Ladies and Gentlemen:

          We have acted as counsel for Prudential National Municipals Fund, 
Inc. (the "Fund") in connection with the proposed acquisition by the Fund of 
(a) all of the assets of Maryland and Michigan Series (collectively, the 
"State Series"), each a series of Prudential Municipal Series Fund ("Series 
Fund"), in exchange solely for Class A shares of the Fund and the Fund's 
assumption of all of the liabilities, if any, of the State Series and (b) all 
of the assets of Intermediate Series ("Intermediate Series") of Prudential 
Municipal Bond Fund ("Bond Fund"), in exchange for Class A, Class B and Class 
C shares of the Fund and the Fund's assumption of all the liabilities, if 
any, of Intermediate Series (the "Reorganizations," and each a 
"Reorganization").  This opinion is furnished in connection with the Fund's 
Registration Statement on Form N-14 under the Securities Act of 1933, as 
amended (the "Registration Statement"), relating to Class A, Class B and 
Class C shares of common stock, par value $0.01 per share, of the Fund (the 
"Shares"), to be issued in the Reorganizations.

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

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

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

Ladies and Gentlemen:

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

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

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

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

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

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

                                 Very truly yours,

                                 /s/ Piper & Marbury LLP
