    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 17, 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
<PAGE>
by National Municipals Fund of the liabilities, if any, of such Series.
Following approval by the shareholders of the Maryland or Michigan Series, Class
A shares of National Municipals Fund will be distributed to Class A, Class B and
Class C shareholders of that Series and the Series will be terminated. Following
approval by Intermediate Series' shareholders, Class A, Class B, Class C and
Class Z shares of National Municipals Fund will be distributed to Class A, Class
B, Class C and Class Z shareholders, respectively, of Intermediate Series, and
Intermediate Series will be terminated. Each Reorganization will become
effective as soon as practicable after the Meeting. Each Series' shareholders
will receive the number of full and fractional shares of National Municipals
Fund of the applicable Class equal in value (rounded to the third decimal place)
to such shareholder's corresponding shares of the Series as of the closing date.
 
REASONS FOR THE REORGANIZATIONS
 
    There are a number of similarities between each Series and National
Municipals Fund that led to consideration of the Plans. The following are among
the reasons for each Reorganization proposed by Prudential Investments Fund
Management LLC (PIFM), the Manager of each Fund:
 
    THE SERIES HAVE BEEN UNABLE TO ATTRACT SIGNIFICANT ASSETS.  Assets in each
of the Series have been steadily declining during the past several years. As of
June 30, 1998, Maryland and Michigan Series' assets were approximately
$30,950,000 and $54,413,000, respectively, with 1,357 and 2,368 shareholders,
respectively. As of June 30, 1998, the Intermediate Series assets were
approximately $38,624,000, with 1,711 shareholders. As a result, the Series have
been operated with relatively high expense ratios. Because of their size, the
Series' do not enjoy the economies of scale of National Municipals Fund. The
Manager believes the Series' situations are not likely to improve. The
Distributor of Series Fund and Municipal Bond Fund limited distribution fees
with respect to the Class A and Class C shares of the Series to no more than .10
of 1% of the average daily net asset value of the Class A shares and to no more
than .75 of 1% of the average daily net assets of the Class C shares,
respectively, for each respective Series. Although such distribution fee
limitations or waivers have been in place for some time for the Series, such
limitations or waivers are voluntary and could therefore be eliminated at any
time.
 
    NATIONAL MUNICIPALS FUND AND THE SERIES HAVE SIMILAR INVESTMENT
POLICIES.  National Municipals Fund and each Series invest primarily in
investment grade debt securities of municipal debt obligations, the investment
income from which is exempt from federal income taxes. However, shareholders of
the Maryland and Michigan Series should recognize that if the Reorganization
occurs, income from their investment in National Municipals Fund will likely be
subject to Maryland and Michigan state income taxes, as applicable. Shareholders
of each Series are advised to consult their own tax advisers regarding specific
questions as to federal, state, or local taxes. See "--Investment Objectives and
Policies" below. An additional difference is that each of the Series seeks a
high level of income consistent with capital preservation while National
Municipals Fund does not similarly seek capital preservation.
 
    NATIONAL MUNICIPALS FUND OFFERS GREATER DIVERSIFICATION OF ASSETS AND
REDUCES POTENTIAL CONCERNS RELATING TO INADEQUATE SUPPLY OF MUNICIPAL BONDS FROM
SPECIFIC STATES.  Because the Maryland and Michigan Series must each invest at
least 80% of its total assets in municipal obligations of issuers located in
Maryland or Michigan, respectively, and other obligations of qualifying issuers,
each of their portfolios are more susceptible to factors adversely affecting
issuers of such obligations than is a national municipal bond fund such as
National Municipals Fund. In addition, the State Series from time to time may
have difficulty obtaining suitable investments due to inadequate supply. A
national municipal fund such as National Municipals Fund is not similarly
constrained as to potential purchasers.
 
                                       3

    AFTER IMPLEMENTATION OF EACH PLAN, THE FORMER SHAREHOLDERS OF EACH SERIES
AND THE SHAREHOLDERS OF NATIONAL MUNICIPALS FUND MAY BENEFIT FROM REDUCED
EXPENSES RESULTING FROM GREATER ECONOMIES OF SCALE.  The Trustees of Series
Fund, the Trustees of the Municipal Bond Fund and the Directors of National
Municipals Fund believe that each Reorganization may achieve certain economies
of scale that each Series alone cannot realize because of its small size, and
that National Municipals Fund would realize the benefits of a larger asset base.
The combination of the Series and National Municipals Fund would eliminate
certain duplicate expenses, such as those incurred in connection with separate
audits and the preparation of separate financial statements for the Series and
National Municipals Fund, and reduce other expenses, because their expenses
would be spread across a larger asset base.
 
    The ratios of total expenses to average net assets for Class A, Class B,
Class C and Class Z shares of National Municipals Fund and Intermediate Series
and Class A, Class B, and Class C shares of each State Series were as follows:

(2) Net of management fee waiver and/or expense subsidy. As of September 1,
    1997, the Manager eliminated its management fee waiver (.05 of 1%) with
    respect to both National Municipal Fund and the Series.
 
(3) Before consideration of management fee waiver and/or expense subsidy.
 
*   National Municipals Fund commenced offering Class Z shares November 23,
    1998. The ratios of total expenses to average net assets for Class Z shares
    of National Municipals Fund are estimated based on expenses to have been
    incurred if Class Z shares had been in existence during the periods
    specified.
 
     AFTER IMPLEMENTATION OF THE PLANS, CERTAIN SHAREHOLDERS OF THE STATE SERIES
SHOULD BENEFIT FROM REDUCED DISTRIBUTION FEES AND SALES LOADS.  If the State
Series Plan is implemented, each Class A, Class B and Class C shareholder of the
State Series will receive the number of full and fractional Class A shares of
National Municipals Fund equal to the net asset value (rounded to the third
decimal place) of such shareholder's shares as of the closing date. Class A,
Class B and Class C shares of the State Series currently are subject to maximum
distribution fees of .10 of 1%, .50 of 1% and .75 of 1%, respectively (after
reduction). Class A shares of National Municipals Fund currently are subject to
a maximum distribution fee of .10 of 1% (after reduction). Accordingly, Class B
and Class C shareholders of the State Series should benefit from reduced
distribution fees since they will receive Class A shares in the Reorganization.
Furthermore, Class B shares of the State Series currently are subject to maximum
deferred sales loads of up to 5% and Class C shares of the State Series
currently are subject to an initial sales load of 1% and deferred sales load of
1%. If the State
 
                                       4
<PAGE>
Series Plan is implemented, such shareholders will receive Class A shares of
National Municipals Fund, which are not subject to a deferred sales load.
Therefore, Class B and Class C shareholders of the State Series should benefit
from the elimination of otherwise applicable sales loads if the State Series
Plan is approved.
 
    If the State Series Plan is implemented, Class A shareholders of the State
Series will be subject to the same distribution fee charged by National
Municipals Fund as is currently charged by the State Series (each after
reduction). Like Class A shares of the State Series, the Class A shares of
National Municipals Fund to be received in the Reorganizations by Class A
shareholders of the State Series will not be subject to any deferred sales load.
Therefore, Class A shareholders of the State Series will not be subject to any
additional distribution fees or sales loads following the Reorganizations.
 
    If the Intermediate Series Plan is implemented, each Class A, Class B, Class
C and Class Z shareholder of Intermediate Series will receive the number of full
and fractional Class A, Class B, Class C and Class Z shares of National
Municipals Fund equal to the net asset value (rounded to the third decimal
place) of such shareholder's shares as of the closing date. Class A, Class B and
Class C shares of Intermediate Series currently are subject to maximum
distribution fees (after reduction) of .10 of 1%, .50 of 1% and .75 of 1%,
respectively, which are the same maximum distribution fees (after reduction)
with respect to Class A, Class B and Class C shares of National Municipals Fund.
Class A shares of Intermediate Series and National Municipals Fund are not
subject to any deferred sales load and Class B and Class C shares of
Intermediate Series are subject to the same sales loads with respect to Class B
and Class C shares of National Municipals Fund, respectively. Furthermore, Class
Z shares of Intermediate Series and National Municipals Fund are not subject to
any distribution fees or sales loads. Therefore, Class A, Class B, Class C and
Class Z shareholders of Intermediate Series will not be subject to any
additional distribution fees or sales loads following the Reorganization.
 
    NATIONAL MUNICIPALS FUNDS HAS ACHIEVED A YIELD COMPARABLE TO THE
SERIES.  The municipal obligations held by National Municipals Fund have
historically had a higher gross yield than the obligations in the other Series'
portfolios, and National Municipals Fund has lower expense ratios than each
Series due to its appreciably larger size. The following table presents the
thirty day yield for each Series and National Municipals Fund (on a pre- and
after-state income tax basis) for the period ended June 30, 1998:

    For the reasons set forth below under "The Proposed Transaction--Reasons for
the Reorganizations Considered by the Trustees/Directors," the Directors of
National Municipals Fund, and the Trustees of Series Fund and Municipal Bond
Fund, including those Directors or Trustees who are not "interested persons"
(Independent Directors or Trustees), as that term is defined in the Investment
Company Act of 1940, as amended (Investment Company Act), have concluded that
each Reorganization would be in the best interests of the shareholders of
National Municipals Fund and the respective Series and that the interests of
shareholders of National Municipals Fund and the respective Series will not be
diluted as a result of the proposed transaction. Accordingly, the Board of
Directors of National Municipals Fund and the Trustees of Series Fund and
Municipal Bond Fund each recommend approval of the respective Plans.
 
STRUCTURE OF THE SERIES AND NATIONAL MUNICIPALS FUND
 
    Each Series is authorized to issue an unlimited number of shares of
beneficial interest, $.01 par value per share, whereas National Municipals Fund
is authorized to issue one billion shares of common stock, $.01 par value per
share. The State Series have each divided their shares into three classes,
designated Class A, Class B and Class C, each of which is currently being
offered by the respective funds. National Municipals Fund and Intermediate
Series have each divided their shares into four classes, designated Class A,
Class B, Class C and Class Z, each of which is currently being offered. Each
class of shares represents an interest in the same assets of the Maryland,
Michigan or Intermediate Series or National Municipals Fund, as the case may be,
and is identical in all respects except that (i) each class is subject to
different sales charges and/or service fees (except for Class Z shares of
National Municipals Fund and Intermediate Series, which are not subject to any
sales charges or distribution and/or service fees), (ii) each class has
exclusive voting rights on any matter submitted to shareholders that relates
solely to its arrangement and has separate voting rights on any matter submitted
to shareholders in which the interests of one class differ from the interests of
any other class, (iii) each class has a different exchange privilege, (iv) only
Class B shares have a conversion feature and (v) with respect to National
Municipals Fund and Intermediate Series, Class Z shares are offered to a limited
group of investors. The distribution systems for Class A, Class B and Class C
shares of each Fund are identical. Share certificates will be issued by National
Municipals Fund upon written request to Prudential Mutual Fund Services LLC, the
Fund's Transfer Agent. See "Shareholder Guide" in the National Municipals Fund's
Prospectus. National Municipals Fund has adopted a plan pursuant to Rule 18f-3
under the Investment Company Act permitting the issuance and sale of multiple
classes of shares. Pursuant to National Municipals Fund's Articles of
Incorporation, Series Fund's Declaration of Trust and Municipal Bond Fund's
Declaration of Trust, each Fund's Board of Directors/Trustees may authorize the
creation of additional series of shares, and classes within such series, with
such preferences, privileges, limitations and voting and dividend rights as that
Fund's Board of Directors/Trustees may determine.
 
    The Board of Directors/Trustees of each Fund may increase or decrease the
number of authorized shares of its respective Fund without approval by the
shareholders. Shares of National Municipals Fund or a Series, when issued, are
fully paid, nonassessable, fully transferable and redeemable at the option of
the holder. Shares are also redeemable at the option of each Fund under certain
circumstances. Except for the conversion feature applicable to the Class B
shares, there are no conversion, preemptive or other subscription rights. In the
event of liquidation, each share of National Municipals Fund or a Series is
entitled to its portion of all of National Municipals Fund's or the Series,
assets after all debt and expenses of that Fund have been paid. Since Class A,
Class B and Class C shares bear distribution expenses, the liquidation proceeds
to shareholders of those classes are likely to be lower than to shareholders of
Class Z shares, which are not subject to any distribution fees. None of the
Funds' shares have cumulative voting rights for the election of
Directors/Trustees.
 
                                       7
<PAGE>
    If a stock certificate is desired by a shareholder of National Municipals
Fund or a Series, it must be requested in writing for each purchase of shares.
Certificates are issued only for full shares. Shareholders who hold their shares
through Prudential Securities Incorporated (Prudential Securities) will not
receive stock certificates.
 
    It is the present intent of the Directors of National Municipals Fund and
the Trustees of Series Fund and Municipal Bond Fund not to hold annual meetings
of shareholders unless the election of Directors/Trustees is required under the
Investment Company Act, nor to hold special meetings of shareholders unless
required by the Investment Company Act or state law.
 
INVESTMENT OBJECTIVES AND POLICIES
 
    National Municipals Fund's investment objective is to seek a high level of
current income exempt from federal income taxes. There can be no assurance that
such investment objective will be achieved. National Municipals Fund seeks to
achieve its objective by investing primarily in long-term medium quality bonds
of municipalities possessing adequate but not outstanding capacities to service
their debt. While the investment adviser will not be limited by the ratings
assigned by the rating services, National Municipals Fund will be principally
invested in municipal bonds rated A and Baa by Moody's Investors Group (Moody's)
and A and BBB by Standard & Poor's Ratings Group (S&P). Unlike the Series,
preservation of capital is not an objective for National Municipals Fund. Under
normal circumstances, National Municipals Fund intends to invest substantially
all, and in any event at least 80%, of its total assets in municipal bonds and
municipal notes (E.G., tax revenue and bond anticipation notes). National
Municipals Fund may invest in variable rate securities and inverse floating rate
obligations and may engage in various hedging and return enhancing strategies,
including the purchase and sale of derivatives. These strategies include the
purchase of put options and the purchase and sale of financial futures contracts
and options thereon. See "Principal Risk Factors--Hedging and Return Enhancement
Strategies." National Municipals Fund may invest up to 15% of its net assets in
illiquid securities and may borrow an amount equal to no more than 33 1/3% of
the value of its total assets from banks for temporary, extraordinary or
emergency purposes or for the clearance of transactions.
 
    The investment objective of each of Maryland and Michigan Series is to
provide the maximum amount of income that is exempt from, respectively, Maryland
and Michigan state tax and federal income taxes as is consistent with the
preservation of capital and, in conjunction therewith, the Maryland and Michigan
Series may each invest in debt securities with the potential for capital gain.
There can be no assurance that such investment objectives will be achieved. To
achieve these objectives, the Maryland and Michigan Series each seeks to invest
at least 70% of its total assets in debt obligations rated Baa or above by
Moody's or BBB or above by S&P and may invest up to 30% of its total assets in
debt obligations rated below Baa by Moody's or BBB by S&P. The Maryland and
Michigan Series each invests primarily in municipal and local government
obligations of Maryland and Michigan, respectively, and obligations of other
qualifying issuers, such as issuers located in Puerto Rico, the Virgin Islands
and Guam, which pay income exempt, in the opinion of counsel, from the state
taxes of Michigan and Maryland, respectively, and federal income taxes.
Therefore, Maryland and Michigan Series investors who are residents of Maryland
or Michigan, respectively, receive income that is generally exempt from income
taxation by their state of residence.
 
    Intermediate Series' investment objective is to provide the maximum amount
of income that is eligible for exclusion from federal income taxes consistent
with the preservation of capital. There can be no assurance that the investment
objective will be achieved. Intermediate Series invests all of its assets in
securities rated at least BBB by S&P or Baa by Moody's and invests at least 60%
of its portfolio in securities rated A or better by Moody's or S&P.
 
                                       8
<PAGE>
    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, (PIC or the Subadviser), the Subadviser provides investment
advisory services for the management of the respective Funds. Each subadvisory
agreement provides that PIFM will reimburse the Subadviser for its reasonable
costs and expenses in providing investment advisory services. PIFM continues to
have responsibility for all investment advisory services pursuant to the
management agreements for both Funds and supervises the Subadviser's performance
of its services on behalf of each Fund.

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

    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 and the
Series and Class Z shares of National Municipals Fund and Intermediate Series.
However, if the Plans are implemented, Class A, Class B and Class C shareholders
of the State Series will receive Class A shares of National Municipals Fund,
regardless of the class of shares of the Series held prior to the
Reorganizations.

 + Pursuant to rules of the National Association of Securities Dealers, Inc.,
   the aggregate initial sales charges, deferred sales charges and asset-based
   sales charges on shares of National Municipals Fund and each Series may not
   exceed 6.25% of total gross sales, subject to certain exclusions. This 6.25%
   limitation is imposed on each class of each Fund/ Series rather than on a per
   shareholder basis. Therefore, long-term shareholders of each Fund/Series may
   pay more in total sales charges than the economic equivalent of 6.25% of such
   shareholders' investment in such shares.
 
 * Class B shares automatically convert to Class A shares approximately seven
   years after purchase.
 
    EXPENSE RATIOS.  For its fiscal year ended December 31, 1997, total expenses
stated as a percentage of average net assets of National Municipals Fund were
0.70%, 1.10% and 1.35% for Class A, Class B and Class C shares. Absent the
management fee waiver, such ratio would have been 0.73%, 1.13% and 1.38% for
Class A, Class B and Class C shares, respectively. For the six-month period
ended June 30, 1998, total expenses (annualized and unaudited), stated as a
percentage of average net assets of National Municipals Fund were 0.73%, 1.13%
and 1.38% for Class A, Class B, and Class C shares, respectively. National
Municipals Fund commenced offering Class Z shares November 23, 1998. Total
expenses (unaudited) stated as a percentage of average net assets with respect
to Class Z shares are estimated to be 0.60% (after waiver) and 0.63% (absent the
management fee waiver) for the fiscal year ended December 31, 1997 based on
expenses to have been incurred if Class Z shares had been in existence during
such fiscal year. Total expenses (annualized and unaudited) stated as a
percentage of average net assets with respect to Class Z shares are estimated to
be 0.63% for the six-month period ended June 30, 1998 based on expenses to have
been incurred if Class Z shares had been in existence during such period. For
the fiscal year ended August 31, 1998, total expenses stated as a percentage of
average net assets of each of the State Series were 1.19%, 1.58% and 1.83% for
Maryland Series and 0.92%, 1.32% and 1.57% for Michigan Series for Class A,
Class B and Class C shares, respectively. For the fiscal year ended April 30,
1998, total expenses stated as a percentage of average net assets of
Intermediate Series were 1.31%, 1.71%, 1.96% and 1.21% for Class A, Class B,
Class C and Class Z shares, respectively. Absent the management fee waiver and
expense subsidy, such ratios would have been 1.33%, 1.73%, 1.98% and 1.23% for
the Class A, Class B, Class C and Class Z shares, respectively.

    ANNUAL FUND OPERATING EXPENSES.  Following the Reorganizations, the actual
expense ratios of the combined fund are expected to be lower than those of the
State Series for the State Series' fiscal year ended August 31, 1998 and than
those of Intermediate Series for Intermediate Series' fiscal year ended April
30, 1998. Set forth below is a comparison of National Municipals Fund's and each

    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

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

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

Series arise, including any question as to an adjournment of the Meeting, the
persons named in the enclosed Proxy will vote thereon according to their best
judgment in the interests of each Series, taking into account all relevant
circumstances.
 
                            SHAREHOLDERS' PROPOSALS
 
    A shareholder proposal intended to be presented at any subsequent meeting of
the shareholders of the State Series or Intermediate Series must be received by
Series Fund or Municipal Bond Fund, respectively, a reasonable time before the
Trustees' solicitation relating to such meeting is made in order to be included
in the Series' Proxy Statement and form of Proxy relating to that meeting. The
mere submission of a proposal by a shareholder does not guarantee that such
proposal will be included in the proxy statement because certain rules under the
federal securities laws must be complied with before inclusion of the proposal
is required. In the event that the Plans are approved at this Meeting with
respect to each Series, it is not expected that there will be any future
shareholder meetings of the Series.
 
    It is the present intent of the Board of Directors of National Municipals
Fund and the Trustees of Series Fund and the Trustees of Municipal Bond Fund not
to hold annual meetings of shareholders unless the election of
Directors/Trustees is required under the Investment Company Act nor to hold
special meetings of shareholders unless required by the Investment Company Act
or state law.

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

past performance 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.

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.

(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

1.  TRANSFER OF ASSETS OF INTERMEDIATE SERIES IN EXCHANGE FOR SHARES OF NATIONAL
    MUNICIPALS FUND AND ASSUMPTION OF LIABILITIES, IF ANY, AND TERMINATION OF
    INTERMEDIATE SERIES
 
1.1  Subject to the terms and conditions herein set forth and on the basis of
the representations and warranties contained herein, Municipal Bond Fund on
behalf of Intermediate Series agrees to sell, assign, transfer and deliver the
assets of Intermediate Series, as set forth in paragraph 1.2, to National
Municipals Fund, and National Municipals Fund agrees (a) to issue and deliver to
Intermediate Series in exchange therefor the number of shares of Class A, Class
B, Class C and Class Z shares of Common Stock in National Municipals Fund
determined by dividing the net asset value of the Intermediate Series allocable
to Class A, Class B, Class C and Class Z shares of beneficial interest (computed
in the manner and as of the time and date set forth in paragraph 2.1) by the net
asset value allocable to a share of National Municipals Fund Class A, Class B,
Class C and Class Z shares of Common Stock (computed in the manner and as of the
time and date set forth in paragraph 2.2); and (b) to assume all of Intermediate
Series' liabilities, if any, as set forth in paragraph 1.3. Such transactions
shall take place at the closing provided for in paragraph 3 (Closing).
 
1.2  The assets of Intermediate Series to be acquired by National Municipals
Fund shall include without limitation all cash, cash equivalents, securities,
receivables (including interest and dividends receivable) and other property of
any kind owned by such Series and any deferred or prepaid expenses shown as
assets on the
 
                                     B-1(A)
<PAGE>
books of such Series on the closing date provided in paragraph 3 (Closing Date).
National Municipals Fund has no plan or intent to sell or otherwise dispose of
any assets of Intermediate Series, other than in the ordinary course of
business.
 
1.3  Except as otherwise provided herein, National Municipals Fund will assume
all debts, liabilities, obligations and duties of Intermediate Series of
whatever kind or nature, whether absolute, accrued, contingent or otherwise,
whether or not determinable as of the Closing Date and whether or not
specifically referred to in this Agreement; provided, however, that Intermediate
Series agrees to utilize its best efforts to cause such Series to discharge all
of the known debts, liabilities, obligations and duties of such Series prior to
the Closing Date.
 
1.4  On or immediately prior to the Closing Date, Intermediate Series will
declare and pay to its shareholders of record dividends and/or other
distributions so that it will have distributed substantially all (and in any
event not less than ninety-eight percent) of each of such Series' investment
company taxable income (computed without regard to any deduction for dividends
paid), net tax-exempt interest income, if any, and realized net capital gains,
if any, for all taxable years through its termination.
 
1.5  On a date (Termination Date), as soon after the Closing Date as is
conveniently practicable, but in any event within 30 days of the Closing Date,
Intermediate Series will distribute PRO RATA to its Class A, Class B, Class C
and Class Z shareholders of record, determined as of the close of business on
the Closing Date, the Class A, Class B, Class C and Class Z shares of National
Municipals Fund received by Intermediate Series pursuant to paragraph 1.1 in
exchange for their interest in such Series, and Municipal Bond Fund will file
with the Secretary of State of The Commonwealth of Massachusetts a Certificate
of Termination terminating Intermediate Series. Such distribution will be
accomplished by opening accounts on the books of National Municipals Fund in the
names of Intermediate Series' shareholders and transferring thereto the shares
credited to the account of Intermediate Series on the books of National
Municipals Fund. Each account opened shall be credited with the respective PRO
RATA number of National Municipals Fund Class A, Class B, Class C and Class Z
shares due such Series' Class A, Class B, Class C and Class Z shareholders,
respectively. Fractional shares of National Municipals Fund shall be rounded to
the third decimal place.
 
1.6  National Municipals Fund shall not issue certificates representing its
shares in connection with such exchange. With respect to any Intermediate Series
shareholder holding Intermediate Series receipts for shares of beneficial
interest as of the Closing Date, until National Municipals Fund is notified by
Municipal Bond Fund's transfer agent that such shareholder has surrendered his
or her outstanding Series receipts for shares of beneficial interest or, in the
event of lost, stolen or destroyed receipts for shares of beneficial interest,
posted adequate bond or submitted a lost certificate form, as the case may be,
National Municipals Fund will not permit such shareholder to (1) receive
dividends or other distributions on National Municipals Fund shares in cash
(although such dividends and distributions shall be credited to the account of
such shareholder established on National Municipals Fund's books pursuant to
paragraph 1.5, as provided in the next sentence), (2) exchange National
Municipals Fund shares credited to such shareholder's account for shares of
other Prudential Mutual Funds, or (3) pledge or redeem such shares. In the event
that a shareholder is not permitted to receive dividends or other distributions
on National Municipals Fund shares in cash as provided in the preceding
sentence, National Municipals Fund shall pay such dividends or other
distributions in additional National Municipals Fund shares, notwithstanding any
election such shareholder shall have made previously with respect to the payment
of dividends or other distributions on shares of Intermediate Series.
Intermediate Series will, at its expense, request its shareholders to surrender
their outstanding Intermediate Series receipts for shares of beneficial
interest, post adequate bond or submit a lost certificate form, as the case may
be.

the National Municipals Fund's transfer agent. Shares of National Municipals
Fund will be issued in the manner described in National Municipals Fund's

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.

    by Intermediate Series' shareholders will include the period during which

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

    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

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

                              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.

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

  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:

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

Waiver of the Contingent Deferred Sales Charge-Class B Shares
 
  The contingent deferred sales charge (CDSC) is waived under circumstances 
described in the Prospectus. See "Shareholder Guide-How to Sell Your

  The Transfer Agent reserves the right to request such additional documents as 
it may deem appropriate. 
 
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

                                   APPENDIX I
                   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.

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.

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

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

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

  Set forth below is historical performance data relating to various sectors of 
the fixed-income securities markets. The chart shows the historical total 
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds, 
U.S. high yield bonds and world government bonds on an annual basis from 1987 
to September 1996. The total returns of the indices include accrued interest, 
plus the price changes (gains or losses) of the underlying securities during 
the period mentioned. The data is provided to illustrate the varying historical 
total returns and investors should not consider this performance data as an 
indication of the future performance of the Fund or of any sector in which the

  All information relies on data obtained from statistical services, reports 
and other services believed by the Manager to be reliable. Such information has 
not been verified. The figures do not reflect the operating expenses and fees 
of a mutual fund. See "Fund Expenses" in the prospectus. The net effect of the 
deduction of the operating expenses of a mutual fund on these historical total 
returns, including the compounded effect over time, could be substantial.

  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 
  to International Stock Series, a portfolio of Prudential World Fund, Inc.

  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

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.

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.

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

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

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

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

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

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

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

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

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

Notes to Financial Statements                    PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
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.

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.

THAT THIS TRANSACTION SERVES YOUR INTERESTS IN THE FOLLOWING WAYS:
 
SIMILAR STRATEGIES--GREATER FLEXIBILITY
 
     The Funds' investment objectives and strategies, while not identical, are
     similar. Each invests primarily in investment grade, tax-exempt municipal
     bonds. While Maryland and Michigan Series seek to provide income exempt
     from federal and Maryland and Michigan state income taxes, respectively,
     Prudential National Municipals Fund seeks income exempt from only federal
     income taxes. Increasingly, single state series have had difficulty finding
     attractive issues due to a shrinking municipal bond supply--making
     portfolio diversification a challenge. In contrast, Prudential National
     Municipals Fund is nationally diversified, enabling it to invest in a wider
     range of municipal bond investment opportunities.
 
EXPENSE LEVELS
 
     The Series have relatively few assets and have not been able to attract new
     assets. They operated with relatively high expense ratios before voluntary
     management fee waivers, which were discontinued by the Manager as of
     September 1, 1997.
 
POTENTIAL FOR HIGHER INCOME GENERALLY EXEMPT INCOME TAXES
 
     The municipal obligations held by National Municipals Fund have
     historically had a higher gross yield than the obligations in the Series'
     portfolios and National Municipals Fund has lower expense ratios than the
     Series due to its appreciably larger size.
 
PRUDENTIAL NATIONAL MUNICIPALS FUND'S investment objective is to seek a high
level of current income exempt from federal income taxes. The Fund seeks to
achieve this objective by investing in a broadly diversified portfolio of
municipal bonds issued from across the country. Portfolio manager Peter
Allegrini has over 19 years of investment experience.
