Dear Sirs:

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

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

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



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

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

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

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

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

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

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

(Intermediate Series) September 18, 1998 Page 3

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     The opinions expressed herein are based upon currently applicable 
statutes and regulations and existing judicial and administrative 
interpretations.  We can provide no assurance that such statutes or 
regulations, or existing judicial or administrative interpretations thereof, 
will not be amended, revoked or modified (possibly prior to the Closing Date) 
in a manner which would affect any of our conclusions.  Finally, we note that 
this opinion is solely for the benefit of the addressees hereof in connection 
with the transaction described herein and, except as otherwise provided

Dear Sirs:

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

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

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

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

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

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

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

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

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

the Shares, in connection with the Reorganization.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Dear Sirs:

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

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

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



Prudential National Municipals Fund, Inc.

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

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

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

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

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

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

the Shares, in connection with the Reorganization.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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