the  average daily net assets of
Intermediate Series up  to $1 billion  and .45 of  1% of the  average daily  net
assets of Intermediate Series in excess of $1 billion.
    
 
   
    For  the fiscal year ended December  31, 1997, National Municipals Fund paid
PIFM management fees  of .48% of  National Municipals Fund's  average daily  net
assets.  For the fiscal year ended August 31, 1998, Maryland and Michigan Series
paid PIFM management fees at  an annual rate of .50  of 1% of its average  daily
net  assets. For the fiscal year ended  April 30, 1998, Municipal Bond Fund paid
PIFM management  fees  of  .48%  of  average  daily  net  assets  on  behalf  of
Intermediate  Series. PIFM discontinued  its management fee waiver  of .05 of 1%
with respect to  National Municipals  Fund and each  Series as  of September  1,
1997.
    
 
    Under  subadvisory  agreements between  PIFM  and The  Prudential Investment
Corporation, doing business  as Prudential Investments  (PI or the  Subadviser),
the  Subadviser provides investment advisory services  for the management of the
respective  Funds.   Each  subadvisory   agreement  provides   that  PIFM   will
 
                                       9
<PAGE>
   
reimburse  PI  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 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
the  Distribution  Agreement  with  Municipal Series  Fund,  none  of  which are
reimbursed by or  paid for by  Municipal Bond Fund.  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.

                                       10

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.
    
 
   
    SHAREHOLDER TRANSACTION EXPENSES.   The  following table  provides the  fees
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 the Series
and  Class  Z  shares  of  Intermediate  Series.  However,  if  the  Plans   are
implemented,  Class A, Class B and Class  C shareholders of the State Series and
Class A and  Class Z shareholders  of Intermediate 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.

    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.  After 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. 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    %,    % and    % for Maryland  Series
and     %,     % and     % 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.  After 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.

    PRO  FORMA EXPENSE RATIOS.  Following the reorganization, 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'
operating expenses for, 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

+   Although the Class A and Class C Distribution and Service Plans provide that
    each Fund may pay a distribution fee of up to .30 of 1% and 1% per annum  of
    the   average  daily  net  assets  of  the  Class  A  and  Class  C  shares,
    respectively, the Distributor has limited its distribution fees with respect
    to the Class A and Class C shares of each Fund to no more than .10 of 1% and
    .75 of 1% of  the average daily net  asset value of the  Class A shares  and
    Class  C shares, respectively. Total Fund  Operating Expenses of the Class A
    and Class  C shares  without  such limitations  would  be 1.37%  and  2.07%,
    respectively,  for  Maryland  Series,  1.16%  and  1.86%,  respectively, for
    Michigan Series,  1.53% and  2.23%, respectively,  for Intermediate  Series,
    0.93%  and 1.63%, respectively, for National  Municipals Fund, and 0.92% and

THE  EXAMPLE  SHOULD  NOT  BE  CONSIDERED A  REPRESENTATION  OF  PAST  OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
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) or (ii) on a deferred  basis
(Class B or 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 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 without an initial sales charge
and, for one year 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 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 and  Class A  and Class  Z shareholders of
Intermediate 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, Class C and Class Z
shares as  of  the  closing date.  The  Class  B and  Class  C  shareholders  of
Intermediate  Series will receive the number of  full and fractional Class B and
Class C shares 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
    
 
                                       13
<PAGE>
   
CHARGES WILL BE  IMPOSED IN  CONNECTION WITH THE  REORGANIZATION. FOLLOWING  THE
REORGANIZATION,  SHAREHOLDERS HOLDING CLASS A 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  and  Class  C
shareholders   of  National  Municipals  Fund  are  identical  to  the  exchange
privileges of Class A, Class B  and Class C shareholders, respectively, of  each
Series.  National Municipals Fund does not offer Class Z shares. 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 and Class C shares of  each Fund may be exchanged for Class A,
Class B  and Class  C 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 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."

<PAGE>
                             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 (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
may  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
    
 
                                       15
<PAGE>
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.
    
 
   
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
    
 
                                       16
<PAGE>
   
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 4, 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.
    
 
   
    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 4,
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 and Class C shares of National Municipals Fund
to the Class A, Class B and  Class C shareholders of Intermediate Series and  of
Class  A  shares of  National Municipals  Fund  to the  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 each Series Class A shares of National
    
 
                                       17
<PAGE>
   
Municipals Fund, which the Maryland and Michigan Series will then distribute  to
their  Class A, Class B and Class C shareholders, respectively, and Intermediate
Series  will  then  distribute  to  its  Class  A  and  Class  Z   shareholders,
respectively.   National   Municipals  Fund   will  simultaneously   deliver  to
Intermediate Series Class B and Class C shares of National Municipals Fund which
Intermediate  Series  will  then  distribute  to   its  Class  B  and  Class   C
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 and  Class A and  Class Z  shares of Intermediate  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 or, in the  case of Intermediate Series, the value
of that  shareholder's Class  A or  Class Z  shares. Each  Class B  and Class  C
shareholder  of the  Intermediate Series  will own Class  B and  Class C 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 B  or Class  C 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  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;
    
 
   
        (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
    
 
                                       19
<PAGE>
   
        (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 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
    
 
                                       20
<PAGE>
   
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 750 million  shares of common stock divided into  three
classes,  consisting  of  250 million  authorized  Class A  shares,  250 million
authorized Class B shares and 250 million authorized Class C 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. The State Series currently offer Class  A,
Class  B and Class C shares. Intermediate Series currently offers Class A, Class
B, Class C and  Class Z 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
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
    
 
                                       21
<PAGE>
   
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 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.
 
                                       22
<PAGE>
   
    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 October 15, 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 [    ] Class A shares, [    ]
Class B shares  and [      ] Class C  shares outstanding and  entitled to  vote;
Michigan  Series had [       ] Class A, [       ]  Class B and [       ] Class C
shares outstanding and entitled to vote;  and Intermediate Series had [        ]
Class  A, [        ] Class B,  [        ] Class C and  [        ] 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 October 30, 1998.

    As  of October 15,  1998, the Directors and  officers of National Municipals
Fund, as a group, owned less than 1% of the outstanding shares of such Fund.
    
 
   
    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 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.

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.

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.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
    Agreement and Plan of Reorganization (Agreement) made as of the     day of
October, 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 are divided into three classes, designated Class A, Class B and Class C.
Shares of 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 and Class C 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 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, Class B and Class C
shares of Common Stock (computed in the manner and as of the time and date set
forth in paragraph 2.2); to issue and deliver to Intermediate Series in exchange
therefor the number of shares of Class A shares of Common Stock in National
Municipals Fund determined by dividing the net asset value of the Intermediate
Series allocable to 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 shares of Common
Stock (computed in the manner and as of the time and date set forth in paragraph
2.2), and (c) 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).
    
 
                                     B-1(A)
<PAGE>
   
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 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 and Class C
shareholders of record, determined as of the close of business on the Closing
Date, the Class A, Class B and Class C shares of National Municipals Fund and to
its Class Z shareholders of record, determined as of the close of business on
the Closing Date. The 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 and Class C 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 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
    
 
                                     B-2(A)
<PAGE>
   
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.
    
 
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

    7.5.1  Municipal Bond Fund is duly organized and validly existing under the
    laws of the Commonwealth of Massachusetts with power under its Declaration
    of Trust to own all of its properties and assets and, to the knowledge of
    such counsel, to carry on its business as presently conducted and
    Intermediate Series has been duly established in accordance with the terms
    of the Municipal Bond Fund's Declaration of Trust as a separate series of
    Municipal Bond Fund;
    
 
   
    7.5.2  This Agreement has been duly authorized, executed and delivered by
    Municipal Bond Fund and constitutes a valid and legally binding obligation
    of Municipal Bond Fund enforceable against the assets of Intermediate Series
    in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
    transfer, reorganization, moratorium and similar laws of general
    applicability relating to or affecting creditors' rights and to general
    equity principles;
    
 
   
    7.5.3  The execution and delivery of the Agreement did not, and the
    performance by Municipal Bond Fund of its obligations hereunder will not,
    (i) violate Municipal Bond Fund's Declaration of Trust or By-Laws or (ii)
    result in a default or a breach of (a) the Management Agreement, dated June
    1, 1995, between Municipal Bond Fund and Prudential Investments Fund
    Management LLC, as successor to Prudential Mutual Fund Management, Inc., (b)
    the Custodian Contract, dated August 25, 1987, between Municipal Bond Fund

    that such counsel may state that insofar as performance by Municipal Bond
    Fund of its obligations under this Agreement is concerned they express no
    opinion as to bankruptcy, insolvency, fraudulent transfer, reorganization,
    moratorium and similar laws of general applicability relating to or
    affecting creditors' rights and to general equity principles;
    
 
   
    7.5.4  All regulatory consents, authorizations and approvals required to be
    obtained by Municipal Bond Fund under the federal laws of the United States

    the transactions contemplated by this Agreement have been obtained;
    
 
                                    B-11(A)

    instituted or threatened against Series Fund, involving Intermediate Series,

    N-1A and is not so disclosed; and
    
 
   
    7.5.6  Municipal Bond Fund has been registered with the SEC as an investment
    company, and, to the knowledge of such counsel, no order has been issued or
    proceeding instituted to suspend such registration.

it addresses Massachusetts law, and may assume for purposes of the opinion given
pursuant to paragraph 7.5.2 that New York law is the same as Illinois law.

                     AGREEMENT AND PLAN OF REORGANIZATIONS
    
 
   
    Agreement  and Plan of Reorganizations (Agreement) made as  of the    day of
October,  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  both Funds 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                ,  1998 or such later date as  the

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

    7.5.2  This Agreement  has been duly authorized,  executed and delivered  by
    Series Fund and constitutes a valid and legally binding obligation of Series
    Fund  enforceable against the  assets of each Series  in accordance with its
    terms,   subject   to    bankruptcy,   insolvency,   fraudulent    transfer,
    reorganization,   moratorium  and  similar  laws  of  general  applicability
    relating to or affecting creditors' rights and to general equity principles;
 
   
    7.5.3   The  execution  and delivery  of  the  Agreement did  not,  and  the
    performance  by  Series  Fund of  its  obligations hereunder  will  not, (i)
    violate Series Fund's Declaration  of Trust or By-Laws  or (ii) result in  a
    default  or a  breach of  (a) the  Management Agreement,  dated December 30,
    1988, between Series Fund and Prudential Investments Fund Management LLC, as
    successor to  Prudential Mutual  Fund Management,  Inc., (b)  the  Custodian
    Contract,  dated August 1,  1990, between Series Fund  and State Street Bank
    and Trust  Company,  (c) the  Distribution  Agreement dated  June  1,  1998,
    between  Series Fund and  Prudential Investment Management  Services LLC and
    the Transfer Agency and  Service Agreement, dated  January 1, 1988,  between
    Series  Fund  and  Prudential  Mutual Fund  Services  LLC,  as  successor to
    Prudential Mutual Fund Services, Inc.; provided, however, that such  counsel
    may  state that  insofar as  performance by  Series Fund  of its obligations
    under this Agreement is concerned they express no opinion as to  bankruptcy,
    insolvency, fraudulent transfer, reorganization, moratorium and similar laws
    of  general applicability relating to or  affecting creditors' rights and to
    general equity principles;
    
 
    7.5.4  All regulatory consents, authorizations and approvals required to  be
    obtained  by Series Fund under the federal laws of the United States and the
    laws of  The  Commonwealth of  Massachusetts  for the  consummation  of  the
    transactions contemplated by this Agreement have been obtained;
 
    7.5.5   Such counsel  knows of no litigation  or any governmental proceeding
    instituted or threatened  against Series  Fund, involving  any Series,  that
    would be required to be disclosed in its Registration Statement on Form N-1A
    and is not so disclosed; and
 
    7.5.6    Series Fund  has  been registered  with  the SEC  as  an investment
    company, and, to the knowledge of such counsel, no order has been issued  or
    proceeding instituted to suspend such registration.
 
    Such  opinion may rely on an opinion  of Massachusetts counsel to the extent
it addresses Massachusetts law, and may assume for purposes of the opinion given
pursuant to paragraph 7.5.2 that New York law is the same as Illinois law.

    include the holding period thereof when held by such Series;
    
 
   
    8.6.6  The Series shareholders' bases for the shares of National  Municipals

                              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
 
<PAGE> 
 
  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 
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. The fee is computed daily and payable monthly. The Management 
Agreement also provides that, in the event the expenses of the Fund (including 
the fees of PIFM, but excluding interest, taxes, brokerage commissions, 
distribution fees and litigation and indemnification expenses and other 
extraordinary expenses not incurred in the ordinary course of the Fund's 
business) for any fiscal year exceed the lowest applicable annual expense 
limitation established and enforced pursuant to the statutes or regulations of 
any jurisdiction in which the Fund's shares are qualified for offer and sale, 
the compensation due 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.

  For the fiscal years ended December 31, 1997, 1996 and 1995, the Fund paid 
PIFM management fees of $2,869,410 (net of waiver of $215,979), $2,996,081 (net 
of waiver of $351,073) and $2,983,142 (net of waiver of $349,455), 
respectively. 
 
  PIFM has entered into the Subadvisory Agreement with PI (the Subadviser), a 
wholly-owned subsidiary of Prudential. The Subadvisory Agreement provides that 
the Subadviser will furnish investment advisory services in connection with the 
management of the Fund. In connection therewith, the Subadviser is obligated to 
keep certain books and records of the Fund. PIFM continues to have 
responsibility for all investment advisory services pursuant to the Management 
Agreement and supervises the Subadviser's performance of such services. The 
Subadviser is reimbursed by PIFM for the reasonable costs and expenses incurred 
by the Subadviser in furnishing those services. Investment advisory services 
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.

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 
Shares-Contingent Deferred Sales Charges" in the Prospectus. 
 
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

  (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.

  The Transfer Agent reserves the right to request such additional documents as

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. 
                                      B-17
 
<PAGE> 
 
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. 
                                      B-18
 
<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
 
<PAGE> 
 
  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. 
 
  From time to time, the performance of the Fund may be measured against 
various indices. Set forth below is a chart which compares the performance of 
different types of investments over the long-term and the rate of inflation.1

                      CUSTODIAN AND TRANSFER AND DIVIDEND
                  DISBURSING AGENT AND INDEPENDENT ACCOUNTANTS
 
  State Street Bank and Trust Company, 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. 
 
  Prudential Mutual Fund Services LLC (PMFS), Raritan Plaza One, Edison, New 
Jersey 08837, serves as the Transfer and Dividend Disbursing Agent of the Fund. 
It is a wholly-owned subsidiary of PIFM. PMFS provides customary transfer

                   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

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.

  substantially all of the Prudential Mutual Funds. Wellington Management 
  Company serves as the subadviser to Global Utility Fund, Inc., 
  Nicholas-Applegate Capital Management as subadviser to Nicholas-Applegate 
  Fund, Inc., Jennison Associates Capital Corp. as the subadviser to Prudential 
  Jennison Series Fund, Inc. and Mercater Asset Management, L.P., as subadviser

  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

Information about Prudential Securities
 
  Prudential Securities is the fifth largest retail brokerage firm in the 
United States with approximately 5,600 financial advisors. It offers to its 
clients a wide range of products, including Prudential Mutual Funds and 
annuities. As of December 31, 1995, assets held by Prudential Securities for

Certified Financial Planner (CFP) program. In the December 1995 issue of 
Registered Rep, an industry publication, Prudential Securities' Financial 
Advisor training programs received a grade of A(compared to an industry average 
of B+) . 
 
  In 1995, Prudential Securities' equity research team ranked 8th in 
Institutional Investor magazine's 1995 "All America Research Team" survey. Five 
Prudential Securities' analysts were ranked as first-team finishers.8 
 
  In addition to training, Prudential Securities provides its financial 
advisors with access to firm economists and market analysts. It has also 
developed proprietary tools for use by financial advisors, including the 
Financial ArchitectSM, a state-of-the-art asset allocation software program 
which helps Financial Advisors to evaluate a client's objectives and overall 
financial plan, and a comprehensive mutual fund information and analysis system 
that compares different mutual funds.

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.

Notes to Financial Statements
(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.

- --------------------------------------------------------------------------------
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

- --------------------------------------------------------------------------------
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
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. During the year ended April 30, 1998, the
Fund incurred fees of approximately $609,100 ($361,000-High Yield Series;
$221,700-Insured Series; $26,400-Intermediate Series) for the services of PMFS.
As of April 30, 1998, approximately $51,600 ($31,100-High Yield Series;
$18,300-Insured Series; $2,200-Intermediate Series) of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations also
include certain out of pocket expenses paid to nonaffiliates.

ended April 30, 1998, as having been incurred in the following year.
- ------------------------------------------------------------
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.

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.

                      AGREEMENT AND PLAN OF REORGANIZATION
 

    Agreement and Plan of Reorganization (Agreement) made as of the     day of
October, 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 are divided into three classes, designated Class A, Class B and Class C.
Shares of 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 and Class C 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 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, Class B and Class C
shares of Common Stock (computed in the manner and as of the time and date set
forth in paragraph 2.2); to issue and deliver to Intermediate Series in exchange
therefor the number of shares of Class A shares of Common Stock in National
Municipals Fund determined by dividing the net asset value of the Intermediate
Series allocable to 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 shares of Common
Stock (computed in the manner and as of the time and date set forth in paragraph
2.2), and (c) 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
<PAGE>

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 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 and Class C
shareholders of record, determined as of the close of business on the Closing
Date, the Class A, Class B and Class C shares of National Municipals Fund and to
its Class Z shareholders of record, determined as of the close of business on
the Closing Date. The 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 and Class C 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 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

 
                                     2
<PAGE>

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.

 
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 4, 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

 
                                     3
<PAGE>

(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 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.

                     AGREEMENT AND PLAN OF REORGANIZATIONS

 

    Agreement  and Plan of Reorganizations (Agreement) made as  of the    day of
October,  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  both Funds 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.
 
                                     16
<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.
 
                                     17
<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                ,  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.
 
                                     18
<PAGE>

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

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.

    8.6.3  No gain or loss will be recognized to any Series upon the transfer of
    its assets to  National Municipals  Fund solely  in exchange  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 such Series' shareholders in complete termination of such Series;
 
    8.6.4   No gain or loss will  be recognized to National Municipals Fund upon
    the acquisition  of any  Series' assets  solely in  exchange for  shares  of
    National  Municipals Fund and the assumption of such Series' liabilities, if
    any;

    holding  period of  such assets  acquired by  National Municipals  Fund will
    include the holding period thereof when held by such Series;

    8.6.7  The holding period of National Municipals Fund shares to be  received
    by each Series' shareholders will include the period during which the shares

                                  DEALER AGREEMENT
                                          
                   PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC


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

     1.   LICENSING

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

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

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

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

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

     2.   ORDERS

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


                                        1

<PAGE>

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

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

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

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

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


     3.   DUTIES OF DEALER

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

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

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


                                        2

<PAGE>

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

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

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

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

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


                                        3

<PAGE>

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

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

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

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

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

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

     4.   DEALER COMPENSATION

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


                                        4

<PAGE>

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

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

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

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

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


                                        5

<PAGE>

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

     5.   REDEMPTIONS, REPURCHASES AND EXCHANGES

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

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

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

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

     6.   MULTIPLE CLASSES OF SHARES 

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

     7.   FUND INFORMATION

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


                                        6

<PAGE>

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

     8.   SHARES

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

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

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

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

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


                                        7

<PAGE>

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

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

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

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

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

     10.  TERMINATION; AMENDMENT

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

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

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


                                        8

<PAGE>

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

          d.   This Agreement is not assignable or transferable and will
terminate automatically in the event of its "assignment," as defined in the
Investment Company Act of 1940, as amended and the rules, regulations and
interpretations thereunder.  The Distributor may, however, transfer any of its
duties under this Agreement to any entity that controls or is under common
control with Distributor. 
          
          e.   This Agreement may be amended by Distributor at any time by
written notice to Dealer.  Dealer's placing of an order or accepting payment of
any kind after the effective date and receipt of notice of such amendment shall
constitute Dealer's acceptance of such amendment.

                                ----------------------

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

                                      WITNESSETH

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

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

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

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

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

          NOW, THEREFORE, the parties agree as follows:

Section 1.  APPOINTMENT OF THE DISTRIBUTOR

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

<PAGE>

Section 2.  EXCLUSIVE NATURE OF DUTIES

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

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

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

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

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

Section 3.  PURCHASE OF SHARES FROM THE FUND

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

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

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


                                          2
<PAGE>

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

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

Section 4.  REPURCHASE OR REDEMPTION OF SHARES BY THE FUND

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

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

          4.3  Redemption of any class and/or series of Shares or payment may be
suspended at times when the New York Stock Exchange is closed for other than
customary weekends and holidays, when trading on said Exchange is restricted,
when an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, or during any
other period when the Securities and Exchange Commission, by order, so permits.


                                          3
<PAGE>

Section 5.  DUTIES OF THE FUND

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

          5.2  The Fund shall furnish the Distributor copies of all information,
financial statements and other papers which the Distributor may reasonably
request for use in connection with the distribution of Shares, and this shall
include one certified copy, upon request by the Distributor, of all financial
statements prepared for the Fund by independent public accountants.  The Fund
shall make available to the Distributor such number of copies of its Prospectus
and annual and interim reports as the Distributor shall reasonably request.

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

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


                                          4
<PAGE>

Section 6.  DUTIES OF THE DISTRIBUTOR

          6.1  The Distributor shall devote reasonable time and effort to effect
sales of Shares, but shall not be obligated to sell any specific number of
Shares.  Sales of the Shares shall be on the terms described in the Prospectus.
The Distributor may enter into like arrangements with other investment
companies.  The Distributor shall compensate the selected dealers as set forth
in the Prospectus.

          6.2  In selling the Shares, the Distributor shall use its best efforts
in all respects duly to conform with the requirements of all federal and state
laws relating to the sale of such securities.  Neither the Distributor nor any
selected dealer nor any other person is authorized by the Fund to give any
information or to make any representations, other than those contained in the
Registration Statement or Prospectus and any sales literature approved by
appropriate officers of the Fund.

          6.3  The Distributor shall adopt and follow procedures for the
confirmation of sales to investors and selected dealers, the collection of
amounts payable by investors and selected dealers on such sales and the
cancellation of unsettled transactions, as may be necessary to comply with the
requirements of Securities Exchange Act Rule 10b-10 and the rules of the
National Association of Securities Dealers, Inc. (NASD).

          6.4  The Distributor shall have the right to enter into selected
dealer agreements with registered and qualified securities dealers and other
financial institutions of its choice for the sale of Shares, provided that the
Fund shall approve the forms of such agreements.  Within the United States, the
Distributor shall offer and sell Shares only to such selected dealers as are
members in good standing of the NASD or are institutions exempt from
registration under applicable federal securities laws.  Shares sold to selected
dealers shall be for resale by such dealers only at the offering price
determined as set forth in the Prospectus.

Section 7.  PAYMENTS TO THE DISTRIBUTOR

          7.1  With respect to classes and/or series of Shares which impose a
front-end sales charge, the Distributor shall receive and may retain any portion
of any front-end sales charge which is imposed on such sales and not reallocated
to selected dealers as set forth in the Prospectus, subject to the limitations
of Rule 2830 of the Conduct Rules of the NASD.  Payment of these amounts to the
Distributor is not contingent upon the adoption or continuation of any
applicable Plans.

          7.2  With respect to classes and/or series of Shares which impose a
contingent deferred sales charge, the Distributor shall receive and may retain
any contingent deferred sales charge which is imposed on such sales as set forth
in the Prospectus, subject to the limitations of Rule 2830 of the Conduct Rules
of the NASD.


                                          5
<PAGE>

Payment of these amounts to the Distributor is not contingent upon the adoption
or continuation of any Plan.



Section 8.  PAYMENT OF THE DISTRIBUTOR UNDER THE PLAN

          8.1  The Fund shall pay to the Distributor as compensation for
services under any Plans adopted by the Fund and this Agreement a distribution
and service fee with respect to the Fund's classes and/or series of Shares as
described in each of the Fund's respective Plans and this Agreement.

          8.2  So long as a Plan or any amendment thereto is in effect, the
Distributor shall inform the Board of the commissions and account servicing fees
with respect to the relevant class and/or series of Shares to be paid by the
Distributor to account executives of the Distributor and to broker-dealers,
financial institutions and investment advisers which have dealer agreements with
the Distributor.  So long as a Plan (or any amendment thereto) is in effect, at
the request of the Board or any agent or representative of the Fund, the
Distributor shall provide such additional information as may reasonably be
requested concerning the activities of the Distributor hereunder and the costs
incurred in performing such activities with respect to the relevant class and/or
series of Shares.

Section 9.  ALLOCATION OF EXPENSES

          The Fund shall bear all costs and expenses of the continuous offering
of its Shares (except for those costs and expenses borne by the Distributor
pursuant to a Plan and subject to the requirements of Rule 12b-1 under the
Investment Company Act), including fees and disbursements of its counsel and
auditors, in connection with the preparation and filing of any required
Registration Statements and/or Prospectuses under the Investment Company Act or
the Securities Act, and all amendments and supplements thereto, and preparing
and mailing annual and periodic reports and proxy materials to shareholders
(including but not limited to the expense of setting in type any such
Registration Statements, Prospectuses, annual or periodic reports or proxy
materials).  The Fund shall also bear the cost of expenses of making notice
filings for the Shares for sale, and, if necessary or advisable in connection
therewith, of qualifying the Fund as a broker or dealer, in such states of the
United States or other jurisdictions as shall be selected by the Fund and the
Distributor pursuant to Section 5.4 hereof and the cost and expense payable to
each such state for continuing notification therein until the Fund decides to
discontinue such notification pursuant to Section 5.4 hereof.  As set forth in
Section 8 above, the Fund shall also bear the expenses it assumes pursuant to
any Plan, so long as such Plan is in effect.

Section 10.  INDEMNIFICATION

          10.1 The Fund agrees to indemnify, defend and hold the Distributor,
its officers and directors and any person who controls the Distributor within
the meaning of Section 15 of the Securities Act, free and harmless from and
against any and all claims, demands, liabilities and expenses (including the
cost of investigating or defending such claims, demands or liabilities and any
reasonable counsel fees incurred in connection therewith) which the Distributor,
its officers, members or any such controlling person may incur under the
Securities Act, or under common law or otherwise, arising out of or based upon
any untrue statement of a material fact contained in the Registration Statement
or Prospectus or arising out of or based upon any alleged omission to state a
material fact required to be stated in either thereof or necessary to make the
statements in either thereof not misleading, except insofar as such claims,
demands, liabilities or expenses arise out of or are based upon any such untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with information furnished by the Distributor to the Fund
for use in the Registration Statement or Prospectus; provided, however, that
this indemnity agreement shall not inure to the benefit of any such officer,
member or controlling person unless a court of competent jurisdiction shall
determine in a final decision on the merits, that the person to be indemnified
was not liable by reason of willful misfeasance, bad faith or gross negligence
in the performance of its duties, or by reason of its reckless disregard of its
obligations under this Agreement (disabling conduct), or, in the absence of such
a decision, a reasonable determination, based upon a review of the facts, that
the indemnified person was not liable by reason of disabling conduct, by (a) a
vote of a majority of a quorum of directors or directors who are neither
"interested persons" of the Fund as defined in Section 2(a)(19) of the
Investment Company Act nor parties to the proceeding, or (b) an independent
legal counsel in a written opinion. The Fund's agreement to indemnify the
Distributor, its officers and members and any such controlling person as
aforesaid is expressly conditioned upon the Fund's being promptly notified of
any action brought against the Distributor, its officers or members, or any such
controlling person, such notification to be given by letter or telegram
addressed to the Fund at its principal business office.  The Fund agrees
promptly to notify the Distributor of the commencement of any litigation or
proceedings against it or any of its officers or directors in connection with
the issue and sale of any Shares.

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

                                     INTRODUCTION


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

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

     A majority of the Board of Directors/Trustees of the Fund, including a
majority of those Directors/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 this Plan or any agreements
related to it (the Rule 12b-1 Directors/Trustees), have determined by votes cast
in person at a meeting called for the purpose of voting on this Plan that there
is a reasonable likelihood that adoption and continuation of this Plan will
benefit the Fund and its shareholders.  Expenditures under this Plan by the Fund
for Distribution Activities (defined below) are primarily


                                         1

<PAGE>

intended to result in the sale of Class A shares of the Fund within the meaning
of paragraph (a)(2) of Rule 12b-1 promulgated under the Investment Company Act.

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

                                       THE PLAN

     The material aspects of the Plan are as follows:

1.   DISTRIBUTION ACTIVITIES

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

2.   PAYMENT OF SERVICE FEE 

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


                                         2

<PAGE>

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

3.   PAYMENT FOR DISTRIBUTION ACTIVITIES

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

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

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


                                         3

          Distribution Activities, including central office and branch expenses;

     (c)  amounts paid to Prudential Securities or Prusec for performing
          services under a selected dealer agreement between Prudential
          Securities or Prusec and the Distributor for sale of Class A shares of

          on account of, agents and indirect and overhead costs associated with
          Distribution Activities;  

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

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

4.   QUARTERLY REPORTS; ADDITIONAL INFORMATION

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

5.   EFFECTIVENESS; CONTINUATION

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

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

12b-1 Directors/Trustees, or by vote of a majority of the outstanding voting

materially the amounts payable under this Plan unless such amendment shall be
approved by the

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

2.   PAYMENT OF SERVICE FEE

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


                                          2

hereunder and shall pay such amounts monthly or at such other intervals as the
Board of Directors/Trustees may determine.

3.   PAYMENT FOR DISTRIBUTION ACTIVITIES

     The Fund shall pay to the Distributor as compensation for its services a
distribution fee of .75 of 1% per annum of the average daily net assets of the
Class C shares of the Fund for the performance of Distribution Activities.  The
Fund shall calculate and accrue daily amounts payable by the Class C shares of
the Fund hereunder and shall pay such amounts monthly or at such other intervals
as the Board of Directors/Trustees may determine.  Amounts payable under the
Plan shall be subject to the limitations of Rule 2830 of the NASD Conduct Rules.

     Amounts paid to the Distributor by the Class C shares of the Fund will not
be used to pay the distribution expenses incurred with respect to any other
class of shares of the Fund except that distribution expenses attributable to
the Fund as a whole will be allocated to the Class C shares according to the
ratio of the sale of Class C shares to the total sales of the Fund's shares over
the Fund's fiscal year or such other allocation method approved by the Board of
Directors/Trustees.  The allocation of distribution expenses among classes will
be subject to the review of the Board of Directors/Trustees.  Payments hereunder
will be applied to distribution expenses in the order in which they are
incurred, unless otherwise determined by the Board of Directors/Trustees.

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

          (a)  sales commissions (including trailer commissions) paid to, or on


                                          3
<PAGE>

          account of, account executives of the Distributor;

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

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

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

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

4.   QUARTERLY REPORTS; ADDITIONAL INFORMATION

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

     The Distributor will inform the Board of Directors/Trustees of the Fund of

                                          4

commissions and account servicing fees to be paid by the Distributor to account
executives of the Distributor and to broker-dealers and other financial
institutions which have selected dealer agreements with the Distributor.

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

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

12b-1 Directors/Trustees, or by vote of a majority of the outstanding voting
securities (as defined in the Investment Company Act) of the Class C shares of
the Fund.

7.   AMENDMENTS

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


                                          5

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

8.   RULE 12b-1 DIRECTORS/TRUSTEES

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

9.   RECORDS

     The Fund shall preserve copies of the Plan and any related agreements and
all reports made pursuant to Section 4 hereof, for a period of not less than six
years from the date of effectiveness of the Plan, such agreements or reports,

                                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.


                                       2
<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:

Class A....................................................................................    $37     $53     $69     $118
Class B....................................................................................    $62     $66     $72     $121
Class C....................................................................................    $24     $44     $76     $166

You would pay the following expenses on the same investment assuming no redemption:
Class A....................................................................................    $37     $53     $69     $118
Class B....................................................................................    $12     $36     $62     $121
Class C....................................................................................    $14     $44     $76     $166
</TABLE>

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.


                                       8
<PAGE>

  Because issuers of medium quality Municipal Bonds may choose not to have
their obligations rated, it is possible that a substantial portion of the
Fund's portfolio may consist of obligations which are not rated. The market for
rated bonds is usually broader than that for non-rated bonds, which may result
in less flexibility in disposal of such non-rated bonds.

  The Fund may also acquire Municipal Bonds which have been rated below medium
quality by the rating services if, in the judgment of the Fund's investment
adviser, the Bonds have the characteristics of medium quality obligations. In
determining whether Municipal Bonds which are not rated or which have been
rated below medium quality by the rating services have the characteristics of
rated Municipal Bonds of medium quality, the investment adviser will rely upon
information from various sources, including, if available, reports by the
rating services, research, analysis and appraisals of brokers and dealers and
the views of the Fund's directors and others regarding economic developments
and the creditworthiness of particular issuers.

  Municipal Bonds of medium quality are subject to fluctuation in value as a
result of changing economic circumstances as well as changes in interest rates.
Thus, while medium quality obligations will generally provide a higher yield
than do high quality Municipal Bonds of similar maturities, they are subject to
a greater degree of market fluctuation with less certainty of the issuer's
continuing ability to meet the payments of principal and interest when due and
may have speculative characteristics not present in bonds of higher quality. In
addition, obligations with longer maturities (e.g., 20 years or more) generally
offer both higher yields and greater exposure to market fluctuation from
changes in interest rates than do those with shorter maturities. Consequently,
shares of the Fund may not be suitable for persons who cannot assume the
somewhat greater risks of capital depreciation involved in seeking higher
tax-exempt yields.

  In recent years, there has been a narrowing of the yield spreads between
higher and lower quality Municipal Bonds and a reduction in the supply of
medium grade Municipal Bonds. As a result of these changing conditions in the
municipal securities markets, the investment adviser has invested a substantial
portion of the Fund's assets in higher quality Municipal Bonds. The investment
adviser intends to invest in medium grade Municipal Bonds to the extent market
conditions warrant.

  The interest rates payable on certain Municipal Bonds and Notes are not fixed
and may fluctuate based upon changes in market rates. Municipal Bonds and Notes
of this type are called variable rate obligations. The interest rate payable on
a variable rate obligation is adjusted either at predesignated intervals or
whenever there is a change in the market rate of interest on which the interest
rate payable is based. Other features may include the right whereby the Fund
may demand prepayment of the principal amount of the 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.


                                       9
<PAGE>

  Some municipal securities, such as zero coupon municipal securities, do not
pay current interest but are purchased at a discount from their face values.
The discount approximates the total amount of interest the security will accrue
and compound over the period until maturity or the particular interest payment
date at a rate of interest reflecting the market rate of the security at the
time of issuance. Zero coupon securities do not require the periodic payment of
interest. These investments benefit the issuer by mitigating its need for cash
to meet debt service, but also require a higher rate of return to attract
investors who are willing to defer receipt of cash. These investments may
experience greater volatility in market value than securities that make regular
payments of interest.

  The Fund may be able to reduce the risk of fluctuations in asset value caused
by changes in interest rates by hedging its portfolio through the use of
financial futures. During or in anticipation of a decline in interest rates,
the Fund may purchase futures contracts to hedge against subsequent purchases
of long-term bonds at higher prices. During or in anticipation of an increase
in interest rates, the Fund may hedge its portfolio securities by selling
futures contracts for the purpose of limiting the exposure of its portfolio to
the resulting decrease in value. There are risks associated with hedging
transactions and there can be no assurance that hedges will have the intended
result. See "Hedging and Return Enhancement Strategies" below.

  Also, the Fund may purchase secondary market insurance on Municipal Bonds and
Notes which it holds or acquires. Although the fee for secondary market
insurance will reduce the yield of the insured Bonds and Notes, such insurance
would be reflected in the market value of the municipal obligation purchased
and may enable the Fund to dispose of a defaulted obligation at a price similar
to that of comparable municipal obligations which are not in default.

  Insurance is not a substitute for the basic credit of an issuer, but
supplements the existing credit and provides additional security therefor.
While insurance coverage for the Municipal Bonds and Notes held by the Fund
reduces credit risk by providing that the insurance company will make timely
payment of principal and interest if the issuer defaults on its obligation to
make such payment, it does not afford protection against fluctuation in the
price, i.e., the market value, of the municipal obligations caused by changes
in interest rates and other factors, nor in turn against fluctuations in the
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


                                       10
<PAGE>

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.

  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


                                       11
<PAGE>

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 11/2% 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). 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.


                                       12
<PAGE>

  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 circumstances, this may serve as a hedge against a loss
of principal, but is usually referred to as an aspect of risk management.


                                       13
<PAGE>

  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.


                                       14
<PAGE>

  Anticipatory Hedging. The Fund may also purchase call options on futures
contracts as a hedge against an increase in the value of securities the Fund
might intend to acquire as a result of declining interest rates.

  Writing a put option on a futures contract may serve as a partial
anticipatory hedge against an increase in the value of debt securities the Fund
might intend to acquire. If the futures price at expiration of the option is
above the exercise price, the Fund retains the full amount of the option
premium which provides a partial hedge against any increase that may have
occurred in the price of the debt securities the Fund intended to acquire. If
the market price of the underlying futures contract is below the exercise price
when the option is exercised, the Fund would incur a loss, which may be wholly
or partially offset by the decrease in the value of the securities the Fund
might intend to acquire.

  Whether options on interest rate futures contracts are subject to or exempt
from the 5% CFTC limit depends on whether the purpose of the options
constitutes a bona fide hedge.

  Risk Management and Return Enhancement. Writing a put option that does not
relate to securities the Fund intends to acquire would be a return enhancement
strategy which would result in a loss if interest rates rise.

  Similarly, writing a covered call option on a futures contract is also a
return enhancement strategy. If the market price of the underlying futures
contract at expiration of a written call option is below the exercise price,
the Fund would retain the full amount of the option premium increasing the
income of the Fund. If the futures price when the option is exercised is above
the exercise price, however, the Fund would sell the underlying securities
which was the cover for the contract and incur a gain or loss depending on the
cost basis for the underlying assets.

  Writing a covered call option as in any return enhancement strategy can also
be considered a partial hedge against a decrease in the value of a Fund's
portfolio securities. The amount of the premium received acts as a partial
hedge against any decline that may have occurred in the Fund's debt securities.

  Risks Relating to Transactions in Futures Contracts and Options Thereon

  The Fund's ability to establish and close out positions in futures contracts
and options on futures contracts would be impacted by the liquidity of these
markets. Although the Fund generally would purchase or sell only those futures
contracts and options thereon for which there appeared to be a liquid market,
there is no assurance that a liquid market on an exchange will exist for any
particular futures contract or option at any 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


                                       15
<PAGE>

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 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.

<PAGE>

  Municipal Lease Obligations

  The Fund may also invest in municipal lease obligations. A municipal lease
obligation is a municipal security the interest on and principal of which is
payable out of lease payments made by the party leasing the facilities financed
by the issue. Typically, municipal lease obligations are issued by a state or
municipal financing authority to provide funds for the construction of
facilities (e.g., schools, dormitories, office buildings or prisons). The
facilities are typically used by the state or municipality pursuant to a lease
with a financing authority. Certain municipal lease obligations may trade
infrequently. Accordingly, the investment adviser will monitor the liquidity of
municipal lease obligations under the supervision of the Board of Directors.
Municipal lease obligations will not be considered illiquid for purposes of the
Fund's 15% limitation on illiquid securities provided the investment adviser
determines that there is a readily available market for such securities. See
"Illiquid Securities" below and "Investment Objective and Policies-Illiquid
Securities" in the Statement of Additional Information.

  Illiquid Securities

  The Fund may hold up to 15% of its net assets in illiquid securities,
including repurchase agreements which have a maturity of longer than seven days
or contractual restrictions on resale and securities that are not readily
marketable. Securities, including municipal lease obligations, that have a
readily available market are not considered illiquid for the purposes of this
limitation. The investment adviser will monitor the liquidity of such
securities under the supervision of the Directors. See "Investment Objectives
and Policies-Illiquid Securities" in the Statement of Additional Information.
Repurchase agreements subject to demand are deemed to have a maturity equal to
the notice period.

  Investments in Securities of Other Investment Companies

  The Fund may invest up to 10% of its total assets in shares of other
investment companies. To the extent that the Fund does invest in securities of
other investment companies, shareholders of the Fund may be subject to
duplicate management and advisory fees.

  Borrowing

  The Fund may borrow an amount equal to no more than 331/3% 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 331/3% 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.


                                       17
<PAGE>

  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 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
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. PIFM is
organized in 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.


                                       18
<PAGE>

  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
portfolio manager since July 1994 and serves as the portfolio manager of a
number of other portfolios managed by PI. He was employed by Fidelity
Investments from 1982 to 1985 as a senior bond analyst and from 1985 to 1994 as
a portfolio manager, most recently of Fidelity Adviser High Income Municipal
Fund.

  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 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.


                                       19
<PAGE>

  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 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.


                                       20
<PAGE>

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.

<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.,
                                       22

<PAGE>


other industry publications, business periodicals, and market indices. See
"Performance Information" in the Statement of Additional Information. Further
performance information is contained in the Fund's annual and semi-annual
reports to shareholders, which may be obtained without charge. See "Shareholder
Guide-Shareholder Services-Reports to Shareholders."

                       TAXES, DIVIDENDS AND DISTRIBUTIONS


Taxation of the Fund

  The Fund has elected to qualify and intends to remain qualified as a
regulated investment company under the Internal Revenue Code. Accordingly, the
Fund will not be subject to federal income taxes on its net investment income
and 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-
                                       23

<PAGE>


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.
                                       24

<PAGE>



  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 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
                                       25

<PAGE>


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 at a

                               SHAREHOLDER GUIDE


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.

  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.
                                       26

<PAGE>



  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.

ALTERNATIVE PURCHASE PLAN

  The Fund offers 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).

<PAGE>


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

  Financial advisers and other sales agents who sell shares of the Fund will
receive different compensation for selling Class A, Class B and Class C shares
and will generally receive more compensation initially for selling Class A and
Class B shares than for selling Class C shares.

  In selecting a purchase alternative, you should consider, among other things,
(1) the length of time you expect to hold your investment, (2) the amount of
any applicable sales charge (whether imposed at the time of purchase or
redemption) and distribution-related fees, as noted above, (3) whether you
qualify for any reduction or waiver of any applicable sales charge, (4) the
various exchange privileges among the different classes of shares (see "How to
Exchange Your Shares" below) and (5) the fact that Class B shares automatically
convert to Class A shares approximately seven years after purchase (see
"Conversion Feature-Class B Shares" below).

  The following is provided to assist you in determining which method of
purchase best suits your individual circumstances and is based on current fees
and expenses being charged to the Fund:

  If you intend to hold your investment in the Fund for less than 5 years and
do not qualify for a reduced sales charge on Class A shares, since Class A
shares are subject to a maximum initial sales charge of 3% and Class B shares
are subject to a CDSC of 5% which declines to zero over a 6 year period, you
should consider purchasing Class C shares over either Class A or Class B
shares.

  If you intend to hold your investment for more than 5 years and do not
qualify for a reduced sales charge on Class A shares, since Class B shares
convert to Class A shares approximately 7 years after purchase and because all
of your money would be invested initially in the case of Class B shares, you
should consider purchasing Class B shares over either Class A or Class C
shares.

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

  If you do not qualify for a reduced sales charge on Class A shares and you
purchase Class C shares, you would have to hold your investment for more than 4
years for the higher cumulative annual distribution-related fee on Class C
shares to exceed the initial sales charge plus cumulative annual
distribution-related fees on Class A shares. This does not take into account
the time value of money, which further reduces the impact of the higher Class C
distribution-related fee on the investment, fluctuations in NAV, the effect of
the return on the investment over this period of time or redemptions during
which the CDSC is applicable.
                                       28

<PAGE>



  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.

  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
                                       29

<PAGE>


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 concerning redemptions should be
sent to the Fund in care of
                                       30

<PAGE>


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 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 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
                                       31

<PAGE>


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 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>
<CAPTION>

             Contingent Deferred Sales
 Year Since   Charge as a Percentage
  Purchase    of Dollars Invested or
Payment Made    Redemption Proceeds
- ------------ -------------------------
<S>          <C>
First.......                      5.0%
Second......                      4.0%
Third.......                      3.0%
Fourth......                      2.0%
Fifth.......                      1.0%
Sixth.......                      1.0%
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 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 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.
                                       33

<PAGE>



  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 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.

                                       34

  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.

  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).
                                       35

<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 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.

telephone at (800) 225-1852 (toll-free) or, from outside the U.S.A., at (908)

Prudential Municipal Bond Fund
- --------------------------------
 
PROSPECTUS DATED JULY 1, 1998
- ----------------------------------------------------------------
 
Prudential Municipal Bond Fund (the Fund) is an open-end, diversified,
management investment company, or mutual fund, consisting of three separate
portfolios--the High Income Series, the Insured Series and the Intermediate
Series (collectively, the Series). The investment objectives of the Series are
as follows: (i) the objective of the High Income Series is to provide the
maximum amount of income that is eligible for exclusion from federal income
taxes, (ii) the objective of the Insured Series is to provide the maximum amount
of income that is eligible for exclusion from federal income taxes consistent
with the preservation of capital and (iii) the 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 each
Series will seek income that is eligible for exclusion from federal income
taxes, a portion of the dividends and distributions paid by each Series (and, in
particular, the High Income Series) may be treated as a preference item for
purposes of the alternative minimum tax. Each Series seeks to achieve its
objective through the separate 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, each 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 HIGH INCOME SERIES MAY INVEST IN LOWER RATED BONDS, COMMONLY KNOWN AS JUNK
BONDS. INVESTMENTS OF THIS TYPE ARE SUBJECT TO A GREATER RISK OF LOSS OF
PRINCIPAL AND INTEREST, INCLUDING DEFAULT RISK, THAN HIGHER RATED BONDS.
PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS ASSOCIATED WITH AN INVESTMENT IN
THIS SERIES. See "How the Fund Invests--Investment Objectives and Policies--The
High Income Series--Risk Factors Relating to Investing in High Yield
Securities."
 
The Insured Series invests at least 70% of its assets in insured obligations
under normal conditions. The insurance relates to the timely payment of
principal and interest on portfolio investments and not to the shares of the
Series.
 
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 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 July 1, 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.
 
- --------------------------------------------------------------------------------
 
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.
<PAGE>
                                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 Income Series, the Insured Series and the Intermediate
  Series.
 
  WHAT ARE THE SERIES' INVESTMENT OBJECTIVES?
    The investment objective of the High Income Series is to provide the
  maximum amount of income that is eligible for exclusion from federal income
  taxes. The investment objective of the Insured 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 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. Each Series seeks to achieve its objective through
  the separate investment policies described in this Prospectus. There can be
  no assurance that the Series' objectives will be achieved. See "How the Fund
  Invests--Investment Objectives and Policies" at page 18.
 
  WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?
    The High Income Series invests 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. The Insured Series invests
  primarily in insured municipal obligations. Although the insurance policies
  protect against the failure to make timely payment of principal and interest
  on the insured municipal obligations, the price of the municipal obligations
  and the stability of the Series' net asset value per share (NAV) are not
  insured. The 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. 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 18. Each 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 Fund.
  See "How the Fund Invests--Hedging Strategies--Risks of Hedging Strategies"
  at page 25. 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 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. As of May 31, 1998, PIFM served as manager or administrator to 67
  investment companies, including 45 mutual funds, with aggregate assets of
  approximately $65 billion. The Prudential Investment Corporation (PIC),
  doing business as Prudential Investments (the Subadviser) 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 29.
 
  WHO DISTRIBUTES THE FUND'S SHARES?
    On and after July 1, 1998, Prudential Investment Management Services LLC
  (the Distributor), will act as the Distributor of the Fund's Class A, Class
  B, Class C and Class Z shares. Before July 1, 1998, Prudential Securities
  Incorporated (Prudential Securities) served as Distributor of Fund shares.
  Prudential Securities and Prudential Investment Management Services LLC are
  each referred to as the Distributor. 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 of each
  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 each 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 each Series. The
  Distributor incurs the expense of distributing the Fund's 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 29.

  WHAT IS THE MINIMUM INVESTMENT?
 
    The minimum initial investment is $1,000 for Class A and Class B shares
  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 37 and "Shareholder Guide--Shareholder Services" at
  page 46.
 
  HOW DO I PURCHASE SHARES?
 
    You may purchase shares of the Fund through the Distributor or brokers or
  dealers that have entered into agreements to act as participating or
  introducing brokers for the Distributor (Dealers), including Prudential
  Securities or Pruco Securities Incorporated (Prusec), 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 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 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 NAV without any sales charge. Dealers may charge their
  customers a separate fee for handling purchase transactions. See "How the
  Fund Values its Shares" at page 32 and "Shareholder Guide--How to Buy Shares
  of the Fund" at page 37.
 
  WHAT ARE MY PURCHASE ALTERNATIVES?
 
    The Fund offers four classes of shares through this Prospectus:
 
     - 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. 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.
 
     - Class Z Shares:   Sold without either an initial sales charge or CDSC
                         to a limited group of investors. Class Z shares are
                         not subject to any ongoing service or distribution
                         expenses.
 
    See "Shareholder Guide--Alternative Purchase Plan" at page 38.
 
  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.
  However, 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 41. Participants in programs sponsored by Prudential Retirement
  Services should contact their client representative for more information
  about selling their Class Z shares.
 
  HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?
 
    The Fund 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 a 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 33.

(a)  Dealers may independently 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
     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 the Series
     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."
 
(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, 1998,
     without taking into account the management fee waiver. At the current level
     of management fee waiver (10%) for the High Income Series, Management Fees
     for the High Income Series would be .45% for all classes and Total Fund
     Operating Expenses for Class A, B, C and Class Z shares would be .62%,
     1.02%, 1.27% and .52%, respectively for the High Income Series. The expense
     information in the table with respect to the Insured and Intermediate
     Series has been restated to reflect current fees. Effective August 31,
     1997, PIFM eliminated its management fee waiver (10%) with respect to the
     Insured and Intermediate Series. See "How the Fund is Managed--Fee Waivers
     and Subsidy."
 
(d)  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% and up to 1% of
     the average daily net assets of the Class A and Class C shares,
     respectively, the Distributor may voluntarily waive all or a portion of the
     distribution fees as it may determine from time to time. Any such waivers
     may be terminated at any time without prior notice to shareholders. The fee
     table reflects the 12b-1 fees that are estimated to be incurred by the Fund
     during its current fiscal year. Total Fund Operating Expenses of the Class
     A and Class C shares without such waivers would be .87% and 1.57%,
     respectively, of the High Income Series, .91% and 1.61%, respectively, of
     the Insured Series and 1.53% and 2.23%, respectively, of the Intermediate
     Series. See "How the Fund is Managed--Distributor."

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 OBJECTIVES WILL BE ACHIEVED. See "Investment Objectives and
Policies" in the Statement of Additional Information. Although each Series will
seek income that is eligible for exclusion from federal income taxes, a portion
of the dividends and distributions paid by each Series (and, in particular, the
High Income 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 any Series of this
Fund can decrease in value and you can lose money.
 
  EACH 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.
 
  EACH SERIES PURSUES ITS INVESTMENT OBJECTIVE THROUGH THE SEPARATE INVESTMENT
POLICIES DESCRIBED BELOW. These policies differ with respect to the maturity and
quality of portfolio securities in which a Series may invest and can affect the
yield for each Series and the degree of market risk and credit risk to which
each Series is subject.
 
  EACH 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 EACH OF
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 generally 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. From time to time, a Series may own the majority of a
municipal obligation. Such majority-owned holdings may present additional market
and credit risks.
 
  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 purposes, including the construction
of
 
                                       18
<PAGE>
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.
 
  DURING NORMAL MARKET CONDITIONS, THE ASSETS OF EACH SERIES WILL BE INVESTED SO
THAT IT WILL HAVE AT LEAST 80% OF ITS NET ASSETS INVESTED IN MUNICIPAL
OBLIGATIONS. However, when the Fund's investment adviser believes that market
conditions warrant a temporary defensive investment posture or when necessary to
meet large redemptions, a 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.
Each 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. Each 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.
 
  THE HIGH INCOME SERIES
 
  THE HIGH INCOME SERIES WILL INVEST PRIMARILY IN MUNICIPAL OBLIGATIONS WHICH
ARE RATED B OR BETTER BY MOODY'S INVESTORS SERVICE (MOODY'S) OR STANDARD &
POOR'S RATINGS GROUP (S&P) OR A SIMILAR NATIONALLY RECOGNIZED STATISTICAL RATING
ORGANIZATION (NRSRO) AND WHICH GENERALLY HAVE MATURITIES IN EXCESS OF TEN YEARS
AT THE TIME OF PURCHASE, ALTHOUGH THE SERIES ALSO WILL INVEST IN MUNICIPAL
OBLIGATIONS HAVING MATURITIES RANGING FROM ONE YEAR TO TEN YEARS, PROVIDED THAT
THE WEIGHTED AVERAGE MATURITY OF THE SERIES' INVESTMENT PORTFOLIO REMAINS WITHIN
THE FIFTEEN TO THIRTY YEAR RANGE. Securities rated Baa by Moody's or BBB by S&P,
although considered to be investment grade, lack outstanding investment
characteristics and in fact have speculative characteristics as well. Securities
rated Ba or BB or lower by Moody's or S&P, respectively, are generally
considered to be predominantly speculative with respect to the issuer's capacity
to pay interest and repay principal and are commonly referred to as junk bonds.
While such securities may have some quality and protective characteristics,
those are outweighed by large uncertainties or major risk exposures to adverse
conditions. See "Risk Factors Relating to Investing in High Yield Securities"
below and "Description of Security Ratings" in the Appendix. 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.
 
  THE SERIES MAY ALSO INVEST IN MUNICIPAL SECURITIES WHICH ARE NOT RATED IF,
BASED UPON A CREDIT ANALYSIS BY THE FUND'S INVESTMENT ADVISER, THE INVESTMENT
ADVISER BELIEVES THAT SUCH SECURITIES ARE OF COMPARABLE QUALITY TO RATED
MUNICIPAL SECURITIES IN WHICH THE SERIES MAY INVEST. The High Income Series
normally can be expected to offer the highest yields of the three Series, but it
will also be subject to the greatest market and credit risk.
 
  THE SERIES ALSO MAY INVEST IN SHORT-TERM MUNICIPAL OBLIGATIONS (I.E., CASH
EQUIVALENTS) THAT ARE, AT THE TIME OF PURCHASE, RATED WITHIN THE FOUR HIGHEST
QUALITY GRADES AS DETERMINED BY EITHER MOODY'S (CURRENTLY MIG 1, MIG 2, MIG 3
AND MIG 4 FOR NOTES AND P-1, P-2 AND P-3 FOR COMMERCIAL PAPER) OR S&P (CURRENTLY
A-1, A-2 AND A-3 FOR COMMERCIAL PAPER AND SP-1 AND SP-2 FOR NOTES). See "Other
Investments and Policies--General" below.
 
  The Series may also invest up to 10% of its total assets in debt securities of
financially troubled and operationally troubled obligors (distressed
securities). Financially troubled obligors include obligors involved in
bankruptcy or reorganization proceedings or financial restructurings or
otherwise in default on their obligations. Operationally troubled obligors are
ones experiencing poor operating results that may have severely depressed
earnings or have special competitive or product obsolescence problems.
 
  The Series is permitted to invest in defaulted securities and in low quality
debt securities having a rating of D or better as determined by S&P or Moody's
or having a comparable rating determined by another NRSRO, or in unrated
securities which, in the opinion of the investment adviser, are of equivalent
quality. See "Risk Factors Relating to Investing in High Yield Securities"
 
                                       19
<PAGE>
below and the "Description of Security Ratings" in the Appendix. Such
lower-quality debt securities are considered to have speculative
characteristics, and involve greater risk of default or price changes due to
changes in the obligor's creditworthiness, or they may already be in default.
The market prices of these securities may fluctuate more than higher-quality
securities and may decline significantly in periods of general or regional
economic difficulty.
 
  The Subadviser maintains a fixed-income research group which the Series'
portfolio manager may consult in managing the portfolio and in researching
financially troubled and operationally troubled obligors. The Series' portfolio
manager reviews on an ongoing basis financially troubled and operationally
troubled obligors, including prospective purchases and portfolio holdings of the
Series. The portfolio manager has broad access to research and financial
reports, data retrieval services and industry analysts.
 
  RISK FACTORS RELATING TO INVESTING IN HIGH YIELD SECURITIES. 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 AND THE
MARKET PERCEPTION OF THE CREDITWORTHINESS OF THE ISSUER (MARKET RISK). Lower
rated (I.E., high yield) securities or non-rated securities of comparable
quality 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 considers both
credit risk and market risk in making investment decisions for the Series.
Investors should carefully consider the relative risks of investing in high
yield securities and understand that such securities are not generally meant for
short-term trading.
 
  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.
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.
 
  Debt rated Ba, B, Caa, Ca and C by Moody's, and debt rated BB, B, CCC, CC and
C by S&P is regarded by the rating agency, on balance, as predominantly
speculative with respect to the issuer's capacity to pay interest and repay
principal in accordance with the terms of the obligation. Among junk bonds,
Ba/BB indicates the lowest degree of speculation and C/D the highest degree of
speculation. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions. Debt rated C by S&P is the lowest rated debt
that is not in default as to principal or interest and such issues so rated can
be regarded as having extremely poor prospects of ever attaining any real
investment standing. Such securities are also generally considered to be subject
to greater risk than securities with higher ratings with regard to a
deterioration of general economic conditions. Debt rated D by S&P is in payment
default. Moody's does not have a D rating. See the "Description of Security
Ratings" in the Appendix.
 
  Ratings of fixed-income securities represent the rating agency's opinion
regarding their credit quality and are not a guarantee of quality. Rating
agencies attempt to evaluate the safety of principal and interest payments and
do not evaluate the risks of fluctuations in market value. Also, rating agencies
may fail to make timely changes in credit ratings in response to subsequent
events, so that an issuer's current financial condition may be better or worse
than a rating indicated.
 
                                       20
<PAGE>
  From time to time proposals have been introduced to limit the use, or tax and
other advantages, of municipal securities which, if enacted, could adversely
affect the Series' NAV and investment practices. Such proposals could also
adversely affect the secondary market for high yield municipal securities, the
financial condition of issuers of these securities and the value of outstanding
high yield municipal securities. Reevaluation of the Series' investment
objective and structure might be necessary in the future due to market
conditions which may result from future changes in state or federal law.
 
  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.
 
  During the year ended April 30, 1998, the monthly dollar weighted average
ratings of the debt obligations held by the Series, expressed as a percentage of
the Series' total investments, were as follows:

  THE INSURED SERIES
 
  THE INSURED SERIES WILL INVEST PRIMARILY IN MUNICIPAL OBLIGATIONS WHICH ARE
(i) INSURED BY AN ENTITY WHOSE CLAIMS-PAYING ABILITY AT THE TIME OF PURCHASE IS
RATED Aaa BY MOODY'S OR AAA BY S&P, OR A SIMILAR NRSRO, SO THAT THE OBLIGATION
IS RATED AAA OR Aaa OR MEETS THE ELIGIBILITY CRITERIA IMPOSED BY SUCH INSURERS,
(ii) RATED Aaa OR AAA BY MOODY'S OR S&P, RESPECTIVELY, OR A SIMILAR NRSRO (OR,
IN THE CASE OF NOTES OR VARIABLE RATE SECURITIES, A-1, P-1, MIG 1 OR SP-1),
BASED ON THE CREDIT OF THE ISSUER OR (iii) BACKED BY THE FULL FAITH AND CREDIT
OF THE U.S. GOVERNMENT. The Series may also invest up to 5% of its total assets
in municipal obligations which are rated A/A or Aa/AA by Moody's or S&P,
respectively, or a similar NRSRO. See "Description of Security Ratings" in the
Appendix. The Series may also invest in municipal securities which are not rated
if, based upon a credit analysis by the Fund's investment adviser, the
investment adviser believes that such securities are of comparable quality to
other municipal securities that the Series may purchase.
 
  UNDER NORMAL CONDITIONS, AT LEAST 70% OF THE SERIES' TOTAL ASSETS WILL CONSIST
OF INSURED OBLIGATIONS. AS OF APRIL 30, 1998, APPROXIMATELY 90% OF THE SERIES'
TOTAL ASSETS WERE OBLIGATIONS INSURED BY A MUNICIPAL BOND INSURER. This
insurance may be provided either (i) under a new issue insurance policy obtained
by the issuer or underwriter of a bond or note or
 
                                       21
<PAGE>
(ii) under a secondary market insurance policy on a particular bond or note
purchased either by the Series or a previous bondholder or noteholder. See
"Insurance" below. As noted above, the Series will acquire insurance only from,
and purchase municipal bonds and notes insured by, insurers whose claims-paying
ability is rated AAA or Aaa at the time of purchase. Changes in the financial
condition of an insurer could result in a subsequent reduction or withdrawal of
this rating. In each case, the insurance policies protect only against the
timely payment of principal and interest on the insured municipal bonds and
notes. The price of the municipal obligations, which may fluctuate due to
changes in interest rates generally or factors affecting the credit of the
insurer, and the stability of the Series' NAV are not insured.
 
  INSURANCE. The Series may at times purchase secondary market insurance on
municipal bonds and notes which it holds or acquires. Secondary market insurance
would be reflected in the market value of the municipal obligation 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 municipal bonds and notes held by the Insured 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 Insured Series.
 
  The ratings of insured municipal obligations depend, in substantial part, on
the creditworthiness of the insurer; thus their value will fluctuate largely on
the basis of factors relating to the insurer's ability to satisfy its
obligations, as well as on market factors generally. It is anticipated that,
under current market conditions, a great majority of the municipal obligations
held by the Insured Series will be insured by the following entities, among
others: MBIA Insurance Corporation, AMBAC Indemnity Corporation, Financial
Guaranty Insurance Company and Financial Security Assurance Inc. S&P rates
securities insured by all of these companies AAA. Moody's rates securities
insured by all of these companies Aaa. The Insured Series may, from time to
time, purchase municipal securities insured by other entities or acquire
insurance coverage for individual uninsured municipal securities directly from
another insurer provided any such entity has a claims-paying ability rated AAA
or Aaa by S&P or Moody's, respectively. See "Investment Objectives and
Policies--The Insured Series" in the Statement of Additional Information for
additional information concerning the insurers.
 
  New issue insurance is obtained by the issuer or underwriter upon issuance of
a bond or note, and the insurance premiums are reflected in the price of such
bond or note. Insurance premiums with respect to secondary insurance may, on the
other hand, be paid by the Series. Premiums paid for secondary market insurance
will be treated as capital costs, increasing the cost basis of the investment
and thereby reducing the effective yield of the investment.
 
  THE INTERMEDIATE SERIES
 
  THE INTERMEDIATE 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 INTERMEDIATE SERIES WILL BE RATED AT LEAST Baa BY
MOODY'S OR BBB BY S&P OR A SIMILAR NRSRO AT THE TIME OF PURCHASE OR BE NON-RATED
OBLIGATIONS OF COMPARABLE QUALITY IN THE OPINION OF THE FUND'S INVESTMENT
ADVISER. 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. See "Description of Security Ratings" in the
Appendix.
 
  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
 
                                       22
<PAGE>
devices such as a call, refunding or redemption provision, in which case the
maturity date will be the date on which it is probable 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 INTERMEDIATE 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 Fund's 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.
 
                                       23
<PAGE>
  BORROWING
 
  Each 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 and to take advantage of investment opportunities or for
the clearance of transactions. Each Series may pledge up to 33 1/3% of the value
of its total assets to secure these borrowings. If a Series' asset coverage for
borrowings falls below 300%, the Fund will take prompt action to reduce its
borrowings. If the 300% asset coverage should decline as a result of market
fluctuations or other reasons, the Fund may be required to sell portfolio
securities to reduce the debt and restore the 300% asset coverage, even though
it may be disadvantageous from an investment standpoint to sell securities at
that time.
 
  If a Series borrows to invest in securities, any investment gains made on the
securities in excess of interest paid on the borrowing will cause the NAV 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 Series' NAV 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
 
  EACH 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. A SERIES, AND THUS AN INVESTOR, MAY LOSE MONEY THROUGH
UNSUCCESSFUL USE OF THESE STRATEGIES. In that regard, the Intermediate Series
may sell futures contracts to create synthetic positions by partially hedging
longer-term obligation positions. See "Investment Objectives and Policies--The
Intermediate Series" above. The successful use of futures contracts and options
thereon by a 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. A
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.
 
  EACH 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. A Series may purchase and sell
futures contracts and options thereon for bona fide hedging transactions, except
that a 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, a 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
 
                                       24
<PAGE>
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 a 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 a 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. Each
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.
 
  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
a 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 a Series to hedge effectively. There is
also a risk of loss by a 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 A 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.
 
  RISKS OF HEDGING STRATEGIES
 
  PARTICIPATION IN THE OPTIONS OR FUTURES MARKETS INVOLVES INVESTMENT RISKS AND
TRANSACTION COSTS TO WHICH A SERIES WOULD NOT BE SUBJECT ABSENT THE USE OF THESE
STRATEGIES. A SERIES, AND THUS AN INVESTOR, MAY LOSE MONEY THROUGH 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 Fund may leave the Fund 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;
and (5) the possible inability of the Fund to purchase or sell a portfolio
security at a time that otherwise would be favorable for it to do so, or the
possible need for the Fund to sell a portfolio security at a disadvantageous
time, due to the need for the Fund to maintain cover or to segregate securities
in connection with hedging transactions. See "Investment Objectives and
Policies" in the Statement of Additional Information.

OTHER INVESTMENTS AND POLICIES
 
  GENERAL
 
  EACH SERIES MAY INVEST MORE THAN 5% OF ITS 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.
 
  Each 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.
 
  Each 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.
 
  WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
 
  Each 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. During the period between
purchase and settlement, no interest accrues to the purchaser. In the case of
purchases by a 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, each 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 a 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 NAV. 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. Each Series will establish a
segregated account in which it will maintain cash or other liquid assets 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 a Series may be required to accept on the settlement date may be less than
the market value of the obligation on that date.
 
  Each 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
 
  Each 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
 
                                       26
<PAGE>
(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
 
  Each 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
 
  Each 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. Each Series participates in a
joint repurchase account with other investment companies managed by PIFM
pursuant to an order of the Commission.
 
  SECURITIES OF OTHER INVESTMENT COMPANIES
 
  Each Series may invest up to 10% of its total assets in securities of other
investment companies. To the extent that a Series does invest in securities of
other investment companies, shareholders of the Series may be subject to
duplicate management and advisory fees.
 
  ILLIQUID SECURITIES
 
  Each 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 Subadviser will
monitor the liquidity of such restricted securities under the supervision of the
Trustees. A 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 each 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
municipal lease obligations, the investment adviser also considers: (1) the
willingness of the municipality to continue, annually or
 
                                       27
<PAGE>
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 Fund may lend its portfolio securities to brokers or dealers, banks or
other recognized institutional borrowers of securities, provided that the
borrower at all times maintains cash or other liquid assets or secures an
irrevocable letter of credit in favor of the Fund in an amount equal to at least
100%, determined daily, of the market value of the securities loaned which are
segregated pursuant to applicable regulations. During the time portfolio
securities are on loan, the borrower will pay the Fund an amount equivalent to
any dividend or interest paid on such securities and the Fund may invest the
cash collateral and earn additional income, or it may receive an agreed upon
amount of interest income from the borrower. As with any extensions of credit,
there are risks of delay in recovery and in some cases loss of rights in the
collateral should the borrower of the securities fail financially. The Fund will
not lend more than 33% of the value of its total assets. See "Investment
Objectives and Policies--Municipal Securities--Lending of Securities" in the
Statement of Additional Information. The Fund may pay reasonable administration
and custodial fees in connection with a loan.
 
  PORTFOLIO TURNOVER
 
  The Series do 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 a Series'
portfolio securities, excluding securities having a maturity at the date of
purchase of one year or less. High portfolio turnover (over 100%) of a Series
may involve correspondingly greater brokerage commissions (or markups) 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.
 
INVESTMENT RESTRICTIONS
 
  Each 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 each
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, 1998, the total expenses as a percentage
of average net assets were .62%, 1.02%, 1.27% and .52% of the Class A, Class B,
Class C and Class Z shares, respectively, of the High Income Series, .69%,
1.09%, 1.34% and .60% of the Class A, Class B, Class C and Class Z shares,
respectively, of the Insured Series, and 1.31%, 1.71%, 1.96% and 1.21% of the
Class A, Class B, Class C and Class Z shares, respectively, of the Intermediate
Series. See "Financial Highlights."

CENTER THREE, 100 MULBERRY STREET, NEWARK, NEW JERSEY 07102-4077, 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 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 is
organized in 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 April 30, 1998, PIFM received a
management fee of .45%, .48% and .48% of average daily net assets on behalf of
the High Income Series, Insured Series and Intermediate Series, respectively.
See "Manager" in the Statement of Additional Information.
 
  PIFM may from time to time waive its management fee and subsidize operating
expenses of a Series. PIFM has agreed to waive 10% of its management fee
(approximately .05 of 1% of average net assets, as annualized), with respect to
the High Income Series. See "Fund Expenses." The Fund is not required to
reimburse PIFM for such fee waiver. Fee waivers and expense subsidies will
increase a Series' yield and total return. See "How the Fund Calculates
Performance."
 
  As of May 31, 1998, PIFM served as the manager to 45 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 $65 billion.

                                       29
<PAGE>
  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. THE DISTRIBUTOR INCURS THE EXPENSES OF
DISTRIBUTING THE FUND'S 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, 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 associated with the sale of Fund 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 Fund is obligated to pay distribution and/or service fees
to the Distributor as compensation for its distribution and service activities,
not as reimbursement for specific expenses incurred. If the Distributor's
expenses exceed its distribution and service fees, the Fund will not be
obligated to pay any additional expenses. If the Distributor's expenses are less
than such distribution and service fees, it will retain its full fees and
realize a profit.
 
  The distribution and/or service fees may also be used by the Distributor to
compensate on a continuing basis 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 Fund's shares and the
maintenance of related shareholder accounts.
 
  UNDER THE CLASS A PLAN, EACH 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 up to .25 of 1%) may not exceed
 .30 of 1% of the average daily net assets of the Class A shares.
 
  UNDER THE CLASS B AND CLASS C PLANS, EACH 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 shareholders accounts. The
Distributor 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, 1998, each 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 record 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 each 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
 
                                       30
<PAGE>
Trustees), vote annually to continue the Plan. Each Plan may be terminated with
respect to a 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 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 and other persons which distribute
shares of the Fund (including Class Z shares). Such payments may be calculated
by reference to the NAV 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.
 
FEE WAIVERS AND SUBSIDY
 
  PIFM may from time to time voluntarily waive all or a portion of its
management fee and subsidize all or a portion of the operating expenses of the
Fund. Effective August 31, 1997, PIFM discontinued its waiver of 10% of its
management fee related to the Insured Series and Intermediate Series. The
Distributor has voluntarily waived a portion of its distribution fees for the
Class A and Class C shares as described under "Fund Expenses." Fee waivers and
expense subsidies will increase the Fund's total return. Any such waivers may be
terminated at any time without prior notice to shareholders. See "Performance
Information" in the Statement of Additional Information and "Fund Expenses."
 
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 and cash
of each 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 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 that event.
 
                                       31
<PAGE>
                         HOW THE FUND VALUES ITS SHARES
 
EACH 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'
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 Trustees. Securities may also be valued based on
values provided by a pricing service. See "Net Asset Value" in the Statement of
Additional Information.
 
  Each 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 declare 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 A 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 NOT INTENDED TO INDICATE FUTURE PERFORMANCE.
The yield refers to the income generated by an investment in a Series 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 a Series. The total return shows how much an investment in a
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 each 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.

                       TAXES, DIVIDENDS AND DISTRIBUTIONS
 
TAXATION OF THE FUND
 
  EACH SERIES OF THE FUND HAS QUALIFIED AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, EACH
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 A SERIES, NET TAXABLE INVESTMENT INCOME AND
CAPITAL GAINS ARE TAXABLE TO THE SERIES. See "Taxes, Dividends and
Distributions" in the Statement of Additional Information.
 
  To the extent a Series invests in taxable obligations, it will earn taxable
investment income. Also, to the extent a 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 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 each 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 each 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 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.
 
  Any gain or loss realized upon the sale or redemption of a Series' shares 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 gain if the shares were held for not more than 12 months,
gain taxable at the maximum rate of 28% if such shares were held for more than
12, but not more than 18 months, and 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
 
                                       33
<PAGE>
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 short-term capital loss. Any loss realized by a
shareholder upon the sale of shares of a Series held by the shareholder for six
months or less will be disallowed to the extent of any exempt interest dividends
received with respect to such shares and treated as long-term capital loss to
the extent of capital gains distributions received by the shareholder.
 
  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.
 
  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.
 
  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 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, a Series could be liable
for the alternative minimum tax for items of tax preference attributed to it.
 
  With the exception of the High Income Series, the Fund intends to minimize the
investment of each Series in municipal obligations of the type that will produce
items of tax preference. With respect to the High Income Series, however, it is
anticipated that a substantial portion of the Series' assets will be invested in
such obligations.
 
  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 Fund 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 a 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) 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
 
                                       34
<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 FUND 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 each 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 A 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 NAV 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 a 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 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 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.
 
                                       35
<PAGE>
  Shares of the Fund, when issued, are fully paid, nonassessable, fully
transferable and redeemable at the option of the holder. Shares are also
redeemable at the option of the Fund under certain circumstances 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 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 bear higher distribution expenses than Class A shares, the liquidation
proceeds to shareholders of those classes are likely to be lower than to Class A
shareholders and to Class Z shareholders, whose shares are not subject to any
distribution and/or service fees. The Fund'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 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.
 
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 of 1933. 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
 
  YOU MAY PURCHASE SHARES OF EACH SERIES OF THE FUND 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. Participants in programs sponsored by
Prudential Retirement Services should contact their client representative for
more information about Class Z shares. 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 (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 NAV without any sales
charge. Payments may be made by wire, check or through your brokerage account.
See "Alternative Purchase Plan" below. See also "How the Fund Values its
Shares."
 
  In order to receive that day's NAV, your order must be received before the
Fund's NAV is computed (currently 4:15 P.M., New York time). If you purchase
shares through your Dealer, the Dealer must receive your order before the Fund's
NAV is computed that day and must transmit the order to the Distributor that
same day for you to receive that day's NAV.
 
  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 the Transfer Agent or the Distributor
(Class A shares 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 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 placement of the
order.
 
  Dealers may charge their customers a separate fee for processing purchases and
redemptions. In addition, transactions in Fund shares may be subject to postage
and handling charges imposed by your Dealer. Any such charges are retained by
the Dealer and are not remitted to the Fund.
 
  PURCHASE BY WIRE. For an initial purchase of shares of the Fund by wire, you
must complete an application and 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, 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) and the name of
the Series.
 
                                       37
<PAGE>
  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 a 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, the name of the 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 FUND 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 BENEFICIAL
SALES CHARGE STRUCTURE FOR YOUR INDIVIDUAL CIRCUMSTANCES, GIVEN THE AMOUNT OF
THE PURCHASE AND THE LENGTH OF TIME YOU EXPECT TO HOLD THE SHARES AND OTHER
RELEVANT CIRCUMSTANCES (ALTERNATIVE PURCHASE PLAN).

</TABLE>
 
  The four classes of shares represent an interest in the same portfolio of
investments of each 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.
 
  Dealers, 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.
 
                                       38
<PAGE>
  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 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 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
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.
Dealers may be deemed to be underwriters, as that term is defined under the
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 its 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, Dealers or the Transfer Agent, by the following persons: (a)
officers 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 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 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 Distributor, your Dealer or the Transfer Agent.
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 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 "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.

  CLASS Z SHARES
 
  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
Prudential Securities, The Prudential Savings Bank, F.S.B. (or any affiliate)
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 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, from its own resources, based on a
percentage of the NAV of shares sold by such persons.
 
HOW TO SELL YOUR SHARES
 
  YOU CAN REDEEM YOUR SHARES OF EACH SERIES OF THE FUND AT ANY TIME FOR CASH AT
THE NAV NEXT DETERMINED AFTER THE REDEMPTION REQUEST IS RECEIVED IN PROPER FORM
(IN ACCORDANCE WITH PROCEDURES ESTABLISHED BY THE TRANSFER AGENT IN CONNECTION
WITH INVESTORS' ACCOUNTS) BY THE TRANSFER AGENT, DISTRIBUTOR, OR YOUR DEALER.
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 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
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
 
                                       41
<PAGE>
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 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 a
Series, 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 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 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 a Series of the Fund at the NAV next
determined after the order is received, which must be within 90 days after the
date of the redemption. Any CDSC paid in connection with such redemption will be
credited (in shares) to your account. If less than a full repurchase is made,
the credit will be on a PRO RATA basis. You must notify the Transfer Agent,
either directly or through the Distributor or your 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 or loss 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 reduces the current value of your Class B or Class C
shares of a Series of the Fund 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 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.
 
                                       42

  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
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), 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 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.
 
  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
 
                                       43
<PAGE>
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.
 
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. 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 NAVs, 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, 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 FUND, 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.
 
  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 NAV above the total
amount of payments for the purchase of Class B or Class C shares and (3) amounts
representing Class B or Class C shares held beyond the applicable CDSC period.
Class B and Class C shareholders must notify the Transfer Agent either directly
or through Prudential Securities, Prusec or another Dealer that they are
eligible for this special exchange privilege.
 
                                       45
<PAGE>
  Participants in any fee-based program for which the Fund is an available
option will have their Class A shares, if any, exchanged for Class Z shares when
they elect to have those assets become a part of the fee-based program. Upon
leaving the program (whether voluntarily or not), such Class Z shares (and, to
the extent provided for in the program, Class Z shares acquired through
participation in the program) will be exchanged for Class A shares at NAV.
 
  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 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 of the Fund, you can
take advantage of the following services and privileges:
 
  -AUTOMATIC REINVESTMENTS 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
your Dealer, 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 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

                        DESCRIPTION OF SECURITY RATINGS
 
MOODY'S INVESTORS SERVICE
 BOND RATINGS
 
  Aaa: Bonds that 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
edge." 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 that 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 that make the
long-term risks appear somewhat larger than in Aaa securities.
 
  A: Bonds that 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 that
suggest a susceptibility to impairment some time in the future.
 
  Baa: Bonds that 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 that 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 that are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or maintenance of other
terms of the contract over any long period of time may be small.
 
  Bonds rated within the Aa, A, Baa, Ba and B categories that Moody's believes
possess the strongest credit attributes within those categories are designated
by the symbols Aa1, A1, Baa1, Ba1 and B1.
 
  Caa: Bonds that 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 that are rated Ca represent obligations that are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.
 
  C: Bonds that 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 DEBT RATINGS
 
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations which have an original maturity not
exceeding one year.
 
  P-1: Issuers rated "Prime-1" or "P-1" (or supporting institutions) have a
superior ability for repayment of senior short-term debt obligations.
 
                                      A-1
<PAGE>
  P-2: Issuers rated "Prime-2" or "P-2" (or supporting institutions) have a
strong ability for repayment of senior short-term debt obligations.
 
  P-3: Issuers rated "Prime-3" or "P-3" (or supporting institutions) have an
acceptable ability for repayment of senior short-term debt obligations.
 
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. There is
present 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. Margins of
protection are ample although not so large as in the preceding group.
 
  MIG 3: Loans bearing the designation MIG 3 are of favorable quality. All
security elements are accounted for but there is lacking the undeniable strength
of the preceding grades.
 
  MIG 4: Loans bearing the designation MIG 4 are of adequate quality. Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.
 
STANDARD & POOR'S RATINGS GROUP
 DEBT RATINGS
 
  AAA: Debt rated AAA has the highest rating assigned by S&P. Capacity to pay
interest and repay principal is extremely strong.
 
  AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
 
  A: Debt rated A has a strong capacity to pay interest and repay principal,
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.
 
  BBB: Debt rated BBB is regarded as having an adequate capacity to pay interest
and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.
 
  BB, B, CCC, CC AND C: Debt rated BB, B, CCC, CC and C is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. BB indicates the least degree of speculation and C
the highest. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major exposures
to adverse conditions.
 
  D: Debt rated D is in payment default. The D rating category 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
 
  S&P's commercial paper ratings are current assessments of the likelihood of
timely payment of debt considered short-term in the relevant market.
 
                                      A-2
<PAGE>
  A-1: The A-1 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 the designation A-2 is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.
 
  A-3: Issues with the A-3 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 factors and market access risks
unique to notes. Notes maturing in three years or less will likely receive a
note rating. 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 characteristics are given a
plus (+) 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.

SHAREHOLDER GUIDE

SHAREHOLDER SERVICES

    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.

PRUDENTIAL MUNICIPAL SERIES FUND/MARYLAND AND MICHIGAN SERIES
PRUDENTIAL MUNICIPAL BOND FUND/INTERMEDIATE SERIES



October  , 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 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.

PLEASE READ THE ENCLOSED MATERIALS CAREFULLY FOR MORE COMPLETE INFORMATION. Your
vote is important, no matter how many shares you own. Voting your shares early
may permit your Series to avoid costly follow-up mail and telephone
solicitation. After you have reviewed the enclosed materials, please complete,
date and sign your proxy card and mail it in the enclosed postage-paid return
envelope today.

we can pass on to you) by voting through the internet or via a touch tone phone.
