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

                                APRIL 21, 1999


                                 INTRODUCTION

     This Proxy Statement is furnished in connection with the  solicitation of
proxies on behalf of the Boards of  Directors  or  Trustees  (hereinafter  the
"Directors") of the above-listed funds (each a "Fund" and,  collectively,  the
"Funds"),  to be voted at the 1999 Annual Meeting of Stockholders of each Fund
(the "Meeting"),  to be held at the offices of Merrill Lynch Asset Management,
L.P. ("MLAM"), 800 Scudders Mill Road,  Plainsboro,  New Jersey, on Wednesday,
April 21,  1999 at the time  specified  in Exhibit A hereto.  The  approximate
mailing date of this Proxy Statement is March , 1999.

     Each  Fund  is  organized   either  as  a  Maryland   corporation   or  a
Massachusetts  business trust. In each jurisdiction,  nomenclature varies. For
ease and clarity of  presentation,  throughout the proxy  statement  shares of
common stock or beneficial interest of a Fund are referred to as "Shares," the
outstanding  Shares and auction market  preferred stock ("AMPS") of a Fund are
referred to collectively as the "Capital Stock," holders of Shares or AMPS are
referred to as  "stockholders,"  the Board of Directors or Trustees of each of
the Funds is referred to as the  "Board,"  the  directors  or trustees of each
Fund are referred to as "Board  members," the investment  adviser of each Fund
is referred to as the  "Investment  Adviser" or "FAM" and each Fund's Articles
of  Incorporation  or  Declaration  of Trust is referred to as its  "charter."
Unless  otherwise  indicated,  MLAM and Fund Asset Management L.P. ("FAM") are
together referred to as "MLAM."

     All properly executed proxies received prior to the Meeting will be voted
at the Meeting in accordance with the instructions marked thereon or otherwise
as provided therein.  Unless instructions to the contrary are marked,  proxies
will be voted FOR the election of the Board members,  FOR the  ratification of
the selection of independent  auditors to serve for that Fund's current fiscal
year and FOR the amendment to the Articles  Supplementary  or  Certificate  of
Designation of the applicable Fund. Any proxy may be revoked at any time prior
to the  exercise  thereof by giving  written  notice to the  Secretary  of the
applicable Fund at that Fund's address  indicated above or by voting in person
at the Meeting.

     The Board of each Fund has fixed the close of business  on  February  24,
1999  as the  record  date  (the  "Record  Date")  for  the  determination  of
stockholders  entitled  to  notice  of and to vote at the  Meeting  and at any
adjournment  thereof.  Stockholders on the Record Date will be entitled to one
vote for each share held, with no shares having  cumulative  voting rights. As
of the Record  Date,  each Fund had  outstanding  the number of Shares and the
number of shares of AMPS  indicated  in  Exhibit A. To the  knowledge  of each
Fund,  as of the Record Date, no person is the  beneficial  owner of more than
five percent of its outstanding Shares or AMPS at such date.

     The Board of each Fund knows of no business  other than that mentioned in
Items  1,  2 and 3 of the  Notice  of  Meeting  that  will  be  presented  for
consideration at the Meeting. If any other matter is properly presented, it is
the intention of the persons named in the enclosed proxy to vote in accordance
with their best judgment.

                       ITEM 1. ELECTION OF BOARD MEMBERS

     At the Meetings,  the Board members of each Fund will be elected to serve
until the next Annual  Meeting of  Stockholders  for such Fund and until their
successors  are  elected  and  qualified.  It is  intended  that all  properly
executed proxies will be voted (unless such authority has been withheld in the
proxy) as follows:

          (1) All  proxies of the  holders  of AMPS,  voting  separately  as a
     class,  in favor of the two (2) persons  designated in Exhibit A as Board
     members to be elected by holders of AMPS; and

          (2) All proxies of the holders of Shares and AMPS,  voting  together
     as a single class, in favor of the five (5) persons designated in Exhibit
     A as Board members to be elected by holders of shares and AMPS.

     The Board of each Fund knows of no reason why any of these  nominees will
be unable to serve, but in the event of any such  unavailability,  the proxies
received  will be voted for such  substitute  nominee or nominees as the Board
for such Fund may recommend.

     Certain   information   concerning  the  nominees  is  set  forth  below.

</TABLE>


     COMMITTEE AND BOARD MEETINGS. The Board of each Fund has a standing Audit
Committee, which consists of Board members who are not "interested persons" of
the Fund within the  meaning of the  Investment  Company  Act.  The  principal
purpose of the Audit  Committee  is to review  the scope of the  annual  audit
conducted  by the  Fund's  independent  auditors  and the  evaluation  by such
auditors of the accounting procedures followed by the Fund. The non-interested
Board  members  have  retained  independent  legal  counsel to assist  them in
connection with these duties. No Fund's Board has a nominating committee.

     During each Fund's last fiscal  year,  each of the Board  members then in
office  attended at least 75% of the aggregate of the total number of meetings
of the Board held during the fiscal year and, if a member, of the total number
of meetings of the Audit Committee held during the period for which he served.

     COMPLIANCE  WITH SECTION  16(A) OF THE  SECURITIES  EXCHANGE ACT OF 1934.
Section  16(a)  of the  Securities  Exchange  Act of  1934,  as  amended  (the
"Exchange Act"),  requires the officers and directors of each Fund and persons
who own more than ten  percent  of a  registered  class of the  Fund's  equity
securities,  to file reports of ownership and changes in ownership on Forms 3,
4 and 5 with the Securities and Exchange  Commission  ("SEC") and the New York
Stock Exchange.  Officers, directors and greater than ten percent stockholders
are required by SEC  regulations  to furnish the Fund with copies of all Forms
3, 4 and 5 they file.

     Based  solely on each  Fund's  review of the  copies of such  forms,  and
amendments thereto,  furnished to it during or with respect to its most recent
fiscal year, and written  representations  from certain reporting persons that
they were not required to file Form 5 with  respect to the most recent  fiscal
year, each Fund believes that all of its officers, directors, greater than ten
percent  beneficial  owners  and other  persons  subject  to Section 16 of the
Exchange  Act  because of the  requirements  of  Section 30 of the  Investment
Company  Act,  (I.E.,  any  advisory  board  member,   investment  adviser  or
affiliated  person of the Fund's investment  adviser),  have complied with all
filing requirements applicable to them with respect to transactions during the
Fund's  most  recent   fiscal  year,   except  that  Michael  J.   Hennewinkel
inadvertently  made a late Form 3 filing  reporting  his  election as a Senior
Vice President of FAM,  which report  indicated that owned no shares of any of
the Funds.

     INTERESTED  PERSONS.  Each Fund considers Mr. Zeikel to be an "interested
person" of the Fund within the meaning of Section  2(a)(19) of the  Investment
Company Act because of the positions he holds with FAM and its affiliates. Mr.
Zeikel is the President of each Fund and the Chairman of FAM and MLAM.

     COMPENSATION OF BOARD MEMBERS.  FAM, the investment adviser of each Fund,
pays all compensation to all officers of the Fund and all Board members of the
Fund who are affiliated with ML & Co. or its subsidiaries. Each Fund pays each
Board member not affiliated with FAM (each a "non-affiliated Board member") an
annual fee plus a fee for each meeting attended,  and each Fund also pays each
member of its Audit  Committee,  which  consists of all of the  non-affiliated
Board members,  an annual fee plus a fee for each meeting  attended,  together
with such  non-affiliated  Board member's  out-of-pocket  expenses relating to
attendance  at such  meetings.  Information  with respect to fees and expenses
paid to the  non-affiliated  Directors for each Fund's most recently completed
fiscal year is set forth in Exhibit A.

     OFFICERS OF THE FUNDS. Information regarding the officers of each Fund is
set forth in Exhibit A. Officers of the Funds are elected and appointed by the
Board  and hold  office  until  they  resign,  are  removed  or are  otherwise
disqualified to serve.

     STOCK  OWNERSHIP.  At the Record Date,  the Board members and officers of
each Fund as a group owned an  aggregate  of less than 1% of the Shares of the
Fund  outstanding at such date and owned none of the AMPS  outstanding at such
date. At such date,  Mr.  Zeikel,  an officer and a Board member of each Fund,
and the other  officers of each Fund owned an aggregate of less than 1% of the
outstanding shares of common stock of ML & Co.

           ITEM 2. RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Board of each Fund (other than  MuniVest  New Jersey  Fund,  Inc.  and
MuniYield  Michigan  Insured  Fund,  Inc.),  including  a majority of the Board
members who are not  interested  persons of the Fund,  has selected the firm of
Deloitte & Touche LLP ("D&T"),  independent  auditors, to examine the financial
statements of the Fund for the current fiscal year. No Fund knows of any direct
or  indirect  financial  interest of such  auditors in the Fund.  The Boards of
MuniVest New Jersey Fund,  Inc. and  MuniYield  Michigan  Insured  Fund,  Inc.,
including a majority of the Board  members  who are not  interested  persons of
MuniVest New Jersey Fund, Inc. or MuniYield  Michigan  Insured Fund, Inc., have
selected  Ernst & Young LLP  ("E&Y"),  independent  auditors,  to  examine  the
financial  statements of MuniVest New Jersey Fund, Inc. and MuniYield  Michigan
Insured Fund, Inc. for the current fiscal year. Such  appointment is subject to
ratification or rejection by the  stockholders of each Fund.  Unless a contrary
specification  is  made,  the  accompanying  proxy  will be  voted  in favor of
ratifying the selection of such auditors.

     D&T acts as independent auditor for each of the Funds, except MuniVest New
Jersey Fund, Inc. and MuniYield Michigan Insured Fund, Inc., for which E&Y acts
as independent  auditor. D&T also acts as independent auditors for ML & Co. and
all of its subsidiaries and for most other investment  companies advised by FAM
or MLAM. E&Y also acts as independent  auditors for other investment  companies
advised by FAM or MLAM.  The fees  received by the  independent  auditors  from
these other entities are  substantially  greater,  in the  aggregate,  than the
total fees received by the independent  auditors from each applicable Fund. The
Board of each Fund  considered  the fact that (i) D&T has been  retained as the
independent  auditors for ML & Co. and he other  entities  described  above and
(ii) E&Y has been  retained as the  independent  auditors for other  investment
companies  advised by FAM or MLAM in its evaluation of the  independence of the
independent auditors with respect to the Fund.

     Representatives of D&T and E&Y are expected to be present at the Meetings
and will have the  opportunity  to make a  statement  if they so desire and to
respond to questions from stockholders.

             ITEM 3. PROPOSED AMENDMENT TO ARTICLES SUPPLEMENTARY
                         OR CERTIFICATE OF DESIGNATION

     At  meetings  held  February  3,  1999,  the  Board of each of the  Funds
approved  amendments  to  Section  5(c)  of  the  Articles   Supplementary  or
Certificate  of  Designation,  as  applicable,  of  that  Fund.  The  proposed
amendment  of Section  5(c) will  affect  issued  and  outstanding  AMPS.  The
proposed  amendment is described  below and a form of amended  Section 5(c) is
attached to this Proxy Statement as Exhibit B-1 for the Maryland  corporations
and as Exhibit B-2 for the  Massachusetts  business trusts.  Information about
each Fund's  jurisdiction of organization  and its Articles  Supplementary  or
Certificate  of  Designation  is included in Exhibit A. The Board of each Fund
has  declared  the  amendment  advisable  and has  directed  that the proposed
amendments be submitted to the  stockholders of each of the Funds for approval
at the  Meeting.  The  Board  recommends  that the  stockholders  of each Fund
approve the  proposed  amendments  to that Fund's  Articles  Supplementary  or
Certificate of Designation.

     Currently,  the Articles  Supplementary  or Certificate of Designation of
each Fund require the approval of a majority of a Fund's  outstanding  AMPS in
order to issue any additional shares of AMPS or any other preferred stock. The
proposed  amendment  would delete this  requirement and permit each Fund, upon
Board approval, to issue additional shares of preferred stock, including AMPS,
without obtaining stockholder approval.

     The  proposed  amendment  provides  the Board and each Fund with  greater
flexibility.  The  proposed  amendment  permits  the  Board  members  to issue
additional  AMPS in order to maintain each Fund's  targeted level of financial
leverage  without the time delays and costs involved with seeking  stockholder
approval each time a Fund wishes to issue additional AMPS.

     The  issuance of  additional  AMPS may  provide  holders of Shares with a
potentially higher yield. The use of leverage, however, involves certain risks
for holders of Shares, including higher volatility of both the net asset value
and the market  value of the Shares.  Leverage  also creates the risk that the
investment  return on the  Fund's  Shares  will be  reduced  to the extent the
dividends paid on preferred  stock and other  expenses of the preferred  stock
exceed  the  income  earned  by the  Fund on its  investments.  If the Fund is
liquidated,  preferred  stockholders  will be entitled to receive  liquidating
distributions before any distribution is made to holders of Shares.

     The fee  paid to the  Investment  Adviser  for  investment  advisory  and
management  services  is  based  on the  Fund's  average  weekly  net  assets,
including assets acquired from the sale of preferred stock. Therefore, the fee
paid to the  Investment  Adviser will  increase as a result of any issuance of
additional AMPS or other preferred stock.

     Any issuance of additional shares of preferred stock by a Fund must be in
compliance  with the 200%  asset  coverage  requirement  of  Section 18 of the
Investment  Company  Act.  Also,  the  Funds  currently  anticipate  that  any
additional  shares of preferred stock to be issued would also be AMPS and that
any such  AMPS  would be rated by  nationally  recognized  statistical  rating
organizations  ("NRSROs") as are all currently  outstanding AMPS. These NRSROs
in  rating  the   additional   AMPS  will  impose  their  own  asset  coverage
requirements on the additional AMPS.

     If  additional  AMPS or other shares of  preferred  stock are issued by a
Fund,  except as indicated below and as otherwise  required by applicable law,
holders of shares of any newly issued AMPS or other  preferred stock will have
equal voting rights with outstanding  Shares and AMPS (one vote per share) and
will vote  together  with holders of  outstanding  Shares and AMPS as a single
class.

     In  connection  with the election of a Fund's Board  members,  holders of
shares of any newly issued AMPS or other  preferred  stock and the outstanding
AMPS,  voting together as a separate  class,  will be entitled to elect two of
the Fund's Board members,  and the remaining  Board members will be elected by
all holders of Capital Stock. If at any time dividends on shares of the Fund's
preferred  stock  shall be  unpaid  in an  amount  equal  to two  full  years'
dividends  thereon,  the holders of any newly  issued AMPS or other  preferred
stock and the outstanding  AMPS,  voting together as a separate class, will be
entitled to elect a majority of the Fund's Board  members  until all dividends
in default  have been paid or declared and set apart for  payment.  Also,  the
affirmative  vote of the holders of any newly  issued AMPS or other  preferred
stock and the outstanding  AMPS,  voting together as a separate class, will be
required to approve any plan of reorganization adversely affecting such shares
or any action  requiring a vote of security holders under Section 13(a) of the
Investment  Company Act, including any vote to convert the Fund to an open-end
investment company or to change the Fund's fundamental investment policies.

     The Board of each  Fund  recommends  that the  stockholders  approve  the
proposed   amendment  to  the  Articles   Supplementary   or   Certificate  of
Designation.

                            ADDITIONAL INFORMATION

     The expenses of preparation, printing and mailing of the enclosed form of
proxy and  accompanying  Notice and Proxy Statement will be borne by the Funds
in proportion to their respective net assets.  The Funds will reimburse banks,
brokers  and  others  for  their  reasonable   expenses  in  forwarding  proxy
solicitation material to the beneficial owners of the shares of the Funds. The
Funds may also hire proxy solicitors at their own expense.

     In order to obtain the necessary  quorum at the Meeting (i.e., a majority
of the shares of each class of securities of each Fund entitled to vote at the
Meeting,  present in person or by proxy),  supplementary  solicitation  may be
made by mail,  telephone,  telegraph or personal  interview by officers of the
Fund. It is anticipated that the cost of such supplementary  solicitation,  if
any, will be nominal.

     All shares represented by properly executed proxies,  unless such proxies
have previously been revoked, will be voted at the Meetings in accordance with
the directions on the proxies;  if no direction is indicated,  the shares will
be voted  "FOR" the Board  member  nominees,  "FOR"  the  ratification  of the
independent auditors and "FOR" the amendment to the Articles  Supplementary or
Certificate of Designation.

     With  respect to Item 1.  "Election  of Board  Members,"  holders of AMPS,
voting  separately  as a class,  are  entitled  to elect two Board  members and
holders of Capital Stock,  voting  together as a single class,  are entitled to
elect the  remaining  Board  members.  Assuming a quorum is present,  (A) [with
respect to Maryland  corporations]  (i) election of the two Board members to be
elected by the holders of AMPS,  voting  separately as a class,  will require a
plurality of all votes cast by the holders of AMPS,  represented at the Meeting
and entitled to vote;  and (ii)  election of the  remaining  Board members will
require a plurality  of all of the votes cast by the  holders of Capital  Stock
represented  at the Meeting and entitled to vote,  voting  together as a single
class; (B) [with respect to Massachusetts  business trusts] (i) election of the
two Board members to be elected by the holders of AMPS,  voting separately as a
class,  will require the affirmative  vote of a majority of the AMPS present at
the  Meeting in person or by proxy and (ii)  election  of the  remaining  Board
members  will  require  the  affirmative  vote of a  majority  of the shares of
Capital Stock present at the Meeting in person or by proxy,  voting together as
a single class.

     With  respect  to Item  2.  "Ratification  of  Selection  of  Independent
Auditors,"  assuming  a quorum  is  present  (A)  [with  respect  to  Maryland
corporations]  approval will require the affirmative vote of a majority of the
votes  cast by the  holders  of shares of  Capital  Stock  represented  at the
Meeting and entitled to vote, voting together as a single class; and (B) [with
respect  to   Massachusetts   business   trusts]  approval  will  require  the
affirmative  vote of a majority of the shares of Capital  Stock present at the
meeting in person or by proxy, voting together as a single class.

     With respect to Item 3. "Proposed Amendments To Articles Supplementary or
Certificate of Designation,"  assuming a quorum is present,  (A) [with respect
to  the  Maryland   corporations]  approval  of  amendment  of  each  Articles
Supplementary   will  require  the   affirmative   vote  of  (i)  the  holders
representing  a majority  of the  outstanding  shares of Capital  Stock of the
relevant  Fund,  voting  together  as a single  class,  and  (ii) the  holders
representing a majority of the outstanding  AMPS of all series of the relevant
Funds,   voting  together  as  a  single  class;  and  (B)  [with  respect  to
Massachusetts  business  trusts]  approval of amendment of each Certificate of
Designation  will require the affirmative vote of (i) a majority of the shares
of Capital Stock of the relevant  Funds present at the Meeting in person or by
proxy,  voting  together as a single  class and (ii) the  affirmative  vote of
two-thirds of the AMPS outstanding and entitled to vote,  voting together as a
single class.

     Broker-dealer  firms,  including  Merrill Lynch,  Pierce,  Fenner & Smith
Incorporated ("MLPF&S"),  holding shares of each Fund in "street name" for the
benefit of their  customers and clients will request the  instructions of such
customers  and  clients  on how to vote their  shares on each Item  before the
Meeting.  The Funds  understand  that,  under the rules of the New York  Stock
Exchange,  such  broker-dealer  firms  may,  without  instructions  from their
customers and clients,  grant  authority to the proxies  designated to vote on
the election of Board  members (Item 1) and  ratification  of the selection of
independent  auditors (Item 2) if no instructions  have been received prior to
the  date   specified  in  the   broker-dealer   firm's   request  for  voting
instructions.  Broker-dealer forms, including MLPF&S, will not be permitted to
grant  voting  authority  without  instructions  with  respect to amending the
Articles  Supplementary or Certificate of Designation (Item 3). The Funds will
include shares held of record by broker-dealers as to which such authority has
been  granted in their  tabulation  of the total  number of votes  present for
purposes of determining  whether the necessary quorum of stockholders  exists.
Proxies  that are  returned  to the Fund but that are marked  "abstain"  or on
which  a  broker-dealer   has  declined  to  vote  on  any  proposal  ("broker
non-votes")  will be counted as present for  purposes of a quorum.  MLPF&S has
advised  the Fund that it intends to vote shares held in its name for which no
instructions  are received,  except as limited by agreement or applicable law,
on Items 1 and 2 in the same  proportion as the votes received from beneficial
owners of those shares for which  instructions have been received,  whether or
not held in nominee name. Abstentions and broker non-votes will not be counted
as votes cast. Abstentions and broker non-votes,  therefore,  will not have an
effect on the vote on Item 1 or Item 2 (in the case of Maryland corporations);
however, abstentions and broker  non-votes will have the same effect as a vote
against  Item 3 (in the case of Maryland  corporations)  and as a vote against
Item 1, Item 2 and Item 3 (in the case of Massachusetts business trusts).

     Management  knows of no other  matters  to be  presented  at the  special
meeting.  However, if other matters are presented for a vote at the meeting or
any adjournments  thereof,  the proxy holders will vote the shares represented
by properly executed proxies according to their judgment on those matters.

               PROPOSED AMENDMENT TO ARTICLES SUPPLEMENTARY OF:


                    MUNIYIELD NEW JERSEY INSURED FUND, INC.
                        MUNIVEST NEW JERSEY FUND, INC.
                     MUNIYIELD MICHIGAN INSURED FUND, INC.
                     MUNIVEST MICHIGAN INSURED FUND, INC.

     SECTION 5(C) OF THE ARTICLES  SUPPLEMENTARY IS REVISED TO READ AS FOLLOWS
(THE  UNDERLINING   INDICATES  LANGUAGE  ADDED;   BRACKETS  INDICATE  LANGUAGE
DELETED):

     Right to Vote with  Respect  to  Certain  Other  Matters.  So long as any
shares  of AMPS are  outstanding,  the  Corporation  shall  not,  without  the
affirmative  vote of the holders of a majority of the shares of the  Preferred
Stock  Outstanding at the time, voting separately as one class: (i) authorize,
create or issue [, or increase the  authorized or issued amount of,] any class
or series of stock  ranking  prior to the AMPS or [on a parity with] any other
series of  Preferred  Stock  with  respect  to  payment  of  dividends  or the
distribution of assets on liquidation,  [or increase the authorized  amount of
AMPS or any  other  Preferred  Stock]  or (ii)  amend,  alter  or  repeal  the
provisions of the Charter,  whether by merger,  consolidation or otherwise, so
as to adversely  affect any of the contract rights  expressly set forth in the
Charter  of  holders of shares of AMPS or any other  Preferred  Stock.  To the
extent  permitted  under  the 1940 Act,  in the event  shares of more than one
series of AMPS are outstanding,  the Corporation  shall not approve any of the
actions set forth in clause (i) or (ii) which  adversely  affects the contract
rights expressly set forth in the Charter of a Holder of shares of a series of
AMPS  differently than those of a Holder of shares of any other series of AMPS
without  the  affirmative  vote of the  holders of at least a majority  of the
shares of AMPS of each series adversely  affected and outstanding at such time
(each such  adversely  affected  series  voting  separately  as a class).  The
Corporation  shall notify  Moody's and S&P ten Business Days prior to any such
vote described in clause (i) or (ii).  Unless a higher  percentage is provided
for under the Charter,  the  affirmative  vote of the holders of a majority of
the outstanding shares of Preferred Stock,  including AMPS, voting together as
a single  class,  will be  required  to  approve  any  plan of  reorganization
(including  bankruptcy  proceedings)  adversely  affecting  such shares or any
action  requiring a vote of security  holders  under Section 13(a) of the 1940
Act. The class vote of holders of shares of Preferred  Stock,  including AMPS,
described  above will in each case be in  addition  to a separate  vote of the
requisite  percentage of shares of Common Stock and shares of Preferred Stock,
including  AMPS,  voting together as a single class necessary to authorize the
action in question.

             PROPOSED AMENDMENT TO CERTIFICATE OF DESIGNATION OF:

                             MUNIVEST FLORIDA FUND
                        MUNIYIELD FLORIDA INSURED FUND

     SECTION  5(C) OF THE  CERTIFICATE  OF  DESIGNATION  IS REVISED TO READ AS
FOLLOWS (THE UNDERLINING  INDICATES LANGUAGE ADDED; BRACKETS INDICATE LANGUAGE
DELETED):

     Right to Vote with  Respect  to  Certain  Other  Matters.  So long as any
shares of AMPS are  outstanding,  the Trust shall not, without the affirmative
vote of the holders of a majority of the Preferred  Shares  Outstanding at the
time,  voting  separately as one class:  (i) authorize,  create or issue [, or
increase the  authorized  or issued  amount of,] any class or series of shares
ranking  prior to the AMPS or [on a parity with] any other series of Preferred
Shares with respect to payment of dividends or the  distribution  of assets on
liquidation, [or increase the authorized amount of AMPS or any other Preferred
Shares]  provided  however  that the Board of  Trustees,  without  the vote or
consent of the holders of AMPS,  may from time to time  increase the amount of
authorized  and  issued  shares of any  series of AMPS or any other  series of
Preferred  Shares ranking on a parity with AMPS with respect to the payment of
dividends,  or the  distribution  of assets upon  dissolution,  liquidation or
winding up the affairs of the Trust then outstanding and issue such shares, or
(ii) amend,  alter or repeal the  provisions  of the  Declaration,  whether by
merger,  consolidation  or  otherwise,  so as to  adversely  affect any of the
contract rights expressly set forth in the Declaration of holders of shares of
AMPS or any other Preferred  Shares provided however that the amendment of the
Declaration  solely to  incorporate an increase in the amount of any series of
AMPS or Preferred  Shares and the terms of issuance  thereof,  as permitted by
subsection (i) of this  paragraph (c) shall not be deemed to adversely  affect
any of the contract  rights  expressly set forth in the Declaration of holders
of shares of AMPS or any other Preferred Shares. To the extent permitted under
the  1940  Act,  in the  event  shares  of more  than one  series  of AMPS are
outstanding,  the Trust  shall not  approve  any of the  actions  set forth in
clause (i) or (ii) which adversely  affects the contract rights  expressly set
forth in the Declaration of a Holder of shares of a series of AMPS differently
than  those of a Holder  of shares of any  other  series of AMPS  without  the
affirmative  vote of the  holders of at least a majority of the shares of AMPS
of each series  adversely  affected  and  outstanding  at such time (each such
adversely  affected  series  voting  separately  as a class).  The Trust shall
notify  Moody's and S&P ten Business Days prior to any such vote  described in
clause  (i) or (ii).  Unless a higher  percentage  is  provided  for under the
Declaration,  the  affirmative  vote  of  the  holders  of a  majority  of the
outstanding  Preferred  Shares,  including  AMPS,  voting together as a single
class,  will be  required  to approve  any plan of  reorganization  (including
bankruptcy   proceedings)  adversely  affecting  such  shares  or  any  action
requiring a vote of security  holders under Section 13(a) of the 1940 Act. The
class vote of holders of Preferred  Shares,  including  AMPS,  described above
will  in  each  case  be in  addition  to a  separate  vote  of the  requisite
percentage of Common  Shares and  Preferred  Shares,  including  AMPS,  voting
together as a single class necessary to authorize the action in question.



                                                                        Appendix
